Validation of the revised international prognostic scoring system (IPSS-R) in patients with myelodysplastic syndrome: a multicenter study.

2013

The revised IPSS (IPSS-R) was developed aiming at a better prognostication, taking into account patients treated with best supportive care. We herein validated this model on the basis of data from 1314 patients who received BSC only as well as patients who underwent induction chemotherapy (n=214) or allogeneic transplantation (n=167). We could demonstrate a clear distinction of the IPSS-R risk categories with regard to survival and risk of AML evolution in all patient cohorts. When comparing IPSS-R, IPSS, WHO prognostic scoring system (WPSS) and Duesseldorf score, the best results regarding the ability to predict survival were obtained by the IPSS-R.

Aggressive chemotherapy combined with G-CSF and maintenance therapy with interleukin-2 for patients with advanced myelodysplastic syndrome, subacute …

1993

Aggressive chemotherapy of advanced myelodysplastic syndrome (MDS), acute myeloid leukemia (AML) evolving from MDS, subacute AML and secondary AML has usually been associated with low complete remission (CR) rates, a high incidence of early death, and low disease-free survival. We therefore have initiated a phase-III trial of aggressive chemotherapy consisting of idarubicin, cytosine arabinoside, and VP-16 to improve the CR rate. Each chemotherapy cycle is followed by G-CSF to accelerate neutrophil recovery and to reduce the incidence of infections. Until now, 19 patients with high-risk AML have been entered. The CR rate is 47%, with only one death during induction. Patients achieving CR ar…

Differential impact of allelic ratio and insertion site in FLT3-ITD-positive AML with respect to allogeneic transplantation.

2014

The objective was to evaluate the prognostic and predictive impact of allelic ratio and insertion site (IS) of internal tandem duplications (ITDs), as well as concurrent gene mutations, with regard to postremission therapy in 323 patients with FLT3-ITD-positive acute myeloid leukemia (AML). Increasing FLT3-ITD allelic ratio (P = .004) and IS in the tyrosine kinase domain 1 (TKD1, P = .06) were associated with low complete remission (CR) rates. After postremission therapy including intensive chemotherapy (n = 121) or autologous hematopoietic stem cell transplantation (HSCT, n = 17), an allelic ratio ≥ 0.51 was associated with an unfavorable relapse-free (RFS, P = .0008) and overall survival …

Chromosomal abnormalities in women with breast cancer after autologous stem cell transplantation are infrequent and may not predict development of th…

2000

We determined prospectively the incidence of chromosomal abnormalities in patients with high-risk breast cancer (HRBC) after high-dose chemotherapy (HDCT) and autologous stem cell transplantation (ASCT), and correlated the cytogenetic abnormalities with the development of post-transplant myelodysplastic syndrome or acute myeloid leukemia (MDS/AML). From 1990 to 1999, 229 women with HRBC underwent ASCT. Cytogenetic analysis of bone marrow (BM) cells was performed 12–59 months after ASCT in 60 consecutive women uniformly treated with six courses of FAC/FEC followed by HDCT and ASCT. With a median follow-up of 36 months after ASCT, there were no cases of MDS/AML among the 229 patients. In the …

Residual Abdominal Lymphadenopathy after Intensive Frontline Chemoimmunotherapy Is Associated with Inferior Outcome Regardless of MRD Status in Advan…

2018

Abstract Introduction: In CLL, chemoimmunotherapies (CIT) and combinations with novel agents have proven to be highly effective with regard to eradication of minimal residual disease (MRD), while complete remissions (CR) are frequently not achieved due to residual lymphadenopathy. We have previously reported that minimal residual disease (MRD) negativity after CIT is a prognostic factor irrespective of the clinical response (Kovacs et al., JCO 2016). Because inferior outcome was observed in small subgroups of patients (pts) with residual lymphadenopathy, we analyzed the prognostic value of residual lymphadenopathy after CIT in comparison to MRD detection in a larger pt population. Methods: …

Thrombin generation - a potentially useful biomarker of thrombotic risk in Philadelphia-negative myeloproliferative neoplasms.

2017

The diagnosis of essential thrombocythemia and polycythemia vera is often made during a thrombotic event which can be serious. Philadelphia-negative chronic myeloproliferative neoplasia patients have an increased thrombotic risk. This is assessed using various scoring systems but these are far from ideal and individual risk. The currend trend to personalised medicine requires finding the most useful thrombotic risk biomarker in these patients. Routine tests for coagulation do not take account of both pro- and anti-coagulant factors which is why these tests are not useful in patients with Philadelphia-negative myeloproliferative neoplasms. Thrombin generation reflects more accurately the bal…

germline mutations in women with familial breast cancer and a relative with haematological malignancy

2009

Biallelic inactivation of the ATM gene causes ataxia-telangiectasia (A-T), a complex neurological disease associated with a high risk of leukaemias and lymphomas. Mothers of A-T children, obligate ATM heterozygote mutation carriers, have a breast cancer (BC) relative risk of about 3. The frequency of ATM carriers in BC women with a BC family history has been estimated to be 2.70%. To further our clinical understanding of familial BC and examine whether haematological malignancies are predictive of ATM germline mutation, we estimated the frequency of heterozygote mutation carriers in a series of 122 BC women with a family history of both BC and haematological malignancy and without BRCA1/2 m…

The Childhood Leukemia International Consortium

2013

Abstract Background : Acute leukemia is the most common cancer in children under 15 years of age; 80% are acute lymphoblastic leukemia (ALL) and 17% are acute myeloid leukemia (AML). Childhood leukemia shows further diversity based on cytogenetic and molecular characteristics, which may relate to distinct etiologies. Case–control studies conducted worldwide, particularly of ALL, have collected a wealth of data on potential risk factors and in some studies, biospecimens. There is growing evidence for the role of infectious/immunologic factors, fetal growth, and several environmental factors in the etiology of childhood ALL. The risk of childhood leukemia, like other complex diseases, is like…
