Primary cardiac leiomyosarcoma, a rare heart tumor, was treated with surgery and chemotherapy in two patients. This aggressive approach, despite complications, appears to improve survival for this rare malignancy.

Area of Science:

  • Cardiovascular Pathology
  • Surgical Oncology

Background:

  • Primary cardiac leiomyosarcoma is an exceptionally rare malignant tumor originating in the heart.
  • Early diagnosis and intervention are critical for managing rare cardiac malignancies.

Observation:

  • Two patients presented with distinct manifestations: one with a pulmonary trunk tumor mimicking pulmonary embolism, and another with a left atrial tumor causing mitral valve dysfunction.
  • Both patients underwent surgical resection followed by adjuvant chemotherapy.

Findings:

  • Despite requiring multiple hospitalizations for treatment-related complications, both patients survived over 22 months post-operation.
  • The aggressive multimodal treatment strategy, including surgery and chemotherapy, demonstrated a positive impact on survival outcomes.

Implications:

  • Aggressive surgical excision combined with chemotherapy may offer improved survival for patients diagnosed with primary cardiac leiomyosarcoma.
  • These cases contribute to the limited understanding of managing rare cardiac tumors and highlight potential therapeutic strategies.
