The Best Treatment for Diffuse Large B-Cell Lymphoma: A German Perspective

While some improvement was achieved by adding etoposide and shortening the treatment intervals from 3 to 2 weeks (CHOEP-14), best results in young good-prognosis patients (age-adjusted International Prognostic Index [IPI] = 0,1) have been achieved with six cycles of CHOP (cyclophosphamide, doxorubicin HCl, vincristine [Oncovin], prednisone)-like chemotherapy in combination with the anti-CD20 antibody rituximab (Rituxan). The role of additional radiotherapy in this setting remains to be determined. With this approach, 2-year eventfree survival rates of > 90% and overall survival of > 95% can be achieved in a very favorable subgroup (patients without IPI risk factor and no bulky disease), while further improvement is warranted for the less favorable subgroup (event-free survival only 77%). For young poorprognosis patients (age-adjusted IPI ≥ 2), the 5-year survival is around 50%, and progress has not been convincingly and specifically demonstrated in these patients. Ongoing studies will show whether dose-dense conventional or high-dose chemotherapy regimens requiring stem cell support in combination with rituximab will result in similar improvements of outcome as has been reported recently for young patients with good-prognosis aggressive lymphoma. In elderly patients, CHOP interval reduction from 3 to 2 weeks (CHOP-14) and the addition of rituximab to CHOP-21 achieved similar improvements in outcome. The ongoing RICOVER-60 (rituximab with CHOP over 60) trial of the German High-Grade Non-Hodgkin’s Lymphoma Study Group (DSHNHL) evaluates whether the combination of both approaches (R-CHOP-14) can further improve the prognosis of elderly patients.

European Experience With Oral Solution and Intravenous Itraconazole

The availability of an improved oral solution and an intravenous (IV) formulation of itraconazole (Sporanox) promises to have an effect on prevention and treatment of fungal infection in immunocompromised patients. Use of itraconazole in neutropenic patients with hematologic malignancies has been evaluated in a number of European studies. Treatment with IV followed by oral itraconazole resulted in response or stable disease in two-thirds of patients with invasive pulmonary aspergillosis. Empiric treatment with IV followed by oral solution itraconazole was at least as effective as, and significantly less toxic than, amphotericin B. Several studies of oral solution prophylaxis indicate effectiveness in prevention of fungal infection. Oral solution and IV itraconazole are useful in a variety of situations in prophylaxis, empiric therapy, and treatment of probable/confirmed infection. Itraconazole exhibits a broad spectrum of activity against Aspergillus and Candida species. It has potential advantages over fluconazole (Diflucan), which does not exhibit in vitro activity against Aspergillus and most non-albicans Candida species, and amphotericin B, which is associated with a high incidence of toxicity. Aggressive use of itraconazole and amphotericin B preparations in treatment of fungal infection at Royal Free Hospital may have reduced mortality associated with aspergillosis.
