Stage II testicular seminoma: patterns of recurrence and outcome of treatment

Eur Urol. 2004 Jun;45(6):754-59; discussion 759-60. doi: 10.1016/j.eururo.2004.01.020.


Objectives: To review treatment outcome and patterns of failure for patients with stage II testicular seminoma and to identify prognostic factors for relapse.

Methods: From 1981 to 1999, 126 men with stage II seminoma were treated at Princess Margaret Hospital. Of these, 95 were treated with radiotherapy (RT) and 31 with chemotherapy (ChT). Patient and tumour characteristics were analyzed for prognostic significance for subsequent relapse.

Results: At median follow-up of 8.5 years, the 5- and 10-year overall survival were both 93%, the 5- and 10-year cause-specific survival were both 94% and the 5- and 10-year relapse-free rates were both 85%. Patients with stage IIA and IIB disease treated with RT and stage IIB treated with chemotherapy had 5-year relapse-free rates of 91.7%, 89.7% and 83.3%, respectively. Seventeen percent of patients treated with radiotherapy and 6% of those treated with chemotherapy have relapsed. Of the RT patients the commonest sites of relapse were left supraclavicular fossa, lung/mediastinum, bone, para-aortics and liver; nine patients had a solitary site of relapse. Two patients treated with chemotherapy had recurrence in the para-aortic and iliac nodes. For RT patients, larger primary tumour size was associated with a reduction in relapse rate. Age, rete testis invasion and lymphovascular invasion were found not to be of prognostic significance.

Conclusions: In stage IIA/B seminoma, radiotherapy continues to provide excellent results, as the majority of patients will be cured with this treatment alone. Chemotherapy is the treatment of choice for stage IIC seminoma.
