An Overview Of Prostate Cancer Staging

By Nancy Gardner


Staging of cancer is meant to help the medical practitioner to tell how far it has spread. You will have to go through a series of scans and tests to determine the extent of the pathology. From the results, effective treatment plans can then be put into action. Prostate cancer staging is therefore very important.

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.

Stage two in the tumor classification system is divided into three. T2a means half of the prostate gland is affected while in T2b the area affected exceed half. In T3c, the whole of the gland has been invaded by the cancerous cells. In tumor stage 3, the capsule has been broken into by the cancerous cells. This stage also has been subdivided into T3a where the capsule is the only other place which has been affected besides the prostate gland and in T3b, seminal vesicles have been invaded by the cancerous cells.

The final stage in tumor classification is T4 stage in which the tumor is found in various body organs. The nearby organs are mostly affected including the rectum, muscles, bladder and the pelvic cavity sides. The fourth and third stages are the most difficult to manage.

In lymph node staging, the guiding factor is the severity of the condition in the lymph nodes. They are said to be positive if they contain cancer cells. This makes them to swell. In NX stage, it is not possible to check them and in N0 stage the lymph nodes adjacent to the prostate have no cancer cells. However, in N1 stage, the malignancy has reached the lymph nodes.

When classifying according to the degree of spread, the first stage is M0 which signifies that the tumor is confined just within the pelvis. In M1, the cancer has finally got out of the pelvis. It has sub stages. The first one is the M1a where the lymph nodes next to the pelvis have been affected and M1b means the skeletal system has been affected by the tumor. In M1c, the malignancy has eventually spread to the rest of a body. A couple of factors are considered in doing the staging.

Locally advanced type of prostate cancer extends just to the capsule of this gland but the metastasizing type spreads to many of body organs. Mainly, the victims of this spread are the bones and lymph nodes. This is why early detection is stressed to prevent such complications.

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.
