Prognostic value of NOTCH1 and OCT4 in gastric carcinoma.

Background: NOTCH1 pathway activation has been recently described to be a key player in gastric carcinogenesis, enhance the survival and proliferation of cancer stem cells (CSCs) and mediate chemoresistance in several malignancies.

Aim: This study investigated the correlation between NOTCH1 and CSC marker OCT4 (octamer binding transcription factor-4) expression and the clinicopathological properties, survival and treatment outcome in patients with gastric carcinoma (GC) receiving adjuvant chemotherapy. Materials and.

Fatty acid synthase, Her2/neu, and E2F1 as prognostic markers of progression in non-muscle invasive bladder cancer.

Non-muscle-invasive bladder cancer (NMIBC) is a heterogeneous disease which has an unpredictable risk of progression to muscle-invasive bladder cancer (MIBC). The selection of patients who may benefit from early radical intervention is a challenge. To define the useful prognostic markers for progression, we analyzed the immunohistochemical expression of fatty acid synthase (FASN), Her2/neu, and E2F1 in 60 cases of NMIBC who underwent TURBT and adjuvant intravesical bacillus-Calmette-Guérin (BCG).

The clinicopathological significance of CD133 and Sox2 in astrocytic glioma.

Background: The treatment strategies of astrocytoma have not changed considerably due to the restricted appreciation of its biology.

Objectives: This study aimed to evaluate the expression of the stem cell-related proteins (CD133 and Sox2) and their prognostic value in astrocytic glioma.

Methods: The immunohistochemical expression of CD133 and Sox2 in 40 patients with an astrocytic glioma of different grades was studied.

Prognostic impact of Apaf-1, Cyclin D1, and AQP-5 in serous ovarian carcinoma treated with the first-line chemotherapy.

Unlabelled: Chemoresistance is the major obstacle to effective treatment in patients with serous ovarian carcinoma (SOC), which frequently related to the failure of chemotherapeutic agents to induce apoptosis. In this study, the immunohistochemical expression of Apaf-1, Cyclin D1, and Aquaporin-5 (AQP-5) was studied in 50 paraffin blocks of SOC. Data on overall survival (OS), disease-free survival (DFS) and response to the first-line chemotherapy were collected and then statistically analyzed.
