[The metastatic pattern of malignant tumors].

Four hundred autopsy cases of malignant tumors were analysed. Of these 321 cases (80.3%) had carcinoma and 79 (19.7%) sarcoma. In the 79 cases, 65 had malignant lymphoma, and 14 (3.5%) soft tissue and bone tumor. The tumor cells metastatic to the lung and liver were common in the autopsy cases. There were 163 cases of metastatic tumors in the lung and liver respectively (40.5%). The metastatic tumor in the liver was mainly from the breast, large intestinal, ovary, stomach and NHL, and in the lung mainly from the breast, liver, NHL, stomach and ovary. The lymph node metastasis was mainly located in the neck, mediastina, aorta. The extensive metastatic tumors were lung cancer, gastric cancer, breast cancer and NHL, However, carcinoma in uterus cervix, urinary bladder, pharynex and testis was mainly infiltrated in the original region. The tumor metastasis was related to the region, histologic type and differentiation and so on.
