About

Ethna Mannion is a urological researcher whose work focuses on refining risk stratification and prognostic accuracy in prostate cancer, particularly for high-risk disease. Her major contribution lies in investigating whether tumour volume can serve as an independent predictor of outcomes following radical prostatectomy, challenging the current reliance on PSA, ISUP grade group, and multiparametric MRI. Her most-cited study, published in 2021, analyzed data from high-risk patients and demonstrated that tumour volume may offer additional prognostic value beyond traditional staging tools, potentially guiding more personalized treatment decisions. With 7 citations, this work has already sparked discussion in the urological oncology community, highlighting the need to incorporate volumetric assessment into routine clinical practice. Mannion’s research bridges a critical gap between solid tumour oncology and prostate cancer management, where crude estimates like maximum cancer core length currently prevail. Her findings advocate for a paradigm shift, encouraging clinicians to consider tumour volume as a standard metric. For students and researchers, Mannion’s work exemplifies how revisiting established parameters can uncover novel insights, ultimately aiming to improve surgical planning and patient outcomes in high-risk prostate cancer.
