[Relationship between coagulation function and international prognostic index in lymphoma patients].

The study was aimed to investigate the clinical significance of coagulation function changes in lymphoma patients and to analyze the relationship between their changes and international prognostic index (IPI). The prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT) and fibrinogen (FIB) were detected by magnetic bead method in 75 lymphoma patients and 20 healthy persons. The dehydrogenase (LDH) level was detected by rate method in all lymphoma patients and healthy persons. The results showed that (1) the APTT and FIB more obviously increased in lymphoma patients which displayed as hyperfibrinogenemia, as compared with control group (p < 0.05, p < 0.01); no obvious changes of coagulation indexes presented in patients with different ages and extranodal lesions (p > 0.05, p < 0.01). (2) APTT and FIB levels in stage III and IV patients were much higher than those in the stage II (p < 0.05 and < 0.01), and FIB level in stage IV group was significantly higher than those in the stage III (p < 0.05). FIB level in symptomatic group was significantly higher than that in asymptomatic group (p < 0.01). (3) APTT and FIB in increased LDH group were obviously higher than those in control group (p < 0.05, p < 0.01). Furthermore, FIB in increased LDH group was higher than that in normal LDH group (p < 0.05). FIB in performance status (PS) 2 - 4 groups increased significantly as compared with those in PS 0-1 group (p < 0.01). (4)FIB levels in the low-middle-risk, high-middle-risk and high-risk groups were significantly higher than those in control group (p < 0.01), while FIB levels in high-middle-risk and high-risk groups were higher than those in low-risk group (p < 0.05). (5) the number of FIB increased patients in symptomatic group, increased LDH group, PS 2 - 4 group and Ann Arbor stage III-IV group were much higher than those in counterparts (p < 0.05 or 0.01).There were positive correlations between FIB and LDH level, PS grades, Ann Arbor stages as well as risk grades respectively (p < 0.05 or 0.01). It is concluded that lymphoma patients usually accompany with hyperfibrinogenemia which may be influenced by Ann Arbor stage, systemic symptom, LDH level and PS grade. FIB is supposed to be an effective indication of prognosis in lymphoma patients.
