ObjectiveTo understand the latest epidemiological situation of liver cancer worldwide and in China. MethodsThis team organized and briefly interpreted the results of the two reports, the International Agency for Research on Cancer team released the latest global cancer statistics report in its authoritative journal, CA: A Cancer Journal for Clinicians, in April 2024, the research team from the National Center for Chronic and Noncommunicable Disease Control and Prevention at the Chinese Center for Disease Control and Prevention published an article in the Lancet Public Health on the changes in cancer burden in China from 2005 to 2020. The epidemiological trends of liver cancer worldwide and in China from 2018 to 2022, the changes in age-standardized incidencerate by world standard population (ASIRW) and age-standardized mortality rate by world standard population (ASMRW) of liver cancer in countries with different human development index (HDI) and income levels in the world in 2022, the incidence and death of liver cancer in different age groups in the world and China in 2022, and the changes in the disease burden of liver cancer in China from 2005 to 2020 were anlyzed. ResultsIn 2022, there were 865 269 new cases and 757 948 deaths of liver cancer globally, it was the sixth most common malignancy and the third leading cause of cancer-related deaths worldwide. The incidence and mortality of liver cancer worldwide and in China from 2018 to 2022 tended to be stable or declining, which in men were higher than those in women, and which in all population and males in China were higher than those in the world. The ASIRW and ASMRW were the highest in the countries with high HDI and upper-middle income levels. With the increase of age, the ASIRW and ASMRW of liver cancer continued to increase in the world and in China. The average annual percentage changes (AAPCs) in the deaths, ASMRW, year of life loss, and age-standardized year of life loss for all age groups in China from 2005 to 2020 were negative, indicating a downward trend for each of these indicators. The ASMRW of liver cancer increased with the increasing of age in 2020 in China. ConclusionsLiver cancer continues to pose a significant disease burden worldwide and in China. Therefore, implementing primary and secondary prevention strategies for liver cancer in the future is a major measure for its prevention and control. Additionally, continuous efforts are needed to ensure multidisciplinary and standardized management of liver cancer throughout its course.
Objective To explore the effect of multimodal interventions in improving the compliance rate of core infection control measures on reducing the incidence rate of vessel catheter associated infection (VCAI). Methods Inpatients with intravascular catheters in 5 departments with high rates of vascular catheterization and infection of Dongguan People’s Hospital between January 2021 and December 2022 were selected. According to the hospital stay, patients were divided into a pre-intervention group (January to December 2021) and a post-intervention group (January to December 2022). The core infection control measures assessment pass rates of medical staff between the two periods and the differences in the incidence rate of VCAI, average catheterization days, and catheterization rate before and after intervention in both groups were compared. Results A total of 8174 patients were included. Among them, there were 3915 patients in the pre-intervention group and 4259 patients in the post-intervention group. In the pre-intervention group, the total length of hospital stay was 122885 days, the total number of catheterization days was 48028 days, and 28 cases of VCAI occurred. In the post-intervention group, the total length of hospital stay was 126966 days, the total number of catheterization days was 51253 days, and 12 cases of VCAI occurred. After intervention, the compliance rate of VCAI core infection control measures was improved [69.21% (2907/4200) vs. 91.24% (3832/4200); χ2=642.090, P＜0.001], the pass rate of medical staff’s core infection control measures assessment was improved [53.33% (128/240) vs. 91.67% (220/240); χ2=88.443, P＜0.001], the catheterization rate was increased [39.08% (48028/122885) vs. 40.37% (51253/126966); χ2=42.979, P<0.001], and the incidence rate of VCAI was reduced [0.58‰ (28/48028) vs. 0.23‰ (12/51253); incidence-rate ratios =0.40, 95% confidence interval (0.20, 0.79), P=0.008]. Conclusions Improving the compliance rate of VCAI core infection control measures through multimodal interventions can significantly improve the passing rates of core infection control measures of medical staffs. This will help to reduce the incidence of VCAI and ensuring patient safety, provide evidence-based support for the prevention and control of VCAI.
Objective To summary the incidence rate and trends of malignant tumor in China. MethodsBy compiling and analyzing the Chinese Cancer Registry Annual Report from 2008 to 2021, we summarized the regional and population distribution characteristics of overall and high-incidence rate malignant tumors in China and analyzed influencing factors. ResultsFrom 2005 to 2018, the overall crude incidence of malignant tumors in China showed a continuous upward trend. The incidence rate in the eastern region (incidence rate was 353.26/100 000 in 2018; hereafter the same) was significantly higher than those in the central (269.47/100 000) and western regions (253.71/100 000), while the incidence rates in the central and western regions were closer. 2005–2018, the incidence rate of males was higher than that of females, and the population aged 80 years old or older (2 741.02/100 000) had the highest incidence rate of malignant tumors, and the incidence rate of people aged 0–14 years (41.38/100 000) was the lowest. From 2005–2018 (except for 2009), lung cancer (65.05/100 000), gastric cancer (27.03/100 000), liver cancer (27.42/100 000), colorectal cancer (30.51/100 000), and breast cancer (43.02/100 000) were the top 5 highest incidence rates of China’s malignant tumors, of which lung cancer ranked the first in different regions, and the ranking of other cancers varied in different regions. The top 5 tumors in males incidence rate from 2005 to 2018 were lung cancer (83.45/100 000), gastric cancer (37.12/100 000), liver cancer (40.02/100 000), colorectal cancer (35.32/100 000) and esophageal cancer (26.30/100,000); the top 5 tumors in females incidence rate had changed a lot in different years, breast cancer, lung cancer, colorectal cancer, gastric cancer, liver cancer, thyroid cancer and cervical cancer had all been in the top 5, for example, in 2018, the top 5 malignant tumors in females were lung cancer (46.10/100 000), breast cancer (43.02/100 000), colorectal cancer (25.56/100 000), thyroid cancer (24.60/100 000) and cervical cancer (18.10/100 000). ConclusionsThe crude incidence rate of malignant tumors in China continues to rise, with the cancer spectrum showing new characteristics that combine high-incidence rate cancers in developed countries (e.g., breast cancer, colorectal cancer) with common cancers in developing countries (e.g., gastric cancer, liver cancer). The situation of malignant tumor prevention and control remains challenging.
