What is known and objective: Anti-CD19 CAR-T cell therapy is effective in B-cell lymphoma. However, it is rarely used in lymphoma combined with other malignant tumours.
Case description: A relapsed/refractory follicular lymphoma (r/r FL) patient underwent anti-CD19 CAR-T cell therapy and achieved complete response to lymphoma. However, gastric adenocarcinoma (GAC) was diagnosed during the cellular therapy. After infusion of CAR-T cells, he received curative treatment for GAC, and maitained complete response in both r/r FL and GAC after the treatment.
What is new and conclusion: Anti-CD19 CAR-T therapy is an effective treatment for r/r FL, also provided opportunity for the sequential therapy of GAC, and remained significant quality of life afterwards.
Keywords: CAR T cell therapy; case report; follicular lymphoma; gastric adenocarcinoma; multiple primary malignant tumours.
