    Abstract: In nonurban areas with limited access to thrombectomy-capable centers, optimal prehospital transport strategies in patients with suspected large-vessel occlusion stroke are unknown. Objective To determine whether, in nonurban areas, direct transport to a thrombectomy-capable center is beneficial compared with transport to the closest local stroke center. Design, Setting, and Participants Multicenter, population-based, cluster-randomized trial including 1401 patients with suspected acute large-vessel occlusion stroke attended by emergency medical services in areas where the closest local stroke center was not capable of performing thrombectomy in Catalonia, Spain, between March 2017 and June 2020. The date of final follow-up was September 2020. Interventions Transportation to a thrombectomy-capable center (n = 688) or the closest local stroke center (n = 713). Main Outcomes and Measures The primary outcome was disability at 90 days based on the modified Rankin Scale (mRS; scores range from 0 [no symptoms] to 6 [death] ) in the target population of patients with ischemic stroke. There were 11 secondary outcomes, including rate of intravenous tissue plasminogen activator administration and thrombectomy in the target population and 90-day mortality in the safety population of all randomized patients. Results Enrollment was halted for futility following a second interim analysis. The 1401 enrolled patients were included in the safety analysis, of whom 1369 (98%) consented to participate and were included in the as-randomized analysis (56% men; median age, 75 [IQR, 65-83] years; median National Institutes of Health Stroke Scale score, 17 [IQR, 11-21] ); 949 (69%) comprised the target ischemic stroke population included in the primary analysis. For the primary outcome in the target population, median mRS score was 3 (IQR, 2-5) vs 3 (IQR, 2-5) (adjusted common odds ratio [OR], 1.03; 95% CI, 0.82-1.29). Of 11 reported secondary outcomes, 8 showed no significant difference. Compared with patients first transported to local stroke centers, patients directly transported to thrombectomy-capable centers had significantly lower odds of receiving intravenous tissue plasminogen activator (in the target population, 229/482 [47.5%] vs 282/467 [60.4%]; OR, 0.59; 95% CI, 0.45-0.76) and significantly higher odds of receiving thrombectomy (in the target population, 235/482 [48.8%] vs 184/467 [39.4%]; OR, 1.46; 95% CI, 1.13-1.89). Mortality at 90 days in the safety population was not significantly different between groups (188/688 [27.3%] vs 194/713 [27.2%]; adjusted hazard ratio, 0.97; 95% CI, 0.79-1.18). Conclusions and Relevance In nonurban areas in Catalonia, Spain, there was no significant difference in 90-day neurological outcomes between transportation to a local stroke center vs a thrombectomy-capable referral center in patients with suspected large-vessel occlusion stroke. These findings require replication in other settings. Trial Registration ClinicalTrials.gov Identifier: NCT02795962

    In: Stroke, Ovid Technologies (Wolters Kluwer Health), Vol. 53, No. 12 ( 2022-12), p. 3728-3740
    Abstract: We aim to compare the outcome of patients from urban areas, where the referral center is able to perform thrombectomy, with patients from nonurban areas enrolled in the RACECAT trial (Direct Transfer to an Endovascular Center Compared to Transfer to the Closest Stroke Center in Acute Stroke Patients With Suspected Large Vessel Occlusion). Methods: Patients with suspected large vessel occlusion stroke, as evaluated by a Rapid Arterial Occlusion Evaluation score of ≥5, from urban catchment areas of thrombectomy-capable centers during RACECAT trial enrollment period were included in the Stroke Code Registry of Catalonia. Primary outcome was disability at 90 days, as assessed by the shift analysis on the modified Rankin Scale score, in patients with an ischemic stroke. Secondary outcomes included mortality at 90 days, rate of thrombolysis and thrombectomy, time from onset to thrombolysis, and thrombectomy initiation. Propensity score matching was used to assemble a cohort of patients with similar characteristics. Results: The analysis included 1369 patients from nonurban areas and 2502 patients from urban areas. We matched 920 patients with an ischemic stroke from urban areas and nonurban areas based on their propensity scores. Patients with ischemic stroke from nonurban areas had higher degrees of disability at 90 days (median [interquartle range] modified Rankin Scale score, 3 [2–5] versus 3 [1–5], common odds ratio, 1.25 [95% CI, 1.06–1.48] ); the observed average effect was only significant in patients with large vessel stroke (common odds ratio, 1.36 [95% CI, 1.08–1.65]). Mortality rate was similar between groups(odds ratio, 1.02 [95% CI, 0.81–1.28] ). Patients from nonurban areas had higher odds of receiving thrombolysis (odds ratio, 1.36 [95% CI, 1.16–1.67]), lower odds of receiving thrombectomy(odds ratio, 0.61 [95% CI, 0.51–0.75] ), and longer time from stroke onset to thrombolysis (mean difference 38 minutes [95% CI, 25–52]) and thrombectomy(mean difference 66 minutes [95% CI, 37–95] ). Conclusions: In Catalonia, Spain, patients with large vessel occlusion stroke triaged in nonurban areas had worse neurological outcomes than patients from urban areas, where the referral center was able to perform thrombectomy. Interventions aimed at improving organizational practices and the development of thrombectomy capabilities in centers located in remote areas should be pursued.

    In: Stroke, Ovid Technologies (Wolters Kluwer Health), Vol. 54, No. 3 ( 2023-03), p. 770-780
    Abstract: We aim to assess whether time of day modified the treatment effect in the RACECAT trial (Direct Transfer to an Endovascular Center Compared to Transfer to the Closest Stroke Center in Acute Stroke Patients With Suspected Large Vessel Occlusion Trial), a cluster-randomized trial that did not demonstrate the benefit of direct transportation to a thrombectomy-capable center versus nearest local stroke center for patients with a suspected large vessel stroke triaged in nonurban Catalonia between March 2017 and June 2020. Methods: We performed a post hoc analysis of RACECAT to evaluate if the association between initial transport routing and functional outcome differed according to trial enrollment time: daytime (8:00 am –8:59 pm ) and nighttime (9:00 pm –7:59 am ). Primary outcome was disability at 90 days, as assessed by the shift analysis on the modified Rankin Scale score, in patients with ischemic stroke. Subgroup analyses according to stroke subtype were evaluated. Results: We included 949 patients with an ischemic stroke, of whom 258 patients(27%) were enrolled during nighttime. Among patients enrolled during nighttime, direct transport to a thrombectomy-capable center was associated with lower degrees of disability at 90 days (adjusted common odds ratio [acOR] , 1.620 [95% CI, 1.020–2.551]); no significant difference between trial groups was present during daytime (acOR, 0.890 [95% CI, 0.680–1.163] ; P interaction =0.014). Influence of nighttime on the treatment effect was only evident in patients with large vessel occlusion(daytime, acOR 0.766 [95% CI, 0.548–1.072]; nighttime, acOR, 1.785 [95% CI, 1.024–3.112] ; P interaction 〈 0.01); no heterogeneity was observed for other stroke subtypes ( P interaction 〉 0.1 for all comparisons). We observed longer delays in alteplase administration, interhospital transfers, and mechanical thrombectomy initiation during nighttime in patients allocated to local stroke centers. Conclusions: Among patients evaluated during nighttime for a suspected acute severe stroke in non-urban areas of Catalonia, direct transport to a thrombectomy-capable center was associated with lower degrees of disability at 90 days. This association was only evident in patients with confirmed large vessel occlusion on vascular imaging. Time delays in alteplase administration and interhospital transfers might mediate the observed differences in clinical outcome.

    Genomic Characterization of Paired Diagnosis and Relapse Samples from Adult Patients with B-Cell Precursor Acute Lymphoblastic Leukemia
    American Society of Hematology ; 2016

    In: Blood, American Society of Hematology, Vol. 128, No. 22 ( 2016-12-02), p. 5281-5281
    Abstract: Background & Objective: Acute Lymphoblastic Leukemia (ALL) is an aggressive neoplasia characterized by a high genetic heterogeneity both at diagnosis and at relapse. Due to the high incidence of relapse in adults and the dismal prognosis beyond recurrence, diagnosis and relapse samples of adult ALL patients were carefully analyzed in order to identify genetic alterations related with drug resistance and disease progression. Patients & Methods: Paired diagnosis-relapse bone marrow samples from 5 adult B-cell precursor ALL (B-ALL) patients were analyzed (Ph+ ALL [n=2], normal karyotype [n=1] , t(1;19)(q23;p13) [n=1] and t(8;13)(p21-22;q12) [n=1] ). Copy Number Alterations (CNA) were studied with Multiplex Ligation-dependent Probe Amplification (MLPA, kits P-335 and P-202 from MRC-Holland, Amsterdam, Netherlands) and Affymetrix CytoScan HD arrays (Affymetrix, Santa Clara, USA). In the array analyses, only the CNA that encompassed at least 25 markers were considered significant. Results: Regarding karyotype, 2 patients (1 Ph+ and 1 t(1;19) at diagnosis) showed the same chromosomal translocations within a complex karyotype at relapse. On the contrary, the other Ph+ patient showed a normal karyotype at relapse, while 2 patients did not experience any karyotypic change. Regarding immunophenotype, 3/5 patients showed changes on antigen expression from diagnosis to relapse such as expression of markers of immaturity (CD34, TdT positivity and CD38 negativity), loss of lymphoid markers (CD20 and CD22) and/or acquisition of myeloid markers (CD33 and CD66c). Concerning CNA, all relapse samples were genetically related to the diagnosis clone (common clonal origin). All relapsed populations lost CNA detected at diagnosis and/or acquired new CNA but retained some of the CNA showed at diagnosis revealing clonal evolution from ancestral clones. CNA in B-ALL key genes involved in lymphoid development (IKZF1, PAX5, EBF1,VPREB1 and BLNK), proliferation (CDKN2A/B, RB1, CRLF2, C-MYC and ERG), apoptosis (BTG1, TP53 and ATM), hematopoiesis transcription factors (ETV6 and MLL) and histone modifications (KDM6A) were detected, among others. Losses in 9p were the most recurrent event both at diagnosis and at relapse. CDKN2A/B deletions were observed in all relapse samples (3/5 in homozygosis) while PAX5 deletions were present in 4/5 relapsed cases. Interestingly, all relapse samples showed CNA favoring the activation and/or the transcription of proteins involved in the Akt/C-MYC signaling pathway. Another common feature (4/5 patients) were CNA affecting genes involved in drug transport such as several ABC transporter genes and genes related to drug resistance such as PRKDC and RUNX1T1 (in 3/4 of the cases, the CNA appeared exclusively at relapse or were already present at diagnosis and increased their frequency at relapse). CNA in genes that may confer stem cell characteristics (EGR1 and USP16) were another recurrent event at relapse (3/5 samples, 2 of them were not present at diagnosis). CNA affecting the X/Y PAR1 region (CRLF2, CSF2RA and IL3RA) or VPREB1 at 22q11.22 were detected in 3/5 relapse samples, respectively. An important apoptosis cluster at 11q21q24.2 (BIRC2/3, CASP1/4/5/12, hsa-miR-34b/c, ATM and BTG4) was lost in 2/5 relapse samples (one of them was not detected at diagnosis and the other increased its frequency at relapse). Finally, ETV6 deletion (12p13.2) and duplication of Xq26.2q28 (containing ABCD1, BCAP31 and genes coding for several cancer/testis antigens) were observed in 2 relapse samples. Conclusions: SNP arrays analysis of paired B-cell precursor ALL samples at diagnosis and at relapse allows the identification of genetic alterations potentially related with ALL progression. The systematic analysis of relapse samples could contribute to the identification of specific genetic targets with potential therapeutic impact for each patient (personalized medicine).

    Abstract: The prognostic significance of low‐hypodiploidy has not been extensively evaluated in minimal residual disease (MRD)‐oriented protocols for adult acute lymphoblastic leukaemia (ALL). We analysed the outcome of hypodiploid adult ALL patients treated within Programa Español de Tratamientos en Hematología (PETHEMA) protocols. The 5‐year cumulative incidence of relapse (CIR) of low‐hypodiploid B‐cell precursor (BCP)‐ALL was significantly higher than that of high‐hypodiploids (52% vs. 12%, P  = 0.013). Low‐hypodiploid BCP‐ALL patients aged ≤35 years showed superior survival (71% vs. 21%, P  = 0.026) and lower 5‐year CIR (17% vs. 66%, P  = 0.090) than low‐hypodiploids aged 〉 35 years. Older adults and elderly low‐hypodiploid BCP‐ALL patients show dismal prognosis although achieving an end‐induction good MRD response.

    Abstract: Introduction: Recent studies have shown that young to middle-aged adults who receive a pediatric-inspired chemotherapy regimen for treatment of Ph-neg ALL do not appear to require an alloHSCT if they achieve good response on MRD testing after induction and/or consolidation therapy. Patients (pts) who are not good MRD responders achieve better outcomes with alloHSCT than their counterparts who do not receive alloHSCT. However, it is not clear if this approach can specifically apply to adult ALL pts with HR features at baseline. The aim of the prospective ALL-HR-11 trial (NCT01540812) from the Spanish PETHEMA Group was to evaluate response of HR Ph-neg adult ALL patients to a different post-induction therapy (chemotherapy or alloHSCT) according to MRD levels (centrally assessed by 8-color flow cytometry [FCM] ) at the end of induction (week 5) and consolidation therapy (week 17).. Patients and methods: HR ALL included one or more of the following parameters at baseline: age 30-60y, WBC count & gt;30x109/L for B-cell precursor ALL or & gt;100x109/L for thymic T-ALL, pro-B, early or mature T-ALL, 11q23 or KMT2A rearrangements or complex karyotype. Induction therapy included vincristine, prednisone, daunorubicin and asparaginase (E coli native or PEG according to center availability) for 4 weeks (Induction-1). FLAG-Ida was administered as intensified induction (Induction-2) in pts not achieving CR or in those in CR with MRD≥0.1% at the end of induction. For pts in CR and MRD & lt;0.1% early consolidation therapy included 3 cycles with rotating cytotoxic drugs with high-dose methotrexate, high-dose ARA-C and high-dose asparaginase (E coli native or PEG). These pts continued with delayed consolidation (identical to that of early consolidation) followed by maintenance therapy up to 2y in CR if MRD levels after consolidation were & lt;0.01%; otherwise they were assigned to alloHSCT. Pts in CR after Induction-2 received one consolidation cycle and were assigned to alloHSCT. Main outcome measures were: complete response (CR), overall survival (OS) and cumulative incidence of relapse (CIR), assessed by competing risk analysis. Results: On April 2019, 307 HR ALL pts were evaluable. Median (range) age was 40 (15-60) y, 192 were males, 211 precursor B-ALL and 96 T-ALL, with a median WBC count of 12.9 (0.2-564) x109/L. Results of Induction-1 (n=304, 3 on induction): therapy-related death: 12(4%), resistance: 39(13%), CR: 253(83%). MRD & lt;0.1% at the end of induction was observed in 77% of CR patients. Induction-2 was administered to 88 patients (due to no CR: 37, or to CR and MRD≥0.1%: 51). Overall response rate: 277 (91%). The 5y CIR and OS probabilities for the whole series were of 44%±8% and 48%±7% (median follow-up: 2.06y [range: 0-7.55y]). By intention-to treat after Induction-1, 94 pts were assigned to alloHSCT and 190 to delayed consolidation and maintenance. The 5y CIR and OS probabilities were of 37%±13% and 38%±11%, respectively, for pts assigned to alloHSCT, and of 48%±10% and 55%±10%, respectively, for those assigned to chemotherapy (P & lt;0.001 for OS [Figure 1], and P=0.243 for CIR). Patients with MRD & lt;0.1% at the end of induction and MRD & lt;0.01% at the end of consolidation (n=137) showed a 5y CIR and OS of 42%±11% and 66%±11%, respectively (P & lt;0.001 for both, Figure 2). Patients with MRD levels & lt;0.01% on day14 of induction-1, end-induction-1 and end-consolidation (n=17) showed 5y CIR and OS probabilities of 17%±19% and 90%±19%, respectively. Conclusions: This trial, in which post-induction therapy was only based on MRD results assessed by FCM, suggests that avoiding alloHSCT does not hamper the outcome of HR Ph-neg adult ALL pts with adequate MRD response after induction and after consolidation. Better post-remission alternative therapies are specially needed for patients with poor MRD clearance. Supported by grants PI14/01971 FIS, Instituto Carlos III, and SGR225 (GRE), Spain.

    Abstract: Background and objective. The combination of HyperCVAD and ponatinib resulted in a high molecular response rate and survival in adults with Ph+ ALL, suggesting improved outcome compared with combinations of chemotherapy with first- or second-generation tyrosine kinase inhibitors (TKI) (Jabbour E, et al, Lancet Haematol. 2018;5:e618-e627). The Spanish PETHEMA group conducted the phase 2 PONALFIL trial, which incorporates ponatinib to the same chemotherapy as that of the ALL Ph08 trial that used imatinib as TKI (Ribera JM et al. Cancer 2019;125:2810-17). Final results of this trial are reported. Patients and method. PONALFIL trial (NCT02776605) combined ponatinib (30 mg/d) and induction chemotherapy (vincristine, daunorubicin, prednisone) followed by consolidation (high-dose methotrexate, high-dose ARA-C, mercaptopurine, etoposide) and allogeneic hematopoietic stem cell transplantation (alloHSCT). Ponatinib was scheduled after alloHSCT only for patients (pts) with persistence/reappearance of MRD. Response to therapy (complete morphological [CR], molecular [complete -CMR- or major -MMR-] after induction and before alloHSCT) (assessed by centralized BCR-ABL1/ABL1 ratio), disease-free survival (DFS), overall survival [OS]) and toxicity were analyzed. The following genetic studies were performed: 1. Additional gene abnormalities (Copy Number Alteration [CNA] analysis by SNP array Affymetrix 750K), 2. ABL1 mutation status at diagnosis (Sanger sequencing), 3. T315I mutation at diagnosis (allele-specific PCR). A propensity score comparison with the results of the ALL Ph08 trial was performed. Results. Median age was 49 (19-59) years (y), and 13/30 pts were female. One pt showed CNS involvement at diagnosis. ECOG score was & lt;2 in 90% of pts. Median WBC count was 6.4 x10 9/L (0.6-359.3), Hb 90 g/L (63-145), platelets 38 x10 9/L (11-206). Immunologic phenotype was common in 26 cases, with p190 isoform in 20 pts (67%), p210 in 9 (30%) and p230 in 1 (3%). CR was attained in 30/30 pts, CMR in 14/30 (47%), MMR in 5/30 (17%) and no molecular response in 11/30 (37%). Two pts withdrew the trial during induction (thrombosis of central retina artery and severe intestinal infection, one case each). Consolidation was given to 28 pts, 2 pts withdrew the trial (physician's decision and lack of molecular response, one case each) and 26 pts received alloHSCT (20 in CMR, 6 in MMR). No relapses before HSCT were detected. One pt died by severe GVHD and two withdrew the trial (grade IV hepatic toxicity:1, protocol deviation after molecular relapse:1). One pt relapsed in BM after HSCT. Ponatinib was given after HSCT in 4/26 pts and dasatinib in 1/26 due to MRD reappearance, and 1/26 received dasatinib in CMR because of refusal to receive CNS prophylaxis, whereas 20/26 pts did not receive any TKI therapy after HSCT. Twenty-nine pts are alive (median follow-up 2.3y, range 1.3-4). 2y DFS and OS probabilities were 97% (91%-100%) and 97% (91%-100%) (Figure 1). Among 7/16 pts without CMR after consolidation and genetic material available, 4 showed IKZF1 deletion (IKZF1 plus in 2), 1 showed CDKN2A/B and PAX5 deletion and 2 did not show any CNA. Among 5/19 pts with molecular relapse, 3 showed IKZF1 deletion (1 being IKZF1 plus), and 2 pts did not show any CNA. No ABL1 mutations or T315I mutation at diagnosis were found. Propensity score with 1:1 matching identified 30 pts in each cohort (variables: age, gender, ECOG, WBC, CNS involvement, cytogenetic risk and BCR/ABL isoform). 2y DFS rates for PONALFIL and ALL Ph08 trials were 97% and 62%, (p=0.005), and 2y OS rates were 97% and 66% (p=0.001) (Figure 2). 107 adverse events (AE) were registered in 20 pts (21 severe in 11 pts), prompting to withdrawn of the trial in 3 (thrombosis of central retina artery, severe bowel infection, grade IV hepatic toxicity). The most frequent AE were hematologic (28%), gastrointestinal (14%), hepatic (11%), infections (7%), and cutaneous (5%). Cardiovascular events occurred in 2 patients (angor pectoris and thrombosis of central artery of the retina). Conclusions. The results of the PONALFIL trial show a high antileukemic efficacy with acceptable toxicity profile and compare favorably with the same chemotherapy schedule and imatinib.

    Abstract: Background: ETP-ALL was included as a provisional identity in the 2016 WHO classification of ALL. This subtype was first identified by Coustan-Smith et al. in 2009. However, this immunophenotype-based classification does not fully enclose all ETP-ALL cases identified by gene expression profile (GEP). Although early studies in small series of ETP-ALL suggested a very poor outcome for ETP ALL more recent and larger series have showed improvement in outcome treating children with a contemporary protocol based on chemotherapy schedules, or after allogeneic stem cell transplantation (allo-SCT) in adults. Aim: To investigate the clinical and biological features of ETP-ALL cases in the Spanish cohort of adult T-cell ALL (T-ALL) patients and to assess the potential impact of high-risk therapy on their outcome. Method: One hundred eighty-five adults with T-ALL treated according to two consecutive MRD-oriented high-risk adult PETHEMA protocols -ALL-HR-2003 (NCT00853008) and ALL-HR-11 (NCT01540812; still ongoing)- were included in this study. The EGIL criteria were used to define the immunologic subtype of T-ALL after central review of immunophenotype reports, and the criteria proposed by Zuurbier et al. (Zuurbier L. et al. Haematologica 2014; 99:94-102) were used to define ETP-ALL. These later criteria consist of a combination of immunophenotypic markers (absence of CD1a-/CD4-/CD8-, cut-off 〈 10%, and expression of the stem cell marker CD34+and/or at least one myeloid marker such as CD13+or CD33+, cut-off 〉 25%), that resemble those published by Coustan-Smith, with the advantage that include most ETP-ALL cases, as identified by GEP, avoiding the use of partial expression of CD5 marker to immuno-classify these patients. Results: Thirty-four out of 167 evaluable patients (20%) with T-ALL showed an ETP-ALL immunophenotype. Patients with ETP-ALL were older (mean 39 [SD 12] vs. 33 [12] yr; p=0.011), showed more frequently lymph node involvement (79% vs. 56%; p=0.021) and lower WBC counts at diagnosis (mean, 72 [155] vs. 97 [112] x109/L; p=0.004). At genetic level, ETP-ALL patients were associated with the absence of deletions in CDKN2A/B gene cluster (91% vs. 26%; p 〈 0.001) (10/11 cases) and with the absence of bi-allelic deletions in TCRG gene (67% vs. 5%; p=0.001) (6/9 cases). In turn, ETP-ALL patients showed poorer response to induction therapy: 82% of ETP-ALL had poorer early cytologic response ( 〉 10% BM blasts on day+14) vs. 37% of non-ETP (p 〈 0.001), and 23% of ETP-ALL patients did not reach CR vs. 6% non-ETP T-ALL cases (p=0.005). Flow-MRD data at CR (available in 141/167 patients) showed MRD levels ≥0.1% in 65% of ETP-ALL vs. 18% of non-ETP ALL (p 〈 0.001), and MRD level ≥0.01% in 85% vs. 37%, respectively (p 〈 0.001). Forty-six percent of ETP-ALL patients required a second induction treatment compared to 8% of non-ETP-ALL (p 〈 0.001). Consequently, more ETP-ALL patients underwent allo-SCT (70% vs. 21%, p 〈 0.001). The OS of ETP-ALL patients was poorer after censoring or not the follow-up at the time of transplant (Figures 1A and B). Conclusions: ETP-ALL accounts for 20% of adult T-ALL in the PETHEMA cohort and it is associated with a poorer initial response to treatment (lower CR rate, poorer MRD clearance) than the remaining T-ALL patients. Such poorer outcome is not overcome by allo-SCT in our series.
