About

Dr. Der-Ming Chang is a leading surgical outcomes researcher whose work centers on quality-of-life (QOL) assessment in hepatocellular carcinoma (HCC) patients. His most-cited study, "Inverse Probability of Treatment Weighting in 5-Year Quality-of-Life Comparison among Three Surgical Procedures for Hepatocellular Carcinoma" (2022, 6 citations), is a landmark prospective longitudinal cohort investigation. In this work, Dr. Chang analyzed long-term changes in individual QOL subscales among 520 HCC patients following surgery, using advanced inverse probability of treatment weighting to compare outcomes across three surgical procedures. His major contribution lies in demonstrating that specific QOL predictors can effectively forecast patient well-being years after treatment, providing surgeons with evidence to tailor procedures for optimal long-term recovery. This research bridges the gap between clinical efficacy and patient-centered outcomes, offering actionable insights for shared decision-making in hepatobiliary surgery. Dr. Chang’s work has been instrumental in shifting the focus from mere survival metrics to holistic recovery, making him a key figure in surgical oncology outcomes research.
