目的探讨上消化道多原发癌的临床X线特点、诊断标准及其发病机理。分析X线误漏诊原因并提出相应解决对策。方法回顾性分析经内镜、手术病理证实的34例上消化道多原发癌的X线资料。结果(1)本病男/女=3.25/1,高龄居多,>50岁者占88%。(2)食管多原发癌中癌灶分布以中、上段居多,占78.8%,食管-胃多原发癌中癌灶分布以食管中、下段、贲门部居多,占72.2%。(3)X线表现与单发癌相同。早期癌占14.5%,进展期癌占85.5%。(4)漏诊率高达32.3%。结论X线检查对上消化道多原发癌具有重要诊断价值。
Objective To investigate the clinical features, diagnostic criteria and pathogenesis of multiple primary cancers in upper gastrointestinal tract. Analyze the causes of X-ray misdiagnosis and propose corresponding solutions. Methods Retrospective analysis of X-ray data of 34 cases of primary primary cancers of the upper digestive tract confirmed by endoscopy and surgical pathology. Results (1) The male / female = 3.25 / 1 of the disease, mostly elderly,> 50 years old accounted for 88%. (2) The majority of esophageal cancer in the distribution of foci in the upper, mostly, accounting for 78.8%, esophageal - gastric multiple primary cancer in the esophagus in the distribution of the lower segment, cardia majority, accounting for 72.2%. (3) X-ray manifestations and single cancer the same. Early cancer accounted for 14.5%, advanced cancer accounted for 85.5%. (4) Misdiagnosis rate as high as 32.3%. Conclusion X-ray examination of the upper gastrointestinal multiple primary cancer has important diagnostic value.
