van Maaren MC, et al. - In ductal carcinoma in situ (DCIS) patients following surgical treatment in the Netherlands, authors ascertained the breast cancer-specific survival (BCSS) and overall survival (OS) according to grade. They selected all DCIS patients diagnosed between 1999 and 2012 from the Netherlands Cancer Registry. In DCIS patients, they noted excellent BCSS and OS. As experts observed superior rates for low-grade DCIS, investigating whether active surveillance may be a balanced alternative for conventional surgical treatment was justified.
