• We present a new prognostic classification designated the Van Nuys classification for ductal carcinoma-in-situ (DCIS). The classification combines high nuclear grade and comedo-type necrosis to predict cinical recurrence. Three groups of DCIS patients were defined by the presence or absence of high nuclear grade and comedo-type necrosis: 1—non-high-grade DCIS without comedo type necrosis, 2—non-high-grade DCIS with comedo-type necrosis, 3—high-grade DCIS with or without comedo-type necrosis. There were 31 local recurrences in 238 patients after breast-conservation surgery 3·8% (3/80) in group 1, 11·1% (10/90) in group 2, and 26·5% (18/68) in group 3. The 8-year actuarial disease-free survivals were 93%, 84%, and 61%, respectively (all p0·05). The Van Nuys classification defines three distinct and easily recognisable groups, each of which has a different likelihood of local recurrence if treated with breast conservation.
