偶发前列腺癌的临床和病理特征分析

Clinical and pathological analysis of incidental prostatic carcinoma.

目的探讨偶发前列腺癌的临床和病理组织学特征。方法回顾性分析2000年1月至2013年3月我院107例前列腺癌患者的临床和病理组织学资料,分为偶发前列腺癌组23例和非偶发前列腺癌组84例,并将两组进行对比。结果偶发前列腺癌组与非偶发前列腺癌组相比较,患者年龄、病理组织类型差异无统计学意义(P>0.05);直肠指诊前列腺大小差异有统计学意义(P<0.05);偶发前列腺癌组血清前列腺特异性抗原水平、病理分级、病理分期较低,差异有统计学意义(P<0.05)。结论临床上偶发前列腺癌患者血清前列腺特异性抗原水平低,具有病理分级及分期低的特点,充分取材及有效病理检查有助于偶发前列腺癌的检出。

Objective To study the clinical and pathological features of incidental prostatic carcinoma. Methods The clinical data of 107 eases with prostatic carcinoma were analyzed retrospectively from January 2000 to March 2013. Patients were divided into two groups： incidental prostatic carcinoma group （n=23） and non-incidental prostatic carcinoma （n=84）. Results There were no differences between the two groups in age and pathological tis- sue types （P〉0.05）. However, incidental prostatic carcinoma might be of smaller size, lower prostate-specific antigen （PSA）, stage and grade than non-incidental prostatic carcinoma （P〈0.05）. Conclusion Incidental prostatic carcinoma has low PSA, stage and grade. Pathological examination could contribute to the detection of prostatic carcinoma.
