Aim Of Study: To determine a diagnostic algorithm for detecting translocation of the gene and its frequency in the Moscow region.

Materials And Methods: During the priod between 2014 and 2018 (inclusive), 488 patients without activating mutations in the gene in the Moscow region were tested. To detect translocation of the ALK gene, fluorescence hybridization (FISH) methods, an immunohistochemical method, and, in some cases, a polymerase chain reaction were used.

Results: Revealed gene rearrangement in a population of patients with lung adenocarcinoma amounted to an average of 7.6% of cases. With this, the main method that we used was immunohistochemical method, applicable in more than 80% of cases. The use of other methods for verification of abnormalities in the gene was found necessary in rare cases (3.3%).

Conclusions: Using the algorithm presented in the article, it was possible to detect gene rearrangement in a population of patients with lung adenocarcinoma in the Moscow region in an average of 7.6% of cases.

Objective: ALK, ROS1, NTRK, and RET gene fusions and MET exon 14 skipping alterations represent fundamental predictive biomarkers for advanced non-small cell lung cancer (NSCLC) patients to ensure the best treatment choice. In this scenario, RNA-based NGS approach has emerged as an extremely useful tool for detecting these alterations. In this study, we report our NGS molecular records on ALK, ROS1, NTRK, and RET gene fusions and MET exon 14 skipping alterations detected by using a narrow RNA-based NGS panel, namely SiRe fusion.

Introduction: This study aimed to assess the feasibility of implementing the Idylla system, an ultra-rapid, cartridge-based assay, as an extension of rapid on-site evaluation (ROSE) in cytology. The authors conducted a pilot validation study on specimens from non-small cell lung carcinoma, thyroid carcinoma, and melanoma, evaluating four assays designed to detect alterations in KRAS, EGFR, BRAF, gene fusions, and expression imbalances in ALK, ROS1, RET, NTRK1/2/3, and MET exon 14 skipping transcripts. They investigated the feasibility of providing accurate biomarker molecular testing results in a cytopathology laboratory within hours of specimen collection.

Background: Anaplastic lymphoma kinase () rearrangement, the most common oncogenic rearrangement in lung adenocarcinoma, occurs in approximately 5% of non-small cell lung cancer (NSCLC) patients. gene is the most common partner of rearrangement, and distinct EML4-ALK fusions differ in their responsiveness to ALK tyrosine kinase inhibitors. However, the concurrence of two rearrangements in one patient and whose response to ALK-TKIs have rarely been reported so far.

Article Synopsis
  • Driver mutations in tyrosine kinases like ALK are important in non-small cell lung cancer but uncommon in large cell neuroendocrine carcinoma (LCNEC).
  • A 55-year-old woman with a history of breast cancer developed advanced LCNEC 10 years later, exhibiting multiple brain metastases and testing positive for the ALK fusion gene, leading to treatment with lorlatinib.
  • The patient showed a significant tumor reduction after 6 weeks of lorlatinib therapy, indicating that ALK-positive advanced LCNEC might respond well to this treatment, especially for brain metastases.
