乳腺粘液癌临床病理分析

The clinical and pathological analysis of the mucinous carcinoma of the breast

作者分析了２９４例乳腺癌手术中８例粘液癌的临床病理特点。粘液癌是临床上少见的特殊组织类型，以粘液产生为特征，分单纯型和混合型，与通常型乳腺癌相比，其淋巴结转移低（２５％），预后良好。分析其原因①粘液对癌浸润形成防御屏障；②癌细胞自身产生的粘液阻碍其代谢。一般对混合型以根治术为原则，单纯型可以考虑缩小手术。

The clinical and the pathological features of eight breast mucinous carcinoma, which had been found from the 294 cases of the breast carcinoma, were analysed. Mucinous carcinoma has its special feature. It can be divided into simple and mixed types. It has a lower lymph metastases rate (25%), and a better prognosis. This might be due to: ① the mucin forms a barrier to the invasion of the cancer cell; ② the mucin production can impede the metabolism of the cancer cell. The radical mastectomy is generally adviced for the mixed type; for the simple type, simpler operation may be ther treatment of choice.
