Human Epidermal Growth Factor Receptor Type 2 (HER2)-Positive Metastatic Breast Cancer With HER2-Negative Conversion: A Case Report and Treatment With Cyclin-Dependent Kinase (CDK) 4/6 Inhibitor for the Luminal Type.
Article in Cureus, 2024. 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
A 37-year-old woman was diagnosed with stage IIIA, estrogen receptor (ER)-positive/human epidermal growth factor receptor type 2 (HER2)-positive breast cancer. The patient received neoadjuvant chemotherapy with epirubicin and cyclophosphamide, followed by docetaxel, trastuzumab, and pertuzumab. The surgical specimen remained ER-positive/HER2-positive. Liver metastasis was detected after the completion of postoperative adjuvant trastuzumab and pertuzumab. A liver biopsy following treatment with trastuzumab emtansine (T-DM1) and trastuzumab deruxtecan (T-Dxd) revealed HER2-negative status. Cyclin-dependent kinase (CDK) 4/6 inhibitor combination endocrine therapy has been continued for 16 months to date while maintaining tumor shrinkage. It is essential to perform a rebiopsy during treatment to optimize therapy based on the subtype.
