Myelodysplastic syndromes
Lionel Adès Hopital Saint Louis , Paris Diderot University
French MDS group
Disease characteristics
MDS
• Clonal myeloid disorders
– Ineffective hematopoiesis leading to cytopenias
– Progression to AML in 30-35% of cases
• Predominance in the elderly
• Etiology generally unknown
Incidence and prevalence of myelodysplastic syndromes
• Crude incidence rate - 4.15/100,000/year • Point prevalence - 7 per 100,000 persons • Incidence and prevalence of MDS higher in men than women • Increased sharply with increasing age.
Data from the Düsseldorf MDS-registry. (Neukirchen J, 2011)

Etiology of MDS
Exogenous factors in MDS (15% of the cases)
• Chemotherapy
– Alkylating agents
– Purine analogs
– Cisplatin
• Radiotherapy
• Environmental factors
– Benzene
– Tobacco smoke
Kiran Tawana and Jude Fitzgibbon, Blood 2016
Inherited factors in MDS (2-3% of adult cases)
HMs alone
associated bone marrow failure syndromes
Cytopenias and/or platelet dysfunction

• 289 Families with familial Myeloid malignacies
– DDX41 Mutations in 3%
• DDX41 mutation screening (NGS)

Significant association of SF3B1
mutations with the presence of
ring sideroblasts.
SF3B1 mutations were found to
be independently associated
with better overall survival
(HR=0.15, P=.025) and lower
risk of evolution into AML
(HR=0.33, P=.049).

pendent patient-related prognostic parameters suited todeveloping a prognostic model. In the multivariate analy-sis of overall survival in 107 patients, only impairments inperformance status, in activities of daily living (ADL) andthe symptom item ‘fatigue’ from the EORTC QOL-C30were retained as independent prognostic factors of overallsurvival, in addition to the know n MDS/AML-related riskfactors poor risk cytogenetics/IPSS and bone marrow
blasts of 20% or over. Therefore, the basic informationreflecting a patient's functionality (KI, ADL) and QOLstrongly indicate vulnerability and complement the keyclinical parameters that have until now influenced treat-ment decision-making (i.e. numerical age, percentage ofblast or cytogenetics). Impairments in the more sophisti-cated parameters (IADL, MMSE, ‘Get-Up-and-Go Test’)may on the contrary represent a distinct individual state

pendent patient-related prognostic parameters suited todeveloping a prognostic model. In the multivariate analy-sis of overall survival in 107 patients, only impairments inperformance status, in activities of daily living (ADL) andthe symptom item ‘fatigue’ from the EORTC QOL-C30were retained as independent prognostic factors of overallsurvival, in addition to the known MDS/AML-related riskfactors poor risk cytogenetics/IPSS and bone marrow
blasts of 20% or over. Therefore, the basic informationreflecting a patient's functionality (KI, ADL) and QOLstrongly indicate vulnerability and complement the keyclinical parameters that have until now influenced treat-ment decision-making (i.e. numerical age, percentage ofblast or cytogenetics). Impairments in the more sophisti-cated parameters (IADL, MMSE, ‘Get-Up-and-Go Test’)may on the contrary represent a distinct individual state

BEST SUPPORTIVE CARE HYPOMETHYLATING AGENT
Geriatric assement in AML/MDS

estimate and communicate degrees of dependence,emerges in this study as having additional value in objec-tifying decision-making processes. In agreement w ith this,a recent investigation on the impact of a geriatric assess-ment in treatment decision-making in elderly patientsrevealed that the ADL’s value correlates w ith treatmentallocation (non-intensive care vs. intensive treatmentefforts).37
Several studies have shown baseline QOL parameters tobe independent prognostic factors in different malignan-cies42-45 underscoring the assumption that QOL scales addprognostic information to clinical measures and predictsurvival.46 Patient ratings of physical symptoms (i.e.‘fatigue’), physical functioning and global healthstatus/QOL have repeatedly been the best predictors ofsurvival.45,47 In this context, Oliva et al. reported a study onelderly AML patients in which QOL physical functioningwas of prognostic relevance yet, somewhat surprisingly,did not correlate to the physician-assessed ECOG per-formance status.48 While the item ‘fatigue’ has beenshown to be prognostically relevant in several differentmalignant diseases,47,49-51 so far only hypotheses to explainthe mechanisms underlying the association betw eenreported data on patient health status and duration of sur-vival have been proposed.52 ‘Fatigue’ is a patient-reported
outcome and multi-faceted concept including both mentaland physical components whose critical domains have notbeen sufficiently standardized and for which several scaleshave been developed.53 Despite these shortcomings, webelieve that further investigation of this extremely debili-tating symptom observed in many if not all cancerpatients is useful for optimizing patient care.
When comparing our score to established risk assess-ment scores (i.e. comorbidity score by Sorror, risk indexby Wheatley), we found that, despite some associations,independent and complementary information could beobtained. We, therefore, suggest that the scores do actual-ly measure different aspects of patient- and disease-specif-ic factors. Possibly, the estimation of functionality mightdisplay an increasing relevance in patients treated non-intensively who are, on average, older, while parameterscalculated in the established scores may be even more rel-evant in younger, intensively treated patients. Future stud-ies may reveal whether the scores can complement eachother.
Our study has several limitations. First, the assessmentswere all performed by a small number of trained physi-cians raising the possibility that a bias could have beenintroduced. However, the instruments were, wheneverpossible, patient self-administered. Second, our patient
