Abstract
Lung cancer is one of the commonest cancers with a significant mortality rate for both genders, particularly in men. Lung cancer is recognized as one of the leading causes of death worldwide, which threatens the lives of over 1.6 million people every day. Although cancer is the leading cause of death in industrialized countries, conventional anticancer medications are unlikely to increase patients' life expectancy and quality of life significantly. In recent years, there are significant advances in the development and applications of nanotechnology in cancer treatment. The superiority of nanostructured approaches is that they act more selectively than traditional agents. This progress led to the development of a novel field of cancer treatment known as nanomedicine. Various formulations based on nanocarriers, including lipids, polymers, liposomes, nanoparticles and dendrimers have opened new horizons in lung cancer therapy. The application and expansion of nano-agents lead to an exciting and challenging research era in pharmaceutical science, especially for the delivery of emerging anti-cancer agents. The objective of this review is to discuss the recent advances in three types of nanoparticle formulations for lung cancer treatments modalities, including liposomes, polymeric micelles, and dendrimers for efficient drug delivery. Afterward, we have summarized the promising clinical data on nanomaterials based therapeutic approaches in ongoing clinical studies.

Abstract
We presented a 67-year-old nonsmoking female lung adenocarcinoma patient with novel epidermal growth factor receptor (EGFR) A289G/F287_G288insHA cis mutations who responded positively to sintilimab combined with regorafenib and albumin paclitaxel, and sequential treatment of icotinib. Gene mutations in patients were detected by next-generation sequencing (NGS) technology, and changes in gene mutations before and after treatments were observed by ctDNA monitoring. We observed the efficacy of the patient through chest computed tomography (CT) imaging and carcinoembryonic antigen (CEA) level and found that the patient benefited from immunotherapy in combination with antiangiogenesis and chemotherapy for more than 1 year, CEA levels initially fell sharply and then rebounded during the treatment period. After changing to EGFR-TKI therapy, the CEA level of the patient does not only decreased sharply at the initial stage of treatment but also rebounded and increased at the later stage of treatment. The patient was tested for genetic mutations after 4 months of sequential EGFR-TKI therapy and was found to have lost all previous EGFR mutations, which may be the cause of resistance to targeted drug icotinib. We believe that our findings have enriched the EGFR mutation spectrum in NSCLC and highlighted the possible choice for patients harboring this mutation by immunotherapy combined with chemotherapy and antivascular therapy, and EGFR-TKI-targeted therapy.

Inhalable polymeric micro and nano-immunoadjuvants for developing therapeutic vaccines in the treatment of non-small cell lung cancer. Curr Pharm Des 2021; 28:395-409. [PMID: 34736378 DOI: 10.2174/1381612827666211104155604] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2021] [Revised: 08/24/2021] [Accepted: 08/24/2021] [Indexed: 12/24/2022]
Abstract
Non-small cell lung cancer (NSCLC) is a leading cause of death in millions of cancer patients. Lack of diagnosis at an early stage in addition to no specific guidelines for its treatment, and a higher rate of treatment-related toxicity further deteriorate the conditions. Current therapies encompass surgery, chemotherapy, radiation therapy, and immunotherapy according to the pattern and the stage of lung cancer. Among all, with a longlasting therapeutic action, reduced side-effects, and a higher rate of survival, therapeutic cancer vaccine is a new, improved strategy for treating NSCLC. Immunoadjuvants are usually incorporated into the therapeutic vaccines to shield the antigen against environmental and physiological harsh conditions in addition to boosting the immune potential. Conventional immunoadjuvants are often associated with an inadequate cellular response, poor target specificity, and low antigen load. Recently, inhalable polymeric nano/micro immunoadjuvants have exhibited immense potential in the development of therapeutic vaccines for the treatment of NSCLC with improved mucosal immunization. The development of polymeric micro/nano immunoadjuvants brought a new era for vaccines with increased strength and efficiency. Therefore, in the present review, we explained the potential application of micro/nano immunoadjuvants for augmenting the stability and efficacy of inhalable vaccines in the treatment of NSCLC. In addition, the role of biodegradable, biocompatible, and non-toxic polymers has also been discussed with case studies.

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.

AGR2, a unique tumor-associated antigen, is a promising candidate for antibody targeting. Oncotarget 2019; 10:4276-4289.

Abstract
Anterior gradient 2 (AGR2), a protein disulfide isomerase, shows two subcellular localizations: intracellular (iAGR2) and extracellular (eAGR2). In healthy cells that express AGR2, the predominant form is iAGR2, which resides in the endoplasmic reticulum. In contrast, cancer cells secrete and express eAGR2 on the cell surface. We wanted to test if AGR2 is a cancer-specific tumor-associated antigen. We utilized two AGR2 antibodies, P3A5 and P1G4, for in vivo tumor localization and tumor growth inhibition. The monoclonal antibodies recognized both human AGR2 and mouse Agr2. Biodistribution experiments using a syngeneic mouse model showed high uptake of P3A5 AGR2 antibody in xenografted eAgr2+ pancreatic tumors, with limited uptake in normal tissues. In implanted human patient-derived eAGR2+ pancreatic cancer xenografts, tumor growth inhibition was evaluated with antibodies and Gemcitabine (Gem). Inhibition was more potent by P1G4 + Gem combination than Gem alone or P3A5 + Gem. We converted these two antibodies to human:mouse chimeric forms: the constructed P3A5 and P1G4 chimeric mVLhCκ and mVHhCγ (γ1, γ2, γ4) genes were inserted in a single mammalian expression plasmid vector, and transfected into human 293F cells. Expressed human:mouse chimeric IgG1, IgG2 and IgG4 antibodies retained AGR2 binding. Increase in IgG yield by transfected cells could be obtained with serial transfection of vectors with different drug resistance. These chimeric antibodies, when incubated with human blood, effectively lysed eAGR2+ PC3 prostate cancer cells. We have, thus, produced humanized anti-AGR2 antibodies that, after further testing, might be suitable for treatment against a variety of eAGR2+ solid tumors.

Abstract
INTRODUCTION First-line treatment with platinum-based chemotherapy has been the standard treatment for non-small-cell lung cancer (NSCLC) during the past decades. The development of new targeted drugs based on molecular alterations (EGFR, ALK, and ROS1) has led to important outcome benefits, but not for squamous cell carcinoma (SCC). However, the aberrant function of the EGFR pathway in SCC may be important in the development of the tumor and has been explored in preclinical and clinical studies as a potential target. Areas covered: Necitumumab is a human IgG1 anti-EGFR antibody that binds to the receptor and inhibits further pathway activation, thereby inhibiting cell differentiation, proliferation and migration. The phase III SQUIRE trial was a randomized study of gemcitabine-cisplatin plus necitumumab versus gemcitabine-cisplatin alone for first-line stage IV squamous NSCLC, showing a higher overall survival and better disease control with the addition of necitumumab. Despite the good results, the lack of robust predictive biomarkers makes the selection of the patients who will benefit the most complex. Expert opinion: Necitumumab plus cisplatin-gemcitabine is a first-line treatment option in SCC that improves overall survival and preserves the patient's quality of life with a manageable toxicity profile.

Abstract
Homoharringtonine (HHT), an inhibitor of protein synthesis, has been used to treat leukemia. Its therapeutic effects on non-small cell lung adenocarcinoma carrying KRAS mutation and their immune system are less understood. The present study examined the therapeutic efficacy and the immune effects of HHT in two murine lung tumor models, xenograft and transgenic, carrying the Kras mutation G12D and G12C respectively. HHT exhibited efficient anticancer activity, significantly suppressing lung tumor growth in vitro and in vivo. The levels of 22 cytokines and chemokines in splenocytes of tumor-bearing mice were examined. Interleukin-12 expression was lower in splenocytes of HHT-treated mice when compared to the controls as demonstrated by a cytokine array and an enzyme-linked immunosorbent assay. The expression levels of CD80, CD86, and CD69 in B220+ B cells from splenocytes of HHT-treated mice were higher than that of control mice in two mouse tumor models. Furthermore, antitumor effect of HHT was attenuated with depletion of B cells. Increased numbers of CD80+ and CD86+ B cells were observed in the mice treated with narciclasine, another translation inhibitor. In conclusion, HHT changed the features of immune cells, and exhibited efficient anti-tumor activity against lung tumor carrying mutant Kras expression.

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 identification of common molecular aberrations that drive cancer progression has led to targeted therapies that improve treatment efficacy in many tumor types. Epidermal growth factor receptor (EGFR) inhibitors have been used to treat both lung and head and neck cancers with squamous cell histology. These tumors often show high EGFR expression and/or increased gene copy number, but low incidence of the activating kinase domain mutations common to adenocarcinomas of the lung. In this manuscript, we review clinical trial data on EGFR-inhibitors in the treatment of squamous cell carcinoma (SqCC) of the lung and head and neck (SCCHN), including both efficacy and biomarker analyses. Although some efficacy with use of EGFR inhibitors is observed, the level of benefit varies within and across tumor types, and the predictive capacity of high EGFR protein expression and/or gene amplification, if any, is limited. Due to the lack of candidate biomarkers that consistently predict response to EGFR-inhibitor therapy across treatment setting and class of agent in SqCC of the lung and SCCHN, we explore the biology, genomics and patterns of response to EGFR-inhibitors to inform identification of potential biomarkers, highlighting several key molecules that have shown promise in preclinical studies and clinical trials across multiple cancer sites.

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
Both acute myeloid leukemia and chronic myeloid leukemia are thought to arise from a subpopulation of primitive cells, termed leukemic stem cells that share properties with somatic stem cells. Leukemic stem cells are capable of continued self-renewal, and are resistant to conventional chemotherapy and are considered to be responsible for disease relapse. In recent years, improved understanding of the underlying mechanisms of myeloid leukemia biology has led to the development of novel and targeted therapies. This review focuses on clinically relevant patent applications and their relevance within the known literature in two areas of prevailing therapeutic interest, namely monoclonal antibody therapy and small molecule inhibitors in disease-relevant signaling pathways.

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.

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
PURPOSE OF REVIEW Important therapeutic advances for patients with advanced non-small-cell lung cancer (NSCLC) with focus on individualized therapy have recently occurred and are summarized in this review. RECENT FINDINGS Cetuximab added to first-line chemotherapy has been shown to improve survival in patients with high epidermal growth factor receptor (EGFR) expression in their tumors. Afatinib has shown improved progression-free survival and better quality of life compared to chemotherapy in patients with EGFR-mutation-positive adenocarcinomas. Several other EGFR-directed agents are in clinical development. Crizotinib improved progression-free survival compared to second-line chemotherapy with docetaxel or pemetrexed in patients with advanced anaplastic lymphoma kinase-positive NSCLC. Selumetinib added to docetaxel has improved outcome compared with docetaxel in a randomized phase II trial in patients with advanced KRAS-mutant NSCLC and this combination is currently studied in a phase III trial. Nintedanib added to docetaxel improved progression-free survival in the second-line therapy of patients with advanced NSCLC but many other angiogenesis inhibitors failed to improve clinical outcome in phase III trials. Several other targeted therapies are currently evaluated in phase III trials in patients with advanced NSCLC. SUMMARY Recent trials have led to the approval of afatinib and crizotinib for subsets of patients with advanced NSCLC.

Abstract
Background The purpose of this study was to evaluate the safety and efficacy of nimotuzumab in combination with chemotherapy (docetaxel and carboplatin) versus chemotherapy alone in patients with stage IIIB/IV non-small-cell lung cancer. Methods This multicenter, open-label, Phase II study randomized 110 patients to receive nimotuzumab plus chemotherapy (nimotuzumab group) or chemotherapy alone (control group), and comprised concomitant, maintenance, and follow-up phases. Nimotuzumab 200 mg was administered once weekly for 13 weeks during the first two phases with four cycles of chemotherapy and docetaxel 75 mg/m2 and carboplatin (area under the curve 5 mg/mL*min) every 3 weeks for a maximum of four cycles during the concomitant phase. The primary endpoint was objective response rate (sum of complete response and partial response). Secondary endpoints, ie, overall survival and progression-free survival, were estimated using the Kaplan–Meier method. Efficacy was evaluated on the intent-to-treat and efficacy-evaluable sets. Safety was assessed from adverse event and serious adverse event data. Results The objective response rate was significantly higher in the nimotuzumab group than in the control group in the intent-to-treat population (54% versus 34.5%; P=0.04). A complete response and partial response were achieved in 3.6% and 50% of patients, respectively, in the nimotuzumab group, and in 4% and 30.9% of patients, respectively, in the control group. No significant differences in median progression-free survival and overall survival were observed. Safety profiles were comparable between the two groups. Conclusion Nimotuzumab plus chemotherapy significantly improved the objective response rate as compared with chemotherapy alone. The combination was safe and well tolerated in patients with stage IIIB/IV non-small-cell lung cancer.

Abstract
The continuously rising use of novel drugs, especially of molecules belonging to the group of targeted drugs is now shaping the therapeutic landscape. However, treatment combinations of targeted drugs with radiotherapy are still rare. Only the monoclonal antibody cetuximab (Erbitux®) has been approved for the treatment of locally advanced squamous cell cancer of the head and neck in combination with radiotherapy. Several targeted compounds are in advanced stages of clinical development for combination treatments with radiotherapy, of which substances with either anti-EGFR or anti-angiogenic mechanisms, such as trastuzumab, panitumumab, erlotinib, cilengitide and bevacizumab are the most promising. Aim of this article is to provide, mainly from a radio-oncological point of view, an overview about the current state as well as to give an outlook on the near future of the most advanced targeted combined treatment concepts for solid tumors.

Abstract
AIM The aim of this analysis was to investigate the impact of tumour-, treatment- and patient-related cofactors on local control and survival after postoperative adjuvant radiotherapy in patients with non-small cell lung cancer (NSCLC), with special focus on waiting and overall treatment times. PATIENTS AND METHODS For 100 NSCLC patients who had received postoperative radiotherapy, overall, relapse-free and metastases-free survival was retrospectively analysed using Kaplan-Meier methods. The impact of tumour-, treatment- and patient-related cofactors on treatment outcome was evaluated in uni- and multivariate Cox regression analysis. RESULTS No statistically significant difference between the survival curves of the groups with a short versus a long time interval between surgery and radiotherapy could be shown in uni- or multivariate analysis. Multivariate analysis revealed a significant decrease in overall survival times for patients with prolonged overall radiotherapy treatment times exceeding 42 days (16 vs. 36 months) and for patients with radiation-induced pneumonitis (8 vs. 29 months). CONCLUSION Radiation-induced pneumonitis and prolonged radiation treatment times significantly reduced overall survival after adjuvant radiotherapy in NSCLC patients. The negative impact of a longer radiotherapy treatment time could be shown for the first time in an adjuvant setting. The hypothesis of a negative impact of longer waiting times prior to commencement of adjuvant radiotherapy could not be confirmed.

Abstract
Molecular imaging is a novel field in gastroenterology that uses fluorescently labelled probes to specifically highlight neoplastic lesions on the basis of their molecular signature. The development of molecular imaging has been driven by the need to improve endoscopic diagnosis and by progress in targeted therapies in gastrointestinal oncology to provide individualized treatment, which coincides with progress in endoscopy techniques and further miniaturization of detection devices. Different exogenous molecular probes for imaging include labelled antibodies, oligopeptides, affibodies(™) (Affibody AB, Bromma, Sweden), aptamers and activatable probes. Molecular imaging has been evaluated in two major indications: many trials have studied molecular imaging as a red flag technique to improve detection of lesions in wide-field imaging; on the other hand, microscopic analysis has been investigated for in vivo characterization of the molecular fingerprint of tumours with the ultimate goal of assessing the likelihood of response to targeted therapy. This Review focusses on the applications of molecular imaging that have immediate potential for translational science or imminent transition into clinical practice of gastrointestinal endoscopy.

Abstract
Lung cancer is one of the leading causes of death in industrialized and developing countries. Approximately 80% of patients are diagnosed with non-small cell histology. Although a multidisciplinary approach is necessary for the treatment of patients at early or locally-advanced stages of the disease, further successes in the treatment of patients with advanced disease will largely rely on improved systemic tumor control. Although therapies directed against the epidermal growth factor receptor (EGFR) have been incorporated into daily clinical practice, the value of other treatments remains to be elucidated. The current review highlights the most important driver mutations in non-small cell lung cancer (NSCLC) and describes recent study results and the status of EGFR-directed therapy, anaplastic lymphoma kinase (ALK)-directed agents, antiangiogenic therapy, and mesenchymal-epithelial transition factor (MET) inhibitors. However, many other agents with different modes of action are being examined in clinical research.

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
INTRODUCTION Lung cancer is the leading cause of cancer death worldwide. As clinical benefits to conventional cancer therapies are still formidable, there is an urgent need for novel agents and approaches to improve the overall clinical outcomes for patients with lung cancer. AREAS COVERED This article reviews the current understanding of targeted therapy for lung cancer with monoclonal antibodies (mAbs), mainly bevacizumab and cetuximab. The results from several key clinical trials validating the effectiveness and safety of bevacizumab and cetuximab, the relation of cancer biomarkers, the polymorphic correlation of targeted genes with the therapeutic outcome of mAb-based treatment, as well as the impact of Biomarker-integrated Approaches of Targeted Therapy for Lung Cancer Elimination (BATTLE) trial on personalised treatment of lung cancer are discussed. EXPERT OPINION The addition of bevacizumab or cetuximab to chemotherapy has shown promising benefits to the patients with non-small-cell lung cancer. However, the overall benefits of mAb-based targeted therapy to lung cancer patients vary among individuals. It is therefore necessary to define reliable predictive biomarkers in an effort to better identify patients who are most likely to benefit from treatment with these novel agents in lung cancer.

Abstract
SUMMARY Metastatic non-small-cell lung cancer (NSCLC) is one of the most incident cancers for which no curative therapies exist. New insights into the genetic background of the disease have led to the development of new effective therapies, including monoclonal antibodies. Bevacizumab demonstrated improved response rate and progression-free survival in two Phase III trials in association with conventional chemotherapy as first-line treatment for metastatic NSCLC. Cetuximab has proved to be effective in patients with advanced NSCLC expressing EGFR by immunohistochemistry. One of the promising targets in NSCLC is the MET pathway, for which monoclonal antibodies are under development. This review aims to describe the role of monoclonal antibodies for advanced NSCLC and future perspectives in this field.

Abstract
This review offers an overview of the molecular pathology of lung cancer, with a focus on analyses that are most commonly part of the current clinical testing paradigm. Molecular testing of lung cancer has proved integral to the success of new targeted therapies, and their use is now commonplace in treatment selection. Traditional pathologic evaluation, however, plays a major role in these advances and serves an equally critical role to aid in determining optimal therapy.

Abstract
Lung cancer is in France, the leading cause of cancer death. Despite the dramatic advances that have allowed in a few years to go, for metastatic cancer, from a median survival without specific treatment of 4.5 months and now almost always more than one year, survival remains disappointing and further improvements are needed. Progress in the accumulated knowledge of the inner workings of normal and tumoral cells have paved the way for the development of targeted therapeutics called biological or simply targeted therapies. Two biological processes are already the target of marketed drugs, this is the way the receptor of epidermal growth factor (EGFR) and the path of neo-angiogenesis. It is almost assumed that, in the very near future, the inhibition of EML4-ALK will also be the subject of new drugs. In the medium term, it is conceivable that the molecular dissection of the tumors actually lead to the prescription of treatments tailored to mutations and other abnormalities that direct the growth of cancers.

Abstract
Until recently, the division of pulmonary carcinomas into small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) was adequate for therapy selection. Due to the emergence of new treatment options subtyping of NSCLC and predictive testing have become mandatory. A practical approach to the new requirements involving interaction between pulmonologist, oncologist and molecular pathology to optimize patient care is described. The diagnosis of lung cancer involves (i) the identification and complete classification of malignancy, (ii) immunohistochemistry is used to predict the likely NSCLC subtype (squamous cell vs. adenocarcinoma), as in small diagnostic samples specific subtyping is frequently on morphological grounds alone not feasible (NSCLC-NOS), (iii) molecular testing. To allow the extended diagnostic and predictive examination (i) tissue sampling should be maximized whenever feasible and deemed clinically safe, reducing the need for re-biopsy for additional studies and (ii) tissue handling, processing and sectioning should be optimized. Complex diagnostic algorithms are emerging, which will require close dialogue and understanding between pulmonologists and others who are closely involved in tissue acquisition, pathologists and oncologists who will ultimately, with the patient, make treatment decisions. Personalized medicine not only means the choice of treatment tailored to the individual patient, but also reflects the need to consider how investigative and diagnostic strategies must also be planned according to individual tumour characteristics.
