近年来,临床对多原发癌(Multiple primarycancer)的诊断,已引起人们广泛注意;本组发现6例,现将治疗体会报道如下,并结合文献加以讨论。 多原发癌近年来有些报道,其发生率约在10％左右,McNeer等曾统计了1,685例原发性胃恶性肿瘤,其中23例为多原发性胃恶性肿瘤,可见临床并非少见,而在文献中早期癌发现甚少,张荫昌等发现最常见是进行期癌,伴另一个早期癌灶,大体形态表现,称作主癌和副癌;本文6例中,有三例为胃贲门及胃内早期癌,实属罕见;其中二例为术前确诊。见(附表)。 In recent years, clinical diagnosis of multiple primary cancers has attracted widespread attention; 6 patients were found in this group and treatment experience is reported as follows and discussed in combination with literature. Many primary cancers have been reported in recent years, the incidence of which is about 10%. McNeer et al. had statistics on 1,685 primary gastric malignancies, of which 23 were multi-primary gastric malignancies. In the literature, very few early cancers were found. Zhang Yinchang et al. found that the most common stage was staged cancer, with another early stage cancer, gross morphological manifestations, known as primary and secondary cancers; of the 6 cases, there were three cases of gastric cardia and stomach. Early cancer is rare; two of them were diagnosed before surgery. See Schedule).
