Prognostic markers in clinical stage I seminoma and nonseminomatous germ cell tumours

Purpose of review Testicular germ cell tumour (TGCT) is a common malignancy among young men. There is controversy regarding the best approach for patients with clinical stage I disease due to rates of relapse with active surveillance in contrast to overtreatment with adjuvant therapy. The aim of this review is to describe the role of prognostic factors in this setting. Recent findings Molecular prognostic factors have been described as a possible future aid to clinical and histologic features in the approach of patients with clinical stage I germ cell tumours. Summary Prognostic factors currently available are not accurate enough and may lead to overtreatment. However, though active surveillance has shown long-term survival near to 100% in the management of clinical stage I germ cell tumours, there is a significant percentage of patients with occult metastatic disease, who benefit from adjuvant therapy. In light of these data, future research is needed to better define high-risk patients for relapse, taking into account molecular markers recently reported.
