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.

2 · The registry

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

aimRates of local recurrence (LR) after transanal endoscopic microsurgery (TEM) for rectal carcinoma vary; the reasons remain unclear. We analyzed LR after TEM for low-risk pT1 (G1/2/X, L0/X) rectal carcinoma to investigate the influence of completeness of resection and occult lymph node metastasis on risk of LR.

methodLR location and stage, completeness of resection of primary carcinoma (minimal distance between tumor and resection line ≤1 mm vs >1 mm), and incidence of involved lymph nodes in resected LR specimens were collected, and tumor characteristics of LR were compared with primary carcinoma. Distant metastasis and overall and cancer-specific survival were determined.

resultsLR developed in 14 patients; in 2/4 with R1/X resection, in 3/8 (38%) with clear margins (R0) but a minimal distance of ≤1 mm, and in 9/88 (10%) with formally complete resection. Six of nine patients with formally complete resection underwent radical surgery for LR; in five out of these six, lymph nodes were not involved. In 5/14 patients, LR was poorly differentiated compared to primary carcinoma. Main LR causes were incomplete tumor resection or tumor persistence after formally complete resection. Overall (p = 0.008) and cancer-specific (p < 0.001) survival was lower in LR patients compared to non-LR patients, even if lymph nodes were uninvolved.

conclusionsThe results suggest that most LRs after TEM for low-risk rectal cancer were caused by residual tumor at the previous excision site and not by undetected lymph node metastases. By improved standardization of surgical techniques to ensure complete resection of carcinomas and thorough pathological assessments, most LRs seem to be avoidable.
