@entity1 @entity22550 @entity3821
Data from numerous studies show that lumpectomy (breast-conserving therapy) plus radiation therapy provides survival equivalent to that following mastectomy (either modified radical or radical mastectomy) for @entity1 with @entity3821 ( @entity3821 ). According to the data from the National Cancer Data Base and the Surveillance Epidemiology End Results (SEER) Program, use of lumpectomy among female @entity3821 @entity1 has increased dramatically over the last decade. This study examined population-based trends in treatment for @entity3821 among Louisiana @entity1 and compared the trends with the SEER data. Our data revealed that the percentage of the @entity3821 @entity1 who received a lumpectomy increased from 34.3% in 1988-1991 to 53.7% in 1996-1999 in Louisiana (p<0.05) while @entity3821 @entity1 who received a modified radical mastectomy decreased from 51.7% to 26.1% (p<0.05). Increasing use of lumpectomy was seen across all races, age groups, @entity22550 , and poverty-level areas. Utilization of lumpectomy was about the same for white and African-American @entity1 but varied by age group, @entity22550 , and poverty level. Female @entity3821 @entity1 residing in rural areas or high poverty level areas were less likely to receive a lumpectomy than those residing in urban or affluent areas. Among the @entity1 who had a lumpectomy, 34.4% received post-lumpectomy radiotherapy in the first study period (1988-1991) and 49.7% in the last study period (1996-1999). In Louisiana, utilization of post-lumpectomy radiotherapy decreased with advancing age. Despite the increase in use of lumpectomy, its utilization remained approximately 10% lower than in the SEER areas throughout the study period. A similar deficit was observed for post-lumpectomy radiation therapy.
