Pomalidomide experience: an effective therapeutic approach with immunomodulatory drugs in a patient with relapsed-refractory multiple myeloma.

Here we discuss the case of a heavily pretreated male patient with relapsed-refractory multiple myeloma and previous monoclonal gammopathy of undetermined significance who initiated a fifth-line treatment with pomalidomide (4 mg orally, days 1-21 of a 28-day cycle) and low-dose dexamethasone (40 mg weekly orally). A total of 3 months later, very good partial response was achieved and complete response was maintained for 7 months. This case illustrates the field-practice experience on the benefits of pomalidomide in a relapsed-refractory multiple myeloma patient with a previous history of monoclonal gammopathy of undetermined significance.

Clinical Impact of the Immunome in Lymphoid Malignancies: The Role of Myeloid-Derived Suppressor Cells.

The better definition of the mutual sustainment between neoplastic cells and immune system has been translated from the bench to the bedside acquiring value as prognostic factor. Additionally, it represents a promising tool for improving therapeutic strategies. In this context, myeloid-derived suppressor cells (MDSCs) have gained a central role in tumor developing with consequent therapeutic implications.

Early measurement of CD34+ cells in peripheral blood after cyclophosphamide and granulocyte colony-stimulating factor treatment predicts later CD34+ mobilisation failure and is a possible criterion for guiding "on demand" use of plerixafor.

Background: Early identification of predictive factors of failure to mobilise CD34+ cells could enable rational use of plerixafor during first mobilisation, avoiding the need for a second mobilisation course. However, "on demand" administration of plerixafor needs to be driven by established parameters to avoid inappropriate use.

Materials And Methods: To address this issue, we studied the value of the peripheral blood CD34+ count, measured early (on days +10, +11, +12 and +13), in predicting the mobilisation outcome in the ensuing days.
