BACKGROUND
Lately SOX2 and SOX9, transcription factors associated with stemness-like phenotypes of cancer cells, have been linked to tumor growth, metastasis, and resistance to therapy.
METHODS
This study aimed on evaluating the expression of SOX2 and SOX9 in a large cohort of patients with OSCC including primary and recurrent tumors and corresponding lymph node metastases. Semiautomatic digital pathology scoring was used to determine protein expression and survival analysis was performed to evaluate its prognostic significance.
RESULTS
We found a significant downregulation of SOX9 from primary disease to lymph node metastases (p < 0.001). SOX9 expression and the subgroup SOX2SOX9 were significantly correlated with worse overall survival (p < 0.05). Additionally, SOX2SOX9 expression pattern was confirmed as independent prognosticator for overall survival.
CONCLUSIONS
These results indicate the relevant role of SOX2 and SOX9 in patients with OSCC and show the clinical relevance for further investigation on the molecular mechanisms underlying SOX-related gene expression.
背景
最近，与癌细胞干性样表型相关的转录因子SOX2和SOX9已被证明与肿瘤生长、转移及治疗耐药性有关。
方法
本研究旨在评估一大群口腔鳞状细胞癌（OSCC）患者中SOX2和SOX9的表达情况，这些患者包括原发性肿瘤、复发性肿瘤及相应的淋巴结转移灶。采用半自动数字病理评分法确定蛋白表达，并进行生存分析以评估其预后意义。
结果
我们发现从原发性疾病到淋巴结转移，SOX9显著下调（p < 0.001）。SOX9表达及SOX2SOX9亚组与较差的总生存期显著相关（p < 0.05）。此外，SOX2SOX9表达模式被确认为总生存期的独立预后因素。
结论
这些结果表明SOX2和SOX9在OSCC患者中具有重要作用，并显示出进一步研究SOX相关基因表达潜在分子机制的临床意义。
