TL;DR
The use of multiple stage classification systems—UICC/AJCC‐TNM‐system, SEER‐Summary‐Stage, Essential‐TNM (ETNM), and Condensed‐TNM (CTNM) complicates their utility and interoperability, and the lack of a unified framework for translating between their categories limits data harmonization for global epidemiological analyses.
Abstract
Although accurate information on cancer stage at diagnosis is critical for surveillance, cancer registries in low‐ and middle‐income countries (LMICs) report incomplete stage data. The use of multiple stage classification systems—UICC/AJCC‐TNM‐system, SEER‐Summary‐Stage (SSS), Essential‐TNM (ETNM), and Condensed‐TNM (CTNM) complicates their utility and interoperability. The lack of a unified framework for translating between their categories limits data harmonization for global epidemiological analyses.
Population-based cancer registries (PBCRs) systematically and continuously collect data on all cancer cases within defined populations following international standards to ensure harmonization, data quality and complete coverage. They operate on regional or national level and inform us of the burden of cancer in terms...

Take Home Message Costs of non-muscle invasive bladder cancer are highly heterogeneous and strongly influenced by disease severity and early treatment. Real-world, stage-specific estimates are essential for informing cost-effectiveness analyses and guiding health care decision-making.

Molecular pathology has become central to precision oncology, but German cancer registry data structures were designed for simpler molecular findings. This study argues that registries need a minimal, structured, and interoperable representation of molecular variants that remains compatible with data minimization and e...

This structured narrative review examines how biological characteristics, stage at diagnosis, access to multimodality treatment, survivorship services, and health-system capacity interact in low- and middle-income countries (LMICs), with Indonesia developed as a country case study.

Cancer registries are essential for population-level surveillance, epidemiologic research, and public health planning, but their accuracy depends on human review of key variables documented in unstructured clinical text. This is time-consuming, and current quality assurance (QA) typically relies on reviewing fewer than...

Cancer registries are integral to public health infrastructure and support not only the monitoring of cancer incidence and mortality but also cancer control planning, quality assurance of screening programs, evaluation of healthcare delivery, prognostic assessment, and development of research infrastructure.
