CT scan evaluations before and after treatment. CT scans performed 18 weeks before ICI treatment (first column), at baseline (second column) and for early evaluation eighteen days after the beginning of ICI treatment (third column) show the changes in lymph nodes and hepatic lesions: the left para-aortic lymph node (red arrow, line A) increased from 30mm at baseline to 40mm on day 18, known hepatic lesion increased (red arrow, line B), multiple new hepatic lesions appeared and locoregional invasion led to gastric stump compression.
