Prognostic factors for response and survival in higher-risk myelodysplastic syndrome patients treated with azacitidine (AZA) remain largely unknown. Two hundred eighty-two consecutive high or intermediate-2 risk myelodysplastic syndrome patients received AZA in a compassionate, patient-named program. Diagnosis was RA/RARS/RCMD in 4%, RAEB-1 in 20%, RAEB-2 in 54%, and RAEB-t (AML with 21%-30% marrow blasts) in 22%. Cytogenetic risk was good in 31%, intermediate in 17%, and poor in 47%. Patients received AZA for a median of 6 cycles (1-52). Previous low-dose cytosine arabinoside treatment (P ؍ .009), bone marrow blasts > 15% (P ؍ .004), and abnormal karyotype (P ؍ .03) independently predicted lower response rates. Complex karyotype predicted shorter responses (P ؍ .0003). Performance status > 2, intermediate-and poor-risk cytogenetics, presence of circulating blasts, and red blood cell transfusion dependency > 4 units/8 weeks (all P < 10 ؊4 ) independently predicted poorer overall survival (OS). A prognostic score based on those factors discriminated 3 risk groups with median OS not reached, 15.0 and 6.1 months, respectively (P < 10 ؊4 ). This prognostic score was validated in an independent set of patients receiving AZA in the AZA-001 trial (P ؍ .003). Achievement of hematological improvement in patients who did not obtain complete or partial remission was associated with improved OS (P < 10 ؊4 ). In conclusion, routine tests can identify subgroups of patients with distinct prognosis with AZA treatment. (Blood. 2011; 117(2):403-411)
Rituximab maintenance therapy after transplantation prolonged event-free survival, progression-free survival, and overall survival among patients with mantle-cell lymphoma who were younger than 66 years of age at diagnosis. (Funded by Roche and Amgen; LyMa ClinicalTrials.gov number, NCT00921414 .).
Ibrutinib has revolutionized the management of chronic lymphocytic leukemia and is now being increasingly used. Although considered to be less immunosuppressive than conventional immunochemotherapy, the observation of a few cases of invasive fungal infections in patients treated with ibrutinib prompted us to conduct a retrospective survey. We identified 33 cases of invasive fungal infections in patients receiving ibrutinib alone or in combination. Invasive aspergillosis (IA) was overrepresented (27/33) and was associated with cerebral localizations in 40% of the cases. Remarkably, most cases of invasive fungal infections occurred with a median of 3 months after starting ibrutinib. In 18/33 cases, other conditions that could have contributed to decreased antifungal responses, such as corticosteroids, neutropenia, or combined immunochemotherapy, were present. These observations indicate that ibrutinib may be associated with early-onset invasive fungal infections, in particular IA with frequent cerebral involvement, and that patients on ibrutinib should be closely monitored in particular when other risk factors of fungal infections are present.
The FL2000 study was undertaken to evaluate the combination of the anti-CD20 monoclonal antibody rituximab with chemotherapy plus interferon in the first-line treatment of follicular lymphoma patients with a high tumor burden. Patients were randomly assigned to receive either 12 courses of the chemotherapy regimen CHVP (cyclophosphamide, adriamycin, etoposide, and prednisolone) plus interferon␣2a (CHVP؉I arm) over 18 months or 6 courses of the same chemotherapy regimen combined with 6 infusions of 375 mg/m 2 rituximab and interferon for the same time period (R-CHVP؉I arm). After a median follow-up of 5 years, event-free survival estimates were, respectively, 37% (95% confidence interval [CI], 29%-44%) and 53% (95% CI, 45%-60%) in the CHVP؉I and R-CHVP؉I arm (P ؍ .001). Five-year overall survival estimates were not statistically different in the CHVP؉I (79%; 95% CI, 72%-84%) and R-CHVP؉I (84%; 95% CI, 78%-84%) arms. In a multivariate regression analysis, eventfree survival was significantly influenced by both the Follicular Lymphoma International Prognostic Index score (hazard ratio ؍ 2.08; 95% CI, 1.6%-2.8%) and the treatment arm (hazard ratio ؍ 0.59; 95% CI, 0.44%-0.78%). With a 5-year follow-up, the combination of rituximab with CHVP؉I provides superior disease control in follicular lymphoma patients despite a shorter duration of chemotherapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
