The study includes 7 stages: ① screening period; ② tissue collection; ③ TILs cell production and preparation; ④ lymphocyte depletion pretreatment; ⑤ TILs cell infusion; ⑥ safety and efficacy evaluation; ⑦ follow-up.

Enrollment: 15 estimated patients

Sex: All

Ages: 18 to 70 years old

Volunteers: No Healthy Volunteers
