Highlights ■ De-escalation of axillary surgery has become a priority in  breast cancer treatment. ■ Factors associated with the decision to omit sentinel lymph node biopsy were collected via questionnaire. ■ Sentinel lymph node biopsy was omitted more often by  private doctors and those holding a doctoral degree. ■ Continuing medical education initiatives are needed to update other groups. ABSTRACT Objective: Considering the increasing number of new breast cancer cases and the morbidity associated with axillary lymph node dissection in […]

ABSTRACT Objective: To assess data on survival, recurrence and histological factors in positive and negative sentinel lymph nodes in thin melanoma cases. Methods: A systematic review was conducted on observational studies in four databases (Cochrane Library, Medline, Embase and Lilacs). Positive and negative micrometastases in sentinel lymph node biopsy were compared regarding the clinical outcomes – death and recurrence – and six histological factors – vertical growth phase, Breslow thickness, Clark level, ulceration, regression and mitosis rate. Results: Positive sentinel […]
