ABSTRACT
Objective To improve the therapeutic response and survival of locally advanced pancreatic cancer treated with radiochemotherapy. Methods Fifty nine patients with stage Ⅱ Ⅲ pancreatic cancer were divided into two groups: 33 patients were treated with three dimensional conformal radiotherapy (3DCRT) plus regional intra arterial infusion chemotherapy (CT)and 26 patients received 3DCRT alone.Results The response (pain alleviating) rates were 78.8% in 3DCRT+CT group and 80.8% in 3DCRT group,while the overall response (CR+PR) rates were 78.8% and 42.3% (P
ABSTRACT
Purpose: To analyze the treatment effects by radiotherapy alone and radiotherapy plus chemotherapy of carotid artery intubation after operation for malignant astrocytoma. Materials and Methods: 135 patients with malignant astrocytoma were treated from August, 1987 to November, 1992. Patients were divided into two groups after operation: 71 patients received radiotherapy alone and 64 patients,combination therapy of chemotherapy (BCNU) plus radiotherapy. All patients received DT 55～70Gy. In combination therapy group, BCNU(250mg) was given daily by carotid artery intubation for 4～15 days.Radiotherapy was given 10～15 days after chemotherapy, then followed by 1～3 intubation. Results: The median survival were 17.5 months in radiotherapy alone group and 31.9 months in combination one.Patients with glioblastoma gave the better results with the 2-,3-,and 5- year survivals of 70%, 36% and 15%, respectively. Conclusion: Chemotherapy (BCNU) of intubation plus radiotherapy is preferable in treating malignant astrocytoma after operation.
