Non-small cell lung cancer (NSCLC) treatment traditionally relies on Platinum-based chemotherapy along with targeted therapy and immunotherapy. However, the emergence of drug resistance due to genetic factors and the progression of late-stage metastasis pose significant challenges. In Asian medical practices, the integration of Chinese herbal medicine (CHM) alongside conventional therapy has shown promise in improving treatment efficacy, ensuring safety, and mitigating adverse effects. This study aims to comprehensively summarize the prevalence and efficacy of CHM when combined with platinum-based chemotherapy in managing advanced NSCLC. Our analysis encompasses data from 14 randomized controlled trials involving 1451 patients, of which 739 received combined chemotherapy with CHMs while 712 received chemotherapy alone. Notably, the adjunctive use of traditional CHM demonstrated a marked increase in overall survival rates. Patients with NSCLC who received CHMs in combination with chemotherapy exhibited significantly higher Objective Response Rate (ORR) (RR = 1.37, 95% CI [1.20-1.58], p = .000) and Disease Control Rate (DCR) (RR = 1.13, 95% CI [1.07-1.21], p = .000) compared to those solely undergoing chemotherapy. The Karnofsky Performance Status (KPS) (SMD = 1.47, 95% CI [0.30-2.64], p = 0.014) also indicated substantial improvements in the quality of life assessment, involving a total of 277 cases. The systematic review identified 88 herbs and formulas, classified into two primary categories. The first category involves tonifying qi and nourishing yin, thereby enhancing the body's immune function and boost immune therapy, fortifying its ability to combat pathogens, and inhibiting cancer cell proliferation. Herbs such as Rx. Astragali (Huangqi), Rz. Atractylodis Macrocephalae (Baizhu), Rx. Glehniae (Shashen), and Rx. Ophiopogonis (Maidong) were among the most frequently prescribed CHMs. The second category consists of heat-clearing and toxin-removing medicines, effectively regulating the inflammatory response and infection around tumors while exhibiting potent anti-tumor activity, such as Herba Salviae Chinensis (ShiJianChuan) and Selaginella Doederleinii (ShiShangBai). The evidence derived from the meta-analysis strongly suggests that adjunctive CHM treatment can significantly enhance chemotherapy's effectiveness and improve tumor response. Subsequent research focusing on the development and application of CHM is warranted for the advancement of NSCLC treatment methodologies.
