Abstract
Lung cancer cells harbor various gene mutations in the mRNA sequence of the Epidermal Growth Factor Receptor (EGFR), especially the mutations of exon19del E746-A750, T790M, and L858R. This results in cancer progression and resistance to anticancer drugs (tyrosine kinase inhibitor; TKI). Therefore, the imaging analysis of EGFR mutations is required for the treatment planning for non-small cell lung cancers. This study focused on the imaging analysis of a single nucleotide substitute in EGFR mutated cancer cells. We developed three novel peptide nucleic acid (PNA)-DNA probes for recognizing and detecting the following three gene mutations in EGFR gene mutations. The PNA-DNA probes consist of fluorescein isothiocyanate (FITC) conjugated PNA as a detection probe and Dabcyl conjugated DNA as a quencher probe. The PNA-DNA probes were used to validate the feasibility for detecting three EGFR mutated sequences: exon19del E746-A750, T790M, and L858R. The three probes emitted fluorescent dose-dependent signals against three target DNA and RNA. Using the three PNA-DNA probes, we succeeded in distinguishing three kinds of lung-cancer cell lines (H1975, PC-9, and A549) which have different EGFR mutations by the fluorescence in situ hybridization (FISH) method.

Abstract
CONTEXT The advent of genotype-based therapy and predictive biomarkers for lung cancer has thrust the pathologist into the front lines of precision medicine for this deadly disease. OBJECTIVE To provide the clinical background, current status, and future perspectives of molecular targeted therapy for lung cancer patients, including the pivotal participation of the pathologist. DATA SOURCES Data were obtained from review of the pertinent peer-reviewed literature. CONCLUSIONS First-generation tyrosine kinase inhibitors have produced clinical response in a limited number of non-small cell lung cancers demonstrated to have activating mutations of epidermal growth factor receptor or anaplastic lymphoma kinase rearrangements with fusion partners. Patients treated with first-generation tyrosine kinase inhibitors develop acquired resistance to their therapy. Ongoing investigations of second-generation tyrosine kinase inhibitors and new druggable targets as well as the development of next-generation genotyping and new antibodies for immunohistochemistry promise to significantly expand the pathologist's already crucial role in precision medicine of lung cancer.

Abstract
Skin disorders are among the most common adverse events related to treatment with epidermal growth factor receptor (EGFR) kinase inhibitors, and of these, erlotinib is known to cause more frequent and severe skin disease than other agents in this class. Although previous reports have shown that cutaneous manifestations are triggered by the inhibition of multiple EGFR-related homeostatic functions of the skin, this mechanism alone cannot explain the differences in frequency and severity of skin disorders caused by different kinase inhibitors. In this study, we focused on the relationship between the off-target kinase inhibition and aggravation of skin disorders. Based on calculations using reported K(d) values and plasma drug concentrations, serine/threonine kinase 10 (STK10) and Ste20-like kinase (SLK) were selected as candidates preferentially inhibited by erlotinib over gefitinib. In vitro experiments confirmed that STK10 and SLK kinase activity are inhibited by erlotinib at clinical concentrations, whereas only STK10 is slightly inhibited by gefitinib. It was also shown that erlotinib up-regulated lymphocytic responses such as interleukin (IL)-2 secretion and cell migration at clinical concentrations, whereas gefitinib did not affect lymphocyte activity. Moreover, small interfering RNA experiments revealed that STK10 plays a major role in up-regulation of the lymphocytic responses induced by erlotinib treatment. Finally, the role of erlotinib-induced lymphocyte activation was assessed in vivo using irritant hypersensitivity models. The results indicated that erlotinib aggravates cutaneous inflammatory reactions through the activation of lymphocytic responses such as IL-2 secretion and cell migration. These results demonstrated that off-target inhibition of STK10 by erlotinib enhances lymphocytic responses, which lead to the aggravation of skin inflammation.

Abstract
Gefitinib (Iressa; AstraZeneca Pharmaceuticals, Wilmington, DE) is an oral epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) with favorable toxicity and antitumor activity in pretreated patients with non-small cell lung cancer (NSCLC). The purpose of this study was to evaluate the toxicity and efficacy of gefitinib in patients with advanced NSCLC treated at our institution as part of an expanded access protocol; 112 patients with advanced NSCLC were entered. All patients had failed at least one previous chemotherapy regimen, or were not suitable for any systemic chemotherapy because of poor performance status (PS), or were ineligible for other clinical trials. Therapy consisted of gefitinib 250 mg orally once daily; 10.5% (95% CI 5.3-17.9%) of patients achieved partial/minimal response (PR/MR) and 29.5% (95% CI 21.0-39.2%) had stable disease (SD), resulting in a disease control rate (PR/MR+SD) of 40% (95% CI 31-50%). The median duration of treatment for all patients was 12 weeks (range 2-116 weeks) and for patients achieving disease control 28 weeks (range 8-116). Nine patients received gefitinib for more than 1 year. Median survival was 30 weeks. Symptoms were improved in 36% of evaluable patients, and 64% of patients who achieved disease control experienced improvement of their disease related symptoms. Adverse events were generally mild and consisted mostly of skin rash (48%) and diarrhea (38%). A statistically significant association was observed between disease control and skin rash (p = < 0.001), nonsmoking status (p = 0.048), and symptom improvement (p = 0.001). The disease control rate was not statistically associated with histology, PS, gender, or number of prior treatments. In addition, longer survival was significantly associated with skin rash (p = < 0.001) and symptom improvement (p = < 0.001). Gefitinib demonstrated relevant clinical activity and a favorable toxicity profile in pretreated patients with advanced NSCLC. The development of toxicity was associated with a favorable response. In addition, a history of never having smoked seems to predict a higher efficacy of gefitinib.

Abstract
The epidermal growth factor receptor (EGFR) is a cellular transmembrane receptor with tyrosine kinase enzymatic activity which plays a key role in human cancer. EGFR-dependent signaling is involved in cancer cell proliferation, apoptosis, angiogenesis, invasion and metastasis. Targeting the EGFR is a valuable molecular approach in cancer therapy. Several anti-EGFR drugs are in Phase III clinical development as single agent or in combination with other anticancer modalities. Cetuximab (Erbitux), a chimeric human-mouse monoclonal immunoglobin (Ig)G1 antibody, which blocks ligand binding and functional activation of the EGFR, is currently registered in the USA, Switzerland and the European Union for the treatment of advanced, irinotecan-refractory colorectal cancer. Gefitinib, (Iressa), a small molecule EGFR-selective inhibitor of tyrosine kinase activity which blocks EGF autophosphorylation and activation, has been the first EGFR-targeting drug to be registered in 28 countries worldwide, including the USA, for the third-line treatment of chemoresistant non-small cell lung cancer patients. This review will focus on the preclinical background and on the clinical data with the anti-EGFR drugs in most advanced clinical development. Furthermore, a series of open clinical issues for the development of optimal strategies of using EGFR-targeting agents will be discussed.

Abstract
Although pulmonary toxicity associated with gefitinib, an epidermal growth factor receptor inhibitor, has been reported recently, the accumulation of clinical information and the underlying mechanisms of gefitinib-induced interstitial lung disease (ILD) remain insufficient and unclear. After retrospectively reviewing the clinical records and chest X-rays of 489 lung cancer patients who were treated with gefitinib, we diagnosed four cases of gefitinib-induced ILD who underwent fiberoptic bronchoscopy and bronchoalveolar lavage (BAL). We found that the period of time from starting gefitinib to the onset of ILD was short, and concluded that a careful and close observation of a chest imaging study and a collection of respiratory symptoms was recommended. All four patients were treated with a high dose of corticosteroids, and ILD was resolved. We detected high levels of interferon-inducible protein-10 in BAL fluid, although we could not demonstrate the characteristic features of laboratory findings or BAL fluid cell analysis. We speculated that a Th1 type of lung tissue inflammation or lung injury might be involved as a part of mechanisms underlying gefitinib-induced ILD.

Abstract
Gefitinib (ZD1839) is the most widely studied targeting agent in the area of non-small-cell lung cancer (NSCLC). Gefitinib is an orally active epidermal growth factor receptor (EGFR) tyrosine kinase (TK) inhibitor. In order to assess the role of gefitinib in the management of NSCLC patients, we systematically reviewed published clinical trials from a daily practice perspective. A systematic research was made in the international medical literature. Gefitinib demonstrated a good tolerance and an encouraging efficacy in pretreated NSCLC patients in preclinical studies. These results were then confirmed in two phase II trials (IDEAL 1 and 2) involving more than 400 patients mostly pretreated with a platinum-containing regimen and docetaxel. All these results were reinforced by those of retrospective studies on patients enrolled in a compassionate use programme. Thus, two phase III trials in chemo-naive patients were initiated (INTACT 1 and 2). Unfortunately, the use of gefitinib with standard combination chemotherapy provided no survival benefit nor response rate or progression-free survival improvement over placebo. Furthermore, we also reviewed the results of studies interested in the characterization of predictive clinical or biological markers for response to gefitinib and discussed the results obtained with other EGFR inhibitors. The efficacy of gefitinib in the first-line setting of each stage of NSCLC has to be further studied through clinical trials. Furthermore, translational studies characterizing the molecular features involved in the response to anti-EGFR-targeted therapies are needed.

Abstract
Skin rash associated with HER1/epidermal growth factor receptor (EGFR) inhibitors is common. The lack of clinical and patient guidance for this often chronic and sometimes distressing side effect makes rash management and etiology investigation high priorities. To address this, oncologists and dermatologists with experience with HER1/EGFR inhibitors attended the HER1/EGFR Inhibitor Rash Management Forum. Recommendations include continued analysis of the correlation between rash and clinical outcome and improving the accuracy and reproducibility of terminology and grading systems. Because acne vulgaris has a unique pathology, and the pathology and etiology of rash are unclear yet distinct from acne vulgaris, using such terms as acne, acne-like, or acneiform should be avoided. Until there is a specific dermatological definition, rash is best described using phenotypic terms for its appearance and location. It is currently unknown which agents are best for treating rash. Clinical trials of rash treatments are urgently required, and suggestions for agents to consider are made based on current knowledge. The effect of dose reduction or interruption on rash should also be investigated. Secondarily infected rash may be more frequent than has been previously recognized, and some investigators favor empiric use of an oral antibiotic if this appears to be the case. Suggestions for patients include makeup to camouflage the rash and an emollient to prevent and alleviate skin dryness. The increasing use of HER1/EGFR-targeted agents makes managing rash important. We hope the outcomes from this Forum provide background for future studies.

Abstract
Institutional series suggest specific subgroups of patients with non-small cell lung cancer (NSCLC); female, Asian, non-smokers, respond preferentially to gefitinib. Vancouver, BC, has a large Asian population and therefore is an ideal location to study this differential effect in a Western setting. We performed a retrospective analysis of patients treated with single agent gefitinib to determine if our experience reflects this observation. The pathology, radiology, laboratory investigations and clinical records of 61 patients treated with gefitinib at the BCCA between April 2002 and May 2004 were reviewed. Partial radiologic response was defined as per SWOG response criteria. Symptom responses were subjectively evaluated from chart review. Baseline characteristics at diagnosis; 62% Caucasian, 38% Asian, male 47%, smokers 67%, non-smokers 33%, ECOG 0/1 59%; tumor histology: 57% adenocarcinoma, 13% bronchoalveolar variant, 7% squamous, 23% other. Median treatment duration was 2 months. On radiologic review, 14 patients had a partial response, 25 had stable disease, 21 progressed, and 1 unknown. Twenty patients reported improved symptoms after>/=1 month, 23 had no change, 17 had symptom progression and 1 unknown. Toxicity was minimal; one patient had grade 3 hepatotoxicity that resolved with treatment cessation. Of the 14 radiological responders, 10 were Asian, 10 ECOG 0/1, 10 female, 8 non-smokers, 8 adenocarcinoma and 4 bronchoalveolar variant. At the BCCA, in a select number of patients with advanced NSCLC, gefitinib demonstrated radiologic evidence of anti-tumor activity and provided clinical benefit with minimal side effects. Most of the responders were patients of Asian ethnicity who had immigrated to Canada from China, Taiwan or Hong Kong. Our results suggest that the preferential response to gefitinib seen in the Asian population is preserved in a Western setting. The molecular basis of the improved response rate observed in the subset of female, Asian, non-smokers with adenocarcinoma or bronchoalveolar variant is currently being explored by gene sequencing studies at the British Columbia Cancer Agency Genome Science Centre.

Abstract
The epidermal growth factor receptor (EGFR) is a cell membrane receptor that plays a key role in cancer development and progression. Ligand-activated EGFR-dependent signalling is involved in cell proliferation, apoptosis, angiogenesis and metastatic spread. Targeting the EGFR, therefore, represents a promising molecular approach in cancer treatment. Several anti-EGFR agents are in clinical development. Three drugs are currently in Phase II and III development as single agents, or in combination with other anticancer modalities: IMC-225 (cetuximab/Erbitux; ImClone), a chimaeric human-mouse monoclonal IgG(1) antibody, which blocks ligand binding and functional activation of the EGFR; OSI-774 (erlotinib/Tarceva; Genentech/OSI/Roch) and ZD1839 (gefitinib/Iressa; AstraZeneca), two small molecule EGFR-selective inhibitors of tyrosine kinase enzymatic activity, which prevent EGFR autophosphorylation and activation. Iressa is the first EGFR-targeting agent to be registered as an anticancer drug in Japan, in Australia and in the US for the third-line treatment of chemoresistant non-small cell lung cancer (NSCLC) patients. This review will focus on the preclinical background and on the results from the first series of clinical trials with these drugs. Furthermore, continuing clinical trials and a series of open clinical issues for the development of optimal strategies of using EGFR-targeting agents will be discussed.

Abstract
Gefitinib, a selective epidermal growth factor receptor tyrosine kinase inhibitor, is an effective treatment for patients with non-small cell lung cancer (NSCLC). Some investigators have recently reported several patients complicated by acute lung injury after the initiation of gefitinib administration. In this report, we investigated the efficacy and adverse events during treatment with gefitinib. The subjects of this study were all of the 110 patients with NSCLC who were treated in our hospital and its eight branch hospitals. Patients received gefitinib at a dose of 250 mg once daily. The response rate was 30%. The frequently reported adverse events were skin disorders, gastrointestinal disturbances, liver dysfunction and acute lung injury. Five of the 12 patients who were considered to have suffered acute lung injury died of progressive respiratory failure. Of the nine patients who had pulmonary fibrosis before use of gefitinib, five developed acute lung injury during the treatment. Sera from three of the 12 patients were evaluated and all three showed increases of surfactant protein (SP)-A, SP-D and KL-6. We conclude that gefitinib was clinically useful. However, several patients suffered acute lung injury which could have been caused by gefitinib. A detection system including SP-A, SP-D and KL-6 as prime candidates as markers should be established as promptly as possible. Clinicians should be aware that treatment of NSCLC with gefitinib involves the risk of acute lung injury and therefore careful consideration should be given before deciding whether or not gefitinib is indicated for treatment. Further study is necessary to elucidate the mechanism of acute lung injury by gefitinib.

Abstract
INTRODUCTION Gefitinib (Iressa, ZD 1839; AstraZeneca) is a selective Epidermal Growth Factor receptor tyrosine kinase inhibitor. In two randomized phase II trials (IDEAL 1 and IDEAL 2), it has demonstrated an activity against NSCLC, showing partial response and symptoms improvement rates respectively in about 20% and 40% of patients. Multivariate analyses revealed that being a woman, a non-smoker and having an adenocarcinoma was associated with response rate. METHODS We describe a retrospective study of patients receiving Gefitinib as a third line compassionate treatment of NSCLC. RESULTS We enrolled 37 patients (29 men, 8 women). Tumors included 25 adenocarcinoma, 4 squamous cell carcinoma, 7 large cell carcinoma, and 1 neuroendocrine carcinoma. Partial response rate was 8.1%, and stable disease rate 27.0%. The 3 responders were all non-smoker women, with an histological type of adenocarcinoma. Symptoms improvement was observed in 59.5% of patients. Main toxicities were diarrhoea and skin reactions. We observed that responding patients had more adverse drugs-related reactions than stable or non-responding patients. CONCLUSIONS Gefitinib is a meaningful active therapy in NSCLC with a favorable toxicity profile. We suggest that being a woman, a never-smoker and having an adenocarcinoma may be clinical predictive factors of response to Gefitinib.

Abstract
The therapy of non-small cell lung cancer (NSCLC) has reached a plateau in improving patient survival, with overall disappointing results. Thus, clinical research for new treatment strategies is warranted. Advances in the singling out molecular targets for NSCLC treatment has granted the development of several new biological agents. In the present paper we describe the main clinical data currently available on targeted agents in the treatment of NSCLC, focusing on epidermal growth factor receptor family inhibitors, angiogenesis inhibitors, signal transduction inhibitors, eicosanoid pathway inhibitors, vaccines and gene therapy. Several targeted agents have been introduced into clinical trials in NSCLC, mainly in advanced disease, with the first phase III study results being recently made available. To date, few of these new agents can offer hope of a substantial impact on the natural history of NSCLC, and negative results are more commonly reported than positive ones. Nevertheless, clinically-meaningful advances have already been achieved in chemotherapy refractory advanced NSCLC patients, with gefitinib, an epidermal growth factor receptor tyrosine kinase inhibitor, representing a further chance of tumor control and symptom palliation. Moreover, important lessons can be learned from this first generation of clinical trials.

Abstract
PURPOSE OF REVIEW The epidermal growth factor receptor is a cell membrane receptor that plays a key role in cancer development and progression. Ligand-activated epidermal growth factor receptor-dependent signaling is involved in cell proliferation, apoptosis, angiogenesis, invasion, and metastasis. Targeting the epidermal growth factor receptor represents a promising molecular approach in cancer treatment. Several antiepidermal growth factor receptor agents are in clinical development. This review focuses on the available clinical data on epidermal growth factor receptor-targeting drugs in the treatment of nonsmall cell lung cancer. RECENT FINDINGS Three drugs are currently in phase 2 and phase 3 development as single agents or in combination with other anticancer therapies in nonsmall cell lung cancer patients: cetuximab (Erbitux), a chimeric human-mouse monoclonal IgG1 antibody that blocks ligand binding and functional epidermal growth factor receptor activation; and erlotinib (Tarceva) and gefitinib (Iressa), two orally bioavailable, small-molecule epidermal growth factor receptor inhibitors of tyrosine kinase enzymatic activity that prevent epidermal growth factor receptor autophosphorylation and activation. Single-agent gefitinib treatment has determined a 10 to 20% response rate and a 30 to 50% symptom improvement in previously treated, chemotherapy-refractory advanced nonsmall cell lung cancer patients. Gefitinib has been the first epidermal growth factor receptor-targeting agent to be registered as an anticancer drug in several countries, including Japan, Australia, and the United States, for the third-line treatment of chemoresistant nonsmall cell lung cancer patients. SUMMARY Antiepidermal growth factor receptor has shown promising antitumor activity in nonsmall cell lung cancer patients with a mild toxicity profile. However, a series of important clinical issues such as selection of potentially responsive patients and optimal combination with conventional anticancer treatments needs to be addressed to use these drugs better in lung cancer.

Abstract
The activity and toxicity profile of gefitinib in non-small cell lung cancer (NSCLC) patients aged 70 years or older has been only partially evaluated. The aim of this study was to evaluate the response rate and safety of gefitinib in elderly NSCLC patients. Elderly NSCLC patients pretreated with chemotherapy and with at least one measurable lesion received gefitinib at the daily dose of 250 mg until disease progression, unacceptable toxicity or refusal. From August 2001 to May 2003, 40 consecutive elderly patients have been enrolled onto the study in three Italian institutions. We observed one complete (2.5%) and one partial response (2.5%), 18 disease stabilisations (NC: 45%) lasting at least 2 months, including six patients (15%) who had disease stabilisation of 6 months or longer, for an overall disease control rate of 50% (95% CI: 34.5-65.5%). The median duration of response was 4.4 months (range 1.7-9.2). The side effects were generally mild and consisted of diarrhoea and skin toxicity. Grade 1-2 diarrhoea occurred in 23.6%, and one patient experienced grade 4 diarrhoea, requiring hospitalisation. Grade 1-2 skin toxicity, including rash, pruritus, dry skin, and acne, occurred in 20 patients (52.6%). Gefitinib is safe and well tolerated in elderly pretreated NSCLC patients. The disease-control rate achieved suggests that this drug could represent a valid option in the management of this unfavourable subgroup of patients.
