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

purposeRadiotherapy for ductal carcinoma (DCIS) is increasing, but the risks and benefits of the treatment remain uncertain. We aimed to investigate the relationship between radiotherapy for DCIS and risk of second non-breast cancers in a large US cohort.

methodsWe conducted a retrospective cohort study of 52,556 women in 12 U.S. population-based cancer registries diagnosed with first primary DCIS during 1992-2008 at age 25-79 years. We estimated relative risks (RRs), attributable risks (AR), and excess absolute risks (EAR) of second non-breast cancers associated with radiotherapy using Poisson regression adjusted for age at year of diagnosis, grade, hormonal therapy (yes/no or unknown), and time since diagnosis.

resultsApproximately half of the women (46.3%) received radiotherapy. Radiotherapy was associated with an increased risk of all second non-breast cancers combined [RR 1.17, 95% confidence interval (CI) 1.08-1.28] and all in-field, radiation-related second cancers combined (RR 1.37, 95% CI 1.15-1.63), driven by second lung cancers (RR 1.33, 95% CI 1.10-1.60) and non-CLL leukemia (RR 1.71, 95% CI 1.02-2.86). The estimated cumulative excess risk of all second non-breast cancers was 0.8% by 15 years after DCIS diagnosis.

conclusionsRadiotherapy was associated with an increased risk of second non-breast cancers. The specific excess of cancers at sites likely in/near the radiotherapy field suggests the findings are unlikely due exclusively to confounding, but further research into factors related to receipt of radiotherapy is needed. Our risk estimates can be used to help assess the balance of the risks and benefits of radiotherapy for DCIS and to inform clinical practice.
