A rare case of appendicular skeleton localization in a patient with chronic lymphocytic leukemia successfully treated with salvage radiation therapy

Bone involvements in chronic lymphocytic leukemia (CLL) are considered rare events, and the English-language medical literature describes them only in sporadic case reports. Consequently, robust indications for a rational clinical management are lacking. We report the case of a middle-aged man in clinical follow-up for CLL who experienced pain at the right tibial level that was refractory to nonsteroidal anti-inflammatory drugs and an acute episode of anemia. Instrumental examinations and a bioptic sample surprisingly demonstrated a bone tibial localization by CLL

Determinants of frontline tyrosine kinase inhibitor choice for patients with chronic-phase chronic myeloid leukemia: A study from the Registro Italiano LMC and Campus CML

Background: Imatinib, dasatinib, and nilotinib are tyrosine kinase inhibitors (TKIs) approved in Italy for frontline treatment of chronic-phase chronic myeloid leukemia (CP-CML). The choice of TKI is based on a combined evaluation of the patient's and the disease characteristics. The aim of this study was to analyze the use of frontline TKI therapy in an unselected cohort of Italian patients with CP-CML to correlate the choice with the patient's features. Methods: A total of 1967 patients with CP-CML diagnosed between 2012 and 2019 at 36 centers throughout Italy were retrospectively evaluated; 1089 patients (55.4%) received imatinib and 878 patients (44.6%) received a second-generation (2G) TKI. Results: Second-generation TKIs were chosen for most patients aged <45 years (69.2%), whereas imatinib was used in 76.7% of patients aged >65 years (p < .001). There was a predominant use of imatinib in intermediate/high European long-term survival risk patients (60.0%/66.0% vs. 49.7% in low-risk patients) and a limited use of 2G-TKIs in patients with comorbidities such as hypertension, diabetes, chronic obstructive pulmonary disease, previous neoplasms, ischemic heart disease, or stroke and in those with >3 concomitant drugs. We observed a greater use of imatinib (61.1%) in patients diagnosed in 2018-2019 compared to 2012-2017 (53.2%; p = .002). In multivariable analysis, factors correlated with imatinib use were age > 65 years, spleen size, the presence of comorbidities, and ≥3 concomitant medications. Conclusions: This observational study of almost 2000 cases of CML shows that imatinib is the frontline drug of choice in 55% of Italian patients with CP-CML, with 2G-TKIs prevalently used in younger patients and in those with no concomitant clinical conditions. Introduction of the generic formulation in 2018 seems to have fostered imatinib use

Darbepoetin alfa for the treatment of anemia associated with myelodysplastic syndromes: Efficacy and quality of life

To evaluate efficacy, safety, changes in biological features, and quality of life (QoL) in low-risk anemic patients with MDS treated with darbepoetin alfa (DPO), 41 patients received DPO 150 μg weekly for 24 weeks. The dose was increased to 300 μg weekly in non-responsive patients. During treatment, 10/17 (59) transfusion-dependent (TD) and 13/23 (56) transfusion-free (TF) patients responded. In TF patients, Hb increased from 9.2±0.9g/dL to 10.3±1.4g/dL by 24 weeks (p0.004). The mean response duration was 22 weeks (95 CI: 19.724.0) in TF patients compared with 15.1 weeks (95 CI: 13.317.5) in TD patients. Response to treatment was associated with increases in QoL. Decreases in the percentage of apoptotic progenitor cells (p0.007) and CD34 cells (p0.005) were observed. These results confirm previous studies demonstrating the safety and efficacy of DPO in anemic patients with MDS. Biological changes and improvement in QoL were associated with response. Adequate dosing is to be determined. © 2010 Informa Healthcare USA, Inc

Clinical relevance of hypogammaglobulinemia, clinical and biologic variables on the infection risk and outcome of patients with stage A chronic lymphocytic leukemia

The prognostic effect of hypogammaglobulinemia (HGG), clinical and biologic characteristics on the infection risk and outcome has been retrospectively analyzed in 899 patients with stage A chronic lymphocytic leukemia (CLL). Low levels of IgG were recorded in 19.9% of patients at presentation, low levels of IgM and/or IgA in 10.4% and an additional 20% of patients developed HGG during the course of the disease. Before the start of any treatment, 160 (12.9%) patients experienced at least one grade ≥3 infection requiring a systemic anti-infective treatment and/or hospitalization. While IgG levels at diagnosis were not associated with an increased risk of grade ≥3 infection or with an adverse outcome, a significantly increased rate of grade ≥3 infections was recorded in patients with unmutated IGHV (p=0.011) and unfavorable FISH aberrations (p=0.009). Late onset HGG, more frequently recorded in patients with Rai stage I-II (p=0.001) and unmutated IGHV (p=0.001), was also associated with a higher rate of severe infections (p=0.002). These data indicate that, stage A patients with clinical and biologic characteristics of a more aggressive disease develop more frequently late onset HGG, grade ≥3 infections and require a closer clinical monitoring

Bendamustine, Low-dose dexamethasone, and lenalidomide (BdL) for the treatment of patients with relapsed/refractory multiple myeloma confirms very promising results in a phase I/II study

Lenalidomide and dexamethasone are an effective treatment for naïve and relapsed multiple myeloma (MM) patients. Bendamustine is a good option for B-cell malignancies showing only partial cross resistance with alkylating agents used in MM patients. Based on these considerations, we proposed a phase I/II study testing escalating doses of bendamustine and lenalidomide and fixed low doses of dexamethasone (BdL). Fifteen patients were enrolled in phase I study. Maximum tolerated dose was established at dose “level 0”: bendamustine 40 mg/m2 days 1,2; lenalidomide 10 mg days 1–21; d 40 mg days 1,8,15,22 every 28-day cycle, for six cycles. We enrolled 23 patients in the phase II study. BdL combination showed mainly hematological toxicities, fever and infections. Overall response rate was 47%. After median follow up of 22 months, median PFS was 10 months. Two-years OS rate was 65%. BdL combination confirmed to be a promising treatment for patients with relapsed/refractory MM
