A 38-year-old male with a history of non-seminomatous germ cell tumor (NSGCT) of the anterior mediastinum, previously treated with four cycles of bleomycin, etoposide, and cisplatin, presented with a 4 cm residual mediastinal mass. Tumor markers prior to surgery were alpha-fetoprotein (AFP): 6.56 ng/mL and beta-human chorionic gonadotropin (β-hCG): 0.2 mIU/mL. The authors describe a robotic technique for en bloc resection of a residual mediastinal germ cell tumor with pericardial involvement, performed with partial pericardiectomy and Dacron patch reconstruction to achieve an oncologic non-visible tumor (R0) resection.
The surgery was successful, and the postoperative chest X-ray was normal. The patient was discharged four days later. The pathology of the resected specimen revealed a residual mixed germ cell tumor, comprising 80 percent teratoma and 20 percent seminoma.
