“…The guidelines, focusing initially on breast, cervix, colorectal and prostate cancer, have been recently translated to French (available at https://gicr.iarc.fr/) and Turkish, with Arabic translation planned to ensure wider use in the MENA region. In addition, IARC and related partners recently launched CanStaging + , an online tool for TNM staging that is open source and available for use both for clinical and public health community [36] .…”

“…This study highlights countries where stage data are not routinely collected by PBCRs often due to the complexities and additional resources required in collecting these data. Global efforts such as the Global Initiative for Cancer Registry development are key to coordinate actions to improve global coverage of PBCRs, including the availability and comparability of staging information, particularly in LMICs, through specific training sessions, the CanStaging + collaboration, and the Essential TNM classification …”

“…Global efforts such as the Global Initiative for Cancer Registry development are key to coordinate actions to improve global coverage of PBCRs, including the availability and comparability of staging information, particularly in LMICs, through specific training sessions, the CanStaging + collaboration, and the Essential TNM classification. 5,34 Although we focus on describing the proportion of known staged cases in this study, it is important to comment on the distribution of unknown stages and the marked variation we observed. Although European and North American registries reported less than 30% of cases with unknown stages, several countries from Africa and Asia had substantially higher (more than 50%) unknown stages to report.…”

ImportanceStage at diagnosis is a key prognostic factor for cancer survival.ObjectiveTo assess the global distribution of breast cancer stage by country, age group, calendar period, and socioeconomic status using population-based data.Data SourcesA systematic search of MEDLINE and Web of Science databases and registry websites and gray literature was conducted for articles or reports published between January 1, 2000, and June 20, 2022.Study SelectionReports on stage at diagnosis for individuals with primary breast cancer (C50) from a population-based cancer registry were included.Data Extraction and SynthesisStudy characteristics and results of eligible studies were independently extracted by 2 pairs of reviewers (J.D.B.F., A.D.A., A.M., R.S., and F.G.). Stage-specific proportions were extracted and cancer registry data quality and risk of bias were assessed. National pooled estimates were calculated for subnational or annual data sets using a hierarchical rule of the most relevant and high-quality data to avoid duplicates.Main Outcomes and MeasuresThe proportion of women with breast cancer by (TNM Classification of Malignant Tumors or the Surveillance, Epidemiology, and End Results Program [SEER]) stage group.ResultsData were available for 2.4 million women with breast cancer from 81 countries. Globally, the proportion of cases with distant metastatic breast cancer at diagnosis was high in sub-Saharan Africa, ranging from 5.6% to 30.6% and low in North America ranging from 0.0% to 6.0%. The proportion of patients diagnosed with distant metastatic disease decreased over the past 2 decades from around 3.8% to 35.8% (early 2000s) to 3.2% to 11.6% (2015 onwards), yet stabilization or slight increases were also observed. Older age and lower socioeconomic status had the largest proportion of cases diagnosed with distant metastatic stage ranging from 2.0% to 15.7% among the younger to 4.1% to 33.9% among the oldest age group, and from 1.7% to 8.3% in the least disadvantaged groups to 2.8% to 11.4% in the most disadvantaged groups.Conclusions and RelevanceEffective policy and interventions have resulted in decreased proportions of women diagnosed with metastatic breast cancer at diagnosis in high-income countries, yet inequality persists, which needs to be addressed through increased awareness of breast cancer symptoms and early detection. Improving global coverage and quality of population-based cancer registries, including the collection of standardized stage data, is key to monitoring progress.

“…As well as detailing incidence cancer registries consistently stage cancers according to international rules [25] over time, so it will be possible to determine whether the pandemic has caused any stage shifts. An enhanced tool for cancer staging can improve the staging levels [26] .…”
