Survival rates with XXXX in the United States: 1973-1997.

@entity1 @entity2184 @entity320
PURPOSE: To determine variations in 5-year relative survival rates with primary @entity2184 in the United States over a 25-year period from 1973 to 1997. DESIGN: Systematic review of existing databases. @entity1 : Two thousand four hundred ninety-three @entity1 with primary @entity2184 , International Classification of Oncology [ICDO-2] codes C69.3 [ @entity320 ] and C69.4 [ciliary body and iris]) derived from Surveillance, Epidemiology, and End Results (SEER) program database in the United States from 1973 to 1997. METHODS: The @entity1 were stratified according to the treatment (surgery or radiotherapy). The relative 5-year survival was calculated for 2054 @entity1 diagnosed between 1973 and 1993 by the life table method using US life expectancy tables. MAIN OUTCOME MEASURES: The relative 5-year survival rate. RESULTS: Surgical treatment was performed in 1476 (72%) cases, and radiotherapy was given in 300 (15%) cases. The proportion of cases treated by radiotherapy increased progressively from 2% to 28% in 20 years. Relative 5-year survival rates ranged from 77% to 84% without a statistically significant variation. CONCLUSIONS: Advances made in the local methods of treatment of primary @entity2184 have not led to an improvement in survival. Systemic approaches to management of @entity2184 are warranted.
