Complete Pathological Response to Neoadjuvant Cisplatin, Etoposide, and Pembrolizumab in Small Cell Breast Carcinoma: A Case Report and Review of the Literature.
Article in Case reports in oncology. 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
Background: Small cell breast carcinoma (SCBC) is a rare, aggressive neuroendocrine breast cancer subtype comprising less than 1% of all breast malignancies. With no standardized treatment guidelines, management is typically extrapolated from small cell lung cancer (SCLC) or triple-negative breast cancer (TNBC) protocols. Immune checkpoint inhibitors (ICIs) have shown promise in both TNBC and SCLC, but their role in SCBC remains undefined. Case Presentation: We report the case of a 65-year-old woman diagnosed with early-stage, triple-negative SCBC, exhibiting high-grade features and a Ki-67 index >90%. She received neoadjuvant cisplatin and etoposide with pembrolizumab, followed by breast-conserving surgery and adjuvant pembrolizumab. Histopathology demonstrated a complete pathological response. The patient tolerated treatment well and remains disease-free on follow-up. Conclusion: This is the first reported case of SCBC successfully treated with neoadjuvant chemoimmunotherapy, achieving complete pathological remission. It highlights the potential role of ICIs in SCBC and supports future research into biomarker-driven strategies for this rare and aggressive.
