Survival Differences in Men and Women With Primary Malignant Cardiac Tumor: An Analysis Using the Surveillance, Epidemiology and End Results (SEER) Database From 1973 to 2015

Abstract

Background No data are available on sex disparities in prevalence and survival for primary malignant cardiac tumors ( PMCT ). This study aimed to compare male and female PMCT prevalence and long‐term survival rates. Methods and Results We utilized the Surveillance, Epidemiology, and End Results ( SEER ) 18 database from the National Cancer Institute for all PMCT s diagnosed between 1973 and 2015. From a total of 7 384 580 cases of cancer registered in SEER , we identified 327 men and 367 women with PMCT s. The majority (78%) of patients were white. Sarcoma was the most common type of PMCT in both men and women (≈60%). Individuals diagnosed with lymphoma exhibited better survival than those with other types of PMCT s. Men were diagnosed at a younger age than women; however, there was no significant difference in overall survival between the sexes. Men diagnosed with PMCT between the ages of 51 and 65 years demonstrated prolonged survival compared with those diagnosed at younger or older ages. There was no difference in survival rates among women based on age at diagnosis. Conclusions PMCT s are rare in both men and women. Tumors tend to be diagnosed at an earlier age in men compared with women, but there is no sex disparity in survival rate. Sarcoma is the most common type of PMCT , and lymphoma is associated with the highest survival rate among both sexes.
