Abstract:Objective To investigate the effects of docetaxel combined with carboplatin on immune function, inflammatory response, and quality of life in patients with oral cancer.Methods A total of 102 patients with oral cancer treated at Qinhuangdao Hospital of Beijing University of Chinese Medicine between January 2022 and January 2024 were randomly divided into a control group and an observation group using a random number table, with 51 patients in each group. The control group received paclitaxel plus cisplatin, whereas the observation group received docetaxel plus carboplatin. Each cycle lasted 21 days, and both groups received three cycles. Clinical efficacy; immune function (CD3+, CD4+, and CD8+); inflammatory factors [interleukin-6 (IL-6), C-reactive protein (CRP), and tumor necrosis factor-alpha (TNF-alpha)]; tumor markers; quality of life; and adverse reactions were compared between the groups. Patients were followed for 2 years after treatment, and overall survival (OS) and survival rates were recorded.Results The objective response rate was higher in the observation group than in the control group (P < 0.05). After treatment, CD3+ and CD4+ levels were higher and CD8+ levels were lower in the observation group than in the control group (P < 0.05); in both groups, CD3+ and CD4+ levels were lower and CD8+ levels were higher after treatment than before treatment (P < 0.05). Post-treatment IL-6, TNF-alpha, and CRP levels were lower in the observation group than in the control group, and all three levels were lower after treatment than before treatment in both groups (P < 0.05). Post-treatment carcinoembryonic antigen, carbohydrate antigen 19-9, and squamous cell carcinoma antigen levels were lower in the observation group than in the control group, and all three levels were lower after treatment than before treatment in both groups (P < 0.05). Post-treatment Oral Health Impact Profile and University of Washington Quality of Life scores were higher in the observation group than in the control group and were higher after treatment than before treatment in both groups (P < 0.05). The overall incidence of adverse reactions did not differ significantly between the groups (P > 0.05). At the 2-year follow-up, OS was 21.55 (20.17, 22.93) months in the observation group and 18.45 (16.47, 20.43) months in the control group, and the overall survival rate at each time point was higher in the observation group than in the control group (P < 0.05).Conclusion Docetaxel combined with carboplatin improves immune function, reduces inflammation, and enhances quality of life and survival in patients with oral cancer.
