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

PurposeThe 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.MethodsThis 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.ResultsAdjuvant 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.ConclusionsThe 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.

Primer on Immuno-Oncology and Immune Response

Advances in the understanding of the immunogenicity of tumors have provided the basis for immuno-oncology, the development of immunotherapeutic agents that augment the patients antitumor immunity and disrupt the immune-regulatory circuits that allow tumors to evade the immune system. Two immunomodulatory agents recently have been introduced for the treatment of malignancy: sipuleucel-T and ipilimumab. Unlike cytotoxic chemotherapy, immunotherapies stimulate the patients immune system to mount or augment existing endogenous antitumor immune responses. Both agents have demonstrated significant improvements in long-term overall survival in patients. Like other immunotherapies, sipuleucel-T and ipilimumab also are characterized by adverse events that manifest as immune-related inflammatory conditions that typically are low grade. Management guidelines have been developed and emphasize early recognition of the signs and symptoms of immune-related adverse events and treatment with corticosteroids. Because these events can manifest even after the cessation of therapy, patients treated with immunotherapies should continue to be followed by their oncology team and other healthcare providers.

Clinicopathologic correlations of gallbladder cancer by ethnicity in New Mexico, 1980-2009.

160 Background: Gallbladder cancer (GBCA) is a rare malignancy; however, within the U.S. incidence varies geographically. GBCA has a higher occurrence in the American Indian (AI) population versus non-Hispanic whites (NHW) and Hispanics (H). The goal of the study is to determine if clinicopathologic features correlate with ethnicity. Methods: Incident GBCA diagnosed in New Mexico from 1980-2009 were identified from the population-based New Mexico Tumor Registry. Average age-adjusted incidence rates were calculated by direct method using the United States 2000 standard population. Chi-squared statistic was used to assess ethnicity differences in case distribution at diagnosis by sex, age, stage and grade. Cause-specific survival was calculated by the Kaplan-Meier method and assessed with log-rank statistic. Results: GBCA incidence rates in New Mexico are highest for AI (7.6 per 100,000–95% confidence interval (CI)=6.5-8.9), followed by H (2.8 per 100,000 – 95% CI=2.5-3.2) and NHW (1.0 per 100,000 – 95% CI=...
