Abstract
In the last 20–30 years the availability of effective chemotherapy and more accurate clinical staging has greatly improved the prognosis for patients with testicular germ cell tumours. Initially, such treatment appeared to diminish the role of histopathology to the distinction between seminoma and nonseminomatous germ cell tumour (NSGCT) in the primary specimen. However, histopathology has evolved as a prognostic tool indicating the risk of relapse in various defined clinical contexts thereby facilitating therapeutic decisions. The clinical emphasis has been on quality of life and reduction of therapy both in terms of the number of patients treated and the number of chemotherapy courses given to each patient. The treatment of adult testicular germ cell tumours may differ between countries but protocols are established. Therefore it is appropriate to discuss the role of histopathology during this era of relative therapeutic stability.
