Objective To evaluate clinical application of VCS technology in diagnosis for acute leukemia and its subtypes by LH750 automated hematology analyzer. Methods A total of 178 leukemia patients (105 acute granilocytic leukemia, 42 acute lymphocytic leukemia, 31 acute monecytic leukemia)and 151 non-leukemia patients (86 granulocytic abnormal cases, 35 lymphocytic abnormal cases,30 monocytic abnormal cases) were enrolled into this study. Peripheral blood samples were analyzed by both Coulter LH750 automated hematology analyzer and manual microscopic examination. Microscopic examination was used as reference to evaluate the diagnosis value of VCS technology in blast detecting. VCS parameters were compared for AGL subsets. The clinical value of VCS technology in diagnosis for different acute leukemia was also evaluated by combining VCS scattergram and suspect flags provided by LH750. Results Compared with manual examination, a sensitivity of 95.5% (170/178) and specificity of 95.4% (144/151) were achieved by VCS technology in detecting blasts in acute leukemia and nonleukemia patients. In patients with AGL, the MNV, MNV-SD, MNC and MNC-SD (224.40 ± 23.37,37.40 ±12. 31,145. 80 ±7. 93,24. 79 ±5. 18) were higher than granulocytic abnormal patients( 169.96 ±11.50,29.21 ± 5.27,133.30 ± 5.50, 10.62 ± 4.09) and the differences were statistically significant ( t values were 16. 832, 5. 148, 5. 735, 19. 953 respectively, P < 0. 01 ). On the contrary, MNS ( 122. 90 ±6. 35) in AGL patients was significantly lower than granulocytic abnormal patients( 131.00 ± 5. 69, t =-7.64, P<0.01). In patients with ALL, the MLV, MLV-SD, MLC, MLS, MLS-SD (97.60 ± 13.40,22. 35 ± 7.94,110. 00 ± 4. 60,77. 60 ± 19.00,20. 61 ± 3.30 ) were higher than lymphocytic abnormal patients(82. 10 ± 3.00, 14.41 ±2.35, 100.60 ±2.70, 48. 10 ±3.50, 17.60 ± 1.60). The data also showed a statistical significance (t values were 7.576, 6. 118, 4. 041, 9. 353, 2. 988 respectively, P <0.05). In patients with AMOL, the MMV, MMV-SD, MMC, MMC-SD, MMS(197. 30 ±20.50,30.47 ±6.58,123.20 ± 10. 10,6.57 ± 1.57,98.00 ± 5.60) were significantly higher than monocytic abnormal patients( 167.80 ± 15.77,21.90 ± 9. 64,113.60 ± 6. 73,5.20 ± 3. 21,84. 20 ± 14. 35 ) and the differences were statistically significant (t values were 6. 332, 4. 033, 4. 650, 2. 993, 6. 273 respectively , P <0. 01 ).The differences of MNV, MNV-SD, MNC, MNC-SD, MNS-SD for different AGL subtypes were statistically significant ( F values were 21.2, 169. 5, 13.6, 3. 6 and 98.6 respectively, P <0. 01 ). For AGL, ALL and AMOL, the ratios of normal blast distribution in scattergram were 81% (85/105), 74% (31/42) ,and 74% (23/31).
