Cancer surveillance series [corrected]: brain and other central nervous system cancers: recent trends in incidence and mortality.

摘要: BACKGROUND During the 1980s, incidence of primary malignant brain and other central nervous system tumors (hereafter called cancer) was reported to be increasing among all age groups in United States, while mortality declining for persons younger than 65 years. We analyzed these data provide updates on trends cancer States examine patterns search their causes. METHODS Data incidence, overall according histology anatomic site, relative survival were obtained from Surveillance, Epidemiology, End Results (SEER) Program National Cancer Institute 1975 through 1995. Mortality Center Health Statistics. Medicare procedure claims Institute's SEER-Medicare database used imaging trends. Statistically significant changes identified, annual percent computed log linear models. RESULTS/CONCLUSIONS Rates stabilized during most recent period which SEER available, except group containing individuals 85 years or older. continued decline groups, steep increases seen past elderly slowed substantially. Patterns differed by site grade between older patients. last decade, use tomography scans relatively stable those 65-74 old but increased IMPLICATIONS Improvements diagnosis treatment patients likely explanations observed
