Radiation-Associated Angiosarcoma of the Breast: A Case Report with Review of Reported Cases in Japan.
Article in Surgical case reports, 2026. 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
introductionRadiation-associated angiosarcoma of the breast (RAASB) is an extremely rare but serious complication that can occur several years after breast-conserving surgery and adjuvant radiotherapy. Owing to its rarity and nonspecific cutaneous manifestations, the diagnosis of RAASB is often delayed. There is no established treatment for RAASB, and its prognosis remains poor. CASE PRESENTATION: A 63-year-old woman developed progressive breast edema 14 years after breast-conserving surgery with axillary lymph node dissection and adjuvant radiotherapy for invasive ductal carcinoma. Two years later, she presented with breast masses with purpura and biopsy-confirmed angiosarcoma. Wide mastectomy with skin grafting was performed, followed by weekly administration of adjuvant paclitaxel. The patient remained recurrence-free for 12 months postoperatively.
conclusionsRAASB can develop long after breast-conserving therapy and may be preceded by subtle skin changes or persistent breast edema. Long-term follow-up and patient education are essential for patients who have undergone breast irradiation. Early imaging or biopsy should be considered when breast lymphedema is observed.
