The Prognostic Significance of CD47, CD68, and CD163 Expression Levels and Their Relationship with MLR and MAR in Locally Advanced and Oligometastatic Nasopharyngeal Carcinoma.

Background: This study aimed to assess the prognostic and predictive implications of CD47, CD68, and CD163, biomarkers of tumor-associated macrophages (TAMs), on the treatment efficacy and clinical outcomes of nasopharyngeal carcinoma (NPC). Additionally, the prognostic value of TAM-related indices, such as the monocyte-to-lymphocyte ratio (MLR) and monocyte-to-albumin ratio (MAR), was evaluated.

Methods: A retrospective cohort of 54 patients with locally advanced or oligometastatic NPC treated with concurrent chemoradiotherapy (CCRT), with or without induction chemotherapy, was analyzed.

Stanniocalcin-2 expression in glioblastoma - A novel prognostic biomarker: An observational study.

The objective of this study was to assess the prognostic relevance of Stanniocalcin-2 (STC2) expression, as determined via immunohistochemistry in tumor tissue, in a cohort of 83 patients diagnosed with glioblastoma who underwent maximal safe surgical resection followed by radiotherapy concurrent with adjuvant temozolomide. STC2 expression levels were categorized using a 3-tiered semiquantitative system: negative expression (level 0-), low expression (level 1+), and high expression (levels 2 + and 3+). Patients were categorized into 2 distinct groups according to their STC2 expression levels: negative STC2 (-/+) and positive STC2 (++/+++).

The frequency and prognostic role of P53 and P16 immunoexpression in primary ovarian mucinous tumors.

Background: Primary ovarian mucinous tumors are uncommon. Factors leading to invasive progression and metastatic disease have not been fully delineated yet. The aim of this study is to determine the rates of p53 and p16 immunoexpressions in primary ovarian mucinous tumors, to investigate their relationship with clinicopathologic factors and their impact on prognosis and survival.

FOXA1 is associated with high tumor grade, myometrial invasion and lymph node invasion in endometrial endometrioid carcinoma.

Objectives: FOXA1 expression has been demonstrated in several hormone-dependent cancers. However, data are limited concerning the role of FOXA1 in endometrial cancers. The present study aimed to investigate FOXA1 expression via the microarray technique in benign hyperplasia, endometrial intraepithelial neoplasia, and endometrial endometrioid carcinoma.

The extent of cyclin D1 expression in endometrial pathologies and relevance of cyclin D1 with the clinicopathological features of endometrioid endometrial carcinoma.

Background: Cyclin D1, a member of the cyclin protein family, is instrumental in the cell cycle due to its influence on the progression from G1 to the S phase. Its overexpression causes reduced doubling time and is also associated with clonogenic growth. The purpose of the present study was to assess cyclin D1 expression in patients with simple hyperplasia (SH), endometrial intraepithelial neoplasia (EIN) and endometrioid endometrial carcinoma, and to evaluate whether there was an association between cyclin D1 expression and the clinicopathological features of endometrioid endometrial carcinoma.

Two Uncommon Sites of Metastasis: Breast and Hypophysis Metastases of Head and Neck Adenoid Cystic Carcinoma Detected by FDG PET/CT.

Adenoid cystic carcinoma (ACC) is a rare epithelial malignancy arising from secretory glands, particularly the salivary glands. It tends to invade nerves and has a high potential for distant hematogenous metastasis, especially to the lungs, bone, liver and brain. The breast and hypophysis are not common sites of ACC metastatic disease.

The value of FDG PET/CT parameters, hematological parameters and tumor markers in predicting KRAS oncogene mutation in colorectal cancer.

Objective: In this study we investigated the predictive value of maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), total lesion glycolysis (TLG), neutrophils/lymphocytes ratio (NLR), platelets/lymphocytes ratio (PLR), carcinoembryonic antigen (CEA) and carbohydrate antigen (CA 19-9) in the prediction of KRAS gene mutation which plays an important role in the choice of treatment in colorectal cancer patients.

Subjects And Methods: A total of 55 cases with untreated colorectal cancer who had undergone both PET/CT examinations for initial staging and also mutation analysis of KRAS oncogene were studied. Fluorine-18-FDG PET/CT parameters (SUVmax, MTV, TLG), hematological parameters (NLR, PLR), and tumor markers (CEA, CA 19-9) were recorded and the relationship between these parameters and KRAS oncogene mutation was evaluated using receiver operating characteristics (ROC) analysis and multiple logistic regression analysis.

First Aid Knowledge of University Students in Poisoning Cases.

Objectives: Poisoning is a crucial public health problem which needs serious approach and response to treatment. In case of poisoning, proper first aid is lifesaving and application should be applied in every condition. This research was conducted in order to evaluate first aid knowledge of university students for poisoning.

TTF-1 may not be a reliable marker for differentiating metastasis from brain tumors.

Objective: TTF-1 is widely used as an immunohistochemical marker of lung and thyroid tumors. However, TTF-1 expression has been described in tumors from other sites. The presence of TTF-1 expression in primary brain tumors is largely unclear and has not been clearly specified yet.

Voltage-gated sodium channel activity promotes prostate cancer metastasis in vivo.

Epigenetic upregulation of voltage-gated sodium channels (VGSCs) has been reported in a number of carcinoma cell lines and tissues. Furthermore, a large body of experimental evidence suggested that functional VGSC expression enhances various in vitro cell behaviours, such as directional motility, that would be involved in the metastatic cascade. However, it is not known if VGSC activity promotes metastasis in vivo.
