Abstract: Abstract 4711 Aim To analyze the prognostic impact of cytogenetics and main molecular abnormalities on the achievement of complete remission (CR), in patients with primary (de novo) AML (M3 excluded). Patients and Methods Between december-2003 and july-2009, 605 patients up to 70 years-old were included in the CETLAM AML-03 protocol. Induction therapy consisted in one or two courses of idarubicin, intermediate dose ara-C and etoposide, in addition to G-CSF priming from day 0. Cytogenetics classification was as in the MRC studies: Favorable prognosis (FP), intermediate (IP) and adverse (AP). In the IP group, molecular analysis of NPM1 (NPM1+) mutations, CEBPA mutations and internal tandem duplication of FLT3 gene (ITD/FLT3) was performed. In the AP group, the absence (MK-) or presence of monosomal karyotype (MK+) was studied; MK+ was defined as 2 or more autosomal monosomies, or one monosomy and ≥1 structural alteration. Results Median age of the series was 53 years (range, 16-73). In 538 (89%) patients cytogenetic data were available; of them, 64 (10,5%) had FP, 375 (61,8) IP (included 255 with normal cytogenetics) and 99 (16,3%) AP. In the FP group, 33 (5,4%) had the AML1/ETO fusion and 31 (5,1%) the CBF/MYH11. In the IP group, 121 (31%) of 279 patients studied were NPM1+, 100 (26,7%) of 346 were DIT/FLT3+ and 22 (6%) of 235 analyzed were CEBPA+. In patients with AP, 47 were MK- and 33 MK+. Overall, 447 (73,8%) of 588 patients evaluable at the moment of the analysis achieved a CR. CR rates according cytogenetics were: FP 92,2%, IP 76,5% and AP 69,4%, p=0.01. In AML, with AML1-ETO+ and CBF/MYH11+, CR rates were 91% and 93.5%, respectively; of note no chemorefractory cases were observed. In the IP group, CR rates according to mutational status were: NPM1+/FLT3- 91.2%, CEBPA+/FLT3- 94.4%, no mutations 79.1% and DIT/FLT3+ 69.7% (p=0.003). Again, no refractoriness was observed in patients in IP patients belonging to the two groups with favourable molecular profile (p=0.003). In patients with AP, CR rate was 76.1% if MK- and 65.6% if MK+ (p=0.46). The prognostic impact of the herein described cytogenetic and molecular findings was confirmed in multivariate analyses. Comments Genetic characterization is nowadays mandatory in AML. CR rate is high and refractoriness exceptional in the presence of AML1-ETO or CBF/MYH11 rearrangements, or NPM1 or CEBPA mutations without DIT/FLT3. In contrast, CR probability is lower in AP group patients, mainly in those with MK+. These patients require new strategies within clinical trials.

Abstract: BACKGROUND: The progress in the understanding of pathophysiology of AML has allowed the identification of genetic and immune abnormalities with prognostic impact on outcome and suitable as therapeutic targets. The genetic abnormalities are essential for risk allocation and risk-adapted treatment included the indication of hematopoietic cell transplantation. In the last decade, several studies have shown that persistence of measurable residual disease (MRD) after chemotherapy increases relapse incidence and the probability of leukemia recurrence and survival. Therefore, MRD has been progressively incorporated in prognosis estimation. In the last 25 years the CETLAM cooperative group has promoted 4 consecutive trials for AML patients fit for intensive chemotherapy and eventually HCT. Post-remission treatment was based on genetics of the disease and more recently on MRD. The aim of this study has been to investigate if the survival of patients has improved and, if so, to identify the factors that have influenced on the better outcome. METHODS: We included all patients with primary AML up to the age of 60 years enrolled in 4 consecutive Spanish CETLAM group trials. In brief, induction chemotherapy included idarubicin, cytarabine and etoposide in AML-94, AML-99 and AML-03 protocols and without etoposide in the AML-12. G-CSF priming was allowed in the two more recent trials. Post remission therapy included 1 to 3 consolidations including intermediate or high dose cytarabine. Hematopoietic transplantation indication was based on availability of an HLA-compatible donor, genetic findings and more recently MRD. Follow-up was extended to June 2020. The survival and relapse incidence analyses were censored at 5 years. Informed consent was obtained in all cases and the institutional review boards approved the protocols. RESULTS: Between 1994 and 2019, 1755 primary AML patients between 18 and 60 years-old fulfilled the inclusion criteria. The main characteristics of patients appear in table 1. Median age of the whole group was 46 years old. Overall survival (OS) in the whole group was 45% at 5 years, being significantly better in AML-03 and AML-12 than in AML-94 and AML-99 (image 1). Event free survival (EFS) in the whole group was 37% at 5 years, with also significant differences between trials. Also, the cumulative incidence of relapse (CIR) was 39% in the whole group with less relapses in the two more recent trials (image 2). To understand these findings, we analyzed first the CR rate over time that was higher in the AML-03 and AML-12 protocols (table 2). The results were different depending on genetics of AML with highest CR rate in patients with CBF AML and in those with intermediate-risk cytogenetics and favorable molecular findings; in contrast, patients with adverse cytogenetics had the lowest CR rate mainly because frequent refractoriness to therapy. According to outcomes in each MRC cytogenetic group 5y-OS was: 69±3% (63-76) in favorable group, 46±2% (43-49) in intermediate and 21±3% (16-27) in adverse group (p & lt;0.001). 5y-EFS was 57±3% (51-64), 38±1% (35-41) and 15±2% (11-20) (p & lt;0.001), and 5y-CIR was 30±3% (24-37), 39±2% (36-43) and 51±4% (43-59) (p & lt;0.001), respectively (table 3). Referent to feasibility of allogeneic HCT, there was an increased access to the procedure over the years. A higher proportion of patients allografted in AML-03 and AML-12, 32% and 41% of patients in CR, respectively, compared to 16% in AML-94 and 19% in AML-99. A shortening of the interval between CR and transplantation has been observed in recent years; 3.9 months (mo) in AML-94, 2.7 mo in AML-99, 2.9 mo in AML-03 and 2.2 mo in AML-12. CONCLUSIONS: In adults with primary AML and age up to 60 years-old have improved over the last 25 years. During this period, the CETLAM group has refined the biological characterization of AML patients and tailored the post-remission therapy based on genetic markers with prognostic impact. The increased feasibility of allogeneic HCT may also justify the better results in more recent trials. Even though, there is substantial room for improvement, particularly in patients with AML and adverse genetic features.

Abstract: Background Cytogenetics at diagnosis is the most important prognostic factor in acute myeloid leukemia (AML). Of note, intermediate cytogenetic risk group (IR-AML) is a very heterogeneous subset including normal karyotypes and all the cytogenetic abnormalities not included in the favorable or the adverse groups. Molecular alterations affecting NPM1, FLT3 and CEBPA show a prognostic impact in IR-AML. MLL partial tandem duplications (MLL-PTD) have also been described in this group of AML, but their prognostic impact have not been well established. Aim To analyze the prognostic relevance of MLL-PTD in the subset of patients diagnosed with IR-AML since 2003, and included in the CETLAM protocols LMA-2003 and LMA-2012. Methods Between 2003 and 2004 MLL-PTD were analyzed by Southern Blot (enzymes employed BglII, EcoRI, BamHI). Since 2004, a long PCR strategy was used to identify this abnormality. Results NPM1 mutations (NPM1mut), FLT3 internal tandem duplications (FLT3-ITD) and MLL-PTD were available for 893 patients. No MLL-PTD was found among 111 and 161 patients of the good and poor cytogenetic risk groups, respectively. The IR-AML group included 621 patients, and 37 carried a MLL-PTD (6%), thus only this cytogenetic group of patients was analyzed. NPM1mut were found in a 41% of patients and none of them had a concomitant MLL-PTD (p 〈 0.001). FLT3-ITD were found in a 31% of patients, and 14 patients had also an MLL-PTD. No correlation between MLL-PTD and age, leukocyte count, and percentage of blasts in bone marrow was found. There was a significant association with gender: men were more frequently mutated than women (29 vs 8; p=0.001). Regarding outcome of IR-AML, leukemia-free survival (LFS) was significantly higher for patients without MLL-PTD (5-year LFS 44±3% vs 18±8%; p 〈 0.001), and overall survival (OS) was also better for this subgroup of patients (5-year OS 42±2% vs 20±7%; p=0.004). There were no differences in the complete response rate, but patients with MLL-PTD had a higher risk of relapse (cumulative incidence at 5 years 39 vs 74%, p=0.000151). Among patients with MLL-PTD, no differences were observed depending on the concurrence of FLT3-ITD. When only patients with NPM1 wild-type were considered, MLL-PTD maintained a significantly poor prognostic impact (36±3% vs 21±7%; p=0.009). Conclusions MLL-PTD is a genetic alteration found in a 6% of IR-AML. Patients with this abnormality have a worse LFS and OS than the rest of patients of the IR-AML group. Based on these results, patients with MLL-PTD should be considered as patients with poor cytogenetic risk AML for treatment allocation. Disclosures No relevant conflicts of interest to declare.

Abstract: Inherited retinal diseases (IRDs), defined by dysfunction or progressive loss of photoreceptors, are disorders characterized by elevated heterogeneity, both at the clinical and genetic levels. Our main goal was to address the genetic landscape of IRD in the largest cohort of Spanish patients reported to date. A retrospective hospital-based cross-sectional study was carried out on 6089 IRD affected individuals (from 4403 unrelated families), referred for genetic testing from all the Spanish autonomous communities. Clinical, demographic and familiar data were collected from each patient, including family pedigree, age of appearance of visual symptoms, presence of any systemic findings and geographical origin. Genetic studies were performed to the 3951 families with available DNA using different molecular techniques. Overall, 53.2% (2100/3951) of the studied families were genetically characterized, and 1549 different likely causative variants in 142 genes were identified. The most common phenotype encountered is retinitis pigmentosa (RP) (55.6% of families, 2447/4403). The most recurrently mutated genes were PRPH2 , ABCA4 and RS1 in autosomal dominant (AD), autosomal recessive (AR) and X-linked (XL) NON-RP cases, respectively; RHO , USH2A and RPGR in AD, AR and XL for non-syndromic RP; and USH2A and MYO7A in syndromic IRD. Pathogenic variants c.3386G  〉  T (p.Arg1129Leu) in ABCA4 and c.2276G  〉  T (p.Cys759Phe) in USH2A were the most frequent variants identified. Our study provides the general landscape for IRD in Spain, reporting the largest cohort ever presented. Our results have important implications for genetic diagnosis, counselling and new therapeutic strategies to both the Spanish population and other related populations.

Abstract: Abstract 1712 The study of chromosome alterations helps to classify acute myeloid leukemia (AML) into three prognostic groups, favorable, intermediate and adverse. The prognostic value of favorable risk and adverse risk abnormalities is well defined; in contrast, the outcome of intermediate-risk group is heterogeneous. Molecular characterization of patients with intermediate-risk AML has identified subcategories with diverse prognosis. All this knowledge has translated into a recent ELN proposal for the genetic classification of AML. Additionally, the intermediate and particularly the cytogenetically adverse groups have been refined by the HOVON group by introducing the concept of “monosomal karyotype” (MK), consisting of at least two autosomal monosomies or one monosomy plus a structural abnormality. Objective: To validate the recent ELN classification in a large series of AML patients and to investigate if the inclusion of MK improved the prognostic stratification. Patients and methods: 804 consecutive patients treated under the CETLAM AML-99 (n=353) and CETLAM-03 (n=451) trials were analyzed. The two protocols included idarubicin, intermediate-dose cytarabine and etoposide as induction and mitoxantrone and intermediate-dose cytarabine as consolidation. G-CSF priming was given in the CETLAM-03 trial. Following, risk-adapted treatment with chemotherapy or hematopoietic transplantation was administered. Parameters analyzed were relapse rate (REL), leukemia-free survival (LFS) and overall survival (OS). Results: Median age of the series was 46 years (range 16–60). Median follow-up of patients alive was 15 months. The ELN classification resulted in different prognostic risk groups. At 5 years, ELN favorable risk category had an OS of 60±4%, intermediate-I of 32±%, intermediate-II of 46±% and adverse of 17±3% (p 〈 0.001). REL was comparable in the intermediate-I and adverse groups, 59±6% and 63±6% respectively, which translated into similar LFS. In contrast to the partial predictive value of the ELN proposal in our series, particularly in the intermediate categories, modified criteria identified 5 significantly different genetic risk groups: a) patients with RUNX1-RUNX1-T1 or CBFB-MYH11, b) patients with CEBPA or NPM1 mutations without FLT3-ITD, c) patients with intermediate cytogenetics of the MRC classification without mutations in CEBPA, NPM1 nor FLT3-ITD, and with FLT3-ITD, d) adverse MRC cytogenetics without MK and, e) patients with MK. Overall survival at 5 years for the 5 groups was 66±5%, 59±5%, 32±4%, 15±5%, and 4±4%, respectively (p 〈 0.001). Conclusion: In the present study, the ELN genetic classification did not discriminate the prognosis of patients in the intermediate-I and intermediate-II categories. In contrast, genetic grouping that considered CBF AML, favorable mutations in the intermediate cytogenetics category and that separated adverse karyotype with or without MK translated into significantly different OS. This classification, together with the study of mutations recently described and the expression of certain genes may contribute to a more precise prognostic stratification and risk-adapted therapy.

Abstract: Abstract 1066 Different approaches have been investigated to improve the prognosis of adult patients with primary acute myeloid leukemia. In two consecutive phase II trials our group has explored the use of intermediate-dose cytarabine in induction associated with idarubicin and etoposide, the addition of G-CSF priming to the previous combination, and risk-adapted postremission therapy. Objective: To compare the results of two consecutive trials for primary AML and to analyze the factors influencing the outcome. Patients and methods: Adult patients between 17 and 60 years of age with de novo AML, diagnosed between 1999 and 2009, were included in the CETLAM AML-99 and AML-03 trials. Induction chemotherapy (CT) included one or two courses of idarubicin 12 mg/m2 IV days 1,3,5, cytarabine 500 mg/m2/12h over 2h IV days 1,3,5,7 and etoposide 100 mg/m2 IV days 1,2,3. This was followed by one consolidation with mitoxantrone 12 mg/m2 IV from day 4 to 6, and cytarabine 500 mg/m2/12h IV from day 1–6. In the AML 03 trial, patients also received G-CSF priming, 150 mg/m2 subcutaneously (SC) from day 0 to the last day of induction and consolidation CT. Postremission therapy consisted of high-dose cytarabine (CBF AML), autologous or allogeneic hematopoietic transplantation depending on cytogenetics, courses to complete remission (CR), and in the AML-03 protocol also based on molecular abnormalities involving FLT3 or MLL genes and/or the persistence of minimal residual disease after consolidation. Results: Overall, 788 patients were included, 353 in the AML-99 trial and 435 in the AML-03. Median age of the patients was 46 years (range 17–60). There were no differences between patients included in the two protocols regarding age, gender, leukocyte counts, cytogenetics and proportion of favourable and unfavourable molecular cases in the group with intermediate-risk karyotype. The main results achieved appear in the table. Multivariate analysis confirmed the favourable impact of AML-03 protocol on outcome. Other significant factors influencing survival were age, leukocyte counts and cytogenetics. Conclusion: G-CSF priming improved the CR rate of adult patients with primary AML and favourable or unfavourable cytogenetics. This fact and a more precise risk-adapted therapy taking into account genetic data and MRD studies translated into improved overall survival.

Abstract: The microcystic, elongated and fragmented pattern of invasion can be associated with an underestimation of the depth of myometrial invasion by imaging techniques. We aimed to evaluate the influence of microcystic, elongated and fragmented pattern of invasion in the diagnostic performance of transvaginal ultrasound scan and magnetic resonance imaging for the prediction of the depth of myometrial invasion in low-grade endometrioid endometrial carcinomas. Methods: Prospective and consecutive study including all low-grade (G1-G2) endometrioid endometrial carcinomas diagnosed between October 2013 and July 2018 in a tertiary hospital. Preoperative staging was performed with transvaginal ultrasound scan and/or magnetic resonance imaging followed by surgical staging. Final histology was considered as the reference standard. Sensitivity, specificity and diagnostic accuracy for the prediction of depth of myometrial invasion was calculated for both imaging techniques. The STARD 2015 guidelines were used. Results: A total of 136 patients were consecutively included. Transvaginal ultrasound scan was performed in 132 patients and magnetic resonance imaging in 119 patients. The diagnostic accuracy of transvaginal ultrasound scan for the prediction of depth of myometrial invasion in the microcystic, elongated and fragmented negative group (82% (95% confidence interval = 73–88)) was higher compared to the microcystic, elongated and fragmented positive group (61% (95% confidence interval = 36–83)). The diagnostic accuracy of magnetic resonance imaging was also higher in the microcystic, elongated and fragmented negative group (80% (95% confidence interval = 71–87)) compared to the microcystic, elongated and fragmented positive (47% (95% confidence interval = 21–73)). Conclusions: In low-grade endometrioid endometrial carcinomas with a positive microcystic, elongated and fragmented pattern of invasion, the evaluation of the depth of myometrial invasion using transvaginal ultrasound scan and magnetic resonance imaging may be underestimated.

Abstract: Introduction The European LeukemiaNet (ELN) 2017 classification for acute myeloid leukemia (AML) stratifies patients in 3 risk categories, according to genetic features of the disease. ELN classification is commonly used to guide post-remission treatment; favorable risk patients do not seem to benefit from allogeneic hematopoietic transplantation (alloHCT) in first complete remission (CR1) while this procedure is highly recommended in adverse risk patients. Post-remission treatment in intermediate risk patient is still debated. This classification has not been prospectively validated. Herein we analyze the prognostic impact of ELN 2017 classification in patients treated with the same protocol (CETLAM-12), including a well-defined preplanned alloSCT policy according to genetic risk. Methods We analyzed characteristics and outcome of patients diagnosed with de novo AML, included in CETLAM-12 protocol for patients up to 70 years, with an available genetic characterization at diagnosis allowing an accurate ELN 2017 stratification. Genetic risk allocation was based on cytogenetic analysis and pre-specified RT-PCR of determined markers (including CBF-rearrangement, NPM1, FLT3, CEBPA, and MLL-PTD) performed in all patients, and targeted Next Generation Sequencing testing (available in 143 patients). CETLAM-12 protocol defines a genetic risk stratification in three groups, closely similar to that proposed by the ELN 2017 classification, and recommends a post-remission strategy based on this risk assessment. Patients from the favorable group received three courses of consolidation with high-dose cytarabine (HiDAC), whereas alloSCT in CR1 is strongly recommended for intermediate and adverse risk patients following one HiDAC-based consolidation course. Results We included in the study 813 patients (400F/413M; median age 56, 17-76); with a 37 months median estimated follow-up (range 0.1-92). The outcomes of the entire cohort are shown in table 1. Out of all patients, 641 could be classified according to the ELN 2017 classification, due to the presence of risk defining genetic features identified by any of described methods. In the group of .atients allocated in the favorable risk category (n=316; 49%), twenty-seven patients died during induction. Fifty-eight relapses were observed, mostly in patients with NPM1 mutation (n=41). AlloSCT was finally performed in CR1 in 84 patients (27%) due to MRD persistence or reappearance (n=40), overt hematological relapse (n=27), persistent aplasia following chemotherapy (n=3) and protocol deviation (n=14). In the group of patients allocated in the intermediate risk category (n=95; 15%), twelve patients died during induction. AlloSCT in CR1 was performed in 62 patients (67%), with 5 patients receiving an alloSCT in CR2. In the group of patients allocated in the adverse risk category (n=230; 36%), twenty-five patients died during induction. AlloSCT could be finally performed in CR1 in 138 patients (60%) and 88 relapses occurred (42 before alloSCT, 46 after alloSCT). Amongst ELN adverse risk patients, a subgroup with a significant worse outcome has been identified, defined by AML with complex karyotype +/- TP53 mutation or chromosome 3q26/MECOM-GATA2 rearrangement. This group (ELNadv+) presented a lower CR rate, with a higher relapse rate and fewer proportion of patients who receive a pre-planned alloSCT in CR1. OS and EFS of ELNadv+ is significantly lower than ELN adverse patients. In the multivariate analysis for OS including age, sex, WBC count at diagnosis and number of cycles to achieve CR, only age and ELNadv+ status showed independent prognostic value. Outcome data is summarized in table and figures attached. Conclusions The initial risk-adapted post-remission assignment planned in CETLAM-12 could be performed in the majority of patients. Despite this different proposed post-remission treatment, ELN risk classification was able to identify three groups of patients with a markedly different outcome. Interestingly, within the unfavorable ELN category, a very high-risk ELNadv+ subgroup can be distinguished, with a dismal outcome with current approach, warranting the implementation of innovative pre and post-transplant strategies aimed to prevent treatment failure.
