ABSTRACT
BACKGROUND/AIM:
Esophageal and gastro-esophageal junction cancer is a major cause of cancer-related mortality, with poor prognosis. Toll-like receptors (TLRs) play a significant role in the innate immune system; their increased expression has been associated with esophageal adenocarcinoma. This study aimed to determine the association between TLR-3 and TLR-4 expression with clinical and oncological outcomes of patients that underwent esophagectomy for cancer. PATIENTS ANDMETHODS:
This is a retrospective analysis of prospectively collected data from consecutive patients within a 2-year period. Primary endpoints of the study were the assessment of the expression of TLR-3 and TLR-4 in primary tumors as well as in metastatic lymph nodes. Secondary endpoints were the correlation of TLR-3 and TLR-4 values with the clinical, pathological, and oncological outcomes.RESULTS:
A significantly higher expression of TLR-3 and TLR-4 in primary tumors and metastatic-lymph nodes was observed. There was a significant association between TLR-3 expression and T-stage, as well as TLR-4 expression and grade of differentiation in the primary site. Additionally, metastatic-lymph node TLR-4 expression was significantly correlated with N-stage. A strong correlation between TLR-4 expression and overall or progression-free survival rates was detected.CONCLUSION:
This study found a significantly increased TLR expression in malignant tissue/metastatic lymph nodes, as well as a significant positive correlation between TLRs and worse clinical outcomes. TLRs have a pivotal role in the inflammation pathway in the esophagus and during esophageal carcinogenesis. This study highlights the need for further investigation into TLR-mediated signaling pathways and their potential role as diagnostic and therapeutic targets.Palavras-chave
