Abstract

OBJECTIVES: To analyse the influence of the main grade of Gleason score 7 of the operative specimen correlated with the blood PSA level on the laboratory progression-free survival of patients treated by radical prostatectomy. MATERIALS AND METHODS: 331 patients consecutively treated by radical prostatectomy and presenting a Gleason score 7 were analysed. Exclusion criteria were the use of radiotherapy and/or preoperative and/or postoperative endocrine therapy. The main grade (3 or 4), histological stage, and blood PSA level were analysed for their predictive value of laboratory progression-free survival. The mean follow-up was 3.5 years (range: 13.6 to 72.8 months). Laboratory recurrence was defined by a PSA > 0.4 ng/ml. RESULTS: The main grade of Gleason score 7 was 3 in 199 (60%) patients and 4 in 132 (40%) patients with a mean follow-up of 3.6 years. Laboratory progression-free survival rates were 89% and 72% for main grades 3 and 4, respectively (p = 0.03). When the cancer was confined to the prostate, the progression-free survival rates were 96% and 88% for main grades 3 and 4, respectively (p = 0.01). For a PSA <10 ng/ml, main grade 3 was associated with a better laboratory progression-free survival rate than main grade 4 (p = 0.0007). No difference in terms of laboratory progression was observed in the presence of extraprostatic extension or PSA > 10 ng/ml. CONCLUSION: A high correlation was observed between the main grade of Gleason score 7 and laboratory progression-free survival. Main grade 3 constituted a factor of better prognosis than main grade 4.
