SBRT vs microwave ablation (MWA) in pts with CRC liver oligo-mets
➡️ n=100, n=92 treated (39 SBRT, 53 MWA)
➡️ 18/92 pts (20%) reported side effects
➡️ n=3 G3-4 pain; n=2 infections after open MWA, n=1 bowelperforation after percutaneous MWA

PD-1 and PD-L1 Blockade With Chemotherapy for Borderline Resectable and Unresectable Stage III Non–Small Cell Lung Cancer This cohort study evaluates the efficacy of neoadjuvant programmed cell death 1 protein (PD-1) or programmed cell death 1 ligand 1 (PD-L1) blockade combined with chemotherapy in enhancing surgical out...

Neoadjuvant chemo-IO for Borderline Resectable & Unresectable Stage III NSCLC

Conclusion of authors: "high rates of surgical resectability"

Pts with completed surgery:
III A: 65/79 - 82%
III B: 16/27 - 59%
III C: 3/6 - 50%

-> careful interpretation needed

Thought provoking !
Population-health impact of new drugs recommended by NICE in England during 2000–20
- quality-adjusted life-years and incremental cost-effectiveness ratio used for analysis
👉 overall NEGATIVE (!) cumulative impact
👉 data for #radonc ?

Retrospective multicenter study of SBRT for pulmonary oligometastatic HNSCC
- 16 centers, 178 pts, 284 pulmonary mets
- 1a local failure rate 5.5%
- no grade 4/5 toxicities

Aiming to refine your #radonc in 2025 !

Offer RT for low-volume metastatic PC, only ?
What benefit of RT is to be communicated to pts & colleagues ?
How about SBRT or surgery ?

Season's Greetings

Radiation Myelitis After Hypofractionated Spine Stereotactic Body Radiation Therapy This cohort study characterizes the risk of radiation myelitis after spine stereotactic body radiation therapy to update the current dosimetric constraints.

Safe practice of spine SBRT requires high-quality data about SC dose tolerance
- Cohort study 2051 pts
- 30 cases of RM, 19 of which G3 to G4
- 2a rate of G1-4 RM 1.8%
- cord dose D0.1cc of 19.1Gy / Dmax of 20.8Gy = 1.0% risk of G3 to G4 RM at 2 years

Stereotactic Body Radiotherapy vs Sorafenib Alone in Hepatocellular Carcinoma This phase 3 randomized clinical trial evaluates whether stereotactic body radiation therapy improves outcomes in patients with locally advanced hepatocellular carcinoma compared with sorafenib alone.

Todas is HCC day!
- RTOG 1112
- HCC unsuitable for or refractory to local-regional Tx (n=177)
- SBRT & Sorafenib vs Sorafenib
- After adjustment for stratification factors, improved OS after SBRT (HR 0.72)
- Median PFS improved from 5.5 to 9.2 mo (HR 0.55)
jamanetwork.com/journals/jam...

And yet another prospective trial confirming excellent efficacy of SBRT for localized HCC
- n=36 pts
- median tumor size 2.3 cm
- median FU 49 mo
- 3-year local control rate 93%
- Grade 3 AE 11%

Radiofrequency Ablation Versus Stereotactic Body Radiotherapy for Recurrent Small Hepatocellular Carcinoma: A Randomized, Open-Label, Controlled Trial PURPOSETo assess the efficacy and safety of radiofrequency ablation (RFA) versus stereotactic body radiotherapy (SBRT) in treating recurrent small hepatocellular carcinoma (HCC).METHODSIn this trial, ...

Randomized comparison of SBRT vs RFA for recurrent small HCC (n=166 pts)
👆 Freedom from local progression significantly improved after SBRT: 2a 92.7% vs 75.8%, HR=0.45 !
👉 No difference in PFS (median 37.6 vs 27.6mo) and OS (2a 97.6% vs 93.9%)
👍
ascopubs.org/doi/10.1200/...

Remember the misleading press about "brutal" #radonc after PROSPECT ?

This is what modern RT can achieve for elderly breast cancer patients !
👉 "Endocrine Tx was associated with a greater reduction in HRQOL compared with RT at 24 mo"
👉 oncological data awaited

Radiotherapy of the prostate in metastatic pts prevents serious GU complications, in pts with low and high tumor burden

How to select patients?
- all ?
- based on live expectancy ?
- response to systemic Tx ?
- prostate volume ?
