Hypothesis
Is submucosal or subserosal injection more effective for sentinel node detection in gastric cancer?
Conclusion
The tracer injection sites do not have to be limited to the submucosa.
Supporting Evidence
- The study involved 63 consecutive patients with gastric cancer.
- Both injection methods showed no significant differences in detection rates.
- The sensitivity of metastatic detection was 86% for submucosal and 100% for subserosal injection.
Takeaway
Doctors can inject a special dye either inside or outside the stomach to find important lymph nodes in stomach cancer, and both methods work similarly.
Methodology
The study involved 63 patients with gastric cancer who received either submucosal or subserosal injections of tracers to compare detection rates.
Limitations
The study had a small number of patients with metastatic lymph nodes, which may affect the statistical significance of the results.
Participant Demographics
Patients with early gastric cancer (sT1–T2, sN0, tumor diameter ≦ 4 cm).
