Palbociclib and endocrine therapy diminish adaptive anti-tumor immunity in early breast cancer: The NeoRHEA phase 2 study.
Trial report in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03065621 (Neoadjuvant Biomarker ResearcH Study of Palbociclib Combined With Endocrine Therapy in Estrogen Receptor Positive/HER2 Negative Breast CAncer), which is not on this map.

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.

Abstract
The NeoRHEA was a single-arm phase 2 study that included patients with estrogen receptor positive / human epidermal factor receptor 2 negative early breast cancer that received 4 cycles of neoadjuvant palbociclib and endocrine therapy. The primary outcome was baseline biomarkers of treatment resistance and secondary outcome was post-treatment transcriptional and epigenetic changes of tumor, immune and stromal cells. E2F targets and G2M checkpoint proliferation-related genes gene sets were enriched in baseline samples from resistant patients., Downregulation of E2F targets and G2M checkpoint post treatment was observed in tumor, endothelial and T cells. Gene Set Enrichment Analyses (GSEA) based on genes residing in the differentially accessible peaks revealed similar effects,. Moreover, decreases in CD8 + CD103+ tissue-resident memory cell marker genes were observed post-treatment and validated by multiplex immunohistochemistry. Our data reveal that treatment with palbociclib and endocrine therapy diminishes adaptive anti-tumor immunity by decreasing T cell proliferation and the presence of tissue-resident memory T cells NCT03065621.
