title: Primary osteosarcoma of the heart with long-term survival: A case report of laparoscopic resection of a metastatic sarcoma in the intestine.
abstract: Primary cardiac tumors are uncommon and cardiac osteosarcoma is a rare disease. While complete surgical resection is considered to be the best treatment option for cardiac osteosarcomas, local and metastatic recurrences present challenges and indicate a poor prognosis. A combination of surgical resection with radio- and/or chemotherapy is a more effective course of treatment for osteosarcoma. In the present case, the patient underwent a complete resection of a primary cardiac osteosarcoma, and received chemotherapy and radiotherapy following local recurrence and metastasis to the bone post-operatively. Following these treatments, a rectal metastatic tumor was detected as causative of anemia. There is currently a lack of guidelines on the treatment of metastatic osteosarcomas in the intestine and there are few reports on rectal metastases. The present study described a laparoscopic resection of the osteosarcoma. The patient recovered without any complications and radiotherapy and chemotherapy were administered post-surgery to treat the bone metastases. The patient remained healthy at a follow-up examination, 61 months post surgery.
