Evaluation of the efficacy of using indocyanine green associated with fluorescence in sentinel lymph node biopsy.

Introduction: Sentinel lymph node biopsy is the technique recommended for the axillary staging of patients with breast cancer in the initial stages without clinical axillary involvement. Three techniques are widely used globally to detect sentinel lymph nodes: patent blue, the radiopharmaceutical technetium 99 with gamma probe, and the combination of these two.

Objectives: To evaluate the sentinel lymph node detection rate with an innovative technique: indocyanine green (ICG) associated with fluorescence in breast cancer patients, and compare it with patent blue and a combination of patent blue and indocyanine green.

[Gastrointestinal stromal tumor: a report of eight cases].

Introduction: Diagnosis and treatment of Gastrointestinal Stromal Tumor have changed because of recent genetic and molecular biological studies which have a direct impact on longer survival.

Methods: A retrospective research was carried out from November 1998 to July 2004 at the university and in the private clinics of the authors who identified GIST cases based upon positive tests to c-kit (CD117).

Results: The eight patients that were evaluated had an average age of 53.
