January 2nd, 2009. Phase I and Pharmacokinetic Study of Pemetrexed plus Cisplatin in Chemonaive Patients with Locally Advanced or Metastatic Malignant Pleural Mesothelioma or Non–Small Cell Lung Cancer
Conclusions: Pemetrexed with vitamin supplementation was safe and well tolerated at higher doses than the currently established 500 mg/m2 + 75 mg/m2 cisplatin. Based on this study, the recommended dose would be 800 mg/m2 pemetrexed + 75 mg/m2 cisplatin. However, recent studies showed a lack of improved efficacy for 900 or 1,000 mg/m2 single-agent pemetrexed versus 500 mg/m2 and a lack of PK/pharmacodynamic exposure-response relationship for the pemetrexed/cisplatin combination across pemetrexed exposures corresponding to this dose range. Based on currently available evidence, we recommend retaining the established dose.
December 25th, 2008. Peritoneal mesothelioma: treatment with cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy
Conclusion: Cytoreductive surgery combined with HIPEC may improve the length of survival for patients with diffuse malignant peritoneal mesothelioma; such patients should be treated in specialized centers.

December 19th, 2008. Gemcitabine combined with oxaliplatin in pretreated patients with malignant pleural mesothelioma: an observational study
Conclusion: Pemetrexed-pretreated patients with progressive MPM may benefit from a consecutive chemotherapy with oxaliplatin and gemcitabine without significant toxicity.
December 17th, 2008. Diffuse Malignant Peritoneal Mesothelioma: Failure Analysis Following Cytoreduction and Hyperthermic Intraperitoneal Chemotherapy (HIPEC)
We conclude that minimal residual disease, compared with macroscopically complete cytoreduction, correlated to failure in critical anatomical areas, suggesting the need for maximal cytoreductive surgical efforts. In selected patients, aggressive management of progressive disease seems worthwhile.

December 12th, 2008. Tumor eradication after cyclophosphamide depends on concurrent depletion of regulatory T cells: a role for cycling TNFR2-expressing effector-suppressor T cells in limiting effective chemotherapy
Indeed, we observed that the drug gemcitabine, which does not deplete cycling regulatory T cells, eradicates established tumors in mice only when CD25+ CD4+ T cells are concurrently depleted. Cyclophosphamide could be used to achieve regulatory T cell depletion in combination with chemotherapy.
December 4th, 2008. Cytoreductive surgery and continuous hyperthermic peritoneal perfusion in patients with mesothelioma and peritoneal carcinomatosis: hemodynamic, metabolic, and anesthetic considerations
0082) after completion of CHPP compared with patients with peritoneal carcinomatosis. We conclude that the transient hemodynamic and metabolic perturbations associated with cytoreductive surgery and CHPP with cisplatin can vary according to the primary diagnosis (mesothelioma versus peritoneal carcinomatosis) warranting this therapy.
December 2nd, 2008. Malignant peritoneal mesothelioma-Results from the International Expanded Access Program using pemetrexed alone or in combination with a platinum agent
Results: Response rates (95% CI) for PEM, PEM/CIS, and PEM/CARBO were 12.5% (3.5, 29.0), 20.0% (7.7, 38.6), and 24.1% (10.3, 43.5), respectively. Median survival for PEM was 10.3 months. One-year survival rates for PEM/CIS and PEM were 57.4% (95% CI: 10.3, 100) and 41.5% (95% CI: 4.6, 78.4), respectively, and were not available for PEM/CARBO. Anemia was the most common serious adverse event (6.4%). Neutropenia (34.6%) was the most frequent CTC grade 3 or 4 toxicity reported. Concluding statement: PEM with or without a platinum agent was both active and well tolerated in patients with peritoneal mesothelioma.
December 2nd, 2008. Monitoring of Chemotherapy Response in Malignant Pleural Mesothelioma Using Fluorodeoxyglucose Positron Emission Tomography
The tumor lesion exhibited shrinkage on CT and a decrease in the standardized uptake value (SUV) max after the first course of chemotherapy, but exhibited size enlargement and an increase in SUV max after the second course of chemotherapy. These findings suggest that results of quantification of metabolic response by FDG-PET are related to the objective response as determined by CT in patients with MPM.

November 26th, 2008. Mesothelioma: treatment
There are few active cytotoxic drugs in this disease. Currently, based on two randomised trials, the most efficacious chemotherapy regimen consists in a combination of cisplatin and an antifolate agent, pemetrexed or raltitrexed.

November 26th, 2008. Comparison of semiquantitative fluorescence imaging and PET tracer uptake in mesothelioma models as a monitoring system for growth and therapeutic effects
Conclusion: Fluorescence imaging could be used to semiquantitatively monitor tumor size, whereas PET could be used to monitor tumor response to therapeutic treatments, and especially, FLT might be a good marker of the response to anti-folate chemotherapeutics.

Eleven patients died, three survived with tumor, and seven survived free of tumor. CRS + HIPEC was well tolerated in our selected patients with PC, some of whom had improved survival.
November 17th, 2008. Outcomes of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for peritoneal mesothelioma: the Australian experience
Conclusion: CRS and HIPEC is a treatment option for peritoneal mesothelioma. Patients with epithelioid tumor who undergo complete cytoreduction may potentially benefit from this procedure.
November 14th, 2008. Outcomes with first-line platinum-based combination chemotherapy for malignant pleural mesothelioma: a review of practice in British Columbia
No difference is seen combining platinum analogs with gemcitabine or pemetrexed. Platinum-based doublets might represent a therapeutic ceiling for cytotoxic chemotherapy in MPM.

November 11th, 2008. Novel and existing mutations in the tyrosine kinase domain of the epidermal growth factor receptor are predictors of optimal resectability in malignant peritoneal mesothelioma
With longer follow-up, mut+ may not only be predictive of survival but may represent a subset of patients whose disease may be responsive to TK-inhibitor therapy. Experiments confirming the activating properties of the novel mutations are warranted.

November 8th, 2008. Effective chemotherapy based on a chemosensitivity test for malignant pleural mesothelioma
Numerous chemotherapeutic agents have been tested in many clinical trials, but the response rate does not exceed 20% for most of the investigated regimens. Here we report a case of MPM in which the chemotherapy based on the chemosensitivity test was very effective on palliation with stable disease for a long time.
November 5th, 2008. Cytoreductive surgery and intraperitoneal chemotherapy for peritoneal mesothelioma
Conclusions: Cytoreductive surgery combined with intraperitoneal chemotherapy appears to be the optimal treatment for selected patients with peritoneal mesothelioma. Increased familiarity with this condition's presentation and natural history, and knowledge of available treatment options, will hopefully facilitate treatment of these patients and expedite speedy referral to appropriate treatment centres.

November 5th, 2008. Treatment of malignant pleural mesothelioma with carboplatin, liposomized doxorubicin, and gemcitabine: a phase II study
Conclusion: The treatment yields good results with a high number of responses and long survival, and a low toxicity. The long survival of the epitheloid subgroup with good prognostic factors is as good as or even better than some studies on radical surgery or multimodal treatment, underlining the need of randomized studies to evaluate such treatment options.
