At the time when MD Anderson celebrated its 75th anniversary, President Biden attended our celebration and gave a talk about moonshot projects to conquer cancer. President Bush (Senior) was also present.

President Biden’s PSA screening was done 10 years ago and never repeated until he had symptoms. For a prominent person with so much important responsibilities, should we screen for PSA? How should we individualize personal cancer screening?

Neoadjuvant chemo/IO improved OS in operable NSCLC 5-OS: 95% in pts with cPR 75% in pts with negative ctDNA before surgery 10-20% can not have surgery after induction TX 10% has positive margin 10% needs post-OP RT Organ preservation options after Chemo/IO? cPR prediction?

This is a randomized study to validate our colleague David Qian’s published hypothesis: IO injection at early time of the day IO is better than later time. Can we hypothesize: Early time of SBRT/SABR delivery is better than later time of the day?

Structured exercise or healthy diet can improve overall survival in any populations with or without cancer. The challenge is how to motivate ourselves to change our habits, particularly for Americans (Top in medical expenses and inventions, but not in life expectancy).

First phase III randomized study showed an improvement in overall survival with proton-based IMPT compared to photon IMRT in head and neck cancer. This was presented today during the The Particle Therapy Co-Operative Group (PTCOG) plenary session by Steven J. Frank, MD. The exciting data provides justification for IMPT.

Learn from negative studies: Negative studies should not be ignored. Negative studies may result from : A. futile hypothesis B. inappropriate study design: sample size endpoints the immaturity of technology PSPT vs IMPT: different generations of PT The Particle Therapy Co-Operative Group (PTCOG)

SACRAL CHORDOMA: Particle RT vs. Surgery Prospective SACRO Study Presented by Dr. Fossati No significant differences in PFS, OS, or local/distant failure. Although patients receiving RT had worse tumor locations, they showed numerically better outcome and lower toxicity.

Why Particle TX? Why Flash RT? We must continue exploring novel technologies to overcome current TX obstacles. Yesterday’s “experimental treatment” has become today’s “standard of care” such as IMRT, SBRT, and IO …… Aim to create better, cheaper and faster RT for future.
