Patient reported outcomes after risk-reducing surgery in patients at increased risk of ovarian cancer.

OBJECTIVE: To describe the quality of life of women at an increased risk of ovarian cancer undergoing risk-reducing bilateral salpingo-oophorectomy (RRBSO). METHODS: Patients evaluated in our gynecologic oncology ambulatory practice between January 2018-December 2019 for an increased risk of ovarian cancer were included. Patients received the EORTC QLQ-C30 and PROMIS emotional and instrumental support questionnaires along with a disease-specific measure (PROM). First and last and pre- and post-surgical PROM responses in each group were compared as were PROMs between at-risk patients and patients with other ovarian diseases. RESULTS: 195 patients with an increased risk of ovarian cancer were identified, 155 completed PROMs (79.5%). BRCA1 or BRCA2 mutations were noted in 52.8%. Also included were 469 patients with benign ovarian disease and 455 with ovarian neoplasms. Seventy-two at-risk patients (46.5%) had surgery and 36 had both pre- and post-operative PROMs. Post-operatively, these patients reported significantly less tension (p = 0.011) and health-related worry (p = 0.021) but also decreased levels of health (p = 0.018) and quality of life <7d (0.001), less interest in sex (p = 0.014) and feeling less physically attractive (p = 0.046). No differences in body image or physical/sexual health were noted in at-risk patients who did not have surgery. When compared to patients with ovarian neoplasms, at-risk patients reported lower levels of disease-related life interference and treatment burden, less worry, and better overall health. CONCLUSIONS: In patients with an increased risk of ovarian cancer, RRBSO is associated with decreased health-related worry and tension, increased sexual dysfunction and poorer short-term quality of life. Patients with ovarian neoplasms suffer to a greater extent than at-risk patients and report higher levels of treatment burden and disease-related anxiety.

Outcomes following percutaneous upper gastrointestinal decompressive tube placement for malignant bowel obstruction in ovarian cancer.

OBJECTIVE: The objective of this study was to evaluate peri-operative and survival outcomes of ovarian cancer patients undergoing percutaneous upper gastrointestinal decompression for malignant bowel obstruction (MBO). METHODS: Retrospective chart review was used to identify patients with ovarian, peritoneal, or fallopian tube cancer who underwent palliative decompressive treatment for MBO from 1/2002 to 12/2010. Kaplan-Meier methods were used to estimate the median survival (MS) and multivariate analysis used to determine if any variables were associated with the hazard of death. RESULTS: Fifty-three patients met inclusion criteria. Median length of diagnosis prior to intervention was 21 months. Fifteen (28.3%) patients experienced complications and 9 required revision. Forty-nine (92.5%) experienced relief of symptoms after placement, and 91% tolerated some form of oral intake. Following placement, 19 (36%) patients received additional chemotherapy and 21(41%) patients received total parental nutrition (TPN). Thirty-five patients were discharged home/outpatient facility, 16 to hospice care, and 2 died prior to discharge. MS for all patients was 46 days. Patients who received chemotherapy had a MS of 169 days compared to 33 days (p<0.001). We failed to find an association between survival and TPN or performance status. CONCLUSIONS: Malignant bowel obstruction is a common complication of ovarian cancer. Management is palliative; risks and benefits of any therapy must be considered. Percutaneous decompressive therapy provides relief from associated symptoms, and allows patients to be discharged home. Median survival in this group is limited, and decisions regarding aggressive therapy should be individualized.

Effect of chemotherapy delays and dose reductions on progression free and overall survival in the treatment of epithelial ovarian cancer.

INTRODUCTION: Hematologic, gastrointestinal, and neurologic complications are common side effects of the platinum and taxane-based chemotherapy used in the primary treatment of epithelial ovarian cancer (EOC). These side effects and the impact of the resultant chemotherapy dose modification on disease free interval have not been extensively studied. The goal of this study was to determine the effect of chemotherapy delays and dose reductions on progression free survival (PFS) and overall survival (OS). METHODS: A review of patients with primary epithelial ovarian, peritoneal, and fallopian tube carcinoma treated between 1/2000 and 12/2007 was performed. Inclusion criteria were advanced stage disease and first line chemotherapy with a platinum and taxane regimen. Cox proportional hazard models were used to determine the effect of chemotherapy reductions and delays on PFS and OS. RESULTS: One hundred and fifty seven patients met the inclusion criteria. Patients were divided into four groups: no delays or reductions (48%), delay only (27%), reduction only (8%), and both delay and reduction (18%). The mean number of delays/reductions per patient was 1.1 (range=0-5) and therapy was delayed a mean of 8 days. The most common reasons for delays/reductions were neutropenia (n=51), thrombocytopenia (n=45), and neuropathy (n=18). There were no differences detected in PFS or OS between groups. CONCLUSIONS: There were no differences detected in survival between patients who required dose adjustments and treatment delays and those who did not. The lack of association between survival and chemotherapy alterations suggests that in specific circumstances patients with advanced ovarian cancer should have individualized treatment plans.

What is the optimal goal of primary cytoreductive surgery for bulky stage IIIC epithelial ovarian carcinoma (EOC)?

OBJECTIVE: Recent studies have suggested that the definition of optimal cytoreduction for advanced EOC should be changed from the current Gynecologic Oncology Group threshold of < or =1 cm residual disease to no gross residual disease owing to improved survival of patients (pts) rendered macroscopically disease-free. The objective of this study was to analyze survival rates at very specific residual disease diameters to determine the optimal goal of primary cytoreduction for bulky stage IIIC EOC. METHODS: A prospectively kept database was used to identify and review the records of all pts with Stage IIIC EOC who underwent primary cytoreductive surgery at our institution between January 1989 and December 2003. To analyze a homogeneous cohort of cases, we excluded pts with stage IIIC disease based on nodal metastasis alone (without bulky abdominal tumor), fallopian tube or primary peritoneal carcinomas, and borderline tumors. Standard statistical analyses were utilized. RESULTS: The study cohort included 465 pts. The median age was 60 years (range, 25-87), and the median follow-up was 38 months (range, 1-199). Univariate and multivariate analyses, which included various prognostic factors, identified amount of residual disease as a significant prognostic factor (P < 0.001). Median overall survival in relation to the 5 residual disease categories was: no gross residual, 106 months; gross < or =0.5 cm, 66 months; 0.6-1.0 cm, 48 months; 1-2 cm, 33 months; >2 cm, 34 months. Statistical comparison between the 5 residual disease categories revealed 3 distinct groups with significantly different survival rates (P < 0.01). These 3 groups were: (1) no gross residual; (2) gross < or =1 cm residual; and (3) >1 cm residual. Although the difference in survival did not reach statistical significance, within the gross < or =1 cm residual group, there was a trend toward improved survival in pts left with smaller volume, < or =0.5 cm residual compared with those with 0.6-1.0 cm residual (P = 0.06). CONCLUSION: Our data suggest that removal of all evidence of macroscopic disease is associated with prolonged survival and should be the goal of primary cytoreductive surgery. If complete gross resection is not feasible, however, cytoreduction to as minimal residual tumor as possible should be the focus of cytoreductive efforts, as each incremental decrease in residual disease below 1 cm may be associated with an incremental improvement in overall survival.
