简介：Objective:Population-basedcancerregistrationdatain2012fromallavailablecancerregistriesinGansuprovincewerecollectedbytheCentralCancerRegistryofGansu.ThenumbersofnewcancercasesandcancerdeathsinGansuprovincewithcompiledcancerincidenceandmortalityrateswereestimated.Methods:In2015,datafrom7registriesinGansuprovincewerequalified.Thepooleddatawerestratifiedbyarea(urban/rural),gender,agegroup(0,1-4,5-9,10-14,…,85+)andcancertype.Newcancercasesanddeathswereestimatedusingage-specificratesandcorrespondingpopulationofGansuprovincein2012.TheChinesecensusdatain2000andSegi'spopulationwereappliedforage-standardizedrates.Alltherateswereexpressedper100,000person-years.Results:Qualified7cancerregistries(3urbanand4ruralregistries)covered2,956,560populationsofGansuprovincein2012.Thepercentageofcasesmorphologicallyverified(MV%)anddeathcertificate-onlycases(DCO%)were72.41%and1.65%,respectively,andthemortalitytoincidencerateratio(M/I)was0.63.Itwasestimatedthattherewere575,600newcancercasesand331,300cancerdeathsinGansuprovincein2012.Theincidenceratewas223.29/100,000(244.14/100,000inmalesand201.50/100,000infemales),theage-standardizedincidenceratesbyChinesestandardpopulation(ASIRC)andbyworldstandardpopulation(ASIRW)were208.95/100,000and206.41/100,000withthecumulativeincidencerate(0-74yearsold)of22.49%.Thecrudeincidencerateinurbanareaswasequaltothatinruralareas.However,afteradjustedbyage,thecancerincidencerateinurbanwasthesameasthatofruralareas.ThecrudemortalityinGansuprovincewas128.54/100,000(135.04/100,000inmalesand124.43/100,000infemales),theage-standardizedmortalityratesbyChinesestandardpopulation(ASMRC)andbyworldstandardpopulation(ASMRW)were109.54/100,000and108.44/100,000,respectively,andthecumulativemortalityrate(0-74yearsold)was12.91%.Thecrudecancer
