Gemcitabine, vinorelbine and prednisone or otehr drugs are being investigated to treat refractory or relapsed aggressive non-Hodgkin lymphomas (NHL).
Lay Summary: Gemcitabine and vinorelbine are somewhat effective but toxic when few options remain, but more investigation is needed.
The optimum therapy for patients with relapsed or refractory aggressive NHL not qualifying for platinum-based and/or high-dose chemotherapy is not known. In one prospective phase II study evaluating a regimen consisting of gemcitabine (1 g/m2, days 1 and 8), vinorelbine (30 mg/m2, days 1 and 8) and prednisone (100 mg/day, days 1-8) (GVP) given every 21 days, there was substantial activity in poor prognosis relapsed or refractory aggressive lymphomas. It was generally well tolerated, but haematological toxicity is dose limiting. Several other studies yilded similar results.
One has to conclude that despite these results the treatment is still experimental as it is being studies in various studies with otehr agents added and a prospective phase III trial is necessary.
