Observation on the Therapeutic Effect of Huaier Granules in the Adjuvant Treatment of Non-small Cell Lung Cancer After Radical Surgery

This study is a small sample observational study, mainly exploring whether the 3-year DFS of the Huaier group is not inferior to the control group receiving standard platinum dual drug chemotherapy. Therefore, this study will conduct a small sample exploratory analysis. It is expected to include 240 non-small cell lung cancer patients who have been diagnosed with stage Ⅱ-ⅢA and are eligible for surgery at selected research centers from April 2023 to July 2025. Among them, 120 patients in the Huaier Granule group refused to undergo adjuvant chemotherapy due to reasons such as intolerance or disagreement, and agreed to receive Huaier Granule monotherapy as an adjuvant treatment; There are 120 patients in the control group, all of whom plan to receive standard chemotherapy as an adjuvant treatment plan (including platinum based dual-drug combination chemotherapy).
