However, empirical evidence linking death literacy to self-management behaviors in gastric cancer patients remains limited.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This study employed a cross-sectional design and used convenience sampling to recruit 501 gastric cancer patients from three tertiary Grade A hospitals in Zhejiang Province between August and September 2025.
