Objectives:
Although in many cases of penile carcinoma, laser therapy has become the standard treatment, opinion still differs regarding the risks related to the relatively high rate of recurrence that accompanies this form of treatment. In this study, we reviewed the results of neodymium:yttrium-aluminum-garnet laser treatment of 44 consecutive patients with penile carcinoma in our institution from 1986 to 2003.
Methods:
We created five groups, on the basis of the T stage and grade of the tumor. Of the 44 patients, 21 had Stage T1, 17 had Stage T2, and 6 had carcinoma in situ.
Results:
Local disease recurrence (in the treated area) occurred in 48% of the treated patients, and in 20% of the patients, the first recurrence was elsewhere on the glans penis. These were subsequently treated by laser therapy or partial amputation. In 10 cases, nodal metastases were found. Eight of these cases were Stage T2. Our results suggest a stronger prognostic role for the primary T stage of the tumor than for the tumor grade, with respect to the risk of nodal metastasis.
Conclusions:
From the high recurrence rate in our series, we decided to perform a wider initial laser excision and to diminish the number of retreatments to less than three. We also now believe that laser therapy is best for Stage Tis and T1 tumors exclusively. Only selected patients with T2 tumors should be treated in combination with early lymph node resection.
