performance status
Standardized measure of a patient's functional capacity and ability to tolerate cancer treatment.
Full Definition
Performance status is a crucial assessment tool in urologic oncology that quantifies a patient's general well-being and functional capacity to carry out daily activities and tolerate cancer treatment. The most commonly used scales are the Eastern Cooperative Oncology Group (ECOG) Performance Status (0-4) and the Karnofsky Performance Scale (0-100). Performance status strongly influences treatment decisions, prognosis, and eligibility for clinical trials. A declining performance status may indicate disease progression or treatment toxicity and often necessitates adjustment of therapeutic plans. In urologic oncology, performance status is particularly important when considering aggressive treatments like cytoreductive surgery or intensive chemotherapy regimens.
Usage
Usage note: Two words, not hyphenated. ECOG and Karnofsky are proper names and should be capitalized.
