PURPOSE This study was designed to evaluate the associations between angiogenesis gene polymorphisms and clinical outcome in ovarian cancer patients treated with low-dose cyclophosphamide and bevacizumab. EXPERIMENTAL DESIGN Seventy recurrent/metastatic epithelial ovarian cancer patients were enrolled in a phase II clinical trial. Genomic DNA was available from 53 blood samples. Polymorphisms...
We evaluated the survival effect of adjuvant concurrent chemoradiotherapy after radical hysterectomy in patients with clinical pelvic node-positive cervical adenocarcinoma. Patients adenocarcinoma diagnosed between 2000 and 2016 at our institution were identified. Survival was compared who underwent alone those received as an treatment. analysis using log-rank test Cox proportional hazards mode...
OBJECTIVE The purpose of this study was to identify the clinicopathological characteristics and prognostic value of p53 overexpression in breast cancer patients treated with a modified radical mastectomy. METHODS The medical records of 197 patients who had undergone modified radical mastectomy between January 1991 and December 2008 were reviewed retrospectively. Breast cancer subtype and p53 ...
Only recently progress has been made in obtaining o(log(rank))-competitive algorithms for the matroid secretary problem. More precisely, Chakraborty and Lachish (2012) presented a O( √ log(rank))-competitive procedure, and Lachish (2014) later presented a O(log log(rank))competitive algorithm. Both these algorithms and their analyses are very involved, which is also reflected in the extremely h...
OBJECTIVES To investigate the characteristics associated with survival in esthesioneuroblastoma and to determine whether the modified Kadish staging system can predict outcome. DESIGN Retrospective population-based cohort study. SUBJECTS All patients in the Surveillance, Epidemiology, and End Results tumor registry diagnosed as having esthesioneuroblastoma (1973-2002). MAIN OUTCOME MEASUR...
Only a minority of patients find a fully compatible donor for hematopoietic stem cell transplantation (HSCT). In the absence of human leukocyte antigen-matched related or unrelated donors, haploidentical donors (HAPLO) and umbilical cord blood and placental (UCB) cells are alternatives for patients with malignant and non-malignant hematological diseases. However, the risk of graft-versus-host d...
BACKGROUND By using web-based tools in medical education, there are opportunities to innovatively teach important principles from the general competencies of graduate medical education. OBJECTIVES Postulating that faculty transparency in learning from uncertainties in clinical work could help residents to incorporate the principles of practice-based learning and improvement (PBLI) in their pr...
Receptor activator of NF-kB (RANK) pathway regulates bone remodeling and is involved in breast cancer (BC) progression. Genetic polymorphisms affecting RANK-ligand (RANKL) and osteoprotegerin (OPG) have been previously associated with BC risk and bone metastasis (BM)-free survival, respectively. In this study we conducted a retrospective analysis of the association of five missense RANK SNPs wi...
