摘要
对1986～1988年治疗的105例鼻咽癌放疗前后做了临床和CT检查结果比较。55例放疗结束时临床检查肿瘤消退率为72.7％,而CT检查消退率为36.4％。23例放疗后1～4个月临床检查肿瘤消退率为60.3％,而CT肿瘤消退率为34.8％。13例放射治疗后5～9个月,临床和CT检查肿瘤消退率均为84.6％。放射治疗中,正常副鼻窦和鼻腔都可发生不同程度放射反应。上颌窦和蝶窦的放射反应可分为片状型、月牙型、环型和息肉型。筛窦放射反应以筛窦小房为单位,重者亦可多个小房融合成片状。鼻腔粘膜水肿,粘连。
Comparison of CT scans before and at the conclusion of radiotherapy in 105 NPC patients showed that the CR frequency in CT scans was 36.4% in contrast to 72.7% by clinical examination. After 1-4 months, they were 34.8% and 60.3% respectively. Radiation reaction to various degrees was observed in the nasal cavity and paranasal sinuses which could be classified into 4 types: plague-like, cresent, ring-like and polypoid. That in the ethmoidal cells could be so confluent as to extend into all the cells. Edema and adhesion were observed in the nasal mucosae.
