- چکیده:
- چکیده انگلیسی: In this paper, we obtained the 1-soliton solutions of the symmetric regularized long wave (SRLW) equation and the (3+1)-dimensional shallow water wave equations. Solitary wave ansatz method is used to carry out the integration of the equations and obtain topological soliton solutions The physical parameters in the soliton solutions are obtained as functions of the dependent coefficients. Note that, this method is always useful and desirable to construct exact solutions especially soliton-type envelope for the understanding of most nonlinear physical phenomena.

- چکیده:
- چکیده انگلیسی: Introduction: Previous studies comparing tomotherapy (TOMO) and three dimensional (3D) conformal radiotherapy
(3DCRT) in gastric radiotherapy are limited and tend to be based on dosimetry. The aim of the present study was to
evaluate the clinical outcomes of these two treatment modalities. Methods: A total of 51 patients diagnosed with gastric
cancer who were treated with postoperative adjuvant chemoradiotherapy and had subtotal/total gastrectomy and D2
lymphatic dissection were recruited to the present study: 30 patients were treated with TOMO and 21 patients were
treated with 3DCRT. Results: The 3DCRT and TOMO treatment regimens were compared. There was no difference in
planning target volume (PTV) 95%, but TOMO was statistically significant in regard to PTV 105% (P<0.05). TOMO
was also significantly different when compared with 3DCRT when evaluating liver mean dose, liver V40, right/left
kidneys mean dose, right/left kidneys V20 and spinal cord mean dose values (P<0.05). Grade 2 acute side effects were
more frequent (85.7%) following 3DCRT. In addition, the median overall survival time for TOMO treated patients
was 62 months while in 3DCRT treated patients it was 22.05 months. The difference in disease free survival was also
significantly increased in patients treated with TOMO (66.7% vs. 19.0%; P<0.05). Conclusion: TOMO treatment
resulted in lower acute side effects with better patient survival following gastric cancer radiotherapy.- انتشار مقاله: 03-06-1397
