Clinical Analysis 102 Cases Of Malignant Tumors Complicated With Superior Vena Caval Syndrome

Objective: To explore the better treatment method for malignant tumor complicated with superior vena cava syndrome (SVCS). Methods: The treatment methods of 102 patients were retrospectively analyzed by dividing them into two groups: 57 cases, including 40 lung cancer and 4 malignant thymomas and 13 non-Hodgkin's lymphomas (NHL), were given chemotherapy, 45 patients of them, including 32 lung cancer and 4 malignant thymomas and 9 non-Hodgkin's lymphomas (NHL), were given radiotherapy, the patients of small cell lung cancer were treated with EP regimens, the cases of non-small cell lung cancer were treated with NP regimens, the non-Hodgkin's iymphomas (NHL) patients were treated with CHOP regimens, and the malignant thymomas patients were treated with PAC/EP regimens. The methods of radiotherapy included high-dose radiation for three or four days then followed by normal-dose radiation. Results: The complete relief rate in radiotherapy was 93.3%, significantly higher than that of the chemotherapy (78.9%) (P<0.05). The relief rate in the third day of the group with radiotherapy was significantly higher than that of the group with chemotherapy. But the relief rate in 21th day of both groups shows no apparent difference. The objective relief rates were 90.0% in non-small cell lung cancer, 95.5% in small cell lung cancer, 100% in malignant thymomas, 88.9% in NHL by the radiotherapy. The objective relief rates were 60.0% in non-small cell...
