Detection of Pelvic Lymph Node Metastases in Patients With Clinically Localized Prostate Cancer: Comparison of [18F]Fluorocholine Positron Emission Tomography-Computerized Tomography and Laparoscopic Radioisotope Guided Sentinel Lymph Node Dissection

Extended pelvic lymph node dissection reveals a higher number of lymph node metastases as described for obturator fossa dissection only. [18F]fluorocholine combined in-line positron emission tomography-computerized tomography is not useful in searching for occult lymph node metastases in clinically localized prostate cancer. Sentinel guided pelvic lymph node dissection allows the detection of even small lymph node metastases. The accuracy of sentinel pelvic lymph node dissection is comparable to that of extended pelvic lymph node dissection when the limitations of the method are taken into consideration.
