Mesothelioma Related Clinical Trials:
A Phase II Feasibility Study of Extrapleural Pneumonectomy With Intraoperative Intrathoracic/Intraperitoneal Heated Cisplatin With Amifostine and Sodium Thiosulfate

• To monitor tumor recurrence and patient survival, and compare those results to historic controls. [ Time Frame: TBD ] [ Designated as safety issue: No ]
  

• To document the morbidity and mortality of this treatment protocol in this patient population [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]
  
• to evaluate the pharmacokinetics of cisplatin. [ Time Frame: 3 years ] [ Designated as safety issue: No ]
  

Drug: Cisplatin
Heated and given as an one-hour lavage of the chest and abdomen during surgery
Drug: Sodium Thiosulfate
After the one-hour lavage, sodium thiosulfate is given intravenoulsy.

• Patients will undergo surgery called extrapleural pneumonectomy which involves removal of the lung, the lining of the lung, the covering of the heart, and the muscle that separates the chest and abdomen. At the conclusion of the resection, if the patient has less then 1 cm3 of residual gross disease in one or more areas, then the heated chemotherapy lavage will begin. If more than this volume of disease is present, then the patient will receive additional treatment off-study.
• The chemotherapy treatment consists of a one-hour lavage of the chest and abdomen cavity with heated cisplatin given in the operating room through the surgical incision. At the completion of the hour, sodium thiosulfate is given intravenously to reduce the potential side effects of cisplatin.
• During the surgery and for four hours following the completion of the cisplatin lavage, blood samples, urine samples, chest wall muscle samples, and samples of the chemotherapy solution will be done in order to measure the concentration of chemotherapy and the impact of cisplatin on the various cell samples.
• Patients will remain in the hospital until they have recovered from surgery (7-14 days). Following discharge from the hospital, patients will be seen 1-2 weeks post-operatively for blood tests. 6 weeks later additional blood tests and and echocardiogram will be performed. This echocardiogram will be repeated 6 months post-operatively to re-assess heart function.

Inclusion Criteria:

• Male of non-pregnant female 18 years of age or older

• Presence of active concomitant malignancy
• Patients with a psychiatric or addictive disorder which would preclude informed consent
• Previous chemotherapy or radiation therapy to treat mesothelioma
• Chemotherapy or radiation therapy administered within 3 years for another malignancy
