|Official Title:||Phase II Randomized Trial of Sequentially Administered CPT-11 and Mitomycin C in Patients With Advanced Esophageal and Stomach Cancer|
- Most efficacious of two combination regimens of sequential CPT-11 and MMC in patients with advanced and previously untreated esophageal and GE junction adenocarcinomas [ Time Frame: 2001-2010 ]
- Evaluate gene expression profile of NQ01, and Topo I genes in peripheral blood mononuclear cells and tumor tissue during therapy with MMC and CPT-11 [ Time Frame: 2001-2010 ]
- Evaluate the frequency of NQ01 gene mutations in patients with esophageal and GE junction adenocarcinomas and its association to prognosis and antitumor activity. [ Time Frame: 2001-2010 ]
- Evaluate if pre- and/or post-treatment Topo I-, CE and NQ01-gene expression in fresh tumor specimens and adjacent tissue, are associated with antitumor efficacy or toxicity. [ Time Frame: 2001-2010 ]

Rationale: Previous studies suggest that both irinotecan and Mytomycin C when administered alone have some efficacy against stomach cancer. Based on laboratory testing, researchers hypothesized that Mytomycin C may enhance the efficacy of irinotecan through an enzyme called Topoisomerase I. In addition, because Mytomycin C has severe side effects, combining these chemotherapy agents together may allow for lower dosages resulting in greater efficacy and reduced side effects. A recent study indicates that the combination of these drugs has promising anti-tumor activity against esophageal and stomach cancers. The current study builds on previous research to explore the most effective schedule for administering these drugs together.
Purpose: This study is evaluating the combination of irinotecan and Mytomycin C on two different treatment schedules in patients with advanced esophageal and stomach cancers. Characteristics of different genes will also be measured, along with genetic and molecular changes by comparing test results from the beginning and end of the study.
Treatment: Patients in this study will receive irinotecan and Mytomycin C in one of two treatment schedules. Both drugs will be administered in patients through an intravenous infusion. A computer will randomly assign patients to a treatment group. Group one will receive Mytomycin C on day 1 and irinotecan on days 2 and 9. Group two will receive Mytomycin C on days 1 and 8 and irinotecan on days 2 and 9. After day 9, patients in both groups will not be given any study drugs for almost three weeks to complete a four week cycle. Several tests and exams will be given throughout the study to closely monitor patients. Patients will continue receiving the study drugs until they experience disease growth or unacceptable side effects.
