背景：淋巴结比例（LNR）与胰腺腺癌患者的长期生存有关；然而，这在其他壶腹周围恶性肿瘤中尚未得到证实。这项研究的目的是确定LNR是否与其他壶腹周围恶性肿瘤的生存有关。方法：对1988年至2007年间522例胰十二指肠切除术（pd）的前瞻性数据库进行回顾性分析。收集临床病理资料，计算LNR。将淋巴结（LN）阳性的患者分为以下组：(1)LNR = 0；(2) LNR
BACKGROUND: Lymph node ratio (LNR) has been associated with long-term survival in patients with pancreatic adenocarcinoma; however, this has not been demonstrated in other periampullary malignancies. The put-pose of this study was to determine if LNR is associated with survival in other periampullary malignancies.METHODS: A retrospective review of a prospective database of 522 pancreaticoduodenectomies (PDs) performed between 1988 and 2007 was undertaken. Clinicopathologic data were collected, and LNR was calculated. Patients with positive lymph node (LN) status were placed into the following groups: (1) LNR = 0; (2) LNR
