Abstract The worldwide mortality rate due to cancer is second only to cardiovascular diseases. The discovery of image processing, latest artificial intelligence techniques, and upcoming algorithms can be used to effectively diagnose and prognose cancer faster and reduce the mortality rate. Efficiently applying these latest techniques has increased the survival chances during recent years. The research community is making significant continuous progress in developing automated tools to assist dermatologists in decision making. The datasets used for the experimentation and analysis are ISBI 2016, ISBI 2017, and HAM 10000. In this work pertained models are used to… More >

Abstract Collective improvement in the acceptable or desirable accuracy level of breast cancer image-related pattern recognition using various schemes remains challenging. Despite the combination of multiple schemes to achieve superior ultrasound image pattern recognition by reducing the speckle noise, an enhanced technique is not achieved. The purpose of this study is to introduce a features-based fusion scheme based on enhancement uniform-Local Binary Pattern (LBP) and filtered noise reduction. To surmount the above limitations and achieve the aim of the study, a new descriptor that enhances the LBP features based on the new threshold has been proposed.… More >

Abstract Introduction: The aim of this study was to evaluate the value of dynamic contrast enhanced (DCE) imaging in multi-parametric prostate MRI (mpMRI) for the detection and staging of prostate cancer in comparison with T2W and DWI images alone in biparametric MRI (bpMRI) in treatment-naïve patients.
Materials and methods: One hundred consecutive patients who underwent a prostate MRI at our institution from June-August 2017, as well as a systematic ultrasound-guided prostate biopsy or prostatectomy, were included. Strictly following PI-RADS v2, the MRI studies were independently interpreted by a body radiologist and a body-imaging fellow on two different occasions… More >

Abstract In this paper, we address a current problem in medical image processing, the detection of colorectal cancer from colonoscopy videos. According to worldwide cancer statistics, colorectal cancer is one of the most common cancers. The process of screening and the removal of pre-cancerous cells from the large intestine is a crucial task to date. The traditional manual process is dependent on the expertise of the medical practitioner. In this paper, a two-stage classification is proposed to detect colorectal cancer. In the first stage, frames of colonoscopy video are extracted and are rated as significant if More >

Abstract Introduction: To report the incidence and characteristics of cancer following a diagnosis of atypical small acinar proliferation (ASAP) and comment on current clinical practice recommendations.
Materials and methods: We reviewed patients that underwent prostate biopsy between 2008 and 2013 at a single institution. Men with ASAP without previous cancer were included. Clinicopathologic features including prostate-specific antigen (PSA), presence of ASAP or cancer, tumor volume, number of involved cores, and Gleason score were analyzed in men that received a repeat prostate biopsy.
Results: Of 1450 men, ASAP was found in 75 (5%) patients. Repeat biopsy was performed in 49… More >

Abstract Introduction: To evaluate Prostate Cancer Prevention Trial (PCPT) risk calculator versus prostate cancer gene 3 (PCA3) score versus case-finding protocol accuracy in prostate cancer diagnosis in patients with prostate-specific antigen (PSA) below 10 ng/mL submitted to repeat saturation biopsy (SPBx).
Materials and methods: From December 2010 to December 2011, 100 patients (median 66 years) underwent a SPBx (median 30 cores); the indications for repeat biopsy were those of a case-finding protocol: PSA values between 4.1 ng/mL-10 ng/mL or 2.6 ng/mL-4 ng/mL with F/T PSA ≤ 25% and ≤ 20%, respectively. All patients had negative digital rectal examination… More >

Abstract Introduction: Several studies, including the recently published phase III study by Stenzl and colleagues, have demonstrated that hexaminolevulinate hydrochloride, when used with blue light fluorescence cystoscopy, improves detection of non-muscle invasive bladder tumors compared to white light cystoscopy and transurethral resection of bladder tumors (TURB) alone.
Materials and methods: The objective of this study was to conduct a detailed assessment of the cost-effectiveness of using hexaminolevulinate hydrochloride with blue light cystoscopy as an adjunct to white light versus white light cystoscopy alone at the time of initial TURB in the United States. A probabilistic decision tree model, More >

Abstract Introduction: The detection of prostate carcinoma relies on adequate sampling. We aimed to evaluate whether core length is a significant biopsy parameter in the detection of cancer, especially in the low risk cancer category group.
Materials and methods: We retrospectively analyzed pathology reports of 197 patients (2196 biopsy cores) undergoing initial transrectal ultrasound-guided biopsy. A multivariate analysis of age, total prostate-specific antigen (PSA) concentration, prostate gland volume, total number of cores, and length of biopsy cores was performed. Secondary analyses included stratification by Gleason score. Single core analysis was done to calculate a workable cut-off value for… More >

Abstract Prostate cancer is a highly prevalent malignancy. Using serum prostatic-specifi c antigen (PSA) levels to screen for prostate cancer has led to a greater detection of this cancer, at earlier stages. However, screening for prostate cancer by determining PSA levels remains controversial. Concerns include the risk of overdiagnosis and conversely, the failure to detect all prostate cancers. This article, aimed at primary care practitioners, reviews the characteristics of an ideal screening test, in relation to the characteristics of the PSA test. It then discusses the implications of recent fi ndings from two large, randomized, prospective More >

Abstract Objective: To compare the detection and management of prostate cancer in one French and six Chinese urological institutions.
Patients and methods: All the patients subjected to prostate biopsy for suspected prostate cancer in six Chinese urological institutions and in the department of urology of the Cochin hospital, France, between January 2003 and December 2005 were included. The characteristics of patients and tumors, and the management of prostate cancer were then analyzed.
Results: In the Chinese institutions, 95.8% of patients undergoing prostate biopsy presented with urinary disorders. The rate of abnormal digital rectal examination (DRE) ranged from 29.2% to… More >
