Abstract:
Objective To investigate the relationship between coagulation function and the tumor size, clinical stage and metastasis status in renal cell carcinoma (RCC) patients. Methods A total of 290 RCC patients from 2004 to 2009 were included in present study. There were 181 male patients and 109 female patients. The average ages was (56.3± 13. 5) years. There were 252 cases of clear cell carcinoma, 19 cases of papillary carcinoma, 5 cases of chromophobe cell carcinoma, 3 cases of cystic RCC, and 11 cases of other types. TNM classification: stage Ⅰ 202 patients, stage Ⅱ32 patients , stage Ⅲ 32 cases, stage Ⅳ 24 cases. There were N0 264 patients, N1 11 patients and N2 15 cases. There were M0 273 cases, M1 17 cases. One hundred and eighty-six cases of benign renal tumors were set as the control group. Fibrinogen (Fib), prothrombin time (PT), activated partial thromboplastin time (APTT) and international normalized ratio (INR) were detected. Results The preoperative serum Fib of RCC patients was (39. 6±15.6) g/L, the control group was (32. 8±8. 2)g/L. There was significant difference between them (P<0. 05). The values of preoperative APTT,INR, and PT were (31.7±5.2)s, (1.0±0. 1), (11.2±1.3)s in RCC group and (32. 4±4.2)s,(1.0±0. 1), (11.1±1.3)s in the control group. There were no significant differences between them (P＜0.05). The values of Fib in stage Ⅰa, Ⅰb, Ⅱ, Ⅲ, Ⅳ groups were (32. 6±6. 6), (36. 1±8. 7),(48.8±21.6), (49.9± 17.8) and (59.7± 19.2)g/L, respectively. There was no significant difference between stage Ⅰ, and the control group. But the other stages showed significant difference with the control group (P<0.01). Hyperfibrinogenemia (Fib>44.0 g/L) in the RCC group accounted for 74 cases (25.5%). If the value of Fib ≤44. 0 g/L, 92.1% of patients can be excluded from the probability of metastasis. Conclusions Preoperative plasma Fib levels could be elevated in RCC patients with distant metastasis or lymph node metastasis. Increased preoperative plasma Fib levels, especially hyperfibrinogenemia may be a predictor of metastasis.
