为了明确肺外局限性恶性肿瘤、肺内瘤栓形成、肺内实质性转移的肺巨核细胞是否增加,对40例尸检分4组进行了对照比较分析研究。Ⅰ组10例为正常对照组;Ⅱ组10例为患其它组织器官局限性恶性肿瘤无肺癌转移者;Ⅲ组10例为恶性肿瘤伴肺内动脉瘤栓形成而无实质性肿块者;Ⅳ组10例为恶性肿瘤伴有肺内动 In order to determine whether extrapulmonary localized malignancies, formation of intratumoral tumor emboli, and substantial metastasis of lung megakaryocytes were increased, a comparative study of 40 autopsy groups was conducted. 10 patients in group I were normal controls; 10 patients in group II had localized malignant tumors of other tissues and no lung cancer metastasis; 10 patients in group III were malignant tumors with formation of pulmonary embolus without solid mass; Group IV 10 Cases with malignant tumors and intrapulmonary movements
