Survival trends for patients with retinoblastoma between 2000 and 2018: What has changed?

INTRODUCTION: Retinoblastoma (RB) is the most common primary intraocular cancer of childhood. Over the last few decades, a variety of techniques and treatment modalities emerged that improved the survival and ocular salvage rate of patients with RB. We investigated the relative survival trends of patients with RB from 2000 to 2018 by using the Surveillance, Epidemiology, and End Results (SEER) database. DESIGN: Retrospective database review. METHODS: We extracted data from SEER 18 from 2000 to 2018. All patients with clinically diagnosed RB during the study period were included. We utilized SEER*Stat 8.3.9 and JPSurv software to estimate relative 5- and 10-year survival rates and trends and generated descriptive analyses with IBM SPSS. MAIN OUTCOME MEASURES: Patient survival rates at 5- and 10-year after RB diagnosis. RESULTS: RB was diagnosed in 1479 patients within the SEER 18 Program during our study period. The cohort comprised 776 (52.5%) males, 615 (41.6%) non-Hispanic whites, 487(32.9%) Hispanics, 1030 (69.6%) patients with unilateral disease, and 1087 (73.5%) patients with localized disease. Relative survival trends at 5- and 10-year significantly declined over the study periods (-0.42%, and -0.50% annually, respectively) but the decline was not significant in unilateral and bilateral RB cases separately. CONCLUSIONS: Five- and ten-year relative survival trends declined from 2000 to 2018 and were significantly decreasing. Further studies that include more patients are needed to identify the factors contributing to reduced survival of patients with RB over time.

The role of immunotherapy plus chemotherapy versus chemotherapy alone as first-line treatment for advanced non-small cell lung cancer: an updated systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Recently published randomized controlled trials (RCTs) showed improved overall survival (OS) and progression-free survival (PFS) with the combination of immunotherapy and chemotherapy as compared to chemotherapy alone in advanced non-small cell lung cancer (NSCLC). We aimed to provide a systematic review and meta-analysis of RCTs regarding the efficacy and safety of immunotherapy and chemotherapy combinations for advanced NSCLC. METHODS: On December 23rd, 2021, we searched databases for RCTs that reported PFS and OS as primary outcomes. RESULTS: We included 11 RCTs with 6,386 patients (3,850 in the combination therapy group and 2,536 in the chemotherapy group). Combination therapy was associated with an improvement in PFS (HR: 0.60; 95% CI: 0.54, 0.66; P < 0.00001) andOS (HR: 0.77; 95% CI: 0.68, 0.87; P ≤ 0.0001), compared to chemotherapy. There were no significant differences between both groups in terms of treatment-related adverse events (TRAEs) (RR: 1.07; 95% CI: 0.99, 1.16; P = 0.09). CONCLUSION: The combination of immunotherapy and chemotherapy as first-line treatment for advanced NSCLC significantly improved PFS and OS compared to chemotherapy alone without a significant increase in the overall TRAEs.

De-escalation from Prasugrel or Ticagrelor to Clopidogrel in Patients with Acute Coronary Syndrome Managed with Percutaneous Coronary Intervention: An Updated Meta-analysis of Randomized Clinical Trials.

INTRODUCTION: We aimed to evaluate the clinical benefits of a de-escalation strategy from prasugrel or ticagrelor to clopidogrel versus continuation of prasugrel or ticagrelor along with aspirin in both strategies for patients presenting with acute coronary syndrome (ACS) and treated with percutaneous coronary intervention (PCI), and to analyze the effect of the recently published randomized clinical trial (RCT) by Park et al., which included the largest sample size ever and the largest switched number of patients, on current guidelines and practices. DATA SOURCES: The PubMed, EMBASE, Scopus, Web of Science, Cochrane Central, and Google Scholar databases were searched systematically from inception to May 2021 by using the search terms ('de-escalation' OR 'switching') AND ('antiplatelet' OR 'clopidogrel' OR 'ticagrelor' OR 'prasugrel') AND ('percutaneous coronary intervention' OR 'PCI'' OR 'Acute coronary syndrome' OR 'ACS'). STUDY SELECTION AND DATA EXTRACTION: We included RCTs that reported the primary outcomes, i.e. net clinical benefits and Bleeding Academic Research Consortium (BARC) type 2 or higher bleeding. A combination of both ischemic and bleeding events was defined as a net clinical benefit. DATA SYNTHESIS: A total of four RCTs were included, with 5952 patients. A random-effects meta-analysis revealed that a de-escalation strategy was associated with lower ischemic and bleeding events (net clinical benefits; risk ratio [RR] 0.63, 95% confidence interval [CI] 0.47-0.85; p = 0.003), and lower BARC type 2 or higher bleeding (RR 0.51, 95% CI 0.29-0.91; p = 0.02) when compared with a continuation strategy. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: The current guidelines recommend potent P2Y12 prasugrel or ticagrelor for 12 months despite their association with a high risk of bleeding. Our meta-analysis updates cardiologists, providing them with the best available evidence in managing patients with ACS who underwent PCI. CONCLUSION: Among patients with ACS treated with PCI, a de-escalation strategy (prasugrel or ticagrelor to clopidogrel) is associated with lower ischemic and bleeding events (net clinical benefits) and lower BARC type 2 or higher bleeding; however, due to the limited number of included studies, further high-quality studies are needed to establish the clinical efficacy of the de-escalation strategy.
