Abstract

The adoptive transfer of cytotoxic T lymphocytes (CTLs) stimulated by specific tumor antigen peptide‑pulsed dendritic cells (DCs) is one of the most promising immunotherapeutic strategies currently available for patients with gastric cancer (GC). The present case report describes a patient with chemotherapy‑resistant stage IV GC with multiple bone metastases, who had been treated with antigen peptide‑pulsed DC‑CTLs. DCs and CTLs were transfused into the patient subcutaneously and intravenously with simultaneous oral administration of low‑dose cyclophosphamide. Following 3 cycles of combination therapy, marked remission regarding the number of metastatic bone lesions was achieved, confirmed by the use of enhanced computerized tomography, computerized tomography and magnetic resonance imaging. After 1 year, 8 cycles of adoptive immunotherapy were administered, and a further decrease in the number of metastatic bone lesions was observed in addition to a marked improvement in the patient's quality of life. Therefore, personalized antigen peptide‑pulsed DC‑CTLs combined with oral administration of low‑dose cyclophosphamide may serve as a promising anticancer therapy to eradicate tumor cells, and therefore this approach is recommended for future cases of a similar nature.
