Abstract:
ObjectiveTo analyze the clinicopathological characteristics and survival time of penile cancer after surgery.MethodsThe clinicopathological data of 93 cases of penile cancers patients treated from January 2002 to December 2010 were collected retrospectively.The Kaplan-Meier method was used to draw the survival function and calculate the survival rate.Log-rank test was further used to compare survival difference.ResultsThe median age of the 93 patients was 51 years ( range,23 to 82).Squamous carcinoma was most common with 87 eases (93.5％) in our group.Sixty-one patients were successfully followed up and the median follow up duration was 28 months(range,2 to 89 months).All 3 cases of verrucous carcinoma had progression free survive after surgery after follow up of 12,19,and 67 months.In the 55 patients with penile invasive squamous carcinoma,11 patients died of metastatic disease with a median survival time of 10 months ( range,2 to 24 months).Two years cumulative survival rate was 75.7％ (95％ CI 63.0％ to 88.4％ ).Six cases of 12 patients with lymph node metastasis died of penile cancer while only 5 cases of 43 patients without lymphnode metastasis died.The survival difference was significant (log rank,P =0.000).ConclusionsSquamous carcinoma is the most common type,and patients with lymphnode metastasis have poor prognosis.Verrucous carcinoma has good prognosis.
