Are micro-RNA 21 and 143 indicative as prognostic biomarkers in dedifferentiated endometrial adenocarcinoma?

Aim: Dedifferentiated endometrial adenocarcinoma (DEAC) is a rare, aggressive subtype, accounting for 2% of all endometrial cancers. Poor survival in DEAC prompts the need for effective treatment modalities through better prognostic classification. MicroRNAs (miRNA) have essential roles in tumor angiogenesis, which might enable their use as novel biomarkers.

The association of polypoid growth pattern with lymph node involvement in endometrioid type endometrial adenocarcinoma.

Background: Tumor size is an independent predictor of lymph node metastasis and survival in the endometrioid type endometrial adenocarcinoma (EC). However, some of the ECs tend to grow towards the cavity in the polypoid pattern, which can reach very large sizes. In this study, we aimed to analyze the association of growing in the polypoid pattern of the tumor with the proportion of lymph node metastasis and extrauterine tumor spread.

Is microcystic, elongated, and fragmented pattern of myometrial invasion in endometrioid endometrial carcinoma associated with survival?

Background: Microcystic, elongated, and fragmented (MELF) pattern is one of the myometrial invasion patterns in endometrioid endometrial carcinoma (EEC), and it has been associated with poor prognostic parameters, especially lymphovascular space invasion (LVSI) and lymph node metastasis (LNM). This study aims to represent the frequency of MELF pattern in EEC and the relationship between MELF pattern with clinicopathological parameters, overall survival (OS), and disease-free survival (DFS).

Methods: In this retrospective cohort study, we examined 233 patients with EEC diagnoses with the result of a total hysterectomy and bilateral salpingo-oophorectomy between 2009 and 2014.

The impact of uterine adenomyosis on the histopathological risk factors and survival in patients with endometrial adenocarcinoma.

A retrospective cohort study was performed on patients diagnosed with endometrial adenocarcinoma (EC) during a 9-year period to investigate the impact of co-existing adenomyosis on patients with EC.

Prognostic significance of androgen receptor expression in HER2-positive and triple-negative breast cancer.

Triple-negative breast cancer (TNBC) and HER2-positive breast cancer are more aggressive than other subtypes of breast cancer. Due to the limited number of treatment alternatives and the absence of target receptors in TNBC, and because of progression in the HER2-positive group despite targeted treatments, new treatment targets and therapeutic combinations are required. In this context, the present study aims to evaluate the prognostic importance of immunohistochemical androgen receptor (AR) expression in HER2-positive breast cancer and TNBC subtypes.

An efficient biomarker panel for diagnosis of breast cancer using surface-enhanced laser desorption ionization time-of-flight mass spectrometry.

Breast cancer (BC) is the most frequently diagnosed cancer that affects women worldwide. Early detection of BC is important to improve survival rates and decrease mortality. The aim of the present study was to investigate serum biomarkers using surface-enhanced laser desorption ionization time-of-flight mass spectrometry (SELDI-TOF-MS) to distinguish patients with BC from the healthy population and patients with benign breast diseases (BBDs).

The prognostic significance of cyclin D1 expression in patients with triple-negative breast cancer.

Purpose: Breast cancer (BC) is the most common cancer and the second leading cause of cancer death among women. While receptor-targeted therapies are used for other subtypes due to the presence of such receptors, studies are still continuing on receptor expression in order to identify new therapeutic targets as the triple-negative breast cancer (TNBC) lacks a target receptor and its prognosis is worse than the other subtypes. Cyclin D1 (CycD1) is a cell cycle regulator protein.
