The overall malignancy risk in ASyS appears low. Age and length of follow-up were associated with higher malignancy risk, whereas clinical manifestations were not. Although the malignancy rates differed between antibody subtypes, with the numerically highest prevalence in anti-OJ antibodies, these findings were not statistically significant. Since the risk of malignancy in the ASyS population appears to be low in general, cancer screening should be tailored according to the patients age and sex.
