The lack of a uniform, specific definition of microinvasive carcinoma of the cervix has made it difficult to extract from the literature a sufficient number of cases similarly defined from which to estimate the risk of nodal metastasis or death from tumor. Factors potentially biasing the frequency of nodal metastasis and death from tumor are examined, and series lacking such factors are used to provide estimates of the risk of metastasis or death from tumor for various specific definitions, but the number of cases fitting each definition are too few at present to give reliable estimates.
由于缺乏宫颈微浸润癌统一、明确的定义，难以从文献中提取足够数量定义相似的病例，用以评估淋巴结转移风险或肿瘤致死风险。本文研究了可能影响肿瘤淋巴结转移频率和致死率的因素，并采用不包含此类因素的病例系列来估算各种具体定义下肿瘤转移或致死的风险。但目前符合各定义的病例数量过少，无法给出可靠的评估结果。
