Future directions in radioimmunotherapy for B-cell lymphoma.

Rituximab has become a staple in the management of B-cell non-Hodgkin's lymphoma, but it has limited activity as a single agent, with responses in about half of patients with recurrent follicular and low-grade lymphoma. Radioimmunotherapy (RIT) may surmount inherent or acquired antibody resistance by targeting a radionuclide to tumor cells. This strategy is particularly appealing for B-cell lymphoma because CD20 affords an outstanding target and lymphomas are inherently radiosensitive. The efficacy and safety of RIT have been established in the treatment of relapsed or refractory indolent non-Hodgkin's lymphoma, and yttrium 90 ibritumomab tiuxetan (Zevalin; Biogen Idec Inc, Cambridge, MA) was the first RIT agent to be approved by the US Food and Drug Administration. This supplement to Seminars in Oncology seeks to present hematologists and medical oncologists with the most recent developments in RIT with (90)Y ibritumomab tiuxetan for non-Hodgkin's lymphoma, to clarify the role of the medical oncologist in the administration of the ibritumomab tiuxetan regimen, to indicate how and when RIT with (90)Y ibritumomab tiuxetan may most successfully be integrated into the continuum of treatment for patients with B-cell lymphoma, and to describe ongoing clinical trials with (90)Y ibritumomab tiuxetan in B-cell lymphomas.

Stanford V and radiotherapy for locally extensive and advanced Hodgkin's disease: mature results of a prospective clinical trial.

PURPOSE: To provide more mature data on the efficacy and complications of a brief, dose-intense chemotherapy regimen plus radiation therapy (RT) to bulky disease sites for locally extensive and advanced-stage Hodgkin's disease. PATIENTS AND METHODS: One hundred forty-two patients with stage III or IV or locally extensive mediastinal stage I or II Hodgkin's disease received Stanford V chemotherapy for 12 weeks followed by 36-Gy RT to initial sites of bulky (> or =5 cm) or macroscopic splenic disease. Freedom from progression (FFP), overall survival (OS), and freedom from second relapse (FF2R) were determined using life-table estimates. Outcomes were analyzed according to the international prognostic score. Late effects of treatment were recorded in follow-up. RESULTS: With a median follow-up of 5.4 years, the 5-year FFP was 89% and the OS was 96%. No patient progressed during treatment, and there were no treatment-related deaths. FFP was significantly superior among patients with a prognostic score of 0 to 2 compared with those with a score of 3 and higher (94% v 75%, P <.0001). No secondary leukemia was observed. To date, there have been 42 pregnancies after treatment. Among 16 patients who relapsed, the FF2R was 69% at 5 years. CONCLUSION: These data confirm our preliminary report that Stanford V chemotherapy with RT to bulky disease sites is highly effective in locally extensive and advanced Hodgkin's disease. It is most important to compare this approach with standard doxorubicin, bleomycin, vinblastine, and dacarbazine chemotherapy in the ongoing intergroup trial (E2496) to determine whether Stanford V with or without RT represents a therapeutic advance.

Lymphocyte predominant Hodgkin's disease.

Lymphocyte predominant Hodgkin's disease (LPHD) is a rare type of B-cell lymphoma with unique pathologic and clinical features that distinguish it from other types of Hodgkin's disease. Patients with LPHD tend to be younger males who present with indolent and asymptomatic lymphadenopathy limited to peripheral lymph nodes. The immunophenotype of the malignant lymphocytic and/or histiocytic cells (CD20+, CD15-, CD30-) forms the basis of the pathologic distinction from the subtypes of classical Hodgkin's disease. Despite an excellent response to aggressive upfront combined-modality treatment, patients with LPHD tend to relapse continuously over decades. The benign nature of these relapses and the incidence of late treatment-related toxicity have raised questions about the need for an aggressive upfront approach. Recent insights into the molecular pathogenesis of LPHD and the development of novel targeted therapies promise to improve future treatment.

Hodgkin's disease.

Significant progress has been made over the past decade in the classification, diagnosis, staging, prognosis, and treatment of Hodgkin's disease (HD). A new classification system has recognized differences in the natural history of certain subtypes. The introduction of positron emission tomography has improved the accuracy of non-invasive staging. New prognostic indices have led to the development of risk-adapted treatment strategies. The serious long-term side effects of extended-field radiotherapy have prompted the increasing use of chemotherapy in conjunction with limited radiotherapy for early-stage patients. Combination chemotherapy remains the treatment of choice for advanced HD, and new dose-intense regimens appear to have improved activity. Patients who relapse now have a more favorable prognosis with the availability of active salvage regimens, autologous stem cell transplantation, and novel biologic agents.
