Background: Breast cancer is the most common cancer diagnosed worldwide, synchronous bilateral breast cancer accounts for unique entity of the disease, particularly post-operative radiotherapy for Synchronous Bilateral Breast Cancer (SBBC) is challenging with lack of evidence about the best irradiation technique. In this study, we tried to explore the optimum radiotherapy technique regarding the dosimetric parameters. Methods: We recruited 15 SBBC patients in whom post-operative radiotherapy was indicated and we established three plans for each patient using 3DCRT, IMRT and VMAT, and then we compared the three plans as regard target volume coverage parameters and organs at risk (OAR) doses. Results: We found that PTV coverage parameter was superior with IMRT compared with 3DCRT and VMAT in terms of Dmean (p = 0.001), D95% (p = 0.001), Dmax (p = 0.0001), conformity index (p = 0.0001) and HI (p = 0.0001). Doses to OAR were not significantly different between the three techniques in m.ly:

A field experim.nt was carried out at Ism.ilia Research Station, Ism.ilia Governorate from.2020-2022 to im.rove the growth of Khaya senegalensis and Swietenia m.hagoni by using a com.ination of m.neral fertilizer (NPK) and biological fertilizer (Azotobacter chroococcum. Bacillus m.gatherium. and Bacillus circulant) as recom.ended dose under new sandy soils conditions. Split plot designed with four treatm.nts (Control, (50% m.neral fertilizer (m.) + 50% Biological fertilizer (Bio.)), 100% m. and 100% Bio.) of each species. Vegetative growth, leaf area, tree biom.ss, stored carbon, basal area, tree volum., and in the soil both of m.crobial account and m.neral content were determ.ned. The experim.ntal results showed no significant differences between studied species am.ng the m.st studied param.ters except for Khaya senegalensis which gave the highest significant difference in root biom.ss and below-stored carbon than Swietenia m.hagoni. Evidently, the highest significant growth param.ters were 100% m.neral fertilizer followed by (50% m. + 50% Bio.) as com.ared with control. No significant difference between 100% m. and (50% m. + 50% Bio.) of shoot dry biom.ss (15.19 and 12.02 kg, respectively) and above-stored carbon (0.28 and 0.22 m., respectively). m.crobial account and m.neral content in soil were im.roved after cultivation of tree species com.ared to before planting and control, especially with 50% m.neral fertilizer and 50% bio-fertilizer treatm.nt. In conclusion, a treatm.nt containing 50% m.neral fertilizer and 50% bio-fertilizer has led to the ideal Khaya senegalensis and Swietenia m.hagoni growth in sandy soil for cheaper and sustainable.
