The purpose of this study is to obtain a consensus for the therapy of B3 lesions. The first International Consensus Conference on lesions of uncertain malignant potential in the breast (B3 lesions) including atypical ductal hyperplasia (ADH), flat epithelial atypia (FEA), classical lobular neoplasia (LN), papillary lesions (PL), benign phyllodes tumors (PT), and radial scars (RS) took place in January 2016 in Zurich, Switzerland organized by the International Breast Ultrasound School and the Swiss Minimally Invasive Breast Biopsy group—a subgroup of the Swiss Society of Senology. Consensus recommendations for the management and follow-up surveillance of these B3 lesions were developed and areas of research priorities were identified. The consensus recommendation for FEA, LN, PL, and RS diagnosed on core needle biopsy or vacuum-assisted biopsy (VAB) is to therapeutically excise the lesion seen on imaging by VAB and no longer by open surgery, with follow-up surveillance imaging for 5 years. The consensus recommendation for ADH and PT is, with some exceptions, therapeutic first-line open surgical excision. Minimally invasive management of selected B3 lesions with therapeutic VAB is acceptable as an alternative to first-line surgical excision.

Pretreatment circulating NRP levels predict a low likelihood of benefit from HT, specifically DRO, in patients with estrogen receptor (ER)-positive and/or progesterone receptor (PgR)-positive or receptor-unknown metastatic breast cancer, even when adjusted for other known predictive factors, such as ER and/or PgR levels, site of disease, disease-free interval from primary treatment to recurrence, and prior adjuvant chemotherapy. These data suggest that pretreatment NRP levels may be useful in deciding whether to treat a patient who otherwise appears to be likely to respond to HT.

Organ transplantation is associated with a high turnover of bone metabolism, and an increased loss of bone mass and incidence of osteoporotic fractures. Established therapies for osteoporosis after organ transplantation are still lacking, however. We report on an intravenous bisphosphonate therapy initiated in transplant patients because of a high rate of bone loss or incident osteoporotic fractures. Twenty-one patients after liver transplantation and 13 patients after heart transplantation received 30 mg pamidronate intravenously every 3 months, combined with 1000 mg calcium and 1000 IU vitamin D per day. The median time interval between transplantation and start of pamidronate treatment was 1.9 years in cardiac patients and 2.3 years in liver patients. Lumbar spine bone mineral density (LS BMD) and femoral neck BMD (FN BMD) were measured before and every 6 months after pamidronate therapy was initiated. Spinal radiographs were performed annually. Biochemical markers of bone metabolism were determined every 3 months, immediately before pamidronate administration. From a previous observational study, 58 patients treated only with calcium and vitamin D were matched for age, sex, pretransplantation LS BMD and time interval between transplantation and the first pamidronate treatment. In the pamidronate-treated patients, the mean increase in LS BMD adjusted for baseline values amounted to 0.080 +/- 0.038 g/cm(2) (8.6 +/- 4.0 %) after 1 year and 0.091 +/- 0.058 g/cm(2) (10.4 +/- 6.1%) after 2 years compared with 0.001 +/- 0.037 g/cm(2) (0.26 +/- 4.0%) after 1 year and 0.015 +/- 0.057 g/cm(2) (1.8 +/- 6.0%) after 2 years in the historical control group (absolute LS BMD changes pamidronate group vs historical group p < 0.0001 after 1 and 2 years). The changes of FN BMD were 0.024 +/- 0.043 g/cm(2) (3.2 +/- 6.1%) after 1 year and 0.046 +/- 0.052 g/cm(2) (7.0 +/- 6.1%) after 2 years in the pamidronate group compared with -0.012 +/- 0.043 g/cm(2) (-1.6 +/- 6.1%) after 1 year and -0.013 +/- 0.052 g/cm(2) (-1.1 +/- 6.1%) after 2 years in the historical control group (absolute FN BMD changes pamidronate group vs historical group p = 0.003 after 1 year and p = 0.001 after 2 years). From a total of 287 application cycles of pamidronate treatment, no severe side effects were observed and non-severe side effects were seen in only 39 cycles (13.6%). We conclude that cyclic intravenous pamidronate treatment is beneficial to patients with low bone mass or osteoporotic fractures following transplant, even when not immediately initiated.
