Background: Both regorafenib and reduced-intensity FOLFOXIRI (riFOLFOXIRI) prolong survival in patients with metastatic colorectal cancer (mCRC). However, the sequence in which they should be administrated first in late-line treatment for refractory mCRC remains unclear. Patients and Methods: This study was a single-center retrospective cohort study that reviewed data from patients at Taipei Veterans General Hospital, Taiwan, with mCRC refractory to fluorouracil, irinotecan, oxaliplatin, cetuximab (wild-type RAS), and bevacizumab. Patients were divided into 2 groups: a regorafenib-first group and a riFOLFOXIRI-first group. The Kaplan-Meier method and log-rank test were used to analyze survival, and a Cox proportional hazards model was used for univariate, multivariate, and subgroup analyses. Results: A total of 136 and 55 patients followed a regorafenib-first or riFOLFOXIRI-first treatment strategy, respectively. At baseline, patient characteristics were similar between the groups, except for younger age in the riFOLFOXIRI-first group. The regorafenib-first group had better overall survival (13.8 vs. 10.7 mo, P=0.038), whereas patients in the riFOLFOXIRI-first group had a better partial response rate (P=0.005) but a higher rate of discontinuation due to adverse effects (P=0.004) and cross-over to regorafenib (P<0.001). Thus, no significant difference was observed in progression-free survival (regorafenib-first strategy: 3.17 mo; riFOLFOXIRI-first strategy: 4.97 mo; P=0.624). Regorafenib-first strategy, sex, and pathology were identified as independent prognostic factors. Subgroup analysis indicated that younger age, better performance status, stage IV disease, and mutant RAS gene favored the regorafenib-first strategy. Conclusion: Treatment with regorafenib-first followed by riFOLFOXIRI resulted in better overall survival when given as late-line treatment for patients with refractory mCRC.
Background: Cardiovascular dysfunction in cirrhotic patients affects survival and the development of cirrhotic complications. We aimed to evaluate potential echocardiographic parameters to predict mortality and acute kidney injury (AKI) in cirrhotic patients. Methods: A total of 103 cirrhotic patients who underwent echocardiography between February 2009 and August 2016 in Taipei Veterans General Hospital were retrospectively enrolled. Cardiac function was evaluated using transthoracic two-dimensional echocardiography with tissue Doppler imaging. Cox hazard regression analysis was used for assessing predictors for 1-year mortality and AKI within 1 year. Results: Baseline echocardiographic parameters were similar between survivors (n = 92) and nonsurvivors (n = 11). Lower serum levels of albumin, as well as higher albumin-bilirubin (ALBI) scores, Child-Pugh scores, and model for end-stage liver disease scores were observed in nonsurvivors. Cox proportional hazard regression analysis revealed Child-Pugh score as the only predictor of 1-year mortality. Baseline serum creatinine (Cr) > 1.5 mg/dL, total bilirubin > 2 mg/dL, and a higher E/e′ ratio predict occurrence of AKI within 1 year. Among patients with serum Cr < 1.5 mg/dL, an increased atrial filling velocity and higher ALBI scores predict AKI occurrence within 1 year. Conclusion: Severity of underlying liver disease but not echocardiographic parameters predicts 1-year mortality in cirrhosis. Early echocardiographic signs of diastolic dysfunction and higher ALBI scores may predict development of AKI in cirrhotic patients with serum Cr < 1.5 mg/dL.
