Purpose:
Traditional treatment for advanced penile verrucous carcinoma is penectomy. This mostly leads to remarkable psychosexual problems and greatly affects quality of life, especially in young patients. To preserve the penis we used intra-aortic infusion chemotherapy for advanced verrucous carcinoma.
Materials And Methods:
From 1991 to 2009 we treated 6 men with penile verrucous carcinoma with continuous intra-aortic infusion of 50 mg methotrexate every 24 hours (average 550 mg, range 400 to 800). Citrovorum factor (6 mg) was given intramuscularly every 6 hours during methotrexate infusion. After continuous methotrexate infusion no further anticancer drug was given to complete responders. Partial responders subsequently received long-term, intermittent, intra-aortic infusion of 50 mg methotrexate or 2 mg mitomycin C plus 250 mg 5-fluorouracil every 1 to 2 weeks until tumors disappeared and all wounds healed.
Results:
After treatment 4 patients achieved a complete response and were disease-free 3 years 9 months to 17 years 10 months (median 11 years 3 months) after therapy. Two patients had a partial response. The patient with a shaft tumor subsequently underwent total penectomy due to unbearable penile pain 4 years after infusion with various drugs without an appreciable response. He has survived 12 years 5 months after initial treatment. The other patient with glans and prepuce tumors had progression with bilateral inguinal metastases despite 1 1/2 years of infusion therapy. Total penectomy was done. Histological examination of the glans mass revealed moderately differentiated squamous cell carcinoma. Patient condition progressed rapidly and he died 11 months after penectomy.
Conclusions:
Intra-aortic infusion chemotherapy is a simple, effective method to treat penile verrucous carcinoma with the uniqueness of preserving the anatomical structure and sexual function in complete responders. For penile verrucous carcinoma, especially in younger patients, intra-aortic infusion chemotherapy may be considered organ sparing treatment before penectomy.
