Clinicopathological significance of insulin-like growth factor-1 receptor expression in breast cancer.

Objective: Insulin-like growth factor 1 receptor (IGF1R) is a receptor protein tyrosine kinase that is claimed to be related with tumor development and progression of breast cancer with some conflicting results in the literature. The aims of the study are to investigate expression of IGF1R, and correlate with clinicopathological parameters to clarify the significance of IGF1R on breast cancer.

Material And Methods: IGF1R and Ki67 were applied immunohistochemically to the tissue microarray sections of 370 female breast cancer patients.

GATA3 expression and its relationship with clinicopathological parameters in invasive breast carcinomas.

GATA3, as a transcription factor, is associated with estrogen receptor (ER) expression and necessary for luminal cell differentiation in mammary glands. Association of GATA3 expression with clinicopathological parameters, molecular subtypes of tumors, disease free survival (DFS) and overall survival (OS) for breast carcinoma patients were evaluated in this study. We immunohistochemically stained GATA3, CK5/6, EGFR, CK14 and vimentin on tissue microarray blocks of 457 invasive breast carcinomas.

Clinicopathological Significance of the Proliferation Markers Ki67, RacGAP1, and Topoisomerase 2 Alpha in Breast Cancer.

Objectives The aims of this study are to evaluate expressions of Ki67, RacGAP1 (MgcRacGAP) and topoisomerase 2 alpha (TOP2a), the markers related with cell proliferation that have been proposed to affect the prognosis in the literature and correlate the results with clinicopathological parameters of breast cancer patients. Methods Ki67, RacGAP1, and TOP2a antibodies were applied immunohistochemically to the tissue micrarray blocks of 457 female breast cancer patients. The results were correlated with clinical, prognostic, histopathological features, and other immunohistochemical findings (estrogen receptor [ER], progesterone receptor [PR], HER2, cytokeratin [CK]5/6, CK14, epidermal growth factor receptor [EGFR] and vimentin), statistically.

A rare case of primary inoculation tuberculosis seen after varicella.

Primary inoculation tuberculosis (TB) is a rare form of cutaneous TB resulting from direct introduction of Mycobacterium tuberculosis into the skin or mucosa of a previously uninfected, nonimmune person. We herein report the first case, to our knowledge, of primary inoculation TB to be seen after varicella; this case explains the possible mechanism of varicella-zoster virus-mediated transient cellular immune suppression that predisposed the patient to cutaneous TB. In this case, we believe that varicella-zoster virus (VZV) infection predisposed the patient to primary inoculation TB by leading to direct inoculation of tuberculosis bacilli through vesicles or by suppressing cellular immunity.

Secondary Neoplasms in Children with Hodgkin's Lymphoma Receiving C-MOPP and Radiotherapy: Presentation of Four Cases.

Patients who survive Hodgkin lymphoma (HL) are at increased risk of secondary neoplasms (SNs). A wide variety of SNs have been reported, including leukemias, non-Hodgkin's lymphomas, and solid tumors, specifically breast and thyroid cancers. Herein we report subsequent neoplasms in four patients with HL receiving chemoradiotherapy.
