以下是引用mingfuyu在2009-6-3 10:42:00的发言: These are malignant glands. What to call depends on where they are. They could be severe dysplasia/carcinoma in-situ. If they invades lamina propria, they are intramucosal carcinoma. If they invades into submucosa, they are invasive adenocarcinoma. |
以下是引用njwbhuang在2009-6-4 20:33:00的发言:
不太同意Dr mingfuyu的观点。此例个人认识是绒毛管状腺瘤伴高度异型增生。虽然部分腺体呈筛状融合,但未见到粘膜肌层的侵犯。现在对结直肠腺癌的诊断标准是肿瘤必须侵犯粘膜下层。以下为WHO关于结直肠癌的定义:Only tumours that have penetrated through muscularis mucosae into submucosa are considered malignant at this site. 即仅有肿瘤穿透粘膜肌层进入到粘膜下层才能称为恶性。 |
