在最常见的死亡病因中,胰腺癌在男性列第四位,在女位列第五位,80%为起源于导管的腺癌,5年生存率低于5%.近年来报道了一种预后好得多的胰腺恶性肿瘤,命名为“实质和乳头状”或“乳头状囊性”瘤,在外科文献上尚未见报道,作者在本文中报告二例,并收集到文献中迄今报告的60例.大多数胰腺实质和乳头状肿瘤发生于年轻女性病人,平均年龄24岁,主诉为逐渐增大的腹部肿块,全身健康情况良好.大多数肿瘤位于胰腺尾部,细胞呈实质或乳头状排列,囊性退化变较常见.在有些病例肿瘤细胞延伸至邻近实质内,似为局部浸润.对这组病人平均随诊7.1年,只有1例死于远处转移,在 Among the most common cause of death, pancreatic cancer ranks fourth in males and fifth in females, 80% of which are adenocarcinomas originating from ducts. The 5-year survival rate is less than 5%. Pancreatic malignancies with a much better prognosis, named “parenchymal and papillary” or “papillary cystic” tumors, have not been reported in surgical literature. The authors reported two cases in this article and collected the literature. In the 60 cases reported so far, the majority of pancreatic parenchyma and papillary tumors occurred in young female patients, with an average age of 24 years. The complainant complained of a gradually increasing abdominal mass and good general health. Most of the tumors were located in the tail of the pancreas. Or papillary arrangement, cystic degeneration becomes more common. In some cases, tumor cells extend into the adjacent parenchyma, appearing to be local infiltration. The average follow-up of this group of patients was 7.1 years, and only 1 case died of distant metastasis.
