摘要
目的:通过将前列腺癌根治术后Gleason评分3+4和4+3患者进行对比,评价不同主要Gleason级别患者的临床特征差异。方法:回顾分析2001~2006年于我院行耻骨后前列腺根治性切除术的前列碌碌癌患者,37例木后病理诊断为Gleason7分,根据主要级别不同分为3+4、4+3两组。定期随访判断患者有无生化复发或远处转移。应用放射免疫法检测血清前列腺特异性抗辱(PSA)浓度,Kaplan—Meier法描述两组患者无进展生存曲线,COX回归模型分析影响疾病进展的独立相关田素。结果:两组患者前列腺包膜外侵犯率无统计学差异(21.1% vs 33.3%,P=0.462);3+4组患者术后无进展生存时间长于4+3组(P=0.030);COX回归模型显示Gleason级别是影响预后的独立相关因素(P=0.033),4+3组有着更高的生化复发风险。结论:不同分级的Gleason7分前列腺癌的生物学行为不尽相同,根治术后3+4分和4+3分患者的预后明显不同,将Gleason7分患者依照主要级别继续分型在临床上具有一定的可行性。
Objective:To compare the clinical characteristics of patients with Gleason score 3+ 4 and Gleason score 4+ 3 after radical prostatectomy for prostate cancer. Methods: The clinical records of patients who underwent radical retropubic prostatectomy in our hospital from 2001 to 2006 were retrospectively analyzed. Thirty-seven patients with a Gleason score of 7 after operation were divided into 2 groups.Gleason score 3+4 group and (;leason score 4+3 group,accordlng to major grading. The patients were followed up for biochemical recurrence and distant metastases. Radioimmunoassay was used to detect the serum prostate-specific antigen (PSA) level. Kaplan-Meier method was used to compare the progression-free survival curves and Cox regression model was used to analyze the independent factors influencing the disease progression. Results: The rates of extraprostatic extension at radical prostatectomy were not significantly different between 3+4 and 4+3 groups (21. 1% vs 33.3%,P=0. 462). The non progression survival time of 3+ 4 group was markedly longer than that of 4+ 3 group (P= 0. 030). Cox regression model showed that Gleason primary grade was an independent factor of prognosis (P= 0. 033). 4+ 3 group had a higher risk for biochemical recurrence. Conclusion: Prostate cancers of Gleason score 7 with different grades have different biologic behaviors. The prognoses of patients in 3+4 group and 4 + 3 group are different after operation. It is quite feasible to further classify the patients with Gleason 7 according to major grades.
