Purpose:
We report on the morbidity of dynamic sentinel lymph node biopsy (DSNB) in penile squamous cell carcinoma (SCC).
Materials And Methods:
Between 1994 and 2003 DSNB was performed in 129 patients with T2 or T3 penile SCC who had 243 clinically node negative groins. Patients with groins with a tumor positive sentinel node underwent additional standard inguinal lymphadenectomy.
Results:
A total of 285 sentinel nodes were harvested in 223 explored groins. The sentinel nodes were tumor-free in 189 groins. A total of 34 standard inguinal lymphadenectomies were performed because of a tumor positive sentinel node. There were 6 regional relapses during a median followup of 50 months (range 5 to 124) resulting in a false-negative rate of 15% (6 of 40 groins). This rate was 17% when calculated per patient (6 of 35 patients). Early and/or late complications following DSNB only occurred in 7% (14 of 189) of the groins. After DSNB followed by a standard inguinal lymphadenectomy, the rate was 68% (23 of 34). All complications of DSNB were minor and easily managed.
Conclusions:
Morbidity of DSNB in penile SCC is low. However, an in field recurrence after a negative DSNB is perhaps the greatest complication of the procedure.
