ROBUST: A Phase III Study of Lenalidomide Plus R-CHOP Versus Placebo Plus R-CHOP in Previously Untreated Patients With ABC-Type Diffuse Large B-Cell Lymphoma

Patients with the activated B-cell-like (ABC) subtype of diffuse large B-cell lymphoma (DLBCL) historically showed inferior survival with standard rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). Phase II studies demonstrated that adding the immunomodulatory agent lenalidomide to R-CHOP improved outcomes in ABC-type DLBCL. The goal of the global, phase III ROBUST study was to compare lenalidomide plus R-CHOP (R2-CHOP) with placebo/R-CHOP in previously untreated, ABC-type DLBCL

Genome-wide Association Study Identifies Five Susceptibility Loci for Follicular Lymphoma outside the HLA Region

Genome-wide association studies (GWASs) of follicular lymphoma (FL) have previously identified human leukocyte antigen (HLA) gene variants. To identify additional FL susceptibility loci, we conducted a large-scale two-stage GWAS in 4,523 case subjects and 13,344 control subjects of European ancestry. Five non-HLA loci were associated with FL risk: 11q23.3 (rs4938573, p = 5.79 x 10(-20)) near CXCR5; 11q24.3 (rs4937362, p = 6.76 x 10(-11)) near ETS1; 3q28 (rs6444305, p = 1.10 x 10(-10)) in LPP; 18q21.33 (rs17749561, p = 8.28 x 10(-10)) near BCL2; and 8q24.21 (rs13254990, p = 1.06 x 10(-8)) near PVT1. In an analysis of the HLA region, we identified four linked HLA-DR beta 1 multiallelic amino acids at positions 11, 13, 28, and 30 that were associated with FL risk (P-omnibus = 4.20 x 10(-67) to 2.67 x 10(-70)). Additional independent signals included rs17203612 in HLA class II (odds ratio [ORper-allele] = 1.44; p = 4.59 x 10(-16)) and rs3130437 in HLA class I (ORper-allele = 1.23; p = 8.23 x 10(-9)). Our findings further expand the number of loci associated with FL and provide evidence that multiple common variants outside the HLA region make a significant contribution to FL risk

Morbidity and Toxic Effects Associated With Ganciclovir or Foscarnet Therapy in a Randomized Cytomegalovirus Retinitis Trial

BACKGROUND: The Foscarnet-Ganciclovir Cytomegalovirus Retinitis Trial compared the use of either ganciclovir or foscarnet for the initial treatment of cytomegalovirus retinitis in patients with the acquired immunodeficiency syndrome. We previously reported that patients treated with foscarnet lived longer but were more likely to have their treatment switched, the latter suggesting foscarnet may not have been as well tolerated as ganciclovir. This study compared the morbidity and toxic reactions reported during the trial. METHODS: Two hundred thirty-four patients with the acquired immunodeficiency syndrome and previously untreated cytomegalovirus retinitis at 11 university centers were randomly assigned to receive intravenously either foscarnet (n=107) or ganciclovir (n=127). Medical histories, laboratory tests, and drug treatment histories during the first 6 months of treatment were analyzed. RESULTS: Neutropenia was more common in patients assigned to ganciclovir than to foscarnet (34% vs 14%; P=.001). Patients assigned to foscarnet reported more infusion-related symptoms (58% vs 24%; P.001); they also experienced a trend toward more nephrotoxic effects (13% vs 6%; P=.082) and electrolyte abnormalities. The incidence of seizures was similar in both groups (foscarnet, 12%; ganciclovir, 9%; P=.511). Patients assigned to foscarnet were more likely to be switched to the alternative treatment (foscarnet to ganciclovir, 46%; ganciclovir to foscarnet, 11%; P<.001), and most of this excess was attributable to toxic reactions. In 88% of cases in which treatment was switched as a result of toxic reactions and in which follow-up data were available, the toxic reaction resolved after the switch. No permanent disability or death resulted from toxic reactions. CONCLUSIONS: Compared with ganciclovir, the use of foscarnet was more frequently limited by the occurrence of toxic reactions. However, these toxic reactions rarely had long-term sequelae. In light of the previously reported survival benefit seen in patients treated with foscarnet, these data support the use of foscarnet for the initial treatment of cytomegalovirus retinitis.(Arch Intern Med. 1995;155:65-74
