Overall, RASi may be a promising adjunct in cancer therapy.Inflammatory mediators in tumor microenvironment influence cancer occurrence, growth and metastasis through complex signaling networks. Excessive inflammation is closely associated with elevated cancer risk and mortality, in part through inflammation-induced angiogenesis. Mechanistically, multiple tumor-associated inflammatory cells increase the release and accumulation of various inflammatory products in cancerous sites. These products in turn activate tumor associated signaling cascades such as STAT3, NF-κB, PI3K/Akt and p38 MAPK, which mediate the recruitment of inflammatory cells and secretion of pro-inflammatory factors. More importantly, these events promote the secretion of various pro-angiogenesis factors from endothelial, tumor and inflammatory cells, which then drive malignancy in endothelial cells in a paracrine and/or autocrine manner. Its ultimate effect is to promote endothelial cell proliferation, migration, survival and tube formation, and to hence the formation of blood vessels in tumors. This review describes the signaling network that connects the interaction between inflammation and cancer, especially those involved in inflammation-induced angiogenesis. This will reveal potential targets for the design of anti-inflammatory treatments and drugs that inhibites tumor growth and angiogenesis.Practitioners face significant challenges when evaluating patients with cancer who suffer from back pain. Back pain is one of the most common reasons for patients to visit medical providers. This case study will review a patient with cancer presenting with atypical radicular pain.In the United States, 1 in 8 women will be diagnosed with invasive breast cancer in her lifetime. Breast cancer death rates are higher for women in the United States than any other cancer, followed by lung cancer (National Cancer Institute, 2019). More than 70% of breast cancers are hormone receptor (HR)-positive and human epidermal growth factor receptor 2 (HER2)-negative, and of those patients, 40% have driver mutations in the gene phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) resulting in damaged phosphatidylinositol 3-kinase (PI3K) and uncontrolled cell growth (Mollon et al., 2018; Setiawan et al., 2009). These patients are initially treated with endocrine therapy, but resistance remains an issue.  https://www.selleckchem.com/products/pt2385.html  Inhibition of PI3K is a promising new approach to overcome resistance to endocrine therapy in breast cancer. Previous trials of PI3K inhibitors (pictilisib [GDC-0941], buparlisib [BMK120], and taselisib [GDC-0032]) in breast cancer have shown little efficacy secondary to toxicities due to their nonselectivity to PI3K subunits. Alpelisib is a selective inhibitor of PI3K for patients with HR-positive, HER2-negative, PIK3CA-mutated breast cancer who have progressed on endocrine therapy. This drug review will discuss the pharmacology of alpelisib, current data supporting its place in therapy, management of adverse events, and the clinical implications for advanced practitioners treating patients with HR-positive, HER2-negative breast cancer.As the health-care industry continues to be pushed to find new, innovative ways to deliver quality care with an emphasis on enhancing quality of life, the use of advanced practice providers and telemedicine technology are two promising developments at the forefront of this new era. Advanced practice providers have been shown to provide highly effective, quality patient care. They often deliver this care at a decreased cost to the patient and healthcare system. Telemedicine technology allows providers to access patients through new, patient-centered avenues, thus enhancing their healthcare experience. Advanced practice providers are well equipped to apply telemedicine technology to expand access to care and innovate new care delivery models. This article describes the design and implementation of a novel telemedicine care model within a malignant hematologic team.Evidenced-based practice requires timely and accurate integration of scientific advances. This presents a challenge for the oncology clinician given the robust pace of scientific discovery and the increasing number of new drug approvals and expanded indications for previously approved drugs. All currently available antineoplastic therapies have been developed through the clinical trials process. Advanced practitioners (APs) in oncology are often involved in the conduct of clinical trials as primary investigators, sub-investigators, study coordinators, or in the delivery and monitoring of care to patients enrolled in these trials. A prerequisite to evidenced-based practice is understanding how clinical trials are conducted and how to critically analyze published results of studies leading to U.S. Food & Drug Administration approval. Any AP involved in the clinical management and supportive care of patients receiving antineoplastic therapies should be able to critically review published data to glean findings that warrant a change in practice. The goals of this manuscript are to summarize key elements of the clinical trial process for oncology drug development and approval in the United States and to provide a primer for the interpretation of clinical data.Traditionally, treatment responses to chemotherapy had been based on Response Evaluation Criteria in Solid Tumours (RECIST) criteria evaluating tumor shrinkage, stabilization of disease, growth, or development of new metastatic lesions. Using the same criteria to determine response in patients on immunotherapy has proven difficult, as some patients have initial growth of disease or develop new small metastatic lesions. The phenomenon of pseudoprogression is the initial growth of a primary lesion followed by latent or delayed response. Advanced practitioners need to be aware of the possibility of pseudoprogression in order to educate patients and help them stay on effective treatment.Cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors in combination with endocrine therapy are a preferred treatment option for premenopausal and postmenopausal women with hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer (mBC). Palbociclib is a potent, first-in-class oral inhibitor of CDK4/6. To provide optimal care to patients with HR+/HER2- mBC receiving palbociclib, advanced practitioners require a thorough understanding of the efficacy and adverse event (AE) profile of palbociclib as well as the diverse characteristics and support needs of patients eligible for palbociclib treatment. This Grand Rounds uses two hypothetical patient scenarios to illustrate core issues in the management of premenopausal and postmenopausal patients receiving palbociclib-based therapy for mBC. In addition to providing an overview of key efficacy and safety data, each case offers practical guidance on providing individualized, patient-centered care, the identification and management of treatment-related AEs, management of concomitant medications, and best practices to promote adherence to therapy.
