The long‐term outcome of patients who relapse after chemotherapy for non‐seminomatous germ cell tumours

OBJECTIVE: To examine the long-term survival of a group of patients with non-seminomatous germ cell tumours, who relapse after chemotherapy and are retreated with a cisplatin and etoposide-based regimen. PATIENTS AND METHODS: At the Charing Cross Hospital between 1979 and 1988 38 patients in relapse were seen. The median interval after primary therapy was 8 months. They were treated with an intensive cisplatin and etoposide-based regimen with cycles repeated at 7-10 day intervals, and with surgery in 22 patients. RESULTS: Forty-seven per cent of patients entered a second complete remission and 88% of these remain disease free. The overall survival was 46% with a median follow-up of more than 4.3 years. Surgery was performed in 14 of 18 patients who entered a second complete remission. Adverse risk factors before initial chemotherapy and the time to relapse did not predict outcome but patients with unresectable radiological masses after relapse therapy had a poor outcome despite normalization of serum tumour markers. The tumours of 68% of patients initially treated with cisplatin-based regimens and 62% of patients who also received etoposide remained responsive to conventional doses of these drugs at relapse. CONCLUSIONS: This study demonstrates that there is a group of patients with relapsed teratoma who can be cured without the need for very high dose chemotherapy and autologous bone marrow rescue.
