Overview

A prospective collection of data on the treatment of Chinese patients with relapsed/refractory follicular lymphoma (FL) using Axicabtagene Ciloleucel Injection, and evaluation of the efficacy and safety of Axicabtagene Ciloleucel Injection in this treatment.

Eligibility

Inclusion Criteria:

1. Histologically confirmed follicular lymphoma (FL) grade 1, 2, or 3a according to WHO 2016 classification criteria
2. Subjects with relapsed or refractory FL after prior second-line or higher therapy Prior therapy must include: anti-CD20 monoclonal antibody in combination with an alkylating agent (anti-CD20 monoclonal antibody monotherapy is not eligible as a line of therapy for eligibility).

10. Platelet count ≥ 75×10\^9/L
11. Absolute lymphocyte count ≥ 0.1×10\^ 9/L
12.
