Standard Therapy With or Without Surgery and Mitomycin C in Treating Patients With Advanced Limited Peritoneal Dissemination of Colon Cancer

Study Overview
=================
Brief Summary
-----------------
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Heating mitomycin C to several degrees above normal body temperature and infusing it into the area around the tumor may kill more tumor cells. Giving mitomycin C after surgery may kill any remaining tumor cells. It is not yet known whether standard therapy is more effective with or without surgery followed by mitomycin C. PURPOSE: This randomized phase III trial is studying standard therapy with or without surgery and mitomycin C in treating patients with advanced limited peritoneal dissemination of colon cancer

Detailed Description
-----------------
OBJECTIVES: Primary To compare the overall survival (OS) of patients with advanced limited peritoneal dissemination of colon adenocarcinoma treated with systemic therapy with vs without cytoreduction surgery and hyperthermic intraperitoneal mitomycin C. To compare the relative OS at 1 year of patients treated with these regimens. Secondary To compare the progression-free survival (PFS) of patients treated with these regimens. To compare the relative PFS at 1 year of patients treated with these regimens. To compare the quality of life of patients treated with these regimens. To compare the toxicity burden of these regimens in these patients. To compare the OS and PFS according to patients' peritoneal surface tumor genotype for the NAD(P)H (quinone oxidoreductase 1 [NQO1] 609C >T polymorphism [wild type vs heterozygous/homozygous mutant]) in patients treated with these regimens. To compare circulating tumor cells in patients treated with these regimens. OUTLINE: This is a multicenter study. Patients are stratified according to presentation (synchronous vs metachronous carcinomatosis), ECOG performance status (0 vs 1), disease volume (measurable vs non-measurable), prior first-line therapy for advanced disease (chemo-naïve vs prior first-line therapy), planned chemotherapy (oxaliplatin vs irinotecan vs fluorouracil/leucovorin calcium vs capecitabine), and planned biologic therapy (bevacizumab vs cetuximab vs none). Patients are randomized to 1 of 2 treatment arms. Arm I: Patients receive standard systemic therapy, at the discretion of patients' oncologist, comprising combinations of fluorouracil, leucovorin calcium, irinotecan hydrochloride, oxaliplatin, and/or capecitabine (including FOLFOX4, mFOLFOX6, CapeOx, or FOLFIRI) with or without bevacizumab (beginning 4-6 weeks after major surgery) or cetuximab*. Treatment repeats in the absence of disease progression or unacceptable toxicity. Patients with progressive disease may crossover to arm II. NOTE: *For patients with KRAS wild-type tumors. Arm II: Patients undergo cytoreduction surgery and hyperthermic intraperitoneal mitomycin C over 45-90 minutes. Beginning 8 weeks after surgery, patients receive standard systemic therapy as in arm I. Treatment with systemic therapy repeats for 6 courses in the absence of disease progression or unacceptable toxicity. Blood and tissue samples may be collected from patients for correlative studies. Patients complete SF-36 Health Survey; Functional Assessment of Cancer Therapy-Colorectal (FACT-C); Feeling Sad, Down, or Depressed (CES-D); and a Brief Pain Inventory quality-of-life questionnaires at baseline and then periodically during study. After completion of study therapy, patients are followed up periodically for 5 years.
