Urinary and fecal incontinence in patients with advanced ovarian cancer treated with CRS + HIPEC.

PURPOSE: The objective of this work was to analyze the long-term prevalence of urinary and fecal incontinence and their impact on quality of life in patients with advanced and recurrent ovarian cancer treated with cytoreductive surgery and hyperthermic intraoperative intraperitoneal chemotherapy (CRS + HIPEC). METHODS: This cross-sectional study included a series of patients with advanced and recurrent ovarian cancer treated by CRS + HIPEC, with a disease-free period of at least 12 months after the procedure. Urinary incontinence was evaluated using the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF), fecal incontinence using the Wexner test and the Fecal Incontinence Quality of Life (FIQL) questionnaire and global quality of life using the Short Form 36 (SF-36) survey. RESULTS: A total of 64 patients were included in the study, with a median age of 55 years (range 28-78). The urinary incontinence rate was 45% and the fecal incontinence rate was 20%. Up to 14% of the patients presented both types of incontinence. The presence of urinary or fecal incontinence generated a significant negative impact on quality of life in relation to patients without incontinence. DISCUSSION: Urinary and fecal incontinence is frequent in the follow-up of ovarian cancer patients treated with CRS + HIPEC. Reconsidering the approach to the pelvis without peritoneal metastases in the peritoneum could modify the incidence of these pelvic floor dysfunctions.

Identifying the incidence of respiratory complications following diaphragmatic cytoreduction and hyperthermic intraoperative intraperitoneal chemotherapy.

INTRODUCTION: In patients with peritoneal carcinomatosis (PC), the incidence of respiratory complications following cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is not well established. We aimed to describe the center-specific incidence and patient characteristics associated with respiratory complications following CRS and HIPEC in patients receiving treatment for PC. MATERIALS AND METHODS: We used the University Hospital of Arrixaca study database to identify patients who underwent CRS and HIPEC for PC. Patients who experienced a post-operative respiratory complication were categorized according to the National Cancer Institute-Common Terminology Criteria for Adverse Events. Multivariable regression methods were used to identify independent risk factors for developing a respiratory complication following CRS and HIPEC. RESULTS: Between 2008 and 2017, we identified 247 patients who underwent CRS and HIPEC for PC. A total of eight patients (3.2%) were categorized as having a post-operative respiratory complication. A diaphragmatic peritonectomy and a PC index of > 14 were identified as independent risk factors for developing a respiratory complication. Radiographic evidence of a pleural effusion was identified in 72 patients who had CRS of the diaphragmatic peritoneum; however, only 6 (8.3%) of these patients required pleural drainage. CONCLUSIONS: Only 3.2% of patients developed a symptomatic respiratory complication following CRS and HIPEC. A pleural effusion was identified in almost all patients requiring a diaphragmatic peritonectomy as part of their CRS; however, less than one in ten of these patients required pleural drainage. Prophylactic insertion of a pleural drainage tube is, therefore, not indicated following CRS and HIPEC.

The role of hyperthermic intraperitoneal chemotherapy using paclitaxel in platinum-sensitive recurrent epithelial ovarian cancer patients with microscopic residual disease after cytoreduction.

BACKGROUND: We analyzed the role of hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) on the microscopic component of the disease in patients with a first recurrence of platinum-sensitive ovarian cancer after complete cytoreduction (CCR). PATIENTS AND METHODS: We analyzed the data of 54 patients who were operated on between January 2001 and July 2012 with the diagnosis of platinum-sensitive recurrent ovarian cancer. In all patients, it was possible to achieve a CCR. Patients were divided into two groups: group I (cytoreduction alone) consisted of 22 surgical patients and group II (cytoreduction and HIPEC) consisted of 32 patients. RESULTS: There were no significant differences in any of the preoperative variables studied. After a multivariate analysis of factors identified in the univariate analysis, only the presence of tumors with undifferentiated histology (hazard ratio 2.57; 95% CI 1.21-5.46; p < 0.05) was an independent factor associated with a reduced disease-free survival. The 1- and 3-year disease-free survival was 77 and 23% in patients from group I and 77 and 45% in patients from group II, respectively, with a tendency, but no significant differences (p = 0.078). There was no significant difference in postoperative morbidity between the two groups. CONCLUSIONS: The administration of HIPEC in patients in whom it is possible to achieve a CCR of the disease has not increased postoperative morbidity and mortality rates in our center. HIPEC with paclitaxel is effective in the treatment of microscopic disease in platinum-sensitive recurrent epithelial ovarian cancer patients with microscopic residual disease after cytoreduction, although with no statistically significant difference.

Treatment of microscopic disease with hyperthermic intraoperative intraperitoneal chemotherapy after complete cytoreduction improves disease-free survival in patients with stage IIIC/IV ovarian cancer.

BACKGROUND: We analyze the efficacy of hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) for microscopic residual disease in patients with stage IIIC/IV ovarian cancer after a complete cytoreduction of their disease. PATIENTS AND METHODS: We analyzed the data of 87 consecutive patients diagnosed with stage IIIC/IV ovarian cancer operated between December 1998 and July 2011. In every patient it was possible to achieve a complete cytoreduction of their disease. (Since January 2008, our center has incorporated the use of HIPEC in patients with peritoneal surface malignancies, including patients with peritoneal dissemination of primary ovarian cancer.) RESULTS: Of 87 patients, 52 were treated with HIPEC (paclitaxel 60 mg/m(2), 60 min, 42 °C). After a univariate analysis, factors associated with lower disease-free interval were: performing a gastrointestinal anastomosis, operative time greater than 270 min, poorly differentiated histology, and not being treated with HIPEC. After multivariate analysis, independent prognostic factors included not being treated with HIPEC [hazard ratio (HR) 8.77, 95 % CI 2.76-14.42, p < 0.01] and the presence of poorly differentiated tumors (HR 1.98, 95 % CI 1.45-8.56, p < 0.05). Disease-free survival at 1 and 3 years was 66 and 18 %, respectively, in patients without HIPEC and 81 and 63 %, respectively, in patients treated with HIPEC (p < 0.01). HIPEC administration did not alter the results obtained for disease-free survival in patients with undifferentiated tumors. CONCLUSIONS: The treatment of the microscopic disease following complete cytoreduction with HIPEC in patients with advanced ovarian cancer is effective and can prolong disease-free survival. This survival benefit was not seen in undifferentiated tumors.
