Condition
Stage I seminoma testis
Intervention
1. One group receives 30 Gy, given in 15 daily (Monday through Friday) fractions of 2 Gy
2. The other group receives 20 Gy in 10 daily fractions of 2 Gy
Follow-up assessments will take place every three months in year one, every four months in year two, every six months in year three, and annually until year ten. Clinical examination and serum tumors markers will be required at each visit; chest x-rays are required at the six, 12-, 20-, 30-, and 36-month visits; and Computed Tomography (CT) scans of chest, abdomen, and pelvis are required at the 12-, 24-, and 36-month visits.

Secondary outcome measures
Impact of dose on acute morbidity and quality of life.

Eligibility
Participant inclusion criteria
1. Histologically confirmed seminomatous germ cell tumour of the testis that is categorised as either 'Classical' or 'Anaplastic'
2. Stage I disease, based on clinical and radiologic examination, and normal postorchidectomy Alpha-FetoProtein (AFP) and Human Chorionic Gonadotropin (HCG)
3. All 'T' categories of primary tumour are eligible except those with involvement of the cut end of the spermatic cord
4. Patients with previous inguino-pelvic or scrotal surgery, have to be treated with 'dog-leg' fields
5. The interval between orchidectomy and randomisation should not exceed eight weeks. Treatment should start within two weeks thereafter
6. Consent to be randomised into the proposed study
