Summary

Story summary

A study of 1,217 non-small cell lung cancer (NSCLC) patients found 40.4% were aged 60 or older, linking metastasis to age, gender, and smoking history.
The Exon 21-L858R mutation was linked to reduced lymph node metastasis but did not affect distant metastasis.
EGFR mutations were associated with both lymph node and distant metastasis; KRAS and RET mutations had weaker links.
