广州市中山医科大学附属肿瘤医院于1985、1986年分别收治放疗的3644及4033例恶性肿瘤患者中,鼻咽癌分别为2169及2892人。鼻咽癌已占放疗病者总数的59.5％～71.6％。笔者就鼻咽癌放疗问题,浅谈以下三点。一、要更加精细地进行放疗前的诊断诊查鼻咽癌原发病灶累及的范围,过去主要依靠症状、体征、X线片(包括切层、鼻咽腔钡胶浆造影)。由于X线片只能显示鼻咽邻近的明显骨质破坏或巨大软组织侵犯,而大量早期骨破坏和鼻咽旁间隙受累都被遗漏。临床常常只能公式化地设计照射野。结果要不是一些组织受到过度照射,就是侵犯
Of the 3644 and 4033 patients with malignant tumors who received radiotherapy in 1985 and 1986 respectively, 2169 and 2892 were nasopharyngeal carcinomas. Nasopharyngeal carcinoma has accounted for 59.5% to 71.6% of the total number of patients with radiotherapy. The author discusses the following three issues regarding nasopharyngeal carcinoma radiotherapy. First, it is necessary to conduct a more precise diagnosis of radiotherapy before diagnosis of primary nasopharyngeal lesions involved in the area, in the past mainly rely on symptoms, signs, X-ray film (including the cut layer, nasopharyngeal fistula mortar imaging). Since the X-ray film can only show significant bone destruction or large soft tissue invasion near the nasopharynx, a large number of early bone destruction and paranasal pharyngeal space involvement are missing. Clinically, radiation fields can often only be formulated. The result is that if some organizations are exposed to excessive light, they are infringed.
