RESUMO
Objective To investigate the clinical effect of lentinan and thymopentin injection combined with PTP chemotherapy in oral squamous cell carcinoma patients, and to observe the effect of lentinan on serum tumor specific growth factor ( TSGF) , IgG, IgA and IgM and quality of life in patients with oral squamous cell carcinoma .Methods The clinical data of 80 cases of oral squamous cell carcinoma ( postoperative lymph node metastasis) confirmed by operation and pathology were analyzed retrospectively, and the diagnosis and treatment were analyzed.The control group were treated with PTP regimen, 80 ~120 mg/m2 of cisplatin, 50 ~80 mg/m2 of teniposide on the first day, the second to fourth day, once daily +pingyangmycin 4~6 mg/m2 , once daily, 3 to 12 days, 3 weeks for a course of treatment, a total of 6 courses.In the control group based on the use of thymopentin injection 20 mg and lentinan 2 mg+5% glucose solution 250 mL intravenous infusion, chemotherapy 2 d before the start, infusion 14 d, 3 weeks for a course of treatment, a total of 6 courses, for the observation group;two groups were 40 cases.The levels of serum TSGF, IgA, IgG, IgM and CD3 +, CD4 +, CD8 +, NK cells and TSGF in the two groups before and after treatment were measured.The quality of life of the patients was investigated by hospital-made questionnaires.The clinical efficacy and side effects were analyzed.Results TSGF levels in the two groups were significantly lower than that before treatment, and the TSGF level in the observation group was (39.1 ±4.9)U/mL, which was significantly lower than that in the control group (52.3 ±5.8) U/mL(P<0.05).After treatment, the TSGF level in observation group was lower than that in control group [(39.1 ±4.9) U/mL vs. (52.3 ±5.8) U/mL](P<0.05).The CD3 +, CD4 +, NK, IgG levels in observation group were higher than those in control group and the CD8 +level in observation group was lower than that in control group (P<0.05).The scores of physical symptoms, sleep quality, mental state and social affection levels in observation group were higher than those in control group(P<0.05).The total efficacy in observation group was lower than that in control group (77.5% vs.45.0%, P<0.05).The adverse reaction rate was 20.0% in the observation group, which was significantly lower than that in the control group (P<0.05).Conclusion The use of lentinan and thymopentin injection combined with PTP chemotherapy in the treatment of oral squamous cell carcinoma has higher clinical efficacy and less adverse reactions.
