Abstract #1066
Introduction and Aims: The achievement of a pathologic complete response (pCR) after preoperative chemotherapy (PCT) is a validated surrogate end point for long term outcome. On the other side, patients with residual disease in the breast and/or axilla are an heterogeneous group with very different prognosis, including both patients with truly chemo-resistant disease as well as patients with an important tumor downstaging even if not in pCR. Aim of this analysis is to identify, in patients with residual disease, potential markers able to discriminate patients at higher risk of relapse.
 Patients and Methods:. The following parameters were evaluated on the surgical specimen in patients with less than pCR following PCT: residual breast disease, number of involved nodes, proliferation (Ki 67), hormone receptor, HER2, p53, EGFR, VEGFR2. Survival curves were estimated with the Kaplan-Meier method and the log rank test was used to test for differences between groups. Hazard Ratios and their confidence intervals were estimated by using Cox model.
 Results: 195 breast cancer patients were included. Median age 51 yrs (range: 27-73); 71% of the patients had ER+ tumors at diagnosis, 20% were HER2+. After PCT, 55% of the patients received mastectomy, 45% underwent conservative surgery. 57% of the patients had residual breast disease < 2 cm; 38% between 2-5 cm; 35% had no involved nodes, 30% 1-3 nodes, 19% 4-9 nodes, and 16% > 10 nodes; 50% of the patients had Ki 67 >/= 15%. Among the examined parameters, nodal positivity and Ki 67>/=15% were significantly related with a higher risk of relapse (HR 2.5 , p=0.014 and HR 3.4, p <0.0001 respectively). Ki 67 >/=15% was also predictive of a higher risk of death (HR 4.1, p=0.007). On the basis of these two parameters, patients were classified in three groups: 1) low risk (negative nodes and Ki 67<15%): 14.4% of the patients ; 2) intermediate risk (nodal positivity or Ki67 >/= 15%): 54.4% of the patients; 3) high risk (nodal positivity and Ki 67>/= 15%): 31.2% of the patients. Five-year DFS rates were 90%, 72%, and 43% respectively (log rank test p<0.0001); as compared with the low risk group, the HRs for recurrence were 3.1 and 9.3 for the intermediate and high risk group respectively (p=0.0001). Five-year OS rates were 86%, 88%, and 64% respectively (log rank test p=0.035); as compared with the low risk group, the HRs for death were 2.4 and 6.5 for the intermediate and high risk group respectively (p=0.042).
 Conclusions: In this series of patients, Ki 67 and nodal status have been used to generate a simple and easily reproducible prognostic model, able to discriminate patients with worse prognosis among the heterogeneous group of women with residual disease after PCT. In the era of customized treatment strategies, patients at higher risk are the optimal candidates to study the efficacy of additional postoperative treatments.

Abstract
Zn2+ appears to stabilize the myelin sheath but the mechanism of this effect is unknown. In a previous report we have shown that zinc binds to CNS myelin basic protein (MBP) in the presence of phosphate and this results in MBP aggregation. For this paper we used a solid phase zinc blotting assay to identify which myelin proteins bind zinc. MBP and a 58 kDa band were found to be the major targets of 65Zn binding. Moreover, using fluorescence, light scattering and electron microscopy we investigated the binding of zinc and other cations to purified MBP in solution. Among the cations tested for their ability to interfere with the binding of zinc, the most effective were cadmium, mercury and copper, but only cadmium and mercury increased the scattering intensity, whereas MBP aggregation was not inhibited by copper ions. Thus, the effect of zinc on the formation of MBP clusters seems to be specific.

Abstract
Authors value the resistance given from biological tissues in brachifacial, mormofacial and dolicofacial patients to know current intensity used during orthodontic therapy for bone remodelling. This study shows that a thicker biological structure gives more resistance to the current flow than other tipologies.
