Background In childhood BCP-ALL, the presence of t(12;21)/ETV6 -RUNX1 defines one of the most prevalent oncogenic subgroup and is usually associated with a favorable outcome. Nevertheless, an excellent prognosis has not been reported by all collaborative groups, suggesting that the outcome of ETV6 -RUNX1 patients (pts) could be influenced by the treatment. To address this issue, the long-term outcome of ETV6 -RUNX1 pts was investigated into the EORTC 58881 and 58951 studies, with particular attention to the effect of the randomized treatments. Methods The 58881 study (1989-1998) used a BFM backbone without cranial irradiation, and aimed to compare E-Coli (Medac®) Asparaginase (A'ase) with Erwinia A'ase and to assess the value of 6-Mercaptopurine (6-MP) i.v. (1 g/m²/month) when added to classic maintenance. The subsequent 58951 study (1999-2008) used the best arm of the trial 58881, i.e. E-Coli A'ase and classic maintenance. The aims of this study were to compare dexamethasone (Dexa) (6 mg/m²/day) with prednisone (Pred) (60 mg/m²/day) during induction and maintenance; to evaluate increased number of A'ase administrations (24 vs 12) for non-very high risk pts; and to assess the value of vincristine/corticosteroid pulses during maintenance for average risk pts. Detection of ETV6 -RUNX1 by FISH and/or RT-PCR was centralized. Pts less than 1 year (yr) or with t(9;22)/BCR-ABL were excluded from the analysis. Results An ETV6 -RUNX1 was evidenced in 104/363 (28%) and 380/1493 (27%) newly diagnosed BCP-ALL pts enrolled in the 58881 and 58951 trial respectively. A majority of ETV6-RUNX1 pts were below the age of 10 yrs (93.3% in 58881 and 91.3% in 58951). The median follow-up was 11.8 yrs for the 58881 and 6.7 yrs for the 58951. In both studies, the 10-yr event-free-survival (EFS) rate was significantly higher for ETV6 -RUNX1 pts than for all BCP-ALL pts (82.5% vs 74.9% in 58881 and 90.8% vs 82.7% in 58951), and was similar to the 10-yr EFS of hyperdiploid pts. Noteworthy, very few EFS events were observed during treatment period or after 6 yrs from diagnosis. The main prognostic factors of the ETV6-RUNX1 subgroup in both studies were the white blood cell count (WBC) and the response to prephase. As shown in the table below, the analysis of the relationship between treatment modalities and outcome revealed that the in vivo drug sensitivity of ETV6-RUNX1 ALL was distinct from that of other BCP-ALL. In this subgroup, the benefit of a more potent A'ase (58881) or of intensified A'ase administrations (58951) was less pronounced as compared to other pts, and 6-MP i.v. during maintenance was particularly deleterious. Moreover, the overall benefit of vincristine/corticosteroid pulses was not observed in ETV6-RUNX1 average risk group pts, who already had an outstanding outcome. By contrast, the use of Dexa in place of Pred significantly improved the 10-yr EFS of ETV6-RUNX1 pts (95.0% vs 87.2%, hazard ratio (HR)=0.44, 95% CI 0.20-0.96) whereas no difference was observed in the remaining population (HR=1.01, 95% CI 0.77-1.33) (test for interaction: p=0.04).

Our data also show that this excellent outcome can be jeopardized by slight changes in therapy, such as the addition of 6-MP i.v. to classic maintenance. Together, these results stress the importance of analyzing homogeneous oncogenetic subgroups when comparing different therapeutic schemes, to unmask specific drug effects that could be hidden when analyzing the whole group of patients.

Abstract Background Cranial radiotherapy (CRT) is associated with early and late side effects. Intrathecal (IT) and systemic chemotherapy could successfully replace CRT in most protocols for standard risk ALL. However, in medium and high risk ALL patients (pts) its omission is still debatable. Aim We investigated the long-term outcome, the occurrence of second malignant neoplasms (SMN) and the incidence of late toxicities in pts randomized for receiving or not CRT in the EORTC 58832 study. Methods From 1983 to 1989, ALL children under 18 years (yrs) were included in EORTC Children Leukemia Group BFM-oriented studies, either 58831, for standard risk pts (Riehm-Langerman Risk Factor (RF) < 1.2), or 58832, for medium risk (RF 1.2-1.69) and high risk pts (RF ≥1.7). Pts with central nervous system (CNS) involvement at diagnosis were ineligible. The present report focusses on pts included in the 58832 trial (randomized for receiving or not prophylactic CRT). Prophylactic CNS therapy consisted of 4 high-dose methotrexate (HD-MTX) injections (2500 mg/m2) during consolidation and 7 IT MTX injections scheduled during the treatment period. Pts still in complete remission (CR) after the end of late intensification were randomized for receiving prophylactic CRT (standard arm) or not (experimental arm) before the start of continuation therapy. Dose of CRT was age dependent: 24 Gy (> 2 yrs), 20 Gy (1-2 yrs) and 16 Gy (< 1 yr). Endpoints were: disease-free survival (DFS) (event: relapse, death in CR), incidence of SMN, event-free survival (EFS) (event: relapse, death in CR, SMN), incidence of late toxicities, and overall survival (OS) from randomization. Results 788 pts were included in the 58831/58832 study. Among them, 189 were randomized in the 58832 study to receive CRT (n=93) or No CRT (n=96). A total of 6 pts did not meet eligibility criteria, 2 had an early relapse, 3 had an early protocol violation and 2 refused allocated treatment. Finally, 176 randomized pts were included in the analyses: 84 in the CRT group and 92 in the No CRT group. The median follow-up was 20 yrs (range 4-32 yrs). Omission of CRT did not increase the 25-yr incidence of isolated CNS relapse, any CNS relapse or non-CNS relapse (4.8 vs 6.5; 11.9 vs 8.7 and 16.7 vs 21.8 in the CRT vs No CRT arms, respectively). No relapses occurred after 10 yrs. The 25-yr DFS rates were similar in both arms: 70.2% with CRT and 67.4% without CRT; No CRT vs CRT hazard ratio (HR)=1.08, 95% CI (0.63, 1.83). CRT was associated with an increase of the 25-yr SMN incidence: 13.2% with CRT and 3.9% without CRT. In the CRT arm, 9 pts (10.7%) developed SMN: 2 acute myeloid leukemias (AML), 1 non-Hodgkin lymphoma, 1 thyroid carcinoma, 4 meningiomas and 1 malignant histiocytosis. One SMN (meningioma) occurred after a CNS combined relapse. Three pts developed second SMN (meningiomas): 1 after an AML and 2 after a first meningioma. In the No CRT arm, 3 pts (3.3%) had SMN: 1 pleomorphic xanthoastrocytoma, 1 melanoma and 1 adenocarcinoma of the ileum. One SMN occurred after a bone marrow (BM) relapse. The 25-yr EFS rates were similar in both arms: 60.3% with CRT and 63.2% without CRT, HR=0.90, 95% CI (0.55, 1.46). CRT was also associated with an increase of late CNS and endocrine toxicities. Five pts (19.2% of the pts with available data) developed leukoencephalopathy in the CRT arm, versus 2 pts (8.7%) in the No CRT arm. Noteworthy, 1 of those 2 pts received CRT for a BM relapse, while the other received total body irradiation for a CNS relapse. Stroke was observed in 2 pts (7.7%) who received CRT. In contrast, there was no clear increase of the incidence of cognitive disturbance after CRT: 33.3% in the CRT arm vs 25.0% in the No CRT arm. Regarding endocrine toxicities, GH deficiency, hypothyroidism and precocious puberty were more frequent in the CRT arm: 53.1% vs 29.6%, 27.8% vs 0% and 29.4% vs 0%, respectively. Finally, the 25-yr OS rates were similar in both arms: 78.5% with CRT and 78.1% without CRT, HR=1.00, 95% CI (0.53, 1.88). Conclusion In medium and high risk pts without CNS involvement at diagnosis and treated with HD-MTX in the EORTC trial 58832 (1983-1989), omission of CRT did not increase the risk of CNS or non-CNS relapse. On long-term evaluation, CRT was associated with a higher incidence of SMN, late CNS and endocrine toxicities. These long-term results indicate that prophylactic CRT can be safely omitted in childhood medium and high risk ALL pts receiving IT and systemic chemotherapy (including HD-MTX) as CNS prophylaxis.

There has been significant improvement in device designs, operative techniques, and early clinical outcomes in <5 years. Presently, there are two catheter-based bioprostheses (balloon expandable or self-expandable), which have been widely used in humans and are undergoing clinical investigations. Three approaches, including transvenous, transarterial, and transapical have been used for delivery of the catheter-based bioprostheses, and transarterial and transapical approaches have been adopted by cardiologists and cardiac surgeons worldwide. The most recent clinical results have been very encouraging and promising. With experience, 30-day operative mortality with either balloon-expandable or self-expandable bioprosthesis was reduced significantly to approximately 10% in high-risk patients. In vivo long-term durability of catheter-based bioprostheses remains unknown, and presently transcatheter procedure is limited to the cohort of high-risk patients. Expanding this new technology to low-risk patients should be done with extreme caution because conventional aortic valve replacement still provides the best long-term outcome with minimal operative mortality and morbidity in low-risk patients. Ongoing clinical trials will address many unanswered questions, such as patient selection, long-term in vivo durability, preoperative assessment, and the role of the procedures in management of valvular diseases.

Background:Aortitis is a group of disorders characterized by the inflammation of the aorta. The most common causes of aortitis are the large-vessel vasculitis i.e. giant cell arteritis (GCA) and Takayasu arteritis (TA). However, aortitis may be isolated. Because of the wide variation in the course of aortitis, predicting outcome is challenging. The optimal management strategy of isolated aortitis (IA) is still unclear as IA is poorly defined, with data consisting of small retrospective and case control studies.Objectives:To assess the long-term outcome and prognosis factors for vascular complications in patients with isolated aortitis.Methods:Retrospective multicenter study of 353 patients with non-infectious aortitis including 136 giant cell arteritis (GCA), 96 Takayasu arteritis (TA) and 73 isolated aortitis (IA). Factors associated with event-free survival, vascular event-free survival and revascularization-free survival were assessed. Risk factors for vascular complications were identified in multivariate analysis.Results:After a median follow up of 52 months, vascular complications were observed in 32.3 %, revascularization in 30 % and death in 7.6%. The 5-year cumulative incidence of vascular complications was 58% (41; 71), 20% (13; 29), and 19 % (11; 28) in IA, GCA and TA, respectively. In multivariate analysis, IA [HR, 1.85 (1.19 to 2.88), p=0.017] and male gender [1.77 (1.26 to 2.49), p<0.0001] were independently associated with vascular events. The 5-year surgery-free survival was 45% (31; 65), 71% (62; 81) and 76% (68; 86) in IA, TA and GCA, respectively.Conclusion:IA has a worse vascular prognosis than GCA and TA. Sixty percent of IA patients will experience a vascular complication within 5 years from diagnosis.Disclosure of Interests:None declared
