The prognostic significance of the heterologous component in uterine carcinosarcomas.

Objective: Uterine carcinosarcomas are aggressive, rare biphasic tumors with malignant epithelial and malignant sarcomatous components. The prognostic significance of the presence of extrauterine sarcoma (heterologous component) is controversial. Therefore, the aim of this study was to investigate the effect of heterologous components in uterine carcinosarcomas on disease-free survival, overall survival, and other prognostic factors.

Tissue Expression of Neutrophil Gelatinase-Associated Lipocalin and Kidney Injury Molecule-1 in Breast Cancers.

Objective: Breast cancer is the most common cancer among women worldwide. Neutrophil gelatinase-associated lipocalin (NGAL) has important roles in immunity, cell proliferation, and carcinogenesis. Kidney injury molecule-1 (KIM-1) is a transmembrane glycoprotein also known as hepatitis A virus cellular receptor 1 and T-cell immunoglobulin and mucin, has restricted expression in immune cells and healthy epithelial cells, but it is up-regulated in several human cancers.

Evaluation of the Prognostic Significance of Cereblon Protein Expression in Multiple Myeloma.

Background: Considerable progress has been made in the treatment of multiple myeloma (MM) patients with the development of various new agents that increased survival rates over the past fifteen years. Cereblon (CRBN) plays an important role in mediating the antitumor effects of immunomodulatory drugs (IMiDs) among these new agents. The aim of our study is to investigate immunohistochemically (IHC) cereblon protein expression status in MM.

Analysis of vanishing endometrial cancer by pathological types.

Purpose: We asked why endometrial cancer sometimes vanishes.

Methods: A total of 454 patients diagnosed with endometrioid-type endometrial cancer (EC) (via endometrial sampling) and treated in our clinic over the past 5 years were enrolled. The patients were divided into two groups: vanishing and residual, depending on whether a tumor was detected in the postoperative hysterectomy specimen.

Microsurgical endoscopy-assisted presigmoid retrolabyrinthine approach with mastoid bone drilling: an anatomical laboratory investigation.

Purpose: This study aims to evaluate the applicability of the endoscopy-assisted presigmoid retrolabyrinthine approach, advantages, disadvantages, and the applicability of surgery with pre-op radiological parameters; identify important landmarks; and to reveal their relationships with important structures in the surgical field with objective data. Also, we aim to improve the surgical technique for increasing reachable anatomic structure.

Methods: Mastoid drilling and endoscopy-assisted presigmoid retrolabyrinthine approach were performed and endoscopic instruments were used to obtain the three-dimensional pictures.
