Radiotherapy had another active week on LinkedIn, with updates across pediatric radiotherapy, head and neck cancer, rectal cancer, pelvic oncology, prostate cancer biomarkers, SGRT, cervical cancer elimination, patient awareness, and personal reflections from the field.

Several posts highlighted how the field is advancing through collaboration and education. Lisbeth Cordero Mendez shared a new IAEA and St. Jude publication focused on strengthening pediatric radiotherapy training worldwide, while Sebastian Adeberg shared updates from the 3rd Marburg Head and Neck Symposium, covering immunotherapy, local therapy options, diagnostics, and interdisciplinary tumor board discussions.

Clinical research and innovation were also strongly represented, including real-world outcomes with dose-escalated total neoadjuvant therapy for rectal cancer, new work on immunological and inflammatory biomarkers in prostate radiotherapy, and C-RAD’s focus on surface-guided radiation therapy at ESTRO Meets Asia.

Global access remained an important theme, with the Elekta Foundation hosting discussions with African ambassadors on accelerating cervical cancer elimination through HPV screening, treatment access, and country-specific implementation.

The week also showed the human side of radiation oncology, from reflections on motherhood and pediatric cancer care to patient awareness campaigns and storytelling beyond the clinic.

Together, these posts reflect a field moving forward through technology, evidence, education, advocacy, and people-centered care.

Here are some radiation oncology posts worth catching up on this week.

Lisbeth Cordero Mendez – MD, MBA,Radiation oncologist en International Atomic Energy Agency (IAEA)

Aware of the multiple challenges faced by Children with cancer; IAEA and St Jude embarked on a mission to support Paediatric Radiotherapy worldwide, identifying the gaps in education and training for staff involved in the treatment of children with cancer with radiotherapy. In a joint effort to address these gaps our first publication is ready!

The aims of this publication are:
-To highlight to national and local policy makers, health administrators, health
professionals, patients and caregivers, and other stakeholders the importance of education and competence for health professionals in paediatric radiotherapy to improve cancer outcomes in general;
-To recognize that competent radiation therapy professionals are essential for accurate childhood cancer care;
-To empower radiation therapy educators to enhance paediatric specific content in their programmes and to guide education professionals and administrators in training
scientifically knowledgeable, technically skilled and clinically competent

Sebastian Adeberg – Professor and Director of the Clinic for Radiotherapy and Radiation Oncology – UKGM and Marburg Ion-Beam Therapy Centre (MIT)

Super exciting evening….we brought experts from Hessen together at our 3rd Marburg Head and Neck Symposium yesterday!

Updates on immunotherapy, local therapy options and diagnostics, followed by an interdisciplinary live Tumorboard.

Many thanks to all speakers and participants! Special thx to Merck for the support

Belén Navarro-Rubio Coello – Radiation Oncologist at UT MD Anderson

There are days in this specialty that run long, and nights on call that run longer.

On some of them my daughters come to see me. It sounds like a small thing and it isn’t: twenty minutes in a corridor with three (now four!) children who have no interest whatsoever in what I do for a living resets something that coffee does not. They’re also my biggest fans!

Being a mother is also, honestly, part of what drew me to pediatric radiation oncology. Not in a soft way. It made the logic of the field legible to me in a way it hadn’t been before. The trade-offs in pediatrics are not made against months of survival. They are made against decades of a life that has not happened yet. Not to mention the lives of the families of the little ones.

It is also, without a doubt, the hardest work I have done. There are tolls that one is only willing to pay because this field is truly a calling; a mission, not just a practice.

Paul Sargos – Radiation Oncologist at Institut Bergonié

Bravo Kanta Ka
Radiation therapy and immunity in prostate cancer:

Very pleased to share our published review on immunological and inflammatory biomarkers in patients with localized or locally advanced prostate cancer treated with radiotherapy.

👀 In particular, we explore the role of NLR, CRP, cytokines, tumor microenvironment, ctDNA and other emerging biomarkers.

This is a promising field for better understanding the response to radiotherapy and moving towards **precision radiotherapy**, even if clinical validation is still necessary for most of these markers.

Congratulations to the whole team for this international collaborative work!

Lacy Hubbard – President and CEO of Elekta Foundation

Five African countries, one shared ambition: accelerating #CervicalCancerElimination

Yesterday, it was a real pleasure to host the Ambassadors of #Rwanda, #Kenya, #Tanzania, #Zimbabwe, and #Nigeria to the #Nordics at the Elekta Foundation for a conversation about how we can turn this shared ambition into action.

We know how to prevent cervical cancer for adult women. We have the tools for screening and effective treatment for precancer. The challenge is making these tools accessible to every woman who needs them.

Our discussion focused on practical questions: how to expand access to affordable, quality-assured #HPVscreening, strengthen the pathway from screening to treatment, mobilize resources, and adapt solutions to the needs and cancer care systems of each country.

Rwanda has shown us what becomes possible when political commitment, local ownership, and practical implementation come together. Now there is an opportunity to take those lessons further, while recognizing that every country will need its own approach.

Five countries. Different contexts. A shared goal: making cervical cancer elimination a reality.

Thank you to Their Excellencies and colleagues from Rwanda, Kenya, Tanzania, Zimbabwe, and Nigeria for such an open and forward-looking discussion. The opportunity is in front of us. Now we need to turn shared ambition into measurable progress!

Lydia Lantz – Student at Brigham Young University Marriott School of Business

I recently wrapped up an incredible summer interning at Varian, a Siemens Healthineers company. I loved supporting the Radiation Oncology and Digital Oncology business lines, where I developed my skills in reconciling financial data and setting strategic financial targets. A special thank you to Colin C., Daniel Martin, Macy Gwilliam, and many others for their invaluable mentorship and support over these past few months!

Peter Gorayski – Radiation Oncologist at Royal Adelaide Hospital, Icon Group & SAHMRI. Associate Professor at University of South Australia

We’re aiming for precision…and a milestone!

As Chair of the Targeting Cancer campaign, I spend a lot of time talking about targeted treatment, accurate beam alignment, and hitting precise goals.

Today, we have a very specific non-clinical target in our sights: Crossing 2,000 followers on our LinkedIn page!

Did you know that 1 in 2 cancer patients could benefit from radiation therapy, yet many still miss out simply due to a lack of awareness? Every single follow helps us amplify vital information, support patients, educate GPs, and advocate for life-saving radiation oncology treatments across Australia and New Zealand and beyond!

We are this close to hitting our 2k mark.

How you can help us hit the bullseye:
Follow the page: Radiation Oncology: Targeting Cancer
Tag a colleague in the oncology or healthcare space who should be in our network!
Hit ‘Repost’ to spread the word.
Help us hit 2,000 so we can keep hitting cancer where it matters most!

Yoo Young (Dominique) Lee – Radiation oncologist, researcher and founder of HeyBoss!

Dear friends in Melbourne, I’ll be doing two book events this Sat.

At 11am, I’ll be at Amplify Bookstore in conversation with Grace Chan, author of Every Version Of You in their Reading Room at 55 Peel St, West Melbourne. Tickets (general admission or GA + book) are on their site — link below.

Then at 3pm, I’ll be hosting a more intimate afternoon at The Langham, Melbourne — Little Yarra Room, 1 Southgate Ave, Southbank. This one’s mine — I organised it myself, and it’s free to attend. A chance to sit with the story a little longer, and talk about what it takes to turn silence into strength.

I hope to see some of you there.

Amplify Bookstore, 11am

The Langham, 3–5pm
