Desjardins 氏(1933)曾提倡利用各种肿瘤对放射线的不同敏感度,来帮助未经开胸探查的肺恶性肿瘤的鉴别。其后有些作者同意这种作法,也有少数不同意,而主张开胸探查来证实病理后(包括大多数晚期不能切除的肿瘤,而只能切取活检的病例),再决定治疗。从放射治疗的角度,肿瘤可分为三大类,即具有放射线敏感性、感应性及抵抗性者。以鳞状细胞癌(肿瘤消失剂量为2500——5500伦)为感应性者,并以此为临界标准,凡肿瘤消失剂量低于此者,即列为敏感性,高于此者即列为抵抗性者。可以依此将常见的恶性肿瘤排列如下。敏感性肿瘤:尤文氏瘤,肾母细胞瘤(Wilm氏瘤),精原细胞瘤,恶性淋巴瘤(包括淋巴肉癌、网织细胞肉瘤、何杰金氏瘤),未分化癌(包括淋巴上皮癌、肺之雀麦细胞癌等),基底细胞癌。
Desjardins (1933) has advocated the use of different tumor sensitivities to radiation to help identify lung malignancies without open chest exploration. Later, some authors agreed to this practice, and there were a few disagreements, and advocated open-chest exploration to confirm the pathology (including most of the late unresectable tumors, and can only take biopsy cases), and then decided to treat. From the point of view of radiation therapy, tumors can be divided into three major categories, namely those with radiation sensitivity, induction, and resistance. The squamous cell carcinoma (tumor disappearance dose of 2500 - 5500 μm) was used as a sensory marker, and this was used as a critical criterion. If the tumor disappears below this dose, it is listed as sensitive. Resistant. The common malignant tumors can be arranged as follows. Sensitive tumours: Ewing’s neoplasm, Wilms’ tumor, seminoma, malignant lymphoma (including lymphosarcoma, reticulocyte sarcoma, Hodgkin’s neoplasm), and undifferentiated carcinoma (including lymph Epithelial cancer, lung buffalo cell carcinoma, etc.), basal cell carcinoma.
