Long-term follow-up of lung and heart transplant recipients with pre-transplant malignancies.

BACKGROUND: Concern regarding recurrence of pre-transplant (Tx) malignancy has disqualified patients from Tx. Because this has been poorly studied in lung and heart Tx recipients our aim was to investigate the influence of pre-Tx malignancy on post-Tx recurrence and long-term survival, focusing on pre-operative cancer-free intervals. METHODS: From our lung and heart Tx programs (1983 to 2011) we retrospectively identified 111 (lung, 37; heart, 74) of 3,830 recipients with 113 pre-Tx malignancies. The patients were divided into 3 groups by pre-Tx cancer-free interval: Group I, <12 months (n = 24); Group II, >= 12 to <60 months (n = 18); and Group III, >= 60 months (n = 71). RESULTS: Mean age at pre-Tx malignancy was 35 +/- 18 years. Mean post-Tx follow-up time was 70 +/- 63 months (range, 0-278 months), and malignancy recurrence was 63% in Group I, 26% in Group II, and 6% in Group III. Kaplan-Meier analysis of freedom from post-Tx recurrence revealed the following differences among the groups: Group I vs 11, p = 0.08; II vs III, p = 0.002; and I vs III, p < 0.001. Overall survival (51 deaths) was significantly poorer in Group I than in Groups II and III (p = 0.044). Survival between Groups II and III did not differ significantly (p = 0.93). CONCLUSIONS: Cancer-free survival of >= 5 years pre-Tx is associated with the lowest recurrence. However, recurrence is related to the time the patients were cancer-free, as seen in Groups I and II.
