Advanced Practice Provider Model for Urgent Oncology Care.

Inherent to the cancer disease trajectory are heightened risks for a plethora of comorbid diagnoses. As the treatment landscape for oncology therapeutics continues to rapidly advance, patients are living longer and potentially experiencing more symptoms requiring rapid assessment. Prompt assessment and intervention for cancer or cancer treatment-related symptoms is imperative to achieve patient comfort and obtain the best overall patient outcomes. Traditionally, these patients were frequently referred to the emergency department (ED) when same-day clinic appointments were not obtainable. In order to decrease ED utilization and provide same-day urgent care for oncology patients, the Abramson Cancer Center established an advanced practice provider-led Oncology Evaluation Center where cancer patients are able to receive same-day assessment, symptom relief, and ultimately prevent unnecessary ED visits.

Gastrointestinal stromal tumors and neuroendocrine tumors.

OBJECTIVES: Patients with rare gastrointestinal (GI) malignancies can exhibit unique objective and subjective manifestations. This article is a primer for the fundamental understanding of some of these diseases, namely gastrointestinal stromal tumors (GIST) and gastroenteropancreatic neuroendocrine tumors (NET) and therapeutic strategies. DATA SOURCES: Epidemiologic data, published research reports, national guidelines for oncology practice, and personal experience. CONCLUSION: Despite the rarity of GIST, gastroenteropancreatic neuroendocrine tumors, gastric lymphoma, and adenocarcinoma of the small bowel, oncology nurses must be prepared to effectively assess, plan, and implement care strategies for these patients. IMPLICATIONS FOR NURSING PRACTICE: Caring for patients with uncommon GI malignancies is challenging for oncology nurses whose experience with these tumors is limited. Fundamental knowledge and awareness of resources can help to ensure optimal patient care. Case vignettes illustrate patient presentation and formulation of treatment recommendations.

Potential of Biosimilars to Increase Access to Biologics: Considerations for Advanced Practice Providers in Oncology.

Biosimilars are biologic products that are highly similar, but not identical, to a licensed reference (or "originator") biologic product. These agents have the potential to provide efficiencies and improve access to treatment for patients. Biosimilars are currently available for use in clinical practice, including oncology indications, and several more are in clinical development. Due to several key differences in their fundamental properties, production and manufacturing of biosimilars is more complex compared with that of small-molecule generic drugs. Accordingly, the generic drug approval process is not suitable or transferable to biosimilars, the approval of which involves extensive and thorough comparison with the originator biologic. Advanced practice providers play an important role in evaluating treatment options available to patients, prescribing, patient education, and product monitoring. In order to perform these tasks effectively, advanced practice providers should understand the concepts related to biosimilars in clinical practice, particularly regarding extrapolation to other indications, product labeling, interchangeability between products, and routine pharmacovigilance, among other clinical considerations. However, many health-care providers have limited awareness and minimal experience regarding biosimilars. Thus, the purpose of this review is to provide an overview of biosimilars and discuss the clinical considerations for oncology advanced practice providers concerning these therapies.

Management of treatment-related toxicities in advanced medullary thyroid cancer.

Progress in the treatment of advanced medullary thyroid cancer (MTC) has resulted from the approval of 2 drugs within the past 5 years, vandetanib and cabozantinib. These multikinase inhibitors (MKIs) possess overlapping specificities for multiple kinase targets implicated in the progression of MTC. Both drugs are associated with toxicities, including hypertension, hemorrhage/perforation, diarrhea and other gastrointestinal events, several dermatologic events, and hypothyroidism. In addition, vandetanib is uniquely associated with QTc prolongation through interaction with myocardial potassium channels, and cabozantinib is uniquely associated with hand-foot skin reaction. Treatment-related toxicities occur frequently and can be severe or life-threatening, and patients undergoing long-term treatment will likely experience adverse events (AEs). Here we offer specific practical recommendations for managing AEs commonly occurring with vandetanib and cabozantinib. The recommended approach relies on early recognition and palliation of symptoms, dose interruption, and dose reduction as necessary in order for the patient to maintain the highest tolerable dose for as long as possible and optimal quality of life. Treatment guidelines do not specify a recommended sequence for treating with vandetanib and cabozantinib; however, most patients will receive both drugs during their lifetime. The choice for first-line therapy is individualized after a risk-benefit assessment and depends on physician preference and patient-related factors, such as comorbid conditions. Because most generalist practices may not be familiar with the intricacies of agents such as vandetanib and cabozantinib, we commend that patients with advanced MTC be managed and treated by a thyroid cancer specialist with coordination of care within a multidisciplinary team.

The Challenges of Clinical Research in Rare Cancers: Bevacizumab Use in Low-Grade Serous Ovarian and Primary Peritoneal Cancers.

There are challenges to conducting rare cancer clinical trials due to issues surrounding clinical trial design, patient recruitment, and analysis of the study outcomes. This article highlights the challenges of research and data analysis in rare cancers and proposes future study directions using less traditional approaches.

Use of low-molecular-weight heparins in the treatment and secondary prevention of cancer-associated thrombosis.

OBJECTIVE: To provide oncology nurses with an understanding of the differences between low-molecular-weight heparins and unfractionated heparin, key clinical trial data, and current treatment guidelines. DATA SOURCES: Primary and tertiary literature and the authors' clinical experience. CONCLUSION: The latest American College of Chest Physicians guidelines recommend low-molecular weight heparin for at least the first 3 to 6 months of long-term treatment for most patients with cancer and deep vein thrombosis (DVT; grade 1A). IMPLICATIONS FOR NURSING PRACTICE: Anticoagulant therapy has been found to be the most effective form of treatment for venous thromboembolism in patients with cancer, and oncology nurses play a critical role in the choice of agents, the dispensing of drugs, and the monitoring of ongoing therapy. Vital to that role are an ability to differentiate among the available agents and apply the current practice guidelines based on the clinical trial data.

Management of common adverse events in patients treated with sorafenib: nurse and pharmacist perspective.

Sorafenib, a tyrosine kinase inhibitor, is indicated for the treatment of patients with unresectable hepatocellular carcinoma (HCC) and advanced renal cell carcinoma (RCC). Sorafenib is currently being evaluated in phase II and III trials in various malignancies as a single agent (locally advanced/metastatic radioactive iodine-refractory differentiated thyroid cancer [DTC]), as part of multimodality care (HCC), and in combination with chemotherapies (metastatic breast cancer). Grade 1 and 2 adverse events (AEs) that commonly occur during treatment (ie, dermatologic manifestations, diarrhea, fatigue, and hypertension) should be proactively managed. The goal is to allow patients to remain on their full dose of sorafenib for as long as their treatment is indicated. A combination of early recognition of and intervention for AEs, patient education, and an open dialogue between patients and their multidisciplinary healthcare team, with timely reporting of AEs, will allow for effective management of AEs and minimize the need for sorafenib dose reduction or discontinuation.

Efficacy and cost: avoiding undertreatment of chemotherapy-induced nausea and vomiting.

Although nausea and vomiting occur in patients with cancer for various reasons, chemotherapy-induced nausea and vomiting (CINV) remains one of the most distressing symptoms associated with cancer therapy. Despite advances in the management of that side effect, patients with cancer receiving chemotherapy continue to report CINV. Oncology nurses should be aware of advances in the management of CINV. Healthcare provider perceptions of CINV may not accurately represent actual occurrence of the symptom, and CINV may affect patients' quality of life or even treatment adherence for selected patients. Although evidence-based guidelines are available, not all healthcare providers, including oncology nurses, follow recommendations for prevention of CINV. Inadequately treated CINV can lead to increased resource costs, as well as patient suffering. This article will review the evidence for the cost of inadequately treated CINV, as well as current clinical guidelines for management of this symptom. Oncology nurses are critical in the assessment and management of CINV, as well as in making recommendations for practice improvement.

Dermatologic toxicities in epidermal growth factor receptor and multikinase inhibitors.

Targeted therapies have produced significant treatment advances for patients diagnosed with a variety of tumor types. These therapies are associated with unique dermatologic toxicities that may hamper treatment efforts and cause significant discomfort for patients. Prevention and management of these toxicities can allow patients to remain on therapy and hence receive maximum clinical benefit from the drug.
