Elevated Serum Vitamin B12 Concentrations Are Nonlinearly Associated with Cancer Incidence and All-Cause Mortality: A retrospective analysis of the global multi-institutional cohort study.

BACKGROUND Serum vitamin B12 is among the most frequently ordered laboratory tests, and both low and high concentrations have been linked to cancer and mortality. However, the full dose-response shape and the contribution of reverse causation remain unclear. OBJECTIVE We aimed to characterize the dose-response shape...

The Childhood Cancer and Leukemia International Consortium (CLIC): Expanding Global Collaboration in Pediatric Cancer Etiology Research

Childhood cancers are rare, but incidence has risen modestly in countries with robust registration, partly reflecting improved diagnosis. In high-income countries, cancer is the leading cause of disease-related death in children. Marked inequities in incidence, survival, and research capacity underscore the need for la...

Association of Low Serum Vitamin B12 Concentration with Colorectal Cancer Risk and All-Cause Mortality: A Global Multi-Institutional Retrospective Cohort Study.

Low serum vitamin B12 was associated with higher all-cause mortality; its association with CRC was less robust at longer landmarks; the CRC finding requires prospective confirmation with serial B12 measurements.
