Survival with regional and distant metastases from cutaneous malignant melanoma. The clinical course of 312 consecutive patients after initial presentation with metastatic melanoma, 165 of whom presented with regional metastases at cutaneous or subcutaneous, or both, nodal sites and 147 with metastases at distant sites, was reviewed. The five year survival rate for regional metastases was 43.4 per cent compared with a five year survival rate for distant metastases of 4.9 per cent (p less than 0.0001). Favorable prognostic variables for survival from first regional metastases included primary melanoma sites on the extremities compared with the head, neck and trunk (p = 0.043) and a disease-free interval of more than one year from primary surgical treatment to regional metastases (p = 0.0058). Favorable prognostic variables for survival from the first distant metastasis included a disease-free interval of more than one year from primary surgical treatment to distant metastases (p = 0.0092), the type of resection of metastatic disease (p = 0.00027) and the addition of systemic immunotherapy (p = 0.0011). Forty-nine patients with totally resectable distant metastases had a five year survival rate from the treatment of the initial metastasis of 13.1 per cent, whereas 33 patients having palliative resections had a five year survival rate of 7.5 per cent. All 165 patients who did not have resection for distant metastases died within five years. The results of our experience support therapeutic efforts to ablate both regional and distant metastases of malignant melanoma when feasible.
