We present a case of metastatic pleuropulmonary LMS managed with a novel combined approach: robotic-assisted cytoreductive surgery and hyperthermic intrathoracic chemotherapy (HITHOC) . A 61-year-old male with high-grade LMS developed progressive pleural and pulmonary metastases following prior systemic chemotherapy and palliative radiotherapy. Diagnostic imaging showed enlarging pleural nodules and diaphragmatic thickening, with PET-CT confirming intense hypermetabolic activity confined to the right hemithorax. A multistep robotic-assisted thoracic procedure was performed, including total pleurectomy, pulmonary segmentectomy, mediastinal lymphadenectomy, and HITHOC utilizing cisplatin at 42°C. The patient achieved an uncomplicated postoperative course and reported complete symptomatic relief of pre-existing pleuritic pain. At 6-months postprocedure, follow-up imaging confirmed isolated local recurrence (two subpleural nodules) . However, no regional lymphadenopathy or distant progression was detected. The patient was transitioned to pazopanib therapy, which resulted in radiological stability and maintained symptomatic control through the 12-month postoperative follow-up period. This case demonstrates the feasibility, safety, and therapeutic value of robotic cytoreduction with HITHOC in selected metastatic LMS, achieving complete macroscopic resection and sustained 12-month disease control when integrated with targeted therapy.  \nKeywords: HITHOC; hyperthermic intrathoracic chemotherapy; leiomyosarcoma; pleural metastases; robotic surgery; thoracic oncology  \n1. Introduction  \nLeiomyosarcoma (LMS) is a malignant tumor of mesenchymal origin with high metastatic potential, frequently disseminating to the lungs and pleura. Although systemic chemotherapy remains the mainstay for advanced LMS, durable disease control is rarely achieved [1] . In selected patients with oligometastatic or localized progressive dis-  \nease, aggressive local treatment can provide meaningful  \nsymptom relief and improved locoregional control [2] .  \nRobotic-assisted thoracic surgery (RATS) has markedly advanced the execution of complex thoracic oncology procedures. Its enhanced dexterity and three-dimensional visualization enable precise cytoreduction in anatomically challenging pleural regions. These technical advantages translate into reduced postoperative pain and faster  \n2 Case Reports in Oncological Medicine  \nFigure 1: Preoperative PET-CT demonstrated increased 18F-F","cbCaigq9tz5MJQfQ","https://ap.wps.com/l/cbCaigq9tz5MJQfQ","pdf",1246780,"English","# Introduction\n# Case Presentation","[{\"question\":\"What procedure combination was used in the reported metastatic pleuropulmonary LMS case?\",\"answer\":\"The patient was treated with robotic-assisted cytoreductive surgery combined with hyperthermic intrathoracic chemotherapy (HITHOC).
