Abstract
												A higher CTR and an increase in CTR during follow-up were associated with invasive cancer. A follow-up period of 3 years is considered to be adequate for judging tumor growth in patients with a CTR > 0, whereas a longer follow-up period might be needed for patients with a CTR of 0.
