Risk behaviour and patient preferences for an improved non-melanoma skin cancer prevention modality for organ-transplanted patients: a European, multi-country, online patient community study.

Immunosuppressants used in organ transplant patients increase the risk of non-melanoma skin cancer. This study aimed to evaluate patient behaviours towards skin cancer prevention methods and to understand characteristics of a future prevention strategy based on patients' perspective. Carenity, a global online patient community, enabled the recruitment of 200 adult patients with solid organ transplants from four European countries: France, Italy, Spain and Germany.

Chromosomal rearrangements involving the NTRK1 gene in colorectal carcinoma.

Chromosomal rearrangements of the NTRK1 gene, which encodes the high affinity nerve growth factor receptor (tropomyosin related kinase, TRKA), have been observed in several epithelial cancers, such as colon cancer, papillary thyroid carcinoma or non small cell lung cancer. The various NTRK1 fusions described so far lead to constitutive activation of TRKA kinase activity and are oncogenic. We further investigated here the existence and the frequency of NTRK1 gene rearrangements in colorectal cancer.

F14512, a polyamine-vectorized anti-cancer drug, currently in clinical trials exhibits a marked preclinical anti-leukemic activity.

Chemotherapy remains mainly used for the treatment of acute myeloid leukemia (AML). However, in the past 3 decades limited progress has been achieved in improving the long-term disease-free survival. Therefore the development of more effective drugs for AML represents a high level of priority.

Optical imaging of disseminated leukemia models in mice with near-infrared probe conjugated to a monoclonal antibody.

Background: The assessment of anticancer agents to treat leukemia needs to have animal models closer to the human pathology such as implantation in immunodeficient mice of leukemic cells from patient samples. A sensitive and early detection of tumor cells in these orthotopic models is a prerequisite for monitoring engraftment of leukemic cells and their dissemination in mice. Therefore, we developed a fluorescent antibody based strategy to detect leukemic foci in mice bearing patient-derived leukemic cells using fluorescence reflectance imaging (FRI) to determine when to start treatments with novel antitumor agents.

Do AML patients with DNMT3A exon 23 mutations benefit from idarubicin as compared to daunorubicin? A single center experience.

Mutations in DNMT3A encoding DNA methyltransferase 3A were recently described in patients with acute myeloid leukemia. To assess their prognostic significance, we determined the mutational status of DNMT3A exon 23 in 288 patients with AML excluding acute promyelocytic leukemia, aged from 18 to 65 years and treated in Toulouse University Hospital. A mutation was detected in 39 patients (13.
