Radiation Therapy in Treating Patients With Stage II Cancer of the Vocal Cord

A RANDOMIZED STUDY OF HYPERFRACTIONATION VERSUS CONVENTIONAL FRACTIONATION IN T2 SQUAMOUS CELL CARCINOMA OF THE VOCAL CORD

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. It is not yet known which radiation therapy regimen is more effective in treating patients with stage II cancer of the vocal cord.

PURPOSE: Randomized phase III trial to compare two regimens of radiation therapy in treating patients who have stage II cancer of the vocal cord.

Study Overview

• Status: Completed
• Conditions: Head and Neck Cancer
• Intervention / Treatment: Radiation: radiation therapy

Detailed Description

OBJECTIVES:

• Compare the local response rate in patients with stage II invasive squamous cell carcinoma of the true vocal cord treated with hyperfractionation vs conventional fractionation radiotherapy.
• Compare the acute and late toxic effects of these regimens in this patient population.
• Compare the overall and disease-free survival patterns in this patient population treated with these regimens.

OUTLINE: This is a randomized study. Patients are stratified according to substage (T2a vs T2b). Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients undergo conventional radiotherapy 5 days a week for 5 weeks followed by boost radiotherapy 5 days a week for 2 weeks.
• Arm II: Patients undergo hyperfractionation radiotherapy 5 days a week for 5 weeks followed by boost radiotherapy 5 days a week for 1.6 weeks.

Patients with biopsy-proven persistent disease at least 6 weeks after completion of radiotherapy undergo salvage surgery with neck dissection (at the discretion of the surgeon).

Patients are followed at 4 weeks, every 3 months for 1 year, every 4 months for 1 year, every 6 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 240 patients will be accrued for this study within 3.2 years.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
Local Control	From randomization to date of failure (local progression) or death or last follow-up. Analysis occurs after all patients have been potentially followed for 2 years.

Secondary Outcome Measures

Outcome Measure	Time Frame
Acute Toxicity	From start of treatment to 90 days
Late Toxicity	From 91 days after start of treatment to last follow-up.
Overall Survival	From randomization to date of death or last follow-up. Analysis occurs after all patients have been potentially followed for 2 years
Disease-free Survival	From randomization to date of failure (local, regional, or distant progression, second primary tumor, or death) or last follow-up. Analysis occurs after all patients have been potentially followed for 2 years.
