Temporal trends of breast cancer burden in the Western Pacific Region from 1990 to 2044: Implications from the Global Burden of Disease Study 2019

INTRODUCTION

Breast cancer (BC) is a malignant disease that occurs worldwide and poses serious health burden.

OBJECTIVES

To assess the prevalence of BC burden in the Western Pacific region (WPR) from 1990 to 2019, and to predict trends from 2020 to 2044. To analyze the driving factors and put forward the region-oriented improvement.

METHODS

Based on the Global Burden of Disease Study 2019, BC cases, deaths, disability-adjusted life years (DALYs) cases, age-standardized incidence rate (ASIR), age-standardized death rate (ASDR), and age-standardized DALYs rate in WPR from 1990 to 2019 was obtained and analysed. Age-period-cohort (APC) model was used to analyze age, period, and cohort effects in BC, and Bayesian APC (BAPC) was used to predict trends over the next 25 years.

RESULTS

In conclusion, BC incidence and deaths in the WPR have increased rapidly over the past 30 years and are expected to continue to increase between 2020 and 2044. Among behavioral and metabolic factors, high body-mass index was the main risk factor for BC mortality in middle-income countries, whereas alcohol use was the main risk factor in Japan. Age is a key factor in the development of BC, with 40 years being the critical point. Incidence trends coincide with the course of economic development.

CONCLUSIONS

The BC burden remains an essential public health issue in the WPR and will increase substantially in the future. More efforts should be made in middle-income countries to prompt the health behavior and minimize the burden of BC because these nations accounts for the majority of BC burden in the WPR.

Awareness, attitude and barriers of colorectal cancer screening among high-risk populations in China: a cross-sectional study

OBJECTIVE

To assess the awareness, attitude and barriers of colorectal cancer screening among high-risk populations in China.

DESIGN

A cross-sectional study was employed.

SETTING

This study was conducted in nine hospitals in Hunan province, China.

PARTICIPANTS

Individuals with a high-risk for colorectal cancer were interviewed using a pretested structured questionnaire.

PRIMARY AND SECONDARY OUTCOME MEASURES

Knowledge, attitude towards colorectal cancer screening, sociodemographic factors associated with screening knowledge and behaviour and barriers of colorectal cancer screening.

RESULTS

This study included 684 participants. The mean knowledge score was 11.86/24 (SD 4.84). But over 70% of them held a positive attitude towards screening. Only 13.3% had undergone colorectal cancer screening. Independent factors related to knowledge were education level of college or above, working as a white collar, higher income, having health insurance, having seen a doctor in the past year and with a high perceived risk (p<0.05). Factors independently associated with screening behaviour included personal history of colorectal disease, having seen a doctor in the past year, previous discussion of colorectal cancer screening, high perceived risk and better knowledge (p<0.05). Main reasons for not undergoing screening were no symptoms or discomfort (71.1%), never having thought of the disease or screening (67.4%) and no doctor advised me (29.8%).

CONCLUSION

In China, the majority of high-risk people had deficient knowledge and had never undergone colorectal cancer screening. But most of them held a positive attitude towards the benefits of colorectal cancer screening. This has promising implications to design targeted educational campaigns and establish screening programmes to improve colorectal cancer awareness and screening participation. Healthcare professionals should advise high-risk individuals to participate in screening and inform them about cancer risk.

Association Between Loneliness and the Frequency of Using Online Peer Support Groups Among Cancer Patients With Minor Children: A Cross-Sectional Web-Based Study

CONTEXT

Cancer patients with minor children are increasing; however, they do not receive sufficient support.

OBJECTIVE

This study aimed to investigate the association between loneliness and the frequency of using online peer support groups among cancer patients with minor children.

METHODS

A cross-sectional web-based survey was conducted from April to May 2019. Cancer patients with minor children were recruited from an online peer support group called "Cancer Parents." Individuals diagnosed with cancer and whose youngest children were younger than 18 years were enrolled. Materials included: the UCLA Loneliness Scale version 3 (UCLA-LS), K6 scale, abbreviated Lubben Social Network Scale, and the sociodemographic/clinical characteristics questionnaire. Multivariate logistics regression analysis was performed to determine the factors associated with the high loneliness group (defined as those above the median score on the UCLA-LS).

RESULTS

A total of 334 patients participated (79.9% female; mean age 43.1 years, standard deviation 5.8). The most common primary cancer type was breast (34.1%). The median score of the UCLA-LS was 45 (interquartile range 37-53). The multivariate logistics regression analysis revealed that the high loneliness group was significantly associated with the frequent use of online peer support group less than once a week (odds ratio [OR] = 0.47; 95% CI = 0.26-0.85; P = 0.012), with a smaller social network (OR = 0.78; 95% CI = 0.73-0.83; P < 0.001), and higher psychological distress (OR = 1.16; 95% CI = 1.09-1.23; P < 0.001).

CONCLUSIONS

Frequent use of online peer support groups was associated with less loneliness among cancer patients with minor children.

Cancer burden and trends in China: A review and comparison with Japan and South Korea

Objective

To summarize the cancer burden and trends in China, compare the differences among China, Japan, and South Korea and discuss possible causes of the disparities.

Methods

Incidence and mortality data were extracted from the online cancer database including the GLOBOCAN 2018 and the Global Burden of Disease Study 2017. Trend analysis was conducted using the join-point analysis, and annual percent changes were calculated.

Results

Cancers resulted in approximately 62.9 million disability-adjusted life years (DALYs) in China in 2017. Lung cancer had the greatest contribution, followed by liver cancer, stomach cancer, and esophageal cancer. The trajectory of progress in the reduction of liver and stomach cancers was observed in China. However, China still faced a heavy burden of lung cancer and a growing burden of cancers related to westernized lifestyle such as colorectal cancer, while Japan and South Korea have achieved reductions in colorectal cancer and lung cancer, respectively. Besides, China had a lower age-standardized cancer incidence rate but higher cancer mortality and DALY rates than Japan and South Korea.

Conclusions

China is in the cancer transition stage with a rising burden of colorectal, prostate, and breast cancers along with a heavy burden of lung and upper digestive tract cancers. Taking into consideration the effectiveness of screening and tobacco control in Japan and South Korea, improvement in the current tobacco control policy and cancer screening systems may contribute to cancer control in China.
