Effectiveness of Gefitinib against Non-Small-Cell Lung Cancer with the Uncommon EGFR Mutations G719X and L861Q.

In non-small-cell lung cancer, an exon 19 deletion and an L858R point mutation in the epidermal growth factor receptor (EGFR) are predictors of a response to EGFR-tyrosine kinase inhibitors. However, it is uncertain whether other uncommon EGFR mutations are associated with sensitivity to EGFR-tyrosine kinase inhibitors.

Molecular Basis of Drug Resistance: Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors and Anaplastic Lymphoma Kinase Inhibitors.

Over the past decade, several kinase inhibitors have been approved based on their clinical benefit in cancer patients. Unfortunately, in many cases, patients develop resistance to these agents via secondary mutations and alternative mechanisms. To date, several major mechanisms of acquired resistance, such as secondary mutation of the epidermal growth factor receptor (EGFR) gene, amplification of the MET gene and overexpression of hepatocyte growth factor, have been reported. This review describes the recen...

Omacetaxine mepesuccinate in the treatment of intractable chronic myeloid leukemia.

In a significant proportion of patients with chronic myeloid leukemia, resistance to BCR-ABL tyrosine kinase inhibitors develops due to acquisition of BCR-ABL kinase domain mutations and insensitivity of leukemia stem cells to tyrosine kinase inhibitors. Omacetaxine mepesuccinate (formerly called homoharringtonine) is a natural alkaloid that inhibits protein synthesis and induces cell death. Omacetaxine mepesuccinate has been recently approved by the US Food and Drug Administration to treat patients with ch...

Chemotherapy and EGFR tyrosine kinase inhibitors for treatment of brain metastases from non-small-cell lung cancer: survival analysis in 210 patients.

Chemotherapy and epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors are controversial in the treatment of patients with brain metastases from non-small-cell lung cancer (NSCLC).

Comparison of pemetrexed and docetaxel as salvage chemotherapy for the treatment for nonsmall-cell lung cancer after the failure of epidermal growth factor receptor-tyrosine kinase inhibitors.

To compare the therapeutic effects and adverse reactions of pemetrexed and docetaxel as salvage chemotherapy in patients with nonsmall-cell lung cancer (NSCLC) after the failure of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKI).

Sequential treatment of tyrosine kinase inhibitors and chemotherapy for EGFR-mutated non-small cell lung cancer: a meta-analysis of Phase III trials.

This aim of this study was to compare the efficacy of first-line tyrosine kinase inhibitor therapy followed, upon progression, by chemotherapy with the reverse sequence in patients with EGFR-mutated non-small cell lung cancer (NSCLC) in terms of overall survival.

Different treatment orders achieved similar clinical results: a retrospective study for retreatment of epidermal growth factor receptor tyrosine kinase inhibitors in 120 patients with non-small-cell lung cancer.

It was reported the retreatment of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) may bring benefit to non-small-cell lung cancer (NSCLC) patients who benefited previously. Nevertheless, the treatment order in most of the prior literature was gefitinib (G) to erlotinib (E), and little was known about whether other treatment order may also bring benefit to the patients.

Translational evidence on the role of Src kinase and activated Src kinase in invasive breast cancer.

Src kinase is a member of a non-receptor tyrosine kinase family. It has been implicated as a regulator of cell proliferation and survival and plays a complex role in cell adhesion and motility. In vitro evidence for a role for Src in breast cancer is compelling. However, only a few translational clinical studies have been undertaken in this field. This review summarises translational evidence on expression and activation of Src kinase in breast cancer patient cohorts exploring clinical significance and the...

Development of anaplastic lymphoma kinase (ALK) inhibitors and molecular diagnosis in ALK rearrangement-positive lung cancer.

The fusion of echinoderm microtubule-associated protein-like 4 with anaplastic lymphoma kinase (ALK) was identified as a transforming gene for lung cancer in 2007. This genetic rearrangement accounts for 2%-5% of non-small-cell lung cancer (NSCLC) cases, occurring predominantly in younger individuals with adenocarcinoma who are never- or light smokers. A small-molecule tyrosine-kinase inhibitor of ALK, crizotinib, was rapidly approved by the US Food and Drug Administration on the basis of its pronounced cli...

Reduced annexin A6 expression promotes the degradation of activated epidermal growth factor receptor and sensitizes invasive breast cancer cells to EGFR-targeted tyrosine kinase inhibitors.

The expression of annexin A6 (AnxA6) in AnxA6-deficient non-invasive tumor cells has been shown to terminate epidermal growth factor receptor (EGFR) activation and downstream signaling. However, as a scaffolding protein, AnxA6 may stabilize activated cell-surface receptors to promote cellular processes such as tumor cell motility and invasiveness. In this study, we investigated the contribution of AnxA6 in the activity of EGFR in invasive breast cancer cells and examined whether the expression status of Anx...

Ability of the Met Kinase Inhibitor Crizotinib and New Generation EGFR Inhibitors to Overcome Resistance to EGFR Inhibitors.

Although EGF receptor tyrosine kinase inhibitors (EGFR-TKI) have shown dramatic effects against EGFR mutant lung cancer, patients ultimately develop resistance by multiple mechanisms. We therefore assessed the ability of combined treatment with the Met inhibitor crizotinib and new generation EGFR-TKIs to overcome resistance to first-generation EGFR-TKIs.

Clinical Targeting of Mutated and Wild-type Protein Tyrosine Kinases in Cancer.

Clinical therapies for cancer have evolved from toxic, non-targeted agents to manageable, highly targeted therapies. Protein tyrosine kinases are a family of signaling molecules implicated in nearly every cancer type and are the foundation for the development of modern targeted agents. Recent genomic analyses have identified activating mutations, translocations, and amplifications of tyrosine kinases. Selective targeting of these genetically altered tyrosine kinases has resulted in significant clinical adva...

Aurora kinase inhibition induces PUMA via NF-kB to kill colon cancer cells.

Aurora kinases play a key role in mitosis and are frequently overexpressed in a variety of tumor cells. Inhibition of aurora kinases results in mitotic arrest and death of cancer cells, and has been explored as an anticancer strategy. However, how aurora inhibition kills cancer cells is poorly understood. In this study, we found that inhibition of aurora kinases by siRNA or small-molecule inhibitors led to induction of PUMA, a BH3-only Bcl-2 family protein, in colorectal cancer cells irrespective of p53 sta...

The Bim deletion polymorphism clinical profile and its relation with tyrosine kinase inhibitor resistance in Chinese patients with non-small cell lung cancer.

Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are widely used for the treatment of patients with advanced non-small cell lung cancer (NSCLC) who have EGFR mutations. Recent studies have indicated that some patients with positive mutations were refractory to EGFR TKIs if they harbored a B-cell chronic lymphocytic leukemia/lymphoma (Bcl-2)-like 11 (Bim) deletion polymorphism. The objective of the current work was to retrospectively study the Bim deletion polymorphism in Chinese pat...

Inhibition of OATP1B1 by tyrosine kinase inhibitors: in vitro-in vivo correlations.

Background:Several tyrosine kinase inhibitors (TKIs) can decrease docetaxel clearance in patients by an unknown mechanism. We hypothesised that these interactions are mediated by the hepatic uptake transporter OATP1B1.Methods:The influence of 16 approved TKIs on transport was studied in vitro using HEK293 cells expressing OATP1B1 or its mouse equivalent Oatp1b2. Pharmacokinetic studies were performed with Oatp1b2-knockout and OATP1B1-transgenic mice.Results:All docetaxel-interacting TKIs, including sorafeni...

Drug resistance and BCR-ABL kinase domain mutations in philadelphia chromosome-positive acute lymphoblastic leukemia from the imatinib to the second-generation tyrosine kinase inhibitor era: The main changes are in the type of mutations, but not in the frequency of mutation involvement.

Patients with Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) frequently relapse on imatinib with acquisition of BCR-ABL kinase domain (KD) mutations. To analyze the changes that second-generation tyrosine kinase inhibitors (TKIs) have brought in mutation frequency and type, a database review was undertaken of the results of all the BCR-ABL KD mutation analyses performed in the authors' laboratory from January 2004 to January 2013.

Mechanisms of acquired resistance to EGFR-tyrosine kinase inhibitor in Korean patients with lung cancer.

Despite an initial good response to epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI), resistance to treatment eventually develops. Although several resistance mechanisms have been discovered, little data exist regarding Asian patient populations.

Synergistic cell growth inhibition by the combination of amrubicin and Akt-suppressing agents in K-ras mutation-harboring lung adenocarcinoma cells: Implication of EGFR tyrosine kinase inhibitors.

Previously we showed that Akt-suppressing agents, combined with amrubicin, synergistically inhibited the growth of small cell lung cancer cells. The combined effects of chemotherapeutic agents and Akt-suppressing agents, including epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors, were evaluated in A549 lung adenocarcinoma cells harboring K-ras mutation and wild-type EGFR. Only amrubicin and not other chemotherapeutics (cisplatin, pemetrexed and paclitaxel) synergistically inhibited cell gr...

Impact of tyrosine kinase inhibitors on minimal residual disease and outcome in childhood Philadelphia chromosome-positive acute lymphoblastic leukemia.

Breakpoint cluster region-Abelson murine leukemia viral oncogene homolog 1 (BCR-ABL1) tyrosine kinase inhibitors (TKIs) improve the outcome of patients with childhood Philadelphia chromosome (Ph)-positive acute lymphoblastic leukemia (ALL) when they are incorporated into postremission induction chemotherapy. To date, no data are available on the impact of TKIs on minimal residual disease (MRD) at the end of induction therapy among patients who have a poor early response to 2 weeks of induction therapy that...

Is imatinib still the best choice as first-line oral TKI.

Targeted therapy is the buzz word these days. A decade back the emergence of tyrosine kinase inhibitor Imatinib on the horizon, as the targeted therapy, had captured the imagination of everyone in the field of cancer. It is encouraging to see a large number of patients getting relief from deadly CML disease and leading a good quality of life with the help of this drug. However, sky is not the limit and now we have second and third generation tyrosine kinase inhibitors. I still remember the sagacious smile o...

Distinct Clinical Outcomes of Non-Small Cell Lung Cancer Patients with Epidermal Growth Factor Receptor (EGFR) Mutations Treated with EGFR Tyrosine Kinase Inhibitors: Non-Responders versus Responders.

Treatment with epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) has been associated with favorable progression free survival (PFS) in patients with non-small cell lung cancers (NSCLC) harboring EGFR mutations. However, a subset of this population doesn't respond to EGFR-TKI treatment. Therefore, the present study aimed to elucidate survival outcome in NSCLC EGFR-mutant patients who were treated with EGFR TKIs.

Importance of adherence to BCR-ABL tyrosine-kinase inhibitors in the treatment of chronic myeloid leukemia.

Treatment of chronic myeloid leukemia with BCR-ABL tyrosine kinase inhibitors requires full adherence in order to maximize the likelihood of achieving optimal responses, and to minimize healthcare costs. In this article, we review some of the methods available for assessing compliance, the main consequences of nonadherence on treatment outcomes, major factors commonly associated with poor compliance, a few successful measures for improving adherence and the most accepted recommendations for proactively mana...

FLT3 Inhibitors in AML: Are We There Yet?

FMS-like tyrosine kinase 3 (FLT3) is the most frequently mutated gene in AML. Thirty percent of patients with acute myeloid leukemia (AML) harbor activating mutations in FLT3, either internal tandem duplication mutations in the juxtamembrane domain (FLT3-ITD) or point mutations in the tyrosine kinase domain (FLT3 TKD). Small molecule FLT3 inhibitors have emerged as an attractive therapeutic option in patients with FLT3 mutations; however, the clinical activity of early inhibitors was limited by a lack of se...

Factors associated with early progression of non-small-cell lung cancer treated by epidermal growth factor receptor tyrosine-kinase inhibitors.

Epidermal growth factor receptor tyrosine-kinase inhibitors (EGFR-TKI) are a therapeutic option as second-line therapy in non-small-cell lung carcinoma (NSCLC), regardless of the EGFR gene status. Identifying patients with early progression during EGFR-TKI treatment will help clinicians to choose the best regimen, TKI or chemotherapy. From a prospective database, all patients treated with gefitinib or erlotinib between 2001 and 2010 were retrospectively reviewed. Patients were classified into two groups acc...

Emerging protein kinase inhibitors for non-small cell lung cancer.

Introduction: In the current paradigm of precision medicine in non-small cell lung cancer (NSCLC), the therapeutic strategy is determined by the molecular characteristics. The best examples of this approach are the kinase inhibitors that selectively target tumors bearing an epidermal growth factor receptor (EGFR) mutation or an anaplastic lymphoma kinase (ALK) rearrangement. Emerging protein kinase inhibitors may enhance our ability to effectively treat these and other genomic subtypes of NSCLC. Areas cover...
