- Beginning CT surveillance earlier after surgery for stage IA NSCLC offers no survival advantage over beginning surveillance later.
Why this matters
- Current guidelines for surveillance after curative NSCLC therapy are inconsistent about the ideal timing and technique.
- 294 patients with stage IA NSCLC underwent R0 resection with no induction or adjuvant therapy.
- Subgroup analysis of 187 patients who underwent CT surveillance at 6±3 months (early CT; n=94) or 12±3 months (late CT; n=93).
- Funding: None.
- In the overall cohort, 49 patients had recurrence and 45 had new NSCLC diagnoses.
- In the subgroup, 21 patients had recurrence and 31 had new NSCLC diagnoses.
- More patients with new NSCLC underwent CT surveillance vs those with recurrence (87% vs 57%; P=.003).
- The late CT group had significantly longer follow-up than the early CT group (56 vs 36 months; P<.01 but the early ct group had more scans vs p=".04).</li">
- No significant difference was seen between groups in incidence of new or recurrent disease, unadjusted 5-year OS, or disease treatment among those with recurrence.
- Retrospective, single-center study.
