Postoperative Radiotherapy in Pathological T2-3N0M0 Thoracic Esophageal Squamous Cell Carcinoma: Interim Report of a Prospective, Phase III, Randomized Controlled Study.

CONCLUSION: Postoperative radiotherapy significantly increased disease-free survival and decreased local regional recurrence rate in patients with pathological T2-3N0M0 thoracic esophageal squamous cell carcinoma with acceptable toxicities in this interim analysis. Further enrollment and follow-up are warranted to validate these findings in this ongoing trial. IMPLICATIONS FOR PRACTICE: The value of adjuvant radiotherapy for patients with node-negative esophageal cancer is not clear. The interim results of this phase III study indicated that postoperative radiotherapy significantly improved disease-free survival and decreased local-regional recurrence rate in patients with pathological T2-3N0M0 thoracic esophageal squamous cell carcinoma compared with surgery alone with acceptable toxicities. The distant metastasis rates and overall survival rates were not different between the two groups. Adjuvant radiotherapy should be considered for pathologic T2-3N0M0 thoracic esophageal squamous cell carcinoma. Prospective trials to identify high-risk subgroups are needed.

CONCLUSION: A neoadjuvant treatment is clearly recommended for locally advanced esophageal cancer. Currently, chemoradiotherapy according to the CROSS protocol is preferred for squamous cell carcinoma. For adenocarcinoma both chemotherapy according to the FLOT protocol as well as chemoradiotherapy in a neoadjuvant treatment concept lead to an improvement in the prognosis.

This study aimed to evaluate the changes in indoleamine 2,3-dioxygenase 1 (IDO1) expression, programmed cell death-ligand 1 (PD-L1) expression, and CD8+ tumor-infiltrating lymphocyte status after neoadjuvant CRT and prognostic significance in esophageal squamous cell carcinoma (ESCC).

nat S Abstract Despite representing a 1% of diagnosed cancer cases in the USA and up to 5% in eastern Asia and Africa, oesophageal cancer still holds numerous questions concerning the best therapeutic management. For squamous cell carcinoma, while radiochemotherapy has proven itself to be the gold standard as part of the trimodality or alone as a definitive treatment, radiotherapy modalities are still debated especially regarding lymph node irradiation. Involved nodes irradiation was developed with the aim of maintaining clinical outcomes and enhancing quality of life but lacks grade 1 evidence. In this article, w...

Conclusions: Neoadjuvant radiation dose impacts pathological response in terms of pMR in oesophageal cancer patients. No radiation dose-response effect was observed for pCR. Further prospective trials are needed to investigate the dose-response relation in terms of pCR. PMID: 31432736 [PubMed - as supplied by publisher]

Background: Neoadjuvant chemoradiation (CRT) remains controversial in the treatment of the oesophagus or gastro-oesophageal junction (GOJ) carcinomas.Methods: We conducted a meta-analysis to assess the efficacy and safety of Neoadjuvant CRT plus surgery comparing with neoadjuvant CT plus surgery or surgery alone. Feasible studies were searched from electronic databases. The outcomes of survival, R0 resection rate and adverse effects were analyzed. The outcomes were measured with relative risk (RR) and odds ratio(OR).Results: Seventeen records including 4095 patients were included. Neoadjuvant CRT improved 1-,2-,3-and 5-yea...
