Clinicopathological and therapeutic comparisons of esophageal cancer between China and the USA: a multicenter hospital-based study.

Background: Esophageal cancer (EC) remains a global health challenge due to its poor prognosis. China and the United States of America (USA) represent two distinct epicenters of EC burden. Understanding the EC disparities in these two countries is vital for tailoring prevention strategies, optimizing treatment, and enhancing outcomes in both countries.

Geographic, sex and socioeconomic disparities in esophageal cancer incidence in China: A population-based study.

Geographic and sex differences in esophageal cancer have been reported in China, but data are lacking at the local level. We aimed to investigate geographic and sex disparities in esophageal cancer incidence among Chinese counties and whether county-level socioeconomic status was associated with these variations. We obtained esophageal cancer data from 2015 to 2017 for 782 counties from population-based cancer registries in China.

Racial/ethnic disparities in the cause of death among patients with prostate cancer in the United States from 1995 to 2019: a population-based retrospective cohort study.

Background: Racial/ethnic disparities in prostate cancer are reported in the United States (US). However, long-term trends and contributors of racial/ethnic disparities in all-cause and cause-specific death among patients with prostate cancer remain unclear. We analysed the trends and contributors of racial/ethnic disparities in prostate cancer survivors according to the cause of death in the US over 25 years.

Changes in Geographic Variation and Socioeconomic Inequalities in Esophageal Cancer Mortality in China, 1973-2017.

Background: Geographic variability in esophageal cancer has been reported in China, but data are lacking at the local level. We aimed to investigate changes in disparities in esophageal cancer-related mortality among Chinese counties and whether county-level socioeconomic status was associated with this variation.

Methods: We used data from a nationwide survey and population-based cancer registries to calculate esophageal cancer-related mortality rates for 782 Chinese counties for the periods of 1973-1975 and 2015-2017.

Disparities in stage at diagnosis among breast cancer molecular subtypes in China.

Background: Disease stage at diagnosis and molecular subtypes are the main determinants of breast cancer treatment strategies and prognosis. We aimed at examining the disparities and factors associated with the stage at diagnosis among the molecular subtypes in breast cancer patients in China.

Methods: We identified patients with first primary breast cancer diagnosed between January 1, 2016, and December 31, 2017, from 23 hospitals in 12 provinces in China.

Disparities in stage at diagnosis for liver cancer in China.

Background: The stage at diagnosis is a major factor in making treatment strategies and cancer control policies. However, the stage distribution for liver cancer in China was not well studied. In this multi-center hospital-based study, we aimed to identify the distribution and factors associated with stage at diagnosis for liver cancer in China.

Patterns and trends in the cause of death for patients with endometrial cancer.

Background: Racial disparities in endometrial cancer have been reported in the United States, but trends and the underlying causes are not well understood. We aimed to examine the trends and contributing factors in racial disparities for causes of death among endometrial cancer patients.

Method: In this population-based cohort study, we identified 139 473 women diagnosed with first, primary endometrial cancer between 1992 to 2018 from the Surveillance, Epidemiology, and End Results Program.

National Cancer Data Linkage Platform of China: Design, Methods, and Application.

Background: The National Cancer Center (NCC) and China CDC cooperatively designed a National Cancer Data Linkage (NCDL) Platform to fulfill the task of sharing cancer outcome data through an automatic web-based system.

Methods: NCC and China CDC established a web-based NCDL Platform to link death information from China CDC with the cancer database from NCC. Overall, 76,708 cancer patients' data were analyzed to assess the feasibility and match rate of the NCDL Platform for 7 major cancers.

Disparities in stage at diagnosis for five common cancers in China: a multicentre, hospital-based, observational study.

Background: Stage information is crucial for cancer care and essential to improve polices for cancer control. However, the distribution of stage at diagnosis for common cancers in China is not well known. We aimed to identify the distribution and factors associated with stage at diagnosis for five major cancers in China.
