Melanoma and environmental health
Melanoma is a serious form of skin cancer, and, together with Australia, New Zealand has the highest rates in the world . In 2021, there were 2,859 registrations of melanoma in New Zealand. Melanoma was the third most commonly registered cancer in 2019 for males (behind prostate cancer and colon cancer) and for females (behind breast and colon cancer).
Overexposure to UV radiation from the sun is the main environmental risk factor for melanoma. It has been estimated that more than 90% of all melanoma cases in New Zealand can be attributed to UV radiation exposure .
There were 2,859 melanoma registrations in 2021
In 2021, there were 2,859 melanoma registrations in New Zealand. The melanoma registration rate has always been higher for males than females over the past 20 years.
296 people died from melanoma in 2018
In 2018, 296 people died from melanoma in New Zealand. This is a 22% decline since 2015 (378 deaths). Age-standardised mortality rates also decreased a statistically significant amount between 2015 (3.3 per 100,000) and 2018 (4.9 per 100,000).
The decrease in melanoma deaths from 2015 to 2018 may be linked to the availability of two new treatments for advanced melanoma - Opdivo and Keytruda. These treatments began receiving public funding by Pharmac in July 2016 and September 2016 respectively. The decrease in melanoma deaths is likely due to these new treatments, as (i) it is in line with what would be expected from the addition of these PD-L1 treatments, based on clinical studies, and (ii) there are no other major factors that explain this large decrease .
