A Dermatologist's Guide to Implementation of Gene Expression Profiling in the Management of Melanoma.

BACKGROUND. With the advent of effective therapeutics, melanoma mortality rates have decreased, yet incidence rates are continuing to rise, making accurate prognostication for risk of recurrence increasingly important. Gene expression profiling (GEP) is a clinically available, objective metric that can be used in conjunction with traditional clinicopathological staging to help physicians stratify risk in melanoma patients. There is a gap in guidance from the American Joint Committee on Cancer (AJCC) and the National Comprehensive Cancer Network (NCCN) regarding how to utilize GEP in melanoma care. OBJECTIVE. An expert panel of 31-GEP test users sought to provide clarification of use options and a rational clinical workflow to guide appropriate application of the 31- GEP test in everyday practice. METHODS. The authors participated in an in-depth review of the literature and panel discussion regarding current limitations of melanoma risk assessment and opportunities for improvement with GEP. The panel reviewed 1) validation and clinical impact data supporting the use of sentinel lymph node biopsy (SLNB), 2) existing primary data and meta-analyses for 31-GEP testing in melanoma risk assessment, 3) AJCC, NCCN, and Melanoma Prevention Working Group (MPWG) data and guidelines for GEP use in melanoma risk assessment, and 4) experiences, rationales, and scenarios in which 31-GEP testing may be helpful for risk assessment. RESULTS. The 31-GEP test is useful and actionable for patient care when applied in accordance with current NCCN guidelines. Stratification of patients into low (Class 1a), intermediate (Class 1b or 2a), or high (Class 2b) risk categories can inform multidisciplinary conference discussion and can assist with determining the intensity of imaging, surveillance, and follow-up care. Patient-specific features of the disease and individual circumstances should be considered in the decision to use 31-GEP testing. CONCLUSION. The authors suggest a clinical workflow that integrates 31-GEP testing under the umbrella of current national guidelines. Application of the test in appropriate patient populations can improve risk assessment and inform clinical decision-making.

Music for patients with hematological malignancies undergoing bone marrow biopsy: a randomized controlled study of anxiety, perceived pain, and patient satisfaction.

OBJECTIVE: To examine the impact of random assignment to music versus usual care on anxiety, perceived pain level and patient satisfaction in patients undergoing bone marrow biopsies. METHOD: Patients were randomized to music or usual care after completing a baseline questionnaire. All patients completed a post-procedure questionnaire. RESULTS: Study participants (N=59) had a mean age of 50.9 years (SD = 13.9; range 22-78). Post-procedure state anxiety (STAI) and pain rating (VAS) were not significantly different between groups (STAI p=0.766; VAS p=0.771). However, patient satisfaction with music was high; 66% of these patients said they very much preferred to listen to music at a future biopsy. CONCLUSIONS: While there were no significant group differences for the music intervention compared to standard of care for anxiety or perceived pain, additional feedback indicated that patients found the music intervention beneficial and requested use of music during future procedures.
