Effects of rosiglitazone on quality of life and prognosis of patients with early stage glottic laryngeal carcinoma.

Early-stage glottic laryngeal carcinoma refers to Tis-T2 lesions without cervical lymph nodes involvement and distant metastasis. Rosiglitazone facilitates expression of anti-inflammatory substances in the body, protecting immune system and improving patient's treatment efficacy and prognosis. We aimed to clarify the influence of rosiglitazone on prognosis of early-stage glottic laryngeal carcinoma. The control group received low-temperature plasma radiofrequency ablation and the observation group additionally received rosiglitazone; 4 mg, 2 times/day for 6 months. After treatment, the observation group showed reduction in the fundamental frequency perturbation and amplitude perturbation and increase in the harmonic-to-noise ratio relative to the control group. Total effective rate was 80.31% and 77.14% for observation and control groups, respectively (P > 0.05). Peripheral blood immune makers were higher in the observation group. The incidence rates of adverse reactions were lower in the observation group. The median survival time was 33 months in control group and 47 months in observation group (P < 0.05). The five-year survival rate was 77.14% in the observation group and 54.29% in the control group (P < 0.05). Rosiglitazone can prolong the survival of early-stage glottic laryngeal carcinoma patients, improving immune function and reducing adverse reactions during treatment.
