Hypoxia-induced factor-1α in endometrial carcinoma: a mini-review of current evidence.

Despite the well-established role of hypoxia in cancer biology, the literature on its effects on endometrial cancer is scarce; it mainly refers to experimental settings rather than patient-derived results. Herein, an overview of the hypoxia inducible factor 1α (HIF-1α) biology, focusing on endometrial cancer, is presented. The molecular mechanisms possibly involved in endometrial cancer progression are presented, followed by a systematic approach to the current literature on immunohistochemistry evaluation of HIF-1α expression in endometrial carcinoma.

Sentinel lymph node detection by intranipple injection of patent blue dye in breast cancer: a preliminary report of a feasibility study.

Sentinel lymph node (SLN) biopsy is a well established option for assessing axillary lymph node status in breast cancer. Several techniques have been applied so far (superficial or deeper ones). Based on anatomical features of the lymphatic drainage in the breast, we assessed the feasibility of an intranipple approach for SLN mapping.

Immunohistochemical study of the angiogenetic network of VEGF, HIF1α, VEGFR-2 and endothelial nitric oxide synthase (eNOS) in human breast cancer.

Background: The role of Nitric Oxide (NO) in angiogenesis has not been fully clarified yet. A dual role for NO, either inductive or inhibitory, has been proposed on the basis of different effects that high or low concentrations of NO may exert on the angiogenic process. Additionally, it has been referred that NO may induce VEGF production, while VEGF may induce NO production via up-regulation of the endothelial nitric oxide synthase (eNOS), the two pathways being reverse.

Primary atypical carcinoid of the breast: a case report and brief overview of evidence.

Primary atypical carcinoid of the breast is rare. Herein we present a case of atypical carcinoid of the breast treated with surgery. The management plan is commented.
