Aggressive non-Hodgkin's lymphoma: economics of high-dose therapy

Assessing the charges associated with hematopoietic stem cell mobilization and remobilization in patients with lymphoma and multiple myeloma undergoing autologous hematopoietic peripheral blood stem cell transplantation

BACKGROUND

The purpose of this study was to perform a detailed analysis of the charges associated with chemomobilization and remobilization of autologous hematopoietic stem cells (HSCs) and to quantify medical costs and resource utilization associated with these procedures.

STUDY DESIGN AND METHODS

Patients with lymphoma underwent chemomobilization with ifosfamide and etoposide with or without rituximab (IE ± R). Patients with multiple myeloma (MM) received a modified hyperfractionated cyclophosphamide, vincristine, doxorubicin, dexamethasone (hyper-CVAD) regimen after failing to mobilize with growth factors only.

RESULTS

Between January 2004 and October 2006, 98 patients with lymphoma underwent HSC mobilization with IE ± R. Mobilization with IE ± R was effective, with 90.8% of patients collecting at least 2 × 10(6) CD34+ cells/kg. The total charges for treatment were $27,996 and $37,667 for patients mobilized with IE and IE + R, respectively. Hospital readmission for complications occurred in 26.5% of patients, resulting in additional charges of $10,356. The preapheresis procedure charge was estimated to be $2522, the charge for a 2-day apheresis session was $5160, and the postapheresis phase resulted in charges of $8040. Our analysis determined that reducing apheresis by 1 day has the potential to save $6600. We also performed a retrospective analysis of 16 patients with MM remobilized with a modified hyper-CVAD regimen. Remobilization was successful, with 87.5% of patients. Our analysis determined that mobilization, preapheresis, apheresis, and postapheresis phase charges were $24,968, $2522, $6158, and $12,060, respectively.

CONCLUSIONS

Optimization of HSC mobilization regimens to reduce failure rates would not only benefit patients but also reduce the overall medical costs.

Unintended pregnancy after gonadal failure chemoprevention with gonadotropin-releasing hormone agonist in women with hematologic malignancies

Many patients who receive co-treatment with GnRH agonists (GnRH-a) during chemotherapy treatment preserve their ovarian function and are at risk of unintended pregnancies. Therefore, it is important to offer them effective contraception. Also, pregnancies occurring after cancer therapy in women who received GnRH-a are not associated with adverse neonatal outcomes.

Cost effectiveness of high-dose chemotherapy with autologous stem cell support as initial treatment of aggressive non-Hodgkin's lymphoma

The GOELAMS 072 study showed that first-line high-dose chemotherapy (HDT) with peripheral blood stem cell transplant (PBSCT) support was superior to the standard chemotherapy regimen (cyclophosphamide, doxorubicin, vincristine and prednisone; CHOP) in adults with aggressive non-Hodgkin's lymphoma (NHL). The aim of the study was to evaluate the pharmacoeconomic profile of HDT with PBSCT support relative to standard CHOP therapy as first-line treatment in adults with aggressive NHL. We performed a cost-effectiveness analysis from the French Public Health Insurance perspective, restricted to hospital costs (euro, year 2008 values). The clinical effectiveness criterion was censured overall survival (OS) difference after a median follow-up of 4 years for the entire cohort. A total of 197 patients were included (CHOP, n = 99; HDT, n = 98). Uncertainty was assessed using non-parametric bootstrap simulations and various scenario analyses. Five-year OS did not differ significantly between groups for the entire cohort. Nevertheless, subgroup analyses appeared to be more relevant for decision making: among patients with a high-intermediate risk according to the age-adjusted International Prognostic Index (IPI), HDT yielded a significantly higher 5-year OS than CHOP (74% vs 44%; p = 0.001). Among these patients, the mean censured OS survival, adjusted for time discounting and quality of life (QOL), increased with HDT by 1.20 years (95% CI 1.19, 1.21). The cost per life-year saved with HDT was estimated as euro34 315 (95% CI 32 683, 35 947) in this subgroup. Results suggested that HDT with PBSCT support might be considered a cost-effective strategy among patients with high-intermediate-risk NHL according to the age-adjusted IPI. Its place and its cost effectiveness potential versus, or in combination with, rituximab still need further research.

Economic assessment in the management of non-Hodgkin’s lymphoma

An increasing need for economic evaluations of non-Hodgkin's lymphoma (NHL) treatments exists. We performed a literature review on the currently available NHL economic evaluations, using PubMed and the Cochrane database. English and Dutch language papers on treatment in adults were selected. A total of 88 publications were found, 44 of which were included. Of these, 6 economic evaluation-specific methodological items are evaluated (study perspective, overhead costs, data sources, charges or prices, sensitivity analysis, presentations of resource use and unit costs), enabling readers to judge the value of these studies. The 11 subjects covered by the economic evaluations are discussed. Many NHL treatments remain to be studied in economic evaluations. Future publications should report on the six methodological items in more detail, and preferably tackle them in the recommended way.
