背景资料：检查12个或更多的区域淋巴结（LN）是结肠癌淋巴结分期的最低标准，并可作为充分切除的替代指标。目的：确定医院在LN检索数量中的贡献作用。设计/设置：我们回顾性分析了83例患者的结肠切除术，由2名外科肿瘤学家在国家综合癌症网络（NCCN）医院或社区进行，患者：我们纳入了所有因原发性结肠癌行结肠切除术的患者，排除了复发、直肠癌或术前化疗的患者。结果：NCCN医院与社区医院检查淋巴结的中位数分别为17.8例和7.0例（P
Background: Examination of 12 or more regional lymph nodes (LNs) is the accepted minimum for nodal staging in colon cancer and serves as a surrogate for adequate resection.Objective: To determine the contributing role of the hospital in the number of LNs retrieved.Design/Setting: We retrospectively reviewed colon resections in 83 patients by 2 surgical oncologists at a National Comprehensive Cancer Network (NCCN) hospital or at community-based hospitals from January 1, 2002, through December 31, 2007.Patients: We included all patients undergoing colectomy for primary colon cancer and excluded patients with recurrence, rectal cancer, or preoperative chemotherapy.Main Outcome Measures: Total number of LNs retrieved. We also analyzed clinical factors accounting for differences.Results: The median number of LNs examined at the NCCN hospital (42 patients) vs the community hospitals (41 patients) were 17.8 vs 7.0 (P
