[Diagnostic value of the BRAF variant V595E in urine samples, smears and biopsies from canine transitional cell carcinoma].

Tierarztl Prax Ausg K Kleintiere Heimtiere 2018 Oct 12;46(5):289-295. Epub 2018 Dec 12.

Objective: Transitional cell carcinoma (TCC) is the most common malignant tumour of the canine urinary tract. Previously, the mutation of the BRAF gene V595E was identified in approximately 85 % of canine TCC cases by DNA sequencing of TCC tumour cells, both in frozen and paraffin-embedded tissue sections, as well as in urine. The objective of this study was to establish these methods in cytological smears and to investigate the prevalence of BRAF mutation V595E in canine TCC in our cohort of patients. Read More

A Female Patient with Xq28 Microduplication Presenting with Myotubular Myopathy, Confirmed with a Custom-Designed X-array.

Neuropediatrics 2018 Dec 12. Epub 2018 Dec 12.

Department of Medical Genetics, Medical School, National and Kapodistrian University of Athens, Athens, Greece.

X-linked myotubular myopathy (XLMTM) is a rare inherited neuromuscular disorder associated with mutations in the gene on the Xq28 region. We report a severely affected girl with XLMTM, caused by maternally inherited 661 kb Xq28 microduplication identified by chromosomal microarray analysis and confirmed also on DNA from muscle biopsy with a custom-designed X-chromosome-specific microarray. X-inactivation analysis revealed a skewed inactivation pattern on the proband's muscle biopsy. Read More

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

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

Magy Onkol 2018 Dec 25;62(4):222-229. Epub 2018 Sep 25.

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

1Department of Nuclear Medicine, Seoul National University Bundang Hospital, Seoul National University College of Medicine, 82, Gumi-ro 173 Beon-gil, Bundang-gu, Seongnam-si, Gyeonggi-do 13620 South Korea.

Planar scintigraphy using Tc-99m pertechnetate is useful for snapshot evaluation of hot thyroid nodules, which are pathologically follicular adenoma and seldom, if ever, malignant. The autonomy of the hot nodules has been demonstrated by the presence of thyroid-stimulating hormone-dependent extra-nodular thyroid tissue besides the hot nodules. Here, we present two cases of hot thyroid nodules in patients who underwent quantitative single-photon emission computed tomography/computed tomography (SPECT/CT). Read More

1Department of Histopathology, Sir Ganga Ram Hospital, Rajender Nagar, New Delhi, India.

Extragonadal germ cell tumors are most commonly encountered in the anterior mediastinum. The presence of sarcomatous malignancies in these tumors is a rare phenomenon that adversely impacts patient prognosis because of poor response to conventional cisplatin-based chemotherapy. Even more unusual is the presence of florid benign somatic proliferations that overshadow the germ cell component, often resulting in misdiagnosis and inappropriate management. Read More

Patients with anorectal malignant melanoma (ARMM) have a poor prognosis. Optimal surgical treatment is not defined. The aim of the study was to define the surgical treatment for ARMM, to compare the overall survival (OS) of abdomino-perineal resection (APR) and wide local excision (WLE) and to study various prognostic factors.

Solid Pseudopapillary Neoplasm of the Pancreas Clinicopathological Characteristics and Long-Term Outcome: a Single-Center Experience.

Indian J Surg Oncol 2018 Dec 18;9(4):483-487. Epub 2018 May 18.

Department of Radiology, GIPMER, New Delhi, India.

Solid pseudopapillary neoplasm is a rare tumor of the pancreas. These tumors are considered to have low malignant potential with good prognosis. Due to its rarity, details about clinical presentation and management of the disease are not very clear. Read More

Results of First-round of Surveillance in Individuals at High-risk of Pancreatic Cancer from the AISP (Italian Association for the Study of the Pancreas) Registry.

Am J Gastroenterol 2018 Dec 11. Epub 2018 Dec 11.

Pancreatic Surgery Unit, Humanitas Clinical and Research Center, Milano, Italy.

Introduction: Surveillance programs on high-risk individuals (HRIs) can detect pre-malignant lesions or early pancreatic cancer (PC). We report the results of the first screening round of the Italian multicenter program supported by the Italian Association for the study of the Pancreas (AISP).

Methods: The multicenter surveillance program included asymptomatic HRIs with familial (FPC) or genetic frailty (GS: BRCA1/2, p16/CDKN2A, STK11/LKB1or PRSS1, mutated genes) predisposition to PC. Read More

The proneural gene ASCL1 governs the transcriptional subgroup affiliation in glioblastoma stem cells by directly repressing the mesenchymal gene NDRG1.

Achaete-scute homolog 1 gene (ASCL1) is a gene classifier for the proneural (PN) transcriptional subgroup of glioblastoma (GBM) that has a relevant role in the neuronal-like differentiation of GBM cancer stem cells (CSCs) through the activation of a PN gene signature. Besides prototypical ASCL1 PN target genes, the molecular effectors mediating ASCL1 function in regulating GBM differentiation and, most relevantly, subgroup specification are currently unknown. Here we report that ASCL1 not only promotes the acquisition of a PN phenotype in CSCs by inducing a glial-to-neuronal lineage switch but also concomitantly represses mesenchymal (MES) features by directly downregulating the expression of N-Myc downstream-regulated gene 1 (NDRG1), which we propose as a novel gene classifier of MES GBMs. Read More

ALDH1A3 induces mesenchymal differentiation and serves as a predictor for survival in glioblastoma.

Cell Death Dis 2018 Dec 11;9(12):1190. Epub 2018 Dec 11.

Chinese Glioma Genome Atlas Network(CGGA) and Asian Glioma Genome Atlas Network (AGGA), Beijing, China.

As aldehyde dehydrogenase (ALDH) is a novel stem cell marker, increasing studies have confirmed that high ALDH activity promotes tumorigenesis and progression in cancers. Some preliminary studies have found that ALDH1A3 may play an important role in glioma malignant progression, but so far there was no conclusive conclusion. The purpose of our study was to elucidate the mechanisms by which ALDH1A3 regulated in glioma and to provide practical tools for clinical application. Read More
