Tc-Tilmanocept Versus Tc-Sulfur Colloid in Lymphoscintigraphy: Sentinel Lymph Node Identification and Patient-Reported Pain.

Lymphoscintigraphy plays a vital role in sentinel lymph node (SLN) identification in oncologic breast surgery. The effectiveness of SLN localization and the degree of patient pain were compared between filtered Tc-sulfur colloid (Tc-SC) and Tc-tilmanocept. A retrospective review of patients undergoing lymphoscintigraphy for breast cancer using Tc-SC (June 1, 2010, to December 31, 2011) or Tc-tilmanocept (June 1, 2013, to January 31, 2014) was performed.

Effect of patient age, breast density, and topical anesthetic cream on perceived pain with sentinel lymph node scintigraphy.

Unlabelled: Although an extremely useful technique for sentinel lymph node (SLN) identification in breast cancer, injections of (99m)Tc-sulfur colloid can be quite painful. The purpose of this study was to determine whether there is a correlation between perceived pain of injection and age, breast density, or timing of topical anesthetic cream administration.

Methods: A retrospective review was conducted of women with breast cancer who received injections for sentinel lymphoscintigraphy from 2008 to 2010.
