Clinical characteristics and prognosis of primary Waldeyer's ring and lymph node diffuse large B-cell lymphoma in the rituximab era.

This study was to compare the clinical characteristics and prognosis of Waldeyer's ring diffuse large B-cell lymphoma (WR-DLBCL) and lymph node DLBCL (LN-DLBCL) in the rituximab era. Before propensity score-matched (PSM), WR-DLBCL group shows more favorable clinical characteristics than LN-DLBCL group. After PSM, there was no significant difference in the response rate and survivals between them.

A dosimetry study precisely outlining the heart substructure of left breast cancer patients using intensity-modulated radiation therapy.

The purpose of this study was to evaluate the feasibility of delineating the substructure of the heart by using 64-slice spiral CT coronary angiography (CTA) in breast cancer patients who underwent left breast-conserving surgery, and to compare the dosimetric differences between the targets and organs at risk in the prone and supine positions in intensity-modulated radiation therapy (IMRT) planning. From January to December 2011, ten patients who underwent left breast-conserving surgery were enrolled in this study. CTA was performed in both the supine and prone positions during the simulation, and conventional scanning without CTA was performed at the same time.
