Screening for solid organ malignancies prior to heart transplantation

Area of Science:

• Cardiology
• Oncology
• Transplantation Medicine

Background:

• Solid organ cancer in immunosuppressed patients has a poor prognosis.
• Early detection of asymptomatic carcinomas in potential transplant recipients is vital.

Purpose of the Study:

• To evaluate the effectiveness of an enhanced screening protocol for detecting pre-transplant malignancies in heart transplant candidates.
• To assess the impact of pre-existing malignancies on transplant eligibility and outcomes.

Main Methods:

• Sixty-seven heart transplant candidates underwent a modified screening protocol, including standard methods plus tumor markers (PSA, CEA), ultrasounds, CT scans, mammography/echography, PAP smear, and colonoscopy/prostate echography as indicated.
• Diagnostic additions aimed to increase the sensitivity of cancer detection.

Main Results:

• Carcinoma was detected in 10 of 67 patients (14.9%), with 8 denied transplantation.
• Enhanced screening protocols identified 9 of the 10 malignancies.
• Older patients (>55 years) had a significantly higher cancer detection rate (80% vs. 44%).
• Post-transplant, 5 of 36 recipients developed malignancies (4 skin, 1 lymphoma), with no malignancy-related deaths.

Conclusions:

• A comprehensive screening program is essential for triaging heart transplant candidates, particularly older individuals, to identify pre-existing malignancies.
• Enhanced screening protocols significantly improve the detection of asymptomatic cancers before transplantation.
• Identifying and managing pre-transplant cancer can impact transplant decisions and long-term patient health.
