OBJECTIVES:
Primary Objective:
* Compare the effect of high-dose interferon alfa-2b treatment on the relapse-free survival of patients with stage II or III resected malignant melanoma.
Secondary Objectives:
* Compare the effect of this treatment regimen on overall survival of these patients.
* Assess the toxicity of this treatment in these patients.
* Compare the effect of treatment on quality of life.
OUTLINE: This is a randomized study. Patients are stratified by pathologic lymph node status (known vs unknown),lymph node staging procedures(sentinel lymph node procedure vs. elective lymph node dissection vs. no lymphadenectomy), Breslow depth (\<= 1.0 mm vs. 1.01-2.0 mm vs. 2.01-4.0 mm vs \> 4.0 mm), ulceration of the primary lesion (yes vs. no vs. unknown), and disease stage (lymph node positive \[N1, N2a\] vs. lymph node negative \[N0\]). Patients are randomized into one of two treatment arms in a 1:1 ratio.
* Arm I (observation): Patients undergo observation for 4 weeks.
* Arm II (Interferon Alfa-2b): Patients receive high-dose interferon alfa-2b intravenously (IV) over 20 minutes daily for 5 consecutive days. Treatment repeats weekly for 4 weeks in the absence of unacceptable toxicity.
Quality of life is assessed before treatment, at day 22, every 3 months for 2 years, and then every 6 months for 3 years.
Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter until 15 years after randomization.
PROJECTED ACCRUAL: A total of 1,420 patients will be accrued for this study over 5 years.
Inclusion Criteria:
* Histologically confirmed primary melanoma of cutaneous origin
* Stage II (T3 N0 M0 1.5-4.0 mm Breslow depth)
* Clinically negative regional lymph node pathologic status unknown OR
* Histologically negative regional lymph nodes
* Stage III (T4 N0 M0)
* Greater than 4.0 mm 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 1.01-2.0 mm with ulceration, node negative
* T3a-b N0 - primary melanoma 2.01-4.0 mm with and without ulceration, node negative
* T4a-b N0 - primary melanoma \> 4.0 mm with or without ulceration, node negative
* T1a N1a-2a (microscopic) - primary melanoma of any thickness with microscopically positive lymph node (any number)
* Patients with a positive sentinel node should undergo complete lymphadenectomy of the nodal basin prior to study
* Must complete all primary therapy (wide excision with or without lymphadenectomy) and be randomized in this study within 84 days of wide excision
