Colorectal Leiomyosarcoma: Demographics Patterns, Treatment Characteristics, and Survival Analysis in the U.S. Population.
Background: Colorectal leiomyosarcoma (CR-LMS) is a rare neoplasm arising from smooth muscle cells. It accounts for less than 0.1% of all colorectal malignancies. In this population-based study, we aim to understand the demographics, treatment characteristics, and pathologic factors associated with survival in CR-LMS.
Methods: Data from the SEER Program (2000-2018) were analyzed using SEER*Stat and SPSS. Statistical methods included descriptive analysis, Kaplan-Meier survival curves, log-rank tests, and Cox proportional hazards regression to assess the impact of various factors on disease-specific and overall survival.
Results: A total of 191 cases of CR-LMS were identified. Most patients were 60-69 years of age (median: 64 years) and Caucasian (78%). There was nearly the same distribution in sex (M:F ratio; 1:1.2). The overall 5-year observed survival was 50.3% (95% C.I., 46.3-54.2). The 5-year disease-specific survival (DSS) was 66.1% (95% C.I., 62.0-70.1). The 5-year overall survival after resection was 60.8% (95% C.I., 56.3-65.3). Multivariable analysis identified grades III and IV (p = 0.028) as negative predictors of overall survival. Regional spread and distant stage are negative predictors of overall survival (p < 0.01).
Conclusion: Our data reveals that colorectal leiomyosarcoma (CR-LMS) often presents in patients around 64 years old with advanced stages and poor differentiation. Key adverse prognostic factors include older age, high tumor grade, large tumor size, and distant metastases, with surgical resection showing the best survival outcomes. To improve outcomes, further research and consolidation of data are essential for developing targeted therapies and comprehensive guidelines.
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.
