chemosensitivity

Full Definition

The susceptibility of malignant cells to destruction by chemotherapeutic agents, which varies significantly among different cancer types, individual patients, and even within the same tumor over time. In gynecologic oncology, chemosensitivity assessment helps guide treatment decisions, particularly in recurrent disease where prior response patterns inform subsequent therapy choices. Factors influencing chemosensitivity include tumor biology, genetic markers, previous treatment history, and treatment-free intervals.

Usage

Usage note: Often used in contrast with chemoresistance; ensure clear distinction in clinical documentation.
