Consensus guidelines have defined select less common skin cancers appropriate for Mohs micrographic surgery (MMS), as these tumors are characterized by asymmetric growth patterns that challenge conventional surgical extirpation of disease.
The authors aimed to define surgical patterns of care and to identify factors affecting treatment selection in the United States.
Retrospective cohort analysis of nonmetastatic nonmelanoma skin cancers deemed appropriate for MMS by American Academy of Dermatology/American College of Mohs Surgery/American Society for Dermatologic Surgery Association/American Society for Mohs Surgery appropriate use criteria from the National Cancer Data Base from 1998 to 2012.
Of the included 15,121 patients, 8% received MMS, 30% primary excision, 12% narrow re-excision, and 50% wide re-excision. Utilization of MMS was negatively influenced by community cancer programs, Northeast region, lower education, uninsured status, and administration of radiotherapy. High-risk face areas, lower comorbidity score, and microcystic adnexal carcinoma were associated with higher likelihood of receiving MMS. After adjusting for tumor size, tumor location, and histology, MMS remained an independent predictor of achieving negative surgical margins (odds ratio 3.15, 95% CI 2.27-4.36, and p < .0001).
There is considerable variation in surgical treatment patterns by both sociodemographic, treatment, and tumor characteristics. Despite low utilization, patients receiving MMS are more likely to achieve negative surgical margins and less likely to receive radiotherapy.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 08 April 2016.
All research outputs
#17,286,645
of 25,374,917 outputs
Outputs from Dermatologic Surgery
#1,933
of 3,066 outputs
Outputs of similar age
#191,103
of 311,862 outputs
Outputs of similar age from Dermatologic Surgery
#21
of 39 outputs
Altmetric has tracked 25,374,917 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,066 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.6. This one is in the 27th percentile – i.e., 27% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 311,862 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 30th percentile – i.e., 30% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 39 others from the same source and published within six weeks on either side of this one. This one is in the 28th percentile – i.e., 28% of its contemporaries scored the same or lower than it.
