Lung cancer after heart transplantation: results from a large multicenter registry.

In this study we analyzed Spanish Post-Heart-Transplant Tumour Registry data for adult heart transplantation (HT) patients since 1984. Median post-HT follow-up of 4357 patients was 6.7 years. Lung cancer (mainly squamous cell or adenocarcinoma) was diagnosed in 102 (14.0% of patients developing cancers) a mean 6.4 years post-HT. Incidence increased with age at HT from 149 per 100 000 person-years among under-45s to 542 among over-64s; was 4.6 times greater among men than women; and was four times greater among pre-HT smokers (2169 patients) than nonsmokers (2188). The incidence rates in age-at-diagnosis groups with more than one case were significantly greater than GLOBOCAN 2002 estimates for the general Spanish population, and comparison with published data on smoking and lung cancer in the general population suggests that this increase was not due to a greater prevalence of smokers or former smokers among HT patients. Curative surgery, performed in 21 of the 28 operable cases, increased Kaplan-Meier 2-year survival to 70% versus 16% among inoperable patients.

The prognosis of noncutaneous, nonlymphomatous malignancy after heart transplantation: data from the Spanish Post-Heart Transplant Tumour Registry.

INTRODUCTION: Malignancy is a major complication in the management of solid organ transplant patients. Skin cancers show a better prognosis than other neoplasms, but not all others are equal: Ideally, patient management must take into account the natural history of each type of cancer in relation to the transplanted organs. We sought to determine the prognosis of various groups of noncutaneous nonlymphomatous (NCNL) cancers after heart transplantation (HT). METHODS: We retrospectively analyzed the records of the Spanish Post-Heart-Transplant Tumour Registry, which collects data on posttransplant tumors in all patients who have undergone HT in Spain since 1984. Data were included in the study up to December 2008. We considered only the first NCNL post-HT tumors. RESULTS: Of 4359 patients, 375 developed an NCNL cancer. The most frequent were cancers of the lung (n=97; 25.9%); gastrointestinal tract (n=52; 13.9%); prostate gland (n=47; 12.5%; 14.0% of men), bladder (n=32; 8.5%), liver (n=14; 3.7%), and pharynx (n=14; 3.7%), as well as Kaposi's sarcoma (n=11; 2.9%). The corresponding Kaplan-Meier survival curves differed significantly (P<.0001; log-rank test), with respective survival rates of 47%, 72%, 91%, 73%, 36%, 64%, and 73% at 1 year versus 26%, 62%, 89%, 56%, 21%, 64%, and 73% at 2 years; and 15%, 51%, 77%, 42%, 21%, 64%, and 52% at 5 years post-diagnosis, respectively. CONCLUSION: Mortality among HT patients with post-HT NCNL solid organ cancers was highest for cancers of the liver or lung (79%-85% at 5 years), and lowest for prostate cancer (23%).
