Surgical salvage therapy for malignant intrathoracic metastases from nonseminomatous germ cell cancer of testicular origin: analysis of a single-institution experience.

BACKGROUND: Cisplatin-based chemotherapy followed by surgical extirpation of residual benign disease represents the usual sequence of curative therapy for metastatic nonseminomatous germ cell cancer of testicular origin. Occasionally, residual disease is malignant in the form of either a persistent nonseminomatous germ cell cancer tumor or degeneration into non-germ cell cancer. We reviewed our institution's experience with patients undergoing salvage operations to remove malignant intrathoracic metastases. METHODS: From 1981 through 2001, 438 patients with nonseminomatous germ cell cancer had operations to remove residual intrathoracic disease after cisplatin-based chemotherapy at Indiana University Hospital. A subset of 134 patients who underwent 186 surgical procedures to remove malignant metastases is the basis of this review. Fifty-nine patients had removal of pulmonary metastases, 49 had removal of mediastinal metastases, and 26 had removal of both pulmonary and mediastinal metastases. Surgical pathology demonstrated 84 patients with persistent nonseminomatous germ cell cancer tumors, 38 with degeneration into non-germ cell cancer, and 12 with both malignant pathologic categories. RESULTS: There were 4 (3.7%) operative deaths. The overall median survival was 5.6 years, with 55 (42.3%) patients alive and well after a mean follow-up of 5.1 years. Seventeen variables were analyzed by using Cox regression. Of these, older age, pulmonary metastases (vs mediastinal metastases), and 4 or more (vs 1) total intrathoracic metastases were significantly (P < or = .01) predictive of inferior long-term survival. CONCLUSIONS: Salvage thoracic surgery to remove malignant metastases from nonseminomatous germ cell cancer tumors of testicular origin can result in long-term survival in select patients. We identified variables that influence survival in this subset.

Short- and long-term outcomes after large pulmonary resection for germ cell tumors after bleomycin-combination chemotherapy.

BACKGROUND: Treatment of nonseminomatous germ cell tumors frequently requires bleomycin-combination chemotherapy followed by resection of residual disease. Bleomycin administration however raises concerns with respect to postoperative respiratory complications, particularly for patients undergoing large pulmonary resections. We undertook an institutional review to determine the outcome of large pulmonary resections after bleomycin-combination chemotherapy. METHODS: Between 1981 and 2001, 530 patients presented to our institution for resection of residual intrathoracic disease for either metastatic testicular or primary mediastinal nonseminomatous germ cell tumors. We subsequently reviewed 32 of these patients who required pneumonectomy (n = 19; RIGHT = 9, LEFT = 10) or bilobectomy (n = 13) after bleomycin-combination chemotherapy. RESULTS: There were four operative deaths (13%). All postoperative deaths occurred in patients undergoing right-sided resections (pneumonectomy, n = 2; bilobectomy, n = 2) as a consequence of pulmonary complications. Operative survivors had a pulmonary morbidity of 18%. Fourteen of 20 long-term survivors were found to have a satisfactory performance status at follow-up. CONCLUSIONS: Otherwise young and healthy male nonseminomatous germ cell tumors patients requiring large pulmonary resections after bleomycin-combination chemotherapy appear to be at higher than anticipated risk for pulmonary-related morbidity and mortality. However long-term survivors report an acceptable functional status.
