Acute myeloid leukemia and myelodysplastic syndrome after adjuvant chemotherapy: A population ‐based study among older breast cancer patients

CONCLUSIONSAdjuvant chemotherapy is associated with a small but significant increase in the risk of AML and MDS, especially with regimens that include A. Longer follow‐up is needed to confirm that risk is not increased with the recently adopted TC regimen. Cancer 2017. © 2017 American Cancer Society.

Immunotherapy is a promising method of treatment for a number of cancers. Many of the curative results have been seen specifically in advanced-stage melanoma. Despite this, single-agent therapies are only successful in a small percentage of patients, and relapse is very common. As chemotherapy is becoming a thing of the past for treatment of melanoma, the combination of cellular therapies with immunotherapies appears to be on the rise in in-vivo models and in clinical trials. These forms of therapies include tumor-infiltrating lymphocytes, T-cell receptor, or chimeric antigen receptor-modified T cells, cytokines [interleuk...

In this study, we investigated TRAF3IP3 tumorigenic function. TRAF3IP3 protein was present in several cancer cell lines, with highest levels in melanoma. In addition, tumor microarray analysis on 23 primary melanoma and nine positive lymph nodes revealed that 70% of human primary melanoma and 66% of lymph node metastases were positive for TRAF3IP3. Importantly, TRAF3IP3 downregulation correlated with an 83% reduction of tumor growth in a subcutaneous xenograft mouse model (n=10, P=0.005). Immunohistochemistry analysis of the tumors revealed that TRAF3IP3-shRNA tumors had increased apoptosis (n=4, P

The aim of this study was to assess the prognostic importance of lymph node ratio (LNR) in stage III melanoma after complete lymph nodal dissections. From European Organization for Research and Treatment of Cancer randomized trials 18871, 18952, and 18991, 2358 patients had full information on positive and examined lymph nodes (LNs) and were included. Cox proportional hazards models stratified by trial were used to assess the prognostic impact of LNR adjusted for confounders on melanoma-specific survival. Optimal cutoff values for LNR were calculated for each LN dissection site (axillary, inguinal, and neck). LNR (≥ vs.

CONCLUSION Cognitive impairment can affect daily functioning, quality of life, and capacity to work in patients with cancer and those in remission. Consequently, cognitive assessment is now an important and necessary part of a comprehensive oncological care plan. Cancer-related cognitive impairment might be due to the direct effects of the cancer itself, nonspecific factors, or comorbid conditions that are independent of the disease and/or due to the adverse effects of the treatment or combination of treatments given for the disease. The prevalence and extent of cognitive impairment associated with cancer is recognized but...

ConclusionsThe burden of tAML/tMDS in Victoria is likely to be underestimated. Linkage between VCR and clinical registries is needed to provide more accurate insights.

We examined acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) events among 9679 women treated for breast cancer on four adjuvant Alliance for Clinical Trials in Oncology trials with>90  months of follow-up in order to better characterize the risk for AML/MDS in older patients receiving anthracyclines.MethodsWe used multivariable Cox regression to examine factors associated with AML/MDS, adjusting for age ( ≥65 vs.

Authors: Bertoli S, Sterin A, Tavitian S, Oberic L, Ysebaert L, Bouabdallah R, Vergez F, Sarry A, Bérard E, Huguet F, Laurent G, Prébet T, Vey N, Récher C Abstract Therapy-related acute myeloid leukemia (t-AML) is a heterogeneous entity most frequently related to breast cancer or lymphoproliferative diseases (LD). Population-based studies have reported an increased risk of t-AML after treatment of lymphomas. The aim of this study was to describe the characteristics and outcome of 80 consecutive cases of t-AML following treatment of LD. t-AML accounted for 2.3% of all AML cases, occurred 60 mont...

The therapy related myeloid neoplasms (t-MN) include the cases of therapy related myelodysplastic syndrome (t-MDS) and therapy related acute myeloid leukemia (t-AML) that occurs as a late complication of chemotherapy and/or radiotherapy administered to treat a previous neoplastic disease [1]. The alkylating agents and the topoisomerase II inhibitors are commonly implicated in the etiology of the disease, with a shorter latency period, 1 –5 years, for the topoisomerase II inhibitors. Most of patients with t-AML/t-MDS show an abnormal karyotype.

Abstract Risk of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) post-breast cancer treatment with adjuvant chemotherapy and granulocyte colony-stimulating factors (G-CSF) is not fully characterized. Our objective was to estimate MDS/AML risk associated with specific breast cancer treatments. We conducted a retrospective cohort study of women aged ≥66 years with stage I–III breast cancer between 2001 and 2009 using the Surveillance, Epidemiology, and End Results-Medicare database. Women were classified as receiving treatment with radiation, chemotherapy, and/or G-CSF. We used multivar...

Abstract Bone marrow cells and peripheral blood mononuclear cells obtained from both acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) patients contain upregulated levels of cell surface antigen CD33 compared with healthy controls. This difference enables the use of humanized anti-CD33 antibody conjugated to cytotoxic agents for CD33 targeted immunotherapy. However, the expression of the membrane-bound drug transporter P-glycoprotein (P-gp) has been shown to be critical for resistance against the cytotoxicity of a humanized anti-CD33 antibody conjugated to maytansine-derivative DM4. The aim of the pr...
