20 posts held, back to 6 August 2026 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 page of Telegram’s post history, 20 posts per page.
Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 20 posts for this entry, the most recent from 8 August 2026. An engagement rate over an empty window would be a number about nothing.
In cervical cancer treated with radiotherapy, response was 88% with low CAVIN3 expression versus 57% with high expression. In a separate 66-patient cohort, median progression-free survival was 59.9 vs 9.8 months. #RadOnc #CervicalCancer #Biomarker Full summary: https://radonctoday.com/low-cavin3-expression-was-associated-with-better-radiotherapy-response-in-cervical-cancer/
In surgically treated head and neck cutaneous squamous-cell carcinoma, perineural invasion was associated with an ~80% higher risk of death when radiotherapy was omitted. Among patients who received radiotherapy, that survival disadvantage was no longer evident - an important signal, but still observational evidence. #RadOnc #SkinCancer #HeadAndNeck Full summary: https://radonctoday.com/radiotherapy-may-offset-the-…
In newly diagnosed glioblastoma, shortening chemoradiation from 30×2 Gy over 6 weeks to 6×6 Gy over 2 weeks reduced median survival from 21 to 13 months and increased radiation necrosis/pseudoprogression from 16% to 48%. This regimen should not replace standard chemoradiation. #RadOnc #Glioblastoma Full summary: https://radonctoday.com/six-fraction-chemoradiation-worsened-survival-in-newly-diagnosed-glioblastoma/
In RAPIDO, TNT doubled complete response from 14.3% to 28.4% and reduced distant failure, but 5-year local recurrence was higher. For organ preservation, OPRA favors chemoradiation followed by consolidation chemotherapy. #RadOnc #RectalCancer #Chemoradiotherapy Full summary: https://radonctoday.com/total-neoadjuvant-therapy-is-now-central-to-high-risk-rectal-cancer-and-organ-preservation/
Median cerebellar dose was 4.3 Gy, yet no brain region showed a significant dose-cognition link through 12 months after head and neck RT. Reassuring, but only 24 patients completed one-year testing. #RadOnc #HeadAndNeckCancer #LateEffects Full summary: https://radonctoday.com/low-incidental-brain-doses-were-not-linked-to-early-cognitive-decline-after-head-and-neck-radiotherapy/
Three-year survival was 50.2% with extratumoral versus 57.9% with intratumoral PNI after oral cavity treatment. ENE extent did not separate outcomes, making PNI location the more interesting risk signal. #RadOnc #OralCancer Full summary: https://radonctoday.com/extratumoral-perineural-invasion-predicted-worse-outcomes-after-postoperative-oral-cavity-radiotherapy/
One RT study highlighted in this review used 15,724 cases and raised modality-selection accuracy from 50% to 71%. The bigger issue now is safe deployment: hallucinations, bias, privacy and regulation remain unresolved. #RadOnc #AI #MedicalPhysics Full summary: https://radonctoday.com/generative-ai-is-spreading-across-radiation-therapy-workflows-but-validation-remains-the-bottleneck/
In simulated half-detector CBCT with dental metal, PSNR rose from 25.5 to 35.5 dB and SSIM from 0.71 to 0.94. Strong artifact reduction, but no clinical scans were tested. #RadOnc #CBCT #AI Full summary: https://radonctoday.com/deep-learning-reduced-combined-truncation-and-metal-artifacts-in-half-detector-cbct/
Across 198 prostate SBRT patients and six MRIs each, rectal spacer shape stayed essentially stable for about a month. Only a tiny shift toward a rounder shape was detected, without meaningful rectal dose changes. #RadOnc #ProstateCancer #SBRT #MRgRT Full summary: https://radonctoday.com/rectal-spacer-geometry-remained-stable-throughout-five-fraction-prostate-sbrt/
Synthetic CT changed target doses by only fractions of a Gy and produced submillimetre translational tracking errors. Rotational matching was less stable, with several outliers above 5°. #RadOnc #BrainMetastases #CyberKnife #SyntheticCT Full summary: https://radonctoday.com/mr-only-cyberknife-planning-achieved-near-equivalent-dosimetry-for-brain-metastases/
Applicator reconstruction error fell to 0.1 mm, while bladder and rectal artifact burden dropped by about half. Contouring was 30–40% faster, but needle artifacts remained harder to correct. #RadOnc #Brachytherapy #CervicalCancer #AI Full summary: https://radonctoday.com/task-specific-deep-learning-reduced-ct-metal-artifacts-in-cervical-brachytherapy/
53.6% developed grade ≥2 esophagitis. A three-variable model using tumor location, hypertension and albumin reached an AUC of 0.816, while more complex machine-learning models did no better. #RadOnc #EsophagealCancer #Toxicity Full summary: https://radonctoday.com/three-clinical-variables-predicted-moderate-to-severe-esophagitis-during-esophageal-cancer-radiotherapy/
Showing the 12 most recent of 20 posts we hold for @radonctoday. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.

Channels on the register that have forwarded this channel's posts into their own feed.
Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.
A live page changes as we take new readings, so a citation should name the measurement it is based on, not just the URL. The line below cites the subscriber count as measured 17 September 2026 — this entry's latest reading, not the date you are reading this.
