ClinConnect Summary

This is a long‑term follow‑up study of about 34,000 adults who took part in two large nutrition trials in Linxian, China (1985–1991) that looked at vitamins and minerals to help prevent esophageal and stomach cancers. The follow‑up is observational, meaning researchers will watch what happens over time to see cancer rates and overall deaths after the original trials ended, and to explore how nutrition, genetics, and the environment might relate to cancer and stroke. It’s not testing a new treatment, just gathering information to learn more from people who were in the earlier studies.

If you were part of the original Linxian trials, you may be invited to participate in this follow‑up. Eligible adults are 18 to 100 years old; the study uses non‑random, invitation‑based enrollment. The National Cancer Institute leads the project. Participants might be asked to complete interviews, nutrition surveys, and provide a blood sample for genetic and environmental research related to cancer and stroke. Again, no new medicine or device is being studied. The study is ongoing, with participation and data collection continuing toward an estimated completion in 2026.
