What the trial is, and whether it could suit you
According to inclusion and exclusion criteria, 20 eligible subjects with triple-negative breast cancer (TNBC) scheduled to receive sacituzumab govitecan were screened. Relevant examination results within 2 weeks before enrollment, including blood and urine routine tests, blood biochemistry, electrocardiogram, serum pregnancy test (for females only), imaging examinations, vital signs, and physical examinations, were collected as baseline assessments to determine whether subjects met enrollment requirements. After enrollment, subjects underwent 89Zr-DFO-hSR7 and 18F-FDG examinations at three time points: before sacituzumab govitecan treatment, after 2 cycles of treatment, and at disease progression. (Subjects first underwent 18F-FDG examination, followed by 89Zr-DFO-hSR7 examination within 1 week.) Within 2 years (with a 1-month window) after completing baseline examinations, investigators
