- STAS in colorectal lung metastases is associated with worse recurrence-free and overall survival, particularly intrathoracic recurrence.
- Quantitative STAS metrics like density and spread distance correlate with intrathoracic recurrence risk.
- High tumor budding grade in the primary tumor is linked to higher STAS presence and serves as a preoperative marker.
