SummaryBackground Mantle-cell lymphoma is an aggressive B-cell lymphoma with a poor prognosis. Both ibrutinib and temsirolimus have shown single-agent activity in patients with relapsed or refractory mantle-cell lymphoma. We undertook a phase 3 study to assess the effi cacy and safety of ibrutinib versus temsirolimus in relapsed or refractory mantle-cell lymphoma.

Recent advances in the treatment of multiple myeloma (MM) have increased the need for accurate diagnosis of the disease. The detection of bone and bone marrow lesions is crucial in the work-up of MM, and often dictates the decision to start treatment. Furthermore, detection of minimal residual disease (MRD) is important for prognosis and treatment planning, and has underscored an unmet need for sensitive imaging modalities that accurately assess response to therapy in MM. Low dose whole body computed tomography (WBCT) has increased sensitivity compared to conventional skeletal survey (CSS) in the detection of bone disease, and can reveal information leading to changes in therapy and management that could prevent or delay the onset of significant morbidity and mortality related to skeletal-related events. Given the multiple options for detection of bone and bone marrow lesions ranging from CSS to WBCT, positron emission tomography (PET)-CT, and magnetic resonance imaging (MRI), the International Myeloma Working Group has established guidelines on the optimal and standardized use of imaging modalities in different stages of the disease. These recommendations on imaging within and outside of clinical trials will help to standardize the imaging worldwide in order to allow comparison of results and unification of treatment approaches.

Immunoglobulin is a highly diverse autologous molecule able to influence immunity in different physiological and diseased situations. Its effect may be visible both in terms of development and function of B and T lymphocytes. Polyclonal immunoglobulin may be used as therapy in many diseases in different circumstances such as primary and secondary hypogammaglobulinemia, recurrent infections, polyneuropathies, cancer, after allogeneic transplantation in the presence of infections and/or GVHD. However, recent studies have broadened the possible uses of polyclonal immunoglobulin showing that it can stimulate certain sub-populations of T cells with effects on T cell proliferation, survival and function in situations of lymphopenia. These results present a novel and considerable impact of intravenous immunoglobulin (IVIg) treatment in situations of severe lymphopenia, a situation that can occur in cancer patients after chemo and radiotherapy treatments. In this review paper the established and experimental role of polyclonal immunoglobulin will be presented and discussed as well as the manufacturing processes involved in their production.
