Isoflavone Extracts Enhance the Effect of Epidermal Growth Factor Receptor Inhibitors in NSCLC Cell Lines.

Aim: We investigated the effects of the pharmacological inhibition in vitro of epidermal growth factor receptor (EGFR) in combination with isoflavones.

Materials And Methods: Four anticancer drugs (erlotinib, gefitinib, afatinib and AZD9291) were combined with soy and red clover isoflavone extracts and used in cellular proliferation assays. The antitumor activity of inhibitors alone and in combination with isoflavone extracts was compared on three non-small cell lung cancer (NSCLC) cell lines with affiant EGFR genotype: A549 (EGFR wt); H1795 (EGFR T790M); HCC827 (EGFR del E746-A750).

Treating advanced non-small cell lung cancer in the elderly.

More than 40% of cases of all lung cancers are diagnosed in patients over the age of 70 years. Elderly patients have more comorbidities and tend to be less tolerant to toxic medical treatments than their younger counterparts. Thus, clinical data obtained in a younger population cannot be automatically extrapolated to the great majority of nonselected elderly patients with non-small cell lung cancer (NSCLC).

Non-small-cell lung carcinoma vaccines in clinical trials.

Non-small-cell lung cancer (NSCLC) is not considered to be immunogenic, but it may provide an accessible target for the properly primed immune system. Identifying lung tumor antigens and presenting them in the optimal context may enable the immune system to generate anti-lung tumor effector cells, which are usually absent. Despite encouraging preclinical and Phase I-II data, no specific active cancer vaccine has been approved for NSCLC therapy to date.

Combination of radiotherapy and targeted therapies in the treatment of locally advanced non-small cell lung cancer.

Lung cancer is the most common cancer in the world. One third of patients with non-small cell lung cancer (NSCLC) are diagnosed with locally or regionally advanced unresectable disease at presentation. Currently, in this stage of disease, a combination of chemotherapy and radiotherapy is the standard treatment approach for patients with good performance status, and concomitant chemo-radiotherapy has demonstrated to be the best therapeutic approach.

The role of maintenance treatment in advanced non-small-cell lung cancer: reality or early second line?

First-line platinum-based chemotherapy has reached a plateau of effectiveness for the treatment of patients with advanced non-small-cell lung cancer (NSCLC). In patients who reported a stable disease, no more than 4 cycles of chemotherapy are recommended while a maximum of 6 cycles is recommended in patients who are responding to therapy. A potential strategy with the aim of improving outcomes for NSCLC patients is to administer more therapy.

Factors driving the choice of the best second-line treatment of advanced NSCLC.

Platinum-based chemotherapy, with or without the antiangiogenetic drug bevacizumab, is the standard first-line therapy for patients with advanced non-small-cell lung cancer (NSCLC). The epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) gefitinib has been recently approved as treatment of patients with EGFR mutated tumors (including first-line). Three agents are approved for treating non-selected patients who progress after one prior regimen: docetaxel, pemetrexed, and the EGFR-TKI erlotinib.

Erlotinib in the treatment of non-small cell lung cancer: current status and future developments.

Erlotinib is an orally small molecule inhibiting the tyrosine kinase activity of the epidermal growth factor receptor (EGFR). Currently, erlotinib, at a standard oral daily dose of 150 mg, is licensed for the treatment of unselected recurrent non-small cell lung cancer (NSCLC) patients, however, it is being investigated in all stages of NSCLC. Erlotinib is well tolerated, with common toxicities including rash and diarrhoea.

Vascular endothelial growth factor receptor as target for advanced non-small cell lung cancer therapy.

Lung cancer remains the leading cause of malignancy-related mortality world-wide, in both men and women, with over a million cases diagnosed yearly. Non-small cell lung cancer (NSCLC) accounts for more than 80% of all lung cancers, and most patients are diagnosed with advanced disease. Although substantial progress has been made in the therapeutic options currently available for patients with advanced NSCLC, chemotherapy has apparently reached a plateau of effectiveness in improving survival in this subgroup of patients.
