[Correlation between computed axial tomography and ileum obturating lymphadenectomy in localized adenocarcinoma of the prostate].
OBJECTIVE
To correlate the findings of CT and ileoobturator lymphadenectomy in patients with localized adenocarcinoma of the prostate.


METHODS
94 patients with adenocarcinoma of the prostate were evaluated. Ileoobturator lymphadenectomy and brachytherapy were performed in 61.1%, radical prostatectomy in 22.5% and lymphadenectomy with prostatic labeling for subsequent external radiation therapy in 5%. Lymph node CT and pathology findings were correlated.


RESULTS
Of 92 patients with a normal CT scan, 18 had positive nodes and 19.1% were understaged. Two patients with a CT scan suggestive of metastatic adenopathy had negative pathology findings. Seventy-two of the 92 patients with normal CT scans had negative nodes, accounting for a specificity of 76.6%.


CONCLUSIONS
Pelvic lymph node involvement changes the prognosis of prostate cancer. However, the ability of CT to detect lymph node metastasis is limited. It is therefore not a reliable method and raises the costs of staging unnecessarily.
