Abstract：Objective:To evaluate the mitochondrial function score in combination with Gleason score in predicting the progression of prostate cancer. Methods:This study included twenty 58 -79 (70.1 ± 1.2) years old patients with prostate cancer treated by radical prostatectomy. The epithelioglandular mitochondrial function scores of the patients were obtained under the transmission electron microscope and assessed according to Flameng grading. Meanwhile,their Cleason scores were analyzed and,based on the scores,the patients were divided into Groups Ⅰ (Gleason score:2-4) and Ⅱ (Gleason score; 5-7). Results:The mitochondrial function score of Group I was significantly different from that of Group Ⅱ(4.0 ± 0.8 versus 2.3 ± 0.6,P < 0.05),with a negative correlation with the Gleason score (r = - 0.793,P < 0.05 ). One year follow-up showed a significantly lower mortality in Group Ⅰ (0/8) than in Group Ⅱ (6/12) (P < 0.05). Conclusion:Mitochondrial dysfunction exists in prostate cancer patients,particularly in those with higher malignancy. The mitochondrial function score combined with Gleason score plays a valuable role in predicting the progression of prostate cancer.
