Cancer stem cells in relation to treatment.

Jpn J Clin Oncol 2018 Dec 12. Epub 2018 Dec 12.

Department of Gastroenterological Surgery, Osaka University Graduate School of Medicine, Osaka, Japan.

The classical cancer therapies, including chemotherapy and radiation therapy, can initially show good results and tumor shrinkage; however, for most cancer patients disease recurrence is a common event. This tumor regrowth following therapy is now thought to depend on a small population of cancer stem cells (CSCs), which, similar to other stem cells, have the capacity for self-renewal and multipotent differentiation. Cancer stem cells have been identified based on cell surface protein expression in many tumor types, and for all diseases studied, this specific cell population is required for serial transplantation in animal models.

TNM classification of malignant tumors (Breast Cancer Study Group).

Jpn J Clin Oncol 2018 Dec 12. Epub 2018 Dec 12.

Department of Breast Oncology, Aichi Cancer Center Hospital, Nagoya, Japan.

The eighth editions of the primary tumor, lymph node and metastasis classifications for breast cancer issued by the American Joint Commission of Cancer and the Union for International Cancer Control were revised in 2017. The major change made by the American Joint Commission of Cancer is to incorporate biological factors such as estrogen and progesterone receptor, human epidermal growth factor receptor 2, histological grade and multigene prognostic assays, into the staging system. Tumor biomarkers and low recurrence scores confirmed by multigene prognostic assays change the staging. Read More

Thyroid Sequelae of Pediatric Cancer Therapy.

Horm Res Paediatr 2018 Dec 12:1-14. Epub 2018 Dec 12.

The hypothalamic-pituitary-thyroid axis is a common site of unintended, acquired disease either during or after the treatment of cancer. Children treated with external radiation therapy are at the highest risk for developing a thyroid-related late effect, but thyroid dysfunction and second primary thyroid neoplasms can also occur after treatment with radiopharmaceutical agents such as 131I-metaiodobenzylguanidine. Increasingly recognized is the development of early thyroid dysfunction as an off-target consequence of the more novel cancer therapeutics such as the tyrosine kinase inhibitors and immune checkpoint inhibitors.

KLF4, A Gene Regulating Prostate Stem Cell Homeostasis, Is a Barrier to Malignant Progression and Predictor of Good Prognosis in Prostate Cancer.

Cell Rep 2018 Dec;25(11):3006-3020.e7

Department of Cell Biology, NYU School of Medicine, New York, NY 10016, USA; Department of Urology, NYU School of Medicine, New York, NY 10016, USA. Electronic address:

There is a considerable need to identify those individuals with prostate cancer who have indolent disease. We propose that genes that control adult stem cell homeostasis in organs with slow turnover, such as the prostate, control cancer fate. One such gene, KLF4, overexpressed in murine prostate stem cells, regulates their homeostasis, blocks malignant transformation, and controls the self-renewal of tumor-initiating cells. Read More

PARP Inhibition Elicits STING-Dependent Antitumor Immunity in Brca1-Deficient Ovarian Cancer.

Cell Rep 2018 Dec;25(11):2972-2980.e5

Department of Cancer Biology, Dana-Farber Cancer Institute, Boston, MA 02215, USA; Department of Biological Chemistry and Molecular Pharmacology, Harvard Medical School, Boston, MA 02115, USA; Broad Institute of Harvard and MIT, Cambridge, MA 02142, USA. Electronic address:

PARP inhibitors have shown promising clinical activities for patients with BRCA mutations and are changing the landscape of ovarian cancer treatment. However, the therapeutic mechanisms of action for PARP inhibition in the interaction of tumors with the tumor microenvironment and the host immune system remain unclear. We find that PARP inhibition by olaparib triggers robust local and systemic antitumor immunity involving both adaptive and innate immune responses through a STING-dependent antitumor immune response in mice bearing Brca1-deficient ovarian tumors.

Endoscopic technology is widely used in rhinology and anterior skull base surgery, but it has been less quickly incorporated into otologic practice. The design of the instrumentation forces surgeons to work one-handed and limits depth perception. Nevertheless, endoscopy also offers wide fields of view and access to spaces that are typically difficult to visualize. Read More

II. Sz. Gyermekgyógyászati Klinika, Semmelweis Egyetem, Budapest, Hungary.

Malignant tumors found in children are different from the ones that occur in adults. Compared to the malignancies in adults, the histological entities in pediatric patients are different and survival rates are higher among the children. Though pediatric soft tissue sarcomas are less common than leukemia and central nervous system malignancies, recognition of them is necessary to start the therapy as soon as possible. Read More

Am J Surg Pathol 2018 Dec 11. Epub 2018 Dec 11.

INSERM1052, CNRS 5286, Lyon-Sud Charles Mérieux Lyon-1 Faculty, Claude Bernard University.

Gray-zone lymphoma (GZL) with features intermediate between classic Hodgkin lymphoma (cHL) and large B-cell lymphoma (LBCL) was introduced as a provisional entity into the World Health Organization classification in 2008.

Active Targeting of Cancer Cells by Nanobody Decorated Polypeptide Micelle with Bioorthogonally Conjugated Drug.

Nano Lett 2018 Dec 12. Epub 2018 Dec 12.

Polypeptides are exceptionally promising carriers for chemotherapeutics: they have minimal toxicity, can be recombinantly synthesized with precise control over molecular weight, and enhance drug pharmacokinetics as self-assembled nanoparticles. Polypeptide-based systems also provide the ability to achieve active targeting with genetically encoded targeting ligands. While passive targeting promotes accumulation of nanocarriers in solid tumors, active targeting provides an additional layer of tunable control and widens the therapeutic window. Read More

Hum Pathol 2018 Dec 7;82:39-45. Epub 2018 Jul 7.

Department of Pathology, Stanford University School of Medicine, Stanford, CA 94305, USA. Electronic address:

Undifferentiated malignancies (UMs) encompass a diverse set of aggressive tumors that pose not only a diagnostic challenge but also a challenge for clinical management. Most tumors in this category are currently treated empirically with nonspecific chemotherapeutic agents that yield extremely poor clinical response. Given that UMs are inherently genetically unstable neoplasms with the potential for immune dysregulation and increased neoantigen production, they are likely to be particularly amenable to immune checkpoint inhibitors, which target programmed cell death protein 1 (PD-1) or its ligands, PD-L1 and PD-L2, to promote T-cell antitumor activity.

Introduction: iGlarLixi is a titratable, fixed-ratio combination of insulin glargine (100 units/mL) and lixisenatide (33 μg/mL). This review evaluates the overall safety and adverse event (AE) profile of iGlarLixi in patients with type 2 diabetes.

Methods: We collated patient-level data from the phase 2 LixiLan proof-of-concept trial and the phase 3 LixiLan-L (insulin-experienced patients) and LixiLan-O (insulin-naïve patients) trials to evaluate AEs associated with iGlarLixi. Read More

Pathol Oncol Res 2018 Dec 11. Epub 2018 Dec 11.

Department of Clinical Biochemistry, Sher-I-Kashmir Institute of Medical Sciences, Soura, Srinagar, Kashmir, 190011, India.

Sonic hedgehog (SHH) is a secreted protein which functions in autocrine or paracrine fashion on target cells to activate hedgehog (HH) signalling cascade responsible for growth and proliferation. This study is an attempt to understand the expression dynamics of SHH protein in colon, rectal and pancreatic cancers. Protein expression of SHH was studied by Western Blotting in the histologically confirmed colon, rectum and pancreatic cancer tissue samples along with their adjacent normal tissues. Read More

Liquid-Biopsy-Based Identification of EGFR T790M Mutation-Mediated Resistance to Afatinib Treatment in Patients with Advanced EGFR Mutation-Positive NSCLC, and Subsequent Response to Osimertinib.

Background: Acquired epidermal growth factor receptor (EGFR) T790M mutation is the primary resistance mechanism to first-generation EGFR tyrosine kinase inhibitors (TKIs) used in advanced, EGFR mutation-positive non-small-cell lung cancer (NSCLC). Available data, predominantly in Asian patients, suggest that this mutation is also the major cause of resistance to the irreversible ErbB family blocker, afatinib. For EGFR T790M-positive patients who progress on EGFR TKI therapy, osimertinib is an effective treatment option. Read More
