Complete Response of Triple-Negative Metaplastic Carcinoma of the Breast Using Pembrolizumab.
Article in Case reports in oncology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Metaplastic breast cancer (MpBC) is a rare form of breast malignancy with a poor prognosis and limited treatment guidance. Here, we report on a case of triple-negative MpBC that was successfully treated following the Keynote-522 clinical algorithm using pembrolizumab, paclitaxel, carboplatin, adriamycin, and cyclophosphamide in a neo-adjuvant fashion. The radiographic and histologic findings of the tumor are reviewed here along with the treatment regimen and response. No major toxicities associated with pembrolizumab were observed in this case. This case report serves as an example of complete pathological response of triple-negative MpBC with pembrolizumab plus chemotherapy and demonstrates the need for further research on chemoimmunotherapy for MpBC.
