Predictors of Pathologic Complete Response with Neoadjuvant Chemo-Immunotherapy in Early-Stage Triple-Negative Breast Cancer.
Article in Annals of surgical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
backgroundThe combination of pembrolizumab with neoadjuvant chemotherapy (NAC) for triple-negative breast cancer (TNBC) improves pathologic complete response (pCR) rates and event-free survival. Yet it is unclear which patients benefit most from the addition of immunotherapy. This study aims to identify predictive factors for pCR in patients with TNBC receiving chemo-immunotherapy (chemo-IO). PATIENTS AND
methodsThis single-institution retrospective analysis included 283 consecutive patients with TNBC treated with neoadjuvant chemo-IO from 1 June 2021 to 20 January 2023. The primary outcome was overall pCR; secondary outcomes were breast pCR and nodal pCR. Univariate and multivariable logistic regression models assessed for characteristics associated with overall, breast, or nodal pCR.
resultsMost patients presented with cT2 (71%) cN0 (54%) disease. The overall pCR rate was 57%, breast pCR was 58%, and axillary pCR was 67% among biopsy-proven cN+ patients. Race, pathogenic BRCA mutations, backbone chemotherapy regimen, immune-related adverse events, and disruptions in immunotherapy were not associated with pCR. Univariate associations with overall pCR were younger age (p = 0.04), lower clinical T stage (p = 0.01), ductal histology (p < 0.001), poor differentiation (p < 0.001), and unifocality (p < 0.001). Breast and axillary pCR had similar associations. Nodal pCR also had univariate associations with normal body mass index (BMI) (p = 0.04) and absence of lymphovascular invasion (LVI) (p = 0.04). On multivariable analyses, ductal histology and unifocality remained independently associated with overall and breast pCR.
conclusionsThis analysis showed few clinical variables to be independently associated with pCR after neoadjuvant chemo-IO for TNBC. Thus, predicting chemo-IO response to personalize treatment and minimize morbidity may instead lie in ongoing basic and translational research to assess for useful biomarkers.
