TO THE EDITOR: In their very interesting article on mammary lymphoscintigraphy, Valdés Olmos et al. (1) report on applying a single intratumoral injection for sentinel lymph node (SLN) identification. Only patients with an operable, palpable breast tumor were included in the study. The authors used 99mTclabeled nanocolloid with a particle size of ,80 nm. During the first 30 min, two to eight no...

BACKGROUND Omitting extensive lymph node dissection could reduce esophagectomy morbidity in patients without lymph node metastases. Sentinel node biopsy may identify abdominal or thoracic lymph node metastases, thereby differentiating treatment. Feasibility of this approach was investigated in Western European esophageal cancer patients with advanced disease, without lymph node metastases at di...

INTRODUCTION In the case of clinically negative inguinal regions in penile cancer, the treatments proposed might vary from careful observation to radical dissection for all patients. We evaluated the effectiveness of the sentinel lymph node biopsy using lymphoscintigraphy in patients with penile cancer and at least one negative inguinal region. MATERIALS AND METHODS In 18 patients, biopsy of ...

PURPOSE: Head and neck melanoma is associated with a high false negative sentinel lymph node biopsy (SLNB) rate. Our group previously demonstrated the combination of radiotracer and ICG SPY Elite navigation system was feasible and more sensitive compared to standard vital dye and radioactive tracer for SLNB. The goal of this report was to analyze our experiences utilizing ICG fluorescence with ...

The aim of this study was to describe a new variation of the technique to evaluate lymph drainage utilizing lymphoscintigraphy. A LS scan marks the route of lymphatic vessels and may be used to assess both manual lymph drainage and lymph drainage after using some apparatuses. This evaluation may be dynamic, collecting images whilst performing lymph drainage or static, with scans before and afte...
