FAP-targeted PET/CT imaging in patients with breast cancer from a prospective bi-center study: insights into diagnosis and clinic management.
Eur J Nucl Med Mol Imaging
January 2025
Department of Nuclear Medicine and Minnan PET Center, Xiamen Key Laboratory of Radiopharmaceuticals, The First Affiliated Hospital of Xiamen University, School of Medicine, Xiamen University, Xiamen, China.
Purpose: To evaluate the diagnostic accuracy and clinical impact of fibroblast activation protein (FAP)-targeted PET/CT imaging in primary and metastatic breast cancer and compare the results with those of standard-of-care imaging (SCI) and [F]FDG PET/CT.
Methods: We prospectively analyzed patients with diagnosed or suspected breast cancer who underwent concomitant FAP-targeted PET/CT (radiotracers including either [Ga]Ga-FAPI-46 or [F]FAPI-42) and [F]FDG PET/CT scans from June 2020 to January 2024 at two medical centers. Breast ultrasound (US) imaging was performed in all treatment-naïve patients as SCI.
Factors Affecting the Prognosis after Primary Tumor Resection for Patients with Metastatic Colorectal Cancer with Synchronous Peritoneal Metastasis: A Multi-center, Prospective, Observational Study.
J Anus Rectum Colon
January 2025
Division of Molecular and Diagnostic Pathology, Niigata University, Graduate School of Medical and Dental Sciences, Niigata, Japan.
Objectives: To clarify the risk factors affecting prognosis after primary tumor resection (PTR) in patients with metastatic colorectal cancer with synchronous peritoneal metastasis (mCRC-SPM).
Methods: Patients were enrolled prospectively in the JSCCR project "Grading of Peritoneal Seeding in Colorectal Cancer." Factors that may influence overall survival-age, sex, location of the primary tumor, lymph node metastasis, presence of liver metastasis, degree of peritoneal metastasis, peritoneal cancer index (PCI), cancer cure, and postoperative chemotherapy-in the PTR group were examined using multivariate analysis.
Radiomics-based Machine Learning Approach to Predict Chemotherapy Responses in Colorectal Liver Metastases.
J Anus Rectum Colon
January 2025
Department of Gastroenterological Surgery, Graduate School of Medical Sciences, Kumamoto University, Kumamoto, Japan.
Objectives: This study explored the clinical utility of CT radiomics-driven machine learning as a predictive marker for chemotherapy response in colorectal liver metastasis (CRLM) patients.
Methods: We included 150 CRLM patients who underwent first-line doublet chemotherapy, dividing them into a training cohort (n=112) and a test cohort (n=38). We manually delineated three-dimensional tumor volumes, selecting the largest liver metastasis for measurement, using pretreatment portal-phase CT images and extracted 107 radiomics features.
Outcome of Lu-DOTATATE Peptide Receptor Radionuclide Therapy in Progressive Metastatic Neuroendocrine Tumors from a Tertiary Care Center.
Indian J Endocrinol Metab
December 2024
Department of Nuclear Medicine, Christian Medical College, Vellore, Tamil Nadu, India.
Introduction: Functioning neuroendocrine tumors (NETs) that do not respond to standard therapies are commonly considered for Peptide Receptor Radionuclide Therapy (PRRT). The benefit of Lu-DOTATATE PRRT in patients with progressive metastatic NET was analyzed and survival in multi-organ involvement.
Methods: Forty-one patients with refractory, progressive, or advanced symptomatic NETs, with or without previous treatment modalities were studied.

Aim: To define the indications and outcomes of intraoperative ablation of hepatic malignancies.
Materials And Methods: This retrospective study comprises 27 patients (male/female: 19/8; mean age: 56 ± 13) undergoing intraoperative ablation (IOA) of liver tumours between July 2001 and August 2021 for 42 tumours, including colorectal liver metastasis (CRLM) (n = 27), hepatocellular carcinoma (HCC)(n = 14), and ovarian cancer metastasis (n = 1). The mean tumour diameter was 2.
