Diagnosis, prognostic factors, and assessment of ALL in adults: 2024 ELN recommendations from a European expert panel.

ABSTRACT: Working groups of the European LeukemiaNet have published several important consensus guidelines. Acute lymphoblastic leukemia (ALL) has many different clinical and biological subgroups and the knowledge on disease biology and therapeutic options is increasing exponentially. The European Working Group for Adult ALL has therefore summarized the current state of the art and provided comprehensive consensus recommendations for diagnostic approaches, biologic and clinical characterization, prognostic factors, and risk stratification as well as definitions of endpoints and outcomes. Aspects of treatment, management of subgroups and specific situations, aftercare, and supportive care are covered in a separate publication. The present recommendation intends to provide guidance for the initial management of adult patients with ALL and to define principles as a basis for future collaborative research.

Optimal Management of Chronic Lymphocytic Leukemia and Economic Constraints.

ABSTRACT: In this article, we carry out an overview on the management options available for chronic lymphocytic leukemia (CLL) patients and discuss possible treatment decisions, taking into account the issue of sustainability and availability. Targeted agents have shown to be superior compared with chemoimmunotherapy (CIT) in terms of progression-free survival in high-risk CLL. In the majority of studies, however, continuous treatment was compared with fixed-duration CIT and no overall survival or progression-free survival-2 (time from randomization to second progression or death) advantage could be documented. Meanwhile, a substantial financial burden on both patients and payers has raised issues about affordability and adherence to treatment. Therefore, value-based pricing of new drugs has been used to set up price negotiation policies in several countries, and fixed-duration therapy has shown to be less costly than continuous treatment. Thus, CIT continues to have a role in the treatment of CLL patients with a favorable genetic profile, that is, with a mutated IGHV gene profile and a wild-type TP53. Targeted treatment represents the preferred choice in patients with an unmutated IGHV gene configuration and/or a TP53 disruption, provided that adherence to treatment is guaranteed and bearing in mind that should costly drugs not be available for frontline treatment, new agents can be very effective as first salvage treatment.

Posaconazole prophylaxis during front-line chemotherapy of acute myeloid leukemia: a single-center, real-life experience.

BACKGROUND: Posaconazole is effective as primary antifungal prophylaxis of invasive fungal diseases in patients with acute myeloid leukemia. DESIGN AND METHODS: The impact of primary antifungal prophylaxis administered during front-line chemotherapy for acute myeloid leukemia was evaluated by comparing 58 patients who received oral amphotericin B (control group) to 99 patients who received oral posaconazole (posaconazole group). The primary endpoint was the incidence of proven/probable invasive fungal diseases. Secondary endpoints included incidence of invasive aspergillosis, survival at 4 and 12 months after the diagnosis of acute myeloid leukemia and costs. RESULTS: Proven/probable invasive fungal diseases were documented in 51.7% of patients in the control group and in 23.2% in the posaconazole group (P=0.0002). Invasive aspergillosis was documented in 43% of patients in the control group and in 15% in the posaconazole group (P=0.002). No survival difference was observed in patients aged over 60 years. In patients aged 60 years or less, a statistically significant survival advantage was observed at 4 months, but no longer at 12 months, in the posaconazole group (P=0.03). It was calculated that in the posaconazole group there was a mean 50% cost reduction for the antifungal drugs. CONCLUSIONS: Primary antifungal prophylaxis with posaconazole during front-line chemotherapy was effective in preventing invasive fungal diseases in a "real-life" scenario of patients with acute myeloid leukemia, resulted in an early but transitory survival advantage in younger patients and was economically advantageous.

Cost analysis of a domiciliary program of supportive and palliative care for patients with hematologic malignancies.

The costs of home care (HC) programs may be tailored to the specific needs of patients with hematological malignancies. The aim of this study was to analyze the use of resources and the costs of a program of HC for four different prognostic groups of patients subdivided according to disease status. Over 2 years, 144 patients with hematological malignancies were assisted at home. Patients were subdivided according to disease status and life expectancy in the following groups: (i) terminal phase, with a life expectancy of 3 months or less; (ii) advanced phase, with a life expectancy of 6 months or less; (iii) chronic phase, with a life expectancy of more than 6 months; (iv) discharged early from the hospital with curable disease, following anticancer chemotherapy. Median mean monthly costs (MMC) in Euro (x) have been compared with the costs of hospitalization (DRG). Among the 4 groups of patients, those discharged early and in terminal phase required the highest mean monthly number of home visits (27.2 and 24.1), transfusions (6.1 and 6.8) and days of care (22.8 and 19.7) respectively. MMC were affected by the following variables: disease status and transfusion requirements. MMC for terminal patients (4,232.50x) and those discharged early (3,986.40x) were higher than those for advanced (2,303.80x) and chronic patients (1,488,30x). The cost of HC was lower than the corresponding DRG charges, but exceeded the district fares for HC of cancer patients. In hematological patients, the costs of HC differ according to disease status and transfusion requirements. For some categories of patients, costs of HC are lower than those of hospitalization, although higher than the current national fares for HC programs.

Treatment of 72 newly diagnosed Waldenstrom macroglobulinemia cases with oral melphalan, cyclophosphamide, and prednisone: results and cost analysis.

BACKGROUND: Current treatment regimens for Waldenstrom macroglobulinemia (WM) are based on the use of oral alkylating agents. Recently, however, other more costly agents have been proposed for the treatment of WM. In the current study, the authors report on results obtained using oral melphalan, cyclophosphamide, and prednisone (MCP) to treat 72 patients with WM, and they compare these results (and the associated costs) with those observed using more aggressive protocols. METHODS: Between July 1973 and April 2002, the authors documented overexpression of the immunoglobulin M paraprotein in 317 consecutive patients. Of these, 100 had newly diagnosed WM, and the 72 who were symptomatic were treated using the MCP protocol. Response rate, overall survival (OS), response duration, freedom from progression (FFP), event-free survival (EFS) duration, toxicity, and cost per course in Euro and U.S. dollars were evaluated for patients receiving this regimen. RESULTS: Seventy-one of 72 patients (99%) were evaluable. Of these patients, 55 (77%) achieved a response; 7 others (10%) experienced disease stabilization, and the remaining 9 (13%) experienced disease progression. After a median follow-up of 72 months (range, 3-195 months), the median durations of EFS, FFP, response, and OS were 47, 55, 64, and 66 months, respectively. No World Health Organization Grade III or IV toxicities were observed, and side effects were limited to transient nausea, emesis, and mild neutropenia. The cost per course of the MCP regimen was $16, similar to that of standard protocols involving chlorambucil and much less than that of more aggressive protocols (price range, $91-11091) proposed for the treatment of WM. CONCLUSIONS: Like chlorambucil-based protocols, the MCP regimen is a cost-effective and safe option for the treatment of patients with WM. Furthermore, the results obtained do not appear to be inferior to those yielded by more expensive, aggressive, and toxic intravenous protocols.
