Abstract

Furthermore, based on the results of multivariate analysis, we constructed a novel scoring system that included the factors of age, smoking history, alcohol consumption history, number of resected lymph nodes, tumor differentiation, and surgical stage. Risk score (RS) was computed with the scoring system, and patients were divided into Class A (RS: 0–5) and Class B (RS: 6–10). P < 0.001 indicated statistical significance. A significant difference (<italic>p</italic> < 0.001) demonstrated that Class B was strongly related to a low survival rate and poor prognosis.</p> </sec> <sec> <title id="sectitle0030">Conclusion</title> <p id="abspara0025">We developed a new simple flexible scoring system of high prognostic significance, which has the potential to guide postoperative therapeutic strategies and follow-up frequency and to provide better prognostic information for patients and their families.</p> </sec> </abstract>
