Exploratory multicenter, non-interventional, translational, retrospective and prospective study. All patients with a diagnosis of hematologic disorder or malignancy for whom biological samples and clinical data are available may be included in this study, after obtaining informed consent

Hematological malignancies account for approximately 9.5% of newly diagnosed cancers every year and their incidence shows an exponential rise after the age of 40. Since life expectancy is dramatically and continuously increasing worldwide, hematological diseases promise to become a substantial burden for the health care systems of the European society. The management of hematological malignancies is further complicated by the high level of disease heterogeneity in terms of pathogenic and molecular mechanisms. Due to the high level of heterogeneity in terms of cytogenetic, genetic, epigenetic, transcriptional, post-transcriptional and metabolic alterations, an accurate molecular classification of hematological diseases is needed to improve clinical outcomes and patients' management. This is an exploratory multicenter, non-interventional, translational, retrospective and prospective study. All patients with a diagnosis of hematologic disorder or malignancy for whom biological samples and clinical data are available may be included in this study, after obtaining informed consent. The primary objective is to improve our knowledge of the pathogenic mechanisms driving malignant disorders and transformation. The secondary objectives aim to improve diagnosis and stratification of onco-hematological patients and study drug response at preclinical level. After signing informed consent to the study, each patient will donate part of the samples (peripheral blood, bone marrow, biopsies) collected as per routine clinical practice for the management of their disease.

Inclusion Criteria:

1. Participant is willing and able to give informed consent for participation in the study
2. Male or Female, aged >18 years
3. Patients with histologically confirmed diagnosis of one of the following haematological diseases: monoclonal gammopathy of undetermined significance (MGUS), idiopathic cytopenia of undetermined significance (ICUS), clonal cytopenia of undetermined significance (CCUS), clonal hematopoiesis of indeterminate potential (CHIP) or hematological malignancies: Peripheral T-cell Lymphomas (PTCL), B- and T-Lymphoblastic Leukemias / Lymphomas (ALL), Burkitt Lymphoma (BL), B and T cell lymphoma, Acute Myeloid Leukemia (AML), Myeloproliferative Disease (Polycythemia Vera (PV), Essential Thrombocythemia (ET), Monocytic Leukemia), Chronic Lymphocytic Leukemia (CLL), Chronic Myeloid Leukemia (CML), Myelofibrosis, Myelodysplasia (MDS) including Macrocytic Anemia, Sideroblastic Anemia and Non-Neoplastic Hematologic Disease, Systemic Mastocytosis, Multiple Myeloma (MM), Plasma Cell Disease.
4. Available clinical data (demographics including ethnicity, stage of disease, concise treatment history, cytogenetic reports, and molecular data if available, as routinely performed during diagnosis procedures);
5. For the retrospective part of the study: availability of biological samples collected for routine diagnostics/therapeutic procedures and stored as appropriate, per laboratory standard procedures.

Exclusion Criteria:

• Patients included in clinical trials may be enrolled in this explorative study, except where otherwise clearly indicated in the experimental protocol

Patients diagnosed with haematological malignancy or disorder (see inclusion criteria) treated in the participating centers will be considered for enrollment. Patients can be enrolled at diagnosis or at relapse. Samples will be collected before treatment, during treatment whenever possible, at follow-up, at remission and at each relapse.
