A female patient was diagnosed as gastric cancer (T4aN2M0). CT before neoadjuvant chemotherapy (a) showed a mass-type tumor measured 25 mm in maximal depth and 80 mm in maximal length. CT after neoadjuvant chemotherapy (b) showed a shrunken mass measured 14 mm in depth and 40 mm in length. CT before neoadjuvant chemotherapy (c) showed the ROI delineated manually on figure (a). Pathology examination after surgery (d) showed residual tumor tissue (arrow) and infiltrated inflammatory cells (arrow head)
