RESUMEN

Breast Cancer (BC) is one of the most common cancers diagnosed in population femmale and it has several subtypes, one of them being theexpressing human epidermal growth factor receptor 2 positive (HER2 +), one of the treatments for HER2+ breast cancer consists of chemotherapy plus trastuzumab deruxtecan. Several clinical trials have shown the effectiveness and safety of trastuzumabe deruxtecano in cancer patients, however, several Adverse Events (AEs) have been described and the decrease in left ventricular ejection has been singled out for more prominent analysis. Objective: We conducted a systematic review and meta-analysis to investigate the cardiovascular effects of Trastuzumab Deruxtecano and whether it can influence the appearance of reduced left ventricular ejection fraction.. METHODS: We performed a systematic search in Embase, PubMed and Cochrane databases for randomized controlled trials (RCTs) showed a decrease in left ventricular ejection fraction in patients using trastuzumab deruxtecan against Her-2-positive breast cancer compared to patients to used another's treatments against this disease. Mean difference (MD) with 95% confidence intervals (CI) were calculated using a random effects model. The heterogeneity was examined in the I2 statistic. P-values > 0.05 were considered statistically significant. The statistical analysis was carried out using R software version 4.2.3. RESULTS: A total of 3 RCTs were included, with a total of 1656 patients evaluated, 928 patients randomized to the use of Trastuzumab Deruxtecan and 728 patients to the use of other treatments according to medical choice, follow-up ranged from 10 to 38 months. There was a visible in the decrease in left ventricular ejection fraction, with a higher incidence in the group that used trastuzumab compared to the placebo group (RR: 5.73%; 95% CI 1.51 - 21.78; I2 33% ; P= 0.010466). Another important point is the discontinuation of treatment due to grade 2 adverse events, classified as reduced LVEF, where a higher incidence is seen in the group that used Trastuzumab Deruxtecan compared to the placebo group (RR 2.11%; 95% CI 1.54 - 2.89; P = 0.000003),7. CONCLUSION: In this meta-analysis, Trastuzumab Deruxtecan showed a relationship with a decrease in left ventricular ejection fraction, displaying the need for more studies to evaluate the cardiotoxicity of trastuzumab and its effects as a whole on the cardiovascular system.

RESUMEN

BACKGROUND Atherosclerotic cardiovascular disease (ASCVD), affects approximately 18.6 million individuals worldwide and poses a significant healthcare related challenge. Despite the established efficacy of both high-intensity statin monotherapy (HIS) and moderate-intensity statin plus ezetimibe (MIS+EZT) in ASCVD management, the optimal treatment strategy remains unclear. METHODS A thorough literature study was conducted across PubMed, Embase, and the Cochrane databases, focusing on studies that compared the effects of moderate-intensity statins plus ezetimibe with high-intensity statin monotherapy in ASCVD patients. RESULTS In the 13 included studies, involving 8,592 patients, 4,525 (52.67%) of which received moderate-intensity statin plus ezetimibe treatment. The follow-up period ranged from 4 to 156 weeks, with participant ages varying LDL-C from 55.2 to 71 years old. Analysis revealed significant MIS+EZT-associated with greater percentages of patients achieved the goal in Low-Density Lipoprotein (LDL-C) < 70 (Odds Ratio (OR) 1.76; 95% CI [1.26; 2.45]; p=0.001; I²=73%), LDL-C reduction (Mean Difference (MD) -5.05 mg/dL; 95% CI [-9.02;-1.07]; p<0.013; I²=56%;); Total Cholesterol reduction (MD -7.91 mg/ dL; 95% CI [-14.90; -0.91]; p<0.027; I²=60%); Triglycerides reduction (MD -8.20 mg/ dL; 95% CI [-13.05; -3.35]; p<0.001; I²=2%;); There was no statistical difference between groups in Drug Adverse reaction (Risk Ratio (RR) 1.19; 95% CI [0.79; 1.78]; p=0.404; I²=0%); and Drug intolerance (RR 0.78; 95% CI [0.32; 1.92]; p=0.584; I²=35%). CONCLUSIONS This meta-analysis highlights the effectiveness of MIS+EZT in improving significant lipid profile components for ASCVD patients, as can been seen through the greater percentage of patients achieving the LDL-C <70 mg/dL target and lower LDL-C, total cholesterol and triglycerides levels. Importantly, there were no significant differences in the occurrence of overall adverse events and adverse drug reactions between the two groups.

RESUMEN

BACKGROUND: Dual antiplatelet therapy (DAPT) with clopidogrel plus aspirin is a well-established practice after a minor stroke or transient ischemic attack (TIA). However, ticagrelor plus aspirin may be an alternative. AIMS: We systematically searched PubMed, Embase, and Cochrane Central from inception to January 2024. We included randomized controlled trials (RCTs) enrolling adults with acute minor stroke or TIA within 72 hours of the onset of the symptoms. RESULTS: A total of 8 RCTs were included in our meta-analysis. Ticagrelor plus aspirin (RR, 0.70; 95% CrI 0.52, 0.91) and clopidogrel plus aspirin (RR, 0.79; 95% CrI 0.64, 0.98) were superior to aspirin in preventing stroke recurrence in overall analysis. Excluding studies with dual antiplatelet up to 90 days, ticagrelor plus aspirin was the only strategy that maintained superiority compared with aspirin regarding stroke recurrence (RR, 0.70; 95% CrI 0.51, 0.95) and ischemic stroke (RR, 0.68; 95% CrI 0.47, 0.94). There was no significant difference between treatment groups regarding hemorrhagic stroke, functional disability, and mortality. CONCLUSIONS: DAPTs were superior to aspirin in preventing recurrence or ischemic stroke. Although no significant difference was observed between DAPTs, ticagrelor plus aspirin may be related to worse major bleeding results, including intracranial bleeding. Ticagrelor plus aspirin is a considerable option for patients after a minor stroke or TIA.

RESUMEN

Background: The benefit of adding programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) inhibitors to the treatment of early-stage non-small cell lung cancer (NSCLC), both neoadjuvant therapy (NAT) and adjuvant therapy (AT), is not yet fully elucidated. Methods: We searched PubMed, Embase, and Cochrane databases for randomized controlled trials (RCT) that investigated PD-1/PD-L1 inhibitors plus chemotherapy for resectable stage NSCLC. We computed hazard ratios (HRs) or odds ratios (ORs) for binary endpoints, with 95% confidence intervals (CIs). Results: A total of seven RCTs comprising 3915 patients with resectable stage NSCLC were randomized to chemotherapy with or without PD-1/PD-L1 inhibitors as NAT or AT. As NAT, the PD-1/PD-L1 inhibitors plus chemotherapy group demonstrated significantly improved overall survival (HR 0.66; 95% CI 0.51-0.86) and event-free survival (HR 0.53; 95% CI 0.43-0.67) compared with the chemotherapy alone group. There was a significant increase in favor of the PD-1/PD-L1 inhibitors plus chemotherapy group for major pathological response (OR 6.40; 95% CI 3.86-10.61) and pathological complete response (OR 8.82; 95% CI 4.51-17.26). Meanwhile, as AT, disease-free survival was significant in favor of the PD-1/PD-L1 inhibitors plus chemotherapy group (HR 0.78; 95% CI 0.69-0.90). Conclusions: In this comprehensive systematic review and meta-analysis of RCTs, the incorporation of PD-1/PD-L1 inhibitors alongside chemotherapy offers a promising prospect for reshaping the established treatment paradigms for patients diagnosed with resectable stages of NSCLC. Moreover, our analyses support that neoadjuvant administration with these agents should be encouraged, in light of the fact that it was associated with an increased survival and pathological response, at the expense of a manageable safety profile.
