Clinical stage of prostate cancer

(1) A period of the disease: A phase were completely confined to the prostate, the volume is very small, no symptoms, only occasionally in the investigation when the body was found. No local or distant spread, difficult to detect clinically. Only by autopsy pathology, removal of benign prostatic hyperplasia specimens or biopsy specimens to diagnostic examination. Lesions confined to cell differentiation and a good, relatively slow growth, rectal examination can not be touched nodule diagnosis, clinical disease-free transfer, the period of about 9 percent of prostate cancer. Forward-looking and retrospective studies show that the A period of general good prognosis, most patients do not live long enough to progress to clinical cancer or hidden cancer.

(2) B phase lesions: B phase lesions confined to the prostate capsule, the tumor slightly larger, but has yet to break through the prostate cyst, most of the digital rectal examination detected a single nodule of the prostate, there is no distant metastasis signs. Through prostate biopsy confirmed histological examination. B period in the development of prostate cancer than a short period of time, so fewer cases of clinical findings, accounting for about 11 percent of prostate cancer around.

(3) C diseases: disease beyond the prostate capsule, seminal vesicle adjacent to violations, such as the bladder neck adjacent tissues and organs, but no evidence of distant metastasis. Phase C is not the treatment of prostate cancer is about 60% of exacerbations in patients with 5 years, 10 occurred in the transfer of half of the year, 75% died of prostate cancer. This period accounts for about 44 percent of prostate cancer.

(4) D diseases: disease beyond the prostate, and distant metastasis, distant bone, or even the lung, liver and adrenal metastasis can occur. D patients with poor prognosis, the majority died within 3 years after diagnosis of distant metastasis cancer. This period of about 36%.

Defined the stages of prostate cancer will help to understand the scope of diseases to determine prognosis and to develop treatment programs. For A, B patients, due to lesions confined to the prostate with the basic, you can fight as soon as possible, radical prostatectomy; of C, D phase has been outside and distant metastasis of prostate patients, can only do palliative resection of the prostate, combined with endocrine therapy and radiotherapy and chemotherapy treatment.
