作者观查了48例鼻咽癌放射治疗效果。治疗方法是对原发灶及转移淋巴结采用~(60)钴远距离放射法,左右相对2野照射。剂量:淋巴上皮癌为50G-y,5次/周,1.9Gy/次。低度未分化癌及分化癌为60Gy。按Kaplan Meier统计方法,5年累积生存率40%,原病生存率47%,原发灶控制率(T控制率)56%,转移淋巴结控制率(N控制率)77%。鼻咽癌Ⅱ+Ⅲ期原病生存率73%,累及生存率56%,而Ⅳ期分别为42%及36%,两组间具有统计学差异(P<0.05)。原发灶的进展程度(T进展程度)和T控制率关系密切,T进展时,T控制率降低,原病生存率低。T进展程度与N控制率间尚无明显相关性。对于N控制率。本组病例经初期
The authors observed 48 radiotherapy effects of nasopharyngeal carcinoma. The treatment method was to use ~(60) cobalt long-distance radiation for the primary tumor and metastatic lymph nodes, and the left and right relative two-field irradiation. Dosage: Lymphatic epithelial carcinoma 50G-y, 5 times/week, 1.9 Gy/time. Low-grade undifferentiated carcinoma and differentiated carcinoma are 60 Gy. According to the Kaplan Meier statistic method, the 5-year cumulative survival rate was 40%, the primary disease survival rate was 47%, the primary tumor control rate (T control rate) was 56%, and the metastatic lymph node control rate (N control rate) was 77%. The survival rate of stage II+III primary nasopharyngeal carcinoma was 73%, and the survival rate was 56%, while stage IV was 42% and 36% respectively. There was a statistical difference between the two groups (P<0.05). The degree of progress of the primary tumor (degree of progression of T) is closely related to the rate of T control. When T progresses, the rate of T control decreases, and the survival rate of the original disease is low. There is no significant correlation between the degree of progression of T and the rate of N control. For N control rate. The initial cases of this group
