Hypothesis
Patients with melanoma of the head or neck would be at particularly high risk of nonmelanoma skin cancer and specifically SCCs.
Conclusion
Patients with melanoma have a significantly higher risk of developing nonmelanoma skin cancers compared to those with other solid tumors.
Supporting Evidence
- Melanoma patients were almost five-fold more likely to develop keratinocytic cancers compared to solid tumor controls.
- 68% of melanoma cases with nonmelanoma skin cancers had basal cell carcinomas.
- The overall prevalence of nonmelanoma skin cancers was 7% among melanoma cases.
Takeaway
People with melanoma are much more likely to get other skin cancers, especially depending on where their melanoma is located.
Methodology
Registry-based case–control study comparing melanoma patients with solid tumor controls for the prevalence of nonmelanoma skin cancers.
Potential Biases
Increased surveillance of melanoma patients may lead to higher diagnosis rates of nonmelanoma skin cancers.
Limitations
Nearly half of melanoma notifications were excluded due to missing histological information.
Participant Demographics
Mean age of melanoma diagnosis was 54 years, with 50% male participants.
