AIMS: Atherosclerosis and cancer share common risk factors and involve similar molecular pathomechanisms. Most clinical and epidemiological studies show a positive correlation between atherosclerosis and smoking-related cancers and heterogeneous results for non-smoking-related cancers. However, up-to-date large-scale autopsy studies including a detailed analysis of cancer types are lacking. Therefore, we sought to investigate the relation between major cancer types and the grade of atherosclerosis in a recent well-powered autopsy cohort. METHODS: In 2101 patients, both autopsy data and clinical data including demographics, disease groups, tumour type, cause of death and grade of atherosclerosis were reviewed and statistically analysed. RESULTS: We found cancer in general is associated with less atherosclerosis (OR 0.60, p<0.0001). In particular, haematological neoplasm and sarcomas were associated with much less atherosclerosis (OR=0.45, p<0.0001 and OR=0.43, p=0.087), while carcinomas were associated with moderately less atherosclerosis (OR=0.72, p=0.002). Furthermore, non-smoking-related cancers were associated with much less atherosclerosis (OR=0.41, p<0.0001), while possibly smoking-related cancer and smoking-related cancer showed no significant association. In a comprehensive analysis of 21 cancer types, biliary tract cancer, lymphomas/lymphoid leukaemias and kidney cancer were associated with much less atherosclerosis (OR=0.19, p<0.0001; OR=0.41, p<0.0001; and OR=0.48, p=0.029). In an exploratory analysis of treatment strategies, we found that tumours with a recommendation of oxazaphosphorines and pyrimidine antagonist treatment were significantly associated with less atherosclerosis (OR=0.33, p=0.0068 and OR=0.58, p=0.012). CONCLUSIONS: In conclusion, the study showed an inverse association between cancer and atherosclerosis postmortem that depends on the cancer type and suggests a possible impact of chemotherapy regimens.
