Does localized radiotherapy reduce tumor size and improve symptoms in a patient with recurrent pulmonary artery leiomyosarcoma?
Does localized radiotherapy reduce tumor size and improve symptoms in a patient with recurrent pulmonary artery leiomyosarcoma?
Radiotherapy may offer a clinical benefit in reducing tumor size and improving quality of life for patients with recurrent pulmonary artery leiomyosarcoma who do not respond to chemotherapy.
May support radiotherapy for palliation in recurrent pulmonary artery leiomyosarcoma; leaves open confirmation in prospective studies.
Pulmonary artery (PA) leiomyosarcoma (PAL) is a rare but extremely malignant tumor of the cardiovascular system, which is often misdiagnosed as pulmonary thromboembolism. Although the early detection and surgical resection improves patient survival, the benefits of adjuvant therapy are not well understood. The current study presents the case of a patient with primary PAL who underwent surgical resection along with three courses of chemotherapy. Despite these interventions, the patient experienced recurrence of the PAL within four months following treatment. The patient received localized radiotherapy and subsequently achieved a stable disease state. This case indicates that radiotherapy may offer a benefit to PAL patients, particularly those who do not respond to chemotherapy.
