title: Improved survival after resection of pulmonary metastases from malignant melanoma.
abstract: The value of resecting pulmonary metastases from malignant melanoma was retrospectively examined. Between 1981 and 1989, 56 patients (35 men and 21 women with a mean age of 49 years) had 65 pulmonary resections for histologically proven metastatic melanoma after treatment of the primary tumor. In patients undergoing thoracotomy, 50% (28/56) had pulmonary metastases as the initial site of recurrence. Twenty-eight patients (50%) had local-regional recurrence before the development of lung metastases. Eight lobectomies, two segmentectomies, and 55 wedge excisions were done. Fifty-four patients (54/56, 96%) underwent complete resection, and there were no operative deaths. The postthoracotomy actuarial survival was 25% at 5 years (median interval, 18 months). Location of the primary tumor, histology, thickness, Clark level, local-regional lymph node metastases, or type of resection was not associated with improved survival. Patients without regional nodal metastases before thoracotomy had a median survival of 30 months compared with 16 months for all others (p = 0.04). Patients with lung as the site of first recurrence had a median survival of 30 months compared with 17 months for patients with initial local-regional recurrence (p = 0.038, log-rank test). Despite systemic spread, patients with isolated pulmonary metastases from melanoma may benefit from metastasectomy.
