Allogeneic bone marrow transplant is the only potentially curative treatment, while drug therapies aim only to reduce spleen size, constitutional symptoms, and anemia [[4]]. Standard treatment for AMF involves corticosteroids and immunosuppressive therapies [[9]]. Bone marrow fibrosis (BMF) is usually associated with malignant neoplasms (mainly by myeloproliferative disorders), but in a minority of cases, it is due to non-neoplastic causes [[1]]. Taking the above into account, in September 2015, after six months of steroid suspension and 18 months of continuous Ruxolitinib treatment, it was decided to reevaluate the disease to verify if a clonal process caused the BMF or if the fibrosis was associated with the autoimmune disease.

Anti-CD19 chimeric antigen receptor (CAR) T cells represent the first approved third-line therapy associated with long-term remissions in patients with refractory/relapsed (R/R) diffuse large B-cell lymphoma (DLBCL). Eligibility criteria to identify patients who can successfully receive CAR-T are still debated. For this reason, the aim of this study was to identify factors influencing eligibility and define a realistic patient estimate. Of 1100 DLBCL patients, 137 were included. Based on the Juliet trial inclusion criteria, only 64 patients (46.7%) would be eligible. Median overall survival (OS) was 8.04 months in eligible vs 3.23 in non-eligible patients (p < 0.001). Multivariate analysis identified stage III-IV (p = 0.017) and ECOG ≥ 2 (p < 0.001) as significant independent prognostic factors for OS. Moreover, only 64/1100 (5.8%) DLBCL patients would be truly eligible for CAR-T. Our real-life data confirm that with a longer waiting time patients with advanced stage and poor ECOG are less likely to be eligible for CAR-T cell infusion. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Male gender was recently reported as an adverse prognostic factor in patients with diffuse large B-cell lymphoma (DLBCL) treated with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone). We conducted a retrospective study of adult patients with DLBCL initially treated with rituximab containing regimens between 2001 and 2007. Patients were identified from the clinical archives of 43 Italian and Brazilian institutions. The principal endpoint was overall survival (OS). One thousand seven hundred and ninety-three patients were fully eligible for the study. Thirty-eight percent, 27%, 22% and 12% of patients had an International Prognostic Index (IPI) score of 0-1, 2, 3 and 4-5, respectively; 53% were males. After a median follow-up of 36 months (1-106), the 5-year OS was 76% (95% confidence interval 74-78%). In univariate analysis, male gender was an adverse prognostic factor with a hazard ratio of 1.52. In multivariate analysis, when adjusted by IPI, again gender maintained its prognostic relevance, showing an independent additive effect. In conclusion, in patients with DLBCL treated with rituximab containing regimens, gender may increase the predictive power of the IPI. Based on these results, given possible differences in blood clearance of rituximab between males and females, the benefit of higher doses of rituximab in males should be explored.

Polymorphisms of the Glutathione-S Transferase (GST) family may influence the prognosis in lymphoma patients. We aimed to validate the impact of GSTT1 and GSTM1 deletions and of the GSTP1Ile105Val polymorphism on outcome and toxicity in 140 patients with advanced Hodgkin's lymphoma enrolled in the prospective multicenter HD2000-GISL trial, comparing ABVD, BEACOPP and CEC regimens. Carriers of the GSTP1Ile105Val polymorphism had a higher rate of grade 3-4 anemia following treatment. Overall, our study failed to validate GST genotyping as prognostic factor for progression-free survival (PFS). Only the small cohort of patients with an international prognostic score (IPS) >3 and undeleted GSTT1 and/or GSTM1, treated with ABVD had worse progression-free survival (PFS) (GSTT1 ++ vs GSTT1−: HR 5.02, 95% C.I., 1.16-21.8, p == 0.031, GSTM1 ++ /GSTT1 ++ vs GSTM1−and/or GSTT1−: HR 4.61, 95% C.I. 1.28- 16.6, p == 0.019, respectively). No differences were observed for patients treated with intensified regimens, as BEACOPP and CEC. In conclusion, the prognostic role of GST polymorphism, if at all, is limited to a small subgroup of patients treated with standard ABVD regimen. [ABSTRACT FROM AUTHOR]

We conducted a population-based study to assess how positron emission tomography (PET) is currently used in patients with Hodgkin lymphoma (HL). Four cancer registries from northern Italy were used to identify patients with HL diagnosed from 2006 to 2008. Computed tomography (CT) and PET scans were collected before treatment start (B), at the end (F), and during treatment (I). One hundred and thirty-six patients were identified as the study population. B-PET, I-PET, and F-PET were performed in 82%%, 65%%, and 85%% of patients, respectively. Overall, I-PET was coded as positive in 16%% of cases. F-PET was positive in 13%% of cases. The I-PET result was a prognostic factor for failure-free survival (FFS) (hazard ratio [[HR]] 5.33); the F-PET result was the only prognostic factor for overall survival (OS) (HR 14.2). This population-based study confirms the prognostic role of I-PET for FFS also in daily practice; the results of F-PET can be used to predict OS. [ABSTRACT FROM AUTHOR]

We conducted a retrospective analysis on 168 adult patients with newly diagnosed, limited-stage (I and II) diffuse large B-cell lymphoma (DLBCL) treated from 1988 to 2004 with PROMECE-CYTABOM (P-C) plus involved-field radiation therapy (IF-RT). At the end of P-C, the overall response rate was 92%. Radiotherapy (RT) was delivered to 84% of cases. With a median follow-up of 95 months, overall survival (OS), relapse free survival (RFS), and failure free survival at 5 and 10 years was 84% and 77%, 81% and 75%, 71% and 67%, respectively. Age (>60 years, p = 0.002), serum albumin (<3.5 g/dL; p = 0.015), and RT ( p < 0.001) were independent predictors of OS. For patients in complete remission the administration of RT didn't improve both RFS and OS. This study confirms that patients with localized aggressive lymphoma have a high chance of cure with anthracycline containing regimens. Though the regimen used to treat these patients does not contain rituximab, results are considered excellent both in terms of efficacy and safety. [ABSTRACT FROM AUTHOR]

In order to elucidate the role of anthracycline based combination chemotherapy regimens for the treatment of follicular lymphoma we conducted a retrospective study on a large series of patients with a histologically confirmed diagnosis of follicular lymphoma. The Italian lymphoma intergroup (ILI) promoted a retrospective study of patients with follicular lymphoma treated in cooperative trials between 1985 and 1996. Six hundred and thirty three cases were treated with an anthracycline-containing regimen and 128 patients were treated without anthracyclines. The two groups were prognostically comparable; in particular, no difference was observed according to both IPI and ILI prognostic index. Results showed a complete remission (CR) rate for patients treated with anthracyclines was 69.2% and overall response rate was 92.5%. After a median follow-up of 51 months (54 months for patients still alive), the 5- and 10-year overall survival (OS) rates were 80 and 66%, respectively. Disease-free survival (DFS) and failure-free survival (FFS) rates at 5 years were 61 and 49%, respectively. In the group of patients treated with combination chemotherapy not including anthracyclines, the CR rate was 67.5% and the overall response rate was 85.4%. A longer OS (80% at 5 years) was observed in patients treated with anthracyclines compared to 67% OS rate in patients treated without anthracyclines ( p =0.0004). FFS was significantly longer in patients treated with anthracyclines (49 vs. 34% p =0.006 ). Patients treated with anthracyclines with low or intermediate risk according to ILI prognostic index showed a significantly longer OS ( p =0.0001 and p =0.0009, respectively); those in the high-risk group showed a trend for a longer survival. In conclusion, this retrospective study shows that patients with follicular lymphoma treated with an anthracycline containing regimen had a better outcome compared to patients treated with other combination regimens non including anthracyclines in terms of CRs, OS and FFS. On the basis of these results anthracycline-containing regimens (ACR) should be considered as the standard treatment of patients with advanced follicular lymphoma. [ABSTRACT FROM AUTHOR]

Only recently both the Revised European American Lymphoma (REAL) and World Health Organization (WHO) classifications clearly identified indolent non-follicular non-Hodgkin's lymphoma (NHL) as a distinct group of precise histological entities. Therefore, prognostic models, specifically designed for this NHL subset, are still lacking. In this study, we prospectically evaluated the prognostic criteria proposed by the Gruppo Italiano per lo studio dei Iinfomi (GISL) to identify patients with an indolent non-progressive clinical course, eligible for a watch and wait policy within this histological subset defined according to stringent criteria of histomorphology and immunophenotype. Fifty-three patients affected with small lymphocytic, marginal zone, lymphoplasmacytic lymphoma and lacking at presentation the following: B symptoms, bulky disease, anemia, thrombocytopenia, diffuse pattern of bone marrow infiltration and short tumor doubling time, were registered in a prospective therapeutic GISL trial and addressed to a watch and wait program. After 41.3 months of median follow-up, the median progression free survival (PFS) was not reached and 73% of cases did not progress. When additional variables were considered, in order to improve the prognostic model, it was evident that LDH level and the number of extranodal sites were of statistical significance in the multivariate analysis. Based on this finding, a prognostic score was devised which was able to further identify a small group of patients more likely to undergo early progression, and thus suitable for immediate treatment. In conclusion, the GISL definition of indolent disease is a reliable tool to design the appropriate therapeutic strategy in this histological setting. [ABSTRACT FROM AUTHOR]
