Unmasking Cancer Risk in Heritable PAH: The Hidden Role of BMPR2 in Epithelial Tumorigenesis.

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
backgroundBMPR2 mutations cause heritable pulmonary arterial hypertension (PAH) and may also influence epithelial carcinogenesis. CASE SUMMARY: We report 3 women with BMPR2-related PAH who developed early onset epithelial cancers: 2 breast cancers (34 and 54 years of age) and 1 colorectal cancer (47 years of age). All were on advanced PAH therapy at diagnosis. Genetic screening of relatives was negative, and additional oncogenetic testing excluded BRCA and Lynch syndrome. Management included chemotherapy, surgery in 2 cases, and palliative care in 1 case. DISCUSSION: BMPR2, essential for vascular homeostasis, is also implicated in tumor suppression and modulation of the tumor microenvironment. In our cohort of 32 patients, epithelial cancer prevalence was 9.4%, with diagnosis at significantly younger ages than the general population. These findings suggest a potential oncogenic role for BMPR2 mutations and the need for further research. TAKE-HOME MESSAGE: BMPR2 mutations may predispose to early onset epithelial cancers, warranting investigation into cancer risk and screening strategies in this population.
