Durable complete responses from therapy with combined epratuzumab and rituximab: final results from an international multicenter, phase 2 study in recurrent, indolent, non-Hodgkin lymphoma.

Background: In this international, multicenter trial, the authors evaluated rituximab (anti-CD20) plus epratuzumab (anti-CD22) in patients with postchemotherapy relapsed/refractory, indolent non-Hodgkin lymphoma (NHL), including long-term efficacy.

Methods: Forty-nine patients with follicular NHL (FL) (N = 41) or small lymphocytic lymphoma (SLL) (N = 7) received intravenous epratuzumab 360 mg/m2 and then intravenous rituximab 375 mg/m2 weekly x4. The regimen was tolerated well.

Targeted treatment and new agents in diffuse large B-cell lymphoma.

The concurrent use of rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) has established the utility of chemoimmunotherapy for the treatment of aggressive non-Hodgkin's lymphoma (NHL). However, a substantial number of patients with diffuse large B-cell lymphoma (DLBCL) still die from their disease, and improvements in therapy remain necessary. Numerous efforts have been made to improve prognostic tools in DLBCL, including the International Prognostic Index (IPI).

The "Rosen Triad": tubular carcinoma, lobular carcinoma in situ, and columnar cell lesions.

The histologic triad of tubular carcinoma (TC), columnar cell lesion (CCL), and lobular carcinoma in situ (LCIS) has been recognized, but has not yet been fully characterized. The "Rosen Triad"-named in tribute to its first categorical description by the eponymous pathologist-is a morphologic observation that may have important clinical and pathologic implications. To study these implications, the literature on the topic was reviewed.

FDG-PET in prediction of splenectomy findings in patients with known or suspected lymphoma.

Diagnostic splenectomy is frequently performed in patients with suspected or known lymphoma. We evaluated whether preoperative 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) results may correlate with splenic pathology. Of 165 patients undergoing splenectomy at the Weill Cornell Medical Centre/New York Presbyterian Hospital from 2004 to 2006, 10 were identified as being performed to evaluate known or suspected lymphoma and included a pre-splenectomy FDG-PET scan.

Novel and engineered anti-B-cell monoclonal antibodies for non-Hodgkin's lymphoma.

Over the past decade, the safety and efficacy of the anti-CD20 antibody rituximab has resulted in its use in virtually all patients with B-cell non-Hodgkin's lymphoma (NHL). Unfortunately, many patients who initially benefit from rituximab develop resistance while others may never respond. Both the successes and limitations of rituximab have heralded an explosion in research and development of novel monoclonal antibodies.

Intensive treatment strategies may not provide superior outcomes in mantle cell lymphoma: overall survival exceeding 7 years with standard therapies.

Background: Reported median overall survival (OS) in patients with mantle cell lymphoma (MCL) has been reported to be just 3-4 years. As a consequence, first-line treatment has become more aggressive. Single-center studies with R-Hyper-CVAD and/or autologous stem-cell transplant (ASCT) have produced 3-year OS rates >80%, prompting many to adopt their use.
