摘要 目的观察鼻咽癌病人调强放疗和常规放疗的口腔反应。方法62例鼻咽癌病人分为调强放疗组30例和常规放疗组32例。常规放疗采用面颈联合野+下颈前切野放疗,缩野后改用面颈缩野及上颈部电子线放疗,放疗量:鼻咽部DT70 Gy/2 Gy/35 F,颈部治疗量DT70 Gy,预防量DT50 Gy^60 Gy;调强放疗组鼻咽及上颈部采用全程IMRT技术照射,下颈部和锁骨上靶区采用颈前切野常规技术照射,治疗剂量95%PTV/60 Gy/2 Gy/30 F,95%GTV/70 Gy/2.12 Gy/33 F,腮腺受量V50%<35 Gy,下颈前切野放疗至DT50 Gy^60 Gy。结果调强放疗组的口干反应多为1级、2级,口腔黏膜反应多为1级、2级,无3级反应,而放疗组的口干反应多为2级、3级,口腔黏膜反应为2级、3级。调强放疗组的口干、黏膜反应明显轻于放疗组(P<0.05)。结论调强放疗可明显减轻鼻咽癌病人放疗的口干及口腔黏膜反应,改善病人的生活质量。
