Surveillance is every three months for two years, every 6 months for the next three years, and then yearly.
Depending upon the country and the person's resources, surveillance might be as follows:

In the US, the protocol is usually:  Spiral CT scan of Chest, Abdomen, Pelvis with contrast, plus usual interim history, physical exam, urine and blood tests.  

Other countries might favor the 'economy' route:  substitution of ultrasound of abdomen and pelvis for routine abdominopelvic CT, and substituting Chest X-rays for the routine chest CT, with a CT chest six monthly, plus usual interim history, physical exam, urine and blood tests.
