安替可胶囊联合放射治疗鼻咽癌的疗效观察

目的：观察安替可胶囊联合放射治疗鼻咽癌的疗效。方法：病理确诊为鼻咽癌并有淋巴结转移的初治患者，治疗组（46例）用安替可胶囊联合放射治疗；对照组（43例）单纯给予常规放射治疗。放射治疗方法、剂量两组相同，应用直线加速器或^60Co治疗，每周5次，每次2Gy，鼻咽癌放射剂量为65－70Gy/6.5-7周，颈淋巴结放射剂量为65－70Gy/6.5-7周。观察两组鼻咽癌及颈淋巴结完全消退所需的放射剂量，鼻咽癌及颈淋巴结的完全消退率及外周血NK细胞、T细胞亚群的变化。结果：两组鼻咽癌完全消退所需的平均放射剂量分别为（41．6±8．9）Gy和（50．7±9．2）Gy(P<0.05)，颈淋巴结完全消退所需的平均放射剂量分别为（47．4±10．3）Gy和（56．2±9．7）Gy(P<0.05)。治疗组NK细胞活性，T3、T4值治疗后较治疗前升高（P＜0．05），对照组T3、T4值治疗后较治疗前降低（P＜0．05）。治疗结束后3个月，临床检查鼻咽癌完全消退率分别为93．5％和88．4％（P＞0．05），颈淋巴结完全消退率分别为87．0％和65．1％（P＜0．05）。两组放疗毒副反应相似（P＞0．05）。结论：安替可胶囊联合放射治疗鼻咽癌有助于提高肿瘤消退速度和完全消退率，对改善鼻咽癌患者机体免疫功能和患者一般状况有一定的作用。

Observation on Effect of Radiotherapy and Antike Capsule Combination Therapy in Treating Nasopharyngeal Cancer Patients

OBJECTIVE: To compare the effect of radiotherapy (RT) combined with Antike capsule (AC) and RT alone in treating nasopharyngeal cancer (NPC) patients. METHODS: Eighty-nine patients with pathologically confirmed NPC (stage II-IV) were randomly divided into two groups: group A (46 cases) were treated with RT, receiving 65-70 Gy/6.5-7 weeks to nasopharynx region and the same dosage to neck region, and AC was given in combination. Group B (43 cases) received the same RT alone. The total dosis of RT for complete remission (CR) of primary nasopharyngeal tumor and neck lymph nodes, the CR rate and the changes of peripheral NK cell, T lymphocyte subsets in the two groups were compared. RESULTS: The total dosis of RT for CR in group A and B were 41.6 +/- 8.9 Gy vs 50.7 +/- 9.2 Gy for primary nasopharyngeal tumor, P < 0.05 and 47.4 +/- 10.3 Gy vs 56.2 +/- 9.7 Gy for neck lymph nodes, P < 0.05. The CR rate of primary nasopharyngeal tumor in group A and B were 93.5% and 88.4% respectively, P < 0.05. The activity of NK cell as well as T3, T4 in peripheral blood increased significantly in the group A after treatment, P < 0.05, while in group B, T3, T4 lowered significantly, P < 0.05. CONCLUSION: RT combined with AC could be helpful in elevating and promoting the remission rate of primary tumor and neck lymph nodes, and AC has some effects in improving the immune function and general condition in NPC patients during RT.
