ABSTRACT

Immune dysfunction in patients with MM affects both the innate and adaptive immune system. Molecules involved in the immune response pathways are essential to determine the ability of cancer cells to escape from the immune system surveillance. However, few data are available concerning the role of immune checkpoint molecules in predicting the myeloma control and immunological scape as mechanism of disease progression. We retrospectively analyzed the clinical impact of the CD200 genotype (rs1131199 and rs2272022) in 291 patients with newly diagnosed MM. Patients with a CD200 rs1131199 GG genotype showed a median overall survival (OS) significantly lower than those with CC+CG genotype (67.8 months versus 94.4 months respectively; p: 0.022) maintaining significance in the multivariate analysis. This effect was specially detected in patients not receiving an autologous stem cell transplant (auto-SCT) (p < 0.001). In these patients the rs1131199 GG genotype negatively influenced in the mortality not related with the progression of MM (p: 0.02) mainly due to infections events.

ABSTRACT

Fundamento y objetivo: Varios estudios han demostrado la viabilidad de trasplante de células madre autólogas (ASCT) en pacientes con linfoma y el virus de la inmunodeficiencia humana (VIH). La infección por VIH se ha descrito como un factor de riesgo para la movilización de los pobres. El objetivo de este estudio fue comparar los resultados de dos estrategias de movilización de las células madre sanguíneas periféricas (CMSP) en pacientes con linfoma y la infección por VIH en siete hospitales españoles. Pacientes y métodos: Las variables recogidas fueron: características demográficas, clínicas y biológicas, quimioterapias anteriores y los resultados, así como las estrategias de movilización de (clasificados en dos grupos: 1) G-CSF, y 2) el G-CSF de quimioterapia +). Resultados: Entre enero de 2000 y mayo de 2010, 42 pacientes con linfoma y la infección por VIH fueron remitidos para ASCT. La tasa de éxito en la movilización (colección> 1,60 × 10 6 células CD34 / kg) con el primer régimen fue del 67%, sin diferencias entre los pacientes movilizados con G-CSF o con G-CSF + quimioterapia (16 [72%] y 12 [60%], respectivamente, p = 0,382). El estado del linfoma en el momento de la movilización fue el único factor para la movilización de éxito (20/22 pacientes [91%] en remisión completa [RC] movilizado adecuadamente frente a 5/12 [58%] en remisión parcial [RP], p = 0,038). Conclusiones: En los pacientes con linfoma y la infección por el VIH, la movilización con G-CSF fue tan eficaz como la movilización con quimioterapia seguida de G-CSF. El estadio de la enfermedad antes de la movilización fue el principal factor de riesgo para el éxito de la movilización, con mejores resultados en los pacientes movilizados en remisión del linfoma (AU)


Background and objective: Several studies have demonstrated the feasibility of autologous stem cell transplantation (ASCT) in patients with lymphoma and human immunodeficiency virus (HIV) infection. HIV infection has been described as a risk factor for poor mobilization. The aim of this study was to compare the results of two mobilization strategies of peripheral blood stem cells (PBSC) in patients with lymphoma and HIV infection in seven Spanish hospitals. Patients and methods: The following variables were collected: demographic, clinical and biological features, previous chemotherapies and outcomes, as well as mobilization's strategies (classified in two groups: 1) G-CSF, and 2) G-CSF + chemotherapy). Results: Between January 2000 and May 2010, 42 patients with lymphoma and HIV infection were referred for ASCT. The rate of successful mobilization (collection >1.60 × 106 CD34 cells/kg) with the first regimen was 67%, with no differences between those patients mobilized with G-CSF or with G-CSF + chemotherapy (16 [72%] and 12 [60%], respectively; p=0.382). The status of the lymphoma at the time of mobilization was the only factor for successful mobilization (20/22 patients [91%] in complete remission [CR] mobilized adequately versus 5/12 [58%] in partial remission [PR]; p=0.038). Conclusions: In patients with lymphoma and HIV infection, mobilization with G-CSF was as effective as mobilization with chemotherapy followed by G-CSF. The stage of disease prior to the mobilization was the main risk factor for the success of mobilization, with better results in patients mobilized in remission of the lymphoma (AU)
