本综述旨在对子宫颈早期浸润癌的生态学方面的概念予以更新。子宫颈微浸癌(MICA)是原位癌(CIS)向临床浸润癌发展的过渡时期。这种早期浸润指出病变的重要性。虽然也可自行愈合,但它是病变进展的客观证据,而浸润是恶性的最重要指标。微浸癌患者之平均年龄比原位癌较大。有人报告原位癌诊断时平均年龄为41岁,微浸癌为46岁,浸润癌为52岁。微浸癌最小年龄为23岁,也可见于较大年龄。其流行病学资料如产次、初婚年龄、多次结婚等与原位癌及浸润癌相似,而无特殊临床发现,若临床诊断出则不属I_A期。发病率:在假定原位癌行子宫颈锥切或子宫切除标本中,微浸癌只占3～8%。有人报告在某大学
This review aims to update the ecological aspects of early invasive carcinoma of the cervix. Cervical microencapsulated carcinoma (MICA) is a transitional period from the development of carcinoma in situ (CIS) to clinical invasive carcinoma. This early infiltration indicates the importance of the lesion. Although it can also be self-healing, but it is objective evidence of the progress of the disease, and infiltration is the most important indicator of malignancy. The average age of patients with micro-invasive carcinoma is larger than that of carcinoma in situ. It was reported that the average age at diagnosis of carcinoma in situ was 41 years, the micro-invasive cancer was 46 years old and the invasive cancer was 52 years old. The minimum age of micro-cancer is 23 years old, also seen in older age. Its epidemiological data such as parity, first marriage age, multiple marriages and carcinoma in situ and invasive carcinoma similar, but no special clinical findings, if the clinical diagnosis is not I_A period. Incidence: In situ hypodermic hypothyroidism or hysterectomy specimens, micro-invasive cancer accounted for only 3 to 8%. Someone reported at a college
