Radiotherapy is one of the most effective treatment strategies for solid malignancies, including head-and-neck tumors (HNT). Oral mucositis is the most frequent, often dose-limiting early adverse event of radio(chemo)therapy for HNT. The oral mucosal response is - like that of typical turnover tissues - based on radiation-induced impairment of epithelial proliferation and cell production, in face of ongoing physiological cell differentiation and cell loss, consequently resulting in hypoplasia and eventually mucosal ulceration...

Targeting the androgen receptor (AR) pathway prolongs survival in patients with prostate cancer, but resistance rapidly develops. Understanding this resistance is confounded by a lack of noninvasive means to assess AR activity in vivo. We report intracellular accumulation of a secreted antigen-targeted antibody (SATA) that can be used to characterize disease, guide therapy, and monitor response. AR-regulated human kallikrein-related peptidase 2 (free hK2) is a prostate tissue-specific antigen produced in prostate cancer and androgen-stimulated breast cancer cells...

: Erdheim-Chester disease is a histiocytic neoplasm of diseases from the group of non-Langerhans-cell histiocytoses, formed by infiltrates of foamy histiocytes. These pathological histiocytes produce pro-inflammatory cytokines. Therefore Erdheim-Chester disease is called inflammatory histiocytary neoplasm. The disease is accompanied by clinical symptoms of systemic inflammatory response, i.e. B symptoms. Imaging examinations detect typical osteosclerotic changes affecting diaphyses and metaphyses of the lower long bones and fibrotic changes which affect the aorta wall and the vessels leading from it...

More than 800 oesophageal tumours are diagnosed each year in Hungary. The disease is characterized by high mortality. The curative treatment traditionally surgical, although the study results of recent decades pointed out that patient outcome can be improved with the proper application of radio- and chemotherapy. The diverse study designs, the low number of recruited patients and the sometimes conflicting results make the determination of optimal treatment difficult. The aim of this work is to facilitate the choice of treatment modality with the best outcome, especially with the view of medical oncologists...

Contrast enhancement of glioblastomas (GBM) is caused by the decrease in relaxation time, T1. Here, we demonstrate that the quantitative measurement of T1 (qT1) discovers a subtle enhancement in GBM patients that is invisible in standard MRI. We assessed the volume change of this "cloudy" enhancement during radio-chemotherapy and its impact on patients' progression-free survival (PFS). We enrolled 18 GBM patients in this observational, prospective cohort study and measured 3T-MRI pre- and post contrast agent with standard T1-weighted (T1w) and with sequences to quantify T1 before radiation, and at 6-week intervals during radio-chemotherapy...

Head and neck squamous cell carcinoma (HNSCC) is one of the most common solid cancers worldwide. It is mainly caused by exposure to tobacco smoke and alcohol as well as infection with the human papilloma virus (HPV). The prognosis is poor, especially once it recurs or metastasizes. Current therapeutic options include surgery, radio- and chemotherapy. Epidermal growth factor receptor (EGFR) inhibitors are so far the only targeted agents that have been approved in head and neck cancer. Primary or secondary resistance is frequent or will eventually develop...

Although motor learning theory has led to evidence-based practices, few trials have revealed the superiority of one theory-based therapy over another after stroke. Nor have improvements in skills been as clinically robust as one might hope. We review some possible explanations, then potential technology-enabled solutions. Over the Internet, the type, quantity, and quality of practice and exercise in the home and community can be monitored remotely and feedback provided to optimize training frequency, intensity, and progression at home...

Radio (chemo) therapy is a crucial treatment modality for head and neck squamous cell carcinoma (HNSCC), but relapse is frequent, and the underlying mechanisms remain largely elusive. Therefore, novel biomarkers are urgently needed. Previously, we identified gains on 16q23-24 to be associated with amplification of the Fanconi anemia A (FancA) gene and to correlate with reduced progression-free survival after radiotherapy. Here, we analyzed the effects of FancA on radiation sensitivity in vitro, characterized the underlying mechanisms, and evaluated their clinical relevance...

Conventional therapeutics are often frequented with recurrences, refraction and regimen resistance in oral cavity cancers which are predominantly manifested by cancer stem cells (CSCs). During oncoevolution, cancer cells may undergo structural and functional reprogramming wherein they evolve as highly tolerant CSC phenotypes with greater survival advantages. The CSCs possess inherent and exclusive properties including self-renewal, hierarchical differentiation, and tumorigenicity that serve as the basis of chemo-radio-resistance in oral cancer...

Patients with unresectable hepatocellular carcinoma (HCC) usually have poor prognosis because current monotherapy including surgery, chemotherapy and radiotherapy (RT) are not effective. Combination therapy may be effective to overcome this clinical problem. Here, we proposed the combination of sorafenib and RT, which have been applied in HCC treatment, could improve the treatment outcome of HCC. Our previous study showed that sorafenib could suppress the expression of NF-κB which is related to the chemo- and radio-resistance...

In this study, the radiocomplexation of risedronic acid, a potent bisphosphonate with a no carrier added (NCA) (177) Lu, was investigated and followed by quality control studies, biodistribution evaluation, and dosimetry study for human based on biodistribution data in Wistar rats. The moderate energy β(-) emitter, (177) Lu (T½  = 6.7 days, Eβmax  = 497 keV), has been considered as a potential agent for development of bone-seeking radiopharmaceuticals. Because the specific activity of the radiolabeled carrier molecules should be high, the NCA radionuclides have an effective role in nuclear medicine...

BACKGROUND: Individual variability in prognosis of esophageal cancer highlights the need for advances in personalized therapy. This systematic review aimed at elucidating the prognostic role of gene expression profiles and at identifying gene signatures to predict clinical outcome. METHODS: A systematic search of the Medline, Embase and the Cochrane library databases (2000-2015) was performed. Articles associating gene expression profiles in patients with esophageal adenocarcinoma or squamous cell carcinoma to survival, response to chemo(radio)therapy and/or lymph node metastasis were identified...

By using radio-labeled multifunctional superparamagnetic iron oxide nanoparticles (SPIONs) and an alternating magnetic field (AMF), we carried out targeted hyperthermia, drug delivery, radio-immunotherapy (RIT), and controlled chemotherapy of cancer tumors. We synthesized and characterized Indium-111-labeled, Trastuzumab and Doxorubicin (DOX)-conjugated APTES-PEG-coated SPIONs in our previous work. Then, we evaluated their capability in SPECT/MRI (single photon emission computed tomography/magnetic resonance imaging) dual modal molecular imaging, targeting, and controlled release...

EGFR (epidermal growth factor receptor) targeted therapy has shown great success in clinical comparing with chemotherapy in EGFR mutation NSCLCs. Such as, gefitinib, first generation EGFR TKI, has obviously prolonged the FPS (progression free survival) of the subgroup of patients, but to those who did not get a certain mutation in EGFR kinase domain, the outcome is poor. In view of this situation, scientists have synthesized many radiotracers for selecting the right people by PET/CT imaging to NSCLC TKI therapy...

BACKGROUND: Suspected recurrence of thyroid carcinoma is a diagnostic challenge when findings of both a radio iodine whole body scan and ultrasound are negative. PET/CT and MRI have shown to be feasible for detection of recurrent disease. However, the added value of a consensus reading by the radiologist and the nuclear medicine physician, which has been deemed to be helpful in clinical routines, has not been investigated. This study aimed to investigate the impact of combined FDG-PET/ldCT and MRI on detection of locally recurrent TC and nodal metastases in high-risk patients with special focus on the value of the multidisciplinary consensus reading...

Colorectal cancer is the most common malignancy of the gastrointestinal tract. Surgical treatment combined with radiotherapy is the main treatment course for colorectal cancer; nevertheless, radio-resistance is commonly encountered during the treatment course and seriously influences the therapeutic efficacy. We tested the hypothesis that the CXCL12/CXCR4 axis is closely related to radiotherapy sensitivity in colorectal cancer cells. Here, we found that the decrease in cell viability and the increase in cell death induced by radiotherapy were attenuated by CXCL12 treatment, and the inhibition of CXCR4 promoted colorectal cancer cells to be more sensitive to radiotherapy...
