Global colorectal cancer research, 2007-2021: Outputs and funding

The purpose of this study was to provide an evidence base for colorectal cancer research activity that might influence policy, mainly at the national level. Improvements in healthcare delivery have lengthened life expectancy, but within a situation of increased cancer incidence. The disease burden of CRC has risen significantly, particularly in Africa, Asia and Latin America. Research is key to its control and reduction, but few studies have delineated the volume and funding of global research on CRC. We identified research papers in the Web of Science (WoS) from 2007 to 2021, and determined the contributions of the leading countries, the research domains studied, and their sources of funding. We identified 62 716 papers, representing 5.7% of all cancer papers. This percentage was somewhat disproportionate to the disease burden (7.7% in 2015), especially in Eastern Europe. International collaboration increased over the time period in almost all countries except in China. Genetics, surgery and prognosis were the leading research domains. However, research on palliative care and quality-of-life in CRC was lacking. In Western Europe, the main funding source was the charity sector, particularly in the UK, but in most other countries government played the leading role, especially in China and the USA. There was little support from industry. Several Asian countries provided minimal contestable funding, which may have reduced the impact of their CRC research. Certain countries must perform more CRC research overall, especially in domains such as screening, palliative care and quality-of-life. The private-non-profit sector should be an alternative source of support.     

携带同源重组修复相关基因突变的消化道肿瘤的临床特点

目的:探讨消化道肿瘤中同源重组修复相关基因(homologous recombination repair related gene，HRR)突变的发生情况及临床意义。方法:共92例消化道肿瘤患者，79例患者进行了血液标本HRR检测，53例患者进行了组织标本HRR检测，40例患者同时行血液和组织的HRR基因检测，收集患者基因检测结果及临床相关资料。结果:在79例患者血液标本检测中发现10例（12.6%）有临床意义HRR突变，在53例患者组织标本检测中发现9例（17.0%）有临床意义HRR突变。40例同时行血液和组织的HRR基因检测患者中常见的有临床意义HRR突变为CDK12突变4例（10.0%）、ATM突变3例（7.5%）、BRCA1突变2例（5.0%）。13例有临床意义HRR突变患者中常见共存突变为TP53突变10例（76.9%）、APC突变5例（38.5%）、PIK3CA突变4例（30.8%）。40例患者中13例患者血液和/或组织中有临床意义HRR突变，27例患者血液和组织中均无任何临床意义HRR突变且两组相比，有临床意义HRR突变组肿瘤突变负荷（tumor mutational burden，TMB）为6.17(2.24～11.52)，而未携带HRR突变组TMB为0.4(0～3.75)，差异有统计学意义（P＜0.05）。40例患者组织检测中7例HRR有临床意义的突变，33例无HRR突变，血液检测中10例HRR有临床意义的突变，30例无HRR突变，一致性检验的Kappa值为0.333（P=0.031）。结论:携带有临床意义HRR突变的消化道肿瘤患者TMB更高，血液和组织检测HRR突变有较好的一致性。     

Impact of Adding Oseltamivir to Usual Care on Quality-Adjusted Life-Years During Influenza-Like Illness

ObjectivesThe ALIC⁴E trial has shown that oseltamivir reduces recovery time while increasing the risk of nausea. This secondary analysis of the ALIC⁴E trial aimed to determine the gain in quality-adjusted life-years (QALYs) associated with adding oseltamivir to usual primary care in patients presenting with influenza-like illness (ILI).MethodsPatients with ILI were recruited during the influenza season (2015-2018) in 15 European countries. Patients were assigned to usual care with or without oseltamivir through stratified randomization (age, severity, comorbidities, and symptom onset). Patients’ health status was valued with the EQ-5D and visual analog scale (VAS) for up to 28 days. Average EQ-5D and VAS scores over time were estimated for both treatment groups using one-inflated beta regression in children (<13 years old) and adults (≥13 years old). QALY gain was calculated as the difference between the groups. Sensitivity analysis considered the value set to convert EQ-5D answers to summary scores and the follow-up period.ResultsIn adults, oseltamivir gained 0.0006 (95% confidence interval 0.0002-0.0010) QALYs, whereas no statistically significant gain was found in children (14-day follow-up, EQ-5D). QALY gains were statistically significant in patients aged ≥65 years, patients without relevant comorbidities, or patients experiencing symptoms for ≤48 hours. Using VAS and accounting for 28-day follow-up resulted in higher QALY gain.ConclusionsQALY gain owing to oseltamivir is limited compared with other diseases, and its clinical meaningfulness remains to be determined. Further analysis is needed to evaluate whether QALY gain and its impact on ILI treatment cost render oseltamivir cost-effective.
