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

purposeYoung age is associated with poor prognosis in ductal carcinoma in situ (DCIS) of female breast and controversy exists regarding the optimal treatment modality for young patients. We aimed to compare treatment outcomes among breast conserving surgery (BCS), BCS with adjuvant radiotherapy (BCS + RT), and total mastectomy (MT) for young DCIS women.

methodsPubMed, Cochrane, and Embase were searched for studies reporting comparative results among BCS, BCS + RT, or MT in ≤50 years old (y/o) DCIS females. Study quality was assessed and meta-analysis with subgroup analysis was performed to pool the effect sizes of the outcomes-of-interest.

resultsWe included 3 randomized control trials and 18 observational studies. For DCIS women ≤50 y/o, RT following BCS significantly reduced the risk for ipsilateral breast tumor recurrence (IBTR) (HR = 0.66, 95% CI 0.50-0.87). However, the benefit was less robust in extremely young patients and with long follow-ups. RT revealed no statistically significant preventive effect on ipsilateral invasive recurrence (HR = 1.38, 95% CI 0.98-1.94). On the other hand, MT yielded the lowest IBTR (BCS + RT vs MT: HR = 4.4, 95% CI 2.06-9.40), both in ipsilateral DCIS recurrence and ipsilateral invasive recurrence. There was great heterogeneity and could not reach an evident conclusion concerning survival outcomes.

conclusionThis study highlighted the varying effect of RT for young DCIS females. The local control benefit of MT was definite without survival differences observed. Our study provided a moderate certainty of evidence to guide the treatment for young DCIS women. Further age-specific prospective trial is warranted.
