This retrospective study was conducted to preliminarily explain the effect of different duration of treatment with Chinese patent medicine and Huisheng oral liquid on 2-year survival rate, and to explore prognostic factors affecting 2-year survival rate of patients. Purpose: To compare the effect of different duration of treatment with Chinese patent medicine and Huisheng oral liquid on 2-year survival rate of patients with stage II-III NSCLC, and explore the prognostic factors of 2-year survival rate. Methods: Kaplan-Meier method was used to compare the 2-year survival rate of patients treated with different duration of Chinese medicine and Huisheng oral Liquid. The relationship between different treatment duration and improvement of 2-year survival rate was explored by Cochran-Armitage trend test. Cox proportional hazards regression models were used to explore factors affecting 2-year survival rate of patients. Results: A total of 614 patients with stage II-III NSCLC diagnosed from January 2015 to December 2018 were included in this study.The results showed that: ①The 2-year survival rate of patients treated with Chinese patent medicine for ≥ 3 months and ≥ 6 months was higher than that of patients treated < 3 months. ②The 2-year survival rate of patients treated with Huisheng Oral Liquid for ≥ 3 months was higher than that of patients treated for < 3 months. Cochran-Armitage trend test showed that the 2-year survival rate tended to increase with the duration of Huisheng Oral Liquid treatment. ③ Cox proportional hazards regression model revealed that surgery, chemotherapy and Huisheng Oral Liquid ≥ 3 months were protective factors; Gender was male and FIB ≥ 4g/L were risk factors. Conclusion: Chinese patent medicine and Huisheng oral liquid treatment for ≥ 3 months showed an improvement in 2-year survival rate of patients with stage II-III NSCLC. 2-year survival rate tended to increase with the treatment duration. Finally, the gender was male and FIB ≥ 4g/L were risk factors for prognosis.
