Sarcoma of the heart: survival after surgery

Malignant intracardiac tumours are rare, and consensus concerning the optimal therapeutic approach is lacking. We performed a retrospective medical analysis, identifying 9 patients having been operated for cardiac sarcomas. All of them had a complete postoperative long-term follow-up. To enhance understanding of the best therapeutic approach for future patients, it is crucial to reveal special medical problems and to analyse the potential impact they may have on disease course and survival rate in this specific patient group.

Cardiac tumours operated on 2000 to the end of 2015 were reviewed. Late mortality during the follow-up period was determined. The impact of tumour extension, tumour localization, resection status (complete versus partial) and histopathological diagnosis on survival was analysed retrospectively.

Of all cardiac malignant tumours resected, sarcomas were, with an incidence of 0.14% (9 patients), the most frequent histological group admitted to cardiac surgery. All of the patients presented with cardiac symptoms. All of the patients survived the operation and all had relief or improvement of cardiac symptoms. The mean follow-up period was 17 ± 13 months. Five patients died after 6, 8, 12, 12 and 15 months, respectively. Four survivors (3 with a pulmonary artery tumour sarcoma and 1 with a left atrial sarcoma) had a mean follow-up of 26 ± 17 months. Macroscopically complete tumour resection, absence of metastatic spread and histological sarcoma type had an impact on follow-up survival.

Although cardiac sarcomas are rare, surgeons occasionally encounter them. A 1-year mortality rate of 44% reflects an unfavourable prognosis, but surgery seems to be a secure, reliable option in selected patients for treating cardiac symptoms and avoiding early cardiac-related deaths.
