Defining D-irAEs: consensus-based disease definitions for the diagnosis of dermatologic adverse events from immune checkpoint inhibitor therapy.

With an increasing number of patients eligible for immune checkpoint inhibitors, the incidence of immune-related adverse events (irAEs) is on the rise. Dermatologic immune-related adverse events (D-irAEs) are the most common and earliest to manifest, often with important downstream consequences for the patient. Current guidelines lack clarity in terms of diagnostic criteria for D-irAEs. The goal of this project is to better define D-irAE for the purposes of identification, diagnosis, and future study of this important group of diseases.The objectives of this project were to develop consensus guidance for an approach to D-irAEs including disease definitions and severity grading. Knowing that consensus among oncologists, dermatologists, and irAE subspecialists would be critical for usability, we formed a Dermatologic irAE Disease Definition Panel. The panel was composed of 34 experts, including oncologists, dermatologists, a rheumatologist, and an allergist/immunologist from 22 institutions across the USA and internationally. A modified Delphi consensus process was used, with two rounds of anonymous ratings by panelists and two virtual meetings to discuss areas of controversy. Panelists rated content for usability, appropriateness, and accuracy on 9-point scales in electronic surveys and provided free text comments. A working group aggregated survey responses and incorporated them into revised definitions. Consensus was based on numeric ratings using the RAND/UCLA Appropriateness Method with prespecified definitions.Following revisions based on panelist feedback, all items received consensus in the second round of ratings. Consensus definitions were achieved for 10 core D-irAE diagnoses: ICI-vitiligo, ICI-lichen planus, ICI-psoriasis, ICI-exanthem, ICI-bullous pemphigoid, ICI-Grover's, ICI-eczematous, ICI-eruptive atypical squamous proliferation, ICI-pruritus without rash, and ICI-erosive mucocutaneous. A standard evaluation for D-irAE was also found to reach consensus, with disease-specific exceptions detailed when necessary. Each disorder's description includes further details on disease subtypes, symptoms, supportive exam findings, and three levels of diagnostic certainty (definite, probable, and possible).These consensus-driven disease definitions standardize D-irAE classification in a useable framework for multiple disciplines and will be the foundation for future work. Given consensus on their accuracy and usability from a representative panel group, we anticipate that they can be used broadly across clinical and research settings.

Society for Immunotherapy of Cancer (SITC) clinical practice guideline on immunotherapy for the treatment of melanoma, version 3.0.

Since the first approval for immune checkpoint inhibitors (ICIs) for the treatment of cutaneous melanoma more than a decade ago, immunotherapy has completely transformed the treatment landscape of this chemotherapy-resistant disease. Combination regimens including ICIs directed against programmed cell death protein 1 (PD-1) with anti-cytotoxic T lymphocyte antigen-4 (CTLA-4) agents or, more recently, anti-lymphocyte-activation gene 3 (LAG-3) agents, have gained regulatory approvals for the treatment of metastatic cutaneous melanoma, with long-term follow-up data suggesting the possibility of cure for some patients with advanced disease. In the resectable setting, adjuvant ICIs prolong recurrence-free survival, and neoadjuvant strategies are an active area of investigation. Other immunotherapy strategies, such as oncolytic virotherapy for injectable cutaneous melanoma and bispecific T-cell engager therapy for HLA-A*02:01 genotype-positive uveal melanoma, are also available to patients. Despite the remarkable efficacy of these regimens for many patients with cutaneous melanoma, traditional immunotherapy biomarkers (ie, programmed death-ligand 1 expression, tumor mutational burden, T-cell infiltrate and/or microsatellite stability) have failed to reliably predict response. Furthermore, ICIs are associated with unique toxicity profiles, particularly for the highly active combination of anti-PD-1 plus anti-CTLA-4 agents. The Society for Immunotherapy of Cancer (SITC) convened a panel of experts to develop this clinical practice guideline on immunotherapy for the treatment of melanoma, including rare subtypes of the disease (eg, uveal, mucosal), with the goal of improving patient care by providing guidance to the oncology community. Drawing from published data and clinical experience, the Expert Panel developed evidence- and consensus-based recommendations for healthcare professionals using immunotherapy to treat melanoma, with topics including therapy selection in the advanced and perioperative settings, intratumoral immunotherapy, when to use immunotherapy for patients with BRAFV600-mutated disease, management of patients with brain metastases, evaluation of treatment response, special patient populations, patient education, quality of life, and survivorship, among others.

Benefit and toxicity of programmed death-1 blockade vary by ethnicity in patients with advanced melanoma: an international multicentre observational study.

BACKGROUND: Programmed cell death receptor-1 (PD-1) monotherapy is a standard treatment for advanced cutaneous melanoma, but its efficacy and toxicity are defined in white populations and remain poorly characterized in other ethnic groups, such as East Asian, Hispanic and African. OBJECTIVES: To determine the efficacy and toxicity of PD-1 monotherapy in different ethnic groups. METHODS: Clinical data for patients with unresectable or advanced melanoma treated with anti-PD-1 monotherapy between 2009 and 2019 were collected retrospectively from five independent institutions in the USA, Australia and China. Tumour response, survival and immune-related adverse events (irAEs) were compared by ethnicity (white vs. East Asian/Hispanic/African) across different melanoma subtypes: nonacral cutaneous (NAC)/unknown primary (UP) and acral/mucosal/uveal. RESULTS: In total, 1135 patients were included. White patients had significantly higher objective response rate (ORR) [54%, 95% confidence interval (CI) 50-57% vs. 20%, 95% CI 13-28%; adjusted P < 0·001] and longer progression-free survival (14·2 months, 95% CI 10·7-20·3 vs. 5·4 months, 95% CI 4·5-7·0; adjusted P < 0·001) than East Asian, Hispanic and African patients in the NAC and UP subtypes. White ethnicity remained independently associated with a higher ORR (odds ratio 4·10, 95% CI 2·48-6·81; adjusted P < 0·001) and longer PFS (hazard ratio 0·58, 95% CI 0·46-0·74; adjusted P < 0·001) in multivariate analyses after adjustment for age, sex, primary anatomical location, metastasis stage, baseline lactate dehydrogenase level, mutational status and prior systemic treatment. White and East Asian/Hispanic/African patients shared similar ORR and progression-free survival in acral/mucosal/uveal melanomas. Similar melanoma-subtype-specific ethnic discrepancies were observed in complete response rate and overall survival. White patients had higher rates of gastrointestinal irAEs but lower rates of endocrine, liver and other rare types of irAEs. These differences in irAEs by ethnicity were not attributable to varying melanoma subtypes. CONCLUSIONS: Ethnic discrepancy in clinical benefit is specific to melanoma subtype, and East Asian, Hispanic and African patients with NAC and UP melanomas have poorer clinical benefits than previously recognized. The ethnic discrepancy in toxicity observed across different melanoma subtypes warrants an ethnicity-based irAE surveillance strategy. More research is needed to elucidate the molecular and immunological determinants of these differences. What is already known about this topic? There is a great difference in response to immunotherapy between different subtypes of melanoma (cutaneous, mucosal, acral and uveal) in patients with advanced disease. What does this study add? Our data show for the first time that there are differences between different ethnic groups in terms of both response and toxicity to immunotherapy beyond the well-appreciated discrepancies due to melanoma subtype.

Early Use of High-Dose Glucocorticoid for the Management of irAE Is Associated with Poorer Survival in Patients with Advanced Melanoma Treated with Anti-PD-1 Monotherapy.

PURPOSE: Programmed cell death receptor-1 (PD-1) inhibitors are frontline therapy in advanced melanoma. Severe immune-related adverse effects (irAEs) often require immunosuppressive treatment with glucocorticoids (GCCs), but GCC use and its correlation with patient survival outcomes during anti-PD-1 monotherapy remains unclear. EXPERIMENTAL DESIGN: In this multicenter retrospective analysis, patients treated with anti-PD-1 monotherapy between 2009 and 2019 and detailed GCC use, data were identified from five independent cohorts, with median follow-up time of 206 weeks. IrAEs were tracked from the initiation of anti-PD-1 until disease progression, initiation of a new therapy, or last follow-up. Correlations between irAEs, GCC use, and survival outcomes were analyzed. RESULTS: Of the entire cohort of 947 patients, 509 (54%) developed irAEs. In the MGH cohort [irAE(+) n = 90], early-onset irAE (within 8 weeks of anti-PD-1 initiation) with high-dose GCC use (≥60-mg prednisone equivalent once a day) was independently associated with poorer post-irAE PFS/OS (progression-free survival/overall survival) [post-irAE PFS: HR, 5.37; 95% confidence interval (CI), 2.10-13.70; P < 0.001; post-irAE OS: HR, 5.95; 95% CI, 2.20-16.09; P < 0.001] compared with irAEs without early high-dose GCC use. These findings were validated in the combined validation cohort [irAE(+) n = 419, post-irAE PFS: HR, 1.69; 95% CI, 1.04-2.76; P = 0.04; post-irAE OS: HR, 1.97; 95% CI, 1.15-3.39; P = 0.01]. Similar findings were also observed in the 26-week landmark analysis for post-irAE-PFS but not for post-irAE-OS. A sensitivity analysis using accumulated GCC exposure as the measurement achieved similar results. CONCLUSIONS: Early high-dose GCC use was associated with poorer PFS and OS after irAE onset. Judicious use of GCC early during anti-PD-1 monotherapy should be considered. Further prospective randomized control clinical trials designed to explore alternative irAE management options are warranted.

Society for Immunotherapy of Cancer (SITC) clinical practice guideline on immunotherapy for the treatment of breast cancer.

Breast cancer has historically been a disease for which immunotherapy was largely unavailable. Recently, the use of immune checkpoint inhibitors (ICIs) in combination with chemotherapy for the treatment of advanced/metastatic triple-negative breast cancer (TNBC) has demonstrated efficacy, including longer progression-free survival and increased overall survival in subsets of patients. Based on clinical benefit in randomized trials, ICIs in combination with chemotherapy for the treatment of some patients with advanced/metastatic TNBC have been approved by the United States (US) Food and Drug Administration (FDA), expanding options for patients. Ongoing questions remain, however, about the optimal chemotherapy backbone for immunotherapy, appropriate biomarker-based selection of patients for treatment, the optimal strategy for immunotherapy treatment in earlier stage disease, and potential use in histological subtypes other than TNBC. To provide guidance to the oncology community on these and other important concerns, the Society for Immunotherapy of Cancer (SITC) convened a multidisciplinary panel of experts to develop a clinical practice guideline (CPG). The expert panel drew upon the published literature as well as their clinical experience to develop recommendations for healthcare professionals on these important aspects of immunotherapeutic treatment for breast cancer, including diagnostic testing, treatment planning, immune-related adverse events (irAEs), and patient quality of life (QOL) considerations. The evidence-based and consensus-based recommendations in this CPG are intended to give guidance to cancer care providers treating patients with breast cancer.

Consensus disease definitions for neurologic immune-related adverse events of immune checkpoint inhibitors.

Expanding the US Food and Drug Administration-approved indications for immune checkpoint inhibitors in patients with cancer has resulted in therapeutic success and immune-related adverse events (irAEs). Neurologic irAEs (irAE-Ns) have an incidence of 1%-12% and a high fatality rate relative to other irAEs. Lack of standardized disease definitions and accurate phenotyping leads to syndrome misclassification and impedes development of evidence-based treatments and translational research. The objective of this study was to develop consensus guidance for an approach to irAE-Ns including disease definitions and severity grading. A working group of four neurologists drafted irAE-N consensus guidance and definitions, which were reviewed by the multidisciplinary Neuro irAE Disease Definition Panel including oncologists and irAE experts. A modified Delphi consensus process was used, with two rounds of anonymous ratings by panelists and two meetings to discuss areas of controversy. Panelists rated content for usability, appropriateness and accuracy on 9-point scales in electronic surveys and provided free text comments. Aggregated survey responses were incorporated into revised definitions. Consensus was based on numeric ratings using the RAND/University of California Los Angeles (UCLA) Appropriateness Method with prespecified definitions. 27 panelists from 15 academic medical centers voted on a total of 53 rating scales (6 general guidance, 24 central and 18 peripheral nervous system disease definition components, 3 severity criteria and 2 clinical trial adjudication statements); of these, 77% (41/53) received first round consensus. After revisions, all items received second round consensus. Consensus definitions were achieved for seven core disorders: irMeningitis, irEncephalitis, irDemyelinating disease, irVasculitis, irNeuropathy, irNeuromuscular junction disorders and irMyopathy. For each disorder, six descriptors of diagnostic components are used: disease subtype, diagnostic certainty, severity, autoantibody association, exacerbation of pre-existing disease or de novo presentation, and presence or absence of concurrent irAE(s). These disease definitions standardize irAE-N classification. Diagnostic certainty is not always directly linked to certainty to treat as an irAE-N (ie, one might treat events in the probable or possible category). Given consensus on accuracy and usability from a representative panel group, we anticipate that the definitions will be used broadly across clinical and research settings.

Immune Checkpoint Inhibitor-Based Therapy as a Backbone in Cancer Treatment.

At JADPRO Live 2019, Krista M. Rubin, MS, FNP-BC, and Anthony J. Olszanski, MD, RPh, reviewed the basic concepts of immunotherapy and the current treatment landscape, and discussed emerging data for immune checkpoint inhibitor-based combinations that are being explored in late-stage clinical trials.

Caring for Patients Treated With Checkpoint Inhibitors for the Treatment of Metastatic Merkel Cell Carcinoma.

OBJECTIVE: To provide an overview for oncology nurses about Merkel cell carcinoma and its management with immunotherapy. DATA SOURCES: A literature search was conducted from 2013 to the present using search terms including "Merkel cell carcinoma," "avelumab," "pembrolizumab," "immune-mediated adverse events," and "infusion-related reactions." Clinical experience of the authors was also considered. CONCLUSION: Oncology nurses can expect to manage an increasing number of patients with Merkel cell carcinoma because of increased incidence of the disease, as well as evolving immunotherapy treatment paradigms. Both avelumab and pembrolizumab possess favorable safety profiles but are associated with immune-mediated and infusion-related reactions. IMPLICATIONS FOR NURSING PRACTICE: Oncology nurses need to understand Merkel cell carcinoma and be able to recognize the signs and symptoms of immune-mediated adverse events and infusion-related reactions associated with treatment to provide early intervention.

Meeting the Challenge of Immune-Related Adverse Events With Optimized Telephone Triage and Dedicated Oncology Acute Care.

Immune checkpoint inhibitors (ICIs) have improved outcomes for many patients with advanced cancers. However, managing the immune-related adverse events (irAEs) associated with these agents is challenging. Late recognition and/or inadequate irAE management can result in ICI discontinuation or termination, negatively impacting patient outcomes and increasing unplanned emergency department visits, hospital admissions, and costs of care. Improved clinician training and infrastructure development are needed to adequately address irAEs and maximize the potential benefits of ICIs. Advanced practice providers (APPs) are well positioned to drive these improvements. Two aspects of care may reduce the burden of irAE management: improved telephone triage and the implementation of dedicated oncology acute care services. Evidence-based protocols should be used for telephone triage. Protocol development may benefit from an evaluation of current irAE management guidelines together with resources from the Melanoma Nursing Initiative and Immuno-Oncology Essentials. Patients and their caregivers must be educated to recognize and report early symptoms suggestive of an irAE, thereby supporting triage efforts. Advanced practice providers should also advocate for the development of dedicated oncology acute care facilities staffed with clinicians well trained to recognize, grade, and manage irAEs. This manuscript reviews multiple existing models of telephone triage and dedicated oncology acute care. Oncology APPs are poised to lead the staffing, infrastructure, and educational changes necessary to reduce the burden of irAEs in patients receiving ICI therapy.

An update on the Society for Immunotherapy of Cancer consensus statement on tumor immunotherapy for the treatment of cutaneous melanoma: version 2.0.

BACKGROUND: Cancer immunotherapy has been firmly established as a standard of care for patients with advanced and metastatic melanoma. Therapeutic outcomes in clinical trials have resulted in the approval of 11 new drugs and/or combination regimens for patients with melanoma. However, prospective data to support evidence-based clinical decisions with respect to the optimal schedule and sequencing of immunotherapy and targeted agents, how best to manage emerging toxicities and when to stop treatment are not yet available. METHODS: To address this knowledge gap, the Society for Immunotherapy of Cancer (SITC) Melanoma Task Force developed a process for consensus recommendations for physicians treating patients with melanoma integrating evidence-based data, where available, with best expert consensus opinion. The initial consensus statement was published in 2013, and version 2.0 of this report is an update based on a recent meeting of the Task Force and extensive subsequent discussions on new agents, contemporary peer-reviewed literature and emerging clinical data. The Academy of Medicine (formerly Institute of Medicine) clinical practice guidelines were used as a basis for consensus development with an updated literature search for important studies published between 1992 and 2017 and supplemented, as appropriate, by recommendations from Task Force participants. RESULTS: The Task Force considered patients with stage II-IV melanoma and here provide consensus recommendations for how they would incorporate the many immunotherapy options into clinical pathways for patients with cutaneous melanoma. CONCLUSION: These clinical guidleines provide physicians and healthcare providers with consensus recommendations for managing melanoma patients electing treatment with tumor immunotherapy.

MAPK Pathway-Targeted Therapies: Care and Management of Unique Toxicities in Patients With Advanced Melanoma
.

BACKGROUND: Agents targeting the MAPK pathway, including inhibitors of BRAF and MEK, have dramatically transformed the treatment landscape for patients with BRAF-mutant metastatic melanoma. Although generally well tolerated, targeted agents were associated with unique toxicities.
. OBJECTIVES: This article aims to provide nurses with an overview of the key toxicities and associated management strategies of the characteristic adverse event (AE) profile associated with agents targeting the MAPK pathway.
. METHODS: Data from clinical trials evaluating vemurafenib, dabrafenib, trametinib, and cobimetinib were reviewed and summarized along with research on management of AEs identified in clinical trials.
. FINDINGS: The key AEs associated with these agents included pyrexia and cutaneous toxicities. Other notable AEs included arthralgias, ocular toxicities, and cardiac events. Because these agents are administered until progressive disease or unacceptable toxicity, nurses should be aware of management strategies to optimize treatment outcomes.

Advances in Melanoma: The Rationale for the Melanoma Nursing Initiative
.

This article provides an overview of this supplement, outlining the needs assessment process the Melanoma Nursing Initiative (MNI) used to determine the immunotherapy and targeted therapy topics for discussion as well as the process for developing the consensus statements. The article provides specific discussion of a unique feature of the MNI, the care step pathways (CSPs) for management of adverse events (AEs) associated with melanoma therapies, and looks to the future in terms of the potential benefits of engaging and enabling oncology nurses to adopt a standardized approach to AE management and adherence promotion for melanoma therapies.

PD-1 Inhibitor Therapy: Consensus Statement From the Faculty of the Melanoma Nursing Initiative on Managing Adverse Events
.

BACKGROUND: Programmed cell death protein 1 (PD-1) inhibitor therapies are now a standard treatment for advanced melanoma and other tumor types. The immune-related adverse events (irAEs) associated with PD-1 inhibitor therapy are drastically different from the AEs associated with chemotherapy. Because these irAEs reflect immune system activation rather than side effects of therapy, nurses should be cognizant of the range of organ systems potentially affected as well as likely clinical presentations.
. OBJECTIVES: This article presents consensus statements to guide nurses in the recognition and management of irAEs associated with PD-1 inhibitor monotherapy for advanced melanoma.
. METHODS: Members of the Melanoma Nursing Initiative discussed the current literature and clinical experience regarding nursing interventions related to irAEs associated with PD-1 inhibitor therapy.
. FINDINGS: The care step pathways provided for select irAEs represent a proactive, comprehensive nursing care plan to support optimal outcomes for patients receiving PD-1 inhibitor therapy.

A phase 2 trial of dasatinib in patients with locally advanced or stage IV mucosal, acral, or vulvovaginal melanoma: A trial of the ECOG-ACRIN Cancer Research Group (E2607).

BACKGROUND: KIT-directed tyrosine kinase inhibitors such as imatinib have demonstrated benefits in KIT-mutant (KIT+) mucosal, acral, vulvovaginal, and chronically sun-damaged (CSD) melanoma. Dasatinib has superior preclinical activity in comparison with other tyrosine kinase inhibitors against cells with the most common KIT mutation, exon 11L576P . The ECOG-ACRIN E2607 trial assessed dasatinib in patients with these melanoma subtypes. METHODS: Patients received 70 mg of oral dasatinib twice daily. The primary objective for this 2-stage phase 2 trial was response rate. Stage I was open to KIT+ and wild-type KIT (KIT-) mucosal, acral, and CSD melanoma (n = 57). Stage II accrued only KIT+ tumors (n = 30). To enrich the trial for KIT+ tumors, vulvovaginal melanoma was added, and CSD melanoma was removed from eligibility. Secondary objectives included progression-free survival (PFS), overall survival (OS), and safety. RESULTS: From May 2009 to December 2010, the first stage enrolled 57 patients. Among the evaluable patients, 3 of 51 (5.9%) achieved a partial response: all were KIT-. Stage II closed early because of slow accrual (November 2011 to December 2015). In stage II, 4 of 22 evaluable patients (18.2%) had a partial response; the median duration was 4.2 months. The median PFS was 2.1 months (n = 73; 95% confidence interval [CI], 1.5-2.9 months). The median OS was 7.5 months (95% CI, 6.0-11.9 months). In exploratory analyses, no differences were seen in PFS or OS with the KIT status or subtype. Dasatinib was discontinued because of adverse events in 9 of 75 patients (12%). CONCLUSIONS: The dasatinib response rate among KIT+ melanoma patients was low. In view of its clinical activity, it is recommended that imatinib remain the KIT tyrosine kinase inhibitor of choice for unresectable KIT+ melanoma.

Understanding Immune Checkpoint Inhibitors for Effective Patient Care.

BACKGROUND: Immune checkpoint inhibitors represent a paradigm change in the treatment of melanoma and other advanced cancers. These agents manipulate key immune-regulating pathways to restore immune responses against tumors. The success of this approach is demonstrated by ipilimumab (Yervoy®) for the treatment of advanced melanoma, with improvement in three-year survival rates of about 20%. Newer checkpoint inhibitors targeting the programmed death-1 (PD-1) pathway have been approved and may have higher response rates and improved tolerability. OBJECTIVES: This article aims to educate nurses and increase their comfort level with these new therapies. METHODS: The mechanism of action of immune checkpoint inhibitors is reviewed, and insight is provided on how nurses can use this knowledge to more effectively care for patients receiving these therapies. FINDINGS: The use of immuno-oncology agents is increasing. Oncology nurses must understand the basic immune mechanism of action responsible for the novel toxicity profile characterized by immune-related adverse events (irAEs) and clinical response patterns. Managing irAEs with immune checkpoint inhibitors is not necessarily more difficult than with conventional agents, but a difference does exist. Nurses and other healthcare providers must consider the underlying cause of toxicity with immune checkpoint inhibitors when making management decisions.

Management of primary cutaneous and metastatic melanoma.

OBJECTIVES: To review the diagnosis, staging, and treatments (both standard and novel) for advanced melanoma and discuss the nursing role in the care of patients with melanoma. DATA SOURCES: Published research and education articles, on-line journals, recent texts, and references from pertinent articles. CONCLUSION: Most melanomas are diagnosed at early localized stages when surgery alone can be curative. For patients diagnosed with metastatic disease, treatment options have been limited and generally considered ineffective. Recent developments in tumor genetics and a greater understanding of the role of the immune system in cancer have translated to better treatments. IMPLICATIONS FOR NURSING PRACTICE: Nurses play a key role in ensuring that patients with melanoma understand their diagnosis, treatment recommendations (including supportive care, palliative chemotherapy, immunotherapies), and participation in clinical trials.

Side effects in melanoma patients receiving adjuvant interferon alfa-2b therapy: a nurse's perspective.

PURPOSE: The aim of this review was to examine the toxicity profile of adjuvant interferon (IFN) alfa-2b in melanoma patients from a nursing perspective and to summarize practical information to guide the effective management of common IFN toxicities to improve patient comfort. METHODS: This is a narrative summary of both research and review articles identified by searching PubMed, National Cancer Institute, and American Cancer Society websites. It also assesses recognized guidelines on the management of adjuvant IFN toxicity relevant to nurses who are caring for patients receiving adjuvant IFN therapy. RESULTS: Adjuvant high-dose IFN alfa-2b (HDI) as compared with observation significantly prolongs relapse-free survival in patients with melanoma at high risk for recurrence after surgical resection; however, treatment compliance and patient quality of life can be compromised by its toxicity profile. HDI toxicities affect a number of organ systems and the majority of patients will experience some side effects. Common toxicities such as flu-like symptoms, fatigue, anorexia, neuropsychiatric symptoms, and laboratory abnormalities are discussed, along with both pharmacological and nonpharmacological management strategies. CONCLUSIONS: The considerable side effects of HDI can be managed using established strategies. Oncology nurses play a significant role in the management of patients with melanoma receiving adjuvant HDI, and their prompt recognition of side effects, together with an understanding of effective pharmacological and nonpharmacological interventions, will improve patient comfort; this has the potential to positively influence treatment adherence and completion of the recommended treatment course.

Managing immune-related adverse events to ipilimumab: a nurse's guide.

Ipilimumab is a U.S. Food and Drug Administration-approved novel T-cell potentiator that improves survival in metastatic melanoma. Ipilimumab blocks cytotoxic T-lymphocyte antigen-4, a negative regulator of the immune response, thus promoting T-cell activation and prolonging a patient's antitumor response. However, that action may produce a mechanism-related spectrum of immune-related adverse events (irAEs), which can become severe and life-threatening if left unrecognized and untreated. This article describes the clinical properties of ipilimumab, specifically in regard to its unique profile of irAEs. Guidelines to manage irAEs are reviewed with a particular emphasis on the contribution of nurses to patient care and education. The nurse's role in facilitating communication among the oncology team, primary practice team, patients, and caregivers is fundamental to early recognition and effective management of irAEs so that patients can continue on therapy. As a regular, ongoing presence in patient care, the oncology nurse is well placed to deliver information, assess patients' understanding of that information, and support them through their cancer experience. Checklists of irAE symptoms may be useful for patients and nurses alike. In addition, education on ipilimumab's mechanism of action and how it contributes to irAEs should form an integral part of the patient treatment plan.
