Fascia lata preservation during inguinal lymphadenectomy for penile cancer: rationale and outcome.

OBJECTIVE

To investigate local groin recurrence and morbidity associated with fascia lata preservation during inguinal lymphadenectomy (LAD) for penile carcinoma.

METHODS

Between January 2002 and December 2011, 201 inguinal dissections with preservation of the fascia lata were performed in 104 patients with clinical disease staged at ≤N2. The dissection boundaries were the same as those for radical inguinal LAD. All superficial inguinal nodes were removed en bloc. The cribriform fascia near the femoral canal was divided, and the deep inguinal lymph nodes were dissected. The fascia lata was completely preserved and sutured to the subcutaneous tissue. Sartorius muscle transposition was eliminated. Survival and morbidity data were retrospectively analyzed, and survival probabilities were calculated.

RESULTS

The median operative time for unilateral inguinal LAD was 45 minutes (range, 40-60 minutes). Median follow-up was 36 months (range, 10-130 months). A mean number of 12.5 nodes were removed per groin. One patient (1%) had a recurrence outside the borders of the fascia lata after 7 months of follow-up. The 3-year disease-free survival rate was 92.1% (100% for pN0, 91.3% for pN1, 80% for pN2, and 33.3% for pN3 disease). A total of 59 complications (29.3%) occurred, including wound infection (2.5%), skin necrosis (5.5%), lymphedema (11.8%), seroma formation (1.5%), lymphocele (5%), paresthesia (3.5%), and deep venous thrombosis (0.5%).

CONCLUSION

Inguinal dissections with preservation of the fascia lata for penile carcinoma patients without extranodal extension is as effective as the classic dissection technique but decreases complications related to groin dissection.
