Popovici V Abstract The dysfunction of the DNA mismatch repair system results in microsatellite instability (MSI). MSI plays a central role in the development of multiple human cancers. In colon cancer, despite being associated with resistance to 5-fluorouracil treatment, MSI is a favourable prognostic marker. In gastric and endometrial cancers, its prognostic value is not so well established. Nevertheless, recognising the MSI tumours may be important for predicting the therapeutic effect of immune checkpoint inhibitors. Several gene expression signatures were trained on microarray data sets to understand the reg...

Authors: Ravindranath MH, Filippone EJ, Devarajan A, Asgharzadeh S Abstract Cytotoxic NK/CD8+ T cells interact with MHC-I ligands on tumor cells through either activating or inhibiting receptors. One of the inhibitory receptors is CD94/NKG2A. The NK/CD8+ T cell cytotoxic capability is lost when tumor-associated human leukocyte antigen, HLA-E, binds the CD94/NKG2A receptor, resulting in tumor progression and reduced survival. Failure of cancer patients to respond to natural killer (NK) cell therapies could be due to HLA-E overexpression in tumor tissues. Preventing the inhibitory receptor-ligand interaction by eithe...

Authors: Pencheva-Demireva M, El-Darawish Y, Kavaldzhieva K, Mladenov N, Lazarov V, Dimitrova-Dikanarova D, Markova T, Nikolov R, Okamura H Abstract Natural killer (NK) cells can discriminate between normal and cancer cells and are known to directly recognize and kill malignant cells or induce apoptosis. Thus, activation of NK cells is considered as a promising strategy for cancer treatment. However, clinical application has been somewhat limited because of difficulties in the preparation of sufficient number of highly cytotoxic/activated NK cells in vitro. We used cytokine stimulation to provide a suitable environ...

Abstract PROBLEM IDENTIFICATION: The impact of mental health disorders (MHDs) and substance use disorders (SUDs) on healthcare utilization (HCU) in patients with cancer is an understudied phenomenon. LITERATURE SEARCH: A literature search of studies published prior to January 2018 that examined HCU in patients with preexisting MHDs or SUDs diagnosed with cancer was conducted. DATA EVALUATION: The research team evaluated 22 studies for scientific rigor and examined significant trends in HCU, as well as types of the MHD, SUD, and cancer studied. SYNTHESIS: The heterogeneity of HCU outcome measures, MH...

This study provides insight into the experiences of young women living with advanced breast cancer. Because these women may not appear ill to the general population, their needs and struggles are not well understood. The results of this study can be a baseline for additional research and clinical interventions. PMID: 31007263 [PubMed - in process]

Abstract PROBLEM IDENTIFICATION: To evaluate the effects of breathing exercises on dyspnea, six-minute walk distance (6MWD), anxiety, and depression in patients with lung cancer. LITERATURE SEARCH: A systematic literature search of the Cochrane Library, Web of Science, Embase®, PubMed®, Weipu, Wanfang, and Chinese National Knowledge Infrastructure databases was performed for publications dated prior to April 6, 2018. DATA EVALUATION: The meta-analysis was performed using Review Manager and Stata. SYNTHESIS: 15 randomized controlled trials with a total of 870 participants met the inclusion cr...

Abstract OBJECTIVES: To identify groups of participants with high and low levels of stigma and to examine the influence of stigma on social support, social constraints, symptom severity, symptom interference, and quality of life (QOL). SAMPLE & SETTING: 62 individuals with lung cancer were identified and recruited from a comprehensive cancer center in the southeastern United States. METHODS & VARIABLES: Participants completed a questionnaire that included demographic information and measures of stigma, symptom severity and interference, social support, social constraints, and QOL. IBM SPSS Statis...

Abstract OBJECTIVES: To explore the relationships among perceived stress, biomarkers of hypothalamic-pituitary-adrenal (HPA) activity, gonadotropin levels, and anti-Müllerian hormone (AMH) in female childhood cancer survivors (CCSs). SAMPLE & SETTING: 24 female CCSs from the Royal Hospital for Sick Children in Edinburgh, Scotland, were included in the study. METHODS & VARIABLES: Perceived stress was measured using the Perceived Stress Scale. HPA activity was measured using salivary cortisol and hair cortisol. Ovarian function was measured using serum gonadotropin levels and serum AMH levels....

Abstract OBJECTIVES: To identify the best available dataset that measured the number of nurse practitioners (NPs) and the type of care they provided; patient information, including malignancy type, age, and insurance status; and volume of procedures performed by NPs. SAMPLE & SETTING: All available national datasets that included patients with cancer and provider types. METHODS & VARIABLES: Using prespecified consensus-driven criteria, all available administrative datasets were reviewed. The authors evaluated four that met the inclusion criteria. RESULTS: The authors' analysis identified the...
