Complete response to preoperative chemoradiotherapy in highly advanced gastric adenocarcinoma

Figure 4 Resected specimen and histopathological findings. A, B: Macroscopic appearance of the surgically resected stomach. An ulcerative lesion was identified on the lesser curvature of the antrum. No tumor cells were observed in either the primary lesion (C, HE stain, 40×) or the dissected lymph nodes (D, HE stain, 40×), thus confirming a grade 3 effect (pathological complete response, pCR) for the treatment regimen.
