Statin refills after diagnosis of poor-prognosis cancer persisted in 58% of secondary prevention and 62% of primary prevention patients, with no significant differences in timing of discontinuation.

Does statin prescribing indication (secondary vs primary prevention) affect the continuation of statins in patients with poor-prognosis cancer?
In patients with poor-prognosis cancer, statin refills persist at similar rates regardless of whether they were prescribed for primary or secondary cardiovascular prevention, highlighting a potential opportunity to reevaluate medication burden at the end of life.
Absolute Event Rate: 58% vs 62%
BACKGROUND: There are no evidence-based recommendations for statin continuation or discontinuation near the end of life. However, some expert opinion recommends continuing statins prescribed for secondary versus primary prevention of cardiovascular disease. OBJECTIVES: Our aim was to explore statin prescribing patterns in a longitudinal cohort of individuals with life-limiting illness, and to evaluate differences in these patterns based on secondary versus primary prevention of cardiovascular disease. DESIGN AND SETTING: This study was a retrospective cohort analysis of 539 persons in an integrated, not-for-profit health maintenance organization (HMO) setting who were receiving statins at diagnosis of a cancer with 0% to 25% predicted 5-year survival. Of the cohort patients, 343 were taking statins for secondary prevention and 196 for primary prevention of cardiovascular disease. Measurements included number and timing of statin refills between diagnosis and date of death, disenrollment, or the end of the observation period. RESULTS: Four hundred and ninety-six cohort members died within the observation period. Fifty-eight percent of the secondary prevention and 62% of the primary prevention group had at least one statin refill after diagnosis. There were no significant differences between groups for number of days between diagnosis and last refill, or between last refill and death. Two deaths were attributable to cardiovascular causes in each group. CONCLUSIONS: Our retrospective cohort analysis of persons with incident poor-prognosis cancer describes diminished, but persistent statin refills after diagnosis. Neither timing of statin discontinuation nor cardiovascular mortality differed by prescribing indication. There may be an opportunity to reevaluate medication burden in persons taking statins for primary prevention, and it is unclear whether continuing statins prescribed for secondary prevention affects cardiovascular outcomes.
Bayliss et al. (Thu,)는 예상 5년 생존율 0%에서 25% 사이의 암 환자를 대상으로 코호트 연구(n=539)를 수행했습니다. 스타틴 지속(2차 예방) 대 스타틴 지속(1차 예방)은 진단 후 최소 하나의 스타틴 리필을 평가했습니다. 예후가 불량한 암 진단 이후 스타틴 리필은 2차 예방 환자의 58%와 1차 예방 환자의 62%에서 지속되었으며, 중단 시기에 유의한 차이는 없었습니다.
