Excited to share that my co-authored article on low-level laser therapy for reducing severe radiation-induced oral mucositis is now published online. I contributed to this work through our department's Quality of Life team. doi.org/10.1002/lsm....

A phase 2 trial demonstrated an isotoxic improvement in #cancer control with prostate-specific membrane antigen positron emission tomography-guided intensification of salvage RT after radical prostatectomy. ja.ma/48tWkkb

Rockstar #radonc @mskcancercenter.bsky.social resident Dr Kaitlyn Lapen presents at #ASTRO25 on quality of life improvements with early radiation for asymptomatic bone metastasis which may appear after 6 months. Optimal patient selection is key. @astro-org.bsky.social

ASTRO Annual Meeting for this year is now over, but can I have my ASTRO everyday? (no 😅) #ASTRO25

My Korean colleagues! #ASTRO25

Dr. Cheng reported 30Gy/26Gy/5fx SIB tumor bed boost for whole breast irradiation on behave of her colleagues in Beijing. I have a few words for this. #ASTRO25

Trials presented in the plenary section clearly leave some debatable questions. #ASTRO25

Primary outcomes of NRG GU005 study will be presented soon in the plenary session, though for the secondary outcomes there are some discrepancies between already-published studies for prostate cancer SBRT. I wonder why… #ASTRO25

Dr. Sang Hoon Seo, a resident physician of Samsung Medical Center Department of Radiation Oncology, presented blood dosimetry models in craniospinal irradiation, suggesting that blood DVH D5% can be a predictor of worse survival. Great job! #ASTRO25

LoRD-KNeA trial observed efficacy of low-dose RT in knee arthritis. 4-month response rates were 58.3% (0.3 Gy) vs. 70.3 (3 Gy) vs. 41.7% (0 Gy, sham), provides objective evidence for the efficacy of low-dose RT. Really proud of prof. Byoung Hyuk Kim! #ASTRO25

New results from trials for prostate cancer treatment: NRG GU006 BALANCE, LUNAR, and NRG/RTOG 0924. Kudos for the results! #ASTRO25

I’ve checked out this year’s posters from Sang Hoon Seo, who is currently a resident physician in my institution. He will make an oral presentation for another abstract in the CNS section today. Very enthusiastic, isn’t he? #ASTRO25

Me at #ASTRO25

Since check-in time for my hotel isn't here yet, I decided to get my badge a little earlier. A bit disheveled because I just arrived in SF an hour ago, but who cares! #ASTRO25

On the way to the airport for #ASTRO2025. Nice weather even in Seoul!

Our breast cancer multidisciplinary team got together and had a great time—barbecue, good vibes, and even some karaoke to top it off!

Transgender and gender-diverse patients with breast cancer receive less endocrine therapy and have lower 5-year overall survival compared to cisgender patients. ja.ma/4mbpqZ0

Great work. As a professional we need to understand certain aspects of underrepresented populations as well.

My co-authored article is now online! It’s from a multi-institutional collaboration group in Korea, discussing who should receive prophylactic cranial irradiation in limited-stage small cell lung cancer. doi.org/10.6004/jncc...

I think I can visit ASTRO 2025 this year.

I visited the Heavy Ion Therapy Center at Severance Hospital for the KROG Symposium on Breast & CNS Cancer. About 80–90% of the participants attended the lectures online.

I visited Heavy Ion Therapy Center of Severance Hospital for KROG Symposium for Breast & CNS Cancer. 80-90% of participants were hearing the lectures by online.

Starting to July, I’m going to receive patients with genitourinary cancer in my clinic.

In women with node-positive breast cancer whose nodes became free of disease after neoadjuvant therapy, regional nodal irradiation did not reduce breast cancer recurrence or improve survival. Full results from a phase 3 trial: nej.md/4dM6LjD #MedSky #Oncology

Soon after I came back to Korea from ESTRO 2025 at Vienna, I am in the port city of Busan for Spring Meeting of the Korean Society for Radiation Oncology!

Congratulations to EMBRACE Collaborative Group for Donal Hollywood Award! EMBRACE trials set the clinical standard for cervical cancer RT. #ESTRO25 #ESTRO2025

I listened to this lecture. It’s a physics lecture though I should know what is going on in the auto-segmentation and auto-planning for breast cancer RT, as this change will be inevitable. Interesting schemes for implementing those! #ESTRO25

Hey, I should remember this, ESTRO Asia 2026! #ESTRO25

I definitely agree that de-escalation is optimization and should be patient-centered!

Very interesting talks for RT for early breast cancer! #ESTRO25

Hello, ESTRO! #ESTRO2025 #ESTRO25

My co-authored article gets online. I contributed this study for the analysis and the revision of the manuscript. Our team is running a multi-center prospective study for quality of life assessment for cancer survivors who underwent RT, expanding the observations. doi.org/10.1007/s005...

I delivered a presentation in the education session of GBCC 2025, regarding the optimal strategy to combining radiation and breast reconstruction. Let’s remind that with careful approach, radiation-related complications for reconstruction can be minimized!

Welcome Dinner of GBCC 2025 was marvelous!

Dr. Jagsi made a great lecture for evolving roles of tailored radiation therapy for breast cancer. While everyone is talking about omitting radiation recently, Dr. Jagsi emphasized the role of partial breast irradiation as well as that of regional nodal irradiation.

GBCC (Global Breast Cancer Conference) 2025, Grand Walkerhill Hotel, Seoul, Korea. This is a multidisciplinary breast cancer conference, and I already presented my abstract in here.

My new article is now online. It explores the effectiveness of a strategy for predicting 30-day mortality in patients undergoing palliative radiotherapy using blood tests and a gradient boosting mechanism. #RadOnc doi.org/10.1016/j.ra...

The Samsung Medical Center Radiation Oncology Alumni Symposium was held on January 10th at the Intercontinental Seoul Parnas Hotel. The symposium also served as a celebration of the retirement of Professor Yong Chan Ahn, a founding member of the department in 1994.

I forgot to post about a new co-authored article: Relationships between the Microbiome and Response to Neoadjuvant Chemoradiotherapy in Locally Advanced Rectal Cancer. Accepted at Cancer Research Treat on 2024 Dec 16. I helped Dr. Lee HI for analyzing sequencing data. e-crt.org/journal/view...

Surprised this article hasn't gotten more 👀 Inappropriate Denials for Radiation Therapy in Medicare Advantage Plans www.redjournal.org/article/S036... "These data warrant urgent policy changes to prevent Medicare-eligible patients from being inappropriately denied access to cancer treatments."

@natureportfolio.bsky.social highlights the mass migration of academics and researchers to Bluesky that is happening in these days But if good experts quit X, who will offer evidence-based input on X? @oncoalert.bsky.social www.nature.com/articles/d41...

Our favorate Int J Radiat Oncol Biol Phys starts to post in Bluesky!

Loving these Blue Skies🐦Thanks for Your Support🚨 @elisabettabonzano.bsky.social @elisaagostinetto.bsky.social @realbowtiedoc.bsky.social @tmprowell.bsky.social @erikahamilton9.bsky.social @elizsmckenna.bsky.social @viveksubbiah.bsky.social @stephenvliu.bsky.social @coffeemommy.bsky.social

Recent surge of users in Bluesky made me my account in here too. I think it will develop more.

My new article is now online (article in press) in @ijrobp.bsky.social. It discusses effect of cardiac radiation dose to cardiotoxicity risk of patients with breast cancer receiving trastuzumab. doi.org/10.1016/j.ij...

Hello, Bluesky!
