The survival of 28 patients with pancreatic cancer was studied following initial detection of this malignant neoplasm by ultrasonic scanning. By ultrasound examination, 24 patients had an abnormality, and 21 had a demonstrable mass. Twenty-seven patients are now deceased, and the overall survival ranged from eight days to 24 months (mean, 6.1 months). The results of this study indicate that diagnosis by ultrasonic scanning had no effect on the survival of patients with pancreatic carcinoma.
对28例胰腺癌患者在通过超声扫描首次检测到这种恶性肿瘤后的生存情况进行了研究。通过超声检查，24例患者有异常，21例有可显示的肿块。27例患者现已死亡，总体生存期从8天到24个月不等（平均6.1个月）。本研究结果表明，超声扫描诊断对胰腺癌患者的生存没有影响。
