Abstract
Purpose: We designed this study to evaluate the relationship between radiation proctopathy (RP) and the risk of colon and rectal cancer in prostate cancer patients.
Methods: This is a retrospective cohort study evaluating patients with prostate cancer who received pelvic radiation therapy between January 2004 and January 2024. The study aims to compare the incidence of post-radiation rectal and colon cancer between patients who developed RP and patients who did not. We excluded patients with a previous history of colon cancer, colectomy, or inflammatory bowel disease.
Results: In total, 12,629 met the inclusion criteria, 533 patients were diagnosed with RP, and 12,096 were without. We observed a higher incidence of colorectal cancer (3.75% vs. 0.63%), colon cancer (2.06% vs 0.40%), and rectal cancer (1.69% vs 0.23%) in patients with RP compared to those without PR (p < 0.001) during the follow-up period of 81 months for the RP group and 68 months for the non-RP group. PR was associated with colon and rectal cancer with an HR of 4.43 (95% CI, 2.29-8.57; p < 0.0001) and 7.27 (95% CI, 3.43-15.43; p < 0.0001), respectively.
Conclusions: RP is an independent risk factor for developing rectal and colon cancer after pelvic radiation therapy in patients with prostate cancer.
期刊介绍：
The Journal of Gastrointestinal Cancer is a multidisciplinary medium for the publication of novel research pertaining to cancers arising from the gastrointestinal tract.The journal is dedicated to the most rapid publication possible.The journal publishes papers in all relevant fields, emphasizing those studies that are helpful in understanding and treating cancers affecting the esophagus, stomach, liver, gallbladder and biliary tree, pancreas, small bowel, large bowel, rectum, and anus. In addition, the Journal of Gastrointestinal Cancer publishes basic and translational scientific information from studies providing insight into the etiology and progression of cancers affecting these organs. New insights are provided from diverse areas of research such as studies exploring pre-neoplastic states, risk factors, epidemiology, genetics, preclinical therapeutics, surgery, radiation therapy, novel medical therapeutics, clinical trials, and outcome studies.In addition to reports of original clinical and experimental studies, the journal also publishes: case reports, state-of-the-art reviews on topics of immediate interest or importance; invited articles analyzing particular areas of pancreatic research and knowledge; perspectives in which critical evaluation and conflicting opinions about current topics may be expressed; meeting highlights that summarize important points presented at recent meetings; abstracts of symposia and conferences; book reviews; hypotheses; Letters to the Editors; and other items of special interest, including:Complex Cases in GI Oncology: This is a new initiative to provide a forum to review and discuss the history and management of complex and involved gastrointestinal oncology cases. The format will be similar to a teaching case conference where a case vignette is presented and is followed by a series of questions and discussion points. A brief reference list supporting the points made in discussion would be expected.
