Adjusted Cox proportional hazards analysis found that age ≥70 years (hazard ratio [HR] 4.60), increasing grade (HR 2.47 for grade 3), progesterone receptor (PR) negativity (HR 1.44), cT3 disease (HR 1.75), and residual macrometastatic nodal disease (HR 1.82 for 1–2 positive nodes; HR 3.37 for ≥3 positive nodes) were associated with increased mortality. This evidence concerns the gene PGR and glycogen storage disease VI.
