Objective To incorporate standardized documentation into an epilepsy clinic and to use these standardized data to compare patients' perception of epilepsy diagnosis to provider documentation. Methods Using quality improvement methodology, we implemented interventions to increase documentation of epilepsy diagnosis, seizure frequency, and type from 49.8% to 70% of adult nonemployee patients seen by 6 providers over 5 months of routine clinical care. The main intervention consisted of an interactive SmartPhrase that mirrored a documentation template developed by the Epilepsy Learning Healthcare System. We assessed the weekly proportion of complete SmartPhrases among eligible patient encounters with a statistical process control chart. check details We used a subset of patients with established epilepsy care linked to existing patient-reported survey data to examine the proportion of patient-to-provider agreement on epilepsy diagnosis (yes vs no/unsure). We also examined sociodemographic and clinical characteristics of patients who disagreed vs agreed with provider's documentation of epilepsy diagnosis. Results The median SmartPhrase weekly completion rate was 78%. Established patients disagreed with providers with respect to epilepsy diagnosis in 18.5% of encounters (κ = 0.13), indicating that they did not have or were unsure if they had epilepsy despite having a provider-documented epilepsy diagnosis. Patients who disagreed with providers were similar to those who agreed with respect to age, sex, ethnicity, marital status, seizure frequency, type, and other quality-of-life measures. Conclusion This project supports the feasibility of implementing standardized documentation of data relevant to epilepsy care in a tertiary epilepsy clinic and highlights an opportunity for improvement in patient-provider communication.Purpose To assess the predictive value of molecular breast cancer subtypes in premenopausal hormone receptor-positive early breast cancer patients who received adjuvant endocrine treatment or chemotherapy. Experimental design Molecular breast cancer subtypes were centrally assessed on whole tumor sections by immunohistochemistry (IHC) in patients of the Austrian Breast and Colorectal Cancer Study Group (ABCSG) Trial 5 who had received either 5 years of tamoxifen/3 years of goserelin or six cycles of cyclophosphamide, methotrexate, and fluorouracil (CMF). Luminal A disease was defined as Ki67 less then 20%, luminal B as Ki67 ≥20%. The luminal B/HER2-positive subtype displayed 3+ HER2-IHC or amplification by ISH. Recurrence-free survival (RFS) and overall survival (OS) were analyzed using Cox models adjusted for clinical and pathological factors. Results 185 (38%), 244 (50%) and 59 (12%) of 488 tumors were classified as luminal A, luminal B/HER2-negative and luminal B/HER2-positive, respectively. Luminal B subtypes were associated with poor outcome. Patients with Luminal B tumors had a significantly shorter RFS (adjusted hazard ratio [HR] for recurrence 2.22, 95% confidence interval [CI] 1.41-3.49, P = 0.001) and OS (adjusted HR for death 3.51, 95% CI 1.80-6.87, P less then 0.001). No interaction between molecular subtypes and treatment was observed (test for interaction P = 0.84 for RFS; P = 0.69 for OS). Conclusion Determination of molecular subtypes by IHC is an independent prognostic factor for recurrence and death in premenopausal women with early-stage, hormone receptor-positive breast cancer but is not predictive for outcome of adjuvant treatment with tamoxifen/goserelin or CMF.Purpose Wild-type IDH-expressing glioblastoma (GBM) is the most common and aggressive primary brain tumor with a median age at diagnosis of ≥65 years. It accounts for ~90% of all GBM and has a median overall survival (OS) of less then 15 months. Although immune checkpoint therapy has achieved remarkable survival benefits in a variety of aggressive malignancies, similar success has yet to be achieved for GBM among phase III clinical trials to-date. Our study aimed to understand the relationship between subject age and immunotherapeutic efficacy as it relates to survival from glioma. Experimental design 1) Clinical data Glioblastoma patient datasets from the cancer genome atlas, Northwestern Medicine Enterprise Data Warehouse, and clinical studies evaluating immune checkpoint blockade (ICB) were stratified by age and compared for OS. 2) Animal models Young, middle-aged and older adult wild-type and IDO knock-out syngeneic mice were intracranially-engrafted CT-2A or GL261 glioma cell lines and treated with or without CTLA-4/PD-L1 mAbs, or radiation, anti-PD-1 mAb and/or a pharmacologic IDO enzyme inhibitor. Results Advanced age was associated with decreased GBM patient survival regardless of treatment with ICB. The advanced age-associated increase of brain IDO expression was linked to the suppression of immunotherapeutic efficacy and was not reversed by IDO enzyme inhibitor treatment. Conclusions Immunosuppression increases in the brain during advanced age and inhibits anti-glioma immunity in older adults. Going-forward, it will be important to fully understand the factors and mechanisms in the elderly brain that contribute to the decreased survival of older GBM patients during treatment with ICB.Purpose ESR1 mutations are acquired frequently in hormone receptor positive (HR+) metastatic breast cancer after prior aromatase inhibitors (AI). We assessed the clinical utility of baseline ESR1 circulating tumor DNA analysis in the two phase III randomised trials of fulvestrant versus exemestane. Patients and methods The phase III EFECT and SoFEA trials randomised patients with HR+ metastatic breast cancer who had progressed on prior non-steroidal AI, between fulvestrant 250mg and exemestane. Baseline serum samples from 227 patients in EFECT, and baseline plasma from 161 patients in SoFEA, were analysed for ESR1mutations by digital PCR. The primary objectives were to assess the impact of ESR1 mutation status on progression-free and overall survival in a combined analysis of both studies. Results ESR1 mutations were detected in 30% (151/383) baseline samples. In patients with ESR1 mutation detected, PFS was 2.4 months (95%CI,2.0-2.6) on exemestane and 3.9 months (95%CI,3.0-6.0) on fulvestrant (HR=0.59, 95%CI,0.
