OBJECTIVES:
Comparative Study Between Methylene Blue And Isosulfan Blue Dye For Detection Of Sentinel lymph Node In Operable Breast Carcinoma
METHODS:
A controlled randomized trial is carried out on thirty female patients suffering from operable breast cancer ( stage I & II ); patients were divided into two groups:
Group I : Fifteen patients were injected by methylene blue dye at the subareolar region . Group II : Fifteen patients were injected by patent blue dye at the subareolar region .
All patients were subjected to:
Full history taking .
Meticulous clinical examination, including both axillae for any clinicaly palapable lymph nodes.
Routine laboratory investigations .
Mammogaphy
Abdominal ultrasongraphy
RESULTS:
The age distribution in the present series ranged between 24 and 65 years with a mean of 45.2 years.
The commonest affected site was the upper outer quadrant (53.4%).
The tumor size varied between 0.5 and less than 5 cm in its greatest dimension.
29.4% of patients with palpable movable axillary nodes proved to be node negative following ALND and 15.4% of clinically node negative patients had metastatic nodal involvement.
SLN was successfully idenfied in 93.3% of cases.
SLN identification rate in group I (methylene blue injection) was 93.3%.
SLN idenitification rate in group II (patent blue injection) was 93.3%.
SLN was commonly located at level I (92.85%).
Skip metastasis was found in 7.15% of cases.
CONCLUSIONS:
The sensitivity of lymphatic mapping in the study was 100%.
The positive SLN predicted the positive axillary basin in 100% cases, also negative SLN predicted the negative axillary basin in 100% of cases.
