第十届亚太地区肿瘤会议病理组收到来稿91篇,其中国外来稿9篇,在病理组会议报告13篇,其它均作为墙报(Poster)张贴在会议大厅内。其主要内容摘要如下: 日本学者Itabashi等报告的题目是“影响原发性胃恶性淋巴瘤预后的病理学因素”,作者根据Sano’s对胃恶性淋巴瘤的大体分类,将手术切除的80例原发性胃恶性淋巴瘤分为五型:(1)表浅型;(2)溃疡型;(3)隆起型;(4)凹陷型;(5)巨皱襞型。表浅型相似早期胃癌的Ⅱc,Ⅱc+Ⅱb,Ⅱc+Ⅱa型。研究显示:表浅型与巨皱襞型多局限于粘膜下层以内,无淋巴结受累,组织学常为结节性淋巴瘤,它们比其它类型的淋巴瘤预后较好。相反,隆起型、凹陷型、溃疡型,大体
The 10th Asia Pacific Regional Oncology Pathology Group received 91 submissions, of which 9 were foreign submissions, 13 were reported in the pathology group meeting, and others were posted as posters in the conference hall. The main contents are summarized as follows: Japanese scholar Itabashi et al. reported on the topic of “pathological factors affecting the prognosis of primary gastric malignant lymphoma.” According to Sano’s general classification of gastric malignant lymphoma, 80 cases of surgical resection Gastric malignant lymphomas are divided into five types: (1) superficial; (2) ulcerated; (3) uplifted; (4) depressed; (5) giant crumple type. The superficial type is similar to IIc, IIc+IIb, and IIc+IIa type of early gastric cancer. Studies have shown that superficial and giant folds are mostly confined within the submucosa, no lymph nodes are involved, and histology is often nodular lymphoma. They have a better prognosis than other types of lymphoma. In contrast, uplift, depression, and ulceration, generally
