ROLE OF SENTINAL LYMPH NODES BIOPSY USING TECHNETIUM-99M NANOCOLLOID IN PENILE CANCER
Main Article Content
Abstract
Objective: To evaluate the accuracy of sentinel lymph node biopsy by comparating SLN and regional lymph node metastasis in high risk penile cancer patients. Patients and methods: We described a series of 50 cases of cN0 T2-4 or Grad 3 penile cancer patients who underwent SLNB with Tc-99m. Results: The success rate of mapping was 94% by nodal region and 100% by patient. The sensitivity, specificity, accuracy, and false negative rate of Tc-99m SLNB were 85.7%, 100%, 98.9%, and 14.3%, respectively. Conclusion: Tc-99m guided SLNB may accurately predict the regional lymph node metastasis in penile cancer patients.
