A retrospective analysis of neoadjuvant platinum-based chemotherapy versus up-front surgery in advanced ovarian cancer.

The objective of this study is to compare progression-free survival (PFS) and overall survival (OS) of ovarian cancer patients treated with neoadjuvant chemotherapy and surgery to primary surgery and postoperative chemotherapy. Retrospective analysis from 1998 to 2003 of 116 patients with ovarian cancer was performed. Fifty women diagnosed by positive cytology received three cycles of carboplatin and paclitaxel. Thirty-six patients subsequently underwent cytoreductive surgery and completed three further cycles postoperatively. The OS and PFS were compared in 66 women treated with primary surgery and postoperative chemotherapy. A statistically significant difference was observed for OS (P= 0.03, HR = 1.85, CI = 1.06-3.23) and PFS (P= 0.04, HR = 1.61, CI = 1.03-2.53) favoring the primary surgery group. Due to the small numbers, age, grade, stage, pleural effusions, and histologic cell type were controlled for separately in the bivariate analyses. Controlling for stage made the results weaker. A matched subgroup survival analysis was performed on patients who had surgery following neoadjuvant chemotherapy. After matching for stage and grade and controlling age and pleural effusions (N= 28 matched pairs), there was no statistical difference for OS (P= 0.95, HR = 1.04, CI = 0.33-3.30) or PFS (P= 0.79, HR = 1.11, CI = 0.98-1.04). It is concluded that primary surgery should be considered in all patients. Neoadjuvant chemotherapy may be an alternative in a subset of women with the intent to also perform interval debulking.

Female adnexal tumor of probable wolffian origin: a clinicopathological case report and a possible new treatment.

Female adnexal tumors of probable wolffian origin (FATWOs) are rare tumors arising in the broad ligament from the remnants of the mesonephric duct. We report a case of recurrent disease. A 15-year-old girl who presented with a painful pelvic mass underwent a laparotomy with tumor resection. Pathology findings confirmed a FATWO. The tumor recurred within 2 years and was treated with multiple chemotherapy regimens, including a platinum-based drug, and surgery for progressive disease. The tumor was positive for c-kit oncogene (CD 117). Gleevac therapy, a tyrosine kinase inhibitor, was prescribed, and she developed severe persistent lower abdominal pain 2 months later. She underwent a hysterectomy and debulking of retroperitoneal masses. Pathology showed evidence of tumor necrosis, suggesting a possible beneficial effect, and she was recommenced on Gleevac in an effort to prevent recurrences. She is currently asymptomatic, without evidence of disease 10 months after surgery, continuing on Gleevac therapy. FATWOs are very rare tumors. Most cases are benign but have the potential to recur and metastasize. There is limited knowledge about the optimal treatment for this neoplasm. Our patient's favorable response to Gleevac therapy supports the concept of targeted molecular therapy in patients with c-kit-positive FATWO tumors.

A comparison of laparascopic-assisted radical vaginal hysterectomy and radical abdominal hysterectomy in the treatment of cervical cancer.

OBJECTIVES: The aim of this study was to compare peri-operative morbidity and recurrence-free survival of early-stage cervical cancer patients treated by laparoscopic-assisted radical vaginal hysterectomy (LARVH) with time-matched radical abdominal hysterectomy (RAH) controls at our center. METHODS: Since July 1984, all patients with FIGO stage IA/IB cervical cancer undergoing radical surgery by members of our division have been entered into a prospective database. Since November 1996, one surgeon at our center has performed LARVH on all surgically appropriate patients. Non-parametric tests were used. Differences between medians were compared using Wilcoxon Rank Sum test. Statistical analysis used the Kaplan-Meier method to calculate disease-free survival. Differences between survival curves were compared with the log rank test. Statistical significance was defined as P < 0.05. RESULTS: Between November 1996 and December 2003, 71 and 205 patients have undergone LARVH and RAH, respectively, for FIGO stage IA/IB carcinoma of the cervix. Both groups were similar with respect to age and Quetelet index. There were no differences in tumor size, histology, grade, depth of invasion, lymph node metastases, or surgical margins. All laparoscopic procedures were completed successfully with no conversions to laparotomy. Intra-operative morbidity characteristics analyzed (LARVH vs. RAH) were blood loss 300 ml vs. 500 ml (P < 0.001), operative time 3.5 h vs. 2.5 h (P < 0.001), and intra-operative complications 13% vs. 4% (P < 0.03). Intra-operative complications in the LARVH group included: cystotomy (7), ureteric injury (1), and bowel injury (1). There was no difference in transfusion rates. There was no difference between post-operative infectious and non-infectious complications (LARVH vs. RAH), 9% vs. 5% and 5% vs. 2%, respectively. The median time to normal urine residual was 10 days vs. 5 days (P < 0.001), and the median length of hospital stay was 1 day vs. 5 days (P < 0.001). Twenty-two percent of patients received post-operative radiotherapy for high-risk features in both groups. After a median follow-up of 17 and 21 months, there have been 4 recurrences in the LARVH group and 13 in the RAH (P = NS). The overall 2-year recurrence-free survival was 94% and 94% in the LARVH and RAH groups, respectively (P = NS). CONCLUSION: Our data demonstrate that early cervical cancer can be treated successfully with LARVH with similar efficacy and recurrence rates to RAH. The major benefits are less intra-operative blood loss and shorter hospital stay. It is a safe procedure with low overall morbidity and complication rates. However, at present, LARVH is associated with an increase in intra-operative complications, and patients may have an increased time to return to normal bladder function.
