This study assesses the magnitude of survival disparities and separates the role of stage at diagnosis between a Chinese metropolitan city and the USA for all cancers and 20 individual cancer types. Methods: Newly diagnosed patients from Dalian Cancer Registry (2015; 11,046 cases) were followed for vital status through December 2020 to estimate age-standardised 5-year relative survival and excess hazard ratios using generalized linear models. Stage-specific survival for five major cancers was also estimated by region and compared with 17 US cancer registries from the SEER database. Findings: Overall 5-year relative survival was lower in Dalian than in the USA (49.9% vs 67.9%). By cancer type, 12 cancers had poorer outcomes in Dalian, with the largest gap for prostate cancer, while Dalian showed better survival for lung, cervical, and bladder cancers. Interpretation: Although the USA had better overall prognosis, survival deficits existed in both countries, highlighting needs for improved early detection and cancer care in both settings.",{"@graph":69,"@context":126},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":35,"@type":76,"position":81},"https://docshare.wps.com/document/healthcare/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/survival-differences-between-the-usa-and-an-urban-population-from-china-for-all-cancer-types-and-20-individual-cancers-a-population-based-study/381600/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/survival-differences-between-the-usa-and-an-urban-population-from-china-for-all-cancer-types-and-20-individual-cancers-a-population-based-study/381600.png","ImageObject",300,407,{"name":92,"@type":93},"Chumphorn","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-29","2026-09-24",true,{"@type":102,"interactionType":103,"userInteractionCount":39},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118,122],{"name":109,"@type":110,"acceptedAnswer":111},"What was the main purpose of comparing cancer survival between China and the USA?","Question",{"text":112,"@type":113},"The study quantified survival disparities and clarified how much differences relate to stage at diagnosis between a Chinese metropolitan city and the USA.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How was survival measured in this research?",{"text":117,"@type":113},"Age-standardised 5-year relative survival was estimated, and excess hazard ratios of death were calculated using generalized linear models.

Here we aimed to assess the magnitude of survival disparities and disentangle the impact of the stage at diagnosis between a Chinese metropolitan city and the USA on cancer survival.  \nMethods We included 11,046 newly diagnosed cancer patients in Dalian Cancer Registry, China, 2015, with the follow-up data for vital status until December 2020 . We estimated age-standardised 5-year relative survival and quantified the excess hazard ratio (EHR) of death using generalised linear models for all cancers and 20 individual cancers. We compared these estimates with 17 cancer registries’ data from the USA, using the Surveillance, Epidemiology, and End Results database. We further estimated the stage-specific survival for five major cancers by region.  \nFindings Age-standardised 5-year relative survival for all patients in Dalian was lower than that in the USA (49.9% vs 67.9%) . By cancer types, twelve cancers with poorer prognosis were observed in Dalian compared to the USA, with the largest gap seen in prostate cancer (Dalian: 55.8% vs USA: 96.0%) . However, Dalian had a better survival for lung cancer, cervical cancer, and bladder cancer. Dalian patients had a lower percentage of stage I colorectal cancer (Dalian: 17.9% vs USA: 24.2%) and female breast cancer (Dalian: 40.9% vs USA: 48.9%) . However, we observed better stagespecific survival among stage I-II lung cancer patients in Dalian than in the USA.  \nInterpretation This study suggests that although the overall prognosis for patients was better in the USA than in Dalian, China, survival deficits existed in both countries. Improvement in cancer early detection and cancer care are needed in both countries.  \nAbbreviations: AJCC, American Joint Committee on Cancer; CI, Confidence interval; EHR, Excess hazard ratio; GDP, Gross Domestic Product; ICD-10","cbCairWpeenrf95q","https://ap.wps.com/l/cbCairWpeenrf95q","pdf",822061,13,"English","# Background\n# Methods\n# Findings\n# Interpretation\n# Keywords","[{\"question\":\"What was the main purpose of comparing cancer survival between China and the USA?\",\"answer\":\"The study quantified survival disparities and clarified how much differences relate to stage at diagnosis between a Chinese metropolitan city and the USA.\"},{\"question\":\"How was survival measured in this research?\",\"answer\":\"Age-standardised 5-year relative survival was estimated, and excess hazard ratios of death were calculated using generalized linear models.
