Prognostic Model of Death and Distant Metastasis for Nasopharyngeal Carcinoma Patients Receiving 3DCRT/IMRT in Nonendemic Area of China.

Few studies were conducted to explore the prognostic factors for nonendemic nasopharyngeal carcinoma (NPC) in the era of 3-dimensional conformal radiation therapy (3DCRT)/intensity-modulated radiation therapy (IMRT). The aim of this study was to evaluate the potential prognostic factors for nonendemic NPC.Between January 2004 and December 2011, a total of 393 nonendemic NPC patients receiving 3DCRT/IMRT were reviewed according to the inclusion and exclusion criteria.

Early radiotherapy has an essential role for improving survival in patients with stage I-II nasal-type of NK/T cell lymphoma treated with L-asparaginase-containing chemotherapy--a single institution experience.

The purpose of this study was to investigate the role of early radiotherapy in patients with localized-stage nasal-type natural killer (NK)/T cell lymphoma treated with L-asparaginase-containing chemotherapy. Sixty-four patients with stage I-II nasal-type NK/T cell lymphoma were enrolled in this study. All patients received an L-asparaginase-containing regimen.

Clinical outcome for nasopharyngeal carcinoma with predominantly WHO II histology treated with intensity-modulated radiation therapy in non-endemic region of China.

Objectives: To evaluate the clinical outcomes of using intensity-modulated radiotherapy (IMRT) in the primary treatment of nasopharyngeal carcinoma (NPC) in Northwest China, including assessments of failure patterns, toxicities and potential prognostic factors.

Methods And Materials: Between January 2006 and June 2010, 193 newly diagnosed non-metastatic NPCs were treated by IMRT with simultaneous-integrated boost (SIB) technique in Xijing Hospital of Northwest China. Cisplatin-based chemotherapy was offered to 85.
