Incidental adenocarcinoma of the prostate in transuteral resection due to benign causes: Hospital de San José, July 2006 to March 2008

Adenocarcinoma incidental de próstata en resección transuteral por causa benigna: Hospital de San José, julio 2006 a marzo 2008

Transurethral resection of the prostate is a common procedure to treat benign obstructive urinary diseases. ', 2 The material obtained is histologically studied to confirm the benign nature, but in some cases an adenocarcinoma has been found incidentally in early stages. It is not clear how much material should be processed or if the amount of tissue examined increases the chance of finding cancer. The objective of this study is to determine the frequency of incidental adenocarcinoma of the prostate in patients undergoing TURP due to benign causes. It gathers 196 cases of TUR in which all the remaining tissue obtained was processed in a second phase, describing the variables age, weight of the specimen, number of processed slides, PSA levels and diagnostic category, which was classified as negative for maglinidad, High grade PIN and prostate adenocarcinoma Tla and Tlb stages. It was found that the frequency of prostate cancer in patients who underwent TURP due to benign prostatic hyperplasia in the Hospital of San José was very low, two patients of 71 and 80 years, in addition to another that corresponds to a high grade intraepithelial neoplasia. (AG PIN) with normal PSA levels, which shows that the frequency is lower than that reported in the international literature. 3 '4 Abbreviations: CIP, incidental carcinoma of the prostate; RTU, transurethral resection of prostate; PIN AG high grade prostatic intraepithelial neoplasia; PSA, specific prostatic antigen; TNM, classification system of tumor stage (T: tumor, N: lymph nodes, M: metastasis).
