Background
Chemotherapy is highly effective for metastatic germ cell tumor (GCT), but experience with resection of hepatic metastases from GCT is limited.
Methods
Fifteen patients with GCT metastatic to the liver underwent 16 hepatic operations (1975–2002). Pre-resection therapy, surgical pathology, and operative outcomes were reviewed. All patients were followed to death or last contact for survival and disease status.
Results
Patients underwent biopsy (three), wedge resection (nine), bisegmentectomy (two), and major lobectomy (two). Hepatic histology included: necrosis (33%), viable tumor (27%), mature teratoma (13%), and benign histology (27%). Concomitant resection of extrahepatic disease (14 patients, 93%) found necrosis (53%), mature teratoma (27%), and viable tumor (13%). Operative mortality was 0% and morbidity was 40%. At 8.2 years (mean) from resection, 11 patients (73%) were alive: five with no evidence of disease, two with elevated tumor marker only, and four with gross disease. Four patients (27%) died. The 10-year overall survival was 62% from diagnosis.
Conclusion
Resection of post-chemotherapy hepatic disease is safe, even when combined with resection of extrahepatic residual disease. The varied histologic findings, lack of reliable predictors, and prolonged survival achieved support a multidisciplinary approach which includes surgical resection of hepatic metastases.
