Description:

In this trial, the patients will receive multiple high-activity γδ T cell immunotherapies.The trial is divided into two parts: Part 1 is a multiple-dose escalation trial consisting of 3 dose groups (2×10\^8 cells/person, 5×10\^8 cells/person, 10×10\^8 cells/person at 1-3 infusion, 4-6 infusion and 7-9 infusion), with 9 patients planned to be enrolled. Part 2 is a single dose trial in which doctor and the PI evaluates whether to give the rest patients to receive the 10×10\^8 cells/person infusions based on available safety data. The check indexes are CT scan，intestinal flora detection and blood tests (including tumor markers, lymphocyte subsets and circulating tumor cell).
