IPSS-R: Prognostic Risk Categories/Scores. More than half of the patients from the IPSS-R intermediate category shifted, including 18% who were upstaged to IPSS-M very-high. 16) aged at least 18 years in the IPSS-R very low- to intermediate-risk groups at screening, and who had anemia with baseline hemoglobin of 10.0 g/dL or less (average of two baseline measurements and transfusion free for at least 1 week) with or . Malcovati L, Germing U, Kuendgen A, et al. The DIPSS plus score further refines the prior prognostic scoring system with the addition of DIPSS-independent risk factors, including karyotype, transfusion dependency and platelet count. 1. When comparing the prognostic value of the International Prognostic Scoring System (IPSS), WHO Prognostic Scoring System (WPSS), and IPSS-R, . • IPSS-R Very low-, Low-, or Intermediate-risk • Prior ESA response - Refractory, intolerant - ESA naive: EPO > 200 U/L • Average RBC transfusion burden ≥2 U/8 weeks • No prior treatment with disease-modifying agents (e.g. Outcomes and clinical interventions for patients with IPSS-R int-risk are … 7% of patients were shifted by ≥2 risk strata. On review, the clinical outcome data indicate that the IPSS-R Intermediate . If your IPSS score is 0, you are in the low-risk group. R-IPSS high-risk or very-high-risk patients regardless of transfusion frequency or intermediate-risk patients with high transfusion needs (> 2 U RBCs per month) Patients who are good candidates for high-intensity therapy (ie, young patients with few or no comorbidities, good performance status, and adequate psychosocial support): The IPSS-R is an alternative prognostic risk scoring system that takes into account additional cytogenetic data compared to the IPSS. Intermediate-risk IPSS-R group disclose a clinical outcome resembling more HR-MDS than LR-MDS. These findings have relevant clinical implications, as they imply that intermediate-risk patients should be managed as high-risk MDS. IPSS-R is more refined in its prognostic precision and includes five instead of four prognostic groups. If your IPSS score is 0.5 to 1, you are in the intermediate-1 risk group. Moreover, patient #4, #18, and #41 were classified into low-risk and patients #36 and #44 were intermediate-risk based on IPSS-R, who eventually died as they only received supportive care. IPSS-R karyotype Low High Intermediate 4.5 1.4 3.3 1.2 6.1 1.7 <0.0001 0.0001 Age > 60 years 2.0 1.5 2.6 <0.0001 To determine an age-adjusted risk categorization, for example, follow the horizontal line, starting at the IPSS-R risk score 3.5 on the vertical axis (Int [Intermediate] risk category per Table 4 . Lenalidomide in International Prognostic Scoring System Low and Intermediate-1 risk myelodysplastic syndromes with del(5q): an Italian phase II trial of . Based on the National Comprehensive Cancer Network guidelines, iron chelation is recom- mended for patients with IPSS-R low- and intermediate-1 risk MDS with a history of more than 20 to 30 RBC transfusions, when the ferritin is above 2500 ng/mL using either deferasirox or deferoxamine. Kaplan-Meier analysis showed that overall survival (OS) curves of the five risk categories stipulated by the revised international prognostic scoring system (IPSS-R) were reasonably separated. . Greenberg P., et al. Blood. Lower-risk patients (conventionally defined as International Prognostic Scoring System (IPSS) low-risk and intermediate-1-risk groups) who have failed to respond or have ceased responding to ESAs may be treated with one of several disease-modifying agents. This is a phase 1/2 study to evaluate the combination of vadastuximab talirine (SGN-CD33A; 33A) and azacitidine in subjects with previously untreated International Prognostic Scoring System (IPSS) Intermediate-2 or high risk myelodysplastic syndrome (MDS). The impact of this practice on survival in lower-risk patients is unknown. The training cohort of 63 MDS patients was conducted at Zhongda Hospital of Southeast University from January 2013 . High risk. For intermediate risk and for some patients with low risk additional poor risk factors such as life-threatening cytopenias, high transfusion burden, poor risk cytogenetics/molecular characteristics and blast increase may indicate a need for an early SCT. Naval Daver, MD: Each year, of all the patients with MDS [myelodysplastic syndrome] in the United States, about 55% to 60% will present with a higher-risk MDS. 5)/high/very high-risk groups) or AML with 20-30% blasts. Intermediate-risk patients have an IPSS-R score of 3 to 4.5 points. Disparity in perceptions of disease characteristics, treatment . Dec. 3, 2015: fast track status for treatment of anemia in persons with IPSS-R lower risk (very low, low, intermediate risk) myelodysplastic syndrome granted She outlined strategies for dosing, administration, and . The Guideline group foresee that large ongoing clinical trials and sequencing projects will add to the knowledge about these patients. This score is not dynamic and is meant to be used at the time of diagnosis only. The International Prognostic Scoring System (IPSS)57 divides patients into low, intermediate-1 (INT-1), intermediate-2 (INT-2), and high categories ( Table 93-5 ). 536) Versus Placebo For The Treatment Of Anemia Due To IPSS-R Very Low, Low, Or Intermediate Risk Myelodysplastic Syndromes In Subjects With Ring Sideroblasts Who . The . Very high risk. The level of red blood cells (measured as hemoglobin) in the patient's blood. Using the IPSS revised system, which is called IPSS-R, median time until 25% of the MDS population developed AML is greater than 14 years for very low-risk, by 11% for low-risk patients, 3% for intermediate, 1.4% for high-risk, and 0.7% for very high-risk patients. IPSS-R (Revised International Prognostic Scoring System, Greenberg et al, 2012) Definition of the IPSS-R. . A, Distribution of intermediate-favorable (int-fav) and intermediate-adverse . ): IPSS-R Prognostic Risk Categories/Scores and Clinical Outcomes. However, among patients ≤65 years, 33% of those in the intermediate-risk category received SCT, whereas only less than 12.5% of those . This heterogeneity can be partly resolved by the use of molecular genetic sequencing. The type and number of chromosome abnormalities in the cells. • Risk of Progression • IPSS, IPSS-R and now IPSS-RM • Predictive • Response to chemo/BMT (DNMT3a, p53) • MRD • Targeted therapies Revised International Prognostic Scoring System (IPSS-R) for Myelodysplastic Syndromes Risk Assessment Calculator . Patients with lower-risk (low/intermediate risk according to IPSS-R) myelodysplastic syndrome (LR-MDS) account for approximately two-thirds of patients with . Patients in low, intermediate-1, intermediate-2, and high risk were assigned 0, 1, 2, and 3 points, respectively. The IPSS-M resulted in restratification of 46% of patients. Patients with "higher-risk" disease — defined as intermediate, high or very high on the IPSS-R scale - account for 43% of people diagnosed with MDS. Physicians should also consider other factors that can refine the prognosis predicted by the IPSS-R. For intermediate-risk patients near the border of lower- versus higher-risk disease, greater lactate dehydrogenase, ferritin, and bone marrow fibrosis have been shown to carry increased risk. Patients with IPSS-R Intermediate risk need special consideration. Score: Risk groups: 0: Very low risk: 1: Thus, by using this cut-off most of the intermediate IPSS-R MDS patients are indeed considered as higher risk. Intermediate-risk patients have an IPSS-R score of 3 to 4.5 points. 6-7 Remaining within the IPSS-R Intermediate category are those who, indeed, have "intermediate" risk (Tables 5 and and7). The revised International Prognostic Scoring System (IPSS-R) classifies patients into five groups, which include very low risk, low risk, intermediate risk, high risk and very high risk. The low and intermediate categories are sometimes combined into a lower risk group; the intermediate-2 and high categories are sometimes combined into a higher risk group. The objective response rate for all 77 patients treated with 5-azacitidine was 23%, with ORR of 21% for IPSS-R intermediate, 17% for IPSS-R high, and 38% for IPSS-R very high. Greenberg PL, Tuechler H, Schanz J, et al. The score was developed and validated by Gangat et al. Integrating the MDS FISH panel cytogenetics (IPSS + FISH restaging) resulted in upstaging the score, where 53% of low-risk IPSS were upstaged to intermediate (int)-1, 56% of int-1 were upstaged to int-2, and 78% of int-2 were upstaged to high risk. Dr Rami stated that this is often a decision that is individualized based on the patient. With regard to the IPSS-R categories, 10%, 72%, and 17% of the patients had a myelodysplastic syndrome defined as being of very low risk, low risk, and intermediate risk, respectively. . Very low, low or intermediate risk disease MDS with up to 3.5 points according to the revised International Prognostic Scoring System (IPSS-R) classification (to be confirmed during screening assessment). This was defined as 75% accuracy predicting OS of 30 months or longer. A revised IPSS, IPSS-R was published in 2012. The level of platelets in the patient's blood. Based on these variables, an overall score is calculated. A revised IPSS, IPSS-R was published in 2012. However, few risk signatures which integrate the revised international prognostic scoring system (IPSS-R) with gene mutations can be easily applied in the real world. The revised International Prognostic Scoring System (IPSS-R) was recently developed to better assess the clinical outcome of adult patients with myelodysplastic syndrome (MDS). Thus, by using this cut-off most of the intermediate IPSS-R MDS patients are indeed considered as higher risk. The Revised International Staging System (R-ISS) includes variables included in the original ISS (serum beta-2 microglobulin and serum albumin), while also including the additional prognostic information obtained from serum LDH and high-risk chromosomal abnormalities detected by interphase fluorescent in situ hybridization (iFISH) after CD138 plasma cell purification. Dr Rami stated that this is often a decision that is individualized based on the patient. Deciding how to deal with a patient who falls within the intermediate risk category can be a difficult decision. If your IPSS score is more than 2.5, you are in the high-risk . Schanz J, et al. In treatment cycle 1, the median total dose of lenalidomide was 210, 180 and 155 mg for the IPSS-R low-, intermediate- and high-risk groups, respectively, due to dose interruption and dose reduction. Further, patients #5, #32, #34, #48, and . It is based on the number of cytopenias (hemoglobin level of less than 10 g/dL, an absolute neutrophil count of less than 1500/μL, and a platelet count of less than 100,000/μL . 2. intermediate-1; intermediate-2; high; The two lower categories can be further described as the lower risk group while the two upper categories can be further described as the higher risk group. The IPSS-R categorizes patients into 1 of 5 groups, from very low risk to very high risk, based on risk of mortality and transformation to acute myeloid leukemia (AML). In this study, we aimed to investigate the prognostic impact of this new risk model on 555 MDS patients in Taiwan. Grade 1A (on the basis of a single randomised control trial). Currently, revised International Prognostic Scoring System (IPSS-R) was regarded as the dominant prognostic scoring system which is based on a comprehensive cytogenetic scoring system . The IPSS-R, which is the most commonly used scoring system, is a refinement of the original International Prognostic Scoring System (IPSS) based on a much larger clinical database (N=7012). In other words, the "better risk" IPSS Intermediate-1 patients have been categorized into the lower-risk IPSS-R category; the "poorer risk" IPSS Intermediate-2 patients are now in the higher-risk IPSS-R category. IPSS-R high and very high risk. . The European LeukemiaNet and the American NCCN MDS practice guidelines recommend treatment based on the IPSS-R, age and performance status.83 9 The IPSS-R has been confirmed to be a valuable method for risk-classifying MDS patients, albeit with some degree of variablity.88 84. The mutation combined with re-vised international prognostic scoring system (MIPSS-R) was developed based on the results derived from multi-variate analysis which assigned points to the IPSS-R and In the survival analysis, the IPSS and IPSS-R risk classification systems along with the ECOG PS and SF levels > 520 ng/ml . Validation of the revised international prognostic scoring system (IPSS-R) in patients with lower-risk myelodysplastic syndromes: a report from the prospective European LeukaemiaNet MDS (EUMDS) registry Revised international prognostic scoring system for myelodysplastic syndromes. Evaluation of IPSS-Revised (IPSS-R) Cytogenetic Risk Stratification and Prognostic Impact of Monosomal Karyotype in 1,014 Patients with Myelodysplastic Syndromes (MDS) . RISK CATEGORY. Intermediate: del(7q), +8, +19, i(17q), any other single or double independent clones: Poor-7, inv(3)/t(3q)/del(3q), double including -7/del(7q), Complex: 3 abnormalities: The DIPSS was proposed and validated by Passamonti et al to estimate prognosis in myelofibrosis. sified into high-risk. If . Low: 5.5 years with a 14% risk of AML; Intermediate: 4 years . Validation cohort. In our center the IPSS . If your IPSS score is 1.5 to 2, you are in the intermediate-2 risk group. Outcomes and clinical interventions for patients with IPSS-R int-risk are not well defined. High >4.5-6. Open in figure viewer PowerPoint. Generally, IPSS-R high and very high risk can be treated as IPSS intermediate-2 and high risk. A treatment plan is designed around the patient's score and the doctor's personal observations of the patient. Remaining within the IPSS-R Intermediate category are those who, indeed, have "intermediate" risk (Tables 5 and 7). A randomized phase 3 study of lenalidomide versus placebo in RBC transfusion-dependent patients with low-/intermediate-1-risk myelodysplastic syndromes with del5q Blood 118: . These findings have relevant clinical implications, as they imply that intermediate-risk patients should be managed as high-risk MDS. Note: Earlier IPSS was used based on BM . The majority (74%) were upstaged and 26% were downstaged. Our study confirms that intermediate-risk IPSS-R may be considered as lower-risk if the score is 3.5 versus higher-risk if the score is >3.5. 6, 7 2-year OS rates for the very low-, low-, intermediate-, high-, and very high-risk categories were 95, 89, 79, 35, and 12%, respectively. A Phase I/II, Open-label Study to Investigate the Pharmacokinetics, Safety, and Efficacyof ATG 016 Monotherapy in IPSS-R Intermediate Risk and Above Myelodysplastic Syndrome (MDS) Patients After Failure of Hypomethylating Agent (HMA)-Based Therapy: Estimated Study Start Date : June 30, 2021: Estimated Primary Completion Date : December 7, 2023 It divides patients into five categories including an intermediate subset (IPSS-R int-risk). The International Prognostic Scoring System-Revised (IPSS-R) is one standard for myelodysplastic syndrome (MDS) risk stratification. The intermediate risk IPSS-R group is heterogeneous, with some patients having a more indolent natural history similar to lower risk MDS and others more aggressive disease. The score was developed and validated by Gangat et al. These patients might receive more intensive therapy and would expect a better prognosis based on MIPSS-R suggestion. These results support the idea that Japanese patients with MDS with the IPSS-R intermediate-risk category should be regarded as the lower risk MDS together with those in the low- and very low-risk categories. The majority of patients with MDS have IPSS-R very low- to intermediate-risk disease at diagnosis 1. . It should be noted, however, that the total lenalidomide dose received and duration of treatment differed across the IPSS-R risk groups. IMiD agents, HMAs) Randomized 2:1 Figure 2. intermediate-1; intermediate-2; high; The two lower categories can be further described as the lower risk group while the two upper categories can be further described as the higher risk group. The treatment strategies for Myelodysplastic Syndromes (MDS) are usually based on the risk stratification system. The purpose of this study is to determine the effectiveness of luspatercept (ACE-536) compared to epoetin alfa on red blood cell (RBC) transfusion independence (for at least 12 weeks) with a concurrent hemoglobin increase of at least 1.5 g/dL in participants with anemia due to revised international prognostic scoring system (IPSS-R) very low, low, or intermediate risk myelodysplastic syndromes . The DIPSS was proposed and validated by Passamonti et al to estimate prognosis in myelofibrosis. Patients with scores ≤4.5 fall into lower-risk categories (very low, low, and intermediate risk). The revised International Prognostic Scoring System (IPSS-R) groups people with MDS into five categories that it bases on risk: . Very High >6. It was created by examining 7012 MDS cases from the United States and Europe. 8,91-93 Conversely, greater time since diagnosis may . We generally consider, using the IPSS-R [Revised International Prognostic Scoring System], anybody who has intermediate, high, or very high, any of those 3 categories, to be among the higher-risk MDS population. The DIPSS plus score further refines the prior prognostic scoring system with the addition of DIPSS-independent risk factors, including karyotype, transfusion dependency and platelet count. The International Prognostic Scoring System (IPSS) revised version (IPSS-R), Eastern Cooperative Oncology Group Performance Status (ECOG PS) (0 or 1 versus ⩾2) and baseline serum ferritin (SF) levels > 520 ng/ml were shown to independently predict response to 5-AZA. The International Prognostic Scoring System-Revised (IPSS-R) is one standard for myelodysplastic syndrome (MDS) risk stratification. High risk. Univariate analysis revealed that age was a factor in primary thrombosis risk (P = .026), as was low IPSS score (P = .020) and JAK2-positivity (P = .002), said Barbui."Interestingly, among patients with primary MF, those patients in the low and intermediate-1 categories had a 63% risk of thrombosis, but those in the high or intermediate-2 risk only had a 37% risk. In 2012, a revised IPSS (IPSS-R) was released with five risk groups (very low, low, intermediate, high and very high). In treatment cycle 1, the median total dose of lenalidomide was 210, 180 and 155 mg for the IPSS-R low-, intermediate- and high-risk groups, respectively, due to dose interruption and dose . Intermediate risk. Objective: This study aimed to explore the prognostic value of the revised international prognostic scoring system (IPSS-R) and the WHO prognostic scoring system (WPSS) in patients with myelodysplastic syndrome (MDS) undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods: The clinical data of 184 patients with MDS who received allo-HSCT from July 2016 to June 2019 . 2012;120(12):2454-2465. We performed an analysis of . 2012;120(12):2454-2465. Six percent of patients from the IPSS-R very-low/low stratification shifted to IPSS-M very-high/high. Intermediate >3-4.5. >50% of those in the IPSS-R intermediate risk group were restratified, with 11% upstaged to very high by IPSS-Molecular. That being said, the score does get higher with disease progression. . MDS Staging: Revised International Prognostic Scoring System . The researchers found that the IPSS-R cutoff that best identified low-risk disease was 3.5 or lower. Limited numbers of IPSS-R intermediate-risk patients were IPSS low-risk (n = 4) or IPSS high-risk (n = 7) (Supporting Information Figure S1). This approach shows how the addition of gene mutations to current prognostic models can improve their predictive power without necessarily having to alter . 2012 Blood 120: 2454-2465. 7). Around 20% of MDS patients fall in the intermediate category, with a median . It was developed by the International Working Group for the Prognosis of MDS (IWG-PM) under the aegis of the MDS Foundation. (AML) takes 10.8 years; intermediate risk patients have a median survival of 3.0 years and 3.2 years for AML transformation; high risk patients have a . People with MDS who have a lower IPSS-R score have the best outlook for survival and need less aggressive . Oliva EN, Latagliata R, Laganà C, et al. The IPSS-R category determines patient Survival (based on Revised International Prognostic Scoring System (IPSS-R) for Myelodysplastic Syndromes. Revised international prognostic scoring system for myelodysplastic syndromes. Decision making: Genomics in the International Prognostic Scoring System risk assessment On review, the clinical outcome data indicate that the IPSS-R Intermediate . International Prognostic Scoring System (IPSS) This is the most commonly used prognostic scoring system. Intermediate-risk IPSS-R group disclose a clinical outcome resembling more HR-MDS than LR-MDS. IPSS classification of test cohort and survival of external validation cohorts. Blood. In the current sample, that equated 2,830 patients (69%) with low-risk disease and 1,273 (31%) with high-risk disease, with median OS rates of 75 months and 15.4 months . Blood 2012;120:2454-65. . The revised International Prognostic Scoring System (IPSS‐R) was recently developed to better assess the clinical outcome of adult patients with myelodysplastic syndrome (MDS). Greenberg PL, Tuechler H, Schanz J et al. From a practical standpoint, this lends support to the . IPSS uses three "prognostic indicators" to predict the course of the patient's disease: The percentage of leukemic blast cells in the marrow. into IPSS-R could further stratify MDS patients with higher-risk IPSS-R (intermediate, high and very high risk) into four groups, rather than three groups, with . For MDS/MPN < 10% bone marrow blasts at screening. Low and Intermediate-1 risk categories are together considered lower-risk MDS. Intermediate risk = all other aberrations 5) at least 1 transfusion every 8 weeks over a period of 3 months . WPSS-prognostic risk categories. Around 20% of MDS patients fall in the intermediate category, with a median . It refined the original model by incorporating more detailed cytogenetic prognostic categorization and cut-offs for hemoglobin levels, platelet counts and neutrophil count. The revised International Prognostic Scoring System (IPSS-R) is based on 5 factors: The percentage of blasts (very early forms of blood cells) in the bone marrow. J Clin Oncol. Finally, combining molecular data with the IPSS-R, 26% of patients were upstaged to higher-risk disease including 62% of patients with intermediate risk who moved to a higher-risk category. Remaining within the IPSS-R Intermediate category are those who, indeed, have "intermediate" risk (Tables 5 and 7). Based on the R-IPSS, 61% of very low-risk patients, all low-risk patients, 92% of intermediate . Generally, the IPSS‐R could discriminate MDS patients regarding risk of leukemia evolution and .
