Malignancy
YES
To determine the oncogenic driver positivity in patients with NSCLC harboring high-VAF FANCD2 variants (VAF>=40%) using institutional tumor-only CGP data, and to exploratorily compare it with those without FANCD2 variants.
Others
To evaluate the driver-positive proportion in the low-VAF FANCD2 group (VAF<40%).
To describe the FANCD2 variants, VAFs, co-occurring driver alterations, and clinicopathologic characteristics of high-VAF FANCD2 cases.
To characterize the concordance or discordance of tumor driver alterations in familial cases, including first-degree relatives sharing the identical FANCD2 variant.
To exploratorily describe the co-occurrence of high-VAF variants and driver oncogenes across other panel-sequenced genes using the same VAF threshold (>=40%).
To perform sensitivity analyses excluding either member of the parent-child pair to account for their biological non-independence.
Exploratory
Not applicable
The proportion of patients harboring oncogenic drivers in the high-VAF FANCD2 group, and comparison with FANCD2-negative patients
Proportion of driver-positive cases in the low-VAF FANCD2 group
Proportion of driver-positive cases in the overall FANCD2-positive group (high- and low-VAF combined)
Details of driver alteration types and FANCD2 variants in high-VAF FANCD2 cases
Characterization of the shared FANCD2 variant and discordant driver fusions in the parent-child pair
Proportion of driver positivity across genes harboring high-VAF variants other than FANCD2
Co-occurrence of high-VAF variants and oncogenic drivers within Fanconi anemia and homologous recombination repair pathway gene
Sensitivity analysis accounting for biological non-independence within the family
Observational
| Not applicable |
| Not applicable |
Male and Female
Patients diagnosed with NSCLC at our institution during the study period.
Patients who underwent CGP using OCA v3 or OCA Plus as part of routine clinical care and whose analysis results are evaluable.
Patients whose minimum required clinical data can be retrieved from medical records.
Patients who underwent CGP exclusively for tumors other than NSCLC.
Patients whose genomic alterations, such as gene mutations or fusions, are substantially uninterpretable due to inadequate specimen quality or other technical reasons.
Patients who declined to participate in the study via opt-out, either by themselves or through their proxies.
Patients deemed inappropriate for analysis by the principal investigator due to compromised data quality (reasons to be documented).
