A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.

L-[1-11C]-tyrosine PET to evaluate response to hyperthermic isolated limb perfusion for locally advanced soft-tissue sarcoma and skin cancer. (1/241)

PET with L-[1-11C]-tyrosine (TYR) was investigated in patients undergoing hyperthermic isolated limb perfusion (HILP) with recombinant tumor necrosis factor alpha (rTNF-alpha) and melphalan for locally advanced soft-tissue sarcoma and skin cancer of the lower limb. METHODS: Seventeen patients (5 women, 12 men; age range 24-75 y; mean age 52 y) were studied. TYR PET studies were performed before HILP and 2 and 8 wk afterwards. The protein synthesis rates (PSRs) in nanomoles per milliliter per minute were calculated. After final PET studies, tumors were resected and pathologically examined. Patients with pathologically complete responses (pCR) showed no viable tumors after treatment. Those with pathologically partial responses (pPR) showed various amounts of viable tumors in the resected tumor specimens. RESULTS: Six patients (35%) showed a pCR and 11 patients (65%) showed a pPR. All tumors were depicted as hot spots on PET studies before HILP. The PSR in the pCR group at 2 and 8 wk after perfusion had decreased significantly (P < 0.05) in comparison to the PSR before HILP. A significant difference was found in PSR between the pCR and pPR groups at 2 and at 8 wk (P < 0.05). Median PSR in nonviable tumor tissue was 0.62 and ranged from 0.22 to 0.91. With a threshold PSR of 0.91, sensitivity and specificity of TYR PET were 82% and 100%, respectively. The predictive value of a PSR > 0.91 for having viable tumor after HILP was 100%, whereas the predictive value of a PSR < or = 0.91 for having nonviable tumor tissue after HILP was 75%. The 2 patients in the pPR groups with a PSR < 0.91 showed microscopic islets of tumor cells surrounded by extensive necrosis on pathological examination. CONCLUSION: Based on the calculated PSR after HILP, TYR PET gave a good indication of the pathological outcome. Inflammatory tissue after treatment did not interfere with viable tumor on the images, suggesting that it may be worthwhile to pursue TYR PET in other therapy evaluation settings.  (+info)

In vivo isolated kidney perfusion with tumour necrosis factor alpha (TNF-alpha) in tumour-bearing rats. (2/241)

Isolated perfusion of the extremities with high-dose tumour necrosis factor alpha (TNF-alpha) plus melphalan leads to dramatic tumour response in patients with irresectable soft tissue sarcoma or multiple melanoma in transit metastases. We developed in vivo isolated organ perfusion models to determine whether similar tumour responses in solid organ tumours can be obtained with this regimen. Here, we describe the technique of isolated kidney perfusion. We studied the feasibility of a perfusion with TNF-alpha and assessed its anti-tumour effects in tumour models differing in tumour vasculature. The maximal tolerated dose (MTD) proved to be only 1 microg TNF-alpha. Higher doses appeared to induce renal failure and a secondary cytokine release with fatal respiratory and septic shock-like symptoms. In vitro, the combination of TNF-alpha and melphalan did not result in a synergistic growth-inhibiting effect on CC 531 colon adenocarcinoma cells, whereas an additive effect was observed on osteosarcoma ROS-1 cells. In vivo isolated kidney perfusion, with TNF-alpha alone or in combination with melphalan, did not result in a significant anti-tumour response in either tumour model in a subrenal capsule assay. We conclude that, because of the susceptibility of the kidney to perfusion with TNF-alpha, the minimal threshold concentration of TNF-alpha to exert its anti-tumour effects was not reached. The applicability of TNF-alpha in isolated kidney perfusion for human tumours seems, therefore, questionable.  (+info)

Metabolism of [14C]phenol in the isolated perfused mouse liver. (3/241)

A previous report from this laboratory focused on the metabolism of [14C]benzene (BZ) in the isolated, perfused, mouse liver (C. C. Hedli, et al., 1997, Toxicol. Appl. Pharmacol. 146, 60-68). Whereas administration of BZ to mice results in bone marrow depression (R. Snyder et al., 1993, Res. Commun. Chem. Pathol. Pharmacol. 20, 191-194), administration of phenol (P), the major metabolite of BZ, does not. It was, therefore, of interest to determine whether the metabolic fate of P produced during BZ metabolism differed from that of P metabolized in the absence of BZ. Mouse livers were perfused with a solution of [14C]P in both the orthograde (portal vein to central vein) and retrograde (central vein to portal vein) direction to investigate the metabolic zonation of enzymes involved in P hydroxylation and conjugation. Perfusate samples were collected, separated by HPLC, and tested for radioactivity. Unconjugated metabolites were identified by comparing their retention times with nonradiolabeled standards, which were detected by UV absorption. Conjugated metabolites were identified and collected on the basis of radiochromatogram results, hydrolyzed enzymatically, and identified by co-chromatography with unlabeled BZ metabolites. The objective was to compare and quantify the metabolites formed during the perfusion of P in the orthograde and retrograde directions and to compare the orthograde P-perfusion results with the orthograde BZ results reported previously. Regardless of the direction of P perfusion, the major compounds released from the liver were P. phenylgucuronide, phenylsulfate, hydroquinone (HQ), and HQ glucuronide. A comparison of the results of perfusing P in the orthograde versus the retrograde direction showed that more P was recovered unchanged and more HQ was formed during retrograde perfusion. The results suggest that enzymes involved in P hydroxylation are generally closer to the central vein than those involved in conjugation, and that during retrograde perfusion, P metabolism may be limited by the sub-optimal conditions of perfusion. Comparison of the orthograde perfusion studies of P and BZ revealed that a larger percentage of the radioactivity released from the liver was identified as unconjugated HQ after BZ perfusion than after P perfusion. In addition, the amount of radioactivity covalently bound to liver macromolecules was measured after each perfusion and determined to be proportional to the amount of HQ and HQG detected in the perfusate samples.  (+info)

Prerequisites for effective isolated limb perfusion using tumour necrosis factor alpha and melphalan in rats. (4/241)

An isolated limb perfusion (ILP) model using soft tissue sarcoma-bearing rats was used to study prerequisites for an effective ILP, such as oxygenation of the perfusate, temperature of the limb, duration of the perfusion and concentration of tumour necrosis factor (TNF). Combination of 50 microg TNF and 40 microg melphalan demonstrated synergistic activity leading to a partial and complete response rate of 71%. In comparison to oxygenated ILP, hypoxia was shown to enhance anti-tumour activity of melphalan alone and TNF alone but not of their combined use. Shorter perfusion times decreased anti-tumour responses. At a temperature of 24-26 degrees C, anti-tumour effects were lost, whereas temperatures of 38-39 degrees C or 42-43 degrees C resulted in higher response rates. However, at 42-43 degrees C, local toxicity impaired limb function dramatically. Synergy between TNF and melphalan was lost at a dose of TNF below 10 microg in 5 ml perfusate. We conclude that the combination of TNF and melphalan has strong synergistic anti-tumour effects in our model, just as in the clinical setting. Hypoxia enhanced activity of melphalan and TNF alone but not the efficacy of their combined use. For an optimal ILP, minimal perfusion time of 30 min and minimal temperature of 38 degrees C was mandatory. Moreover, the dose of TNF could be lowered to 10 microg per 5 ml perfusate, which might allow the use of TNF in less leakage-free or less inert perfusion settings.  (+info)

Hyperthermic isolated limb perfusion with tumor necrosis factor-alpha and melphalan in patients with locally advanced soft tissue sarcomas: treatment response and clinical outcome related to changes in proliferation and apoptosis. (5/241)

Hyperthermic isolated limb perfusion with tumor necrosis factor-alpha and melphalan (HILP-TM) with or without IFN-gamma is a promising local treatment in patients with locally advanced extremity soft tissue sarcomas (STSs), with response rates of up to 84%. The mechanisms of the treatment response are poorly understood. Here, we determined the HILP-TM-induced changes in mitotic activity, proliferation, and apoptosis in 37 STSs; the additional effect of IFN-gamma; and the association of HILP-TM with treatment response and clinical outcome. On archival material, obtained before and 6-8 weeks after HILP-TM with (n = 15) or without (n = 22) IFN-gamma, the number of mitoses was counted, and the proliferation fraction was determined by immunohistological staining for the proliferation associated Ki-67 antigen (MIB1). Apoptosis was visualized by enzymatic detection of DNA fragmentation (terminal deoxynucleotidyl transferase-mediated nick end labeling method). Clinical and histological response, follow-up status, and survival were recorded. The number of mitoses dropped 57% and proliferation rate decreased with 40% after HILP-TM, whereas the amount of apoptosis after HILP-TM more than doubled as before HILP-TM. The addition of IFN-gamma to HILP-TM did not influence the changes in tumor parameters and did not affect treatment response. A better clinical response to HILP-TM was correlated with high mitotic activity and low amount of apoptosis in tumor samples before HILP-TM. Patients with highly proliferative STS before and after HILP-TM had a relatively poor prognosis. Furthermore, patients who developed distant metastases after HILP-TM had a relatively high number of dividing cells in the tumor remnants after treatment.  (+info)

TNF-alpha augments intratumoural concentrations of doxorubicin in TNF-alpha-based isolated limb perfusion in rat sarcoma models and enhances anti-tumour effects. (6/241)

We have shown previously that isolated limb perfusion (ILP) in sarcoma-bearing rats results in high response rates when melphalan is used in combination with tumour necrosis factor alpha (TNF-alpha). This is in line with observations in patients. Here we show that ILP with doxorubicin in combination with TNF-alpha has comparable effects in two different rat sarcoma tumour models. The addition of TNF-alpha exhibits a synergistic anti-tumour effect, resulting in regression of the tumour in 54% and 100% of the cases for the BN175-fibrosarcoma and the ROS-1 osteosarcoma respectively. The combination is shown to be mandatory for optimal tumour response. The effect of high dose TNF-alpha on the activity of cytotoxic agents in ILP is still unclear. We investigated possible modes by which TNF-alpha could modulate the activity of doxorubicin. In both tumour models increased accumulation of doxorubicin in tumour tissue was found: 3.1-fold in the BN175 and 1.8-fold in the ROS-1 sarcoma after ILP with doxorubicin combined with TNF-alpha in comparison with an ILP with doxorubicin alone. This increase in local drug concentration may explain the synergistic anti-tumour responses after ILP with the combination. In vitro TNF-alpha fails to augment drug uptake in tumour cells or to increase cytotoxicity of the drug. These findings make it unlikely that TNF-alpha directly modulates the activity of doxorubicin in vivo. As TNF-alpha by itself has no or only minimal effect on tumour growth, an increase in local concentrations of chemotherapeutic drugs might well be the main mechanism for the synergistic anti-tumour effects.  (+info)

Increased local cytostatic drug exposure by isolated hepatic perfusion: a phase I clinical and pharmacologic evaluation of treatment with high dose melphalan in patients with colorectal cancer confined to the liver. (7/241)

A phase I dose-escalation study was performed to determine whether isolated hepatic perfusion (IHP) with melphalan (L-PAM) allows exposure of the liver to much higher drug concentrations than clinically achievable after systemic administration and leads to higher tumour concentrations of L-PAM. Twenty-four patients with colorectal cancer confined to the liver were treated with L-PAM dosages escalating from 0.5 to 4.0 mg kg(-1). During all IHP procedures, leakage of perfusate was monitored. Duration of IHP was aimed at 60 min, but was shortened in eight cases as a result of leakage from the isolated circuit. From these, three patients developed WHO grade 3-4 leukopenia and two patients died due to sepsis. A reversible elevation of liver enzymes and bilirubin was seen in the majority of patients. Only one patient was treated with 4.0 mg kg(-1) L-PAM, who died 8 days after IHP as a result of multiple-organ failure. A statistically significant correlation was found between the dose of L-PAM, peak L-PAM concentrations in perfusate (R = 0.86, P< or =0.001), perfusate area under the concentration-time curve (AUC; R = 0.82, P<0.001), tumour tissue concentrations of L-PAM (R = 0.83, P = 0.011) and patient survival (R = 0.52, P = 0.02). The peak L-PAM concentration and AUC of L-PAM in perfusate at dose level 3.0 mg kg(-1) (n = 5) were respectively 35- and 13-fold higher than in the systemic circulation, and respectively 30- and 5-fold higher than reported for high dose oral L-PAM (80-157 mg m(-2)) and autologous bone marrow transplantation. Median survival after IHP (n = 21) was 19 months and the overall response rate was 29% (17 assessable patients; one complete and four partial remissions). Thus, the maximally tolerated dose of L-PAM delivered via IHP is approximately 3.0 mg kg(-1), leading to high L-PAM concentrations at the target side. Because of the complexity of this treatment modality, IHP has at present no place in routine clinical practice.  (+info)

A phase I-II study of isolated hepatic perfusion using melphalan with or without tumor necrosis factor for patients with ocular melanoma metastatic to liver. (8/241)

There are no satisfactory treatment options for patients with ocular melanoma metastatic to liver, and after liver metastases are identified, median survival is only between 2 and 7 months. Because liver metastases are the sole or life-limiting component of disease in the vast majority of patients who recur, we reasoned that complete vascular isolation and perfusion of the liver might result in clinically meaningful regression of disease. Between September 1994 and July 1999, 22 patients (13 women and 9 men; mean age, 49 years) with ocular melanoma metastatic to liver were treated with a 60-min hyperthermic isolated hepatic perfusion (IHP) using melphalan alone (1.5-2.5 mg/kg, n = 11) or with tumor necrosis factor (TNF, 1.0 mg, n = 11). Via a laparotomy, IHP inflow was via the hepatic artery alone (n = 17) or hepatic artery and portal vein (n = 5) and outflow from an isolated segment of inferior vena cava. Most patients had advanced tumor burden with a mean percentage of hepatic replacement of 25% (range, 10-75%) and a median number of metastatic nodules of 25 (range, 5 to >50). Complete vascular isolation was confirmed in all patients using a continuous intraoperative leak monitoring technique with 131I radiolabeled albumin. There was one treatment mortality (5%). The overall response rate in 21 patients was 62% including 2 radiographic complete responses (9.5%) and 11 partial responses (52%). The overall median duration of response was 9 months (range, 5-50) and was significantly longer in those treated with TNF than without (14 versus 6 months, respectively; P = 0.04). Overall median survival in 22 patients was 11 months. These data indicate that a single 60-min IHP can result in significant regression of advanced hepatic metastases from ocular melanoma. TNF appears to significantly prolong the duration of response.  (+info)

As well known, process identification is very important in process control. A Open-loop identification method is proposed in this paper. The identification object is a simulated facility with constant temperature hyperthermic perfusion treatment on bladder cancer. Open-loop step response is applied ,the process input and the resulted output response are logged, and the improved area method is adopted, from which the parameters of a first-order plus dead-time model can be estimated. Based on some PID tuning rule the closed loop experiments have been conducted. The experimental results have shown that the proposed method has good identification accuracy and is insensitive to the noise. Furthermore, the experiments of the closed loop control system have also indicated the design closed loop control system is valid.
In the largest single-institution regional therapy series reported to date, we found that although ILI is effective and well-tolerated, HILP is a more definitive way to control advanced disease.
Patients with pancreatic carcinoma generally have poor prognosis, since it is typically detected too late. Furthermore, it is located near anatomically important structures such as the bile ducts and major blood vessels, which complicates access to the tumor. At the time of diagnosis, only 10% of these tumours are still operable.. For advanced pancreatic carcinoma, chemotherapy only prolongs life expectancy in the range of 2 to 6.5 months. Patients previously treated with radiation and chemotherapy are rarely included in the studies because of their poor prognosis. As a result, very few such studies exist. One study (Author: Berlin JD et al) reports a median survival time (50%) of 6.7 months in a large group of 322 previously treated patients, and a 25% survival period of 10.5 months.. More recent studies of advanced, inoperable pancreatic carcinoma using newer agents could not demonstrate greater than 20-25% survival rate beyond one year.

The study, conducted over a 22-year period from 1994 to 2016, is the largest one to date of limb preservation using isolated limb infusion for sarcoma. Advocates for [isolated limb infusion] in these patients would argue that, with similar long-term survival data and meaningful overall response rates, patients would much prefer a treatment that preserves the affected extremity to one that does not, Dr. Mullinax said. Isolated limb infusion has historically been used primarily for melanoma of the extremities, and the use of this technique in sarcoma is a novel approach. Sarcoma is a rare type of cancer in the extremities with several different subtypes; the study patients who underwent isolated limb infusion had 17 different subtypes of sarcoma ...
Abstract Purpose: Isolated limb perfusion (ILP) with hyperthermia is an effective treatment for in-transit metastases of malignant melanoma in the extremities. Preclinical studies have shown that hyperthermia may induce an immunogenic death of tumour cells. We therefore decided to study whether ILP may induce tumour-specific immune responses in the clinical setting. Method: The number of Melan-A/Mart-1 specific CD8+ T cells, as well as other phenotypically different immune cells, was recorded in peripheral blood in 12 HLA-A2+ patients with in-transit metastases undergoing hyperthermic ILP with melphalan. Results: All patients underwent ILP without any complication and with an overall response rate of 83%. No substantial changes in the number of circulating T-cells, B-cells, NK-cells or monocytes were observed during follow-up. Four out of 12 patients showed an elevation of Melan-A+ CD8+ T-cells 4 weeks after ILP. Conclusion: We here report our preliminary observations that a small increase in ...

Percutaneous hepatic perfusion (PHP) is a minimally invasive treatment that delivers high-dose chemotherapy directly to metastatic melanoma in the liver. Unlike traditional chemotherapy, in which medications circulate throughout the entire body, PHP specifically targets the liver only, which can help reduce the side effects commonly associated with chemo. This approach allows oncologists to treat tumors with much higher doses of chemotherapy than would otherwise be possible when given systemically (through the peripheral veins).. At Moffit Cancer Center, percutaneous hepatic perfusion is offered to treat melanoma that has spread to the liver (as often occurs with ocular melanomas), and select other tumors metastatic to the liver. Prior to recommending this therapy to a patient, our oncologists and interventional radiologists will assess a number of factors, including the following, to ensure that PHP is a suitable option:. ...

PURPOSE OF REVIEW: The recent discovery of effective systemic treatments for melanoma has dramatically improved the prognosis for patients with advanced disease. As a result, the multidisciplinary management of melanoma has evolved significantly. In the past decades surgery was reserved for symptomatic palliation in patients with metastatic melanoma. Today surgical treatment of patients responding to systemic therapies has become an integral part of disease control. RECENT FINDINGS: Current efforts are focused on minimizing the morbidity of surgery (laparoscopic inguinal lymph node dissection, selective completion lymphadenectomy) as well as combining surgery with systemic therapy in novel ways (neoadjuvant targeted and/or immunotherapy, isolated limb infusion/perfusion with systemic immunotherapy ...

A recent Phase I clinical trial reported encouraging survival data with respect to the use of maximal cytoreduction combined with hyperthermic intraperitoneal chemotherapy (HIPEC) using pegylated liposomal doxorubicin (PLD)(e.g., Doxil™) to treat patients with advanced intra-abdominal, gastrointestinal and gynecological malignancies. HIPEC is used in conjunction with surgery and chemotherapy to treat patients with gastrointestinal tract…
Abstract: Advancements in medical technology coupled with a more thorough comprehension of oncologic diseases has resulted in a burgeoning number of aggressive treatment options available to cancer patients and a gradual loosening of the association between cancer and timely death. With the advent of extended life expectancies, however, the need to investigate the human and overall life impact of cancer diseases and treatments has increased dramatically (Langenhoff et al., 2001). This need to examine considerations of quality of life becomes even more essential in the context of high-risk treatments, such as cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy (CS+HIPEC), an extensive procedure offered to select candidates with peritoneal carcinomatosis from a variety of primary origins (Levine et al., 2007). A biopsychosocial model of research and clinical care (e.g. Wilson & Cleary, 1995) underscores the many levels and interrelationships of clinical, demographic, and ...
HIPEC is an aggressive, novel surgical treatment reserved for patients with peritoneal carcinomatosis. It combines extensive removal of cancers, known as surgical cytoreduction, with the intraoperative introduction of chemotherapeutic drugs into the peritoneal cavity at a temperature several degress above normal body temperature. The abdominal cavity is perfused for about 90 minutes, thereby exposing potential microscopic residual cancer cells directly to the synergistic effects of hyperthermia (heat), and cytotoxic agents.. HIPEC is resource-intensive and requires extraordinary surgical and multidisciplinary cooperation. As such, only a few centers nationwide offer patients this option. The Feist-Weiller Cancer Center is the only cancer center in Louisiana that offers HIPEC presently.. HIPEC is used to treat the following types of cancers in its advanced and recurrent stages:. ...
Aims and objectives.To study patients descriptions of their health after cytoreductive surgery (CRS) before discharge.. Background. Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) affects the patients recovery. The hospital stay is long, and it is important to study how patients experience their health postoperatively.. Design. Qualitative descriptive design.. Methods. Between January-May 2012, individual interviews were conducted with 20 patients in a university hospital in cen- tral Sweden using a semi-structured interview guide. Data were analysed using qualitative content analysis.. Results. Three themes (a process, body and mind, and support) and nine categories emerged. The surgery was described as a turning point, followed by a period of hope and thankfulness. Nevertheless, patients had difficulty taking in their positive feelings because they were overwhelmed by their bodily ailments. Despite the patients descriptions of being on an emotional roller ...

Splenectomy is an independent risk factor for poorer perioperative outcomes after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy: an analysis of 936 procedures
The imaging method called positron emission tomography (PET) using the radioactive tracer molecule 18F-FDG is a valuable way to both diagnose and track the progression of malignant peritoneal mesothelioma. Nuclear medicine researchers at a Hospital in Barcelona, Spain reviewed the diagnostic and treatment records of 60 people with malignant peritoneal mesothelioma, a form of mesothelioma that spreads on the membrane lining the walls of the abdomen. The study subjects included 34 women and 26 men with a mean age of 53. All the patients in the study had had multiple 18-F-FDG-PET scans to diagnose or track their cancer. Eleven of the studied patients had an FDG-PET scan prior to receiving treatment. In all cases, the scans showed characteristic mesothelioma disease … Continue reading Tracking Mesothelioma with FDG-PET » ...
SOUSA, Susana Marques de et al. Malignant Peritoneal Mesothelioma as a Rare Cause of Dyspeptic Complaints and Ascites: A Diagnostic Challenge. GE Port J Gastroenterol [online]. 2020, vol.27, n.3, pp.197-202. ISSN 2341-4545. Introduction: Malignant peritoneal mesothelioma (MPM) is a rare malignancy of the mesothelial cells in the peritoneum. The best-defined risk factor is asbestos exposure, but germline mutations in BAP1 also increase susceptibility to this tumor. The diagnosis of MPM is challenging since clinical manifestations are often nonspecific. Case Presentation: We describe a case of MPM in a 53-year-old former construction worker with prior asbestos exposure. The clinical presentation was a 3-month history of dyspeptic complaints. As initial workup, abdominal ultrasound and upper gastrointestinal endoscopy were performed. Chronic gastritis due to Helicobacter pylori was detected, which was promptly treated but without symptom relief. Abdominal ...

Researchers at Roswell Park Cancer Institute (RPCI) have determined that cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CS/HIPEC), a complex procedure to treat advanced abdominal cancers, can be done safely, and may be an effective therapy for select patients. Study results are published in the June issue of Cancer Medicine.
The SPRinT team sees patients with a wide spectrum of cancer types as peritoneal surface malignancies can arise from various organs. They can arise primarily from the peritoneum (e.g. mesothelioma, primary peritoneal cancer) or from the spread of a primary cancer (e.g. colorectal, appendix, stomach, ovary, hepatobiliary). Our team has extensive experience in treating these varieties of cancer from early to advanced stages. Previously regarded as fatal, peritoneal disease of all histological subtypes can now be successfully treated to achieve good outcomes for patients. Our multidisciplinary clinics offer a one-stop service for the evaluation and surgical management of these patients. In conjunction with our medical oncologists, we provide a comprehensive range of treatments for patients with peritoneal disease, including cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). The SPRinT team has been performing CRS and HIPEC since 2001 and currently, has one of the ...
The data were collected in the Medical Spectrum Twente, a large community teaching hospital in the regional capital of a foremost rural area in the eastern part of the Netherlands. It functions as a regional referral center for liver and lung surgery, but has no facilities for the treatment of peritoneal carcinomatosis with hyperthermic intraperitoneal chemotherapy (HIPEC).. The study design is a prospective observational cohort study evaluating the outcome of routine staging with abdominal CT concerning the ability to find liver metastases (LM), peritoneal carcinomatosis (PC) and T4-stage in colon cancer (LACC). All patients in our hospital who where treated for CRC from January 2007 till December 2009 were included in the analysis; all surgical patients with CRC in the study hospital were prospectively registered in a database designed for colorectal surgery, including patient characteristics, staging and surgical procedures, the clinical M stage and pathological TNM stage, post-operative ...

Cytoreductive surgery (CRS) plus hyperthermic intra-operative peritoneal chemotherapy (HIPC) for gastric peritoneal carcinomatosis (PC) is controversial, and selection criteria for this treatment modality are lacking. Thirty-two patients (F/M ratio 12/20; median (range) age 58 (32-75) years) underwent CRS + HIPC with cisplatin for PC from gastric adenocarcinoma in 2010-2014. This monocentric phase-2 nonrandomized prospective study with a power of 90% aimed to improve the 1-year overall survival (OS) rate with 40% (historical reference of 52% to 72%). Median PCI score was 8 (range 1-20), number of regions involved was 6 (range 1-11). The impact of 16 prognostic factors on survival was evaluated using univariable and multivariable Cox regression models. Follow-up was complete in all patients, and closed 2 years after patient inclusion. All patients had complete cytoreduction (CCR-0) and histopathological R0 resection. PCI |/= 12 without PC on any small bowel region with 4 or
Intraperitoneal chemotherapy is beneficial and tolerable, and physicians should present it as an option to women who have had successful cytoreductive surgery for their advanced epithelial ovarian cancer.
Group 1 - During laparotomy, after tumor removal, patients receive continuous hyperthermic peritoneal perfusion (CHPP) with the anti-cancer drug cisplatin. For CHPP, the cisplatin solution is heated and delivered to the abdomen through a catheter (plastic tube), washed through the abdomen for 90 minutes, and then drained out of the body through another catheter. At the close of surgery, a small catheter, called a Tenckhoff catheter, is left in the abdomen and brought out through the skin. Between days 7 and 12 after surgery, one dose of fluorouracil and paclitaxel chemotherapy is delivered through this catheter. The catheter is removed following complete recovery from surgery and the patient is discharged from the hospital. Four to 6 weeks after the surgery, patients have CT scans of the chest, pelvis, and abdomen, and then begin intravenous (IV, through a vein) chemotherapy with oxaliplatin, 5-fluorouracil (5-FU), and leucovorin. The chemotherapy is given in 4-week courses as follows: ...

Percutaneous hepatic perfusion (PHP) is a regionalized, minimally-invasive approach to cancer treatment currently undergoing Phase II and Phase III clinical testing. PHP treats a variety of hepatic tumors by isolating the liver and exposing the organ to high-dose chemotherapy. As demonstrated in clinical trials, patients treated by PHP can tolerate much higher doses of chemotherapeutic agents than those receiving traditional systemic chemotherapy without increased toxicities. Using a system of catheters and filters, PHP isolates the liver from the circulatory system and infuses a chemotherapeutic agent directly to the liver via the hepatic artery. The venous effluent from the liver is then filtered outside of the body and the filtered blood is returned into the jugular vein. PHP is a repeatable procedure and can be performed in an operating room or a radiology suite under local or general anesthesia. Delcath Systems Business Wire Delcath Systems, Inc.
