What is the best prognostic marker of CA penis

The prognosis of penile cancer is primarily related to the presence or absence of inguinal node metastasis. Untreated patients with inguinal metastases rarely survive 2 years. Of those with clinically palpable adenopathy and histologically proven metastases, 20-50% are alive at 5 years following inguinal lymphadenectomy.The results are even better when the extent of the nodal involvement is considered. When the nodes are positive, the overall recurrence rate is 80%, and the 5-year survival rate is 10%-15%. Fixed lymph node status indicates the advancement of the disease.
