Coffee, Citrus, and Alcohol: A Review of What We Drink and How it May Affect our Risk for Skin Cancer.

Climate change and environmental health are closely linked with agriculture and food supply. The environment influences accessibility, quality, and variety of foods and drinks that are available for consumption, which in turn influences population health. A growing area of research is the role of dietary intake of nutrients and how they may influence risk for skin cancer. In recent years, our group has studied dietary nutrients, particularly those found in commonly consumed beverages, such as those containing caffeine, citrus products, and alcohol, in large prospective cohorts to evaluate how their intake may influence risk for skin cancer. Our data suggest that intake of citrus juices, when consumed around once per day or more, or around 5 to 6 times per week, may be associated with increased risk for both keratinocyte carcinomas (KC) and malignant melanoma (MM). With regards to alcohol consumption, we have found that intake of white wine may be associated with increased risk for both KC and MM, while beer and red wine have not shown such associations. Lastly, our work suggests caffeinated beverages, including coffee, tea, and cola, may be associated with decreased risk for basal cell carcinoma (BCC) and MM. While the associations between food intake and skin cancer development are complex, and remain to be further analyzed in future studies, we hope that our summary may help guide individuals to small changes they may make towards potentially reducing their risk for certain skin cancers.

Understanding melanoma in situ: Lentigo maligna surgical treatment terminology and guideline adherence, a targeted review.

BACKGROUND: Malignant melanoma in-situ, lentigo maligna (MMIS-LM) can be successfully treated with several different surgical techniques; however, the literature is inconsistent in defining them. OBJECTIVE: To comprehensively define and describe the national guideline recommended surgical techniques used to treat MMIS-LM to help clarify and standardize this terminology to ensure compliance with the guidelines. METHODS: A targeted literature review was performed from 1990 to 2022 focusing on articles that discussed the national guideline recommended surgical techniques of wide local excision, Mohs micrographic surgery (MMS), modified Mohs surgery, and staged excision/Slow-Mohs for MMIS-LM, as well as the related methods of tissue processing. National Comprehensive Cancer Network and American Academy of Dermatology guidelines were reviewed to identify how the techniques need to be employed to be compliant with guideline recommendations. RESULTS: We describe the various surgical and tissue processing techniques and discuss advantages and disadvantages of each. LIMITATIONS: This paper was styled as a narrative review defining and clarifying terminology and technique and does not investigate these topics more broadly. CONCLUSION: Understanding the methodology and terminology for these surgical procedures and tissue processing methods is critical so that both general dermatologists and surgeons can employ these techniques effectively for optimal patient care.
