Summary
Surgeons know positive resection lines harm survival, yet inadequate gastric cancer resections persist. This study highlights the need for better intraoperative margin assessment to improve patient outcomes.
Area of Science:
- Surgical Oncology
- Gastrointestinal Surgery
- Cancer Research
Background:
- Resection-line disease negatively impacts anastomotic leakage, perioperative mortality, and long-term survival in gastric cancer surgery.
- Despite awareness of these adverse effects, the impact on surgical practice remains unclear.
Purpose of the Study:
- To assess the effect of surgeon knowledge regarding resection-line disease on surgical practice in gastric cancer.
- To evaluate the correlation between resection-line involvement and patient survival outcomes.
Main Methods:
- Analysis of patient data from the second British Stomach Cancer Group adjuvant therapy trial.
- Comparison of resection-line disease presence with operative stage in 555 patients.
- Survival analysis based on resection-line status and disease stage.
Main Results:
- Resection-line disease was present in 19% of patients (105/555).
- Inadequate resections occurred in 13% of potentially curative operations (55/424).
- Five-year survival was significantly lower for patients with resection-line involvement (9%) compared to those with clear margins (27%) for Stage I-III disease.
Conclusions:
- Surgeons continue to perform inadequate gastric cancer resections despite awareness of adverse outcomes associated with positive resection lines.
- There is a critical need for a more aggressive approach to assessing resection margins during surgery to improve patient survival.
