Surgical upstaging rates in patients meeting the eligibility for active surveillance trials

ConclusionsThe upstaging rate in patients eligible for the clinical active surveillance trials was 12 –25%. Although the rate of upstaging to pT1b or higher was low, further studies are required to determine the rates of upstaging to invasive cancer and the risk factors among patients with low-risk ductal carcinomain situ.
