30Gy Versus 40Gy Involved-field Radiotherapy for Localized Diffuse Large B Cell Lymphoma Achieving CR After Chemotherapy

2014-07-23 21:08:33 | BioPortfolio

Summary

The purpose of this study is to determine whether 30Gy Involved-field Radiotherapy (IFRT) is as effective as 40Gy in the treatment of localized Diffused Large B cell Lymphoma (DLBCL) when completing CR after chemotherapy.

Description

The best proper doses of IFRT in combined modality treatments (CMT) for localized DLBCL is still undetermined. Existing treatment guidelines recommend 40Gy or above as the standard treatment dosage. However, there were large-scaled clinical trials implying smaller doses such as 30Gy may be equivalent effective. Lowering radiation doses can decrease treatment toxicities and radiotherapy-induced diseases, which has been conformed by HD13 study for Hodgkin's Lymphoma. It may even retain the truth when modern era radiation techniques are involved and especially in patients achieving CR after chemotherapy. A comprehensive, prospective dose-comparing study is needed.
