PURPOSE OF REVIEW: The purpose is to review recent advances concerning the role of nuclear medicine in endocrine oncology. RECENT FINDINGS: For I therapy of thyroid cancer a thyrotropin (TSH) more than 30 mU/l has for many years been deemed a condition sine qua non. However, new data show that patients with lower TSH levels at the time of ablation have the same rate of successful ablation as those with TSH more than 30 mU/l.I-124 combined integrated positron emission tomography and computed X-ray tomography was shown to be highly accurate in predicting findings on posttherapy radioiodine scanning and was shown to have a high prognostic power...

Colorectal cancer is one of the most frequent neoplasms in western countries; it is the third most common cancer in men after prostate and lung cancer and the second most common in women after breast cancer. Colorectal cancer is usually sporadic but in a small proportion is hereditary. The genetic cause is well established, allowing pre-symptomatic diagnosis in at-risk relatives. The present article reviews the most novel findings presented at the latest meeting of the American Gastroenterological Association on hereditary forms of colorectal cancer, especially Lynch syndrome and MUTYH-associated polyposis, as well as diverse organisational aspects that can favour the correct management of these patients and their relatives...

REVIEW
Roy J Shephard
Prostate cancer affects a major proportion of older men, and effective preventive measures are few. Earlier suggestions of 10-30% risk reduction from vigorous physical activity thus merit further analysis. This narrative review updates information on associations between physical activity and prostate cancer, seeking activity patterns associated with maximal risk reduction. Systematic searches of Ovid/MEDLINE and PubMed databases from 1996 to June 2016 have linked the terms prostate neoplasms/prostate cancer with occupation, occupational title, sedentary job or heavy work, exercise, physical activity, sports, athletes, physical education/training or aerobic fitness...

Radiation therapy represents an alternative treatment to radical prostatectomy in the management of clinically localized prostate cancer. Radiation-induced second neoplasms are defined by a latency period of at least 5 years, location within the field of radiation therapy, and a histology which differs from the primary tumor. Based on the data in the literature, there is a consistently increased risk of bladder cancer (HR: 1.67, 95% CI 1.55-1.80), rectal cancer (HR: 1.79, 95% CI 1.34-2.38), and colorectal cancer (HR: 1...

: Prostate cancer is one of the most frequently detected malignancies in men. The gold standard for its diagnosis is morphological examination; at the same time the differential diagnosis of adenocarcinoma, high-grade prostatic intraepithelial neoplasia (HGPIN), and benign conditions that are able to mimic the malignancies is tremendously difficult in a number of cases, this being so, the hyperdiagnosis rate of HGPIN requiring mandatory repeat biopsy is as high as 24%. The currently available differential diagnostic panel of antibodies is imperfect, which necessitates a search for novel markers...

Non-Hodgkin lymphomas (NHL) are a heterogeneous group of immune cell neoplasms that comprise molecularly distinct lymphoma subtypes. Recent work has identified high frequency promoter point mutations in the telomerase reverse transcriptase (TERT) gene of different cancer types, including melanoma, glioma, liver and bladder cancer. TERT promoter mutations appear to correlate with increased TERT expression and telomerase activity in these cancers. In contrast, breast, pancreatic, and prostate cancer rarely demonstrate mutations in this region of the gene...

BACKGROUND: Diabetes mellitus is a vastly prevalent metabolic disorder with escalating global health concerns. Particularly when mismanaged, chronic micro- and macrovascular complications may highly impair physiological systems while immunodeficiency disposes us to infection. OBJECTIVE: We investigate infections, localized complications, and neoplasms of the genitourinary system secondary to the chronic complications of diabetes mellitus in males and females. METHOD: A comprehensive MEDLINE® search was guided using key words relevant to diabetes mellitus and the genitourinary system...

INTRODUCTION: Autoimmune disorders have been documented in solid tumors and malignant hematological disorders. They are very common and well studied in lymphomas which are associated with immune imbalance. They are less common in solid tumors and are categorized as paraneoplastic syndromes with unclear pathogenesis. AIM: The aim of the present study was to find the frequency of autoimmune phenomena in solid tumors of various origin, location and status of the tumor...

The characteristic immunoprofile for the diagnosis of synovial sarcoma, a neoplasm of unclear tissue origin, is expression of transducer-like enhancer of split 1 (TLE-1), CD99, partial expression of cytokeratin, and epithelial membrane antigen by immunohistochemistry (IHC). Diagnostic dilemma or misdiagnosis can occur due to overlap in IHC and morphology with carcinomas, and particularly poorly differentiated and metastatic tumors. The frequency of TLE-1 and CD99 expression in carcinomas by IHC has not been previously assessed...

Prostate cancer (PCa) is the most common type of neoplasm in European males. Genetic and epigenetic factors contribute to PCa development and progression. In this study, we aimed to assess the relationship between PCa and polymorphisms in the genes encoding endothelial nitric oxide synthase (eNOS), catalase (CAT), and myeloperoxidase (MPO). In total, 193 patients were included in the study. Patients were divided into three groups: PCa (78), benign prostate hyperplasia (40), and control males (75). The parameters assessed included body mass index (BMI), smoking habits, presence of prostatism, prostate-specific antigen (PSA) levels, Gleason scores of prostate specimens, as well as polymorphisms in eNOS-G894T, CAT- 262T, and MPO G-463T genes...

A genome-wide methylation study was conducted among a sample of 114 infants (M age = 13.2 months, SD = 1.08) of low-income urban women with (n = 73) and without (n = 41) major depressive disorder. The Illumina HumanMethylation450 BeadChip array with a GenomeStudio Methylation Module and Illumina Custom model were used to conduct differential methylation analyses. Using the 5.0 × 10-7 p value, 2,119 loci were found to be significantly different between infants of depressed and nondepressed mothers. Infants of depressed mothers had greater methylation at low methylation sites (0%-29%) compared to infants of nondepressed mothers...

PURPOSE: Several studies have suggested that patients with acromegaly have an increased risk of thyroid, colorectal, breast and prostate cancers. In this study we determined the prevalence of malignant neoplasms in patients with acromegaly. METHODS: Cancer risk was evaluated in a cohort of 110 patients (M/F 48/62, age 58.63±13.8 years, range 30-86) with acromegaly. Mean age at diagnosis of acromegaly was 46.37±13.11 years. Mean period of time since diagnosis of acromegaly was 12...

BACKGROUND/AIMS: Patients being treated for prostate cancer (PCa) have an increased risk of developing colorectal cancer. However, whether PCa patients are inherently at a higher risk of colorectal neoplasms (CRNs) is unknown. We aimed to investigate the risk of CRNs in PCa patients. MATERIALS AND METHODS: Patients who had been diagnosed with PCa at a tertiary medical center and had colonoscopy within 1 year of the PCa diagnosis were investigated. Patients were propensity-matched 1:2 by age and body mass index to asymptomatic control subjects who had undergone colonoscopy for routine health screening...

Paget's disease of the bone, historically known as osteitis deformans, is an uncommon disease typically affecting individuals of European descent. Patients with Paget's disease of the bone are at increased risk for primary bone neoplasms, particularly osteosarcoma. Many cases of metastatic disease to pagetic bone have been reported. However, renal cell carcinoma metastasized to pagetic bone is extremely rare. A 94-year-old male presented to the emergency department complaining of abdominal pain. A computed tomography scan of the abdomen demonstrated a large mass in the right kidney compatible with renal cell carcinoma...

Diffuse large B cell lymphoma (DLBCL), currently the most common type of non-Hodgkin lymphoma (NHL), is an aggressive B cell neoplasm that typically presents in older adults as a rapidly enlarging mass. The enlarging mass typically represents a lymph node, although extranodal disease can occur in a significant percentage (40%) of cases. The most common extranodal sites of involvement include the gastrointestinal tract and skin; primary bladder lymphoma represents only 0.2% of extranodal non-Hodgkin lymphomas...

Context .- High-grade neuroendocrine carcinomas and carcinoids can arise in different sites such as lung, gastrointestinal tract, prostate, and skin. Classic neuroendocrine markers such as CD56, synaptophysin, and chromogranin cannot distinguish carcinoids from high-grade neuroendocrine carcinomas. Recently, mouse monoclonal mASH1 has been shown to help discriminate carcinoids from high-grade neuroendocrine carcinomas in various neoplastic sites. To date, there have been no comprehensive immunohistochemistry studies with mASH1 on nonneuroendocrine neoplasms...

Prostatic hyperplasia (PH) is a common urologic disease that affects mostly elderly men. PH can be classified as benign prostatic hyperplasia (BPH), or prostate cancer (PCa) based on its severity. Oxidative stress (OS) is known to influence the activities of inflammatory mediators and other cellular processes involved in the initiation, promotion and progression of human neoplasms including prostate cancer. Scientific evidence also suggests that micronutrient supplementation may restore the antioxidant status and hence improve the clinical outcomes for patients with BPH and PCa...
