Although in our series there is not a significant difference in LR rates by the parameter of age, the new USC/VNPI is still a simple and reliable scoring system for therapeutic management of DCIS. We did not find any statistically significant advantage in groups treated with the addition of RT. Obtaining wide surgical margins appears to be the strongest prognostic factor for local recurrence, regardless of other pathological factors or the addition of adjuvant radiation therapy. However, only prospective randomized studies can precisely predict the risk of LR of conservatively treated DCIS. The clinical significance of Sentinel Lymph Nodes micrometastases Immuno-Histo-Chemistry-detected found in DCIS patients remains uncertain. However, we hypothesize that the anatomical disruption after preoperative biopsy procedures increases the likelihood of epithelial cell displacement and the frequency of IHC-positive Sentinel Lymph Nodes, both of which are directly proportional to the degree of manipulation.

The treatment for breast cancer is sometimes long and requires a multidisciplinary approach. In 2010, in our centre, we began to perform fat grafting for breast reconstruction using the so-called 'reverse expansion' technique. This consists of the insertion of a skin expander during mastectomy, in its expansion and then in its gradual deflation in the surgical theatre during fat grafting. We performed a complete breast reconstruction in 57 patients by reverse expansion. We harvested fat from the fat excess areas using a normal liposuction cannula. From each patient, an average of 640 ccs of was collected and then centrifuged in a 4000-rpm centrifuge for 3 min. The obtained adipocytes were then injected in the operated breast using a normal lipofilling cannula. We injected an average of 318.05 ccs of adipocytes for each patient each time. The average number of sessions per patient was 3.6. Reverse expansion can be a safe and effective technique for breast reconstruction in all the breast cancer patients.
