Abstract Introduction Previous studies evaluating the association of LN yield and survival presented conflicting results and many may be influenced by confounding and stage migration. This study aimed to evaluate whether the quality indicator ‘retrieval of at least 15 lymph nodes (LNs)’ is associated with better long-term survival and more accurate pathological staging in patients with esophageal cancer treated with neoadjuvant chemoradiotherapy and resection. Methods Data of esophageal cancer patients who underwent neoadjuvant chemoradiotherapy and surgery between 2011-2016 was retrieved from the Dutch Upper Gastrointestinal Cancer Audit. Patients with <15 LNs and ≥15 LNs were compared after propensity score matching based on patient and tumor characteristics. The primary endpoint was 3-year survival. To evaluate the effect of LN yield on the accuracy of pathological staging, pathological N-stage was evaluated and 3-year survival was analyzed in a subgroup of patients node-negative disease. Results In 2260 of 3281 patients (67%) ≥15 LNs were retrieved. In total, 992 patients with ≥15 LNs were matched to 992 patients with <15 LNs. The 3-year survival did not differ between the two groups (57% versus 54%, p=0.28). pN+ was scored in 41% of patients with ≥15 LNs versus 35% of patients with <15 LNs. For node-negative patients, the 3-year survival was significantly better for patients with ≥15 LNs (69% versus 61%, p=0.01). Conclusions In this propensity score matched cohort, 3-year survival was comparable for patients with ≥15 LNs, although increasing nodal yield was associated with more accurate staging. In node-negative patients, 3-year survival was higher for patients with ≥15 LNs.

Abstract Background Lynch syndrome (LS) is the most common hereditary colorectal cancer (CRC) syndrome. Comparison of prognosis between LS and sporadic CRC (SCRC) were rare,with conflicting results. This study aimed to compare the long-term outcomes between patients with LS and SCRC. Methods Between June 2008 and September 2018, a total of 47 patients were diagnosed with LS by genetic testing at Fudan University Shanghai Cancer Center. A 1:2 propensity score matching was performed to obtain homogeneous cohorts from SCRC group. Thereafter, 94 SCRC patients were enrolled as control group. The long-term survival rates between the two groups were compared, and the prognostic factors were also analyzed. Results The 5-year OS rate of LS group was 97.6%, which was significantly higher than of 82.6% for SCRC group (p = 0.029). The 5-year PFS rate showed no significant differences between the two groups (78.0% for LS group vs. 70.6% for SCRC patients; p = 0.262). The 5-year TFS rates in LS group was 62.1% for LS patients, which were significantly lower than of 70.6% for SCRC group (p = 0.039). By multivariate analysis, we found that tumor progression of primary CRC and TNM staging were independent risk factors for OS. Conclusion LS patients have better long-term survival prognosis than SCRC patients. Strict regular follow-up monitoring, detection at earlier tumor stages, and effective treatment are key to ensuring better long-term prognosis.
