Abstract:
We reviewed 13 patients with testicular embryonal carcinoma from July 1982 to May 1994. Embryonal carcinoma accounted for about 25% of total testicular tumors(13/56) and about 34% of nonseminomatous germ cell tumors(13/38). Among the patients with embryonal carcinoma, about 85% were diagnosed in the 15-to-34 year age group. About seventy percent of the patients had metastatic disease at the time of diagnosis and 66.7% of these had distant metastasis including by lung, bone, retroperitoneal lymph node and cervical lymph node, attesting to the aggressiveness of embryonal carcinoma and its tendency to early hematogenous spread. Serum AFP was elevated in 10 patients(76.9%) and hCG in 6 patients(46.2%). All patients with stage I (4/13) were treated with radical orchiectomy only, and all patients with stage II(3/13) were treated with radical orchiectomy and retroperitoneal lymph node dissection(RPLND) followed by chemotherapy. Of the patients with stage III(6/13), 4 patients were treated with radical orchiectomy and chemotherapy, and 2 patients with radical orchiectomy and early chemotherapy, followed by RPLND. The pathologic findings of lymph node at the time of RPLND in stage III were 1 residual embryonal carcinoma and 1 fibrosis. In stage I and II, all patients were still alive. In stage III, 2 patients were still alive for 22 and 48 months. Among the 4 expired patients, 2 were from lung metastasis and the others from sepsis might caused by chemotherapy. These results suggest that the radical orchiectomy only with close clinical observation for stage l had a good survival, and long term survival in stage II patients treated with radical orchiectomy and RPLND followed by chemotherapy will be expected. And in stage III, if the side effects of the chemotherapy is reduced, the better survival may be obtained.
