Significance of homologous recombinant deficiency as a biomarker for drug sensitivity in colorectal cancer.
Article in British journal of cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 (CRC) is a substantial global health concern due to its limited treatment options, especially for oxaliplatin (L-OHP) regimen resistance. This study used organoid-based screening methodologies to evaluate drug responses in CRC while validating the approach with patient-derived CRC organoids and investigating potential biomarkers.
methodsPatient-derived organoids were created from CRC surgical specimens, and drug screening were performed. Selected organoids with high and low L-OHP sensitivity underwent next-generation sequencing (NGS), and in vivo experiments using xenotransplantation were used to validate in vitro results. Moreover, the clinical application of homologous recombination deficiency (HRD) as a biomarker was investigated.
resultsOrganoid drug screening revealed differences in L-OHP sensitivity among 34 patient-derived CRC organoids, and NGS deemed HRD as a potential biomarker. In vivo experiments validated the correlation between HRD status and L-OHP sensitivity, and clinical data suggested the potential of HRD as a biomarker for recurrence-free survival in patients treated with L-OHP. Additionally, HRD exhibited potential as a biomarker for other platinum agents and poly (ADP-ribose) polymerase inhibitors in CRC.
conclusionsThe study underscores HRD as a potential biomarker for predicting L-OHP sensitivity, expanding its application to other drugs in CRC. Organoid screening is reliable, providing insights into the intricate association between genetic features and treatment responses.
