Multivariable analysis for complete resection rate of 10-20 mm non-metastatic rectal neuroendocrine tumors: a retrospective clinical study

Background: This retrospective study aimed to identify key factors affecting the rate of complete resection for non-metastatic rectal neuroendocrine tumors (NETs) using both transanal local excision (TLE) and endoscopic submucosal dissection (ESD). Methods: Records in past 10 years were retrieved, a total 95 patients diagnosed with NETs sized between 10-20 mm. Treatment outcomes first compared TLE ESD significantly associated factors. Monofactor analysis was then performed resections risk factors, which subjected multivariable independent Results: depth invasion (P=0.039) complete/local (P=0.048). By monofactor resections, invasion, tumor size, stage manifestation identified be (P=0.014, 0.003, 0.002 0.028, respectively). In subsequent analysis, size odds ratio 18.838 37.223, 95% confidence interval 1.242-285.800 2.839-488.078, respectively. Conclusion: Depth that affect mm NETs.
