FCR/BR→ ibrutinib✖️3months→FCR/BR→ ibrutinib✖️3months→FCR/BR→Maintenance therapy

Induction treatment:

Patients \<65 y and without significant comorbidities are given FCR 1or 2 courses (If patients' white blood cell count \<10×10\^9/L after first course, the second course can be saved). Then, patients takes ibrutinib orally for 3 months alternating with FCR in 2 cylcles.

1. FCR： F（Fludarabine）：25mg/m2·d，d1-3； C（Cyclophosphamide）：CTX 250mg /m2·d，d1-3； R（Rituximab）：375mg/m2 d0（first course），500mg/m2 d0（subsequent courses）；
2. Ibrutinib:420mg/d

FCR and Ibrutinib

Induction treatment:

Patients ≥65y and ≤75 y or \<65 y but with comorbidities, are given BR 1or 2 courses (If patients' white blood cell count drop to below10×10\^9/Lafter first course, the second course can be saved). Then, patients takes ibrutinib orally for 3 months alternating with BR in 2 cylcles. 1.BR： B（Bendamustine）：90mg/m2·d，d1-2； R（Rituximab）：375mg/m2 d0（first course），500mg/m2 d0（subsequent courses）； 2. Ibrutinib: 420mg/d

BR and Ibrutinib

Maintenance treatment:

After induction treatment, recommend ( but not mandatory) Ibrutinib or thalidomide monotherapy(according to patients preferrance) for MRD-positive patients.For MRD-negative patients, recommend ( but not mandatory) no maintenance therapy.
