Factors associated with cytoreducibility among women with ovarian carcinoma.

OBJECTIVES: The aim of the current study is to investigate the clinical and molecular factors associated with cytoreduction among women with advanced stage epithelial ovarian carcinoma EOC. METHODS: Seventy-two women with FIGO stage III and IV EOC or primary peritoneal carcinoma (PPC) underwent similar attempt at surgical cytoreduction, mostly by the same surgeon. The histologic material of these patients was reviewed and the histologic subtype and grade were assigned. Immunohistochemical tests were performed for expression of molecular regulators of apoptosis (p53, p21, Bcl(2), Bcl(x), Bax) and chemoresistance (PGP, MRP, LRP, GST). The following factors were assessed for their association with complete (no residual tumor) and optimal (residual tumor < 1 cm) cytoreduction: type of carcinoma (EOC versus PPC), stage, CA-125 values, ascites, histology, tumor grade, and p53, p21, Bcl(2), Bcl(x), Bax, PGP, MRP, LRP, GST expression using the odds ratio and associated 95% confidence intervals. Significant univariate odds ratios were assessed jointly in a multivariate logistic regression model. Receiver operating characteristic curve analysis was performed to determine the CA-125 level with the maximal cytoreduction prognostic power. RESULTS: Twenty-three (31.9%) women had no residual tumor, 35 (48.6%) had 1 cm. Factors with significant univariate associations with complete cytoreduction included stage, CA-125 level, ascites, histology, and p53. p53 expression was the only factor which remained significant in the multivariate analysis (odds ratio 7.2, 95% CI 1.5, 34.9). A preoperative CA-125 value of <or=500 IU/ml best determined complete cytoreducibility. CONCLUSIONS: Innate tumor characteristics determine cytoreducibility of women with ovarian carcinoma. Pre-operative evaluation of p53 expression may be of value in predicting the outcome of cytoreductive surgery in women with advanced stage EOC.

Health-related quality of life and cost impact of irritable bowel syndrome in a UK primary care setting.

OBJECTIVES: To identify the impact of irritable bowel syndrome (IBS) on health-related quality of life (HR-QOL), time off work and the utilisation and cost of health services. DESIGN: A case-control study was undertaken matching patients with IBS and controls. Quality-of-life information was collected using the Medical Outcomes Study 36-item Short Form (SF-36) health survey, EuroQOL instrument (EQ-5D) and IBS Quality-of-Life (IBS-QOL) instruments. Data on time off work was also collected. National Health Service (NHS) resource use in primary and secondary care was estimated by review of general practitioner (GP) and hospital records over a 12-month period. SETTING: Recruitment was from six GPs' surgeries in the Trent Region of the United Kingdom. PARTICIPANTS: 161 patients with IBS, as defined by the Rome Criteria I were recruited. These were compared with 213 controls matched for age, sex and social characteristics. MAIN OUTCOME MEASURES: SF-36 and EQ-5D scores; mean number of days off work; mean NHS costs per person during the 12-month study period. RESULTS: Patients with IBS had considerably lower HR-QOL than controls. They scored worse in all dimensions of the SF-36 and the EQ-5D and they had more time off work. On average patients with IBS cost the NHS 123 UK pounds (95% confidence interval: 35 UK pounds to 221 UK pounds, 1999 values) more per year than individuals in the control group (p = 0.04). CONCLUSIONS: IBS affects patients through reduced quality of life, more time off work and greater healthcare utilisation than a control group of patients without IBS. The difference in quality of life was pronounced and unusual in that it was influential in every dimension of both the SF-36 and the EQ-5D.
