We have retrospectively examined a wide range of clinical characteristics, sonographic features, microbiology, and antibiotic regimens in patients with breast abscesses to seek predictive features related to outcome. Because consensus for optimal treatment of breast abscesses has moved toward minimally invasive management using single or repeated needle aspiration (ASP) coupled with adjuvant antibiotics, we assessed whether any factors correlate with the need for repeat procedures by analyzing the number of ASPs and/or surgical incision and drainage (I&D) per abscess. We examined 127 abscesses in 114 patients from a single urban public hospital, and among clinical characteristics, we found that only smoking history (P = .021) and the presence of nipple rings (P = .005) were associated with greater likelihood of necessitating repeat for abscess resolution procedures. ⋯ Likewise, no specific micro-organisms predicted a greater likelihood of requiring repeat procedures, and no specific initial antibiotic regimen (gram-positive and/or gram-negative or multiresistance coverage) impacted clinical outcomes. Our data indicate that no specific imaging abscess characteristics, type of micro-organism, or initial choice of antibiotics affect outcomes, and therefore, these features should not preclude attempts at conventional therapy by repeated aspiration and antibiotic treatment. While a smoking history and presence of a nipple ring may increase the risk of a prolonged course, the decision to change antibiotics or repeat aspiration should rely instead on clinical evaluation and judgment by experienced physicians.

According to the current guidelines on treatment of breast cancer patients, identification of metastases in the sentinel lymph node (SLN (+)) is not an absolute indication for necessary axillary lymph node dissection (ALND). In our study, we present long-term outcomes of treatment among SLN(+) patients referred for conservative treatment, for example, no further ALND. A total of 3145 breast cancer patients subjected to sentinel lymph node biopsy (SLNB) between November 2008 and June 2015. ⋯ Lack of radical surgical treatment in SLN(+) breast cancer patients did not lead to worsening long-term outcomes. In the occurrence of macrometastases to the sentinel lymph node, abandoning completion axillary lymph node dissection might be a reasonable option. However, it would require continuation of current research, preferably involving a clinical trial.
