Abstract
OBJECTIVE
To investigate the clinical characteristics, prognostic factors, and treatment outcomes of patients with limited-stage (Ann Arbor stage I or II) mantle cell lymphoma (MCL).
METHODS
Examining consecutive the clinical characteristics, treatment outcomes and prognostic factors of 47 patients with stage I or II MCL diagnosed in Affiliated Tumor Hospital of Guangxi Medical University from January 2005 to June 2020 were analyzed retrospectively.
RESULTS
The median age of patients was 62(37-78) years old. 36 patients were male, accounting for 76.6% of the whole. Among these, 74.5% (n=35) of the diagnoses were estimated at II stage. According to Mantle cell lymphoma International Prognostic Index (MIPI), 28 patients (59.6%) were classified as low risk. Patients who received first-line treatment and could be evaluated received rituximab combined chemotherapy, chemotherapy alone, cytarabine containing chemotherapy or chemotherapy combined with local radiotherapy, the different first-line therapies did not affect the complete response (CR) rate of patients (P>0.05). The median follow-up time was 81.5 months, the 5-year progression-free survival (PFS) was 37.4% and the 5-year overall survival (OS) rate was 80.6%. Multivariate analysis showed that Ki-67>30% (P<0.05) the independent adverse prognostic factor for PFS and OS.
CONCLUSION
Limited-stage MCL is rare. Patients with limited-stage MCL had a better outcome than those with III-IV stage MCL. Patients with limited-stage MCL whose Ki-67≤30% had better PFS and OS.
