Epidemiologic investigation of nonmelanoma skin cancer mortality: the Rhode Island Follow-Back Study.
The Rhode Island Follow-Back Study was initiated to elucidate the magnitude and characteristics of nonmelanoma skin cancer mortality. All deaths reported among Rhode Island residents during 1979 through 1987 and attributed to nonmelanoma skin cancer were investigated and medical records sought. Most were misclassified, primarily due to squamous cell carcinoma of mucosal surfaces in the head and neck. In Rhode Island and nationally, this source of misclassification is increasingly frequent. Appropriate adjustment of national statistics for misclassification reveals a consistent decline in nonmelanoma skin cancer mortality rates from 1969 through 1988, although the actual numbers of deaths are increasing due to growth and aging of the population. Examination of the records of those Rhode Island residents who did die from nonmelanoma skin cancer demonstrated that most had squamous cell carcinoma, and many of those arose from the ear. These analyses suggest that particular emphasis should be placed on the ear in public health campaigns geared toward the prevention and early detection of nonmelanoma skin cancer.
