Clinical analysis of acute cerebral infarction accompanied with lung cancer

Objective: To analyze the characteristic of coagulation function in non-small cell lung cancer patients with acute cerebral infarction as the initial symptom. Methods: Cases diagnosed as non-small cell lung cancer in our hospital from January 2015 to January 2016 were used for study. Fifteen cases with acute cerebral infarction as the initial symptom were included in experimental group. Thirty-three cases with no initial symptom on acute cerebral infarction were included in control group. Clinical data in patients of two groups were collected, including general information, coagulation function index, thrombelastogram index. Results: The prothrombin time (PT) [(9.69 ± 1.42) vs. (13.04 ± 1.96) s], activated partial thromboplastin time (APTT) [(30.14 ± 5.79) vs. (39.34 ± 7.63) s], international normalized ratio (INR) [(0.76 ± 0.10) vs. (1.35 ± 0.22)], coagulation reaction time (R) [(4.76 ± 0.79) vs. (6.11 ± 0.93) min], and blood clot formation time (K) [(1.73 ± 0.21) vs. (6.11 ± 0.93) min] in patients of experimental group were obviously lower than that of in control group. Fibrinogen (FIB) [(5.43 ± 0.89) vs. (2.14 ± 0.36) g/L], D-dimer [(0.84 ± 0.17) vs. 0.30 ± 0.06) mg/L], the maximum amplitude of thrombus (MA) [(65.62 ± 10.34) vs. (48.69 ± 8.61) mm], and α-angle [(68.12 ± 9.51) vs. (60.37 ± 10.29) deg] in patients of experimental group were obviously higher than that in control group. PT, APTT, INR, R value, and K value in patients of tumor node metastasis (TNM) Stage III–IV were significantly lower than that in TNM Stage I–II, and FIB, D-dimer, MA, α-angle were all higher than that in patients of TNM Stage I–II. PT, APTT, INR, R value, K value in patients with lymphatic metastasis were significantly lower than that in patients with no lymph node metastasis, and FIB, D-dimer, MA, α-angle were obviously higher than that in patients with no lymph node metastasis. Conclusions: Patients with non-small cell lung cancer have hypercoagulability and hyperfibrinolysis with acute cerebral infarction as the initial symptom, and coagulation function involved in the development of lung disease
