[Chemotherapy using gemcitabine hydrochloride for malignant lymphoma]

This report summarizes the use of gemcitabine for the treatment of malignant lymphoma. Gemcitabine is a deoxycytidine antagonist that has characteristics different from those of the deoxycytidine antagonist cytarabine(Ara-C). International guidelines based on the results of recent clinical studies recommend the use of gemcitabine as monotherapy and in combination therapy, particularly for relapsed and refractory malignant lymphomas. Clinical studies on gemcitabine monotherapy up to 2012 reported response rates of 51-75% for peripheral T -cell lymphoma and cutaneous T-cell lymphoma. Regarding combination therapy, the GDP regimen consisting of gemcitabine, dexamethasone, and cisplatin was associated with response rates of 62-70% for relapsed or refractory Hodgkin lymphoma and 45-53% for relapsed or refractory non-Hodgkin lymphoma, thereby displaying comparable efficacy to existing salvage chemotherapy regimens. The GDP regimen has a favorable safety profile and is also associated with favorable autologous transplantation rates, which suggests its potential as induction chemotherapy before autologous transplantation. Concerning adverse reactions requiring clinical caution, lung disorder was reported in 8 of 27 patients(30%)who received a regimen of gemcitabine in combination with bleomycin.
