Humbled. And also very proud that in 2015 we (@Ashworth_SF, @pvolberding, and @Hiatt4) made building a Global Cancer Program a Priority Initiative for @UCSFCancer. We have so much work still to do.

Honoured to publish an editorial in JCO GO accompanying a randomized trial on CRC survivorship in North Africa.
Key message: Exercise is not adjunct—it is treatment.
scalable interventions like physical activity may be among the most powerful tools to improve outcomes.

The True Meaning of Mentorship in Global Oncology | Dr. Katherine Van Loon

Dr. Katherine Van Loon, gastrointestinal oncologist, professor at UCSF, and recipient of the 2026 Conquer Cancer Foundation Women Who Conquer Cancer Mentorship Award, reflects on the meaning of mentorship and its role in shaping the future of global oncology.

In this video, Dr. Van Loon shares the emotional story of learning she had received the award, the international community of mentees who nominated her, and the values that guide her mentorship philosophy.

She discusses the importance of empowerment, impact-driven work, individualized training pathways, and building lasting relationships with mentees. Drawing on years of experience in global oncology, she explains why there is no one-size-fits-all model for training and leadership development.

🎗️ ASCO26 Final

🏆 From receiving the @ASCO IDEA 2026 Award to presenting our research, this year’s ASCO was a truly unforgettable milestone in my oncology journey.

🌍 I had the privilege of meeting and learning from some of the architects of modern oncology: Dr.Elizabeth Mittendorf (@ASCOPres), Dr. Daniel Hayes, Dr.@OtisBrawley, Dr.Nancy Davidson, Dr.@CliffordHudis, Dr.Howard Burris, Dr.@jrgralow, Dr.Robin Zon, Dr.@ManjuSengar7 Dr.@FeliciaKnaul, Dr. @KVanLoonMD, and Dr.@fumikochino

🤝 I was also fortunate to connect with inspiring physician-scientists and future collaborators, including Dr.@ravi_b_parikh, Dr.@CaPsurvivorship, Dr.@thenasheffect Dr.@PTarantinoMD Tarantino, and Dr.@NarjustFlorezMD .

🙏 My sincere gratitude to Prof. @DrYukselUrun and Prof. @RejinKebudi for their mentorship, guidance, and support. Their leadership continues to inspire young oncologists from Türkiye to engage with the global oncology community.

✈️ ASCO may be ending, but the journey continues. Next stop: Oklahoma City to visit Dr. @RyanNipp before returning home to Türkiye with new ideas, new friendships, and an even stronger commitment to advancing cancer care.

🇹🇷🌍 The journey continues.

Love this! 💙

✨ Every year I come to #ASCO26 for the science… but I leave forever changed by the people. 💙

The mentors who lit the path before I could see it. The colleagues who dare me to dream bigger. The friends who remind me that none of us walk this road alone. 🤗
We spend our days in clinic holding hope for our patients — and then we gather here, and something extraordinary happens. The exhaustion lifts. The fire reignites. We remember WHY we chose this. 🔥

Because behind every abstract is a patient praying for more time. 🙏 And behind every one of us is a community refusing to stop until we find the cure. 🧬🔬

I'm leaving rejuvenated, full of hope, and more determined than ever. 🚀

This is so much more than a meeting. It's a movement. And I'm so honored to be part of it. 💕

A remarkable doctor, scientist, mentor, and human being.

If you were unable to attend the #ASCO26 Opening Ceremony, be sure to watch Dr. Eric Small’s (@ASCOPres) President’s Address online. It was centered on his values, his drive for translation and innovation, his global vision, and his personal experiences growing up in Mexico and losing his lifelong partner to cancer.

We are fortunate to know you and to have such an inspirational leader at @UCSFCancer.

@ASCO @EnriqueSoto8 @sueyom

[Katherine Van Loon, MD, MPH @KVanLoonMD]

Ana I. Velazquez-Manana was honored with the Challenging the Status Quo Yvonne Award 2026 for her leadership in thoracic oncology, health equity, and inclusive cancer care.

Her work goes beyond treating lung cancer; it challenges the barriers that shape who receives timely testing, who enters clinical trials, and who feels represented in oncology.

Through her clinical work, research, advocacy, and mentorship, she continues to push the field toward a more accessible and accountable future for every patient.
