title: The Prognostic Significance of the Serum p53 Protein Concentration in Chinese Patients with Non-Hodgkin Lymphoma.
abstract: OBJECTIVE
  To investigate the prognostic significance of cytogenetic abnormalities, staging, patient factors, and the serum p53 protein concentration in Chinese non-Hodgkin lymphoma (NHL) patients.
  
  
  METHODS
  The study included 43 patients with NHL that were identified between August 2003 and December 2008. Patient clinical characteristics patients were determined based on morphological, immunohistochemical, and cytogenetic analysis, and the serum p53 protein concentration was measured quantitatively.
  
  
  RESULTS
  Following conventional chemotherapy, the complete/partial remission (CR/PR) rate was significantly higher and overall survival (OS) was significantly longer in the patients with early-stage (stage I-II) lymphoma, normal karyotype, and a low serum p53 protein concentration than in those with advanced-stage (stage III-IV) lymphoma, cytogenetic abnormalities, and a high serum p53 protein concentration (≥0.35 U/mL). Bone marrow infiltration was also a predictor of poor response and OS. There weren't any significant differences in disease remission between the male and female patients, older and younger patients (aged <70 years vs. ≥70 years), or B-cell lymphoma and T-cell lymphoma patients.
  
  
  CONCLUSIONS
  Staging is an effective means of assessing the severity of NHL. Cytogenetic examination can provide useful information for diagnosis, staging, and prognostication. The serum p53 protein level may be a potential prognostic marker in patients with NHL.
