As patients with end-stage renal disease are receiving renal allografts at older ages, the number of male renal transplant recipients RTRs being diagnosed with prostate cancer CaP is increasing. Historically, the literature regarding the management of CaP in RTR's is limited to case reports and small case series. To date, there are no standardized guidelines for screening or management of CaP in these complex patients.

To better understand the unique characteristics of CaP in the renal transplant population, we performed a literature review of PubMed, without date limitations, using a combination of search terms including prostate cancer, end stage renal disease, renal transplantation, prostate cancer screening, prostate specific antigen kinetics, immuno-suppression, prostatectomy, and radiation therapy. Of special note, teams facilitating the care of these complex patients must carefully and meticulously consider the altered anatomy for surgical and radiotherapeutic planning.

Active surveillance, though gaining popularity in the general low risk prostate cancer population, needs further study in this group, as does the management of advance disease. This review provides a comprehensive and contemporary understanding of the incidence, screening measures, risk stratification, and treatment options for CaP in RTRs.

In , nearly It is widely acknowledged that patients are receiving grafts at older ages and are experiencing longer life expectancies with sustained renal function. Treating these patients for non-transplant related conditions, including prostate cancer CaP , has become more frequent. In this review, we provide a comprehensive and contemporary assessment of CaP risk, screening, and treatment effectiveness in the renal transplant population.

We utilized a pre-determined search strategy including the terms prostate cancer, end stage renal disease, renal transplantation, prostate cancer screening, prostate specific antigen PSA kinetics, immunosuppression, prostatectomy, and radiation therapy. Compared to age-matched controls in the general population, transplant recipients are at an increased risk for a variety of malignancies.

Overall, the 5-year incidence of cancer in solid organ transplant recipients is 4. Among RTRs, genitourinary malignancies are the third most common malignancy behind de novo skin malignancies and post transplant lymphoproliferative disorder 3 , 4.

Of the genitourinary malignancies, CaP is the most common 5. Recently reported standardized incidence ratios for CaP in solid organ transplant recipients are variable, ranging from 0. Data from the 's and 's suggested that transplant patients were not at increased risk for CaP 3 , However, many theorize that CaP has become more frequent in the RTR population due to increased allograft survival, increasing recipient age, and more rigorous screening.

Variability in reported incidence may also be attributed to differences in study design, geography, screening practices, reporting criteria, sample size, and the immunosuppressive regimen used 3 , 6 , 11 — More recent data indicates that renal transplant recipients do indeed have a higher incidence of CaP.

Current U. Medicare data reveals a 3-year CaP incidence of 1. Similarly, data from 22 transplant centers in France has revealed a similar two-fold increase incidence of CaP 1. Hall et al. Best recommendations for CaP screening remain a point of contention in both the general and renal transplant populations. To date, there are no standard CaP screening regimens or established guidelines regarding prostate specific antigen PSA testing or cut-offs in pre or post—transplant patients.

However, the validity of these recommendations has not been evaluated in a randomized controlled manner. It is unclear whether CaP screening is of benefit in the pre-transplant population, as the median survival for ESRD patients on hemodialysis is only 5 years and CaP is unlikely to cause significant mortality within that time period However, post-transplant life expectancies now often reach well beyond 15 years, making the diagnosis and treatment of CaP in RTRs a realistic life-extending measure.

Yet, screening for CaP in RTRs may still be less cost effective and result in less overall benefit when compared to the general population. Kiberd et al.

Compared to the general population, it is estimated that three times more RTRs over age 65 must be screened with annual DRE and PSA to save one life number needed to screen of 96 vs. Serum f-PSA levels are significantly higher in hemodialysis patients, but are not significantly elevated in patients undergoing continuous ambulatory peritoneal dialysis.

After renal transplantation, t-PSA levels are relatively unchanged. Therefore, t-PSA is the most reliable CaP marker in both pre-transplant patients on dialysis and in the early post-transplant population 24 — 26 , 28 — Although t-PSA does not seem to be significantly affected by renal transplantation itself, interpretation of PSA in RTRs may need to be adjusted based on immunosuppression regimen.

Retrospective analysis by Chamie and colleagues has revealed that, among patients with similar PSA levels prior to renal transplant, post-transplant PSA was significantly lower in patients taking sirolimus 0. Subsequent transrectal ultrasound guided biopsy is performed if t-PSA is abnormally elevated 27 Although not specifically studied in RTRs, multiparametric magnetic resonance imaging mp-MRI is emerging as an accurate tool for identifying clinically relevant prostate tumors.

Mp-MRI can be used to identify significant lesions prior to a target biopsy or as a cancer staging tool after a positive biopsy MRI can also help rule out CaP metastases and aid in identifying the location of important structures namely the transplant allograft and the transplant ureter prior to CaP treatment Risk is minimal among patients with milder degrees of renal insufficiency 39 , American Urological Association guidelines recommend antibiotic prophylaxis in all patients undergoing TRUS-guided prostate biopsy.

Multiple randomized controlled trials have shown a decrease in infectious complications of prostate biopsy with single-dose antibiotic prophylaxis. Aztreonam can be used instead of an aminoglycoside in patients with renal insufficiency Although no specific guidelines exist for antibiotic prophylaxis in the undoubtedly higher risk transplant recipient, similar recommendations can be applied to this population.

In small prospective studies, TRUS-guided prostate biopsy has been shown to be well tolerated in patients receiving immunosuppression, with no increased risk of infection compared to the general population Nonetheless, careful consideration to culture directed prophylaxis may be crucial to minimizing the risk of infectious complications in RTRs exposed to multiple hospitalizations, previous exposure to multiple antibiotics, and concomitant immunosuppression When choosing a prophylactic regimen, it is also important to consider that one fourth of RTRs will develop a urinary tract infection within one year of transplantation.

A urinalysis and culture should be checked and any active urinary tract infection should be fully treated prior to proceeding with prostate biopsy. Because RTRs represent a population at high risk for harboring resistant organisms, they may also benefit from pre-biopsy rectal swabs for directed prophylaxis.

Use of immunosuppression has been linked to a variety of malignancies, but the association of immunosuppression and CaP is less clearly delineated. There are no large-scale comprehensive studies with adequate follow-up to assess whether immunosuppression truly increases risk of CaP occurrence, recurrence, or progression.

Nonetheless, CaP is diagnosed at earlier ages in RTRs which may be due to more diligent screening or an actual increased predilection for CaP. Men with HIV on a variety of immunosuppression regimens also develop CaP at increased incidence and at earlier ages compared to the general population, indicating that immunosuppression may indeed be implicated 46 , It has been postulated that a healthy immune system is essential for the inhibition of CaP cell growth.

When CaP cell lines are exposed to a healthy conditioned media containing normal T-lymphocytes, they demonstrate decreased growth. CaP cells appear to respond differently based on the type of immunosuppressive agent introduced.

In vitro studies and animal models suggest that calcineurin inhibitors CNIs increase aggressiveness and progression of CaP. Cyclosporine has been shown to induce phenotypic changes that make various forms of adeno-carcinoma more aggressive.

In murine models of prostate adenocarcinoma, cyclosporine increases the size and number of lymph node and pulmonary metastases. Azathioprine AZA has been strongly linked to an increase in skin malignancies and may also have a stimulatory influence on CaP cells. Use of AZA was the only independent risk factor for advanced disease in this cohort.

However, other studies have shown no increased risk of CaP in association with AZA or mycophenolate 15 , 51 , Other immunosuppressive agents may be protective against CaP. In , Kauffman and colleagues evaluated data from The authors concluded that the use of mTOR inhibitors alone or in combination with other immunosuppressive agents may reduce the incidence of CaP in RTRs. Combination therapy is often used to reduce the toxicity of individual agents In conclusion, current data suggests that cyclosporine, tacrolimus, and AZA are associated with a higher risk of malignancy, which may include CaP.

In contrast, mTOR inhibitors are associated with a decreased incidence of malignancy, and should considered for use in higher risk patients Reduction of immunosuppression is frequently instituted after CaP diagnosis, but to date there is no data showing any benefit with regards to prognosis. It is postulated by some that the intensity of therapy, rather than choice of agent, is related to increased CaP risk. Therefore, the lowest possible dose of immunosuppression while maintaining rejection-free graft survival is advised There are a number of important considerations when deciding on treatment approach, mainly because of the proximity of the allograft and transplant ureter to the surgical or treatment field.

A summary of surgical series reporting prostatectomy approaches and outcomes in RTRs is shown in Table Regardless of approach, prostatectomy in transplant patients poses a number of unique challenges. Previous transplant surgery leads to distortion of normal anatomy and the renal allograft limits exposure within the pelvis. RTRs with a history of peritoneal dialysis are likely to have thickening of the peritoneum and obliteration of normal tissue planes.

Performance of a bilateral lymph node dissection in RTRs may be difficult, dangerous, or nearly impossible as most allografts are oriented along the iliac vessels. In many instances, it may only be possible to perform a contralateral lymphadenectomy. Doing so is not without future risk; extensive lymphadenectomy may render the contralateral iliac vessels unusable for future allograft implantation should the current graft fail at a later date.

Despite these challenges, the literature supports the safety and efficacy of prostatectomy in the post-transplant population. Disease specific and overall mortality after aggressive surgical therapy in transplant patients is comparable to that in the non-transplant population.

There is no data on active surveillance for prostate cancer in the renal transplant population. Conceptually, this may become an evolving arena in which the application of advanced biomarker evaluations and tissue genomics plays an increasing role in predicting who is a candidate for such an approach.

In the future, multi-parametric magnetic resonance imaging mpMRI may shed some light on the presence or absence of prostate lesions of significance, provided the glomerular filtration rate permits the administration of gadolinium, which may help to guide decisions for intervention.

Inherent dangers of RRP in RTRs became evident, including the insertion of deep retractors that can damage the allograft and ureter Regardless of surgeon experience, visualization during RRP in RTRs is likely to be limited due to the pelvic renal allograft.

Specifically, dissection to achieve bladder descent is challenging due to a tethering effect from the transplant ureteroneocystostomy Most urologists avoid lymph node dissection ipsilateral to the transplant kidney to avoid the risk of allograft injury.

However, bilateral lymph node dissection can be completed if deemed necessary. Kinahan and colleagues reported bilateral ileo-obturator lymph node dissection by using modified placement of Wilkinson retractors to gain exposure while preventing pressure damage to the transplant kidney Placement of a transplant ureteral stent prior to prostatectomy may help with transplant ureteral identification if bilateral lymphadenectomy is to be performed.

In the early postoperative period, it is felt that immunosuppression does lead to delayed wound healing and may contribute to an increased risk of perioperative infection Although RRP has been performed safely in RTRs with relatively efficient operative times, blood loss and hospital stays are significantly increased compared to laparoscopic and robotic assisted approaches Table The main benefit is minimal dissection near the renal allograft and transplant ureter.

With the perineal approach, bladder descent is not impaired and vesicourethral anastomosis can be performed without tension. PRP also preserves access to the iliac fossa should the need for a second transplant arise in the future. Small series report operative times comparable to RRP, while blood loss and length of stay tend to be lower 61 ,

The type of surgery you have depends mainly on the stage of the cancer. When planning surgery, your healthcare team will also consider other factors, such as your age, overall health and life expectancy. Surgery may be done for different reasons. You may have surgery to: completely remove the tumour remove as much of the tumour as possible called debulking before other treatments reduce pain or ease symptoms called palliative surgery treat cancer that comes back recurs after other treatments called salvage surgery.

The following types of surgery are commonly used to treat prostate cancer. You may also have other treatments before or after surgery. A radical prostatectomy removes the prostate and some tissues around it, including the seminal vesicles.

The surgeon may also remove lymph nodes from the pelvis called a pelvic lymph node dissection at the same time as doing a radical prostatectomy.

A radical prostatectomy is the most common surgery used to treat prostate cancer. It may also be used to treat men whose PSA level starts to rise after treatment with radiation therapy or cryosurgery called a biochemical recurrence or biochemical failure.

When this surgery is used to treat a recurrence, it is called salvage surgery or a salvage radical prostatectomy. Surgeons can use different approaches and techniques to remove the prostate. They can make a large incision cut to reach the prostate called open surgery. They can also use laparoscopic or robotic techniques, which are done through smaller incisions in the pelvis. These types of surgery are less invasive than a radical prostatectomy. Men often have shorter recovery times, less blood loss, less pain and shorter hospital stays with these procedures as well.

Retropubic radical prostatectomy is done through an incision in the lower abdomen. The surgeon can also remove lymph nodes from the pelvis through the same incision.

In Canada, it is the most common approach to removing the prostate to treat cancer. Perineal radical prostatectomy is done through an incision in the area between the scrotum and the anus called the perineum. Laparoscopic radical prostatectomy uses a laparoscope a tube-like instrument with a light and tiny video camera and other surgical instruments passed through small cuts. Robotic radical prostatectomy is a type of robotic surgery. The surgeon sits near the operating table and uses remote controls to move robotic arms.

The robotic arms have tiny video cameras and surgical instruments that remove tissue through small cuts. The robotic arms can bend and turn like a human wrist. Nerve-sparing radical prostatectomy avoids damaging the nerves to the penis, which helps lower the risk of erectile dysfunction.

It may be an option with any of the approaches to radical prostatectomy, but it is more successful with early stage prostate cancer and in younger, sexually active men. It is difficult for surgeons to know before surgery if the nerves can be spared.

So they will decide if nerve-sparing surgery is possible when they see the prostate and tumour during surgery. TURP removes part of the prostate through the urethra. The surgeon passes a resectoscope through the tip of the penis and up the urethra to reach the prostate. A resectoscope is a type of endoscope that uses a magnifying instrument with a light and video camera. The surgeon passes tools through the resectoscope and uses a thin wire with an electric current or a laser to cut away and remove prostate tissue around the urethra.

TURP is most commonly used to treat benign prostatic hyperplasia, which is a non-cancerous condition of the prostate. It is sometimes used to help relieve urinary problems caused by an enlarged prostate blocking the urethra.

This is done as palliative treatment for men with advanced prostate cancer or men who are not healthy enough for radical prostatectomy. Cryosurgery is a procedure that destroys cancer cells by freezing them. It is also called cryoablation, cryosurgical ablation or cryotherapy.

Cryosurgery delivers an extremely cold liquid or gas to the prostate through a metal tube called a cryoprobe. The doctor will often use a transrectal ultrasound to guide the cryoprobe to the tumour. The area is allowed to thaw and then is frozen again. The freeze-thaw cycle may need to be repeated a few times. Find out more about cryosurgery. A PLND also called a pelvic lymphadenectomy removes lymph nodes from the pelvis. The surgeon can use an open or laparoscopic approach to remove the lymph nodes.

A pelvic lymph node dissection may be done during the same surgery as a radical prostatectomy or it may be done as a separate procedure.

Doctors do a pelvic lymph node dissection to find out if the cancer has spread to the pelvic lymph nodes. Find out more about a pelvic lymph node dissection PLND. Some men have many side effects. Other men have only a few side effects. If you develop side effects, they can happen any time during, immediately after or a few days or weeks after surgery. Sometimes late side effects develop months or years after surgery. Most side effects will go away on their own or can be treated, but some may last a long time or become permanent.

Side effects of surgery will depend mainly on the type and site of surgery and your overall health. Surgery for prostate cancer may cause these side effects: bleeding and infection sexual problems , including erectile dysfunction and changes in orgasm loss of bladder control called urinary incontinence a buildup of lymph fluid called lymphedema swelling in the genital area leakage of feces from the anus leakage of urine during ejaculation called climacturia.

Tell your healthcare team if you have these side effects or others you think might be from surgery. The sooner you tell them of any problems, the sooner they can suggest ways to help you deal with them. Find out more about surgery and side effects of surgery.
