Abstract
Background
The association between amyloidosis and cancer remains unclear.
Participants and methods
Using the Taiwan National Health Insurance Research Database we conducted a population-based cohort study. Patients newly diagnosed with amyloidosis between 1997 and 2009 were enrolled. Patients with antecedent cancer were excluded. Standardized incidence ratios (SIR) of cancers were calculated for the study cohort and compared with cancer incidence among the general population. We used a multivariate Cox regression model to evaluate the predictors of cancer development for patients with amyloidosis.
Results
The study included 1,693 subjects with median follow-up of 5.63 years. A total of 68 patients developed cancer. The incidence of kidney cancer (SIR 3.42; 95 % CI 1.11–7.97; p = 0.034) and hematologic malignancies (SIR 3.88; 95 % CI 1.86–7.14; p < 0.001) were significantly higher for patients with amyloidosis.
Conclusion
This is currently the largest study to evaluate cancer risk among patients with amyloidosis. The results indicate that amyloidosis may be associated with an increased risk of kidney cancer and hematologic malignancies.
