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。
The clinical and CT results of 105 NPC cases treated before and after 1986 to 1988 were compared. At the end of radiotherapy, the tumor extinction rate was 72.7% at the end of radiotherapy, and the CT scan extinction rate was 36.4%. After 23 cases of radiation therapy, the tumor regression rate was 60.3% in 1 to 4 months, while the CT tumor regression rate was 34.8%. After 5 to 9 months of radiotherapy in 13 cases, the tumor regression rate was 84.6% in clinical and CT examinations. In radiation therapy, different degrees of radiation reactions can occur in the normal paranasal sinus and nasal cavity. The radiation response of maxillary sinus and sphenoid sinus can be divided into lamella type, crescent type, ring type, and polypoid type. The ethmoid sinus radioresponse is in the ethmoid sinus as a unit, and the weight can also be fused into multiple pieces in a small chamber. Nasal mucosal edema, adhesions.
