PET predicts chemotherapy responses in breast cancer patients

PET/CT with gallium-68 FAPI radiotracer can predict responses to neoadjuvant chemotherapy in breast cancer patients.

November 8, 2023

Representative Ga-68 FAPI-PET/CT images of 48-year-old woman who had left invasive ductal carcinoma and who achieved pathologic complete response (pCR). (A) Baseline maximum-intensity projection (MIP) image demonstrated primary lesion (red arrowhead; SUVmax, 26.72) and Ga-68 FAPI-avid lymph node in left axilla (red arrows). (B) MIP image after two cycles of neoadjuvant chemotherapy (NAC) showed that primary lesion (red arrowhead; SUVmax, 8.87) and axillary lymph nodes (red arrow) were reduced in size and radioactivity uptake. (C and D) Representative images of lab tissue staining for FAP before NAC showed strong FAP-positive staining in stromal cells (C), which was significantly decreased on tumor bed after six cycles of NAC (D).

FAPI-PET bests FDG-PET in detecting gastrointestinal cancer

Fibroblast activation protein inhibitor (FAPI)-PET/CT appears superior to standard FDG-PET/CT for detecting gastrointestinal cancer.

October 31, 2023

Nine representative patients who underwent F-18 FDG and F-18 FAPI-74 PET imaging. F-18 FAPI-74 PET outperforms F-18 FDG-PET in detecting primary tumors (patients 11, 39, 50, 58, 79, and 101; solid black arrows), local recurrences (patient 4; blue arrows), abdomen LN metastases (patients 4 and 50; green arrows), intrahepatic metastases (patient 50; red arrows), bone metastases (patient 85; arrowheads), and peritoneal metastases (patients 4, 11, 85, 97, and 101; dotted arrows).
