The proposed study is a prospective, single-center, single-arm and open-ended phase II study in patients over the age of 18 with previously untreated mantle cell lymphoma(MCL). The primary objective of this study is to explore the safety and efficacy of a new chemo-free treatment pattern zanubrutinib-rituximab(ZR) in newly diagnosed MCL.

The study will start with an initial 28-days of induction immunotherapy with ZR and 4 cycles of consolidation immunotherapy with ZR，following imaging examinations to evaluate response rates. Patients who are evaluated as SD and PD will be withdrawn from the trial,while those who achieve PR and CR will be further stratified according to their age and physical status. The older or frail patients who are ineligible for ASCT will take zanubrutinib orally until intolerable toxicity or disease progression. Patients who are young and fit for transplantation will receive ASCT consolidation. After ASCT, patients with CR will end therapy and enter the follow-up stage, while patients with PR will continue to take zanubrutinib orally until intolerable toxicity or disease progression.

Inclusion Criteria:

6. Patients must have measurable disease (i.e., ≥ 1.0 cm in lymph nodes diameter; or skin lesions assessed by physical examination);
7. Written informed consent obtained from the subject.

Exclusion Criteria:

1. Indolent Mantle Cell Lymphoma;
