The ISET (Isolation by Size of Epithelial Tumor Cells) and the CellSearch Methods in Malignant Pleural...
Pleural NeoplasmsMesothelioma4 moreMalignant pleural mesothelioma (MPM) has a growing incidence and in spite of early diagnostic, their outcome remains dismal. The evolution of MPM is often local with rare distant metastases. There is now a sizable body of evidence that metastases could develop from circulating tumor cells (CTC) spread in blood before or during surgery. Thus, sensitive and specific detection of CTC in blood is considered as a potentially relevant predictive biomarker for patients with carcinomas. In exchange, the prognostic value of CTC in MPM has not yet been evaluated. Indeed, the main goal for preoperative detection of CTC is to identify patients with high risk of recurrence after surgery, in order to perform more adapted therapeutic strategy. Despite several studies reported about CTC detection, methodological aspects concerning sensitivity, specificity and reproducibility have prevented a clear appraisal of their clinical impact. Thus, the aim of our study is to evaluate the presence and the prognostic value of CTC in MPM by a double approach. In our setting, cytopathological analysis of circulating non hematological cells (CNHC), of epithelial origin, isolated according to their size (ISET, Isolation by Size of Epithelial Tumor cells) along with immunomagnetic selection, identification and enumeration of circulating epithelial cells in peripheral blood (CellSearch method) is considered a promising approach.
Four Versus Six Cycles of Pemetrexed/Platinum for MPM
Malignant Pleural MesotheliomaThe prognosis of mesothelioma is generally poor. The median survival of patients with unresectable malignant mesothelioma ranges approximately between 6-12 months. Survival is poor because there is no curative treatment. Treatment options include surgery, chemotherapy and radiotherapy. Recently multimodality treatment regimens have been reported to prolong survival. Other new therapeutic approaches include immunotherapy, gene therapy, hyperthermic chemoperfusion of the pleura and photodynamic therapy, but the results have not yet been completely validated. Even with the introduction of this new therapeutic protocol, the response does not exceed 41%, with a mean survival of 12 months. The current standard of care for unresectable malignant pleural mesothelioma is pemetrexed/cisplatin. This regimen was compared to cisplatin alone in a study including 448 patients from 19 countries which was the largest trial to date among patients suffering from malignant mesothelioma. Results showed statistically significant increase in overall survival by about 30 % (12.1 months for pemetrexed /cisplatin versus 9.3 months for cisplatin alone. In addition, there was an improvement in lung function (forced vital capacity) in the pemetrexed /cisplatin arm in comparison to the cisplatin arm. Until now, however, there is no consensus on the number of cycles of pemetrexed/cisplatin in malignant mesothelioma and there are no approved predictive markers for response. Pemetrexed/cisplatin regimen is an expensive regimen and associated with considerable toxicity and so we need to rationalize its use in our Egyptian patients. Therefore, the investigators aim in this work to compare 4 cycles versus 6 cycles of pemetrexed/cisplatin in malignant mesothelioma and to identify a predictive marker for response.
Tissue Procurement for Gastric Cancer, Gastrointestinal Stromal Tumors (GIST), Esophageal Cancer,...
Gastric CancersThe purpose of this study is to collect and store normal and malignant tissue from patients with gastric cancer, GIST, esophageal cancer, pancreas cancer, hepatocellular cancer, biliary cancer, neuroendocrine, peritoneal mesothelioma, anal cancer and colorectal cancer, an estimated 50 to 100 of each tumor type. To collect and store blood samples from patients with gastric cancer, GIST, esophageal cancer, pancreas cancer, hepatocellular cancer, biliary cancer, neuroendocrine, peritoneal mesothelioma, anal cancer and colorectal cancer. To create a database for the collected tissue and allow access to relevant clinical information for current and future protocols. To create tissue microarrays for each gastrointestinal cancer subtype, namely, gastric cancer, GIST, esophageal cancer, pancreas cancer, hepatocellular cancer, biliary cancer, neuroendocrine, peritoneal mesothelioma, anal cancer and colorectal cancer, to facilitate future molecular studies. To grant access to Dr Kindler, Dr. Salgia, and Dr. Catenacci to this database (as it is being acquired) of the coupled patient tissue samples (normal and malignant) and relevant clinical information for the investigation of tyrosine kinases, such as Met and Ron, receptor tyrosine kinase family members, STATs, paxillin, focal adhesion proteins, cell motility/migration proteins, tyrosine/serine/threonine kinase family members, related molecules, and downstream targets implicated in the pathogenesis of GI cancers. Examples of molecular testing include evaluation of DNA mutation, alternative splice variants, protein expression and phosphorylation, and immunohistochemistry on samples. These studies will be correlated with clinical information as stated above.
Alvopem® (Pemetrexed) Safety Assessment
Non Small Cell Lung CancerMalignant Pleural MesotheliomaThe present study was a phase IV, post-marketing, observational study for safety evaluation of Alvopem® use in Iranian patients with non-small cell lung cancer and malignant pleural mesothelioma. No control groups were included in the study design. The primary objective of this study was safety assessment, including the incidence of AEs.
Serum Biomarkers in Diagnosis of Mesothelioma
MesotheliomaIn this study, the investigators analyzed the efficiencies of hyaluronan, osteopontin, C-ERC/mesothelin, N-ERC/mesothelin and syndecan-1 serum levels, both individually and in combination, in distinguishing malignant pleural mesothelioma patients from patients with metastatic malignant pleural diseases, benign pleural diseases, and benign asbestos pleurisy.
Psychosocial Needs and Exploration of Online Support for Patients With Mesothelioma
MesotheliomaThe aim of this study is to learn about how mesothelioma affects patients' emotional and physical well-being. Also, the investigators would like to learn more about what patients need and how they deal with this illness. This information can help us find ways to lessen physical and emotional strains. Part of the study tests an alternate way of giving emotional support through the Internet. By providing support online, patients can participate in the comfort of their home.
Influence of Psychosocial Distress and Lifetime Trauma Exposure on Traumatic Stress Among Oncology...
LymphomaMesothelioma2 moreBackground: A cancer diagnosis is a threat to life and bodily integrity. This can cause people with cancer to experience traumatic stress. Researchers want to better understand the types of stress and emotional reactions people with cancer experience. They also want to know if the stress people with cancer have had during their life affects their stress related to cancer. Objective: To see if lifetime traumas, along with psychosocial distress, can predict traumatic stress symptoms in people with cancer. Eligibility: People ages 18 and older who have had or are currently getting care from the NIH Clinical Center for one of these cancers: Leukemia Lymphoma Mesothelioma Prostate cancer Design: Participants will be screened with name, date of birth, and diagnosis. Participants will allow access to their medical records. Participants will complete, online or in person, a demographic sheet and 3 questionnaires: The PTSD Checklist for DSM-5: This assesses traumatic stress symptoms and takes 5 10 minutes to complete. The Life Events Checklist for DSM-5: This assesses potentially traumatic life events and takes about 5 minutes to complete. The Brief Symptoms Inventory 18: This assesses psychosocial distress and takes about 4 minutes to complete....

Thrombin Generation and Platelet Activation in CRS/HIPEC
Mesothelioma; PeritoneumPseudomyxoma Peritonei1 moreCytoreductive surgery (CRS) with hyperthermic intraperitoneal peroperative chemotherapy (HIPEC), indicated for patients with peritoneal metastases from digestive or gynecological malignancies alike, demonstrates a considerable impact on hemostatic metabolism, both on platelet and on coagulation level. The potential hemostatic interference in CRS and HIPEC is phase dependent. This study demonstrates the combined use of ROTEM (rotational thromboelastometry), PACT (platelet activation test) and CAT (thrombin generation test) assays during CRS and HIPEC with a follow-up of 7 days postoperative.
