Complete reduction surgery of a huge recurrent adult granulosa cell tumor after neoadjuvant chemotherapy.

Abstract

Adult granulosa cell tumors are rare, accounting for only 3-5% of all ovarian tumors. Adult granulosa cell tumors have late recurrences, for which complete resection is an effective option. We report a patient who underwent complete resection of a huge recurrent adult granulosa cell tumor after neoadjuvant chemotherapy. A 72-year-old woman underwent primary surgery for an adult granulosa cell tumor 19years earlier. A huge recurrent tumor, 11 × 10cm in size, was noted to elevate the hepatic hilum, inferior vena cava, and right renal vein. The recurrent tumor was too large to resect, thus paclitaxel and carboplatin were administered as neoadjuvant chemotherapy. The tumor shrank to 6 × 5cm after 6 cycles of chemotherapy, then complete tumor extirpation with resection of the right kidney and temporary scission of inferior vena cava was performed. The patient was alive and well without evidence of a recurrence 1 y postoperatively. Paclitaxel and carboplatin, as neoadjuvant chemotherapy, might be an effective treatment option to achieve complete reduction surgery. This is the first report demonstrating the effectiveness of paclitaxel and carboplatin for huge recurrent adult granulosa cell tumor.
