Brief Summary:
Targeted next generation sequencing (NGS) provides a promising method for diagnostic purposes by enabling the simultaneous detection of multiple gene mutations. This study is to evaluate the feasibility and application value by using NGS into identifying genomic mutations in multiple or multifocal primary lung cancers in cell-tumor DNA (ctDNA) from surgical patients

Condition or disease
Carcinoma Non-small-cell Lung Cancer Thoracic Neoplasms

Detailed Description:
Tumor samples originating from clinically considered multiple or multifocal primary lung cancer patients were available for mutational analysis. DNA and RNA were extracted from fresh tumor tissue or formalin-fixed, paraffin-embedded (FFPE) tissue. A series of cancer-related genomic alterations including single nucleotide variations (SNVs), short insertions and deletions (InDels), copy number variations (CNVs) and gene rearrangements were identified by Oncomine Comprehensive Panel(OCP). High frequency mutations were also identified in blood sample by droplet digital polymerase chain reaction(ddPCR).

Primary Outcome Measures :
  1. The detection rate of cancer related genes in multiple primary lung cancer patients by targeted next generation sequencing [ Time Frame: 18 months ]

Secondary Outcome Measures :
  1. The concordant and discordant frequency of genomic results between tumor tissue and circulating tumor DNA in multiple primary lung cancer patients [ Time Frame: 18 months ]
  2. The relationship between disease free survival and genomic results in multiple primary lung cancer patients [ Time Frame: 5 years ]
  3. The relationship between overall survival and genomic results in multiple primary lung cancer patients [ Time Frame: 5 years ]

Biospecimen Retention:   Samples With DNA
Fresh tumor tissue, peripheral blood cells, and plasma samples were collected from each patient.
