Transient Regression of Breast Carcinoma After Diagnostic Biopsy and Tumor Heterogeneity: A Case Report.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Spontaneous cancer regression is a rare biological phenomenon; however, the mechanisms involved in this process are still poorly understood. We report the case of a 92-year-old woman with a histological diagnosis of breast carcinoma. On the date of the scheduled surgical resection of her tumor, she did not present the initial lesion diagnosed by biopsy, on clinical examination. The patient underwent mammography and breast magnetic resonance imaging, which confirmed the absence of the initial tumor. Due to religious beliefs, the patient refused additional specific treatment with her family's approval. In consensus with her family, we proposed imaging follow-up to assess tumor recurrence, which lasted for 18 months. In this article, we discuss the theory that the local trauma generated by the diagnostic percutaneous biopsy triggered an immune response responsible for the phenomenon of tumor regression. The secondary objective is to discuss the transformation in the histological type of tumor cell.
