N-acetylcysteine (NAC) is used to treat Tylenol toxicity. NAC is a rich source of the sulfhydryl group (SH) which is important for replenishing the body's glutathione stores. Glutathione acts as a free radical scavenger, to decrease the damage that would be caused by those toxic radicals. Patients who undergo orthotopic liver transplantation (OLT) have a high incidence of post-operative renal dysfunction. The most common etiology of post-operative renal dysfunction is related to high levels of toxic free radicals. Free radicals may contribute to primary liver graft failure or delayed liver graft function. Specific Aims \& Objectives: The primary objective of this study is to evaluate the efficacy of NAC in improving liver graft performance and lowering the incidence of post-operative renal dysfunction. The secondary objectives are to investigate the effect of NAC on endogenous glutathione body stores and its effect on FK506 induced toxicity.

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This phase II trial is studying surgery to remove the sentinel lymph node and axillary lymph nodes after chemotherapy in treating women with stage II, stage IIIA, or stage IIIB breast cancer.
