Prognostic predictors and spread patterns in adult ovarian granulosa cell tumors: a multicenter long-term follow-up study of 108 patients.

PURPOSE: To identify prognostic predictors and spread patterns in adult ovarian granulosa cell tumors (OGCTs). METHODS: Available retrospective data of 108 OGCT patients managed at three centers between January 1, 1991 and December 31, 2010 were abstracted and analyzed. RESULTS: Stage distributions at diagnosis for stage I, II and III OGCT were 84.3, 5.4, and 9.3 %, respectively. Optimal cytoreduction with no macroscopically visible disease was achieved in 99/108 (91.6 %) patients. The median disease-free interval to first recurrence was 61 months. The overall 5- and 10-year survival rates were 93.3 and 90.9 %, respectively. Disease recurred in 18 (16.6 %) patients, and 8 (7.4 %) patients died of their disease. The first recurrence sites included the pelvic peritoneum (n = 10), liver/liver-capsule (n = 5), rectosigmoid colon (n = 4), retroperitoneal lymph nodes (n = 3), omentum (n = 3), small bowel mesenterium (n = 2), and vaginal cuff (n = 2). Multiple-site recurrence was observed in 9/18 (50 %) patients. Secondary cytoreduction requiring extensive surgery was performed in 14 patients with an optimality rate of 71.4 %. The remaining four patients received only chemotherapy. Multivisceral approaches, including pelvic peritonectomy (n = 9; 64.2 %), rectosigmoid resection (n = 3; 21.4 %), and segmental liver capsule resection (n = 2; 14.2 %) were performed more frequently during the secondary surgery. Definitive retroperitoneal lymph node metastasis rates at the initial and recurrent settings were 5.1 % (3/58) and 21.4 % (3/14), respectively. Both stage and residual tumor status were significantly associated with recurrence in univariate and multivariate analyses. CONCLUSIONS: Stage and residual tumor status are predictors of recurrence. Pelvic peritoneal, nodal and hepatic involvement, and multiple-site spread patterns requiring extensive cytoreductive surgery are likely associated with recurrence of OGCTs.

Long-term oncological and reproductive outcomes of fertility-sparing cytoreductive surgery in females aged 25 years and younger with malignant ovarian germ cell tumors.

AIM: To evaluate the long-term oncological and reproductive outcomes of patients aged 25 years and younger who were treated by fertility-sparing cytoreductive surgery (FSCS) plus adjuvant chemotherapy (ACT) or observation alone for malignant ovarian germ cell tumors (MOGCT). METHODS: Records of 42 eligible female patients treated for MOGCT between 1 May 1995 and 31 December 2010 at two centers were analyzed retrospectively. A telephone questionnaire was performed to gather reproductive and menstrual history. RESULTS: One patient was treated without FSCS and two patients were lost to follow-up. The mean age of the remaining 39 patients was 18.4 ± 3.2 years. Eighteen of the tumors were histologically pure dysgerminomas (PD) and 21 were non-dysgerminomatous tumors (non-DT). Thirteen patients (33%) presented with stage II-III disease. Optimal cytoreduction was achieved in 34 of the 39 patients (87%). Systematic pelvic and para-aortic lymphadenectomy was performed in 31 of the 39 patients (79.5%). The frequency of lymph node metastasis was 29% (9/31). Twenty-seven patients (69.2%) received ACT. Disease recurred in six (15.3%) patients, all in the non-DT group. Four of six underwent secondary optimal FSCS followed by chemotherapy. Retroperitoneal nodal recurrence was detected in two of these four patients (50%). Four deaths occurred, three due to chemoresistant aggressive disease and one due to secondary acute myelocytic leukemia. The overall survival rates for patients with PD and non-DT were 100% and 81.4%, respectively. Twenty-three of 27 patients who received ACT continued their regular menses. Sixteen spontaneous pregnancies and one pregnancy by intrauterine insemination were achieved by 21 patients who attempted conception. CONCLUSION: Either primary or secondary FSCS followed by ACT seems to be a feasible and safe approach to preserving future fertility and hormonal function in young patients with MOGCT.
