Patient-reported Outcomes After Routine Treatment of In Situ/Atypical Lesions: The PORTAL Study.
Article in Annals of surgical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundGuideline concordant care (GCC) for ductal carcinoma in situ (DCIS) includes some combination of surgery, radiation, and/or endocrine treatment. Active monitoring (AM) is a common approach for high-risk breast histologies (e.g., atypical ductal hyperplasia [ADH] lobular intraepithelial neoplasias [LIN]) and has been proposed as an alternative to GCC for some low-risk DCIS. We compared patient-reported outcomes in women with DCIS who received GCC with those with other high-risk breast histologies in an active monitoring-proxy group (AM-P).
methodsWomen diagnosed with DCIS (GCC) or ADH/LIN (AM-P) from 2012 to 2017 at four cancer centers were surveyed regarding surgical-area pain, severity, and burden, generalized pain, anxiety, depression, and quality of life (QOL). The primary comparison was GCC versus AM-P. Multivariable logistic regression was used to model odds of reporting surgical-area pain. Multivariable marginal zero-inflated negative binomial models estimated mean scores and differences by group.
resultsA total of 912 women completed the survey (GCC, n = 538; AM-P, n = 374). At a median of 45.4 months following diagnosis, the AM-P group had lower odds of pain in the past month (0.35, 95% CI 0.25-0.49) and clinically significant pain (0.43, 95% CI 0.28-0.68). Adjusted mean pain severity index, surgical area sensory disturbance, pain-related cognitive/emotional impact scores were lower in the AM-P versus GCC group. Generalized pain, QOL, anxiety, and depressive symptoms were similar between groups.
conclusionsWomen with DCIS treated with GCC experienced more breast/chest wall pain than women in the AM-P group, although QOL was similar. Understanding these trade-offs can inform surgical de-escalation for high-risk lesions, including low-risk DCIS.
