上消化道多原发癌的诊断对决定治疗方案颇为重要,而X线检查是其重要的诊断手段之一,但报道较少,且漏诊和误诊率高。现将经手术病理证实的12例报道如下,并着重对其X线诊断及漏诊、误诊原因进行回顾性分析,以便引起工作中的注意。1 临床资料 1970～1987年我院胸外科共手术治疗食管、贲门癌510例,经手术病理证实的上消化道多原发癌12例,占2.4％,均为双原发癌。其诊断标准基本以Warren及Gate提出的多原发癌诊断标准,即①每个肿瘤必须证实为恶性肿瘤;②肿瘤之间必须分别清楚;③必须明确每一个肿
The diagnosis of multiple primary cancers of the upper digestive tract is very important in determining the treatment plan, and X-ray examination is one of its important diagnostic methods, but reports are few, and the rate of missed diagnosis and misdiagnosis is high. The 12 cases reported by surgery and pathology are now reported as follows, and their X-ray diagnosis, missed diagnosis, and misdiagnosis are analyzed retrospectively to bring attention to the work. 1 Clinical data From 1970 to 1987, the thoracic surgery in our hospital treated 510 patients with esophageal and cardiac cancers. The primary pathologically confirmed multi-primary cancer was 12 cases, accounting for 2.4%, all of which were double primary cancers. The diagnostic criteria are basically based on the diagnostic criteria of multiple primary cancers proposed by Warren and Gate, that is, each tumor must be confirmed as a malignant tumor; 2 tumors must be clearly separated; 3 must be clear for each tumor
