The prognosis of patients with relapsed or refractory mediastinal germ cell tumors is uniformly poor. There have been no reports of long-term disease-free survivors using any currently available salvage regimen. We describe a patient with primary mediastinal non-seminomatous germ cell tumor refractory to initial and salvage chemotherapy, who entered his first complete remission after surgical resection and tandem autologous bone marrow transplantation. The patient remains without evidence of disease 19 months after the first BMT.

Twenty-one patients with relapsed or refractory germ cell tumors were treated with high-dose chemotherapy and marrow transplantation (HDC/BMT) from 1982-1993. Primary sites of disease were testis (17), ovary (three), and pineal gland (one). Pathology included dysgerminoma (one), choriocarcinoma with adenocarcinoma (one), seminoma (four), and nonseminoma or mixed germ cell tumor (15). Nineteen had at least two prior chemotherapy regimens and eight had cisplatin-refractory disease defined as progression within 4 weeks of a cycle of cisplatin-based chemotherapy. HDC regimens were mostly combinations of cyclophosphamide with etoposide and cisplatin or carboplatin. There were only two treatment-related deaths (aspergillosis and interstitial pneumonitis). Times to engraftment of granulocytes (21+/-8.3 days) and platelets (32+/-20.2 days) were reasonable with only the last nine patients receiving growth factors. At a minimum of 4 years follow-up, eight patients have died of disease, six of whom were cisplatin-refractory prior to transplant. Eleven patients (52% overall) are alive and continuously free of disease after 4-10 years including one of three with refractory ovarian germ cell tumor. HDC/BMT provides significant long-term disease-free survival as salvage therapy for both male and female relapsed germ cell tumor patients who are not refractory to cisplatin.
