1981) did not describe Hopkins grading system but Jewett et al. had defined it in 1968. Gleason (1977) has compared his system with other grading systems. His 2-4 are grade I, his 5-7 are grade II, and his 8-10 are grade III. 3% of his grades II and III, respectively-indicative of lack of discrimination between his grades II and III. Pistenma et al. (1979) and Bagshaw (1984) have claimed that when Gleason patterns were less than 5, no positive lymph nodes were present. On the other hand, Olsson (1985) reported nodal involvement in 20% or more of patients with Gleason 2-4 primary lesions.

Grade II: The proportion of differentiated and undifferentiated components is about equal. Grade III: Three-fourths of the tumor is undifferentiated, one-fourth of the tumor is differentiated. Grade IV: The tumor shows no tendency to cell differentiation. In subsequent years the reproducibility and the reliability of grading tumors have been controversial. Indeed, even today, grading on the same slides may vary from grade 1 to grade 3 or even 4. This is attributable to the fact that differentiation has not been clearly defined-histology vs cytology-so that some have graded the tumor on structural differentiation, others on cellular differentiation, and still others on cellular anaplasia.

1970) reported local spread in 25% of Gleason grade 1 and 28% of Gleason grade 2 tumors (the authors state that they used Gleason's system and it is probably the predominant pattern that they used rather than the sum). 8% of patients with Gleason grade 5 had stage C and D tumors, respectively, on admission. On the other hand, Kramer et al. (1980) claimed that 100% of patients with stage A, B and C disease with Gleason grades 9 and 10 tumors and 90% of Gleason grade 8 tumors had positive lymph nodes.
