EML4-ALK-positive lung adenocarcinoma presenting an unusual metastatic pattern in a 29-year-old woman who is alive and well in her third year follow up:A case report

Non-small cell lung cancer (NSCLC) is a frequent tumor entity with high mortality. Although several newly discovered chromosomal translocations and mutations opened new horizons for targeted therapy, literature still lacks large series of NSCLC with chromosomal abberations and their correlations with histological and clinical features. We present a case of echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) translocation positive adenocarcinoma of the lung with an unusual metastatic pattern in a 29-year-old young woman. Conclusion: Young adult non-smoker female patients with an unexplained pleural effusion and signs of metastatic disease should alert the physicians straight away for all types of malignancies including lung cancer. Any skin lesions should be evaluated carefully, biopsies should be done to exclude metastasis in urgency. On the other hand, an uncommon clinical presentation of a lung cancer requires corresponding molecular testing rapidly in order to offer the best treatment option

Clinical Utility of Functional RNA Analysis for the Reclassification of Splicing Gene Variants in Hereditary Cancer

Background: Classification of splicing variants (SVs) in genes associated with hereditary cancer is often challenging. The aim of this study was to investigate the occurrence of SVs in hereditary cancer genes and the clinical utility of RNA analysis. Material and Methods: 1518 individuals were tested for cancer predisposition, using a Next Generation Sequencing ( NGS) panel of 36 genes. Splicing variant analysis was performed using RT-PCR and Sanger Sequencing. Results: In total, 34 different SVs were identified, 53% of which were classified as pathogenic or likely pathogenic. The remaining 16 variants were initially classified as Variant of Uncertain Significance (VUS). RNA analysis was performed for 3 novel variants. Conclusion: The RNA analysis assisted in the reclassification of 20% of splicing variants from VUS to pathogenic. RNA analysis is essential in the case of uncharacterized splicing variants, for proper classification and personalized management of these patients

Revisiting the Implications of Positive Germline Testing Results Using Multi-gene Panels in Breast Cancer Patients

Background/Aim: The use of multi-gene panels for germline testing in breast cancer enables the estimation of cancer risk and guides risk-reducing management options.The aim of this study was to present data that demonstrate the different levels of actionability for multi-gene panels used in genetic testing of breast cancer patients and their family members. Materials and Methods: We performed an analysis in our clinical database to identify breast cancer patients undergoing genetic testing. We reviewed positive results in respect of risk estimation and management, cascade family testing, secondary findings and information for treatment decision-making. Results: A total of 415 positive test reports were identified with 57.1%, 18.1%, 10.8% and 13.5% of individuals having pathogenic/likely pathogenic variants in high, moderate, low and with insufficient evidence for breast cancer risk genes, respectively. Six point seven percent of individuals were double heterozygotes. Conclusion: Germline findings in 92% of individuals are linked to evidence-based treatment information and risk estimates for predisposition to breast and/or other cancer types. The use of germline findings for treatment decision making expands the indication of genetic testing to include individuals that could benefit from targeted treatments
