title: [Clinical analysis of the character and prognostic factors of 23 cases of mantle cell lymphoma].
abstract: OBJECTIVE
  To investigate the clinical characteristics and prognostic factors of mantle cell lymphoma (MCL) patients.
  
  
  METHODS
  The clinical data of 23 MCL patients were retrospectively analyzed. Immunohistochemical stain was performed to detect the protein expressions of Mcl-1, pNF-κB p65 and 14-3-3ζ of MCL patients to analyze its prognostic factors.
  
  
  RESULTS
  Among 23 MCL patients, there were 17(73.9%) patients with IPI 0-2 (low risk group) and 6(26.1%) patients with IPI 3-4. Only the rate of 2y-progression-free survival (PFS) of group IPI 0-2 was superior to that of group IPI 3-4 patients (47.1% vs 0, P=0.049); There were 16 (69.5%) patients with MIPI < 5.7, whose rates of overall response rate (ORR), 2y overall survival (OS) and PFS were better than those of the ones with MIPI ≥ 5.7(ORR: 81.3% vs 33.3% P=0.032; OS: 68.8% vs 16.7% P=0.041; PFS: 50% vs 0, P=0.040 respectively). The rates of ORR, 2y-OS and 2y-PFS (100.0%, 80.0% and 70.0%) of patienets received regimen R+CHOP(E) were all superior to those (38.5%, 30.8% and 7.7%) of ones received regimen CHOP(E) (P=0.002, P= 0.024, P=0.003, respectively). Among 12 patients, 2 out of 6 cases with Mcl-1 positive expression achieved good response (CR+PR) and 2y-OS, 1 case 2y-PFS; All 6 cases with Mcl-1 negative expression achieved good response (CR+PR) and 2y-OS, 5 cases 2y-PFS. 3 out of 6 cases with pNF-κB p65 positive expression achieved good response (CR+PR) and 2y-OS, 1 case 2y-PFS; 5 out of 6 cases with pNF-κB p65 negative expression achieved good response (CR+ PR) and 2y-OS/PFS. 5 out of 8 cases with 14-3-3ζ positive expression achieved good response (CR+PR), 4 cases 2y-OS, and 3 cases 2y-PFS. 3 out of 4 cases with 14-3-3ζ negative expression achieved CR, 4 cases 2y-OS, and 3 cases 2y-PFS.
  
  
  CONCLUSIONS
  MCL patients had high heterogeneity. MIPI has better prognostic significance than IPI. R+CHOP(E) as first line treatment improved the rates of OS/PFS. The expressions of Mcl-1, pNF-κB p65 and 14-3-3ζ proteins in MCL might be related to prognosis.
