  direct nodal invasion
  Localization
  in pulmonary carcinomas
  in pancreatic carcinomas Isolated direct invasion occurs in 20% of patients with one to two positive nodes. Node involvement by metastasis or by direct invasion are equally significant predictors of reduced survival. doi:10.1007/s11605-009-1096-z. Both the number of positive nodes and the lymph node ratio are significant prognostic factors. doi:10.1007/s11605-009-1096-z. in a 2011 study, direct lymph node invasion has similar (...)
