Abstract   The role of endoscopic resection (ER) in the management of subsets of clinical T1N0 oesophageal adenocarcinoma is controversial. The aim of this study was to evaluate the outcome of ER versus oesophagectomy in node negative cT1a and cT1b oesophageal adenocarcinoma. Methods Data from the National Cancer Database (2010-2015), was used to identify patients with clinical T1aN0 (n = 2,545) and T1bN0 (n = 1,281) oesophageal adenocarcinoma that received either ER (cT1a, n = 1,581; cT1b, n = 335) or oesophagectomy (cT1a, n = 964; cT1b, n = 946). Propensity score matching (PSM) and Cox multivariable analyses were used to account for treatment selection bias. Results ER for cT1a and cT1b disease was performed more commonly over time. The rates of node-positive disease in patients with cT1a and cT1b oesophageal adenocarcinoma were 4% and 15%, respectively. In the matched cohort for cT1a cancers, ER had similar survival to oesophagectomy (HR: 0.85, 95% CI: 0.70-1.04, p = 0.1). The corresponding 5-year survival for ER and oesophagectomy were 70% and 74% (p = 0.1), respectively. For cT1b cancers, there was no statistically significant difference in overall survival between the treatment groups (HR: 0.87, 95% CI: 0.66-1.14, p = 0.3). The corresponding 5-year survival for ER and oesophagectomy were 53% vs. 61% (p = 0.3), respectively. Conclusion This study demonstrates ER has comparable long-term outcomes for clinical T1aN0 and T1bN0 oesophageal adenocarcinoma. However, 15% of patients with cT1b oesophageal cancer were found to have positive nodal disease. Future research should seek to identify the subset of T1b cancers at high risk of nodal metastasis and thus would benefit from oesophagectomy with lymphadenectomy.

Background. Colorectal cancer (CRC) is one of the most common cancers worldwide. Surgical operation is routinely applied to patients with CRC. An important part of postoperative care for patients is to assess the prognosis of patients, especially those with early-stage cancers. However, effective biomarkers for CRC prognosis remain inadequate. The purpose of this study was to assess the prognostic potential of Yes-associated protein (YAP) and carcinoembryonic antigen (CEA) in early-stage CRC. Methods. A total of 116 matched pairs of CRC tissues and adjacent normal mucosae as well as 73 cases of metastatic lymph nodes were analyzed. Results. The results show that CRC tissues exhibited higher YAP expression compared with the adjacent normal mucosae. Immunohistochemical analysis shows that YAP expression in the CRC or lymphatic metastatic tissues was clearly higher than that in normal mucosae (P<0.01), whereas that in CRC tissues with lymphatic metastasis was higher than that in tissues without lymphatic metastasis (P<0.05). YAP expression is associated with serosal invasion, lymphatic metastasis, lymph node ratio, remote metastasis, Dukes stage, and CEA levels (P<0.05). YAP and CEA are independent predictors of the survival of CRC patients (P<0.05 and P<0.01). YAP predicted CRC prognosis primarily for patients with late-clinical-stage CRC (P=0.002), but not for patients with early-clinical-stage CRC (P=0.083). However, patients with high YAP and high CEA levels exhibited lower overall survival rates than those with low YAP expression in early-clinical-stage CRC (P<0.001). Conclusion. High YAP levels in the cancer tissues combined with high plasma CEA levels are potential biomarkers for predicting CRC prognosis in the early clinical stage.
