An Overview Of 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 internationally accepted staging criteria takes into account the lymph node, metastasis and tumor factors . T1 stage tumors are very small such that they cannot be detected through scans or the techniques used in physical examination. You can only confirm the diagnosis by asking the patient to do a needle biopsy.

T2 stage tumors are inside the prostate gland only. They are in three groups. The initial one is T2a where just half of gland lobes are affected. In T2b, more than half of the gland has been affected and lastly in T2c, all of lobes have been affected. If the malignancy has spread to the capsule of the gland, it is classified as T3 tumor.

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.

The lymph nodes will be described to be positive if they have cancerous cells. This makes them enlarge. The degree of enlargement is directly proportional to the number of cancer cells in the lymph node. In NX stage, the nodes can not be checked while in N0 stage, the nodes close to the gland have not been affected. In N1 stage, the lymph nodes have cancerous cells.

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 cancer of the prostate is confined to the gland but the metastatic type has spread. The places which are hardly hit are the bones and lymph nodes. However, many a times it reaches other body organs too.

To note is that it is possible for the malignancy to spread even when it not advanced. This is why serious actions should be taken to manage the disease in case scans show that there is some degree of metastasis. The cure rates are high if the treatment is started early.
