[Laparoscopic Splenectomy for Metachronous Splenic Metastasis of Fallopian Tube Cancer with Synchronous Rectal Metastasis-A Case Report].

A 59-year-old woman underwent simple abdominal total hysterectomy with bilateral salpingo-oophorectomy, partial omentectomy, and extirpation of intrapelvic disseminated nodules for right fallopian tube cancer with rectal metastasis and peritoneal dissemination as primary debulking surgery(PDS). The histopathological diagnosis was high grade serous carcinoma( HGSC)of the right fallopian tube. After adjuvant chemotherapy with 4 courses of paclitaxel-carboplatin(TC), low anterior resection of the rectum for rectal metastasis and pelvic and para-aortic lymph node dissection were performed as interval debulking surgery(IDS). Histopathologically, lymph node metastasis was detected only in the right obturator lymph node. After adjuvant chemotherapy with 4 courses of TC, bevacizumab maintenance monotherapy was administered. Three years after PDS, laparoscopic splenectomy for splenic metastasis and extirpation of the solitary peritoneal metastases were performed as secondary debulking surgery(SDS). After adjuvant chemotherapy with 4 courses of TC, olaparib maintenance monotherapy was administered. The patient has remained alive without recurrence for 4 years after SDS and for 7 years after PDS. No case of metachronous splenic metastasis from fallopian tube cancer with synchronous rectal metastasis has been reported; however, long-term prognosis may be expected with PDS, IDS and SDS for platinum-sensitive HGSC.
