Dexamethasone. cytarabine (ara-C), and cisplatin (DHAP) can be used effectively to treat patients with non-Hodgkin's lymphoma (NHL). We hypothesized that substitution of cisplatin by oxaliplatin (L-OHP) could result in less toxicity and greater efficacy. L-OHP is active in patients with lymphoma. It produces mild myelosuppression and is devoid of renal toxicity. We report on a phase II study of dexamethasone, high-dose ara-C, and L-OHP (DHAOx) used to treat patients with NHL who were previously treated with chemotherapy. Fifteen patients were given DHAOx. They had failed to achieve a CR with initial chemotherapy or had recurrent disease. DHAOx consisted of dexamethasone, 40 mg/day (days 1 to 4): L-OHP, 130 mg/m2 (day 1); and ara-C, 2,000 mg/m2 every 12 h (day 2). Treatment was repeated every 21 days. Patients received a median of four courses of DHAOx. Myelosuppression and transient sensory peripheral neuropathy were the most prominent toxic effects. Serum creatinine levels did not increase in patients with normal renal function, nor in patients who had renal impairment before DHAOx. The median follow-up time from the start of DHAOx treatment was 17 months. Eight patients (53%) achieved a CR, and three patients (20%) had a PR. ...Continue Reading
The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
