Approximately 35% of breast cancers exhibit PIK3CA activating mutation. Since PIK3CA hotspot mutation is the most frequently mutated gene in human breast cancers and primarily overlaps in HER2+ as well as ER+ breast cancers, the subset of patients bearing PIK3CA activating mutation does not get fullest benefit from either anti-HER2 or anti-hormonal agents. Literature also suggests that these pa...
How useful are hereditary cancer susceptibility syndromes for modeling sporadic cancers? If the biology of cancers developing within hereditary syndromes follows the same pathways to malignancy as does a substantial proportion of sporadic cancers, then prevention trials focused on hereditary high-risk individuals can lead to important gains in the sporadic setting. McKusick struggled with this ...
BACKGROUND The aim of this study was to investigate whether the anisotropy parameters are helpful in the detection and discrimination of breast cancers, and to determine its value in predicting the risk of cancers. MATERIAL AND METHODS There were 56 patients with 56 lesions (34 malignant, 22 benign) included in the study. DTI was performed in every patient and apparent diffusion coefficient (AD...
The pathogenesis of breast cancers that do not express estrogen receptors or Her-2/neu receptors (ER-/HER2- phenotype) is incompletely understood. We had observed markedly elevated gene expression of gamma-aminobutyric acid type A (GABA(A)) receptor subunit pi (GABApi, GABRP) in some breast cancers with ER-/HER2- phenotype. In this study, transcriptional profiles (TxPs) were obtained from 82 pr...
BACKGROUND Prognosis of breast cancer and success of therapeutic interventions largely rely on the clinico-pathologic and biological characteristics of the tumor and vary due to the heterogeneous nature of breast cancers. The aim of this study was to determine the frequency and prognostic parameters of luminal breast cancers in our population to devise targeted and personalized therapeutic regi...
PURPOSE BRCA1-related breast cancers are more frequently estrogen receptor (ER) negative than are either BRCA2-related or nonhereditary breast cancers. The relationship between ER status and other clinical features of hereditary breast cancers has not been well studied. EXPERIMENTAL DESIGN ER status, grade, and histological tumor type were evaluated in 1131 women with invasive breast cancer, ...
The average hospital bill for gynecologic cancers overall was almost $24,700—25 percent higher than the average U.S. hospital bill of $19,700. For ovarian cancer, the average bill was $35,200—nearly 80 percent higher than the average U.S. hospital bill (Figure 2). More than 1 in 3 American women develop cancer at some point in their lives. Over 40 percent1 of their diagnoses are associated with...
The aim of this study was to investigate succinate dehydrogenase (SDH) expression in breast cancer according to breast cancer molecular subtype using immunohistochemistry and to assess the clinical implications of SDH expression. Immunohistochemical staining for ER, PR, HER-2, Ki-67, HIF-1α, SDHA, and SDHB was performed on tissue microarrays of 721 breast cancers. According to the immunohistoch...
Introduction: Among women’s cancers, breast and cervical cancers are most common with high mortality rate, but they can be rectified in the initial stages with cost-effective, easy and readily available screening programs. The task of informing the community and directing them towards the screening programs is one of the major responsibilities of the health team. Objective: Determining the scr...
PURPOSE The transforming growth factor-beta (TGF-beta) signaling pathway has been frequently implicated in breast cancer. An intronic variant (Int7G24A) of TGF-beta receptor type I (TGFBR1) is associated with kidney and bladder cancers in our recent study. We hypothesize that this germline variant may be involved in development and progression of breast cancer. EXPERIMENTAL DESIGN Case-contro...
