[Glans-preserving surgery for superficial penile squamous cell carcinoma ≥2 cm in diameter].

OBJECTIVE

To explore the feasibility of glans-preserving surgery (GPS) in the treatment of superficial penile squamous cell carcinoma (PSCC) with the lesion diameter of ≥2 cm.

METHODS

We retrospectively analyzed the clinical data on 69 cases of superficial PSCC (≤T1aN0) treated by GPS (n = 36) or radical surgery (total or partial penectomy, n = 33) from July 2007 to July 2017.

RESULTS

The mean tumor diameter and depth of invasion were 3.16 (2.0－6.0) cm and 0.89 (0.5－2.0) cm in the GPS group and 3.56 (2.0－6.0) cm and 1.89 (0.6－4.0) cm respectively in the radical surgery group. The patients were followed up for 10－102 (mean 42) months, during which, 5 patients in the GPS group developed local recurrence at 40 days and 2, 4, 7 and 9 months postoperatively, again underwent gansectomy, partial penectomy or GPS, and experienced no more recurrence during the follow-up of 54, 34, 39, 66 and 70 months. No local recurrence was observed in the radical surgery group, and none of the 69 patients experienced lymph node metastasis or died during the follow-up.

CONCLUSIONS

GPS is safe and efficient for the treatment of superficial PSCC with the lesion diameter of ≥2 cm.
