Impact of the Tumor Microenvironment and Molecular Oncology in Peritoneal Metastases.
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
BACKGROUND/
objectivesPeritoneal metastases (PMs) arise from gastrointestinal, gynecologic, hepatobiliary, and colorectal origins and are associated with poor outcomes. Cytoreductive surgery (CRS) with intraperitoneal (IP) chemotherapy offers benefit for select patients, but survival remains limited. This review aims to summarize recent insights into the molecular and tumor microenvironmental (TME) changes characteristic of PMs and the impact of IP chemotherapy.
methodsA literature review was performed using recent clinical, translational, and preclinical studies examining alterations in molecular signaling, DNA repair alterations, metabolic pathways, and angiogenic factors in PMs before and after IP therapy.
resultsPeritoneal metastases exhibit distinct biology after being treated with IP chemotherapy. Treatment induces alterations in gene expression, mutational patterns, and immune infiltrates. Heated intraperitoneal chemotherapy (HIPEC) has been associated with increased CD8+ T-cell activity, macrophage and NK cell shifts, and modulation of PD-1/PD-L1 signaling, which correlate with treatment response and survival. Emerging data on PIPAC similarly suggests induction of favorable gene expression changes with repeated treatment, though supporting evidence remains more limited than for HIPEC. Angiogenic pathways-particularly VEGF and HIF1α-remain key drivers of PM progression and predictors of post-operative outcomes. Early findings suggest potential synergy between IP chemotherapy and immunotherapy though clinical trials are ongoing.
conclusionsIP chemotherapy induces tumor microenvironmental changes that have potential to shape therapeutic response. Characterizing these measurable biologic changes may allow clinicians to improve patient selection and support the development of combination therapies to enhance outcomes.
