The Prognostic Value of Clinical and Pathological Response to Neoadjuvant Therapy in Metastatic Renal Cell Carcinoma Undergoing Cytoreductive Nephrectomy: A Systematic Review and Clinical Implications.
Review in Cancers, 2026. 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
backgroundIn the immunotherapy era, cytoreductive nephrectomy (CN) for metastatic renal cell carcinoma (mRCC) is increasingly performed after neoadjuvant immune checkpoint inhibitor (ICI)-based therapy. Examination of the nephrectomy specimen may capture the depth of treatment-induced tumor clearance more accurately than size-based radiological criteria alone. However, pathological reporting is highly heterogeneous across studies: residual viable tumor (RVT), necrosis, pT stage, and binary downstaging have all been used, limiting reproducible cross-study comparison. We aimed to characterize this heterogeneity, assess its implications for evidence synthesis, and propose a pragmatic framework for qualitative interpretation.
methodsPRISMA-compliant systematic review of studies reporting pathological response and oncological outcomes in mRCC patients undergoing CN after neoadjuvant systemic therapy (PROSPERO CRD420251154068). A qualitative synthesis was performed. A three-category Pathological Response Category (PRC) framework is proposed to harmonize heterogeneous metrics.
resultsSeven retrospective studies (
conclusionsThe central finding of this review is not that pathological response predicts survival-which is expected-but that current pathological reporting in the mRCC surgical setting is too heterogeneous to quantify the frequency, depth, or prognostic significance of that response in a reproducible way. Prospective adoption of standardized pathological reporting protocols is the most critical next step for this field.
