Efficacy and safety of radiotherapy in patients with microsatellite stable or proficient mismatch repair colorectal cancer liver metastasis.

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
backgroundColorectal cancer is one of the malignant tumors with a high incidence and mortality rate globally, and the occurrence of liver metastasis significantly affects patient survival prognosis. In recent years, the application of immune checkpoint inhibitors (ICIs) in cancer treatment has made important progress, especially showing good therapeutic effects in patients with high microsatellite instability or mismatch repair deficiency. However, for the majority of patients with microsatellite stable (MSS) or proficient mismatch repair (pMMR) colorectal cancer, the efficacy of ICIs is limited, prompting researchers to explore combination therapy strategies to improve efficacy. Targeted drugs such as tyrosine kinase inhibitors (TKIs) and radiotherapy are believed to work synergistically with ICIs by modifying the tumor microenvironment and enhancing antigen presentation.
aimTo investigate the efficacy and safety of the combination therapy of radiotherapy, ICIs, and TKIs in patients with MSS or pMMR colorectal cancer liver metastasis (CCLM), in order to provide new clinical treatment references.
methodsA retrospective analysis was conducted on the clinical data of 43 MSS or pMMR CCLM patients treated at our hospital from September 2021 to July 2024. Based on the treatment interventions received, the patients were divided into a control group (
resultsThe disease control rate in the observation group (63.64%) was significantly higher than that of the control group (23.81%) (
conclusionCompared to the ICIs and TKIs combination therapy, the radiotherapy, ICIs, and TKIs triple therapy can further improve the disease control rate and serum tumor marker levels in MSS or pMMR CCLM patients without increasing the risk of related adverse reactions, making it a treatment regimen worthy of further validation.
