Prostate glands from 52 patients with clinical stage B carcinoma were examined using two sampling techniques.
After fixation and conization of the apical portions, each gland was serially sectioned with sections mounted whole on oversized glass slides and examined for pathologic features of prognostic importance.
A second examination was subsequently conducted on the same tissue using only alternate sections.
No differences in tumor type, grade, Gleason score, multiplicity, or capsular penetration were detected in 75% of cases.
The discrepancies that did occur were most often minor variations in multiplicity and Gleason score.
Of the 20 glands with capsular penetration observed with the serial sectioning method, 17 (85%) were detected using alternate sectioning.
