Grading of biopsies of laryngeal carcinomas by multiple criteria

The system of tumor grading of Jakobsson et al was applied in a study of the malignancy grade of biopsy tissue compared with the grade of the corresponding tissue obtained at definitive surgery. The results suggest that at biopsy tumors are rated lower grade than they exhibit in the final tumor tissue. Some observations are made on the application of this system of point rating multiple features to determine histologic grade.
