Article: Quaternary cytoreductive surgery in ovarian cancer: does surgical effort still matter?
[show abstract] [hide abstract]
ABSTRACT: Background:To evaluate surgical outcome and survival benefit after quaternary cytoreduction (QC) in epithelial ovarian cancer (EOC) relapse.Methods:We systematically evaluated all consecutive patients undergoing QC in our institution over a 12-year period (October 2000-January 2012). All relevant surgical and clinical outcome parameters were systematically assessed.Results:Forty-nine EOC patients (median age: 57; range: 28-76) underwent QC; in a median of 16 months (range:2-142) after previous chemotherapy. The majority of the patients had an initial FIGO stage III (67.3%), peritoneal carcinomatosis (77.6%) and no ascites (67.3%). At QC, patients presented following tumour pattern: lower abdomen 85.7%; middle abdomen 79.6% and upper abdomen 42.9%. Median duration of surgery was 292 min (range: a total macroscopic tumour clearance could be achieved. Rates of major operative morbidity and 30-day mortality were 28.6% and 2%, respectively.Mean follow-up from QC was 18.41 months (95% confidence interval (CI):12.64-24.18) and mean overall survival (OS) 23.05 months (95% CI: 15.5-30.6). Mean OS for patients without vs any tumour residuals was 43 months (95% CI: 26.4-59.5) vs 13.4 months (95% CI: 7.42-19.4); P=0.001. Mean OS for patients who received postoperative chemotherapy (n=18; 36.7%) vs those who did not was 40.5 months (95% CI: 27.4-53.6) vs 12.03 months (95% CI: 5.9-18.18); P<0.001.Multivariate analysis indentified multifocal tumour dissemination to be of predictive significance for incomplete tumour resection, higher operative morbidity and lower survival, while systemic chemotherapy subsequent to QC had a protective significant impact on OS. No prognostic impact had ascites, platinum resistance, high grading and advanced age.Conclusion:Even in this highly advanced setting of the third EOC relapse, maximal therapeutic effort combining optimal surgery and chemotherapy appear to significantly prolong survival in a selected patients 'group'.British Journal of Cancer 01/2013; 108(1):32-8. · 5.04 Impact Factor -
Article: Feasibility of surgery after systemic treatment with the humanized recombinant antibody bevacizumab in heavily pretreated patients with advanced epithelial ovarian cancer.

ABSTRACT: The aim of this study was to assess operative feasibility and outcome after bevacizumab treatment (BT) in ovarian cancer (OC) patients. We retrospectively identified all OC patients operated between April 2006 and September 2010 after BT. We identified 733 OC operations, 10 of which (1.36%) were performed in a mean time of 134 days (range, 10-288) after BT. Indication was secondary cytoreduction in 3 patients (mean days after BT, 181; range, 82-256) and palliation in 7 due to bowel obstruction and/or intestinal perforation or fistula (mean days after BT, 114; range, 10-288). All but 1 acutely operated patients developed a secondary wound healing, but none of the 3 patients after planned cytoreduction did. Of these 3 patients, 1 suddenly died on the 36th postoperative day, presumably of thromboembolism. None of the patients developed postoperatively a gastrointestinal morbidity; however, in 1 patient operated 21 days after BT due to a vesicointestinal fistula the bladder reconstruction could not heal and developed a permanent fistula. Emergency surgery after BT due to bowel obstruction and/or fistulas seems to be associated with an impaired wound healing in advanced heavily pretreated platinum-resistant OC patients, while this does not appear the case in planned cytoreduction. Prospective evaluations are warranted to assess surgical safety after BT in this special patients' collective.Annals of Surgical Oncology 11/2011; 19(4):1326-33. · 4.17 Impact Factor
