OBJECTIVE: Sentinel lymph node (SLN) mapping for endometrial (EC) and cervical cancers (CC) is a current technique that could provide benefits over traditional lymphadenectomy. Near-infrared (NIR) fluorescence imaging is a promising technique to perform this procedure. We conducted a systematic review of the evidence regarding the technique and the effectiveness of indocyanine green (ICG) during SLN biopsy, using robotic and laparoscopic assisted surgery and laparotomy. MATERIALS AND METHODS: We conducted a computer literature search for published English language studies in humans using PubMed since January 2010 up to May 2015...

INTRODUCTION: In the U.S., people of different races/ethnicities have differences in cancer incidence, mortality, survival, stage at diagnosis, and receipt of treatment, resulting in variances in cancer burden. The burden of cancer in 2011 was assessed by race/ethnicity for 24 cancers using disability-adjusted life years (DALYs). METHODS: In 2014-2015, DALYs and their two components were estimated (years of life lost [YLLs] and years lived with disability) by race/ethnicity using population-based cancer registry data collected in 2013, vital statistics, and literature reviews...

Pap test involves searching of morphological changes in cervical squamous epithelial cells by pathologists or cytotechnologists to identify potential cancerous cells in the cervix. Nuclear membrane irregularity is one of the morphological changes of malignancy. This paper proposes two novel techniques for the evaluation of nuclear membrane irregularity. The first technique, namely, penalty-driven smoothing analysis, introduces different penalty values for nuclear membrane contour with different degrees of irregularity...

Glycolysis provides precursors for the synthesis of macromolecules and may contribute to the ATP supply required for the constant and accelerated cellular duplication in cancer cells. In consequence, inhibition of glycolysis has been reiteratively considered as an anti-cancer therapeutic option. In previous studies, kinetic modeling of glycolysis in cancer cells allowed the identification of the main steps that control the glycolytic flux: glucose transporter, hexokinase (HK), hexose phosphate isomerase (HPI), and glycogen degradation in human cervix HeLa cancer cells and rat AS-30D ascites hepatocarcinoma...

Invasive squamous cell carcinoma (SCC) of the cervix involves the progression of premalignant cervical intraepithelial neoplasia (CIN) and is associated with persistent human papilloma virus (HPV) infection. Most CINs will regress, and the challenge is to identify the lesions likely to progress to invasive cancer. We evaluated Sirtuin1 (SIRT1) expression in non-neoplastic cervix, CINs and SCC as a potential biomarker to predict disease progression. A total of 101 cases were selected including 29 CIN 1, 32 CIN 2, 16 CIN 3, 2 microinvasive SCC and 22 invasive SCC...

Current ASCCP guidelines recommend repeat cytology 12 months after HPV-positive results in women aged 21-24 years with either atypical squamous cells of undetermined significance (ASCUS) or a low-grade squamous intraepithelial lesion (LSIL). The purpose of this study was to validate an algorithm in such women with ASCUS or LSIL. A multicenter cross-sectional study was carried out at three academic hospitals involving 40,847 Korean women who underwent cervical cancer screening with cytology and HPV testing with or without subsequent colposcopic biopsies between January 2007 and December 2013...

INTRODUCTION: Inclusion of multiple independently moving clinical target volumes (CTVs) in the irradiated volume causes an image guidance conundrum. The purpose of this research was to use high risk prostate cancer as a clinical example to evaluate a 'compromise' image alignment strategy. METHODS: The daily pre-treatment orthogonal EPI for 14 consecutive patients were included in this analysis. Image matching was performed by aligning to the prostate only, the bony pelvis only and using the 'compromise' strategy...
