Summary
Unplanned excision of soft tissue sarcoma (STS) leads to poor prognosis. Local recurrence and high tumor grade are key indicators of adverse outcomes, necessitating prompt specialist referral for better patient management.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Unplanned excision (UE) of soft tissue sarcoma (STS) significantly impacts patient prognosis and recurrence rates.
- Limited comprehensive analyses exist for STS patients undergoing UE.
Purpose of the Study:
- To comprehensively evaluate prognostic factors in patients with STS who underwent unplanned excision.
- To identify key predictors of survival and recurrence in this patient cohort.
Main Methods:
- Retrospective identification of 62 STS patients who underwent UE.
- Evaluation of clinical data for risk factors associated with overall survival, local recurrence, and distant metastases.
- Statistical analysis including multivariate analysis and Kaplan-Meier curves.
Main Results:
- Consultation after local recurrence and high histological grade were significant predictors of poor prognosis (p=0.0390, p=0.0282).
- High histological grade was the sole risk factor for distant metastasis (p=0.0173).
- Kaplan-Meier analysis showed significant differences in overall survival based on local recurrence at referral (p=0.0476, p=0.0022).
Conclusions:
- Referral after local recurrence and high histological grade are identified as poor prognostic factors for STS patients undergoing UE.
- Emphasizes the critical need for prompt referral of UE patients to specialists to improve outcomes.
