What are the symptoms of prostate cancer?
A patient with early prostate cancer may have symptoms of:
- A frequent need to urinate, especially at night
- Difficulty in starting or stopping the urine stream
- A weak or interrupted urine stream
- Loss of control of urination with coughing or laughing
- Inability to urinate when standing, requiring sitting during urination
- Pain with urination or ejaculation
- Blood in the urine or in the semen
Many symptoms of early cancer of the prostate can also be attributed to benign (noncancerous) conditions of the prostate including benign prostatic hypertrophy (BPH), or infection in the prostate gland or urinary system.
Symptoms of advanced prostate cancer that has already spread from the prostate gland to elsewhere in the body (called metastatic prostate cancer) include:
- A new dull, then progressively severe, pain in the bones, especially the low back
- Unexplained weight loss
- Increasing shortness of breath while doing activities previously well tolerated
It is always best to find and diagnose prostate cancer at an early stage and hopefully still confined to its site of origin. At that point treatments can cure it. When prostate cancer is widespread or metastatic it can be treated, but it cannot be cured.
What are the stages of prostate cancer?
The term “to stage” a cancer means to describe the evident extent of the cancer in the body at the time that the cancer is first diagnosed. The stage of a cancer helps doctors understand the extent of the cancer and plan cancer treatment. Results of the treatment of similar Gleason score prostate cancer found at the same or similar stage can help the doctor and patient to make important decisions about choices of treatment to recommend or to accept.
Cancer staging is first described using what is called a TNM system. The “T” refers to a description of the size or extent of the primary, or original, tumor. “N” describes the presence or absence of, and extent of spread of the cancer to lymph nodes that may be nearby or further from the original tumor. “M” describes the presence or absence of metastases -- usually distant areas elsewhere in the body other than regional (nearby) lymph nodes to which the cancer has spread. Cancers with specific TNM characteristics are then grouped into stages, and the stages are then assigned Roman numerals with the numerals used in increasing order as the extent of the cancer being staged increases or the cancer prognosis worsens. Prognosis is finally reflected by considering the patient's PSA score at presentation as well as their Gleason score in assigning a final stage designation.
The American Joint Commission on Cancer (AJCC) system for prostate cancer staging is:
T designations refer to the characteristics of the prostate cancer primary tumor.
T1 prostate cancers cannot be seen on imaging tests or felt on examination. They may be found incidentally when surgery is done on the prostate for a problem presumed to be benign, or on needle biopsy for an elevated PSA.
- T1a means that the cancer cells comprise less than 5% of the tissue removed.
- T1b means that cancer cells comprise more than 5% of the tissue removed.
- T1c means that the tissue containing cancer was obtained by needle biopsy for an elevated PSA.
T2 prostate cancers are those which can felt (palpated) on physical examination of the prostate gland (on digital rectal exam) or which can be visualized with imaging studies such as ultrasound, X-ray, or related studies. The prostate gland is comprised of two halves or lobes. The extent of involvement of those lobes is described here.
- T2a means the cancer has grown into less than half of one lobe of the prostate.
- T2b means the cancer has grown more than half of one lobe, but does not involve the other lobe of the prostate.
- T2c means that the cancer has grown into or involves both lobes of the prostate.
T3 prostate cancers have grown sufficiently to extend outside of the prostate gland. Adjacent tissues including the capsule around the prostate gland, the seminal vesicles, as well as the bladder neck may be involved in T3 tumors.
- T3a means that the cancer has extended outside of the prostate gland but not into the seminal vesicles.
- T3b means that the cancer has invaded into the seminal vesicles.
T4 prostate cancers have spread outside of the prostate gland and have invaded adjacent tissues or organs. This may be determined by examination, biopsy, or imaging studies. T4 prostate cancer may involve the external sphincter or valve of the bladder, the bladder itself, the rectum, or the levator muscles or the pelvic wall. T4 tumors have become fixed to or invaded adjacent structures other than the seminal vesicles.
N designations refer to the presence or absence of prostate cancer in nearby lymph nodes including what are referred to as the hypogastric, obturator, internal and external iliac, and sacral nodes.
- N0 means that there is no prostate cancer evident in the nearby nodes.
- N1 means that there is evidence of prostate cancer in the nearby nodes.
- NX means that the lymph nodes cannot or have not been assessed.
M refers to the presence or absence of prostate cancer cells in distant lymph nodes or other organs. Prostate cancer that has spread through the bloodstream most often first spreads into the bones, then into the lungs and liver.
- M0 means that there is no evidence of spread of prostate cancer into distant tissues or organs.
- M1a means that there is spread of prostate cancer into distant lymph nodes.
- M1b means that there is evidence that prostate cancer has spread into bones.
- M1c means that prostate cancer has spread into other distant organs in addition to or instead of into the bones.
