Efficacy of trastuzumab, carboplatin and docetaxel in human epidermal growth factor receptor‑2 (HER‑2)‑positive breast cancer patients was investigated. A total of 180 HER‑2‑positive breast cancer patients admitted to The First People's Hospital of Yunnan Province were selected, of which 80 patients were treated with carboplatin and docetaxel and served as the control group (CG), and 100 patients were treated with trastuzumab, carboplatin and docetaxel and served as the research group (RG). Clinical efficacy, pathological efficacy, adverse reactions, inflammatory factors interleukin‑6 (IL‑6) and tumor necrosis factor‑α (TNF‑α), cellular immune indexes of T‑lymphocyte subsets (CD4+, CD8+, CD4+/CD8+), and the oxidative stress indexes superoxide dismutase (SOD) and myeloperoxidase (MPO) were observed before and after treatment and were compared between both groups. Patients were followed up for 5 years, and the 5‑year disease‑free survival (DFS), as well as the overall survival (OS) were compared. Clinical efficacy and pathological efficacy in the RG were significantly higher than those in the CG, and the incidence rate of adverse reactions had no significant difference between the two groups. There was no significant difference in inflammatory factors, cellular immune indexes and oxidative stress indexes between the two groups before treatment. After treatment, the levels of IL‑6, TNF‑α, CD8+ and MPO in both groups were significantly reduced and were significantly lower in RG than those in CG. However, the levels of CD4+, CD4+/CD8+ and SOD in both groups were significantly increased after treatment and were significantly higher in RG than those in CG. The 5‑year DFS and OS of the RG were significantly higher than those of the CG. In conclusion, trastuzumab, carboplatin and docetaxel present high efficacy, safety, and 5‑year DFS and OS in HER‑2‑positive breast cancer patients, and have good recovery effect on inflammation, immune response and oxidative stress.
