Clinical Staging for Carcinoma of the Cervix with Microinvasive Cancer

Abstract

Classification is fundamental to the quantitative study of any phenomenon. Uniform definitions and systems of classification are prerequisites in the advancement of scientific knowledge. The objectives of classification are for planning of the treatment, prognosis, evaluation of the treatment, continuing investigation of cancer. The definition of microinvasive carcinoma of the cervix is controversial but at this present time , FIGO has classified as stage IA1 and IA2. Stage IA1 is defined as minimal microscopically evidence stromal invasion. Stage IA2 is the lesions which are detected microscopically but can be measured. The upper limit should not show a depth of invasion of more than 5 mm or the horizintal spread not exceed 7 mm ; with or without vascular or lymphatic invasion. However , this definition is not clear for the planning of treatment or prognosis. This is to be discussed.
