Professor Young-Gyu Eun's research lab focuses on head and neck oncology, with a strong emphasis on the molecular and microbial mechanisms underlying oral squamous cell carcinoma (OSCC) and thyroid cancer. The lab investigates the role of the oral microbiome in modulating cancer progression and metastasis, particularly lymph node involvement, and explores genomic drivers such as YAP1 activation in head and neck squamous cell carcinoma (HNSCC). Additionally, the lab contributes to clinical innovation through minimally invasive surgical techniques, such as intraoral removal of submandibular stones and evidence-based tonsillectomy strategies for recurrent peritonsillar abscess. Their work integrates multi-omics analysis with clinical validation to improve diagnostic prediction and therapeutic outcomes.

Oral microbiota can alter cancer susceptibility and progression by modulating metabolism and inflammation. We assessed the association between the oral microbiome and lymph node (LN) metastasis in oral squamous cell carcinoma (OSCC). We collected a total of 54 saliva samples from patients with OSCC before surgery. LN metastasis was assessed based on postoperative pathological examination. We used QIIME2, linear discriminant analysis effect size (LEfSe), and PICRUSt2 methods to analyze microbial
Contralateral paratracheal LN metastasis is associated with ipsilateral paratracheal LN metastasis. This information may help to determine the optimal extent of prophylactic central LN dissection in patients with PTC.
By analyzing the genomic data of head and neck squamous cell cancer (HNSCC), we investigated clinical significance of YAP1 activation. Copy number and mRNA expression of YAP1 were analyzed together to assess clinical relevance of YAP1 activation in HNSCC. The clinical significance of YAP1 activation was further validated in four independent test cohorts. We also assessed the correlation of YAP1 activation with genomic alterations such as copy number alteration, somatic mutation, and miRNA expres
Intraoral removal of proximal submandibular stones has several advantages over SMG resection. Based on our results, we suggest that our intraoral removal method be selected as the primary procedure for the removal of proximal submandibular stones rather than SMG resection.
Our results suggest that tonsillectomy may be indicated as a treatment for peritonsillar abscess in patients with a history of recurrent tonsillitis or extraperitonsillar spread on computed tomography.
Among the laryngoscopic findings used in the RFS, subglottic oedema is specific for non-acid reflux episodes, and granuloma/granulation is specific for acid reflux episodes.
Routine CT might be suggested for diagnosis of epiglottic abscess in the patients with acute supraglottitis, because of the poor predictive values of symptoms and signs.
Significant improvements in subjective symptoms and ESS were found at 4 weeks after multilevel surgery. No significant change in BMI was observed. Adiponectin level was significantly increased after surgical treatment. Postoperative leptin, IL-6, and TNF-α levels were significantly decreased. The percent changes of adiponectin, leptin, IL-6, and TNF-α after multilevel surgery were not significantly different among patients with mild, moderate, and severe OSA.
The rs2227485 SNP in IL22 might be associated with the risk and the multifocality of PTC.
Follicular dendritic cell sarcoma (FDCS) is unusual, and those with an extranodal origin in the head and neck region are extremely rare. To date, no cases of tumors featuring the characteristics of follicular dendritic cells were reported in Korea. We report a new case of FDCS of the tonsils in a 65-year-old man. A diagnostic tonsillectomy was performed. Based on histopathologic and immunohistochemical findings, the patient was diagnosed with FDCS. Adjuvant radiotherapy was performed due to a hi
We found that the pharyngeal BI levels were higher in patients with LPR than in healthy controls. In addition, the pharyngeal BI levels measured by 24-hour MII-pH monitoring in patients with LPR symptoms, but without a reflux episode, were higher than in the healthy controls.
