ABSTRACT

Objective To improve the diagnostic level of on pelvic nodal metastases of prostate cancer. Methods Thirty-three cases of prostate cancer underwent instep lymphangiography to find out if there were pelvic nodal metastases.The results of lymphangiography were compared with the pathologic results of fine needle aspiration biopsy of lymph nodes. Results In the 9 cases testing positive for nodal metastases 7 were identified by cytology of fine needle aspiration biopsy and 6 were confirmed by pathology;while in the 24 cases with negative results,4 were false negative(17%). Conclusions The lymphangiography plays an important role in diagnosis of nodal metastases of prostate cancer.Fine needle aspiration for suspected lymph nodes can minimize false positive result,nevertheless there is still false negative result in lymphangiography.
