[Clinical study of penile cancer].

Recent progress in molecular biology suggests a certain relationship between penile cancer and human papilloma virus infection. However, the treatment for penile cancer has not been established since each institute has experienced only a small number of patients. We analyzed the result of our treatment for 14 penile cancer patients during past twenty years. Ten of the 14 patients were initially treated for the primary lesion with a combination of peplomycin (PEP) or bleomycin (BLM) and radiation therapy. Of these, 9 were found not to have residual viable cancer cells in their primary lesions. No local recurrence was found in all 7 patients in whom the penis was preserved. This result suggests that combination of PEP (BLM) and radiation preserves the penis without increasing the risk of local recurrence. Penile cancer-related death did not occur in patients without lymph node metastasis. However, this cancer death did occur in 4 out of 7 patients with lymph node metastasis, suggesting that metastasis is one of the important prognostic factors. PEP (BLM) and radiation therapy with or without regional lymph node dissection did not improve the prognosis of patients with advanced penile carcinoma, such as with pN2, pN3 or distant metastasis. More effective management may be necessary for these patients.
