Implications of Homologous Recombination Deficiency for Neoadjuvant Platinum-Based Chemotherapy in Pancreatic Cancer: A Narrative Review.
Review in Annals of surgical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundPancreatic ductal adenocarcinoma (PDAC) remains a highly lethal malignancy, with a 5 year survival rate of approximately 13%. Survival is extended for the few patients who undergo surgical resection with curative intent, whereas most patients succumb to distant disease recurrence. Neoadjuvant platinum-based chemotherapy has emerged as a promising strategy to improve resectability rates and survival outcomes for PDAC patients. However, treatment-related toxicities, unpredictable clinical responses, and associated risk of tumor progression during neoadjuvant therapy may delay or preclude curative resection.As a result, predictive biomarkers are needed to identify patients most likely to benefit from neoadjuvant platinum-based chemotherapy. DISCUSSION: Alterations in the homologous recombination (HR) DNA repair pathway are reported in 3.0-19.5% of PDAC patients. These types of alterations can sensitize tumors to platinum-based chemotherapy in PDAC as well as other cancers including ovarian, colorectal, and prostate cancers. Retrospective and prospective studies in locally advanced/metastatic PDAC demonstrate higher response rates and longer survival outcomes among HR-deficient (HRD) patients receiving platinum-based chemotherapy. A growing body of evidence in the neoadjuvant setting suggests a potential benefit for HRD-PDAC patients in terms of enhanced tumor downstaging, higher resectability, and improved survival outcomes compared with HR-proficient patients. However, prospective ad hoc studies are still warranted to confirm these findings
conclusionsHomologous recombination deficiency represents a promising biomarker to guide patient selection for neoadjuvant platinum-based chemotherapy in PDAC. Incorporation of HR deficiency-testing into neoadjuvant treatment schemes will enable a more personalized therapeutic approach, supporting the implementation of precision oncology for early-stage PDAC patients.
