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

purposeThere has been an increase in the percentage of elderly patients with colorectal cancer (CRC). However, few studies have reported the short- and long-term outcomes of laparoscopic surgery for elderly patients with CRC aged over 80 years.

methodsThis study included 529 patients who underwent laparoscopic resection for clinical stage 0-III CRC at Kobe University Hospital between January 2010 and December 2018. Propensity score matching (PSM) was used to create balanced cohorts of the elderly (aged ≥ 80, n = 113) and the non-elderly (aged < 80, n = 113). Their clinical outcomes were compared after PSM.

resultsAfter matching, carcinoembryonic antigen (CEA) level was higher in the non-elderly group, and adjuvant chemotherapy was less frequently employed in the elderly group. D3 dissection was performed more frequently and the number of the harvested lymph nodes tended to be larger in the non-elderly group. There was no significant difference in the rates of postoperative complications, reoperation within 30 days, and 30-day mortality between the groups. The 5-year relapse-free survival rate was not statistically different between the two groups (77.3% for the non-elderly vs. 62.7% for the elderly, p = 0.13). The multivariate analyses for the whole cohort showed that the factors of sex, tumor location, operation time, and conversion to open surgery, but not the age, were significant predictors of postoperative complications.

conclusionLaparoscopic surgery for colorectal cancer patients aged over 80 years is technically and oncologically safe.
