pathological staging
Definitive tumor staging based on histopathological examination of surgically resected specimens, providing the most accurate prognostic information.
Full Definition
Pathological staging represents the gold standard for cancer staging, incorporating detailed examination of the surgical specimen including primary tumor characteristics, lymph node involvement, and margin status. This post-surgical assessment often differs from clinical staging, as it provides direct visualization of tumor extent, accurate lymph node counts, and precise measurement of tumor invasion depth. Pathological staging forms the foundation for adjuvant treatment decisions, prognostic counseling, and clinical trial enrollment, as it offers the most accurate assessment of disease extent and cancer biology.
Usage
Usage note: Considered more accurate than clinical staging for prognosis.
