TL;DR: The participants concluded that nasal T/natural killer (NK) cell lymphoma is a distinct clinicopathologic entity highly associated with Epstein-Barr virus (EBV) and in situ hybridization for EBV an be very valuable in early diagnosis, especially if tissue is sparse.
Journal ArticleDOI
Papillary microcarcinoma of the thyroid—Prognostic significance of lymph node metastasis and multifocality
TL;DR: It is known that patients with papillary microcarcinoma of the thyroid gland have a very favorable prognosis, but the rising incidence of PMC among papillary thyroid carcinoma (PTC) necessitates the identification of prognostic factors and the formulation of treatment protocols.

TL;DR: To determine the frequency and importance of germline mutations in cancer-associated genes in OC, a study population of 1915 women with OC and available germline DNA was identified and mutations were compared with the National Heart, Lung, and Blood Institute GO Exome Sequencing Project (ESP) and the Exome Aggregation Consortium (ExAC).
Journal ArticleDOI
Primary non-Hodgkin's lymphoma of the nose and nasopharynx : Clinical features, tumor immunophenotype, and treatment outcome in 113 patients
TL;DR: Since the NK/T phenotype carries the worst prognosis, patients who present with NNP-NHL should have their tumors analyzed for CD56 expression, and the three immunophenotypes studied are shown to exhibit different clinical patterns.
Journal ArticleDOI
IgG4-related sclerosing disease: a critical appraisal of an evolving clinicopathologic entity.
Wah Cheuk,John K. Chan +1 more
TL;DR: An elevated serum titer of immunoglobulin G4 (IgG4), the least common of the 4 subclasses of IgG, is a surrogate marker for the recently characterized IgG4-related sclerosing disease, which affects predominantly middle-aged and elderly patients, with male predominance.
