Prognostic role of the lymph node ratio in node positive colorectal cancer: a meta-analysis
The lymph node ratio (LNR) (i.e. the number of metastatic lymph nodes divided by the number of totally resected lymph nodes) has recently emerged as an important prognostic factor in colorectal cancer (CRC). However, the tumor node metastasis (TNM) staging system for colorectal cancer does not consider it as a prognostic parameter. Therefore, we conducted a meta-analysis to evaluate the prognos...
متن کاملLymph Node Ratio for Nodal Staging in Colorectal Cancer - a Promising, but Premature Tool
10-14 regional lymph nodes, nodal staging in stage III colorectal cancer, which is solely based on the number of metastatic lymph nodes, would be inaccurate in certain circumstances. Recently, the metastatic lymph-node ratio has been suggested as an alternative tool for nodal staging in stage III colorectal cancer [2-4]. Also, after preoperative chemoradiation therapy in rectal cancer patients,...
متن کاملImpact of lymph node ratio in the colorectal cancer staging system.
AIM Some researchers have proposed the Lymph Node Ratio (LNR) as a prognostic index for post-surgical colorectal cancer follow up. MATERIAL AND METHOD Two hundred patients with colorectal cancer (ratio F/M of 2:1) were studied. Patients were divided in subgroups according to N-stage and LNR score, subgroups of LNR were made on quartiles. For each subgroup 5 year survival rate was calculated a...
متن کاملNegative to positive lymph node ratio is a superior predictor than traditional lymph node status in stage III colorectal cancer
Negative lymph node counts has recently attracted attention as a prognostic indicator in colorectal cancer (CRC). But little is known about prognostic significance of negative to positive lymph node ratio (NPR) in CRC. Our aim was to determine impact of NPR on oncological outcomes in patients with stage III CRC. This retrospective study included 2,256 patients with stage III CRC under curative ...
متن کاملPrognostic Value of Lymph Node Ratio in comparison to Lymph Node Metastases in Stage III Colon Cancer
Background & Objectives: Colon cancer is currently of high incidence and mortality rate. Identifying the factors influencing its prognosis can be very beneficial to its clinical treatment. Recent studies have shown that lymph nodes ratio can be considered as an important prognostic factor. The aim of the present study is to investigate the effect of this factor on the prognosis of the ...
