Human haematological and epithelial tumor-derived cell lines express distinct patterns of onco-microRNAs.

In this study, we analysed differences in miRNA expression profile between haematological and epithelial tumor-derived cell lines and explored their role in definying different cancer cells phenotypes. Cancer Focus microRNA PCR Panel was used to analyze eighty-four oncomiRNAs in two human haematological (K562 and HL-60) and in two epithelial (H460 and MCF-7) cancer cell lines. Bioinformatic tools were used to identify miRNA-specific signatures and to discover potentially deregulated pathways. Our analysis led to the identification of i) a large repertoire of miRNAs commonly expressed in the four cell lines, including two equally highly expressed (UPmiRs) and four equally low expressed (DNmiRs); ii) two miRNAs signatures, one associated with the haematological and one with the epithelial cell lines; iii) miRNA signatures specific for the acute or for the chronic myeloid leukemic cells; iv) miRNA signatures specific for the lung or for the breast carcinoma cells. As a whole, these results strengthen the significance of miRNAs profiling in human cancer subtyping, providing the ground for the identification of novel potential biomarkers for specific cancer cell phenotypes.

Authors: Matanes E, Abitbol J, Kessous R, Kogan L, Octeau D, Lau S, Salvador S, Gotlieb WH Abstract OBJECTIVE: In view of the recent controversy concerning the use of minimally invasive radical hysterectomy as primary treatment for early stage cervical cancer, this study compared the survival and perioperative outcomes in a cohort of patients who underwent radical hysterectomy either by laparotomy or by robotics. METHODS: This retrospective study compared all consecutive patients with early stage cervical cancer since the beginning of the Division of Gynecologic Oncology at the Jewish General Hospital in 2003, ...

CONCLUSION: Observational studies suggest some degree of association between serum hormones measured in pregnancy and a woman's future risk of breast and ovarian cancer. More data are needed to determine sufficiently whether certain blood hormone levels measured in pregnancy are predictive of future cancer risk. PMID: 30528445 [PubMed - as supplied by publisher]

Authors: Lee S, Cohen DJ Abstract INTRODUCTION: Esophageal cancer is a heterogeneous cancer comprised of differing cells of origin, molecular changes, and immune microenvironments. To date, most advances have been made in chemotherapy regimens where a one-size-fits-all approach is used. As a result, there remains a lack of tailored treatment options for such a heterogeneous cancer. This paper highlights the current standard of care treatment options as well as active areas of clinical research. Areas covered: The authors review the key trials that have led to current standard of care treatment including pivotal che...

Authors: Penna F, Costelli P Abstract INTRODUCTION: Cachexia is a frequent feature of chronic diseases. This syndrome includes loss of body weight, depletion of skeletal muscle mass and altered metabolic homeostasis. Acceleration of protein and energy metabolism, impaired myogenesis and systemic inflammation contribute to cachexia. Its occurrence impinges on treatment tolerance and on the quality of life of the patient, however, no effective therapy is available yet. Areas covered: This review focuses on the use of histone deacetylase inhibitors as pharmacological tools to prevent or delay cachexia, with reference ...

We present a case of 75-year-old male diagnosed in 2008 with a tumor located in the right naso-orbital region. The patient underwent surgical treatment, the histopathology being consistent with BCC. He presented recurrences of the tumor in 2009 and 2010 that were excised at approximately 9 and 16 months, respectively, from the first intervention. In 2010, the surgical procedure was radical, with removal of the tumor and the entire right superior eyelid. This approach proved to have negative side effects over the right eye in time. Therefore, after two months, a complete exenteration of the right orbit was necessary. The tu...

Background: CLL is the most common leukemia diagnosis in adults and its treatment has undergone significant change from chemotherapy, to immunotherapy and now targeted kinase inhibitors, leading to improved overall survival (OS). With improving survivorship, SPMs can occur but an in-depth analysis of risks and trends of SPMs in CLL survivors is lacking. We performed a population-based analysis to evaluate this.Methods: Patients in the Surveillance, Epidemiology and End Results (SEER) database diagnosed with CLL between 1973-2015 were included. Due to variation in management techniques over time, the cohort was divided in f...

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...
