Malignancy after Solid Organ Transplantation: Comprehensive Imaging Review

Area of Science:

• Medical imaging
• Oncology
• Transplant medicine

Background:

• Immunosuppressive therapies have improved organ transplant survival rates.
• Chronic immunosuppression increases posttransplant malignancy risk, leading to advanced-stage cancers.
• Posttransplant cancers arise de novo, via donor transmission, or recurrence.

Purpose of the Study:

• To review the role of imaging in diagnosing and managing posttransplant malignancies.
• To discuss the mechanisms and types of posttransplant cancers.
• To outline strategies for improving outcomes in transplant recipients.

Main Methods:

• Review of literature on posttransplant malignancies and imaging.
• Analysis of pathogenic mechanisms of oncogenesis in transplant recipients.
• Discussion of diagnostic challenges and management strategies.

Main Results:

• Imaging is vital for screening, follow-up, and surveillance of posttransplant cancers.
• Benign conditions can mimic malignancies, necessitating pathological confirmation.
• Specific cancers have distinct origins (de novo, donor-related, recurrence).

Conclusions:

• Altered immune systems from immunosuppression are key to cancer development.
• Comprehensive management, including risk factor prevention and targeted screening, is essential.
• Timely diagnosis via imaging and appropriate treatment can reduce cancer-related morbidity and mortality.
