About
Rachel Gefen is a surgical oncology researcher whose work centers on colorectal cancer management, minimally invasive surgery, and healthcare disparities. Drawing on large national datasets — particularly the National Cancer Database — she has produced landmark analyses documenting how the treatment landscape for colon and rectal cancer has evolved over the past two decades. Her most cited work, a 2022 study on rectal adenocarcinoma trends (65 citations), traced shifts in staging, treatment modalities, and survival outcomes across 16 years, offering clinicians a comprehensive benchmark for modern practice. Complementing this, her analyses of colon cancer trends and robotic versus laparoscopic colectomy have collectively accumulated over 40 citations, helping to clarify the comparative effectiveness of surgical approaches. Gefen has also pioneered the application of artificial intelligence to predict surgical conversion risk, reflecting her commitment to translating data science into practical clinical tools. Beyond technical outcomes, she has shed light on socioeconomic and racial disparities in access to robotic proctectomy and the influence of facility type on patient outcomes — work that carries important implications for health equity. Across her growing body of research, Gefen consistently demonstrates that rigorous population-level analysis can meaningfully guide surgical decision-making and improve cancer care delivery.
