Purpose:
To evaluate the efficacy and toxicities of skin-directed radiotherapy (RT) in primary cutaneous T-cell lymphoma (CTCL).
Materials and Methods:
We retrospectively analyzed 57 CTCL lesions treated with skin-directed RT between January 2000 and December 2022. Lesions were categorized into three distinct groups: early-stage disease treated with local RT, advanced-stage disease treated with local RT, and advanced-stage disease treated with total skin electron beam therapy (TSEBT). Treatment outcomes, including response rates, recurrence patterns, and local progression probability, were assessed for each group.
Results:
Mycosis fungoides (MF) constituted 90.9% of the advanced-stage pathologies, while CD4+ primary cutaneous small/medium T-cell lymphoproliferative disorder was common in the early stage lesions (55%). Median RT doses were 30.6 Gy, 27 Gy, and 32 Gy for the local RT with early stage, the local RT with advanced stage, and TSEBT with advanced stage, respectively. The complete response rates were high across the groups: 95.5%, 70.8%, and 90.9%, respectively. Seven local recurrences (29.2%) occurred in the local RT group with advanced stage, while seven patients (63.6%) in the TSEBT group experienced local failure. All recurrences were observed in lesions and patients with MF. Acute toxicities were mainly grade 1 or 2, with no grade 3 or higher events. No significant association between RT dose and local progression rates in MF lesions was found.
Conclusion
Skin-directed RT in CTCL is effective for local control and well-tolerated with less toxicity.

Purpose:
This study aimed to evaluate the utilization and outcomes of resuscitative endovascular balloon occlusion of the aorta (REBOA) in managing noncompressible torso hemorrhage (NCTH) among trauma patients in Korea. The evolution of REBOA and its impact on patient survival was investigated as well as predictors of mortality.
Methods:
This retrospective study included 234 post-REBOA patients from 5 leading regional trauma centers across Korea between 2016 and 2021. Primary outcomes were in-hospital mortality, and secondary outcomes were various clinical parameters regarding REBOA, overall treatment flow, and complications. For comparative analyses, patients were dichotomized into in-hospital non-survivors or survivors. Then, generalized additive and linear regression models were used to evaluate the trend of in-hospital mortality.
Results:
The overall in-hospital mortality was 65.4%. The survivors had a higher proportion of responders following REBOA (87.7% vs 62.7%, p < 0.001). Key variables influencing outcomes included total occlusion time, red blood cell transfusion volume within the first 24 hours, revised trauma score, and systolic blood pressure gap. These factors significantly correlated with mortality rates in multivariate logistic regression.
Conclusion
Over 6 years, survival rates for NCTH patients undergoing REBOA in Korea have shown improvement. Despite diverse REBOA protocols across institutions, the results underscore the need for continued research, standardized practices, and national quality control measures to further optimize patient outcome and establish more effective treatment protocols for NCTH.
