Summary
Sentinel lymph node (SLN) mapping using Patent Blue V dye is a quick, cost-effective, and highly sensitive method for accurate nodal staging in colorectal cancer patients. This technique improves staging accuracy and can alter surgical management by identifying occult micrometastases.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Colorectal cancer is a significant gastrointestinal malignancy.
- Radical lymphadenectomy is the standard for metastatic nodal disease.
- Pathological understaging due to micrometastases affects 15-30% of early-stage patients.
Purpose of the Study:
- To present and analyze experience with sentinel lymph node (SLN) mapping in colorectal cancer.
- To describe the applied dye-method for SLN identification.
Main Methods:
- Utilized the dye-method with Patent Blue V for SLN mapping.
- Applied to patients with verified colorectal cancer.
Main Results:
- SLN mapping with Patent Blue V is simple, quick (5-10 min), and cost-effective.
- Achieved 100% success rate and 92% sensitivity.
- SN status predicted regional lymph node status in 67% of patients, with 8% false-negative rate.
- Upstaged 4% of patients from Stage II to III and altered surgery in 4% due to positive SNs.
Conclusions:
- SLN mapping is a feasible and effective tool for accurate nodal staging in colorectal cancer.
- It enhances diagnostic possibilities and can guide surgical decisions.
- The technique is technically simple and quick for surgeons.
