Abstract
Brain metastases (BMs) represent the most common intracranial tumors in adults, and most commonly originate from lung, followed by breast, melanoma, kidney, and colorectal cancer. Management of BM is individualized based on the size and number of brain metastases, the extent of extracranial disease, the primary tumor subtype, neurological symptoms, and prior lines of therapy. Until recently, treatment strategies were limited to local therapies, like surgical resection and radiotherapy, the latter in the form of whole-brain radiotherapy or stereotactic radiosurgery. The next generation of local strategies includes laser interstitial thermal therapy, magnetic hyperthermic therapy, post-resection brachytherapy, and focused ultrasound. New targeted therapies and immunotherapies with documented intracranial activity have transformed clinical outcomes. Novel systemic therapies with intracranial utility include new anaplastic lymphoma kinase inhibitors like brigatinib and ensartinib; selective "rearranged during transfection" inhibitors like selpercatinib and pralsetinib; B-raf proto-oncogene inhibitors like encorafenib and vemurafenib; Kirsten rat sarcoma viral oncogene inhibitors like sotorasib and adagrasib; ROS1 gene rearrangement (ROS1) inhibitors, anti-neurotrophic tyrosine receptor kinase agents like larotrectinib and entrectinib; anti-human epidermal growth factor receptor 2/epidermal growth factor receptor exon 20 agent like poziotinib; and antibody-drug conjugates like trastuzumab-emtansine and trastuzumab-deruxtecan. This review highlights the modern multidisciplinary management of BM, emphasizing the integration of systemic and local therapies.

Abstract
Lung cancer is considered one of the most fatal malignant neoplasms because of its late detection. Detecting molecular markers in samples from routine bronchoscopy, including many liquid-based cytology procedures, such as bronchoalveolar lavage fluid (BALF), could serve as a favorable technique to enhance the efficiency of a lung cancer diagnosis. BALF analysis is a promising approach to evaluating the tumor progression microenvironment. BALF's cellular and non-cellular components dictate the inflammatory response in a cancer-proliferating microenvironment. Furthermore, it is an essential material for detecting clinically significant predictive and prognostic biomarkers that may aid in guiding treatment choices and evaluating therapy-induced toxicities in lung cancer. In the present article, we have reviewed recent literature about the utility of BALF analysis for detecting markers in different stages of tumor cell metabolism, employing either specific biomarker assays or broader omics approaches.

Abstract
Introduction: Osimertinib is currently the only FDA- and EMA-approved third-generation small-molecule epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI). It was initially indicated for second-line treatment of patients with metastatic EGFR T790M mutation-positive non-small cell lung cancer (NSCLC) and got approved for first-line treatment of EGFR activation mutation-positive metastatic NSCLC in 2018. Most recently, the FDA granted approval for the adjuvant treatment of patients with early-stage mutated EGFR NSCLC after tumor resection.Areas covered: This drug discovery case history focuses on the key studies that led to the preclinical discovery and development of osimertinib. The authors focus on published preclinical studies by scientists from AstraZeneca and highlight key events in the clinical development.Expert opinion: Although eventually compromised by the cellular plasticity of the tumor and the inevitable acquisition of drug resistance through the use of osimertinib, its key role in the treatment of NSCLC with specific EGFR mutations will be maintained in the near future. As the genome of EGFR is highly labile and since the rapid development of new mutants remains an issue, there is still room for improvement for the next generation of inhibitors.

Abstract
BACKGROUND Osimertinib is a standard therapy for advanced non-small cell lung cancer (NSCLC) patients with an acquired epidermal growth factor receptor (EGFR) T790M mutation; however, the exploration of clinical characteristics that may affect prognosis and long-term survival is still lacking. OBJECTIVE This retrospective study aimed to provide long-term survival data and explore meaningful prognostic factors in patients treated with osimertinib. PATIENTS AND METHODS A total of 246 patients with acquired EGFR T790M mutation who were treated with osimertinib were included in this study. Progression-free survival (PFS), overall survival from osimertinib initiation (OS1), overall survival from diagnosis of advanced disease (OS), and possible prognostic clinical features were analyzed. RESULTS The median PFS, OS1, and OS values were 12.17, 24.33, and 47.86 months, respectively. The median PFS of patients harboring EGFR exon 19 deletions/T790M (19del/T790M) and those harboring EGFR 21 L858R/T790M were 13.27 and 9.77 months (p = 0.001), respectively, while the median OS1 values were 25.03 and 18.30 months (p = 0.023), respectively; however, no significant difference was found in median OS (p = 0.060). Cox regression analysis revealed that coexisting mutation type and extrathoracic metastasis affected survival (PFS, OS1). In addition, gene biopsy specimen type (tissue or blood sample) was related to PFS (p = 0.032), which implied that liquid biopsy may be an independent poor prognostic factor. CONCLUSIONS This is the first reported survival analysis of osimertinib-treated Chinese patients, which indicates a median OS of 47.86 months. The EGFR T790M mutation is likely to coexist with 19del and indicate longer PFS and OS1 than EGFR 21 L858R/T790M. Additionally, the extrathoracic metastasis status and biopsy specimen type might also affect the survival of patients treated with osimertinib.

Abstract
There were many clinical studies on lung cancer in 2018. In particular, significant progress has been made in immunotherapy and targeted therapy. Whether in small cell lung cancer (SCLC) or non-small cell lung cancer (NSCLC), immune checkpoint inhibitors (ICIs) have shown good results. For patients with specific gene mutations, the new generation inhibitors also showed good results in clinical trials. In this review, we summarize the clinical trials in lung cancer in 2018 and describe the progress and prospects for lung cancer therapies.

Efficacy of osimertinib for the treatment of previously EGFR TKI treated NSCLC patients: a meta-analysis. Clin Transl Oncol 2019; 22:892-899. [PMID: 31538306 DOI: 10.1007/s12094-019-02204-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2019] [Accepted: 08/31/2019] [Indexed: 10/26/2022]
Abstract
BACKGROUND This study evaluates the efficacy of osimertinib for the treatment of previously epidermal growth factor receptor tyrosine kinase inhibitors (EFGR-TKI) treated non-small cell lung cancer (NSCLC) patients. METHOD Research articles reporting the efficacy of osimertinib for NSCLC patients were identified from literature databases (Embase, Ovid, PubMed and Scopus) by following pre-determined eligibility criteria. Response and survival data were extracted from study reports and were pooled under random-effects model to obtain overall/subgroup effect sizes of selected efficacy outcomes. RESULTS Nine studies (950 patients; age 60.1 years [95% confidence interval: 57.2, 63.1]; 65% [95% CI: 62, 69] females; 69% [35, 100] with T790M; 61% [53, 68] with ex19del; and 35% [29, 41] with L858R mutations). Osimertinib treatment was associated with a PFS of 11.17 months [7.80, 14.55] which was longer in treatment-naïve (20.30 [15.37, 25.23]) than in prior EGFR-TKI-treated (10.20 [9.60, 10.80]) patients. 1-year survival was 81.29% [73.25, 89.32]. Complete response rate was 1.48% [1.19, 1.76]. PR was achieved in 53.18% [24.18, 82.18] patients which differed between treatment-naïve and prior EGFR-TKI-treated patients (74.48 [65.59, 83.37] and 67.99% [62.68, 73.30], respectively. Objective response rate and disease control rates were 69.80% [64.84, 74.77] and 92.43% [89.42, 95.43], respectively, which did not differ between treatment-naïve and prior EGFR-TKI-treated patients. CONCLUSION Osimertinib treatment yields approximately 10 months PFS in prior EGFR-TKI-treated and 20 months in treatment-naïve NSCLC patients. Partial response rate is also higher in treatment-naïve patients. However, objective response rate (ORR) and disease control rate (DCR) did not differ between groups of patients.

Abstract
Osimertinib is a potent, irreversible epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) selective for EGFR‑TKI sensitizing (EGFRm) and T790M resistance mutations. The primary objective of the cytology cohort in the AURA study was to investigate safety and efficacy of osimertinib in pretreated Japanese patients with EGFR T790M mutation‐positive non‐small cell lung cancer (NSCLC), with screening EGFR T790M mutation status determined from cytology samples. The cytology cohort was included in the Phase I dose expansion component of the AURA study. Patients were enrolled based on a positive result of T790M by using cytology samples, and received osimertinib 80 mg in tablet form once daily until disease progression or until clinical benefit was no longer observed at the discretion of the investigator. Primary endpoint for efficacy was objective response rate (ORR) by investigator assessment. Twenty‐eight Japanese patients were enrolled into the cytology cohort. At data cut‐off (February 1, 2016), 12 (43%) were on treatment. Investigator‐assessed ORR was 75% (95% confidence interval [CI] 55, 89) and median duration of response was 9.7 months (95% CI 3.8, not calculable [NC]). Median progression‐free survival was 8.3 months (95% CI 4.2, NC) and disease control rate was 96% (95% CI 82, 100). The most common all‐causality adverse events were paronychia (46%), dry skin (46%), diarrhea (36%) and rash (36%). Osimertinib provided clinical benefit with a manageable safety profile in patients with pretreated EGFR T790M mutation‐positive NSCLC whose screening EGFR T790M mutation‐positive status was determined from cytology samples.
