Journal ArticleDOI
Gastric cancer: epidemiology, prevention, classification, and treatment.
Robert Sitarz,Robert Sitarz,Małgorzata Skierucha,Jerzy Mielko,G. Johan A. Offerhaus,Ryszard Maciejewski,Wojciech Polkowski +6 more
TL;DR: A trend of steady decline in gastric cancer incidence rates is the effect of the increased standards of hygiene, conscious nutrition, and Helicobacter pylori eradication, which together constitute primary prevention.
Journal ArticleDOI
Gastric Cancer: Epidemiology, Risk Factors, Classification, Genomic Characteristics and Treatment Strategies.
TL;DR: Early-onset gastric cancer is a good model to study genetic alterations related to the carcinogenesis process, as young patients are less exposed to environmental carcinogens.
Journal ArticleDOI

Journal ArticleDOI
Diagnostic and prognostic significance of miRNA signatures in tissues and plasma of endometrioid endometrial carcinoma patients.
Anna Torres,Kamil Torres,Anna Pesci,Marcello Ceccaroni,Tomasz Paszkowski,Paola Cassandrini,Giuseppe Zamboni,Ryszard Maciejewski +7 more
TL;DR: It is concluded that miRNA signatures hold a great promise to become noninvasive biomarkers for early EEC detection and prognosis.
Journal ArticleDOI
Deregulation of miR-100, miR-99a and miR-199b in tissues and plasma coexists with increased expression of mTOR kinase in endometrioid endometrial carcinoma
Anna Torres,Kamil Torres,Anna Pesci,Marcello Ceccaroni,Tomasz Paszkowski,Paola Cassandrini,Giuseppe Zamboni,Ryszard Maciejewski +7 more
TL;DR: It is implicate that miRNA signatures can be considered promising biomarkers for early detection and prognosis of endometrioid endometrial carcinoma and miR-100 was an independent prognostic marker of overall survival.
