Is early dynamic lymphoscintigraphy for detection of sentinel lymph nodes always achievable in breast tumor?
OBJECTIVE: In this article, we will discuss the achievement of early dynamic lymphoscintigraphic protocol and compare detection of sentinel node between benign and malignant breast tumors, and whether pathologic factor is related or not. METHODS: During a six-month period, consecutive fifty-nine patients were enrolled into our study. The average age of patients was 47.6 +/- 9.8 years and all of them were clinically suspected of having breast cancer. The average tumor was 2.1 +/- 1.1 cm in size. First, Tc-99m sulfur colloid was injected around corners of palpable mass or biopsy cavity by the hybrid injection method. Immediately thereafter, dynamic protocol of lymphoscintigraphy, with 10 sec per frame for 60 frames was performed by established simultaneous dual-head vertical angle imaging technique. And delayed two-hour image was also acquired. All patients underwent surgery sixteen to twenty hours later and had a final pathological diagnosis. RESULTS: Among 59 patients, 14 of them were
