前列腺腺癌根治术切除标本


根治性前列腺切除术所得的前列腺标本,展现的是后部的(上图可见)不规则黄*色小结节。证实为前列腺腺癌。含有腺癌的前列腺体不一定增大。另外,腺癌可与增生共存。不过,前列腺增生不是癌前病变。前列腺腺癌的分级是根据肿瘤的浸润程度而定的。
These sections through a prostate removed via radical prostatectomy reveal irregular yellowish nodules, mostly in the posterior portion (seen here superiorly). This proved to be prostatic adenocarcinoma. Prostate glands containing adenocarcinoma are not necessarily enlarged. Adenocarcinoma may also coexist with hyperplasia. However, prostatic hyperplasia is not a premalignant lesion. Staging of prostatic adenocarcinoma is based upon how extensive the tumor is.
