Abstract
Targeted anticancer drugs block cancer cell growth by interfering with specific signaling pathways vital to carcinogenesis and tumor growth rather than harming all rapidly dividing cells as in cytotoxic chemotherapy. The Response Evaluation Criteria in Solid Tumor (RECIST) system has been used to assess tumor response to therapy via changes in the size of target lesions as measured by calipers, conventional anatomically based imaging modalities such as computed tomography (CT), and magnetic resonance imaging (MRI), and other imaging methods. However, RECIST is sometimes inaccurate in assessing the efficacy of targeted therapy drugs because of the poor correlation between tumor size and treatment-induced tumor necrosis or shrinkage. This approach might also result in delayed identification of response when the therapy does confer a reduction in tumor size. Innovative molecular imaging techniques have rapidly gained importance in the dawning era of targeted therapy as they can visualize, characterize, and quantify biological processes at the cellular, subcellular, or even molecular level rather than at the anatomical level. This review summarizes different targeted cell signaling pathways, various molecular imaging techniques, and developed probes. Moreover, the application of molecular imaging for evaluating treatment response and related clinical outcome is also systematically outlined. In the future, more attention should be paid to promoting the clinical translation of molecular imaging in evaluating the sensitivity to targeted therapy with biocompatible probes. In particular, multimodal imaging technologies incorporating advanced artificial intelligence should be developed to comprehensively and accurately assess cancer-targeted therapy, in addition to RECIST-based methods.

Abstract
Non-small cell lung cancer (NSCLC) is one of the most common types of lung cancer worldwide. It metastasizes rapidly and has a poor prognosis. The first-line treatment for most patients is a combination of chemotherapy and radiation. In many subjects, using targeted treatments alongside chemoradiation has shown a better outcome in terms of progression and quality of life for patients. These targeted treatments include small biological inhibiting molecules and monoclonal antibodies. In this review, we have assessed studies focused upon the treatment of non-small cell lung cancer. Some therapies are approved, such as bevacizumab and atezolizumab, while some are still in clinical trials, such as ficlatuzumab and ipilimumab, and others have been rejected due to inadequate disease control, such as figitumumab.

Abstract
Bispecific (BsAb) and biparatopic (BpAb) antibodies emerged as promising formats for therapeutic biologics exhibiting tailor-made functional properties. Over recent years, chicken-derived antibodies have gained traction for diagnostic and therapeutic applications due to their broad epitope coverage and convenience of library generation. Here we report the first generation of a biparatopic common light chain (cLC) chicken-derived antibody by an epitope binning-based screening approach using yeast surface display. The resulting monospecific antibodies target conformational epitopes on domain II or III of the epidermal growth factor receptor (EGFR) with lower double- or single-digit nanomolar affinities, respectively. Furthermore, the domain III targeting variant was shown to interfere with epidermal growth factor (EGF) binding. Utilizing the Knob-into-Hole technology (KiH), a biparatopic antibody with subnanomolar affinity was generated that facilitates clustering of soluble and cell-bound EGFR and displayed enhanced antibody-dependent cell-mediated cytotoxicity (ADCC) compared to the parental antibodies. This strategy for generating cLC-based biparatopic antibodies from immunized chickens may pave the way for their further development in therapeutic settings.

Abstract
Although pruritus may sometimes be a consequential situation to neoplasms, it more frequently emerges after commencing chemotherapy. In this review, we present our analysis of the chemotherapy treatments that most often induce skin changes and itching. After discussing conventional chemotherapies capable of inducing pruritus, we present our evaluation of new drugs such as immunological checkpoint inhibitors (ICIs), tyrosine kinase inhibitors, and monoclonal antibodies. Although ICIs and targeted therapy are thought to damage tumor cells, these therapies can modify homeostatic events of the epidermis and dermis, causing the occurrence of cutaneous toxicities in treated subjects. In the face of greater efficacy, greater skin toxicity has been reported for most of these drugs. A remarkable aspect of some reports is the presence of a probable correlation between cutaneous toxicity and treatment effectiveness in tumor patients who were treated with novel drugs such as nivolumab or pembrolizumab. Findings from these experiments demonstrate that the occurrence of any grade of skin side effects can be considered as a predictor of a better outcome. In the near future, studies on the relationship between the onset of skin alterations and outcomes could open new perspectives on the treatment of neoplasms through specific target therapy.

Abstract
Autosomal dominant polycystic kidney disease (ADPKD) is a genetic disease characterized by an overexpression and mislocalization of epidermal growth factor receptor (EGFR) to the apical membranes of cystic epithelial cells. Nimotuzumab is a humanized antibody that recognizes an extracellular domain III of human EGFR. The aim of this study was to assess the pharmacokinetic behavior of nimotuzumab in patients with ADPKD given as a single dose. A phase I, single-center, and noncontrolled open clinical study was conducted. Five patients were enrolled at each of the following fixed-dose levels: 50, 100, 200, and 400 mg. Intravenous continuous infusions of nimotuzumab were administered every 14 days during a year, except the first administration, when blood samples were drawn during 28 days for pharmacokinetic assessments. Subjects were closely monitored during the trial and at completion of the administration of nimotuzumab, including the anti-idiotypic response. For the first time, nimotuzumab was used for treating a nononcological disease. The administration of nimotuzumab showed dose-dependent kinetics. Nimotuzumab does not develop anti-idiotypic response against the murine portion present in the hypervariable region of the antibody present in the serum of the patients treated. No significant differences were found in the systemic clearance between the 100- and 400-mg dose, which indicates that the optimal biological dose is in this range of dose.

Abstract
Lung cancer still represents one of the most common and fatal neoplasm, accounting for nearly 30% of all cancer-related deaths. Targeted therapies based on molecular tumor features and programmed death-1 (PD-1)/programmed death ligand-1 (PDL-1) blockade immunotherapy have offered new therapeutic options for patients with advanced non-small-cell lung cancer (NSCLC). Activation of the epidermal growth factor receptor (EGFR)-pathway promotes tumor growth and progression, including angiogenesis, invasion, metastasis and inhibition of apoptosis, providing a strong rationale for targeting this pathway. EGFR expression is detected in up to 85% of NSCLC and has been demonstrated to be associated with poor prognosis. Two approaches for blocking EGFR signaling are available: prevention of ligand binding to the extracellular domain with monoclonal antibodies (mAbs) and inhibition of the intracellular tyrosine kinase activity with small molecules. There is a strong rationale to consider the tumor's level of EGFR expression as one of the most significant predictive biomarkers in this setting. In this paper we provide an update focusing on the current status of EGFR-directed mAbs use for the treatment of patients with advanced NSCLC, through a review of all clinical trials involving anti-EGFR mAbs in combination with chemotherapy (CT) for advanced disease and with chemo-radiotherapy for stage III disease. Here we also discuss the current status of predictive biomarkers for anti-EGFR mAbs when added to first-line CT in patients with advanced NSCLC. Finally, we focused on the relevance of EGFR fluorescence in situ hybridization (FISH)+ and immunohistochemistry (IHC)-Score ≥ 200 as predictive biomarkers for the selection of patients who would be most likely to derive a clinical benefit from treatment with CT in combination with anti-EGFR mAbs, with particular reference also to histology.

Abstract
Abstract
Objectives
Monoclonal antibody-based of cancer therapy has been considered as one of the most successful therapeutic strategies for both haematologic malignancies and solid tumours in the last two decades. Epidermal growth factor receptor (EGFR) family signalling pathways play a key role in the regulation of cell proliferation, survival and differentiation. Hence, anti-EGFR family mAbs is one of the most promising approaches in cancer therapy.
Key findings
Here, recent advances in anti-EGFR mAb including approved or successfully tested in preclinical and clinical studies have been reviewed. Although we focus on monoclonal antibodies against the EGF receptor, but the mechanisms underlying the effects of EGFR-specific mAb in cancer therapy, to some extend the resistance to existing anti-EGFR therapies and some therapeutic strategies to overcome resistance such as combination of mAbs on different pathways are briefly discussed as well.
Summary
The EGFR family receptors, is considered as an attractive target for mAb development to inhibit their consecutive activities in tumour growth and resistance. However, due to resistance mechanisms, the combination therapies may become a good candidate for targeting EGFR family receptors.

Abstract
The therapeutic arsenal in solid tumors comprises different anticancer strategies with diverse chemotherapeutic agents and a growing number of biological substances. Large clinical study-based chemotherapeutic protocols combined with biologicals have become an important component in (neo-) adjuvant therapy alongside surgery in solid cancers as well as radiation therapy in some instances. In recent years, monoclonal antibodies have entered the mainstream of cancer therapy. Their first use was as antagonists of oncogenic receptor tyrosine kinases, but today monoclonal antibodies have emerged as long-sought vehicles for the targeted delivery of potent chemotherapeutic agents and as powerful tools to manipulate anticancer immune responses. There is a growing number of FDA approved monoclonal antibodies and small molecules targeting specific types of cancer suggestive of the clinical relevance of this approach.Targeted cancer therapies , also referred to as personalized medicine, are being studied for use alone, in combination with other targeted therapies, and in combination with chemotherapy. The use of monoclonal antibodies in colorectal and gastric cancer for example have shown best outcome when combined with chemotherapy, even though single agent anti-EGFR antibodies seem to be active in particular setting of metastatic colorectal cancer patients. However, it is not well defined whether the addition of anti-VEGF - and anti-EGFR strategies to chemotherapy could improve outcome in those patients susceptible to colorectal cancer-related metastases resection. Among the most promising approaches to activating therapeutic antitumor immunity is the blockade of immune checkpoints, exemplified by the recently FDA-approved agent, Ipilimumab, an antibody that blocks the coinhibitory receptor CTLA-4. Capitalizing on the success of Ipilimumab, agents that target a second coinhibitory receptor, PD-1, or its ligand, PD-L1, are in clinical development. This section attempts to discuss recent progress of targeted agents and in tackling a more general target applicable to gastrointestinal cancer .

Abstract
ErbB proteins overexpression, in both normal and mutated forms, is associated with invasive forms of cancer prone to metastasis and with stronger antiapoptotic mechanisms and therefore more challenging to treat. Downstream effectors of ErbB receptors mediating these phenotypic traits include MAPK, STAT, and PI3K/AKT/mTOR pathways. Various phytochemical compounds were studied for their large number of biological effects including anticancer activity. Among these compounds, epigallocatechin-3-gallate (EGCG), the main catechin from green tea leaves, and curcumin, component of the curry powder, constituted the object of numerous studies. Both compounds were shown to act directly either on ErbB expression, or on their downstream signaling molecules. In this paper we aim to review the involvement of ErbB proteins in cancer as well as the biologic activity of EGCG and curcumin in ErbB expressing and overexpressing malignancies. The problems arising in the administration of the two compounds due to their reduced bioavailability when orally administered, as well as the progress made in this field, from using novel formulations to improved dosing regimens or improved synthetic analogs, are also discussed.

Abstract
PURPOSE OF REVIEW The epidermal growth factor receptor (EGFR) is overexpressed in many nonsmall cell lung cancers (NSCLCs). Blockade of EGFR by monoclonal antibodies has been studied as a strategy to improve the outcome of first-line chemotherapy in patients with NSCLC. The present review updates the findings from phase III trials. RECENT FINDINGS Cetuximab improved survival when combined with first-line chemotherapy and this benefit was limited to patients with high EGFR expression in their tumors. A Southwest Oncology Group study currently prospectively evaluates the predictive biomarkers for cetuximab. In the SQUIRE phase III trial, necitumumab added to cisplatin and gemcitabine increased the survival in patients with advanced squamous cell NSCLC. The INSPIRE trial studied chemotherapy with and without necitumumab in patients with nonsquamous NSCLC but was prematurely halted because of increased thromboembolic events with chemotherapy and necitumumab. SUMMARY EGFR monoclonal antibodies improved the outcome including survival in selected patients with advanced NSCLC. Prospective validation of predictive biomarkers is ongoing.

Abstract
Cetuximab is a chimeric monoclonal antibody that is directed towards the epidermal growth factor receptor (EGFR). It has been evaluated in combination with first-line chemotherapy in several phase II and two phase III trials in patients with advanced NSCLC. The phase III FLEX trial demonstrated improved survival for cetuximab combined with cisplatin plus vinorelbine compared to chemotherapy alone. The BMS099 trial failed to show a significant improvement in progression-free survival but resulted in a hazard ratio for death similar to the one seen in the FLEX trial. A meta-analysis of four randomized trials confirmed the efficacy of cetuximab when added to chemotherapy. EGFR expression levels based on an immunohistochemistry score have recently been shown to predict benefit from cetuximab in the FLEX trial. In patients with high EGFR expression, patients had prolonged survival when treated with chemotherapy plus cetuximab compared to chemotherapy alone. In patients with low EGFR expression, outcome was not different between the two treatment arms. Thus platinum-based chemotherapy combined with cetuximab represents a new treatment option for patients with advanced NSCLC and high EGFR expression in their tumors. Cetuximab is also evaluated in combination with chemoradiotherapy in patients with stage III NSCLC.

Abstract
Cetuximab improved survival when added to first-line platinum-based chemotherapy in patients with advanced non-small cell lung cancer. In order to determine those patients who will derive the greatest benefit from the addition of cetuximab, the associations of clinical and tumor features with clinical outcome were determined. High EGFR expression of tumor cells based on an immunohistochemistry score was shown to predict benefit of cetuximab. Among patients with high EGFR expression, the hazard ratio for death was 0.73 in favor of chemotherapy plus cetuximab compared to chemotherapy alone. Among patients with low EGFR expression, no difference in survival was observed between patients treated with chemotherapy plus cetuximab compared to those treated with chemotherapy alone. The treatment interaction test was significant. KRAS mutation status and EGFR copy numbers were without predictive value. Patients with EGFR-activating mutations in their tumors had longer survival independent of the use of cetuximab. In conclusion, EGFR expression levels lend themselves as predictive biomarkers for the selection of those patients who will benefit from the addition of cetuximab to first-line chemotherapy with platinum-based doublets.

Abstract
In recent years, targeted agents have rapidly evolved as effective tools in the clinical management of a broad range of malignant diseases. These agents disrupt molecular mechanisms and signaling modules that drive the malignant phenotype in defined subsets of malignancies. Beyond the intended cellular targets crucial to tumor growth and progression, these agents also affect signal transduction in normal cells and tissues. The resulting adverse events and their clinical management continue to change, as newer agents with an ever-increasing target spectrum are developed. We provide a succinct overview of dermatologic toxicities arising from the targeting of receptor tyrosine kinases and downstream effectors. Emergent insights into the pathomechanisms involved and the use of this knowledge base to alleviate cutaneous adverse events are discussed.

Abstract
Several monoclonal antibodies directed against the epidermal growth factor receptor (EGFR) have been evaluated in patients with non-small cell lung cancer (NSCLC). Cetuximab, a chimeric monoclonal antibody, has been studied in combination with first-line chemotherapy in phase II and two phase III trials in patients with advanced NSCLC. The phase III FLEX trial demonstrated an increase in survival for cisplatin/vinorelbine plus cetuximab compared to chemotherapy alone in patients with advanced EGFR-expressing NSCLC. Cetuximab added to carboplatin/paclitaxel failed to improve progression-free survival in the BMS099 phase III trial. However, a meta-analysis of four randomized trials confirmed a significant survival benefit for platinum-based chemotherapy plus cetuximab compared to chemotherapy alone. High EGFR expression of tumor cells was then shown to predict the benefit of cetuximab, whereas KRAS mutations and EGFR fluorescent in situ hybridization analysis were without predictive value. Matuzumab and panitumumab have also been studied in phase II trials. Necitumumab, a fully human monoclonal antibody, is currently evaluated in combination with chemotherapy in two phase III trials in patients with advanced NSCLC. Cetuximab is also studied in combination with chemoradiotherapy in patients with locally advanced NSCLC.

Abstract
BACKGROUND To evaluate the safety and tolerability of two different weekly doses of the fully humanized epidermal growth factor receptor (EGFR)-targeting monoclonal antibody matuzumab combined with high-dose 5-fluorouracil, leucovorin and cisplatin (PLF) in the first-line treatment of patients with EGFR-positive advanced gastric and esophagogastric adenocarcinomas. METHODS Patients were treated in two matuzumab dose groups with the first cohort of patients receiving 400 mg matuzumab in combination with PLF. Based on the safety observations the next cohort of patients received 800 mg matuzumab. The study was conducted in two parts, with phase A, designed to assess the safety and tolerability of the combination, and phase B designed to be a treatment continuation for those patients benefiting from treatment. Treatment cycles were 7 weeks each. Each patient received the dose of matuzumab they were assigned to at study entry for the duration of the study. RESULTS Fifteen EGFR-positive patients were enrolled into the two matuzumab dose groups; 400 mg dose n=7; 800 mg dose n=8. All patients experienced at least one adverse event (AE). No patient experienced any serious AE which was considered to be related to matuzumab. Two grade 3 AEs possibly related to matuzumab occurred in 2 different patients (13.3 %), both in the 800 mg dose group. No dose-limiting toxicity (DLT) was observed in the 400 mg group. The maximum tolerated dose of matuzumab was not reached. The best confirmed overall response rate was 26.7 %. CONCLUSION Matuzumab, in combination with PLF, demonstrated an acceptable safety profile with modest anti-tumor activity.

Abstract
Treatment of advanced stage lung cancer is changing rapidly. With the new found knowledge on molecular targets such as the epidermal growth factor receptor (EGFR), effective therapy is now available in a selected population with the target mutation. Single-agent epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) is a standard first-line therapy for patients with activating-EGFR mutation such as base-pair deletion in exon 19 or point mutation at exon 21. At the same time, this class of drugs may be combined with chemotherapy. Studies on the concurrent combination of chemotherapy and EGFR-TKI confirmed a lack of efficacy. A phase II study on sequential intercalated combination has demonstrated an improvement in progression-free survival (PFS), but this needs to be validated by the ongoing phase III study. The third approach is to combine EGFR-TKI as maintenance therapy after tumour response or stable disease to cytotoxic chemotherapy. Two phase III studies have shown improvement in PFS, but the use of biomarkers for the selection of maintenance therapy remains debatable. Cetuximab is a monoclonal antibody against EGFR and its combination with chemotherapy was shown to improve overall survival in an unselected population. A new biomarker using the H-score will help to select patients for this combination.

Abstract
Monoclonal antibody (McAb) is the key tool for cancer immunodiagnosis and immunotherapy. McAb-based immunotherapy that targets tumor antigens has had great achivement. In this study, a cell clone which kept secreting high-titer IgG1-type McAb named NJ001 against human non-small cell lung cancer (NSCLC) cells was obtained. The titer of purified NJ001 was 2×106. The antigen named SP70 of NSCLC specifically identified by NJ001 was proved to be a protein with the relative molecular mass (Mr) of 70 kDa. The results of immunohistochemical staining indicated that NJ001 could positively react to NSCLC, but weak positively or negatively react to human small-cell lung cancer (SCLC), pulmonary pseudotumor and other epithelial tumors. In soft agar assay, the colony formation efficiency in NJ001 groups decreased in a dose-dependent manner. For the concentration of 100 µg/ml, 200 µg/ml and 400 µg/ml, the inhibition ratio of colony formation was 23.4%, 62.5% and 100% respectively. Meanwhile, NJ001 caused significant reduction in tumor volume and tumor weight compared to control mice in lung cancer xenograft model. The tumor growth inhibition ratio in 200 µg, 400 µg and 800 µg NJ001 groups was 10.44%, 37.29% and 44.04%, respectively. NJ001 also led to cytomorphological changes and induced the apoptosis of human lung adenocarcinoma cell line SPC-A1 significantly. The newly developed NJ001 selectively reacted to NSCLC and exhibited anti-tumor activity both in vitro and in vivo. NJ001 is of great value concerning immunodiagnostics and immunotherapy for NSCLC and holds promise for further research regarding the mechanism underlying tumor progression of NSCLC.

Abstract
Human papilloma virus (HPV), known to be an etiological agent for genital cancers, has been suggested also to be a possible contributory agent for lung cancer. Alternatively, lung cancer, formerly considered to be solely a smoker's disease, may now be more appropriately categorised into never smoker's and smoker's lung cancer. Through this paper we attempt to bring forth the current knowledge regarding mechanisms of HPV gaining access into the lung tissue, various strategies involved in HPV-associated tumorigenesis in lung tissue.

Abstract
The effects of bombesin receptor subtype-3 (BRS-3) agonists were investigated on lung cancer cells. The BRS-3 agonist (DTyr(6), (Ala(11), Phe(13), Nle(14)) bombesin(6-14) (BA1), but not gastrin releasing peptide (GRP) or neuromedin B (NMB) increased significantly the clonal growth of NCI-H1299 cells stably transfected with BRS-3 (NCI-H1299-BRS-3). Also, BA1 addition to NCI-H727 or NCI-H1299-BRS-3 cells caused Tyr(1068) phosphorylation of the epidermal growth factor receptor (EGFR). Similarly, (DTyr(6), R-Apa(11), Phe(13), Nle(14)) bombesin(6-14) (BA2) and (DTyr(6), R-Apa(11), 4-Cl,Phe(13), Nle(14)) bombesin(6-14) (BA3) but not gastrin releasing peptide (GRP) or neuromedin B (NMB) caused EGFR transactivation in NCI-H1299-BRS-3 cells. BA1-induced EGFR or ERK tyrosine phosphorylation was not inhibited by addition of BW2258U89 (BB(2)R antagonist) or PD168368 (BB(1)R antagonist) but was blocked by (DNal-Cys-Tyr-DTrp-Lys-Val-Cys-Nal)NH(2) (BRS-3 ant.). The BRS-3 ant. reduced clonal growth of NCI-H1299-BRS-3 cells. BA1, BA2, BA3 and BRS-3 ant. inhibit specific (125)I-BA1 binding to NCI-H1299-BRS-3 cells with an IC(50) values of 1.1, 21, 15 and 750nM, respectively. The ability of BRS-3 to regulate EGFR transactivation in NCI-H1299-BRS-3 cells was reduced by AG1478 or gefitinib (EGFR tyrosine kinase inhibitors), GM6001 (matrix metalloprotease inhibitor), PP2 (Src inhibitor), N-acetylcysteine (anti-oxidant), Tiron (superoxide scavenger) and DPI (NADPH oxidase inhibitor). These results demonstrate that BRS-3 agonists may stimulate lung cancer growth as a result of EGFR transactivation and that the transactivation is regulated by BRS-3 in a Src-, reactive oxygen and matrix metalloprotease-dependent manner.

Abstract
As with many cancers, early detection of head and neck cancer increases a patient's survival rate. If diagnosed early, its five-year survival nears 90% with standard therapy alone. Unfortunately, the average survival rate for head and neck cancer is low due to the difficulty in early detection and achieving a sustainable response. Conventional treatments are not adequate for the majority of advanced or recurrent head and neck cancer patients because of the remarkable resistance of tumors to chemotherapy and radiation, and the situation is especially devastating for the first time treatment failure. The major limitations of these treatments are the lack of specificity for the tumor cell and unacceptable toxicity to the patient. As a result, current research in therapeutics for advanced, chemotherapy-resistant or recurrent head and neck cancer patients has focused on new treatment modalities that exploit biological differences between tumor and normal cells. These therapies include monoclonal antibodies, molecular inhibitors, gene therapy and photodynamic therapy. This article reviews the current preclinical and clinical evidence of these experimental therapeutics as they relate to head and neck cancer.

Abstract
IMPORTANCE OF THE FIELD The management of non-small-cell lung cancer (NSCLC) has undergone a paradigm shift in the last decade, with the survival advantage demonstrated by the incorporation of anti-epidermal growth factor receptor (EGFR) agents to the standard treatment of advanced/metastatic NSCLC. AREAS COVERED IN THIS REVIEW We review the existing data regarding the distinct anti-EGFR agents in the NSCLC treatment and the potential role of the investigated biomarkers in the clinical outcome. WHAT THE READER WILL GAIN Tyrosine kinase inhibitors have been used in first-line, second-line and more settings with extremely good results in a subgroup of patients. Cetuximab remains the only anti-EGFR monoclonal antibody to show survival benefit when combined with a cytotoxic agent in the front-line setting. Anti-EGFR treatment is associated with a dramatic clinical benefit in a subgroup of patients, emphasizing the importance of customizing treatment. Several biomarkers have been investigated for their predictive or prognostic value. Validation of identification of biomarkers remains a focus of intense research that may ultimately guide therapeutic decision making, as none of these is considered ideal to discriminate responding from non-responding patients. However, the current evidence of the EGFR mutation analysis from a recent randomised trial suggests that EGFR mutation analysis is quite a good predictive marker for responsiveness to anti-EGFR TKIs. Moreover, the identification of surrogate markers to indicate optimal activity of the anti-EGFR agent is also needed. This review article provides data from large clinical trials using anti-EGFR agents and correlates these results with the tested biomarkers. TAKE HOME MESSAGE EGFR inhibition has shown very encouraging results and has improved the outcome of the NSCLC treatment. However, a plateau of significant clinical benefit seems to have been reached and we believe that the time to move away from the traditional treatment approach to more individualizing therapies has come.

Abstract
Blockade of the epidermal growth factor receptor (EGFR) by monoclonal antibodies is a strategy to improve outcome in patients with non-small cell lung cancer. Cetuximab, a chimeric anti-EGFR monoclonal antibody, has been studied in combination with different chemotherapy protocols in both phase II and phase III trials in patients with advanced NSCLC. In the phase III FLEX trial, cetuximab added to cisplatin/vinorelbine resulted in an absolute overall survival benefit of 1.2 months compared to the same chemotherapy alone in patients with advanced EGFR-expressing NSCLC. In the second phase III trial, cetuximab added to carboplatin plus paclitaxed failed to improve progression-free survival but suggested a survival benefit similar to that seen in the FLEX trial. However, the benefit in survival reached statistical significance only in the FLEX trial. A meta-analysis that included patients from four randomized trials confirmed the efficacy of cetuximab when added to chemotherapy. Thus addition of cetuximab to platinum-based chemotherapy represents a new treatment option for patients with advanced NSCLC. Matuzumab and panitumumab have also been evaluated in phase II trials. Necitumumab is currently evaluated in combination with chemotherapy in two randomized phase III trials.

Abstract
As early detection strategies have not been successful, most patients with head and neck cancer (HNC) present with advanced (stages III and IV) disease. Oral cavity tumors are treated primarily with surgical resection and advanced tumors of the pharynx and larynx are generally treated with combined modality therapy (chemoradiation). The major advances in the management of HNC have evolved from the integration of targeted therapeutics into treatment regimens. Presently, the most important target for new therapeutic strategies in HNC is the epidermal growth factor receptor (EGFR) and so far only cetuximab, a monoclonal antibody targeting EGFR, has been approved by the United States Food and Drug Administration in the HNC population as a radiation-sensitizing agent for patients undergoing primary radiation-based treatment and for patients with recurrent or metastatic disease. Other receptor and non-receptor kinase targeting strategies are under active clinical investigation as well. The increasing number of molecular targeting strategies in clinical development underscores the need to identify which HNC patients will respond to specific therapies. This article focuses on the current preclinical and clinical evidence of monoclonal antibodies targeting EGFR in HNC. We will first review the mechanisms of action of cetuximab, its clinical trials and side-effect profiles, and its present clinical application. Then, the current development status of other molecular antibodies and two molecular inhibitors, gefitinib and erlotinib, will be examined. Finally, by focusing on cetuximab, the current issues in EGFR targeting will be reviewed and we propose future directions of EGFR targeting. We hope that this review will provide further insight into the future directions of targeted therapy in the management of advanced HNC.

Abstract
BACKGROUND Clinical data showed promising antitumour activity with feasible tolerability for matuzumab plus epirubicin, cisplatin and capecitabine (ECX) chemotherapy in untreated advanced oesophago-gastric (OG) cancer. The aim was to evaluate the efficacy of matuzumab plus ECX versus ECX alone. PATIENTS AND METHODS In this multicentre, randomised open-label phase II study, 72 patients with metastatic OG cancer were randomly assigned to either 800 mg matuzumab weekly plus epirubicin 50 mg/m², cisplatin 60 mg/m² on day 1 and capecitabine 1250 mg/m² daily in a 21-day cycle (ECX) or the same ECX regimen alone. The primary end point was objective response. Secondary end points included progression-free survival (PFS), overall survival (OS), quality of life, safety and tolerability. RESULTS Following random assignment, 35 patients (median age 59 years) received ECX/matuzumab and 36 patients (median age 64 years) ECX. The addition of matuzumab to ECX did not improve objective response: 31% for ECX/matuzumab [95% confidence interval (CI) 17-49] compared with 58% for the ECX arm (95% CI 41-74) P = 0.994 (one sided). There was no significant difference in median PFS: 4.8 months (95% CI 2.9-8.1) for ECX/matuzumab versus 7.1 months (95% CI 4.4-8.5) for ECX, or in median OS: 9.4 months (95% CI 7.5-16.2), compared with 12.2 months (95% CI 9.8-13.8 months). Grade 3/4 treatment-related toxicity was observed in 27 and 25 patients in the ECX/matuzumab and ECX groups, respectively. CONCLUSION Matuzumab 800 mg weekly combined with ECX chemotherapy does not increase response or survival for patients with advanced OG cancer. Therefore, ECX/matuzumab should not be examined further in phase III trials.

Abstract
Chemotherapy used to be the only available option to fight advanced nonsmall cell lung cancer. Platinum-based medication combined with taxanes, vinca alkaloids, and antimetabolites improved patient survival rates. Unfortunately, neoplasmatic diseases remain a global killer because chemotherapy benefits have reached a plateau and most patients are diagnosed at the metastatic stage. The urgent need for therapeutic agents, along with advances in the knowledge of the molecular events of oncogenesis, has resulted in the development of medication that specifically targets processes and pathways critical for tumor growth, such as angiogenesis and the epidermal growth factor receptor. Initially, inhibiting these pathways managed to prolong patient survival, although not to the extent desired. Moreover, targeted therapy combined with conventional cytotoxic agents has shown no superiority to chemotherapy alone in terms of patient survival. Hence, numerous multidynamic agents have appeared in the hope that they might help fight nonsmall cell lung cancer. However, no group of patients who will hopefully gain maximum benefit from such interventions has been clearly identified yet. This paper presents current evidence with regard to such novel agents and angiogenesis and epidermal growth factor inhibitors.

Abstract
Lung cancer is the leading cause of cancer death in men and women. In 2008, in the US > 200,000 patients were diagnosed with lung cancer and > 160,000 died from their disease. Over 80% of lung cancers are of the non-small cell type, for which chemotherapy has demonstrated modest survival benefits at all stages of disease. Agents that alter critical molecular cell growth pathways are a growing area of research and development including targeted therapies directed at the EGFR. Downstream effects of EGFR dimerization and activation include cell proliferation, differentiation and angiogenesis, key events in the malignant process. Two main classes of drugs have been developed, small molecule tyrosine kinase inhibitors (TKIs) and monoclonal antibodies directed against the extracellular domain of the receptor. This review discusses clinical studies with several new therapies and the plans for drug development.

Abstract
Cytotoxic chemotherapy treatment for patients with advanced non-small-cell lung cancer (NSCLC) has reached a plateau, but further improvements are expected with integration of targeted therapies. Epidermal growth factor receptor (EGFR)-directed therapies are of particular interest because the EGFR is frequently expressed in tumors and associated with poorer outcome. Thus, blockade of the EGFR should improve outcome. Blockade can be achieved by tyrosine kinase inhibitors (TKIs) or monoclonal antibodies (MoAbs). Both approaches have been evaluated in advanced NSCLC. As single agents, EGFR-directed TKIs have demonstrated efficacy in patients previously treated with chemotherapy. When combined with first-line platinum-based chemotherapy, TKIs failed to improve the outcome. In contrast, MoAbs in combination with platinum-based first-line chemotherapy showed promising efficacy in phase II trials. Two phase III trials with chemotherapy with or without cetuximab have been performed in patients with advanced NSCLC. Other EGFR-directed MoAbs and TKIs are in earlier stages of clinical development.

Abstract
The identification of certain molecular mechanisms underlying lung carcinogenesis and progression has led to the development of targeted agents against different families of growth factors and receptors. The epidermal growth factor receptor (EGFR) is one such target for therapeutic exploitation. Inhibition of EGFR downstream signaling can be accomplished through two primary mechanisms: (a) the direct blocking of intracellular kinase activity with small-molecule tyrosine kinase inhibitors (TKIs) (e.g., gefitinib, erlotinib) and (b) the blocking of EGFR ligand binding using antibodies directed against the extracellular domain of the receptor (e.g., cetuximab). Resistance to available EGFR-targeted treatments has emerged as a substantial clinical issue in non-small cell lung cancer (NSCLC). Several novel agents with the potential to overcome such resistance are currently in clinical development, including irreversible EGFR TKIs, monoclonal antibodies, and TKIs directed against multiple signaling pathways. Here we discuss the clinical application of the currently available EGFR-targeted agents in NSCLC, the underlying mechanisms of resistance, and the novel agents in clinical development that may overcome resistance.

Abstract
Non-small cell lung cancer (NSCLC) is a major global health problem and represents the leading cause of cancer-related deaths worldwide. The majority of patients with NSCLC are diagnosed with advanced-stage disease, and the prognosis for such patients is poor. The currently approved cytotoxic chemotherapy is associated with substantial limitations in both efficacy and safety. The availability of agents targeted against the epidermal growth factor receptor (EGFR), as well as the antiangiogenic agent bevacizumab, have provided some clinical benefit. Nonetheless, the efficacy of these agents is also inadequate, and resistance has emerged as a clinical problem. Numerous novel targeted therapies are now in clinical development and may have potential for overcoming the limitations associated with currently available agents. In this article we review clinical data for molecular-targeted therapies in NSCLC, with emphasis on EGFR inhibitors and antiangiogenic agents.

Abstract
Non-small cell lung cancer (NSCLC) accounts for about 85% of all new diagnoses of lung cancer. Unfortunately, few NSCLC patients are suitable for radical treatment for curative intent. Because most patients with NSCLC have advanced disease at diagnosis, chemotherapy represents the standard of care, although, to date, a plateau has been reached with this approach. Improvements in the knowledge of tumor biology and mechanisms of oncogenesis have identified the epidermal growth factor receptor (EGFR), a member of the ErbB family, as a molecular target for NSCLC treatment. EGFR is commonly overexpressed in NSCLC and has been associated with impaired prognosis; therefore, its inhibition may lead, through the suppression of tumor proliferation, to improvement in clinical outcomes. Strategies to block EGFR include tyrosine kinase inhibitors, monoclonal antibodies, ligand-linked toxins, and antisense approaches. This article focuses on the treatment of NSCLC with the anti-EGFR monoclonal antibodies, including cetuximab, for which the largest amount of data in the literature exists. Recently, a phase III randomized trial performed in advanced NSCLC patients yielded a statistically significant survival advantage for patients treated with cetuximab plus chemotherapy versus chemotherapy alone. Other anti-EGFR monoclonal antibodies, such as panitumumab, matuzumab, nimotuzumab, and ch806, are in different stages of development for the treatment of advanced NSCLC.

Abstract
To evaluate the safety, tolerability, efficacy, pharmacokinetics and pharmacodynamics of the humanised antiepidermal growth factor receptor monoclonal antibody matuzumab combined with epirubicin, cisplatin and capecitabine (ECX) in patients as first-line treatment for advanced oesophagogastric cancer that express epidermal growth factor receptor (EGFR). This was a phase I dose escalation study of matuzumab at 400 and 800 mg weekly and 1200 mg every 3 weeks combined with ECX (epirubicin 50 mg m−2, cisplatin 60 mg m−2 on day 1 and capecitabine 1000 mg m−2 daily). Patients were treated until disease progression, unacceptable toxicity or for a maximum of eight cycles. Twenty-one patients were treated with matuzumab at three different dose levels (DLs) combined with ECX. The main dose-limiting toxicity (DLT) was grade 3 lethargy at 1200 mg matuzumab every 3 weeks and thus 800 mg matuzumab weekly was the maximum-tolerated dose (MTD). Other common toxicities included rash, nausea, stomatitis and diarrhoea. Pharmacokinetic evaluation demonstrated that the coadministration of ECX did not alter the exposure of matuzumab. Pharmacodynamic studies on skin biopsies demonstrated inhibition of the EGFR pathway. Objective response rates of 65% (95% confidence interval (CI): 43–82), disease stabilisation of 25% (95% CI: 11–47) and a disease control rate (CR+PR+SD) of 90% were achieved overall. The MTD of matuzumab in combination with ECX was 800 mg weekly, and at this DL it was well-tolerated and showed encouraging antitumour activity. At the doses evaluated in serial skin biopsies, matuzumab decreased phosphorylation of EGFR and MAPK, and increased phosphorylation of STAT-3.

Abstract
Antibodies targeting epidermal growth factor receptor (EGFR) have proven to be effective in patients with non-small cell lung cancer (NSCLC) that express EGFR. We recently published a phase I study of weekly matuzumab plus paclitaxel. This therapy was well tolerated and showed clinical responses in the majority of patients. Although matuzumab displays potent antitumor activity in some patients, not all patients respond well to treatment. Whether dysregulation of EGFR-mediated pathways precludes or sensitizes cells to paclitaxel is unknown. We sought to determine molecular predictive factors for therapy response in a phase I/II study patient cohort treated with matuzumab+/-paclitaxel. Twenty-three cases [including one complete response (CR), three partial responses (PR), 10 stable diseases (SD)] were screened using immunohistochemistry (IHC), fluorescence in situ hybridization (FISH), PCR/sequencing and denaturing wave high performance liquid chromatography (D-HPLC) for expression, amplification, and mutation status of EGFR and downstream signaling pathways. All patients with PR or CR displayed an either high overall or single-cell EGFR expression in the majority of cells. In addition, all of the moderate responders, who achieved SD after at least two cycles of therapy, showed diffuse EGFR expression rates and/or strong single-cell EGFR expression. In contrast, 44% of the nonresponders showed low overall or single-cell EGFR expression levels. No low-expressing EGFR cases were present within the responder group. In addition, among patients with a gain-of-function mutation in KRAS primary therapy failure and/or short responses to therapy were observed. Our data suggest that EGFR expression and KRAS mutation status is predictive for clinical response to matuzumab +/- paclitaxel in patients with advanced NSCLC.

Abstract
This review focuses on the recent advances in clinical data regarding antibody-based therapy in the management of solid tumors. We also discuss perspectives on antibody-based therapy in the future. Thorough understanding of the complex interactions between components of the immunological response has led to interest in the concept of immune-mediated therapy for solid tumors. Over the last few years, several humanized and chimeric monoclonal antibodies (MAbs) targeting human epidermal receptor 2 (HER2), epidermal growth factor receptor (EGFR), and vascular endothelial growth factor (VEGF) have been employed in treating solid tumors, including breast, colorectal, lung, head and neck, and gynecologic cancers. Trastuzumab, bevacizumab, cetuximab, and panitumumab are MAbs that are most widely used in clinical practice with acceptable rates of adverse events. Combination of MAbs with small-molecule inhibitors of the same pathway could potentially increase the efficacy and specificity of antibody-based treatment. Immune-mediated effects may be further exploited with the use of bivalent molecules.

Abstract
Lung cancer is the leading cause of cancer deaths world-wide. Recent advances in cancer biology have led to the identification of new targets in neoplastic cells and the development of novel targeted therapies. At this time, two targeted agents are approved by the FDA in advanced non-small cell lung cancer (NSCLC): the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) erlotinib, and the anitangiogenic bevacizumab. A third agent, cetuximab, which was recently shown to enhance survival when used with cisplatin and vinorelbine as first line therapy for advanced NSCLC, will likely be approved by regulatory agencies. With more than 500 molecularly targeted agents under development, the prospects of identifying novel therapies that benefit individual patients with lung cancer are bright.

Abstract
Background Antibody-based immuneotherapy has achieved some success for cancer. But the main problem is that only a few tumor-associated antigens or therapeutic targets have been known to us so far. It is essential to identify more immunogenic antigens (especially cellular membrane markers) for tumor diagnosis and therapy. Methods The membrane proteins of lung adenocarcinoma cell line A549 were used to immunize the BALB/c mice. A monoclonal antibody 4E7 (McAb4E7) was produced with hybridoma technique. MTT cell proliferation assay was carried out to evaluate the inhibitory effect of McAb4E7 on A549 cells. Flow cytometric assay, immunohistochemistry, western blot and proteomic technologies based on 2-DE and mass spectrometry were employed to detect and identify the corresponding antigen of McAb4E7. Results The monoclonal antibody 4E7 (McAb4E7) specific against A549 cells was produced, which exhibited inhibitory effect on the proliferation of A549 cells. By the proteomic technologies, we identified that ATP synthase beta subunit (ATPB) was the corresponding antigen of McAb4E7. Then, flow cytometric analysis demonstrated the localization of the targeting antigen of McAb4E7 was on the A549 cells surface. Furthermore, immunohistochemstry showed that the antigen of McAb4E7 mainly aberrantly expressed in tumor cellular membrane in non-small cell lung cancer (NSCLC), but not in small cell lung cancer (SCLC). The rate of ectopic expressed ATPB in the cellular membrane in lung adenocarcinoma, squamous carcinoma and their adjacent nontumourous lung tissues was 71.88%, 66.67% and 25.81% respectively. Conclusion In the present study, we identified that the ectopic ATPB in tumor cellular membrane was the non-small cell lung cancer (NSCLC) associated antigen. ATPB may be a potential biomarker and therapeutic target for the immunotherapy of NSCLC.

Abstract
PURPOSE The epidermal growth factor receptor ErbB-1 is commonly expressed in pancreatic cancer and ErbB-1 targeting has shown promising results. We wanted to evaluate matuzumab (EMD72000), a fully humanized ErbB-1-specific monoclonal antibody in combination with gemcitabine in experimental pancreatic cancer. EXPERIMENTAL DESIGN Using the human pancreatic cancer cell line L3.6pl, we investigated matuzumab in vitro and in vivo. ErbB-1 phosphorylation and downstream pathway activation were evaluated by Western blot. Proliferation and migration assays and fluorescence-activated cell sorting analysis were done. For in vivo studies, we used an orthotopic nude mice model in which 40 mg/kg of matuzumab+/-100 mg/kg of gemcitabine were administered twice weekly. Different treatment durations (7, 14, 21, and 25 days) and varying time points of treatment initiation (days 8, 15, 22, and 29) were evaluated. Ki67, CD31, and phosphorylated p44/42 mitogen-activated protein kinase (MAPK) immunohistochemistry were done. RESULTS ErbB-1 phosphorylation and downstream MAPK and AKT signaling were significantly reduced by matuzumab. Matuzumab significantly inhibited proliferation and migration in vitro, and induced tumor cell apoptosis in a dose-dependant manner. Matuzumab therapy significantly lowered tumor volume in vivo, reduced lymph node and liver metastases, and decreased microvessel density and tumor cell proliferation. These effects were significantly enhanced when gemcitabine was added. A significant and prolonged antitumor activity was even evident with short-term therapy (7 days) and with a late onset of therapy (day 22 after tumor cell injection). CONCLUSIONS Matuzumab is an effective agent with long-lasting antiproliferative, proapoptotic, antiangiogenic, and antimetastatic activity in human pancreatic cancer models. These effects might be potentiated by gemcitabine.

Abstract
Epidermal growth factor receptor (EGFR) inhibitors have been proven to improve survival in advanced non-small cell lung cancer patients, even after failure of previous chemotherapy. However, how to identify the patients, who will benefit from this treatment, is still not known. Clinical and demographic factors, i.e., females, never-smokers, patients with Asian ethnicity, or histology of adenocarcinoma, seem all to be favorable factors for clinical outcome, but not sufficient for patient selection. Increased EGFR gene copy number detected by fluorescence in situ hybridization has consistently been shown in several retrospective studies to be a good predictive "marker," especially for EGFR tyrosine kinase inhibitors. Nevertheless, most of the data obtained so far are retrospective, and prospective validation is ongoing. The current review summarizes the clinical data based on the first generation EGFR inhibitors and discusses future strategies for exploring the role of EGFR fluorescence in situ hybridization as a selection marker for EGFR inhibitor therapy in non-small cell lung cancer.
