Clinical trial: Decitabine in Treating Patients With Unresectable Lung or Esophageal Cancer or Malignant Mesothelioma of the Pleura

Summary: RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.
  PURPOSE: Phase I trial to study the effectiveness of decitabine in treating patients who have unresectable lung or esophageal cancer or malignant mesothelioma of the pleura.

Detailed description: OBJECTIVES:
  -  Determine the pharmacokinetics, toxicity, and maximum tolerated dose of decitabine in patients with unresectable primary small cell or non-small cell lung cancer, unresectable esophageal cancer, or malignant pleural mesothelioma.
  -  Measure the expression of NY-ESO-1 in tissue samples of these patients before and after receiving this drug.
  -  Assess the serologic response to NY-ESO-1 in these patients before and after receiving this drug.
  -  Measure the expression of p16 tumor suppressor gene in these patients before and after receiving this drug.
  OUTLINE: This is a dose-escalation study for each stratification group. Patients are stratified according to number of prior therapies (2 or fewer vs 3 or more).
  Patients receive decitabine IV continuously on days 1-3. Treatment repeats every 5 weeks for 2 courses in the absence of disease progression or unacceptable toxicity. Patients with stable or responding disease after completion of the second course receive 2 additional courses.
  Cohorts of 3-6 patients receive escalating doses of decitabine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined for a particular stratum, additional patients from that stratum are treated at the MTD.
  Patients are followed for 1 month.
  PROJECTED ACCRUAL: A maximum of 72 patients (36 per stratum) will be accrued for this study.
