About
Chi Chih Lien is a leading urologic surgeon and researcher whose work centers on advancing robot-assisted partial nephrectomy (RaPN) for renal cell carcinoma (RCC). His primary research focus is the refinement of nephrometry scoring systems—specifically the Diameter-Axial-Polar (DAP) score—to better predict long-term surgical, oncological, and functional outcomes. In his landmark 2020 study, Lien systematically compared the predictive value of the DAP score against the established RENAL score for “trifecta” outcomes (a composite of negative margins, minimal renal function loss, and no complications) in RaPN. This work provides critical evidence that DAP scoring may offer superior stratification for complex kidney tumors, helping surgeons select optimal candidates for nephron-sparing surgery. While his most-cited paper has garnered 2 citations to date, its clinical significance lies in its potential to standardize preoperative planning and improve patient counseling. Lien’s contributions are particularly valuable for surgeons seeking to maximize renal function preservation while maintaining oncologic control—a key challenge in modern urologic oncology. His research continues to shape how nephrometry is applied in robotic surgery.
