November 28th, 2009. Biomarkers for malignant pleural mesothelioma: current status
Future research efforts should focus on biomarkers predictive of the efficacy and toxicity of standard chemotherapy. Translational research should be systematically incorporated into the design of clinical trials assessing new targeted agents in MPM.
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 3rd, 2008. Opposite effects of Notch-1 and Notch-2 on mesothelioma cell survival under hypoxia are exerted through the Akt pathway
The mechanism of Notch-2 toxicity to MM cells countered that of Notch-1, as it was the result of positive transcriptional regulation of PTEN and inhibition of the PI3K/Akt/mTOR signaling pathway. These results provide new insight into the role of Notch in MM and suggest that Notch pathway inhibitors may be useful in the treatment of this deadly disease.
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 27th, 2008. The Role of Podoplanin in Tumor Progression and Metastasis
Based on these data, podoplanin might be considered as an attractive therapeutic target for both LVs and tumor cells. Further studies are necessary to investigate differences in the expression of podoplanin in normal and tumor-associated lymphatics, and between the expression of podoplanin in normal non-LECs and tumor cells.
November 27th, 2008. Clinicopathologic and prognostic significance of overexpression of her-2/neu and p53 oncoproteins in gastric carcinoma using tissue microarray
Conclusion: Although, this study failed to show any prognostic effect of p53 and her-2/neu on survival rates, we may suggest that p53 overexpression may play a role in the pathogenesis of intestinal gastric adenocarcinoma. It could also demonstrate the significantly improved survival rates with adjuvant chemoradiation. Also, TMA is a useful technique for rapid identification of protein expression profiles using minimal samples from archived tissues.
November 26th, 2008. Etiology, epidemiology, biology. Occupational respiratory cancers
In contrast, the search for an occupational exposure that should be routine in all cases of lung cancer, is generally more difficult because of the number of occupational aetiological factors and the absence of criteria that allow distinction of an occupational cancer from a tobacco related one. Therefore attention should be paid to the identification of occupational exposure in order to set up primary prevention programmes to prevent exposure still present in the working environment and, on the other hand, to identify the subjects entitled to the acknowledgement of occupational disease and/or to obtain the compensation available to asbestos victims.
November 26th, 2008. Malignant pleural mesothelioma: biology and diagnosis
Despite sometimes a good sensitivity, other potential markers as osteopontin are of little interest for MPM diagnosis because of a low specificity. In conclusion, the present data do not justify the use of biology for MPM diagnosis in routine yet but rather suggest a need for a continuing evaluation of soluble mesothelin in clinical studies and the search for other potential tumor markers.
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.
November 21st, 2008. Compensator-based intensity-modulated radiation therapy for malignant pleural mesothelioma post extrapleural pneumonectomy
Not all linear accelerators can deliver large-field MLC-based IMRT, but most can deliver a maximum conformal field of 40 x 40 cm. It is possible and reasonable to deliver IMRT with compensators for fields this size with most conventional linear accelerators.
November 21st, 2008. Secretion of N-ERC/mesothelin and expression of C-ERC/mesothelin in human pancreatic ductal carcinoma
Although C-ERC/mesothelin was frequently expressed in human pancreatic ductal carcinoma, serum N-ERC/mesothelin concentration of cancer patients was equivalent to healthy controls. N-ERC/mesothelin was not useful as a serum marker of pancreatic ductal carcinoma, but because of frequent expression, C-ERC/mesothelin might be useful as a target of molecular imaging and immunotherapy.
November 21st, 2008. Laboratory investigation of hypercoagulability in cancer patients using rotation thrombelastography
In conclusions, our data demonstrates thromboelastographic signs of hypercoagulability in patients with solid tumors. ROTEM® is able to identify the contribution of fibrinogen and platelets to clot strength in this patient population.

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. Malignant mesothelioma of the tunica vaginalis of the testis without exposure to asbestos
Conclusion: In conclusion, though a rare tumor, malignant mesothelioma of the tunica vaginalis of the testis should be considered whenever a paratesticular mass lesion is seen even without a history of trauma or asbestos exposure as is highlighted in this case. Ultrasound findings are helpful and fine needle aspiration of the tumor may assist in arrival at a diagnosis. Surgical orchidectomy remains the modality of treatment.

001) expression compared to primary carcinomas. Our data show differences in LOXL messenger RNA expression as a function of anatomic site and tumor type in cancers affecting the serosal cavities.
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.

Histology revealed extensive decidualisation. To the best of our knowledge, this is the first report of ectopic decidua mimicking peritoneal tubercles.
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.
