Abstract
Abstract
BACKGROUND: The real-world impact of CDK4/6 inhibitor use on HR+/HER2- mBC treatment sequencing, treatment response, and therapeutic utilization is limited. This study sought to describe treatment sequencing and response pre- and post-FDA approval of CDK4/6 inhibitors by conducting a traditional observational study approach and supplementing with a machine-learning methodology.
METHODS: Female patients ≥18yrs were identified in the MarketScan Commercial and Medicare Supplement databases with continuous enrollment for at least 12 months pre-index, ≥2 medical claims for a BC diagnosis and ≥2 medical claims for metastatic disease (earliest=index date), and who had no treatment at any time with HER2 targeted therapy. Patients were excluded if they had received CDK4/6 or everolimus treatment prior to index. Treatment was stratified by line of therapy pre- and post- first CDK4/6 approval (February 3, 2015). We identified treatment patterns with standard distributions and visual analytics. Response to therapy and utilization was analyzed with prediction models and IBM Watson® machine learning population comparison models.
RESULTS: A total of 19,558 patients were eligible for the study with a mean age at diagnosis of mBC of 62 (SD 13). Prior to first CDK4/6 inhibitor approval, anastrazole and letrozole monotherapies were most likely to be identified as both first and second line treatment. Following approval of the first CDK4/6 inhibitor in 2015, CDK4/6 inhibitors were observed as a first line treatment in 25% of patients, and as second line treatment in 24% of patients. Of patients diagnosed following the first CDK4/6 inhibitor approval, 44% of patients were exposed to endocrine therapy and 10% were exposed to chemotherapy in the pre-index period. Patients receiving CDK4/6 inhibitors in combination with endocrine therapy as first line treatment were observed to have a longer progression free survival time than patients receiving endocrine monotherapy. Visual analytics demonstrate a large variation in treatment sequencing, especially after first line therapy. Machine learning and prediction models identified a strong secular bias in the use of CDK4/6 and a signal for improved treatment response in patients with no exposure to endocrine therapies in the pre-index period.
CONCLUSIONS: The mBC treatment landscape has changed significantly with the introduction of CDK4/6 inhibitors, which may be expected to impact long-term outcomes. Visual analytics and machine learning approaches can improve clinical insight. These approaches can help with identifying patient and clinical characteristics that predict response and utilization as well as appropriate treatment selections across lines of therapy.

Abstract
This study assessed the effects of multiplex genetic testing on disease risk perceptions among 216 healthy adults. Participants, aged 25-40, were recruited through the Multiplex Initiative, which offered a genetic susceptibility test for eight common diseases. Participants completed baseline telephone and web-based surveys prior to making the testing decision. Three months after the receipt of mailed test results, participants completed a follow-up telephone survey. Risk perceptions for the eight diseases were measured at baseline and follow-up, along with beliefs about genetic causation of those diseases. The main results were: (i) mean risk perceptions were considerably stable from baseline to follow-up; (ii) the best predictors of follow-up risk perceptions were the corresponding baseline perceptions and family history; and (iii) within-individuals, most participants increased or decreased their risk perceptions for specific diseases in concordance with the number of risk markers they carry, their family history and their beliefs about genetic causality of diseases. In conclusion, participants presented a vigilant approach to the interpretation of genetic test results, which provides reassurance with regard to a potential inflation of risk perceptions in the population because of multiplex genetic testing.

Abstract
e17041 Background: Although treatment effects and toxicities have been reported from randomized clinical trials of patients with squamous cell carcinoma of the head and neck (SCCHN), little information is available from real-world clinical practice where heterogeneous treatment patterns and patient populations may lead to different estimates than those observed in clinical trials. Methods: Using a population-based tumor registry at a large, Midwestern integrated health system, we identified all cases of stage III or IV SCCHN diagnosed 2000–2006. The incidence/severity of acute and late toxicities associated with SCCHN treatment was obtained from detailed medical record review of health system encounters, including physician notes. Grading of toxicities (using CTCAE3 criteria), distinction between acute and late toxicity, and analyses by treatment are ongoing. The incidence and severity of toxicities will be presented by treatment regimen, tumor location and tumor stage. We presented here an interim analysis. Results: Among the target population of 194 patients that will ultimately be included in this study, 137 medical record reviews have been completed to date. The percentages of patients with toxicities, including 95% confidence intervals are presented in the table , below. Conclusions: Toxicity in patients with advanced SCCHN is common. Data from clinical practice quantifying the incidence are lacking, these data from an observational real-world study provide important baseline information on the incidence of toxicities in patients with advanced SCCHN and also call for safer effective treatment for SCCHN.
