ABSTRACT
OBJECTIVE:
We aimed to investigate the optimal cutoff value of circumferential resection margin (CRM) of esophageal squamous cell carcinoma (ESCC) in patients who underwent radical esophagectomy.BACKGROUND:
Tumor involvement of a CRM in ESCC has not been clearly defined.METHODS:
We reviewed 479 pT3 ESCC patients to find the optimal cutoff point of distance from CRM in addition to 0âµm for discriminating survival time.RESULTS:
The partitions at and near the 500âµm distance from CRM generated the largest log-rank statistics (Pâ=â0.0086). Therefore, we added 500âµm as an additional cutoff value for a positive CRM. Compared to patients with CRM greater than 500âµm, patients with CRM 0âµm showed worse overall survival (Pâ<â0.001) and progression-free survival (Pâ<â0.001), followed by patients with 0 to 500âµm (Pâ=â0.008 and 0.066, respectively). In multivariable analyses, overall survival differences remained significant [0â<âCRM ≤ 500âµm vs CRM > 500âµm, hazards ratio (HR)â=â1.875, 97.5% CI 1.243-2.829, Pâ=â0.002; CRMâ=â0âµm vs CRM > 500âµm, HRâ=â2.666, 97.5% CI 1.745-4.076, Pâ<â0.001]. In comparison of criteria from the College of American Pathologists, the Royal College of Pathologists, and this study, HRs of positive CRM (95% CI, P-value) were 1.969 (1.501-2.584, Pâ<â0.001), 1.384 (1.039-1.844, Pâ=â0.027), and 1.696 (1.342-2.143, Pâ<â0.001), respectively.CONCLUSIONS:
In patients with ESCC, we developed new, 3-tiered CRM criteria providing more detailed prognostic information than the 2-tiered criteria.
