Circulating Tumor DNA Enhances Risk Stratification in Esophageal Cancer

Preoperative circulating tumor DNA (ctDNA) testing can significantly improve risk stratification for patients with early-stage esophageal squamous cell carcinoma (ESCC).

  • CtDNA detected in 48.6% of patients; higher prevalence in t2n0 (57.8%) vs t1b (20%).
  • Positive ctDNA results correlate with worse recurrence-free survival (RFS) and overall survival (OS) — hazard ratios of 4.15 and 4.02, respectively.
  • In t2n0 patients, ctDNA has a 100% positive predictive value for occult nodal metastasis, outperforming standard guidelines.

Integrating ctDNA may refine surgical decision-making and personalize treatment strategies for ESCC patients.

Uniportal esophagectomy linked to fewer pneumonias

In nine comparative studies of minimally invasive esophagectomy for esophageal cancer, uniportal VATS was associated with less pneumonia and a shorter stay than multiportal VATS—but the evidence is not strong enough to establish a preferred approach.
