Therapy-related secondary malignancies after treatment for childhood malignancy: Cases from a single institution.

CONCLUSIONS: Our results revealed that the type of secondary malignancy depends on the number of years that have elapsed since treatment for primary malignancy was concluded. Meningioma, especially, develops many years after completion of primary malignancy treatment. It is therefore necessary to strive for early detection during long-term follow-up.

acute;-Vendrell E Abstract INTRODUCTION: Since the introduction of genetic and molecular criteria in the 2016 World Health Organization (WHO) classification of brain tumours, there has been a diagnostic reclassification between certain astrocytomas and oligodendro-gliomas with histological and genetic discordances, the prognosis of which is unknown. AIM: To analyse the implications of the diagnostic reclassification of brain gliomas according to the 2016 WHO criteria, especially depending on isocitrate dehydrogenase (IDH) mutation and 1p19q codeletion. PATIENTS AND METHODS: We conducted a retrospective s...

We report the case of a 47-year-old man who was diagnosed with severe right ventricular outflow tract (RVOT) stenosis due to a space-occupying lesion; the diagnosis was made using computed tomography. He underwent mass reduction, pulmonary valve replacement, and RVOT reconstruction with a bovine pericardial patch. The pathological diagnosis was undifferentiated pleomorphic sarcoma originating from the myocardium. As the mass resection was incomplete, he received heavy particle therapy. He did not want to receive adjuvant chemotherapy. Four months later, severe RVOT stenosis recurred because the residual mass had invaded th...

Proescholdt, T. PukropAbstractThe macro-metastasis/organ parenchyma interface (MMPI) was previously considered an inert anatomical border which sharply separates the affected organ parenchyma from the macro-metastatic tissue. Recently, infiltrative growth of macro-metastases from various primary tumors was described in the brain, liver and lung, with significant impact on survival. Strikingly, the MMPI patterns differed between entities, so...

In this direction, we have synthesized different mole ratio of PdO–TiO2 nanocomposites (1:1, 2:1 and 3:1 of Pd:Ti, size 5–11nm, 7–16 nm and 9–22 nm) through a simple single step sol&ndas...

Publication date: Available online 12 November 2019Source: Progress in NeurobiologyAuthor(s): Joseph H. Neale, Tatsuo YamamotoAbstractN-Acetylaspartylglutamate (NAAG) is the third most prevalent neurotransmitter in the mammalian nervous system, yet its therapeutic potential is only now being fully recognized. Drugs that inhibit the inactivation of NAAG by glutamate carboxypeptidase II (GCPII) increase its extracellular concentration and its activation of its receptor, mGluR3. These drugs warrant attention, as they are effective in animal models of several clinical disorders including stroke, traumatic brain injury and schi...

We describe a case of a 76-year-old Caucasian male who presented to the Emergency Department (ED) with weight loss, abdominal pain, and multiple episodes of vomiting and diarrhea. He underwent a laparotomy with an intraluminal mass seen in the cecum. Histology showed atypical intermediate- to large-sized cells involving the full thickness of the bowel wall with numerous mitotic figures and apoptotic bodies. The adjacent uninvolved mucosa demonstrated villous blunting, increased intraepithelial lymphocytes, crypt elongation, and lamina propria plasmacytosis, consistent with the celiac enteropathy. Rare large transformed cel...

A rapidly increasing number of reports on dysregulated long intergenic non-coding RNA (lincRNA) expression across numerous types of cancers indicates that aberrant lincRNA expression may be a major contributor to tumorigenesis. Marek’s disease (MD) is a T cell lymphoma of chickens induced by Marek’s disease virus (MDV). Although we have investigated the roles of lincRNAs in bursa tissue of MDV-infected chickens in previous studies, the molecular mechanisms of lincRNA functions in T cells remain poorly understood. In the present study, Linc-GALMD1 was identified from CD4+ T cells and MSB1 cells, and its expressi...

CONCLUSION: An exclusively extranodal manifestation of cHL in Waldeyer's ring is rare, whereas infiltration of extranodal tissue in the case of a primary manifestation of lymphoma in cervical nodes can occur more frequently and may often remain undiagnosed. Therefore, a specialized ENT consultation could be a reasonable complementary module in tumor staging to determine the correct tumor extent. PMID: 31712877 [PubMed - as supplied by publisher]

In this study, we loaded aldoxorubicin, an albumin-bound prodrug version of doxorubicin, onto NFP and tested the in vitro cytotoxicity in canine mammary carcinoma (CMT12, CMT25) and osteosarcoma (HMPOS, D-17, Abrams) cell lines. The half maximal inhibitory concentration (IC50) was determined with a luminescence-based cell viability assay. The IC50 for aldoxorubicin-loaded NFP was lower than free aldoxorubicin or doxorubicin in all cell lines, whereas non-drug loaded NFP had no cytotoxic effects. There were differences in IC50 between the osteosarcoma lines, with lower and higher IC50 for HMPOS and D-17 cells, respectively,...
