ABSTRACT

BACKGROUND: Immune checkpoint inhibitors (ICIs) are approved for multiple cancers but can result in ICI-associated myocarditis, an infrequent but life-threatening condition. Elevations in cardiac biomarkers, specifically troponin-I (cTnI), troponin-T (cTnT), and creatine kinase (CK), are used for diagnosis. However, the association between temporal elevations of these biomarkers with disease trajectory and outcomes has not been established.

METHODS: We analyzed the diagnostic accuracy and prognostic performances of cTnI, cTnT, and CK in patients with ICI myocarditis (n=60) through 1-year follow-up in 2 cardio-oncology units (APHP Sorbonne: Paris, France and Heidelberg, Germany). A total of 1751 (1 cTnT assay type), 920 (4 cTnI assay types), and 1191 CK sampling time points were available. Major adverse cardiomyotoxic events (MACE) were defined as heart failure, ventricular arrhythmia, atrioventricular or sinus block requiring pacemaker, respiratory muscle failure requiring mechanical ventilation, and sudden cardiac death. Diagnostic performance of cTnI and cTnT was also assessed in an international ICI myocarditis registry.

RESULTS: Within 72 hours of admission, cTnT, cTnI, and CK were increased compared with upper reference limits (URLs) in 56 of 57 (98%), 37 of 42 ([88%] P=0.03 versus cTnT), and 43 of 57 ([75%] P<0.001P<0.001)P<0.001),P<0.001),

CONCLUSIONS: cTnT is associated with MACE and is sensitive for diagnosis and surveillance in patients with ICI myocarditis. A cTnT:URL ratio <32

Comparing Renin-Angiotensin-Aldosterone Blockade Regimens for Long-Term Chemotherapy-Related Cardiac Dysfunction: A Network Meta-Analysis

Cardiovasc Drugs Ther. 2023 Jun 14. doi: 10.1007/s10557-023-07457-w. Online ahead of print.

ABSTRACT

PURPOSE: Cancer therapies including trastuzumab and anthracyclines are cardiotoxic and cause cardiac dysfunction. To prevent cardiotoxicity, pharmacological agents used in heart failure have been administered concomitantly with cardiotoxic cancer therapy, but few studies to date have performed a head-to-head comparison of these different agents. This systematic review and network meta-analysis of randomized-controlled trials aims to evaluate the efficacy of renin-angiotensin-aldosterone system (RAAS) blockers, namely angiotensin-converting enzyme inhibitors (ACE-Is), aldosterone receptor blockers (ARBs), and mineralocorticoid receptor antagonists (MRAs), in primary prevention against chemotherapy-related cardiac dysfunction in patients receiving anthracyclines and/or trastuzumab.

METHODS: A systematic search was performed in major web databases for studies from inception to 15 September 2022. A Bayesian network meta-analysis model was used to assess the relative effects of competing treatments on the primary outcomes of risk of significant decline in left ventricular ejection fraction (LVEF) and mean LVEF decline. Secondary outcomes included left ventricular diastolic function, global longitudinal strain, and cardiac biomarkers. This study is registered with PROSPERO, CRD42022357980.

RESULTS AND CONCLUSION: Nineteen studies reported the effects of 13 interventions (N = 1905 patients). Only enalapril (RR 0.05, 95% CI 0.00-0.20) was associated with reduced risk of patients developing significant decline in LVEF relative to placebo. Subgroup analysis showed that the beneficial effect of enalapril was driven by protection against anthracycline-associated toxicity. In addition, no RAAS-inhibiting agents showed efficacy in protection against treatment with both anthracycline and trastuzumab. The use of RAAS inhibition therapy did not conclusively impact on other markers of cardiac function, including left ventricular diastolic function and cardiac biomarkers.

First-line systemic treatment strategies in patients with initially unresectable colorectal cancer liver metastases (CAIRO5): an open-label, multicentre, randomised, controlled, phase 3 study from the Dutch Colorectal Cancer Group

Lancet Oncol. 2023 Jun 14:S1470-2045(23)00219-X. doi: 10.1016/S1470-2045(23)00219-X. Online ahead of print. ABSTRACTBACKGROUND: Patients with initially unresectable colorectal cancer liver metastases might qualify for local treatment with curative intent after reducing the tumour size by induction systemic treatment. We aimed to compare the currently most active induction regimens.

METHODS: In this open-label, multicentre, randomised, phase 3 study (CAIRO5), patients aged 18 years or older with histologically confirmed colorectal cancer, known RAS/BRAFV600E mutation status, WHO performance status of 0-1, and initially unresectable colorectal cancer liver metastases were enrolled at 46 Dutch and one Belgian secondary and tertiary centres. Resectability or unresectability of colorectal cancer liver metastases was assessed centrally by an expert panel of liver surgeons and radiologists, at baseline and every 2 months thereafter by predefined criteria. Randomisation was done centrally with the minimisation technique via a masked web-based allocation procedure. Patients with right-sided primary tumour site or RAS or BRAFV600E mutated tumours were randomly assigned (1:1) to receive FOLFOX or FOLFIRI plus bevacizumab (group A) or FOLFOXIRI plus bevacizumab (group B). Patients with left-sided and RAS and BRAFV600E wild-type tumours were randomly assigned (1:1) to receive FOLFOX or FOLFIRI plus bevacizumab (group C) or FOLFOX or FOLFIRI plus panitumumab (group D), every 14 days for up to 12 cycles. Patients were stratified by resectability of colorectal cancer liver metastases, serum lactate dehydrogenase concentration, choice of irinotecan versus oxaliplatin, and BRAFV600E mutation status (for groups A and B). Bevacizumab was administered intravenously at 5 mg/kg. Panitumumab was administered intravenously at 6 mg/kg. FOLFIRI consisted of intravenous infusion of irinotecan at 180 mg/m2 with folinic acid at 400 mg/m2, followed by bolus fluorouracil at 400 mg/m2 intravenously, followed by continuous infusion of fluorouracil at 2400 mg/m2. FOLFOX consisted of oxaliplatin at 85 mg/m2 intravenously together with the same schedule of folinic acid and fluorouracil as in FOLFIRI. FOLFOXIRI consisted of irinotecan at 165 mg/m2 intravenously, followed by intravenous infusion of oxaliplatin at 85 mg/m2 with folinic acid at 400 mg/m2, followed by continuous infusion of fluorouracil at 3200 mg/m2. Patients and investigators were not masked to treatment allocation. The primary outcome was progression-free survival, analysed on a modified intention-to-treat basis, excluding patients who withdrew consent before starting study treatment or violated major entry criteria (no metastatic colorectal cancer, or previous liver surgery for colorectal cancer liver metastases). The study is registered with ClinicalTrials.gov, NCT02162563, and accrual is complete.

FINDINGS: Between Nov 13, 2014, and Jan 31, 2022, 530 patients (327 [62%] male and 203 [38%] female; median age 62 years [IQR 54-69]) were randomly assigned: 148 (28%) patients to group A, 146 (28%) patients to group B, 118 (22%) patients to group C, and 118 (22%) patients to group D. Groups C and D were prematurely closed for futility. 521 patients were included in the modified intention-to-treat population (147 in group A, 144 in group B, 114 in group C, and 116 in group D). The median follow-up at the time of this analysis was 51·1 months (95% CI 47·7-53·1) in groups A and B and 49·9 months (44·5-52·5) in in groups C and D. [...]
