Background:
The benefits of neoadjuvant chemoradiation (NCRT) compared to upfront esophagectomy (UE) in esophageal squamous cell carcinoma (ESCC) is controversial. Our purpose was to determine whether clinical stages based on the 8th edition American Joint Committee on Cancer Tumor-Node-Metastasis staging system could guide treatment decision.
Methods:
Data from 2503 patients with clinical stages II and III ESCC diagnosed between 2008 and 2014 were obtained from a nationwide database. Propensity score matching was used to identify well-balanced pairs of patients. Cox proportional hazards regression and log-rank test were used in the survival analysis. The outcomes of patients receiving "NCRT followed by surgery" or "UE" strategies were compared.
Results:
The treatment modality (UE or NCRT) was not a prognostic factor in clinical stage II ESCC (HR: 0.97; p = 0.778). In contrast, the UE group demonstrated a significantly worse outcome compared with the NCRT group in clinical stage III ESCC (HR: 1.39; p < 0.001). After matching, patients who underwent UE for clinical stage II ESCC had median survival/3-year overall survival (OS) rates of 27.8 months/39.2% compared with 32.7 months/49.8% in the NCRT group (p = 0.508). The patients who underwent UE for clinical stage III ESCC had median survival/3-year OS rates of 17.9 months/28.2% in the UE group compared with 24.0 months/41.8% in the NCRT group (p < 0.001).
Conclusions:
Our data suggest that NCRT strategy improved survival compared with UE in clinical stage III ESCC but not in clinical stage II tumors.

The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
