The multivariate analysis revealed associations between the 3-year OS rates and comorbidities, pN and the Ki-67-positive index (all p < 0.05), and the 3-year RFS rates were associated with pN and the Ki-67-positive index (all p < 0.05); neither OS rates nor RFS rates were associated with sarcopenia in patients with gNEC (Supplemental Table 2). The gene discussed is MKI67; the disease is sarcopenia.
