Lymph Node Aspiration Biopsy and Lymph Node Dissection in Prostatic Cancer
A significant number of patients with localised prostatic cancer have regional lymph node metastases. The incidence of pelvic lymph node involvement is closely related to the stage and grade of the tumour. Donohue et al  have reviewed the recent literature and reported that 23% of patients with stage A2, 18% with stage B1, 35% with stage B2 and 46% with stage C disease have pathologically documented lymph node spread. Correlation of grading and lymph node metastasis was demonstrated by Kramer et al  when Gleason’s grading system was used. No lymph node involvement was found in patients with Gleason’s score 2, 3 or 4 in this study, nor in the study by Paulson et al  with the Urologic Oncology Group. However, the National Prostatic Cancer Project revealed a 30.5% incidence of lymph node invasion in low Gleason’s scores , On the other hand, most reports agree on the high incidence of lymph node metastases in patients with high-grade tumour.
