Abstract The aim of this study was to evaluate long-term outcome of acute myeloid leukemia (AML) patients treated within the PALG 1999 DAC vs. DA Study. [b][Within 3 years (1999–2002) 445 patients, aged 18–60, were randomized 1:1 to the induction treatment DAC-7: daunorubicin 60 mg/m2/d iv 1–3; cytarabine 200 mg/m2/d ci d 1–7; cladribine (2-CdA) 5 mg/m2 2h inf. iv d 1–5 and standard DA-7 regimen (the same therapy excluding cladribine). Patients achieving CR received two courses of subsequent intensive consolidation: HAM (HD AraC, mitoxantrone) HD AraC with or without cladribine in the DAC-7 or DA-7 arm, respectively. In case of PR after the first induction course the same regimen was repeated, Post-consolidation therapy was comparable in both arms with following proportions of autoHCT, alloHCT and maintenance: DAC-7 17%, 14%, 69%; DA-7 21%, 14%, 65%, respectively. As previously reported, a single course of DAC-7 induction resulted in 17% higher CR rate compared to the DA-7 treatment (p=0,0008). The difference was particularly pronounced in patients: aged >40 years and with initial WBC >100x109/L. In the latter subgroup also the overall CR rate (achieved after entire induction program) was higher in the DAC-7 arm (71% vs. 43%). [Leukemia.2004;18:989–97] In the present report we analyzed seven-year long-term outcome (median follow-up 5 yrs) in the whole study population and in subgroups stratified according to age, initial WBC, cytogenetics, sex, FAB subtype, and preceding myelodysplasia. In the whole group the overall survival (OS) rate equaled 29,5% for DAC-7 and 24% for DA-7 arm (p=NS) and leukemia free survivall (LFS) 30% vs. 28% (p=NS), respectively. Of note, in patients aged >40 years, the therapy containing cladribine was associated with improved OS (26% vs. 14,5%, p=0.03), and LFS (28% for DAC-7 vs. 18,5% for DA-7, p=0.02). Other subgroup analyses revealed higher probability of the OS in patients with initial WBC ≥ 50 G/l assigned to DAC-7 compared to DA-7 arm (32% vs. 20,5%, p=0.04). The LFS rate equaled 35% and 27% (p=NS), respectively. In women receiving DAC-7 induction therapy in comparison with those treated in arm without 2-CdA reached higher OS: 29% vs. 19,5%, p=0,03, respectively. LFS in these subgroups was comparable: 25% vs. 22%, p=NS, respectively. We conclude that addition of cladribine to induction and consolidation therapy of AML improves long-term outcome in patients: older than 40 y, as well as in those with high tumour burden. The better outcome in older patients results mainly from reduced risk of relapse, whether that in cases with high WBC seems to be linked to a higher CR rate.

Abstract The goal of the study was to evaluate long-term outcome of acute myeloid leukemia (AML) patients treated within the PALG 1999 DAC vs, DA Study. Between 1999–2002, 445 patients, aged 18–60 years, were randomized to the induction DAC-7: daunorubicin 60 mg/m2/d iv 1–3; cytarabine 200 mg/m2/d ci 1–7; cladribine 5 mg/m2 2h inf. iv d 1–5 or standard DA-7 regimen (the same regimen without cladribine). Patients achieving CR received two courses of subsequent intensive consolidation: 1) HAM (HD AraC, mitoxantrone) 2) HD AraC with or without cladribine in the DAC-7 or DA-7 arm, respectively. In case of PR after the first induction course the same regimen was repeated, NR patients received CLAG (2-CDA, HD-AraC, G-CSF), regardless the randomization arm. Post-consolidation therapy was in both arms comparable. As previously reported, a single course of DAC-7 induction resulted in 17% higher CR rate compared to the DA-7 treatment. The difference was particularly pronounced in a population of patients >40 years and for those with initial WBC >100x109/L. In the latter subgroup also the overall CR rate (achieved after >=1 induction course) was higher in the DAC-7 arm (71% vs. 43%). [Leukemia. 2004 May;18(5):989–97] In the present report we analyzed long-term outcome (median follow-up 3.2 years) in the whole study group and in pre-defined subgroups taking into account initial tumor burden, age, cytogenetics, FAB subtype, and preceding myelodysplasia. At five years the overall survival (OS) rate equaled 31% for DAC-7 and 25% for DA-7 arm (p=0.42) and leukemia free survivall (LFS) 32% vs. 29% (p=0.38), respectively. The subgroup analysis revealed higher probability of the OS in patients with initial WBC ≥100 G/l assigned to DAC-7 compared to DA-7 arm (39% vs. 11%, p=0.02). The LFS rate and the probability of relapse equaled 50% and 32% (p=NS) and 36% and 68% (p=0.0497), respectively. In patients aged >40 years, the therapy containing cladribine was associated with improved LFS (30% for DAC-7 vs. 20% for DA-7, p=0.01), and a tendency to improved OS (28% vs. 18%, p=0.09). In this subgroup DAC-7 therapy resulted in reduced relapse incidence (60% vs. 69%, p=0.04).We conclude that addition of cladribine to induction/consolidation therapy of AML may improve long-term outcome in higher age ranges patients and in those with high tumor burden. The improvement results mainly from reduced risk of relapse, and, in patients with high initial WBC, from higher CR rate.

Abstract Introduction The discovery of the NPM mutation in acute myeloid leukemia (AML) allowed to identify a distinct entity with intermediate-good prognosis particularly when the FLT3/ITD mutation is absent. The most appropriate consolidation treatment of these patients upon the achievement of the first complete remission has not been established yet and the role of allogeneic stem cell transplantation (SCT) is still debated. Aim to assess long-term outcome of adult patients with NPM positive acute myeloid leukemia according to type and intensity of consolidation therapy. Patients and methods Between May 2000 and February 2012, 1155 patients were enrolled into two consecutive, prospective Northern Italy Leukemia Group (NILG) trials (00/01 and 02/06). Six-hundred sixty nine were studied for NPM mutation and 218 (33%) proved positive (by immunohistochemistry or by molecular analysis) (Falini et al, Haematologica. 2007 Apr;92(4):519-32). Median age of NPM+ patients was 50 years (range 16-72) and 134 (61%) were female. Median WBC was 33.3 x 10^9/L (range 0.9-313.9), 71 (33%) had myelomonocytic leukemia (FAB M4), and 211 (96%) had de novo AML. According to the European Leukemia Net (ELN) classification, cytogenetic risk groups were: normal 178 (82%), intermediate 26 (12%), unfavorable 2 (1%) and unknown 12 (5%). Eighty-two (38%) patients had a concurrent FLT3/ITD mutation and 31 (14%) a FLT3/TKD mutation. According to cytogenetics and additional risk factors (late response, WBC count >50x10^9/L, FAB class M0/6/7, hepato/splenomegaly, MDS-related/secondary AML, FLT3/ITD mutation), patients were stratified in standard (SR) and high (HR) risk groups. In both studies the remission induction was based on combination of cytarabine with idarubicin. Post-remission therapy was allogeneic SCT in HR while high-dose cytarabine or busulfan/cyclophosphamide with autologous SCT was given to SR patients. The molecular evaluation of minimal residual disease (MRD) was planned after induction, before the post-remission consolidation and the follow-up. Results Complete remission (CR) was achieved in 196/218 (90%) NPM+ patients. One hundred sixty-eight out of 196 remitters (86%) received post-remission consolidation therapy: allogeneic SCT 72 (37%), high dose Ara-C 74 (38%), autologous SCT 14 (7%), other therapy 8 (4%); 28 patients did not receive consolidation due to early relapse (n=24), CR death (n=3), and loss to follow-up (n=1). With a median follow-up of 1.8 years (range 0.008-12.66), 99 CR patients (50.5%) were alive in 1st CR, 13 (6.5%) died of complications, and 84 (43%) had recurrent AML. In a cumulative analysis, 5-year overall and disease-free survival were 46% (OS) and 43% (DFS), respectively. In univariate analysis FLT3/ITD mutation (n=82) affected negatively 5-year OS (29% vs. 49%, P < .0001) and DFS (27% vs. 46%, P < .0001), whereas FLT3/TDK mutation did not. In patients with FLT3/ITD mutation able to receive consolidation therapy (n=49), the application of allogeneic SCT improved DFS significantly (55% vs. 18%, P = .03) and reduced the cumulative incidence of relapse (CIR) (39% vs. 81%, P = .026). In patients with NPM+ and FLT3/ITD- AML, the risk of relapse after high dose cytarabine or autologous SCT (n=68) was more than doubled compared to that observed after allogeneic SCT (n=42) (50% vs. 23%, P= .08) (Figure). However, DFS (48% vs. 69.5%, p= .17), and OS (60% vs. 72%, p= .80) were not significantly different since allogeneic SCT was associated with higher treatment related mortality, albeit effective in the salvage of some relapsed patients. In multivariate analysis, FLT3/ITD mutation was the most powerful factor that unfavorably affected OS, DFS and CIR, while age > 55 years negatively affected OS and DFS. No other clinical factor was predictive for relapse in FLT3- patients. The relationship between MRD and clinical outcome is currently being studied and will be presented. Conclusions Our data indicate that allogeneic SCT is the most active post-remission treatment for NPM+ AML, but its benefit over chemotherapy may be limited in patients without FLT3/ITD. For this reason the evaluation of MRD could help identify the patients for whom an allogeneic SCT should be preferable. Disclosures: No relevant conflicts of interest to declare.

Abstract Abstract 1866 Background: In multiple myeloma (MM), the association between the response to induction before autologous stem cell transplantation (ASCT) and long-term outcome is less clear but the situation may change with the introduction of novel agents. We therefore assessed the clinical relevance of response of bortezomib induction treatment or post-ASCT response for patients who received bortezomib-combined induction chemotherapy followed by ASCT. Methods: We retrospectively assessed 183 MM patients who received bortezomib-containing induction therapy (BTZ-IT) followed by ASCT in 24 institutions throughout Korea between 2003 and 2010. Records of these patients were reviewed using the Korean Myeloma Registry database (www.myeloma.or.kr). Each institution was requested to reconfirm the data using additional case report forms. Patients who had overt MM based on International Myeloma Working Group diagnostic criteria were selected. Results: One-hundred seventy eight patients were eligible. Their median age was 56 years (range, 28–69 years) and 96 (53.9%) were male. Forty nine (27.5%) received bortezomib as front-line therapy and 129 (72.5%) as second-line treatment. All patients underwent ASCT and 22 (12.4%) were treated with tandem ASCT. Ninety-seven (54.5%) patients were treated with maintenance therapy after ASCT. After BTZ-IT, the response rates in this selected series of patients were 37.6% CR, 12.4% VGPR, 41.0% PR, 7.3% SD and 1.7% PD (Figure 1A, 1B, 1C); the corresponding post-ASCT rates were 69.2% CR, 14.0% VGPR, 11.0% PR, 2.9% SD and 2.9% PD. At a median follow-up of 46.6 months, the 3-year overall survival (OS) and event-free survival (EFS) rates were 70.0% and 31.9%, respectively. Multivariate analysis showed that factors independently predictive of OS and EFS included achievement of BTZ-IT response °Ã PR (P=0.025 and P=0.014, respectively) and the treatment with maintenance therapy (P=0.048 and P=0.001, respectively). Post-ASCT CR vs. °Â VGPR was also an independent prognostic factor for OS and EFS (P=0.0001 and P=0.002, respectively). Conclusion: At least PR to BTZ-IT and CR after ASCT were predictive of survival. These findings suggest that patients who responded to BTZ-IT may benefit from ASCT due to an enhanced quality of response. Maintenance therapy can also affect patient outcomes. Disclosures: No relevant conflicts of interest to declare.

Abstract Background. In 2005 we analyzed the results of a prospective randomized phase III intergroup trial evaluating the role of rituximab (R) both in remission induction and maintenance treatment of 465 relapsed/resistant follicular lymphoma (FL) patients. Major conclusions were that addition of R to CHOP induction yielded an increased ORR and CR rate, and that R maintenance strongly improved median progression free survival (PFS), both after induction with CHOP and R-CHOP, and overall survival (OS (van Oers et al Blood2006;108:3295). At that time the median follow for the maintenance phase was 33 months. Now we report the long-term outcome of maintenance treatment, with a median follow up of 6 years from start of maintenance. Study design. Patients with stages III or IV FL at initial diagnosis and relapsed after or resistant to a maximum of two non-anthracycline containing systemic chemotherapy regimens, were randomized to remission induction with either 6 cycles of standard CHOP (once every 3 weeks) or CHOP + R (375 mg/m2 at day 1 of each cycle of CHOP). Those with a complete or partial remission after 6 cycles of therapy underwent a second randomization to no further treatment (observation) or maintenance treatment with R (375 mg/m2 once every 3 months) until relapse or for a maximum period of two years. Results. 465 patients were randomized to induction with either CHOP (231) or R-CHOP (234). As reported, CHOP and R-CHOP induction yielded similar partial response rates (57% vs.56%), but significantly different CR rates (16% and 29%; p=0.0001). 334 patients were randomized to either R maintenance treatment (167) or observation (167). R maintenance resulted in a highly significant improvement of PFS: median 3.7 years versus 1.3 years in the observation arm (p<0.0001; hazard ratio 0.55). The advantage of R maintenance was observed both after CHOP induction (p< 0001: HR 0.37) and R-CHOP induction (p= 0.003; HR 0.69). The 5 years OS was 74% in the R maintenance arm and 64 % in the observation arm (p=0.07). That the highly improved PFS after R maintenance did not translate into a significant OS advantage might partially be explained by the fact that 41% of progressing patients received R as salvage therapy. This varied according to treatment arm: from 59% after CHOP followed by observation to 26% after R-CHOP followed by R maintenance. R maintenance was associated with a significant increase in grade 3/4 infections: 9.7% vs.2.4% (p= 0.01). 7 of the 167 patients had to discontinue R maintenance because of toxicity, mostly recurrent infection. Conclusion. With long term follow-up we confirm the superior PFS with R maintenance. The improvement of OS did not reach statistical significance, possibly due to the abundant use of R in post-protocol salvage treatment.

Purpose In 2006, we published the results of the European Organisation for Research and Treatment of Cancer phase III trial EORTC 20981 on the role of rituximab in remission induction and maintenance treatment of relapsed/resistant follicular lymphoma (FL). At that time, the median follow-up for the maintenance phase was 33 months. Now, we report the long-term outcome of maintenance treatment, with a median follow-up of 6 years. Patients and Methods Overall, 465 patients were randomly assigned to induction with either six cycles of cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) or rituximab plus CHOP (R-CHOP). Those in complete remission or partial remission after induction (n = 334) were randomly assigned to maintenance treatment with rituximab (375 mg/m2 intravenously once every 3 months) or observation. Results Rituximab maintenance significantly improved progression-free survival (PFS) compared with observation (median, 3.7 years v 1.3 years; P < .001; hazard ratio [HR], 0.55), both after CHOP induction (P < .001; HR, 0.37) and R-CHOP (P = .003; HR, 0.69). The 5-year overall survival (OS) was 74% in the rituximab maintenance arm, and it was 64% in the observation arm (P = .07). After progression, a rituximab-containing salvage therapy was given to 59% of patients treated with CHOP followed by observation, compared with 26% after R-CHOP followed by rituximab maintenance. Rituximab maintenance was associated with a significant increase in grades 3 to 4 infections: 9.7% v 2.4% (P = .01). Conclusion With long-term follow-up, we confirm the superior PFS with rituximab maintenance in relapsed/resistant FL. The improvement of OS did not reach statistical significance, possibly because of the unbalanced use of rituximab in post-protocol salvage treatment.

Anterosuperior temporomandibular joint dislocation is rare. Manual reduction of such dislocation is difficult especially when treatment is delayed. Therefore, it has an increased likelihood of needing surgical intervention to achieve reduction. The authors report a case of an anterosuperior temporomandibular dislocation in a 19-year-old male following a motor vehicle accident. Difficulties were encountered in reducing the dislocation necessitating surgically assisted reduction. The long-term outcome following management by condylotomy is reported. This present report also reviews the literature regarding the classification and management of this uncommon dislocation.

Abstract Background and Aims Contrast induced acute kidney injury (CI-AKI) is potentially preventable and reversable cause of acute kidney injury (AKI). Multiple factors are associated with the development of CI-AKI, some are modifiable such as drugs, type and amount of contrast, others are not like preexisting chronic kidney disease (CKD), heart failure. Though it’s usually a reversable condition, there is increasing evidence of adverse long-term outcome (increasing morbidity and mortality). The aim of this study to evaluate the long-term outcome of CI-AKI on mortality, the rate of re-catheterization and the development of CKD. Method In a prospective observational study design, we evaluated all patients admitted for cardiac catheterization between June 2015 and January 2016. A total of 326 patients signed the consent to participate in the study. Patients had blood withdrawn 48 hours after the procedure for their creatinine level. CI-AKI was defined as an increase in serum creatinine by &gt;25% or 44 mmol/l from the baseline level (48-72) hours after contrast administration, without any other obvious cause. We used only low osmolality contrast media (CM) (Lopamidol, Bayer, Germany). Of the 326 patients included, 202 patients had their second sample taken, thus, were eligible to continue in the study. Patients were followed for at least 3 years. Results The incidence of CI-AKI was 14.8% (30 patients), for baseline characteristics see table 1. At the end of follow up; a total of 7 patients died; 6 in the non CI-AKI group vs. 1 in the CI-AKI group (p= ), though the difference between the mean eGFR was not statistically significant by the end of the follow up (85.4ml/min for the CI-AKI vs. 79.2ml/min for the other group (P=0.31)), but the decline in eGFR for the CI-AKI was significant ( a drop from 105.4 ml/min to 85.4ml/min vs. 85.2ml/min to 79.2ml/min, P=0.004). The rate of re-catheterization was not statistically significant between the two groups (61 for the non CI-AKI vs. 12 for the other group; P=0.63). Conclusion CI-AKI carries a higher negative long-term effect on eGFR, while did not affect the mortality in our cohort.

Background: We investigated the long-term clinical results of percutaneous transluminal angioplasty (PTA) in patients with peripheral arterial occlusive disease (PAOD) and the influence of different parameters on the primary success rate, the rate of complications and the long-term outcome. Patients and methods: We reviewed clinical and hemodynamic follow-up data of 166 consecutive patients treated with PTA in 1987 in our department. Results: PTA improved the clinical situation in 79.4% of patients with iliac lesions and in 88.3% of patients with femoro-popliteal lesions. The clinical stage and ankle brachial index (ABI) post-interventional could be improved significantly (each P < 0,001), the same results were observed at the end of follow-up (each P < 0,001). Major complications occurred in 11 patients (6.6%). The rate of primary clinical long-term success for suprainguinal lesions was 55% and 38% after 5 and 10 years (femoro-popliteal 44% and 33%), respectively, the corresponding data for secondary clinical long-term success were 63% and 56% (60% and 55%). Older age (P = 0,017) and lower ABI pre-interventional (P = 0,019) significantly deteriorated primary clinical long-term success for suprainguinal lesions, while no factor could be identified influencing the outcome of femoro-popliteal lesions significantly. Conclusion: Besides an acceptable success rate with a low rate of severe complications, our results demonstrate favourable long-term clinical results of PTA in patients with PAOD.

There are few long-term follow-up studies of parasuicides incorporating face-to-face interviews. To date no study has evaluated the prevalence of psychiatric morbidity at long-term follow-up of parasuicides using diagnostic rating scales, nor has any study examined parental bonding issues in this population. We attempted a prospective follow-up of 85 parasuicide cases an average of 8½ years later. Psychiatric morbidity, social functioning, and recollections of the parenting style of their parents were assessed using the Clinical Interview Schedule, the Social Maladjustment Scale, and the Parental Bonding Instrument, respectively. Thirty-nine persons in total were interviewed, 19 of whom were well and 20 of whom had psychiatric morbidity. Five had died during the follow-up period, 3 by suicide. Migration, refusals, and untraceability were common. Parasuicide was associated with parental overprotection during childhood. Long-term outcome is poor, especially among those who engaged in repeated parasuicides.
