Chronic oral etoposide appears to be an active and well-tolerated regimen in MBC patients previously exposed to chemotherapy. This schedule of etoposide administration warrants further studies, alone or in combination, in MBC.

Stakeholders fundamentally shape the success of wildlife management, yet little is known about how one of the most important stakeholder groups, wildlife agency decision makers, view emerging conservation challenges. Wildlife agency decision makers collectively shape how wildlife conservation unfolds in North America, but their perspectives are generally absent in the literature. Challenges including climate change, conservation funding models, and wildlife disease make understanding how wildlife decision makers view the future of wildlife conservation essential. We interviewed 48 directors and supervisory board members of wildlife agencies in the southeast United States from July 2019 to January 2020 to gauge their assessment of future conservation challenges and preferred response strategies. Declining agency relevancy and insufficient funding were the 2 most commonly identified challenges, while climate change was rarely mentioned as an issue because decision makers believed it was a relatively slowmoving background condition. Decision makers described improving relevance through education and outreach as their primary response to conservation challenges. Our results suggest that climate change-informed wildlife management may benefit from a 2-pronged approach. First, we suggest decision makers should be informed about the challenges posed by climate change, and second, existing efforts to

In response to the 2010 earthquake and subsequent cholera epidemic, St Luke’s Medical Center was established in Port-au-Prince, Haiti. Here, we describe its inception and evolution to include an intensive care unit and two operating rooms, as well as the staffing, training and experiential learning activities, which helped St Luke’s become a sustainable surgical resource. We describe a three-phase model for establishing a sustainable surgical centre in Haiti (build facility and acquire equipment; train staff and perform surgeries; provide continued education and expansion including regular specialist trips) and we report a progressive increase in the number and complexity of cases performed by all-Haitian staff from 2012 to 2022. The results are generalised in the context of the ‘delay framework’ to global health along with a discussion of the application of this three-phase model to resource-limited environments. We conclude with a brief description of the formation of a remote surgical centre in Port-Salut, an unforeseen benefit of local competence and independence. Establishing sustainable and collaborative surgery centres operated by local staff accelerates the ability of resource-limited countries to meet high surgical burdens.

Background Measurement of residual disease following neoadjuvant chemotherapy that accurate predicts long-term survival in locally advanced breast cancer (LABC) is an essential requirement for new drugs efficacy evaluation. Several methods to assess neoadjuvant chemotherapy tumor response have been described. However, to our knowledge, agreement between methods and correlation with survival in independent prospective cohorts has not been reported. Patients & Methods: In this study we report neoadjuvant chemotherapy tumor response and survival in 151 consecutive LABC patients, included in a neoadjuvant clinical trial (http://www.clinicaltrials.gov; NCT00123929). Patients were randomized to either neoadjuvant docetaxel 100 mg/m2 every 21 days or neoadjuvant doxorubicin 75mg/m2, every 21 days, for 4 cycles. Following surgery, response was established according to three methodologies: the measurement of residual breast cancer burden (RBC) as described by Symman's (Symmans WF et al. J Clin Oncol. 2007;25:4414–22), Miller and Payne classification (Ogston KN et al. Breast. 2003;12:320–7) and RECIST criteria. Regarding to Symmans classification we have evaluate both RBC index, as a continuous variable, and RBC classes as a categorical variable (RBC-0,I,II,III). Kappa Cohen's coefficient (K) was used to test agreement between methods. We assessed the correlation between treatment outcome and overall survival (OS) by calculating the Harrell's C- statistic. Results: Median of follow up was 51.9 months. All three methods showed a moderate capacity to classify patients according to OS. The C-statistic to predict OS was 0.76 (IC: 0.67- 0.84) for RBC index and 0.71 (IC: 0.64−0.78) for RBC classes, 0.68 (IC: 0.58−0.78) for RECIST criteria and 0.69 (0.60−0.78) for Miller and Payne classification. Interesting, we did not encountered any death events within RCB-0 class. No significant differences were found between C-statistic when patients were stratified according to therapy. In order to assess the agreement between techniques, we grouped categories 1 and 2 of Miller and Payne classification in 1 category. The agreement between Miller and Payne classification and Symmans method was very high (K=0.87). In contrast, we found a moderate-fair agreement between Miller and Payne classification and RECIST criteria (K=0.46) and Symmans method and RECIST criteria (K=0.27). Conclusion: All three methods predicted fairly well OS. RCB-0 identified the best outcome group. The agreement between methodologies based in pathology analyses was very high. However, the agreement falls off when these methodologies were compared with RECIST criteria. Citation Information: Cancer Res 2011;71(24 Suppl):Abstract nr P5-11-05.
