[Successful Treatment of Estrogen Receptor Positive, HER2 Negative Breast Cancer with Life-Threatening Multiple Bone Metastases Using the Combination of Fulvestrant and Palbociclib-A Case Report].

Palbociclib, a CDK4/6 inhibitor, is found to be an effective therapeutic drug in the treatment of estrogen receptor positive (ER+)metastatic breast cancer. In this report, we describe a case of rapid progression of life-threatening multiple bone metastases of breast cancer treated with a combination of fulvestrant and palbociclib. The patient, a 58-year-old postmenopausal woman, was diagnosed with left breast cancer at the age of 43 years and underwent breast-conserving surgery.

[A Case of Breast Mucinous Carcinoma with Bladder Metastasis Effectively Treated with Endocrine Therapy and Chemotherapy].

A 57-year-old Japanese woman underwent partial mastectomy of the right breast and sentinel lymph node biopsy in July 2005. The diagnosis was mucinous carcinoma with negative margins and no lymph node metastases(pT1cN0M0, pStage Ⅰ A). Postoperative adjuvant therapy included radiation therapy and oral administration of anastrozole for 5 years.

Vascular endothelial growth factor receptor 1 (VEGFR1) tyrosine kinase signaling facilitates granulation tissue formation with recruitment of VEGFR1 cells from bone marrow.

Vascular endothelial growth factor (VEGF)-A facilitates wound healing. VEGF-A binds to VEGF receptor 1 (VEGFR1) and VEGFR2 and induces wound healing through the receptor's tyrosine kinase (TK) domain. During blood flow recovery and lung regeneration, expression of VEGFR1 is elevated.

Vascular endothelial growth factor receptor-1 (VEGFR-1) signaling enhances angiogenesis in a surgical sponge model.

Background: Vascular endothelial growth factor (VEGF)-A binds to both VEGF receptor (VEGFR)-1 and VEGFR-2, thereby promoting angiogenesis. It is widely accepted that VEGF-A, especially VEGFR-2, is a central player in angiogenesis, however the role of VEGFR-1 in angiogenesis remains unclear. The present study was conducted to examine the role of VEGFR-1 signaling in angiogenesis, using a quantitative in vivo angiogenesis model.

Single-stage reconstruction of a full-thickness alar defect using a folded nasolabial flap combined with a redundant skin turnover flap.

Background: The reconstructive strategy for full-thickness nasal skin defects should include recreation of a cutaneous cover, support, and internal nasal lining. The most challenging aspect of this procedure is provision of the nasal lining. These reconstructions typically require a 2-step process.
