Background: The expression of melanoma-associated antigen (MAGE) gene has been studied in many types of cancer. In the present study we evaluated the correlation between MAGE expression and the clinical features and oncologic outcomes of patients with papillary thyroid cancer (PTC).
Materials And Methods: We performed a retrospective review of 85 patients who underwent surgery for PTC and analysis of their tumor tissue by nested reverse transcription-polymerase chain reaction (RT-PCR) with the MAGE common primer to detect the MAGE A1-6 gene. The associations between MAGE expression and clinical characteristics were analyzed.
Results: Expression of MAGE A1-6 in PTC was identified in 31 patients (36.5%). Only papillary thyroid microcarcinoma (PTMC) was significantly related to MAGE expression in our univariate analysis (p=0.002) and multivariate analysis (p=0.006). MAGE had no significant impact on survival.
Conclusion: Expression of MAGE A1-6 in PTC is significantly correlated with the presence of PTMC. Our study suggests that MAGE expression may be related to early-stage PTC.

Objective: The objective was to evaluate the expression of melanoma antigen (MAGE) A from A1 to 10 (A1-10) and the individual MAGE A family in the peripheral lung tumors and to analyze its association with histopathological findings.
Methods: A cross-sectional study was conducted on 67 samples of peripheral lung tumor obtained by core biopsies from patients with clinical diagnoses such as lung and mediastinal tumors. The specimens were divided into two, one to perform histopathological diagnosis and the last for mRNA MAGE A examination.

Background/aim: The aim of this study was to detect circulating tumor cells (CTC) in the peripheral blood of gastrointestinal cancer patients using conditionally reprogrammed cell (CRC) culture.
Materials And Methods: We confirmed the sensitivity of the CRC culture method. Five ml of blood were obtained from 81 cancer patients (56 colorectal and 25 gastric).

The present study aimed to verify the efficacy of the conditionally reprogrammed cell (CRC) culture method for the detection of circulating tumor cells (CTCs) in breast cancer. CTCs were isolated from the peripheral blood of patients with breast cancer, and culture of the collected CTCs was performed according to the conditional reprogramming protocol. Total RNA was extracted from cultured CTCs, and the and genes were amplified using reverse transcription-PCR (RT-PCR).

A total of 76 blood samples from patients without malignant disease and 107 blood samples from patients with malignant disease were investigated for the presence of circulating tumor cells (CTCs). To detect CTCs, hematopoietic cells were removed from the blood samples and different RNA extraction methods were used to amplify the melanoma antigen-encoding gene family member A1-family member A6 (MAGE A1-6) and the human telomerase reverse transcriptase (hTERT) gene as potential CTC markers. Comparison between four methods for extracting RNA from the blood was performed.

The melanoma-associated antigen (MAGE) genes are known to be expressed in various kinds of tumors including lung cancer. Although they are studied as targets for immunotherapy and tools for early detection of lung cancer, the correlation between MAGE expression and the prognosis in lung cancer has not been clarified. In this study, we evaluated the relationship between MAGE A1-6 gene expression and the clinical prognosis in lung cancer.
