This is a retrospective, multicentric study, aimed to describe the real-life application of fertility preservation methods during treatment in female lymphoma patients, aged 18-40 years old, diagnosed between Oct 1st/2010 and May 31st/2018. Among 414 women included, median age was 28 years old, histologies were: HL 74%, PMBCL 13%, DLBCL 10%, others 3%. First line treatments were: ABVD in 295 (71%), R-CHOP like in 102 (25%), higher intensity regimens in 17 (4%) cases. Fertility preservation strategies were: GnRHa in 315 (78%), Oral Contraceptive in 41 (10%), oocytes and ovarian tissue cryopreservation in 55 and 42 patients, respectively. After therapy, we observed a restored regular period in 293 (70%) and premature ovarian failure (POF) in 33 (8%), Furthermore we recorded 43 pregnancies, all spontaneous with 5 years median follow-up. Median age at diagnosis and number of lines of treatment correlate with higher rate of amenorrhea, risk of POF and menopause ( p  < 0.001).

We investigated panobinostat 40 mg three times weekly in 35 adult patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL). Overall response rate and complete response were 17.1% and 11.4%, respectively. Median progression-free survival (PFS) and overall survival were 2.4 and 7.6 months, respectively. Calculated 12, 24 and 36 months PFS were 26%, 11% and 11%, respectively. Four patients who achieved a sustained CR, continued receiving panobinostat for an overall period of 44, 48, 50, 62 months. Thrombocytopenia grade 3 (5 patients) and 4 (24 patients) represented the main toxic effect, causing dose reduction or treatment suspension in 19 patients. Genomic analysis was unable to identify any relationship between mutations and response; TP53 mutation appeared not to impact the clinical outcome. Overall, panobinostat has a modest activity in R/R DLBCL patients, however it can induce very long lasting responses in some cases. Thrombocytopenia frequently limits the use of this agent.

We examined real-world data on management of relapsed/refractory Hodgkin lymphoma (R/R HL) in five European countries and the consistency of these data with guideline recommendations. Retrospective clinical and epidemiologic data for 509 patients with R/R HL treated between January 2014 and March 2015 were collected at centers in France, Germany, Italy, Spain, and the United Kingdom. Mean age was 46.3 years; 73.3% were receiving second-line therapy for a first relapse during the reporting period. Most patients received ABVD as front-line chemotherapy, except in Germany where escalated BEACOPP was used more often. The proportion of patients receiving stem cell transplantation (SCT) was 44%; 85% of transplants occurred at first relapse. Brentuximab vedotin (BV) was usually administered after autologous SCT, and was initiated for 65% of patients following SCT failure. Our findings suggest that R/R HL management across these countries is broadly consistent with guideline recommendations and that BV is well-integrated into treatment pathways.

Patients with mantle cell lymphoma (MCL) usually respond to initial combination chemotherapy, but the disease inevitably relapses and often follows an aggressive course. Here, clinical study results published since 2008 for patients with relapsed/refractory MCL were reviewed to compare available evidence for treatment guidance. Most trials identified were non-randomized, phase II studies performed at a limited number of sites, and many evaluated MCL as one of multiple non-Hodgkin lymphoma subtypes. Additional randomized, comparative trials are needed. Treatment selection generally depends on patient need, age and fitness, time of relapse, and line of therapy. Combination regimens typically produce higher response rates than single agents, and adding rituximab generally improves outcomes. The inclusion of ibrutinib, lenalidomide, temsirolimus, and bortezomib, represents an important advance for patients ineligible for, unable to tolerate, or failing high-intensity combination chemotherapy. A high need for effective treatments in relapsed/refractory MCL remains, particularly for elderly and frail patients.

The activity and safety of a regimen combining lenalidomide with fludarabine and cyclophosphamide (FC) was investigated in patients with relapsed/refractory (R/R) chronic lymphocytic leukemia (CLL). Treatment consisted of six monthly courses of the FC regimen combined with 14 days of lenalidomide given at the starting dose of 2.5 mg during course 1. The maximum tolerated dose of lenalidomide was 5 mg. Forty patients were assessed for response, 66% were IGHV unmutated, 45% showed deletion 11q or 17p. The overall response and complete remission rates were 62.5% and 22.5%, respectively, the median progression-free and overall survival (OS) were 19 and 45 months, respectively. Grade 3-4 granulocytopenia was observed in 65% of cases, severe infections in 7.5%, the lenalidomide-related toxicity was mild. In conclusion, the results of this study demonstrate that low-dose lenalidomide associated with the FC schedule is an effective treatment for R/R patients with CLL, associated with an acceptable safety profile.

Clinical trial results indicate that lenalidomide, an immunomodulatory drug, is a promising treatment in relapsed/refractory non-Hodgkin lymphoma (NHL). This retrospective multicenter study was conducted in patients with relapsed/refractory NHL treated with lenalidomide monotherapy through a Named Patient Program in Italy. Principal endpoints were overall response rate (ORR), safety and overall survival (OS). The ORR in 64 evaluable patients was 42.2% and was similar among patients receiving 10, 15 or 25 mg/day lenalidomide. Response rates in patients with mantle cell, diffuse large B-cell and follicular lymphoma were 45.5%, 42.1% and 20%, respectively. Among patients who responded to most recent prior therapy, ORR was 50.0% versus 36.8% in patients with refractory NHL. Mean duration of response in patients receiving any lenalidomide dose was 10.5 months; 1-year progression-free survival and OS were 50.3% and 82.6%, respectively. These findings suggest that lenalidomide is effective and safe for heavily pretreated patients with NHL in the clinical setting.

According to the European Society for Medical Oncology and National Comprehensive Cancer Network guidelines on Waldenström macroglobulinemia, bendamustine (B) may be considered a suitable therapeutic option. To address the role of B in combination with rituximab (BR), we analyzed the outcome of 71 patients with relapsed/refractory disease, median age 72 years, treated with R 375 mg/m(2) day 1 and B days 1 and 2 (dosage ranging from 50 to 90 mg/m(2)). Patients had previously received a median number of 2 lines of treatment (range 1-5). Overall and major response rates were 80.2% and 74.6%. Major toxicity was grade 3/4 neutropenia occurring in 13% of courses. There was no significant association between baseline features or patients' characteristics and response achievement. Median progression-free survival was not reached after a median follow-up of 19 months (range 3-54). None of the patients developed aggressive lymphoma or secondary myelodysplastic syndrome/acute myeloid leukemia. BR was found to be an active and well-tolerated salvage regimen leading to rapid disease control.

Abstract Despite recent advances in therapeutic strategies, a large proportion of patients with mantle cell lymphoma (MCL) experience progression after first-line treatment. Several attempts have been made to assess the role of different therapies for the treatment of patients with relapsed/refractory mantle cell lymphoma; however, a consensus on the optimal therapeutic strategy for each individual patient has not been reached. Overall, clinical evidence from phase II studies shows that high-dose cytarabine containing regimens, stem cell transplant and different biological agents all have promising activity with acceptable safety profiles. Therefore, these therapies can represent suitable treatment options for patients with relapsed/refractory MCL. Among different biological agents, at present only temsirolimus has been tested in a phase III study. This review considers available evidence on the management of relapsed/refractory MCL as discussed during a consensus meeting on the current treatment strategies for MCL.

Mantle cell lymphoma (MCL) is a distinct subtype of malignant lymphoma characterized by the chromosomal translocation t(11;14)(q13;q32), resulting in constitutional overexpression of cyclin D1 and cell cycle dysregulation in virtually all cases. Clinically, MCL shows an aggressive clinical course with a continuous relapse pattern and a median survival of only 3-5 years. However, recently a subset of up to 15% long-term survivors has been identified with a rather indolent clinical course. Advanced stage disease is usually apparent already at first clinical manifestation; in general, conventional chemotherapy is only palliative and median duration of remissions is only 1-2 years. In 2000, the European MCL Network ( http://www.european-mcl.net ) was founded, which consists of 15 national lymphoma study groups supplemented by experts in hematopathology, cytogenetics and molecular genetics. During the last decade, the European consortium has successfully initiated the largest phase III trials in MCL worldwide. In the current study generation, the addition of high-dose Ara-C to a rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP)-like regimen followed by myeloablative consolidation achieved a significant improvement of progression-free survival. Similarly, in elderly patients, rituximab maintenance until progression led to a marked prolongation of remission duration. Emerging strategies include proteasome inhibitors, immune modulatory drugs (IMiDs), mammalian target of rapamycin (mTOR) inhibitors and others, all based on the dysregulated control of cell cycle machinery and impairment of several apoptotic pathways. Combination strategies are currently being investigated in numerous trials, but their introduction into clinical practice and current treatment algorithms remains a challenge. Future strategies will apply individualized approaches according to the molecular risk profile of the patient. At the annual conference in Warsaw, recent results of molecular pathogenesis, analyses of current clinical trials and new study concepts were discussed.

Young patients (aged 18-60 years) with good-prognosis diffuse large B-cell lymphoma (DLBCL) [0 and 1 risk factor according to age-adjusted international prognostic index (aa-IPI)] are distinguished from patients with poor-prognosis. Six cycles of cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) in combination with rituximab achieved best results in young patients with low-risk DLBCL. We retrospectively analyzed the data of 82 patients (18-60 years) with untreated aa-IPI 0-1 DLBCL, from six Italian institutions, who underwent, between January 2002 and January 2007, rituximab-cyclophosphamide, doxorubicin, vincristine, methotrexate, bleomicin and prednisone (R-MACOP-B) therapy followed, in patients with bulky presentation, by 30-36 Gy involved-field radiation therapy (34 patients). An overall response rate was noted in 77 out of 82 (94%) patients (75 patients had a complete response (91%), 2 patients had a partial response). With a median follow-up of 46 months, 7-year progression-free and overall survival were estimated to be 91% and 94%, respectively. R-MACOP-B regimen followed by involved-field radiation on bulky presentation is safe and very effective in the treatment of young patients with low-risk DLBCL.

Thirty untreated patients, median age 69 years (range 60 - 75 years), with diffuse large B-cell lymphoma (B-DLCL) were treated with a pegylated liposomal doxorubicin (PL-doxorubicin) modified CHOP-rituximab regimen. PL-doxorubicin 30 mg/m2, was given in combination with standard dosage of prednisone, vincristine, cyclophosphamide, rituximab (according to CHOP-R regimen) every 21 days for six courses. Cardiac toxicity was evaluated by mean of echocardiography for left ventricular ejection fraction (LVEF) evaluations and serum troponin-I levels. Overall response and complete response rates were 76% and 59%. Projected two year event free survival and overall survival are 65.5% and 68.5%. No treatment-related mortality was documented. WHO grade III-IV neutropenia and thrombocytopenia were 86% and 3%. Extra-hematological III-IV toxicity was represented, respectively, by a single case of infection, mucositis, and bleeding. LVEF evaluations and the troponin levels did not show significant changes over the course of the treatment. One patient with a previous history of atrial fibrillation experienced a single episode of arrhythmia. None of the patients developed palmar-plantar erythrodysesthesia. This regimen appears an active regimen for the treatment of elderly patients with B-DLCL. The replacement of conventional doxorubicin with PL-doxorubicin seems to be associated with a negligible incidence of extra-hematological toxicity, in particular cardiac and infectious complications.

Rituximab is active in chronic lymphocytic leukemia (CLL) and may interfere with autoantibodies production in some immune diseases. We report the results of rituximab treatment in 7 patients with CLL-associated symptomatic autoimmune diseases refractory to standard immunosuppressive therapies: warm antibody hemolytic anemia (AHA) 4 patients, cold agglutinin disease (CAD) 1, immune thrombocytopenia (IT) 1, axonal degenerating neuropathy (ADN) 1. Rituximab was given at the dose of 375 mg/m2 per week for 4 weeks. One patient with AHA and one with CAD achieved complete normalization of hemoglobin levels and laboratory signs of haemolysis, with response duration (RD) of 8+ and 38+ months, respectively. In the patient with IT, complete remission was reached after the first week of treatment and RD was 6 months. The patient with ADN achieved a marked neurological improvement after rituximab therapy, with RD of 12 months. Retreatment of both patients with IT and ADN was effective. Rituximab may be an alternative agent for the treatment CLL-associated autoimmune diseases.

The outcome of a series of adult patients, affected by primary systemic CD30-positive anaplastic large cell lymphoma (ALCL), treated with a sequential intensive therapeutic program, has been analyzed and all data available in the literature have been reviewed. Forty consecutive, unselected patients with ALCL were treated with the F-MACHOP regimen, followed by radiotherapy (RT) for residual mediastinal disease (15 cases) and by autologous stem cell transplantation (ASCT) conditioned with BAVC (29 cases). Eighty-nine percent (32/36) of the patients younger than 60 years were eligible for completing the sequential treatment. Since then, 3 patients in CR refused ASCT, 1 was excluded for cardiac toxicity and 3 progressed and died of disease. Thus, 29 have been so far submitted to the transplant procedure. CR and PR rates were 40% and 45% respectively after CHT; 52.5% and 35% after RT; 80% and 5% after ASCT, with 78% of patients transplanted in PR convertin to a CR. Actuarial overall survival is 85% at 48.5 months (93% at 66 months for the 29 transplanted patients) and disease free survival is 100% at 54 and 64 months respectively, with no relapses observed among patients who reached a CR. Considering our data and those of the literature, it can be concluded that although the role of ASCT in the therapy of ALCL must not be considered as definitive, its efficacy in converting PR into CR and in preventing relapses, suggests that a randomized trial comparing CHT alone vs CHT+ASCT should be undertaken.

Patients with a monoclonal gammapathy of undetermined significance (MGUS) are usually submitted to a periodical clinical follow-up, but it is not known if this surveillance can ameliorate the prognosis of a plasma cell malignancy that will be eventually detected. We compared the clinical and laboratory characteristics at onset, the response to chemotherapy and the survival, of 21 cases of newly diagnosed multiple myeloma (MM) arising from the malignant transformation of MGUS and 41 cases without a previous history of MGUS, recruited to the same first-line treatments over a 3-years period. The former group showed a significant lower frequency of advanced stages as well as other several prognostic factors of high risk including anemia, renal failure, bone lesions and increase of beta2 microglobulin and C-reactive protein levels. Despite a similar response to treatment of the two groups, MM arising from MGUS showed a significantly longer median survival than MM without prior MGUS. This was particularly true for stage I, while stages II and III behaved similarly. We conclude that the regular clinical monitoring of MGUS patients allowed the identification of earlier malignant transformation, when tumor burden is lower, as indicated by lower beta2 microglobulin levels and marrow plasmacytosis of stage I MM arising from MGUS. Moreover, a slower proliferation rate of myeloma cells, as suggested by lower C-reactive protein levels, may be considered so as to explain the longer survival of these patients.

Bcl-2 overexpression has been shown to be associated with several malignancies, including B-cell chronic lymphocytic leukemia (CLL) and non-Hodgkin's lymphomas (NHL), mainly low-grade and follicular in type. It has as yet not been described in hairy cell leukemia (HCL). In 30 patients with CLL and 14 with HCL who were consecutively selected for treatment with purine analogues (Fludarabine in CLL and 2-chloro-deoxy-adenosine in HCL), we evaluated bcl-2 oncoprotein expression in leukemic cells on marrow sections that were taken before treatment and stained immunohistochemically with a monoclonal antibody (Dakopatts 124 clone), by the avidin-biotin-peroxidase method. All samples were found to be bcl-2 positive, with a staining intensity that was moderate to strong in CLL and weak to moderate in HCL. 83% of CLL and 100% of HCL patients were responsive to purine analogues. These findings show that bcl-2 is overexpressed in almost all cases CLL and HCL and that bcl-2 overexpression does not predict a poor response to purine analogues, which are believed to induce apoptosis.

Most of the adult patients with primary systemic CD30 (Ki-1)-positive anaplastic large cell lymphoma (ALCL) reported in the literature have been treated with combination chemotherapy (CHT), with only an occasional patient being autotransplanted, mostly after relapse. Here we report a series of 19 patients treated at our Institution with a sequential intensive therapeutic program including CHT (the F-MACHOP regimen given for 6 cycles), radiotherapy (RT), and autologous stem cell transplantation (ASCT) after conditioning with the BAVC regimen. Eleven of 19 (58%) patients achieved a complete remission (CR) after CHT; 3 after RT and 4 after ASCT (1 patient is still not evaluable for response to ASCT). The actuarial overall survival is 100% at a median of 49 months from diagnosis and the actuarial disease free survival is 100% at a median of 41 months from the time CR was reached. These data suggest that ALCL can be successfully managed with a sequential intensive treatment that prevents early relapses and projects these patients as long-term survivors.

The aim of this study was to evaluate the role and potential benefit of G-CSF administered following standard regimen chemotherapy (CHT) in non-Hodgkin lymphomas. Twenty patients with NHL were given CHOP or CHOP/CVP CHT every 21 days. None was given G-CSF after the first cycle. After each cycle, G-CSF was administered only for: 1) ANC < 1 x 10(9)/L between cycles; or 2) delay in cycle schedule due to ANC < 1 x 10(9)/L on the planned day of treatment; or 3) development of a febrile syndrome or a documented infection, regardless the ANC. Once administered, G-CSF was maintained in the following cycles. Nineteen patients required administration of G-CSF (5 micrograms/Kg B.W.), but for different reasons only 16 were treated (a mean of 10 +/- 3 doses/cycle). Comparing 48 cycles where G-CSF was not administered, with 50 where it was, in this last group we observed: 1) a ANC significantly higher at day 7 (p < 0.0001), day 14 (p < 0.0001) and day 21 (p = 0.0030); 2) a significantly lower (p = 0.0001) incidence of neutropenias (6 vs 29); 3) a trend (p = 0.1040) in favour of lower incidence of febrile neutropenias of infections (1 vs 6); 4) a significantly lower (p < 0.0001) incidence of cycle delays (1 vs 22) with a median of 8 days (1 to 20); and 5) a significantly higher (p < 0.0001) dose intensity (99.5% vs 87.8%).(ABSTRACT TRUNCATED AT 250 WORDS)
