作者研究66例膀胱前列腺全切的前列腺标本。所有病人术前均无前列腺癌的病史及临床表现。其中64例为膀胱肿瘤;1例为直肠癌侵及膀胱后壁;1例间质性膀胱炎。平均年龄64岁(31—83岁)。 66例病人中,25个前列腺标本中发现38处前列腺癌灶,发生率为38％。 25例阳性病人中,10例(40％)前列腺标本上为多发癌肿(7例2处,3例3处)。38个癌灶的平均体积为0.1CC(0.01CC—1.1CC)。其中5个癌灶超过0.1CC(0.27,0.42,0.60,0.96,1.1CC)33个癌灶小于0.1CC(87％),19个癌灶小于0.01CC(50％)。所有癌灶均无全层前列腺包膜侵润。也无精囊
The authors studied 66 cases of prostate specimens that had undergone full-thickness prostate prostatectomy. All patients had no history or clinical manifestations of prostate cancer before surgery. Of these, 64 were bladder tumors; 1 was rectal cancer invading the posterior bladder wall; 1 was interstitial cystitis. The average age is 64 years (31-83 years old). Of the 66 patients, 38 prostate cancer lesions were found in 25 prostate specimens, with an incidence of 38%. Among the 25 positive patients, 10 (40%) prostate cancers had multiple cancers (2 in 7 and 3 in 3). The average volume of 38 foci was 0.1CC (0.01CC-1.1CC). Among them, 33 lesions of more than 0.1CC (0.27, 0.42, 0.60, 0.96, 1.1CC) were less than 0.1CC (87%), and 19 lesions were less than 0.01CC (50%). All the foci had no full-thickness prostate capsule invasion. There is no seminal vesicle
