FIGOklassificeringen

The FIGO classification is a system used to stage gynecological cancers, primarily cervical, uterine, ovarian, and vulvar cancers. FIGO stands for the International Federation of Gynecology and Obstetrics. This classification system is crucial for determining the extent of the disease and guiding treatment decisions.

The FIGO staging system assigns a stage number, typically from I to IV, based on factors such as the size of the tumor, whether it has spread to nearby lymph nodes, and if it has metastasized to distant organs. Higher stage numbers generally indicate more advanced cancer. For cervical cancer, for example, staging considers the depth of invasion and involvement of the vagina, cervix, and surrounding structures.

Over the years, the FIGO staging system has undergone revisions to incorporate new knowledge and improve its accuracy. These updates often include changes in the definitions of stage criteria and the inclusion of new diagnostic information, such as imaging results or pathological findings. The current staging is based on clinical examination and imaging, but surgical staging can also be incorporated.

The FIGO classification is widely used internationally by oncologists, pathologists, and researchers. It facilitates standardized reporting of cancer cases, allows for comparisons of treatment outcomes across different institutions and countries, and is essential for clinical research and the development of new therapies. Accurate staging according to the FIGO system is a fundamental step in the management of gynecological malignancies.
