RESUMO
OBJECTIVE: The authors aimed to investigate life expectancy after adult cardiac surgery. SETTING: Nationwide study including University and non-University hospitals. PARTICIPANTS: Consecutive adult patients who underwent heart valve and coronary artery surgery from a nationwide administrative registry. INTERVENTIONS: Surgical procedures on the heart valves and coronary arteries. METHODS: The authors estimated the 10-year relative survival of adult patients who underwent surgery for heart valve diseases and coronary artery disease taken from a nationwide administrative registry. MEASUREMENTS AND RESULTS: Overall, data on 415,472 patients were available for this study. Among them, 394,445 (94.9%) survived 90 days after surgery, and their 10-year survival was 58.0% (95% CI 57.8-58.3); the expected survival was 70.1%, and the relative survival was 0.83 (95% CI 0.82-0.83). Patients who underwent surgical repair of the mitral valve and aortic valve had relative survival of 0.96 and 0.92, respectively. Isolated coronary artery bypass grafting had a relative survival of 0.88. Surgical replacement of the heart valves had a relative survival below 0.80. Poor results with relative survival <0.70 were observed after complex cardiac surgery. Relative survival was <0.60 in patients who underwent double- or triple-valve surgery combined with coronary artery surgery. The authors observed markedly lower relative survival among women (0.77, 95% CI 0.77-0.78) compared with men (0.86, 95% CI 0.85-0.86) at 10 years. Such a difference was observed after almost all different procedures. CONCLUSIONS: The present findings provided a picture of the real expectation in terms of the late survival of patients after having undergone adult cardiac surgery. This information should be communicated to patients and their relatives before surgery, and it may be relevant in the decision-making process and in planning tertiary prevention.
RESUMO
The frequency of patients who switch to a second-line therapy from a frontline second-generation (2gen) tyrosine kinase inhibitor (TKI) such as dasatinib and nilotinib, is still substantially unknown. We retrospectively investigated a large series of chronic phase chronic myeloid leukemia (CP-CML) patients initially treated with 2gen TKIs monitored through the Italian Medicines Agency (AIFA Agenzia Italiana del farmaco) registries. Overall, 2420 patients were analyzed over a period of 6 years. One hundred and fifty-seven patients (16.3%) treated with dasatinib and 164 treated with nilotinib (11.3%) have switched to another drug, with an overall frequency of 13.2%. In the dasatinib cohort, 39.4% of patients changed treatment for failure and 36.3% for intolerance as compared to 45.7% and 27.4% respectively in the nilotinib cohort. Overall, the median time to switch due to resistance was 293 days, whereas it was 317 days in case of intolerance. Resistance was observed mainly in younger male patients with high-risk features, while intolerance was not related to any baseline parameter. After resistance/intolerance to nilotinib, the majority of patients switched to dasatinib (53.8%) whereas in case of frontline dasatinib to ponatinib (43.2%). To the best of our knowledge these data provide the first report on the frequency of discontinuation of frontline 2gen TKIs and on the main causes and pattern of choice to a second-line therapy in the real-life setting.
