Validation of the postoperative prognostication tool PREDICT version 2.2 and 3.0 using data from the National cancer center hospital in Japan
This study validates PREDICT v2.2 and v3.0, prognostic tools for breast cancer survival, using data from 2,980 Japanese patients. Both versions underestimated survival but v3.0 showed improved calibration. Both maintained good discriminative performance (AUC > 0.80). The findings suggest general applicability for Japanese patients, with v3.0 being more suitable for shared decision-making due to better calibration.
EXECUTIVE IMPACT
The PREDICT tool, a prognostic model developed in the UK for breast cancer patients, was evaluated for its generalizability in a Japanese cohort. The study specifically compared versions 2.2 and 3.0 using data from 2,980 patients at the National Cancer Center Hospital in Japan. While both versions tended to underestimate overall survival, version 3.0 demonstrated significantly improved calibration, making it more reliable for direct communication of prognostic estimates. Both versions maintained strong discriminative performance over a 10-year period. These results highlight PREDICT's value for Japanese patients, advocating for v3.0 in shared decision-making due to its enhanced calibration, while acknowledging v2.2's slightly better discrimination for risk stratification.

Impact on Japanese Breast Cancer Prognosis
This study provides crucial validation of PREDICT in a Japanese cohort, addressing a previous gap in regional efficacy assessment. While both versions performed adequately, v3.0's enhanced calibration is particularly significant for shared decision-making in a population with distinct epidemiological and biological characteristics.
Outcome: Improved confidence in applying PREDICT v3.0 for personalized prognostic communication, with ongoing considerations for regional factor integration and future AI model development.
