Methods: Sixty-two patients with cerebral glioma who had residual tumor were divided into 3D-CRT group (radiotherapy group, n=31) and 3D-CRT with concurrent chemotherapy group (chemoradiotherapy group, n=31) prospectively. All patients received a dose of 50-60 Gy/25-30 F/5-6 weeks by 6 MV-X ray, three-dimensional conformal radiotherapy, 1 f/d, 5 times a week. Chemotherapy regimen was Temozolomide:75 mg/m2/d, concomitantly with radiotherapy, followed by 150-200 mg/m2/d, 5 days, 28 days per cycle, totally 3-6 cycles. Results: The total response rate was 35.3% (11/31) in radiotherapy group. The response rate was 61.3% (19/31) in chemoradiotherapy group. There was significant difference in curative effect (P=0.042). There was no significant difference in survival comparison of two groups (P=0.263). Stratified analysis showed the patients with grade Ⅲ gliomas of chemoradiotherapy group had better prognosis than ones of radiotherapy group (P=0.043). Conclusion: The 3D-CRT with concurrent chemotherapy can improve the survival of cerebral gliomas with pathological grade Ⅲ.展开更多

Methods： From May 2005 to May 2009, 36 patients with recurrent cervical cancer were treated by 3D-CRT of 60-66 Gy and TP （docetaxel 70 mg/m^2, d1; cisplatin 20 mg/m^2, dl-d3; 21 days per cycle, totally 2 cycles） concurrent chemotherapy. Results： All of the patients had finished the 3D-CRT, the total response rate, complete response rate and partial response rate were 80.0% （28/35）, 45.7% （16/35）, and 34.3% （12/35）, respectively. The pain-alleviation rate was 91.4% （32/35）. The hemorrhage control rate was 94.3% （33/35）. The median overall survival was 21.2 months. The 1-, 2- and 3-year survival rates were 54.3%, 37.1% and 22.8%, respectively. The life qualities of the patients were improved, without any treatment related death. Conclusion： Radiotherapy is effective and well-tolerated for recurrent cervical cancers, and it can promote regional control of the disease and prolong survival time.展开更多
