Gemcitabine treatment in pretreated cutaneous T-cell lymphoma: experience in 44 patients.
PURPOSE: To evaluate the efficacy and toxicity of gemcitabine, a novel pyrimidine antimetabolite with a low-toxicity profile and activity in several solid tumors, in patients with relapsed or refractory cutaneous T-cell lymphomas. PATIENTS AND METHODS: Between May 1997 and February 1999, 44 previously treated patients with mycosis fungoides (MF; n = 30) and peripheral T-cell lymphoma unspecified (PTCLU) with exclusive skin involvement (n = 14) were enrolled onto a two-institution, phase II trial and treated with gemcitabine. This drug was given on days 1, 8, and 15 of a 28-day schedule at a dose of 1,200 mg/m(2) intravenously over 30 minutes for a total of three courses. RESULTS: Of the 44 patients, five (11. 5%) achieved complete responses (CRs), 26 (59%) partial responses (PRs), and the remaining 13 showed no benefit from the treatment. Two of the CRs were histologically confirmed. The CR and PR rates were the same for patients with MF and those with PTCLU, respectively. No difference in terms of overall response rate was observed between relapsed and refractory patients. The median durations of CR and PR were 15 months (range, 6 to 22 months) and 10 months (range, 2 to 15 months), respectively. Treatment was well tolerated; hematologic toxicity was mild, and no nausea/vomiting or organ toxicity was recorded. CONCLUSION: The results of the present phase II study show activity of gemcitabine as a single agent in patients with pretreated cutaneous T-cell lymphoma. Further studies that use gemcitabine alone or in combination with other drugs in earlier stages of the disease are needed.[1]References
