Dacarbazine and/or Cisplatin Compared With Complete Metastasectomy in Treating Patients With Stage IV Melanoma

DISEASE CHARACTERISTICS:

• Diagnosis of metastatic melanoma

  • Solitary pulmonary nodule may not be sole site of metastatic disease
  • No disease limited to subcutaneous, cutaneous, or peripheral nodal (neck, axillary, groin, or iliac nodes) sites only
• Measurable disease
• Disease progression during or after prior interleukin-2 (IL-2)-based therapy OR ineligible for high-dose IL-2 therapy

• Metastatic disease amenable to complete surgical resection

  • Less than 5% estimated mortality from surgery
  • Prior complete metastasectomy allowed provided disease did not recur within 6 months after surgery
• No primary ocular or mucosal melanoma
• No brain metastases
