Ce este cancerul de prostată? Prostate Cancer—Patient Version. The higher the grade and the stage, the poorer the prognosis. The prostate is part of Cancer prostata def tra male reproductive system that helps make and store seminal fluid. Resources for News Media. Childhood Cancer Genomics.
Radical retropubic prostatectomy is the most commonly used open surgical technique. Transurethral resection of the prostate is the standard surgical treatment for benign enlargement of the prostate. The procedure is done under spinal anesthesia, a resectoscope is inserted inside the penis and the extra prostatic tissue is cut to clear the way for the urine to pass.
The two main complications encountered after prostatectomy and prostate radiotherapy are erectile dysfunction and urinary incontinence , mainly stress-type. Most men regain continence within 6 to 12 months after the operation, so doctors usually wait at least one year before resorting to invasive treatments.
Stress urinary incontinence usually happens after prostate surgery or radiation therapy due to factors that include damage to the urethral sphincter or surrounding tissue and nerves. The prostate surrounds the urethra, a muscular tube that closes the urinary bladder. Any of the mentioned reasons can lead to incompetent closure of the urethra and hence incontinence. More invasive surgical treatment can include the insertion of a urethral sling or an artificial urinary sphincter , which is a mechanical device that mimics the function of the urethral sphincter, and is activated manually by the patient through a switch implanted in the scrotum.
The latter is considered the gold standard in patients with moderate or severe stress urinary incontinence.
Erectile dysfunction happens in different degrees in nearly all men who undergo prostate cancer treatment, including radiotherapy or surgery; however, within one year, most of them will notice improvement. If nerves were damaged, this progress may not take place. Pharmacological treatment includes PDE-5 inhibitors such as viagra or cialis , or injectable intracavernous drugs injected directly into the penis prostaglandin E1 and vasoactive drug mixtures. Other nonpharmacological therapy includes vacuum constriction devices and penile implants.
Many prostate cancers are not destined to be lethal, and most men will ultimately not die as a result of the disease. Mortality varies widely across geography and other elements. In patients who undergo treatment, the most important clinical prognostic indicators of disease outcome are the stage, pretherapy PSA level, and Gleason score.
The higher the grade and the stage, the poorer the prognosis. Nomograms can be used to calculate the estimated risk of the individual patient.
The predictions are based on the experience of large groups of patients. After remission, an androgen-independent phenotype typically emerges, wherein the median overall survival is 23—37 months from the time of initiation of androgen ablation therapy. Several tools are available to help predict outcomes, such as pathologic stage and recurrence after surgery or radiation therapy. Life expectancy projections are averages for an entire male population, and many medical and lifestyle factors modify these numbers. For example, studies have shown that a year-old man will lose 3. If he is both overweight and a smoker, he will lose 6.
No evidence shows that either surgery or beam radiation has an advantage over the other in this regard. The lower death rates reported with surgery appear to occur because surgery is more likely to be offered to younger men with less severe cancers.
Insufficient information is available to determine whether seed radiation extends life more readily than the other treatments, but data so far do not suggest that it does.
Men with low-grade disease Gleason 2—4 were unlikely to die of prostate cancer within 15 years of diagnosis. Men with high-grade disease Gleason 8—10 experienced high mortality within 15 years of diagnosis, regardless of their age. Rates vary widely between countries. The average annual incidence rate of prostate cancer between and among Chinese men in the United States was 15 times higher than that of their counterparts living in Shanghai and Tianjin,    but these high rates may be affected by higher rates of detection. Prostate cancer is the third-leading cause of cancer death in men, exceeded by lung cancer and colorectal cancer. Cases ranged from an estimated , in  to an estimated , In Deaths held steady around 30, in  and 29, in Age-adjusted incidence rates increased steadily from through , with particularly dramatic increases associated with the spread of PSA screening in the late s, later followed by a fall in incidence.
Declines in mortality rates in certain jurisdictions may reflect the interaction of PSA screening and improved treatment. The estimated lifetime risk is about Prostate cancer is more common in the African American population than the White American population. Prostate cancer is the third-leading type of cancer in Canadian men.
In , around 4, died and 21, men were diagnosed with prostate cancer. In Europe in , it was the third-most diagnosed cancer after breast and colorectal cancers at , cases. In the United Kingdom, it is the second-most common cause of cancer death after lung cancer, where around 35, cases are diagnosed every year, of which around 10, are fatal. The prostate was first described by Venetian anatomist Niccolò Massa in , and illustrated by Flemish anatomist Andreas Vesalius in The first treatments were surgeries to relieve urinary obstruction.
Removal of the gland was first described in ,  and radical perineal prostatectomy was first performed in by Hugh H. Young at Johns Hopkins Hospital.
Surgical removal of the testes orchiectomy to treat prostate cancer was first performed in the s, with limited success. Transurethral resection of the prostate TURP replaced radical prostatectomy for symptomatic relief of obstruction in the middle of the 20th century because it could better preserve penile erectile function. Radical retropubic prostatectomy was developed in by Patrick Walsh. In , Charles B. Huggins published studies in which he used estrogen to oppose testosterone production in men with metastatic prostate cancer. GnRH receptor agonists, such as leuprorelin and goserelin , were subsequently developed and used to treat prostate cancer.
Radiation therapy for prostate cancer was first developed in the early 20th century and initially consisted of intraprostatic radium implants. External beam radiotherapy became more popular as stronger [X-ray] radiation sources became available in the middle of the 20th century.
Brachytherapy with implanted seeds for prostate cancer was first described in Systemic chemotherapy for prostate cancer was first studied in the s. The initial regimen of cyclophosphamide and 5-fluorouracil was quickly joined by regimens using other systemic chemotherapy drugs. People with prostate cancer generally encounter significant disparities in awareness, funding, media coverage, and research—and therefore, inferior treatment and poorer outcomes—compared to other cancers of equal prevalence.
Waiting time between referral and diagnosis was two weeks for breast cancer but three months for prostate cancer. A report by the U. The Times also noted an „anti-male bias in cancer funding” with a four-to-one discrepancy in the United Kingdom by both the government and by cancer charities such as Cancer Research UK. Disparities extend into detection, with governments failing to fund or mandate prostate cancer screening while fully supporting breast cancer programs.
For example, a report found 49 U. Prostate cancer experiences significantly less media coverage than other, equally prevalent cancers, outcovered 2. Prostate Cancer Awareness Month takes place in September in a number of countries. A light blue ribbon is used to promote the cause. Enzalutamide is a nonsteroidal antiandrogen NSAA. Alpharadin uses bone targeted Radium isotopes to kill cancer cells by alpha radiation. AR belongs to the steroid nuclear receptor family.
Development of the prostate is dependent on androgen signaling mediated through AR, and AR is also important for disease progression. Molecules that could successfully target alternative domains have emerged. Arachidonate 5-lipoxygenase has been identified as playing a significant role in the survival of prostate cancer cells. Galectin-3 is another potential target. The PIM kinase family is another potential target for selective inhibition. A number of related drugs are under development. It has been suggested the most promising approach may be to co-target this family with other pathways including PI3K.
Scientists have established prostate cancer cell lines to investigate disease progression.
The LNCaP cancer cell line was established from a human lymph node metastatic lesion of prostatic adenocarcinoma. PC-3 and DU cells were established from human prostatic adenocarcinoma metastatic to bone and to brain, respectively. Elevation of AR expression is often observed in advanced prostate tumors in patients. These androgen -independent LNCaP cells have elevated AR expression and express prostate specific antigen upon androgen treatment. Paradoxically, androgens inhibit the proliferation of these androgen-independent prostate cancer cells.
One active research area and non-clinically applied investigations involves non-invasive methods of tumor detection. A molecular test that detects the presence of cell-associated PCA3 mRNA in fluid obtained from the prostate and first-void urine sample is under investigation.
PCA3 mRNA is expressed almost exclusively by prostate cells and has been shown to be highly over-expressed in prostate cancer cells.
The higher the expression of PCA3 in the sample, the greater the likelihood of a positive biopsy. From Wikipedia, the free encyclopedia. Redirected from Cancer prostatae.

There are many connections between the prostatic venous plexus and the vertebral veins. The veins forming the prostatic plexus do not contain valves and it is thought that straining to urinate causes prostatic venous blood to flow in a reverse direction and enter the vertebral veins carrying malignant cells to the vertebral column.
