RESUMO

BACKGROUND: Actinic keratoses (AKs) are very common and it is therefore important to consider how morbidity of this disease impacts quality of life (QoL). Previous longitudinal studies of skin-related QoL in a high-risk population found no effect of increased AK counts on subsequent skin-related QoL, even though higher AK counts were associated with worse skin-related QoL cross-sectionally. OBJECTIVES: To determine if development of new actinic keratoses (AKs) are associated with worse skin-related QoL in those at high risk of keratinocyte carcinoma (KC). MATERIALS AND METHODS: A prospective analysis was performed using data from the Veterans Affairs Keratinocyte Carcinoma Chemoprevention Trial, a randomized, double-blinded, placebo-controlled trial of topical 5-fluorouracil for chemoprevention of KC. We report correlates of skin-related quality of life, a secondary outcome of the trial. Demographic and health-related information were self-reported and AK multiplicity on the face/ears were noted on semi-annual skin exams. Skindex-29 and Skin Cancer Index instruments were used to assess skin-related QoL yearly. RESULTS: Participants with increased AK counts had worse skin-related QoL compared to those with unchanged or decreased counts, particularly in Year 1. CONCLUSION: Our findings of impaired skin-related QoL associated with AKs underscore the importance of appropriate management to reduce the burden of disease.

RESUMO

Importance: Keratinocyte carcinoma (ie, cutaneous basal and squamous cell carcinoma) is the most common cancer in the United States. Objective: To determine whether topical fluorouracil could prevent surgically treated keratinocyte carcinoma. Design, Setting, and Participants: The Veterans Affairs Keratinocyte Carcinoma Chemoprevention Trial was a randomized, double-blind, placebo-controlled trial of topical fluorouracil for chemoprevention of keratinocyte carcinoma. Participants were recruited from May 2009 to September 2011 from 12 Veterans Affairs medical centers and followed until June 30, 2013. Participants were veterans (n = 932) with a history of at least 2 keratinocyte carcinomas in the past 5 years; almost all were white males and the median age was 70 years. Interventions: Application of fluorouracil, 5%, (n = 468) or vehicle control cream (n = 464) to the face and ears twice daily for 2 to 4 weeks upon randomization. Main Outcomes and Measures: Surgically treated keratinocyte, basal cell, and squamous cell carcinoma risk on the face and ears in the first year after enrollment; and time to first surgically treated keratinocyte, basal cell, and squamous cell carcinoma. The a priori hypothesis was that fluorouracil would be effective in preventing these cancers. Results: Of 932 participants (916 men [98%]; 926 white [99%]; median age, 70 years), 299 developed a basal cell carcinoma end point (95 in year 1) and 108 developed a squamous cell carcinoma end point (25 in year 1) over 4 years (median follow-up, 2.8 years). Over the entire study, there was no difference between treatment groups in time to first keratinocyte, basal cell, or squamous cell carcinoma. During the first year, however, 5 participants (1%) in the fluorouracil group developed a squamous cell carcinoma vs 20 (4%) in the control group, a 75% (95% CI, 35%-91%) risk reduction (P = .002). The 11% reduction in basal cell carcinoma risk during year 1 (45 [10%] in the fluorouracil group vs 50 [11%] in the control group) was not statistically significant (95% CI, 39% reduction to 31% increase), nor was there a significant effect on keratinocyte carcinoma risk. However, a reduction in keratinocyte carcinomas treated with Mohs surgery was observed. Conclusions and Relevance: A conventional course of fluorouracil to the face and ears substantially reduces surgery for squamous cell carcinoma for 1 year without significantly affecting the corresponding risk for basal cell carcinoma.

RESUMO

BACKGROUND: Population-based screening for the early detection of melanoma holds great promise for reducing melanoma mortality, but evidence is needed to determine whether benefits outweigh risks. Skin surgeries and dermatology visits after screening were assessed to indicate potential physical, psychological, and financial consequences. METHODS: Targeted primary care providers (PCPs) at the University of Pittsburgh Medical Center were trained to detect early melanoma using the INFORMED (INternet course FOR Melanoma Early Detection) program. The authors analyzed aggregated administrative data describing 3 groups of patients aged ≥35 years who had received an annual physical examination by PCPs: group A1 included patients of PCPs from the group with the highest percentage of INFORMED-trained providers, group A2 included patients of PCPs from the group with a lower percentage of INFORMED-trained providers, and group B included patients of PCPs without INFORMED training. RESULTS: INFORMED-trained PCPs screened 1572 of 16,472 patients in groups A1 or A2 and none of the 56,261 patients in group B. In group A1, there was a 79% increase (95% confidence interval, 15%-138%) in melanoma diagnoses noted; no increase was observed for the other groups, and no substantial increase in skin surgeries or dermatology visits occurred in any group. CONCLUSIONS: A large-scale melanoma screening using the INFORMED program was conducted in Pennsylvania. To the best of the authors' knowledge, the current study is the first analysis of downstream results and the findings indicate increased melanoma diagnoses but little impact on skin surgeries or dermatology visits. This result provides some reassurance that such efforts can be conducted without major adverse consequences, at least as measured by these parameters, and therefore should be considered for more widespread use.
