病灶明显局限的原发性乳腺癌患者治疗前进行病期估计的检查选择尚存争议。本文研究了在这些病例处理中应用CT检查转移病灶的价值。 对1988年8月至1991年10月117例病灶明显局限的乳腺癌患者的检查结果进行回顾性分析。采用Siemens Somaton DRH扫描仪对决定作乳腺手术的患者在3个月内作头、胸、腹及盆腔CT检查,以动态模型和静脉对比造影从脑至耻骨联合进行断层,并对骨、肺和软组织窗进行评估。报告由5位高级放射学专家中任一位作为日常工作的一部分发出。所有病例均作血细胞计数,部分病例作了肝功能、胸片、骨扫描以及肝脏超声检查。大多数病例属早期(T_138例,T_251例,T_316例,T_412例),淋巴结受累随T分期成比例增加。随访6～42月(中位期20日)。结果发现,仅4％的病例经CT检查到转移病灶(T(1～2)期病例中,仅1％检查出,1/
It is controversial that the choice of screening for disease estimates for primary breast cancer patients before treatment is clearly limited. This article examines the value of using CT to detect metastatic lesions in these cases. The retrospective analysis of the results of 117 cases of breast cancer with limited lesions from August 1988 to October 1991 was performed. Head, chest, abdomen, and pelvic CT scans were performed within 3 months of the patients who decided to undergo breast surgery using a Siemens Somaton DRH scanner, and a dynamic model and vein contrast angiography were performed to segment the brain from the brain to the pubic symphysis. Soft tissue windows are evaluated. The report was issued by any of the five senior radiology specialists as part of their daily work. Blood cell counts were performed in all cases, and liver function, chest radiographs, bone scans, and liver ultrasonography were performed in some cases. Most of the cases were early (T_138 cases, T_251 cases, T_316 cases, T_412 cases), and lymph node involvement increased proportionally with T stage. Follow-up was from 6 to 42 months (median 20 days). The results showed that only 4% of cases were metastatic lesions detected by CT (only 1% of T(1～2) cases were detected, 1/
