Durable Disease Control in Primary Pulmonary Sarcomatoid Carcinoma Following Pneumonectomy

Area of Science:

• Oncology
• Thoracic Surgery
• Radiology

Background:

• Primary pulmonary sarcomas are rare lung malignancies with nonspecific symptoms, often leading to late diagnosis.
• Sarcomatoid carcinoma is an aggressive subtype of primary pulmonary sarcoma.
• Vascular invasion presents a significant challenge in surgical management.

Purpose of the Study:

• To report a case of primary pulmonary sarcomatoid carcinoma with extensive vascular invasion.
• To highlight the importance of multidisciplinary management and aggressive surgical intervention.
• To demonstrate the potential for long-term disease control in rare pulmonary sarcomas.

Main Methods:

• Diagnostic imaging (CT) and biopsy for definitive diagnosis.
• Preoperative bronchial artery embolization to manage vascular involvement.
• Left pneumonectomy with pulmonary arterioplasty via median sternotomy for tumor resection.
• Postoperative follow-up with serial imaging.

Main Results:

• A 26-year-old male diagnosed with primary pulmonary sarcomatoid carcinoma.
• Successful surgical resection achieved despite significant vascular invasion.
• Uneventful postoperative recovery and no evidence of recurrence at two-year follow-up.

Conclusions:

• Timely diagnosis and aggressive surgical management are crucial for rare and aggressive lung malignancies like sarcomatoid carcinoma.
• Multidisciplinary planning is essential for optimizing outcomes in complex thoracic oncology cases.
• Complete resection, even with vascular invasion, can lead to favorable long-term prognosis.
