Neoplasms located in the bone marrow. They are differentiated from neoplasms composed of bone marrow cells, such as MULTIPLE MYELOMA. Most bone marrow neoplasms are metastatic.
The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.

The continuous turnover of BONE MATRIX and mineral that involves first an increase in BONE RESORPTION (osteoclastic activity) and later, reactive BONE FORMATION (osteoblastic activity). The process of bone remodeling takes place in the adult skeleton at discrete foci. The process ensures the mechanical integrity of the skeleton throughout life and plays an important role in calcium HOMEOSTASIS. An imbalance in the regulation of bone remodeling's two contrasting events, bone resorption and bone formation, results in many of the metabolic bone diseases, such as OSTEOPOROSIS.

Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. The second neoplasm may have the same or different histological type and can occur in the same or different organs as the previous neoplasm but in all cases arises from an independent oncogenic event. The development of the second neoplasm may or may not be related to the treatment for the previous neoplasm since genetic risk or predisposing factors may actually be the cause.

Bone marrow scintigraphy using technetium-99m antigranulocyte antibody in malignant lymphomas. (1/285)

BACKGROUND: The purpose of this study was to elucidate the clinical reliability of immunoscintigraphy (IS) to detect infiltration of the bone marrow in patients with malignant lymphoma. PATIENTS AND METHODS: Whole body IS was performed in 103 patients with Hodgkin's disease (HD) or non-Hodgkin's lymphoma (NHL) using Tc-99m labelled anti-NCA-95 which allows visualization of the granulopoietic bone marrow. Of these, 52% were studied prior to any therapy. Findings were compared to posterior iliac crest biopsy as well as MRI and/or follow-up examination. Criteria of marrow infiltration were a positive biopsy, positive follow-up, or positive results of MRI. RESULTS: Comparison of IS and biospy revealed concordant findings in 69 and discordant findings in 34 of 103 patients. Of the 34 patients with discordant results, IS showed lesions suspicious of bone marrow infiltration in 29 patients despite normal biopsy findings. When follow-up and additional examinations were taken into consideration, 10 patients remained with probably false positive and five with false negative IS findings. IS proved to be highly sensitive and specific in patients with HD (100% and 84%, respectively) and high-grade NHL (93% and 84%, respectively). Moderate sensitivity (60%) was found in low-grade NHL. This was possibly due to false negative IS in three to five patients with chemotherapy in contrast to one of five false negative results in patients without chemotherapy. CONCLUSION: Bone marrow scintigraphy using antigranulocyte antibodies is highly sensitive in HD and high-grade NHL. Positive findings in IS subsequent to a negative biopsy should be followed by guided re-biopsy or MRI.  (+info)

Detection of focal myeloma lesions by technetium-99m-sestaMIBI scintigraphy. (2/285)

BACKGROUND AND OBJECTIVE: The tracer tachnetium-99m-2-methoxy-isobutyl-isonitrile (Tc99m-sestaMIBI) has recently been shown to concentrate in some neoplastic tissues, including myeloma. We investigated the diagnostic capacity and limits of this procedure in tracing focal myeloma lesions, and compared them with those of conventional radiological procedures (Xr). DESIGN AND METHODS: We studied 55 patients suffering from multiple myeloma (MM) or solitary plasmacytoma in different stages and clinical conditions, or from monoclonal gammopathy of undefined significance (MGUS), by whole body scans obtained 10 minutes after injection of 555 MBq of Tc99m-sestaMIBI. Scans were defined as normal (physiological uptake only), diffuse (presence of bone marrow uptake), or focal (localized areas of uptake), and were compared to conventional skeletal Xr. RESULTS: Thirty patients showed no focal areas of Tc99m-sestaMIBI uptake; this group consisted of 5 patients with MGUS, 6 with MM in stage IA and 2 in stage IIA, 11 patients studied after effective chemotherapy and 6 in early relapse. Twenty-five patients showed one or more spots of focal uptake: all of them had active disease (untreated, resistant or relapsing MM). In the setting of tracing focal lesions, Tc99m-sestaMIBI scans were concordant with the radiological examination in 38 patients and discordant in 17. Among the latter, in 4 cases Tc99m-sestaMIBI revealed focal lesions not detected by Xr, and in 13 cases lytic areas detected by Xr did not show Tc99m-sestaMIBI uptake. INTERPRETATION AND CONCLUSIONS: In untreated patients, the number of lesions revealed by Tc99m-sestaMIBI was comparable to that shown by Xr, while in pretreated patients Tc99m-sestaMIBI traced a number of lesions lower than that detected by Xr. The reason for this discrepancy is that Tc99m-sestaMIBI traces only active lesions. Tc99m-sestaMIBI limitations in identifying focal lesions may derive from the dimension of the smallest traceable lesion (about one centimeter), and from the possibility that focal plasma cell localizations in collapsed bone may not be visualized due to inadequate vascularization. Tc99m-sestaMIBI scintigraphy is an interesting tool for diagnosing, staging and following up focal myeloma lesions, in the bone as well as in soft tissues. It is more specific than conventional Xr in identifying sites of active disease.  (+info)

Stage III and oestrogen receptor negativity are associated with poor prognosis after adjuvant high-dose therapy in high-risk breast cancer. (3/285)

We report on the efficacy and toxicity of a sequential high-dose therapy with peripheral blood stem cell (PBSC) support in 85 patients with high-risk stage II/III breast cancer. There were 71 patients with more than nine tumour-positive axillary lymph nodes. An induction therapy of two cycles of ifosfamide (total dose, 7.5 g m(-2)) and epirubicin (120 mg m(-2)) was given, and PBSC were harvested during G-CSF-supported leucocyte recovery following the second cycle. The PBSC-supported high-dose chemotherapy consisted of two cycles of ifosfamide (total dose, 12,000 mg m(-2)), carboplatin (900 mg m(-2)) and epirubicin (180 mg m(-2)). Patients were autografted with a median number of 3.7 x 10(6) CD34+ cells kg(-1) (range, 1.9-26.5 x 10(6)) resulting in haematological reconstitution within approximately 2 weeks following high-dose therapy. The toxicity was moderate in general, and there was no treatment-related toxic death. Twenty-one patients relapsed between 3 and 30 months following the last cycle of high-dose therapy (median, 11 months). The probability of disease-free and overall survival at 4 years were 60% and 83%, respectively. According to a multivariate analysis, patients with stage II disease had a significantly better probability of disease-free survival (74%) in comparison to patients with stage III disease (36%). The probability of disease-free survival was also significantly better for patients with oestrogen receptor-positive tumours (70%) compared to patients with receptor-negative ones (40%). Bone marrow samples collected from 52 patients after high-dose therapy were examined to evaluate the prognostic relevance of isolated tumour cells. The proportion of patients presenting with tumour cell-positive samples did not change in comparison to that observed before high-dose therapy (65% vs 71%), but a decrease in the incidence and concentration of tumour cells was observed over time after high-dose therapy. This finding was true for patients with relapse and for those in remission, which argues against a prognostic significance of isolated tumour cells in bone marrow. In conclusion, sequential high-dose chemotherapy with PBSC support can be safely administered to patients with high-risk stage II/III breast cancer. Further intensification of the therapy, including the addition of non-cross resistant drugs or immunological approaches such as the use of antibodies against HER-2/NEU, may be envisaged for patients with stage III disease and hormone receptor-negative tumours.  (+info)

Selection for androgen receptor mutations in prostate cancers treated with androgen antagonist. (4/285)

The role of androgen receptor (AR) mutations in androgen-independent prostate cancer (PCa) was determined by examining AR transcripts and genes from a large series of bone marrow metastases. Mutations were found in 5 of 16 patients who received combined androgen blockade with the AR antagonist flutamide, and these mutant ARs were strongly stimulated by flutamide. In contrast, the single mutant AR found among 17 patients treated with androgen ablation monotherapy was not flutamide stimulated. Patients with flutamide-stimulated AR mutations responded to subsequent treatment with bicalutamide, an AR antagonist that blocks the mutant ARs. These findings demonstrate that AR mutations occur in response to strong selective pressure from flutamide treatment.  (+info)

Detection and clinical importance of micrometastatic disease. (5/285)

Metastatic relapse in patients with solid tumors is caused by systemic preoperative or perioperative dissemination of tumor cells. The presence of individual tumor cells in bone marrow and in peripheral blood can be detected by immunologic or molecular methods and is being regarded increasingly as a clinically relevant prognostic factor. Because the goal of adjuvant therapy is the eradication of occult micrometastatic tumor cells before metastatic disease becomes clinically evident, the early detection of micrometastases could identify the patients who are most (and least) likely to benefit from adjuvant therapy. In addition, more sensitive methods for detecting such cells should increase knowledge about the biologic mechanisms of metastasis and improve the diagnosis and treatment of micrometastatic disease. In contrast to solid metastatic tumors, micrometastatic tumor cells are appropriate targets for intravenously applied agents because macromolecules and immunocompetent effector cells should have access to the tumor cells. Because the majority of micrometastatic tumor cells may be nonproliferative (G0 phase), standard cytotoxic chemotherapies aimed at proliferating cells may be less effective, which might explain, in part, the failure of chemotherapy. Thus, adjuvant therapies that are aimed at dividing and quiescent cells, such as antibody-based therapies, are of considerable interest. From a literature search that used the databases MEDLINE(R), CANCERLIT(R), Biosis(R), Embase(R), and SciSearch(R), we discuss the current state of research on minimal residual cancer in patients with epithelial tumors and the diagnostic and clinical implications of these findings.  (+info)

Sensitive fluorescent in situ hybridisation method for the characterisation of breast cancer cells in bone marrow aspirates. (6/285)

AIM: The presence of malignant cells in the blood and bone marrow of patients with cancer at the time of surgery may be indicative of early relapse. In addition to their numbers, the phenotypes of the micrometastatic cells might be essential in determining whether overt metastases will develop. This study aimed to establish a sensitive method for the detection and characterisation of malignant cells present in bone marrow. METHODS: In spiking experiments, SKBR3 cells were mixed with mononuclear cells in known proportions to mimic bone marrow samples with micrometastatic cells. Tumour cells were extracted using SAM-M450 Dynabeads coupled to the MOC-31 anti-epithelial antibody, and were further analysed for amplification of erbB2 and int2 by fluorescent in situ hybridisation (FISH). erbB2 and int2 copy numbers were also determined in 15 primary breast cancers, and bone marrow samples from patients with amplification were analysed for micrometastatic cells by immunomagnetic enrichment and FISH. RESULTS: In model experiments, cells with amplification could be detected in bead selected fractions when ratios of tumour cells (SKBR3) to mononuclear cells were as low as 10:10(7). Among the tumour samples, eight showed increased copy numbers of erbB2 and/or int2, and three of these patients had detectable numbers of tumour cells in their bone marrow: 4000, 540, and 26 tumour cells/10(7) mononuclear cells, respectively. The patient with 540 tumour cells/10(7) mononuclear cells showed high level amplification of erbB2 and suffered from a particularly aggressive disease, whereas the patient with 4000 tumour cells/10(7) mononuclear cells had favourable disease progression. CONCLUSION: These results demonstrate the feasibility and advantage of combining immunomagnetic selection and FISH characterisation of cancer cells in bone marrow samples. It is possible that molecular characterisation of such cells could provide prognostically valuable information.  (+info)

Cellular proliferation and prevalence of micrometastatic cells in the bone marrow of patients with clinically localized prostate cancer. (7/285)

The presence of prostate cancer cells in the bone marrow (BM) of patients with clinically localized disease is associated with an increased chance of disease recurrence; however, not all patients develop recurrence. We therefore sought to determine the phenotype of individual micrometastatic cells as a potential method to better predict disease outcome. Immunostaining was performed on BM cells from 46 patients whose BM RNA fraction had been identified to contain prostate-specific antigen mRNA. The prevalence of micrometastatic cells among BM mononuclear cells was determined using an anticytokeratin antibody. Mib-1 antibody was used to determine the percentage of micrometastatic cells that were proliferating. Micrometastatic cells were found in 96% of patient samples, with a 30-fold variation in prevalence ranging from 0.1-3.26/10(5) BM cells. Prior androgen ablation was associated with a reduced prevalence of micrometastatic cells (P = 0.010). In 68% of patients, some micrometastatic cells were judged to be proliferating at proportions ranging from 1 of 11 (9%) to 4 of 4 (100%). Higher Gleason score of the primary tumor was associated with a higher proliferative proportion of micrometastatic cells (P = 0.038). We conclude that, in patients with clinically localized disease, there is wide variability in the prevalence of micrometastatic cells and the proportion which are proliferating. Long-term follow-up will determine whether the development of clinically obvious metastatic disease is related to higher prevalence of micrometastatic cells in the marrow or the proportion that are proliferating.  (+info)

Oral etoposide for refractory and relapsed neuroblastoma. (8/285)

PURPOSE: To describe the efficacy of oral etoposide against resistant stage 4 neuroblastoma. PATIENTS AND METHODS: Patients with refractory or recurrent stage 4 neuroblastoma were treated with etoposide 50 mg/m(2) taken orally each day, in two or three divided doses, for 21 consecutive days. Treatment could be repeated after a 1-week period. Extent-of-disease studies included imaging with 131-iodine-metaiodobenzylguanidine and extensive bone marrow (BM) sampling. RESULTS: Oral etoposide was used in 20 children between the ages of 2 and 11 years (median, 6 years). Prior treatment included high doses of alkylating agents and a median of 4.5 cycles of etoposide-containing chemotherapy, with cumulative etoposide doses of 1,800 mg/m(2) to 3,935 mg/m(2) (median, 2,300 mg/m(2)). Oral etoposide produced antineuroblastoma effects in four of four children with disease refractory to intensive induction treatment; sampling variability could account for resolution (n = 3) or reduction (n = 1) of BM involvement, but improvement in other markers also occurred. Antineuroblastoma effects were also evident in five of five children with asymptomatic relapses after a long chemotherapy-free interval: BM disease resolved and all other disease markers significantly improved in two patients, and disease markers improved or stabilized in three patients on treatment for more than 6 months. In these nine patients, extramedullary toxicity was absent, neutropenia did not occur, transfusional support was not needed, and preliminary data suggested little immunosuppression (phytohemagglutinin responses). Oral etoposide was ineffective in all (11 of 11) patients with rapidly growing tumor masses. CONCLUSION: Given the absence of toxicity to major organs, the minimal myelosuppression or immunosuppression, and the antineoplastic activity in patients with low tumor burdens after high-dose chemotherapy, limited use of low-dose oral etoposide should be considered for inclusion in postinduction consolidative treatment programs aimed at eradicating minimal residual disease.  (+info)

INNSBRUCK, Austria-The presence of bone marrow micrometastases in women newly diagnosed with breast cancer is a highly significant predictor of poor outcome, according to a pooled analysis of data fro
The primary goal of this study was to determine whether the known antibody-dependent cytotoxicity of Edrecolomab (18) could be monitored in advanced breast cancer patients by repeating immunocytochemical bone marrow aspiration before and after antibody infusion. We were able to demonstrate that typing for EpCAM expression of micrometastatic breast cancer cells defined these cells as suitable targets of Edrecolomab, which was originally thought to be a cytotoxic agent for colorectal cancer cells only. Because extrapolation from antigen patterns expressed by the primary tumor has been shown to be unreliable (23) , phenotyping of bone marrow micrometastases by double-labeling techniques thus may help enlarge the therapeutic spectrum of monoclonal antibody therapy. On the basis of our present data, we believe that antigen expression by micrometastatic cells may be a better predictor of response to antibody-based therapy than expression by the related primary tumor. Our pilot study provides data that ...
In 1998, our group first reported isolation of HER2-positive CTCs from the peripheral blood of breast cancer patients with organ-confined tumors by means of the patented combined buoyant density gradient and immunomagnetic separation technique (10, 11). Against the background that breast cancer patients with distant metastasis at diagnosis had disseminated HER2-overexpressing epithelial cells in the bone marrow (15), the hypothesis was generated that at the time of primary treatment CTCs expressing the HER2-oncogenic receptor might be intermediates for the metastasis process. This assumption is further supported by the association between bone marrow micrometastases and the occurrence of HER2-positive cells. To the best of our knowledge, this is the first study to investigate the clinical relevance of HER2-positive CTCs in the peripheral blood of nonmetastatic breast cancer patients.. In this study, HER2-positive CTCs were present in the peripheral blood of 17 of 35 (48.6%) primary breast cancer ...

The mainstay of chemotherapy for ESFT is currently vincristine, cyclophosphamide, and doxorubicin, alternating with ifosfamide and etoposide (44) . With these drugs and adequate local control of the primary tumor, many patients with localized ESFT (excepting those with pelvic primary tumors) can be cured. However, for patients with high-risk ESFT (which includes pelvic primary sites and metastatic disease at diagnosis), the prognosis is much worse, especially for tumors with spread to bone or bone marrow (3 , 45) . Attempts to improve outcome for high-risk ESFT using intensive induction therapy followed by myeloablative chemotherapy with stem cell rescue have achieved responses, but improvement in overall survival has been disappointing due to recurrent disease, especially in patients with bone and/or bone marrow metastases at diagnosis (3 , 45, 46, 47, 48) .. One possible approach to improve therapy for metastatic ESFT could be to use intensive (myeloablative) chemoradiotherapy to maximally ...
Luekocytosis literally means abnormal increase in the Leukocytes or the white blood cells. Luekocytosis can be affirmed by if the number of leukocytes that are circulating in the peripheral blood exceeds the Normal White Blood Cell Count of 10,000 white cells per microliter.. As production and release of white blood cells is expected in cases of fighting foreign microorganisms that attempt to invade the body. Luekocytosis can also be caused by disorders in the immune system and by bone marrow tumors.. An increase in the Granulocytes (white blood cells with large granules in their cytoplasm) is noticeable during pregnancy. This increase gets more exaggerated during the labor and the first postpartum week.. Infants and newborns normally have a high count of leukocytes. This high level is very noticeable with neutrophil which drops down within 2 weeks after birth.. Luekocytosis can also be a result of heavy exercises, severe physical or emotional stress, expose to sunlight or cold.. Luekocytosis ...

Many people enjoy long and healthy lives after being successfully treated for their blood cancer. Sometimes, however, the treatment can affect a persons health for months or even years after it has finished. Some side-effects may not be evident until years after treatment has ceased. These are called late effects. Some people who have been treated with chemotherapy or radiotherapy may be at a higher risk of developing other diseases such as myelodysplastic syndrome (a bone marrow disease) and other (secondary) cancers including leukaemia and melanoma (a type of skin cancer). These cancer treatments also have been shown to increase the risk of cardiac (heart) problems, gut problems, and other organs may be affected too.. Evidence suggests that radiotherapy to the chest at a younger age may increase the chances of developing lung cancer, breast cancer or heart problems later in life. While anthrocycline-containing chemotherapy regimens, may increase the risk of developing heart problems or ...

RATIONALE: Biopsy of sentinel lymph nodes and bone marrow may improve the ability to detect and determine the extent of cancer. PURPOSE: Phase II
Introduction: Gastric cancer is the fifth most commonly diagnosed cancer and the third leading cause of cancer related death worldwide. There are two types of gastric carcinoma: intestinal, characterized by cohesive tumor cells arranged in glandular formation, and diffuse, which is poorly cohesive with crescent-shaped eccentric nuclei. The diffuse type of gastric carcinoma, including signet cell carcinoma, is common in patients less than 50 years of age and is associated with advanced disease and poor prognosis. Diffuse type of carcinoma mostly found in patients without classic risk factors for gastric carcinoma such as untreated H. Pylori, or smoking history. Signet cell carcinoma has a high rate of bone marrow metastasis, and can present with severe cytopenias. Once bone marrow metastasis is diagnosed, average life expectancy is 11 to 121 days. Though the global incidence of gastric carcinoma has declined since 1970, incidence of diffuse-type carcinoma has increased by ten-fold. Case presentation: A

Tumor cell dissemination in bone marrow or other organs is thought to represent an important step in the metastatic procedure. agents also to progress our knowledge of the biology of metastasis. Intro Breast cancers (BC) may be the most common tumor in ladies in European countries [1]. Despite medical procedures and adjuvant systemic therapy a lot of women with early BC still relapse and perish of their disease. Minimal residual disease (MRD) after possibly curative medical procedures for BC can be thought to donate to disease relapse also to be the prospective of adjuvant treatment. MRD is thought as micrometastatic cells undetectable by conventional lab and imaging testing. Surrogates of MRD are tumor cells recognized in the bone tissue marrow (disseminated tumor cells (DTCs)) and peripheral bloodstream (circulating tumor cells (CTCs)) [2]. The recognition and characterization of DTCs/CTCs are anticipated to result in customized treatment strategies and speed up the introduction of novel ...

In multiple myeloma, the tumor cells mainly reside in the bone marrow, where they bind to stromal cells and induce the secretion of cytokines. Among them, IL-6 is one of the most important factors mediating multiple myeloma cell growth, survival, and drug resistance (9, 10). The gp130 signal transducer chains of the IL-6R complex are constitutively associated with JAK kinases, which play a critical role in IL-6-mediated cellular response (11). Evidence for JAK activation in multiple myeloma cells in vivo comes from studies showing constitutive activation of STAT3 in tumor samples, whereas little or no activated STATs were detected in bone marrow from normal individuals or patients with no evidence of bone marrow metastases (30-32). Here, we show that the selective JAK inhibitor INCB20 induces cytotoxicity in multiple myeloma cells by blocking IL-6 signaling pathways.. Inhibition of cell growth by INCB20 was achieved in nine multiple myeloma cell lines; sensitivity to INCB20 treatment, however, ...

OUTLINE: This is a dose-escalation study.. Patients receive oral beta-glucan and monoclonal antibody 3F8 (MOAB 3F8) IV within 1.5 hours on days 1-5 and 8-12. Treatment repeats every 28 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.. Cohorts of 6 patients receive escalating doses of beta-glucan and MOAB 3F8 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 6 patients experience dose-limiting toxicity.. Patients are followed monthly for 6 months, every 2 months for 6 months, and then every 3-6 months for 2 years.. PROJECTED ACCRUAL: A maximum of 24 patients will be accrued for this study within 2 years. ...
There is increasing evidence that the presence of CTCs and DTCs is correlated with minimal residual disease or disease progression in patients with breast cancer. Nevertheless, the underlying molecular characteristics of micrometastatic cells associated with the development of overt metastases remain largely unknown. EMT is a multistep process that has been suggested to play a key role in cancer progression and metastasis [12]. Accordingly, CTCs bearing characteristics of an EMT phenotype should be actively involved in tumour dissemination, proliferation and metastasis. Twist is a transcription factor that, among others, participates in EMT and is upregulated in many tumour cells [18-22, 47]. In a recent report by Watson et al. [24], Twist expression was specifically enhanced in a gene signature obtained from epithelial cell adhesion molecule-enriched bone marrow samples of patients with breast cancer after neoadjuvant chemotherapy. Twist also increases VEGF expression, while it is directly ...
Bone marrow biopsy is performed to determine whether there is any functional, structural or cellular change to the bone marrow. It is a procedure that is only necessary if there is a very high suspicion of bone marrow disease; indications include pancytopenia, persistent neutropenia, monoclonal gammopathy, non-regenerative anaemia, leukocytosis, circulating atypical lymphocytes and staging for lymphoid neoplasia.. ...
and it has an unknown cause. What happens? Well, cells in the bone marrow start putting out tons of misfolded proteins. These buggers settle in the organs, like the heart, kidney, liver, and digestive tract, gradually gumming up the works and leading to the failure of the affected organ(s). They can also settle in other tissues, like the tongue, salivary glands, body fat, etc. Untreated, the disease progresses rapidly, and death usually occurs in a couple of years. The other outcome is that I was forced into retirement from my psychotherapy practice, but as you will see, it led me to another purpose.. While not strictly a cancer, amyloidosis is treated very much like its cousin multiple myeloma, another bone marrow disease. I was lucky enough that, the disease having been identified relatively early in its progression, none of my major organs had been strongly impacted. Actually, the big tip-off was my very enlarged tongue. Macroglossia, as its called, is a symptom that occurs in fewer than ...

Today more than 70 diseases are being treated using stem cells and the possibilities for these remarkable cells keep growing. Im not alone when I tell you that in the future stem cells will be used to cure and treat diseases now fatal or disabling. Stem cell discoveries in the 21st century will be like the antibiotic boom in the last century.. The reason for the explosion in stem cell research is because these cells have the remarkable ability to develop into almost any type of cell in the body. Its a complicated process, but after years of successful research, stem cells are now considered standard therapy in the treatment of many serious diseases such as leukemia, lymphoma, some bone marrow diseases like multiple myeloma and some immune system diseases. And the list is growing. ...
Deletions and dominant-negative mutations in IKZF1, the gene encoding Ikaros transcription factor, are found in ∼85% of Ph+ B-ALL and in some cases of Ph− B-ALL, and are associated with poor prognosis. Genomic studies of high-risk Ph− or Ph-like B-ALLs have revealed frequent mutation and activation of TK genes and signaling pathways. While ABL1 tyrosine kinase inhibitors (TKIs) such as dasatinib and ponatinib have been incorporated into chemotherapy regimens for Ph+ B-ALL, the majority of patients still relapse, which correlates with residual bone marrow disease following induction therapy. New therapeutic strategies are needed for patients with Ikaros-mutant, high-risk Ph+ and Ph− B-ALL.. Using mice with a conditional Ikzf1 mutation (Ike5fl) that mimics the dominant-negative Ik6 mutant found in human B-ALL, we demonstrated that loss of Ikaros DNA-binding function arrests B-lymphoid development at a large pre-B cell stage that can give rise to B-ALL. Survival and proliferation of ...

In November 2016 Schmoul was diagnosed with Systemic Mastocytosis, a rare bone marrow disease. Despite how he felt or how far he could still ride Lucy, the doctors told him that he was indeed very ill and would require chemotherapy and a stem cell replacement. As what frequently happens in life, our plan is not necessarily Gods plan. Schmoul began taking an experimental oral chemo drug, Midostaurin, in March 2017. The drug was approved by the FDA in April and Schmoul has continued on it. Unfortunately, it has not been the miracle worker we had hoped for. It appeared to decrease the Mast Cells in the bone marrow but his organs (spleen and liver) continue to grow larger. As a result, the stem cell transplant is on hold until we find a treatment that will debulk the spleen.
A new study finds that longer courses of a mild form of chemotherapy may help patients with a bone marrow disease only recently considered a form of cancer. Writing in the April 15, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society, researchers say the study found that 45 percent of patients with Myelodysplastic Syndrome (MDS) who relapse did respond to a second course of treatment, but that the quality and duration of the second response was inferior to the initial treatment, leading researchers to believe that longer initial treatments may be more beneficial to patient outcome..

Neuroblastoma is a highly malignant tumor of children that arises in the peripheral sympathetic nervous system, and spreads widely to bones and bone marrow. The survival of children with metastatic neuroblastoma is less than 40%, despite intensive chemotherapy, radiation and bone marrow transplant. Metaiodobenzylguanidine (MIBG) is a chemical similar in structure to noradrenaline and specifically taken up by neuroblastoma, thus providing a means to detect tumor metastases and to deliver intravenous tumor-targeted radiation by attaching a radioactive iodine molecule. 131I-MIBG has achieved responses of 40% in children with relapsed neuroblastoma, with very few side effects, but due to the special requirements of administering radioactive medicines, is used at only a few centers and is not yet approved for commercial use by the FDA. Furthermore, there is very little pre-clinical data on using MIBG in combination with the new molecularly targeted drugs to provide a platform for overcoming resistant ...

The protease uPA and its inhibitor PAI-1 play major roles in hemostasis and are also involved in cancer progression. This is mainly caused by their ability to degrade extracellular matrix-facilitating tumor cell migration. This study aimed to investigate the impact of uPA/PAI-1 and disseminated cytokeratin-positive cells (dCK+) on the outcome and the existence of synergistic effects. We retrospectively analyzed a cohort of 480 breast cancer cases with known uPA/PAI-1 and dCK+ status. uPA/PAI-1 was tested on fresh tumor samples using a commercial ELISA test. Bone marrow aspirates were investigated immunocytochemically for CK18. DCK+ cells were identified in 23% of cases. uPA positivity was significantly associated with the occurrence of dCK+ cells (P = 0.028). uPA and PAI-1 were significantly associated with outcome in the subgroup of early-stage cases without chemotherapy. DCK+ cells alone were not prognostic. However, we found synergistic effects. In the subgroup of node-negative cases with and without
