UNASSIGNED: The incidence of @entity957 ( @entity6461 ) is rapidly increasing in white populations, causing high morbidity and health-care costs. Few studies, however, have described the trends for @entity6461 , as population-based data with a long follow-up are limited. In Norway we have this opportunity and we aimed to describe @entity6461 incidence, mortality and survival rates, according to sex, age, stage, primary anatomical location, and geographical region, for the period 1963-2011, for estimation of future health-care needs. Data were retrieved from the Cancer Registry of Norway. Age-adjusted @entity6461 incidence and mortality rates and 5-year relative survival (in percent) were calculated for 5-year calendar periods. A joinpoint regression model identified the annual percentage change (APC) in rates over the 50-year period. The age-adjusted incidence rate increased ninefold in females and sixfold in males from 1963 to 2011, with @entity11527 of 5.6% (95% confidence interval, CI 4.5, 7.3) and 3.3% (95% CI 1.3, 5.3) in females and males, respectively. @entity6461 incidence rose in all age groups, anatomical locations (except ears in females), and geographical regions, though restricted to localized @entity5 . Most striking increase was seen in the age group 70-79, in face and head locations and among residents in southern Norway. @entity6461 mortality and survival rates remained relatively stable. Our findings underline an increasing need for @entity6461 treatment in Norway, especially considering the aging population. The findings also call for the creation of particular guidelines for primary prevention of @entity6461 .
