Carcinoma del conducto salival: estudio clínico/patológico e inmunohistoquímico de 5 casos

El carcinoma del conducto salival es un tumor epitelial maligno agresivo, que involucra principalmente a la glándula parótida, con características histológicas semejantes al carcinoma ductal de glándula mamaria. El propósito de este trabajo fue presentar los resultados clínico-patológicos de cinc...

Comparison of microRNA profiles between benign and malignant salivary gland tumors in tissue, blood and saliva samples: a prospective, case-control study

Abstract Introduction: Salivary gland tumors (SGTs) are rare head and neck malignancies consisting of a spectrum of tumors with different biological behaviors. Objective: In this study we aimed to find out differential expression of microRNA profiles between benign and malignant SGTs. Methods: We inve...

DNA Aneuploidy in Malignant Salivary Gland Neoplasms is Independent of USP44 Protein Expression

Braz. dent. j; 28 (2), 2017
Chromosomal instability, leading to aneuploidy, is one of the hallmarks of human cancers. USP44 (ubiquitin specific peptidase 44) is an important molecule that plays a regulatory role in the mitotic checkpoint and USP44 loss causes chromosome mis-segregation, aneuploidy and tumorigenesis in vivo. In this...

Carcinoma ex-pleomorphic adenoma derived from recurrent pleomorphic adenoma shows important difference by array CGH compared to recurrent pleomorphic adenoma without malignant transformation

Abstract Introduction: A key step of cancer development is the progressive accumulation of genomic changes resulting in disruption of several biological mechanisms. Carcinoma ex-pleomorphic adenoma (CXPA) is an aggressive neoplasm that arises from a pleomorphic adenoma. CXPA derived from a recurrent PA ...

Avaliação da via do c-kit no adenoma pleomórfico e carcinoma adenoide cístico das glândulas salivares: estudo da expressão das proteínas da via, das mutações e da regulação pós-transcricional do gene kit

Introdução: As neoplasias das glândulas salivares têm amplo espectro histológico resultante da múltipla diferenciação celular tumoral. O adenoma pleomórfico (AP) e o carcinoma adenoide cístico (CAC) são as mais comuns neoplasias benignas e malignas provenientes do ducto intercalado, respectiva...
