title: [Large sections in routine breast pathology. A technique adapted to conservative surgery].
abstract: Large block macrosectioning of segmental excision specimens for breast cancer, and especially ductal carcinoma in situ, provides detailed information regarding size of the lesions, extent of spread and margin status which are essential for local recurrence risk assessment. However, the expansion of this technique has been curbed due to its reputation of being technically difficult, time-consuming, costly and providing slides of poor quality. We assessed the feasibility of the large section technique and adapted it to the everyday practice of a routine pathology laboratory. The time spent cutting a large block on a motorized microtome is half the time spent cutting the great number of conventional blocks needed to assess the same amount of tissue. Finally, 4 mm-thick stained large preparations of high quality are produced within 3 days after receiving the specimen. Analysis and report are both more precise and easier since the pathologist is saved the trouble of having to mentally re-assemble a great quantity of numbered small blocks. 805 primary monobloc segmental excision specimens have been examined in this way over the last 50 months period and we advocate its use as a standard procedure for breast-conserving surgery specimen management.
