• Patients received no prior anti-lymphoma treatment;
• At least one evaluable lesion according to 2014 Lugano criteria;
• Ann Arbor stage II-IV;
• Eastern Cooperative Oncology Group (ECOG) of 0-2;
• Life expectancy > 3 months;
• Able to participate in all required study procedures;
• Proper functioning of the major organs: 1) The absolute value of neutrophils (>1.5×10^9/L); 2) platelet count (> 75×10^9/L); 3) Hemoglobin (> 80 g/L); 4) Serum creatinine <1.5 times Upper Limit Normal (ULN) ; 5) Serum total bilirubin < 1.5 times ULN; 6) Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT) < 2.5 times ULN; 7) Coagulation function: International Normalized Ratio (INR), Prothrombin Time (PT), Activated Partial Thromboplastin Time (APTT) < 1.5 times ULN (unless the subject is receiving anticoagulant therapy and PT and APTT are within the expected range at screening time);

Exclusion Criteria:

• Involvement of central nervous system (CNS)
