Aspects Taken Into Account During Prostate Cancer Staging

By Nancy Gardner


Staging of tumors helps the doctor to tell how extensive the disease is. However, several scans have to be done and tests carried out for a proper diagnosis. From the results, management plans can then be drawn. This is why professionals in the medical field emphasize on prostate cancer staging.

The TNM staging system is the commonly accepted technique of staging prostate cancer. It assesses metastases, lymph nodes and tumor separately. T staging comes first. In tumor stage 1, the malignancy cells are so insignificant such that they cannot be picked up by scans or the normal laboratory tests. A needle biopsy has to be done for confirmation purposes.

Tumors in stage T2 are classified into three categories. The first one is T2a which indicates that only one lobe of the prostate gland is affected. In T2b, more than half of gland is affected and in T2c stage the entire lobe is affected. On the other hand, if the tumor has left the prostate gland to affect the capsule but has not spread further is said to be in stage T3. This stage has two categories. T3a and T3b where the malignancy has reached the capsule and seminal vesicles respectively.

Stage T4 tumors usually have metastasized. The common areas affected include the pelvic cavity, bladder and rectum. The T4 and T3 tumor stages are said to be locally advanced stages. These are the most difficult stages to treat.

Lymph nodes are said to be positive if they have been invaded by cancer cells. They will increase in size during this time. In stage NX, the lymph lodes have not been affected. In N0, the lymph node close to the prostate gland have no cancer cells but in N1 stage, the lymph nodes close to the gland have been affected

In metastasis staging, the first one is Mo where the malignancy has not spread out of pelvis. In M1, the malignancy has reached outside the pelvis. This stage has three subdivisions. In M1a, the cancerous cells have not affected the lymph nodes which are not in the pelvis while in M1b, the malignancy has spread to the bone. Last come M1c in which the cancer has spread to the rest of body organs. There are different things which have to be put into consideration when staging the cancer. Mostly, it is the invasiveness of the disease and its aggressiveness.

The cancer is said to be locally advanced if it has proceeded beyond the capsule. If it said to have metastasized, it means that it has reached the rest of body organs. The areas which are affected the most by cancer proceeding from the prostate gland are the bones and the lymphatic organs.

Metastasis can occur when the tumor is still in its initial stages. That is why people are advised to regularly go for blood tests and scans for early diagnosis. If some cancerous cells are found in other body organs, immediate action should be taken to control the spread.
