Stroma tissue surrounding cancer cells plays an important role in tumor development and behavior. In colorectal cancer, it has been found that the amount of stroma within the primary tumor is of prognostic value. We therefore have evaluated the prognostic value of this tumor–stroma ratio for breast cancer. A cohort of 574 early breast cancer patients,(More)
PURPOSE Studies on quality of life (QOL) among women with endometrial cancer have shown that patients who undergo pelvic radiotherapy report lower role functioning and more diarrhea and fatigue. In the Post Operative Radiation Therapy in Endometrial Cancer (PORTEC) trial, patients with endometrial carcinoma were randomly assigned to receive external-beam(More)
PURPOSE In 2000, the results of the multicenter Post Operative Radiation Therapy in Endometrial Carcinoma (PORTEC) trial were published. This trial included 714 Stage I endometrial carcinoma patients randomly assigned to postoperative pelvic radiotherapy (RT) or no further treatment, excluding those with Stage IC, Grade 3, or Stage IB, Grade 1 lesions.(More)
Epithelial mesenchymal transition (EMT) plays an important role in the development of metastases. One of the hallmarks of EMT is loss of E-cadherin and gain of N-cadherin expression, which are regulated by transcription factors, such as SNAIL, SLUG, and TWIST. We examined the prognostic value of these factors as well as E-cadherin and N-cadherin, in a(More)
Breast cancers demonstrate substantial biological, clinical and etiological heterogeneity. We investigated breast cancer risk associations of eight susceptibility loci identified in GWAS and two putative susceptibility loci in candidate genes in relation to specific breast tumor subtypes. Subtypes were defined by five markers (ER, PR, HER2, CK5/6, EGFR) and(More)
PURPOSE Women carrying a CHEK2*1100delC germline mutation have an increased risk of developing breast cancer. This study aims to determine the proportion of CHEK2*1100delC carriers in a premenopausal breast cancer population, unselected for family history of breast cancer, and to investigate tumor characteristics and disease outcome with sufficient(More)
The switch/sucrose non-fermentable (SWI/SNF) subunit ARID1A (AT-rich interactive domain 1A gene) has been recently postulated as a novel tumor suppressor of gynecologic cancer and one of the driver genes in endometrial carcinogenesis. However, specific relationships with established molecular alterations in endometrioid endometrial cancer (EEC) are(More)
PURPOSE We hypothesized that T-cell immune interaction affects tumor development and thus clinical outcome. Therefore, we examined the clinical impact of human leukocyte antigen (HLA) class I tumor cell expression and regulatory T-cell (Treg) infiltration in breast cancer. EXPERIMENTAL DESIGN Our study population (N = 677) is consisted of all early breast(More)
BACKGROUND The fundamental principle of oncologic surgery is the complete resection of malignant cells. However, small tumors are often difficult to find during surgery using conventional techniques. The objectives of this study were to determine if optical imaging, using a contrast agent already approved for other indications, could improve hepatic(More)
Nonclassical HLAs, HLA-E and HLA-G, are known to affect clinical outcome in various tumor types. We examined the clinical impact of HLA-E and HLA-G expression in early breast cancer patients, and related the results to tumor expression of classical HLA class I. Our study population (n = 677) consisted of all early breast cancer patients primarily treated(More)
