Three-dimensional conformal radiation therapy requires the precise definition of the target volume. We aimed to compare the treatment results and radiation toxicities between three-dimensional conformal radiotherapy （3D-CRT） and conventional radiotherapy （CR） for patients with cervical and thoracic esophageal carcinoma. Methods： From June 2004 to December 2006, a random study was performed on 106 patients treated with 3D-CRT or CR, 53 patients in each group. The patients in CR group received conventional radiotherapy in 2.0 Gy/f, 5 f/week and total dose was 66-70 Gy in 6.5 or 7 weeks. The patients in 3D-CRT group were treated by 3D-CRT in 2.0 Gy/f, 5 f/week and total dose was 64-70 Gy in 6 weeks. The local control rates, survival rates and radiation toxicities for the two groups were investigated. Results： The 1-year and 3-year local control rates were 83.0% and 60.4% in 3D-CRT group and 64.2% （x^2 = 4.853, P = 0.028） and 32.1% （x^2 = 9.812, P = 0.002） in CR group. The 1-year and 3-year survival rates were 73.6% and 50.9% in 3D-CRT group and 54.7% （x^2 = 4.102, P = 0.043） and 32.1% （x^2 = 3.886, P = 0.049） in CR group. Between the two groups, there was no significant difference in radiation toxicities. Conclusien： The 1-year and 3-year local control rates and survival rates of patients with esophageal carcinoma treated by 3D-CRT is superior to CR. However, longer-term results and radiation toxicity need further study which involves more patients and prolonged follow-up.展开更多

Two groups of patients were compared, depending on the treatment they have got group, which was taking 75 mg of enteric aspirin per day and the group, where pantoprazole has been added to aspirin in the usual dose. Mucosa assessment was studied using fibrogastroduodenoscopy and Lanza score. Also, the relationship between aggression factors that cause NSAID gastropathy and mucosal protection agents has been studied. It was proved that the pantoprazole influence reduces the ulcerative-erosive lesions amount. Stomach erosive lesions percentage decreased from 58.18% to 42.42%, stomach ulcers from 14.55% to 6.06%, duodenum erosive lesions decreased from 34.55% to 24.24%, duodenum ulcers deceased from 9.09% to 3.03%. A positive correlation between LTB4 and Lanza scale was checked after pantoprazole treatment, indicating an impact on the LTB4 reduction in ulcers healing in patients with NSAID gastropathy.展开更多
