Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Name: Intensity-modulated radiation therapy Type: Radiation
Name: GDP chemotherapy Type: Drug
Overall Status
This study is to evaluate the efficacy and safety of radiotherapy combined with GDP (gemcitabine, cisplatin, dexamethasone) chemotherapy in stage I/II extranodal natural killer/T-cell lymphoma patients with unfavorable prognostic factors.
Detailed Description
Radiotherapy has been recognized as the definitive treatment of choice for stages I and II extranodal NK/T cell lymphoma. The progression-free survival rate and overall survival rate of radiotherapy plus anthracycline-containing chemotherapy were comparable to that of radiotherapy alone. Our previous studies demonstrated the high responsiveness and safety of GDP (gemcitabine, cisplatin, dexamethasone) regimen in patients with extranodal NK/T cell lymphoma. Therefore, we design this study to evaluate the safety and benefit of radiotherapy plus GDP regimen in extranodal NK/T cell lymphoma.
