摘要
目的：评估腹膜反射受累与直肠癌患者长期肿瘤预后的相关性。方法：前瞻性观察研究，来自一个专门的结直肠单位，包括连续一系列接受直肠癌肠系膜切除术的患者。病理检查采用Shepherd分级法评价腹膜反射（PR）受累情况。评估总生存期（OS）、无病生存期（DFS）和局部复发（LR）。结果：160例患者纳入本分析。在85例高于或低于PR水平的肿瘤中，有28.2%的肿瘤累及腹膜。肿瘤高度位置不同，OS、DFS或LR无差异。累及PR的肿瘤5年OS、DFS和LR分别为58.3%、61.7%和30.3%。累及腹膜的患者LR率较高（p = 0.02）， OS较短（p = 0.04）。Shepherd 4级腹膜受累是OS的独立危险因素(HR 2.9；95% CI 1.1-9.5, p = 0.04)和LR (HR 4.2；95% CI 1.2 ~ 16.9, p = 0.04)。结论：直肠癌切除术后腹膜受累是局部复发和生存差的独立危险因素。
Peritoneal reflection involvement as a prognostic factor in rectal cancer. Long-term oncological outcomes from a prospective study.
Purpose: To assess the relevance of peritoneal reflection involvement in long-term oncological outcomes in patients with rectal cancer.
Methods: Prospective observational study from a specialized colorectal unit that included a consecutive series of patients undergoing mesorectal excision for rectal cancer. Peritoneal reflection (PR) involvement was evaluated on pathological examination using Shepherd's classification. Overall survival (OS), disease-free survival (DFS), and local recurrence (LR) were assessed.
Results: One hundred sixty patients were included in the present analysis. Peritoneal involvement was present in 28.2% of the 85 tumors above or at the level of PR. There were no differences in OS, DFS, or LR according to tumor's height location. The 5-year OS, DFS, and LR for tumors involving PR were 58.3%, 61.7%, and 30.3%, respectively. Patients with peritoneal involvement had a higher LR rate (p = 0.02) and shorter OS (p = 0.04). Shepherd's grade 4 peritoneal involvement was an independent risk factor for OS (HR 2.9; 95% CI 1.1-9.5, p = 0.04) and LR (HR 4.2; 95% CI 1.2-16.9, p = 0.04).
Conclusion: After rectal cancer resection, peritoneal involvement is an independent risk factor for local recurrence and poor survival.
期刊介绍：
The International Journal of Colorectal Disease, Clinical and Molecular Gastroenterology and Surgery aims to publish novel and state-of-the-art papers which deal with the physiology and pathophysiology of diseases involving the entire gastrointestinal tract. In addition to original research articles, the following categories will be included: reviews (usually commissioned but may also be submitted), case reports, letters to the editor, and protocols on clinical studies.
The journal offers its readers an interdisciplinary forum for clinical science and molecular research related to gastrointestinal disease.
