The invention relates to methods of in situ detection of a nucleic acid variation of a target nucleic acid in a sample, including single nucleotide variations, multi-nucleotide variations or splice sites. The method can comprise the steps of contacting the sample with a probe that detects the nucleic acid variation or splice site and a neighbor probe; contacting the sample with pre-amplifiers that bind to the nucleic acid variation probe or splice site probe and neighbor probe, respectively; contacting the sample with a collaboration amplifier that binds to the pre-amplifiers; and contacting the sample with a label probe system, wherein hybridization of the components forms a signal generating complex (SGC) comprising a target nucleic acid with the nucleic acid variation or splice site, the probes and amplifiers; and detecting in situ signal from the SGC on the sample. The invention also provides samples, tissue slides, and kits relating to detection of nucleic acid variations, including single nucleotide variations, multi-nucleotide variations or splice sites, of a target nucleic acid.

Methods of detecting nucleic acids, including methods of detecting two or more nucleic acids in multiplex branched-chain DNA assays, are provided. Nucleic acids captured on a solid support are detected, for example, through cooperative hybridization events that result in specific association of a label with the nucleic acids. Compositions, kits, and systems related to the methods are also described.

DESCRIPTION provided by applicant In the US lung cancer will add new cases and cause deaths in Non small cell lung cancer NSCLC accounts for of lung cancer The availability of targeted therapies directed to driver oncogenes such as EGFR mutations and gene fusions e g EML ALK in recent years has transformed the management of NSCLC These advances have also created an unprecedented challenge to conduct multiple molecular testing using limited diagnostic materials In many settings of NSCLC patients present with advanced disease and are simultaneously diagnosed staged and their tumors molecularly tested for targeted therapy using fine needle aspiration FNA derived cytology specimen obtained during endobronchial ultrasound EBUS Liquid based cytology slides especially ThinPrep slides have proven superior to formalin fixed paraffin embedded FFPE cell blocks for assessing ALK gene status by DNA fluorescent in situ hybridization FISH However the number of ThinPrep slides that can be prepared from a typical EBUS FNA specimen is limited usually In order to perform multiple testing an in situ method with multiplexing capability beyond conventional FISH and immunohistochemistry IHC is needed In this Phase I study we propose to leverage the high sensitivity and multiplexing capability of a recently developed RNA in situ hybridization technology RNAscope R to develop a novel companion diagnostic algorithm that can efficiently and accurately detect multiple rare but andquot actionableandquot oncogenic gene fusions ALK ROS RET NTRK and others in NSCLC patients using FNA derived ThinPrep slides PUBLIC HEALTH RELEVANCE The current increasing use of minimally invasive diagnostic procedures in oncology poses a number of challenges to companion diagnostic testing First while the number of molecular targets to be tested is increasing on a regular basis the amount of diagnostic specimen is decreasing Second most of the molecular changes of interest are present only in small subsets of patients Therefore there is an urgent need to develop molecular diagnostic methods that have multiplexing capability beyond conventional fluorescent in situ hybridization FISH and immunohistochemistry IHC yet maintain the benefits of in situ biomarker detection In this Phase I study we propose to leverage the high sensitivity and multiplexing capability of the RNAscope RNA ISH technology to develop a novel companion diagnostic algorithm that can efficiently and accurately detect multiple rare but andquot actionableandquot oncogenic fusions in non small cell lung cancer NSCLC using limited fine needle aspiration FNA derived cytology samples
