combination chemotherapy and radiation therapy in treating patients with cancer of the esophagus

Conditions: Esophageal Cancer

Summary: rationale: drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. radiation therapy uses high-energy x-rays to damage tumor cells. combining radiation therapy with chemotherapy may kill more tumor cells. purpose: phase i trial to study the effectiveness of combination chemotherapy and radiation therapy in treating patients with cancer of the esophagus.

objectives: i. estimate the maximum tolerated dose and recommend a phase ii dose for paclitaxel (tax) when administered as a 96-hour intravenous infusion with a weekly fixed dose of intravenous cisplatin (cddp) during concurrent radiotherapy for patients with localized esophageal cancer. ii. estimate the response rate of patients treated with 2 courses of tax/cddp induction chemotherapy and the complete response rate of patients treated with tax/cddp and concurrent radiotherapy. iii. describe the toxic effects of tax/cddp prior to and during radiotherapy. iv. describe the pharmacokinetics of tax as a continuous infusion (ci) over 96 hours. v. evaluate, by flow cytometry, the ability of ci tax to block esophageal cancer cells in the g2-m phase of the cell cycle. outline: after the mtd of tax is reached on part a, new patients are entered on part b. the following acronyms are used: cddp cisplatin, nsc-119875 ebrt external-beam radiotherapy tax paclitaxel (bristol-myers), nsc-125973 part a: radiotherapy plus 2-drug combination chemotherapy. ebrt using megavoltage equipment (\>/= 10 mv recommended; electron boost allowed for subclavicular fossae); plus tax/cddp. part b: 2-drug combination induction chemotherapy followed by radiotherapy plus 2-drug combination chemotherapy. tax/cddp; followed by ebrt as in part a; plus tax/cddp. projected accrual: at least 3 patients/dose will be entered on part a (up to 24 patients) and 3-6 patients on part b.
