Is thyroid cancer prognosis affected by solid organ transplantation?

Area of Science:

• Oncology
• Transplant Surgery
• Endocrinology

Background:

• Thyroid nodules found during transplant evaluation may delay transplantation.
• Increased thyroid cancer incidence post-transplant is noted, but its prognostic impact is unclear.

Purpose of the Study:

• To evaluate the effect of solid organ transplantation on differentiated thyroid cancer prognosis.
• To determine if a history of thyroid cancer impacts transplant eligibility.

Main Methods:

• Retrospective review of patients with a history of differentiated thyroid cancer and solid organ transplantation.
• Analysis of cancer recurrence and survival outcomes in pre- and post-transplant cohorts.

Main Results:

• Out of 13,037 transplant patients, 94 had differentiated thyroid cancer (0.7%).
• Disease-free survival rates at 5 and 10 years were comparable between pre-transplant (95.8%, 92.1%) and post-transplant (89.7%, 84.4%) groups.
• No significant difference in recurrence or survival was observed based on transplantation status.

Conclusions:

• Solid organ transplantation does not adversely affect outcomes for patients with differentiated thyroid cancer.
• Thyroid cancer history or incidental nodules should not be a contraindication for solid organ transplantation.
