Quantification of collagen content and stromal cellularity within reactive stroma is predictive of prostate cancer biochemical recurrence and specific death.

Semiquantitative reactive stromal grading has been shown to be a predictor of biochemical recurrence and prostate cancer (PCa) specific death. It has been extensively validated. In this study we tested novel technologies to introduce quantitative measures of host response, in particular collagen content and stromal cellularity.

Breast cancer global tumor biomarkers: a quality assurance study of intratumoral heterogeneity.

Biomarker analysis of invasive breast carcinoma is useful for prognosis, as surrogate for molecular subtypes of breast cancer, and prediction of response to adjuvant and neoadjuvant systemic therapies. Breast cancer intratumoral heterogeneity is incompletely studied. Comprehensive biomarker analysis of estrogen receptor (ER), progesterone receptor (PR), HER2, and Ki67 labeling index was performed on each tissue block of 100 entirely submitted breast tumors in 99 patients.

Well Differentiated Endometrioid Adenocarcinoma of the Endometrium with "Adenoma Malignum-Like" Pattern of Invasion: Report of Two Cases and Review of Literature.

Unusual variants of endometrial endometrioid adenocarcinoma can be diagnostically challenging and pose difficulties to differentiate from their benign and malignant mimickers. Here we describe an entity that has been well documented in the literature, yet little is known about true outcome due to lack of studies with a large number of cases. Diffusely infiltrative or "adenoma-malignum-like" is an uncommon pattern of invasion in endometrioid endometrial adenocarcinoma which could be confused with adenomyosis.

Primary Pure Endometrial Primitive Neuroectodermal Tumors with Gene Rearrangement: Report of 2 Cases.

Primary Primitive Neuroectodermal Tumor (PNET) of the female genital tract is very rare. The majority has been described in ovaries, and the endometrium is an even rarer site. Herein we describe 2 cases of primary uterine corpus PNET cases with FISH confirmation.

Morphoproteomics Identifies the EZH2 and SIRT1 Pathways as Potential Blocks to Differentiation in Yolk Sac Tumor of the Ovary and Provides Therapeutic Options: a Case Study.

Yolk sac tumor of the ovary is a rare but highly malignant and aggressive germ cell tumor. The objective of this case study of an ovarian yolk sac tumor was to identify putative pathways that are known to pose a block in differentiation, both in early embryogenesis and in tumorigenesis, that might be amenable to low toxicity therapies designed to promote differentiation to a more benign state and prevent recurrent disease in such tumors. The enhancer of Zeste homolog 2 (EZH2), a histone methyl transferase, and silent mating type information regulation 2 homolog 1 (SIRT1), a NAD+ histone deacetylase, are two such pathways.

Prospective cohort study of cancer patients diagnosed with incidental venous thromboembolism on routine computed tomography scans.

Purpose: Venous thromboembolism (VTE) is a major complication of cancer with recent increasing reports of incidental VTE. The objectives are to estimate the prevalence of incidental VTE in cancer patients on staging CT scans, identify common symptoms, and determine VTE recurrence in a prospective study.

Patients And Methods: One thousand ninety patients were studied.

Expression of Sirt1 and FoxP3 in classical Hodgkin lymphoma and tumor infiltrating lymphocytes: Implications for immune dysregulation, prognosis and potential therapeutic targeting.

Background: Hodgkin Reed-Sternberg (HRS) cells may promote differentiation of CD4+ naïve T cells toward both FoxP3+ T regulatory (Treg) cells and TIA-1+ cytotoxic T lymphocytes (CTL). Previous studies suggest that an overabundance of cytotoxic TIA-1+ cells in relation to FoxP3+ T reg cells portends unfavorable outcomes in classical Hodgkin lymphoma (cHL), raising the possibility that its pathogenesis may be related to immune dysregulation. Sirt1 deacetylates FoxP3 and leads to decreased Treg functionality.
