To analyze the distribution features of Gleason score and evaluate the relationship between Gleason score and clinical stages in patients with prostate cancer.Surveys were made of the inpatients with prostate cancer diagnosed by pathology from January 1992 to June 2005 in our hospital. Gleason score and clinical stages were determined on the basis of pathological examination and clinical data of the prostate cancer patients. The patients were divided into three groups (1992-1999, 2000-2002 and 2003-2005). The Chi-square test was used to evaluate the distribution and differences of Gleason score among the three groups. Spearman rank correlation was applied to the evaluation of the relationship between Gleason score and clinical stages.We found a statistically significant shift in the distribution of Gleason score (chi2 = 17.703, P0.01), and a slight increase in the mean Gleason score. The proportion of moderately differentiated tumor increased (chi2 = 10.736, P0.01). There was little change in the proportion of Gleason score 7, 8, 9 and 10 (chi2 = 4.038, P0.05). Gleason score had a significant positive correlation with clinical stages in the 346 cases of prostate cancer (r = 0.452, P0.01). Significant difference was observed between Gleason score 2-6 and 7 or 8-10 (chi2 = 8.786, P0.01, chi2 = 22.956, P0.01), but not between the latter 2 groups (chi2 = 0.787, P0.05) in prediction of organ-confined disease.Gleason score 7 shows the similar value to Gleason score 8-10 in predicting the progression of the disease. Gleason score was significantly correlated with clinical stages, which suggests that Gleason score is also an important indicator for the prognosis of prostate cancer. |
