研究室紹介
Professor Dae Sik Yang's research lab specializes in clinical and translational radiation oncology, with a focus on improving radiotherapy outcomes for urological and gynecological cancers, including upper tract urothelial carcinoma and early-stage cervical cancer. The lab investigates advanced radiotherapy techniques such as stereotactic body radiation therapy (SBRT) and intensity-modulated radiotherapy (IABR), emphasizing treatment efficacy, local control, and complication management. Additionally, the lab contributes to the development and validation of predictive nomograms for survival outcomes, integrating clinical and imaging data to personalize treatment strategies. The research also extends to neuro-ophthalmological mechanisms, particularly the neural control of optokinetic nystagmus in animal models, highlighting interdisciplinary interests in physiological systems and their clinical implications.

15SBRT for UC tumors confers efficient LC, although the risk of complications was not negligible. Control of possible risk factors of hemorrhage and dose optimization through further studies are warranted.
A number of methods have proven to be useful for extended x-ray-absorption fine-structure data analysis of disordered systems. Regularization methods, which describe the radial distribution function nonparametrically, have the advantages of eliminating bias caused by modeling the distribution with a specific functional form, properly including spherical wave effects, and allowing the imposition of physical constraints in a systematic way. In this work we find empirically that the regularization
Background and objective: Although transarterial chemoembolization (TACE) has been the commonest local modality for hepatocellular carcinoma (HCC), incomplete repsonse occurs especially for tumors with a large size or difficult tumor accessment. The present meta-analysis assessed the efficacy and feasibility of external beam radiotherapy (EBRT) as a salvage modality after incomplete TACE. Materials and Methods: We systematically searched the PubMed, Embase, Medline, and Cochrane databases. The p
IABR showed feasible oncologic outcomes in 5-year follow-up. Adjuvant radiotherapy had little effect on quality of reconstruction. However, IABR in advanced stage should be cautiously applied considering expected survival and minor problems after IABR.
Background . Three nomogram models for early stage uterine cervical cancer have been developed (KROG 13-03 for overall survival [OS], SNUH/AMC for disease-free survival [DFS], and KROG 12-08 for distant metastases-free survival [DMFS]) after radical hysterectomy (RH) and pelvic lymph node dissection (PLND). This study aimed to validate these models using our cohort with adjuvant radiotherapy. Methods . According to the eligibility criteria of nomogram studies, patients were enrolled in Group A (
We studied postoperative status of 14 patients with myasthenia gravis of ocular type who underwent extended thymectomy. Nine patients were in remission, three improved, and two unchanged. No patient became worse and died. The remission rates at one, three, five, and ten years after operation were 50.0%, 58.3%, 60.0%, and 80.0%. The palliation rates at one, three, five, and ten years after operation were 64.3%, 75.0%, 80.0%, and 100%. The remission rate at one year after operation in patients of
Background: Idiopathic pulmonary fibrosis (IPF) has the potential to cause fatal pulmonary toxicity after radiotherapy and can increase the morbidity and mortality of non-small-cell lung cancer (NSCLC) patients. In this context, we aimed to develop imaging complexity biomarkers to predict the incidence of severe pulmonary toxicity in patients with NSCLC who have underlying IPF and are treated with radiotherapy. Methods: We retrospectively reviewed the medical records of 19 patients with NSCLC wh
Nasal or temporal side of the cat's retina was stimulated with nasalward and temporalward moving patterns for investigating the neural control of the optokinetic nystagmus in the direct and indirect pathways of OKN. The experimental data demonstrated that there was a nasalward directional preference in cat's OKN system under both close loop and open loop conditions, and the nasalward OKN gain evoked by stimulation of nasal retina was much higher than that at temporal retina. This indicates that
