Multicenter, Prospective, Case-control Study of Exposome in Melanoma.

Area of Science:

• Dermatology
• Environmental Health
• Epidemiology

Background:

• Ultraviolet (UV) radiation is a primary cause of skin cancer.
• Environmental exposures, diet, and lifestyle significantly contribute to skin cancer development.

Purpose of the Study:

• To investigate the association between melanoma and exposome factors in the Spanish population.
• To identify specific environmental and lifestyle factors contributing to melanoma risk.

Main Methods:

• Prospective multicenter case-control study design.
• Inclusion of 73 melanoma patients (cases) and 126 controls without a history of skin cancer.
• Data collection on sun exposure, sunburns, medication use, and protective behaviors.

Main Results:

• Melanoma patients reported higher sun exposure and more sunburns compared to controls.
• Increased outdoor work, history of skin cancer, and use of specific drugs (acetylsalicylic acid, antidepressants, ACE inhibitors) were associated with melanoma.
• Controls utilized more protective measures like shade and clothing, and had used higher sun protection factor (SPF) historically.

Conclusions:

• Melanoma risk is associated with cumulative sun exposure, certain drug intakes, and dietary factors.
• Targeted prevention strategies are needed for high-risk groups, including outdoor workers.
• Promoting sun-safe behaviors and healthy lifestyles from childhood is essential for mitigating melanoma risk.
