Changing Patterns in Cancer Mortality from 1987 to 2020 in China

Evaluation of urban-rural difference in breast cancer mortality among Chinese women during 1987-2021: A hierarchical age-period-cohort analysis

BACKGROUND

Breast cancer mortality varies in urban and rural areas in China. Studies have reported urban-rural difference across time period, however, the evaluation on urban-rural differences in age and birth cohort effects is limited. Our aim was to quantitatively assess urban-rural disparities in age, period and cohort effects in breast cancer mortality in China.

METHODS

We collected age-specific breast cancer mortality rates for urban and rural females aged 20-84 years from 1987 to 2021. Hierarchical age-period-cohort (HAPC) models were used to evaluate the effect of area (urban, rural) on breast cancer mortality and investigate urban-rural differences in age, time period and birth cohort effects.

RESULTS

We found a significant area (urban, rural) effect on breast cancer mortality in that rural females had a lower mortality risk than urban females [-0.25 (95 % confidence interval (CI): -0.32, -0.17)]. Age trajectories of mortality based on the HAPC model showed nonlinear trends with adjustment for area variable. The urban-rural difference in age effect appeared to be divergent with age, and urban women had higher mortality risk in the senior age group. The urban-rural difference in birth cohort effect indicated a reversal around the birth cohort group of 1962-1966, after which rural females had a higher mortality risk than urban females.

CONCLUSION

The area (urban, rural) could affect breast cancer mortality among women, and the effect of urban-rural difference varies with age and birth cohort. To promote the health of urban and rural females, the gap between urban and rural areas should be shorten.

Suicidal ideation in Chinese patients with advanced breast cancer: a multi-center mediation model study

PURPOSE

The pathways underpinning suicide ideation (SI) and certain physical and psychological factors in patients with advanced breast cancer remain unclear. This study develops and validates a mediation model that delineates the associations between several multidimensional variables and SI in Chinese patients with advanced breast cancer.

METHODS

Patients with advanced breast cancer (n = 509) were recruited as study participants from 10 regional cancer centers across China from August 2019 to December 2020. Participants were required to complete five questionnaires using an electronic patient-reported outcomes (ePRO) system: 9 item- Patient Health Questionnaire (PHQ-9), Hospital Anxiety and Depression Scale (HADS), Insomnia Severity Index (ISI), 5-level EQ-5D (EQ-5D-5L), and MD Anderson Symptom Inventory (MDASI). Risk factors for SI were identified using multivariable logistic regression, and inputted into serial multiple mediation models to elucidate the pathways linking the risk factors to SI.

RESULTS

SI prevalence was 22.8% (116/509). After adjusting for covariates, depression (odds ratio [OR] = 1.384), emotional distress (OR = 1.107), upset (OR = 0.842), and forgetfulness (OR = 1.236) were identified as significant independent risk factors (all p < 0.05). The ORs indicate that depression and distress have the strongest associations with SI. Health status has a significant indirect effect (OR=-0.044, p = 0.005) and a strong total effect (OR=-0.485, p < 0.001) on SI, mediated by insomnia severity and emotional distress.

CONCLUSIONS

There is a high SI prevalence among Chinese patients with advanced breast cancer. Our analysis revealed predictive pathways from poor health to heightened SI, mediated by emotional distress and insomnia. Regular management of distress and insomnia can decrease suicide risk in this vulnerable population.

Cancer profiles in China and comparisons with the USA: a comprehensive analysis in the incidence, mortality, survival, staging, and attribution to risk factors

China faces a disproportionate cancer burden to the population size and is undergoing a transition in the cancer spectrum. We extracted data in five aspects of cancer incidence, mortality, survival, staging distributions, and attribution to risk factors in China, the USA and worldwide from open-source databases. We conducted a comprehensive secondary analysis of cancer profiles in China in the above aspects, and compared cancer statistics between China and the USA. A total of 4,546,400 new cancer cases and 2,992,600 deaths occurred in China in 2020, accounting for 25.1% and 30.2% of global cases, respectively. Lifestyle-related cancers including lung cancer, colorectal cancer, and breast cancer showed an upward trend and have been the leading cancer types in China. 41.6% of new cancer cases and 49.3% of cancer deaths occurred in digestive-system cancers in China, and the cancers of esophagus, nasopharynx, liver, and stomach in China accounted for over 40% of global cases. Infection-related cancers showed the highest population-attributable fractions among Chinese adults, and most cancers could be attributed to behavioral and metabolic factors. The proportions of stage I for most cancer types were much higher in the USA than in China, except for esophageal cancer (78.2% vs. 41.1%). The 5-year relative survival rates in China have improved substantially during 2000-2014, whereas survival for most cancer types in the USA was significantly higher than in China, except for upper gastrointestinal cancers. Our findings suggest that although substantial progress has been made in cancer control, especially in digestive system cancers in China, there was still a considerable disparity in cancer burden between China and the USA. More robust policies on risk factors and standardized screening practices are urgently warranted to curb the cancer growth and improve the prognosis for cancer patients.

Age-Period-Cohort Analysis on Long-Term Mortality Trend of Genitourinary Diseases - China, 1987-2021

What is already known about this topic?

There has been a lack of attention to genitourinary diseases for an extended period, resulting in limited research on the mortality trends of genitourinary diseases in China.

What is added by this report?

This study examines the long-term trend of genitourinary diseases' mortality across Chinese individuals of all genders and in various urban and rural regions. Additionally, it investigates the impact of age-period-cohort effects on this trend.

What are the implications for public health practice?

It is imperative to address genitourinary diseases, particularly among vulnerable populations such as rural older men. Policymakers should prioritize these individuals by providing necessary policy interventions and healthcare support.

The concept of spirituality in the context of Chinese patients with cancer: A scoping review

AIM

To elucidate how the concept of spirituality has been addressed in studies with Chinese people with cancer.

DESIGN

A scoping review.

METHODS

Patterns in conceptual definitions of spirituality and indicators for measuring spirituality were analysed.

DATA SOURCES (INCLUDE SEARCH DATES)

Literature published from inception to August 2022 was searched in five electronic databases (CINAHL, PubMed, Web of Science, PsycINFO and a Chinese database).

RESULTS

Using data from 10 qualitative studies, a new taxonomy of concepts of spirituality among Chinese people with cancer was derived, consisting of four categories: Creation of meaning, Connection, Transcendence and Existence. A total of 12 instruments developed outside of Chinese contexts and used to measure dimensions of spirituality across 27 quantitative studies were compared to the taxonomy developed in this review, and patterns were identified according to the dimensions of spirituality. Several instruments required modifications or additional explanations in questions regarding God/Higher Power and religion.

CONCLUSION

The four categories of spirituality classified in the current review are considered universal across all cultural contexts. Spirituality is multidimensional and functional concept, and the components of the instruments differed depending on which dimension of spirituality was being measured.

IMPACT

The findings of this study suggest that for measuring spirituality in research and clinical settings with Chinese people with cancer, it is important to use culturally appropriate scales that are consistent with the dimensions of spirituality being measured.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

Even instruments developed outside of the Chinese context could be used for Chinese people with cancer if appropriately selected for their intended use.
