BACKGROUND: We examined the effects of recombinant human osteoclastogenesis inhibitory factor (hOCIF) on osteolysis, proliferation of mammary tumor cells, and induction of cancer stem cells (CSCs) in the tumor-bone and tumor-subcutaneous microenvironments (TB- and TS-microE). METHODS: Mouse mammary tumor cells were transplanted onto the calvaria or into a subcutaneous lesion of female mice, creating a TB-microE and a TS-microE, and the mice were then treated with hOCIF...

BACKGROUND: Implant rippling is a frequent complication following breast augmentation or implant-based reconstruction and results in significant patient dissatisfaction. Traditionally, the treatment has been to replace the implant, often placing it in a subpectoral pocket to reduce the risk of recurrence. Other techniques, such as increasing the implant size or tightening the capsule, can also be used. Recently, however, there has been much interest in alternative treatments, including fat grafting or insertion of an acellular dermal matrix...

The "ovarian cycle" is an exquisite and dynamic endocrine system that includes ovarian events, hypothalamic-pituitary interactions, uterine endometrial and myometrial changes during implantation and pregnancy, cervical alterations in structure, and breast development. The ovarian cycle and the steroid hormones produced by the ovary also impact epithelial cancer development in the ovary, uterus, cervix, and breast. This chapter provides a personal view of recent developments that occur in this complex endocrine environment...

BACKGROUND: Ketorolac tromethamine (Toradol) is an effective a nonsteroidal anti-inflammatory drug and a powerful analgesic for patients undergoing breast surgery. However, the potential for postoperative bleeding has not yet been explored specifically in women undergoing implant-based breast reconstruction. There is concern that an increased risk of bleeding exists in this population due to the lack of tissue apposition as a result of implant placement. We therefore seek to assess the associated risk of bleeding complication in implant-based breast reconstruction at our academic institution...

BACKGROUND: Infection is the most significant complication in implant-based breast reconstruction, potentially leading to reconstructive failure. We hypothesized that implementation of an evidence-based protocol marked by preoperative decolonization and sterility optimization would result in a decline in postoperative infection rates. METHODS: Informed by a literature review, we developed an evidence-based, perioperative infection prevention protocol implemented in 2015...

AIMS: Reconstruction of breasts and chest wall deformities in female patients after severe burn injury is a challenge for reconstructive surgeons. In these patients, neither implant-based procedures nor standard free flaps are sometimes applicable because of limited skin quality and unavailability of donor sites at the abdomen, back, buttock, or medial thigh. METHODS: We present a case of a young female patient with a history of 80 % total body surface area burn after electric high-voltage injury...

Currently, there are very few therapeutic options for treatment of metastatic disease, as it often remains undetected until the burden of disease is too high. Microporous poly(ε-caprolactone) biomaterials have been shown to attract metastasizing breast cancer cells in vivo early in tumor progression. In order to enhance the therapeutic potential of these scaffolds, they were modified such that infiltrating cells could be eliminated with non-invasive focal hyperthermia. Metal disks were incorporated into poly(ε-caprolactone) scaffolds to generate heat through electromagnetic induction by an oscillating magnetic field within a radiofrequency coil...

INTRODUCTION AND AIM: To report the clinical outcomes of second breast-conserving therapy with perioperative interstitial radiotherapy for the treatment of ipsilateral breast tumor recurrences. METHOD: Between 1999 and 2015, 33 patients, presenting with an ipsilateral breast tumor recurrence after previous breast conserving therapy, were salvaged by re-excision and perioperative high-dose-rate interstitial brachytherapy. A median of 8 (range: 4-24) catheters were implanted into the tumor bed intraoperatively...

We present a 41-year-old woman with itching polymorphic skin lesions involving the trunk and extremities which first appeared in September 2011 (7 years ago). Physical examination revealed multiple erythematous, scaly macules and patches, indurated red plaques and purplish red and smooth surfaced nodules (Fig. 1a). Over the period of seven years, the skin lesions grew slowly and spread across the body but sometimes they regressed either spontaneously or after insolation.

Sphingosine-1-phosphate (S1P), a bioactive sphingolipid mediator, has been implicated in regulation of many processes important for breast cancer progression. Previously we observed that S1P is exported out of human breast cancer cells by ATP-binding cassette (ABC) transporter ABCC1, but not by ABCB1, both known multidrug resistance proteins that efflux chemotherapeutic agents. However, the pathological consequences of these events to breast cancer progression and metastasis has not been elucidated. Here, it is demonstrated that high expression of ABCC1, but not ABCB1, is associated with poor prognosis in breast cancer patients...

As the availability of breast reconstruction using implants is becoming widespread and many implant recipients undergo radiation therapy, there is an increasing interest in understanding the potential complications associated with capsule-tissue interactions in response to irradiation. Accordingly, our medical institution designed an animal experiment to investigate the effects of irradiation on capsular contracture. A total of 40 mice (C57BL6) were divided into four groups according to whether or not they received irradiation and the time from implantation to irradiation...

BACKGROUND: Contralateral risk-reducing mastectomy (CRRM) for breast cancer patients with BRCA mutations has been reported to not only reduce breast cancer incidence but also to improve survival. The National Comprehensive Cancer Network guidelines recommend providing CRRM to women with BRCA mutations who desire CRRM after risk-reduction counseling. However, in Japan, CRRM cannot be performed generally because it is not covered by health insurance. Thus, we conducted a feasibility study to confirm the safety of CRRM...

PURPOSE: Magnetic resonance imaging has been used extensively to track in vivo implanted cells that have been previously labeled with relaxation enhancers. However, this approach is not suitable to track multiple cell populations, as it may lead to confounding results in case the contrast agent is released from the labeled cells. This paper demonstrates how the use of CEST agents can overcome these issues. After encapsulating paramagnetic lanthanide shift reagents, we may shift the absorption frequency of the intracellular water resonance (δIn ), thus generating frequency-encoding CEST responsive cells that can be visualized in the MR image by applying the proper RF irradiation...

PURPOSE OF REVIEW: Given the rarity of anaplastic large cell lymphoma (ALCL), studies evaluating new therapies have typically grouped ALCL together with other peripheral T cell lymphomas (PTCL). Thus, the treatment paradigm for ALCL largely mirrors that of PTCL in general. In this review, we discuss the current standard of care as well as emerging therapies, including antibody-based drugs, in systemic ALCL as well as primary cutaneous and breast implant-associated ALCL. RECENT FINDINGS: High CD30 expression in ALCL has allowed the use of brentuximab vedotin, an anti-CD30 antibody-drug conjugate, in both systemic and primary cutaneous ALCL...

BACKGROUND: Tumor hypoxia is an independent prognostic factor associated with poor patient survival. Emerging evidence suggests that hypoxia can potentially maintain or enhance the stem cell phenotype of both normal stem cells and cancer cells. However, it remains to be determined whether cell fate is regulated in vivo by the hypoxic tumor microenvironment (TME). METHODS: We established a hypoxia-sensing xenograft model to identify hypoxic tumor cell in vivo primarily using human breast cancer cell lines MDA-MB-231 and MCF7...

BACKGROUND:  Increased rates of both breast cancer and obesity have resulted in more obese women seeking breast reconstruction. Studies demonstrate that these women are at increased risk for perioperative complications. A systematic review was conducted to assess the outcomes in obese women who underwent breast reconstruction following mastectomy. METHODS:  Cochrane, PUBMED, and EMBASE electronic databases were screened and data were extracted from included studies...

AIM OF THE STUDY: Immediate breast reconstruction is often applied after mastectomy. However, inappropriate surgical technique, postoperative radiotherapy and infection may lead to tissue necrosis and implant protrusion. Traditional therapies frequently fail. However, previous data suggested that capsule flaps may be appropriate for the salvage of implants. Our goal was to investigate the usefulness of capsuloplasty in patients with exposed breast implant and to monitor the blood supply of capsule flaps during the operation...

BACKGROUND: Survey-based research is essential for evaluating the outcomes of health care in an era of patient-centered care. However, many such studies are hampered by poor response rates in completion of study questionnaires, thus limiting the generalizability of any findings. The objectives of this analysis were to identify independent variables associated with nonresponse to surveys following breast reconstruction to improve future patient-reported outcomes research. MATERIALS AND METHODS: The Mastectomy Reconstruction Outcomes Consortium is a prospective cohort study involving 11 leading medical centers from the United States and Canada...
