    Abstract:
    OBJECTIVE: To evaluate the prognosis and therapeutic modalities of stage I nonseminomatous germ cell tumours of the testis (NSGT) with an embryonic carcinomatous component (EC). MATERIAL AND METHODS: 18 patients with stage I nonseminomatous germ cell tumour of the testis with an embryonic carcinomatous component were treated between 1987 and 1995. EC represented more than 50% of the testicular tumour mass in 15 cases. This tumour contingent constituted the only potential prognostic factor in 4 cases, but vascular or lymphatic emboli (n = 3), tumour stage > pT1 (n = 5) or absence of endodermal sinus component (n = 9) were observed in 14 cases. The first 3 patients underwent retroperitoneal lymph node dissection and the following 15 patients were submitted to surveillance (n = 4) or chemotherapy (n = 11) according to the PVB [Cisplatin, Vinblastine, Bleomycin] (n = 7) or BOE [bleomycin, Etoposide, Cisplatin] (n = 4) protocols. RESULTS: With a follow-up of 10 to 110 months (mean: 46), the survival rate is 100% and the recurrence rate is 22%. None of the patients with a local stage exceeding pT1 relapsed after chemotherapy. 2 patients in whom the EC contingent represented less than 50% of the tumour mass and who were simply watched, did not relapse. 4 relapses, detected 3 to 14 months after orchidectomy (mean: 8.5), during surveillance (n = 2) or after chemotherapy (n = 2), required surgical resection or complementary chemotherapy. They occurred in patients in whom EC represented more than 50% of the testicular lesion. The tumour of initially conservatively managed patients did not contain an endodermal sinus component (n = 2) or presented vascular emboli (n = 1). The subjects treated by chemotherapy were characterized by the presence of emboli (n = 1) or the absence of endodermal sinus component (n = 1). The course after recurrence was favourable in 3 cases and the last patient is currently receiving chemotherapy. CONCLUSION: EC is an independent risk factor whose presence justifies proposal of complementary treatment by retroperitoneal lymph node dissection or chemotherapy, possibly limited to 2 courses of BOE. Surveillance can only be considered in the case of a minority of EC in the tumour, in the absence of any associated risk factors.
