Evidence acquired before treatment, supplemented or modified by the additional evidence acquired during and from surgery, particularly from pathologic examination of the resected specimen. Meets criteria for AJCC pathologic T staging.	p
5	Surgical resection performed WITH pre-surgical systemic treatment or radiation, BUT tumor size/extension based on clinical evidence.	c
6	Surgical resection performed WITH pre-surgical systemic treatment or radiation; tumor size and/or extension based on pathologic evidence.	yp
8	Evidence from autopsy only (tumor was unsuspected or undiagnosed prior to autopsy).	a
