A retrospective multicentric observational study of trastuzumab emtansine in HER2 positive metastatic breast cancer: a real- world experience

We addressed trastuzumab emtansine (T-DM1) e cacy in HER2+ metastatic breast cancer patients treated in real-world practice, and its activity in pertuzumab- pretreated patients. We conducted a retrospective, observational study involving 23 cancer centres, and 250 patients. Survival data were analyzed by Kaplan Meier curves and log rank test. Factors testing signi cant in univariate analysis were tested in multivariate models. Median follow-up was 15 months and median T-DM1 treatment-length 4 months. Response rate was 41.6%, clinical bene t 60.9%. Median progression-free and median overall survival were 6 and 20 months, respectively. Overall, no di erences emerged by pertuzumab pretreatment, with median progression-free and median overall survival of 4 and 17 months in pertuzumab- pretreated (p=0.13), and 6 and 22 months in pertuzumab-naïve patients (p=0.27). Patients who received second-line T-DM1 had median progression-free and median overall survival of 3 and 12 months (p=0.0001) if pertuzumab-pretreated, and 8 and 26 months if pertuzumab-naïve (p=0.06). In contrast, in third-line and beyond, median progression-free and median overall survival were 16 and 18 months in pertuzumab- pretreated (p=0.05) and 6 and 17 months in pertuzumab-naïve patients (p=0.30). In multivariate analysis, lower ECOG performance status was associated with progression-free survival bene t (p<0.0001), while overall survival was positively a ected by lower ECOG PS (p<0.0001), absence of brain metastases (p 0.05), and clinical bene t (p<0.0001). Our results are comparable with those from randomized trials. Further studies are warranted to con rm and interpret our data on apparently lower T-DM1 e cacy when given as second-line treatment after pertuzumab, and on the optimal sequence order

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10&nbsp;years; 78.2% included were male with a median age of 37&nbsp;years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

La gestione della sindrome influenzale in Pediatria

Guidelines for the management of influenza in children were developed by the National Institutes for Health (Istituto Superiore di Sanit\ue0) together with all the major Italian paediatric societies. Rapid diagnostic tests are not recommended due to insufficient sensitivity and specificity. Etiological treatment with neuraminidase inhibitors or other antiviral agents is not recommended. Symptomatic treatment should be based on acetaminophen or ibuprofen. Antibiotics are not recommended unless fever persists for more than 7 days and signs of lower respiratory tract infection are present. Admission to hospital should be limited to cases with preexisting risk conditions, young infants with bronchiolitis, cases with respiratory distress and oxygen desaturation, or cases where home management is difficult due to social reasons

Addition of either lonidamine or granulocyte colony-stimulating factor does not improve survival in early breast cancer patients treated with high-dose epirubicin and cyclophosphamide

Purpose : Lonidamine (LND) can enhance the activity of anthracyclines in patients with metastatic breast cancer. A multicenter, prospective, randomized trial was designed to determine whether the association of LND with high-dose epirubicin plus cyclophosphamide (EC) could improve disease-free survival (DFS) in patients with early breast cancer (BC) compared with EC alone. Granulocyte colony-stimulating factor (G-CSF) was added to maintain the EC dose-intensity. Patients and Methods: From October 1991 to April 1994, 506 patients with stage I/II BC Were randomly assigned to four groups: (A) epirubicin 120 mg/m(2) and cyclophosphamide 600 mg/m(2) administered intravenously on day 1 every 21 days for four cycles (124 patients); (B) EC plus LND 450 mg/d administered orally (125 patients); (C) EC plus G-CSF administered subcutaneously (129 patients); (D) EC plus LND plus G-CSF (128 patients). Results: Median follow-up was 55 months. Five-year DFS rate was similar for LND (B+D groups; 69.6%) versus non-LND arms (A+C groups; 70.3%) and G-CSF (C+D groups; 67.2%) versus non-G-CSF arms (A+B groups; 72.9%). Five-year overall survival (OS) was comparable in LND (79.1%) versus nonAND arms (81.3%) and in G-CSF (80.6%) versus non-G-CSF arms (79.6%). DFS and OS distributions in LND and G-CSF arms did not change according to tumor size, node, receptor, and menopausal status. G-CSF dramatically reduced hematologic toxicity without having a significant impact on dose-intensity (98.1% v 95.5% for C+D and A+B groups, respectively). Conclusion: EC is active and well tolerated in patients with. early breast cancer. The addition of LND or G-CSF does not improve DFS or OS. (C) 2003 by American Society of Clinical Oncology
