BACKGROUND: Despite low anterior resection syndrome being a well-known consequence of sphincter-preserving rectal cancer surgery, the long-term effect on bowel function and quality of life is not fully understood. OBJECTIVE: This study aimed to elucidate whether symptoms of low anterior resection syndrome change over time and if the correlation to quality of life is equivalent when measured at 2 time points. DESIGN: This prospective cohort study included measurements at 2 time points (5 years between; range, 7.1–16.1 years from surgery to second follow-up). SETTINGS: This multicenter study included patients from Sweden and Denmark. PATIENTS: Patients were included if they were ≥18 years of age and underwent curative rectal cancer surgery with either total or partial mesorectal excision. MAIN OUTCOME MEASURES: Outcomes were measured with the low anterior resection syndrome questionnaire including a question assessing the impact of bowel function on quality of life and with the validated quality-of-life questionnaire EORTC QLQ-C30. RESULTS: In total, 282 patients were included and there were no statistically significant differences in the distribution among the 3 groups (no, minor, and major low anterior resection syndrome) when comparing time points follow-up 1 with follow-up 2 (p = 0.455). At follow-up 2, 138 patients (49%) still experienced major impairment. No both statistically and clinically significant differences were seen in the mean score of EORTC QLQ-C30 when comparing the same low anterior resection syndrome group at follow-up 1 and follow-up 2, and the impact on quality of life was comparable. Global health status/quality of life was impaired in the major low anterior resection syndrome group at both follow-up 1 (p < 0.001) and follow-up 2 (p < 0.001). LIMITATIONS: The study design prevents an evaluation of causality. CONCLUSIONS: Difficulties with low anterior resection syndrome and the impact on patients’ quality of life persist over time.

Gout patients might be at an increased risk of cancer because of obesity and heavy alcohol drinking, but uric acid has antioxidant properties, which may protect against carcinogenesis. We compared the incidence of cancer among 16 857 gout patients admitted to hospitals in Sweden during 1965-1995 with that of the national population. A total of 1425 malignant neoplasms were diagnosed in gout patients (standardized incidence ratio 1.25, 95% confidence limits 1.18, 1.31). The incidence of cancers of the oral cavity and pharynx, colon, liver and biliary tract, pancreas, lung, skin (melanoma and nonmelanoma), endometrium and kidney, as well as of malignant melanoma was increased among gout patients. With the exception of lung cancer, the risk remained elevated during the entire follow-up. This study provides no evidence of a protective effect of uric acid. Hyperuricemia may be an early manifestation of the carcinogenic process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
