Abstract:
OBJECTIVE:To evaluate the oncologic outcomes of patients with retroperitoneal teratoma only at primary retroperitoneal lymph node dissection (RPLND) who did not receive adjuvant chemotherapy. MATERIALS AND METHODS:Between 1979 and 2010, 23 patients with clinical stage (CS) I and II disease underwent primary RPLND at our institution with teratoma only in the retroperitoneum. No patient received adjuvant chemotherapy and the minimum follow-up was 2 years. RESULTS:At the initial diagnosis, 13 patients (56.5%) had CS I disease and 10 patients (43.5%) had CS II disease. Pathologic staging demonstrated IIA in 13 patients (56.5%), IIB in 8 patients (34.8%), and IIC in 2 patients (8.7%). The 5-year disease-free survival (DFS) was 100% with a median follow-up of 5.8 years (range, 2.1-25.4). DFS was not significantly different comparing pathologic stage IIA vs IIB/IIC disease (P = .73). Two patients (14%) developed late relapses. One patient had a pelvic recurrence 11 years after primary RPLND. Final pathology from the pelvic resection demonstrated embryonal carcinoma. He remains disease free after his second surgery. The second patient had a contralateral retroperitoneal recurrence with yolk-sac tumor and teratoma 11 years after primary RPLND. He was treated with chemotherapy followed by postchemotherapy RPLND. CONCLUSION:The relapse rate for patients with teratoma only at primary RPLND is low irrespective of PS. Adjuvant chemotherapy is therefore not recommended in the management of these patients.
