Prostate Cancer After Heart Transplantation: Unicenter Case-Control Study

[Localized Prostate cancer in candidates for renal transplantation and recipients of a kidney transplant: The French Guidelines from CTAFU]

OBJECTIVE

To define guidelines for the management of localized prostate cancer (PCa) in kidney transplant (KTx) candidates and recipients.

METHOD

A systematic review (Medline) of the literature was conducted by the CTAFU to report prostate cancer epidemiology, screening, diagnosis and management in KTx candidates and recipients with the corresponding level of evidence.

RESULTS

KTx recipients are at similar risk for PCa as general population. Thus, PCa screening in this setting is defined according to global French guidelines from CCAFU. Systematic screening is proposed in candidates for renal transplant over 50 y-o. PCa diagnosis is based on prostate biopsies performed after multiparametric MRI and preventive antibiotics. CCAFU guidelines remain applicable for PCa treatment in KTx recipients with some specificities, especially regarding lymph nodes management. Treatment options in candidates for KTx need to integrate waiting time and access to transplantation. Current data allows the CTAFU to propose mandatory waiting times after PCa treatment in KTx candidates with a weak level of evidence.

CONCLUSION

These French recommendations should contribute to improve PCa management in KTx recipients and candidates, integrating oncological objectives with access to transplantation.

Robot-assisted laparoscopic radical prostatectomy after heart transplantation

Prostate cancer (CaP) is the leading visceral malignancy in males. Patients who undergo cardiac transplantation are immune compromised, thus presenting a therapeutic challenge. Immunosuppresion could accelerate tumor growth, while medical intervention may be associated with increased treatment mortality or morbidity. Due to paucity of such cases, there are no randomized trials that address the treatment algorithm for cardiac transplant patients with CaP, with only a few scattered reports in the literature. Treatment options range from hormonal manipulation to radiation therapy to radical prostatectomy. To our knowledge, we report the first successful robot-assisted laparoscopic radical prostatectomy in a heart transplant patient with CaP.

Cytomegalovirus prostatitis in a heart transplant recipient

Cytomegalovirus (CMV) is the most common viral infection affecting the posttransplantation course of organ recipients. However, CMV involvement of the prostate even in immunocompromised hosts is rare. We describe the first case in the heart transplant literature of a 59-year-old heart recipient with CMV prostatitis. An elevated PSA prompted a prostate biopsy revealing an adenocarinoma, chronic prostatitis as well as viral cytopathic effect consistent with CMV infection. CMV PCR in the blood was negative. A few months prior, the patient developed CMV viremia and was treated initially with ganciclovir intravenously and subsequently with valganciclovir and CMV immunoglobulins. The patient did well with brachytherapy and additional anti-CMV agents. We discuss the role of CMV in the prostate and management of CMV prostatitis. Relationships between CMV, prostate cancer and heart transplantation are also outlined.

Prostate cancer screening and treatment in the transplant population: current status and recommendations

PURPOSE

We reviewed the current status of and recommendations for prostate cancer screening and treatment in the solid organ transplant population.

MATERIALS AND METHODS

We performed a MEDLINE search to identify published data regarding prostate cancer screening, risk, treatment and outcomes in the solid organ transplant population. The literature was reviewed and summarized.

RESULTS

Most data regarding outcomes of prostate cancer treatment in the transplant population are limited to case reports and small series, and primarily involve renal insufficiency. It does not appear that the development or natural history of prostate cancer is significantly affected by organ failure or subsequent transplantation. Thus, prostate specific antigen testing and screening protocols can be extrapolated from the general population. However, the balance of comorbid diseases and estimated limitations in life expectancy must be carefully considered, and emphasis should be placed on risk assessment. Prostatectomy appears to be feasible with outcomes comparable to those in the non-transplant population, while data regarding the use of radiation therapy are limited.

CONCLUSIONS

The expansion of organ transplant criteria, including older donors and recipients, combined with improved allograft survival has enhanced the relevance of prostate cancer screening and treatment in this group. Greater awareness of the issues surrounding prostate cancer incidence, detection and natural history should promote improved data collection, screening and treatment of prostate cancer in the transplant population.
