Study backs LDCT lung cancer screening in Singapore

July 8, 2026

Response Evaluation Criteria in Bone Metastases (RECIBM) and metabolic criteria were used to detect a complete response missed at anatomic assessment. A 76-year-old male patient presented with 1 month of hemoptysis and was diagnosed with small cell lung cancer and bone metastases. Baseline (July 2022) F-18 FDG-PET/CT images (A, maximum intensity projection image; B–E, axial images) demonstrate FDG-avid lesions in the left lamina of the first lumbar vertebra (L1) (straight yellow arrows; maximum standardized uptake value, 2.74; peak standardized uptake value normalized to lean body mass, 1.59) and left ilium (curved yellow arrows; maximum standardized uptake value, 3.68; peak standardized uptake value normalized to lean body mass, 2.28). After seven chemotherapy cycles (December 2022), follow-up PET/CT images (F, maximum intensity projection image; G–J, axial images) show complete metabolic resolution of bony lesions (L1: maximum standardized uptake value, 1.32, and peak standardized uptake value normalized to lean body mass, 0.85; left ilium: maximum standardized uptake value, 1.48, and peak standardized uptake value normalized to lean body mass, 0.82), without apparent osteolytic or osteoblastic changes at CT. Assessment was stable disease (SD) according to the University of Texas MD Anderson Cancer Center (MDA) criteria but complete response (CR) or complete metabolic response (CMR) according to RECIBM, PET Response Criteria in Solid Tumors (PERCIST), and European Organization for Research and Treatment of Cancer (EORTC) criteria. The patient was alive as of September 30, 2025.

New criteria evaluates treatment response in bone metastases

AR-guided localization may sub for CT for early-stage lung cancer

By Amerigo Allegretto

AR-guided localization was noninferior to conventional CT guidance and led to better patient experiences.

New criteria evaluates treatment response in bone metastases

RECIBM-defined response classifications showed high agreement with established criteria and reclassified 19% of patients.

CT sign may flag who benefits from subdural hematoma procedure

Among participants with the “the hyperdense capsule sign,” middle meningeal artery embolization resulted in significant benefits over usual care.

PET/CT guides treatment in men with recurrent prostate cancer

F-18 fluciclovine and Ga-68 PSMA-11 PET/CT have similar benefits for sRT planning, in terms of improving cancer control without increased toxicity.

June 30, 2026

F-18 fluciclovine PET/CT images in a 59-year-old man with biochemical recurrence after prostatectomy (prostate-specific antigen level, 0.42 ng/mL; Gleason score, 5 + 4 = 9; T3BN1M0). (A) Coronal PET and (B) maximum intensity projection images show multiple retroperitoneal lymph nodes with abnormal radiotracer uptake (arrows). (C) Axial PET and (D) axial fused PET/CT images show the index lesion (arrow), measuring 13 × 10 mm, on the right precaval lymph node. The initial decision to offer radiation therapy to the prostate bed and pelvis was changed to a decision not to offer radiation therapy.
