Resistance to 1st or 2nd generation epidermal growth factor receptor (EGFR) - tyrosine kinases (TKIs) develops predominantly due to an acquired mutation, EGFR T790M. Third-generation EGFR-TKIs have demonstrated potent activity against TKI resistance mediated by EGFR T790M. Thus, it become critical to identify T790M mutation on disease progression. Analysis of tumor tissue biopsy material is considered as gold standard for mutation detection. However, lung re-biopsy in a progressed patient involves several challenges - access to tumor, patient's willingness, safety, cost...

The epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) have revolutionized the treatment of EGFR-mutant nonsmall cell lung cancer (NSCLC). These EGFR TKIs demonstrate a different adverse event (AE) profile as compared to conventional chemotherapy agents. They are more commonly associated with cutaneous AEs and diarrhea while hematological AEs occurred commonly with chemotherapy agents. These AEs are the extension of pharmacological effect and occur as a result of blockade of EGFR-regulated pathways in the skin and gastrointestinal tract...

Lung cancer is one of the major causes of mortality worldwide and is on the rise in India. The identification of epidermal growth factor receptor (EGFR) mutations in nonsmall cell lung cancer (NSCLC) has paved the way for personalized therapy in lung cancer with EGFR-tyrosine kinase inhibitors (TKIs). Despite the proven efficacy of EGFR-TKIs in patients harboring EGFR mutations, their clinical utility is limited by the development of acquired resistance mechanisms by the tumor cells. T790M mutation accounts for 60% of all resistance mechanisms to EGFR TKIs and is responsible for treatment failure with first- and second-generation TKIs...

Metastases to central nervous system (CNS) are very common in nonsmall cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR)-positive mutation. Brain is the most affected part of CNS where blood-brain barrier (BBB) presents a challenge to currently available chemotherapeutic agents as well as first- (erlotinib and gefitinib) and second (afatinib)-generation EGFR tyrosine kinase inhibitors (TKIs) due to their poor penetrability. A rapid development of EGFR T790M secondary mutation is another cause of treatment failure, and patients tend to progress despite initial response to first- and second-generation EGFR TKIs...

Advanced nonsmall cell lung cancer (NSCLC) treatment is primarily based on platinum-based chemotherapy. Although epidermal growth factor receptor (EGFR) targeting has shifted the treatment paradigm toward personalized tyrosine kinase inhibitors (TKIs), resistance develops inevitably and EGFR T790M is the most common acquired resistance mechanism. Rebiopsy of resistant NSCLC cases can provide additional information on the underlying resistant mechanisms and therefore can help clinicians in taking better management decisions...

More than 50% of non-small cell lung cancer (NSCLC) cases harbor an actionable mutation, and molecular testing at different intervals can help in personalized and targeted treatment. Core tissue biopsy and needle biopsy done at the time of diagnosis/disease progression are interventional, time-consuming and can affect the patients adversely. Noninterventional biomarker testing by liquid biopsy promises to revolutionize advanced stage cancer screening. The present report was formulated based on an expert panel meeting of renowned oncologists who gave their opinions for minimally invasive liquid biopsy to detect targetable molecular biomarkers in advanced NSCLC cases...

Non-small cell lung cancer (NSCLC) accounts for the majority of primary lung cancer cases worldwide. The activating mutations of epidermal growth factor receptor (EGFR) have been demonstrated to associate with the development of NSCLC, with T790M mutation being the most common. Over the years, EGFR tyrosine kinase inhibitors (TKIs) were developed to target EGFR-related mutations. However, patients with activating EGFR mutations who are initially responsive to EGFR-TKIs eventually develop acquired resistance after a median progression-free survival of 10-16 months, followed by disease progression...

Patients with non-small cell lung cancer (NSCLC) commonly harbor epidermal growth factor receptor (EGFR) mutation. Due to the complex disease pathology, early-stage diagnosis of patients with EGFR mutation is essential to make appropriate treatment decision. Tyrosine kinase inhibitors (TKIs) are commonly used for their treatment, but almost half of the patients with EGFR mutation do not respond to the available TKIs and develop acquired resistance owing to T790M mutation. The presence of T790M mutation also warrants a robust diagnostic method so as to allow clinicians to modify cancer treatment...

Nonsmall cell lung cancer (NSCLC) is increasingly being treated with targeted therapies. Epidermal growth factor receptor (EGFR) has been extensively studied in NSCLC as an oncogenic driver. However, the efficacy of the EGFR tyrosine kinase inhibitors (TKIs) is adversely impacted by the development of resistance. The occurrence of de novo resistance to EGFR TKIs is attributed to multiple mechanisms such as point mutations of oncogenes and chromosomal rearrangements. The development of acquired resistance to EGFR TKIs is facilitated by secondary mutations, phenotypical transformation, aberrance of downstream pathways, and activation of alternate signaling pathways...
