ARS AUC, locoregionally recurrent rectal cancer: R0 resection drives survival/LC; preop chemo/RT + reirradiation endorsed to enable resection, no practice change.
Quiet day: one lower-GI consensus document. The new ARS appropriate-use criteria reaffirm R0 (margin-negative) resection as the determinant of survival and local control, with preop chemo/RT and reirradiation endorsed to downsize toward resectability. Consensus-driven (76 of 116 refs retrospective, only 10 RCTs); reaffirms combined-modality practice rather than changing it.

- ARS Appropriate Use Criteria: Locoregionally Recurrent Rectal CancerR0 (margin-negative) resection drives survival and local control; preop chemo/RT and reirradiation aid downsizing; consensus advises no major practice change.
- PRIMARY2PSMA-PET avoided biopsy in 49% while staying non-inferior for csPCa detection (12% vs 16%) vs systematic biopsy in high-risk equivocal-MRI men.
- INDIBLADE2-yr bladder-intact EFS 78% (0.67-0.9), OS 96% (0.91-1) after induction ipi+nivo then chemoRT in cT2-4aN0-2 MIBC.
- DOREMY5yr local recurrence-free survival 97.4% with reduced 36 Gy preop RT in myxoid liposarcoma; mature long-term dose de-escalation data.
- REVELUTIONAdjusted 12-mo total coronary plaque volume rose 68.9 mm³ more with leuprolide vs relugolix in men on pelvic RT + ADT.
- KEYNOTE-689 vs NIVOPOSTOPTwo positive phase III IO trials in resectable LA-HNSCC: perioperative pembro (EFS+) vs postoperative nivo (3yr DFS ~63 vs 53%), both layered on surgery+adjuvant CRT.
- GEC-ESTRO APBI Patient Selection Guidelines (2026 update)2026 update expands APBI eligibility to pTis/T1-2 ≤30mm, pN0/pN1mi, all histologies; contraindicated for BRCA, age <40, TNBC, EIC+, or extensive LVI.
- EAU 2026: MDT/SBRT Intensification in Oligometastatic Prostate Cancer (Fonteyne)review: MDT/SBRT delays progression and defers systemic Tx in oligomet HSPC; ARTO is the first RCT hinting at an OS benefit.
- NRG Oncology/RTOG 0848Adjuvant chemoRT did not improve OS overall (HR 0.96, p=0.38); node-negative subgroup gained OS (5yr 48.1% vs 28.6%).
- RAPCHEM (BOOG 2010-03)10-yr LRR 2.9% overall with response-adapted RT de-escalation post-NAC; low across all risk strata.
