Background and Objective: It remains controversial whether sentinel lymph node biopsy (SLNB) should be performed before or after neoadjuvant therapy (NAT). We aimed to evaluate the feasibility and accuracy of SLNB before NAT at a single institution, and to determine its relation to patient prognosis., Methods: A prospective study of T1c-T2-T3 N0 breast cancer patients, after ultrasound examination, who underwent SLNB prior to NAT. Overall, disease-specific and disease-free survival were calculated by Kaplan-Meier curves., Results: SLNB before NAT was performed in 123 patients from December 2006 to May 2014. The identification rate was 100%. SLNB was positive in 42.3% of cases (27.6% macrometastases). NAT was chemotherapy in 88.6% of cases and endocrine-therapy in 11.4%. Lymphadenectomy was avoided in 72.4% of cases. Median follow-up was 40 months (range 8-100). Overall and disease-free survival was 90.2% and 88.6% respectively.SLN involvement was not related to patient outcome (p 0.72); however there were significant differences in survival according to molecular-like subtypes (p < 0.025) and NAT response (p < 0.0001)., Conclusions: SLNB prior to NAT is an accurate method of axillary staging associated with a high identification rate. It avoided lymphadenectomy in more than 70% of patients. SLN involvement did not worsen the prognosis in our cohort., (Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd.

Background: Evidence indicates that advanced maternal age is associated with adverse obstetric and perinatal outcomes. The purpose of this study was to evaluate pregnancy outcomes in women of advanced maternal age (≥40years)., Methods: Using a prospective study design, data were collected by the Department of Obstetrics at the San Joan de Deu Hospital of Barcelona during the 1 June 2009 to 31 May 2012 period. The results were compared across three maternal age groups (≥40 [n=654], 35-39 [n=2781], and <35 [n=7893] years)., Results: Of the 11328 births recorded during the study period, pregnancy-related complications were more common in women ≥40years of age. The most common disorder was diabetes (8.5% in the ≥40, 5.3% in the 35-39, and 3.0% in the <35years age groups). The women ≥40years of age also had significantly more premature births (p=0.001) and cesarean sections (17% in the ≥40, 12.5% in the 35-39, and 7.9% in the <35-year age groups; p=0.001). Intrauterine growth retardation was significantly more frequent in women aged ≥40years (17.4% in the ≥40, 15% in the 35-39, and 14.0% in the <35-year age groups; p=0.03). Fetal macrosomia was significantly more common in women ≥40years (15.4% in the ≥40, 12.6% in the 35-39, and 12% in the <35-year age groups; p=0.03)., Conclusion: Maternal age ≥40years was associated with poorer obstetric and perinatal outcomes and increased the risks of cesarean section, intrauterine growth retardation, and fetal macrosomia., (Copyright © 2016 Elsevier Ireland Ltd.
