Cerebrospinal fluid asparagine concentrations after Escherichia coli asparaginase in children with acute lymphoblastic leukemia. (1/487)

PURPOSE: The CNS is an important sanctuary site in childhood acute lymphoblastic leukemia (ALL). CSF asparagine concentration reflects asparaginase systemic pharmacodynamics. We evaluated the time course of CSF asparagine depletion in children with ALL during and after a course of Escherichia coli asparaginase. PATIENTS AND METHODS: Thirty-one children (24 newly diagnosed and seven at relapse) received E coli asparaginase 10,000 IU/m2 intramuscularly three times weekly for six and nine doses, respectively, as part of multiagent induction chemotherapy. CSF asparagine levels were measured before, during, and after asparaginase dosing. RESULTS: The percentage of patients with undetectable (< 0.04 micromol/L) CSF asparagine was 3.2% (one of 31 patients) at baseline, 73.9% (17 of 23) during asparaginase therapy, and 56.3% (nine of 16) 1 to 5 days, 43.8% (seven of 16) 6 to 10 days, 20.0% (two of 10) 11 to 30 days and 0% (zero of 21) more than 30 days after asparaginase therapy. The proportion of patients with depleted CSF asparagine was higher during asparaginase therapy than at baseline (P < .001), 11 to 30 days (P = .003), and more than 30 days after asparaginase therapy (P < .001). Median CSF asparagine concentrations were 4.42 micromol/L before, less than 0.04 micromol/L during, and less than 0.04 micromol/L at 1 to 5 days, 1.63 micromol/L at 6 to 10 days, 1.70 micromol/L at 11 to 30 days, and 5.70 micromol/L at more than 30 days after asparaginase therapy, respectively. CSF depletion was more common in patients with low baseline CSF asparagine concentrations (P = .003). CONCLUSION: CSF asparagine concentrations are depleted by conventional doses of E coli asparaginase in the majority of patients, but they rebound once asparaginase therapy is completed.  (+info)

Long-term follow-up results of adult patients with acute lymphocytic leukemia or lymphoblastic lymphoma treated with short-term, alternating non-cross-resistant chemotherapy: Japan Clinical Oncology Group Study 8702. Lymphoma Study Group. (2/487)

BACKGROUND: Patients with acute lymphocytic leukemia (ALL) and those with lymphoblastic lymphoma (LBL) have overlapping clinical and immunophenotypic features and they have been treated with the same or very similar chemotherapy regimens. The goal of this multi-institutional phase II trial was to evaluate the therapeutic efficacy of a short-term, six-drug chemotherapy regimen for adult patients with untreated ALL or LBL. METHODS: Forty-six eligible patients, 41 with ALL and five with LBL, were treated with a short-term (planned total therapy duration; 36-38 weeks), simplified chemotherapy program; two courses of VEPA-L (vincristine, cyclophosphamide, prednisolone, doxorubicin, I-asparaginase plus intrathecal methotrexate and prednisolone) followed by four courses of M-VEPA (methotrexate plus VEPA), without the traditional maintenance therapy using daily 6-mercaptopurine and weekly methotrexate. RESULTS: Thirty-six (78%; 95% confidence interval 64-89%) of the 46 eligible patients achieved complete remission (CR). Among the 36 patients who achieved CR, four (11%) died of treatment complications, 26 (72%) relapsed and six (17%) remain alive in continuous CR. The median survival for all 46 eligible patients is 14 months and the median disease-free survival (DFS) for the 36 patients who achieved CR is 11 months. The estimate of the proportion of survival at 7 years of all 46 eligible patients is 15% at a median follow-up time of 96 months and that of DFS of the 36 patients achieving CR is 17% at a median follow-up time of 93 months. Subgroup analysis showed that an elevated serum C-reactive protein (CRP) level, age of 30 years or older, the presence of B-symptom and T-cell phenotype were likely to be associated with shortened survival. Although the observed CR rate (78%) is within the range of satisfaction, the long-term survival rate (15%) is inferior to those of published programs incorporating maintenance therapy. CONCLUSIONS: A fraction of adult patients with ALL or LBL are curable with a short-term, six-drug chemotherapy regimen. However, this simplified therapy of shorter duration cannot be recommended.  (+info)

Fractionated cyclophosphamide added to the IVAP regimen (idarubicin-vincristine-L-asparaginase-prednisone) could lower the risk of primary refractory disease in T-lineage but not B-lineage acute lymphoblastic leukemia: first results from a phase II clinical study. (3/487)

BACKGROUND AND OBJECTIVE: In a prior study, primary resistant acute lymphoblastic leukemia (RES-ALL) was observed in 11 of 176 (6%) adult patients treated with a four drug regimen (IVAP), its incidence being higher in T-cell or Philadelphia (Ph) chromosome/BCR-ABL rearrangement positive ALL cases with a blast cell count >25x10(9)/L (RES-ALL rate 19%, p=0.04). Aiming to minimize this percentage of resistant disease, fractionated cyclophosphamide (f-CY) was then added to the IVAP regimen. DESIGN AND METHODS: Study 08-96 was a prospective, collaborative phase II trial carried out at eight general hospital centers specialized in the care of hematologic malignancies. Historical IVAP-treated patients served as a retrospective control group. All consecutive, untreated patients (>15 years) with a diagnosis of ALL or advanced-stage lymphoblastic lymphoma (LBL) were eligible. RES-ALL was defined as the persistence of >5% ALL cells in the bone marrow 28-40 days after the start of the IVAP regimen (idarubicin 10 mg/m(2)/d on days 1 and 2; vincristine 2 mg on days 1, 8 and 15; L-asparaginase 6,000 U/m(2) on alternate days 3 6 from day 8; prednisone 60 mg/m(2)/d on days 1-21). In the new study, two f-CY schedules were sequentially adopted: CY 150 or 75 mg/m(2)/bd, given for 4 consecutive days before IVAP (f-CY 1200 or 600, expressing total CY dose in mg/m(2)). RESULTS: Eighty-eight patients were evaluable (age range 15-74 years, blast count 0-240x10(9)/L, 14 T-lineage, 74 B-lineage, 13 Ph/BCR-ABL+). The first 39 patients received the f-CY 1200 schedule, 22 patients received f-CY 600, and the last 27 patients were not given any f-CY. These changes were dictated by the results of interim analyses of the f-CY groups (RES-ALL rate not reduced, myelotoxicity increased). Altogether, compared with the historical IVAP and no f-CY groups, the incidence of RES-ALL was not decreased by the addition of f-CY 1200/600 in B-lineage ALL, regardless of Ph/BCR-ABL expression and blast count. However, none of 14 T-ALL cases in the new study had RES-ALL (8 in f-CY groups, 5 of whom with >25x10(9)/L blast cells), compared to 5/39 (13%, overall) or 4/21 (19%, with >25x10(9)/L blast cells) among the control cases. Owing to small sample size, this difference was not statistically significant. INTERPRETATION AND CONCLUSIONS: This preliminary experience suggests that T-ALL may be more sensitive than B-lineage ALL to an early therapy including f-CY. The hypothesis could be tested in a larger clinical trial.  (+info)

Non-Hodgkin's lymphoma in children: results of treatment with LSA2-L2 protocol. (4/487)

The results obtained with very intensive treatment in previously untreated patients early in the disease are encouraging, and we hope will change the philosophy of most investigators that even in far advanced disease such as those with marrow metastases or multiple primary sites, one can still obtain complete regression at all tumour sites within 1 to 1 1/2 months from onset of therapy by combined treatment with multiple chemotherapeutic agents and radiation therapy to one or more sites.  (+info)

Acute lymphoblastic leukaemia: cyclical chemotherapy with three combinations of four drugs (COAP-POMP-CART regimen). (5/487)

Forty-two adults and children with previously untreated acute lymphoblastic leukaemia (ALL) were entered into a programme of chemotherapy in which three combinations, each of four drugs were administered in a predetermined cyclical rotation together with cranial irradiation and intrathecal injections of methotrexate. Forty-one patients (98%) entered remission and no patient developed neuroleukaemia. Relapse of ALL occurred in 10 patients, and three patients died during remission, while eight patients stopped treatment after two and a half years and have remained in remission for two to 26 months. Comparison of remission and survival experience in this mixed group of children and adults with the experience of children treated at Memphis and in the Medical Research Council's UKALL-I trial showed no significant differences. On the other hand, analysis by prognostic factors showed that neither age nor blast cell count at presentation had any adverse effect in patients treated in this study. No relapses occurred in nine patients with blast cell counts greater than 20 x 109/1 at presentation. This regimen is effective treatment for ALL and may be of special value in patients with poor prognoses. The regiment has not as yet proved superior for the treatment of children with ALL who do not have adverse prognostic features.  (+info)

Applications of synchrotron radiation to protein crystallography: preliminary results. (6/487)

X-ray diffraction photographs of protein single crystals have been obtained using synchrotron radiation produced by an electron-positron storage ring. The diffracted intensities observed with this unconventional source are a factor of at least 60 greater than those obtained with a sealed x-ray tube using the same crystal and instrumental parameters. Diffraction data have been collected by the precession method to higher resolution and using smaller protein crystals than would have been possible with a conventional source. The crystal decay rate in the synchrotron beam for several proteins appears to be substantially less than that observed with Ni-filtered Cu radiation. The tunable nature of the source (which allows selective optimization of anomalous contributions to the scattering factors) and the low angular divergence of the beam make the source very useful for single crystal protein diffraction studies.  (+info)

Hypersensitivity to tobacco antigen. (7/487)

A glycoprotein of molecular weight 18,000 was purified from saline extracts of cured tobacco leaves by ammonium sulfate fractionation, chromatography on Sephadex G-25 and continuous-flow preparative electrophoresis on polyacrylamide gel. Twelve of 31 volunteers (6/15 smokers and 6/16 nonsmokers) exhibited immediate cutaneous hypersensitivity (wheal and flare reactions) when injected intracutaneously with 2 mug of this material. Immunochemically similar material was demonstrated in, and purified from, cigarette smoke condensate and cigarette smoke. The concentration in cigarette smoke condensate ("tar") was determined to be 1.8-3.6 mg/g. Antigenically crossreactive material was also demonstrated in eggplants, green peppers, potatoes, and tomatoes, which, like tobacco, are members of the family Solanaceae.  (+info)

Binding of Clostridium botulinum C2 toxin to asparagine-linked complex and hybrid carbohydrates. (8/487)

Clostridium botulinum C2 toxin is a binary toxin composed of an enzymatic subunit (C2I) capable of ADP-ribosylating actin and a binding subunit (C2II) that is responsible for interaction with receptors on eukaryotic cells. Here we show that binding of C2 toxin depends on the presence of asparagine-linked carbohydrates. A recently identified Chinese hamster ovary cell mutant (Fritz, G., Schroeder, P., and Aktories, K. (1995) Infect. Immun. 63, 2334-2340) was found to be deficient in N-acetylglucosaminyltransferase I. C2 sensitivity of this mutant was restored by transfection of an N-acetylglucosaminyltransferase I cDNA. C2 toxin sensitivity was reduced after inhibition of alpha-mannosidase II. In contrast, Chinese hamster ovary cell mutants deficient in sialylated (Lec2) or galactosylated (Lec8) glycoconjugates showed an increase in toxin sensitivity compared with wild-type cells. Our results show that the GlcNAc residue linked beta-1,2 to the alpha-1,3-mannose of the asparagine-linked core structure is essential for C2II binding to Chinese hamster ovary cells.  (+info)

Abstract: We have studied dose- and time-dependent antitumor and cytotoxic effects of Erwinia carotovora L-asparaginase (ECAR LANS) and Escherichia coli L-asparaginase (MEDAC) on human leukemic cells and human and animal solid tumor cells. We determined the sensitivity of tumor cells to L-asparaginases, as well the effect L-asparaginases on cell growth rate, protein and DNA synthesis per se and with addition of different cytostatics. The data obtained demonstrated that ECAR LANS L-asparaginase suppressed growth of all tested solid tumor cells. Evaluation of leukemic cell number after treatment with L-asparaginases for 24, 48 and 72 h demonstrated that asparagine deficiency did not kill cells but stopped normal cell division and had no effect on protein and DNA synthesis. Cytofluorometric study of solid and leukemic cells demonstrated that the treatment with L-asparaginase for 72 h did not change cell cycle phase distribution and did not increase the number of apoptotic cells. The HL-60 cell line ...
Antibodies against polyethylene glycol (PEG) in healthy subjects raise concerns about the efficacy of pegylated drugs. We evaluated the prevalence of antibodies against PEG among patients with acute lymphoblastic leukemia (ALL) prior to and/or immediately after their first dose of pegylated E.coli asparaginase (PEG-ASNase). Serum samples of 701 children, 673 with primary ALL, 28 with relapsed ALL, and 188 adults with primary ALL were analyzed for anti-PEG IgG and IgM. Measurements in 58 healthy infants served as reference to define cut-points for antibody-positive and -negative samples. Anti-PEG antibodies were detected in ALL patients prior the first PEG-ASNase with a prevalence of 13.9% (anti-PEG IgG) and 29.1% (anti-PEG IgM). After administration of PEG-ASNase the prevalence of anti-PEG antibodies decreased to 4.2% for anti-PEG IgG and to 4.5% for anti-PEG IgM. Pre-existing anti-PEG antibodies did not inhibit PEG-ASNase activity but significantly reduced PEGASNase activity levels in a ...

Growth of Escherichia coli A-l under aerobic conditions in an enriched medium with a total amount of 0.2 per cent glucose was biphasic and asparaginase II activity was detected after depletion of ammonia from the growth medium in the second phase of growth. Glucose was exhausted two hours before ammonia and three hours before asparaginase II activity was detected. The concentration of 3,5-cyclic adenosine monophosphate was found to fluctuate when the dissolved oxygen in the medium reached a low level, when glucose and ammonia were exhausted, and when the cells entered the second stationary phase of growth. Culture tube studies of the growth of E_j_ coli A-l in three per cent nutrient broth with varied concentrations of ammonium chloride and potassium nitrate gave lower specific activity of asparaginase II when this was compared to that seen in three per cent nutrient broth alone. The addition of glucose to the same medium before asparaginase II activity was detected resulted in the production of acid
Hypersensitivity to pegaspargase is associated with inferior survival in pediatric patients with acute lymphoblastic leukemia and lymphoblastic lymphoma. In the past year, drug-supply shortages have led to the lack of an available alternative to pegaspargase. Rather than omit asparaginase from the treatment of acute lymphoblastic leukemia or lymphoblastic lymphoma patients with hypersensitivity to pegaspargase, we continued pegaspargase treatments for nine pediatric patients, utilizing a rapid desensitization protocol. There were no adverse events related to the pegaspargase during desensitization, and all patients who were checked had asparaginase serum levels above the threshold of 0.1 IU/mL at 7 to 14 days after pegaspargase therapy.
l -asparaginase (L-ase) is a major drug used to treat acute lymphoblastic leukemia (ALL) [1]. L-ase kills leukemic cells by depleting circulating asparagine pools related to its asparaginase activity [2]. L-ases from Escherichia coli and Erwinia chrysanthemi also degrade l -glutamine due to their glutaminase activity. Th e primary adverse eff ects of L-ase include hypersensitivity, thrombosis, immunosuppression and cytotoxic eff ects. L-ase also induces liver dysfunction with macroand microvesicular steatosis, which may rapidly lead to liver failure, coma and death [3 - 6]. L-ase-induced liver defects are related to decreased protein synthesis due to a reduction in asparagine and glutamine pools [7,8]. Microvesicular steatosis is the most severe form of liver steatosis and is caused by impairment of mitochondrial β -oxidation, leading to the accumulation of unoxidized fatty acids converted to triglycerides [9]. Th is change is often accompanied or dominated by macrovesicular steatosis, as observed with

Bacterial asparaginases (amidohydrolases, EC 3.5.1.1) are important enzymes in cancer therapy, especially for Acute Lymphoblastic Leukemia. They are tetrameric enzymes able to catalyze the deamination of L-ASN and, to a variable extent, of L-GLN, on which leukemia cells are dependent for survival. In contrast to other known L-asparaginases, Helicobacter pylori CCUG 17874 type II enzyme (HpASNase) is cooperative and has a low affinity towards L-GLN. In this study, some critical amino acids forming the active site of HpASNase (T16, T95 and E289) have been tackled by rational engineering in the attempt to better define their role in catalysis and to achieve a deeper understanding of the peculiar cooperative behavior of this enzyme. Mutations T16E, T95D and T95H led to a complete loss of enzymatic activity. Mutation E289A dramatically reduced the catalytic activity of the enzyme, but increased its thermostability. Interestingly, E289 belongs to a loop that is very variable in L-asparaginases from the

The antileukemic activity of l-asparaginase (ASNase), an important component of therapy for acute lymphoblastic leukemia, is thought to result from depletion of serum l-asparagine (Asn). In studies of the pharmacological effects of ASNase, investigators have reported prolonged reduction in the serum concentration of Asn after the administration of ASNase. Such measurements may not be valid because ASNase present in the blood sample may hydrolyze Asn before its determination. We examined recovery of [U-14C]Asn from blood samples with and without various concentrations of added ASNase. In the presence of ≥0.01 IU/ml of ASNase, the amount of [U-14C]Asn recovered was ,15% of that without ASNase. Utilizing this assay, we studied the effect of 2 known inhibitors of ASNase in an attempt to improve Asn recovery. In the presence of aspartic β semialdehyde (ASA), or 5-diazo-4-oxo-l-norvaline (DONV), and up to 1.0 IU/ml ASNase, Asn levels remained at ,90% of control. ASA prevented the hydrolysis of ...

The present protocol will compare the biologic effects of PEG-asparaginase vs native-forms of asparaginase in a randomized trial using the same dosages and schedules used in the POG 9411 study. Comprehensive studies, including the measurement of antibodies and asparagine levels as well as the pharmacokinetics of L-asparaginase, will be performed. This protocol will also study the changes in topoisomerase I and topoisomerase II levels and the fractions of topoisomerase I/II translocations in malignant lymphoblasts after upfront window topotecan therapy, and correlate oncolytic response with these changes. Secondary objectives include: - To compare changes in asparagine levels 28 days after initiation of treatment with asparaginase between the two groups. - To estimate the pharmacokinetics of L-asparaginase, compare the pharmacokinetics between the two groups of patients, and correlate the pharmacokinetics with the development of antibody to asparaginase and depletion of asparagine. - To measure ...

l-Asparaginase is a key therapeutic agent for treatment of childhood acute lymphoblastic leukemia (ALL). There is wide individual variation in pharmacokinetics, and little is known about its metabolism. The mechanisms of therapeutic failure with l-asparaginase remain speculative. Here, we now report that 2 lysosomal cysteine proteases present in lymphoblasts are able to degrade l-asparaginase. Cathepsin B (CTSB), which is produced constitutively by normal and leukemic cells, degraded asparaginase produced by Escherichia coli (ASNase) and Erwinia chrysanthemi. Asparaginyl endopeptidase (AEP), which is overexpressed predominantly in high-risk subsets of ALL, specifically degraded ASNase. AEP thereby destroys ASNase activity and may also potentiate antigen processing, leading to allergic reactions. Using AEP-mediated cleavage sequences, we modeled the effects of the protease on ASNase and created a number of recombinant ASNase products. The N24 residue on the flexible active loop was identified as ...

Although dyslipidemia has been reported during ALL therapy, there have been few systematic studies, and no prior study with dex pharmacokinetics (PK) or asparaginase biomarkers. We studied serum high density lipoprotein (HDL), low density lipoprotein (LDL), triglycerides, and cholesterol in 313 pediatric ALL patients enrolled on St. Jude Total XV at baseline (day 15 consolidation), and weeks (wks) 7, 8 and 12 of continuation therapy. Patients on the standard/high risk (SHR) arm (n=163) were exposed to more asparaginase (wks 1-12) than those on the low risk (LR) arm (n=150, wks 7-9) as reflected by lower serum albumin at wks 7, 8, and 12 (p ,10-6, all time points).

Background: Hyperglycaemia is a common side effect of steroid and L-asparaginase combinations, occurring mostoften during acute lymphoblastic leukemia (ALL) induction phase. To date in Indonesia, it has not been obtained dataon the incidence of hyperglycemia in children with ALL in the induction phase and how the role of combinations ofL-asparaginase and different type of steroid used. The purpose of this study is to determine the incidence of hyperglycemiain children ALL induction phase, knowing the difference between prednisone and dexamethasone (in combination withL-asparaginase) in causing hyperglycemia in children with ALL and determine the relationship of other factors relatedto hyperglycaemia. Methods: This was a prospective analytic study with a pre- and post-test design, conducted inthree hospitals (Cipto Mangunkusumo Hospital, Dharmais Cancer Hospital, and Gatot Soebroto Hospital). Patientsblood glucose levels were checked at the 3rd (pretest), 4th, 5th and 6th week of protocol (post-test).

Targeting amino acid metabolism has therapeutic implications for aggressive brain tumors. Asparagine is an amino acid that is synthesized by normal cells. However, some cancer cells lack asparagine synthetase (ASNS), the key enzyme for asparagine synthesis. Asparaginase (ASNase) contributes to eradication of acute leukemia by decreasing asparagine levels in serum and cerebrospinal fluid. However, leukemic cells may become ASNase-resistant by up-regulating ASNS. High expression of ASNS has also been associated with biological aggressiveness of other cancers, including gliomas. Here, the impact of enzymatic depletion of asparagine on proliferation of brain tumor cells was determined. ASNase was used as monotherapy or in combination with conventional chemotherapeutic agents. Viability assays for ASNase-treated cells demonstrated significant growth reduction in multiple cell lines. This effect was reversed by glutamine in a dose-dependent manner -- as expected, because glutamine is the main amino ...
We found that the mechanism by which perphenazine was killing cancer cells was independent of its antipsychotic activity, says Gutierrez, who was a fellow in Looks laboratory and who has recently established his own lab at Dana-Farber/Boston Childrens. When we looked more closely, we found that the drug also activated a tumor-suppressing protein called PP2A.. This is unusual. In general, anticancer drug research seeks to find proteins that are active only in cancer cells and develop ways to shut them off. But perphenazine was doing the opposite: In reactivating PP2A, the drug was reactivating a protein that the tumor cells had turned off, triggering the cells to die.. In other words, perphenazine was relieving the suppression on the suppressor, thereby forcing cancer cells in the model to die.. We rarely find potential drug molecules that activate an enzyme, Gutierrez explains. But, here, perphenazine is restoring the activity of PP2A in the T-ALL cell.. Perphenazine was relieving the ...

The ansa cervicalis, also called ansa hipoglossi, is a U-shaped, curved stretch of nerve, which is part of the cervical plexus. It is formed by myelinated nerve fibers coming from spinal roots C1, C2, and C3. From the loop of the ansa cervicalis, three nerves projects downward to innervate the sternothyroid, the sternohyoid, and the omohyoid muscles. ...
Exocytotic secretion of digestive enzymes from pancreatic acinar cells is elicited by physiological cytosolic Ca2+ signals, occurring as repetitive short-lasting spikes largely confined to the secretory granule region, that stimulate mitochondrial adenosine triphosphate (ATP) production. By contrast, sustained global cytosolic Ca2+ elevations decrease ATP levels and cause necrosis, leading to the disease acute pancreatitis (AP). Toxic Ca2+ signals can be evoked by products of alcohol and fatty acids as well as bile acids. Here, we have investigated the mechanism by which l-asparaginase evokes AP. Asparaginase is an essential element in the successful treatment of acute lymphoblastic leukaemia, the most common type of cancer affecting children, but AP is a side-effect occurring in about 5-10% of cases. Like other pancreatitis-inducing agents, asparaginase evoked intracellular Ca2+ release followed by Ca2+ entry and also substantially reduced Ca2+ extrusion because of decreased intracellular ATP ...
David M. Jackman, MD from Dana-Farber Cancer Institute recently answered your questions on lung cancer as part of CancerConnects Guest Moderator Ask the Expert series. Dr. Jackman is a thoracic oncologist in the Lowe Center for Thoracic Oncology at Dana-Farber Cancer Institute.. Question: My sister has stage 3 lung cancer and presented with anemia, nausea and weight loss. They didnt want to treat her until they figured out what was going on with the nausea so we waited for 2 months while they did tests. Now they are finally moving, but still dont know why she is anemic and can barely eat. We meet with the radiation oncologist Friday and want to know what to ask. Is there a specific kind of treatment modality we should be asking about? Tomotherapy, cyberknife, proton therapy? I just dont know enough about it. We are near enough to Chicago that we have everything available, just want to make sure our physician offers the best option.. Dr. Jackmans Response: When we think about Stage III lung ...
Scientists may have found a new tool for studying-and maybe even treating-Type 2 diabetes.. A team of scientists from the Florida campus of The Scripps Research Institute (TSRI), Dana-Farber Cancer Institute, Harvard Medical School and the Yale University School of Medicine have identified a new class of compounds that reduce production of glucose in the liver. One of these compounds, designed and optimized by TSRI scientists, significantly improves the health of diabetic animal models by reducing glucose levels in the blood, increasing insulin sensitivity, and improving glucose balance.. The study, published recently in the journal Cell, was led by Pere Puigsever of Harvard Medical School and the Dana-Farber Cancer Institute.. The compound they identified, called SR-18292, modifies a protein known as PGC-1α. This protein plays a pivotal role in energy balance and helps control genes involved in energy metabolism. When cells overexpress PGC-1, during fasting or starvation, for example, glucose ...

This is an extraordinary result, said George Demetri, MD, professor of medicine at Harvard Medical School, director of the Ludwig Center at Dana-Farber/Harvard Cancer Center, and director of the Center for Sarcoma and Bone Oncology at Dana-Farber Cancer Institute, in a Forbes interview. Lots of doctors dont realize theres a possibility that their patients might have this genetic change. They dont screen for TRK mutations, so 9 in 10 cancer patients who might benefit from this drug likely dont have the opportunity to try it.. Progress with larotrectinib is along the lines of Demetris prediction in a post to forecast cancer therapy advances in 2017. In an interview for that post, he said it is good news that we are still uncovering virtually monogenic diseases-diseases that are driven by single oncogenic fusions or mutations, referring to NTRK fusions. Therapies targeting single mutations, such as NTRK fusions, lead to durable and dramatic responses, added Demetri, who is a board member ...

Acute pancreatitis (AP), a human disease in which the pancreas digests itself, has substantial mortality with no specific therapy. The major causes of AP are alcohol abuse and gallstone complications, but it also occurs as an important side effect of the standard asparaginase-based therapy for childhood acute lymphoblastic leukemia. Previous investigations into the mechanisms underlying pancreatic acinar cell death induced by alcohol metabolites, bile acids, or asparaginase indicated that loss of intracellular ATP generation is an important factor. We now report that, in isolated mouse pancreatic acinar cells or cell clusters, removal of extracellular glucose had little effect on this ATP loss, suggesting that glucose metabolism was severely inhibited under these conditions. Surprisingly, we show that replacing glucose with galactose prevented or markedly reduced the loss of ATP and any subsequent necrosis. Addition of pyruvate had a similar protective effect. We also studied the effect of ...
US scientists have identified a way in which cancer cells can become resistant to the cancer drug cetuximab (Erbitux), and suggest that treatments that are already available might be able to overcome this resistance.. Researchers from the Dana-Farber Cancer Institute in Boston, US, have been studying why some patients only experience short-term benefits with cetuximab, or none at all.. Cetuximab is an antibody that interferes with cancer cell growth. It can be given in combination with chemotherapy to patients with bowel cancer or head and neck cancer.. Until now, scientists didnt know why some cancers failed to respond to the drug, or initially responded but then became resistant.. The new study, published in Science Translational Medicine, found that in some of the drug-resistant cells, a protein known as ErbB2 (also known as HER2/neu) was sending grow signals.. These were bypassing the stop growing signals caused by the drug.. Pasi Janne, the studys co-senior author, said: ErbB2 ...
4:00 KEYNOTE PRESENTATION: TMB/GEP Dual Biomarker Strategy for Personalized Checkpoint Blockade Combination Immunotherapy. Jianda Yuan, MD, PhD, Senior Director, Translational Oncology, Merck. Immune checkpoint blockade therapies are revolutionizing the standard cancer treatment. Despite the current success of these therapies, not all patients respond to immunotherapy. Combination approaches are the keys to improving clinical response. Tumor mutational burden (TMB) and gene expression profile (GEP) are emerging biomarkers predicting patient response. Dual TMB/GEP biomarkers allow us to understand novel translational biomarkers to stratify patients effectively for personalized cancer immunotherapy.. 4:30 Is There a Role for Biomarkers in this Era of Combination Immunotherapy?.

PHILADELPHIA - An increasing body mass index was associated with a higher risk for colorectal cancer with a specific molecular characteristic, and inversely, physical activity was linked to a decreased risk for that same cancer, according to data published in Cancer Research, a journal of the American Association for Cancer Research.. We know that exercise and avoiding obesity decrease colorectal cancer risk, but little is known about why, said Shuji Ogino, M.D., Ph.D., associate professor of pathology at Dana-Farber Cancer Institute and associate professor in the Department of Epidemiology at Harvard School of Public Health in Boston, Mass. In this study, we used a biomarker named CTNNB1, which is a molecule implicated in cancer and obesity, to divide patients into two groups, CTNNB1-positive and CTNNB1-negative.. Ogino and colleagues used data from more than 100,000 women from the Nurses Health Study and more than 45,000 men in the Health Professionals Study to examine whether there was ...

Scientists who studied a highly cancer-prone single family have identified a rare, inherited gene mutation that may raise the lifetime risk of pancreatic and other cancers. Their findings were published by Nissim et al in Nature Genetics.. The discovery of the previously unknown mutation could lead to routine testing of individuals with a strong family history of pancreatic cancer to determine if they carry a mutation occurring in the gene RABL3. If so, they could be screened to detect pancreatic cancer in an earlier, potentially more treatable stage. In addition, their relatives could choose to be tested to learn if they carry the mutation.. There is evidence that catching pancreatic cancer through screening of high-risk individuals may improve outcomes, said first study author Sahar Nissim, MD, PhD, a cancer geneticist and gastroenterologist at Dana-Farber Cancer Institute and Brigham and Womens Hospital. About 10% of pancreatic cancers have a familial pattern, and in most cases, the ...

The ASCO Post asked several myeloma experts their views on the investigational agents that could make Dr. Andersons prediction a reality. Their thoughts on antibody-based treatments follow. (See page 21 for their perspectives on the new proteasome inhibitors in multiple myeloma.). We eagerly await monoclonal antibody-based therapy in myeloma, as we have had for years in lymphoma. These agents attack the plasma cell in a different way, and, encouragingly, what we heard at ASH is that they are not only tolerable but effective. They will certainly be additive to our arsenal, said Sonja Zweegman, MD, PhD, of VU University Medical Center in Amsterdam, The Netherlands, who moderated a session on new agents in myeloma.. Elotuzumab. Paul G. Richardson, MD, of Dana-Farber Cancer Institute, Boston, agreed. As we all know, recognizing the complex biology of myeloma, we need more treatment options, he said.. Echoing Dr. Zweegmans excitement over monoclonal antibodies, he commented, We saw great data ...
The heavier a person is and the less exercise he or she does, the greater the likelihood of developing a specific type of colorectal cancer, a new study finds.. Researchers at the Dana-Farber Cancer Institute in Boston analyzed data on weight and physical activity from questionnaires sent every two years to more than 109,046 women who participated in the landmark Nurses Health Study, an ongoing study about womens health that is following nurses. The questionnaires also went to more than 47,684 men who participated in the Health Professionals Follow-Up Study, an ongoing study about mens health that includes more than 50,000 men who work in health care. Data collection began in 1976 for the women and in 1986 for the men.. When follow-up ended in June 2004, 2,263 cases of colorectal cancer - 842 in men and 1,421 in women - had been diagnosed. The researchers analyzed 861 of the cancers to determine if any contained a molecular biomarker, called CTNNB1, which has been linked to cancer and ...
The Albert and Mary Lasker Foundation honored three distinguished physician-scientists with a coveted award for their independent, groundbreaking research that led to the discovery of HIF1 and explained how the protein drives physiologic changes in response to hypoxia. Such changes can play a role in cancer progression and the development of other medical conditions.. Gregg L.

The prize was bestowed during a September 23 ceremony in New York, NY.. In the early 1990s, Semenza was trying to explain how hypoxia triggers the production of erythropoietin, promoting the formation of red blood cells, which carry oxygen. Through a series of ...
For the first time, researchers have laid bare the full genetic blueprint of multiple prostate tumors, uncovering alterations that have never before been detected and offering a deep view of the genetic missteps that underlie the disease. The study, made possible by key advances in whole genome sequencing and analysis, points to several new prostate cancer genes and a critical category of genomic changes as important drivers of prostate cancer growth. The work was led by researchers from the Broad Institute, Dana-Farber Cancer Institute and Weill Cornell Medical College and appears in the February 10th issue of the journal Nature.. Unlike other sequencing methods that target specific sections of the genome, whole genome sequencing enables researchers to look across the entire DNA landscape of a tumor, making it possible to discern global changes and patterns. Senior authors Levi Garraway and Mark Rubin and their colleagues used this strategy to view the complete genomes of seven prostate tumors ...
The New York Times]. Over the past few decades, changes in the treatment of breast cancer amount to a revolution in patient care. And its not over yet. There was a time when the standard approach was a radicalmastectomy, which involved removal of not just the breast, but all the lymph nodes in the armpit and underlying muscles in the chest wall. This approach has been replaced by less extensive surgery that, through decades of clinical trials, has proved to be equally effective at treating patients, as well as safer and less disfiguring. Even simple mastectomies, in which most nodes and the muscles were left intact, have become far less common. Dr. J. Dirk Iglehart, director of the Susan F. Smith Center for Womens Cancers at Dana-Farber Cancer Institute in Boston, estimated that he now performs a tenth of the number of mastectomies than when he entered the field in the 1970s.. Currently, most women with early-stage breast cancer have alumpectomy; only the tumor and a small margin of ...
Background: Evidence suggests that the experience of cancer differs across racial and ethnic underserved populations. We describe the referral patterns and clinical characteristics of patients receiving care at Dana-Farber Cancer Institutes clinical outreach community cancer program, an initiative established to improve access to quality cancer care across the spectrum of the disease for medically underserved patients.. Methods: Two hundred and twenty five patients, receiving care at our community cancer care site, based within a Federally Qualified Health Center in Boston, were consented to research and enrolled between January 2012 and June 2015. The program accommodates all oncology and hematology referrals from primary care providers (PCP) at the health center. Variables of interest were collected through medical chart review and a patient intake survey that was developed for the program, and included age, gender, ethnicity, health insurance coverage, reasons for referral, presence of ...

Inivata announces that new clinical data from its collaboration with Dana-Farber Cancer Institute will be presented at the World Conference on Lung Cancer (WCLC).. The study involved a blind retrospective evaluation of Inivatas InVision ctDNA liquid biopsy analysis to characterise and monitor the molecular profile of advanced non-small cell lung cancer (NSCLC) during genotype-directed therapy with osimertinib.. Inivatas technology was shown to detect a full range of genotypes, including gene rearrangements, with an exquisite sensitivity and a high specificity. It was able to detect ALK and ROS1 fusions with high sensitivity, the first time this has been shown using amplicon sequencing. As published previously, there was excellent concordance with droplet digital PCR (ddPCR).. Commenting on ...
In a Nature Letters article published in July 2017, a group from the Dana-Farber Cancer Institute led by Catherine Wu reported an exciting proof-of-principle study showing that a personal neoantigen vaccine is safe, strongly immunogenic, and capable of inducing tumor-reactive T cells.. Ott et al. Nature Letters 2017 used whole-exome sequencing of DNA from matched tumor and normal cells to identify somatic mutations and used HLA binding prediction algorithms to create personalized HLA-binding peptide sequences. Corresponding peptides were synthesized and used as immunogens administered with poly-ICLC in patients with previously untreated high-risk melanoma in a phase I study.. In conjunction with flow cytometry, the authors used Mabtech IFN-γ ELISpot assays to show that personalized neoantigen vaccines generate polyfunctional CD4- as well as CD8-specific T cell responses that persisted over time. They also showed that subsequent checkpoint blockade therapy (anti-PD1 mAb pembrolizumab) broadens ...

John Heymach, MD: The RELAY study compared erlotinib and ramucirumab versus erlotinib with placebo.. Whats the preclinical rationale for the RELAY study? Well, its been known for some time that tumors with EGFR mutations upregulate VEGF and the VEGF pathway. This appears to be, at least in part, through something called the HIF pathway. HIF stands for hypoxia-inducible factor.. Normally when cells have low oxygen, they turn on this HIF pathway, and that turns on all these factors that help the cells survive. In fact, the Nobel Prize in Physiology or Medicine this past year was awarded for understanding the mechanisms underlying this HIF pathway. It was awarded to Bill Kaelin, MD at Dana-Farber Cancer Institute, as well as Peter John Ratcliffe, FRS, FMedSci and Gregg Semenza, MD, PhD, whos at Johns Hopkins Medicine for showing how this mechanism works.. Tumors with an EGFR mutation, when you turn on this HIF pathway, that leads to VEGF getting upregulated. Theyre highly dependent on the VEGF ...
For the last decade, advanced renal cell carcinoma (RCC) has been at the forefront of oncologic innovation. While there is extensive imaging research on RCC, the important themes that could shape the future of RCC imaging revolve around the use of imaging as a biomarker to predict the make-up and behavior of the disease. In an article published online in Radiology(RSNA.org/Radiology), Atul B. Shinagare, MD, of the Dana-Farber Cancer Institute, Boston, and colleagues review developments in management of advanced RCC from a radiologists perspective with the aim of enhancing the specialtys value in clinical management. Specifically, the authors describe:. • How the underlying molecular mechanisms of RCC provide specific targets for novel anticancer agents. • The relationship between the mechanisms of action of the novel anticancer agents and the imaging appearance of tumor response • Available tumor response criteria and their strengths and weaknesses. The authors also summarize the class- ...

Excerpted from Study finds spiritual care still rare at end of life, Chicago Tribune, by Kathleen Raven. December 26, 2012--Physicians and nurses at four Boston medical centers cited a lack of training to explain why they rarely provide spiritual care for terminally ill cancer patients - although most considered it an important part of treatment at the end of life. I was quite surprised that it was really just lack of training that dominated the reasons why, senior author Dr. Tracy Balboni, a radiation oncologist at the Dana-Farber Cancer Institute in Boston, told Reuters Health. Current U.S. palliative care guidelines encourage medical practitioners to pay close attention to religious and spiritual needs that may arise during a patients end-of-life care. However, the 204 physicians who participated in the study reported providing spiritual care to just 24 percent of their patients. Among 118 nurses, the figure was 31 percent. The 69 patients with advanced cancers who took the survey ...

Researchers from the Dana-Farber Cancer Institute [1] engineered telomerase-deficient mice by knocking out the TERT gene, which codes the telomerase enzyme. These mice, inbred through several generations, showed considerable damage to several organs, tissue atrophy, and half the life span of normal mice. The researchers then devised a clever way to reactivate the enzyme by activating TERT transcription only in the presence of a molecule called 4-OHT. In the presence of 4-OHT, in vitro cell cultures showed that the telomerese ends lengthened and cell proliferation resumed. Furthermore, after a 4-week treatment with the 4-OHT molecule, the degenerative damage induced by the lack of telomerase in the the knock-out mice was considerably reversed and their life span lengthened ...

|br /| David Reardon, M.D., clinical director at the Center for Neuro-oncology at the Dana-Farber Cancer Institute, breaks down a common misconception that many people have about glioblastoma (GBM).
Results A total of 94 cases (48 boys and 46 girls) of AP, clinician-diagnosed from April 2013 to April 2014, fulfilled the diagnostic criteria. The median age of diagnosis was 11.2 years (range 1.30-14.89 years). White children accounted for 60% of cases compared to 40% from ethnic minorities (71% Asian and 13% Black). Pakistani children alone made up 19% of the cohort. The reported incidence of AP in children under age 15 in the UK was 0.78 per 100,000 (95% CI 0.62-0.96). Of the 94 cases: 36 (38%) were idiopathic, drugs 18 (19%), gallstones 12 (13%), hereditary 7 (7.5%), organic acidaemia 7 (7.5%), anatomical anomalies 4 (4%), viral infections 3 (3%), vasculitis 3 (3%), trauma 1 (1%) and others 3 (3%). The most common drug associations were asparaginase (28%), azathioprine (17%) and sodium valproate (17%). Of the 12 gallstone-associated cases, 5 were boys; body weight of 5 cases were above the 91st centile (4 were above the 98th centile). Overall, 6 of 7 organic acidaemia cases (86%) and 3 of 5 ...
