What are the prostate cancer clinical symptoms
The incidence of prostate cancer main site for the posterior subcapsular glands. So the general to advanced prostate cancer before symptoms show. A period of clinical disease and often asymptomatic period B, C of obstruction symptoms appear, and D of both distant metastases have symptoms of obstructive symptoms. Common symptoms of the following three groups:
(1) obstruction symptoms: prostate cancer and bladder neck obstruction symptoms of benign prostatic hyperplasia almost no difference, for the performance of the slow flow, urgency, urinary flow interruption, not urination, frequency, can cause serious drops Lek urination and urinary retention . Its obstruction in the course of two clinical significance: ① course of continuous progress, and benign prostatic hyperplasia at the slow progress in different conditions. ② hematuria not common. It is worth noting that prostate cancer is not usually the first symptoms of urethral obstruction, it is the more common local-proliferation and bone metastases symptoms. In the late, only violations of cancer around the urethral obstruction caused symptoms glands.
(2) transfer of symptoms: When the tumor and its violations of the capsule near the nerve around the lymphatic, may appear perineal pain and sciatica. Bone pain is a common symptoms of D, lumbosacral and pelvis for the performance of the continuing pain, bedridden, more intense; rectal involvement can be expressed as bowel problems or colonic obstruction; adenocarcinoma of the current out of the film when the urethra can occur Urinary incontinence; other symptoms of a transfer of lower extremity edema, swollen lymph nodes, subcutaneous nodules transfer, such as pathological fracture.(3) systemic symptoms: systemic symptoms as weight loss fatigue, fever, anemia, the evil of disease or renal failure.
Prostate cancer surgery in the following ways:
(1) transurethral resection: transurethral resection (TUR) is to reduce obstruction of the best I bladder surgery, the period of C lesions TUR only to ease symptoms and improve the patient’s quality of life, but the cure meaningless.
(2) radical prostatectomy: Surgical mainly used in A 2 B period and the period of prostate cancer patients, some patients, radical surgery means that the prostate cancer cure. However, clinical suitable for radical prostatectomy patients rarely, patients are often at the time of diagnosis has missed the best time for surgery. The surgery means there perineum prostatectomy and the suprapubic prostatectomy after two.
(3) expansion of the radical prostatectomy: refers to extensive local tumor resection, and pay attention to the basement with bladder, seminal vesicle and the remnants of the vas deferens, urinary bladder and reproductive after the fascia at. But this surgery often can not obtain the expected results.
(4) resection of the prostate and bladder pelvic clean-up: major expansion of the bladder that radical resection of the prostate and urinary diversion and pelvic organs for radical resection, this destructive surgery, surgical complications and high mortality, it is only used strictly Choice of young people. Its value to be further explored.
Prostate cancer patients should make the following conventional X-ray examination:
(1) intravenous urography inspection: to learn on the urinary tract, and can provide clues to the spread of the bladder neck.
(2) chest and bone X-ray: is to determine the cancer stage. Pulmonary lung can be found on the transfer, often for lymphatic proliferation, nodular rare. The bone metastasis of prostate cancer is a typical signs of osteoarthritis of performance, bone loss, and sometimes also osteolytic changes, any bone may have been violated, the early transfer of the most common site is the lumbar spine and pelvis, followed by the thoracic spine, ribs and Femur.
(3) bladder and urethra contrast: urethra can be observed after the cancer has violations. Angiography showed that the normal curve disappear urethra, urethral rigid and narrow; violations of the bladder, bladder irregular visible at the bottom of the filling defect.
(4) seminal vesicle contrast: prostate cancer can understand the extent of violations of seminal vesicle, but rarely used in clinical.
(5) lymphatic contrast: lymphatic contrast to speculate lymphatic metastasis of prostate cancer, prognosis and treatment are important, even for those without distant metastasis, the invasion of small, low stage prostate cancer lesions, will also show Obvious violation of lymph nodes. However, due to the false positive lymph imaging and false negative more accurate low. Therefore, the current clinical application of less.
