In Portugal, it remains highly lethal, with 1740 new cases and 1611 deaths estimated in 2022. Hepatocellular carcinoma (HCC) is the main histological type and exhibits variation in risk factors and outcomes. Unlike many malignancies, HCC arises predominantly in chronically diseased tissues and is largely attributable to four modifiable etiologies: hepatitis B (HBV) and C viruses (HCV), alcohol-associated liver disease (ALD), and metabolic dysfunction-associated steatotic liver disease (MASLD).

However, no previous study has examined incidence and mortality across all GI cancer sites within a population, stratified by sex, ethnicity, and socioeconomic status. This retrospective, population-based study aimed to address this gap by providing a comprehensive overview of GI cancer incidence and mortality in New Zealand (NZ) from 2009 to 2019 and examining patterns across demographic subgroups. GI cancer cases (ICD-10-AM C15–C26) were identified from the NZ Cancer Registry and linked to the Mortality Collection to assess mortality. Baseline demographics were summarised, and age-standardised incidence and GI cancer-specific mortality rates were calculated. A total of 57,707 GI cancers were diagnosed in 55,611 individuals. The mean age at diagnosis and death were 69.9 (SD: 13.4) and 73.9 (SD: 12.9), respectively. Of those diagnosed with GI cancer, 54.4 % were male. Incidence trends varied by cancer site: small intestinal cancer increased annually (3 % in males, 4 % in females), while stomach and colorectal cancer incidence declined modestly for both sexes. GI cancer mortality declined significantly across all sites (males: RR=0.92;95 %CI:0.88,0.96;p = 0.002); females: RR= 0.91;95 %CI:0.87,0.96; p = 0.002). Māori and Pacific peoples had the highest incidence and mortality rates for stomach (incidence: 13.2 and 14.2; mortality: 9.3 and 7.1 per 100,000) and liver/biliary tract cancers (incidence: 14.1 and 18.1; mortality: 12.0 and 13.9 per 100,000). A clear socioeconomic gradient was observed, with higher incidence and mortality in the most deprived areas. This study reveals clear disparities in GI cancer incidence and mortality across sex, ethnic, and socioeconomic groups in NZ. These patterns highlight the importance of tailoring cancer prevention and early detection efforts to ensure they reach the communities most affected. A stronger focus on equity is needed, not just in NZ, but also in other settings where similar gaps in cancer outcomes persist.</div></div>","PeriodicalId":56322,"journal":{"name":"Cancer Epidemiology","volume":"100 ","pages":"Article 102973"},"PeriodicalIF":2.3,"publicationDate":"2025-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145684973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Overall and recurrence-free five-year survival from surgery was 88.7 % and 77.4 %, respectively. Two-year overall survival after recurrence was 63.9 %. 135 (82.8 %) of the 163 patients who self-reported recurrence in a national patient experience survey, and 1412 (95.2 %) of the 1483 patients with reported recurrence/progression in Cancer Registry data had recurrence defined by the developed indicator.</div></div><div><h3>Conclusions</h3><div>The validity of the CRC recurrence indicator was supported by observed associations with tumour characteristics, self-reported recurrence, and poor overall survival in patients with recurrence. This indicator can be used in research and service evaluation, to overcome the problem of incomplete cancer recurrence recording in most national cancer registries.</div></div>","PeriodicalId":56322,"journal":{"name":"Cancer Epidemiology","volume":"100 ","pages":"Article 102962"},"PeriodicalIF":2.3,"publicationDate":"2025-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145571963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
