Participants in the 1992 College of American Pathologists'Q-Probes Study of bladder carcinoma surgical report adequacy evaluated 7234 bladder biopsies and curettings from 268 institutions.
In over 98% of the cases evaluated, the histologic type was stated.
In over 95%, the histologic grade was stated where appropriate.
Of the 7234 cases studied, 2149 (29.7%) were invasive, 4498 (62.2%) were noninvasive, and invasiveness (presence or absence of invasion) was not stated for 587 (8.1%). For invasive carcinomas, there was definitive assessment for the presence or absence of muscularis propria in 1145 (53.3%) of 2149 cases, and in 67 (3.1%) of 2149 cases no muscle or muscularis was present.
For noninvasive carcinomas, there was a definitive evaluation of the muscularis propria (presence or absence) in 1349 (30%) of 4498 cases.
