Simultaneous bilateral video-assisted thoracoscopic surgery (VATS) for pulmonary metastases of uterine leiomyosarcoma

Abstract

We report two cases of bilateral metastatic lung tumors of uterine leiomyosarcoma. (Case 1) In 1987, a 59-year-old woman underwent hysterectomy and was given a diagnosis of uterine leiomyosarcoma. In 1991, nodules in her right lung were pointed out. In 2002, following her consent, we performed VATS involving a right lower lobectomy and wedge resection of the right S2 and S3, and left S3 and S6. The seven tumors excised were verified to be lung metastases of uterine leiomyosarcoma. No evidence of recurrence was found during the 6-year postoperative follow-up period. (Case 2) A 47-year-old woman underwent hysterectomy with left oophorectomy. The lesion was diagnosed as leiomyosarcoma of the uterus. A chest CT taken 6 months after resection revealed multiple pulmonary nodules. She underwent VATS involving wedge resection of the right middle and lower lobes, and left upper and lower lobes. Two nodules were diagnosed as lung metastases of uterine leiomyosarcoma. There has been no sign of recurrence for 1 year since the operation. Simultaneous bilateral VATS for pulmonary metastases of uterine leiomyosarcoma is one of the effective treatment options.
