Amazing work, @Byoung_hkim!
Happy to share that our multicenter, randomized, sham-controlled phase II trial of low-dose whole-brain radiotherapy in mild-moderate Alzheimer’s disease is now published in Radiotherapy & Oncology! Why we did it: LDRT reduced amyloid and neuroinflammation in AD mouse models. Our two dose arms came from early human reports: a CT-dose case report (0.04 Gy; Cuttler et al., 2016) and a single-arm pilot (0.5 Gy; Kim et al., ROJ 2023). Neither had a control group. What we did: 41 amyloid-PET+ patients were randomized to sham, 0.24 Gy, or 3 Gy (6 fractions over 3 weeks), on top of standard medication. What we found: - 6-month ADAS-cog (primary endpoint) was not met - 12 months (exploratory), −5.4 points with 3 Gy (nominal p = 0.044), though findings were not consistent across other outcomes. No treatment-related adverse events. What’s next: LDRT was safe, but efficacy is not established. Larger, adequately powered trials with longer follow-up are needed, and we look forward to LDRT-MIND from Dr. Evan Thomas, which will add more robust data and explore maintenance. Grateful to our patients, and co-investigators across three centers. 🔗 doi.org/10.1016/j.radonc.202… #Alzheimers #LowDoseRT #ClinicalTrial @EvanThomas84 @jryckman3

Excited to share the updated long-term (12-month) results of our LoRD-KNeA trial! Building on our initial 4-month data, it is encouraging that significant clinical benefit was maintained up to 8 months following just a single course of LDRT 3 Gy/6 fx, even with a small patient cohort. We originally aimed for a more impactful general scope journal, but the review process turned out to be quite a long and challenging road. We look forward to addressing various discussion points at a future ASTRO webinar and/or in our subsequent analyses. While LDRT is not yet covered by insurance in South Korea, it is actively utilized in the US, and we anticipate more follow-up evidence emerging! 🇺🇸🇰🇷 #Osteoarthritis #LDRT

Great read, and more than a little scary. In the concluding paragraph: "I expect and hope for voluntary slowdowns to become commonplace until shared safety bars are established."

The bolus versus weekly cisplatin debate rages on, but fortunately more data dropped this past week with the publication of the ConCERT trial (Concurrent Chemotherapy and External Radiation Therapy) comparing bolus with weekly schedules. Some thoughts on this trial and the cisplatin schedules below. academic.oup.com/jnci/articl…

This study is now echoed by ConCERT in the definitive setting, with the caveat that the result may be mediated by improved tolerability rather than something biological. Results from the HPV-positive cohort in NRG HN009, a pure study of bolus versus weekly (40 mg/m2) with careful assessment of quality-of-life, were released in abstract form in February, and showed no difference in T-score (average number of grade 3-4 AE's) or locoregional recurrence. Yet clearly the types of AE’s were different, as bolus led to more acute kidney injury, hearing impairment, and dermatitis. There was more leukopenia, pain, anorexia and fatigue in weekly. Because weekly wasn’t superior, it didn’t move to a phase III, but I think that undersells its oncologic equivalence and, in my opinion, more favorable slate of side effects. The HPV negative HN009 results are still pending, but this cohort has accrued and hopefully will be reported soon. Interestingly, HN009 chose to deliver 3 cycles of bolus cisplatin with daily fractionation versus 2 cycles with accelerated fractionation. While it is an understandable decision based on the more routine practice of a 7 week course, we will still be left with the unknown comparison of just 2 cycles (and accelerated) versus weekly, which is a non-trivial difference since that third cycle can really lead the patient past the threshold of misery. Consider that the incidence of grade 2+ hearing toxicity was 23% vs 15% with 3 versus 2 cycles in RTOG 0129, and grade 2+ renal toxicity was 21% vs. 14%.

Here we are, over 20 years since the publication of the Intergroup trial, and where do we stand with cisplatin scheduling? In the postoperative setting, the JCOG 1008 study should shut the door on bolus cisplatin for adjuvant chemoradiotherapy. For definitive treatment, ConCERT, while it has many intrinsic flaws, makes a very reasonable argument that weekly cisplatin is at least as good, if not better, in both tolerability and even efficacy. This result is echoed by what we know from HN009 for HPV+ patients, and the two Indian randomized studies using 40 mg/m2 in HPV-negative patients. I deeply appreciate the history of bolus cisplatin, and it has improved the survival of many, many patients over the years. For certain patients, it may still be the right choice, especially if delivered for 2 cycles with accelerated radiotherapy to minimize its serious complications. But for the vast majority of patients, I see no reason to cling to the past. Acute renal failure can translate to some degree of chronic renal insufficiency, and the hearing loss and tinnitus can be very damaging to quality-of-life, even at grade 2… these are the side effects last for life. Both the JCOG and ConCERT trials show the difference in toxicity (and maybe efficacy) in the HPV-negative patient, and it’s a huge stretch to think that bolus cisplatin would be “better" for HPV positive patients, especially with the early results from HN009. It’s time to move past the bolus versus weekly question, and hopefully it’s done after HN009 is reported. Now we really need to focus on (a) the optimal systemic therapy for cisplatin-ineligible patients, (b) improving the efficacy of systemic therapy/radiosensitization for non-favorable HPV positive patients (!), and (c) minimizing the side effects of systemic treatment for favorable HPV-positive patients.
