Summary
Squamous cell penile cancer (pT1 G2) has a higher metastatic potential than previously thought. Early inguinal lymph node dissection (ILND) is recommended due to decreased morbidity and improved outcomes compared to delayed ILND.
Area of Science:
- Oncology
- Urology
Background:
- Squamous cell penile cancer (pT1 G2) management remains controversial due to low incidence and limited studies.
- Therapeutic strategies for pT1 G2 penile carcinoma lack definitive evidence.
Purpose of the Study:
- To evaluate the metastatic potential of pT1 G2 squamous cell penile carcinoma.
- To compare outcomes of surveillance versus inguinal lymph node dissection (ILND) for pT1 G2 penile cancer.
Main Methods:
- Retrospective analysis of 16 patients with T1 squamous penile cancer treated between 1992 and 2003.
- Treatment modalities included surveillance or inguinal lymph node dissection (ILND).
Main Results:
- Four of 8 pT1 G2 squamous penile tumors developed inguinal metastatic disease.
- Early ILND demonstrated reduced morbidity and superior outcomes compared to delayed ILND.
Conclusions:
- The metastatic potential of pT1 G2 penile carcinoma is underestimated.
- Early modified inguinal lymph node dissection (ILND) is advocated for pT1 G2 penile cancer.
- Further validation of prognostic factors for inguinal lymph node positivity is needed.
