BACKGROUND: Recent advances in sequencing technologies supported the development of molecularly targeted therapy in cancer patients. Thus, genomic analyses are becoming a routine part in clinical practice and accurate detection of actionable mutations is essential to assist diagnosis and therapy choice. However, this is often challenging due to major problems associated with DNA from formalin-fixed paraffin-embedded tissue which is usually the primary source for genetic testing. OBJECTIVES: Here we want to share our experience regarding major problems associated with FFPE DNA used for PCR-based sequencing as illustrated by the mutational analysis of ERBB4 in melanoma...

Optimal adherence to CML therapy is of key importance to maximize treatment effectiveness. Two clinical studies (ADAGIO and Hammersmith) have proven a clear correlation between adherence and achieving optimal treatment response and have revealed that non-adherence is common in CML patients (Marin et al. in J Clin Oncol 28(24):2381-2388, 2010, Noens et al. in Haematologica 99(33):437-447, 2014). The aim of this study is to assess the extent of suboptimal adherence and to investigate motivations and behavioural patterns of adherence in a worldwide patient sample...

PURPOSE: Glucocorticoids (GCs) are of wide usage in the clinical treatment of lymphoblastic malignancies such as acute lymphoblastic leukemia. However, individually distinctive responsiveness to the GC therapy may attenuate their clinical efficacy, and more reliable predictor for GC resistance is still eagerly needed. Recent studies indicate that microRNAs (miRNAs), which demonstrate regulatory functions targeting mRNAs during the post-transcription, involved in the regulation of GCs sensitivity through several mechanisms, especially adjusting the magnitude of GC receptors (GRs), which mediates the cellular effects of GCs and plays a pivotal role in GCs sensitivity, inspiring that special miRNAs pattern could serve as the biomarkers to predict GC sensitivity and bring forth potential strategies for overcoming drug resistance...

Valid HER2 testing is essential for optimal therapy of patients with HER2-positive gastric cancer and the correct use of first-line chemotherapy. While testing for HER2 status in breast cancer is routinely performed, this is not the case for HER2 testing in gastric cancer and it is usually only performed on clinician request. An interdisciplinary German expert group (pathologists and clinicians) took the challenges of HER2 testing in gastric cancer as an opportunity to address essential aspects and questions for the practical use of HER2 testing in this indication...

PURPOSE: Most randomized clinical trials evaluating second generation tyrosine kinase inhibitors (TKI) for the first-line treatment of Chronic Myeloid Leukemia used as comparator the 'standard' dose of 400 mg imatinib daily. Several studies showed higher rates of major molecular remission (MMR) at 12 months with 800 mg compared to 400 mg, suggesting that high-dose imatinib may be the appropriate comparator rather than 400 mg. METHODS: We systematically reviewed randomized trials comparing the two dosages, calculated a common estimator and compared the result to a common estimator of trials evaluating a second generation TKI in comparison with 400 mg imatinib daily...

PURPOSE: The therapy of unresectable advanced thyroid carcinomas shows unfavorable outcome. Constitutive nuclear factor-κB (NF-κB) activation in thyroid carcinomas frequently contributes to therapeutic resistance; the radioiodine therapy often fails due to the loss of differentiated functions in advanced thyroid carcinomas. Curcumin is known for its anticancer properties in a series of cancers, but only few studies have focused on thyroid cancer. Our aim was to evaluate curcumin's molecular mechanisms and to estimate if curcumin could be a new therapeutic option in advanced thyroid cancer...
