Abstract
Nowadays, lung cancer is still the deadliest oncological disease in the world. Among them, non-small cell lung cancer (NSCLC) accounts for 80%∼85% of all lung cancers, and its 5-year survival rate is less than 15%, making the situation critical. In the past decades, despite some clinical advances in conventional treatments, the overall survival rate of NSCLC is still not optimistic due to its unique physiological conditions and the frequent occurrence of tumor escape. In recent years, immunotherapy has become a new hot spot in lung cancer research, including antibody therapy and cell therapy, which have been developed and utilized one after another, especially immune checkpoint inhibitor (ICI). These approaches have effectively improved the overall survival rate and objective response rate of NSCLC patients by enhancing the immune capacity of the body and targeting tumor cells more effectively, which is more specific and less toxic compared with conventional chemotherapy, and providing more strategies for NSCLC treatment. In this paper, we reviewed the relevant targets, clinical progress and adverse reaction in monoclonal antibodies, antibody-drug conjugates, ICI, bispecific antibodies, T-cell receptor engineered T cell therapy (TCR-T), Chimeric antigen receptor T-cell immunotherapy (CAR-T), and also report on their combination therapy from the immune-related background to provide better NSCLC treatment and prospective.

Abstract
BACKGROUND The use of standard cytotoxic chemotherapy seems to have reached a "treatment plateau". The application of anti-epidermal growth factor receptor (EGFR) monoclonal antibodies (mAbs) is a new strategy for non-small-cell lung cancer (NSCLC) therapy. We aimed to comprehensively assess the efficacy and safety of anti-EGFR-mAbs plus chemotherapy as first-line therapy for advanced NSCLC. METHODS According to inclusion and exclusion criteria, we conducted a comprehensive literature search of electronic databases. From the included trials, information on overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and adverse events (AEs) was extracted. RESULTS The research showed that compared with chemotherapy alone, anti-EGFR-mAb plus chemotherapy combinations significantly improved OS (HR = 0.88, 95%CI: 0.83-0.94, P < .0001), PFS (HR = 0.89, 95%CI: 0.83-0.95, P = 0.0004) and ORR (OR = 1.39, 95%CI: 1.13-1.69, P = .001). Meta subgroup analyses manifested that the OS of patients with squamous NSCLC treated with anti-EGFR-mAb plus chemotherapy combinations was notably better than that of patients with non-squamous NSCLC treated with the same combinations (HR = 0.82, 95%CI: 0.73-0.92, P = .0005). Compared with the chemotherapy group, combination of chemotherapy and anti-EGFR mAb showed increase in incidences of severe AEs (> = grade 3) that mainly include, leukopenia (OR = 1.53, 95%CI: 1.28-1.82, P < .00001), febrile neutropenia (OR = 1.35, 95%CI: 1.06-1.71, P = .02), hypomagnesemia (OR = 5.68, 95%CI: 3.54-9.10, P < .00001), acneiform rash (OR = 35.88, 95%CI: 17.37-74.10, P < .00001), fatigue (OR = 1.24, 95%CI: 1.02-1.49, P = .03), diarrhea (OR = 1.69, 95%CI: 1.16-2.47, P = .006), and infusion-related reactions (OR = 3.78, 95%CI: 1.93-7.41, P = .0001). CONCLUSION Adding an anti-EGFR-mAb to the standard platinum-based chemotherapy regimens used for the first-line treatment of advanced NSCLC resulted in statistically notable improvements in OS, PFS, and ORR. In particular, anti-EGFR-mAb and chemotherapy combinations achieved greater survival benefits in patients with squamous NSCLC than in those with non-squamous NSCLC. In addition, the safety profile of chemotherapy plus anti-EGFR-mAb combinations was acceptable compared to that of chemotherapy alone.

Abstract
The epidermal growth factor receptor (EGFR) is a tyrosine kinase receptor that plays an important role in normal epidermal cell physiology. EGFR is overexpressed in cancer cells and has a number of mutations that implicate tumor malignancy, development, and poor patient prognosis; thus, EGFR is an attractive target for cancer therapy. At present, anti-EGFR monoclonal antibodies (mAbs) have been approved and are used for treating patients with a variety of EGFR-expressing cancers. Epitope mapping is important in identifying the therapeutic mechanism of anti-EGFR mAbs; however, the development of epitope mapping techniques lags behind the development of antimolecular target mAbs, including anti-EGFR mAbs. Hence, in this study, a novel epitope mapping method, RIEDL insertion for epitope mapping (REMAP) method, was developed. The results of this study demonstrated that the critical epitope of anti-EGFR mAb EMab-134 is Gly378, Asp379, Ser380, Phe381, Thr382, His383, Thr384, Pro385, and Pro386 of EGFR. The REMAP method could be useful for determining the critical epitope of functional mAbs against many target molecules.

Abstract
Protein tyrosine phosphorylation is key to activation of receptor tyrosine kinases (RTK) that drive development of some cancers. One challenge of RTK-targeted therapy is identification of those tumors that express non-mutated but activated RTKs. Phosphotyrosine (pTyr) RTK levels should be more predictive of the latter than expressed total protein. Western blotting (WB) with a pTyr antibody and enhanced chemiluminescence (ECL) detection is sufficiently sensitive to detect pTyr-RTKs in human tumor homogenates. Presentation of results by comparing WB images, however, is wanting. Here we describe the preparation of a new pTyr-protein standard, pTyr-ALK48-SB (pA), derived from a commercial anaplastic lymphoma kinase (ALK) recombinant fragment, and its use to quantify pTyr-epidermal growth factor receptor (pTyr-EGFR) in commercial A431 cell lysates. Linearity of one-dimensional (1D) WB plots of pA band density versus load as well as its lower level of detection (0.1 ng, 2 fmole) were determined for standardized conditions. Adding pA to two lots of A431 cell lysates with high and low pTyr-EGFR allowed normalization and quantification of the latter by expressing results as density ratios for both 1D and 2D WB. This approach is semi-quantitative because unknown RTKs may be outside the linear range of detection. Semiquantitative ratios are an improvement over comparisons of images without a reference standard and facilitate comparisons between samples.

Abstract
Cancer is currently the second leading cause of death globally and is expected to be responsible for approximately 9.6 million deaths in 2018. With an unprecedented understanding of the molecular pathways that drive the development and progression of human cancers, novel targeted therapies have become an exciting new development for anti-cancer medicine. These targeted therapies, also known as biologic therapies, have become a major modality of medical treatment, by acting to block the growth of cancer cells by specifically targeting molecules required for cell growth and tumorigenesis. Due to their specificity, these new therapies are expected to have better efficacy and limited adverse side effects when compared with other treatment options, including hormonal and cytotoxic therapies. In this review, we explore the clinical development, successes and challenges facing targeted anti-cancer therapies, including both small molecule inhibitors and antibody targeted therapies. Herein, we introduce targeted therapies to epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF), human epidermal growth factor receptor 2 (HER2), anaplastic lymphoma kinase (ALK), BRAF, and the inhibitors of the T-cell mediated immune response, cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell death protein-1 (PD-1)/ PD-1 ligand (PD-1 L).

Abstract
INTRODUCTION Lung cancer represents the most common cause of cancer death worldwide. While the prognosis remains poor, immunotherapy is giving a positive impact on survival. Cancer vaccines represent a form of active immunotherapy that historically has given modest results in terms of efficacy. The overexpression of the EGFR by tumor cells was reported in more than half of cases of lung cancer, representing a mechanism of cancerogenesis. CIMAvax-EGF, a therapeutic vaccine for non-small cell lung cancer (NSCLC) developed in Cuba, consists of a human recombinant EGF able to induce antibodies against the autologous EGF, resulting in serum EGF withdrawal and lower EGF-EGFR interaction. Area covered: We critically reviewed the existing literature about CIMAvax-EGF, from the Pilot studies to the efficacy controlled studies. We also overviewed the ongoing trials. Expert opinion: CIMAvax-EGF demonstrated to be safe and immunogenic. In a phase III randomized study CIMAvax-EGF, used as a switch maintenance treatment after platinum-based chemotherapy, did not significantly improve survival. Current data are not sufficient to recommend CIMAvax-EGF as a treatment option for advanced stage NSCLC. Further studies, conducted in a context of worldwide standardized clinical practice, are needed to better define if a subpopulation of patients can benefit from the vaccination.

Abstract
Antibodies have proven their high value in antitumor therapy over the last two decades. They are currently being used as the first-choice to treat some of the most frequent metastatic cancers, like HER2+ breast cancers or colorectal cancers, currently treated with trastuzumab (Herceptin) and bevacizumab (Avastin), respectively. The impressive therapeutic success of antibodies inhibiting immune checkpoints has extended the use of therapeutic antibodies to previously unanticipated tumor types. These anti-immune checkpoint antibodies allowed the cure of patients devoid of other therapeutic options, through the recovery of the patient’s own immune response against the tumor. In this review, we describe how the antibody-based therapies will evolve, including the use of antibodies in combinations, their main characteristics, advantages, and how they could contribute to significantly increase the chances of success in cancer therapy. Indeed, novel combinations will consist of mixtures of antibodies against either different epitopes of the same molecule or different targets on the same tumor cell; bispecific or multispecific antibodies able of simultaneously binding tumor cells, immune cells or extracellular molecules; immunomodulatory antibodies; antibody-based molecules, including fusion proteins between a ligand or a receptor domain and the IgG Fab or Fc fragments; autologous or heterologous cells; and different formats of vaccines. Through complementary mechanisms of action, these combinations could contribute to elude the current limitations of a single antibody which recognizes only one particular epitope. These combinations may allow the simultaneous attack of the cancer cells by using the help of the own immune cells and exerting wider therapeutic effects, based on a more specific, fast, and robust response, trying to mimic the action of the immune system.

Abstract
Recently, tyrosine kinase inhibitors (TKIs) have been recommended as a first-line treatment for advanced non-small cell lung cancer (NSCLC), significantly improving the treatment outcomes of lung adenocarcinoma patients with the EGFR mutation. However, the application of TKIs for lung squamous cell carcinoma (SCC), the second largest pathological subtype of NSCLC, remains controversial because available data for the EGFR mutation profile and frequency in SCC patients are limited. In this study, 89 bronchoscopic-biopsy specimens from Chinese SCC male patients were assayed for EGFR exon 19 mutation, using improved polymerase chain reaction-denature gel gradient electrophoresis. EGFR exon 19 mutations were detected in 77 of 89 (86.5%) patients, and included six kinds of point mutations (11.6%) and two deletions (Del_747-751 [64.9%] and Del_746-751 [23.3%]). We found that the proportion of mutated EGFR varied from 0.98% to 100% in positive specimens and increased with the development of the disease. The difference of proportion between Stage IV patients and Stage II patients or Stage III patients was significant (P<0.001). These results provided valuable clues to explain the reason why patients harboring the same mutation responded distinctly to TKI treatment. Del_747-751 and Del_746-751 were the dominant mutations in the assayed SCC patients (76.4%), and both belong to the EGFR-TKI-sensitive mutation. Recently research demonstrated that Del_746-751 patients have better response to EGFR-TKI than Del_L747-751 patients. However, our study indicated that majority of SCC patients (55.5%) carried Del_ L747-751. We suggest that the unique clinic features of SCC should be further studied to reveal the mechanism of poorer treatment outcome of EGFR-TKI therapy, and that a better treatment plan and more specific, potent targeted drugs for lung SCC need to be developed.

Abstract
Molecular techniques have improved our understanding of the pathogenesis of cancer development. These techniques have also fueled the rational development of targeted drugs for patient populations stratified by their genetic characteristics. These novel methods have changed the classic paradigm of diagnostic pathology; among them are IHC, FISH, polymerase chain reaction (PCR) and microarray technology. IHC and FISH detection methods for human epidermal growth factor receptor-2 (HER2), epidermal growth factor receptor (EGFR) and programmed death ligand-1 (PD-L1) were recently approved by the Food and Drug Administration (FDA) as routine clinical practice for cancer patients. Here, we discuss general challenges related to the predictive power of these molecular biomarkers for targeted therapy in cancer medicine. We will also discuss the prospects of utilizing new biomarkers for fibroblast growth factor receptor (FGFR) and hepatocyte growth factor receptor (cMET/MET) targeted therapies for developing new and robust predictive biomarkers in oncology.

In recent years, progress has been made in the characterization of natural killer (NK) cells in lung malignancies, and we have now gained a better understanding of the frequency, localization, phenotype, and functional status of NK cells infiltrating these tumors. NK cell subset recruited in lung cancer is mainly capable of producing relevant cytokines rather than exerting direct cancer cell killing. Thus, the relevance of NK cells in tumor microenvironment might also go beyond the killing of tumor cells, being NK cells endowed with regulatory functions toward an ample array of immune effectors. Nevertheless, boosting their cytotoxic functions and redirecting the migration of cytotoxic NK cell subset to the tumor site might open new therapeutic avenues for lung cancer. Also, we believe that a deeper investigation into the impact of both conventional (e.g., chemotherapy) or new therapies (e.g., anti-immune checkpoints mAbs) on NK cell homeostasis in lung cancer patients is now required.
