Summary

Patients with breast cancer scheduled to undergo sentinel lymph node mapping and biopsy will be randomly assigned to one of four treatment groups: I: (Standard of Care at WRAMC): Application of L-M-X topical anesthetic cream 4% to the breast within one hour of sub-areaolar injection of 4 ml 99mTc-sulfur colloid (1 mCi in normal saline) II. Sub-areolar injection of 4 ml pH-adjusted 99mTc-sulfur colloid (1 mCi in sodium bicarbonate) III. Sub-areolar injection of 4 ml pH-adjusted 99mTc-sulfur colloid (1 mCi in 1% Lidocaine) IV. Sub-areolar injection of 4 ml pH-adjusted 99mTc-sulfur colloid (1 mCi in sodium bicarbonate + 1% Lidocaine) The primary study outcome is pain, which will be evaluated for each study group before, and after radiocolloid injection utilizing a standardized 10-point Likert scale, the Wong-Baker FACES Pain Rating Scale, and the McGill Pain Questionnaire. Physician appraisal of patient pain (Wong-Baker FACES Pain Rating Scale) will be estimated during the radiocolloid injection and compared with that of the patient.

Detailed description

Null hypothesis: There is no difference in overall pain intensity between standard and pH adjusted radiocolloid for patients undergoing sentinel lymph node mapping and biopsy for breast cancer. Objectives and scientific aims: To compare the intensity of pain (Wong-Baker FACES Pain Rating Scale + McGill Pain Questionnaire) associated with WRAMC's current standard and pH-adjusted radiocolloid for patients undergoing sentinel lymph node mapping and biopsy for breast cancer. To assess objectively physician appraisal of patient pain during the radiocolloid injection and compare physician interpreted pain score with patient reported pain score. Define the success rate of intra-operative SLN identification for each study group.
