A proposed EGFR inhibitor dermatologic adverse event-specific grading scale from the MASCC skin toxicity study group

BackgroundAccurate grading of dermatologic adverse events (AE) due to epidermal growth factor receptor (EGFR) inhibitors (EGFRIs) is necessary for drug toxicity determinations, interagent comparisons, and supportive care trials. The most widely used severity grading scale, the National Cancer Institute’s Common Terminology Criteria for Adverse Events version 4.0 (NCI-CTCAE v4.0), was not designed specifically for this class of agents and may result in underreporting and poor grading of distinctive adverse events. We believe a class-specific grading scale is needed to help standardize assessment and improve reporting of EGFRI-associated dermatologic AEs.MethodsThe Multinational Association of Supportive Care in Cancer (MASCC) Skin Toxicity Study Group conducted an international multidisciplinary meeting that included 20 clinicians and researchers from academic centers and government agencies. Experts from different disciplines presented current information specific to EGFRI-induced dermatologic toxicities: grading scale development, pharmacovigilance safety reporting, health-related quality of life, patient reporting, and pharmacology. Group discussions, literature reviews, and professional expertise established the theoretical foundation for the proposed grading scale.ResultsA new grading system is proposed for the most common events associated with EGFRI-induced dermatologic AEs: papulopustular reaction or acneiform rash, nail changes, erythema, pruritus, xerosis, hair changes, telangiectasias, hyperpigmentation, mucositis, flushing, radiation dermatitis, hyposalivation, and taste changes. The proposed scale maintains consistency with the grading principles and language of the existing CTCAE version 4.0 and MedDRA terminology and includes relevant patient-reported health-related quality of life factors.ConclusionsA grading scale specific to EGFR inhibitor dermatologic AEs is presented for formal integration into future versions of CTCAE and for validation in clinical trial settings. The study group designed this scale to detect and report EGFRI-related toxicities with greater sensitivity, specificity, and range than the scales currently used. This scale should serve as a foundation for efforts to perform objective interdrug comparisons and assessments of supportive care treatment strategies more effectively than with current methods.

Durable Long-Term Responses in Patients with Myelodysplastic Syndromes Treated with Lenalidomide

Lenalidomide has proven efficacy and safety and has been shown to reduce transfusion requirements and reverse cytogenetic abnormalities in lower-risk myelodysplastic syndromes (MDS). However, long-term follow-up data have not yet been reported. Here, we describe 6 patients with International Prognostic Scoring System low- or intermediate-1-risk MDS who began lenalidomide therapy between April 2002 and June 2003 as part of the MDS-001 study and who have maintained long-term therapy. Five of these patients had an ongoing requirement for red blood cell transfusions despite previous treatment with recombinant erythropoietin. One patient began lenalidomide therapy because of progressive and symptomatic anemia. To date, all patients maintained long-term transfusion independence (over 4.5 years) while receiving oral lenalidomide therapy, including 5 patients who remain on therapy. Sustained erythroid response was reported despite persistence of the deletion 5q [del(5q)] abnormality in 3 of the 4 patients with del(5q) at study entry. Side effects were largely predictable and manageable. The favorable outcomes presented here show that lenalidomide can induce durable erythroid responses with sustained transfusion independence that can exceed 6 years in patients with lower-risk MDS.

Caregivers of multiple myeloma survivors.

Patients living with multiple myeloma (MM) face complex decisions throughout their journey relative to their diagnosis, options for treatment, and how their disease and treatment choices may affect them physically, emotionally, financially, and spiritually. Patients considering a hematopoietic stem cell transplantation face specific self-management challenges. The availability of a reliable caregiver is a prerequisite to transplantation eligibility. Currently, the majority of clinical management is episodic and provided in the outpatient setting. Therefore, the bulk of care for patients living with MM is provided by the patient together with his or her caregivers. Caregivers face similar challenges to those faced by the patient living with MM. They are required to take in complex information, perform often complicated or technical procedures such as line care or injections, assist the patient with activities of daily living, and attend the myriad of appointments required. Understanding the dynamics of the patient-caregiver relationship, the strengths and weaknesses unique to that relationship, common elements of caregiver stress or strain, and available tools and strategies to promote a sense of control and enhance self-management skills may improve the health-related quality of life for both the patient with MM and his or her caregiver.

Practical Management of Lenalidomide-Related Rash

Lenalidomide (LEN) is an immunomodulatory drug with US Food and Drug Administration approval for use in myelodysplastic syndromes (MDS), multiple myeloma (MM), and mantle cell lymphoma (MCL). The toxicity profile for LEN is similar across indications, with the most common adverse events reported in registration trials being hematologic in nature, and Grade ≥ 3 hematologic toxicities the most common reasons for treatment interruption or permanent LEN discontinuation. However, an analysis of the Celgene Global Drug Safety database showed that nonserious rash was the leading cause of permanent early discontinuation of LEN in patients with MDS treated in the postmarketing setting (similar data not available for patients with MM or MCL). In registration trials, rash was reported in up to a third of patients, but Grade ≥ 3 rash was uncommon and rash rarely led to LEN treatment interruption or permanent discontinuation. This suggests differences in management of LEN-related rash in clinical trials versus real-world use. Most LEN-related rash is mild to moderate in severity and might present as patchy, raised, macular skin lesions, sometimes with localized urticaria, which might be associated with pruritus. Mild to moderate rash might be treated with topical corticosteroids and/or oral antihistamines. Any grade LEN-related rash should be appropriately managed through awareness of symptoms, appropriate and prompt intervention, and maximizing patient self-reporting of early signs of rash using upfront educational initiatives. This guide to management of LEN-related rash reviews key clinical data from registration trials, and the incidence and physiology of LEN-related rash, grading of rash, and guidelines for patients and caregivers.

The relationship of TP53 R72P polymorphism to disease outcome and TP53 mutation in myelodysplastic syndromes

Nonsynonymous TP53 exon 4 single-nucleotide polymorphism (SNP), R72P, is linked to cancer and mutagen susceptibility. R72P associations with specific cancer risk, particularly hematological malignancies, have been conflicting. Myelodysplastic syndrome (MDS) with chromosome 5q deletion is characterized by erythroid hypoplasia arising from lineage-specific p53 accumulation resulting from ribosomal insufficiency. We hypothesized that apoptotically diminished R72P C-allele may influence predisposition to del(5q) MDS. Bone marrow and blood DNA was sequenced from 705 MDS cases (333 del(5q), 372 non-del(5q)) and 157 controls. Genotype distribution did not significantly differ between del(5q) cases (12.6% CC, 38.1% CG, 49.2% GG), non-del(5q) cases (9.7% CC, 44.6% CG, 45.7% GG) and controls (7.6% CC, 37.6% CG, 54.8% GG) (P=0.13). Allele frequency did not differ between non-del(5q) and del(5q) cases (P=0.91) but trended towards increased C-allele frequency comparing non-del(5q) (P=0.08) and del(5q) (P=0.10) cases with controls. Median lenalidomide response duration increased proportionate to C-allele dosage in del(5q) patients (2.2 (CC), 1.3 (CG) and 0.89 years (GG)). Furthermore, C-allele homozygosity in del(5q) was associated with prolonged overall and progression-free survival and non-terminal interstitial deletions that excluded 5q34, whereas G-allele homozygozity was associated with inferior outcome and terminal deletions involving 5q34 (P=0.05). These findings comprise the largest MDS R72P SNP analysis.

Autologous Hematopoietic Stem Cell Transplantation for Patients With Multiple Myeloma

Autologous hematopoietic stem cell transplantation (AHSCT) is approved for the treatment of select solid tumors, autoimmune disorders, and most hematologic malignancies. Multiple myeloma (MM) is the most common indication for AHSCT. Despite improvement in response and survival rates in the era of novel agents, AHSCT remains an important treatment option for patients with MM who are eligible. Clinical management of patients with MM requires a multidisciplinary approach that incorporates healthcare professionals in a number of clinical settings as well as caregivers and the patient. Patients about to undergo AHSCT are generally referred to tertiary care centers that specialize in ASCT. Pre- and post-transplantation treatments and long-term follow-up often are managed by a community-based referring oncologist in collaboration with the transplantation team. Oncology nurses play an integral role in the care of patients with MM in each clinical setting. This article aims to provide non-transplantation oncology nurses with guidelines for education, clinical management, and support of patients with MM undergoing AHSCT with a primary focus on the pre- and post-transplantation period.

Management of Transfusion-Related Iron Overload in Patients With Myelodysplastic Syndromes

Anemia is a common symptom for patients with myelodysplastic syndromes (MDS), a spectrum of hematopoietic malignancies characterized by ineffective hematopoiesis; 90% of these patients will become transfusion dependent (TD). Because of the closed nature of iron metabolism, the repeated input of packed red blood cells during transfusions inevitably leads to iron overload. Iron overload can cause iron-related toxicity as well as end-organ damage from iron deposition in tissues. Studies have shown that patients with MDS who are TD have shorter overall survival, shorter leukemia-free survival, and higher healthcare costs compared with patients who are not TD, suggesting that iron overload has a significant clinical and economic impact. Iron chelation therapy can bind and eliminate free iron from the body. Although studies in genetic anemias have shown improved clinical outcomes, clinical trials with patients with MDS are ongoing. Because iron chelation therapy can be toxic, the risks, benefits, and therapy-related costs must be weighed for each patient.

Identifying Professional Education Gaps and Barriers in Multiple Myeloma Patient Care: Findings of the Managing Myeloma Continuing Educational Initiative Advisory Committee

Advances in the past decade and a half have led to unprecedented improved outcomes for patients with multiple myeloma (MM), and this disease appears to be transitioning to one more characteristic of a chronic disease in large part due to rapid translation of clinical insights into practice at the community level. Although evidence-based guidelines and consensus recommendations remain an important resource for managing cancer patients, they do not fill the gap between the principles of disease management today and the translation of tailoring treatment for individual patient needs. Thus, there is a continuing need for concise, focused educational activities and resources that facilitate improved knowledge and understanding of appropriate, individualized therapeutic strategies for assessing and caring for patients with MM. The next several years will truly be a time of shifting paradigms in the treatment of MM in which new agents will be approved, response criteria will be updated, and new approaches to risk assessment and monitoring minimal residual disease will evolve and enter practice. New groundbreaking therapeutic approaches, such as immunotherapy, might result in significant changes in how MM is treated and managed over the entire life cycle of the disease. Even the definition of the disease might be further amended as insights grow regarding who should be treated and who might benefit more from observation. As such, oncology clinicians will have to carefully review and update their management approaches accordingly even as they begin to focus even more on the survivorship needs of their MM patients.

The Changing Landscape of Multiple Myeloma

Scientific advancements relative to diagnostic evaluation, risk-adapted treatment selection, and supportive care strategies for multiple myeloma (MM) have been developed in the past decade, which provides hope for patients living with MM. However, the disease remains incurable for the majority of patients, and continued clinical trials are necessary to refine existing therapeutic strategies and develop new approaches to treatment. Hematopoietic stem cell transplantation (HSCT), in particular autologous HSCT, remains an important component in the overall treatment paradigm for MM. This requires a well-organized team approach with ongoing communications and collaboration with community providers and other specialists. The majority of care for patients with MM is provided in the outpatient setting, relying on the active participation of both the patient and caregiver(s) for successful clinical outcomes. This supplement is prepared by members of the International Myeloma Foundation Nurse Leadership Board, which is dedicated to improving the care of patients with MM and their caregivers. The introduction serves to provide an overview of MM today and to summarize the articles included in this supplement.

Incidence and management of myelosuppression in patients with chronic- and accelerated-phase chronic myeloid leukemia treated with omacetaxine mepesuccinate.

Abstract Omacetaxine mepesuccinate (Synribo®) is an inhibitor of protein synthesis indicated for the treatment of patients with chronic- or accelerated-phase chronic myeloid leukemia (CML) with resistance and/or intolerance to two or more tyrosine kinase inhibitors. Myelosuppression is the most common and clinically significant toxicity experienced by patients treated with omacetaxine. Here, we further examine the patterns of hematologic toxicity observed in clinical trials and describe the approach to management as well as resolution of events. Omacetaxine-related myelosuppression typically occurs more frequently during induction cycles. In general, the myelosuppression observed with omacetaxine treatment is manageable and reversible, and long-term administration is feasible. Careful monitoring, dose delays and reduction in administration days, and appropriate supportive care are critical for successful management of hematologic toxicity. Concerns regarding myelosuppression, observed with many cancer treatments, should not prevent eligible patients from receiving omacetaxine, particularly CML patients with unsatisfactory responses to multiple lines of prior treatment.
