  Purpose

RATIONALE: Isotretinoin may prevent the development of cancer cells.

PURPOSE: Randomized double-blinded phase II trial to study the effectiveness of isotretinoin with or without vitamin E for chemoprevention of cancer in persons at high risk of developing lung cancer.

Estimated Enrollment: 60
Study Start Date: January 1993
Detailed Description:

OBJECTIVES:

  • Determine whether any intermediate endpoint biomarkers in patients at high risk for the development of lung cancer change after treatment with isotretinoin given with or without vitamin E.
  • Determine whether vitamin E can reduce the toxic effects of low-dose isotretinoin administered for 1 year in these patients.

OUTLINE: This is a randomized, double-blind study. Patients are stratified according to smoking status (smoker vs ex-smoker).

All patients undergo bronchoscopy. All observed lesions are biopsied. Patients are then randomized to one of three treatment arms.

  • Arm I: Patients receive oral isotretinoin daily.
  • Arm II: Patients receive oral isotretinoin and oral vitamin E daily.
  • Arm III: Patients undergo observation only. Treatment continues in arms I and II for 1 year in the absence of unacceptable toxicity.

Patients are followed annually for 2 years.

PROJECTED ACCRUAL: A total of 60 patients (20 per arm) will be accrued for this study within 3 years.
