PURPOSE: Hormone receptor-positive (HR+) tumors have heterogeneous biology and present a challenge for determining optimal treatment. In the Neoadjuvant Breast Registry Symphony Trial (NBRST) patients were classified according to MammaPrint/BluePrint subtyping to provide insight into the response to neoadjuvant endocrine therapy (NET) or neoadjuvant chemotherapy (NCT). OBJECTIVE: The purpose of this predefined substudy was to compare MammaPrint/BluePrint with conventional 'clinical' immunohistochemistry/fluorescence in situ hybridization (IHC/FISH) subtyping in 'clinical luminal' [HR+/human epidermal growth factor receptor 2-negative (HER2-)] breast cancer patients to predict treatment sensitivity...

BACKGROUND: Mucinous appendiceal neoplasms (MAN) with peritoneal dissemination is treated as a standard of care using cytoreductive surgery and hyperthermic perioperative chemotherapy. The extent of the resection of peritoneal surfaces and visceral structures is generally well defined. Exception to this consensus regarding structures to be removed are the right colon and adjacent ileocolic lymph nodes. METHODS: From a prospectively maintained database, all patients with a histologic diagnosis of peritoneal mucinous carcinoma (PMCA) who underwent complete cytoreductive surgery were assessed for the presence versus absence of adenocarcinoma in lymph nodes within the appendiceal mesentery and/or in the lymph nodes of the ileocolic group...

BACKGROUND: Gastric cancer (GC) relapse can occur even if curative resection is achieved. Biomarkers predicting recurrence are needed to provide appropriate postoperative surveillance and perioperative therapeutic strategy. METHODS: A global expression profiling was performed using tissues from GC patients with synchronous liver-confined metastasis. Family with sequence similarity 46, member C (FAM46C), was identified as a candidate biomarker. mRNA expression analysis, direct nucleotide sequencing, bisulfite sequencing and copy number assays for FAM46C were performed with eleven GC cell lines...

BACKGROUND: The RND1 gene encodes a protein that belongs to the Rho GTPase family, which regulates various cellular functions. Depletion of RND1 expression activates the oncogenic Ras signaling pathway. In this study, we aimed to clarify the clinical significance of RND1 expression in predicting prognosis and to investigate its biological role in human hepatocellular carcinoma (HCC). METHODS: The association between RND1 expression and clinical outcomes in patients with HCC was analyzed in three independent cohorts: 120 cases resected in our hospital; 370 cases in The Cancer Genome Atlas (TCGA); and 242 cases in GSE14520...

BACKGROUND: Neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and lymphocyte-monocyte ratio (LMR) may serve as a simple index of the immune function. The aim of this study was to investigate the prognostic significance of NLR, PLR, and LMR in patients with resectable pancreatic ductal adenocarcinoma (PDAC) and to verify whether such biomarkers are associated with changes in populations of lymphoid cells. METHODS: The prognostic implications of blood count parameters were evaluated in a retrospective cohort of 442 subjects undergoing pancreatic resections for PDAC...

BACKGROUND: Older patients with localized gastric adenocarcinoma (LGAC) have substantial postoperative morbidity and mortality; however, postoperative outcomes of the patients who receive preoperative chemotherapy and/or chemoradiation have not been reported. We examined the impact of age at baseline on potential predictors of postoperative outcomes. METHODS: Patients with LGAC who were treated with chemotherapy and/or chemoradiation followed by surgery (n = 203) formed two groups: (1) ≥65 years old (n = 70) and (2) <65 years old (n = 133)...

BACKGROUND: The extent of tumor resection (EOTR) calculated by enhanced T1 changes in glioblastomas has been previously reported to predict survival. However, fluid-attenuated inversion recovery (FLAIR) volume may better represent tumor burden. In this study, we report the first assessment of the dynamics of FLAIR volume changes over time as a predictive variable for post-resection overall survival (OS). METHODS: Contemporary data from 103 consecutive patients with complete imaging and clinical data who underwent resection of newly diagnosed glioblastoma followed by the Stupp protocol between 2010 and 2013 were analyzed...

INTRODUCTION: Cancer screening is a key component of primary care, and access to regular screening mammography (SMG) is highly dependent on recommendation and referral by a primary care provider (PCP). Women with no health insurance or who are underinsured often lack access to a regular PCP and thus access to routine screening. METHODS: We retrospectively reviewed the charts of 173 surgical patients diagnosed between January 2012 and December 2013. The main outcome variables were PCP status, method of cancer detection, and breast cancer stage at diagnosis...

BACKGROUND: Identifying DCIS patients at low risk for disease progression could obviate need for standard therapy. The LORIS (surgery versus active monitoring for low-risk DCIS) trial is studying the safety of monitoring low-risk DCIS, although ipsilateral breast tumor recurrence (IBTR) rates in patients meeting enrollment criteria after complete surgical excision are unknown. METHODS: Women with pure DCIS treated with breast-conserving surgery (BCS) with/without radiation therapy (RT) from 1/1996-1/2011 were included from a prospectively maintained database...

BACKGROUND: Intraoperative parathyroid hormone (IOPTH) monitoring is crucial in the treatment of primary hyperparathyroidism (PHPT). Often, the 5 min IOPTH levels fall, but not by the requisite 50 %. In such cases, the surgeon must decide whether to wait for additional levels or to continue exploration. This study aimed to evaluate the 5 min drop in IOPTH for distinguishing single adenomas (SA) from multigland disease. METHODS: A retrospective analysis of a prospectively collected database was performed on PHPT patients who underwent initial curative parathyroidectomy between 2001 and 2013...

BACKGROUND: Cancer survivorship focuses largely on improving quality of life. We aimed to determine the rate of ventral incisional hernia (VIH) formation after cancer resection, with implications for survivorship. METHODS: Patients without prior VIH who underwent abdominal malignancy resections at a tertiary center were followed up to 2 years. Patients with a viewable preoperative computed tomography (CT) scan and CT within 2 years postoperatively were included...
