The treatment of advanced lung adenocarcinoma with activating EGFR mutations.

Introduction: Lung adenocarcinomas account for approximately 40-50% of all NSCLC (Non-Small Cell Lung Cancer) cases. In addition, lung adenocarcinomas can harbor several different genetic mutations, EGFR (Epidermal Growth Factor Receptor) being the most frequent one, accounting for approximately 5-15% of all the mutations in western patients and for approximately 40-55% in Asian patients; on the other hand, EGFR mutations are uncommon in squamous histology. Approximately 90% of EGFR mutations are represented by exon 19 in-frame deletion and by the L858R exon 21-point mutation, that confer sensitivity to EGFR TKI (Tyrosine Kinase Inhibitors) treatment.

The role of nivolumab combined to immunotherapy and/or chemotherapy in the first-line treatment of advanced Non Small Cell Lung Cancer.

: One of the latest breakthroughs in the treatment of advanced Non Small Cell Lung Cancer (NSCLC) is represented by PD-1/PD-L1-targeting Immune Checkpoint Inhibitors (ICIs). However, only a limited subset of advanced NSCLC patients can receive first-line ICI monotherapy (advanced NSCLC patients without driver mutations and with a PD-L1 expression ≥50% or ≥1%) and naïve ICI-respondent patients represent an even more limited subgroup of patients, which eventually experience progression of disease after approximately 7-11 months. Therefore, different strategies are being evaluated to obtain a higher response rate and a more durable clinical response in this setting.

Liquid Biopsy Testing Can Improve Selection of Advanced Non-Small-Cell Lung Cancer Patients to Rechallenge with Gefitinib.

The ICARUS trial is a phase II, open label, multicenter, single arm study conducted to investigate the efficacy, safety, and tolerability of a rechallenge treatment with the first-generation tyrosine kinase inhibitor (TKI) gefitinib in advanced non-small-cell lung cancer (NSCLC) patients carrying activating mutations of the epidermal growth factor receptor (). The ICARUS trial enrolled 61 patients who were rechallenged with gefitinib at progression after second-line chemotherapy. Serum-derived circulating cell-free DNA (cfDNA) collected before the rechallenge from a cohort of 29 patients, was retrospectively analyzed for the exon 19 deletions and for the p.

The role of combination chemo-immunotherapy in advanced non-small cell lung cancer.

: Even with the currently recommended chemotherapeutic and immunotherapeutic treatment, the five year survival rate for advanced nonsquamous and squamous NSCLC without oncogenic drivers remains poor. However, several different chemo-immunotherapy combinations are presently being investigated - with favorable results- in order to increase the PFS and OS rates of these patients. : Therefore, this paper aims to discuss the most promising trials investigating chemo-immunotherapy combinations and their present and future impact on advanced NSCLC treatment paradigms.

First-line treatment of advanced non-small cell lung cancer with ALK rearrangement: state of the art and future development.

: Approximately 5% of all diagnosed non-small cell lung cancer (NSCLC) patients harbor a genetic rearrangement between the ALK and EML4 genes, representing a specific molecular, histological and clinical subgroup (ALK+ NSCLC). To date, upfront treatment with ALK-tyrosine-kinase inhibitors (ALK-TKIs) has replaced chemotherapy in the first line setting for this subset of patients with excellent results. However, all treated patients eventually develop acquired resistance mechanisms to these agents (mainly resistance mutations) and experience progression of the disease.

Safety and Tolerability of Anaplastic Lymphoma Kinase Inhibitors in Non-Small-Cell Lung Cancer.

The chimeric protein echinoderm microtubule-associated protein-like 4-anaplastic lymphoma kinase, resulting from the rearrangement of the homonym genes, is one of the currently targetable oncogenic drivers in anaplastic lymphoma kinase-positive non-small-cell lung cancer. In fact, four first- and second-generation anaplastic lymphoma kinase tyrosine kinase inhibitors, crizotinib (PF-02341066), ceritinib (LDK378), alectinib (CH5424802), and brigatinib (AP26113), are presently approved for clinical practice; however, these agents are not devoid of complications and thus should be administered meaningfully. Furthermore, third-generation inhibitors are currently under development to overcome acquired resistance mechanisms inevitably resulting from treatment with first- and second-generation tyrosine kinase inhibitors.

Advanced Non-Small Cell Lung Cancer with Activating Epidermal Growth Factor Receptor Mutation: First Line Treatment and Beyond.

Background: Lung cancer is the leading cause of cancer mortality, being responsible for more than 1.6 million deaths each year worldwide and non-small-cell lung cancer (NSCLC) accounts for approximately 85% of lung cancers; moreover, 10 to 15% of all NSCLCs harbor EGFR (epidermal growth factor receptor) activating mutations, being suitable for EGFR-Tyrosine Kinase Inhibitors (TKI) molecular targeted therapy. However, EGFR+ NSCLCs gain acquired resistance to these agents, representing one of the key challenges for modern precision oncology.

Performance analysis of SiRe next-generation sequencing panel in diagnostic setting: focus on NSCLC routine samples.

Aims: Following the development for liquid biopsies of the SiRe next-generation sequencing (NGS) panel that covers 568 clinical relevant mutations in and genes, in this current study, we apply this small NGS panel on tissue samples of lung cancer.

Methods: A total of 322 specimens were prospectively tested. Technical parameters were analysed on both cytological and histological samples.

Phase I/II study of gemcitabine and epirubicine in stage IIIB-IV non small cell lung cancer.

Platinum-based chemotherapy currently represents standard treatment for advanced non-small cell lung cancer (NSCLC). Gemcitabine is one of the most promising agents currently in use in advanced NSCLC. As a single-agent, epirubicin, showed tumour response rates ranging from 17% to 36% in NSCLC.

Supportive care in patients with advanced non-small-cell lung cancer.

The present study describes supportive care (SC) in patients with advanced non-small-cell lung cancer (NSCLC), evaluating whether it is affected by concomitant chemotherapy, patient's performance status (PS) and age. Data of patients enrolled in three randomised trials of first-line chemotherapy, conducted between 1996 and 2001, were pooled. The analysis was limited to the first three cycles of treatment.
