This randomized phase III trial is studying high dose interferon alfa to see how well it works compared to observation only in treating patients with stage II or stage III melanoma that has been completely removed by surgery.

Interferon alfa may interfere with growth of cancer cells. It is not yet known whether treatment with interferon alfa is more effective than observation alone for stage II or stage III melanoma that has been completely removed surgically.

Inclusion Criteria:

• Histologically confirmed primary melanoma of cutaneous origin
• Stage II (T3 N0 M0 1.5-4.0mm Breslow depth
• Clinically negative regional lymph node pathologic status unkown OR
• Histologically negative regional lymph nodes
• Stage III (T4 N0 M0)
• Greater than 4.0mm Breslow depth OR
• Stage III (T1-4 N1)
• One lymph node positive microscopically
• Patients must meet at least 1 of the following criteria
• T2b N0 primary melanoma 1.01-2.0mm with ulceration, node negative
• T3a-b N0 primary melanoma 2.01-4.0mm with and without ulceration, node negative
• T4a-b N0 primary melanoma > 4.0mm with and without ulceration, node negative
• T1aN1a-2a (microscopic)-primary melanoma of any thickness with microscopically positive lymph node (any number)
• Note EORTC patients who are node negative T2 or T3 are ineligible
