Conventional molecular assessment of tissue through histology, if adapted to fresh thicker samples, has the potential to enhance cancer detection in surgical margins and monitoring of 3D cell culture molecular environments. However, in thicker samples, substantial background staining is common despite repeated rinsing, which can significantly reduce image contrast. Recently, 'paired-agent' methods-which employ co-administration of a control (untargeted) imaging agent-have been applied to thick-sample staining applications to account for background staining...

Harmful mutations of the BRCA tumor suppressor genes result in a greater lifetime risk for malignancy-breast and ovarian cancers in particular. An increased risk for male breast, fallopian tube, primary peritoneal, pancreatic, prostate, and colon cancers also has been reported. The BRCA gene is inherited in an autosomal dominant pattern and tends to be highly penetrant; thus, there is an increased incidence of these cancers in affected families. Compared with sporadic tumors, BRCA-associated malignancies have unique manifestations, clinical features, and pathologic profiles...

Public health messages can be used to increase awareness about colorectal cancer screenings. Free or inexpensive images for creating health messages are readily available, yet little is known about how a pictured individual's engagement in the behavior of interest affects message outcomes. Participants ( N = 360), aged 50 to 75 years, completed an online survey in which they viewed a colorectal cancer screening message and were then randomly assigned to view one of four different messages about the pictured individual's screening status...

A hybrid vector of adeno-associated virus and phage (termed AAVP) has been introduced as a platform for systemic ligand-directed delivery of transgenes to tumors over the past decade. A series of studies have evaluated the AAVP platform for potential theranostic or purely therapeutic applications in several tumor models. Sufficient ligand-directed tumor targeting consistently resulted in specific molecular-genetic imaging and/or anti-tumor responses to 'suicide' transgene delivery. However, efforts to optimize transduction efficiency are still ongoing...

Hepatitis B virus capsid (HBVC), a self-assembled protein nanoparticle comprised of 180 or 240 subunit proteins, is used as a cage for genetic encapsulation of fluorescent proteins (FPs). The self-quenching of FPs is controlled by varying the spacing between FPs within the capsid structure. Double-layered FP nanoparticle possessing cancer cell-targeting capabilities is also produced by additionally attaching FPs and cancer cell receptor-binding peptides (affibodies) to the outer surface of the capsid. The generically modified HBVC with double layers of mCardinal FPs and affibodies (mC-DL-HBVC) exhibit a high fluorescence intensity and a strong photostability, and is efficiently internalized by cancer cells and significantly stable against intracellular degradation...

Twenty-five to thirty percent of patients with prostate cancer present with locally advanced disease. While risk stratification remains the same with high incidence of upstaging of disease on imaging and histopathological evaluation; there have been progressive refinements in surgical therapy. With availability of reasonably robust data, radical prostatectomy in men with locally advanced prostate cancers seems to effect improvement in both cancer specific and overall survival rates in comparison to the current standard of care of radiation with androgen deprivation therapy...

Screening of prostatic cancer is a matter of debate among uro-oncologist. With many new screening modalities like prostatic health index (PHI), 4K testing the role of screening has increased as one is able to stratify patients with serum prostate specific antigen level in a grey zone of 4-10 ng/ml and normal digital rectal examination into various risk groups, thus avoiding unnecessary biopsy which was the pitfalls of routine screening practice. PHI is better at predicting malignancy while 4K is better at predicting high-grade disease...

The erythropoietin producing hepatoma A2 receptor (EphA2) is a tyrosine kinase overexpressed by tumor stroma and cancer cells. High expression level of EphA2 predicts poor prognosis, correlating with disease progression and metastasis. Therefore, EphA2 is a relevant therapeutic target for human cancer. Antibodies, selectively bound to EphA2 receptor, can induce rapid receptor phosphorylation that results in antibody internalization and degradation. This internalization mechanism has been exploited with the development of antibody-drug conjugates (ADC) for cancer chemotherapy...

Positron-emission-tomography (PET) combined with computed-tomography (CT) and prostate-specific-membrane-antigen (PSMA) ligands has gained significant interest for staging prostate cancer (PC). In this study, we propose two multimodal quantitative indices as imaging biomarker for the assessment of osseous tumour burden using (68)Ga-PSMA-PET/CT and present preliminary clinical data. We define two Bone-PET-Indices (BPI) that incorporate anatomical information from CT and functional information from (68)Ga-PSMA-PET: BPIVOL is the percental bone volume affected by tumour...
