PURPOSE: Symptomatic adverse event (AE) monitoring is essential in cancer clinical trials to assess patient safety, as well as inform decisions related to treatment and continued trial participation. As prior research has demonstrated that conventional concordance metrics (e.g., intraclass correlation) may not capture nuanced aspects of the association between clinician and patient-graded AEs, we aimed to characterize differences in AE grading thresholds between doctors (MDs), registered nurses (RNs), and patients using the Bayesian Graded Item Response Model (GRM)...

PURPOSE: The genomic break on the major breakpoint cluster region of chromosome 22 results in two BCR-ABL1 transcripts of different sizes, e14a2 and e13a2. Favorable survival probabilities of patients with chronic myeloid leukemia (CML) in combination with too small patient samples may yet have obstructed the observation of differences in overall survival of patients according to transcript type. To overcome potential power problems, overall survival (OS) probabilities and probabilities of CML-related death were analyzed in 1494 patients randomized to first-line imatinib treatment...

PURPOSE: Breast cancer is a significant global public health issue. It is the leading cause of death among women around the world, with an incidence increasing annually. In recent years, there has been more and more information in the literature regarding a protective role of vitamin D in cancer. Increasingly preclinical and clinical studies suggest that vitamin D optimal levels can reduce the risk of breast cancer development and regulate cancer-related pathways. METHOD: In this review, we focus on the importance of vitamin D in breast cancers, discussing especially the influence of vitamin D signaling on estrogen receptor and human epidermal growth factor receptor 2 (HER2), two major biomarkers of breast cancer today...

INTRODUCTION: Thyroid cancer (TC), follicular adenoma (FA) and Hashimoto's thyroiditis (HT) are three of the most frequently reported abnormalities that affect the thyroid gland. A frequent co-occurrence along with similar histopathological features is observed between TC and FA as well as between TC and HT. The conventional diagnostic methods such as histochemical analysis present complications in differential diagnosis when these abnormalities occur simultaneously. Hence, the authors recognize novel methods based on screening genetic defects of thyroid abnormalities as viable diagnostic and prognostic methods that could complement the conventional methods...

BACKGROUND: Sentinel node (SN) biopsy is regarded as standard of care for patients (pts) with cutaneous melanoma ≥1.0 mm of thickness. In the recent AJCC classification, findings in the SN are simply classified as positive or negative. In our analyses, we were interested whether quantitative real-time PCR (qRT-PCR) is able to predict disease-free survival (DFS) and overall survival (OS) depending on tumour burden in the SN. METHODS: One hundred and forty-five pts were analysed using qRT-PCR for tyrosinase...

BACKGROUND: TERT promoter mutations were detected at high frequencies in several cancer types including melanoma. Previous reports showed that these recurrent mutations increase TERT gene expression and the use of TERT mutation status as prognostic factor was suggested. OBJECTIVES: Here we screen a panel of 115 melanoma tumor samples from Austrian patients to evaluate the prevalence and distribution of TERT promoter mutations. The association with clinical and tumor characteristics and the effect on overall survival was analyzed...

BACKGROUND: Fingerprints have long been used for personal identification; however, some case reports suggested that some chemotherapy agents such as paclitaxel lead to fingerprints loss due to hand-and-foot syndrome (HFS). METHODS: This case-control study was performed on 65 patients who received chemotherapy regimens with/without paclitaxel. Patients with the history of receiving any drugs with significant HFS adverse effect or patients with any conditions that affect fingerprints were excluded...

PURPOSE: Gastric cancer remains a major health concern, and improvement of the therapeutic options is crucial. Treatment with targeted therapeutics such as the EGFR-targeting antibody cetuximab or the HER2-targeting antibody trastuzumab is either ineffective or moderately effective in this disease, respectively. In this study, we analysed the involvement of the HER receptor ligands amphiregulin (AREG), epidermal growth factor (EGF), heparin-binding epidermal growth factor (HB-EGF) and transforming growth factor alpha (TGFα) in the responsiveness of gastric cancer cell lines to cetuximab and trastuzumab...

BACKGROUND: Autophagy can function in a dual role in cancer development and progression: It can be cytoprotective or contribute to cell death. Therefore, determining the contextual role of autophagy between these two opposing effects is important. So far, little is known about the role of autophagy in uveal melanoma. In the present study, we looked to investigate the autophagic process, as well as its effect on cell survival in uveal melanoma cell lines under stressed conditions (starvation)...
