Correspondence in reference to the previously published manuscript: Reduction of cycles of bendamustine plus rituximab therapy in the cases with good response for indolent B-cell lymphomas.

Takezaki et al. analyzed the outcome of 57 patients with indolent lymphomas treated with Bendamustine plus Rituximab (BR) according to the number of cycles received, showing that patients who discontinued BR after four cycles had similar outcomes compared to patients who received five or six cycles. Considering the similarities but also the differences between indolent lymphomas and chronic lymphocytic leukemia (CLL), we enriched the results obtained with a cohort of CLL patients treated with BR starting from the experience of the Lazio region group on CLL. Out of 115 patients, 97 (84%) received 4-6 cycles of BR, while 18 (16%) received 1-3 cycles. The outcome of the group of patients who received at least 4 cycles was superior in terms of response rate (ORR 96% vs. ORR 83%, p = 0.041; CR 58% vs. CR 28%, p = 0.052 respectively) and PFS [median PFS 52.6 (40.3-64.9) versus 26.2 (19.3-33.0) months, p < 0.001]. The number of patients undergoing 4 cycles of BR (4-cycles group) and 5-6 cycles (over-4-cycles group) was 9 and 88, respectively. Compared to analysis conducted by the Japanese group in indolent lymphomas, in CLL we did not observe any difference between the outcome of the 4-cycles group and the over-4-cycles group in terms of ORR (89% vs. 97%, p = 0.268) and in survival [median PFS 40.8 (13.7-67.8) versus 52.6 (38.7-66.5) months, p = 0.117]. Moreover, we observed that patients who achieved a clinical CR showed overlapping outcomes with patients who received more than 4 cycles [CR vs. non-CR median PFS not reached vs. 11.0 months; over-4-cycles group median PFS 52.6 months (40.3-64.9); p < 0.001]. Nowadays chemoimmunotherapy with BR is reserved to fit elderly CLL patients, and there are many chemo-free treatment options available; therefore, discontinuation after 4 cycles may be permissible in patients who obtained a CR in order to limit toxicity as much as possible.

Safety and effectiveness of ruxolitinib in the real-world management of polycythemia vera patients: a collaborative retrospective study by pH-negative MPN latial group.

Ruxolitinib is approved for polycythemia vera (PV) patients after failure to previous cytoreductive therapy, based on durable results observed in phase 3 trials. We report a multicenter retrospective study demonstrating the efficacy and safety of ruxolitinib in real-life setting. Eighty-three patients were evaluated. Median follow-up was 24.5 months (IQR 14.0-29.3). At a 3-month response assessment, ruxolitinib provided significant benefit in reducing hematocrit (HCT) level (p < 0.001), phlebotomy requirement (p < 0.001), leucocytes (p = 0.044), and disease-related symptoms (p < 0.001). The exposure-adjusted rates (per 100 patient-years) of infectious complications, thromboembolic events, and secondary malignancies were 6.9, 3, and 3.7, respectively. Non-melanoma skin cancers (NMSC) were the most frequent (40%) SM type. Lymphoproliferative disorders were not detected. Five (6%) patients permanently discontinued ruxolitinib treatment and four (5%) evolved in myelofibrosis (MF), but none in acute leukemia. The rate of MF evolution per 100 patient-years of exposure was 2.8. In our experience, ruxolitinib confirmed its efficacy and safety outside of clinical trials.

Anagrelide in Essential Thrombocythemia (ET): Results from 150 patients over 25 years by the "Ph1-negative Myeloproliferative Neoplasms Latium Group".

BACKGROUND AND AIMS: Anagrelide is a drug effective in reducing platelet counts in essential thrombocythemia (ET) and Ph1-negative myeloproliferative neoplasms. The aim of this study was to evaluate the real-life use of anagrelide in patients with ET followed over 25 years at the Haematological Institutes belonging to "Ph1-negative Myeloproliferative Neoplasms Latium Group." PATIENTS AND METHODS: Eligibility criteria were diagnosis of ET and treatment with anagrelide. Data were collected through an ad hoc case report form. RESULTS: One hundred and fifty patients received anagrelide for a median time of 7.4 years (0.1-23.2). Anagrelide was administered as first-line therapy in 34.7% of patients, as second-line in 52% and as third-line in 13.3%: 85.4% responded to therapy. Sixty-eight/136 evaluable patients reported side effects: palpitations, peripheral vasodilation, anaemia, diarrhoea and gastric distress. Fourteen thrombotic (arterial 10, venous 4) and 51 bleeding events (minor 48, major 3) occurred. Sixteen/150 (10.6%) patients developed secondary myelofibrosis and 3/150 (2%) an acute myeloid leukaemia. CONCLUSIONS: In our experience, anagrelide is an effective drug in reducing platelet levels in a high percentage of patients with ET. It is especially addressed to younger people. A careful assessment of the thrombotic risk and monitoring of cardiac function, at diagnosis and during follow-up, is mandatory.

Preliminary results of a counselling programme for fertility preservation in female cancer patients: The experience of the GEMME DORMIENTI network.

OBJECTIVE: To describe a population of patients referred for fertility preservation (FP), how to efficiently provide FP care, and how FP care changed over time. METHODS: This longitudinal observational study enrolled 281 female cancer patients referred between 2013 and 2016 to the non-profit organisation Gemme Dormienti ONLUS (GD) for FP care. All patients underwent the same battery of instrumental and laboratory diagnostic tests. GnRHa therapy was started at least seven days before CTh treatment. RESULTS: From 2013 to 2016, we observed a progressive increase in the number of patients referred for FP care. Out of 251 eligible patients, 135 patients were treated with GnRHa only, and 72 patients underwent GnRHa therapy and cryopreservation. The median time from GD referral to oocyte and ovarian tissue cryopreservation was 11 and 5 days respectively. Tissue cryopreservation requests increased during our study period (from four cases in 2013 to 17 cases in 2016). During follow-up, 17ß-estradiol and FSH levels were significantly increased (p < .0001), and AMH levels were significantly decreased (p < .0001). CONCLUSION: The rapid increase in the number of patients who requested FP care and in the complexity of FP procedures overtime reflects the need to improve quality of life for cancer patients.

Treatment of Philadelphia-negative myeloproliferative neoplasms in accelerated/blastic phase with azacytidine. Clinical results and identification of prognostic factors.

There have been some reports on a possible role of azacytidine (AZA) in the treatment of accelerated/blastic phase evolved from Philadelphia-negative myeloproliferative neoplasms (MPN-AP/BP), but results are conflicting. In this study, we analyzed a cohort of 39 patients with MPN-AP/BP treated frontline with AZA at the standard dosage (75 mg/m2 ). Median time from diagnosis to AP/BP evolution was 92.3 months (IR 29.9-180.1). All patients were evaluable for hematologic response: two patients (5.2%) died early after AZA initiation, 13 patients (33.3%) had a progressive or stable disease, nine (23.1%) had a hematologic improvement (HI), seven (17.9%) achieved a partial response (PR), and eight (20.5%) a complete response (CR). Overall, 24 patients achieved a clinical hematologic response (HI + PR + CR), with an overall response rate of 61.5%. Median overall survival (OS) from AZA start of the whole cohort was 13.5 months (95% CI, 8.2-18.7). There was no difference in median OS among patients with HI, PR, or CR (P = .908). These three subgroups as "responders" having been considered, a significantly better OS was observed in responder compared with nonresponder patients, with a median OS of 17.6 months (95% CI, 10.1-25.0) versus 4.1 months (95% CI, 0.4-10.0) (P = .001) Only female gender was significant for both achievement of response (.010) and OS duration (P = .002). In conclusion, AZA is useful for the management of MPN-AP/BP, with an overall response rate (HI + PR + CR) of 61.5% and a longer OS in responders.

Cyclophosphamide's addition in relapsed/refractory multiple myeloma patients with biochemical progression during lenalidomide-dexamethasone treatment.

OBJECTIVE: The aim of this study was to evaluate the addition of cyclophosphamide in relapsed-refractory multiple myeloma patients (RRMM) who experienced biochemical relapse or progression without CRAB, during treatment with lenalidomide and dexamethasone (Rd), to slow down the progression in active relapse. METHODS: This analysis included 31 patients with RRMM treated with Rd who received cyclophosphamide (CRd) at biochemical relapse. The CRd regimen was continued until disease progression. RESULTS: The median number of CRd cycles administered was 8 (range: 1-35). A response was observed in 9 (29%) patients. After a median observation time of 11 months, the median overall survival (OS) from the beginning of CRd was 17.7 months. The median progression-free survival (PFS) from the beginning of CRd was 13.1 months. CONCLUSION: The addition of cyclophosphamide delays the progression in patients who present a biochemical relapse during Rd treatment. The response rate and the duration of PFS obtained with minimal toxicities and low costs induced us to setting up a randomized clinical trial.

Life for patients with myelofibrosis: the physical, emotional and financial impact, collected using narrative medicine-Results from the Italian 'Back to Life' project.

PURPOSE: Myelofibrosis (MF) is a chronic myeloproliferative neoplasm characterised by an aggressive clinical course, with disabling symptoms and reduced survival. Patients experience a severely impaired quality of life and their families face the upheaval of daily routines and high disease-related financial costs. The aim of this study was to investigate the perceptions of Italian patients and their caregivers about living with MF and the burden of illness associated with MF. METHODS: A quali-quantitative questionnaire and a prompted written narrative survey were administered to patients affected by primary or post-essential thrombocythemia/post-polycythaemia vera MF and their primary caregiver in 35 Italian haematological centres. RESULTS: In total, 287 questionnaires were returned by patients and 98 by caregivers, with 215 and 62, respectively, including the narrative. At the time of diagnosis, the most commonly expressed emotional states of patients were fear, distress and anger, confirming the difficulty of this phase. A high level of emotional distress was also reported by caregivers. Along the pathway of care, the ability to cope with the disease differed according to the quality of care received. The mean cost to each patient attributable to MF was estimated as €12,466 per year, with an estimated average annual cost of loss of income of €7774 per patient and €4692 per caregiver. CONCLUSIONS: Better understanding of the personal life of MF patients and their families could improve the relationships between health workers and patients, resulting in better focused healthcare pathways and more effective financial support to maintain patients in their social roles.

Ruxolitinib in clinical practice for primary and secondary myelofibrosis: an analysis of safety and efficacy of Gruppo Laziale of Ph-negative MPN.

Ruxolitinib, a JAK1 and JAK2 inhibitor, has been tested and approved for the treatment of primary and secondary myelofibrosis (MF). Aim of our study is to report safety and efficacy of ruxolitinib in 98 patients affected by MF treated outside clinical trials and collected and treated consecutively by the Lazio Cooperative Group for Ph negative myeloproliferative diseases.There were 45 males and 53 females; median age was 61.8 years (range 35.3-88). Forty-five patients were diagnosed as primary MF and 53 as secondary MF. Seventy-seven patients (78.5%) experienced constitutional symptoms at baseline, and out of 94 patients tested, 66 (70%) were JAK2V617F mutated. Overall, 40 patients received hydroxyurea as firstline treatment, 30 patients received other chemotherapeutic approaches, whereas 28 were treated with ruxolitinib frontline. Median time from diagnosis to start of ruxolitinib in the whole cohort was 34.6 months. Fifty-eight patients (59%) required a dose reduction during the first 3 months due to hematological toxicity in the majority of cases. At 48 weeks, 52% of patients obtained a clinical benefit: of them 7 patients (7%) had a CR, 10 (10%) a PR, 6 patients (6%) a CI, and 28 patients (28.5%) a spleen response. Overall, 66% of patients had disappearance of baseline symptoms burden. After 1 year, of 72 evaluable patients, 52% achieved and maintained a clinical benefit. Adverse events of special interest at any grade included anemia (39.7%), thrombocytopenia (25.5%), infections (16.3%, of which 10 were bronchopneumonia), fluid retention (3%), diarrhea (2%) and abdominal pain (2%). After a median follow-up of 16 months from start of ruxolitinib, median daily dose decreased to 10 mg BID and 21 patients (21%) discontinued the drug. The results of this retrospective multicentric analysis confirmed the efficacy of ruxolitinib outside clinical trials with more than half of treated patients achieving and maintaining a clinical benefit and most of them reporting relief from symptoms.

ITACA: A new validated international erythropoietic stimulating agent-response score that further refines the predictive power of previous scoring systems.

BACKGROUND: In 'real-life', the Nordic score guides Erythropoietic stimulating agent (ESA) use in lower-risk myelodysplastic syndrome (MDS) with predicted response rates of 25% or 74%. As new treatments emerge, a more discriminating score is needed. OBJECTIVES: To validate existing ESA predictive scores and develop a new score that identifies non-responders. METHODS: ESA-treated patients were identified in 3 MDS registries in Italy and Canada (FISM 555, GROM 233, and MDS-CAN 208). Clinical and disease-related variables were captured. Nordic, MDS-CAN, and IPSS-R-based ESA scores were calculated and documented ESA responses compared. RESULTS: 996 ESA-treated patients were identified. Overall response rate (ORR) was 59%. The database was randomly divided into balanced derivation (n = 463) and validation (n = 462) cohorts. By multivariate analysis, transfusion independence, erythropoietin (EPO) level <100 IU/L, and IPSS low-risk were independently predictive of response. Assigning a score of 1 to each resulted in a scoring system of 0-3 with response rates of 23%, 43%, 67%, and 85%. ORR was concordant in the validation cohort. The 'ITACA' score had the highest discriminating power of response. CONCLUSION: ITACA is an internally-validated predictive SS of ESA response in real-life 'good risk' MDS patients derived from a large international dataset that surpasses others. The incorporation of biologic markers to better identify non-responders is still needed.

Chelation efficacy and erythroid response during deferasirox treatment in patients with myeloproliferative neoplasms in fibrotic phase.

At present, very few data are available on deferasirox (DFX) in the treatment of patients with Philadelphia-negative myeloproliferative neoplasms in fibrotic phase (FP-MPN) and transfusion dependence. To address this issue, a retrospective analysis of 28 patients (22 male and 6 female) with FP-MPN and iron overload secondary to transfusion dependence was performed, based on patients enrolled in the database of our regional cooperative group who received treatment with DFX. DFX was started after a median interval from diagnosis of 12.8 months (IR 7.1-43.1) with median ferritin values of 1415 ng/mL (IR 1168-1768). Extra-hematological toxicity was reported in 16 of 28 patients (57.1%), but only two patients discontinued treatment due to toxicity. Among 26 patients evaluable for response (≥6 months of treatment), after a median treatment period of 15.4 months (IR 8.1-22.3), 11 patients (42.3%) achieved a stable and consistent reduction in ferritin levels <1000 ng/mL. As for hematological improvement, 6 of 26 patients (23%) showed a persistent (>3 months) rise of Hb levels >1.5 g/dL, with disappearance of transfusion dependence in four cases. Treatment with DFX is feasible and effective in FP-MPN with iron overload. Moreover, in this setting, an erythroid response can occur in a significant proportion of patients.

Spleen enlargement is a risk factor for thrombosis in essential thrombocythemia: Evaluation on 1,297 patients.

Spleen enlargement, present in 10-20% of Essential Thrombocythemia (ET) patients at diagnosis, is a feature clinically easy to assess, confirmable by echography with a very low chance of misinterpretation. Nonetheless, the clinical and prognostic role of splenomegaly has been seldom evaluated. From 1979 to 2013, 1297 ET patients retrospectively collected in the database of the Lazio Cooperative Group and Bologna University Hospital were evaluable for spleen enlargement at diagnosis and included in the analysis. On the whole, spleen was enlarged in 172/1297 (13.0%) patients; in most cases (94.8%) splenomegaly was mild (≤5 cm). Patients with splenomegaly were younger, predominantly male, presented higher platelet count and JAK2V617F allele burden and had a lower incidence of concomitant cardiovascular risk factors. At least one thrombotic event during follow-up occurred in 97/1,125 (8.6%) patients without spleen enlargement compared to 27/172 (15.7%) patients with spleen enlargement (P = 0.003). Despite comparable use of cytoreductive/antiplatelet therapies in the two groups, the cumulative risk of thrombosis at 5 years was significantly higher in patients with baseline splenomegaly (9.8% versus 4.4% in patients without splenomegaly, P = 0.012). In multivariate analysis exploring risk factors for thrombosis, splenomegaly retained its negative prognostic role, together with previous thrombosis, leucocyte count and male gender. Baseline splenomegaly seems to be an independent additional risk factor for thrombosis in nonstrictly WHO-defined ET patients. This data could be useful in the real-life clinical management of these patients.

Arterial and venous thrombosis in patients with monoclonal gammopathy of undetermined significance: incidence and risk factors in a cohort of 1491 patients.

Monoclonal gammopathy of undetermined significance (MGUS) has been associated with an increased risk of thrombosis. We carried out a retrospective multicentre cohort study on 1491 patients with MGUS. In 49 patients (3.3%) MGUS was diagnosed after a thrombotic event. Follow-up details for a period of at least 12 months after diagnosis of MGUS were obtained in 1238 patients who had no recent history of thrombosis (<2 years) prior to diagnosis, for a total of 7334 years. During the follow-up, 33 of 1238 patients (2.7%) experienced thrombosis, with an incidence of 2.5 arterial events and 1.9 venous events per 1000 patient-years. Multivariate analysis showed increased risks of arterial thrombosis in patients with cardiovascular risk factors [hazard ratio (HR) 4.92, 95%confidence interval (CI) 1.42-17.04], and of venous thrombosis in patients with a serum monoclonal (M)-protein level >16 g/l at diagnosis (HR 3.08, 95%CI 1.01-9.36). No thrombosis was recorded in patients who developed multiple myeloma (n = 50) or other neoplastic diseases (n = 21). The incidence of arterial or venous thrombosis in patients with MGUS did not increase relative to that reported in the general population for similarly aged members. Finally, the risk of venous thrombosis did increase when the M-protein concentration exceeded >16 g/l.

Risk factors for impaired gonadal function in female Hodgkin lymphoma survivors: final analysis of a retrospective multicenter joint study from Italian and Brazilian Institutions.

Hodgkin lymphoma (HL) is one of the most common types of cancer in the young and one of the most curable forms of cancer. Therefore, there has been an increasing interest in the study of long-term morbidities. The aims of the present study were to evaluate the prevalence and risk factors for impaired gonadal function in a retrospective cohort of 238 HL female survivors from Italy and Brazil and to analyse the role of oral contraceptives (OC) and GnRH-analogues. Besides data collection from HL databases, a specific questionnaire was administered to collect data on gonadal function. The median age at diagnosis was 25 years and the median follow-up was 7 years. Overall, 25% of the patients developed impaired gonadal function. Older age at diagnosis, front-line therapies containing alkylating agents and more than one treatment were independent risk factors, whereas the use of OC or GnRH-a reduced independently the risk of impaired gonadal function. The fertility rate among fertile survivors was low when compared with the general population. We confirmed that older age, type of front-line chemotherapy and a higher number of therapies are associated with gonadal function impairment in terms of infertility and premature menopause in female HL survivors. Also, the use of GnRH-a or OC was independently identified as a protective factor. Further prospective studies are needed to better understand the barriers to parenthood in HL survivors.

Immunotactoid glomerulopathy and chronic lymphocytic leukemia: The need for a multidisciplinary approach.

Chronic lymphocytic leukemia (CLL) is the most common type of leukemia in western countries. The association between CLL and glomerular disease (GD) is rare. The most frequent GD associated with CLL is membranoproliferative membranous glomerulonephritis (GN) (MPGN) (45%) types I and II, followed by membranous glomerulonephritis, with the same reports of immunotactoid glomerulopathy (ITG). We report a case of ITG diagnosed on kidney biopsy in a CLL patient and the response of renal parameters to drug treatment for CLL. The patient was treated with several lines of therapies with a good response.

Predictors of Response to Hydroxyurea and Switch to Ruxolitinib in HU-Resistant Polycythaemia VERA Patients: A Real-World PV-NET Study.

In polycythemia vera (PV), the prognostic relevance of an ELN-defined complete response (CR) to hydroxyurea (HU), the predictors of response, and patients' triggers for switching to ruxolitinib are uncertain. In a real-world analysis, we evaluated the predictors of response, their impact on the clinical outcomes of CR to HU, and the correlations between partial or no response (PR/NR) and a patient switching to ruxolitinib. Among 563 PV patients receiving HU for ≥12 months, 166 (29.5%) achieved CR, 264 achieved PR, and 133 achieved NR. In a multivariate analysis, the absence of splenomegaly (p = 0.03), pruritus (p = 0.002), and a median HU dose of ≥1 g/day (p < 0.001) remained associated with CR. Adverse events were more frequent with a median HU dose of ≥1 g/day. Overall, 283 PR/NR patients (71.3%) continued HU, and 114 switched to ruxolitinib. In the 449 patients receiving only HU, rates of thrombosis, hemorrhages, progression, and overall survival were comparable among the CR, PR, and NR groups. Many PV patients received underdosed HU, leading to lower CR and toxicity rates. In addition, many patients continued HU despite a PR/NR; however, splenomegaly and other symptoms were the main drivers of an early switch. Better HU management, standardization of the criteria for and timing of responses to HU, and adequate intervention in poor responders should be advised.

Symptomatic mucocutaneous toxicity of hydroxyurea in Philadelphia chromosome-negative myeloproliferative neoplasms: the Mister Hyde face of a safe drug.

BACKGROUND: The current study was conducted to evaluate severe mucocutaneous toxicity during treatment with hydroxyurea (HU) in a large cohort of patients with Philadelphia chromosome-negative myeloproliferative neoplasms (MPN). METHODS: Among 993 consecutive patients newly diagnosed with MPN at 4 centers in Rome between January 1980 and December 2009, 614 patients (277 men and 337 women with a median age of 64.4 years [interquartile range (IR), 54.4 years-72.7 years]) received HU. HU was administered as first-line treatment in 523 patients (85.2%) and as ≥ second-line treatment in 91 patients (14.8%). RESULTS: Mucocutaneous toxicity was reported in 51 patients (8.3%) after a median period from the initiation of HU treatment of 32.1 months (IR, 10.5 months-74.6 months) and a mean HU dose of 1085 mg (± 390 mg); 30 patients (58.8%) developed a painful ulcerative skin toxicity, mainly located in the perimalleolar area; 11 patients (21.6%) had oral aphthous ulcers; and 10 patients (19.6%) developed a nonulcerative skin toxicity with erythema and skin infiltration. After the mucocutaneous toxicity occurred, HU treatment was continued at the same dose in 5 patients (9.8%), reduced in 12 patients (23.5%), and temporarily discontinued in 7 patients (13.7%); the remaining 27 patients (52.9%) required a permanent drug discontinuation. After a median period of 4.3 months (IR, 2.4 months-9.0 months) from the onset of the skin toxicity, 39 patients (76.5%) had a complete resolution and 12 patients (23.5%) had improvement without complete resolution. CONCLUSIONS: Mucocutaneous toxicity during HU treatment is more common than expected and may present with different clinical features. Moreover, it often requires a permanent drug discontinuation and only a partial resolution is reported to occur in approximately 25% of patients.

Daratumumab combined with dexamethasone and lenalidomide or bortezomib in relapsed/refractory multiple myeloma (RRMM) patients: Report from the multiple myeloma GIMEMA Lazio group.

The multiple myeloma (MM) treatment has changed over the last years due to the introduction of novel drugs. Despite improvements in the MM outcome, MM remains an incurable disease. Daratumumab is a human IgGK monoclonal antibody targeting CD38 with tumor activity associated with immunomodulatory mechanism. In combination with standard of care regimens, including bortezomib (Vd) or lenalidomide (Rd), daratumumab prolonged progression-free survival (PFS) in patients (pts) with relapsed/refractory multiple myeloma (RRMM) and in new diagnosis MM. We report the data of the MM GIMEMA Lazio group in 171 heavily treated pts who received daratumumab, lenalidomide and dexamethasone (DRd) or daratumumab, velcade and dexamethasone (DVd). The overall response rate was 80%, and the overall survival (OS) and PFS were 84% and 77%, respectively. In addition, pts treated with DRd showed a better median PFS compared to pts treated with DVd, at 12 and 24 months, respectively. The most common hematologic treatment-emergent adverse events (TAEs) were neutropenia, thrombocytopenia, and anemia. The most common nonhematologic TAEs were peripheral sensory neuropathy and infections. Our data confirmed that DRd or DVd therapy is effective and safe in RRMM pts, and our real-life analysis could support the physicians regarding the choice of optimal therapy in this setting of pts.

Effects of Helicobacter pylori eradication on early stage gastric mucosa-associated lymphoid tissue lymphoma.

BACKGROUND & AIMS: Different remission rates of gastric low-grade, B-cell, mucosa-associated lymphoid tissue (MALT) lymphoma have been reported after Helicobacter pylori eradication. We assessed the long-term remission and relapse rates of early stage MALT lymphoma in patients treated only by H pylori eradication and identified factors that might predict outcome. METHODS: This systematic review analyzed data from 32 studies, including 1408 patients. RESULTS: The MALT lymphoma remission rate was 77.5% (95% confidence interval, 75.3-79.7), and was significantly higher in patients with stage I than stage II(1) lymphoma (78.4% vs 55.6%; P = .0003) and in Asian than in Western groups (84.1% vs 73.8%; P = .0001). Neoplasia confined to the submucosa regressed more frequently than that with deeper invasion (82.2% vs 54.5%; P = .0001); patients with lymphoma localized to the distal stomach experienced regression more frequently than those with lymphoma of the proximal stomach (91.8% vs 75.7%; P = .0037). The remission rate was higher among patients without the API2-MALT1 translocation than in those with this translocation (78% vs 22.2%; P = .0001). In an analysis of data from 994 patients, 7.2% experienced lymphoma relapse during 3253 patient-years of follow-up evaluation, with a yearly recurrence rate of 2.2%. Infection and lymphoma were cured by additional eradication therapy in all patients with H pylori recurrence (16.7%). Five (0.05%) of the patients initially cured of lymphoma developed high-grade lymphoma within 6 to 25 months of therapy. CONCLUSIONS: H pylori eradication is effective in treating approximately 75% of patients with early stage gastric lymphoma. Long-term follow-up evaluation of these patients is needed to detect early lymphoma relapse or progression.

Primary low-grade and high-grade gastric MALT-lymphoma presentation.

GOAL: To assess the clinical and endoscopic presentation of primary gastric lymphoma. BACKGROUND: Remission rate and long-term survival in patients with gastric lymphoma mainly depend on disease stage at diagnosis. Series reporting clinical and endoscopic presentation of gastric lymphoma are generally small and heterogeneous. STUDY: Systematic review with pooled-data analysis assessing clinical and endoscopic presentation of primary gastric lymphoma. RESULTS: Data regarding 2000 patients were collected. Overall, males were slightly more prevalent, alarm symptoms were absent in near half of the patients, lymphoma was diagnosed in a stage >I in one-third of the patients, and Helicobacter pylori infection was present in 88.8% of considered patients. At endoscopy, the ulcerative type was the most frequent presentation, although low-grade lymphoma was diagnosed on normal/hyperemic gastric mucosa in 9% of cases. Patients with high-grade lymphoma presented alarm symptoms (anemia and/or melena and/or hemorrhage, persistent vomiting, weight loss), an exophytic or ulcerative lesion, a stage III-IV, and a H. pylori negative status more frequently than low-grade lymphoma cases. CONCLUSIONS: Our pooled-data analysis showed that gastric lymphoma is still disappointingly diagnosed in an advanced stage in a large number of patients. This is probably due to presence of nonspecific symptoms at initial clinical presentation and/or a normal appearing mucosa at endoscopic observation in the early stages.

Front-Line Therapy for Elderly Chronic Lymphocytic Leukemia Patients: Bendamustine Plus Rituximab or Chlorambucil Plus Rituximab? Real-Life Retrospective Multicenter Study in the Lazio Region.

Previous studies investigated the efficacy and the safety of bendamustine (B) vs. chlorambucil (Chl) associated with rituximab (R) in fludarabine-ineligible patients with treated and untreated chronic lymphocytic leukemia (CLL). We conducted a retrospective multicenter study in the Lazio region to further evaluate and compare the efficacy and the toxicity of Chl-R and B-R regimen in CLL patients over the age of 65. We enrolled 192 untreated CLL patients: 111 treated with B-R and 81 with Chl-R. The overall response rates (ORR; 93.6% in B-R and 86.5% in Chl-R) were not statistically different between the two groups, such as progression-free survival (PFS), time to retreatment (TTR), and overall survival (OS). The B-R group showed a higher hematological (p = 0.007) and extra-hematological (p = 0.008) toxicity. When comparing the toxicities according to age, we noted that the extra-hematological toxicity was higher in patients over the age of 75 who were treated with B-R than those treated with Chl-R (p = 0.03). This retrospective study confirms the feasibility of B-R and Chl-R in elderly untreated CLL patients. Currently, patients who are over 75 and unfit are usually treated with Chl-R. This scheme allows achieving the same ORR, PFS, TTR, and OS when compared with B-R because of hematological and extra-hematological toxicities due to B, in which a greater dose reduction has been shown in comparison to Chl.
