Abstract
Background/aims: We investigated the incidences of overall and site-specific malignancies and chemopreventive effects of statin, metformin, and aspirin in patients with ulcerative colitis.
Methods: We collected data using the Health Insurance Review and Assessment claims database from January 2007 to April 2020.
Results: The overall malignancy risk among the 35,189 ulcerative colitis patients was similar to that of the general population (standardized incidence ratio, 0.94; 95% confidence interval, 0.88-1.00). In male patients, standardized incidence ratios were high for thyroid cancer and low for stomach cancer, colorectal cancer, liver cancer, and lung cancer. Concurrently, standard incidence ratios were high for liver cancer and central nervous system cancer in female patients. While 122 cases of colorectal cancer occurred in the study patients, the standardized incidence ratio was 0.83 (95% confidence interval, 0.69-0.99). Treatment for ulcerative colitis was not associated with an increased adjusted hazard ratio, while comorbidities increased it for all malignancies. Treatment for ulcerative colitis was associated with an increased adjusted hazard ratio, while comorbidities did not increase it for colorectal cancer. After adjusting for age, sex, comorbidities, and ulcerative colitis treatment, statins showed a dose-dependent chemopreventive effect for all malignancies (P=0.002), while metformin and aspirin did not show any.
Conclusions: In ulcerative colitis patients, standardized incidence ratios for all malignancies and colorectal cancer did not increase. Adjusted hazard ratios for all malignancies increased with comorbidities and those for colorectal cancer with ulcerative colitis treatment. Statins have a dose-dependent chemopreventive effect for all malignancies.
期刊介绍：
Intestinal Research (Intest Res) is the joint official publication of the Asian Organization for Crohn''s and Colitis (AOCC), Chinese Society of IBD (CSIBD), Japanese Society for IBD (JSIBD), Korean Association for the Study of Intestinal Diseases (KASID), Taiwan Society of IBD (TSIBD) and Colitis Crohn''s Foundation (India) (CCF, india). The aim of the Journal is to provide broad and in-depth analysis of intestinal diseases, especially inflammatory bowel disease, which shows increasing tendency and significance. As a Journal specialized in clinical and translational research in gastroenterology, it encompasses multiple aspects of diseases originated from the small and large intestines. The Journal also seeks to propagate and exchange useful innovations, both in ideas and in practice, within the research community. As a mode of scholarly communication, it encourages scientific investigation through the rigorous peer-review system and constitutes a qualified and continual platform for sharing studies of researchers and practitioners. Specifically, the Journal presents up-to-date coverage of medical researches on the physiology, epidemiology, pathophysiology, clinical presentations, and therapeutic interventions of the intestinal diseases. General topics of interest include inflammatory bowel disease, colon and small intestine cancer or polyp, endoscopy, irritable bowel syndrome and other motility disorders, infectious enterocolitis, intestinal tuberculosis, and so forth. The Journal publishes diverse types of academic materials such as editorials, clinical and basic reviews, original articles, case reports, letters to the editor, brief communications, perspective, statement or commentary, and images that are useful to clinicians and researchers.
