The Prognostic Significance of Lymph Node Status and Lymph Node Ratio (LNR) on Survival of Right Colon Cancer Patients: a Tertiary Center Experience.
Article in Journal of gastrointestinal cancer, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundColon cancer is a major health problem and is one of the most frequent cancers all over the world. In Egypt, the incidence of colon cancer is relatively low, but its mortality rate is high. Lymphatic spread of colon cancer is one of the most important factors affecting the prognosis of patients. Recently, the lymph node ratio (LNR) has been evaluated as a prognostic parameter for survival. This study aimed at evaluation of nodal status of resected specimens and LNR, as well as its impact on the disease-free survival (DFS) and overall survival (OS) after curative resection of right colon cancer.
methodsThe institutional registry of the Oncology Center Mansoura University (OCMU) was revised for node-positive right colon cancer cases that were operated in the period between January 2010 and January 2015. Fifty-three patients met the inclusion criteria and were followed up till January 2020.
resultsA total of 766 lymph nodes were excised from the patients. Thirty-two patients (60.4%) had a LN yield of ≥12 LNs with a mean LNR of 0.257 ± 0.27. Multivariate analysis of outcomes showed that LNR was significantly correlated with both DFS (p = 0.015) and OS (p = 0.024). Moreover, the number of resected LNs was also associated with statistically significant relationship with the DFS and OS.
conclusionOur study confirms the validity of LNR as a prognostic tool that correlates with the survival of patients. Moreover, LNR cutoff values may help predict those of high chance of tumor recurrence.
