Gamma delta T-cell infusion plus chemotherapy induces long-term remission of gastric cancer after immunochemotherapy failure: A case report

Figure 1 Endoscopic and histopathological findings. A: Esophagogastroduodenoscopy reveals an ulcerative lesion in the gastric antrum; B: Hematoxylin and eosin staining of the biopsy specimen shows moderately differentiated adenocarcinoma with poorly differentiated components (original magnification × 200).

Figure 2 Radiologic response to combination therapy. A and B: Contrast-enhanced abdominal computed tomography (CT) performed before initiation of ramucirumab plus trifluridine/tipiracil combined with gamma delta T-cell infusion demonstrates a 2.1 cm hepatic metastatic lesion and enlarged para-aortic lymph nodes; C and D: Follow-up CT obtained after four months of therapy demonstrates disappearance of the hepatic lesion and marked regression of lymphadenopathy (A and C: Transverse plane; B and D: Coronal plane).
