1 · What the graph read from it

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.

Abstract

backgroundA paucity of data exists in the use of neoadjuvant chemoradiation therapy (NRT) for T4, non-metastatic colon cancer. This study was conducted to determine the effect of NRT on outcomes after resection for T4 colon cancer.

methodsAll patients with non-metastatic resected clinical T4 colon cancer from 2000 to 2012 at a tertiary care center were included. The cohort was divided into two groups-those that received NRT and those that did not (non-NRT). The primary outcomes were margin-negative resection and overall survival (OS).

resultsOne hundred and thirty-one consecutive patients with non-metastatic clinical T4 colon cancer with a mean age of 65 years were included. NRT was used in 23 patients (17.4%). NRT group was noted to have non-statistically significant improvement in R0 resection rate (NRT 95.7% vs non-NRT 88.0%; p = 0.27) and local recurrence (NRT 4.3% vs non-NRT 15.7%; p = 0.15). There was a significant difference in T-stage downstaging between the two groups (NRT 30.4% vs non-NRT 6.5%; p = 0.007). In a bivariate analysis, NRT was associated with improved 5-year OS (NRT 76.4% vs non-NRT 51.5%; p = 0.03). This relationship did not persist in a Cox proportional hazard analysis that included age and comorbidity (HR 2.19; 95% CI 0.87-5.52; p = 0.09).

conclusionsThe use of NRT in locally advanced T4 colon cancer is safe and associated with increased downstaging. While there was a trend toward improvement in local recurrence and the ability to obtain margin-negative resections in the NRT group, this was not significant. Significantly improved overall survival was not observed in a multivariable analysis.
