Effect of sarcopenia and frailty on outcomes among patients with brain metastases.

PURPOSE: Sarcopenia and frailty have been associated with increased mortality and duration of hospitalization in cancer. However, data investigating these effects in patients with brain metastases remain limited. This study aimed to investigate the effects of sarcopenia and frailty on clinical outcomes in patients with surgically treated brain metastases. METHODS: Patients who underwent surgical resection of brain metastases from 2011 to 2019 were included. Psoas cross-sectional area and temporalis thickness were measured by two independent radiologists (Cronbach's alpha > 0.98). Frailty was assessed using the Clinical Frailty Scale (CFS) pre-operatively and post-operatively. Overall mortality, recurrence, and duration of hospitalization were collected. Cox regression was performed for mortality and recurrence, and multiple linear regression for duration of hospitalization. RESULTS: 145 patients were included, with median age 60.0 years and 52.4% female. Psoas cross-sectional area was an independent risk factor for overall mortality (HR = 2.68, 95% CI 1.64-4.38, p < 0.001) and recurrence (HR = 2.31, 95% CI 1.14-4.65, p = 0.020), while post-operative CFS was an independent risk factor for overall mortality (HR = 1.88, 95% CI 1.14-3.09, p = 0.013). Post-operative CFS (ß = 15.69, 95% CI 7.67-23.72, p < 0.001) and increase in CFS (ß = 11.71, 95% CI 3.91-19.51, p = 0.004) were independently associated with increased duration of hospitalization. CONCLUSION: In patients with surgically treated brain metastases, psoas cross-sectional area was an independent risk factor for mortality and recurrence, while post-operative CFS was an independent risk factor for mortality. Post-operative frailty and increase in CFS significantly increased duration of hospitalization. Measurement of psoas cross-sectional area and CFS may aid in risk stratification of surgical candidates for brain metastases.

Long-term Prognosis in Patients With Concomitant Acute Coronary Syndrome and Aortic Stenosis.

BACKGROUND: Aortic stenosis (AS) and acute coronary syndrome (ACS) share similar cardiovascular risk factors. The incidence of concomitant AS and ACS is increasing with aging population, yet studies investigating the prognosis of these patients remain scarce. METHODS: This retrospective single-centre cohort study examined consecutive patients who presented with ACS and AS from January 1, 2011, to March 31, 2021. The cohort was divided into mild, moderate, and severe AS based on the index echocardiogram. The primary outcome was all-cause mortality. RESULTS: Of 563 patients, 264 (46.9%) had mild, 193 (34.3%) moderate, and 106 (18.8%) severe AS. The mean follow-up duration was 2.5 years. All-cause mortality was higher among patients with moderate and severe AS compared with mild AS within 30 days (17.0% vs 13.0% vs 6.4%, respectively; P = 0.005) and in the long term (49.7% vs 51.4% vs 35.6%; P = 0.002). Concomitant moderate (hazard ratio [HR] 1.453, 95% confidence interval [CI] 1.020-2.068; P = 0.038) or severe AS (HR 1.873, 95% CI 1.176-2.982; P = 0.008) was an independent predictor of all-cause mortality. Kaplan-Meier curves demonstrated higher mortality in patients with moderate and severe AS compared with mild AS (P < 0.001). Similar survival trends were observed regardless of ACS type and in those with preserved left ventricular ejection fraction. Patients with reduced left ventricular ejection fraction had poor prognosis regardless of AS severity. CONCLUSIONS: ACS patients with concomitant moderate or severe AS have similar high long-term mortality, regardless of ACS type. The high early mortality in moderate and severe AS emphasises the imperative to attempt to mitigate this risk urgently.
