| 目的 比较鼻咽癌患者调强放疗与常规放疗的急慢性反应和生存质量。方法 系统分析2008年8月至2010年9月在宁波市李惠利医院行常规放疗及调强放射治疗(IMRT)的初治鼻咽癌患者91例,分为IMRT组(35例)和常规放疗组(56例)。常规放疗采用面颈联合野+颈切线野及耳前野+颈部电子线野,靶区剂量2.0 Gy/次,35次,共70 Gy;调强放疗设定9个共面野,靶区剂量2.12 Gy/次,33次,共69.96 Gy。比较IMRT和常规放疗患者的急性不良反应如口干、吞咽疼痛、吞咽困难、皮肤和黏膜反应等;晚期放射损伤如吞咽困难、张口困难、甲状腺功能低下、视力及听力下降、皮肤损伤、皮下组织纤维化、脊髓炎、脑损伤等方面。结果 与常规组相比,IMRT组的急性不良反应有不同程度的减轻,口干、吞咽疼痛、吞咽困难、皮肤反应和黏膜反应等的发生率较低(χ2=85.73、 56.03、 26.58、69.28和55.99,P<0.05);晚期损伤中口干、吞咽困难、味觉改变、张口困难、皮肤损伤等方面显著减轻(χ2=37.95、7.48、9.49、9.49和11.87, P<0.05),而听力下降程度、视力损伤、脑损伤等的发生率差异无统计学意义,可能与随访时间较短有关。结论 相对于常规放疗,IMRT技术能够减轻急性不良反应,并减少晚期损伤发生率,改善患者的生存质量。 |

| Objective To compare the acute and late adverse events and quality of life (QOL) in patients with nasopharyngeal carcinomas receiving conventional external beam radiation therapy (RT) versus intensity modulated radiation therapy (IMRT). Methods Ninety-one patients with newly diagnosed nasopharyngeal carcinoma treated in our institution between August 2008 and September 2010 were systemically reviewed, including 35 cases administered with conventional RT (RT group) and 56 cases with IMRT (IMRT group). Conjoint facio-cervical fields plus tangential lower neck-supraclavicular field initially, and then shrinking preauricular portals plus electron beams to the neck were adopted in RT groups, with a total dose of 70 Gy/35 fractions. Nine coplanar fields were conducted in IMRT group with a total dose of 69.96 Gy/33 fractions. Acute and late adverse reactions were observed and compared between RT and IMRT groups,including acute reactions as xerostomia, odynophagia, dermatitis/mucositis and late events as dysphagia, trismus, hypothyroidism, optic/acoustic impairments, skin injury, hypodermal fibrosis, spinal myelitis and brain injury. Results Compared with RT group, IMRT group showed less acute reactions in xerostomia, odynophagia, dysphagia and dermatitis and mucositis(χ2=85.73, 56.03, 26.58,69.28,55.99,P<0.05),and less late reactions in xerostomia, dysphagia,trismus,taste loss and skin injury(χ2=37.95, 7.48, 9.49, 9.49, 11.87, P<0.05), whereas the degree of acoustic/optic impairments and brain injury showed no difference in both groups. Conclusions As compared to conventional RT, IMRT could decrease acute and some late side events, and improve the quality of life in patients with nasopharyngeal carcinoma. |
