Lenalidomide, Melphalan, and Prednisone Association Is an Effective Salvage Therapy in Relapsed Plasma Cell Leukaemia

Plasma cell leukemia (PCL) is a rare and aggressive plasma cell disorder, characterized by the presence of a peripheral blood absolute plasma cell count of at least 2 × 109/l and more than 20% circulating plasma cells. The prognosis of PCL patients remains poor. Even by using autologous or allogenic transplant procedures, median survival does not exceed 3 years (Saccaro et al., 2005). Thalidomide, bortezomib and lenalidomide (Revlimid) have emerged as high active agents in the treatment of PCL (Johnston and abdalla, 2002; Musto et al., 2007; Finnegan et al., 2006). In particular, Lenalidomide is a structural analogue of thalidomide with similar but more potent biological activity; it is used as first line therapy in MM (Palumbo et al., 2007; Niesvizky et al., 2007), although information regarding its associated use with dexamethasone use as salvage therapy in PCL derives from anecdotal single case reports (Musto et al., 2008). We would like to describe a case of primary PCL with adverse cytogenetic in which excellent response was achieved with the combination of lenalidomide, melphalan, and prednisone as salvage therapy

Cushing syndrome, metabolic syndrome and inflammation: a suggested way out

Endogenous hypercortisolism is associated with an increased cardiovascular risk. Cushing Syndrome (CS) shares many clinical features with metabolic syndrome, including abdominal obesity, systemic arterial hypertension, insulin resistance, dyslipidemia, and thrombotic diatesis. Moreover, CS represents an interesting pattern of an endocrine disorder associated with chronic lowgrade inflammation which is not blunted by the resolution of hypercortisolism. The proinflammatory state that accompanies the metabolic syndrome may provide a connection between CS, inflammation and metabolic processes, which is highly deleterious for vascular functions. There is evidence that dietary patterns similar to those of the Mediterranean-style diet exert ositive effects on almost all components of the metabolic syndrome and other conditions associated with, including inflammation, insulin resistance, and endothelial dysfunction. Therefore, an intervention strategy based on lifestyle changes may play a role in patients with resolution of hypercortisolism in which the anti-inflammatory effects of cortisol are lost and cytokines levels are increased. In this setting, the Mediterranean healthy dietary pattern may represent an innovative approach in order to improve the disease course and to reduce in the long term the cardiovascular risk of people affected by C

Outcomes after non-cardiac surgery: Mortality, complications, disability, and rehospitalization

In the last 25 years, the number of patients aged ≥75 years undergoing non-cardiac surgery has greatly increased. In elderly patients, frailty is significantly associated with an increased risk of adverse events, functional decline, procedural complications, prolonged hospitalization, and mortality. The relationship between frailty and increased mortality and morbidity requires an appropriate tool of assessment to accurately quantify the patient's clinical and perioperative conditions. The preoperative evaluation of elderly patients candidate for non-cardiac surgery should include assessment of frailty, sarcopenia and malnutrition, as these are related to high surgical risk. For colon-rectal surgery as also for gastric cancer surgery, especially early gastric cancer, the introduction of laparoscopy has yielded considerable benefits in terms of short-term postsurgical outcomes, e.g. lower rate of intraprocedural bleeding and reduced length of hospital stay. Despite the progress made in preoperative assessment, surgical procedures and postoperative management, the improvement of outcomes after non-cardiac surgery in elderly patients remains a challenge and calls for future, well-designed clinical studies.</p

Standardization of BCR-ABL1 p210 Monitoring: From Nested to Digital PCR

The introduction of tyrosine kinase inhibitors in 2001 as a targeted anticancer therapy has significantly improved the quality of life and survival of patients with chronic myeloid leukemia. At the same time, with the introduction of tyrosine kinase inhibitors, the need for precise monitoring of the molecular response to therapy has emerged. Starting with a qualitative polymerase chain reaction, followed by the introduction of a quantitative polymerase chain reaction to determine the exact quantity of the transcript of interest-p210 BCR-ABL1, molecular monitoring in patients with chronic myeloid leukemia was internationally standardized. This enabled precise monitoring of the therapeutic response, unification of therapeutic protocols, and comparison of results between different laboratories. This review aims to summarize the steps in the diagnosis and molecular monitoring of p210 BCR-ABL1, as well as to consider the possible future application of a more sophisticated method such as digital polymerase chain reaction

CALR-positive myeloproliferative disorder in a patient with Ph-positive chronic myeloid leukemia in durable treatment-free remission: a case report

Current diagnostic criteria for Philadelphia-negative myeloproliferative neoplasia (MPN) have been redefined by the discovery of Janus kinase 2 (JAK2), myeloproliferative leukemia (MPL) and calreticulin (CALR) genetic alterations. Only few cases of coexistence of CALR-mutated MPN and Philadelphia-positive chronic myeloid leukemia (CML) have been described so far. Here we report the case of a patient with CML diagnosed in 2001, treated with imatinib and pegylated interferon (IFN) frontline. She reached complete molecular remission (CMR) and discontinued imatinib, maintaining treatment free remission. Due to persistent thrombocytosis, we repeated bone marrow (BM) analysis and diagnosed CARL-mutated essential thrombocythemia (ET). A CALR-positive clone was found to be present since 2001, and was unaffected by imatinib treatment, possibly representing a molecular abnormality arising at stem cell level
