1980～1985年行TURP治疗前列腺增生症434例,术后病理诊断为前列腺偶发癌28例(6.5%),年龄54～87岁,平均68.5岁,70岁以上偶发癌发病率有增高倾向。28例均为腺癌,其中高分化癌19例(68%),其腺管腔内类晶体(Crystalloid)阳性者10例(53%);中分化和低分化腺癌共9例(42%)。分为三组,对预后进行了观察比较。结果高分化癌伴类晶体阳性组均获长期生存,高分化癌类晶体阴性组生存期低于前者,虽比中分化及低分化组有延长倾向,但无显著性差异(P>0.05)。28例5年后总复发率为28.5%,高分化癌类晶体阳性组复发率为33%,中分化及低分化癌组为55%,而高分化癌类晶体阳性组无
1980-1985 TURP treatment of 434 cases of benign prostatic hyperplasia, postoperative pathological diagnosis of prostate accidental cancer in 28 cases (6.5%), aged 54 to 87 years, an average of 68.5 years old, occasional cancer incidence rate of 70 years or older tends to increase. All 28 cases were adenocarcinomas, of which 19 cases (68%) were well-differentiated carcinomas, 10 cases (53%) were positive for crystalloid-type crystalloids, and 9 cases were moderate-differentiated and poorly differentiated adenocarcinomas (42%). ). Divided into three groups, the prognosis was observed and compared. RESULTS: The well-differentiated cancer-associated crystal positive group had long-term survival, and the survival time of the well-differentiated cancer-like crystal negative group was lower than the former, although there was a prolonged tendency compared with the moderately differentiated and poorly differentiated groups, but there was no significant difference (P>0.05). 28 cases had a total recurrence rate of 28.5% after 5 years. The recurrence rate of well-differentiated cancer-type crystal positive group was 33%, while that of moderately-differentiated and poorly differentiated cancer group was 55%, while the well-differentiated cancer-type crystal positive group had no
