Successful resection and adjuvant radiation therapy for inferior vena cava leiomyosarcoma can lead to long-term disease-free survival and symptom resolution.
May support resection plus radiation in select IVC leiomyosarcoma cases; leaves open need for cohort validation before broader adoption.
A 68-year-old white female presented with two years of progressively worsening dyspnea. Echocardiography revealed a large right atrial mass and partial obstruction of the inferior vena cava. Further imaging revealed a cystic dense mass in the inferior vena cava and right atrium. Immunohistochemical stains were consistent with leiomyosarcoma. Intraoperatively, the tumor was noted to originate from the posterior aspect of the inferior vena cava. The patient underwent successful resection of the mass. Adjuvant radiation therapy was completed. The patient's dyspnea gradually improved and she continues to remain disease free five years post-resection.
