Survival of Patients with Primary Cardiac Tumors in an 11-Year Single Center Study

BACKGROUND: Primary cardiac tumors are rare, but few studies have examined the relationship between risk factors and the prognosis. The aim of this study was to provide a survival analysis and risk factors for mortality in patients with primary cardiac tumors. METHODS: We retrospectively enrolled 71 patients diagnosed with primary cardiac tumors from June 2006 to November 2017 in our hospital. Patients' population characteristics, treatment information, pathology, and follow-up data were obtained and analyzed. RESULTS: Of the 71 patients, 60 cases were benign, and 11 cases were malignant. Sex, age, New York Heart Association classification, the percentage of peripheral embolism, and surgery had no significant difference between benign and malignant groups (P >.05), but the percentage of arrhythmia, leg edema, and mortality rate was higher in the malignant tumor group than in the benign tumor group (P <.05). Compared with the benign tumor group, the percentage of biatrial lesions in the malignant tumor group was significantly higher (P <.05). Moreover, Independent risk factors included the treatment choice, pathology type, and number of tumor lesions (P <.05). CONCLUSION: Our study suggests that conservative therapy, malignant cardiac tumor, and biatrial tumor lesion are independent risk factors for poor prognosis.
