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

purposeExtralevator abdominoperineal excision (ELAPE) was introduced to improve outcomes for low-lying locally advanced rectal cancers (LARC) not amenable to sphincter preserving procedures. This study investigates prospectively outcomes of patients operated on with ELAPE compared with a similar cohort of patients operated on with conventional APE.

methodsAfter the exclusion of patients without neoadjuvant therapy, in-hospital mortality, and incomplete metastatectomy, we identified 72 consecutive patients who had undergone either conventional APE (n = 36) or ELAPE (n = 36) for LARC ≤6 cm from the anal verge. The primary outcome measure was local recurrence at 5 years, and secondary outcome measures were cause-specific and overall survival.

resultsMedian distance from the anal verge was significantly lower in the ELAPE group (2 vs. 4 cm, p = 0.029). Inadvertent bowel perforation could be completely avoided in the ELAPE group, but amounted to 16.7 % in the conventional APE group (p = 0.025). Cumulative local recurrence rate at 5 years was 18.2 % in the APE group compared to 5.9 % in the ELAPE group (p = 0.153). Local recurrence without distant metastases occurred in 15.5 % in the APE group but was not observed in the ELAPE group (p = 0.039). We did not detect significant differences in cause-specific nor in overall survival.

conclusionELAPE results in lower local recurrence rates as compared with conventional APE. We conclude that the extralevator approach should be the procedure of choice for advanced low rectal cancer not amenable to sphincter preserving procedures.
