Melanoma and melanoma in-situ diagnosis after excision of atypical intraepidermal melanocytic proliferation: A retrospective cross-sectional analysis.

BACKGROUND: There is little evidence to guide surgical management of biopsies yielding the histologic descriptor atypical intraepidermal melanocytic proliferation (AIMP). OBJECTIVE: Determine frequency of and factors associated with melanoma and melanoma in-situ (MIS) diagnoses after excision of AIMP and evaluate margins used to completely excise AIMP. METHODS: Retrospective, cross-sectional study of 1127 biopsies reported as AIMP and subsequently excised within one academic institution. RESULTS: Melanoma (in situ, stage 1A) was diagnosed after excision in 8.2% (92/1127) of AIMP samples. Characteristics associated with melanoma/MIS diagnosis included age 60-79 years (odds ratio [OR] 8.1, 95% confidence interval [CI] 2.5-26.2), age ≥80 years (OR 7.2, 95% CI 1.7-31.5), head/neck location (OR 4.9, 95% CI 3.1-7.7), clinical lesion partially biopsied (OR 11.0, 95% CI 6.7-18.1), and lesion extending to deep biopsy margin (OR 15.1, 95% CI 1.7-136.0). Average ± standard deviation surgical margin used to excise AIMP lesions was 4.5 ± 1.8 mm. LIMITATIONS: Single-site, retrospective, observational study; interobserver variability across dermatopathologists. CONCLUSION: Dermatologists and pathologists can endeavor to avoid ambiguous melanocytic designations whenever possible through excisional biopsy technique, interdisciplinary communication, and ancillary studies. In the event of AIMP biopsy, physicians should consider the term a histologic description rather than a diagnosis, and, during surgical planning, use clinicopathologic correlation while bearing in mind factors that might predict true melanoma/MIS.

Association of Quality of Life With Surgical Excision of Early-Stage Melanoma of the Head and Neck.

Importance: Surgical excision is the standard-of-care treatment for Tis and T1a melanomas of the head and neck. Currently, however, the association of diagnosis and surgical treatment of these typically slowly progressive and nonfatal melanomas with a patient's health-related quality of life (HRQoL) is unknown. Objective: To characterize and assess HRQoL in patients with Tis and T1a head and neck melanoma, evaluate changes in HRQoL over the surgical treatment course, and identify patient characteristics associated with lower HRQoL. Design, Setting, and Participants: This longitudinal, prospective cohort study involved patients with Tis or T1a melanoma of the head and neck who underwent staged excision at a single tertiary care center (Memorial Sloan Kettering Cancer Center, New York, New York) and were recruited from June 1, 2016, to February 28, 2017. Patients were followed up for 1 year after their surgical procedure. Participants were asked to complete 2 patient-reported outcome measure questionnaires, Skindex-16 and Skin Cancer Index (SCI), at 4 time points: baseline, perioperative (1 to 2 weeks after surgery), and 6-month and 1-year follow-up. Main Outcomes and Measures: Scores on the Skindex-16 and SCI questionnaires. Results: In total, 56 patients were included in the study, among whom 24 (43%) were female and 32 (57%) were male, with a mean (range) age of 67.2 (32-88) years; all patients self-identified as white. Forty-one (73%) questionnaires at perioperative, 49 (88%) at 6-month postoperative, and 41 (73%) at 1-year postoperative time points were completed. At baseline, female patients and those younger than 65 years had statistically significantly worse HRQoL on the Skindex-16 questionnaire (mean score, 14.2 [95% CI, 9.1-21.9] and 16.1 [95% CI, 9.8-26.4]) and on the SCI questionnaire (mean score, 57.2 [95% CI, 48.3-67.6] and 53.2 [95% CI, 44.1-64.3]) compared with males (mean Skindex-16 score, 7.0 [95% CI, 4.8-10.3]; mean SCI score, 73.5 [95% CI, 66.0-81.7]) and those aged 65 years or older (mean Skindex-16 score 7.1 [95% CI, 5.0-10.0]; mean SCI score, 74.3 [95% CI, 67.7-81.6]). Questions that demonstrated the worst scores at baseline were worry about skin condition (Skindex-16) and worry about future skin cancers (SCI). The emotions subscale scores on the Skindex-16 questionnaire showed the greatest improvement from baseline to 1-year follow-up levels (26.6 vs 15.3; P < .001) and so did the appearance subscale scores on the SCI questionnaire (64.0 vs 84.6; P < .001). The score difference in HRQoL by sex diminished over time, whereas the score difference by age persisted through the first year. Conclusions and Relevance: Improvement in HRQoL at the 6-month and 1-year follow-up was associated with surgical excision in patients with early-stage head and neck melanoma, and younger and female patients experienced worse HRQoL. These results may be used in tailoring counseling for this patient population.

Effect of laser therapy on quality of life in patients with radiation-induced breast telangiectasias.

OBJECTIVE: To evaluate the effects of laser monotherapy on quality of life in breast cancer patients with chronic radiation dermatitis. STUDY DESIGN: A prospective, IRB-approved study was conducted at Memorial Sloan Kettering Cancer Center. Breast cancer patients with chronic radiation dermatitis completed health-related quality of life (HR-QOL) questionnaires before and after laser monotherapy for radiation-induced breast telangiectasias (RIBT). METHODS: After informed consent, all patients were issued the Skindex-16 and Breast-Q Adverse Effects of Radiation HR-QOL questionnaires prior to receiving laser treatment. Patients were treated with a 595 nm pulsed dye laser at 4- to 6-week intervals, with percent telangiectasia clearance and adverse events recorded at each visit. Post-treatment HR-QOL questionnaires were collected after clinician-assessed telangiectasia clearance of >50%. Median HR-QOL scores before and after therapy were reported for individual HR-QOL domains (Skindex-16) and HR-QOL totals (Skindex-16 and Breast-Q Adverse Effects of Radiation). Before- and after-differences were calculated using the Wilcoxon Signed-Rank Test. RESULTS: Twenty-two female patients (average age 56 years) enrolled in this study. A majority (13/22, 59%) exhibited telangiectasias across the décolletage and axilla in addition to the breast. Sixteen patients reached the 50% RIBT clearance threshold during the study period, and 11 of these patients (69%) completed follow-up HR-QOL questionnaires. Patients showed statistically significant improvements in emotional and functional Skindex-16 HR-QOL domains and in overall Skindex-16 HR-QOL score. Breast-Q scores also improved significantly, illustrating a decrease in specific physical and cosmetic concerns common to radiated breast skin. Common adverse events were transient post-treatment pain and redness. CONCLUSION: Breast cancer patients with RIBT presented with substantial deficits in several HR-QOL arenas. Laser monotherapy effectively treated the appearance of radiation dermatitis in these patients and also significantly improved HR-QOL. Lasers Surg.

Rising rates of vaccine exemptions: problems with current policy and more promising remedies.

Parents of school-age children are increasingly claiming nonmedical exemptions to refuse vaccinations required for school entry. The resultant unvaccinated pockets in many areas of the country have been linked with outbreaks of vaccine-preventable diseases. Many states are now focused on reducing rates of nonmedical exemptions by making exemption processes more restrictive or burdensome for the exemptor. These strategies, however, pose ethical problems and may ultimately be inadequate. A shift to strategies that raise the financial liabilities of exemptors may lead to better success and prove ethically more sound. Potential areas of reform include tax law, health insurance, and private school funding programs. We advocate an approach that combines this type of incentive with more effective vaccination education.

Exempting schoolchildren from immunizations: states with few barriers had highest rates of nonmedical exemptions.

Rates of nonmedical exemptions from school immunizations are increasing and have been associated with resurfacing clusters of vaccine-preventable diseases, such as measles. Historically, state-level school immunization policies successfully suppressed such diseases. We examined state immunization exemption regulations across the United States. We assessed procedures for exempting schoolchildren and whether exemption rates were associated with the complexity of the procedures. We also analyzed legal definitions of religious objections and state legislatures' recent modifications to exemption policies. We found that states with simpler immunization exemption procedures had nonmedical exemption rates that were more than twice as high as those in states with more-complex procedures. We also found that the stringency of legal definitions of religious exemptions was not associated with exemption procedure complexity. Finally, we found that although there were more attempts by state legislatures to broaden exemptions than to tighten them in 2011-13, only bills tightening exemptions passed. Policy makers seeking to control exemption rates to achieve public health goals should consider tightening nonmedical exemption procedures and should add vaccine education components to the procedures by either mandating or encouraging yearly educational sessions in schools for parents reluctant to have their children vaccinated.
