Objective:
To explore the relationship of clinic features, lab findings, the origin of tumor cell as well as prognosis in Chinese patients with diffuse large B-cell lymphoma( DLBCL).
Methods:
Seventy four cases of primarily diagnosed DLBCL were analyzed. Immunohistochemistry stain was used to check the expressions of Bcl-6,CD10 and MUM1.
Results:
Among the 74 patients, the average age was 58.5 years, the ratio of male to female was 1.64:1. 23.2% (16/69) cases developed in lymph node, 15.9% (11/ 69) in the extra node area. Among 55 follow-up cases, 13 (23.6%) died, and 12 (92.3%) died in the first year after diagnosis. The prognosis analysis showed that diagnosed at age > 65 years (P = 0.036), and the international prognostic index (IPI) (P = 0.009) were independent prognostic factors; origin of tumor cell had a trend to be a prognostic factor, but no statistic difference (P = 0.086). beta2-MG and Bcl-6 expression had no relation with the prognosis.
Conclusion:
The middle and old-aged male patients are the most common in DLBCL and the first-year mortality rate is higher. The age at diagnosis and IPI can predict the clinical outcome. The origin of tumor cell might suggest the prognosis.
