Randomized Phase II Study of R-CHOP With or Without Bortezomib in Previously Untreated Patients With Non-Germinal Center B-Cell-Like Diffuse Large B-Cell Lymphoma.

Purpose To evaluate the impact of the addition of bortezomib to rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) on outcomes in previously untreated patients with non-germinal center B-cell-like (non-GCB) diffuse large B-cell lymphoma (DLBCL). Patients and Methods After real-time determination of non-GCB DLBCL using the Hans immunohistochemistry algorithm, 206 patients were randomly assigned (1:1; stratified by International Prognostic Index [IPI] score) to six 21-day cycles of standard R-CHOP alone or R-CHOP plus bortezomib 1.3 mg/m intravenously on days 1 and 4 (VR-CHOP).

Relation between chelation and clinical outcomes in lower-risk patients with myelodysplastic syndromes: Registry analysis at 5 years.

Prospective data are needed to ascertain the impact of iron chelation therapy in patients with myelodysplastic syndromes. The present 5-year prospective registry analysis was conducted to compare clinical outcomes between chelated and nonchelated patients with lower-risk myelodysplastic syndromes and transfusional iron overload. In an interim analysis at 24 months, we previously reported that chelation therapy was associated with longer median overall survival and a tendency toward longer leukemia-free survival and fewer cardiac events.

The Effectiveness of Tyrosine Kinase Inhibitors and Molecular Monitoring Patterns in Newly Diagnosed Patients With Chronic Myeloid Leukemia in the Community Setting.

Background: Clinical outcomes of patients with chronic myeloid leukemia (CML) treated in clinical trials, including response to therapy, may not be representative of those treated in a community setting. Thus, we sought to determine the real-world effectiveness of first-line tyrosine kinase inhibitors in CML by evaluating response rates, all-cause discontinuation, and adherence. Response monitoring patterns were also analyzed.

Comparison of 24-month outcomes in chelated and non-chelated lower-risk patients with myelodysplastic syndromes in a prospective registry.

This 5-year, prospective registry enrolled 600 lower-risk MDS patients (pts) with transfusional iron overload. Clinical outcomes were compared between chelated and nonchelated pts. At baseline, cardiovascular comorbidities were more common in non-chelated pts, and MDS therapy was more common in chelated pts.

A Phase III trial of fludarabine, cyclophosphamide, and rituximab vs. pentostatin, cyclophosphamide, and rituximab in B-cell chronic lymphocytic leukemia.

Background: Uncontrolled studies comparing pentostatin (P), cyclophosphamide (C), and rituximab (R) (PCR) to fludarabine plus C+R (FCR) suggest similar efficacy with fewer infectious complications with PCR. We compared FCR and PCR in previously-untreated or minimally-treated B-cell chronic lymphocytic leukemia (CLL).

Treatment: FCR (F 20 mg/m(2) Days 1-5, C 600 mg/m(2) Day 1, R 375 mg/m(2) Day 1) (28-day cycles) or PCR (P 4 mg/m(2) Day 1, C 600 mg/m(2) Day 1, R 375 mg/m(2) Day 1) (21-day cycles).

Results of a phase 2 study of bortezomib in patients with relapsed or refractory indolent lymphoma.

This study evaluated the efficacy and safety of single-agent bortezomib in indolent B-cell lymphoma that had relapsed from or was refractory to rituximab. Sixty patients enrolled: 59 were treated with bortezomib 1.3 mg/m(2) on days 1, 4, 8, and 11 for up to eight 21-day cycles; responders could receive 4 additional cycles; maintenance was optional.

Purine analogue combinations for indolent lymphomas.

Indolent lymphomas are a group of lymphoid malignancies with differing patterns of behavior and responses to treatment. The progress in treating patients with hairy cell leukemia (HCL) using nucleoside analogues can be used as a model for other indolent B-lymphoproliferative disorders, such as follicular lymphoma. Recent advancements in therapeutic options available for these patients include combination therapy with agents that have differing mechanisms of action and non-overlapping toxicity.

Efficacy and safety of liposomal anthracyclines in phase I/II clinical trials.

Preclinical studies have established the pharmacologic advantages of liposomal anthracyclines, including pharmacokinetic profiles after bolus dosing that resemble continuous infusion of conventional anthracyclines, increased drug concentrations in tumor cells compared with the surrounding tissues, and reduced toxicity relative to conventional anthracycline treatment. Based on these studies, many phase I and phase II clinical trials were conducted to assess the safety and potential activity of liposomal anthracyclines in the management of both solid and hematologic tumors. These studies provided valuable insight into the safety of pegylated liposomal doxorubicin (Doxil/Caelyx [PLD]), nonpegylated liposomal doxorubicin (Myocet [NPLD]), and liposomal daunorubicin (DaunoXome [DNX]) over a range of doses, either as single-agent therapy or in combination with other cytotoxic agents.

An open-label pilot study of pentostatin, mitoxantrone, and rituximab in patients with previously untreated, Stage III or IV, low-grade non-Hodgkin lymphoma.

Background: In a previous study, the authors demonstrated that the combination of pentostatin (P) and rituximab (R) was well tolerated and was active in patients with low-grade non-Hodgkin lymphoma (NHL). In the current study, mitoxantrone (M) was added to P + R to evaluate the toxicity and efficacy of this three-drug combination (PMR).

Methods: Twenty-four previously untreated patients with histologically proven, Stage III or IV, low-grade NHL were registered between April and September, 2002.

Results of a phase II multicenter trial of single-agent gemcitabine in patients with relapsed or chemotherapy-refractory Hodgkin's lymphoma.

This study's objective was to determine the efficacy and safety of gemcitabine in patients with relapsed or chemotherapy-refractory Hodgkin's lymphoma (HL). Twenty-nine patients were enrolled. Eight of the first 10 patients received intravenous gemcitabine (1250 mg/m2) days 1, 8, and 15 every 4 weeks.

Results of a phase II multicenter trial of pentostatin and rituximab in patients with low grade B-cell non-Hodgkin's lymphoma: an effective and minimally toxic regimen.

This study explored the efficacy and toxicity of the combination of pentostatin and rituximab, effective single agents in low-grade non-Hodgkin's lymphoma (NHL). Sixty patients with previously treated low-grade NHL were enrolled. Except for day 1, both drugs were administered weekly for 4 weeks, with week 5 off.

Pegylated liposomal doxorubicin as single-agent treatment of low-grade non-Hodgkin's lymphoma: a phase II multicenter study.

The purpose of this study was to determine the objective response rate, median duration of response, time to disease progression, and survival time and to evaluate the safety of pegylated liposomal doxorubicin in previously treated patients with low-grade non-Hodgkin's lymphoma. Thirty-two patients with low-grade non-Hodgkin's lymphoma were treated and analyzed. Pegylated liposomal doxorubicin 30 mg/m2 was administered intravenously as a single dose on day 1 of each 3-week cycle.
