Official Title: Induction Chemotherapy Followed By Chemoradiation For Organ Preservation In Patients With Advanced Resectable Cancer Of The Hypopharynx And Base Of Tongue, Phase II

Brief 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 more than one chemotherapy drug with radiation therapy may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy and radiation therapy in treating patients with stage III or stage IV cancer of the hypopharynx or tongue.


Detailed Summary:

OBJECTIVES: I. Determine the complete histologic response rate (which represents the rate of organ preservation) to induction with cisplatin/fluorouracil followed by radiotherapy plus cisplatin in patients with selected stage III/IV cancer of the hypopharynx or base of the tongue. II. Evaluate the feasibility of accruing and treating patients with this regimen in a multi-institutional setting. III. Determine the overall complete response rate in these patients.

OUTLINE: This is a multicenter study. Patients are stratified according to center and tumor site (hypopharynx vs base of tongue). Base of tongue stratum closed as of November 15, 1998. Regimen A: Patients receive cisplatin IV over 90 minutes on days 1 and 22 and fluorouracil IV over 120 minutes on days 1-5 and 22-26. Patients with measurable neck nodes discontinue therapy if disease has progressed by day 22. All patients who achieve complete or partial response at day 43 proceed to regimen B. All others proceed to resection followed by radiotherapy (off study). Regimen B (begins within 3-4 weeks of start of second induction course): Patients receive cisplatin IV over 90 minutes every 3 weeks for 3 courses. Concurrently, patients receive radiotherapy 5 days a week for 5.6 weeks. Patients are reassessed at 8-12 weeks after radiotherapy. Patients who are disease free are observed. Other patients undergo surgical resection of nodes and/or primary tumor. Patients are followed every 4-6 weeks for 1 year, every 2 months for 1 year, every 4 months for 2 years, every 6 months for 1 year, then annually thereafter.

PROJECTED ACCRUAL: Up to 70 patients (35/tumor site) will be accrued for this study over 3.5 years.


Sponsor: Southwest Oncology Group

Current Primary Outcome: Complete response [ Time Frame: 23 to 27 weeks after beginning treatment ]

Complete disappearance of all measurable and evaluable disease. No new lesions, No disease related symptoms. No evidence of non-evaluable disease, including normalization of markers and other abnormal lab values. Specifically, the rate of organ preservation (no surgery required at the primary tumor site).
