新生血管形成被认为是肿瘤发生的重要表现,许多资料表明血管密度能反映肿瘤的临床行为。为证实彩色多普勒超声检测肿瘤血管情况的临床意义,研究了65例肿瘤可见的Ⅰb期至Ⅱb期宫颈癌患者,患者平均年龄50.2岁(32～68岁),Ⅰb期48例(占73.8％);Ⅱ期17例(占26.2％);鳞癌61例(占93.8％);腺癌4例(占6.2％)。全部患者均在宫颈癌根治术加盆腔淋巴结清扫术前1～2天行经阴彩色多普勒检测肿瘤内及子宫动脉血流,计算动脉阻力指数(RI)。检测到肿瘤内血流者30例定为检测组,另35例未检测到者定为对照组。通过碘染法及
Neovascularization is considered to be an important manifestation of tumorigenesis. Many data indicate that the vascular density reflects the clinical behavior of the tumor. To confirm the clinical significance of color Doppler ultrasonography in the detection of tumor vessels, we studied 65 cases of stage Ⅰb to Ⅱb cervical cancer with mean age of 50.2 years (32-68 years), stage Ⅰb of 48 cases (73.8% 17 cases (26.2%) in stage Ⅱ, 61 cases of squamous cell carcinoma (93.8%) and 4 cases of adenocarcinoma (6.2%). All patients underwent intracranial color Doppler flow cytometry of intracranial and uterine artery 1 to 2 days prior to radical mastectomy plus pelvic lymphadenectomy to calculate the arterial resistance index (RI). Tumor blood flow detected in 30 cases as the test group, the other 35 cases were not detected as the control group. By iodine staining method
