Case report: role of multidisciplinary approach in a case of spine osteosarcoma with oligometastatic heart disease

Introduction. Primary spinal osteosarcoma and rare metastatic heart lesion are considered significant factors for poor prognosis. The available work indicates that combined treatment, including the radical surgery of heart solitary metastatic lesion, probably provides the best outcome.

Case report. Man, 27-year-old, with Th8 spinal osteosarcoma and solitary left atrial metastasis. From October 2019 to February 2020 5 cycles of chemotherapy (high doses of platinum and doxorubicin) were carried out with positive effect. Next steps were surgery: March 2020 – spondylectomy of the Th8 vertebra with combined stabilization; September 2020 – subtotal resection with plasty of the right atrium, tricuspid valve and prosthesis of the right coronary artery. Between the first and second surgery, 4 more same chemotherapy cycles were carried out. Currently, 24 months after completion of treatment, there are no signs of the disease.

Conclusion. The article presents a unique case of treatment of primary osteosarcoma and metastatic lesion of rare location. Multidisciplinary approach and combination treatment in specialized centers increase the probability of favorable outcome in such cases.
