Feasibility and perioperative outcomes of robotic-assisted surgery in the management of recurrent ovarian cancer: a multi-institutional study.

OBJECTIVES: Minimally invasive surgery for recurrent ovarian cancer is generally not performed. The aim of this study was to assess the feasibility and surgical outcomes of robotic-assisted surgery in the management of recurrent ovarian cancer. METHODS: Eligible patients included those with confirmed recurrent ovarian cancer amenable to surgical resection and in which a complete resection was thought to be feasible with the use of the robotic platform. Patients with evidence of carcinomatosis were not considered for a robotic approach. Clinical and pathologic data were abstracted from the medical records. Appropriate statistical tests were performed using SPSS statistical software program (SPSS 20.0 Inc., Chicago, IL). RESULTS: A total of 48 patients were identified. Thirty-six (75%) patients had a recurrent mass or masses isolated to one anatomic region (pelvis or abdomen). Conversion to laparotomy was necessary in 4 (8.3%) cases. In cases not requiring conversion to laparotomy, the median operative time, EBL, and length of stay were 179.5 min, 50 cc, and 1 day, respectively. An optimal debulking was achieved in 36 (82%) cases. Complications occurred in 6 (13.6%) cases. The median operative time, EBL, length of stay, and complications were all statistically significantly lower in the cases not converted to laparotomy compared to those that were (p\u3c0.001). CONCLUSIONS: This study suggests that select patients with recurrent ovarian cancer in the absence of carcinomatosis may be candidates for secondary surgical cytoreduction via a robotic approach. Surgical and postoperative outcomes appear to be favorable compared to reports of laparotomy in recurrent ovarian cancer

Development of endometrial cancer after radiation treatment for cervical carcinoma.

OBJECTIVE: To detail the Memorial Sloan-Kettering Cancer Center and MD Anderson Cancer Center experience with 23 patients treated with radiation therapy for invasive cervical carcinoma who subsequently developed endometrial carcinoma. METHODS: We conducted a retrospective chart and pathology review on patients diagnosed with endometrial cancer between 1976 and 2000 who had previously received definitive radiation treatment for cervical cancer. Abstracted data included patient demographics, type of radiation therapy, histological grade, histological subtype, and stage of endometrial cancer. RESULTS: The mean age at endometrial cancer diagnosis was 64.4 years (range 53-80), and the average latency period from initial therapy to development of endometrial carcinoma was 14 years (range 6-27). Distribution by stage, grade, and histology was as follows: stage I, five (22%); stage II, one (4%); stage III, nine (39%); stage IV, seven (30%); unknown stage, one (4%); grade 1, one (4%); grade 2, three (13%); grade 3, 17 (74%); unknown grade, two (9%); carcinosarcoma, eight (35%); endometrioid, four (17%); papillary serous, six (26%); clear cell, one (4%); mucinous, one (4%); undifferentiated, one (4%); and unknown histology, two (9%). The median survival was 24 months, and the 2- and 5-year survival rates were 50% (95% confidence interval [CI] 31.4%, 78.9%) and 21% (95% CI 8.1%, 56.3%), respectively. CONCLUSION: Patients treated with definitive radiation therapy for invasive cervical cancer may still have viable endometrium at risk for neoplasia. Endometrial cancers that develop after radiation treatment have a preponderance of high-risk histological subtypes and, consequently, a poor prognosis
