International Federation of Gynecology and Obstetrics (FIGO) stage according to 2009 definitions. Data on patients affected by Stage 0 disease is not collected. Stage I: the carcinoma is strictly confined to the cervix (extension to the corpus would be disregarded). Stage IA: invasive carcinoma that can be diagnosed only by microscopy, with deepest invasion less than or equal to 5 mm and largest extension less than or equal to 7 mm. CODE 1 Stage IA1 Measured stromal invasion of less than or equal to 3.0 mm in depth and extension of less than or equal to 7.0 mm. CODE 2 Stage IA2 Measured stromal invasion of greater than 3.0 mm and less than 5.0 mm with an extension of not more than 7.0 mm. Stage IB: clinically visible lesions limited to the cervix uteri or preclinical cancers greater than stage IA. CODE 3 Stage IB1 Clinically visible lesion less than or equal to 4.0 cm in greatest dimension. CODE 4 Stage IB2 Clinically visible lesion greater than 4.0 cm in greatest dimension. Stage II: cervical carcinoma invades beyond the uterus, but not to the pelvic wall or to the lower third of the vagina. Stage IIA: without parametrial invasion. CODE 5 Stage IIA1 Clinically visible lesion less than or equal to 4.0 cm in greatest dimension. CODE 6 Stage IIA2 Clinically visible lesion greater than 4.0 cm in greatest dimension. CODE 7 Stage IIB With obvious parametrial invasion. Stage III: the tumour extends to the pelvic wall and/or involves lower third of the vagina and/or causes hydronephrosis or non-functioning kidney. CODE 8 Stage IIIA Tumour involves lower third of the vagina, with no extension to the pelvic wall. CODE 9 Stage IIIB Extension to the pelvic wall and/or hydronephrosis or non-functioning kidney. Stage IV: the carcinoma has extended beyond the true pelvis or has involved (biopsy proven) the mucosa of the bladder or rectum. A bullous oedema, as such, does not permit a case to be allotted to Stage IV. CODE 10 Stage IVA Spread of the growth to adjacent organs. CODE 11 Stage IVB Spread to distant organs. |
