Surgical Outcomes and Risk Analysis of Primary Pulmonary Sarcoma.

Area of Science:

• Oncology
• Thoracic Surgery
• Pulmonary Medicine

Background:

• Primary pulmonary sarcoma (PPS) is a rare lung malignancy with limited treatment data.
• This study aimed to define clinical characteristics and outcomes of surgically treated PPS patients.

Observation:

• 24 patients with PPS underwent surgical resection (pneumonectomy, lobectomy, wedge resection) between 1995-2014.
• Complete resection was achieved in 16 patients.
• Pathological stages ranged from I to IV, with 4 cases of lymph node metastasis.

Findings:

• The 5-year overall survival rate for PPS patients was 50%.
• Adverse prognostic factors identified were incomplete resection, advanced pathological stage, higher pathological grade, and tumor size ≥ 7 cm.

Implications:

• Surgical complete resection is crucial for improving long-term survival in primary pulmonary sarcoma.
• Tumor size, stage, and grade are critical indicators for prognosis in PPS patients.
