#ASCO26
The PROTEUS trial results are now online...buckle up as we wait to see the full presentation. This is going to be a trial that is likely highly controversial until the full results are published.
Some may call this a homerun, others may call this the largest negative trial @ASCO 2026. Up to you to interpret!

I am excited to share our multi-institutional F-SHARP phase I/II trial, now published in @JCO_ASCO!
doi.org/10.1200/JCO-25-02730
There are limited prospective data defining the optimal management of intraprostatic radiorecurrence (IPR) after definitive RT for prostate cancer.
We asked:
1. Is dose-escalated focal salvage high dose rate brachytherapy safe and effective for IPR?
2. Can Decipher (@Veracyte) identify patients with higher risk of recurrence with salvage ReRT that may benefit from therapeutic intensification?

Every cancer organ gets the same sequence: surgery is the standard, then trials show you often don't need it, then surgery becomes the salvage.
Breast, larynx, limb, rectum, esophagus, mesothelioma.
Bladder is next. Patients want their organs. 🧵

Thrilled to share that the The American Radium Society (ARS) Benign Committee has just published our new Appropriate Use Criteria (AUC) on Low-Dose Radiotherapy for the Treatment of Inflammatory Periarticular Disorders, covering conditions such as plantar fasciitis, shoulder tendinopathy, and greater trochanteric pain syndrome.
As Vice Chairman of the committee, I am incredibly proud of the dedication, quality, and momentum our team has maintained over the past six months.
A special thank you to Suzanne Russo and Austin Dove for their exceptional leadership throughout this initiative, and huge congratulations to Austin Kirschner, MD, PhD for leading this particular publication to completion!

Surgery vs Radiation for Prostate Cancer: New PACE-A Trial Results
I discuss the randomized trial presented at #ASTRO26 @ASTRO_org
Kudos @nickva1 @alison_tree et al

Importantly this is modern data that with a spacer gel and SBRT at 2 years 80% of men remain potent.
This is in a prospective RCT with patient reported outcomes.
🧐nerve-sparing prostate RT?

☢️ #ASTRO26: LDRT in knee OA is fascinating.
292 patients | 4.5 Gy/10 fractions
At 3 years:
🦵 VAS pain: 21 vs 55
📈 Responders: 69% vs 25% (p<0.0001)
Long-term: disability 14% vs 25%; KL-2 knee replacement 14% vs 36% (HR 0.32, p=0.021).

Long-term PACE-A data at #ASTRO26 (van As LBA32, Yasar LBA10): the first randomized comparison of prostatectomy vs SBRT, 36.25 Gy in 5 fractions.
These are contemporary surgical data: all prostatectomies were laparoscopic, 84% robotic.
Using ≥1 pad/day, RP vs SBRT:
• 2 years: 50% vs 7%
• 5 years: 48% vs 8%
Sexual function at 5 years:
• EPIC sexual domain: 62→17 after RP vs 79→58 after SBRT
• Median IIEF-5: 5 vs 19
Important caveats: as-treated analysis, approximately 60% PRO completion at 5 years, baseline sexual function imbalance, and enrollment of 123 of a planned 234 patients.
Biochemical control looks similar through 8 years, but 13 events cannot establish equivalence.
For shared decision-making, these are numbers I’d want patients to see. Every patient considering prostatectomy should have the opportunity to meet with a radiation oncologist before choosing treatment.

I am pleased to share the results of our phase II randomized I-SABR study @ASTRO_org 2026 which demonstrate improved overall survival (OS) when adding four doses of immunotherapy to SABR in early-stage NSCLC. These exciting findings are associated with the persistent activation of cytotoxic T cells for up to 6.5 years. Further optimization of I-SABR approaches will guide future research and clinical practice.
Replying to @UTMDAnderson
Dr. Joe Chang shared six-year data from the Phase 2 I-SABR trial. He also shared that patients who received both nivolumab and SBRT treatment showed increased activity of cancer-targeting CD8+ T cells: spr.ly/6018BGWA4O (2/2) #ASTRO26 #EndCancer

1)RADICALS did not randomize dose regimens
2)Dose escalation relative to what? What are actual alpha/beta’s?
3)Hard to see how a trial showing worse outcomes with hypofractionation strengthens the case for hypofractionation
Replying to @lauren_henke
SO, the GU-003 data could continue to look worse with time as f/u matures, because of the DOSE ESCALATION. 📉 These data don’t kill hypofrac, they just strengthen the case for 52.5 Gy/20 fx, as used in RADICALS, to be preferred hypofrac postop regimen—shorter tx **without the dose escalation** used in GU003. #ASTRO26 #ProstateCancer

ROAM/EORTC-1308, ya en Lancet: radioterapia frente a observación después de una resección completa (Simpson 1–3) de meningioma atípico grado II 🧠 #btsm #radonc
A cinco años, la supervivencia libre de enfermedad fue 79,9 % con RT y 64,3 % con observación. Recidivaron el 14 % frente al 30 %. El riesgo se reduce a la mitad (HR 0,51).
📌No hubo diferencia en supervivencia global, pero hubo pocas muertes y el seguimiento aún no permite responder esa pregunta.
📌Calidad de vida y cognición no mostraron diferencias claras; a largo plazo faltan muchos datos.
📌Uno de cada siete pacientes asignados a RT no llegó a empezar el tratamiento. No se excluyeron: en el análisis principal siguen en el brazo de radioterapia, así que el beneficio, si acaso, está algo infraestimado. Cuando se analiza solo a quienes sí se irradiaron, el efecto va en la misma dirección pero pierde significación.
📌Simpson 1 no es un Simpson 3. El ensayo los agrupó como resección completa y de Simpson 3 apenas hay once pacientes. Al ajustar por grado de Simpson, la RT sigue beneficiando. No hay números para tratar por separado un 1 y un 3.
📌La clase de metilación y el IntS sirven para estimar quién recae más. No sirven para decidir quién se libra de la RT: el beneficio se mantiene al ajustar por biología. Un IntS bajo recae menos, no deja de recaer.
📌En observación, el riesgo del ensayo es alto: 30 % de recidiva y unos 36 % de eventos a cinco años. Aun así, cerca del 70 % de los observados no había recaído a los cinco años.
❓Es adyuvancia automática. Hay que ofrecerla. Observar puede ser razonable si la resección fue Simpson 1, el lecho es fácil de vigilar y de rescatar, la biología es favorable cuando se conoce, y el paciente acepta el riesgo de una reintervención.❓ Si falta alguna de esas condiciones, o prioriza no recaer, la radioterapia es la opción más respaldada .

I don’t think this is a controversial statement. The evidence is fairly clear cut now, especially for patients with cribriform pattern. Surgery should be reserved for severe LUTS cases #ASTRO26 #PCSM #SBRT #SABR #Radonc
Controversial statement by @SJFrankMD, informed by the ProtecT study results, for those who still think prostatectomy is the better treatment. #ASTRO26
