Preliminary results on the activity of oxaliplatin (L-OHP) in refractory/recurrent non-Hodgkin's lymphoma patients.
BACKGROUND: Many patients with advanced NHL ultimately relapse and require salvage treatment. Oxaliplatin, a diaminocyclohexane (DACH) platinum, has shown a differential spectrum of cytotoxicity with cisplatin, with activity in primary or secondary cisplatin-resistant solid tumors (colon and ovarian cancer). We report the tolerance/activity of this platinum derivate in previously-treated NHL patients. PATIENTS AND METHODS: From July 1988 to February 1994, 22 patients (11 men, 11 women) with recurrent NHL received single-agent oxaliplatin (100-130 mg/m2 i.v. over two hours with antiemetic premedication, q three weeks). All had been previously treated (median number of prior chemotherapy regimens 2, range 1-7) > or = 1 alkylating agent: 22 patients, anthracyclines: 18 patients, cisplatin: four patients, and radiation: 11 patients. Fourteen patients (63%) had progressive disease as best response to their last chemotherapy, and were considered treatment-refractory. All histologies were centrally reviewed in accord with the R.E.A.L. Classification; they were: eight follicular, five MCL, three diffuse large cell, two MALT, one lymphoplasmocytoid, and three other. RESULTS: A total of 144 cycles were administered for a median number of 6 (range 1-30) per patient. The objective response rate was 40% (95%, CI: 21-64), including one CR ( MCL) and eight PRs (four follicular, two MCL, two MALT). The median response duration was 27 months (range 5-44). Treatment-related toxicity was limited to grade 1-2 nausea/vomiting and reversible grade 1-2 peripheral neuropathy in most of the patients. CONCLUSION: Oxaliplatin is an active agent in relapsed/refractory NHL, including the MCL type. Its safety profile makes this agent a good candidate for the development of combined salvage regimens. Further phase II studies are needed to confirm these preliminary results.[1]References
