Technique for external beam treatment for mesothelioma.

摘要: Abstract A combined photon-electron beam treatment for diffuse pleural mesothelioma is discussed in this paper. The technique consists of parallel opposed 10 MV X rays prescribed to 4250 cGy using customized blocks shield the lung. pleura then boosted with electrons a dose 3600 cGy. combination yields TDF 74 ret pleura. As an earlier paper, method when subtotal pleurectomy and I-125 implantation leads improved survivals minimal complications. details 3-dimensional radiation were not described detail. To improve target coverage local control, has been modified. CT now used along simulation plane films define entire surface. volume also extended from dome base diaphragm. These changes have led distributions; by blocking liver or stomach, boosting crus diaphragm electrons, there little added morbidity. demonstrated histograms, we able deliver 10% most ; lung parenchyma receiving less than 2100
