Morbidity of rectosigmoid resection and primary anastomosis in patients undergoing primary cytoreductive surgery for advanced epithelial ovarian cancer

OBJECTIVES: Studies from the colorectal literature have shown that factors associated with anastomotic leak after colorectal resection include long surgical time (>2 h), multiple blood transfusions, and short distance to the anal verge. The aim of this study was to assess the morbidity associated with en bloc resection of ovarian carcinoma with low anterior resection and anastomosis in patients undergoing primary cytoreductive surgery for advanced disease. METHODS: We performed a retrospective chart review of all patients who had undergone primary cytoreduction for advanced epithelial ovarian cancer with rectosigmoid resection followed by low rectal anastomosis between January 1994 and June 2004. Patient characteristics, operative details, and postoperative complications were extracted from patients' charts. RESULTS: Seventy patients met the above criteria and form our study group. The median age was 59 years (range, 25-82). There were 52 stage IIIC (74%) and 18 stage IV (26%) cancers. The median operating time was 315 min (range, 120-750) and the median estimated blood loss was 1200 ml (range, 250-8000), with 53 (76%) patients requiring blood transfusion. Twenty-eight patients (40%) underwent major upper abdominal procedures other than omentectomy, and 14 patients (20%) underwent a second bowel resection. Twelve patients (17%) underwent a protective ileostomy while the remainder (83%) did not. Of the 58 patients with no ostomy, the only complications associated with the resection and anastomoses were a pelvic abscess in 3 patients (5%) and an anastomotic leak requiring diverting colostomy in 1 patient (1.7%). Of the 12 patients who had protective ileostomies, 3 (25%) had complications related to their ileostomy short-bowel syndrome requiring early reversal, incarceration of the prolapsed loop requiring surgical correction, and prolapse corrected electively at the time of second-look surgery. CONCLUSIONS: In women undergoing primary cytoreductive surgery, the morbidity associated with en bloc resection of ovarian carcinoma with low rectosigmoid resection and anastomosis without protective ileostomy was acceptably low, with an anastomotic leak rate of less than 2%. Protective ileostomy is not always necessary and should be used selectively.     

Secondary cytoreductive surgery for isolated nodal recurrence in patients with epithelial ovarian cancer

OBJECTIVES: To evaluate the feasibility and associated survival outcome of secondary cytoreductive surgery in patients with isolated lymph node recurrence of epithelial ovarian cancer. METHODS: Twenty-five patients with epithelial ovarian cancer who underwent secondary cytoreductive surgery for isolated lymph node recurrence were identified from tumor registry databases. Demographic, diagnostic, operative, pathologic, and follow-up data were abstracted retrospectively. Overall survival was calculated using the Kaplan-Meier method. RESULTS: The median age at time of primary surgery for ovarian cancer was 55 years; 72% of patients had FIGO III/IV disease, and all had high-grade tumors. All patients received platinum-based chemotherapy following primary surgery. The median time from completion of primary chemotherapy to nodal recurrence surgery was 16 months (range=6 to 40 months). The distribution of nodal involvement was pelvic=12% (n=3), para-aortic=60% (n=15), inguinal=20% (n=5), peri-cardiac=4% (n=1), and pelvic plus para-aortic=4% (n=1). The maximal nodal tumor diameter ranged from 1.5 cm to 14 cm, with a median of 3.0 cm. Optimal secondary cytoreductive surgery (residual disease 相似文献   

The feasibility and morbidity of distal pancreatectomy in extensive cytoreductive surgery for advanced epithelial ovarian cancer

Introduction Pancreatic metastasis of ovarian cancer is extremely rare and its therapeutic approach is not well documented. The objective of this study is to evaluate the feasibility and morbidity of pancreatic resection as a component of extensive cytoreductive surgery in epithelial ovarian cancer (EOC) patients with pancreas metastasis.Methods Between December 2000 and February 2003, 98 EOC patients were treated with primary cytoreduction. Six (6.12%) of these patients had pancreatic tail metastasis and were operated on using the distal pancreatectomy.Results Preoperatively, only 1 (16.7%) of the 6 patients had signs of metastasis to the pancreas on computed tomography (CT). Optimal cytoreduction (absent or 1 cm macroscopic residual tumor size) was achieved in all patients. In the early postoperative period, there were 4 patients (66.7%) with complications and no perioperative mortality. In 1 patient (16.7%), glucose intolerance as a late complication of pancreatic resection was detected. All patients received six cycles of platinum-based adjuvant chemotherapy following a cytoreductive operation. Mean follow-up was 27 months (range 9–36), and 3 (50%) patients are still alive at the end of the study period. The two-year survival rate was 66.7%.Conclusion In conclusion, if optimal cytoreduction is foreseen in advanced epithelial ovarian cancer with pancreatic tail metastasis, distal pancreatectomy should be kept in mind. This procedure has acceptable morbidity and seems to be an attribute for survival.     

Safety and efficacy of low anterior en bloc resection as part of cytoreductive surgery for patients with ovarian cancer

OBJECTIVE: To examine the feasibility and safety of a low anterior resection of the rectosigmoid plus adjacent pelvic tumour as part of primary cytoreduction for ovarian cancer. METHODS: This study included 65 consecutive patients with primary ovarian cancer who had debulking surgery from 1996 through 2000. All patients underwent an en bloc resection of ovarian cancer and a rectosigmoid resection followed by an end-to-end anastomosis. Parameters for safety and efficacy were considered as primary statistical endpoints for the aim of this analysis. RESULTS: Postoperative residual tumour was nil, <1 cm, and >1 cm in 14, 34, and 14 patients, respectively. The median postoperative hospital stay was 11 days (range, 6 to 50 days). Intraoperative complications included an injury to the urinary bladder in one patient. Postoperative complications included wound complications (n = 14, 21.5%), septicemia (n = 9, 13.8%), cardiac complications (n = 7, 10.8%), thromboembolic complications (n = 5, 7.7%), ileus (n = 2, 3.1%), anastomotic leak (n = 2, 3.1%), and fistula (n = 1, 1.5%). Reasons for a reoperation during the same admission included repair of an anastomotic leak (n = 1), postoperative hemorrhage (n = 1), and wound debridement (n = 1). Wound complications, septicemia, and anastomotic leak formation were more frequent in patients who had a serum albumin level of < or =30 g/L preoperatively. There was one surgically related mortality in a patient who died from a cerebral vascular accident 2 days postoperatively. CONCLUSIONS: An en bloc resection as part of primary cytoreductive surgery for ovarian cancer is effective and its morbidity is acceptably low.     

Celiac lymph node resection and porta hepatis disease resection in advanced or recurrent epithelial ovarian, fallopian tube, and primary peritoneal cancer

Introduction

Prognostic value of complete macroscopic resection of primary disease has been reported and confirmed in several publications. Published data indicate that extensive upper abdominal disease involving the hepatic pedicle and celiac trunk is associated with an abortion of the surgical procedure or with suboptimal residual disease.

Methods

All patients who had disease at the porta hepatis or celiac lymph node resection as part of cytoreductive surgery were included. Medical and operative records with particular emphasis on extent and distribution of disease spread, number of peritonectomy procedures, visceral resections, and lymphadenectomy procedures were examined.

Results

A total of 28 patients who underwent some kind of celiac lymph node resection or resection of metastatic involvement of the porta hepatis were included. Median preoperative serum Ca-125 level was 78 U/ml (range, 30-2950 U/ml), and median ascites volume was 1900 ml (range, 0-10,000 ml). Of the 28 patients, 23 underwent supra-radical surgery for diffuse peritoneal carcinomatosis. Median operative time was 252 minutes (range, 100-540 minutes). Complete cytoreduction to CCO was achieved in all except one case, who was cytoreduced to millimetric residue. Fifteen patients had positive celiac nodes and nineteen patients had peritoneal disease in the porta hepatis region.

Discussion

Resection of enlarged nodes and metastatic disease to the porta hepatis is feasible with an acceptable morbidity. The decision to undergo an aggressive cytoreductive surgery is based on appropriate patient selection depending on the extension of surgical procedure, on medical comorbidities, and on the potential to tolerate an extensive procedure, rather than on specific anatomic locations.     

Secondary cytoreductive surgery for recurrent platinum-sensitive ovarian cancer

Objective

To determine the risks and benefits of secondary cytoreductive surgery for recurrent platinum-sensitive ovarian cancer.

Methods

Data were obtained retrospectively for all women with recurrent platinum-sensitive epithelial ovarian cancer who underwent a second debulking operation between 1998 and 2008 at the University of Texas Southwestern Medical Center. Survival analysis and comparisons were performed using the Kaplan-Meier method, log-rank test, and Cox multivariate proportional hazards model.

Results

Optimal secondary cytoreductive surgery (< 5 mm of residual disease) was achieved in 32 of 40 patients (80%). Nine women (23%) developed major complications. Two variables, residual disease of less than 5 mm vs 5 mm or greater (median 63 months vs 11 months; P = 0.003); and less than 5 vs 5 or more sites of disease relapse (median 63 months vs 22 months; P = 0.009), were independently associated with survival and retained prognostic significance on multivariate analysis.

Conclusions

Optimal secondary cytoreductive surgery was associated with a survival advantage and acceptable risks.     

Perioperative fluid status and surgical outcomes in patients undergoing cytoreductive surgery for advanced epithelial ovarian cancer

Objective

The objective of this study is to investigate the impact of fluid status on perioperative outcomes of patients undergoing cytoreductive surgery (CRS) for advanced epithelial ovarian cancer (EOC).

Predictive value of PET-CT imaging versus AGO-scoring in patients planned for cytoreductive surgery in recurrent ovarian cancer

Objective

To assess the predictive value of positron emission tomography computed tomography (PET–CT) imaging in comparison to AGO-scoring in patients planned for cytoreductive surgery in recurrent ovarian cancer.

Materials and methods

33 patients who had received a PET–CT for suspicion of recurrent ovarian cancer between 12/2003 and 08/2007 were included in the retrospective analysis. Indication for PET–CT was based on blood tumor markers Ca 125 or Ca 72-4 and clinical symptoms. Scanning was performed on a Philips Gemini System covering the body from the neck to the thighs one hour after administration of 200 MBq fluorodesoxyglucose. PET–CT, surgery and the patient records were reviewed to analyze the predictive value of PET–CT in comparison to an AGO-scoring system based on clinical parameters with regard to the prediction of full resectability of abdominal tumor spread.

Results

The statistical analysis of this data showed a sensitivity of 73% (95% C.I., 39–94%) and specificity of 80% (95% C.I., 29–97%) for AGO-scoring with a positive predictive value of 89% and a negative predictive value of 57%. PET–CT achieved a sensitivity of 100% (95% C.I., 72–100%) and specificity of 60% (95% C.I. 15–94%), with a positive predictive value of 85% and negative predictive value of 100%. Further analysis of the data of operated patients with concordant PET–CT and AGO-score (12/16) showed a very good prediction of full resectability with a sensitivity of 100% (95% C.I., 63–100%), specificity of 75% (95% C.I., 20–96%), positive predictive value of 89% and negative predictive value of 100%.

Conclusion

PET–CT and the AGO-score offer good tools to determine patients for full resectability in recurrent ovarian cancer. PET–CT has a higher negative and the AGO score a higher positive predictive value, and the combination of both improves the diagnostic accuracy.     

Cytoreductive surgery for patients with recurrent epithelial ovarian carcinoma

OBJECTIVE: This study aims to identify favorable preoperative characteristics and examine the impact of secondary cytoreductive surgery on survival for patients with recurrent epithelial ovarian carcinoma. METHODS: Patients who underwent cytoreductive surgery for recurrent epithelial ovarian cancer were identified in our surgical database for the period 1988-2004. Patient charts were reviewed and data collected regarding patient demographics, surgical management, preoperative evaluation, perioperative complications, and oncologic outcome. RESULTS: Eighty-five patients met eligibility criteria. Preoperative factors that correlated with improved survival were disease-free interval of greater than 12 months (p<0.01) and residual disease after primary surgery of <2 cm (p<0.02). Other preoperative factors evaluated but not found significant included radiographic findings, physical findings, previous histology, stage, grade, previous chemotherapy, prior recurrence, and serum CA-125 level. Optimal resection to <1 cm residual disease was achieved in 86% of patients who had secondary cytoreduction. Small bowel and colon resection for cytoreduction occurred in 7% and 51% of patients, respectively. Operative complications occurred in 14% and postoperative complications occurred in 21% of patients. The median survival of patients who were optimally cytoreduced to <1 cm was 30 months compared to 17 months for patients with residual disease>or=1 cm (p<0.05). Operative factors that were evaluated and did not significantly effect survival were location of recurrence, presence of ascites, and extent of recurrence. Recurrent or progressive disease occurred in 75% of patients during follow-up. CONCLUSION: When selecting patients for secondary cytoreduction, the most significant preoperative factors are disease-free interval and success of a prior cytoreductive effort. Once secondary cytoreductive surgery is attempted, the most important factor for improved survival is optimal cytoreduction. Of equal importance is counseling regarding the significant risk for bowel surgery, colostomy, and complications.     

En bloc resection of diaphragm with lung for recurrent ovarian cancer: a case report

INTRODUCTION: Multiple series have demonstrated the feasibility of full-thickness diaphragm resection for ovarian cancer metastatic to the diaphragm. However, direct extension of tumor into the lung is sometimes encountered, and successful resection of this type of implant has not been previously described in the gynecologic oncology literature. CASE REPORT: We present the first case of en bloc full-thickness diaphragm resection including a portion of lung tissue using the EndoGIA stapler with primary diaphragmatic closure. DISCUSSION: En bloc full-thickness diaphragm resection including a portion of lung tissue using the EndoGIA stapler is a safe, feasible, and effective method to optimize cytoreduction with disease-free margins in the context of invasive diaphragmatic ovarian cancer metastasis.     

Cytoreductive surgery and HIPEC after neoadjuvant chemotherapy for advanced epithelial ovarian cancer

AIM: To reduce postoperative complications and to make possible an optimal cytoreduction, neoadjuvant chemotherapy (NACT) followed by interval debulking surgery has been applied with encouraging results. METHODS: Between December 2009 and February 2012, patients with stage IIIC-IV epithelial ovarian cancer (EOC) underwent diagnostic laparoscopy, to assess the feasibility of optimal debulking surgery. The modified Fagotti score was applied to assess the feasibility of resection with zero residual tumor. Patients who were not candidate for upfront debulking surgery were submitted to NACT, then reassessed according to the RECIST 1.1 criteria and submitted to cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) if they showed clinical response or stable disease. The remaining cycles of adjuvant systemic chemotherapy (ASCT) were administered postoperatively, to complete 6 cycles of systemic chemotherapy. RESULTS: Nine patients were included. Clinical response to NACT was complete in 3 patients and partial in 5 patients; one patient had stable disease. All patients underwent CRS resulting in CC0 disease prior to HIPEC. Average operative time was 510 min. Average intensive care unit stay was 2 d. Average postoperative hospital stay was 25 d. No postoperative mortality was observed. One patient experienced pelvic abscess. One patient refused ASCT. The remaining 8 patients started ASCT. Average time to chemotherapy was 36 d. All patients are alive, with an average follow up of 11 mo. Eight patients are disease-free at follow up. CONCLUSION: HIPEC after CRS for advanced EOC is feasible with acceptable morbidity and mortality. NACT may increase the chance for achieving complete cytoreduction. Phase 3 studies are needed to determine the effects of HIPEC on survival.     

Impact of a structured quality management program on surgical outcome in primary advanced ovarian cancer

Objective

Surgical outcome in advanced ovarian cancer (AOC) is an important prognostic factor and the only factor amendable to improvement by optimization. Therefore, introduction of quality management programs (QM) regarding the surgical therapy in ovarian cancer may help to improve outcome.

Methods

We introduced a specific ovarian cancer quality management program in 2001 in our gynecologic oncology center. Analysis of 396 consecutive patients with primary surgery for advanced ovarian cancer FIGO stages IIB-IV operated before the introduction of the quality management program 1997-2000, or during the introduction years 2001-2003, or after establishing 2004-2008.

Results

Thirty-three percent had complete debulking to no macroscopic residual disease from 1997 to 2000. This rate increased to 47% in 2001-2003 (n = 86) and 62% in 2004-2008 (n = 259). The utilization of extended surgical procedures increased over time. Patients with complete resection had 5-YSR of 55% compared to 16% in patients with residuals 1-10 mm, and 13% in patients with residuals > 1 cm (p < 0.001). The median OS increased from 26 months 1997-2000 to 37 months 2001-2003 and 45 months in 2004-2008 (p < 0.003).

Conclusions

Optimizing surgical skills, infrastructure, and introduction of quality management programs may improve both surgical and overall outcome in advanced ovarian cancer.     

Nomogram for predicting 5-year disease-specific mortality after primary surgery for epithelial ovarian cancer

Objective

To develop a nomogram based on established prognostic factors to predict the probability of 5-year disease-specific mortality after primary surgery for patients with all stages of epithelial ovarian cancer (EOC) and compare the predictive accuracy with the currently used International Federation of Gynecology and Obstetrics (FIGO) staging system.

Methods

Using a prospectively kept database, we identified all patients with EOC who had their primary surgery at our institution between January 1996 and December 2004. Disease-specific mortality was estimated using the Kaplan-Meier method. Twenty-eight clinical and pathologic factors were analyzed. Significant factors on univariate analysis were included in the Cox proportional hazards regression model, which identified factors utilized in the nomogram. The concordance index (CI) was used as an accuracy measure, with bootstrapping to correct for optimistic bias. Calibration plots were constructed.

Results

A total of 478 patients with EOC were included. The most predictive nomogram was constructed using seven variables: age, FIGO stage, residual disease status, preoperative albumin level, histology, family history suggestive of hereditary breast/ovarian cancer (HBOC) syndrome, and American Society of Anesthesiologists (ASA) status. This nomogram was internally validated using bootstrapping and shown to have excellent calibration with a bootstrap-corrected CI of 0.714. The CI for FIGO staging alone was significantly less at 0.62 (P = 0.002).

Conclusion

We have developed an all-stage nomogram to predict 5-year disease-specific mortality after primary surgery for epithelial ovarian cancer. This tool is more accurate than FIGO staging and should be useful for patient counseling, clinical trial eligibility, postoperative management, and follow-up.     

Cost effectiveness of neoadjuvant chemotherapy followed by interval cytoreductive surgery versus primary cytoreductive surgery for patients with advanced stage ovarian cancer during the initial treatment phase

Objective

Advanced stage epithelial ovarian cancer (AEOC) can be treated with either neoadjuvant chemotherapy (NACT) or primary cytoreductive surgery (PCS). Although randomized controlled trials show that NACT is non-inferior in overall survival compared to PCS, there may be improvement in short-term morbidity. We sought to investigate the cost-effectiveness of NACT relative to PCS for AEOC from the US Medicare perspective.

A phase II trial of weekly topotecan for patients with secondary platinum-resistant recurrent epithelial ovarian carcinoma following the failure of second-line therapy

OBJECTIVE: To determine the response rate, progression-free survival and toxicity associated with weekly topotecan administered to patients with platinum-sensitive recurrent epithelial ovarian (EOC) in the third-line setting. METHODS: Patients with measurable platinum-sensitive EOC following failure of second-line chemotherapy were eligible for this phase II study. All patients were initially treated with cytoreductive surgery and platinum/paclitaxel-based chemotherapy. Continuous, weekly topotecan was administered at a starting dose of 4 mg/m(2). Toxicity and efficacy were assessed at various time points after initiation of therapy. RESULTS: Twenty nine patients were enrolled in this prospective study. Toxicity was acceptable with grade 1/2 nausea being the most commonly experienced side effect (52%). Nine patients (31%) had grade 3/4 leukopenia; however, only 3 patients had febrile neutropenia. Thirteen patients had a treatment delay and six required dose reductions. Twenty two patients were evaluable for efficacy. The overall response rate for weekly topotecan was 13.6% [95% CI; -0.7-27.9%] with 1 complete response, and 2 partial responses. Twelve patients (54.5%), including 2 with minor responses, had stable disease for a median duration of 18 weeks. CONCLUSIONS: Weekly topotecan at the current schedule in the third-line setting in patients with platinum-sensitive recurrent EOC has modest clinical activity. Toxicity associated with this regimen is acceptable but growth factor support, dose reductions, or schedule alterations may need to be considered in many of these patients.     

中间性肿瘤细胞减灭术对晚期卵巢癌治疗的价值

1 目的 探讨中间性肿瘤细胞减灭术在晚期卵巢癌治疗中的价值。方法 将曾行肿瘤细胞减灭术的晚期上皮性卵巢癌患者按照术前是否化疗分为两组,即初次肿瘤细胞减灭术组和中间性肿瘤细胞减灭术组,进行回顾性分析,比较两组患者与预后有关的指标及生存情况。结果1990年1月～1998年12月,收治ⅢC期、Ⅳ期上皮性卵巢癌患者,并施行了肿瘤细胞减灭术者共71例。其中行初次肿瘤细胞减灭术者45例,行中间性肿瘤细胞减灭术者26例。两组患者除中间性肿瘤细胞减灭术组在术前给予2～4疗程化疗外,手术范围基本相同。中间性肿瘤细胞减灭术组期别晚、分级高,预后不良的组织病理类型所占比例高,但治疗结果两组间达到满意肿瘤细胞减灭术的比例无明显差别。追踪随访初次肿瘤细胞减灭术组,5年生存率40.60％;中间性肿瘤细胞减灭术组,5年生存率对30.72%(P>0.8)。结论 对术前估计难以达到满意的肿瘤细胞减灭术晚期卵巢癌患者,行中间性肿瘤细胞减灭术有可能提高生存率。
