Siden da er det etablert 12 kvalitetsregistre, hvorav åtte har nasjonal godkjenning. Utvikling av kvalitetsregistrene har gått stegvis, og de første årene var oppgaven å definere hvilket dataomfang som var relevant for de ulike registrene. Utvikling av tekniske løsninger for innregistrering sto også sentralt i satsningen. I senere år har det vært stor oppmerksomhet rundt formidling av resultatene og konsekvenser for klinisk praksis.\u0000For hvert kvalitetsregister er det i dag en kvalitetsregisteransvarlig, en statistiker og et fagråd bestående av klinikere og forskere med relevant kompetanse. Pasientmedvirkning er organisert gjennom et brukerpanel der alle relevante pasientforeninger er representert. Arbeidet med kvalitetsregistrene er dessuten koordinert på tvers av kreftformer.\u0000Fra 2016 har utvalgte resultater blitt presentert som kvalitetsindikatorer med måltall og sammen med fagrådenes tolkning har disse blitt målrettet formidlet til de ulike helseforetakene.

Since then, 12 clinical registries have been established. The development of clinical registries has been a gradual process. The first years, the task was to define which information was relevant for the different cancer sites. Development of technical solutions for reporting was also a key issue.\u0000The organization around the clinical registries has been built up over several years. For each clinical registry, there is a registry manager, a statistician and a professional council consisting of clinicians and researchers with relevant competence. In addition, the clinical registries are coordinated across cancers. Representation from patient associations is organized in a user panel.\u0000From 2016, the establishment of quality indicators was put on the agenda. This has been the most important measure for the development of the clinical registries in the Cancer Registry. Quality indicators, results presented for each hospital and the professional councils' interpretation of the results, have been purposefully communicated to the health trusts. In recent years, several hospitals have changed their clinical practice based on results from the clinical registries in the Cancer Registry.","PeriodicalId":35548,"journal":{"name":"Norsk Epidemiologi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41400400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Det startet som et pilotprosjekt i 1995 og ble gradvis landsdekkende frem til 2005. Programmet inviterer alle kvinner i alderen 50-69 år til mammografiscreening hvert annet år. Kreftregisteret har det administrative ansvaret for Mammografiprogrammet, mens screening skjer ved 30 screeningenheter knyttet til 17 spesialiserte brystsentre som har ansvar for diagnostikk, behandling og oppfølging. Mammografiprogrammet støtter seg på kunnskapsbaserte europeiske retningslinjer og anbefalinger. Programmet er stadig gjenstand for debatt, spesielt når det kommer til anslag for reduksjon i brystkreftdødelighet og overdiagnostikk, samt om kvinnene som inviteres tilbys tilstrekkelig informasjon til å ta et informert valg om deltagelse. Mammografiprogrammet har høy oppslutning, om lag 75% av de inviterte møter. Andelen som tilbakekalles etter screening er om lag 3,5%, mens andelen som får diagnostisert brystkreft på bakgrunn av funn på screeningbildene er rundt 0,6% av alle screenede. Målet med Mammografiprogrammet er å redusere dødeligheten av brystkreft gjennom tidlig diagnostikk. Det er også et mål å vedlikeholde og videreutvikle kvaliteten i programmet, og samtidig øke fordelene og redusere ulempene ved deltagelse. Gjennom studier undersøkes blant annet bruken av nye screeningteknikker som tomosyntese, og muligheter innenfor vurdering av mammografibilder med bruk av kunstig intelligens. Programmet ser også fremover med tanke på utvidelse av målgruppen og mer persontilpasset screening. Alle endringer i Mammografiprogrammet vil og bør være basert på tilgjengelig kunnskap og forskning.\u0000Engelsk sammendrag\u0000BreastScreen Norway targets women aged 50 to 69 years for mammography screening every other year. The program started as a pilot project in 1995, was gradually expanded and became nationwide from 2005. Internationally, the history of mammography screening started in the early 1960s, when the first randomized trial in New York began. At that time, breast cancer patients had poor survival. Now, more than 50 years later, organized mammography screening is a highly evaluated and quality assured health care service in Norway and internationally. In Norway, an essential part of building the nationwide screening program was the establishment of specialized breast centers, with a focus on efficient workflow, centralized professional competence, and multidisciplinary teamwork. Another key factor in the program is the invitation system, which is based on personal invitations with scheduled appointments automatically sent to all women in the target group. The invitation system facilitates regular participation regardless of where women live. The Norwegian model for breast screening is based on a centralized database and a shared IT system, which creates distinct opportunities for communication, quality assurance, and research.

The biobank consists of residual blood serum samples from more than 300 000 men and women, who participated in different health surveys in Norway or as Red Cross blood donors during the period 1972–2004. It was established on the initiative of Professor of Pathology, Olav Torgersen (1907–78), referring to the longstanding maxim that ‘prevention is better than cure’. The purpose of the biobank was to build up a resource for studies of cancer aetiology and early detection of cancer, by measuring biochemical and immunological changes several years before the patient’s diagnosis. The Janus cohort, with comprehensive registry-based follow-up, enables longitudinal assessment of the preclinical stage in cancer patients or the latent period before the tumour has been established, and is ideal for the search of novel biomarkers of cancer. The Cancer Registry of Norway took over the cohort in 2004. In 2019 the biobank was moved into new semi-automated storage facilities and all samples were barcoded.\u0000The biobank is annually linked to the Cancer Registry for updates on new cancer cases and by the end of 2020 the number of incident cancer cases in Janus was 107 366.\u0000A continuous work in Janus has been on quality assurance of the biospecimens by investigating sample quality parameters like the effect of different pre-processing of the samples as well as storage time and temperature. We have investigated the stability of various hormones, proteins, metabolites, electrolytes and RNAs. This work has contributed to important knowledge in establishing Good Biobank Practice in Norway. In recent years we have also shown that the trace amounts of DNA in Janus is of sufficient quality for genotyping and methylation studies.\u0000Today Janus is used in a large number of national and international studies and is an active part in several international cancer consortia. The scientific output from the biobank contains a substantial proportion of high impact papers that have contributed to increased knowledge on cancer biomarkers for use in cancer control. Many of the projects have focused on investigating the association between infections and cancer, environmental exposures and cancer and early detection biomarkers. In recent years we have identified RNAs as early detection and potentially screening biomarkers of cancer. We have developed and optimized an RNA sequencing method for samples with low input RNA and produced RNA profiles of pre-clinical samples from 1631 cancer patients and 673 cancer-free controls. The sequencing data is combined with detailed cancer information from the Cancer Registry of Norway and information on environmental exposures from health surveys, in advanced biocomputational analysis.
