补充资料：癌前病变
癌前病变
癌前病变主要是病理形态学的概念，临床上一般难以明确诊断。癌前病变的组织学特征主要表现为细胞增生和非典型性的出现，称为上皮不典型增生。镜下见底层细胞增生，从1～2层增至多层，甚至占据上皮的大部分，且有细胞排列紊乱，核增大，深染，染色质分布不均等核异质改变。轻度不典型增生细胞的异形性较轻，细胞排列稍紊乱，病变局限在上皮层的1/3，中度不典型增生细胞的异形性明显，细胞排列紊乱，病变局限在上皮层的2/3，重度不典型增生细胞显著异形，极性几乎全消失，病变几乎累及全部上皮层，仅剩1～2层表面的正常鳞状上皮。但是，癌前病变亦远不一定都发展成癌，很多非典型增生是可以恢复正常的，但向前发展成癌的可能性亦不可忽视。一般过程是：增生开始时只是单纯性增生，经过长期、持续增生，并反复接受刺激，遂出现非典型增生，非典型增生的进一步发展才转变为癌。单层立方或柱状上皮的增生主要表现为储备细胞增生，上皮复层化。非典型性表现为核增大、深染、大小不等、核位上移并参差不齐；胞浆内分泌物减少或缺。癌前病变是癌变前必经之病变，但本身并非恶性。
