Perioperative Decision-Making for a Solitary Fibrous Tumor of the Pleura: Lessons from Two Cases and Current Evidence

These two cases illustrate the feasibility of en bloc R0 resection in operable SFTP, despite interval growth observed in Case 2. Combined with literature evidence, early en bloc R0 resection appears to be preferable to prolonged observation for operable SFTP, balancing the risks of unpredictable growth, malignant transformation, and recurrence-even in histologically benign tumors (up to 6.3%)-against potential surgical morbidity. Tailored preoperative planning appears beneficial, complemented by pathology-based risk models for postoperative stratification and risk-adapted surveillance.
