Cancer staging - Systems of staging

The stage of a cancer is a descriptor (usually numbers I to IV) of how much the cancer has spread. The stage often takes into account the size of a tumor, how deep it has penetrated, whether it has invaded adjacent organs, if and how many lymph nodes it has metastasized to, and whether it has spread to distant organs. Staging of cancer is important because the stage at diagnosis is the biggest predictor of survival, and treatments are often changed based on the stage.

Staging systems are specific for each type of cancer (e.g. breast cancer and lung cancer). Some cancers, however, don't have a staging system. Often competing staging sytems exist for the same type of cancer; however, the universally-accepted staging system is that of the UICC, which has merged its staging system with that of the AJCC.

Overall Stage Grouping is also referred to as Roman Numeral Staging. This system uses numerals I,II,III, and IV to describe the progression of cancer. Stage I cancers are localized to one part of the body. Stage II cancers are locally advanced, as are Stage III cancers. Whether a cancer is designated as Stage II or Stage III can depend on the specific type of cancer; for example, in Hodgkin's Disease, Stage II indicates affected lymph nodes on only one side of the diaphragm, whereas Stage III indica ...

Cancer staging can be divided into a clinical stage and a pathologic stage. In the TNM (Tumor, Node, Metastasis) sytem, clinical stage and pathologic stage are denoted by a small 'c' or 'p' before the stage, e.g. cT3N1M0 or pT2N0. Clinical stage is based on all of the available information obtained before a surgery to remove the tumor. Thus, it may include information about the tumor obtained by physical examination, radiologic examination, and endoscopy. Pathologic stage adds additional information ...
