Mutation analysis of therapy-related myeloid neoplasms

Publication date: April 2018 Source:Cancer Genetics, Volumes 222–223 Author(s): Takahiro Nishiyama, Yuichi Ishikawa, Naomi Kawashima, Akimi Akashi, Yoshiya Adachi, Hikaru Hattori, Yoko Ushijima, Hitoshi Kiyoi We analyzed the genetic mutation status of 13 patients with therapy-related myeloid neoplasms (t-MN). Consistent with previous reports, t-MN cells preferentially acquired mutations in TP53 and epigenetic modifying genes, instead of mutations in tyrosine kinase and spliceosome genes. Furthermore, we compared the mutation status of three t-MN cells with each of the initial lymphoid malignant cells, and identified common mutations among t-MN and the initial malignant cells in two patients. In a patient who developed chronic myelomonocytic leukemia (CMML) after follicular lymphoma (FL), TET2 mutation was identified in both CMML and FL cells. Notably, the TET2 mutation was also identified in peripheral blood cells in the disease-free period with the same allelic frequency as CMML and FL cells, but not in a germ-line control, indicating that the TET2 mutation occurred somatically in the initiating clone for both malignant cells. On the other hand, a germ-line MYB mutation was identified in a patient who developed myelodysplastic syndromes (MDS) after FL. These results suggest that germ-line deposition and clonal hematopoiesis are closely associated with t-MN susceptibility; however, further analysis is necessary to clarify the mechanism required to provide the initiatin...

Conclusions: Sepsis is associated with increased or decreased risks for a small group of cancers. Factors that may explain these associations include etiologic effects of bacterial infections, inflammation, or use of antibiotics. Other associations may reflect the presence of precursor conditions (e.g., cirrhosis, colorectal polyps) or patterns in ascertainment of cancer and screening.

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...

The majority of blood cancers occur in the elderly. This fact conspires with an aging population in many countries to make rigorous assessment for frailty increasingly important for hematologic oncologists. In this review, we first define frailty and its relevance for patients with hematologic malignancy. Next, we review current data regarding the effect of domains of frailty on outcomes for blood cancers including myelodysplastic syndromes, acute leukemia, non-Hodgkin lymphomas such as chronic lymphocytic leukemia, and multiple myeloma. Finally, after presenting assessment and treatment options for the practicing hematolo...

Conclusion Bendamustine is an effective therapy with limited long-term sequelae in patients with lymphoid malignancies. Micro-Abstract Bendamustine is an effective treatment for lymphoid malignancies and its role continues to expand. To determine the long-term sequelae associated with bendamustine, 194 patients treated with bendamustine (most commonly with rituximab) were retrospectively reviewed. The rate of secondary malignancies was minimal and no therapy-related myelodysplastic syndrome or acute myelogenous leukemia were reported. No deaths from infection were attributable to bendamustine.

Are the myeloid malignancies leading the way, based on our ability to easily obtain tumor tissue and success in CML, or are they following, given the use of multi-gene panels to treat upfront advanced lung cancer and the remarkable outcomes using check point inhibitors to treat formerly intractable solid tumors? Past achievements in the leukemias have been impressive but incomplete. In chronic phase CML we have essentially curative treatments; in myeloproliferative neoplasms we know the mutations but possess only partially effective therapies; and in myelodysplastic syndrome many mutations have been described but effective...

Abstract BackgroundSecond hematologic cancers in patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL) are well documented and include Hodgkin lymphoma, therapy‐related acute myeloid leukemia/myelodysplastic syndromes, and transformation to diffuse large B‐cell lymphoma. Although cutaneous T‐cell lymphoma (CTCL) has been reported in patients with CLL, the incidence and comparison to expected rates are unknown. We evaluated the incidence of CTCL among patients with CLL or other non‐Hodgkin lymphoma (NHL) subtypes using data from the Surveillance, Epidemiology, and End Results (SEER) Program. Me...

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...

Summary Cancer‐related cognitive impairment (CRCI) is an important clinical problem for cancer patients and survivors. In this review, we summarize studies investigating the occurrence of impaired cognition in patients with haematological malignancies. Most published studies focus on survivors of childhood acute lymphoblastic leukaemia and primary central nervous system lymphoma. We also discuss studies conducted in acute myeloid leukaemia, myelodysplastic syndromes, chronic myeloid leukaemia, Hodgkin lymphoma (HL), non‐HL and chronic lymphocytic leukaemia. Although research in this area is still emerging, it appears t...
