About this trial
Marginal zone lymphoma (MZL) is a common type of indolent lymphoma that originates from the marginal zone of lymphoid follicles. This study aims to evaluate targeted therapy based on the prognostic risk stratification of MZL-IPI in newly diagnosed MZL cases requiring systemic treatment, and provides a basis for precision treatment of MZL.
Eligibility criteria
Qualifiers
1. Histopathologically confirmed CD20-positive marginal zone lymphoma (according to the 2016 WHO classification).
Helicobacter pylori (HP)-positive or HP - negative gastric mucosa extranodal marginal zone lymphoma (MALT) patients with progression/relapse after local treatment (including surgery, radiotherapy, and anti - Helicobacter pylori treatment).
Non - gastric MALT patients with Ann Arbor stage I - II who have progression/relapse after local treatment (including surgery, radiotherapy, etc.), or untreated patients with Ann Arbor stage III - IV who meet the GELF criteria recommended by the NCCN guidelines.
Splenic marginal zone lymphoma (SMZL) patients with progression/relapse after local treatment (including splenectomy, antiviral treatment for HCV - positive patients, etc.), or untreated patients meeting the criteria of progressive or painful splenomegaly, symptomatic or progressive cytopenia such as HB < 100g/L, PLT < 80×10⁹/L, absolute neutrophil count (ANC) < 1.0×10⁹/L.
Disqualifiers
1. Histologically transformed into high-grade lymphoma. 2. Known central nervous system involvement of MZL. 3. Previous systemic treatment including immunotherapy, chemotherapy or targeted drugs.
