Purpose
To evaluate the oncological and functional outcomes of patients diagnosed with penile cancer undergoing conservative treatment through thulium–yttrium–aluminium–garnet (Tm:YAG) laser ablation.
Methods
Twenty-six patients with a penile lesion underwent ablation with a RevoLix 200 W continuous-wave laser. The procedure was carried out with a pen-like laser hand piece, using a 360 μm laser fiber and 15–20 W of power. Median (IQR) follow-up time was 24 (15–30) months. Recurrence rate and post-operative sexual function were assessed.
Results
Median age at surgery was 61 years. Median (inter quartile range) size of the lesions was 15 [10–20] mm. Overall, 11 (47.8%) and 12 (52.2%) at the final pathology presented in situ and invasive squamous cell carcinoma (SCC), respectively. The final pathological stage was pTis, pT1a, pT2, and pT3 in 11 (47.8%), 7 (30.4%), 3 (13.0%), and 2 (8.7%) patients, respectively. Moreover, four (17.4%) patients had a recurrence of which three (13.0%) and one (4.3%) patients developed an invasive or in situ recurrence, respectively. After treatment 6 (26.1%) patients reported a conserved penile sensitivity, while 13 (56.5%) and 4 (17.4%) patients experienced a better or worse sensitivity after ablation, respectively. Post-treatment sexual activity was achieved within the first month after laser ablation in 82.6% of the patients.
Conclusion
Early stage penile carcinomas can be effectively treated with an organ preservation strategy. Tm:YAG conservative laser treatment is easy, safe and offers good functional outcome, with a minor impact on patient’s quality of life.
