A Pilot Study of Extended Adjuvant Therapy with Metronomic Docetaxel for Patients with Operable Triple-Negative Breast Cancer.

Background: Triple-negative breast(TNBC) cancer is a molecular subtype of breast cancer with poor prognosis and did not get approved targeted therapy till now. In the last years, metronomic chemotherapy (mCTH) was investigated to improve treatment outcomes in TNBC patients both in early and metastatic setting due to its anti-angiogenic and immune-stimulatory mechanisms. The aim of this study is to evaluate the efficacy and safety of extended adjuvant chemotherapy with metronomic docetaxel for patients with operable TNBC.

Circulating methylated RUNX3 and SFRP1 genes as a noninvasive panel for early detection of colorectal cancer.

Objective: This study was conducted to assess the methylation status of runt-related transcription factor 3 (RUNX3) and secreted frizzled-related protein 1 (SFRP1) genes in paired tissue and serum samples of colorectal cancer (CRC), adenomatous, and control subjects and elucidate the association between methylation status on RUNX3 and SFRP1 mRNA expression.

Methods: Methylation status of RUNX3 and SFRP1 in paired tissue and serum samples and RUNX3 and SFRP1 mRNA expression in tissue from 85 patients with CRC, 40 with adenoma, and 40 healthy controls were determined using methylation-specific PCR and reverse transcription PCR.

Results: The frequency RUNX3 and SFRP1 genes methylation was significantly higher in both tissues and serum of CRC patients and was significantly associated with absence of its corresponding mRNA expression.

Genetic and epigenetic modifications of adiponectin gene: Potential association with breast cancer risk.

Background: Adipokines produced by adipose tissue are directly linked to obesity and may contribute to the pathogenesis of cancer. We hypothesized that genetic and epigenetic modifications in the adiponectin (ADIPOQ) gene and their impact on serum ADIPOQ levels may participate in increasing breast cancer (BC) risk. The present study aimed to investigate ADIPOQ +45 T/G gene polymorphism, methylation status at CpG sites -74 nucleotides (nt) and -283 nt of the ADIPOQ gene, and ADIPOQ serum levels in BC obese women.

miR-146a and miR-196a-2 genes polymorphisms and its circulating levels in lung cancer patients.

Recently, MicroRNAs polymorphisms and their serum expression have been linked to increase risk of various cancers. The aim of this study was to elucidate the association between single nucleotide polymorphisms of miR-146a and miR-196a-2 and their serum expression and lung cancer risk. One hundred and twenty lung cancer patients and 120 health controls were included in this study.

Thioredoxin-Interact ing-Pro t e in [TXNIP] and Transglutaminase 2 [TGM2] Expression in Meningiomas of Different Grades and the Role of Their Expression in Meningioma Recurrence and Prognosis.

Background: Meningiomas are common central nervous system (CNS) tumors that account for thirty percent of primary intracranial tumors.. The accuracy of predicting meningioma recurrence and progression is not enough.

CYP1A1 gene polymorphisms and smoking status as modifier factors for lung cancer risk.

Objective: Lung cancer remains the most prevalent malignancy worldwide. Susceptibility to lung cancer has been shown to be modulated by inheritance of polymorphic genes. Several metabolic enzymes are currently under investigation for their possible role in lung cancer susceptibility, including members of the cytochrome P450 (CYP) superfamily.
