Surgical Treatment of Prostate Cancer

| from Booking Health GmbH | Diagnosis & treatment

Almost any actively dividing cell of the human body can become a cancer cell. The prostate gland cells are not an exception, as they produce prostate fluid – part of the semen, which protects spermatozoids and guarantees their viability. This disease is widespread and takes the second place among all oncological conditions in men.

Almost any actively dividing cell of the human body can become a cancer cell. The prostate gland cells are not an exception, as they produce prostate fluid – part of the semen, which protects spermatozoids and guarantees their viability. This disease is widespread and takes the second place among all oncological conditions in men. Special attention should be paid to people over 65 years of age, as they account for more than 70 % of all prostate cancer patients.

Good news is that the prostate cancer usually grows slowly and doesn`t affect one’s lifestyle at all. It can be found just by accident during a general examination. Due to this, doctors have multiple choices when making a decision regarding type of prostate cancer treatment.

In certain cases active treatment may be substituted with simply being watchful and waiting for further signs or active surveillance. Under all circumstances, a consulting doctor (general physician), urologist (keen on surgical interventions), radiation oncologist and medical oncologist (keen on chemotherapy and hormone therapy) will give you the information about all appropriate options. To be noted, 5-year relative survival rate after the treatment is close to 100 %.

What determines the type of treatment choice?

Slow growth is a typical feature of prostate cancer, which makes it easier to detect the disease at an earlier stage. Actually, some men with this type of cancer might never need any kind of treatment, especially elderly men or those with other serious health problems.

Another important thing is total absence of symptoms; signs of cancer usually arise only at more advanced stages of the disease. Having regular preventive examinations is a cornerstone of prostate cancer diagnosis and timely treatment.

The first and the most essential aspect of treatment tactics choice is  determining the stage of the disease at the time of diagnosis. Usually the diagnosis starts from preventive screening examination or basic examination due to patient`s complaints.

Primary diagnostic procedures include:

  • Digital rectal examination (DRE). This manipulation enables the doctor to find the tumor mechanically, during assessing prostate via the patient`s rectum.
  • Prostate-specific antigen (PSA) blood test. PSA is produced only by the prostate and its level obviously reflects the state of the gland. Normal level of PSA is no higher than 4 ng/ml; results from 4 to 10 ng/ml reveals a 25 % possibility of cancer presence and result over 10 ng/ml shows a 50 % possibility of having this condition. PSA level is significant for staging, planning further examination and follow-up after radical treatment.

In case suspicious results of DRE and PSA blood test are present, further and more profound examination is administered.

In addition to general analyses, specific diagnostic plan consists of the following investigations:

  • Transrectal ultrasound (TRUS) of the prostate gland
  • Prostate biopsy under the TRUS control (up to 12 samples of tissue are usually taken)
  • Bone scan (to exclude metastases presence)
  • CT / MRI scan (to assess state of nearby organs and exclude metastases in soft tissues)
  • Lymphatic nodes biopsy (if signs of oncological process spreading are present)

The diagnosis of prostate cancer is confirmed or excluded only by biopsy. Beyond all doubt, biopsy results are the basis of future treatment plan.

Besides the normal picture, biopsy may reveal pre-cancerous conditions of the prostate:

  • Prostatic intraepithelial neoplasia (PIN). In PIN prostate cells are slightly changed, but don`t grow into other parts of the gland or to the nearby tissues. PIN might be low-grade; this state has no connection to the oncological process. Revealing high-grade PIN means 20 % opportunity of having cancer in the other area of prostatic gland.
  • Proliferative inflammatory atrophy (PIA). In PIA cells are smaller in size and show signs of inflammatory process. PIA is not dangerous itself, but can progress to high-grade PIN or cancer.
  • Atypical small acinar proliferation (ASAP), or glandular atypia. In ASAP there is certain suspicion for cancer, but the amount of changed cells is not sufficient to make the final conclusion. In this case the best option is repeated biopsy within a few months.

Finding pre-cancerous conditions of the prostate doesn`t obligatory mean that prostate cancer will arise in the future, we are talking about only a possibility and certain risk.

Final diagnosis of cancer is confirmed in case of receiving such results:

  • Adenocarcinoma. This is the most common type of prostate cancer (more than 90 %). Adenocarcinomas develops slowly and there is a chance to postpone active treatment.
  • Small cell carcinoma and neuroendocrine tumors. These types of tumors tend to have a rapid growth and spreads to the lymphatic nodes and inner organs.
  • Transitional cell carcinomas. We are talking about this type of tumor when cells have features of few different neoplasms. Transitional cell carcinomas require active treatment.

The next step to determining treatment tactics is staging the tumor. Comprehensive approach to the assessment of prostate cancer stage includes:

  • Level of the PSA at the time of diagnosis.
  • TNM classification. “T” reflects clinical (detected by DRE) and pathological (based on the results of imaging investigations or surgical treatment) extent of the primary tumor. “N” reflects spreading of the tumor to lymphatic nodes. “M” reflects presence of remote metastases.
  • Grade group. Grade group takes into account the Gleason score and predicts the tumor`s speed of growth and spreading. Gleason score is calculated once biopsy results are ready and  the degree of atypia can be assessed under the microscope. Grade I is given to almost normal cells, grade 5 – to highly abnormal ones. Scores are summed for two the most typical prostate areas. Gleason score under 6 means that the tumor is well differentiated or low-grade, from 6 to 10 – that the tumor is moderately differentiated or intermediate-grade, over 10 – that tumor is poorly differentiated or high-grade. Higher the score is, the quicker the treatment should be started.

Which treatment tactics offer the best results?

In case of symptoms absence, small size of the initial tumor and its slow growth (low Gleason score), low level of PSA and age over 60 years doctor may advise to postpone active treatment.

According to the data of clinical trials, more than 70 % of all patients with prostate cancer will never need to go through surgical intervention, radiation therapy or drug therapy.

In this situation a doctor may offer you two options:

  • Active surveillance. You will visit your general practitioner every 6 months and have PSA blood test and DRE. Biopsy of the prostate will be repeated each year, if necessary. Results of the examination will influence further treatment options.
  • Watchful waiting (observation). This is a type of follow-up with fewer tests; attention therefore is focused at complaints and clinical symptoms.

Opinion of the patient is important as well. Some people may strongly give preference to radical treatment, regardless of its risks and side effects. They have  the right for such a point of view, as active surveillance may give cancer a chance to grow and spread, which restricts possible treatment options. Other people may like the idea of postponing active treatment, because surgery may not help them to live better or they don`t want to face numerous side effects.

Surgical removal of the prostate gland is the only option of radical treatment. Taking into consideration all benefits and risks of such intervention, surgery is recommended in such cases:

  • Good general state of health
  • Estimated expectancy of life over 10 years
  • High risk of cancer progression
  • Localized form of cancer without spreading to lymphatic nodes and other organs
  • No previous radiation therapy

In certain cases prostatectomy may be performed before radiation therapy in order to reduce the volume of the tumor mass and increase the effect of following treatment. Such approach may be somewhat useful even in case of the presence of few metastases.

Radical prostatectomy: open approach

Radical prostatectomy implies total and irreversible removing of prostate gland, seminal vesicles, part of urethra and vas deferens. There are few techniques of this intervention, but the first stage, preparation for surgery, is common.

To make surgery and postoperative period as safe and comfortable, as possible, patients should follow these rules:

  • Visit hospital 5-7 days before the surgery to have preliminary tests done and see related specialists
  • Stop taking certain drugs (warfarin, nonsteroidal anti-inflammatory drugs, etc.) 1-2 weeks before the procedure
  • Lose weight
  • Quit smoking and using other tobacco related products
  • A few days before the surgery take medication to ensure normal stool and prevent constipation
  • Do pelvic floor muscle exercises to prevent urinary problems (incontinence)
  • Take a vacation for 4-8 weeks before being admitted to hospital
  • Prepare comfortable clothes
  • Study information about using urinary catheter or ask your doctor about it
  • Ask somebody to stay with you and help with activities of daily living for the first few days after the surgery

The first technique of radical prostatectomy was open prostatectomy, which requires a long skin incision. Nowadays open approach is used less often, only when the volume of prostate is more than 100 gr or laparoscopic approach is impossible due to certain reasons.

In radical retropubic prostatectomy skin incision starts from the belly button and goes down to  the pubic bone. Of course, the intervention is performed under general anesthesia, so the procedure is painless. Other variant is providing spinal or epidural anesthesia in combination with sedative drugs. This approach allows lymphatic nodes revision (during the surgery or afterwards), as the field of view is really vast. After the completion of surgery a urinary catheter is put into the penis in order to ease urination. Use of the catheter will be helpful during the first 1-2 weeks after the procedure.

When radical perineal prostatectomy is performed, skin incision is half-round and is located between anus and scrotum. This technique is performed under the same types of anesthesia, but is less traumatic and requires less time. Negative moments are high risk of erection problems development and bad access to lymphatic nodes (actually, they can`t be removed via this approach). Use of the urinary catheter is necessary as well.

Variant of partial prostate removal is transurethral resection of the prostate (TURP). Actually, primary indication for this procedure is benign prostatic hyperplasia and concomitant urination problems due to the narrowing of the urethra. In addition, TURP may be performed for relieving the same symptoms in men with advanced prostatic cancer. During this procedure the inner part of the prostatic gland is removed with the help of laser or electricity via the urethra, so the skin remains undamaged. Surgery is absolutely painless, as general or spinal anesthesia is applied. It takes no longer than an hour to perform the whole procedure. A urinary catheter is put in as well, but it is no longer needed in 1-2 days.

In spite of minimal damage, TURP side effects include presence of blood in the urine, infection, slow urine flow due to scar tissue, erectile dysfunction and retrograde ejaculation. However, good qualification of the surgeon minimizes these risks.

Radical prostatectomy: laparoscopic approach

Laparoscopic radical prostatectomy, or keyhole surgery, is the new approach to prostatectomy performing. This technique involves removing the prostate via several small incisions. That is why the surgery is less traumatic, blood loss in minimal, pain syndrome is significantly less pronounced, staying in the hospital is reduced to 1 day, and fast recovery is provided. One possible restriction is inability to convert the surgery into the open one and make intervention more comprehensive in the case of necessity.

It should be noted, that the result of laparoscopic prostatectomy depends to a great extent on the qualification of the surgeon. Beyond all doubt, high-technology equipment ensures certain advantages, but a surgeon is still the one, who performs the intervention. No equipment will help in absence of skilled and experienced healthcare professional.

Robotic-assisted laparoscopic radical prostatectomy is the newest technique, which was implemented into the clinical practice during the last two decades. This kind of intervention is performed with the help of da Vinci Surgical System. Specific high-quality equipment, four-armed robotic system, makes it possible to perform minimally invasive prostatectomy. As it was mentioned before, qualification of the surgeon is of primary importance in this case. The surgeon must be an expert not only on laparoscopic procedures, but also with using the da Vinci Surgical System. A doctor is considered to be skilled enough once he has performed more than 100 surgeries. The rate of successful surgeries is usually available on the hospital`s web-site.

Prostatectomy with the help of da Vinci Surgical System starts from the introduction of micro-surgical instruments and high-definition camera inside patient`s body. General anesthesia is provided in advance, so the patient doesn`t feel any pain. After that doctor goes to the operation room and connects to the system. Da Vinci Surgical System transforms movements of surgeon`s hand into the precise movements of the inserted instruments. It is a real time procedure, so the surgeon feels completely involved in the process.

It should be noted that the system is working only under surgeon`s control. That is why choosing the right specialist is extremely important. Automatic surgery or preliminary programming of the system is totally impossible. The procedure finishes with removal of the instruments and suturing tiny skin incisions.

During the prostatectomy with the help of da Vinci Surgical System  the surgeon works while in comfortable position, sitting in front of the control panel. He sees a magnified high-definition 3D view of the prostate and the whole surgery area.

The benefits of such procedure are obvious:

  • Greater precision, better dexterity when separating blood vessels and nerves
  • Improved visualization, invisible for the naked eye aspects are perfectly seen
  • Increased range of motion, access to hard-to-reach areas
  • Ability to spare healthy tissues, not affected by cancer, in a proper way
  • Ability to spare nerves and thus reduce risk of complications development

When prostatectomy is successfully completed, additional investigation of removed material starts. Pathologist specifies type of the tumor, its growth outside the prostate and, the most important aspect, presence of cancer cells on the margins of removed tissue (so-called “positive or negative surgical margins”).

Revealing positive surgical margins means that tumor may not be removed completely. Percentage of operations with negative surgical margins is as important for surgeon`s qualification, as the number of performed interventions.

Coping with possible risks and side effects of radical prostatectomy

As with each and every surgical intervention, radical prostatectomy has certain risks:

  • Abnormal reaction to anesthesia drugs
  • Bleeding during the surgery and afterwards
  • Thrombosis of legs and lungs
  • Injury to nearby organs (this mainly happens during robotic interventions, when surgeon is not skilled enough)
  • Infection
  • Abnormal collection of lymph in case of removal of lymphatic nodes

These risks can be successfully avoided by appropriate preparation, which was mentioned above, and with a careful selection of the surgeon. Side effects of radical prostatectomy mainly depend on the qualification of the surgeon as well. Some of them are temporary and will disappear with the course of time; others are stable and need additional treatment. Most typical side effects of radical prostatectomy are described below.

Urinary incontinence. This is a complete or partial loss of ability to control urination or having leakage.

There are few types of urinary incontinence:

  • Stress incontinence is the most typical form of the disorder. It is connected to the damage of bladder sphincter muscles or nerves. In this case urine is released when a person is coughing, laughing or doing physical activity.
  • Overflow incontinence feels like a complication when emptying the bladder. It arises when scar tissue blocks or narrows the upper part of urinary tract and disturbs the natural flow of the urine. In acute cases it should be corrected surgically.
  • Urge incontinence means that the bladder is hypersensitive. Minimum amounts of the urine irritates it and results in the passing of urine.
  • Continuous incontinence is a rare but serious complication. It is characterized by a total loss of ability to control urination.

Usually it takes several weeks or months to return the process of urinating back to normal. During this time a patient may use absorbent pads or pants. It should be noted that doing pelvic floor exercises before the surgery strengthens muscles, which are used during the urination, and helps to fight against urinary incontinence.

Erectile dysfunction (impotence) is the absence of  a good-quality erection enough for normal sexual intercourse. This side effect is extremely important for many men, so nerve-sparing surgery is always performed once nerves are not affected by cancer. The ability to spare responsible for the erection nerves depends to a great extent on the experience of the surgeon. Nevertheless, erection with certain medicinal help is still possible even in case of removing both nerves.

As it may take anything from months to years to restore erectile function completely, these measures can be helpful in improving sexual intercourse:

  • Drugs of phosphodiesterase-5 (PDE-5) inhibitors group (e.g. Viagra, Sialis, Levitra). These drugs are effective in case of viability of at least one nerve.
  • Vacuum devices, which create the erection mechanically.
  • Penile implants, which restore the erection in most complicated cases. This is a kind of surgical intervention as well.

To be precise, erectile dysfunction might be connected not only with nerve damage, but also with the psychological problems and general fatigue after the surgical treatment.

Changes in orgasm. Orgasm doesn`t disappear after the treatment, but it changes – becomes “dry”. This is connected with the removal of seminal vesicles and prostate, that produce fluid for the semen.

Loss of fertility. Radical prostatectomy destroys connection between testicles (source of sperm) and urethra, so the sperm doesn`t leave the body and there is no ejaculation. Produced sperm is reabsorbed inside the body; this is completely safe for the body. Option of fathering a child is still available in such situation. Patient should “bank” sperm before the intervention, so it can be used for artificial insemination in the future. Regardless loss of fertility, patients should continue using condoms for prevention of sexually transmitted diseases.

Lymphedema. In case of removing many lymphatic nodes around the prostate, the lymph might start collecting in the genital region or legs. This results in edema and pain. The most effective way of treatment for such condition is physical therapy.

Change in penis length. Not significant shortening or shrinkage of the penis may arise due to urethra cut and low level of androgens. Nevertheless, these changes usually don`t influence sexual function dramatically.

Inguinal hernia. Patients after radical prostatectomy have increased risk of inguinal hernia development. This can be somewhat prevented with the help of regular physical activity and strengthening of muscles.

Is it necessary to remove testicles in addition?

Orchiectomy, or surgical castration, may be helpful in the treatment of prostate cancer. To understand the mechanism of its positive action we should know that androgens (male hormones) make prostate grow and at the same time promote the progression of prostate cancer.

Androgens (testosterone and dihydrotestosterone) are produced by testicles and adrenal glands (tiny amount). With decreasing androgens level we are able to slow down the growth of the tumor or even reduce it in size. Such treatment option is called “hormone therapy”. Sole hormone therapy is not a cure for prostate cancer, but is an appropriate component of complex treatment schemes.

Hormone therapy is administered in such circumstances:

  • When surgery and radiation therapy are contraindicated or not effective (e.g. in advanced cancer cases)
  • When the relapse after surgery and radiation therapy is diagnosed
  • In order to reduce tumor size before radiation therapy
  • Along with radiation therapy or as an additional treatment if the risk of relapse is high

There are two main types of conducting hormone therapy:

  1. Medical treatment with several groups of drugs. The first one is LHRH agonists and antagonists. These drugs suppress production of the androgens in testicles. Regardless it has a great effect at a high cost and shrinkage of testicles (as they don`t work anymore) should be noted. The second common group of drugs is anti-androgens, which block androgen receptors in the prostate, so the gland becomes “blind” and can`t see hormones. Anti-androgens should be taken daily to support the effect. The third group of drugs is estrogen drugs. Estrogens are female hormones, so they have opposite action. This group of drugs is prescribed rarely due to the presence of serious side effects.
  2. Orchiectomy. This is irreversible surgical removal of testicles. Orchiectomy is a simple outpatient procedure, during which the doctor makes a small cut in the scrotum, removes testicles and fixes skin incisions with absorbable stitches. If it is important for the patient, artificial testicles (prostheses) might be inserted into the scrotum to restore a natural look. This treatment option is deprived of risks and side effects of medicinal treatment, but may be hard psychologically. In the end, both treatment options have the same result, the patient should understand this clearly.

Side effects of hormone therapy mainly arise due to higher levels of female hormones. Possible complications of the treatment include erectile dysfunction, reduced sexual desire, shrinkage of the testicles and penis, reduction of muscle mass, gaining weight, osteoporosis, anemia, depression and breasts enlargement and tenderness. Additional medicinal treatment is prescribed to ease side effects of the main treatment.

What happens once the surgery is done?

In absence of surgical complications it usually takes about 6 weeks to completely get back to normal life. Long-distance driving is allowed in approximately 4 weeks, but you should additionally clear up this question with your insurance company. Also there might be some restrictions in going back to work; it depends on the nature of your duties.

You will visit your general practitioner in 4-6 weeks after the surgery. Follow-up visits will not be frequent – you will see a doctor every 3-6 months. Frequency of visits is individually determined and depends on the stage of disease, results of treatment (e.g. results of prostate pathological examination and presence of positive or negative surgical margins), administration of additional drug treatment and its side effects.

You may discuss with your doctor options of fighting against relapses, such as regular physical activity, reducing excessive body mass, quitting smoking and correcting nutrition habits. Also your general practitioner will always help you in coping with prostatectomy side effects. Emotional support is no less significant than the physical state is, so you may be advised to visit a psychotherapist, if necessary.

Choosing the best doctor for performing a radical prostatectomy

As noted above, choosing a skilled surgeon determines a good outcome of the intervention, provides absence of complications in the early postoperative period, and minimizes the risk of such serious side effects, as incontinence and erectile dysfunction. The best up-to-date and high-technology equipment will never replace the experience of the doctor. Moreover, doctors should be keen to work with such equipment, otherwise it will cause more harm than good. One more important aspect is the quality of nursing care. This may seem less significant, but competent nurses will ease your state in the postoperative period and help in quick recovery.

Taking into consideration all  of the abovementioned factors, many men seek medical help abroad. In the modern world rating and qualification of urological surgeons can easily be found online, as well as patient`s reviews and stories about treatment experience. In this scope, patients often take a decision on having surgery in Germany- as hospitals of Berlin, Cologne and Leverkusen are famous worldwide in this relation. Applying directly to the hospital will put you in the end of a long queue of international patients. This is natural, as German citizens have higher priority when it comes to receiving high-technology surgical treatment. In addition, administrative workers, who receive these applications, may have difficulties with medical documents, as some information is clear only for doctors.
