Cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab versus epirubicin, cyclophosphamide, vinblastine, prednisone and rituximab for the initial treatment of elderly "fit" patients with diffuse large B-cell lymphoma: results from the ANZINTER3 trial of the Intergruppo Italiano Linfomi.

Abstract We conducted a prospective study to compare epirubicin, cyclophosphamide, vinblastine, prednisone and rituximab (R-miniCEOP) with cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab (R-CHOP) for the treatment of “fit” elderly patients with diffuse large B-cell lymphoma (DLBCL). Patients over the age of 65 with stage II–IV DLBCL were screened with a comprehensive geriatric assessment. Patients were randomized to receive six courses of R-miniCEOP (n = 114) or R-CHOP (n = 110). Overall, the rate of complete remission was 70% (p = 0.466). After a median follow-up of 42 months, 5-year event-free survival (EFS) rates were 46% and 48% for R-miniCEOP and R-CHOP, respectively (p = 0.538). Patients older than 72 years and with low-risk disease had a better outcome when treated with R-miniCEOP (p = 0.011). Overall R-CHOP and R-miniCEOP are similarly effective for elderly “fit” patients with DLBCL. The less intense R-miniCEOP may be an acceptable option for the treatment of relatively older patients with low-risk disease.

Outcome of frail elderly patients with diffuse large B-cell lymphoma prospectively identified by Comprehensive Geriatric Assessment: results from a study of the Fondazione Italiana Linfomi

Abstract In 2003 the Fondazione Italiana Linfomi (FIL) started a clinical research program for investigating initial treatment of frail elderly patients with diffuse large B-cell lymphoma (DLBCL) identified by Comprehensive Geriatric Assessment (CGA). From 2003 to 2006, 334 elderly patients underwent CGA assessment, and 99 patients were classified as frail. Frail patients had a median age of 78 years, stage III–IV disease in 62% and age-adjusted International Prognostic Index (aaIPI) of 2–3 in 53%. Treatment consisted of several different regimens according to physician discretion. After a median follow-up of 36 months, 5-year overall survival (OS) was 28%. In multivariate analysis, aaIPI 2–3 (p = 0.005) and the presence of respiratory comorbidity (p = 0.044) were the only factors that showed independent correlation with OS. Frail patients had a poorer outcome compared with fit patients also if they were treated with rituximab-containing combination chemotherapy (hazard ratio 2.37, 95% confidence interval 1.48–3.78; p < 0.001). CGA is a valid tool to prospectively identify frail subjects among elderly patients with DLBCL.

Myocardial iron overload assessed by magnetic resonance imaging (MRI)T2* in multi-transfused patients with thalassemia and acquired anemias

BACKGROUND Cardiac complications secondary to iron overload remain a significant matter in patients with transfusion dependent anemias. PATIENTS AND METHODS To evaluate cardiac siderosis, Magnetic resonance imaging T2* (MRI T2*) was performed in 3 cohorts of transfusion dependent patients: 99 with thalassemia major (TM), 20 with thalassemia intermedia (TI), and 10 with acquired anemias (AA). Serum ferritin was measured and all patients underwent echocardiographic evaluation. RESULTS In TM patients cardiac T2* pathologic values (below 20 ms) were found in 37 patients. Serum ferritin was negatively associated with age (r=-0.32, p=0.001) and weakly with T2* values (r=-0.19, p=0.057). A positive correlation was found between T2* and LVEF (r=0.27, p=0.006). Out of 37 patients with T2*<20 ms, 18 (48%) had serum ferritin values<1000 ng/ml. In TI cohort, 3 patients had cardiac T2* pathologic values. In AA cohort, pathologic T2* values were found in 2 patients, who received 234 and 199 PRBC units, respectively, and were both on chelation therapy (in one patient ferritin value was 399 ng/ml). T2* values were negatively associated, but not significantly, with the number of PRBC transfused (r=-0.53, p=0.07). CONCLUSION In our experience, 37% of TM patients had a myocardial iron overload assessed by MRI T2*; this value is higher than in TI patients. Serum ferritin measurement was a poor predictor of myocardial siderosis. In patients with AA, more than 200 PRBC units transfused were required to induce cardiac hemosiderosis, in spite of chelation therapy and, in one patient, of normal ferritin values.

A randomized trial with melphalan and prednisone versus melphalan and prednisone plus thalidomide in newly diagnosed multiple myeloma patients not eligible for autologous stem cell transplant

Several trials comparing the efficacy of standard melphalan and prednisone (MP) therapy with MP plus thalidomide (MPT) in elderly patients with multiple myeloma (MM) have been reported, with inconsistent results. The primary goal of our study was to evaluate the efficacy and toxicity of MP versus MPT in newly diagnosed patients with MM who were transplant-ineligible or over age 65. A total of 135 patients were enrolled. Either minimal response or better or partial response or better were more frequent with MPT treatment (p = 0.001). After a median follow-up of 30 months, median progression-free survival (PFS) and overall survival (OS) were 33 and 52 months for MPT versus 22 and 32 months for MP, respectively. The comparison showed a significant advantage for MPT versus MP in PFS (p = 0.02) and only a trend for OS (p = 0.07). Severe adverse events were observed more frequently with MPT. In conclusion, our results show an improved activity of MPT at a cost of increased toxicity. We believe that MPT can be considered one of the new standard of care for elderly or transplant-ineligible patients with MM.

Chromosome 2p gain in monoclonal B-cell lymphocytosis and in early stage chronic lymphocytic leukemia.

Recent studies have described chromosome 2p gain as a recurrent lesion in chronic lymphocytic leukemia (CLL). We investigated the 2p gain and its relationship with common prognostic biomarkers in a prospective series of 69 clinical monoclonal B‐cell lymphocytosis (cMBL) and 218 early stage (Binet A) CLL patients. The 2p gain was detected by FISH in 17 patients (6%, 16 CLL, and 1 cMBL) and further characterized by single nucleotide polymorphism‐array. Overall, unfavorable cytogenetic deletions, i.e., del(11)(q23) and del(17)(p13) (P = 0.002), were significantly more frequent in 2p gain cases, as well as unmutated status of IGHV (P < 1 × 10−4) and CD38 (P < 1 × 10−4) and ZAP‐70 positive expression (P = 0.003). Furthermore, 2p gain patients had significantly higher utilization of stereotyped B‐cell receptors compared with 2p negative patients (P = 0.009), and the incidence of stereotyped subset #1 in 2p gain patients was significantly higher than that found in the remaining CLLs (P = 0.031). Transcriptional profiling analysis identified several genes significantly upregulated in 2p gain CLLs, most of which mapped to 2p. Among these, NCOA1 and ROCK2 are known for their involvement in tumor progression in several human cancers, whereas among those located in different chromosomes, CAV1 at 7q31.1 has been recently identified to play a critical role in CLL progression. Thus, 2p gain can be present since the early stages of the disease, particularly in those cases characterized by other poor prognosis markers. The finding of genes upregulated in the cells with 2p gain provides new insights to define the pathogenic role of this lesion. Am. J. Hematol. 2013.

Standard dose and prolonged administration of azacitidine are associated with improved efficacy in a real-world group of patients with myelodysplastic syndrome or low blast count acute myeloid leukemia

Azacitidine is the standard of care for higher‐risk myelodysplastic syndromes (MDS). We evaluated factors affecting the outcome of azacitidine treatment in 196 ‘real‐world’ patients, retrospectively collected by two Italian cooperative groups.

Complementary and alternative medicine use in patients with chronic lymphocytic leukemia: an Italian multicentric survey

Abstract Complementary and alternative medicine (CAM) is common in patients with cancer and its use is steadily increasing over time. We performed a multicenter survey in which the use of CAM in 442 Italian patients with chronic lymphocytic leukemia (CLL), the commonest form of leukemia in Western countries, was assessed. Data were collected by means of a face-to-face standardized questionnaire with several items. Mean age was 69 years; 258 patients (58%) were male and 184 (42%) female. Seventy-three patients (16.5%) were found to be CAM users. The most common CAM therapies were green tea, aloe formulations and high dose vitamins. Predictors of CAM use were female gender, younger age, higher education level, internet availability and newspaper reading. The reasons for CAM popularity among these patients are complex. Given the number of patients combining therapy with CAM and its possible drug interactions, doctor interest as well as patient education about CAM should be improved.

Deferasirox chelation therapy in patients with transfusion-dependent MDS: a ‘real-world’ report from two regional Italian registries: Gruppo Romano Mielodisplasie and Registro Basilicata

Deferasirox (DFX) is an orally administered iron chelator approved for use in patients with transfusion‐dependent iron overload due to myelodysplastic syndromes (MDS). The safety and efficacy of DFX has been explored in clinical trial settings, but there is little data on unselected patients with MDS. The aim of this study was to retrospectively evaluate the safety, compliance, efficacy and effect on haematopoiesis of DFX in a large ‘real‐world’ MDS population. One hundred and eighteen patients with transfusion‐dependent MDS were treated with DFX across 11 centres in Italy. Serum ferritin levels, haematological response, dosing, adverse events and transfusion dependence were recorded at baseline, 3, 6, 12 and 24 months following initiation of treatment. DFX reduced mean serum ferritin levels from 1790 to 1140 ng/mL (P < 0.001), with 7.1% of patients achieving transfusion independence. Significant haematological improvement was seen in erythroid (17.6%), platelet (5.9%) and neutrophil counts (7.1%). Adverse events were reported in 47.5% of patients, including gastrointestinal and renal toxicity. Regression analysis showed that higher starting doses of DFX are associated with transfusion independence at 24 months. DFX is a safe, effective treatment for transfusion‐dependent MDS that can lead to transfusion independence and haematological improvement in a subset of patients.

Rituximab with cyclophosphamide, vincristine, non-pegylated liposomal doxorubicin and prednisone as first-line treatment for splenic marginal zone lymphoma: a Fondazione Italiana Linfomi phase II study

Rituximab ® provides high response rates and effective disease palliation in patients with splenic marginal zone lymphoma (SMZL). We conducted a phase II trial in patients with SMZL who were either untreated or were splenectomized but had shown disease progression within 1 year after splenectomy. Treatment consisted of six courses of Rituximab with cyclophosphamide, vincristine, non-pegylated liposomal doxorubicin and prednisone (R-COMP). Fifty-one patients were eligible for the analysis. The overall response rate was 84%. The 6-year progression-free survival and overall survival were 54% and 72%, respectively. Toxicity was substantial (grade ≥ 3 neutropenia: 26%; grade ≥ 3 infections: 8%). Of the 15 deaths, two occurred on treatment (one sepsis and one pneumonia). Six deaths were due to lymphoma progression, four to secondary neoplasia, one to sepsis, one to pneumonia and one to splenectomy complications. R-COMP should be restricted to patients with bulky disease associated with symptoms or to patients with possible histological transformation.

Total body computed tomography scan in the initial work‐up of Binet stage A chronic lymphocytic leukemia patients: Results of the prospective, multicenter O‐CLL1‐GISL study

Total body computed tomography (TB‐CT) scan is not mandatory in the diagnostic/staging algorithm of chronic lymphocytic leukemia (CLL). The aim of this study was to determine the value and prognostic significance of TB‐CT scan in early stage CLL patients. Baseline TB‐CT scan was performed in 240 Binet stage A CLL patients (179 Rai low‐ and 61 Rai intermediate‐risk) included in a prospective multicenter observational study (clinicaltrial.gov ID:NCT00917549). The cohort included 69 clinical monoclonal B lymphocytosis (cMBLs). Patients were restaged considering only radiological data. Following TB‐CT scans, 20% of cases reclassified as radiologic Binet (r‐Binet) stage B. r‐Binet B patients showed a higher incidence of unfavorable cytogenetic abnormalities (P = 0.027), as well as a shorter PFS (P = 0.001). At multivariate analysis, r‐Binet stage [HR = 2.48; P = 0.004] and IGHV mutational status [HR = 3.01; P = 0.002] retained an independent predictive value for PFS. Among 179 Rai low‐risk cases, 100 were redefined as r‐Rai intermediate‐risk based upon TB‐CT scan data, showing a higher rate of cases with higher ZAP‐70 (P = 0.033) and CD38 expression (P = 0.029) and β2‐microglobulin levels (P < 0.0001), as well as a shorter PFS than those with r‐Rai low‐risk (P = 0.008). r‐Rai stage [HR = 2.78; P = 0.046] and IGHV mutational status [HR = 4.25; P = 0.009] retained a significant predictive value for PFS at multivariate analysis. Forty‐two percent of cMBL patients were reclassified as r‐small lymphocytic lymphomas (r‐SLLs) by TB‐CT scan. TB‐CT scan appears to provide relevant information in early stage CLL related to the potential and the timing of patients to progress towards the more advanced disease stages. Am. J.
