    Abstract: Background. Cardiac resynchronization therapy (CRT) is a treatment for heart failure (HF) patients with prolonged QRS and impaired left ventricular (LV) systolic function. We aim to evaluate how the baseline PR interval is associated with outcomes (all-cause death or HF hospitalizations) and LV reverse remodeling ( 〉 15% relative reduction in LV end-systolic volume). Methods. Among 2224 patients with CRT defibrillators, 1718 (77.2%) had a device programmed at out-of-the-box settings (sensed AV delay: 100 ms and paced AV delay: 130 ms). Results. In this cohort of 1718 patients (78.7% men, mean age 66 years, 71.6% in NYHA class III/IV, LVEF = 27 ± 6%), echocardiographic assessment at 6-month follow-up showed that LV reverse remodeling was not constant as a function of the PR interval; in detail, it occurred in 56.4% of all patients but was more frequent (76.6%) in patients with a PR interval of 160 ms. In a median follow-up of 20 months, the endpoint of death or HF hospitalizations occurred in 304/1718 (17.7%) patients; in the multivariable regression analysis it was significantly less frequent when the PR interval was between 150 and 170 ms (hazard ratio = 0.79, 95% confidence interval (CI): 0.63–0.99, p = 0.046). The same PR range was associated with higher probability of CRT response (odds ratio = 2.51, 95% CI: 1.41–4.47, p = 0.002). Conclusions. In a large population of CRT patients, with fixed AV pacing delays, specific PR intervals are associated with significant benefits in terms of LV reverse remodeling and lower morbidity. These observational data suggest the importance of optimizing pacing programming as a function of the PR interval to maximize CRT response and patient outcome.

    Abstract: BACKGROUND: The INTERIM study (ClinicalTrials.gov NCT 00858806) showed that in elderly ( 〉 65 years) Ph+ CML patients selected for a stable complete cytogenetic response (CCgR) lasting 〉 2 years, the policy of intermittent imatinib treatment (one month on/one month off) may affect the markers of residual disease (CCgR and major molecular response, MMR or MR3.0), but not the clinical outcomes (overall survival and progression-free survival) (Russo D et al, Blood 2013; 121(26):5138-44). AIMS: To update the results of the INTERIM Study, with a follow up ≥ 5 years. METHODS: After 4 years of follow up, patients continouing INTERIM treatment were monitored with peripheral blood RT-Q-PCR every 3 months according to the ELN-2013 guidelines. RESULTS: At 48thmonth, out of 76 patients enrolled in the INTERIM study, 13 (17%) had lost CCgR and MMR, 14 (18%) had lost MMR only and 50 patients (75%) continued INTERIM. The patients who had lost CCgR and/or MMR resumed imatinib continuously and all of them regained the CCgR and the MMR, within 3 to 12 months. No patient progressed to accelerated or blastic phase, or developed clonal chromosomal abnormalities in Ph+ cells, or BCR-ABL mutations. No patient complained of new or more severe side effects during the months “on”. After a follow up ≥ 5 years, 45/76 (59%) enrolled patients are on INTERIM, with a probability of maintaining intermittent administration of 59% (95% CI: 46-69). No patient lost the CCgR and only 9 additional patients lost the MMR while on intermittent treatment. All these patients resumed continuous imatinib treatment and regained the MMR. Thus, at ≥ 5 years, the probability of maintaing CCgR is 80% (95% CI 68-87) and the probability of maintaining the MMR is 61% (95% CI: 48-71). From start of INTERIM, 6 patients died but no deaths were related to CML progression (3 cases of other non haematological neoplasms, 1 stroke, 1 myocardial infarction, 1 chronic obstructive pulmonary disease).The PFS at ≥ 5 years is 94% (95% CI: 89-100) CONCLUSIONS: In summary, with a follow up ≥ 5 years, intermittent imatinib administration (INTERIM) confirmed to be safe, to produce a reversible increase of residual molecular disease in about one third of patients, but not to affect the long-term outcome.

    Abstract: Abstract 3412 The phase II explorative study of intermittent Imatinib (IM) treatment (InterIM) in elderly patients with Ph + chronic myeloid Leukemia (CML) who achieved a stable complete cytogenetic response (CCgR) after at least 2-years standard IM therapy (any dose between 300 and 800 mg/day) was started in April 2008 and closed for the enrollment in August 2009, since more than 78 patients required by statistics were included into the study. The main objective of the study was to investigate if after 12 months (trial time) the CCgR achieved with standard (daily administration) IM therapy could be maintained with InterIM. For this purpose, the CgR status was assessed by Interphase Fluorescence In Situ Hybridization (I-FISH) on peripheral blood (≥ 200 cells counted) every 3 months. When I-FISH (% Ph + nuclei) increased more then 1%, chromosome banding analysis (CBA) on bone marrow was performed to confirm the loss of CCgR and to check for additional cytogenetic abnormalities (ACA). At the present time, out of the 95 patients who were enrolled, 82 patients were evaluable and out of them 77 (94%), 73 (89%), 71 (87%) and 70 (85%) completed 3, 6, 9 and 12 months of the treatment program, respectively. Therefore, the great majority of patients completed the study core and at the end of 2010 all the patients are expected to complete the trial time (12 mo). During the first 12 months of InterIM, 1% to 11% of the evaluable patients at 3, 6, 9 and 12 months showed an I-FISH 〉 1% Ph+ nuclei (Figure 1). Figure 1 Distribution of patients according to I-FISH Figure 1. Distribution of patients according to I-FISH Totally, eleven (13%) out of 82 patients treated with InterIM showed an I-FISH 〉 1% and they were checked by CBA on bone marrow (Figure 2). Out of them only 3 cases, that means 4% of the 82 evaluable patients, lost the CCgR and resumed standard IM therapy (daily administration), but none completed 3 months of therapy. All the patients lost the MMR and increased several folds the BCR-ABL transcript levels. Two pts had a low risk Sokal and one a high risk; age was 66, 69, 77 years; time from diagnosis was 29, 91 and 100 months; duration of IM therapy was 29, 83 and 84 months; the IM dose was 400mg in all cases. Figure 2 Cytogenetic and molecular response in 11 cases who showed I-FISH 〉 1% + nuclei and who were checked by CBA on bone marrow. Black boxes shows the 3 cases who lost the CCgR Figure 2. Cytogenetic and molecular response in 11 cases who showed I-FISH 〉 1% + nuclei and who were checked by CBA on bone marrow. Black boxes shows the 3 cases who lost the CCgR As concern as molecular response, 99% of the patients had a major molecular response (MMR= 〈 0.001-0.1 BCR-ABL/ABLISX 100) at the baseline. The proportion of the patients who maintained the MMR after 3, 6, 9 and 12 months of InterIM was 95%, 92%, 91%, 84%, respectively. Interestingly, we found a weak but significant correlation between the % of BCR-ABL + nuclei and the BCR-ABL transcript levels in the patients who completed the trial time (12 mo) (r=0.27; p=0.001). In conclusion, the results of the InterIM study core (12 months), clearly show that Intermittent Imatinib (IM) treatment (InterIM) is sufficient to maintain the complete cytogenetic response (CCgR) previously achieved with standard IM therapy in elderly (≥ 65 years) Ph+ CML patients. The risk to loose the CCgR has been very low (4%), while the benefit either in terms of reduction of IM dose and of costs of therapy or in terms of compliance (data not shown) was very high.

    Abstract: Abstract 860 Background: Elderly CML patients treated with Imatinib (IM) in early chronic phase (CP) have similar cytogenetic response and survival compared with younger patients, but they show a lower compliance to standard IM therapy (400 mg/day). Aims: The aim of the study is to investigate if CCgR that has been achieved with standard (daily administration) IM therapy can be maintained with the same dose of IM given intermittently (INTERIM). Methods: The study population is represented by elderly patients (≥ 65 years old) with Ph+ CML and with stable CCgR after at least 2 years of standard IM therapy (daily administration). IM is given at the same dose that was given at the time of enrollment by the following intermittent schedule: 1 week on / 1 week off for the 1st month; 2 weeks on / 2 weeks off for the 2nd and 3rd month; 1 month on / 1 month off from the 4th month thereafter. In cases of loss of CCgR INTERIM was stopped and standard therapy (daily administration) was resumed. After 12 months, the patients who are in continuous CCgR are advised to continue the intermittent study schedule and to be followed indefinitely. The CgR status was evaluated at baseline (by conventional cytogenetics on bone marrow and FISH on peripheral-blood) and every 3 months during the study (only by FISH on peripheral-blood). If FISH (% of Ph+ cells) increased more than 1% in two consecutive examinations, evaluation of marrow cells metaphases was performed to confirm the loss of CCgR and to check for additional cytogenetic abnormalities. Quantitative molecular assessment of BCR-ABL transcript by RQ-PCR on peripheral blood was due at baseline and every 3 months during the study and mutational analysis of ABL was performed in case of loss of CCgR. Results: One-hundred and fourteen patients have been considered eligible, but 17 (15%) refused to enter into the protocol. Out of 97 enrolled patients, 87 started INTERIM, 5 patients (5%) went off the study for major protocol violation before the 3rd month and, at present, 82 patients are ongoing. Of these 82 patients, 52, 30 and 11 completed the 3rd, 6th and 9th month, respectively. The preliminary results of the first 6 months are here reported. The distribution of patients according to FISH results is shown in Fig. 1. Only 1/68 pts (at 6th month) showed an increased 〉 1% in Ph+ cells by FISH but he maintained a CCgR when checked by conventional cytogenetic. As showed in Fig. 2, 96 to 87% of patients maintained a major molecular response MMR (≤0,1) according to International Scale (IS). Conclusions: This study is trying to test the minimum effective dose of Imatinib to maintain the CCgR in elderly CML patients with stable CCgR. The preliminary results at 6 months do not show negative trends both for cytogenetic and molecular response. Therefore, the study is ongoing and all patients are expected to complete the trial time (12 months). Disclosures: No relevant conflicts of interest to declare.

    Abstract: The aim of this research was to evaluate if patients with chronic kidney disease (CKD) and mild or mild to moderate depression of renal function have an increased risk of atrial fibrillation (AF) recurrences after cryoballoon (CB) ablation. We performed a retrospective analysis of AF patients undergoing pulmonary vein isolation (PVI) by CB. The cohort was divided according to the KDIGO CKD-EPI classification into a (1) normal, (2) mildly decreased, or (3) mild to moderate reduction in estimated glomerular filtration rate (eGFR). Freedom from AF recurrences was the primary endpoint. A total of 1971 patients were included (60 ± 10 years, 29.0% females, 73.6% paroxysmal AF) in the study. Acute success and complication rates were 99.2% and 3.7%, respectively, with no significant differences among the three groups. After a follow-up of 24 months, AF recurrences were higher in the mildly and mild to moderate CKD groups compared to the normal kidney function group (23.4% vs. 28.3% vs. 33.5%, p 〈 0.05). Mild to moderate CKD was an independent predictor of AF recurrences after the blanking period (hazard ratio:1.38, 95% CI 1.02–1.86, p = 0.037). In conclusion, a multicenter analysis of AF patients treated with cryoablation revealed mild to moderate reductions in renal functions were associated with a higher risk of AF recurrences. Conversely, the procedural success and complication rates were similar in patients with normal, mildly reduced, or mild to moderate reduction in eGFR.

    Abstract: Abstract 1682 Background: The introduction of Imatinib has significantly improved the outcome for patients with Ph+ CML. The complete cytogenetic response (CCgR) is a strong and confirmed predictor of improved long-term outcome. According to current recommendations, Imatinib (IM) should be continued indefinitely. However, optimal responders can be eligible for investigational trials of treatment discontinuation. AIMS: This study (ClinicalTrials.gov NCT 00858806) describes the effects of a policy of intermittent Imatinib (INTERIM) treatment (one month on/one month off) on cytogenetic and molecular responses in a selected population of patients ≥ 65 years old who were receiving treatment with Imatinib for 〉 2 years and were in stable complete cytogenetic response (CCgR). The primary endpoint of the study was the proportion of patients who maintained CCgR after 1 year of INTERIM. The secondary endpoint was the level of BCR-ABL transcripts during INTERIM METHODS: Cytogenetic and molecular responses were monitored by FISH and RT-Q-PCR every 3 months. The definition of CCgR, and of CCgR loss was based on CBA of marrow metaphases which was performed at baseline and in all the patients who became FISH positive (BCR-ABL–positive nuclei 〉 1%). Major molecular response (MMR), corresponding to a 3-log reduction in BCR-ABL transcript level from the standardized baseline, was defined as BCR-ABL ≤0.1%IS and was indicated as MR3.0. For the purposes of this study, complete molecular response (CMR) was defined as a 4-log reduction in BCR-ABL transcript level ( 〈 0.01%IS), with a sensitivity of at least 10,000 ABL copies, and is indicated as MR4.0. In case of loss of CCgR or MMR, Ph+ additional cytogenetic abnormalities (ACA) and BCR-ABL kinase domain (KD) point mutation analysis were also performed. RESULTS: Seventy-six patients have been enrolled. Six patients (8%) lost CCgR (CBA positive), and 3 other patients became FISH positive while remaining CBA negative. At 12 months, the probability of maintaining CBA negativity was 92% (95% CI 86–98%), while the probability of maintaining FISH negativity was 87% (95% CI 79–94%). None of the factors that were examined by univariate and multivariate analysis were found to be associated with an higher probability of either loosing the CCgR (CBA) or showing a FISH positivity ( 〉 1%), with the exception of the duration of imatinib therapy (HR = 0.23, 95% CI 0.008–0.73, P =.01). Among patients with prior Imatinib treatment longer or shorter than 48 months, the probability of maintaining FISH negativity was 94% (95% CI 88–100%) vs 71% (95% CI 53–89%), respectively, HR = 0.23 (P =.007). All the 6 patients who lost CCgR regained the CCgR with daily Imatinib, at the same dose, defined by FISH negativity after 3 to 9 months (4/6 also CBA negative, 2 patients refused bone marrow aspiration). At baseline, all but one patient (99%) were in MMR (MR3.0, BCR-ABL ≤0.1%IS), and 63 patients (83%) were in MR4.0 ( 〈 0.01%IS). After one year of intermittent Imatinib, 18/76 patients (24%) lost MR3.0 and 25/63 (39%) patients lost MR4.0. No patient lost complete hematologic response, progressed to accelerated or blastic phase, developed ACA in Ph+ cells, or developed BCR-ABL mutations. After one year, the remaining 70 patients were allowed to go back to continuous treatment, or to continue the intermittent treatment. During the first six months of follow-up (month 13 to 18), 1 of 70 discontinued Imatinib for atrial fibrillation and 9 of 70 went back to continuous treatment because FISH negativity loss (1 patient) or MMR (MR3.0) loss (8 patients). All the patients continue to be regularly observed and monitored and the first twelve months of follow-up will be presented. CONCLUSIONS: The intermittent use of imatinib in older patients in stable CCgR after continuous imatinib treatment results in the transient loss of the CCgR in a minority (8%) of the patients. However, the disease burden at the molecular level significantly increased. A policy of intermittent treatment may be an alternative both to chronic continuous treatment and to treatment discontinuation, particularly in the elderly. However, a longer follow up is required before drawing final conclusions.

    Abstract: The FOLL05 trial compared R-CVP (rituximab plus cyclophosphamide, vincristine, and prednisone) with R-CHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone) and R-FM (rituximab plus fludarabine and mitoxantrone) regimens without rituximab maintenance as initial therapy for patients with advanced-stage follicular lymphoma (FL). A previous analysis with a median follow-up of 34 months showed a superior 3-year time to treatment failure, the primary study end point, with R-CHOP and R-FM versus R-CVP and showed R-CHOP to have a better risk-benefit ratio in terms of toxicity than R-FM. We report a post hoc analysis of this trial after a median follow-up of 7 years. Patients and Methods Of the 534 enrolled patients, 504 were evaluable. At the time of analysis, the median follow-up was 84 months (range, 1 to 119 months). Results The 8-year time to treatment failure and progression-free survival rates were 44% (95% CI, 39% to 49%) and 48% (95% CI, 43% to 53%), respectively. The hazard ratio for progression-free survival adjusted by FL International Prognostic Index 2 versus R-CVP was 0.73 for R-CHOP (95% CI, 0.54 to 0.98; P = .037) and 0.67 for R-FM (95% CI, 0.50 to 0.91; P = .009). The 8-year overall survival (OS) rate was 83% (95% CI, 79% to 87%), with no significant differences among study arms. Overall, we observed a higher risk of dying as a result of causes unrelated to lymphoma progression with R-FM versus R-CVP. Conclusion With an 83% 8-year OS rate, long-term follow-up of the FOLL05 trial confirms the favorable outcome of patients with advanced-stage FL treated with immunochemotherapy. The three study arms had similar OS but different activity and toxicity profiles. Patients initially treated with R-CVP had a higher risk of lymphoma progression compared with those receiving R-CHOP, as well as a higher risk of requiring additional therapy.

    Abstract: There is no consensus on the optimal systemic treatment of patients with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue. The IELSG-19 phase III study, to our knowledge, was the first such study to address the question of first-line treatment in a randomized trial. Patients and Methods Eligible patients were initially randomly assigned (1:1 ratio) to receive either chlorambucil monotherapy (6 mg/m 2 /d orally on weeks 1 to 6, 9 to 10, 13 to 14, 17 to 18, and 21 to 22) or a combination of chlorambucil (same schedule as above) and rituximab (375 mg/m 2 intravenously on day 1 of weeks 1, 2, 3, 4, 9, 13, 17, and 21). After the planned enrollment of 252 patients, the protocol was amended to continue with a three-arm design (1:1:6 ratio), with a new arm that included rituximab alone (same schedule as the combination arm) and with a final sample size of 454 patients. The main end point was event-free survival (EFS). Analysis of chlorambucil versus the combination arm was performed and reported separately before any analysis of the third arm. Results At a median follow-up of 7.4 years, addition of rituximab to chlorambucil led to significantly better EFS (hazard ratio, 0.54; 95% CI, 0.38 to 0.77). EFS at 5 years was 51% (95% CI, 42 to 60) with chlorambucil alone, 50% (95% CI, 42 to 59) with rituximab alone, and 68% (95% CI, 60 to 76) with the combination ( P = .0009). Progression-free survival was also significantly better with the combination ( P = .0119). Five-year overall survival was approximately 90% in each arm. All treatments were well tolerated. No unexpected toxicities were recorded. Conclusion Rituximab in combination with chlorambucil demonstrated superior efficacy in mucosa-associated lymphoid tissue lymphoma; however, improvements in EFS and progression-free survival did not translate into longer overall survival.

    Abstract: The aim of the F2 study was to verify whether a prospective collection of data would enable the development of a more accurate prognostic index for follicular lymphoma (FL) by using parameters which could not be retrospectively studied before, and by choosing progression-free survival (PFS) as principal end point. Patients and Methods Between January 2003 and May 2005, 1,093 patients with a newly diagnosed FL were registered and 942 individuals receiving antilymphoma therapy were selected as the study population. The variables we used for score definition were selected by means of bootstrap resampling procedures on 832 patients with complete data. Procedures to select the model that would minimize errors were also performed. Results After a median follow-up of 38 months, 261 events for PFS evaluation were recorded. β2-microglobulin higher than the upper limit of normal, longest diameter of the largest involved node longer than 6 cm, bone marrow involvement, hemoglobin level lower than 12 g/dL, and age older than 60 years were factors independently predictive for PFS. Using these variables, a prognostic model was devised to identify three groups at different levels of risk. The 3-year PFS rate was 91%, 69%, and 51% for patients at low, intermediate, and high risk, respectively (log-rank = 64.6; P 〈 .00001). The 3-year survival rate was 99%, 96%, and 84% for patients at low, intermediate, and high risk, respectively (P 〈 .0001). Conclusion Follicular Lymphoma International Prognostic Index 2 is a simple prognostic index based on easily available clinical data and may represent a promising new tool for the identification of patients with FL at different risk in the era of immunochemotherapy.
