: Bladder cancer is one of the most frequent malignancies in the urinary system. Radical cystectomy is inevitable when bladder cancer progresses to a muscle-invasive disease. However, cystectomy still causes a high risk of death and a low quality of life (such as ureter-abdomen ostomy, uroclepsia for ileal-colon neobladder). Therefore, more effective treatments as well as bladder preservation are needed. We developed self-assembled tumor-targeting hyaluronic acid-IR-780 nanoparticles for photothermal ablation in over-expressing CD44 (the receptor for HA) bladder cancer, which show high tumor selectivity, high treatment efficacy, good bioavailability, and excellent biocompatibility...

PURPOSE: Accurate segmentation of organs-at-risks (OARs) is the key step for efficient planning of radiation therapy for head and neck (HaN) cancer treatment. In the work, we proposed the first deep learning-based algorithm, for segmentation of OARs in HaN CT images, and compared its performance against state-of-the-art automated segmentation algorithms, commercial software, and interobserver variability. METHODS: Convolutional neural networks (CNNs)-a concept from the field of deep learning-were used to study consistent intensity patterns of OARs from training CT images and to segment the OAR in a previously unseen test CT image...

Recently, many studies have shown the potential use of circulating exosomes as novel biomarkers for monitoring and predicting a number of complex diseases, including cancer. However, reliable and cost-effective detection of exosomes in routine clinical settings, still remain a difficult task, mainly due to the lack of adequately easy and fast assay platforms. Therefore, we demonstrate here the development of a visible and simple method for the detection of exosomes by integrating single-walled carbon nanotubes that being excellent water solubility (s-SWCNTs) and aptamer...

: 127 Background: Compared with white breast cancer patients, black patients more often report inadequate symptom control and decrements in health-related quality of life (HRQOL). Racial differences in patient-provider communication (PPC) are well-documented and linked to worse health outcomes for minorities; however, less is known about inequities in symptom and HRQOL discussions among cancer patients and providers. As part of an NCI-funded systems change intervention to improve racial equity in treatment completion among Black and White cancer patients, we assessed racial differences in PPC regarding treatment-related symptoms, HRQOL issues (e...

Enzyme-linked immunosorbent assay (ELISA) is a well-known strategy for biomarker detection with a color change, which can be seen by the naked eyes. However, the moderate sensitivity of conventional ELISA limits its applications in many cases where the concentrations of biomarker are very low, such as cancer diagnosis. Here we describe an ultrasensitive colorimetric assay based on acetylcholinesterase (AChE)-catalyzed hydrolysis reaction, whose products trigger the aggregation of gold nanoparticles (AuNPs), causing a distinct color change of the solution from red to purple...

The immune system is a potent inhibitor of tumor growth with curative potential, constituting in many eyes the future of antineoplastic therapy. Adoptive cell therapy (ACT) is a form of immunotherapy in which autologous cancer-cognate lymphocytes are expanded and modified ex vivo and re-infused to combat the tumor. This review follows the evolvement of ACT and treatment protocols, focusing on unresolved dilemmas regarding this treatment while providing evidence for its effectiveness in refractory patients. Future directions of ACT are discussed, in particular with regard to genetic engineering of autologous cells, and the role of ACT in the era of checkpoint inhibitors is addressed...

BACKGROUND: Intraoperative dual-modality imaging can help the surgeon distinguish tumor from normal tissue. This technique may prove particularly valuable if small tumors need to be removed that are difficult to detect with the naked eye. The humanized anti-carcinoembryonic antigen (anti-CEA) monoclonal antibody, labetuzumab (hMN-14), can be used as a tumor targeting agent in colorectal cancer (CRC), since CEA is overexpressed in approximately 95% of CRC. Dual-labeled labetuzumab, labeled with both a near-infrared fluorescent dye (IRDye800CW) and a radioactive label (Indium-111), can be used as a tracer for dual-modality imaging...

Bioimpedance measurements represent an advantageous method to evaluate the physio-pathological conditions of biological tissues and their use is spreading in different application fields, from the evaluation of body composition to the vital signs monitoring, passing through the individuation of cancer tissues and the detection of different substances (e.g. glucose measurements in people affected by diabetes). In fact, tissues electric properties vary with their conditions; for example, electrical conductivity increases when there is an inflammatory process, because of the presence of oedema, hyperaemia and infiltration...

Assay of multiple serum tumor markers such as carcinoembryonic antigen (CEA), cytokeratin 19 fragment antigen (CYFRA21-1), and neuron specific enolase (NSE), is important for the early diagnosis of lung cancer. Dickkopf-1 (DKK1), a novel serological and histochemical biomarker, was recently reported to be preferentially expressed in lung cancer. Four target proteins were sandwiched by capture antibodies attached to microarrays and detection antibodies carried on modified gold nanoparticles. Optical signals generated by the sandwich structures were amplified by gold deposition with HAuCl4 and H2O2, and were observable by microscopy or the naked eye...
