Malignant melanoma is the fifth most common of all tumours. Melanoma is caused by harmful ultraviolet radiation causing damage to the skin. Increased travels to the sun and tanning bed use are probable factors for the increase of the disease. In 2018, there were more than 4700 invasive melanomas diagnosed in Sweden. The age-adjusted incidence was 47/100,000, slightly more men than women. The total incidence increase per year was more than 5 percent the last 10 years.
The last 3 years more than 500 individuals have died due to melanoma, half of which were older than seventy-five.
Early diagnosis with a high proportion of thin melanomas provides a relative five-year survival rate of 93 percent for women and 86 percent for men. Informing the population about the disease, signs of diagnosis, where to turn, the use of dermatoscope as well as sun protection and banning tanning bed habits should hopefully be able to halt the increase rate of the disease, not yet seen in Sweden.
Purpose and objectives:
All individuals diagnosed with invasive melanoma are registered via the INCA portal. In situ melanoma is not registered individually but later included from the Swedish Cancer Registry.
The inclusion rate is above 95 percent most years. At present, there are about 67,000 primary invasive melanoma tumours registered since the start of SweMR.
4 700 new primary CMM.
The coverage rate is the number of cases of melanoma in the registry/number of cases in the quality registry. In 2011, the coverage rate was estimated at 95 percent.
Validation is only done in conjunction with registration by the monitor at the Regional Cancer Center before data is entered on the national database for SweMR. The registration is online with barriers for incongruous values.
Note: Variable lists are updated on a regular basis by the steering committee of SweMR. For the latest version, please contact the registry.
