1 · What the graph read from it

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.

2 · The registry

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

We present a unique case of metastatic metaplastic breast carcinoma responding dramatically to immunochemotherapy. A 46-year-old Japanese woman with primary metaplastic carcinoma of the breast, which was immunohistochemically confirmed to be triple-negative breast cancer, underwent radical surgery, followed by adjuvant chemotherapy with an anthracycline and a taxane. Since multiple lung metastases were detected two months post-chemotherapy and the primary site was shown to be PD-L1-positive, the immune checkpoint inhibitor (ICI) pembrolizumab plus gemcitabine/carboplatin was initiated. While the treatment was discontinued after 15 days due to suspected drug-induced pneumonitis, the lung metastases significantly shrank with no development of new lesions for three months. The patient remained alive as of approximately 15 months after the recurrence date. This case highlights the potential of immunochemotherapy in treating metaplastic breast carcinomas.
