Treatment method assignment is depending on the identification of chromosome mixed chromosome 1p/19q LOH. Those sufferers with this favorable prognostic obtaining are allowed to proceed with chemotherapy alone for 1 12 months, whereas these sufferers not exhibiting LOH are taken care of with concurrent chemo radiation and adjuvant chemotherapy. Our key intentions are to demonstrate the security of single agent chemotherapy on this popula tion, to present the noninferiority of this regime when in contrast with published accounts of therapy in this sickness, and also to describe the inci dence of adverse events linked to radiation/chemotherapy in non LOH sufferers. The goal could be to show that single agent chemotherapy can be a rational therapy selection with regard to security inhibitor price and efficacy and ought to be considered as a remedy arm in significant randomized trials. To date, 41 individuals happen to be accrued, 27 with 1p/19q LOH, ten with no LOH, and four pending final results.

A previ ous phase II trial demonstrated the efficacy of intensive PCV fol lowed by myeloablative single agent thiotepa with ASCR. We report the preliminary benefits of the new trial utilizing an intensified myeloablative regimen,

busulfan and thiotepa. Twenty sufferers from 4 institu tions that has a median age of 46 years and a KPS of 90 were treated with four cycles of I PCV. Patients by using a complete response to I PCV or who continued to be free of enhancing disorder after surgery and I PCV were eligible for transplant. Prospec tive testing of 1p/19q LOH was performed. Fourteen individuals had a CR or CCR to I PCV and underwent transplant. Ten of these individuals are alive with no evidence of progression at a median adhere to up of 19 months.
