Prostate cancer (PC) is the second most common cause of cancer-related mortality in men in the western world after lung cancer. Many patients are not candidates for resection given the advanced stage of their cancer. The primary treatment for advanced PC is the castration therapy which supresses the production of androgens, hormone that promotes PC growth. Despite the efficiency of the castration therapy, most patients develop castration resistant disease which remains uncurable. Clearly, novel approaches are required to effectively treat castration resistant PC (CRPC)...

PURPOSE: We aim to evaluate prostate-specific antigen (PSA) trends in post-primary focal cryotherapy (PFC) patients. MATERIALS AND METHODS: This was an institutional review board-approved retrospective study of PFC patients from 2010 to 2015. Patients with at least one post-PFC PSA were included in the study. Biochemical recurrence (BCR) was determined using the Phoenix criteria. PSA bounce was also assessed. We analyzed rates of change of PSA over time of post-PFC between BCR and no BCR groups...

BACKGROUND: Studies have shown that exposure to environmental chemicals known as endocrine disruptors can cause permanent changes in genital organs, such as the prostate. Among these environmental chemicals stands out bisphenol A (BPA). Another factor associated with prostate changes is the consumption of a high-fat diet. Although the relationship between the consumption of a high-fat diet and an increased risk of prostate cancer is well established, the mechanisms that lead to the establishment of this disease are not completely understood, nor the simultaneous action of BPA and high-fat diet...

Although prostate cancer responds well to primary endocrine therapies, tumor progression with castration resistant tumor cells almost invariably occurs within a few years. Unfortunately, some CRPC patients do not respond to second-line therapies with abiraterone or enzalutamide. Moreover, patients who initially responded well to second-line hormone therapy develop resistance to abiraterone and/or enzalutamide within a short period of time. Besides an increase of intracellular androgen receptor (AR) levels, the predominant resistance mechanisms include AR aberrations (point mutations, AR splice variants) occurring predominantly at the androgen or ligand binding domain of the AR...

Metastasis is defined as a very inefficient process, since less than 0.01% of cancer cells injected into the circulation will engraft in a distant organ, where they must acquire the ability to survive and proliferate inside a "foreign" environment. In bone metastases, the interaction with the host organ is much more favoured if tumour cells gain "osteomimicry", that is the ability to resemble a resident bone cell (i.e. the osteoblast), thus intruding in the physiology of the bone. This is accomplished by the expression of osteoblast markers (e...

Background: Case-based learning (CBL) is an established pedagogical active learning method used in various disciplines and defined based on the field of study and type of case. The utility of CBL for teaching specific aspects of cancer diagnosis to practising pathologists has not been previously studied in sub-Saharan Africa. Objectives: We aimed to pilot test standardised cancer cases on a group of practising pathologists in sub-Saharan Africa to evaluate case content, clarity of questions and delivery of content...

A systematic review was conducted to categorize the types of cancerous tissues that express orexin receptors and also to examine the effect of in vitro administration of orexin A or B to corresponding cell samples. Comprehensive literature analyses of primary experimental studies were performed. The results of the review included an increased frequency of orexin receptor expression in many colon and prostate cancer tissues and an upward trend of pro-apoptotic activity in these aggressive cell types.

Background: Previous investigations reported inverse relationship between prostate-specific antigen concentration and body mass index (BMI). These results have been explained by a hemodilution effect among obese men. However, the hemodilution of serum carcinoembryonic antigen (CEA) concentration in obese patients with non-small cell lung cancer (NSCLC) has not been ever reported. Methods: Consecutive 381 NSCLC patients were enrolled. A body surface area (BSA)-based and a hematocrit (HCT)-based equations were applied for plasma volume (PV) estimation...

Background: The Gleason score is an essential tool in the decision to treat localized prostate cancer. However, experienced pathologists can classify Gleason score differently than do low-volume pathologists, and this may affect the treatment decision. This study sought to assess the impact of pathology review of external biopsy specimens from 23 men with a recent diagnosis of localized prostate cancer. Methods: All external biopsy specimens were reviewed at our pathology department...

Rationale: Prostate cancer (PCa) is the most common cancer in men worldwide. In general, PCa responds poorly to chemotherapy. Therefore, antibody-drug conjugates (ADCs) have been developed to specifically deliver highly cytotoxic drugs to the tumor. As the prostate-specific membrane antigen (PSMA) is overexpressed in PCa, it represents a promising target for ADC-based therapies. The aim of this study was to evaluate the therapeutic efficacy of site-specifically conjugated duocarmycin- and monomethyl auristatin E (MMAE)-based anti-PSMA ADCs with drug-antibody ratios (DARs) of 2 and 4...

REVIEW

Sipuleucel-T, a therapeutic dendritic-cell vaccine, was Food and Drug Administration-approved for prostate cancer in 2010. No new immunotherapies for prostate cancer have been approved since. However, novel agents and combination approaches offer great promise for improving outcomes for prostate cancer patients. Here we review the latest developments in immunotherapy for prostate cancer. Sipuleucel-T has demonstrated a survival advantage of 4.1 months in metastatic castration-resistant prostate cancer. PSA-TRICOM (PROSTVAC), a prostate-specific antigen-targeted vaccine platform, showed evidence of clinical and immunologic efficacy in early-phase clinical trials, and results from a phase III trial in advanced disease are pending...

BACKGROUND: In Ethiopia, there were greater than 2000 adult and 200 pediatric cancer patients annually in 2010, but the estimated number of cancer patients were increasing. Oncologic rehabilitation treatment may result in improved physical and mental impairment. There is a paucity of information about rehabilitation service utilization among cancer patients in Ethiopia. Hence, the purpose of this study was to assess the rehabilitation service for cancer patient and associated factors at Black Lion hospital, Addis Ababa, Ethiopia...

Prostate cancer research is hampered by the lack of in vivo preclinical models that accurately reflect patient tumour biology and the clinical heterogeneity of human prostate cancer. To overcome these limitations we propagated and characterised a new collection of patient-derived prostate cancer xenografts. Tumour fragments from 147 unsupervised, surgical prostate samples were implanted subcutaneously into immunodeficient Rag2-/-γC-/- mice within 24 hours of surgery. Histologic and molecular characterisation of xenografts was compared with patient characteristics, including androgen-deprivation therapy, and exome sequencing...

Although delayed-time-point imaging is expected to improve the results of [F]-fluorodeoxyglucose (FDG)-positron emission tomography/computed tomography (PET/CT), how examinees will benefit from dual-time-point imaging versus initial-time-point imaging alone, remains unclear. This study investigated the role of delayed-time-point imaging in improving the results of abdominal and pelvic cancer screening using FDG-PET/CT.This retrospective review included 3131 screening results (average subject age: 55.5 years, range: 40-88 years)...

RATIONALE: The image-guided iodine-125 seed implantation has been widely used for a variety of tumors, including prostatic cancer, pulmonary cancer, hepatocellular carcinoma and pancreatic cancer. However, the clinical value of iodine-125 seed implantation for the treatment of pancreatic metastasis from hepatocellular carcinoma has not been reported. We presented the first case with ultrasound-guided iodine-125 seed implantation for this disease. PATIENT CONCERNS: We presented the case of a 48-year-old man patient with primary hepatocellular carcinoma and pancreatic metastasis who was managed with ultrasound-guided iodine-125 seeds implantation...

RATIONALE: Choline (CH) positron emission tomography (PET)/computed tomography (CT) with fluorine 18 (F) CH is increasingly used not only to evaluate patients with biochemically recurrent prostate cancer but also to assess metastatic lesions that are difficult or impossible to identify using more conventional modalities. Our experience with CH PET/CT has shown that it can also be used for many other malignancies. PRESENTING CONCERNS: A 71-year-old male with a neuroendocrine tumor (NET) of unknown origin showed osteoblastic bone metastases positive to F-CH PET...
