Participant gender:
All
Summary
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of isotretinoin may be an effective way to prevent cancer or stop cancer from growing. Interferon alfa may interfere with the growth of cancer cells. Combining isotretinoin and interferon may be an effective treatment for some recurrent cancers. PURPOSE: Phase II trial to study the effectiveness of interferon alfa plus isotretinoin in treating patients with recurrent cancer.

standard local modalities for local disease and/or effective systemic therapy for
metastatic disease, or for which other forms of systemic therapy have been refused Eligible
sites include but are not limited to: Uterine cervix Head and neck Skin Esophagus Lung
Penis Measurable or evaluable disease required Measurable disease defined as previously
unirradiated disease reproducibly measurable in 2 dimensions by physical exam, x-ray, CT,
MRI, or other radiologic procedure Documented progressive disease in a previously
irradiated site is accepted as measurable Evaluable disease includes: Any visible
radiologic disease not measurable in 2 perpendicular diameters Elevated squamous cell
carcinoma antigen (SCCA) No active brain metastases Previously treated brain metastases
that have responded to therapy do not exclude, but CNS disease is not considered measurable
or evaluable
