This research investigates the frequency and survival impact of double primary cancers (DPCs) in non-small cell lung cancer (NSCLC) patients.
Analyzed clinical variables of NSCLC patients diagnosed from 2008 to 2024.
Identified types and timing of double primary cancers (DPCs) relative to NSCLC diagnosis.
Used Cox regression models to assess survival impact, adjusting for various clinical factors.
12.5% of NSCLC patients had double primary cancers (DPC).
DPC diagnosed within 5 years was associated with worse survival outcomes (adjusted HR = 1.180).
DPC occurring after NSCLC diagnosis remained linked with poorer survival (adjusted HR = 1.377).
