    Thoracoscopic surgery can be one of less invasive surgical interventions for early stage lung cancer. Locally advanced lung cancer, however, cannot avoid aggressive procedures including pneumonectomy and/or extended combined resection of chest wall, aorta, esophagus, etc. for complete resection. Surgical approach even for advanced lung cancer can be less invasive by benefit from new anti-cancer treatment, innovated manipulations of bronchoplasty and angioplasty, and bench surgery( lung autotransplantation technique). We herein reviewed the strategy to minimize invasive interventions for locally advanced lung cancer, introducing 2 successful cases with advanced lung cancer. The 1st patient is a 62-year old man with centrally advanced lung cancer invading to mediastinum. Right upper sleeve lobectomy with one-stoma carinoplasty following induction chemoradiation therapy was successful. The operation time was 241 minutes. The performance status is good with no recurrence for 60 months after surgery. The 2nd is a 79-year old man with advanced lung cancer invading to the distal aortic arch. Left upper segmentectomy following thoracic endovascular aortic repair with stentgraft was successful with no extracorporeal circulation. The operation time was 170 minutes. The performance status is good with no recurrence for 30 months after surgery. The invasiveness of surgical interventions for local advanced lung cancer can be minimized by innovated device and new anti-cancer drugs. PMID:27440037

    Lung cancer is the most commonly diagnosed cancer as well as the leading cause of cancer-related deaths worldwide. To date, surgery is the first choice treatment, but most clinically diagnosed cases are inoperable. While chemotherapy and/or radiotherapy are the next considered options for such cases, these treatment modalities have adverse effects and are sometimes lethal to patients. Thus, new effective strategies with minimal side effects are urgently needed. Cancer immunotherapy provides either active or passive immunity to target tumors. Multiple immunotherapy agents have been proposed and tested for potential therapeutic benefit against lung cancer, and some pose fewer side effects as compared to conventional chemotherapy and radiotherapy. In this article, we discuss studies focusing on interactions between lung cancer and the immune system, and we place an emphasis on outcome evidence in order to create a knowledge base well-grounded in clinical reality. Overall, this review highlights the need for new lung cancer treatment options, with much ground to be paved for future advances in the field. We believe that immunotherapy agents alone or with other forms of treatment can be recognized as next modality of lung cancer treatment. PMID:27168951

    Full Text Available Lung cancer is one of the malignant tumors with fastest growing rates in incidence and mortality in our country, also with largest threat to human health and life. However, the exact mechanisms underlying lung cancer development remain unclear. The microenvironment of tumor hypoxia was discovered in 1955, but hypoxia in lung cancer tissues had not been successfully detected till 2006. Further studies show that hypoxia not only functions through the resistance to radiotherapy, but also regulates lung cancer development, invasion, metastasis, chemotherapy resistance and prognosis through an important oncogene HIF (hypoxia inducible factor, with its regulators PHD (prolyl hydroxylase domain and pVHL (product of von Hippel-Lindau gene. Therefore, hypoxia, HIF, PHD and pVHL should be considered as potential therapeutic targets for lung cancer pathogenesis and progression.

    Full Text Available Cancer stem cells (CSCs are emerging as a hot topic for cancer research. Lung CSCs share many characteristics with normal lung stem cells (SCs, including self-renewal and multi-potency for differentiation. Many molecular markers expressed in various types of CSCs were also found in lung CSCs, such as CD133, CD44, aldehyde dehydrogenase (ALDH and ATP-binding cassette sub-family G member 2 (ABCG2. Similarly, proliferation and expansion of lung CSCs are regulated not only by signal transduction pathways functioning in normal lung SCs, such as Notch, Hedgehog and Wnt pathways, but also by those acting in tumor cells, such as epidermal growth factor receptor (EGFR, signal transducer and activator of transcription 3 (STAT3 and phosphatidylinositol 3 kinase (PI3K pathways. As CSC plays an critical role in tumor recurrence, metastasis and drug-resistance, understanding the difference between lung CSCs and normal lung SCs, identifying and targeting CSC markers or related signaling pathways may increase the efficacy of therapy on lung cancer and improved survival of lung cancer patients.

    Full Text Available Background and objective Lung cancer is the leading cause of cancer-related deaths worldwide. Next to adenocarcinoma, squamous cell carcinoma (SCC of the lung is the most frequent histologic subtype in non-small cell lung cancer. Several molecular alterations have been defined as "driver oncogenes" responsible for both the initiation and maintenance of the malignancy. The squamous cell carcinoma of the lung has recently shown peculiar molecular characteristics which relate with both carcinogenesis and response to targeted drugs. So far, about 40% of lung squamous cell carcinoma has been found harbouring driver oncogenes, in which fibroblast growth factor receptor 1 (FGFR1 plays important roles. In this review, we will report the mainly advances on some latest driver mutations of squamous cell lung cancer.

    In most patients, lung cancer presents as advanced disease with metastases to lymph nodes and/or distant organs, and survival is poor. Lung cancer is also a highly immune-suppressing malignancy with numerous methods to evade antitumor immune responses, including deficiencies in antigen processing and presentation, release of immunomodulatory cytokines, and inhibition of T-cell activation. Advances in understanding the complex interactions of the immune system and cancer have led to novel therapies that promote T-cell activation at the tumor site, resulting in prolonged clinical benefit. Immune checkpoint inhibitors, specifically programmed death receptor 1 pathway antibodies, have demonstrated impressively durable responses and improved survival in patients with non-small cell lung cancer. This article will review the recent progress made in immunotherapy for lung cancer with data from trials evaluating programmed death receptor 1 and cytotoxic T-lymphocyte-associated protein 4 monoclonal antibodies in addition to cancer vaccines. The review will focus on studies that have been published and the latest randomized trials exploring immune therapy in lung cancer. These results form the framework for a new direction in the treatment of lung cancer toward immunotherapy. PMID:27058851

    Maintenance therapy is a new treatment strategy for advanced non-small-cell lung cancer(NSCLC), and it consists of switch maintenance and continuation maintenance.Switch maintenance is the introduction of a different drug, not included as part of the induction therapy, immediately after completion of 4 cycles of first-line platinum-based chemotherapy.Continuation maintenance is a continuation of at least one of the drugs used in the induction therapy in the absence of disease progression.Several phase III trials have reported survival benefits with continuation maintenance of pemetrexed and switch maintenance of pemetrexed or erlotinib.Therefore, maintenance therapy has become a part of the standard first-line treatment for advanced NSCLC.However, further research is needed to elucidate the selection criteria of patients who may benefit the most from maintenance therapy.

  1. Clinical experience of intrapleural administration of fibrin glue for secondary pneumothorax with advanced lung cancer

    International Nuclear Information System (INIS)

    Secondary pneumothorax with advanced lung cancer is an intractable and serious pathosis, which directly aggravates patients' Quality of Life (QOL) and prognosis. We first select the intrapleural administration of fibrin glue for secondary pneumothorax with advanced lung cancer. From April 2009 to May 2012, we encountered 5 patients who developed secondary pneumothorax during treatment for advanced lung cancer. Their average age was 60.8 years old, and 4 of them had squamous cell carcinoma, 1 had adenocarcinoma, and all had unresectable advanced lung cancer. In 4 of them, the point of air leakage could be detected by pleurography, and leakage could be stopped by the intrapleural administration of fibrin glue. All of them could receive chemotherapy or radiotherapy after treatment for secondary pneumothorax. The intrapleural administration of fibrin glue may be an effective and valid treatment for intractable secondary pneumothorax with advanced lung cancer. (author)

    In the last 10-15 years, strategies and modalities of lung cancer treatment have changed dramatically. Meanwhile, the treatment objectives, the lung cancers themselves, have also changed, probably owing to early detection by computed tomography and aging of the population. In particular, the proportions of smaller lung cancers, lung adenocarcinomas with ground-glass opacity, and lung cancers in older patients are increasing. Along with these changes, surgeons have innovated and evaluated novel procedures for pulmonary resection. These include the application of minimally invasive surgical techniques, such as video-assisted thoracoscopic surgery (VATS) and robotic surgery, and sub-lobar resection, such as wedge resection and segmentectomy, for small peripheral lung cancers. Currently, VATS has gained wide acceptance and several institutions in Japan have started using robotic surgery for lung cancers. Two important clinical trials of sub-lobar resection for small peripheral lung cancers are now underway in Japan. In addition, surgery itself is of growing importance in lung cancer treatment. In particular, recent evidence supports the use of surgery in strictly selected patients with locally advanced disease, lung cancers with N2 lymph node metastases, small cell lung cancers, recurrent oligo-metastasis after pulmonary resection, or relapsed tumors after drug treatment. Surgical treatment also provides abundant tumor samples for molecular analysis, which can be used for drug selection in the adjuvant setting or after disease relapse. In the era of personalized treatment, surgery is still one of the most important treatment modalities to combat lung cancer. PMID:25453375

    Full Text Available Lung cancer is the malignant disease with the highest rate in terms of incidence and mortality in China. Early diagnosis and timely monitoring tumor recurrence and metastasis are extremely important for improving 5-year survival rate of lung cancer patients. Circulating tumor cells (CTCs, as a "liquid biopsy specimens” for the primary tumor, provide the possibility to perform real-time, non-invasive histological identification for lung cancer patients. The detection of CTCs contributes to early diagnosis, surveillance of tumor recurrence and metastasis, and prediction of therapeutic efficacy and prognosis. Furthermore, CTCs-dependent detection emerges as a new approach for molecularly pathologic examination, study of molecular mechanisms involved in drug resistance, and resolution for tumor heterogeneity. This study reviewed the recent progress of CTCs in lung cancer research field.

    Full Text Available Non-small cell lung cancer is the most common pathological type of lung cancer. Along with the rising incidence in recent years, lung cancer has been the leading cause of death due to malignancies both in our country and worldwide. Due to simplistic therapeutic approach for lung cancer decades ago, those patients suffering from advanced lung cancer had short lifetime, and it was difficult to ensure their life quality. In recent years, many molecular targeted drugs, such as Gefitinib, Erlotinib and Crizotinib etc., have been successively applied in clinical use, and they bring about a substantial prolongation of survival life and improvement in life quality of those patients with advanced lung cancer. In 2014, there was a number of important reports concerning the diagnosis and treatment of non-small cell lung cancer in the annual meetings of either American Society of Clinical Oncology or European Society for Medical Oncology. On the basis of the relevant reports delivered in the conferences, it is our attempt to summarize the recent advances in regard to chemotherapy, molecular targeted therapy, measures to treat TKI therapy resistant cases, and immune therapy, followed by a comment regarding recent advances in the treatment of non-small cell lung cancer in 2014.

    Different approaches for treating lung cancer have been developed over time, including chemotherapy, radiotherapy and targeted therapies against activating mutations. Lately, better understanding of the role of the immunological system in tumor control has opened multiple doors to implement different strategies to enhance immune response against cancer cells. It is known that tumor cells elude immune response by several mechanisms. The development of monoclonal antibodies against the checkpoint inhibitor programmed cell death protein 1 (PD-1) and its ligand (PD-L1), on T cells, has led to high activity in cancer patients with long lasting responses. Nivolumab, an anti PD-1 inhibitor, has been recently approved for the treatment of squamous cell lung cancer patients, given the survival advantage demonstrated in a phase III trial. Pembrolizumab, another anti PD-1 antibody, has received FDA breakthrough therapy designation for treatment of non-small cell lung cancer (NSCLC), supported by data from a phase I trial. Clinical trials with anti PD-1/PD-L1 antibodies in NSCLC have demonstrated very good tolerability and activity, with response rates around 20% and a median duration of response of 18 months.

    Lung cancer has a poor prognosis; over half of people diagnosed with lung cancer die within one year of diagnosis and the 5-year survival is less than 18%. Non-small cell lung cancer (NSCLC) accounts for the majority of all lung cancer cases. Risk factors for developing NSCLC have been identified, with cigarette smoking being a major factor along with other environmental and genetic risk factors. Depending on the staging of lung cancer, patients are eligible for certain treatments ranging from surgery to radiation to chemotherapy as well as targeted therapy. With the advancement of genetics and biomarkers testing, specific mutations have been identified to better target treatment for individual patients. This review discusses current treatments including surgery, chemotherapy, radiotherapy, and immunotherapy as well as how biomarker testing has helped improve survival in patients with NSCLC.

    Full Text Available Small cell lung cancer (SCLC is complex heterogeneous due to unclear biological characteristics in terms of cell origin, pathogenesis and driver genes etc. Diagnosis and treatment of SCLC has been slowly improved and few breakthroughs have been discovered up to now. Therefore new strategies are urgently needed to improve the efficacy of SCLC treatment. Tumor immunotherapy has potential to restore and trigger the immune system to recognize and eliminate tumor cells, notably it has only minimal adverse impact on normal tissue. Cancer vaccine, adoptive immunotherapy, cytokines and checkpoint inhibitors have now been launched for clinical treatment of SCLC. Ipilimumab is the most promising medicine of immunotherapy. Immunotherapy is expected to bring new vision to the treatment of SCLC. And further researches are needed on such problems affecting efficacy of immunotherapy as the heterogeneity of SCLC, the uncertainty of target for immunotherapy, the immune tolerance, etc.

    Full Text Available Data supporting use of concurrent chemoradiation in locally advanced lung cancers comes from clinical trials from developed countries. Applicability and outcomes of such schedules in developing countries is not widely reported. There are various challenges in delivering chemoradiation in locally advanced non small cell lung cancer in developing countries which is highlighted by an audit of patients treated with chemoradiation in our center. This article deals with the challenges in the context of a developing country. We conclude that sequential chemoradiotherapy is better tolerated than concurrent chemoradiation in Indian patients with locally advanced non-small cell lung cancers. Patients with stage IIIa, normal weight or overweight, and adequate baseline pulmonary function should be offered concurrent chemoradiation.

    Full Text Available Background: Spinal metastases of patients with advanced stage lung cancer are an important target for palliative therapy, because their incidence is high, and they often cause severe symptoms and worsen the quality of life. Surgery is one of the most effective treatment options, but the indication of surgery is unclear as the procedure is invasive and patients with spinal metastasis have a rather short life expectancy. Furthermore, there have been few studies that have focused on lung cancer with poor prognosis. Methods: We reviewed all of the cases of lung cancer from January 1999 to July 2007 in the Department of Respiratory Medicine, Kyoto University Hospital, Japan. Thirteen patients with metastatic spinal tumor of lung cancer underwent surgery, and all of them had a poor performance status score (3 or 4. Results: Neurological improvement by at least 1 Frankel grade was seen in 10 of 14 cases (71%. Improvement of the movement capacity was noted in 9 of 14 cases (64%, and pain improvement was noted in 12 of 14 (86%. Median postoperative survival was 5 months (1–25 months. In particular, the group with a good postoperative performance status score (0–2 was shown to have a better median postoperative survival of 13 months. Conclusions: Surgical treatment for symptomatic metastatic spinal tumor of lung cancer can improve quality of life in a substantially high percentage of patients. Surgery should be considered even if preoperative performance status is poor.

    Full Text Available Background: For inoperable non-small cell lung cancer combined chemotherapy and radiotherapy plays an important role as a therapeutic modality. The aim of the present study was to analyze neoadjuvant chemotherapy related acute toxicity in locally advanced lung cancer (stage IIIA and IIIB in Indian patients using Cisplatin and Etoposide combination chemotherapy. Material and methods: Forty patients of locally advanced Non small cell lung cancer received three cycles neoadjuvant chemotherapy using Injection Cisplatin and Etoposide. The patients were taken for Radical radiotherapy to a dose of 60 Gray over 30 fractions in conventional fractionation after completing chemotherapy. Chemotherapy associated toxicity was assessed using common toxicity criteria (CTC v2.0 Results: Forty patients were available for final evaluation. Median age of presentation of patients was fifty-six years. Thirteen patients had Non small cell lung cancer stage IIIA while twenty-seven patients had Stage IIIB disease. Anemia was the most common hematological toxicity observed (seen in 81% of patients. Nausea and vomiting were the most common non -hematological toxicity seen. Sensory neuropathy was seen in 38%of patients. 88% patients developed alopecia. Seven patients developed febrile neutropenias. Conclusion: Neo-adjuvant chemotherapy using Cisplatin and Etoposide continues to be a basic regimen in the Indian set up despite availability of higher molecules, since it is cost effective, well tolerated and therapeutically effective. Blood transfusions, growth factors and supportive care can be used effectively to over come toxicity associated with this regimen.

  9. SU-E-J-87: Ventilation Weighting Effect On Mean Doses of Both Side Lungs for Patients with Advanced Stage Lung Cancer

    International Nuclear Information System (INIS)

    Purpose: To study ventilation weighting effect on radiation doses to both side lungs for patients with advanced stage lung cancer. Methods: Fourteen patients with advanced stage lung cancer were included in this retrospective study. Proprietary software was developed to calculate the lung ventilation map based on 4DCT images acquired for radiation therapy. Two phases of inhale (0%) and exhale (50%) were used for the lung ventilation calculations. For each patient, the CT images were resampled to the same dose calculation resolution of 3mmx3mmx3mm. The ventilation distribution was then normalized by the mean value of the ventilation. The ventilation weighted dose was calculated by applying linearly weighted ventilation to the dose of each pixel. The lung contours were automatically delineated from patient CT image with lung window, excluding the tumor and high density tissues. For contralateral and ipsilateral lungs, the mean lung doses from the original plan and ventilation weighted mean lung doses were compared using two tail t-Test. Results: The average of mean dose was 6.1 ±3.8Gy for the contralateral lungs, and 26.2 ± 14.0Gy for the ipsilateral lungs. The average of ventilation weighted dose was 6.3± 3.8Gy for the contralateral lungs and 24.6 ± 13.1Gy for the ipsilateral lungs. The statistics analysis shows the significance of the mean dose increase (p<0.015) for the contralateral lungs and decrease (p<0.005) for the ipsilateral lungs. Conclusion: Ventilation weighted doses were greater than the un-weighted doses for contralateral lungs and smaller for ipsilateral lungs. This Result may be helpful to understand the radiation dosimetric effect on the lung function and provide planning guidance for patients with advance stage lung cancer

    The intensity of complains, short survival and great number of patients makes many oncologists to apply chemotherapy in advanced non-small cell lung cancer/NSCLC/. The achieved median duration of life after chemotherapy was 6 to 12 month. From the other hand non small cell lung cancer chemotherapy is a big burden even to healthy persons. It can worsen the quality of life. That was the reason we evaluated the quality of life after chemotherapy in advanced non small cell lung cancer patients. Taking into account, that the evaluation of quality of life, used in most diseases is useless in advanced NSCLC patients, for appreciation the quality of life in these cases the lung cancer symptoms scale/LCSS/was adopted. In 110 non small cell lung cancer patients in stage IIIB and IV, who received combined chemotherapy by Le Chevalier/Vindesine, Cisplatin, Cyclophosphamide, Lomustin/or by Rosell/Mitomycin, Cyclophosphamide, Cisplatin/the quality of life was evaluated. In 20-persons control group all patients received the symptomatic treatment. In observed group of 110 patients, tumor regressions after 4 courses of chemotherapy allowed to resect cancer in 14 cases, to apply radiotherapy in 42 and to continue chemiotherapy in 23 persons. In every person from above mentioned group the quality of life was evaluated on the basis of intensity of cancer symptoms, accordingly to LCSS. The intensity of cancer symptoms was compared before and after treatment. There were compared; the innensity of complains, weakness, appetite, malnutrition, and hematological, neurological, performans state as well as respiratory sufficiency, infections, cardiac disorders and pain. Apart it, the side effects of applied therapy were assessed in 5 degree scale. The level of hemoglobin, the number of leucocytes, thrombocytes, bilirubine and transaminases in peripheral blood, hematurie, proteinurie, bleedings, appetite, nausea, vomitings, diarrhea, mucosal lesions, infections, skin lesions, cardiac lesions

    This study explores expressed wishes and requests for euthanasia (i.e. administration of lethal drugs at the explicit request of the patient), and incidence of end-of-life decisions with possible life-shortening effects (ELDs) in advanced lung cancer patients in Flanders, Belgium. We performed a prospective, longitudinal, observational study of a consecutive sample of advanced lung cancer patients and selected those who died within 18 months of diagnosis. Immediately after death, the pulmonologist/oncologist and general practitioner (GP) of the patient filled in a questionnaire. Information was available for 105 out of 115 deaths. According to the specialist or GP, one in five patients had expressed a wish for euthanasia; and three in four of these had made an explicit and repeated request. One in two of these received euthanasia. Of the patients who had expressed a wish for euthanasia but had not made an explicit and repeated request, none received euthanasia. Patients with a palliative treatment goal at inclusion were more likely to receive euthanasia. Death was preceded by an ELD in 62.9% of patients. To conclude, advanced lung cancer patients who expressed a euthanasia wish were often determined. Euthanasia was performed significantly more among patients whose treatment goal after diagnosis was exclusively palliative.

    Because of increasing life expectancy and of higher risk of cancer with ageing, lung cancer in elderly is a frequent disease. For a long time nihilism influenced treatment decisions in elderly patients with advanced non-small cell lung cancer. Since the beginning of the last decade single agent chemotherapy has been accepted as standard of care, vinorelbine and gemcitabine being the most frequently used drugs in Europe and US, docetaxel in Japan. Platinum-based doublets have been shown to be superior to monotherapy in young and fit patients with advanced non-small cell lung cancer. Although there were some indications from subgroup analyses of clinical trials not specifically dedicated to elderly patients that a platinum-based doublet might also benefit to older patients, there was no definitive proof of concept until ASCO meeting 2010. At this meeting results of a phase 3 trial showed that PS 0-2 patients, aged 70-89 years drove a significant benefit from a treatment with carboplatin associated to weekly paclitaxel compared to a monotherapy. Thus, the paradigm of treatment in elderly patients should perhaps be modified from a single agent to doublet chemotherapy. Whether other platinum-based doublets would provide the same benefit as the specific one studied remains to be evaluated. PMID:21893363

    Full Text Available Abstract Introduction Lung cancer is now considered the most common cause of death among cancer patients. Although target biological regimens have emerged in recent years for non-small cell lung carcinoma, the survival and quality of life of patients with this condition still remain low. The five-year survival rate for all stages of lung cancer is 17% or less. Case presentation We describe the case of a 53-year-old Caucasian woman who was diagnosed with advanced stage IIIa (T2aN2M0 non-small cell lung carcinoma (adenocarcinoma and underwent a complete left upper lobectomy three years ago. After two and a half years of follow-up, she suddenly presented with facial edema and venous distension and was immediately treated for superior vena cava syndrome. Because of a diagnostic check, a major clot was detected in the right subclavian vein. Our patient was informed about treatment options, and she was taken to the catheterization laboratory for percutaneous stenting of the superior vena cava to restore superior vena cava patency. Conclusion Lung cancer has a vast number of complications. Superior vena cava syndrome and thrombosis should be considered upon the presentation of a patient with obstructive symptoms. In this case report, even though we expected the clot to be on the side of the former lesion, it was present on the opposite side. Treatment should also start immediately in these patients with clinical suspicion of thrombosis to avoid further complications, even in cases with a differential diagnosis problem. Finally, although patients with non-small cell lung carcinoma have a high incidence of thromboembolic events, anticoagulant treatment is given only as maintenance therapy after a first event occurs.

    Despite advances in the detection, pathological diagnosis and therapeutics of lung cancer, many patients still develop advanced, incurable and progressively fatal disease. As physicians, the duties to cure sometimes, relieve often and comfort always should be a constant reminder to us of the needs that must be met when caring for a patient with lung cancer. Four key areas of end-of-life care in advanced lung cancer begin with first recognizing 'when a patient is approaching the end of life'. The clinician should be able to recognize when the focus of care needs to shift from an aggressive life-sustaining approach to an approach that helps prepare and support a patient and family members through a period of progressive, inevitable decline. Once the needs are recognized, the second key area is appropriate communication, where the clinician should assist patients and family members in understanding where they are in the disease trajectory and what to expect. This involves developing rapport, breaking bad news, managing expectations and navigating care plans. Subsequently, the third key area is symptom management that focuses on the goals to first and foremost provide comfort and dignity. Symptoms that are common towards the end of life in lung cancer include pain, dyspnoea, delirium and respiratory secretions. Such symptoms need to be anticipated and addressed promptly with appropriate medications and explanations to the patient and family. Lastly, in order for physicians to provide quality end-of-life care, it is necessary to understand the ethical principles applied to end-of-life-care interventions. Misconceptions about euthanasia versus withholding or withdrawing life-sustaining treatments may lead to physician distress and inappropriate decision making. PMID:27585597

  18. Impact of group psychotherapy in chemotherapy induced vomiting for treatment of advanced breast and lungs cancer

    International Nuclear Information System (INIS)

    To assess the effect of group psychotherapy in the management of the side effects of chemotherapy treatment in advanced breast and lung cancer. One hundred patients treated with chemotherapy for advanced stage (IIIB and IV) breast and lung cancer were selected with ECOG performance status of 0 or 1. All patients received anti-emetic medications half an hour before chemotherapy. All those patients in this category who completed fist line chemotherapy with 6 cycles were included. Fifty were subjected to group discussions with other patients, family members and medical staff. This was labeled group A. The other 50 were not included in group discussion and were labeled group B. Both the group received similar standard chemotherapy and pre-medication for vomiting as per their disease and chemotherapy schedule. Breast and lung cancer patients were 29 and 21 in each arm respectively. At the end of the discharge, grade 2 and above of vomiting, according to common terminology criteria for adverse events (CTCAE) was counted for all patients in both the arms A and B, over full length of treatment for 6 cycles, and then were compared statistically. Mean with standard deviation for adverse event (vomiting) in group A and B was 6.2 + 2.6 and 13.4 + 3.8 respectively per cycle of treatment. It was observed that group psychotherapy had statistically significant effect (p-value <0.05) on the management of vomiting. Group psychotherapy can be used to reduce the incidence of vomiting in advanced breast and lung cancer patients treated with chemotherapy. (author)

These differences appear to have a direct impact on the clinical presentation, histology, and outcomes of lung cancer. Women are more likely to present with lung adenocarcinoma, tend to receive a diagnosis at an earlier age, and are more likely to be diagnosed with localized disease. Women may also be more predisposed to molecular aberrations resulting from the carcinogenic effects of tobacco, but do not appear to be more susceptible than men to developing lung cancer. The gender differences found in female lung cancer make it mandatory that gender stratification is used in clinical trials in order to improve the survival rates of patients with lung cancer.Keywords: lung cancer, adenocarcinoma, women, genetic susceptibility, genetic differences, tobacco

    Lung cancer is the leading cause of death cancer related worldwide. The standard therapies have unmet medical needs both due to the limited activity and relevant toxicity of platinum-based chemotherapy and to the low frequency of specific alterations required to use targeted therapies. Immune checkpoint inhibition due to restoring the immune system's capacity to eradicate tumors is undergoing in extensive investigation in non-small cell lung cancer (NSCLC) as a new treatment approach. Programmed cell death protein-1 (PD-1) and its ligand, programmed cell death-ligand 1 (PD-L1) have recently led to significantly and durable improvements in the clinical outcome of several kind of tumors including lung cancer. Pembrolizumab, approved by the U.S. FDA for the treatment of advanced NSCLC progressed after other therapies and with expression of PD-L1, has demonstrated durable response and prolonged overall survival (OS) especially in patients with high PD-L1 expression. Further investigation are needed to improve treatment outcomes through combination of immunotherapy or combined with other targeted therapies.

    Full Text Available Lung cancer remains a major cause of cancer-related lethality because of high incidence and recurrence in spite of significant advances in staging and therapies. Recent data indicates that stem cells situated throughout the airways may initiate cancer formation. These putative stem cells maintain protumorigenic characteristics including high proliferative capacity, multipotent differentiation, drug resistance and long lifespan relative to other cells. Stem cell signaling and differentiation pathways are maintained within distinct cancer types, and destabilization of this machinery may participate in maintenance of cancer stem cells. Characterization of lung cancer stem cells is an area of active research and is critical for developing novel therapies. This review summarizes the current knowledge on stem cell signaling pathways and cell markers used to identify the lung cancer stem cells.

    Full Text Available Beckground/Aim. Neuroendrocine lung tumors are histologically heterogenous group of cancers with different clinical progression. In non-small cell lung cancer (NSCLC neuroendocrine differentiation exists in 10-30% of patients. The aim of this study was to determine the frequency and influence of neuroendocrine differentiation on survival of treated patients with advanced non-small cell lung cancer (NSCLC. Methods. A clinical trial included 158 patients (74% males and 26% females, with the diagnosis of NSCLC, determined by histological verification. The patients were treated by combined chemo - and X-ray therapy in stage III (without pleural effusion or chemotherapy only in stage III (with pleural effusion and stage IV. Chemotherapy was conducted until progression of the disease, but no more than six cycles. When the progression had been noted in stage III (without pleural effusion, the treatment was continued with X-ray therapy. Neuron specific enolase, chromogranin A, as well as synapthophysin expression in tissue examples were determined by immunohistochemical analysis with monoclonal mouse anti-human-bodies. Survival was assessed within a year and two years follow-up examination. Results. A total of 53 patients (34% had NSCLC with neuroendocrine differentiation, confirmed rather in large cell lung cancer and lung adenocarcinoma (66.7% and 40%, respectively. Neuron specific enolase, chromogranin A and synapthophysin expression was noted in 45 (28.5%, 34 (21.5% and 33 (20.1% patients, respectively. The one year and two years follow-up survival periods were confirmed in 39% and 17% of patients respectively. The median survival time in the patients with the neuroendocrine expression as compared to those without the expression was 15.6 vs 10.8 months; one year survival time with the expression compared to those without the expression achieved in 62% vs 27% of the patients, (p < 0.001; a two - year survival time noted in 30% of the patients (p = 0

    Full Text Available BACKGROUND: Circulating endothelial cells and microparticles have prognostic value in cancer, and might be predictors of response to chemotherapy and antiangiogenic treatments. We have investigated the prognostic value of circulating endothelial cells and microparticles in patients treated for advanced non-small cell lung cancer. METHODOLOGY/PRINCIPAL FINDINGS: Peripheral blood samples were obtained from 60 patients before first line, platinum-based chemotherapy +/- bevacizumab, and after the third cycle of treatment. Blood samples from 60 healthy volunteers were also obtained as controls. Circulating endothelial cells were measured by an immunomagnetic technique and immunofluorescence microscopy. Phosphatidylserine-positive microparticles were evaluated by flow cytometry. Microparticle-mediated procoagulant activity was measured by the endogen thrombin generation assay. RESULTS: pre- and posttreatment levels of markers were higher in patients than in controls (p<0.0001. Elevated levels of microparticles were associated with longer survival. Elevated pretreatment levels of circulating endothelial cells were associated with shorter survival. CONCLUSIONS/SIGNIFICANCE: Circulating levels of microparticles and circulating endothelial cells correlate with prognosis, and could be useful as prognostic markers in patients with advanced non-small cell lung cancer.

    Lung cancer remains a major cause of cancer-related lethality because of high incidence and recurrence in spite of significant advances in staging and therapies. Recent data indicates that stem cells situated throughout the airways may initiate cancer formation. These putative stem cells maintain protumorigenic characteristics including high proliferative capacity, multipotent differentiation, drug resistance and long lifespan relative to other cells. Stem cell signaling and differentiation p...

    Full Text Available Lung cancer is the most common cause of cancer related death in men and women. It is frequently seen among men than in women and male-female ratio is 1.5:1. Common epidemiological factors that increase risk of lung cancer is smoking. Early age to start smoking, high number of smoking cigarettes per a day and depth of inhalation increase risk of lung cancer. 25% of patients with lung cancer are nonsmokers that passively exposed to cigarette smoke. Occupational exposure to substances such as asbestos, arsenic, nickel, beryllium, mustard gas increases the risk of lung cancer. The well defined risk factor is exposure to asbestos. In addition advanced age, diffuse pulmonary fibrosis, chronic obstructive pulmonary disease (COPD and genetic predisposition are the risk factors that increases lung cancer.

    Combination chemotherapy has been shown to improve overall survival compared with best supportive care in patients with advanced non-small cell lung cancer (NSCLC). The survival advantage is modest and was initially demonstrated with cisplatin-containing regimens in a large meta-analysis of randomized trials reported in 1995. Newer chemotherapy combinations have been shown to be better tolerated than older cisplatin-based combinations, and some trials have also shown greater efficacy and survival benefits with these newer combinations. Combination chemotherapy is, therefore, the currently accepted standard of care for patients with good performance statuses aged less than 70 years with advanced NSCLC. However, there are limited data from clinical trials to support the use of combination chemotherapy in elderly patients over 70 years of age with advanced NSCLC. Subgroup analyses of large randomized phase III trials suggest that elderly patients with good performance statuses do as well as younger patients treated with combination chemotherapy. There are few randomized trials reported that evaluate chemotherapy in patients aged greater than 70 years only. Based on data from trials performed by an Italian group, single-agent vinorelbine has been shown to have significant activity in elderly patients with advanced NSCLC and to be well tolerated by those patients with Eastern Cooperative Oncology Group performance statuses of two or less, with associated improvements in measures of global health.

    Aspergillus spp. is a pathogenic fungus in patients with malignancy, immunosuppression or respiratory diseases, and invasive pulmonary aspergillosis (IPA) caused by its infection is an aggressive and often lethal disorder. We report a case of non-small-cell lung cancer (NSCLC) where pneumonectomy concomitantly enabled radical cure of the underlying disease and IPA against which different antifungal drugs had been ineffective. In a patient with locally advanced NSCLC that progressed despite chemoradiation, radiation pneumonitis and subsequently cavitary disease developed following the administration of corticosteroids. Based upon the isolation of Aspergillus spp. from sputum, a diagnosis of IPA was made and since the latter was refractory to multiple antifungal drugs, pneumonectomy was undertaken which resulted in successful treatment of both NSCLC and IPA. Surgical intervention should be considered as a therapeutic option for IPA complicating NSCLC that is refractory to medical management. PMID:23505081

    Objective: To observe the efficacy and safety of cetuximab combined with chemotherapy in advanced non-small-cell lung cancer (NSCLC), and to investigate the association of status of K-RAS gene mutation and epidermal growth factor receptor (EGFR) genotype with clinical outcome.Methods: Between Jan. 2006 and Sep. 2009, nineteen patients with advanced NSCLC received cetuximab (≥4 weeks) combined with chemotherapy in Department of Thoracic Oncology at Beijing Cancer Hospital. Response, survival and toxicity were retrospectively assessed, epidermal growth factor receptor (EGFR) protein expression was evaluated by ELISA Kit. The status of K-RAS gene mutation was tested by PCR-RFLP and EGFR gene amplification was measured by EGFR fluorescence in situ hybridization (FISH).Results: Partial response(PR) was observed in 26.3%(5/19) of the patients and stable disease(SD) in 52.6%(10/19). Median progression free survival(PFS) was 6 months (95% CI: 3.6-8.4). Median overall survival (MST) and 1-year survival rate(SR) were 10.6 months (95% CI: 6.6-14.6) and 47.6%, respectively. Mild or moderate skin rash was the most common toxicity related with cetuximab. K-RAS gene mutation, EGFR protein level and amplification have little correlation with prognosis.Conclusion: Cetuximab combined with chemotherapy was tolerable and the skin rash related with cetuximab was mild to moderate. Cetuximab may prolong survival of the patients who failed to previous chemotherapy.

    The emergence of immune checkpoint inhibitors marked an important advancement in the development of cancer therapeutics. Pembrolizumab is a selective humanized IgG4 kappa monoclonal antibody that inhibits the programmed death-1 (PD-1) receptor, an integral component of immune checkpoint regulation in the tumor microenvironment. The drug is currently approved by the Food and Drug Administration for the treatment of advanced melanoma and metastatic squamous and nonsquamous non-small cell lung cancer (NSCLC). Several published studies demonstrate that single-agent pembrolizumab is safe and has efficacy in patients with NSCLC. Many ongoing protocols are investigating the role of pembrolizumab in combination with other agents in lung cancer and various other cancer types. We review the available data on pembrolizumab in NSCLC and examine the role of potential predictive biomarkers of response to therapy.

    Increases in both life expectancy and cancer incidence with age result in a significant rise in lung cancer rates among elderly patients, with a median age at diagnosis of between 63 and 70 years. However, elderly patients are under-represented in clinical trials and generally receive suboptimal treatment, mainly because of fears about increased toxicity of chemotherapy. Indeed, physiological modification of renal and haematopoietic functions with age together with co-morbidity and associated polypharmacy may alter the metabolism of chemotherapy drugs, resulting in greater toxicity. Moreover, performance status (PS), the main prognostic factor in younger patients, does not correlate well with geriatric indexes such as activities of daily living, cognition and physical performance, and comprehensive geriatric assessment is important in elderly patients. Until 2010, based on the small number of clinical trials designed for elderly patients, monotherapy was the recommended treatment for those with advanced non-small cell lung cancer (NSCLC), whereas for fit younger patients, a platinum-based doublet was and continues to be the recommended first-line therapy. However, at the plenary session of the 2010 Annual Meeting of the American Society of Clinical Oncology, results were presented from a randomized controlled trial conducted by the French Intergroup of Thoracic Oncology that demonstrated that in PS 0-2 patients aged≥70 years with advanced NSCLC, monthly carboplatin with weekly paclitaxel resulted in significantly longer survival than single-agent therapy (vinorelbine or gemcitabine). It should be noted that even in a priori unfavourable prognostic subgroups (patients with a PS score of 2, those aged>80 years or those with an activities of daily living scale score of nihilism in the treatment of elderly patients with advanced NSCLC. Such patients should be evaluated carefully by geriatric indexes and, if they have a PS score of 0-2, may be treated with platinum

    Full Text Available Recently, researchers have been increasingly finding coagulation disorders are commonly the first sign of malignancy. It has now been established that cancer development leads to an increased risk of thrombosis, and conversely, excessive activation of blood coagulation profoundly influences cancer progression. In patients with lung cancer, a sustained stimulation of blood coagulation takes place. Cancer cells trigger coagulation through expression of tissue factor, and affect coagulation through expression of thrombin, release of microparticles that augment coagulation and so on. Coagulation also facilitates tumour progression through release of platelet granule contents, inhibition of natural killer cells and recruitment of macrophages. Non-small cell lung cancer (NSCLC accounts for about 80%-85% of all lung malignancies. In the present review, we summarized the newly updated data about the physiopathological mechanisms of various components of the clotting system in different stages of carcinogenesis in NSCLC.

    Lung cancer remains a major cause of cancer-related deaths worldwide with unfavourable prognosis mainly due to the late stage of disease at presentation. High incidence and disease recurrence rates are a fact despite advances in treatment. Ongoing experimental and clinical observations suggest that the malignant phenotype in lung cancer is sustained by lung cancer stem cells (CSCs) which are putative stem cells situated throughout the airways that have the potential of initiating lung cancer ...

    Full Text Available Lung cancer is severely threatening human health. In recent years, the treatment for lung adenocarcinoma has made a great progress, targeted therapy has been widely applied in clinic, and benefits amount of patients. However, in squamous cell lung cancer, the incidence of epidermal growth factor receptor (EGFR gene mutant and ALK fusion gene are low,and targeted therapy like Tarceva and crizotinib, can hardly work. Since the fibroblast growth factors (fibroblast growth factor, FGF pathway is considered to be related to tumor cell proliferation, metastasis and angiogenesis, more and more researches proved the amplification of fibroblast growth factor receptor (FGFR in squamous cell lung cancer. Experiments in vivo and in vitro found that blocking FGF pathway could reduce the proliferation of tumor cells and inhibit metastasis. The FGF pathway might be a new target for treatment of squamous cell lung cancer. This article reviews the effect of FGFR in tumorigenesis,as well as the prospect as a therapeutic target in non-small cell lung cancer.

    Full Text Available Increasing evidence indicates that estrogen promotes tumor growth in both estrogen target organs and non-target organs. Estrogen regulates cell proliferation and differentiation via two different receptors, estrogen receptors α and β (ERα and ERβ. In recent decades, with the clarification of the ERα-mediated signaling pathways in breast cancer, targeted therapy through these pathways have successfully been used in clinical application. Tamoxifen, the classic representative, is a selective estrogen receptor modulator (SERM. Along with the elucidation of the role of estrogen in the pathophysiology of lung cancer, targeted lung cancer treatment based on the ER signaling pathways is also gradually being applied and it could become an important part of the comprehensive treatment for lung cancer.

    This study was to evaluate effect of 125I brachytherapy combined with chemotherapy on advanced non-small cell lung cancer (NSCLC). Patients with NSCLC in stages III to IV were divided into two groups: Group A (n = 27) received 125I brachytherapy combined with gemcitabine and cisplatin (GP) chemotherapy, and Group B (n = 27) received GP chemotherapy only. The results showed that the overall response rate and median progression-free survival time were 78%and 11.5 months in Group A, 41%and 8 months in Group B, respectively (P 0.05). The interventional complications in Group A included 5 patients with postoperative pneumothorax and 4 patients with hemoptysis. No patients had radiation pneumonia, radiation esophagitis or esophagotracheal fistula. Chemotherapy treatment-related toxicities were not significantly different between the two groups. The relief of tumor-associated symptoms including cough, hemoptysis, chest pain, and short breath was found in both groups, without statistical difference in remission rates between Groups A and B (P >0.05). In conclusion, 125I brachytherapy combined with chemotherapy proved to be safe and effective for treating advanced NSCLC with few complications. It improves local control rate and prolongs the progression-free survival time.

    Lung cancer is one of the most common cancers and ranks the ifrst in the mortality worldwide. The core of immunotherapy, especially cellular immunotherapy, is to activate the T cell-mediated tumor-killing effect in patients with tumors, so as to increase their anti-tumor effect. Surgery and radio- and chemotherapy cannot radically eliminate cancerous cells, but immunotherapy is an important supplementary method in killing tumor stem cells and non-proliferating cells. Cellular immunotherapy contains dendritic cells (DC), cytokine-induced killer (CIK), DC-CIK, natural killer T cells (NKT) and γδ T cells, which provides new techniques for the comprehensive treatment of lung cancer. Using CIK combined with DC, radiochemotherapy, radiofrequency ablation and monomers of Chinese medicine to induce CIK cells that directionally migrate to cancerous nest can increase tumor-killing ability and immunoregulatory ability of CIK cells, reduce adverse and toxic reactions and increase patients’ quality of life, and NKT cell and γδ T cell therapies have also been gradually perfected and promoted in clinical translation. This study mainly introduced the clinical translation of DC vaccines, CIK cells and DC-CIK treatment for lung cancer, hoping to provide new pathways and reference for the clinical treatment of lung cancer.

    Although lung cancer is the leading cause of cancer death in the USA, there have been few studies on patient-centered advanced lung cancer treatment practices. As part of a larger research study on how to use a patient-inclusive approach in late-stage lung cancer treatment, this present study describes patient, caregiver, and provider perspectives on the role of the health care system in helping patients cope with an advanced stage lung cancer diagnosis. Four focus group sessions were conducted with six to eleven participants per group for a total of 36 participants. Two focus groups were held with patients and family members/caregivers and two with physicians and nurses. A major theme that emerged concerned coping with an advanced lung cancer diagnosis, which is the subject of this paper. The patients, caregivers, and providers spoke passionately about interactions with the health care system and volunteered examples of supportive and non-supportive relationships between patients and clinicians. They advocated for better patient-provider communication practices as well as the expanded use of patient navigation and new patient orientation programs. This study contributes additional knowledge by including the perspectives of caregivers and providers who live and work closely with patients with advanced lung cancer. The findings can inform the development of comprehensive patient-centered care plans for patients living with an advanced lung cancer diagnosis. PMID:25900672

    Full Text Available We aimed to establish a laboratory prognostic index (LPI in advanced non-small cell lung cancer (NSCLC patients based on hematologic and biochemical parameters and to analyze the predictive value of LPI on NSCLC survival.The study retrospectively reviewed 462 patients with advanced NSCLC diagnosed between 2000 and 2010 in a single institution. We developed an LPI that included serum levels of white blood cells (WBC, lactate dehydrogenase (LDH, albumin, calcium, and alkaline phosphatase (ALP, based on the results of a Cox regression analysis. The patients were classified into 3 LPI groups as follows: LPI 0: normal; LPI 1: one abnormal laboratory finding; and LPI 2: at least 2 abnormal laboratory findings.The median follow up period was 44 months; the median overall survival (OS and median progression-free survival (PFS were 11 and 6 months, respectively. A multivariate analysis revealed that the following could be used as independent prognostic factors: an Eastern Cooperative Oncology Group performance status score (ECOG PS ≥2, a high LDH level, serum albumin 10.5 g/dL, number of metastases>2, presence of liver metastases, malignant pleural effusion, or receiving chemotherapy ≥4 cycles. The 1-year OS rates according to LPI 0, LPI 1, and LPI 2 were 54%, 34%, and 17% (p<0.001, respectively and 6-month PFS rates were 44%, 27%, and 15% (p<0.001, respectively. The LPI was a significant predictor for OS (Hazard Ratio (HR: 1.41; 1.05-1.88, p<0.001 and PFS (HR: 1.48; 1.14-1.93, p<0.001.An LPI is an inexpensive, easily accessible and independent prognostic index for advanced NSCLC and may be helpful in making individualized treatment plans and predicting survival rates when combined with clinical parameters.

    Lung cancer is one of malignant tumors harming human health. Over the past five decades, there is increasing morbidity and mortality of lung cancer which is the leading cause of cancer morbidity and mortality worldwide. Risk factors of lung cancer are versatile and smoking is among the important ones, but there are some non-smoking men, especially for women, some of whom developed lung cancer. Many studies showed that human papillomavirus (HPV) was the risk factor of lung cancer, however, which was less comprehensive or seriously estimated. The results of research on relationship between HPV infection and lung cancer are different because of the difference of detection methods, geographical distribution and sample size. Recently, the relationship of HPV and lung cancer is increasingly thought highly with deep study. Study advance of relationship between HPV and lung cancer in the recent years is briefly reviewed.%肺癌是严重危害人类健康的恶性肿瘤之一,近50年来其发病率和死亡率呈现不断上升趋势,肺癌的发病率和死亡率在世界范围内均居各种癌症首位.肺癌的危险因素是多方面的.吸烟是其中一个重要风险因素,但不吸烟者(特别是女性)仍有一部分会患肺癌.许多研究认为人类乳头瘤病毒(human papillomavirus,HPV)是肺癌的危险因素.然而,HPV作为肺癌的风险因素,对其进行的全面认真的评估较少.由于检测方法、地区分布、样本量等存在差异造成HPV感染和肺癌的相关性研究结果也不尽相同.近年来,随着研究的不断深入,HPV与肺癌的关系日益受到重视.现将近年关于HPV和肺癌关系的研究进展作一简要综述.

    Full Text Available Background: The optimal technique for performing lung IMRT remains poorly defined. We hypothesize that improved dose distributions associated with normal tissue sparing IMRT can allow for safe dose escalation resulting in decreased acute and late toxicity. Methods: We performed a retrospective analysis of 82 consecutive lung cancer patients treated with curative intent from 1/10 to 9/14. From 1/10 to 4/12, 44 patients were treated with the community standard of 3-dimensional conformal radiotherapy or IMRT without specific esophagus or contralateral lung constraints (standard RT. From 5/12 to 9/14, 38 patients were treated with normal tissue-sparing IMRT with selective sparing of contralateral lung and esophagus. The study endpoints were dosimetry, toxicity and overall survival.Results: Despite higher mean prescribed radiation doses in the normal tissue-sparing IMRT cohort (64.5 Gy vs. 60.8 Gy, p=0.04, patients treated with normal tissue-sparing IMRT had significantly lower lung V20, V10, V5, mean lung, maximum esophagus and mean esophagus doses compared to patients treated with standard RT (p≤0.001. Patients in the normal tissue-sparing IMRT group had reduced acute grade ≥3 esophagitis (0% vs. 11%, p<0.001, acute grade ≥2 weight loss (2% vs. 16%, p=0.04, late grade ≥2 pneumonitis (7% vs. 21%, p=0.02. The 2-year overall survival was 52% with normal tissue-sparing IMRT arm compared to 28% for standard RT (p=0.015.Conclusion: These data provide proof of principle that suboptimal radiation dose distributions are associated with significant acute and late lung and esophageal toxicity that may result in hospitalization or even premature mortality. Strict attention to contralateral lung and esophageal dose volume constraints are feasible in the community hospital setting without sacrificing disease control.

    Effects of carboxymethyllysine (CML) and pentosidine, two advanced glycation end-products (AGEs), upon invasion and migration in A549 and Calu-6 cells, two non-small cell lung cancer (NSCLC) cell lines were examined. CML or pentosidine at 1, 2, 4, 8 or 16 μmol/L were added into cells. Proliferation, invasion and migration were measured. CML or pentosidine at 4–16 μmol/L promoted invasion and migration in both cell lines, and increased the production of reactive oxygen species, tumor necrosis factor-α, interleukin-6 and transforming growth factor-β1. CML or pentosidine at 2–16 μmol/L up-regulated the protein expression of AGE receptor, p47phox, intercellular adhesion molecule-1 and fibronectin in test NSCLC cells. Matrix metalloproteinase-2 protein expression in A549 and Calu-6 cells was increased by CML or pentosidine at 4–16 μmol/L. These two AGEs at 2–16 μmol/L enhanced nuclear factor κ-B (NF-κ B) p65 protein expression and p38 phosphorylation in A549 cells. However, CML or pentosidine at 4–16 μmol/L up-regulated NF-κB p65 and p-p38 protein expression in Calu-6 cells. These findings suggest that CML and pentosidine, by promoting the invasion, migration and production of associated factors, benefit NSCLC metastasis. PMID:27517907

  1. A retrospective quality of life analysis using the lung cancer symptom scale in patients treated with palliative radiotherapy for advanced nonsmall cell lung cancer

    International Nuclear Information System (INIS)

    Purpose: To measure symptom palliation in patients treated with radiation therapy for advanced nonsmall cell lung cancer (NSCLC). Methods and Materials: Five hundred thirty patients with NSCLC were treated at the Medical College of Virginia between 1988 and 1993. Sixty-three patients with the least favorable prognostic features received palliative radiation to 30 Gy in 10 or 12 fractions for symptoms related to the presence of intrathoracic tumor. The observer portion of the Lung Cancer Symptom Scale (LCSS) was employed in a retrospective chart review, scoring measures of appetite, fatigue, cough, dyspnea, hemoptysis, and pain. Results: In 54 evaluable patients, median survival was 4 months and was independent of age, stage, performance status, or histology. Ninety-six percent of the patients had at least one LCSS symptom at presentation. Fatigue was unaffected by therapy. Improvements in appetite (p = 0.68) and pain (p = 0.61) were not statistically significant. There was, however, a statistically significant reduction in cough (p = 0.01), hemoptysis (p = 0.001), and dyspnea (p 0.0003). Self-limiting acute side effects included transient esophagitis in 37% of patients, though no severe toxicities were noted. Conclusions: These results suggest symptomatic benefit from radiotherapy even in those NSCLC patients with advanced disease and a limited life expectancy. Treatment should be given to patients whose symptoms are most amenable to palliation. A site-specific quality of life instrument such as the LCSS should be included within any future clinical trial of NSCLC management so that symptom control may be scored as a treatment outcome in addition to disease-free survival

  2. Dose escalation for unresectable locally advanced non-small cell lung cancer: end of the line?

    Radiation Therapy Oncology Group (RTOG) 0617 was a randomized trial that investigated both the impact of radiation dose-escalation and the addition of cetuximab on the treatment of non-small cell lung cancer (NSCLC). The results of RTOG 0617 were surprising, with the dose escalation randomization being closed prematurely due to futility stopping rules, and cetuximab ultimately showing no overall survival benefit. Locally advanced unresectable NSCLC has conventionally been treated with concurrent chemoradiation. Though advances in treatment technology have improved the ability to deliver adequate treatment dose, the foundation for radiotherapy (RT) has remained the same since the 1980s. Since then, progressive studies have sought to establish the safety and efficacy of escalating radiation dose to loco-regional disease. Though RTOG 0617 did not produce the anticipated result, much interest remains in dose escalation and establishing an explanation for the findings of this study. Cetuximab was also not found to provide a survival benefit when applied to an unselected population. However, planned retrospective analysis suggests that those patients with high epidermal growth factor receptor (EGFR) expression may benefit, suggesting that cetuximab should be applied in a targeted fashion. We discuss the results of RTOG 0617 and additional findings from post-hoc analysis that suggest that dose escalation may be limited by normal tissue toxicity. We also present ongoing studies that aim to address potential causes for mortality in the dose escalation arm through adaptive or proton therapy, and are also leveraging additional concurrent systemic agents such as tyrosine kinase inhibitors (TKIs) for EGFR-activating mutations or EML4-ALK rearrangements, and poly (ADP-ribose) polymerase (PARP) inhibitors.

  3. PHASE II STUDY OF GEMCITABINE AND CISPLATIN IN ADVANCED NON-SMALL CELL LUNG CANCER

    Directory of Open Access Journals (Sweden)

    M. Hoseinzadeh Mollayosefy

    2006-06-01

    Full Text Available Cisplatin-based chemotherapy is the standard treatment for advanced non-small cell lung cancer (NSCLC. Many novel drugs have been used in combination with cisplatin in this setting. Of these drugs, gemcitabine is reported to have a high response rate and acceptable toxicity. The aim of this study was to evaluate the efficacy and safety of gemcitabine and cisplatin combination. Twentythree patients with NSCLC were enrolled from January 2001 till September 2003. All of them were confirmed by histology and were in advanced stage, i.e. stage IIIB or stage IV. Cisplatin with the dose of 70 mg/m2 was given every 21 days, in combination with gemcitabine at a dose of 1250 mg/m2 administered on days 1, 8 of a 21-day cycle. Of the 23 patients, 1 showed complete remission, 5 achieved partial remission and 7 had stable disease and 2 patients showed progressive disease, 8 patients were not evaluable for response. The overall response in 15 evaluable patients was 40% (95% CI., median survival was 13.5 months (95% CI, 3.5-27.4 months, and median progression free survival was 11 months (95% CI, 1.04-20.9 months. Hematological toxicity’s included anemia, neutropenia and thrombocytopenia. Non-hematological toxicities included nausea/vomiting, peripheral neuropathy, skin rashes, mild renal impairment and one case of acute respiratory distress syndrome;another case developed transient acute psychosis. The regimen of combined gemcitabine with cisplatin is safe and effective and well tolerated in patients. In this combination, a lower dose of cisplatin seems to have an efficacy similar to that seen in previous reports.

  4. Molecular Therapeutic Advances in Personalized Therapy of Melanoma and Non-Small Cell Lung Cancer

    Directory of Open Access Journals (Sweden)

    Fergal C. Kelleher

    2012-04-01

    Full Text Available The incorporation of individualized molecular therapeutics into routine clinical practice for both non-small cell lung cancer (NSCLC and melanoma are amongst the most significant advances of the last decades in medical oncology. In NSCLC activating somatic mutations in exons encoding the tyrosine kinase domain of the Epidermal Growth Factor Receptor (EGFR gene have been found to be predictive of a response to treatment with tyrosine kinase inhibitors (TKI, erlotinib or gefitinib. More recently the EML4-ALK fusion gene which occurs in 3–5% of NSCLC has been found to predict sensitivity to crizotinib an inhibitor of the anaplastic lymphoma kinase (ALK receptor tyrosine kinase. Similarly in melanoma, 50% of cases have BRAF mutations in exon 15 mostly V600E and these cases are sensitive to the BRAF inhibitors vemurafenib or dabrafenib. In a Phase III study of advanced melanoma cases with this mutation vemurafenib improved survival from 64% to 84% at 6 months, when compared with dacarbazine. In both NSCLC and melanoma clinical benefit is not obtained in patients without these genomic changes, and moreover in the case of vemurafenib the therapy may theoretically induce proliferation of cases of melanoma without BRAF mutations. An emerging clinical challenge is that of acquired resistance after initial responses to targeted therapeutics. Resistance to the TKI’s in NSCLC is most frequently due to acquisition of secondary mutations within the tyrosine kinase of the EGFR or alternatively activation of alternative tyrosine kinases such as C-MET. Mechanisms of drug resistance in melanoma to vemurafenib do not involve mutations in BRAF itself but are associated with a variety of molecular changes including RAF1 or COT gene over expression, activating mutations in RAS or increased activation of the receptor tyrosine kinase PDGFRβ. Importantly these data support introducing re-biopsy of tumors at progression to continue to personalize the choice of

    Lung cancer is the principal cause of cancer-related mortality in the developed world, accounting for almost one-quarter of all cancer deaths. Traditional treatment algorithms have largely relied on histologic subtype and have comprised pragmatic chemotherapy regimens with limited efficacy. However, because our understanding of the molecular basis of disease in non-small cell lung cancer (NSCLC) has improved exponentially, it has become apparent that NSCLC can be radically subdivided, or molecularly characterized, based on recurrent driver mutations occurring in specific oncogenes. We know that the presence of such mutations leads to constitutive activation of aberrant signaling proteins that initiate, progress, and sustain tumorigenesis. This persistence of the malignant phenotype is referred to as "oncogene addiction." On this basis, a paradigm shift in treatment approach has occurred. Rational, targeted therapies have been developed, the first being tyrosine kinase inhibitors (TKIs), which entered the clinical arena > 10 years ago. These were tremendously successful, significantly affecting the natural history of NSCLC and improving patient outcomes. However, the benefits of these drugs are somewhat limited by the emergence of adaptive resistance mechanisms, and efforts to tackle this phenomenon are ongoing. A better understanding of all types of oncogene-driven NSCLC and the occurrence of TKI resistance will help us to further develop second- and third-generation small molecule inhibitors and will expand our range of precision therapies for this disease.

  8. The role of prophylactic cranial irradiation in regionally advanced non-small cell lung cancer. A Southwest Oncology Group Study

    International Nuclear Information System (INIS)

    Lung cancer is the most common malignant disease in the United States. Only the few tumors detected very early are curable, but there has been some progress in the management of more advanced non-small cell lung cancer, particularly in regionally inoperable disease. Prevention of central nervous system relapse is an important issue in this group of patients because brain metastases ultimately develop in 20% to 25% of them. Seventy-three patients with regionally advanced non-small cell lung cancer were entered into a Phase II trial of neutron chest radiotherapy sandwiched between four cycles of chemotherapy including cisplatin, vinblastine, and mitomycin C. Prophylactic cranial irradiation was administered concurrently with chest radiotherapy (3000 cGy in 10 fractions in 15 patients; 3600 cGy in 18 fractions in the remaining 50 patients). Patients underwent computed tomographic scan of the brain before treatment and every 3 months after treatment. The initial overall response rate was 79%, but 65 of the 73 patients have subsequently died of recurrent disease. Median follow-up is 9 months for all 73 patients and 26 months for eight long-term survivors. No patient who completed the prophylactic cranial irradiation program had clinical or radiologic brain metastases. Toxic reactions to prophylactic cranial irradiation included reversible alopecia in all patients, progressive dementia in one patient, and possible optic neuritis in one patient. Both of these patients received 300 cGy per fraction of irradiation. The use of prophylactic cranial irradiation has been controversial, but its safety and efficacy in this trial supports its application in a group of patients at high risk for central nervous system relapse. Further evaluation of prophylactic cranial irradiation in clinical trials for regionally advanced non-small cell lung cancer is warranted

Prophylactic cranial irradiation was administered concurrently with chest radiotherapy (3000 cGy in 10 fractions in 15 patients; 3600 cGy in 18 fractions in the remaining 50 patients). Patients underwent computed tomographic scan of the brain before treatment and every 3 months after treatment. The initial overall response rate was 79%, but 65 of the 73 patients have subsequently died of recurrent disease. Median follow-up is 9 months for all 73 patients and 26 months for eight long-term survivors. No patient who completed the prophylactic cranial irradiation program had clinical or radiologic brain metastases. Toxic reactions to prophylactic cranial irradiation included reversible alopecia in all patients, progressive dementia in one patient, and possible optic neuritis in one patient. Both of these patients received 300 cGy per fraction of irradiation. The use of prophylactic cranial irradiation has been controversial, but its safety and efficacy in this trial supports its application in a group of patients at high risk for central nervous system relapse. Further evaluation of prophylactic cranial irradiation in clinical trials for regionally advanced non-small cell lung cancer is warranted.

  10. Influence of interventional chemotherapy combined with traditional Chinese medicine on the immune function of elderly patients with advanced lung cancer

    International Nuclear Information System (INIS)

    Objective: To investigate the influence of interventional chemotherapy combined with traditional Chinese medicine on the immune function in elderly patients with advanced lung cancer and to establish a comprehensive therapeutic pattern which is effective and economical with lower side-effects. Methods: A total of 60 aged patients with lung cancer were randomly and equally divided into two groups with 30 patients in each group. Patients in group A were purely treated with traditional Chinese medicine and patients in group B were treated with a combination of interventional chemotherapy and traditional Chinese medicine. And two therapeutic courses (6-8 weeks) were conducted in both groups. The serum T-lymphocyte subsets levels of CD3, CD4, CD8, CD4/CD8, NK cells and CD4+CD25+ Treg cell levels were estimated with flow cytometry. The results were statistically analyzed. Results: No significant difference in serum levels of T cell subsets and CD4+CD25+ Treg cell levels existed between the two groups, both before and after the treatment (P > 0.05). However, after the treatment the CD4+CD25+ Treg cell level in group B was significantly lower than that in group A (P < 0.05). The short-term effective rate and the total clinical benefit rate in group B were 40% and 73.3% respectively, which were much better than those in group A (20% and 63.3% respectively). Conclusion: Interventional chemotherapy combined with traditional Chinese medicine will not damage the immune function of elderly patients with advanced lung cancer, on the contrary, the combination therapy, through effectively reducing the suppressor T cell level,shows excellent short-term effect. It indicates that interventional chemotherapy combined with Chinese medicine is an effective comprehensive therapeutic mode for elderly patients with advanced lung cancer. (authors)

    Since publication of the Radiologic Diagnostic Oncology Group Report in 1991, the clinical application of pulmonary magnetic resonance (MR) imaging to patients with lung cancer has been limited. Computed tomography has been much more widely available for staging of lung cancer in clinical situations. Currently, ventilation and perfusion scintigraphy is the only modality that demonstrates pulmonary function while 2-[fluorine-18]-fluoro-2-deoxy-D-glucose positron emission tomography is the only modality that reveals biological glucose metabolism of lung cancer. However, recent advancements in MR imaging have made it possible to evaluate morphological and functional information in lung cancer patients more accurately and quantitatively. Pulmonary MR imaging may hold significant potential to substitute for nuclear medicine examinations. In this review, we describe recent advances in MR imaging of lung cancer, focusing on (1) characterization of solitary pulmonary nodules; (2) differentiation from secondary change; evaluation of (3) medastinal invasion, (4) chest wall invasion, (5) lymph node metastasis, and (6) distant metastasis; and (7) pulmonary functional imaging. We believe that further basic studies, as well as clinical applications of newer MR techniques, will play an important role in the management of patients with lung cancer.

    Lung cancer is the most common cancer worldwide and is the leading cause of cancer death for both men and women in the USA. Symptom burden in patients with advanced lung cancer is very high and has a negative impact on their quality of life (QOL). Palliative care with its focus on the management of symptoms and addressing physical, psychosocial, spiritual, and existential suffering, as well as medically appropriate goal setting and open communication with patients and families, significantly adds to the quality of care received by advanced lung cancer patients. The Provisional Clinical Opinion (PCO) of American Society of Clinical Oncology (ASCO) as well as the National Cancer Care Network's (NCCN) clinical practice guidelines recommends early integration of palliative care into routine cancer care. In this chapter, we will provide an overview of palliative care in lung cancer and will examine the evidence and recommendations with regard to a comprehensive and interdisciplinary approach to symptom management, as well as discussions of goals of care, advance care planning, and care preferences.

    Lung cancer continues to be one of the most common causes of cancer death despite understanding the major cause of the disease: cigarette smoking. Smoking increases lung cancer risk 5- to 10-fold with a clear dose-response relationship. Exposure to environmental tobacco smoke among nonsmokers increases lung cancer risk about 20%. Risks for marijuana and hookah use, and the new e-cigarettes, are yet to be consistently defined and will be important areas for continued research as use of these products increases. Other known environmental risk factors include exposures to radon, asbestos, diesel, and ionizing radiation. Host factors have also been associated with lung cancer risk, including family history of lung cancer, history of chronic obstructive pulmonary disease and infections. Studies to identify genes associated with lung cancer susceptibility have consistently identified chromosomal regions on 15q25, 6p21 and 5p15 associated with lung cancer risk. Risk prediction models for lung cancer typically include age, sex, cigarette smoking intensity and/or duration, medical history, and occupational exposures, however there is not yet a risk prediction model currently recommended for general use. As lung cancer screening becomes more widespread, a validated model will be needed to better define risk groups to inform screening guidelines. PMID:26667337

    2016-01-01

    Lung cancer is the leading cause of cancer mortality in the United States and worldwide. Since lung cancer outcomes are dependent on stage at diagnosis with early disease resulting in longer survival, the goal of screening is to capture lung cancer in its early stages when it can be treated and cured. Multiple studies have evaluated the use of chest X-ray (CXR) with or without sputum cytologic examination for lung cancer screening, but none has demonstrated a mortality benefit. In contrast, the multicenter National Lung Screening Trial (NLST) from the United States found a 20 % reduction in lung cancer mortality following three consecutive screenings with low-dose computed tomography (LDCT) in high-risk current and former smokers. Data from European trials are not yet available. In addition to a mortality benefit, lung cancer screening with LDCT also offers a unique opportunity to promote smoking cessation and abstinence and may lead to the diagnoses of treatable chronic diseases, thus decreasing the overall disease burden. The risks of lung cancer screening include overdiagnosis, radiation exposure, and false-positive results leading to unnecessary testing and possible patient anxiety and distress. However, the reduction in lung cancer mortality is a benefit that outweighs the risks and major health organizations currently recommend lung cancer screening using age, smoking history, and quit time criteria derived from the NLST. Although more research is needed to clearly define and understand the application and utility of lung cancer screening in the general population, current data support that lung cancer screening is effective and should be offered to eligible beneficiaries.

    Lung cancer is an extremely heterogeneous disease, with well over 50 different histological variants recognized under the fourth revision of the World Health Organization (WHO) typing system. Because these variants have differing genetic and biological properties correct classification of lung cancer is necessary to assure that lung cancer patients receive optimum management. Due to the recent understanding that histologic typing and EGFR mutation status are important for target the therapy in lung adenocarcinoma patients there was a great need for a new classification that addresses diagnostic issues and strategic management to allow for molecular testing in small biopsy and cytology specimens. For this reason and in order to address advances in lung cancer treatment an international multidisciplinary classification was proposed by the International Association for the Study of Lung Cancer (IASLC), American Thoracic Society (ATS), and European Respiratory Society (ERS), further increasing the histological heterogeneity and improving the existing WHO-classification. Is now the beginning of personalized therapy era that is ideally finalized to treat each individual case of lung cancer in different way. PMID:26667341

    Full Text Available Background and objective Icotinib hydrochloride is the third single target EGFR-TKI used in clinical treatment of advanced non-small cell lung cancer (NSCLC. Clinical research reports on its efficacy and survival in patients with Recurrent Advanced NSCLC are still little.The aim of this study is to evaluate the efficacy and survival of Icotinib hydrochloride for patients with advanced non-small cell lung cancer who failed to previous chemotherapy and explore the association of clinical features with the efficacy and survival. Methods The clinical data of 60 NSCLC patients referred to the Beijing Chest Hospital, Capital Medical University from March 2009 to July 2012 were retrospectively analyzed. Results The overall response rate (ORR was 45.0% and the disease control rate (DCR was 80.0%. The median progression-free survival (PFS time was 6.7 months. RR and PFS in female were superior to male (P=0.014, 0.013, respectively. RR, DCR in 2nd-line subgroup were superior to ≥3rd-line subgroup (P=0.020, 0.024, respectively. RR, DCR and PFS in EGFR mutation carriers were significantly superior to wild-type patients (P=0.006, <0.001, 0.002, respectively . There was no statistical difference in RR and PFS between those age <65 and ≥65 or PS<2 and PS≥2. There was no statistical difference in RR and DCR between exon 19 deletion and exon 21 mutations, while the former had much longer PFS (P=0.020. EGFR mutation and exon 19 deletion are the independent prognostic factors to significantly improve the PFS (P=0.009, 0.012, respectively. The side effects were generally mild and consisted of rash and diarrhea. Conclusion Icotinib hydrochloride is effective especially in EGFR mutation carriers and well tolerated in patients with recurrent advanced non-small-cell lung cancer.

    Full Text Available Background and objective Icotinib is the first self-developed small molecular drug in China for targeted therapy of lung cancer. Compared to the other two commercially available epidermal growth factor receptor (EGFR tyrosine kinase inhibitors, gefitinib and erlotinib, icotinib is similar to them in chemical structure, mechanism of activity and therapeutic effects. To explore the efficacy and side effects of icotinib hydrochloride in the treatment of the advanced non-small cell lung cancer (NSCLC patients with EGFR mutation and wild-type. Methods Patients with advanced NSCLC who were treated with icotinib hydrochloride in Beijing Chest Hospital were retrospective analyzed from March 2009 to December 2014. Results The clinical data of 124 patients (99 with EGFR mutation and 25 with wild type with advanced NSCLC were enrolled in this study. The patients’ overall objective response rate (ORR was 51.6 % and the disease control rate (DCR was 79.8%; The patients with EGFR mutation, ORR was 63.6%, DCR was 93.9%. The ORR was 4.0% and the DCR was 24.0% in the wild-type patients. Median progression-free survival (PFS with icotinib treatment in EGFR mutation patients was 10.5 months and 1.0 month in wild-type patients. The major adverse events were mild skin rash (30.6% and diarrhea (16.1%. Conclusion Monotherapy with icotinib hydrochloride is effective and tolerable for the advanced NSCLC EGFR mutation patients.

  6. Risk factors for radiation induced lung toxicity in locally advanced non-small cell lung cancer treated with three-dimensional radiotherapy

    International Nuclear Information System (INIS)

    Objective: To investigate the patient and treatment related predictors for the development of radiation induced lung toxicity (RILT) in patients with locally advanced non-small cell lung cancer (NSCLC) receiving definitive three-dimensional radiotherapy. Methods: Data were retrospectively collected from inoperable or unresectable 253 patients with stage III NSCLC treated with definitive three-dimensional radiotherapy between January 2001 and April 2007. National cancer institute common toxicity criteria version 3.0 was employed to evaluate the classification of RILT and grade ≥2 toxicity served as the endpoint. The correlation between RILT and aforementioned factors was analyzed. Results: The grade ≥ 2 RILT was 26.5%. Univariate analysis showed age, FEV1%, DLCO%, contralateral lung (CL) V5 -V15, ipsilateral lung (IL) V5 -V40, total lung (TL) V5 -V50, IL and TL mean lung dose (MLD) were significantly correlated with the development of RILT (χ2 =4.46 - 23.99, P = 0.000 - 0.035). Multivariate analysis showed TL MLD >17.5 Gy and FEV1% ≥72% were significantly correlated with the development of RILT (χ2 = 17.49, 9.30, P = 0.000, 0.002). Patients were stratified into four groups according to MLD and FEV1%, corresponding to the RILT incidence of 9.3%, 24.7%, 38.5% and 63.6%, respectively (χ2 =25.27, P = 0.000). Conclusions: TL MLD and baseline FEV1% are significant factors correlated with the development of RILT in NSCLC patients treated with three-dimensional radiation therapy. The combination of TL MLD and FEV1% may help classify NSCLC patients per risk of RILT and subsequently direct risk-adaptive radiation therapy. Poor baseline pulmonary function does not increase the risk of RILT and may even be associated with lower RILT probability, which has yet to be validated in larger patient cohorts. (authors)

    The occurrence of pulmonary tuberculosis (PTB) and lung cancer as comorbidities has been extensively discussed in many studies. In the past, it was well known that lung cancer is a specific epidemiological successor of PTB and that lung cancer often develops in scars caused by PTB. In recent years, the relevance of the two diseases has drawn attention in terms of the close epidemiological connection and chronic inflammation-associated carcinogenesis. In Japanese case series studies, most lung cancer patients with tuberculous sequelae received supportive care alone in the past, but more recently, the use of aggressive lung cancer treatment is increasing. Many studies on PTB and lung cancer as comorbidities have revealed that active PTB is noted in 2-5% of lung cancer cases, whereas lung cancer is noted in 1-2% of active PTB cases. In such instances of comorbidity, many active PTB cases showed Type II (non-extensively cavitary disease) and Spread 2-3 (intermediate-extensive diseases) on chest X-rays, but standard anti-tuberculosis treatment easily eradicates negative conversion of sputum culture for M. tuberculosis; lung cancer cases were often stage III- IV and squamous cell carcinoma predominant, and the administration of aggressive treatment for lung cancer is increasing. The major clinical problems associated with PTB and lung cancer as comorbidities include delay in diagnosis (doctor's delay) and therapeutic limitations. The former involves two factors of radiographic interpretation: the principles of parsimony (Occam's razor) and visual search; the latter involves three factors of lung cancer treatment: infectivity of M.tuberculosis, anatomical limitation due to lung damage by tuberculosis, and drug-drug interactions between rifampicin and anti-cancer drugs, especially molecularly targeted drugs. The comorbidity of these two diseases is an important health-related issue in Japan. In the treatment of PTB, the possibility of concurrent lung cancer should be kept

    Full Text Available Abstract Background Lung cancer is a malignant carcinoma which has the highest morbidity and mortality in Chinese population. Gefitinib, a tyrosine kinase (TK inhibitor of epidermal growth factor receptor (EGFR, displays anti-tumor activity. The present data regarding first-line treatment with single agent gefitinib against non-small-cell lung cancer (NSCLC in Chinese population are not sufficient. Purpose To assess the efficacy and toxicity of gefitinib in Chinese patients with advanced non-small-cell lung cancer (NSCLC, a study of single agent treatment with gefitinib in Chinese patients was conducted. Methods 45 patients with advanced NSCLC were treated with gefitinib (250 mg daily until the disease progression or intolerable toxicity. Results Among the 45 patients, 15 patients achieved partial response (PR, 17 patients experienced stable disease (SD, and 13 patients developed progression disease (PD. None of the patients achieved complete response (CR. The tumor response rate and disease control rate was 33% and 71.1%, respectively. Symptom remission rate was 72.5%, and median remission time was 8 days. Median overall survival and median progression-free survival was 15.3 months and 6.0 months, respectively. The main induced toxicities by gefitinib were skin rash and diarrhea (53.3% and 33.3%, respectively. The minor induced toxicities included dehydration and pruritus of skin (26.7% and 22.2%, respectively. In addition, hepatic toxicity and oral ulceration occurred in few patients (6.7% and 4.4%2, respectively. Conclusions Single agent treatment with gefitinib is effective and well tolerated in Chinese patients with advanced NSCLC.

  11. The cost of treating advanced non-small cell lung cancer: estimates from the chinese experience.

    Directory of Open Access Journals (Sweden)

    Xiaohui Zeng

    Full Text Available BACKGROUND: Because of the potentially significant economic burden of healthcare costs associated with many diseases, it is critical that regulatory and medical insurance organisations collect and utilise data on the cost-effectiveness of care provision to make rational policy decisions. However, little is known about healthcare costs in China. METHODOLOGY/PRINCIPAL FINDINGS: Based on health expenditure data for 253 cases of advanced non-small cell lung cancer (NSCLC registered at the Second Xiangya Hospital of Central South University in China between 2006 and 2010, the cost of care provision was analysed. The monthly and aggregate annual medical costs were estimated for patients who were in either a progression-free state (PFS or a disease-progression state (DPS. Monthly healthcare costs accumulated during the terminal 3 months were collected separately. The mean cost of treatment for PFS and DPS patients over one year was approximately US$11,566 and $14,519, respectively. The monthly costs for all patients were higher initially than in the subsequent months (PFS: $2,490; DPS: $2,503. For PFS patients, healthcare expenditures stabilised after the 7th month, with a mean monthly medical expenditure of $82.49. For DPS patients, expenditures stabilised after the 9th month, and the mean expenditure during the 9th month was $307.9. Medical care costs in the three successive months prior to death were $3,754, $5,829 and $7,372, respectively. CONCLUSIONS/SIGNIFICANCE: The economic evaluation of health care technologies is becoming ever more important in China, especially in disease areas for which new and expensive therapies are being introduced on a regular basis. This is first paper to present empirically estimated China-specific costs associated with the treatment of NSCLC. The cost estimates are presented in a format that is specifically intended to inform cost-effectiveness analyses of treatments for NSCLC, and hence, contribute to the more

    Most patients with lung cancer are diagnosed when they present with symptoms, they have advanced stage disease, and curative treatment is no longer an option. An effective screening test has long been desired for early detection with the goal of reducing mortality from lung cancer. Sputum cytology, chest radiography, and computed tomography (CT) scan have been studied as potential screening tests. The National Lung Screening Trial (NLST) demonstrated a 20% reduction in mortality with low-dose CT (LDCT) screening, and guidelines now endorse annual LDCT for those at high risk. Implementation of screening is underway with the desire that the benefits be seen in clinical practice outside of a research study format. Concerns include management of false positives, cost, incidental findings, radiation exposure, and overdiagnosis. Studies continue to evaluate LDCT screening and use of biomarkers in risk assessment and diagnosis in attempt to further improve outcomes for patients with lung cancer. PMID:27158468

    Full Text Available Abstract Treatment of non-small-cell lung cancer is dependent on disease stage. For patients with metastasis or locally advanced disease, the importance of finding therapeutic schemes that may benefit this population is important. This review discusses therapeutic options for first- and second-line treatment in patients with advanced non-small-cell lung cancer. According to current data, the combination of two cytotoxic agents is the optimum first-line treatment for patients with non-small-cell lung cancer and performance status of 0–1. Addition of bevacizumab has shown to provide an even longer survival and to increase response rate. Within the first-line setting, erlotinib appears to be effective in the treatment of elderly patients who would not derive a benefit from standard chemotherapy or those refusing standard chemotherapy. The administration of erlotinib as first-line maintenance therapy is being assessed. There are currently three drugs approved for second-line treatment of patients with advanced non-small-cell lung cancer after failure of first-line chemotherapy. These drugs have proven to be effective in phase III trials. In the phase III trial BR.21 study, the response rate was 8.9% in the erlonitib group, and less than 1% in placebo; median response duration was 7.9 months and 3.7 months, respectively; and the median survival was 6.7 months and 4.7 with erlotinib and placebo, respectively. One-year survival was 31% and 21% with erlotinib and placebo, respectively. In addition, the BR.21 trial revealed that significantly greater improvements in overall quality of life and in both physical and emotional functioning were observed in the erlotinib arm as compared with the placebo arm. Erlotinib is not significantly associated with hematologic adverse effects. Erlotinib is administered orally, and does not require concomitant administration of other drugs, thus causing patients less inconvenience. Analysis of data from different

Methods: Twenty-five patients with advanced NSCLC were treated with paclitaxel and carboplatin for 2 to 4 cycles before undergoing tumor resection and then postoperative chemotherapy/radiotherapy therapy for 2 to 4 cycles. Results: Following neoadjuvant chemotherapy, the most prominent side-effect was bone marrow restraint. The overall response rate of preoperative chemotherapy was 56%. The mean survival time was 26.5 months, with 1-, 2- and 5-year survival rates of 55%, 25%, and 16%, respectively. All NSCLC patients survived the perioperative period. Conclusion: Preoperative neoadjuvant chemotherapy combining paclitaxel and carboplatin produced minimal side-effect while increasing the probability that advanced NSCLC patients would be able to undergo surgery thus improving their prognosis.

    During the past 15 years, treatment of stage IIIA (N2) non-small cell lung cancer has evolved considerably because of improvements in patients selection, staging, and combined modality therapy. Results of several clinical trials suggest that induction chemotherapy or chemoradiation and surgical resection is superior to surgery alone. However, the optimal induction regimen has not been defined. An intergroup trial is also underway to determine whether chemoradiation and surgical resection leads to better survival than chemotherapy and radiation alone. Future studies will assess ways to combine radiation and novel chemotherapeutic agents, and will identify molecular abnormalities that predict response to induction therapy.

    Lung cancer has not traditionally been viewed as an immune-responsive tumor. However, it is becoming evident that tumor-induced immune suppression is vital to malignant progression. Immunotherapies act by enhancing the patient's innate immune response and hold promise for inducing long-term responses in select patients with non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Immune checkpoint inhibitors, in particular, inhibitors to cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and programmed death 1 (PD-1) and programmed death receptor ligand 1 (PD-L1) have shown promise in early studies and are currently in clinical trials in both small cell lung cancer and non-small cell lung cancer patients. Two large randomized phase III trials recently demonstrated superior overall survival (OS) in patients treated with anti-PD-1 therapy compared to chemotherapy in the second-line setting.

    Full Text Available OBJECTIVE: To investigate the clinical significance of the expression of MHC class I chain-related gene A (MICA in patients with advanced non-small cell lung cancer and explore the relationship between MICA expression and the efficacy of cytokine-induced killer cell (CIK therapy for treating advanced non-small cell lung cancer. METHODS: We obtained data on 222 patients with advanced non-small cell lung cancer, including data on MICA expression, age, gender, ECOG score, pathological type, stage, treatment history (including 38 patients who were given autologous CIK cell infusion, and overall survival (OS. MICA expression in lung cancer tissue was evaluated by immunohistochemical staining. Analyses of MICA expression, and CIK therapy association with survival outcomes were performed using Cox proportional models, Kaplan-Meier methods, and the log-rank test. RESULT: s MICA was expressed in both membrane and cytoplasm. MICA expression correlated with the stage of lung cancer, ECOG score, gender and age. Multivariate COX regression analysis showed that the expression of MICA was an independent prognostic factor of advanced non-small cell lung cancer (p = 0.002. In subgroup analysis, we divided the 222 patients into CIK and control groups. In the CIK group, the medium OS (mOS of patients with a high expression of MICA was longer than in those with low expression of MICA (27 months vs. 13 months. In the control group, the mOS in patients with a high expression of MICA was shorter than in patients with low MICA expression (9 months vs. 18 months. COX regression analysis showed that the MICA expression affects the effect of CIK therapy (p<0.0001. CONCLUSION: 1 The high expression of MICA is one of the indicators of a poor prognosis for advanced non-small cell lung cancer patients. 2 The high expression of MICA might be one of the predictive factors for successful CIK therapy.

  2. Interstitial lung abnormalities in treatment-naïve advanced non-small-cell lung cancer patients are associated with shorter survival

    International Nuclear Information System (INIS)

    Highlights: • Interstitial lung abnormalities were present in 14% of stage IV NSCLC patients. • ILA was more common in older patients with heavier smoking history. • ILA was associated with shorter survival after adjusting for smoking and therapy. • ILA could be an additional independent marker for survival in advanced NSCLC. - Abstract: Objective: Interstitial lung diseases are associated with increased risk of lung cancer. The prevalence of ILA at diagnosis of advanced non-small-cell lung cancer (NSCLC) and its impact on overall survival (OS) remain to be investigated. Materials and method: The study included 120 treatment-naïve stage IV NSCLC patients (53 males, 67 females). ILA was scored on CT prior to any systemic therapy using a 4-point scale [0 = no evidence of ILA, 1 = equivocal for ILA, 2 = suspicious for ILA, 3 = ILA] by a sequential reading method previously reported. ILA scores of 2 or 3 indicated the presence of ILA. Results: ILA was present in 17 patients (14%) with advanced NSCLC prior to any treatment (score3: n = 2, score2: n = 15). These 17 patients were significantly older (median age: 69 vs. 63, p = 0.04) and had a heavier smoking history (median: 40 vs. 15.5 pack-year, p = 0.003) than those with ILA score 0 or 1. Higher ILA scores were associated with shorter OS (p = 0.001). Median OS of the 17 patients with ILA was 7.2 months [95%CI: 2.9–9.4] compared to 14.8 months [95%CI: 11.1–18.4] in patients with ILA score 0 or 1 (p = 0.002). In a multivariate model, the presence of ILA remained significant for increased risk for death (HR = 2.09, p = 0.028) after adjusting for first-line systemic therapy (chemotherapy, p < 0.001; TKI, p < 0.001; each compared to no therapy) and pack years of smoking (p = 0.40). Conclusion: Radiographic ILA was present in 14% of treatment-naïve advanced NSCLC patients. Higher ILA scores were associated with shorter OS, indicating that ILA could be a marker of shorter survival in advanced NSCLC

  5. Efficacy and safety of gefitinib as monotherapy for Chinese patients with advanced non-small cell lung cancer

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    @@ Platinum-based chemotherapy can improve the survival and quality of life of patients with locally advanced and metastatic lung cancer. Second-line docetaxel monotherapy can improve overall survival following the failure of first line chemotherapy. However, many limiting factors such as poor performance status, advanced age, adverse effects of chemotherapy and reluctance to receive cytotoxic chemotherapeutic agents render patients unable to accept chemotherapy. Furthermore, for patients who have failed second-line chemotherapy treatment options are often limited to best support care or palliative radiotherapy. 1 Gefitinib (Iressa) is a HER1/EGFR (epidermal growth factor receptor)- tyrosine kinase inhibitor approved in a number of countries including the US, Japan and recently China for the treatment of patients with non-small cell lung cancer (NSCLC), who have failed platinum/docetaxel-based first line and second line chemotherapy. 2,3 Current data show heterogeneity in response to gefitinib among people of different ethnic origin, but there is very little data concerning the safety and efficacy of gefitinib in Chinese patients. This paper aims to summarize the safety and efficacy data for gefitinib 250 mg treatment in Chinese NSCLC patients at Peking Union Medical College Hospital who received gefitinib as part of an Expanded Access Programme.

    Objective: To evaluate the addition of vindesine to a cyclophosphamide-epirubicin-cisplatin (CAP) regimen for treating the patients with locally advanced non-small cell lung cancer (NSCLC). Methods: From May 1994to August 1998, 59 previously untreated patients with stage Ⅲa and Ⅲb non-small cell lung cancer were enrolled into this trial. Patients characteristics were the following: the median age was 52 years; the median performance status was 1; there were 19 stage Ⅲa and 40 stage Ⅲb; there were 47 adenocarcinoma, 10squamous cell carcinoma and 2 large cell carcinoma. All patients were treated with vindesine (2 mg/m2, on day 1and day 8), cyclophosphamide (0.6/m2, on day 1),epirubicin (40 mg/m2, on day 1) and cisplatin (60 mg/m2,on day 1) every 3 or 4 weeks. Results: Four achieved a complete response (6.8%), 29 achieved a partial response (49.2%), 15 had stable disease, and 10 had progressive disease. A clinical improvement was in 45 of 59 patients (76.3%). The most frequent major toxic effects were myelosuppression, nausea and vomiting.Conclusion: The vindesine with CAP regimen was active combination chemotherapy in patients with locally advanced NSCLC accompanied by the limited side effects.

  8. SU-E-T-572: Normal Lung Tissue Sparing in Radiation Therapy for Locally Advanced Non-Small Cell Lung Cancer

    International Nuclear Information System (INIS)

    Purpose: To compare normal lung-sparing capabilities of three advanced radiation therapy techniques for locally advanced non-small cell lung cancer (LA-NSCLC). Methods: Four-dimensional computed tomography (4DCT) was performed in 10 patients with stage IIIb LA-NSCLC. The internal target volume (ITV); planning target volume (PTV); and organs at risks (OARs) such as spinal cord, total normal lung, heart, and esophagus were delineated for each CT data set. Intensity-modulated radiation therapy (IMRT), Tomohelical-IMRT (TH-IMRT), and TomoDirect-IMRT (TD-IMRT) plans were generated (total prescribed dose, 66 Gy in 33 fractions to the PTV) for each patient. To reduce the normal lung dose, complete and directional block function was applied outside the normal lung far from the target for both TH-IMRT and TD-IMRT, while pseudo- OAR was set in the same region for IMRT. Dosimetric characteristics of the three plans were compared in terms of target coverage, the sparing capability for the OAR, and the normal tissue complication probability (NTCP). Beam delivery efficiency was also compared. Results: TH-IMRT and TD-IMRT provided better target coverage than IMRT plans. Lung volume receiving ≥–30 Gy, mean dose, and NTCP were significant with TH-IMRT than with IMRT (p=0.006), and volume receiving ≥20–30 Gy was lower in TD-IMRT than in IMRT (p<0.05). Compared with IMRT, TH-IMRT had better sparing effect on the spinal cord (Dmax, NTCP) and heart (V45) (p<0.05). NTCP for the spinal cord, V45 and V60 for the heart, and Dmax for the esophagus were significantly lower in TD-IMRT than in IMRT. The monitor units per fraction were clearly smaller for IMRT than for TH-IMRT and TD-IMRT (p=0.006). Conclusion: In LA-NSCLC, TH-IMRT gave superior PTV coverage and OAR sparing compared to IMRT. TH-IMRT provided better control of the lung volume receiving ≥5–30 Gy. The delivery time and monitor units were lower in TD-IMRT than in TH-IMRT

    1989-02-20

    Lung cancer is the leading cause of death of cancer in Australian men and the third leading cause in Australian women. Efforts are being made to reduce the incidence of this disease by smoking-cessation programmes and improved industrial hygiene, and these measures need to be encouraged strongly by all sectors of the community. On a population basis, insufficient evidence is available to justify screening procedures for the early detection of lung cancer in "at-risk" groups. Cure is possible by surgical resection in early cases. Improvements in therapeutic results with traditional cancer treatments largely have reached a plateau, but a number of newer therapies, and combinations of standard therapies, currently are being evaluated. Of particular interest is concurrent radiotherapy and chemotherapy in localized non-small-cell lung cancer; laser "debulking" in conjunction with radiotherapy in non-small-cell lung cancer, and biological response-modifying agents in non-small-cell and small-cell lung cancer. It is important that data be collected adequately to define epidemiological changes and to evaluate treatment results (including repeat bronchoscopy, to assess local control of tumour), and that the quality of life is recorded and reported in the evaluation process. Finally, phase-III studies in lung-cancer treatments require adequate numbers of subjects to enable meaningful conclusions to be achieve objectives within a reasonable study period. PMID:2469943

    Abstract Background: Brain metastases (BMs) are a common and serious complication of non-small cell lung cancer (NSCLC). Whole-brain radiotherapy (WBRT), surgery, and molecular targeted therapy are usually used to treat NSCLC with BM. Chemotherapeutic options for BM are limited by tumor resistance, ineffective agents, and the blood–brain barrier. Pemetrexed/cisplatin is the preferred chemotherapy in nonsquamous NSCLC, but the efficacy of this treatment for nonsquamous NSCLC with BM is uncertain. Methods: We present a case of nonsquamous NSCLC with asymptomatic BM presenting with irritating cough and right shoulder back pain (unknown sensitizing epidermal growth factor receptor mutations or anaplastic lymphoma kinase). Results: He benefited from administration of first-line chemotherapy of pemetrexed/cisplatin. Partial remission was achieved in the primary lesion of the lungs and BM lesion. He was further given 3 cycles of pemetrexed monotherapy and WBRT. Complete remission was further achieved in BM lesion. Conclusion: The findings of clinical trials and theoretical studies about the current pemetrexed/cisplatin in the treatment of nonsquamous NSCLC with BM are also summarized to provide a reference for the application of pemetrexed/cisplatin in nonsquamous NSCLC with BM. Whether or not pemetrexed/cisplatin is definitely effective in nonsquamous NSCLC with BM must be proven by subsequent phase III clinical trials. PMID:27512852

    2016-07-01

    Since the release of the US Preventive Services Task Force and Centers for Medicare and Medicaid Services recommendations for lung cancer screening, low-dose chest computed tomography screening has moved from the research arena to clinical practice. Lung cancer screening programs must reach beyond image acquisition and interpretation and engage in a multidisciplinary effort of clinical shared decision-making, standardization of imaging and nodule management, smoking cessation, and patient follow-up. Standardization of radiologic reports and nodule management will systematize patient care, provide quality assurance, further reduce harm, and contain health care costs. Although the National Lung Screening Trial results and eligibility criteria of a heavy smoking history are the foundation for the standard guidelines for low-dose chest computed tomography screening in the United States, currently only 27% of patients diagnosed with lung cancer would meet US lung cancer screening recommendations. Current and future efforts must be directed to better delineate those patients who would most benefit from screening and to ensure that the benefits of screening reach all socioeconomic strata and racial and ethnic minorities. Further optimization of lung cancer screening program design and patient eligibility will assure that lung cancer screening benefits will outweigh the potential risks to our patients. PMID:27306387

    Background The Da Vinci robotic system has been used to enhance the surgeon’s visualization and agility in lung cancer surgery, and thus facilitate refined dissection, knot tying and suturing. However, only a few case reports exist on performing a sleeve lobectomy with a robotic-assisted thoracoscopic surgery (RATS) technique. Here we describe our early experience performing RATS sleeve lobectomies. To our knowledge, this is the first study reporting a series of RATS sleeve lobectomies. Methods The six consecutive NSCLC patients who underwent a RATS sleeve lobectomy between November 2013 and July 2015 at the National Taiwan University Hospital were enrolled in this study. The lobectomies were all performed by the same surgeon using a three-arm robotic system with an additional utility incision made for assistance and specimen retrieval. Results Five patients were diagnosed with squamous cell carcinoma, while the sixth was diagnosed with a carcinoid tumor. The mean operation time was 436.7 [255–745] minutes. The mean postoperative intensive care unit (ICU) stay and hospital stay were 3.7 [1–11] and 11.3 [3–26] days, respectively. Two (33.3%; 2/6) morbidities were noted, including one pneumonia and one anastomosis stricture. There were no cases of mortality or of conversion to thoracotomy. Conclusions Our experience performing a RATS sleeve lobectomy in the six patients demonstrated the feasibility of RATS in complex lung cancer surgeries. The three-dimensional vision and articulated joint instruments made robotic-assisted bronchial anastomosis easier under the endoscopic setting. Our experience suggests that RATS offers specific advantages with regard to accuracy and safety when performing sleeve lobectomies.

  15. Correlation between 18F Fluorodeoxyglucose uptake and epidermal growth factor receptor mutations in advanced lung cancer

    International Nuclear Information System (INIS)

    Mutations in the epidermal growth factor receptor (EGFR)gene have been identified as potential targets for the treatment and prognostic factors for non small cell lung cancer (NSCLC). We assessed the correlation between fluorodeoxyglucose (FDG) uptake and EGFR mutations, as well as their prognostic implications. A total of 163 patients with pathologically confirmed NSCLC were enrolled (99 males and 64 females; median age, 60 years). All patients underwent FDG positron emission tomography before treatment, and genetic studies of EGFR mutations were performed. The maximum standardized uptake value (SUVmax)of the primary lung cancer was measured and normalized with regard to liver uptake. The SUVmax between the wild type and EGFR mutant groups was compared. Survival was evaluated according to SUVmax and EGFR mutation status. EGFR mutations were found in 57 patients (60.8%). The SUVmax tended to be higher in wild type than mutant tumors, but was not significantly different (11.1±5.7 vs. 9.8±4.4, P=0.103). The SUVmax was significantly lower in patients with an exon 19 mutation than in those with either an exon 21 mutation or wild type (P=0.003 and 0.009, respectively). The EGFR mutation showed prolonged overall survival (OS) compared to wild type tumors (P=0.004). There was no significant difference in survival according to SUVmax. Both OS and progression free survival of patients with a mutation in exon 19 were significant longer than in patients with wild type tumors. In patients with NSCLC, a mutation in exon 19 was associated with a lower SUVmax and is a reliable predictor for good survival

    Background The Da Vinci robotic system has been used to enhance the surgeon’s visualization and agility in lung cancer surgery, and thus facilitate refined dissection, knot tying and suturing. However, only a few case reports exist on performing a sleeve lobectomy with a robotic-assisted thoracoscopic surgery (RATS) technique. Here we describe our early experience performing RATS sleeve lobectomies. To our knowledge, this is the first study reporting a series of RATS sleeve lobectomies. Methods The six consecutive NSCLC patients who underwent a RATS sleeve lobectomy between November 2013 and July 2015 at the National Taiwan University Hospital were enrolled in this study. The lobectomies were all performed by the same surgeon using a three-arm robotic system with an additional utility incision made for assistance and specimen retrieval. Results Five patients were diagnosed with squamous cell carcinoma, while the sixth was diagnosed with a carcinoid tumor. The mean operation time was 436.7 [255–745] minutes. The mean postoperative intensive care unit (ICU) stay and hospital stay were 3.7 [1–11] and 11.3 [3–26] days, respectively. Two (33.3%; 2/6) morbidities were noted, including one pneumonia and one anastomosis stricture. There were no cases of mortality or of conversion to thoracotomy. Conclusions Our experience performing a RATS sleeve lobectomy in the six patients demonstrated the feasibility of RATS in complex lung cancer surgeries. The three-dimensional vision and articulated joint instruments made robotic-assisted bronchial anastomosis easier under the endoscopic setting. Our experience suggests that RATS offers specific advantages with regard to accuracy and safety when performing sleeve lobectomies. PMID:27499965

    Background and purpose: Studies indicate that Deep-Inspiration Breath-Hold (DIBH) is advantageous over Free-Breathing (FB) for locally advanced lung cancer radiotherapy. However, these studies were based on simplified dose calculation algorithms, potentially critical due to the heterogeneous nature...... of the lung region. Using detailed Monte-Carlo (MC) calculations, a comparative study of DIBH vs. FB was therefore designed. Material and methods: Eighteen locally advanced lung cancer patients underwent FB and DIBH CT imaging and treatment planning with the Anisotropic-Analytical-Algorithm (AAA......) for intensity-modulated-radio therapy or volumetric-modulated-arc-therapy using 66 Gy in 33 fractions. All plans were re-calculated with MC. Results: Relative to FB, the total lung volume increased 86.8% in DIBH, while the gross tumor volume decreased 14.8%. MC revealed equally under- and over...

  20. Role of erlotinib in first-line and maintenance treatment of advanced non-small-cell lung cancer

    International Nuclear Information System (INIS)

    Erlotinib hydrochloride (Tarceva®) is a member of a class of small molecule inhibitors that targets the tyrosine kinase domain of the epidermal growth factor receptor (EGFR), with anti-tumor activity in preclinical models. Erlotinib represents a new-generation of agents known as “targeted therapies” designed to act upon cancer cells by interfering with aberrant specific activated pathways needed for tumor growth, angiogenesis and cell survival. Since its approval in November 2004 for the treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC) after the failure of at least one prior chemotherapy regimen and with a view to improving patients’ outcomes and prevent symptoms, the scientific community has evaluated the potential role of erlotinib in other scenarios such as in maintenance therapy and, in first-line setting for a selected population based on biological markers of response such as mutations of the EGFR. The convenient once-a-day pill administration and the good toxicity profile of erlotinib make it a reasonable candidate for testing in this context. This report provides a review of the role of erlotinib therapy in advanced NSCLC. It summarizes current data and perspectives of erlotinib in upfront treatment and maintenance for advanced NSCLC as well as looking at candidate biomarkers of response to these new targeted-agents

    Lung cancer is the leading cause of cancer death among both men and women in the United States. It is also the leading cause of cancer death among men and the second leading cause of cancer death among women worldwide. Lung cancer rates and trends vary substantially by sex, age, race/ethnicity, socioeconomic status, and geography because of differences in historical smoking patterns. Lung cancer mortality rates in the United States are highest among males, blacks, people of lower socioeconomic status, and in the mid-South (e.g., Kentucky, Mississippi, Arkansas, and Tennessee). Globally, rates are highest in countries where smoking uptake began earliest, such as those in North America and Europe. Although rates are now decreasing in most of these countries (e.g., United States, United Kingdom, Australia), especially in men, they are increasing in countries where smoking uptake occurred later. Low- and middle-income countries now account for more than 50% of lung cancer deaths each year. This chapter reviews lung cancer incidence and mortality patterns in the United States and globally.

    Objective: The purpose of this study was to assess the curative effect and adverse reaction of preoperative induction chemotherapy with gemcitabine combined with cisplatin for locally advanced non-small cell lung cancer (NSCLC). Methods: This prospective randomized controlled trial included 115 patients with locally advanced NSCLC were randomly divided into experimental and control groups and were treated from January 2007 to January 2010. The experimental group of 63 cases was treated with two cycles of induction chemotherapy before operation, radical surgery had been performed about three weeks after completion of chemotherapy, followed by received two cycles of chemotherapy. And the control group (52 cases) was treated at first with radical surgery, then treated with four cycles of chemotherapy. Two groups of the cases received routine thoracic radiotherapy with a total dose of 45 Gy. One cycle of gemcitabine combined with cisplatin regimen in-cluded gemcitabine 1000 mg/m2 on day 1 and day 8 and cisplatin 25 mg/m2 on day 1, day 2 and day 3 by intravenous infusion, with 21 days as one cycle. The tumor recurrence was evaluated by chest CT and abdominal B-ultrasound. Efficacy and toxicity results were compared by two groups. Results: All patients were followed up for three months to two years. The surgical stage of the experimental group reduced, two-years disease-free survival and postoperative recovery in the experimental group were better than in the control group, the difference was statistical significant. Toxicity and side effect after chemotherapy were mainly bone marrow suppression and gastrointestinal reactions, other complications included thrombocytopenia, leuko-penia, anemia, liver and kidney dysfunction were no significant difference in two groups. Conclusion: Preoperative induction chemotherapy with gemcitabine combined with cisplatin for locally advanced lung cancer can reduce the surgical staging and extend the postoperative disease-free survival.

    ABSTRACT Following concurrent radio-chemotherapy or first-line chemotherapy for advanced non-small cell lung cancer(NSCLC), continuous maintenance therapy given to patients with stable disease (SD) and follow-up treatment is called consolidation therapy. Concerning NSCLC patients with a non-operable dry Stage-ⅢB (N3) disease, I.e. Contra-lateral mediastinal and hilar lymph node, or homolateral/contra-lateral scalene and Troisier sign, a 2 or 3-course of standard-dosage Taxotere consolidation therapy can be performed after concurrent radio-chemotherapy. In pursuance of evidence-based medicine (EBM), low-dose Taxoteremaintenance therapy, and biological targeted therapy of patients with appropriate symptoms are suitable for second-line therapy for moist of the Stage-ⅢB (malignant pleural effusion) and Ⅳpatients.

    Objective To evaluate the effect of accelerated hyperfractionated irradiation ( AHFI ) and conventional fractionated irradiation (CFI) for local advanced non-small cell lung cancer (NSCLC). Methods The patients of AHFI group were irradiated to large-field target volume by a daily fraction of 2Gy , and small-field target volume by a daily fraction of 1Gy with more than 6h interval. The total dose of largefield target volume was 50Gy /25Fx/5W and of small-field target volume was 75Gy /50Fx/5W. The patients in CFI group were irradiated by a daily fraction of 2Gy to the total dose of 66Gy /33Fx/6. 6W. After 3 months of radiotherapy, the tumor response rates of complete recovery ( CR ), partial recovery ( PR ), and no change ( NC ) and 1- and 2- year survival rate in the two groups were observed. Results The tumor response rates of CR, PR, NC in AHFI group and CFI group were 22.9% (8/35), 60.0% (21/35), 17.1% (6/35) and 11.4% (4/35), 51.4% (18/35), 37.2% (13/35) respectively (P>0.05). All patients were followed up 2 years or more. The 1- and 2- year survival rates in AHFI group and CFI group were 62.9% (22/35 ), 31.4 % ( 11/35) and 42.9% (15/35) , 17.1% (6/35) respectively (P0.05). Conclusion In comparison with CFI, AHFI may increase 1- and 2- year survival rate after treatment of local advanced non-small cell lung cancer, while the radio-reactions, either early or late, did not increase significantly.

    Full Text Available Background and objective Targeted therapy has become an indispensable therapy method in advanced non-small cell lung cancer (NSCLC treatment. Epithelial growth factor receptor (EGFR tyrosine kinase inhibitor (TKI can significantly prolong the survival of patients harboring EGFR gene mutation. Icotinb is China's first EGFR-TKI with independent intellectual property rights. The aim of this study is to investigate the clinical characteristics about the beneficiary of advanced NSCLC patients with EGFR Common mutation who were treated with Icotinib. Retrospectively collect the data about beneficiary [progression-free survival (PFS≥6 months] and analysis of the related risk factors for prognosis. Methods From September 1, 2011 to September 30, 2015, 231 cases of advanced NSCLC beneficiary with EGFR common mutation were enrolled for treatment with icotinib in Zhejiang Cancer Hospital. Results The one year benefit rate was 67.9% in the group treated with Icotinib as first line, and in the groupas second line or above was 53.6%, which is statisticallysignificant. The two years benefit rate was 18.7% and 9.3%, respectively. The median PFS of first line group and the second line or above was 16.7 and 12.4 months, respectively. The presence of brain metastasis (P=0.010, Prior chemotherapy (P=0.001, Eastern Cooperative Oncology Group (ECOG score (P=0.001 were the main factors influencing the prognosis. The most common adverse were skin rashes (51 cases, 22.1% and diarrhea (27 cases, 11.7%. Conclusion Icotinib offers long-term clinical benefit and good tolerance for advanced NSCLC harboring EGFR gene mutation.

  19. The relationship between glasgow prognostic score and serum tumor markers in patients with advanced non-small cell lung cancer

    International Nuclear Information System (INIS)

    Glasgow Prognostic Score (GPS) has been reported as a powerful prognostic tool for patients with advanced non–small cell lung cancer (NSCLC). The aim of this study was to assess the relationship between GPS and prognosis related tumor markers in patients with advanced NSCLC. We included 138 advanced NSCLC patients and twenty healthy controls in the study. GPS was calculated by combined serum C-reactive protein (CRP) and albumin. Three serum tumor markers, which included cytokeratin 19 fragment antigen 21-1 (CYFRA21–1), carcinoembryonic antigen (CEA) and tissue polypeptide specific antigen (TPS), were detected by enzyme-linked immunosorbent assay (ELISA). GPS and tumor markers were all assessed before chemotherapy. All patients received at least 2 courses of cisplatin-based chemotherapy. After that, 2 to 5 years follow-up was conducted. Median levels of CYFRA21–1 were 1.5 ng/ml (0.1–3.1 ng/ml) in healthy controls, and 4.6 ng/ml (0.7–35.2 ng/ml) in GPS 0 advanced NSCLC, 11.2 ng/ml (0.4–89.2) ng/ml in GPS 1 advanced NSCLC, and 15.7 ng/ml (2.9–134.6 ng/ml) in GPS 2 advanced NSCLC, respectively. Median levels of CYFRA21-1 were higher in NSCLC patients than in healthy controls, and CYFRA21-1 increased gradually according to GPS category in NSCLC patients (P < 0.05). Similar results were found for median levels of CEA and TPS in healthy controls and NSCLC patients (P < 0.05). In NSCLC patients, positive correlations were found between CYFRA21-1 and GPS, CEA and GPS, TPS and GPS. The Spearman’s rank correlation coefficient were 0.67 (P < 0.05), 0.61 (P < 0.05) and 0.55 (P < 0.05), respectively. Survival analyses showed GPS was an independent prognostic factor for advanced NSCLC. CYFRA21-1(>3.3 ng/ml) and TPS (>80 U/l) were related with the prognosis of advanced NSCLC by univariate analyses, but multivariate analyses showed CYFRA21-1, TPS and CEA were not the independent prognostic factors for advanced NSCLC. Our results showed GPS were positive correlated

    Kim, Hyea Young [Dept. of Radiology, Center for Lung Cancer, National Cancer Center, Goyang (Korea, Republic of)

    2015-09-15

    Lung cancer is the leading cause of cancer deaths worldwide as well as in Korea. A recent National Lung Screening Trial in U.S. revealed that low-dose CT (LDCT) screening reduced lung cancer specific mortality by 20% in high risk individuals as compared to chest radiograph screening. Based on this evidence, several expert societies in U.S. and Korean multisociety collaborative committee developed guidelines for recommendation of lung cancer screening using annual LDCT in high risk populations. In most of the societies high risk groups are defined as persons aged 55 to 74 years, who are current smokers with history of smoking of more than 30 packs per year or ex-smokers, who quit smoking up to 15 or more years ago. The benefits of LDCT screening are modestly higher than the harms in high risk individuals. The harms included a high rate of false-positive findings, over-diagnosis and radiation-related deaths. Invasive diagnostic procedure due to false positive findings may lead to complications. LDCT should be performed in qualified hospitals and interpreted by expert radiologists. Recently, the American College of Radiology released the current version of Lung cancer CT screening Reporting and Data Systems. Education and actions to stop smoking must be offered to current smokers.

Stages: 74 had III A and 215 III B stage disease. Among the 121 patients treated with combined modality, 24 were treated with concurrent chemoradiotherapy, 78 radiotherapy after chemotherapy(C + R), and 19 radiotherapy followed by chemotherapy(R + C). In patients treated by concurrent chemoradiotherapy or C + R, 38 received consolidation chemotherapy after induction treatment. Results: The 1-, 3-, 5-year overall survival, and the median survival were: 45% , 16% , 8%, and 16.2 months for all patients; 57%, 27%, 11%, and 21.7 months for stage IIIA; 41%, 12%, 7%, and 15.3 months for IIIB. By logrank test, clinical stage, KPS performance, tumor volume, hemoglobin level before treatment, consolidation chemotherapy, radiation dose, and response to treatment showed statistically dramatic impact on overall survival. The overall survival rate and median survival time were slightly higher in the combined group than in the radiotherapy alone group, but the difference is statistically insignificant. In Cox multivariable regression, stage and consolidation chemotherapy were independent prognostic factors; KPS performance, radiation dose, and response to treatment were at the margin of statistical significance. Esophagitis and pneumonitis of Grade II or higher were 24% and 8%, respectively. Failure sites included in the thorax(41%), outside of thorax(48%), and both in and outside the thorax(11%). There was no difference between the

    PurposeTo verify whether microwave ablation (MWA) used as a local control treatment had an improved outcome regarding advanced non-small cell lung cancer (NSCLC) when combined with chemotherapy.MethodsThirty-nine patients with histologically verified advanced NSCLC and at least one measurable site other than the ablative sites were enrolled. Primary tumors underwent MWA followed by platinum-based doublet chemotherapy. Modified response evaluation criteria in solid tumors (mRECIST) and RECIST were used to evaluate therapeutic response. Complications were assessed using the National Cancer Institute Common Toxicity Criteria (version 3.0).ResultsMWA was administered to 39 tumors in 39 patients. The mean and median diameters of the primary tumor were 3.84 cm and 3.30 cm, respectively, with a range of 1.00–9.00 cm. Thirty-three (84.6 %) patients achieved a partial response. No correlation was found between MWA efficacy and clinicopathologic characteristics. For chemotherapy, 11 patients (28.2 %) achieved a partial response, 18 (46.2 %) showed stable disease, and 10 (25.6 %) had progressive disease. The overall objective response rate and disease control rate were 28.2 and 74.4 %, respectively. The median progression-free survival time was 8.7 months (95 % CI 5.5–11.9). The median overall survival time was 21.3 months (95 % CI 17.0–25.4). Complications were observed in 22 (56.4 %) patients, and grade 3 adverse events were observed in 3 (7.9 %) patients.ConclusionsPatients with advanced NSCLC could benefit from MWA in combination with chemotherapy. Complications associated with MWA were common but tolerable.

    2014-06-01

    Full Text Available Radiation dose in the setting of chemo-radiation for locally advanced non-small cell lung cancer (NSCLC has been historically limited by the risk of normal tissue toxicity and this has been hypothesized to correlate with the poor results in regard to local tumor recurrences. Dose escalation, as a means to improve local control, with concurrent chemotherapy has been shown to be feasible with three-dimensional conformal radiotherapy in early phase studies with good clinical outcome. However, the potential superiority of moderate dose escalation to 74 Gy has not been shown in phase III randomized studies. In this review, the limitations in target volume definition in previous studies; and the factors that may be critical to safe dose escalation in the treatment of locally advanced NSCLC, such as respiratory motion management, image guidance, intensity modulation, FDG-PET incorporation in the treatment planning process, and adaptive radiotherapy, are discussed. These factors, along with novel treatment approaches that have emerged in recent years, are proposed to warrant further investigation in future trials in a more comprehensive and integrated fashion.

    Full Text Available Background/Aim. As therapy for locally advanced nonsmall cell lung carcinoma (NSCLC improves, brain metastases (BM still remain a great problem. The aim of the study was to analyze risk factors for BM in patients with locally advanced NSCLC after chemoradiation therapy. Methods. Records for 150 patients with non-resectable stage IIIA/IIIB NSCLC treated with combined chemoradiation therapy were analyzed. All of them had negative brain metastases imaging result before the treatment. Incidence of BM was examined in relation to age, sex, histological type, stage, performance status scale of wellbeing of cancer patients, weight loss, chemotherapy regimen and chemotherapy timing. Results. One- and 2-year incidence rates of BM were 19 and 31%, respectively. Among pretreatment parameters, stage IIIB was associated with a higher risk of BM (p < 0.004 vs stage IIIA. Histologically, the patients with nonsquamous tumors had an exceptionally high 2-year BM risk rate of 32% (p < 0.02. Examining treatment-related parameters, 1-year and 2-year actuarial risk of BM were 27 and 39%, respectively, in the patients receiving chemotherapy before radiotherapy and 15 and 20%, respectively, when radiotherapy was not delayed (p < 0.03. On multivariate analysis, timing of chemotherapy (p < 0.05 and stage IIIA vs IIIB (p < 0.01 remained statistically significant. Conclusion. Patients with IIIB stage, nonsquamous NSCLC, particularly those receiving sequential chemotherapy, had significantly high BM rates.

    2016-02-01

    Full Text Available BACKGROUND: Recent clinical trial results have suggested that programmed cell death ligand 1 (PD-L1 expression measured by immunohistochemistry may predict response to anti–programmed cell death 1 (PD-1 therapy. Results on the association between PD-L1 expression and survival among patients with advanced non–small cell lung cancer (NSCLC treated with chemotherapy are inconsistent. MATERIAL AND METHODS: We evaluated the relationship between PD-L1 expression and overall survival (OS among 204 patients with advanced NSCLC treated at Aarhus University Hospital, Aarhus, Denmark, from 2007 to 2012. PD-L1 expression was measured using a prototype immunohistochemistry assay with the anti–PD-L1 22C3 antibody (Merck. PD-L1 strong positivity and weak positivity were defined to be traceable to the clinical trial version of the assay. RESULTS: Twenty-five percent of patients had PD-L1 strong-positive tumors, and 50% had PD-L1 weak-positive tumors. No statistically significant association was found between PD-L1 expression and survival; adjusted hazard ratio of 1.34 (95% confidence interval, 0.88-2.03; median OS, 9.0 months for the PD-L1 strong-positive group and 1.07 (0.74-1.55; median OS, 9.8 months for the PD-L1 weak-positive group compared with the PD-L1–negative group (median OS, 7.5 months. No association was seen between PD-L1 expression and OS when PD-L1 expression levels were stratified by median or tertiles. CONCLUSIONS: In concordance with previous studies, we found PD-L1 measured by immunohistochemistry to be frequently expressed in patients with advanced NSCLC. However, PD-L1 expression is not a strong prognostic marker in patients with advanced NSCLC treated with chemotherapy.

    Abstract Background: Anti-PD-1/PD-L1 antibody therapy is a promising clinical treatment for nonsmall-cell lung cancer (NSCLC). However, whether anti-PD-1/PD-L1 antibody therapy can provide added benefits for heavily pretreated patients with advanced NSCLC and whether the efficacy of anti-PD-1/PD-L1 antibody therapy relates to the tumor PD-L1 expression level remain controversial. Thus, this meta-analysis evaluated the efficacy and safety of anti-PD-1/PD-L1 antibody therapy for pretreated patients with advanced NSCLC. Methods: Randomized clinical trials were retrieved by searching the PubMed, EMBASE, ASCO meeting abstract, clinicaltrial.gov, and Cochrane library databases. The pooled hazard ratios (HRs) for overall survival (OS) and progression-free survival (PFS), and odds ratios for the overall response rate and adverse events (AEs) were calculated by STATA software. Results: Three randomized clinical trials involving 1141 pretreated patients with advanced NSCLC were included. These trials all compared the efficacy and safety of anti-PD-1/PD-L1 antibodies (nivolumab and MPDL3280A) with docetaxel. The results suggested that, for all patients, anti-PD-1/PD-L1 therapy could acquire a greater overall response (odds ratio = 1.50, 95% CI: 1.08–2.07, P = 0.015, P for heterogeneity [Ph] = 0.620) and longer OS (HR = 0.71, 95% CI: 0.61–0.81, P AEs of anti-PD-1/PD-L1 therapy were significantly lower than that of docetaxel. However, the risks of pneumonitis and hypothyroidism were significantly higher. Conclusion: Anti-PD-1/PD-L1 antibody therapy may significantly improve the outcomes for pretreated advanced NSCLC patients, with a better safety profile than docetaxel. PMID:27583876

    Increasing evidence has revealed that IGF signalling plays a key role in cellular proliferation, survival, differentiation and senescence. Dysregulation of this signalling pathway is related to the development and progression of many human diseases, including cancer, diabetes and atherosclerosis. Insulin-like growth factor binding protein-2 (IGFBP-2) is reported to be a modulator of the action of insulin-like growth factors (IGFs), whereas IGF-independent effects of IGFBP-2 on cellular proliferation, apoptosis, and mobility have been revealed not only during the embryonic state but also in the pathological state of cancer. IGFBP-2 is involved in the genesis and progress of various malignancies including lung cancer. Recent ifndings show in many pre-clinical trials that IGFBP-2 may contribute to the transformation and progression of lung cancer. These studies suggest that IGFBP-2 may be a potential therapeutic target for lung cancer. In this review, we provide an overview on IGFBP-2, review corresponding studies investigating the role of IGFBP-2 as a cancer target in multiple tumors and discuss its possible mechanism in lung cancer.

    Purpose: Four-dimensional cone beam CT ventilation imaging (4D-CBCT VI) is a novel functional lung imaging modality requiring validation. We hypothesize that 4D-CBCT VI satisfies a necessary condition for validity: that intrafraction variations (e.g. due to poor 4D-CBCT image quality) are substantially different to interfraction variations (e.g. due to changes in underlying function). We perform the first comparison of intrafraction (pre/post fraction) and interfraction (week-to-week) 4D-CBCT VIs for locally advanced non small cell lung cancer (LA NSCLC) patients undergoing radiation therapy. Methods: A total of 215 4D-CBCT scans were acquired for 19 LA NSCLC patients over 4-6 weeks of radiation therapy, including 75 pairs of pre-/post-fraction scans on the same day. 4D-CBCT VIs were obtained by applying state-of-the-art, B-spline deformable image registration to obtain the Jacobian determinant of deformation between the end-exhale and end-inhale phases. All VIs were deformably registered to the corresponding first day scan, normalized between the 10th and 90th percentile values and cropped to the ipsilateral lung only. Intrafraction variations were assessed by computing the mean and standard deviation of voxel-wise differences between all same-day pairs of pre-/post-fraction VIs. Interfraction differences were computed between first-day VIs and treatment weeks 2, 4 and 6 for all 19 patients. We tested the hypothesis by comparing cumulative distribution functions (CDFs) of intrafraction and interfraction ventilation differences using two-sided Kolmogorov-Smirnov goodness-of-fit tests. Results: The (mean ± std. dev.) of intrafraction differences was (−0.007 ± 0.079). Interfraction differences for weeks 2, 4 and 6 were (−0.035 ± 0.103), (−0.006 ± 0.094) and (−0.019 ± 0.127) respectively. For week 2, the changes in CDFs for intrafraction and interfraction differences approached statistical significance (p=0.099). Conclusion: We have shown that 4D-CBCT VI

    Objectives Maintenance therapy is a standard therapeutic strategy in non-squamous non-small-cell lung cancer. However, there is no consensus regarding the benefit of maintenance therapy for patients with squamous cell lung cancer. We assessed maintenance therapy with S-1, an oral fluoropyrimidine agent, following induction therapy with carboplatin and S-1 in patients with squamous cell lung cancer. Methods In this phase II trial, chemotherapy-naïve patients with squamous cell lung cancer were enrolled to induction therapy with four cycles of carboplatin (at an area under the curve of 5 on day 1) and S-1 (80 mg/m(2)/day on days 1-14) in a 28-day cycle. Patients who achieved disease control after induction therapy received maintenance therapy with S-1 in a 21-day cycle until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival after administration of maintenance therapy. Results Fifty-one patients were enrolled in the study. The median progression-free survival from the start of maintenance therapy was 3.0 months (95 % confidence interval, 2.5-3.5). The most common toxicities associated with maintenance therapy were anemia, thrombocytopenia, and fatigue, but they were not severe. Conclusion S-1 maintenance therapy might be a feasible treatment option in patients with squamous cell lung cancer.

    To analyze the response, toxicity, patterns of failure and survival rate of patients with locally advanced non-small cell lung cancer who were treated with concurrent chemoradiotherapy with weekly paclitaxel. Twenty-three patients with locally advanced non-small cell lung cancer patients who received radical chemoradiotherapy from October 1999 to September 2004 were included in this retrospective study. Patients received total 55.4 {approx} 64.8 (median 64.8) Gy (daily 1.8 Gy per fraction, 5 days per weeks) over 7 {approx} 8 weeks. 50 or 60 mg/m{sup 2} of paclitaxel was administered on day 1, 8, 15, 22, 29 and 36 of radiotherapy. Four weeks after the concurrent chemoradiotherapy, three cycles of consolidation chemotherapy consisted of paclitaxel 135 mg/m{sup 2} and cisplatin 75 mg/m{sup 2} was administered every 3 weeks. Of the 23 patients, 3 patients refused to receive the treatment during the concurrent chemoradiotherapy. One patient died of bacterial pneumonia during the concurrent chemoradiotherapy. Grade 2 radiation esophagitis was observed in 4 patients (17%). Sixteen patients received consolidation chemotherapy. During the consolidation chemotherapy, 8 patients (50%) experienced grade 3 or 4 neutropenia and one of those patients died of neutropenic sepsis. Overall response rate for 20 evaluable patients was 90% including 4 complete responses (20%) and 14 partial responses (70%). Among 18 responders, 9 had local failure, 3 had local and distant failure and 2 had distant failure only. Median progression-free survival time was 9.5 months and 2-year progression-free survival rate was 19%. Eleven patients received second-line or third-line chemotherapy after the treatment failure. The median overall survival time was 21 months. 2-year and 5-year survival rate were 43% and 33%, respectively. Age, performance status, tumor size were significant prognostic factors for progression-free survival. Concurrent chemoradiotherapy with weekly paclitaxel revealed high

  4. Phase II study. Concurrent chemotherapy and radiotherapy with nitroglycerin in locally advanced non-small cell lung cancer

    International Nuclear Information System (INIS)

    Background: Nitroglycerin, a nitric oxide donor agent, reduces the expression of hypoxia-inducible factor-1α (HIF-1α) and could be a normalizer of the tumor microenvironment. Both factors are associated with chemo-radio-resistance. The aim of this study was to determine the safety profile and efficacy of nitroglycerin administration with chemo-radiotherapy in patients with locally advanced non-small cell lung cancer (NSCLC). Methods: This is a phase II trial of locally advanced NSCLC patients treated with cisplatin and vinorelbine plus concurrent nitroglycerin with radiotherapy. A 25-mg NTG patch was administered to the patients for 5 days (1 day before and 4 days after chemotherapy induction and consolidation) and all day during chemo-radiotherapy. VEGF plasmatic level was determined before and after two cycles of chemotherapy. Results: Thirty-five patients were enrolled in this trial. Sixty-three percent of patients achieved an overall response after induction of chemotherapy, and 75% achieved an overall response after chemo-radiotherapy. The median progression-free survival was 13.5 months (95% CI, 8.8–18.2), and the median overall survival was 26.9 months (95% CI, 15.3–38.5). Reduction of VEGF level was associated with better OS. The toxicity profile related to nitroglycerin included headache (20%) and hypotension (2.9%). Conclusions: The addition of nitroglycerin to induction chemotherapy and concurrent chemoradiotherapy in patients with locally advanced NSCLC has an acceptable toxicity profile and supports the possibility to add nitroglycerin to chemotherapy and radiotherapy. A randomized trial is warranted to confirm these findings

    Bone metastases often appear in advanced stages of lung cancer. They are the result of modulation of bone metabolism by tumor cells that migrated into bone microenvironment and degraded bone organic matrix. Measurement of C-terminal telopeptide of type I collagen (ICTP) in the serum of subjects with lung cancer with and without bone metastases and healthy population is the way to explore bone resorption. In 343 subjects included in this research ICTP level was significantly higher...

    Purpose: Local tumor control and outcome remain poor in patients with advanced non-small-cell lung cancer (NSCLC) treated by external beam radiotherapy. We investigated the therapeutic gain of individualized dose prescription with dose escalation based on normal tissue dose constraints for various hypofractionation schemes delivered with intensity-modulated radiation therapy. Methods and Materials: For 38 Stage III NSCLC patients, the dose level of an existing curative treatment plan with standard fractionation (66 Gy) was rescaled based on dose constraints for the lung, spinal cord, esophagus, brachial plexus, and heart. The effect on tumor total dose (TTD) and biologic tumor effective dose in 2-Gy fractions (TED) corrected for overall treatment time (OTT) was compared for isotoxic and maximally tolerable schemes given in 15, 20, and 33 fractions. Rescaling was accomplished by altering the dose per fraction and/or the number of fractions while keeping the relative dose distribution of the original treatment plan. Results: For 30 of the 38 patients, dose escalation by individualized hypofractionation yielded therapeutic gain. For the maximally tolerable dose scheme in 33 fractions (MTD{sub 33}), individualized dose escalation resulted in a 2.5-21% gain in TTD. In the isotoxic schemes, the number of fractions could be reduced with a marginal increase in TED. For the maximally tolerable dose schemes, the TED could be escalated up to 36.6%, and for all patients beyond the level of the isotoxic and the MTD{sub 33} schemes (range, 3.3-36.6%). Reduction of the OTT contributed to the therapeutic gain of the shortened schemes. For the maximally tolerable schemes, the maximum esophageal dose was the dominant dose-limiting constraint in most patients. Conclusions: This modeling study showed that individualized dose prescription for hypofractionation in NSCLC radiotherapy, based on scaling of existing treatment plans up to normal tissue dose constraints, enables dose

  13. Respiratory motion variability of primary tumors and lymph nodes during radiotherapy of locally advanced non-small-cell lung cancers

    International Nuclear Information System (INIS)

    The need for target adjustment due to respiratory motion variation and the value of carina as a motion surrogate is evaluated for locally advanced non-small-cell lung cancer. Using weekly 4D CTs (with audio-visual biofeedback) of 12 patients, respiratory motion variation of primary tumors (PT), lymph nodes (LN) and carina (C) were determined. Mean (SD) 3D respiratory motion ranges of PT, LN and C were 4 (3), 5 (3) and 5 (3) mm. PT and LN (p = 0.003), and LN and C motion range were correlated (p = 0.03). Only 20 %/5 % of all scans had variations >3 mm/5 mm. Large respiratory motion range on the initial scan was associated with larger during-treatment variations for PT (p = 0.03) and LN (p = 0.001). Mean (SD) 3D relative displacements of PT-C, LN-C and PT-LN were each 6 (2) mm. Variations of displacements >3 mm/5 mm were observed in 28 %/6 % of scans for PT-LN, 20 %/9 % for PT-C, and 20 %/8 % for LN-C. Motion reassessment is recommended in patients with large initial motion range. Relative motion-related displacements between PT and LN were larger than PT and LN motion alone. Both PT and C appear to be comparable surrogates for LN respiratory motion

    Objective: To assess the clinical value of 125I seeds implantation combined with the bronchial arterial infusion chemotherapy in treating advanced lung cancer. Methods: 125I seeds implantation combined with the bronchial arterial infusion chemotherapy was performed in 30 patients with advanced lung cancer. About 3 -70 seeds of 125I (6711 type, 0.7 mCi / seed) were delivered in each patient. In all patients bronchial arterial infusion chemotherapy was carried out at the time of 7 days before the implantation and 30 and 60 days after the implantation. The results and complications were observed. The clinical data were retrospectively analyzed. The therapeutic efficacy was evaluated according to RECIST standards. Results: A total of 40 lesions were detected in all 30 patients and 125I seeds were successfully embedded in all lesions. No procedure-related complications occurred. All patients were followed up for 2 -24 months. The two-year survival rate was 86.6% (26 / 30). Therapeutic evaluation made at four months after the treatment showed that CR, PR, NC and PD was seen in 26, 10, 2 and 2 lesions respectively,with a total effective rate of 90%. Conclusion: 125I seeds implantation combined with the bronchial arterial infusion chemotherapy is a safe and effective therapy for advanced lung cancer with excellent clinical results. (authors)

    Muscle dysfunction and wasting are predictors of mortality in advanced COPD and malignancies. Redox imbalance and enhanced protein catabolism are underlying mechanisms in COPD. We hypothesized that the expression profile of several biological markers share similarities in patients with cachexia associated with either COPD or lung cancer (LC). In vastus lateralis of cachectic patients with either LC (n=10) or advanced COPD (n=16) and healthy controls (n=10), markers of redox balance, inflammation, proteolysis, autophagy, signaling pathways, mitochondrial function, muscle structure, and sarcomere damage were measured using laboratory and light and electron microscopy techniques. Systemic redox balance and inflammation were also determined. All subjects were clinically evaluated. Compared to controls, in both cachectic groups of patients, a similar expression profile of different biological markers was observed in their muscles: increased levels of muscle protein oxidation and ubiquitination (p<0.05, both), which positively correlated (r=0.888), redox-sensitive signaling pathways (NF-κB and FoxO) were activated (p<0.05, all), fast-twitch fiber sizes were atrophied, muscle structural abnormalities and sarcomere disruptions were significantly greater (p<0.05, both). Structural and functional protein levels were lower in muscles of both cachectic patient groups than in controls (p<0.05, all). However, levels of autophagy markers including ultrastructural autophagosome counts were increased only in muscles of cachectic COPD patients (p<0.05). Systemic oxidative stress and inflammation levels were also increased in both patient groups compared to controls (p<0.005, both). Oxidative stress and redox-sensitive signaling pathways are likely to contribute to the etiology of muscle wasting and sarcomere disruption in patients with respiratory cachexia: LC and COPD.

  4. Molecular biology of the lung cancer

    International Nuclear Information System (INIS)

    Background. Lung cancer is one of the most common malignant diseases and leading cause of cancer death worldwide. The advances in molecular biology and genetics, including the modern microarray technology and rapid sequencing techniques, have enabled a remarkable progress into elucidating the lung cancer ethiopathogenesis. Numerous studies suggest that more than 20 different genetic and epigenetic alterations are accumulating during the pathogenesis of clinically evident pulmonary cancers as a clonal, multistep process. Thus far, the most investigated alterations are the inactivational mutations and losses of tumour suppressor genes and the overexpression of growth-promoting oncogenes. More recently, the acquired epigenetic inactivation of tumour suppressor genes by promoter hypermethylation has been recognized. The early clonal genetic abnormalities that occur in preneoplastic bronchial epithelium damaged by smoking or other carcinogenes are being identified. The molecular distinctions between small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC), as well as between tumors with different clinical outcomes have been described. These investigations lead to the hallmarks of lung cancer. Conclusions. It is realistic to expect that the molecular and cell culture-based investigations will lead to discoveries of new clinical applications with the potential to provide new avenues for early diagnosis, risk assessment, prevention, and most important, new more effective treatment approaches for the lung cancer patients.

  7. Cholinergic Targets in Lung Cancer.

    Science.gov (United States)

    Spindel, Eliot R

    2016-01-01

    Lung cancers express an autocrine cholinergic loop in which secreted acetylcholine can stimulate tumor growth through both nicotinic and muscarinic receptors. Because activation of mAChR and nAChR stimulates growth; tumor growth can be stimulated by both locally synthesized acetylcholine as well as acetylcholine from distal sources and from nicotine in the high percentage of lung cancer patients who are smokers. The stimulation of lung cancer growth by cholinergic agonists offers many potential new targets for lung cancer therapy. Cholinergic signaling can be targeted at the level of choline transport; acetylcholine synthesis, secretion and degradation; and nicotinic and muscarinic receptors. In addition, the newly describe family of ly-6 allosteric modulators of nicotinic signaling such as lynx1 and lynx2 offers yet another new approach to novel lung cancer therapeutics. Each of these targets has their potential advantages and disadvantages for the development of new lung cancer therapies which are discussed in this review. PMID:26818857

    Objective: To assess the short-term efficacy of bronchial artery infusion (BAI) of Gemcitabine (GEM) plus Cisplatin (DDP) combined with systemic chemotherapy of GEM for advanced non-small cell lung cancer (NSCLC). Methods: A total of 60 patients with pathologically proved primary NSCLC were randomly selected. BAI with GEM (1000 mg/m2) and DDP (DDP 50 mg/m2) was performed on the first day, and systemic chemotherapy of GEM (1000 mg/m2) was carried out on the eighth day. The clinical results were analyzed. Results: Of the 60 patients, CR, PR, SD and PD were obtained in 3, 35, 17 and 5, respectively, with an overall effective rate of 63%. Twenty-two patients had adenocarcinoma and the effective rate of them was 45%. Thirty-eight patients had squamous cell carcinoma and their effective rate was 74%. The difference in the effective rate between the above two pathologic types was significant (P<0.05). Central type lung cancer was seen in 37 cases, their effective rate was 73%. The peripheral type lung cancer was seen in the remaining 23 patients and the effective rate was 48%. The difference in the effective rate was statistically significant between the central type and the peripheral type (P<0.05). Conclusion: The combination of bronchial artery infusion with systemic chemotherapy by using GP plan is an effective, feasible approach in the treatment of advanced non-small cell lung cancer. The short-term efficacy of the treatment bears a close relationship to the anatomical location and pathological type of the cancer. (authors)

    Background. The safety of using a cutting needle when performing a core-needle biopsy is of major concern, in particular for small lung tumors or tumors near the hilum. Purpose. To investigate the usefulness of CT-guided fine needle aspiration biopsy (FNAB) of the lung in obtaining tumor tissue for epidermal growth factor receptor (EGFR) mutation analysis in advanced lung cancer patients. Material and Methods. Forty-three patients with stage IIIB-IV lung cancer were enrolled. In all patients, CT-guided FNAB was performed using an 18-gauge or 20-gauge Chiba aspiration needle for histology diagnosis and EGFR mutation analysis. Complications associated with CT-guided FNAB were observed, and the specimen mutational assessments were recorded. Results. The obtained tumor samples ranged from 0.5-1.5 cm in length and were adequate for histological and DNA analyses in all patients. No patient had a pneumothorax or hemoptysis. Minor needle tract bleeding appeared in eight patients. Mutation analysis was satisfactorily demonstrated in 23 mutations and 20 non-mutations. Ten and 13 mutations were identified by 18-gauge and 20-gauge needle biopsies, respectively. EFGR mutations, including 12 cases of EGFR exon 19 deletion and 11 cases of exon 21 point mutation, were present in 21 patients with adenocarcinomas, one with squamous cell carcinoma, and one with undifferentiated carcinoma. Conclusion. CT-guided FNAB is a feasible and safe technique for obtaining lung tumor tissues for EGFR gene mutation analysis

    Full Text Available Neha Gupta, Hassan Hatoum, Grace K DyDepartment of Medicine, Roswell Park Cancer Institute, Buffalo, NY, USAAbstract: Lung cancer is the leading cause of cancer mortality worldwide in both men and women. Non-small-cell lung cancer (NSCLC is the most common type of lung cancer, accounting for more than 80% of cases. Paclitaxel has a broad spectrum of activity against various malignancies, including NSCLC. Paclitaxel is poorly soluble in water and thus, until recently, its commercially available preparations contained a non-ionic solvent Cremophor EL®. Cremophor EL® improves the solubility of paclitaxel and allows its intravenous administration. However, certain side-effects associated with paclitaxel, such as hypersensitivity reactions, myelosuppression, and peripheral neuropathy, are known to be worsened by Cremophor®. Nanoparticle albumin-bound paclitaxel ([nab-paclitaxel] ABRAXANE® ABI-007 is a new generation formulation of paclitaxel that obviates the need for Cremophor®, resulting in a safer and faster infusion without requiring the use of premedications to avoid hypersensitivity. Albumin-binding receptor-mediated delivery and lack of sequestering Cremophor® micelles allow higher intratumoral concentration of pharmacologically active paclitaxel. Multiple clinical trials have demonstrated a superior tolerability profile of nab-paclitaxel in comparison to solvent-bound paclitaxel (sb-paclitaxel. A recent Phase III trial compared the effects of weekly nab-paclitaxel in combination with carboplatin versus sb-paclitaxel in combination with carboplatin given every 3 weeks for first line treatment of NSCLC. This trial highlights the weekly nab-paclitaxel combination as an alternate treatment option for NSCLC, with higher response rate in squamous cell NSCLC and longer survival in elderly patients. This review will focus on the properties of nab-paclitaxel and its use in the first line treatment of NSCLC.Keywords: ABI-007, Abraxane, nab

  17. Daily etoposide and cisplatin during thoracic radiotherapy for patients with locally advanced non-small cell lung cancer

    International Nuclear Information System (INIS)

    Purpose: A phase I/II trial was performed to investigate the toxicity and potential efficacy of delivering two radiosensitizing chemotherapeutic agents (cisplatin and etoposide) on a daily basis during twice daily thoracic radiotherapy for patients with locally advanced non-small cell lung cancer. Methods: Patients were eligible for this trial if they had unresectable or incompletely resected biopsy-proven stage IIIA or IIIB non-small cell lung carcinoma. However, patients with contralateral hilar or supraclavicular disease were excluded. Patients were required to have an ECOG performance status of 0-2 and ≤10% weight loss during the preceding three months. Thoracic radiation treatment (TRT) was delivered as accelerated hyperfractionated TRT with 150 cGy given twice daily beginning on a Monday. Patients received a two-week break between two courses of 3000 cGy (total dose:6000cGy). Patients received etoposide (25 mg/m2 po) on days 1-12 and cisplatin (3 mg/m2 IV) on days 1-5 and 8-12 of each course of TRT. Two weeks following the completion of TRT patients began two cycles (q 28d) of etoposide (25 mg/m2, po, d1-21) and cisplatin (50 mg/m2 IV, d1). Patients were seen in followup at 2 months following the completion of therapy and subsequently at 3 month intervals for the first year. Results: Seventeen patients were entered on the trial and the median followup was 11 months. Of the 17 patients, 13 had evaluable disease and 4 had measurable disease; 16 were deemed unresectable and one had an incomplete resection; 6 had squamous cell carcinomas and 11 had non-squamous cell carcinomas; 5 had primary tumors greater than 6 cm, 9 were 3-6 cm and 3 were <3 cm; 14 had less than 5% weight loss and 3 had 5-10% weight loss; 9 had stage IIIA disease and 8 had IIIB disease. The most common hematologic toxicity was leukopenias: 4 patients had grade 3 and 1 had grade 4 toxicity. No grade 3 or greater thrombocytopenia was observed. There were 6 grade 3 nonhematologic toxicities

    Full Text Available Background and objective The epidermal growth factor receptor tyrosine kinase inhibitor (EGFRTKI shows favorable antitumor activity against chemorefractory non-small cell lung cancer (NSCLC. However, patients with advanced NSCLC have limited treatment options available if they are refractory to EGFR-TKI. To study the influence of the retreatment EGFR-TKI after failure of first-line TKI, we carried out this retrospective study. Methods Total 71 patients were analyzed who experienced treatment failure from their initial use of EGFR-TKI. After a period of time, they were retreated with TKI as tumor progression was observed. Results Of the 71 patients who received retreatment TKI, it was observed in 7% in partial response (PR, 36.6% in stable disease (SD, 56.3% in progressive disease (PD. Disease control rate (DCR was 43.7%. Twenty-six (36.6% patients were well controlled by retreatment with TKI monotherapy for not less than 3 months. Five (7.0% patients had partial response. Exon 21 mutation, PFS not less than 6 months during initial treatment TKI, and the interval not less than 3 months between initial treatment, and retreatment with TKI was associated with a good progression free survival based on univariate COX analysis (P=0.034; P=0.013; P=0.046. Conclusion It has been shown the possibility that retreatment with TKI might be useful when (1 Exon 21 has active mutation, (2 initial treatment shows a favorable PFS (≥ 6 months, and (3 there has been a period of time (≥3 months following the termination of the initial TKI treatment.

    Background: [{sup 18}F]fluorodeoxyglucose positron emission tomography (FDG-PET) imaging has been employed as a non-invasive diagnostic tool for malignant tumors. Total lesion glycolysis (TLG) on FDG-PET is calculated by multiplying the mean standardized uptake value (SUVmean) by the tumor volume. Unlike the maximum standardized uptake value (SUVmax), which represents the point of greatest metabolic activity within tumors, TLG has been suggested to reflect global metabolic activity in whole tumors. Methods: We retrospectively examined whether or not FDG-PET measurements, including SUVmean, SUVmax, and TLG, could predict progression-free survival (PFS) or overall survival (OS) in patients with non-small cell lung cancer (NSCLC) receiving chemotherapy. Results: This study involved 81 consecutive patients with NSCLC who received chemotherapy. All of the patients underwent FDG-PET examination before treatment. SUVmean, SUVmax, and TLG on FDG-PET were significantly associated with gender, smoking status, and tumor histology. With adjustment for several other variables, Cox regression analysis showed that TLG was significantly prognostic for both PFS [hazard ratio = 2.34; 95% confidence interval, 1.18–4.64; P = 0.015] and OS (hazard ratio = 2.80; 95% confidence interval, 1.12–6.96; P = 0.003), whereas SUVmean and SUVmax had no significant association with PFS (P = 0.693 and P = 0.322, respectively) or OS (P = 0.587 and P = 0.214, respectively). Conclusions: Our findings suggest that TLG may be more useful than SUVmean and SUVmax for predicting PFS and OS in NSCLC patients receiving chemotherapy. The TLG measurement on FDG-PET imaging could be routinely recommended to advanced NSCLC patients.

    Concurrent radiochemotherapy (RCT) is the treatment of choice for patients with locally advanced non-small-cell lung cancer (NSCLC). Two meta-analyses were inconclusive in an attempt to define the optimal concurrent RCT scheme. Besides efficacy, treatment toxicity will influence the appointed treatment of choice. A systematic review of the literature was performed to record the early and late toxicities, as well as overall survival, of concurrent RCT regimens in patients with NSCLC. The databases of PubMed, Ovid, Medline, and the Cochrane Library were searched for articles on concurrent RCT published between January 1992 and December 2009. Publications of phase II and phase III trials with ≥ 50 patients per treatment arm were selected. Patient characteristics, chemotherapy regimen (mono- or polychemotherapy, high or low dose) and radiotherapy scheme, acute and late toxicity, and overall survival data were compared. Seventeen articles were selected: 12 studies with cisplatin-containing regimens and 5 studies using carboplatin. A total of 13 series with mono- or polychemotherapy schedules--as single dose or double or triple high-dose or daily cisplatin-containing (≤ 30 mg/m(2)/wk) chemotherapy were found. Acute esophagitis ≥ grade 3 was observed in up to 18% of the patients. High-dose cisplatin regimens resulted in more frequent and severe hematologic toxicity, nausea, and vomiting than did other schemes. The toxicity profile was more favorable in low-dose chemotherapy schedules. From phase II and III trials published between 1992 and 2010, it can be concluded that concurrent RCT with monochemotherapy consisting of daily cisplatin results in favorable acute and late toxicity compared with concurrent RCT with single high-dose chemotherapy, doublets, or triplets.

    Radiation dose escalation has been shown to improve local control and survival in patients with non-small cell lung cancer in some studies, but randomized data have not supported this premise, possibly owing to adverse effects. Because of the physical characteristics of the Bragg peak, proton therapy (PT) delivers minimal exit dose distal to the target volume, resulting in better sparing of normal tissues in comparison to photon-based radiation therapy. This is particularly important for lung cancer given the proximity of the lung, heart, esophagus, major airways, large blood vessels, and spinal cord. However, PT is associated with more uncertainty because of the finite range of the proton beam and motion for thoracic cancers. PT is more costly than traditional photon therapy but may reduce side effects and toxicity-related hospitalization, which has its own associated cost. The cost of PT is decreasing over time because of reduced prices for the building, machine, maintenance, and overhead, as well as newer, shorter treatment programs. PT is improving rapidly as more research is performed particularly with the implementation of 4-dimensional computed tomography-based motion management and intensity modulated PT. Given these controversies, there is much debate in the oncology community about which patients with lung cancer benefit significantly from PT. The Particle Therapy Co-operative Group (PTCOG) Thoracic Subcommittee task group intends to address the issues of PT indications, advantages and limitations, cost-effectiveness, technology improvement, clinical trials, and future research directions. This consensus report can be used to guide clinical practice and indications for PT, insurance approval, and clinical or translational research directions. PMID:27084663

    Full Text Available Epithelial to mesenchymal transition (EMT has an important role in the development of embryo, as well as that in the metastasis of non-small cell lung cancer (NSCLC. Recent researches have demonstrated that both morphological and phenotypic conversions emerge in cells undergoing EMT. As most of relevant studies were on other cancers, it is essential to uncover whether it is the similar mechanisms accounting for EMT in NSCLC. With the progress of the studies, EMT-related basic researches are gradually applied to predicting the prognosis of NSCLC. The aim of this article was to discuss the mechanisms related to EMT emerging in NSCLC.

    Full Text Available Lung cancer accounts for the majority of cancer-related deaths worldwide of which non-small-cell lung carcinoma alone takes a toll of around 85%. Platinum-based therapy is the stronghold for lung cancer at present. The discovery of various molecular alterations that underlie lung cancer has contributed to the development of specifically targeted therapies employing specific mutation inhibitors. Targeted chemotherapy based on molecular profiling has shown great promise in lung cancer treatment. Various molecular markers with predictive and prognostic significance in lung cancer have evolved as a result of advanced research. Testing of EGFR and Kras mutations is now a common practice among community oncologists, and more recently, ALK rearrangements have been added to this group. This paper discusses various predictive and prognostic markers that are being investigated and have shown significant relevance which can be exploited for targeted treatment in lung cancer.

    Results: A total of 72 patients who had received third-line or higher chemotherapy were included in the analysis. The median age of patients was 49 years (range 41-76, and there were 13 (18.1% women and 59 (81.9% men. Estimated median survival was 26 months. Moreover, overall survival was significantly longer in patients for whom disease control was achieved after second-line chemotherapy compared to those with disease progression (34 vs. 17 months, respectively. Survival after third-line treatment was significantly longer in the group with Eastern Cooperative Oncology Group (ECOG performance status 0-1 at the beginning of third-line therapy compared to patients with a status of 2-3. Conclusions: In patients with advanced stage NSCLC, administration of third-line and higher systemic chemotherapy may be associated with increase in overall survival. Furthermore, greater increases in overall survival were also observed in patients for whom disease control was achieved after second-line therapy and in those with ECOG performance status of 0-1 before third-line treatment.

    Although there have been many advancements in the multidisciplinary management of non-small cell lung cancer (NSCLC), surgery remains the primary modality of choice for resectable lung cancer when the patient is able to tolerate lung resection physiologically. There have been recent advances in surgical diagnosis and treatment of lung cancer. Increasing use of low-dose computed tomography (CT) screening for lung cancer has resulted in increased detection of small peripheral nodules or semi-solid ground glass opacities. Here, we review different modalities of localization techniques that have been used to aid surgical excisional biopsy when needle biopsy has failed to provide tissue diagnosis. We also report on the current debates regarding the use of sublobar resections for Stage I NSCLC as well as the surgical management of locally advanced NSCLC. Finally, we discuss the complex surgical management of T4 NSCLC lung cancers. PMID:26059591

    Breast cancer is the most common cancer in women, and the second most common cause of cancer death after lung cancer. Improvements in the outcome of breast cancer mean that more patients are living longer and are, therefore, at risk of developing a second malignancy. The aim of this review is to present the current understanding of the risk of lung cancer arising in patients previously treated for early stage breast cancer. We review data on the effect of treatment factors (ie, surgery type, radiotherapy technique, and adjuvant chemotherapy) and patient factors (ie, age and smoking) on the risk of developing a subsequent lung cancer. The evidence suggests that older radiotherapy techniques were associated with a substantially increased risk of developing lung cancer in the ipsilateral lung, but there is no clear evidence of an increased risk with modern techniques. Smoking is an important risk factor, and increases the risk of lung cancer in those receiving radiotherapy. Adjuvant chemotherapy is not significantly associated with an increased risk. The risk of developing lung cancer increases with time elapsed since treatment, but any effect of age at treatment is unclear.

    In cases of locally advanced non-small cell lung cancer (NSCLC), concurrent chemoradiotherapy (CCRT) is the leading therapeutic modality. However, much controversy exists about the chemotherapeutic regimens and radiation methods. Materials and Methods: During concurrent chemoradiotherapy, three or four cycles of gemcitabine (500 mg/m2) and cisplatin (30 mg/m2) were administered every two weeks while 50.4 Gy of irradiation was administered in 28 fractions (once/day, 5 treatment days/week) to the tumor site, mediastinum, and the involved lymph node region. In addition, a booster irradiation dose of 18 Gy in 10 fractions was administered to the primary tumor site unless the disease progressed. Two or three cycles of consolidation chemotherapy were performed with gemcitabine (1,200 mg/m2, 1st and 8th day) and cisplatin (60 mg/m2) every three weeks. Results: A total of 29 patients were evaluable for modality response. Response and treatment toxicities were assessed after concurrent chemoradiotherapy and consolidation chemotherapy, respectively. One patient (4%) achieved a complete response; whereas 20 patients (69%) achieved a partial response after concurrent chemoradiotherapy. Following the consolidation chemotherapy, three patients (10.3%) achieved complete responses and 21 patients (72.4%) achieved partial responses. The median follow-up period was 20 months (range 3-39 months) and the median survival time was 16 months (95% CI; 2.4-39.2 months). The survival rates in one, two, and three years after the completion of treatment were 62.7%, 43.9%, and 20%, respectively. Complications associated to this treatment modality included grade 3 or 4 esophagitis, which occurred in 15 patients (51.7%). In addition, an incidence of 24% for grade 3 and 14% for grade 4 neutropenia. Lastly, grade 2 radiation pneumonitis occurred in 6 patients (22%). Conclusion: The response rate and survival time of concurrent chemoradiotherapy with biweekly gemcitabine (500 mg/m2) and cisplatin

    Background A retrospective analysis of clinical data were conducted reviewing patients who were given erlotinib at Peking Union Medical College (PUMC) Hospital from May 2005 to December 2009. Relationships between clinical factors, epidermal growth factor receptor (EGFR) mRNA expression, EGFR gene mutations, KRAS gene mutations and clinical outcomes were investigated in Chinese patients with advanced non-small cell lung cancer (NSCLC). Methods Patients with stage ⅢB/Ⅳ NSCLC who had not previously participated in erlotinib related clinical trials were enrolled into this study. All patients were given oral erlotinib 150 mg per day. Tumor samples of some patients were accessed with mutant-enriched polymerase chain reaction assay (EGFR, KRAS gene mutations) and multiplex branched DNA assay (EGFR mRNA expression).Results Seventy-nine patients were enrolled in this study, 23 patients had a partial response (PR), 36 patients had a stable disease (SD), 20 patients had a PD, with an objective response rate of 29.1%, and a disease control rate of 74.7%.Females (P=0.023), non-smokers (P=0.013), patients with a skin rash (P=0.047), and with highly differentiated tumors (P=0.037) were significantly correlated with the objective response rate. Patients with a lower ECOG PS (P=0.002),highly differentiated tumors (P=0.014), non-smokers (P=0.002), and patients with a skin rash (P <0.001) were significantly correlated with the disease control rate. The median progression-free survival was 35 weeks (95% CI: 13-57 weeks) and 1-year survival was 72.3%. Highly-differentiated tumors (P=0.027) and patients with a skin rash (P <0.001)were significantly correlated with PFS. Seventeen patients were tested for EGFR/KRAS gene mutations and EGFR mRNA expression. Progression-free survival (PFS) of patients with EGFR exon 19/21 mutations was 66 weeks, longer than patients with wild type EGFR exon 19/21 (P=0.018). No significant relationships were found between EGFR mRNA expression, EGFR

    Full Text Available Background and objective Advanced non-small cell lung cancer (NSCLC is characterized by poor treatment efficacy and short survival time. Clinical trials have shown that the combination of chemotherapy with thermotherapy exhibits strong efficacy. We performed this meta-analysis to evaluate the clinical efficacy and safety of gemcitabine plus cisplatin (GP and paclitaxel plus cisplatin (TP combined with thermotherapy in the treatment of NSCLC, as well as to provide reference for clinical practice and future research. Methods We searched international (Cochrane Library, PubMed, and EMBASE and Chinese (CBM, CNKI, VIP and Wanfang databases for relevant articles and imported other retrievable sources, such as tracing-related references. We also corresponded with other authors to obtain certain inaccessible information. Data from all relevant randomized controlled trials (RCT were collected to compare GP or TP thermochemotherapy with GP or TP chemotherapy alone. The quality of the included studies was assessed by adequate outcome-based standards and clinical circumstances. The meta-analysis was conducted using RevMan 5.1. Results Fifteen RCTs involving 952 patients were included in this meta-analysis. The results showed that the thermochemotherapy group had higher rates of improvement in quality of life (OR=3.84, 95%CI: 2.61-5.64, survival at 1 year (HR=1.94, 95%CI: 1.21-3.12, and survival at 2 years (HR=2.05, 95%CI: 1.18-3.58 compared with the chemotherapy group, with the differences between them being significant. However, these groups did not differ in other indicators of treatment effectiveness, such as myelosuppression, alimentary canal reactions, hepatic lesions, and diarrhea. Conclusion Compared with chemotherapy alone, thermochemotherapy can improve survival rates and curative effects, ameliorate symptoms, and enhance the quality of life of patients with advanced NSCLC, and it has an acceptable safety profile. The results of this meta

    Full Text Available An increasing number of patients with advanced non-small cell lung cancer (NSCLC have been treated with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs. However, significant differences in response to EGFR-TKIs have been shown among advanced NSCLC patients. Recently, selection of patients was mainly based on EGFR gene mutation detection. Nevertheless, mutation detection is often limited by tumour tissues derivation, technique complexity, high cost, and so on. It is urgent to seek other biological markers to predict efficacy of EGFR-TKIs. Many studies have founded that the EGFR gene polymorphisms are also associated with clinical outcome and prognosis in treatment of advanced NSCLC with EGFR-TKIs. Here, we presented a review discussing the correlation between EGFR gene polymorphisms and the efficacy of EGFR-TKIs in advanced NSCLC.

    Purpose: To compare helical tomotherapy (HT) and conventional intensity-modulated radiotherapy (IMRT) using a variety of dosimetric and radiobiologic indexes in patients with locally advanced non-small cell lung cancer (LA-NSCLC). Patients and methods: A total of 20 patients with LA-NSCLC were enrolled. IMRT plans with 4-6 coplanar beams and HT plans were generated for each patient. Dose distributions and dosimetric indexes for the tumors and critical structures were computed for both plans and compared. Results: Both modalities created highly conformal plans. They did not differ in the volumes of lung exposed to > 20 Gy of radiation. The average mean lung dose, volume receiving {>=} 30 Gy, and volume receiving {>=} 10 Gy in HT planning were 18.3 Gy, 18.5%, and 57.1%, respectively, compared to 19.4 Gy, 25.4%, and 48.9%, respectively, with IMRT (p = 0.004, p < 0.001, and p < 0.001). The differences between HT and IMRT in lung volume receiving {>=} 10-20 Gy increased significantly as the planning target volume (PTV) increased. For 6 patients who had PTV greater than 700 cm{sup 3}, IMRT was superior to HT for 5 patients in terms of lung volume receiving {>=} 5-20 Gy. The integral dose to the entire thorax in HT plans was significantly higher than in IMRT plans. Conclusion: HT gave significantly better control of mean lung dose and volume receiving {>=} 30-40 Gy, whereas IMRT provided better control of the lung volume receiving {>=} 5-15 Gy and the integral dose to entire thorax. In most patients with PTV greater than 700 cm{sup 3}, IMRT was superior to HT in terms of lung volume receiving {>=} 5-20 Gy. It is therefore advised that caution should be exercised when planning LA-NSCLC using HT. (orig.)

    癌干细胞是目前癌症研究的热点之一。肺癌干细胞与正常肺干细胞有许多共同之处,包括自我更新能力和多分化潜能。许多癌干细胞分子标志为肺癌干细胞所共有,如CD133、CD44、乙醛脱氢酶(aldehyde dehydrogenase, ALDH)以及ATP结合转运蛋白G超家族成员2(ATP-binding cassette sub-family G member 2, ABCG2)。肺癌干细胞的扩增与作用不仅受胚胎干细胞途径如Notch、Hedgehog和Wnt调控,也受肿瘤信号途径如表皮生长因子受体(epidermal growth factor receptor, EGFR)、信号传导转录激活因子3(signal transducer and activator of transcription 3, STAT3)和磷脂酰肌醇3激酶(phosphatidylinositol 3 kinase, PI3K)等的调控。由于癌干细胞在肿瘤复发、转移和耐药性等方面发挥着重要作用,揭示肺癌干细胞与正常干细胞的区别,鉴定并靶向癌干细胞特异性表面标志物及其介导的信号通路,将有望改善肺癌治疗效果和提高患者生存率。%Cancer stem cells (CSCs) are emerging as a hot topic for cancer research. Lung CSCs share many char-acteristics with normal lung stem cells (SCs), including self-renewal and multi-potency for differentiation. Many molecular markers expressed in various types of CSCs were also found in lung CSCs, such as CD133, CD44, aldehyde dehydrogenase (ALDH) and ATP-binding cassette sub-family G member 2 (ABCG2). Similarly, proliferation and expansion of lung CSCs are regulated not only by signal transduction pathways functioning in normal lung SCs, such as Notch, Hedgehog and Wnt path-ways, but also by those acting in tumor cells, such as epidermal growth factor receptor (EGFR), signal transducer and activator of transcription 3 (STAT3) and phosphatidylinositol 3 kinase (PI3K) pathways.

At present, the studies of lung cancer stem cell markers were focused on Side Population cells, CD133, and ALDH,and the signal pathways were focused on the key developmental pathways such as the Wnt, Hedgehog, and Notch.In this paper, we summarized the progress of the lung stem cell and the lung cancer stem cells research briefly.

  20. Radiation and lung cancer

    International Nuclear Information System (INIS)

    The epidemiological data from the atomic bomb survivors and from different groups of Rn-exposed underground miners are so far the main sources of our knowledge on radiation-induced lung cancer. In the first part of this paper the results of these two different data sets are outlined and compared. This comparison concerns the following topics: Primary risk coefficients, the differences between both sexes, the influence of smoking and the variation of the excess relative risk with time since exposure. Of main concern for radiation protection is the possible lung cancer risk of the general population from indoor exposure to radon daughters. In the second part the results of two different types of approaches are discussed: The direct approach from miners data and the so-called dosimetric approach from LSS data. The approach from the atomic bomb survivors' data yields considerably higher risk values for this indoor exposure than the approach from miners. This is particularly valid for females. This difference between both approaches increases if the proposed new dosimetric model for inhaled radon daughters is applied. Possible reasons for this inconsistency and the consequences for radiation protection are outlined. (author)

    Full Text Available The alpha-radioactive polonium 210 (Po-210 is one of the most powerful carcinogenic agents of tobacco smoke and is responsible for the histotype shift of lung cancer from squamous cell type to adenocarcinoma. According to several studies, the principal source of Po-210 is the fertilizers used in tobacco plants, which are rich in polyphosphates containing radio (Ra-226 and its decay products, lead 210 (Pb-210 and Po-210. Tobacco leaves accumulate Pb-210 and Po-210 through their trichomes, and Pb-210 decays into Po-210 over time. With the combustion of the cigarette smoke becomes radioactive and Pb-210 and Po-210 reach the bronchopulmonary apparatus, especially in bifurcations of segmental bronchi. In this place, combined with other agents, it will manifest its carcinogenic activity, especially in patients with compromised mucous-ciliary clearance. Various studies have confirmed that the radiological risk from Po-210 in a smoker of 20 cigarettes per day for a year is equivalent to the one deriving from 300 chest X-rays, with an autonomous oncogenic capability of 4 lung cancers per 10000 smokers. Po-210 can also be found in passive smoke, since part of Po-210 spreads in the surrounding environment during tobacco combustion. Tobacco manufacturers have been aware of the alpha-radioactivity presence in tobacco smoke since the sixties.

    Purpose: We intended to identify risk factors that affect brain metastases (BM) in patients with locally advanced non-small cell lung cancer (LA-NSCLC) receiving definitive radiation therapy, which may guide the choice of selective prevention strategies. Methods and Materials: The characteristics of 346 patients with stage III NSCLC treated with thoracic radiation therapy from January 2008 to December 2010 in our institution were retrospectively reviewed. BM rates were analyzed by the Kaplan-Meier method. Multivariate Cox regression analysis was performed to determine independent risk factors for BM. Results: The median follow-up time was 48.3 months in surviving patients. A total of 74 patients (21.4%) experienced BM at the time of analysis, and for 40 (11.7%) of them, the brain was the first site of failure. The 1-year and 3-year brain metastasis rates were 15% and 28.1%, respectively. In univariate analysis, female sex, age ≤60 years, non-squamous cell carcinoma, T3-4, N3, >3 areas of lymph node metastasis, high lactate dehydrogenase and serum levels of tumor markers (CEA, NSE, CA125) before treatment were significantly associated with BM (P<.05). In multivariate analysis, age ≤60 years (P=.004, hazard ratio [HR] = 0.491), non-squamous cell carcinoma (P=.000, HR=3.726), NSE >18 ng/mL (P=.008, HR=1.968) and CA125 ≥ 35 U/mL (P=.002, HR=2.129) were independent risk factors for BM. For patients with 0, 1, 2, and 3 to 4 risk factors, the 3-year BM rates were 7.3%, 18.9%, 35.8%, and 70.3%, respectively (P<.001). Conclusions: Age ≤60 years, non-squamous cell carcinoma, serum NSE >18 ng/mL, and CA125 ≥ 35 U/mL were independent risk factors for brain metastasis. The possibilities of selectively using prophylactic cranial irradiation in higher-risk patients with LA-NSCLC should be further explored in the future.

    Full Text Available Abstract Background Cancer patients routinely develop symptoms consistent with profound circadian disruption, which causes circadian disruption diminished quality of life. This study was initiated to determine the relationship between the severity of potentially remediable cancer-associated circadian disruption and quality of life among patients with advanced lung cancer. Methods We concurrently investigated the relationship between the circadian rhythms of 84 advanced lung cancer patients and their quality of life outcomes as measured by the EORTC QLQ C30 and Ferrans and Powers QLI. The robustness and stability of activity/sleep circadian daily rhythms were measured by actigraphy. Fifty three of the patients in the study were starting their definitive therapy following diagnosis and thirty one patients were beginning second-line therapy. Among the patients who failed prior therapy, the median time between completing definitive therapy and baseline actigraphy was 4.3 months, (interquartile range 2.1 to 9.8 months. Results We found that circadian disruption is universal and severe among these patients compared to non-cancer-bearing individuals. We found that each of these patient's EORTC QLQ C30 domain scores revealed a compromised capacity to perform the routine activities of daily life. The severity of several, but not all, EORTC QLQ C30 symptom items correlate strongly with the degree of individual circadian disruption. In addition, the scores of all four Ferrans/Powers QLI domains correlate strongly with the degree of circadian disruption. Although Ferrans/Powers QLI domain scores show that cancer and its treatment spared these patients' emotional and psychological health, the QLI Health/Function domain score revealed high levels of patients' dissatisfaction with their health which is much worse when circadian disruption is severe. Circadian disruption selectively affects specific Quality of Life domains, such as the Ferrans/Powers Health

In this review, we summarize the current data from clinical trials with gefitinib and appraise its role in the management of locally advanced or metastatic NSCLC.

    Drugs that specifical y target the tyrosine kinase domain of epidermal growth factor receptor (EGFR), such as erlotinib or gefitinib, have exhibited striking ef icacy in non-smal cel lung cancer (NSCLC) patients har-boring activating EGFR mutations. However, acquired resistance inevitably develops and remains a serious barrier for the successful management of patients with this disease. Multiple mechanisms are reportedly involved in the process of acquired resistance, which provide new insights into the management of EGFR-tyrosine kinase inhibitor (EGFR-TKI) resistance. Here, we provide an overview of the emerging treatment approaches for patients with EGFR-TKI resistance.

    Background BRCA1 is a main component of homologous recombination and induces resistance to platinum in preclinical models. It has been studied as a potential predictive marker in lung cancer. Several proteins modulate the function of BRCA1. The E3 ubiquitin ligase HERC2 facilitates the assembly of the RNF8-UBC13 complex to recruit BRCA1 to DNA damage sites. The combined analysis of multiple components of the pathway leading to the recruitment of BRCA1 at DNA damage sites has the potentiality ...

    Small cell lung cancer (SCLC) is an aggressive cancer of neuroendocrine origin, which is strongly associated with cigarette smoking. Patients typically present with a short duration of symptoms and frequently (60-65 %) with metastatic disease. SCLC is a heterogeneous disease including extremely chemosensitive and chemoresistant clones. For this reason, a high percentage of patients respond to first-line chemotherapy but rapidly succumb to the disease. SCLC is generally divided into two stages, limited and extensive. Standard treatment of limited stage disease includes combination chemotherapy with cisplatin and etoposide for four cycles, thoracic radiation initiated early with the first cycle of chemotherapy, and consideration of prophylactic cranial irradiation (PCI) in the subset of patients with good response. Surgery may play a role in TNM stages I and II. In extensive disease, platinum agents and etoposide, used in combination, are again the first-line standard of care in the USA. However, thoracic radiation therapy is used predominately in patients where local control is important and PCI is of uncertain benefit. Despite these treatments, prognosis remains poor and novel therapies are needed to improve survival in this disease. PMID:27535400

  2. Irradiation lung injury in lung cancer patients

    International Nuclear Information System (INIS)

    The effect of chest irradiation on pulmonary function was studied in 16 patients with lung cancer and one with malignant thymoma. Radiation pneumonitis was detected by chest radiography in 15 cases (88%), 35 days (average) after the completion of radiation therapy. In these cases the radiation field included the lungs, and the hilar and mediastinal regions. No radiation pneumonitis occurred in the other two patients, receiving only lung field irradiation. Various pulmonary functions were measured in all patients following radiation therapy. Inspiratory reserve volume, inspiratory capacity and diffusing capacity were significantly reduced 1 month and 3 months after the completion of radiotherapy. Furthermore, reduction of vital capacity was found 3 months after treatment. It may be concluded that pulmonary function tests are not useful in predicting the onset of radiation pneumonitis, as chest radiography revealed inflammatory changes before the reduction of pulmonary function was detected.

    DNA repair capacity(DRC)is correlated with sensi tivity of cancer cells toward platinum-based chemotherapy.We hypothesize that genetic polymorphisms in DNA repair gene XPA(xeroderma pigmentosum group A)and XPG(xeroderma pigmentosum group G)(ERCC5,excision repair cross-complementation group 5),which result in inter-individual differences in DNA repair efficiency,may predict clinical response to platinum agents in advanced non-small cell lung cancer (NSCLC)patients.In this study,we find that the A→G change of XPA A23G polymorphism significantly increased response to platinum-based chemotherapy.Polymorphism in XPG His46His was associated with a decreased treatment response,but was not statistically significant.

  8. Quality of life assessment in advanced non-small-cell lung cancer patients undergoing an accelerated radiotherapy regimen: report of ECOG study 4593

    International Nuclear Information System (INIS)

    Purpose: To prospectively evaluate the quality of life (QOL) before, at completion, and after therapy for patients receiving an accelerated fractionation schedule of radiotherapy for advanced, unresectable non-small-cell lung cancer in a Phase II multi-institutional trial. Methods and Materials: The Functional Assessment of Cancer Therapy-Lung (FACT-L) patient questionnaire was used to score the QOL in patients enrolled in the Eastern Cooperative Oncology Group Phase II trial (ECOG 4593) of hyperfractionated accelerated radiotherapy in non-small-cell lung cancer. Radiotherapy (total dose 57.6 Gy in 36 fractions) was delivered during 15 days, with three radiation fractions given each treatment day. The protocol was activated in 1993, and 30 patients had accrued by November 1995. The FACT-L questionnaire was administered at study entry (baseline), on the last day of radiotherapy (assessment 2), and 4 weeks after therapy (assessment 3). The FACT-L includes scores for physical, functional, emotional, and social well-being (33 items), and a subscale of lung cancer symptoms (10 additional items). The summation of the physical, functional, and lung cancer symptom subscales (21 items) constitutes the Trial Outcome Index (TOI), considered the most clinically relevant outcome measure in lung cancer treatment trials. Results: The FACT-L completion rates at the designated study time points were as follows: baseline, 30 of 30 (100%); assessment 2, 29 (97%) of 30; and assessment 3, 24 (80%) of 30. At treatment completion, statistically significant declines in QOL scores were noted, compared with baseline for physical and functional well-being. Emotional well-being scores improved at both assessment 2 and assessment 3. The physical and functional scores returned approximately to baseline values at assessment 3. The change in TOI score was evaluated as a function of the clinical response to treatment, toxicity grade, and survival; no clear association was noted. A trend for the

    Squamous cell lung cancer (SQCLC) is one of the most prevalent subtypes of lung cancer worldwide, about 400,000 persons die from squamous-cell lung cancer around the world, and its pathogenesis is closely linked with tobacco exposure. Unfortunately, squamous-cell lung cancer patients do not benefit from major advances in the development of targeted therapeutics such as epidermal growth factor receptor (EGFR) inhibitors or anaplastic lymphoma kinase (ALK) inhibitors that show exquisite activity in lungadenocarcinomas with EGFR mutations or echinoderm microtubule associated protein like-4 (EML4)-ALK fusions, respectively. Major efforts have been launched to characterize the genomes of squamouscell lung cancers. Among the new results emanating from these efforts are amplifications of the fibroblast growth factor receptor 1 (FGFR1) gene, the discoidin domain receptor 2 (DDR2) gene mutation as potential novel targets for the treatment of SQCLCs. Researchers find that there are many specific molecular targeted genes in the genome of squamous-cell lung cancer patients. These changes play a vital role in cell cycle regulation, oxidative stress, cell apoptosis, squamous epithelium differentiation, may be the candidate targeted moleculars in SQCLCs. Here, we provide a review on these discoveries and their implications for clinical trials in squamous-cell lungcancer assessing the value of novel therapeutics addressing these targets.%肺鳞癌(squamous-cell lung cancer, SQCLC)是一种常见的肺癌病理类型,全世界每年约40余万人死于肺鳞癌,发病与吸烟密切相关。然而,研究表明,在肺腺癌中有明显疗效的靶向药物却无法让肺鳞癌患者获益,如人表皮生长因子受体(epidermal growth factor receptor, EGFR)抑制剂、间变性淋巴瘤激酶(anaplastic lymphoma kinase, ALK)抑制剂等。通过大量基因组学研究表明,纤维母细胞生长因子受体1(fibroblast growth factor receptor 1, FGFR1)

    To assess whether tumour heterogeneity, quantified by texture analysis (TA) on contrast-enhanced computed tomography (CECT), can predict response to chemotherapy in advanced non-small cell lung cancer (NSCLC). Fifty-three CECT studies of patients with advanced NSCLC who had undergone first-line chemotherapy were retrospectively reviewed. Response to chemotherapy was evaluated according to RECIST1.1. Tumour uniformity was assessed by a TA method based on Laplacian of Gaussian filtering. The resulting parameters were correlated with treatment response and overall survival by multivariate analysis. Thirty-one out of 53 patients were non-responders and 22 were responders. Average overall survival was 13 months (4-35), minimum follow-up was 12 months. In the adenocarcinoma group (n = 31), the product of tumour uniformity and grey level (GL*U) was the unique independent variable correlating with treatment response. Dividing the GL*U (range 8.5-46.6) into tertiles, lesions belonging to the second and the third tertiles had an 8.3-fold higher probability of treatment response compared with those in the first tertile. No association between texture features and response to treatment was observed in the non-adenocarcinoma group (n = 22). GL*U did not correlate with overall survival. TA on CECT images in advanced lung adenocarcinoma provides an independent predictive indicator of response to first-line chemotherapy. (orig.)

    Lung cancer is one of the most common and deadliest forms of cancer. It accounts for 13% of all new cancer cases and 19% of cancer-related deaths. In India, lung cancer constitutes 6.9% of all new cancer cases and 9.3% of all cancer cases. There has also been a dramatic rise worldwide in both the absolute and relative frequencies of lung cancer occurrence. In 1953 it became the most common cause of cancer mortality in men. By 1985, it became the leading cause of cancer deaths in women, causing almost twice as many deaths as breast cancer. The demographic proifle of lung cancer has changed greatly over the years; however, methods for diagnosing, screening, and managing lung cancer patients have improved. This is due to our growing understanding of the biology of lung cancer. It is now possible to further deifne lung cancer types beyond small cell lung carcinoma and non-small cell lung carcinoma. Moreover, new histology-based therapeutic modalities have been developed, and more new lung cancer biomarkers have been uncovered. Therefore, more detailed histological characterization of lung cancer samples is warranted in order to determine the best course of treatment for speciifc patients. This review article describes how these new molecular technologies are shaping the way lung cancer can be treated in future.

  13. Study of efficacy and toxicity of hypofractionated thoracic radiotherapy 17 gray in 2 fractions for palliation in advanced non-small-cell lung cancer

    International Nuclear Information System (INIS)

    Objective: To determine the efficacy and toxicity of hypofractionated thoracic radiotherapy 17 Gray (Gy) in 2 fractions for palliation in advanced non-small-cell lung carcinoma. Study design: A quasi-experimental study. Place and duration of study: Oncology department, Combined Military Hospital, Rawalpindi, from 4th July 2008 to 4th Nov 2009. Material and Methods: Fifty four patients with histologically and/or cytologically confirmed unresectable stages III and IV non small cell lung cancer, with performance status 2 or 3 and expected survival > 2 months were treated with megavoltage radiation therapy 17 Gy in 2 fractions one week apart, with symptoms due to intrathoracic disease (cough, dyspnea and hemoptysis) and toxicity due to radiation therapy (dysphagia secondary to esophagitis) assessed as per common toxicity criteria adverse event version 3.0 on day 0 before treatment and day 30 after start of treatment. Results: Grades of cough, hemoptysis and dyspnea showed significant improvement after treatment (p<0.001). A total of 42.68% patients showed an improvement in grade of cough (23 out of 54 patients), 85.7% of patients showed improvement in grade of hemoptysis (36 out of 42 patients) and 55.65% patients showed improvement in grade of dyspnea (30 out of 54 patients). Twenty two point two percent patients (12 out of 54) showed increase in grade of dysphagia. Although, there was a statistically significant increase in grade of dysphagia after treatment but it was limited to grade 1 and 2 only. Considering that no patient had grade 3 or 4 dysphagia, this toxicity was acceptable. Conclusion: Based on our results hypofractionated thoracic radiotherapy, 17 Gy in 2 fractions, is effective with acceptable toxicity in palliation in advanced non small cell lung cancer and is recommended as it will result in shorter duration of hospital stay and low hospital stay charges.

    Mutations in the epidermal growth factor receptor (EGFR)gene have been identified as potential targets for the treatment and prognostic factors for non small cell lung cancer (NSCLC). We assessed the correlation between fluorodeoxyglucose (FDG) uptake and EGFR mutations, as well as their prognostic implications. A total of 163 patients with pathologically confirmed NSCLC were enrolled (99 males and 64 females; median age, 60 years). All patients underwent FDG positron emission tomography before treatment, and genetic studies of EGFR mutations were performed. The maximum standardized uptake value (SUVmax)of the primary lung cancer was measured and normalized with regard to liver uptake. The SUVmax between the wild type and EGFR mutant groups was compared. Survival was evaluated according to SUVmax and EGFR mutation status. EGFR mutations were found in 57 patients (60.8%). The SUVmax tended to be higher in wild type than mutant tumors, but was not significantly different (11.1{+-}5.7 vs. 9.8{+-}4.4, P=0.103). The SUVmax was significantly lower in patients with an exon 19 mutation than in those with either an exon 21 mutation or wild type (P=0.003 and 0.009, respectively). The EGFR mutation showed prolonged overall survival (OS) compared to wild type tumors (P=0.004). There was no significant difference in survival according to SUVmax. Both OS and progression free survival of patients with a mutation in exon 19 were significant longer than in patients with wild type tumors. In patients with NSCLC, a mutation in exon 19 was associated with a lower SUVmax and is a reliable predictor for good survival.

    Purpose: We evaluated the effect of a contrast agent (CA) on proton beam range in a treatment planning system (TPS) for patients with locoregionally advanced lung cancer. Methods and Materials: Two sets of computed tomography (CT) images (with and without CA) were obtained from 20 patients with lung cancer. Because the increase in Hounsfield unit ( Increment HU) value of the heart and great vessels due to the effect of CA is most prominent among thoracic structures, to evaluate the effect of CA on proton beam range in the TPS, we compared the calculated distal ranges in the plan with CA-enhanced CT with those with corrected CT, in which the HU values of the heart and great vessels in the CA-enhanced CT were replaced by average HU values obtained from the unenhanced CT. Results: The mean Increment HU value and the longest length of the heart and great vessels within the proton beam path in the field that passed through these structures were 189 {+-} 29 HU (range, 110-250 HU) and 7.1 {+-} 1.1 cm (range, 2.6-11.2 cm), respectively. The mean distal range error in the TPS because of the presence of CA was 1.0 {+-} 0.7 cm (range, 0.2-2.6 cm). Conclusion: If CA-enhanced CT images are used for radiotherapy planning using a proton beam for the treatment of lung cancer, our results suggest that the HU values of the heart and great vessels should be replaced by the average HU values of soft tissue to avoid discrepancies between planned and delivered doses.

    Lung cancer is a leading cause of cancer-related mortality in many countries. Although recent advances in targeted therapy against driver oncogenes have significantly improved patient outcome, cure of this disease is still exceptional. Although tobacco is a known cause of lung cancer, not all smokers develop lung cancer, and conversely many patients, especially Asian female patients with lung cancer, are lifetime never-smokers. Therefore, efforts to understand the basis for different suscepti...

    Purpose: To evaluate localization accuracy resulting from rigid registration of locally-advanced lung cancer targets using fully automatic and semi-automatic protocols for image-guided radiation therapy. Methods: Seventeen lung cancer patients, fourteen also presenting with involved lymph nodes, received computed tomography (CT) scans once per week throughout treatment under active breathing control. A physician contoured both lung and lymph node targets for all weekly scans. Various automatic and semi-automatic rigid registration techniques were then performed for both individual and simultaneous alignments of the primary gross tumor volume (GTVP) and involved lymph nodes (GTVLN) to simulate the localization process in image-guided radiation therapy. Techniques included “standard” (direct registration of weekly images to a planning CT), “seeded” (manual prealignment of targets to guide standard registration), “transitive-based” (alignment of pretreatment and planning CTs through one or more intermediate images), and “rereferenced” (designation of a new reference image for registration). Localization error (LE) was assessed as the residual centroid and border distances between targets from planning and weekly CTs after registration. Results: Initial bony alignment resulted in centroid LE of 7.3 ± 5.4 mm and 5.4 ± 3.4 mm for the GTVP and GTVLN, respectively. Compared to bony alignment, transitive-based and seeded registrations significantly reduced GTVP centroid LE to 4.7 ± 3.7 mm (p = 0.011) and 4.3 ± 2.5 mm (p < 1 × 10−3), respectively, but the smallest GTVP LE of 2.4 ± 2.1 mm was provided by rereferenced registration (p < 1 × 10−6). Standard registration significantly reduced GTVLN centroid LE to 3.2 ± 2.5 mm (p < 1 × 10−3) compared to bony alignment, with little additional gain offered by the other registration techniques. For simultaneous target alignment, centroid LE as low as 3

    Circulating tumor cells (CTCs) have emerged as potential biomarkers in several cancers such as colon, prostate, and breast carcinomas, with a correlation between CTC number and patient prognosis being established by independent research groups. The detection and enumeration of CTCs, however, is still a developing field, with no universal method of detection suitable for all types of cancer. CTC detection in lung cancer in particular has proven difficult to perform, as CTCs in this type of cancer often present with nonepithelial characteristics. Moreover, as many detection methods rely on the use of epithelial markers to identify CTCs, the loss of these markers during epithelial-to-mesenchymal transition in certain metastatic cancers can render these methods ineffective. The development of personalized medicine has led to an increase in the advancement of molecular characterization of CTCs. The application of techniques such as FISH and RT-PCR to detect EGFR, HER2, and KRAS abnormalities in lung, breast, and colon cancer, for example, could be used to characterize CTCs in real time. The use of CTCs as a 'liquid biopsy' is therefore an exciting possibility providing information on patient prognosis and treatment efficacy. This review summarizes the state of CTC detection today, with particular emphasis on lung cancer, and discusses the future applications of CTCs in helping the clinician to develop new strategies in patient treatment.

    Non-small-cell lung cancer (NSCLC) is an increasing global challenge, especially in low-income countries. Most guidelines for the management of advanced-stage NSCLC have limited effect in countries with resource constraints. Following a systematic literature search, we present an overview of the management of advanced-stage NSCLC in the first-line setting, discuss resources required for systemic therapy, and provide treatment recommendations stratified to four resources levels. Treatment guidelines appropriate for different resource levels offer a realistic approach to management of advanced-stage NSCLC, by recognising the limitations of a particular health-care system. Although there are many barriers to cancer control in low-resource countries, these can be overcome by using measures that are culturally appropriate, economically feasible, and evidence-based. Initiatives include strategic planning, tobacco control, training of health-care workers, access to therapeutic agents, acquisition of information, public education, and alliances with established institutions and international organisations.

    Purpose Image-guided radiotherapy for patients with locally advanced lung cancer relies on bony landmarks and carina or - if visible - the primary tumor (PT) for daily patient alignment, neglecting potential variations in the relative position of PT and involved lymph nodes (LN). This study analyzes PT and LN position changes relative to each other and relative to anatomical landmarks during conventionally fractionated radiotherapy. Methods and Materials In 12 patients with locally advanced non-small cell lung cancer PT, LN, carina and one thoracic vertebra were manually contoured on weekly 4D fan beam CTs. Systematic and random interfraction displacements of all contoured structures were identified in the three cardinal directions, resulting setup margins were calculated. Time trends and the effect of volume changes on displacements were analyzed. Results Three-dimensional displacement vectors and systematic/random interfraction displacements were smaller for carina than vertebra both for PT and LN. For PT, mean 3D displacement vectors with carina-based alignment were 7 mm/SD 4 mm versus 9 mm/SD 5 mm with bony anatomy (p0.05). Displacements between PT and bone (p=0.04), and between PT and LN (p=0.01) were significantly correlated with PT volume regression. Displacements between LN and carina were correlated with LN volume change (p=0.03). Conclusions Carina-based setup results in a more reproducible PT and LN alignment than bony anatomy setup. Considering the independence of PT and LN displacement and the impact of volume regression on displacements over time, repeated CT imaging even with primary tumorbased alignment is recommended in locally advanced disease.

    Full Text Available Background and objective Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs has shown a high response rate in the treatment of lung cancer in patients with (EGFR mutation. The aim of this study is to evaluate the relationship between EGFR mutation status in serum and predicting benefit from EGFR-TKIs therapy in patients with advanced non-small cell lung cancer (NSCLC. Methods We examined EGFR mutation status in serum of 80 patients with advanced, EGFR-TKIs given as first-line therapy NSCLC. All patients were received long-term follow-up, and the drug efficacy were observed and evaluated. Results The EGFR mutation in serum was detected in 33.8% (27/80 of NSCLC patients examined, in which exon 19 deletion mutation was present at a frequency of 44.4% (12/27 and exon 21 point mutation was 55.6% (15/27; The response rate to EGFR-TKI in patients with EGFR mutation in serum was (55.6%, 15/27, which was remarkably higher than that in EGFR wild-type patients (17.0%, 9/53, the difference was statistically significant (χ2=0.370, P<0.001; The median progression free survival (PFS of patients with EGFR mutation in serum was remarkably better than that of EGFR wild-type patients (9.8 months vs 5.7 months, P=0.014. Conclusion In patients with advanced, EGFR-positive in serum NSCLC, EGFR-TKIs given as first-line therapy is associated with improved drug efficacy. The results suggest that it is feasible to use serum to detect EGFR mutation, which can predict a benefit from EGFR-TKIs given as first-line therapy.

Systematic and random interfraction displacements of all contoured structures were identified in the 3 cardinal directions, and resulting setup margins were calculated. Time trends and the effect of volume changes on displacements were analyzed. Results: Three-dimensional displacement vectors and systematic/random interfraction displacements were smaller for carina than for vertebra both for PT and LN. For PT, mean (SD) 3-dimensional displacement vectors with carina-based alignment were 7 (4) mm versus 9 (5) mm with bony anatomy (P<.0001). For LN, smaller displacements were found with carina- (5 [3] mm, P<.0001) and vertebra-based (6 [3] mm, P=.002) alignment compared with using PT for setup (8 [5] mm). Primary tumor and LN displacements relative to bone and carina were independent (P>.05). Displacements between PT and bone (P=.04) and between PT and LN (P=.01) were significantly correlated with PT volume regression. Displacements between LN and carina were correlated with LN volume change (P=.03). Conclusions: Carina-based setup results in a more reproducible PT and LN alignment than bony anatomy setup. Considering the independence of PT and LN displacement and the impact of volume regression on displacements over time, repeated CT imaging even with PT-based alignment is recommended in locally advanced disease.

    @@ 1 Introduction Recent progress in molecular biology has enabled us to better understand the molecular mechanism underlying pathogenesis of human malignancy including lung cancer. Sequencing of human genome has identified many oncogenes and tumor suppressor genes,giving us a better understanding of the molecular events leading to the formation, progression, metastasis, and the development of drug resistance in human lung cancer. In addition, many signal transduction pathways have been discovered that play important roles in lung cancer. Novel strategy of anti-cancer drug development now involves the identification and development of targeted therapy that interrupts one or more than one pathways or cross-talk among different signal transduction pathways. In addition, efforts are underway that combine the traditional cytotoxic (non-targeted) agents with the biological (targeted) therapy to increase the response rate and survival in patients with lung cancer, especially advanced non-small cell lung cancer (NSCLC).

    Purpose: To evaluate implanted markers as a surrogate for tumor-based setup during image-guided lung cancer radiotherapy with audiovisual biofeedback. Methods and Materials: Seven patients with locally advanced non-small-cell lung cancer were implanted bronchoscopically with gold coils. Markers, tumor, and a reference bony structure (vertebra) were contoured for all 10 phases of the four-dimensional respiration-correlated fan-beam computed tomography and weekly four-dimensional cone-beam computed tomography. Results: The systematic/random interfractional marker-to-tumor centroid displacements were 2/3, 2/2, and 3/3 mm in the x (lateral), y (anterior-posterior), and z (superior-inferior) directions, respectively. The systematic/random interfractional marker-to-bone displacements were 2/3, 2/3, and 2/3 mm in the x, y, and z directions, respectively. The systematic/random tumor-to-bone displacements were 2/3, 2/4, and 4/4 mm in the x, y, and z directions, respectively. All displacements changed significantly over time (p < 0.0001). Conclusions: Although marker-based image guidance may decrease the risk for geometric miss compared with bony anatomy-based positioning, the observed displacements between markers and tumor centroids indicate the need for repeated soft tissue imaging, particularly in situations with large tumor volume change and large initial marker-to-tumor centroid distance.

    Progress in genetic engineering has made it possible to elucidate the molecular biological abnormalities in lung cancer. Mutations in KRAS and P53 genes, loss of specific alleles, and DNA methylation of the tumor suppressor genes were the major abnormalities investigated between 1980 and the 2000s. In 2004, mutations in the epidermal growth factor receptor (EGFR) gene that cause oncogene addiction were discovered in non-small-cell lung cancers (NSCLCs), especially in adenocarcinomas. Because they are strongly associated with sensitivity to EGFR-tyrosine kinase inhibitors (EGFR-TKIs), a great deal of knowledge has been acquired in regard to both EGFR and other genes in the EGFR family and their downstream genes. Moreover, in 2007 the existence of the echinoderm microtubule-associated protein-like 4 (EML4)-anaplastic lymphoma kinase (ALK) fusion gene was discovered in NSCLC; and the same as EGFR-TKIs, ALK inhibitors are being found to be highly effective in lung cancers that have this translocation. These discoveries graphically illustrate that molecular biological findings are directly linked to the development of clinical oncology and to improving the survival rates of lung cancer patients. Here, we review the remarkable progress in molecular biological knowledge acquired thus far in regard to lung cancer, especially NSCLC, and the future possibilities. PMID:21850578

    Background Platinum-based chemotherapeutics are the most common regimens for advanced non-small-cell lung cancer (NSCLC) patients, and genetic factors are thought to represent important determinants of drug efficacy. We prospectively assessed the status of the XPC Ala499Val and Lys939GIn gene polymorphisms and investigated whether these SNPs can predict the response to cisplatin/carboplatin-based regimens in advanced NSCLC patients in a Chinese population.Methods The treatment outcomes of 96 advanced NSCLC patients who were treated with platinum-based chemotherapy were evaluated. The polymorphic status of xeroderma pigmentosum group C (XPC) gene was genotyped by the 3-D polyacrylamide gel-based DNA microarray method.Results The distributions of XPC Lys939GIn genotypes differed significantly between the response group (complete +partial responses) and the non-response group (stable + progressive disease; P=0.022). The heterozygous A/C genotype carriers had a poorer response rate than the wild A/A genotype carriers in stage Ⅲ (OR, 0.074; 95% CI,0.008-0.704; P=0.023). The XPC Ala499Val polymorphisms were not associated with response to platinum-based chemotherapy.Conclusion Polymorphisms of the XPC gene, Lys939GIn, may be a predictive marker of treatment response for advanced NSCLC patients in stage Ⅲ.

    Full Text Available Background and objective The epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs have been widely used in the treatment of the advanced non-small cell lung cancer (NSCLC, especially in the adenocarcinoma patients with activating EGFR mutations. But there is no published overview of the following treatment. This report through observing the efficacy, toxicity and overall survival of different treatments to the advanced NSCLC patients who had gradual progression after EGFR-TKIs, evaluates the influence of the continued treatment and switching chemotherapy. Methods Retrospective review is conducted on 32 cases of advanced NSCLC patients who experienced treatment failure of EGFR-TKIs. One group accepted the continued treatment and the other group accepted the switching chemotherapy. Results The median overall survival of the continued treatment group is 36.0 months. The respose rate of the switching chemotherapy group is 43.75%, and clinical benefit rate (complete and partial response and stable disease is 87.5%. The median overall survival is 15.5 months. The main toxicities are nausea, vomiting and hematological toxicities. Conclusion For the advanced NSCLC patients who had gradual progression after EGFR-TKIs, the continued treatment is one of the acceptable choices.

    Full Text Available Sarah Baker, Alysa Fairchild Department of Radiation Oncology, Cross Cancer Institute, University of Alberta, Edmonton, AB, Canada Abstract: Radiation-induced esophagitis is the most common local acute toxicity of radiotherapy (RT delivered for the curative or palliative intent treatment of lung cancer. Although concurrent chemotherapy and higher RT dose are associated with increased esophagitis risk, advancements in RT techniques as well as adherence to esophageal dosimetric constraints may reduce the incidence and severity. Mild acute esophagitis symptoms are generally self-limited, and supportive management options include analgesics, acid suppression, diet modification, treatment for candidiasis, and maintenance of adequate nutrition. Esophageal stricture is the most common late sequela from esophageal irradiation and can be addressed with endoscopic dilatation. Approaches to prevent or mitigate these toxicities are also discussed. Keywords: non–small cell lung cancer, acute, late, toxicity, stricture

    Full Text Available Abstract Background Medical oncologists continue to use performance status as a proxy for quality of life (QOL measures, as completion of QOL instruments is perceived as time consuming, may measure aspects of QOL not affected by cancer therapy, and interpretation may be unclear. The pulse oximeter is widely used in clinical practice to predict cardiopulmonary morbidity after lung resection in cancer patients, but little is known on its role outside the surgical setting. We evaluated whether the Lung Cancer Symptom Scale and pulse oximetry may contribute to the evaluation of lung cancer patients who received standard anticancer therapy. Methods We enrolled forty-one consecutive, newly diagnosed, patients with locally advanced or metastatic lung cancer in this study. We developed a survival model with the variables gender, age, histology, clinical stage, Karnofsky performance status, wasting, LCSS symptom scores, average symptom burden index, and pulse oximetry (SpO2. Results Patient and observer-rated scores were correlated, except for the fatigue subscale. The median SpO2 was 95% (range: 86 to 98, was unrelated to symptom scores, and was weakly correlated with observer cough scores. In a multivariate survival model, SpO2 > 90% and patient scores on the LCSS appetite and fatigue subscales were independent predictors of survival. Conclusion LCSS fatigue and appetite rating, and pulse oximetry should be studied further as prognostic factors in lung cancer patients.

This study evaluated the effectiveness and safety of first-line chemotherapy with gemcitabine plus cisplatin (GEM-Cis) 3-week regimen in routine care of Chinese patients with advanced NSCLC.Methods Two hundred and twenty-one patients with NSCLC stage IIIb or IV were enrolled and 209 were eligible foreffectiveness and safety analysis. The median age was 58 (range 29 to 79) years. The percents of cases in stage Ⅳ and stage Ⅲb were 52.2% and 47.8%; of Karnofsky performance score (KPS) less than 80 and 80-100 were 37.3% and 62.7% and of adeno-cancer and non-adeno-cancer were 59.8% and 40.2%. The average number of completed chemotherapy cycles was three. Measures of effectiveness included clinical benefit, significant clinical response (SCR) and adverse effects of GEM-Cis in the treatment of NSCLC at stages Ⅲb/Ⅳ.Results KPS increased from 79±9 at baseline to 86±10 after chemotherapy (P<0.01). Lung cancer symptom scale (LCSS) score of pain, dyspnea and cough increased from 77±24, 74±22 and 63±19 to 92±15, 90±14 and 86±15, respectively (P<0.01). The clinical benefit rate was 85.2% [95% confidence interval (CI) 80.3%-90.0%]. The SCR was 89.5% (95% CI 85.3%-93.7%). Median survival time was 7.8 months (95% CI 7.1 months-9.1 months). Sixty-four patients (30.6%) experienced an adverse effect that was deemed clinically significant. Only one patient (0.5%) was hospitalized due to chemotherapy related adverse effects. Life-threatening toxicity was observed in two patients (1.0%).Conclusion First-line chemotherapy with GEM-Cis in the routine care of Chinese patients with advanced NSCLC is effective and safe.

    Psychological responses to lung cancer have changed over the past 30 years as perceptions of the disease have changed. Previously seen as a fatal diagnosis, it is now regarded as a cancer whose treatment is increasingly effective as the science of the disease advances. The stigma of smoking is diminishing as more is learned about genetic factors and as more nonsmokers are diagnosed. Support groups are now widely available. The increasing social support and greater knowledge of lung cancer provide a more supportive environment in which patients cope with lung cancer today compared with 30 years ago.

    The identification of a subpopulation of tumor cells with stem cell-like characteristics first in hematological malignancies and later in solid tumors has emerged into a novel field of cancer research. It has been proposed that this aberrant population of cells now called "cancer stem cells" (CSCs) drives tumor initiation, progression, metastasis, recurrence, and drug resistance. CSCs have been shown to have the capacity of self-renewal and multipotency. Adopting strategies from the field of stem cell research has aided in identification, localization, and targeting of CSCs in many tumors. Despite the huge progress in other solid tumors such as brain, breast, and colon cancers no substantial advancements have been made in lung cancer. This is most likely due to the current rudimentary understanding of lung stem cell hierarchy and heterogeneous nature of lung disease. In this review, we will discuss the most recent findings related to identification of normal lung stem cells and CSCs, pathways involved in regulating the development of CSCs, and the importance of the stem cell niche in development and maintenance of CSCs. Additionally, we will examine the development and feasibility of novel CSC-targeted therapeutic strategies aimed at eradicating lung CSCs. PMID:27358855

    Full Text Available Xi-Xi Lai, Ren-Ai Xu, Yu-Ping Li, Han Yang Department of Respiratory Medicine, The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, Zhejiang, People’s Republic of China Background: Bevacizumab, a monoclonal antibody against vascular endothelial growth factor ligand, has shown survival benefits in the treatment of many types of malignant tumors, including non-small-cell lung cancer (NSCLC. We conducted this systematic review and meta-analysis to investigate the risk of the most clinically relevant adverse events related to bevacizumab in advanced NSCLC.Methods: Databases from PubMed, Web of Science, and Cochrane Library up to August 2015, were searched to identify relevant studies. We included prospective randomized controlled Phase II/III clinical trials that compared therapy with or without bevacizumab for advanced NSCLC. Summary relative risk (RR and 95% confidence intervals were calculated using random effects or fixed effects according to the heterogeneity among included trials.Results: A total of 3,745 patients from nine clinical trials were included in the meta-analysis. Summary RRs showed a statistically significant bevacizumab-associated increased risk in three of the adverse outcomes studied: proteinuria (RR =7.55, hypertension (RR =5.34, and hemorrhagic events (RR =2.61. No statistically significant differences were found for gastrointestinal perforation (P=0.60, arterial and venous thromboembolic events (P=0.35 and P=0.92, respectively, or fatal events (P=0.29.Conclusion: The addition of bevacizumab to therapy in advanced NSCLC did significantly increase the risk of proteinuria, hypertension, and hemorrhagic events but not arterial/venous thromboembolic events, gastrointestinal perforation, or fatal adverse events.

    We analyzed the association between polymorphisms in three glutathione S-transferase genes (GSTP1, GSTM1, and GSTT1) and the treatment outcome for advanced non-small cell lung cancer (NSCLC). We recruited 284 NSCLC patients at advanced stage from Department of Radiotherapy in Peace Hospital Attached to Changzhi Medical College between May 2009 and May 2011, who had received cisplatin-based chemotherapy. The GSTP1, GSTM1, and GSTT1 genotyping for was determined using DNA pyrosequencing on an ABI Prism 3100 DNA analyzer. In the Cox proportional hazards model, the IIe/Val and Val/Val genotypes of GSTP1 were associated with lower risk of disease progression compared with the IIe/IIe genotype, and the HRs (95%CIs) were 0.37 (0.18-0.74) and 0.15 (0.06-0.35), respectively. The IIe/Val and Val/Val genotypes significantly decreased risk of death from all causes in patients with NSCLC, and the HRs (95%CIs) were 0.52 (0.29-0.92) and 0.37 (0.17- 0.79), respectively No significant association was observed between GSTM1 and GSTT1 polymorphisms and progression-free survival and overall survival in the NSCLC patients. In summary, we suggest that GSTP1 polymorphisms might influence the treatment outcome of advanced NSCLC patients, and our results could help improve individualized therapy. PMID:27525853

      We retrospectively evaluated clinical data before therapy to determine the risk factors for severe neutropenia in advanced non-small-cell lung cancer (NSCLC) patients treated with third-generation agents. We analyzed 100 patients who received such agents (paclitaxel, docetaxel, gemcitabine, irinotecan, or vinorelbine) for advanced NSCLC. The endpoint of the survey was the occurrence of severe neutropenia (grade 4). Risk factors significantly related to severe neutropenia were identified using logistic regression analysis. Of the 100 patients studied, the median age was 62.0 (32-81 years), and 77 (77.0%) were male. CEA 6.6 (0-2220) ng/dL and cytokeratin 19 fragment 21-1 (CYFRA) 4.8 (0.2-173.8) ng/dL before chemotherapy were higher than normal range. Severe neutropenia occurred in 36.0%, the incidence being highest in the first cycle (61.1%). In the univariate analysis, variables associated with severe neutropenia were sex, chest pain, absolute neutrophil count (ANC), Cr, CRP, and CYFRA. In the multivariate analysis, low CYFRA level was identified as a significant risk factor that contributed independently to chemotherapy-induced severe neutropenia (pCYFRA level is the most important risk factor for severe neutropenia in advanced NSCLC patients after the first course of chemotherapy with third-generation agents.

    Full Text Available Background and Objectives: Non-small-cell lung cancer (NSCLC represents approximately 80% of all lung cancers. Unfortunately, at their time of diagnosis, most patients have advanced to unresectable disease with a very poor prognosis. The oriental herbal medicine HangAm-Plus (HAP has been developed for antitumor purposes, and several previous studies have reported its therapeutic effects. In this study, the efficacy of HAP was evaluated as a third-line treatment for advanced-stage IIIb/IV NSCLC. Methods: The study involved six patients treated at the East- West Cancer Center (EWCC from April 2010 to October 2011. Inoperable advanced-stage IIIb/IV NSCLC patients received 3,000 or 6,000 mg of HAP on a daily basis over a 12-week period. Computed tomography (CT scans were obtained from the patients at the time of the initial administration and after 12 weeks of treatment. We observed and analyzed the patients overall survival (OS and progression-free survival (PFS. Results: Of the six patients, three expired during the study, and the three remaining patients were alive as of October 31, 2011. The OS ranged from 234 to 512 days, with a median survival of 397 days and a one-year survival rate of 66.7%. In the 12-week-interval chest CT assessment, three patients showed stable disease (SD, and the other three showed progressive disease (PD. The PFS of patients ranged from 88 to 512 days, the median PFS being 96 days. Longer OS and PFS were correlated with SD. Although not directly comparable, the OS and the PFS of this study were greater than those of the docetaxel or the best supportive care group in other studies. Conclusion: HAP may prolong the OS and the PFS of inoperable stage IIIb/IV NSCLC patients without significant adverse effects. In the future, more controlled clinical trials with larger samples from multi-centers should be conducted to evaluate the efficacy and the safety of HAP.

  17. The cost-effectiveness and cost-utility of high-dose palliative radiotherapy for advanced non-small-cell lung cancer

    International Nuclear Information System (INIS)

    Purpose: To compute cost-effectiveness/cost-utility (CE/CU) ratios, from the treatment clinic and societal perspectives, for high-dose palliative radiotherapy treatment (RT) for advanced non-small-cell lung cancer (NSCLC) against best supportive care (BSC) as comparator, and thereby demonstrate a method for computing CE/CU ratios when randomized clinical trial (RCT) data cannot be generated. Methods and Materials: Unit cost estimates based on an earlier reported 1989-90 analysis of treatment costs at the Vancouver Island Cancer Centre, Victoria, British Columbia, Canada, are updated to 1997-1998 and then used to compute the incremental cost of an average dose of high-dose palliative RT. The incremental number of life days and quality-adjusted life days (QALDs) attributable to treatment are from earlier reported regression analyses of the survival and quality-of-life data from patients who enrolled prospectively in a lung cancer management cost-effectiveness study at the clinic over a 2-year period from 1990 to 1992. Results: The baseline CE and CU ratios are $9245 Cdn per life year (LY) and $12,836 per quality-adjusted life year (QALY), respectively, from the clinic perspective; and $12,253/LY and $17,012/QALY, respectively, from the societal perspective. Multivariate sensitivity analysis for the CE ratio produces a range of $5513-28,270/LY from the clinic perspective, and $7307-37,465/LY from the societal perspective. Similar calculations for the CU ratio produce a range of $7205-37,134/QALY from the clinic perspective, and $9550-49,213/QALY from the societal perspective. Conclusion: The cost effectiveness and cost utility of high-dose palliative RT for advanced NSCLC compares favorably with the cost effectiveness of other forms of treatment for NSCLC, of treatments of other forms of cancer, and of many other commonly used medical interventions; and lies within the US $50,000/QALY benchmark often cited for cost-effective care

  18. Chemotherapy with cisplatin and vinorelbine for elderly patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC)

    International Nuclear Information System (INIS)

    Although modest improvements in the survival of patients with non-small cell lung cancer (NSCLC) can be achieved with cisplatin-based chemotherapy (CT), its value is disputed in the geriatric setting. In this study, we evaluate the feasibility of vinorelbine/cisplatin CT for elderly NSCLC patients. In this pilot phase I/II trial, all patients received CT with vinorelbine 25 mg/m2, on day 1 and 8, and cisplatin on day 1, in 28 days-cycles. After stratification for age (up to 75 years), younger patients were sequentially allocated to moderate cisplatin doses (80 mg/m2 or 90 mg/m2), and older patients were allocated to lower cisplatin doses (60 mg/m2 or 70 mg/m2). We recruited patients aged over 70 years with newly diagnosed NSCLC, clinical stage III or IV, Karnofsky performance status ≥ 70%, normal serum creatinine, peripheral neuropathy ≤ grade 1, and no prior cancer therapy. Analysis was by intention to treat. Main toxicities (grade 3–4) was as follows: neutropenia, 20%; anemia, 11%; and thrombocytopenia, 2%; alopecia, 55%; fatigue, 11%; and peripheral neurotoxicity, 2%. No grade 3–4 emesis or renal toxicity occurred. Global median time to progression (TTP) and overall survival (OS) were 27.0 (95% CI: 10.1 to 43.7) weeks and 30.1 (95% CI: 24.4 to 35.8) weeks; 1- and 2-year survival rates were 36.3% and 13.2%, respectively. Overall response rate was 50.0% (95% CI: 35.4% to 64.5%), with 1 complete response; no difference on response rate was noticed according to cisplatin dose. Median overall survival was 30.1 weeks, with 1- and 2-year survival rates of 36.3% and 13.2%, respectively. Age does not preclude assessment on the role of cisplatin-vinorelbine CT for elderly NSCLC patients with good performance status and adequate bodily functions

    International Nuclear Information System (INIS)

    From August 1978 through December 1979, 51 patients with advanced non-oat cell carcinoma of the lung were enrolled in a Phase I/II trial sponsored by the Radiation Therapy Oncology Group (RTOG) employing misonidazole (a 2-nitroimidazole) as a hypoxic cell sensitizer and radiation. The purpose of this study was to test drug and radiation tolerance and to assess the short term efficacy of this unconventional treatment. Tumor doses of 600 rad were given twice weekly for three weeks for a total of 3600 rad, preceded four to six hours by misonidazole in a dose of 2 gm/m2 or 1.75 gm/m2, administered orally. Forty-nine patients were evaluable. Serious toxicity from this treatment was rare. Grade 2 or 3 peripheral neuro-toxicity occurred in eight of 24 patients (33%) with drug doses of 2 gm/m2 and in four of 26 patients (15%) who received 1.75 gm/m2. Grade 3 or 4 central nervous system toxicity occurred in two patients. Two patients developed serious late radiation complications: one patient had a transverse myelitis that appeared one year following delivery of 3600 rad to the spinal cord; a second patient developed a tracheoesophageal fistula and pericarditis eight months following treatment. Objective responses were reported in 67% of patients (complete in 18%); 70% of the patients died with a median survival time of nine months. Of 32 patients eligible for 12 month follow-up, 34% survived more than one year. Patterns of relapse after initial treatment and comparison with results from other RTOG trials using conventional fractionation are discussed

    Full Text Available Abstract Background Prophylactic cranial irradiation (PCI has been demonstrated to reduce or delay the incidence of brain metastases (BM in locally advanced non-small cell lung carcinoma (LA-NSCLC patients with various prognostic groups. With this current cohort we planned to evaluate the potential usefulness of prophylactic cranial irradiation (PCI specifically in recursive partitioning analysis (RPA Group 1, which is the most favorable group of LA-NSCLC patients. Methods Between March 2007 and February 2008, 62 patients in RPA group 1 were treated with sequential chemoradiotherapy and PCI for stage IIIB NSCLC. The induction chemotherapy consisted of 3 courses of cisplatin (80 mg/m2 and docetaxel (80 mg/m2; each course was given every 21 days. Thoracic radiotherapy (TRT was given at a dose of 60 Gy using 3-D conformal planning. All patients received a total dose of 30 Gy PCI (2 Gy/fr, 5 days a week, beginning on the first day of the TRT. Then, all patients received 3 further courses of the same chemotherapy protocol. Results Six (9.7% patients developed brain metastases during their clinical course. Only one (2% patient developed brain metastasis as the site of first treatment failure. Median brain metastasis-free survival, overall survival, and progression free survival were 16.6, 16.7, and 13.0 months, respectively. By univariate analysis, rates of BM were significantly higher in patients younger than 60 years of age (p = 0.03. Multivariate analysis showed no significant difference in BM-free survival according to gender, age, histology, and initial T- and N-stage. Conclusion The current finding of almost equal bone metastasis free survival and overall survival in patients with LA-NSCLC in RPA group 1 suggests a longer survival for patients who receive PCI, and thereby have a reduced risk of BM.

    Full Text Available To compare the efficacy and toxicities of pemetrexed plus platinum with other platinum regimens in patients with previously untreated advanced non-small cell lung cancer (NSCLC.A meta-analysis was performed using trials identified through PubMed, EMBASE, and Cochrane databases. Two investigators independently assessed the quality of the trials and extracted data. The outcomes included overall survival (OS, progression-free survival (PFS, response rate (RR, and different types of toxicity. Hazard ratios (HRs, odds ratios (ORs and their 95% confidence intervals (CIs were pooled using RevMan software.Four trials involving 2,518 patients with previously untreated advanced NSCLC met the inclusion criteria. Pemetrexed plus platinum chemotherapy (PPC improved survival compared with other platinum-based regimens (PBR in patients with advanced NSCLC (HR = 0.91, 95% CI: 0.83-1.00, p = 0.04, especially in those with non-squamous histology (HR = 0.87, 95% CI: 0.77-0.98, p = 0.02. No statistically significant improvement in either PFS or RR was found in PPC group as compared with PBR group (HR = 1.03, 95% CI: 0.94-1.13, p = 0.57; OR = 1.15, 95% CI: 0.95-1.39, p = 0.15, respectively. Compared with PBR, PPC led to less grade 3-4 neutropenia and leukopenia but more grade 3-4 nausea. However, hematological toxicity analysis revealed significant heterogeneities.Our results suggest that PPC in the first-line setting leads to a significant survival advantage with acceptable toxicities for advanced NSCLC patients, especially those with non-squamous histology, as compared with other PRB. PPC could be considered as the first-line treatment option for advanced NSCLC patients, especially those with non-squamous histology.

  4. SU-E-J-244: Development and Validation of a Knowledge Based Planning Model for External Beam Radiation Therapy of Locally Advanced Non-Small Cell Lung Cancer

    International Nuclear Information System (INIS)

    Purpose: The study aims to develop and validate a knowledge based planning (KBP) model for external beam radiation therapy of locally advanced non-small cell lung cancer (LA-NSCLC). Methods: RapidPlan™ technology was used to develop a lung KBP model. Plans from 65 patients with LA-NSCLC were used to train the model. 25 patients were treated with VMAT, and the other patients were treated with IMRT. Organs-at-risk (OARs) included right lung, left lung, heart, esophagus, and spinal cord. DVH and geometric distribution DVH were extracted from the treated plans. The model was trained using principal component analysis and step-wise multiple regression. Box plot and regression plot tools were used to identify geometric outliers and dosimetry outliers and help fine-tune the model. The validation was performed by (a) comparing predicted DVH boundaries to actual DVHs of 63 patients and (b) using an independent set of treatment planning data. Results: 63 out of 65 plans were included in the final KBP model with PTV volume ranging from 102.5cc to 1450.2cc. Total treatment dose prescription varied from 50Gy to 70Gy based on institutional guidelines. One patient was excluded due to geometric outlier where 2.18cc of spinal cord was included in PTV. The other patient was excluded due to dosimetric outlier where the dose sparing to spinal cord was heavily enforced in the clinical plan. Target volume, OAR volume, OAR overlap volume percentage to target, and OAR out-of-field volume were included in the trained model. Lungs and heart had two principal component scores of GEDVH, whereas spinal cord and esophagus had three in the final model. Predicted DVH band (mean ±1 standard deviation) represented 66.2±3.6% of all DVHs. Conclusion: A KBP model was developed and validated for radiotherapy of LA-NSCLC in a commercial treatment planning system. The clinical implementation may improve the consistency of IMRT/VMAT planning

    Purpose: The study aims to develop and validate a knowledge based planning (KBP) model for external beam radiation therapy of locally advanced non-small cell lung cancer (LA-NSCLC). Methods: RapidPlan™ technology was used to develop a lung KBP model. Plans from 65 patients with LA-NSCLC were used to train the model. 25 patients were treated with VMAT, and the other patients were treated with IMRT. Organs-at-risk (OARs) included right lung, left lung, heart, esophagus, and spinal cord. DVH and geometric distribution DVH were extracted from the treated plans. The model was trained using principal component analysis and step-wise multiple regression. Box plot and regression plot tools were used to identify geometric outliers and dosimetry outliers and help fine-tune the model. The validation was performed by (a) comparing predicted DVH boundaries to actual DVHs of 63 patients and (b) using an independent set of treatment planning data. Results: 63 out of 65 plans were included in the final KBP model with PTV volume ranging from 102.5cc to 1450.2cc. Total treatment dose prescription varied from 50Gy to 70Gy based on institutional guidelines. One patient was excluded due to geometric outlier where 2.18cc of spinal cord was included in PTV. The other patient was excluded due to dosimetric outlier where the dose sparing to spinal cord was heavily enforced in the clinical plan. Target volume, OAR volume, OAR overlap volume percentage to target, and OAR out-of-field volume were included in the trained model. Lungs and heart had two principal component scores of GEDVH, whereas spinal cord and esophagus had three in the final model. Predicted DVH band (mean ±1 standard deviation) represented 66.2±3.6% of all DVHs. Conclusion: A KBP model was developed and validated for radiotherapy of LA-NSCLC in a commercial treatment planning system. The clinical implementation may improve the consistency of IMRT/VMAT planning.

    Purpose: To report the results of a prospective, single-institution study evaluating the feasibility of conventional chemoradiation (CRT) followed by stereotactic body radiation therapy (SBRT) as a means of dose escalation for patients with stage II-III non-small cell lung cancer (NSCLC) with residual disease. Methods and Materials: Patients without metastatic disease and with radiologic evidence of limited residual disease (≤5 cm) within the site of the primary tumor and good or complete nodal responses after standard CRT to a target dose of 60 Gy were considered eligible. The SBRT boost was done to achieve a total combined dose biological equivalent dose >100 Gy to the residual primary tumor, consisting of 10 Gy × 2 fractions (20 Gy total) for peripheral tumors, and 6.5 Gy × 3 fractions (19.5 Gy total) for medial tumors using the Radiation Therapy Oncology Group protocol 0813 definitions. The primary endpoint was the development of grade ≥3 radiation pneumonitis (RP). Results: After a median follow-up of 13 months, 4 patients developed acute grade 3 RP, and 1 (2.9%) developed late and persistent grade 3 RP. No patients developed grade 4 or 5 RP. Mean lung dose, V2.5, V5, V10, and V20 values were calculated for the SBRT boost, and none were found to significantly predict for RP. Only advancing age (P=.0147), previous smoking status (P=.0505), and high CRT mean lung dose (P=.0295) were significantly associated with RP development. At the time of analysis, the actuarial local control rate at the primary tumor site was 82.9%, with only 6 patients demonstrating recurrence. Conclusions: Linear accelerator-based SBRT for dose escalation of limited residual NSCLC after definitive CRT was feasible and did not increase the risk for toxicity above that for standard radiation therapy.

    Objectives: To investigate the relationship between emphysema phenotype, mean lung density (MLD), lung function and lung cancer by using an automated multiple feature analysis tool on thin-section computed tomography (CT) data. Methods: Both emphysema phenotype and MLD evaluated by automated quantitative CT analysis were compared between outpatients and screening participants with lung cancer (n = 119) and controls (n = 989). Emphysema phenotype was defined by assessing features such as extent, distribution on core/peel of the lung and hole size. Adjusted multiple logistic regression models were used to evaluate independent associations of CT densitometric measurements and pulmonary function test (PFT) with lung cancer risk. Results: No emphysema feature was associated with lung cancer. Lung cancer risk increased with decreasing values of forced expiratory volume in 1 s (FEV{sub 1}) independently of MLD (OR 5.37, 95% CI: 2.63–10.97 for FEV{sub 1} < 60% vs. FEV{sub 1} ≥ 90%), and with increasing MLD independently of FEV{sub 1} (OR 3.00, 95% CI: 1.60–5.63 for MLD > −823 vs. MLD < −857 Hounsfield units). Conclusion: Emphysema per se was not associated with lung cancer whereas decreased FEV{sub 1} was confirmed as being a strong and independent risk factor. The cross-sectional association between increased MLD and lung cancer requires future validations.

    Lung cancer is the leading cause of cancer death worldwide. Survival remains poor as approximately 80% of cases present with advanced stage disease. However, new treatments are emerging which offer hope to patients with advanced disease. Insights into cell biology have identified numerous intracellular and extracellular peptides that are pivotal in cancer cell signalling. Disrupting the function of these peptides inhibits intracellular signal transduction and diminishes uncontrolled proliferation, resistance to apoptosis and tumour angiogenesis. The most widely studied signalling pathway is the Epidermal Growth Factor (EGF) pathway. EGF signalling can be disrupted at numerous points. Blockade of the cell surface receptor is achieved by the monoclonal antibody cetuximab; intracellular tyrosine kinase activity is inhibited by erlotinib. Vascular Endothelial Growth Factor (VEGF) regulates another pathway important for tumour growth. Inhibition of VEGF impairs angiogenesis and disrupts metastatic spread. Bevacizumab is a monoclonal antibody that binds to VEGF and blocks interaction with its cell surface receptor. Clinical trials have demonstrated that disruption of these signalling pathways can improve survival in advanced lung cancer. New compounds including folate antimetabolites such as pemetrexed, proteasome inhibitors such as bortezomib, modified glutathione analogues such as TLK286, and other agents such as epothilones and other small molecules are currently being evaluated in patients with lung cancer. As more and more signalling peptides are targeted for manipulation, it is hoped that a new era is dawning in the treatment of advanced stage lung cancer. This review will focus on emerging new therapies in the management of lung cancer.

    Full Text Available Objectives. A phase I pretargeted radioimmunotherapy trial (EudractCT 200800603096 was designed in patients with metastatic lung cancer expressing carcinoembryonic antigen (CEA to optimize bispecific antibody and labelled peptide doses, as well as the delay between their injections.Methods. Three cohorts of 3 patients received the anti-CEA x anti-histamine-succinyl-glycine (HSG humanized trivalent bispecific antibody (TF2 and the IMP288 bivalent HSG-peptide. Patients underwent a pre-therapeutic imaging session S1 (44 or 88 nmol/m2 of TF2 followed by 4.4 nmol/m2, 185 MBq, of 111In-labelled IMP288, and, 1-2 weeks later, a therapy session S2 (240 or 480 nmol/m2 of TF2 followed by 24 nmol/m2, 1.1 GBq/m2, 177Lu-labeled IMP288. The pretargeting delay was 24 or 48 hours. The dose schedule was defined based on pre-clinical TF2 pharmacokinetic studies, on our previous clinical data using the previous anti-CEA pretargeting system and on clinical results observed in the first patients injected using the same system in the Netherlands.Results. TF2 pharmacokinetics (PK was represented by a two-compartment model in which the central compartment volume was linearly dependent on the patient's surface area. PK were remarkably similar, with a clearance of 0.33 +/- 0.03 L/h per m2. 111In- and 177Lu-IMP288 PK were also well represented by a two-compartment model. IMP288 PK were faster (clearance 1.4 to 3.3 l/h. The central compartment volume was proportional to body surface area and IMP288clearance depended on the molar ratio of injected IMP288 to circulating TF2 at the time of IMP288 injection. Modelling of image quantification confirmed the dependence of IMP288 kinetics on circulating TF2, but tumour activity PK were variable. Organ absorbed doses were not significantly different in the 3 cohorts, but the tumour dose was significantly higher with the higher molar doses of TF2 (p < 0.002. S1 imaging predicted absorbed doses calculated in S2. Conclusion. The best

    Full Text Available PURPOSE: This study evaluated occurrence and potential clinical significance of intratumoral EGFR mutational heterogeneity in Chinese patients with non-small cell lung cancer (NSCLC. MATERIALS AND METHODS: Eighty-five stage IIIa-IV NSCLC patients who had undergone palliative surgical resection were included in this study. Of these, 45 patients carried EGFR mutations (group-M and 40 patients were wild-type (group-W. Each tumor sample was microdissected to yield 28-34 tumor foci and Intratumoral EGFR mutation were determined using Denaturing High Performance Liquid Chromatography (DHPLC and Amplification Refractory Mutation System (ARMS. EGFR copy numbers were measured using fluorescence in situ hybridization (FISH. RESULTS: Microdissection yielded 1,431 tumor foci from EGFR mutant patients (group-M and 1,238 foci from wild-type patients (group-W. The EGFR mutant frequencies in group-M were 80.6% (1,154/1,431 and 87.1% (1,247/1,431 using DHPLC and ARMS, respectively. A combination of EGFR-mutated and wild-type cells was detected in 32.9% (28/85 of samples by DHPLC and 28.2% (24/85 by ARMS, supporting the occurrence of intratumoral heterogeneity. Thirty-one patients (36.5% were identified as EGFR FISH-positive. Patients harboring intratumoral mutational heterogeneity possessed lower EGFR copy numbers than those tumors contained mutant cells alone (16.7% vs. 71.0%, P<0.05. Among 26 patients who had received EGFR-TKIs, the mean EGFR mutation content was higher in patients showing partial response (86.1% or stable disease (48.7% compared with patients experiencing progressive disease (6.0% (P = 0.001. There also showed relationship between progression-free survival (PFS and different content of EGFR mutation groups (pure wild type EGFR, EGFR mutation with heterogeneity and pure mutated EGFR (P = 0.001. CONCLUSION: Approximately 30% of patients presented intratumoral EGFR mutational heterogeneity, accompanying with relatively low EGFR copy

    Full Text Available Abstract Background Platinum-based chemotherapy has been a standard therapy for advanced non-small cell lung cancer (NSCLC, but it has high toxicity. In China, Shenqi Fuzheng, a newly developed injection concocted from Chinese medicinal herbs has been reported that may increase efficacy and reduce toxicity when combined with platinum-based chemotherapy, but little is known about it outside of China. The aim of this study was to systematically review the existing clinical evidence on Shenqi Fuzheng Injection(SFI combined with platinum-based chemotherapy for advanced NSCLC. Methods Pubmed, Cochrane Library, EMBASE, CNKI, and CBM search were organized for all documents published, in English and Chinese, until April 2010. The randomized controlled clinical trials were selected based on specific criteria, in which a SFI plus platinum-based chemotherapy treatment group was compared with a platinum-based chemotherapy control group for patients with advanced NSCLC. The quality of studies was assessed by modified Jadad's scale, and Revman 4.2 software was used for data syntheses and analyses. Results Twenty nine studies were included in this review based on our selection criteria. Of them, ten studies were of high quality and the rest were of low quality, according to the modified Jadad scale. The meta-analysis showed there was a statistically significant higher tumor response (RR, 1.19; 95% CI, 1.07 to 1.32; P = 0.001 and performance status ((RR, 1.57; 95% CI, 1.45 to 1.70; P P = 0.016. Conclusions SFI intervention appears to be useful to increase efficacy and reduce toxicity when combined with platinum-based chemotherapy for advanced NSCLC, although this result needs to be further verified by more high-quality trials.

    Background The genotype of epidermal growth factor receptor (EGFR) is associated with tyrosine kinase inhibitor and effectiveness of therapy,but its role in cytotoxic chemotherapy is still unknown.Previous studies indicated that certain EGFR mutations were associated with response and progression free survival following platinum based chemotherapy.Our recent studies have identified that EGFR genotypes in the tumour tissues were not associated with response to the first-line chemotherapy in Chinese patients with advanced non-small cell lung cancer (NSCLC).In this study,we investigated associations of EGFR genotypes from plasma of patients with advanced NSCLC and response to first-line chemotherapy and prognosis.Methods We enrolled 145 advanced NSCLC patients who had received first-line chemotherapy in our department.We examined plasma EGFR genotypes for these patients and associations of EGFR mutations with response to chemotherapy and clinical outcomes.Results There were 54 patients with known EGFR mutations and 91 cases of wild types.No significant difference was detected in the response rate to first-line chemotherapy between mutation carriers and wild-type patients (37.0% vs.31.9%).The median survival time and 1-,2-year survival rates were higher in mutation carriers than wild-types (24months vs.18 months,85.7% vs.65.7% and 43.7% vs.25.9%,P=0.047).Clinical stage (IV vs.Ⅲb),response to the first-line chemotherapy (partial vs.no) and EGFR genotype were independent prognostic factors.Conclusion Plasma EGFR mutations in the Chinese patients with advanced NSCLC is not a predictor for the response to first-line chemotherapy,but an independent prognostic factor indicating longer survival.

  17. Association between TYMS expression and efficacy of pemetrexed-based chemotherapy in advanced non-small cell lung cancer: a meta-analysis.

    Full Text Available BACKGROUND: The predictive value of thymidylate synthase (TYMS to sensitivity to pemetrexed-based chemotherapy in advanced non-small cell lung cancer (NSCLC patients is controversial. We conducted a meta-analysis of all relevant published data to assess the association of TYMS expression with the clinical outcomes of pemetrexed-based regimen in advanced NSCLC. PATIENTS AND METHODS: We conducted an electronic search using using PubMed, Embase, OVID and Cochrane Library databases and manual search. Pooled odds ratio (OR for the response rate and hazard ratio (HR for the overall survival and progression free survival were calculated using the software Revman 5.0. RESULTS: There were 11 studies (n=798 met our criteria for evaluation. Response rate to pemetrexed-based regimen was significantly higher in patients with low/negative TYMS (OR=2.96, 95%CI [1.81, 4.86] P<0.0001. Patients with low/negative TYMS who were treated with pemetrexed-based regimen had longer progression free survival (HR 0.50, 95%CI [0.41, 0.61] P <0.00001 and overall survival (HR 0.41, 95%CI [0.22, 0.78] P=0.007 than those with high/positive TYMS. CONCLUSIONS: Low/negative TYMS expression was significantly associated with higher response rate, longer median survival and longer progression free survival for advanced NSCLC patients receiving pemtrexed-based chemotherapy. Hence, TYMS may be a potential predictor of sensitivity to pemtrexed-based chemotherapy in advanced NSCLC. Large scale prospective clinical trials are still warranted.

    Directory of Open Access Journals (Sweden)

    Graham W Warren

    2013-01-01

    Full Text Available Tobacco use in cancer patients is associated with increased cancer treatment failure and decreased survival. Nicotine is one of over 7,000 compounds in tobacco smoke and nicotine is the principal chemical associated with addiction. The purpose of this article is to review the tumor promoting activities of nicotine. Nicotine and its metabolites can promote tumor growth through increased proliferation, angiogenesis, migration, invasion, epithelial to mesenchymal transition, and stimulation of autocrine loops associated with tumor growth. Furthermore, nicotine can decrease the biologic effectiveness of conventional cancer treatments such as chemotherapy and radiotherapy. Common mechanisms appear to involve activation of nicotinic acetylcholine receptors and beta-adrenergic receptors leading to downstream activation of parallel signal transduction pathways that facilitate tumor progression and resistance to treatment. Data suggest that nicotine may be an important mechanism by which tobacco promotes tumor development, progression, and resistance to cancer treatment.

    Full Text Available Background and objective Currently available studies on the polymorphisms of drug-metabolizing enzymes and their chemotherapeutic effects in non-small cell lung cancer are not consistent. In the present study, the relationship of the gene polymorphisms of cytochrome P450 1A1 (CYP1A1, cytochrome P450 2E1 (CYP2E1, cytochrome P450 2D6 (CYP2D6, and glutathione S-transferase M1 (GSTM1 enzymes with chemotherapeutic effects were investigated. The effects of these relationships on the survival of advanced non-small cell lung cancer patients were also examined. Methods Four drug metabolism enzymes were genotyped in lung cancer patients by polymerase chain reaction (PCR and PCR-restriction fragment length polymorphism. These patients were followed for five years. Results The chemotherapeutic effect on patients carrying B-type CYP1A1 and null-type GSTM1 was better than on those carrying other types (P<0.001. The chemotherapeutic effect on patients carrying A-type CYP1A1 was better than on those carrying the B and C types when non-platinum drugs were administered (P=0.041. The chemotherapeutic effect on patients carrying null-type GSTM1 was better than on those carrying the functional type when platinum drugs were administered (P=0.011. The four enzymes did not affect the overall survival (OS of advanced non-small cell lung cancer patients (P>0.05. Conclusion The chemotherapeutic effect on patients carrying A-type CYP1A1 was better than on those carrying the B and C types when non-platinum drugs were administered. The chemotherapeutic effect on patients carrying null-type GSTM1 was better than on those carrying the functional type when platinum drugs were administered. The four enzymes did not affect the OS of advanced non-small cell lung cancer patients.

  3. Phosphoproteomics and Lung Cancer Research

    William C. S. Cho

    2012-09-01

    Full Text Available Massive evidence suggests that genetic abnormalities contribute to the development of lung cancer. These molecular abnormalities may serve as diagnostic, prognostic and predictive biomarkers for this deadly disease. It is imperative to search these biomarkers in different tumorigenesis pathways so as to provide the most appropriate therapy for each individual patient with lung malignancy. Phosphoproteomics is a promising technology for the identification of biomarkers and novel therapeutic targets for cancer. Thousands of proteins interact via physical and chemical association. Moreover, some proteins can covalently modify other proteins post-translationally. These post-translational modifications ultimately give rise to the emergent functions of cells in sequence, space and time. Phosphoproteomics clinical researches imply the comprehensive analysis of the proteins that are expressed in cells or tissues and can be employed at different stages. In addition, understanding the functions of phosphorylated proteins requires the study of proteomes as linked systems rather than collections of individual protein molecules. In fact, proteomics approaches coupled with affinity chromatography strategies followed by mass spectrometry have been used to elucidate relevant biological questions. This article will discuss the relevant clues of post-translational modifications, phosphorylated proteins, and useful proteomics approaches to identify molecular cancer signatures. The recent progress in phosphoproteomics research in lung cancer will be also discussed.

    In a prospective randomized study, 287 patients with advanced non-small cell lung cancer (NSCLC) stage IIIb or IV with ECOG performance status (PS) 0-1 or 2 were randomly assigned to receive either best supportive care (BSC) or supportive care plus combination chemotherapy (IEP regimen: ifosfamide 3 gm/m2 IV with mesna uroprotection, epirubicin 60 mg/m2 IV on day 1 and cisplatin 60 mg/m2 IV on day 2; or MVP regimen: mitomycin-C 8 mg/m2, cisplatin 100 mg/m2 IV on day 1, vinblastine 4 mg/m2 IV on days 1 and 15). Serial assessment of Karnofsky performance status (KPS), modified Functional Living Index-Cancer (T-FLIC) and modified Quality of Life-Index (T-QLI) were used to estimate the quality of life. Interviews were done at entry, at the third month and at 2 months post complete treatment. At least two courses of chemotherapy were considered to be adequate for response evaluation. Patients were treated for a total of four to six courses or until progression of disease. Partial response rates were 40 and 41.7% in IEP and MVP arms. Median survival durations were 5.9 and 8.1 months for the IEP and MVP chemotherapy arms, and 4.1 months for BSC (log-rank test: P = 0.0003). One year survival was 13, 29.8 and 39.3% for the BSC, IEP and MVP regimens, respectively. Two years survival was 7.8, 6.4 and 13.1% for the BSC, IEP and MVP regimens, respectively. Improvement in quality of life (QOL) scores at the first, second and third interview were seen in chemotherapy arms only, not in the BSC arm. We conclude that combination chemotherapy improves the quality of life as well as prolonging the survival of patients with advanced NSCLC.

While the regimen is associated with several grade ≥3 toxicities, hyponatremia is not a commonly reported adverse effect. Here we report an unusually high incidence of grade ≥3 hyponatremia in Indian patients receiving pemetrexed-platinum doublet, and the pharmacological basis for this phenomenon. Methods: Forty-six patients with advanced NSCLC were enrolled for a bioequivalence study of two pemetrexed formulations. All patients received the pemetrexed-platinum doublet for six cycles followed by single-agent pemetrexed maintenance until progression. Pharmacokinetic blood samples were collected at predefined time points during the first cycle and the concentration-time profile of pemetrexed was investigated by noncompartmental analysis. Hyponatremic episodes were investigated with serum electrolytes, serum osmolality, urinary sodium, and urine osmolality. Results: Sixteen of 46 patients (35% had at least one episode of grade ≥3 hyponatremia. Twenty-four episodes of grade ≥3 hyponatremia were observed in 200 cycles of doublet chemotherapy. Plasma exposure to pemetrexed was significantly higher in patients with high-grade hyponatremia than in those with low-grade or no hyponatremia (P=0.063 and P=0.001, respectively. Pemetrexed clearance in high-grade hyponatremia was quite low compared with normal and low-grade hyponatremia (P=0.001 and P=0.055, respectively. Median pemetrexed exposure in this cohort was much higher than that reported in the literature from Western studies. Conclusion: Higher exposure to

    Full Text Available Background and objective Patients suffering from lung cancer often have poor quality of life after pneumonectomy. It has clinical significances to preserve maximum lobes of the “healthy” lung. The aim of this study is to report the applications of lung replantation in treatment of superior lobe central lung cancer. Methods Three lung cancer cases were included and analysed. The bronchus and margin of lower lung lobe were encroached by cancer. Pulmonary artery was invaded and surrounded by metastatic lymph node. Complete pneumonectomy, antegrade perfusion and retroperfusion with low-potassium dextran (LPD solution in vitro were performed. The retainable lower pulmonary lobe was selected from the isolated lung and superior pulmonary vein was replaced with inferior pulmonary veins. The bronchus and pulmonary artery were inosculated by turns. Results The operative cumulative time ranged from 220 min to 250 min. The isolated time of lobus inferior pulmonary ranged from 120 min to 150 min. The chest tube was pulled out after chest X-ray confirmed the reimplant lung full re-expansion. The patients were followed up for 4 months to 8 months and accomplished adjuvant chemotherapy for 3 or 4 periodicities. The patients had a sound quality of life. Conclusion Lung replantation removing the extensive tumor tissue and retaining the maximum pulmonary normal tissue is an useful method for treatment of lung cancer.

    Lung cancer is one of the most commonly diagnosed cancers in both men and women worldwide. It is also one of the most common forms of cancer in Ireland, accounting for about 20% of all deaths from cancer each year. Early detection of lung cancer is infrequent, and most cases are not diagnosed and treated until they are at an advanced stage. Distant metastases in lung cancer commonly involve the adrenal glands, liver, bones, and central nervous system; they are only rarely seen in the skeletal system. We report a rare case of metastasis to the gluteal muscle as the initial presentation of lung cancer.

    Lung cancer is the leading cause of cancer related death throughout the world. Lung cancer is an example of a disease for which a large percentage of the high-risk population can be easily identified via a smoking history. This has led to the investigation of lung cancer screening with low-dose helical/multi-detector CT. Evidences suggest that early detection of lung cancer allow more timely therapeutic intervention and thus a more favorable prognosis for the patient. The positive relationshi...

    Development of the target therapies of lung cancer was a rapid process which fundamentally changed the pathological diagnosis as well. Furthermore, molecular pathology became essential part of the routine diagnostics of lung cancer. These changes generated several practical problems and in underdeveloped countries or in those with reimbursement problems have been combined with further challenges. The central and eastern region of Europe are characterized by similar problems in this respect which promoted the foundation of NSCLC Working Group to provide up to date protocols or guidelines. This present paper is a summary of the molecular pathology and target therapy guidelines written with the notion that it has to be upgraded continuously according to the development of the field.

    Objective:To explore the significance of epidermal growth factor receptor (EGFR) gene mutations in targeted therapy for patients with advanced non-small cell lung cancer (NSCLC). Methods:One hundred and seventeen patients with advanced NSCLC admitted in Maternal and Child Health Care Center of Zibo City from Jan., 2011 to Jan., 2014 were performed with EGFR gene detection and then divided into 3 groups according to the detecting results. Patients in group A and group B were given oral geiftinib, 250 mg/d while patients in Group C with docetaxel, 75 mg/m2. Chemotherapy for 3 groups was discontinued until severe adverse reactions or disease progression occurred, or continuous treatment was considered to be unfavorable by the doctors, or patients asked for withdrawal from the study. The relationship between clinicopathological features and EGFR mutations were analyzed. The short-term and long-term efifcacy and adverse reactions of 3 groups were observed. Results:Of the 31 cases with EGFR mutations, there were 16 cases (51.6%) of mutations in exon 19, 14 (45.2%) in exon 21 and 2 (6.45%) in exon 18. No EGFR mutation was found in exon 20. EGFR mutations were associated with histological types of tumors and whether patients were smoking. The median follow-up time was 26 months and 62 patients were dead. None of CR was in 3 groups. The disease control rate (DCR) in group A was obviously higher than that in group B (χ2=9.382,P=0.002), which was also higher in group C than that in group B (χ2=4.674,P=0.031). The 1-year survival rate in group A was obviously higher than that in group B and group C (P Conclusion:EGFR mutations are the main indicators for guiding the targeted therapy for patients with advanced NSCLC.

  12. Gene-guided Gefitinib switch maintenance therapy for patients with advanced EGFR mutation-positive Non-small cell lung cancer: an economic analysis

    International Nuclear Information System (INIS)

    Maintenance therapy with gefitinib notably improves survival in patients with advanced non-small cell lung cancer (NSCLC) and EGFR mutation-positive tumors, but the economic impact of this practice is unclear. A decision-analytic model was developed to simulate 21-day patient transitions in a 10-year time horizon. The clinical data were primarily obtained from the results of a pivotal phase III trial that assessed gefitinib maintenance treatment in patients with advanced NSCLC. The cost data were derived from the perspective of the Chinese health care system. The primary outcome was the incremental cost-effectiveness ratio (ICER) at a willingness-to-pay (WTP) threshold of 3 times the per capita GDP of China. Sensitivity analyses were used to explore the impact of uncertainty regarding the results. The impact of the gefitinib patient assistance program (GPAP) was evaluated. After EGFR genotyping, gefitinib maintenance treatment for advanced NSCLC with EGFR mutations increased the life expectancy by 0.74 years and 0.46 QALYs compared with routine follow-up at an additional cost of $26,149.90 USD ($7,178.20 with the GPAP). The ICER for gefitinib maintenance was $57,066.40 and $15,664.80 per QALY gained (at a 3% discount rate) without and with the GPAP, respectively. The utility of progression free survival, the hazard ratio of progression-free survival for gefitinib treatment and the cost of gefitinib per dose were the three factors that had the greatest influence on the results. These results indicate that gene-guided maintenance therapy with gefitinib with the GPAP might be a cost-effective treatment option

    Full Text Available Abstract Background Basic research of gefitinib (Iressa, ZD1839 has demonstrated the combination effects of gefitinib and chemotherapy were sequence-dependent. To evaluate the efficacy of sequential administration of gefitinib following a minor response or partial response to two to three cycles of chemotherapy, a phase II clinical trial was done in Chinese patients with advanced non-small-cell lung cancer (NSCLC. Methods Thirty-three consecutive patients with advanced NSCLC that had been pretreated with at least one chemotherapeutic regimen and were responding to chemotherapy following 2 to 3 cycles of treatment, entered the trial from May 2004 to February 2006. Patients received gefitinib at an oral dose of 250 mg once daily for 4 weeks. Results Thirty-three patients were evaluable for response and toxicity. The objective response rate was 24.2% (8 of 33(95% CI, 11% to 42%. The symptom improvement rate was 54.5% (18 of 33 (95% CI, 41% to 69%. The median duration of response was 7 months (95%CI, 4.0 to 13.2 months. The median time to disease progression (TTP was 6.5 months (95%CI, 0.7 to 16.6 months. The median overall survival time (OS was 9.8 months (range, 2.1 to 18.0 months, and the actuarial 1-year survival was 36.4%. Toxicity was relatively mild and included only one patient (3.0% with grade 4 diarrhea, 1 (3.0% with grade 3 rash, 1 (3.0% with grade 3 nausea, and 1 with grade 3 vomiting (3.0%. Conclusion Preliminary results suggest that sequential administration of gefitinib following a response to chemotherapy may be beneficial for Chinese patients with advanced NSCLC. Further randomized clinical trials are needed.

    Full Text Available BACKGROUND: Combining targeted therapy has been extensively investigated in previously treated advanced non-small-cell lung cancer (NSCLC, but it is still unclear whether combining targeted therapy might offer any benefits against standard monotherapy with erlotinib. We thus performed a meta-analysis of randomized controlled trials to compare the efficacy and safety of combining targeted therapy versus erlotinib alone as second-line treatment for advanced NSCLC. METHODS: Several databases were searched, including Pubmed, Embase and Cochrane databases. The endpoints were overall survival (OS, progression-free survival (PFS, overall response rate (ORR and grade 3 or 4 adverse event (AEs. The pooled hazard ratio (HR or odds ratio (OR, and 95% confidence intervals (CI were calculated employing fixed- or random-effects models depending on the heterogeneity of the included trials. RESULTS: Eight eligible trials involved 2417 patients were ultimately identified. The intention to treatment (ITT analysis demonstrated that combining targeted therapy significantly improved OS (HR 0.90, 95% CI: 0.82-0.99, p = 0.024, PFS (HR 0.83, 95% CI: 0.72-0.97, p = 0.018, and ORR (OR 1.35, 95% CI 1.01-1.80, P = 0.04. Sub-group analysis based on phases of trials, EGFR-status and KRAS status also showed that there was a tendency to improve PFS and OS in combining targeted therapy, except that PFS for patients with EGFR-mutation or wild type KRAS favored erlotinib monotherapy. Additionally, more incidence of grade 3 or 4 rash, fatigue and hypertension were observed in combining targeted therapy. CONCLUSIONS: With the available evidence, combining targeted therapy seems superior over erlotinib monotherapy as second-line treatment for advanced NSCLC. More studies are still needed to identify patients who will most likely benefit from the appropriate combining targeted therapy.

    Full Text Available Background and objective All the advanced NSCLC patients that received EGFR-TKI therapy will eventually relapse after a period of efficacy. The aim of this study is to investigate the serum biomarkers as potential predictive factors for the efficacy of epidermal growth factor receptor (EGFR tyrosine kinase inhibitor (TKI targeted therapy in advanced non-small cell lung cancer. Methods Twenty self-paired serum samples were collected from 9 advanced NSCLC patients that evaluated as disease control (SD or PR after gefinitib therapy, at the time points of before and after gefinitib treatment but 2 weeks before being evaluated as disease progress. All samples were pre-separated by WCX microbeads, and then detected on the MALDI-TOF-MS platform of Bruker AutoflexTM. ClinProTools (Version: 2.1 was used to analyze the differentially expressed proteins. Results There were 7 protein peaks (m/z, 3242.09, 8 690.36, 2 952.64, 3 224.04, 1 450.51, 1 887.8 and 3 935.73 found statistically differentially expressed between the self-paired samples. Three proteins (3 242.09, 2 952.64 and 3 224.04 were down-regulated and four proteins (8 690.36, 1 450.51, 1 887.8 and 3 935.73 up-regulated in gefinitib treated sera. Conclusion The data here suggest that several specific protein peaks might indicate gefinitib resistance, yet the identities of these proteins and the mechanisms underlying the responsiveness to gefinitib treatment need further investigation.

    Background Insufficient data exist on the results of minimally invasive surgery (MIS) for locally advanced non-small cell lung cancer (NSCLC) traditionally approached by thoracotomy. The use of telerobotic surgical systems may allow for greater utilization of MIS approaches to locally advanced disease. We will review the existing literature on MIS for locally advanced disease and briefly report on the results of a recent study conducted at our institution. Methods We performed a retrospective review of a prospective single institution database to identify patients with clinical stage II and IIIA NSCLC who underwent lobectomy following induction chemotherapy. The patients were classified into two groups (MIS and thoracotomy) and were compared for differences in outcomes and survival. Results From January 2002 to December 2013, 428 patients {397 thoracotomy, 31 MIS [17 robotic and 14 video-assisted thoracic surgery (VATS)]} underwent induction chemotherapy followed by lobectomy. The conversion rate in the MIS group was 26% (8/31) The R0 resection rate was similar between the groups (97% for MIS vs. 94% for thoracotomy; P=0.71), as was postoperative morbidity (32% for MIS vs. 33% for thoracotomy; P=0.99). The median length of hospital stay was shorter in the MIS group (4 vs. 5 days; P<0.001). The 3-year overall survival (OS) was 48.3% in the MIS group and 56.6% in the thoracotomy group (P=0.84); the corresponding 3-year DFS were 49.0% and 42.1% (P=0.19). Conclusions In appropriately selected patients with NSCLC, MIS approaches to lobectomy following induction therapy are feasible and associated with similar disease-free and OS to those following thoracotomy.

    Objective: This is a retrospective study to assess the effectiveness of consolidation radiotherapy (CRT) following palliative chemotherapy in patients with metastatic or locally advanced non-small cell lung cancer (NSCLC) who are not suitable for radical treatment. Methods: This study involved retrospective analysis of a prospective database of Northampton Oncology Centre from January 2005 to December 2010,63 patients with advanced/metastatic NSCLC treated at the oncology centre were enrolled. Patients were either treated with high dose (39/36 Gy /13-12 fractions, group 1) or low dose (20 Gy / 5 fractions, group 2) CRT or those were not offered any CRT (group 3). Results: There was no significant difference between the three groups as regard age, sex, performance status, comorbidities or chemotherapy given. However there was a statistically significant difference as regard the stage P = 0.009 with more stage IV patients at group Ⅱ and Ⅲ compared to group l. The mean survival for the three groups was 27 months, 14 months &15 months, respectively. There was a statistically significant improvement of survival in patients treated with high dose palliative CRT compared to the other two groups (P = 0.006). In multivariate analysis only the radiotherapy dose remains as the only statistical significant factor affecting the survival with hazard ratio 0.372 and confidence interval (0.147-0.726). Conclusion: Despite the limitation of our retrospective study, it is worth considering CRT approach for patients with advanced and metastatic NSCLC - not suitable for radical treatment - who have not progressed on chemotherapy.

    Many centres continue to decline percutaneous lung biopsy (PLB) in patients with poor lung function (particularly FEV1 pneumothorax. This practice limits access to novel lung cancer therapies and minimally invasive surgical techniques. Our retrospective single-centre analysis of 212 patients undergoing PLB, all performed prospectively and blinded to lung function, demonstrates that using ambulatory Heimlich valve chest drain (HVCD) to treat significant postbiopsy pneumothorax facilitates safe, diagnostic, early discharge lung biopsy irrespective of lung function with neither FEV1 pneumothorax outcomes. Incorporating ambulatory HVCD into standard PLB practice thereby elegantly bridges the gap that currently exists between tissue diagnosis in patients with poor lung function and the advanced therapeutic options available for this cohort.

    Full Text Available Abstract Background Erlotinib and pemetrexed have been approved for the second-line treatment of non-small cell lung cancer (NSCLC. These two agents have different mechanisms of action. Combined treatment with erlotinib and pemetrexed could potentially augment the antitumor activity of either agent alone. In the present study, we investigated the safety profile of combined administration of the two agents in pretreated NSCLC patients. Methods A phase I dose-finding study (Trial registration: UMIN000002900 was performed in patients with stage III/IV nonsquamous NSCLC whose disease had progressed on or after receiving first-line chemotherapy. Patients received 500 mg/m2 of pemetrexed intravenously every 21 days and erlotinib (100 mg at Level 1 and 150 mg at Level 2 orally on days 2–16. Results Twelve patients, nine males and three females, were recruited. Patient characteristics included a median age of 66 years (range, 48–78 years, stage IV disease (nine cases, adenocarcinoma (seven cases and activating mutation-positives in the epidermal growth factor receptor gene (two cases. Treatment was well-tolerated, and the recommended dose of erlotinib was fixed at 150 mg. Dose-limiting toxicities were experienced in three patients and included: grade 3 elevation of serum alanine aminotransferase, repetitive grade 4 neutropenia that required reduction of the second dose of pemetrexed and grade 3 diarrhea. No patient experienced drug-induced interstitial lung disease. Three patients achieved a partial response and stable disease was maintained in five patients. Conclusions Combination chemotherapy of intermittent erlotinib with pemetrexed was well-tolerated, with promising efficacy against pretreated advanced nonsquamous NSCLC.

    2012-01-01

    Full Text Available Interstitial lung diseases (ILDs represent a heterogeneous group of more than two hundred diseases of either known or unknown etiology with different pathogenesis and prognosis. Lung cancer, which is the major cause of cancer death in the developed countries, is mainly attributed to cigarette smoking and exposure to inhaled carcinogens. Different studies suggest a link between ILDs and lung cancer, through different pathogenetic mechanisms, such as inflammation, coagulation, dysregulated apoptosis, focal hypoxia, activation, and accumulation of myofibroblasts as well as extracellular matrix accumulation. This paper reviews current evidence on the association between lung cancer and interstitial lung diseases such as idiopathic pulmonary fibrosis, sarcoidosis, systemic sclerosis, dermatomyositis/polymyositis, rheumatoid arthritis, systemic lupus erythematosus, and pneumoconiosis.

    Full Text Available In recent years, the five-year survival rate of patients with advanced stage non-small cell lung cancer (NSCLC remains low despite recent advances in surgery, irradiation, chemotherapy, and targeted therapy. Immunotherapy which utilizes the immune system to control and eradicate cancer is a viable treatment approach for malignancy. Immunotherapy in patients with lung cancer has made breakthrough progress recently. Novel immunotherapeutic agents, such as antigen-specific tumour vaccines, checkpoint inhibitors, etc, have all been evaluated in lung cancer, and some have shown prolonged survival time in phase II trials and III trails. The immune-related response criteria for the evaluation of antitumor responses with immunotherapeutic agents have been made. Now, immunotherapy will likely be a fundamentally new concept for the treatment of NSCLC.

    Full Text Available Motivation Until recently it was considered that 65 years is cutoff for defining patients as elderly, but newer reports indicate that this age limit shift to 70 years of age. Elderly patients with advanced non small cell lung cancer, associated comorbidities and poor performance status represent a specific population and a challenge for use of chemotherapy. Primary aim was to evaluate the impact of mono therapy with oral etoposide on overall survival in elderly patients (≥ 70 years of age with advanced non small cell lung cancer and poor performance status (PS ≥ 2 (clinical stage IIIb and IV , and as well to evaluate tolerability of this therapy. Secondary aim was to evaluate response rate.Methods Retrospectively, medical records of 79 female and male patients with advanced non small cell lung cancer and poor performance status treated with oral etoposide (2x25 mg 20 days/10 days pause in period from 2007 till 2010 were checked for relevant data. Data regarding demographics, performance status, overall survival, response rates and drug toxicity were collected. For statistical analysis we used Pearson chi-square test, T-test, Kaplan-Meier product limited method and Cox regression.Results Median overall survival (OS was 31 weeks, in patients with PS 2 overall survival was 34 weeks, and in group with PS 3 was only 24 weeks. Partial response was registered in 20.2% of patients, stable disease in 41.85 % and disease progression in 38% of patients. Treatment was well tolerated, febrile neutropenia and toxic deaths were not registered. Toxic effects didn't have statistically significant influence on OS.Conclusion Oral etoposide used as mono therapy has been shown as moderate effective and very safe in treating elderly patients with advanced non small cell lung cancer and poor performance status so it represents a good therapy option for treating this specific population.

  8. Tumor response and survival in patients with advanced non-small-cell lung cancer: the predictive value of chemotherapy-induced changes in fibrinogen

    International Nuclear Information System (INIS)

    Hyperfibrinogenemia is a common problem associated with various carcinomas, and is accompanied by hypercoagulablity. In advanced non-small-cell lung cancer (NSCLC) it remains unclear whether or not chemotherapy-induced changes in fibrinogen level relate to chemotherapeutic response and prognosis. The purposes of this study were to: 1) analyze the association between chemotherapy-induced changes in plasma fibrinogen level and the chemotherapeutic response after the first two courses of standard first-line platinum-based chemotherapy; and 2) evaluate the prognostic significance of the basal plasma fibrinogen level in patients with advanced NSCLC. In this retrospective study, the data from 160 patients with advanced NSCLC were collected. The association between the changes in fibrinogen and the response to chemotherapy, or between the pre-and post-chemotherapy fibrinogen levels and patient clinical characteristics, were analyzed using SPSS software. In addition, the prognostic value of pre-chemotherapy fibrinogen levels was assessed. The median pre-chemotherapy plasma fibrinogen level was 4.4 g/L. Pre-chemotherapy plasma fibrinogen levels correlated significantly with gender (p = 0.041). Post-chemotherapy plasma fibrinogen levels correlated with gender (p = 0.023), age (p = 0.018), ECOG (p = 0.002) and tumor response (p = 0.049). Plasma fibrinogen levels markedly decreased after chemotherapy in 98 (61.25 %) patients with pre-chemotherapy hyperfibrinogenemia (p = 0.008); and in this population there was a significant link between the decrease in fibrinogen level, and initial partial response (PR; p = 0.017) and stable disease (SD; p = 0.031). Univariate and multivariate analysis revealed that higher levels of fibrinogen (≥4.4 g/L) and ECOG 1 were positively associated with shorter overall survival (OS). CEA and CA125 also decreased significantly (p =0.015, p =0.000) in DCR group after chemotherapy. This study showed that the reduction in plasma fibrinogen levels

    Full Text Available Small-cell lung cancer (SCLC is one of the most aggressive lung tumors. The majority of patients with SCLC are diagnosed at an advanced stage. This tumor type is highly sensitive to chemo-radiation treatment, with very high response rates, but invariably relapses. At this time, treatment options are still limited and the prognosis of these patients is poor. A better knowledge of the molecular biology of SCLC allowed us to identify potential druggable targets. Among these, the MET/HGF axis seems to be one of the most aberrant signaling pathways involved in SCLC invasiveness and progression. In this review, we describe briefly all recent literature on the different molecular profiling in SCLC; in particular, we discuss the specific alterations involving c-MET gene and their implications as a potential target in SCLC.

  15. The efficacy of Chinese herbal medicine as an adjunctive therapy for advanced non-small cell lung cancer: a systematic review and meta-analysis.

    Full Text Available Many published studies reflect the growing application of complementary and alternative medicine, particularly Chinese herbal medicine (CHM use in combination with conventional cancer therapy for advanced non-small cell lung cancer (NSCLC, but its efficacy remains largely unexplored. The purpose of this study is to evaluate the efficacy of CHM combined with conventional chemotherapy (CT in the treatment of advanced NSCLC. Publications in 11 electronic databases were extensively searched, and 24 trials were included for analysis. A sum of 2,109 patients was enrolled in these studies, at which 1,064 patients participated in CT combined CHM and 1,039 in CT (six patients dropped out and were not reported the group enrolled. Compared to using CT alone, CHM combined with CT significantly increase one-year survival rate (RR = 1.36, 95% CI = 1.15-1.60, p = 0.0003. Besides, the combined therapy significantly increased immediate tumor response (RR = 1.36, 95% CI = 1.19-1.56, p<1.0E-5 and improved Karnofsky performance score (KPS (RR = 2.90, 95% CI = 1.62-5.18, p = 0.0003. Combined therapy remarkably reduced the nausea and vomiting at toxicity grade of III-IV (RR = 0.24, 95% CI = 0.12-0.50, p = 0.0001 and prevented the decline of hemoglobin and platelet in patients under CT at toxicity grade of I-IV (RR = 0.64, 95% CI = 0.51-0.80, p<0.0001. Moreover, the herbs that are frequently used in NSCLC patients were identified. This systematic review suggests that CHM as an adjuvant therapy can reduce CT toxicity, prolong survival rate, enhance immediate tumor response, and improve KPS in advanced NSCLC patients. However, due to the lack of large-scale randomized clinical trials in the included studies, further larger scale trials are needed.

    Treatment related death (TRD) is the worst adverse event in chemotherapy and radiotherapy for patients with cancer, the reports for TRDs were sporadically. We aimed to study TRDs in non-small cell lung cancer (NSCLC) patients treated with concurrent chemoradiotherapy (CCRT), and determine whether high radiation dose and newer chemotherapy regimens were associated with the risk of TRD. Data from randomized clinical trials for locally advanced/unresectable NSCLC patients were analyzed. Eligible studies had to have at least one arm with CCRT. The primary endpoint was TRD. Pooled odds ratios (ORs) for TRDs were calculated. In this study, a total of fifty-three trials (8940 patients) were eligible. The pooled TRD rate (accounting for heterogeneity) was 1.44% for all patients. In 20 trials in which comparison of TRDs between CCRT and non-CCRT was possible, the OR (95% CI) of TRDs was 1.08 (0.70–1.66) (P = 0.71). Patients treated with third-generation chemotherapy and concurrent radiotherapy had an increase of TRDs compared to those with other regimens in CCRT (2.70% vs. 1.37%, OR = 1.50, 95% CI: 1.09–2.07, P = 0.008). No significant difference was found in TRDs between high (≥ 66 Gy) and low (< 66 Gy) radiation dose during CCRT (P = 0.605). Neither consolidation (P = 0.476) nor induction chemotherapy (P = 0.175) had significant effects with increased TRDs in this study. We concluded that CCRT is not significantly associated with the risk of TRD compared to non-CCRT. The third-generation chemotherapy regimens may be a risk factor with higher TRDs in CCRT, while high dose radiation is not significantly associated with more TRDs. This observation deserves further study. PMID:27300551

  17. Non-small cell lung cancer: current status of chemoradiation for locally advanced disease and an update on susceptibility and prevention

    International Nuclear Information System (INIS)

    Locally advanced, inoperable non-small cell lung cancer (NSCLC) afflicts 40,000 patients yearly. The traditional treatment has been radiation therapy (RT) alone with 5 year survival rates averaging around 5%. Recent reports of randomized clinical trials using combined radiochemotherapy suggest significant improvement in survival compared to RT alone. These trials are difficult to evaluate because of differences in dose, timing and sequencing of both the chemotherapy (CT) and the RT. Dr. Byhardt will give an overview of the significant chemoradiation trials, especially with respect to the factors associated with reduction of local failure and distant metastasis. Dr. Tishler will review the biologic rationale of these regimens and make some prognostications about the potential role of new chemotherapy agents, new developments in RT dose-time-fractionation, and new RT technology in future radiochemotherapy trials. While progress continues to be made using the more traditional cancer treatment modalities, investigations in NSCLC epidemiology and prevention are providing new insights regarding susceptibility, etiology, failure risk stratification, and potential avenues of therapeutic intervention. Dr. Spitz will discuss NSCLC as a paradigm of an environmentally induced disease in which host susceptibility may be determined by genetically determined modulation of environmental exposures. A mutagen sensitivity assay can determine individuals at high risk for developing NSCLC if exposed to carcinogens such as those in cigarette smoke. This susceptibility may have prognostic implications that could influence choice of therapy. Highly susceptible individuals can also be selected for special counseling, smoking cessation, with consideration given to chemoprevention. Dr. Gritz will review major work done in this area

    Four decades of clinical research document the effectiveness of chemotherapy in patients with lung cancers. Chemotherapeutic agents can improve lung cancer symptoms, lengthen life in most patients with lung cancers, and enhance curability in individuals with locoregional disease when combined with surgery or irradiation. Chemotherapy's effectiveness is enhanced in patients with EGFR-mutant and ALK-positive lung cancers and can "rescue" individuals whose oncogene-driven cancers have become resistant to targeted agents. As immunotherapies become part of the therapeutic armamentarium for lung cancers, chemotherapeutic drugs have the potential to modulate the immune system to enhance the effectiveness of immune check point inhibitors. Even in this era of personalized medicine and targeted therapies, chemotherapeutic agents remain essential components in cancer care. PMID:24857127

  20. The role of circulating anti-p53 antibodies in patients with advanced non-small cell lung cancer and their correlation to clinical parameters and survival

    International Nuclear Information System (INIS)

    Lung cancer causes approximately one million deaths each year worldwide and protein p53 has been shown to be involved in the intricate processes regulating response to radiation and/or chemotherapeutic treatment. Consequently, since antibodies against p53 (anti-p53 antibodies) are associated with mutations within the p53 gene it seems likely that these antibodies could, hypothetically, be correlated with prognosis. Serum samples from patients with non-small cell lung cancer (NSCLC) admitted to the Department of Oncology, University Hospital, Uppsala, Sweden, during 1983–1996 were studied. Anti-p53 abs were measured using a sandwich ELISA (Dianova, Hamburg, Germany). The present study included 84 patients with stage IIIA-IV (advanced NSCLC). At least three serum samples from each patient were collected and altogether 529 serum samples were analysed for the presence of anti-p53 antibodies. The median value of anti-p53 antibodies was 0.06 (range 0 – 139.8). Seventeen percent of investigated NSCLC first serum samples (n = 84) expressed elevated levels of anti-p53 antibodies. Anti-p53 antibodies were not correlated to tumour volume or platelets. Survival analysis showed that anti-p53 antibodies were not associated with survival as revealed by univariate analysis (p = 0.29). However, patients with adenocarcinoma had a significantly poorer survival if they expressed anti-p53 antibodies (p = 0.01), whereas this was not found for patients with squamous cell carcinoma (p = 0.13). In patients where the blood samples were collected during radiation therapy, a statistically significant correlation towards poorer survival was found (p = 0.05) when elevated anti-p53 antibodies levels were present. No correlations to survival were found for serum samples collected prior to radiation therapy, during chemotherapy, or during follow-up. When anti-p53 antibodies were measured continuously, no increase in median anti-p53 values was observed the closer the individual patient come to

    The combination of gemcitabine plus paclitaxel has been proposed as an alternative to the platinum-based combinations for treatment of advanced non-small-cell lung cancer (NSCLC). However, conflicting results have been reported. This meta-analysis was performed to compare the activity, efficacy, and toxicity of gemcitabine plus paclitaxel versus carboplatin plus either gemcitabine or paclitaxel in patients with untreated advanced NSCLC. Randomized phase II and phase III clinical trials comparing gemcitabine plus paclitaxel with carboplatin plus gemcitabine or paclitaxel were collected from electronic databases (Medline, EMBASE, and the Cochrane Central Register of Controlled Trials), relevant reference lists, and abstract books. The published languages and years were not limited. Pooled odds ratios (ORs) were calculated for the 1-year survival rate (1-year SR), the overall response rate (ORR), and grade 3 and grade 4 toxicities. Four randomized controlled trials (2186 patients) were identified from 2051 reports. They were all published as full-text articles. No significant heterogeneity was detected in these studies. A significant difference in ORR favoring gemcitabine plus paclitaxel over carboplatin-based doublets was observed [OR = 1.20; 95% confidence interval (95% CI) = 1.02-1.42; P = 0.03], whereas the trend toward an improved 1-year SR was not significant (OR = 1.07; 95% CI = 0.91-1.26; P = 0.41). An increased risk of grade 3-4 toxicities for patients receiving carboplatin-based chemotherapy was statistically demonstrated. The gemcitabine plus paclitaxel combination showed an improved ORR and a better toxicity profile but a similar 1-year SR compared to carboplatin-based doublets. For nonplatinum-based chemotherapy, gemcitabine plus paclitaxel is a useful alternative. PMID:20703493

    Abstract The aim of this study was to investigate the efficacy and safety of the extended use of platinum-based doublet chemotherapy (PT-DC) plus endostatin in patients with advanced nonsmall cell lung cancer (NSCLC). We performed a retrospective analysis of 200 newly diagnosed advanced NSCLC patients who had received at least 1 cycle of endostatin plus PT-DC between September 2009 and November 2014. Of these patients, 155 received 4 or more cycles of therapy (the extended therapy group), while 45 received less than 4 cycles of therapy (the control group). Clinical tumor responses, progression-free survival (PFS), overall survival (OS), and toxicity profiles were recorded and retrospectively analyzed. In the extended therapy group, 67 patients (43.2%) achieved a best overall response rate of partial response (PR), while in the control group, 13 patients (28.9%) had a best overall response rate of PR. After a median follow-up of 15.9 months, the median PFS and OS were 8.0 and 23.1 months in the extended arm and 5.8 and 14.0 months in the control arm, respectively. There were statistically significant differences in median PFS and OS between these 2 arms. Hematologic and gastrointestinal toxicities occurred more frequently in the extended therapy group, but no statistically significant difference was detected in grade 3 to 4 toxicities overall between these 2 groups. In conclusion, extended treatment using endostatin combined with PT-DC can provide additional survival benefits and satisfactory toxicity profiles in previously untreated patients with NSCLC, which merits further evaluation in a larger prospective study.

  4. Anaplastic lymphoma kinase gene rearrangements in patients with advanced-stage non-small-cell lung cancer: CT characteristics and response to chemotherapy

    International Nuclear Information System (INIS)

    Few articles have been published on the imaging findings of anaplastic lymphoma kinase (ALK)-positive non-small-cell lung cancer (NSCLC). To investigate the radiological findings of ALK-positive NSCLC in the advanced stage, CT scans were examined. In addition, the response to chemotherapy was evaluated. Of the 36 patients with ALK-rearranged NSCLC, a mass and a nodule were identified in 17 (47.2%) and 16 (44.4%), respectively, indicating that more than 40% had a small-sized tumor. Overall, 31 (86.1%) patients had lymphadenopathy, seven (19.4%) had extranodal lymph node invasion, and three (8.3%) had lymphangitis. A pleural effusion was seen in 15 patients (41.7%). All but one patient had no ground-glass opacity (GGO) lesions, indicating that most ALK-positive tumors showed a solid growth pattern without GGO on CT. Twenty were evaluable for response to chemotherapy; 10 (50.0%) had a partial response (PR), nine (45.0%) had stable disease (SD), and one (5.0%) had progressive disease (PD) with first-line chemotherapy. With second-line chemotherapy, five (26.3%) had PR, 11 (57.9%) had SD, and three (15.8%) had PD. The five patients with PR were all treated by using crizotinib. Time to progression was 8.2 months with first-line chemotherapy, and 6.0 months with second-line chemotherapy. Advanced-stage ALK-positive tumors have a relatively aggressive phenotype, which cannot be inferred from the size of the tumor alone. ALK-positive patients have a good response to first-line cytotoxic drugs and to crizotinib as second-line therapy, but a relatively poor response to cytotoxic drugs as second-line therapy

  5. Analysis of long-term survival in patients treated with three-dimensional conformal radiotherapy for locally advanced non-small cell lung cancer

    International Nuclear Information System (INIS)

    Objective: To evaluate the prognostic factors of locally advanced non-small cell lung cancer (LA-NSCLC) treated with three dimensional conformal radiation therapy (3D CRT). Methods: In 106 patients with stage IIIa/IIIb NSCLC treated with 3DCRT from Nov 2000 to Mar 2004, 46 of them were treated with radiotherapy alone, 41 by concurrent chemoradiation, and 19 by sequential chemoradiation. The influence of related prognostic factors on survival was evaluated by univariate and multivariate analysis. The treatment outcome was analyzed by prognostic index model. Results: The 1-, 3- and 5- year overall survival rate was 50.0%, 22.2% and 15.5%, respectively, and the median survival time was 12 months. The univariate analysis showed that the following factors were significantly associated with the longer survival: female, good kamofsky performance status (KPS), squamous cell carcinoma, absence of supraclavicular lymph nodes, no smoking history, hemoglobin ≥130 g/L before treatment, N stage, the maximum diameter of tumor ≤5 cm, the volume of tumor ≤90 cm3, GTV ≤150 cm3 and the radiotherapy efficacy. However, multivariate analysis revealed that no smoking history, hemoglobin ≥130 g/L and GTV ≤150 cm3 were the independent risk factors for predicting the survival. Conclusions: Three dimensional conformal radiation therapy could be effective in the treatment of locally advanced NSCLC. No smoking history, hemoglobin ≥130 g/L and GTV ≤150 cm3 might be the independent risk factors for predicting the survival. Prognostic index model could improve the potential of multivariate analysis in predicting the survival of patients treated with radiotherapy for NSCLC. (authors)

    Full Text Available Our objective is to compare the cost-utility of icotinib and gefitinib for the second-line treatment of advanced non-small cell lung cancer (NSCLC from the perspective of the Chinese healthcare system.Model technology was applied to assess the data of randomized clinical trials and the direct medical costs from the perspective of the Chinese healthcare system. Five-year quality-adjusted life years (QALYs and incremental cost-utility ratios (ICURs were calculated. One-way and probabilistic sensitivity analyses (PSA were performed.Our model suggested that the median progression-free survival (PFS was 4.2 months in the icotinib group and 3.5 months in the gefitinib group while they were 4.6 months and 3.4 months, respectively, in the trials. The 5-year QALYs was 0.279 in the icotinib group and 0.269 in the gefitinib group, and the according medical costs were $10662.82 and $13127.57. The ICUR/QALY of icotinib versus gefitinib presented negative in this study. The most sensitive parameter to the ICUR was utility of PFS, ranging from $-1,259,991.25 to $-182,296.61; accordingly the icotinib treatment consistently represented a dominant cost-utility strategy.The icotinib strategy, as a second-line therapy for advanced NSCLC patients in China, is the preferred strategy relative to gefitinib because of the dominant cost-utility. In addition, icotinib shows a good curative effect and safety, resulting in a strong demand for the Chinese market.

    Pemetrexed, a novel multi-targeted agent established for the treatment of mesothelioma, has been under investigation for other malignancies, and in recent years particularly for non-small-cell lung cancer (NSCLC). In the present trial we investigated pemetrexed in combination with paclitaxel as front-line treatment in advanced or metastatic NSCLC. Our objectives were to determine the response rate, median and overall survival and toxicity. From April 2005 until May 2006, 51 patients with advanced or metastatic NSCLC were enrolled and 48 were considered evaluable. There were 39 males and nine females, median age 62 years (range 37-81 years), one patient stage IIIA N(2), 23 patients, IIIB and 24, stage IV. All patients had a cytologically- or histologically-confirmed diagnosis. Pemetrexed was administered at a standard dose of 500mg/m(2) and paclitaxel at an escalating dose starting at 135mg/m(2), then 150mg/m(2) and ending at a dose of 175mg/m(2); the level was increased every three patients. Both agents were administered on day 1, repeated every 3 weeks for six courses. A 39.6% partial response rate was observed with a median survival of 14 months. Toxicity was mild with 8.3% grade 3 and 4 neutropenia and other very mild hematologic and non-hematologic adverse reactions. The combination of pemetrexed and paclitaxel at doses of 500mg/m(2) and 175mg/m(2), respectively, has been shown to be an effective combination with very limited toxicity. PMID:17382431

    Background Gefitinib is widely used in patients with advanced non-small-cell lung cancer (NSCLC),in whom chemotherapy had failed.Previous trials reported inconsistent findings regarding the efficacy of gefitinib on overall survival (OS) and progression free survival (PFS).This study was to evaluate the effects of chemotherapy plus gefitinib versus chemotherapy alone on survival of patients with NSCLC.Methods We systematically searched Medline,EmBase,the Cochrane Central Register of Controlled Trials,reference lists of articles,and proceedings of major meetings for relevant literature.Randomized controlled trials (RCTs) comparing chemotherapy with and without gefitinib in the treatment of patients with advanced NSCLC were included in our analysis.The primary endpoints were OS and PFS.Results Of 182 relevant studies,12 were included in the final analysis,which consisted of 6844 patients with NSCLC.Overall,we noted that gefitinib therapy had an 8% improvement in the OS as compared to the gefltinib-free therapy,but this difference was not statistically significant (HR,0.92; 95% C/:0.85-1.00; P=0.051).Furthermore,gefltinib therapy had significantly longer PFS compared to gefitinib-free therapy (HR,0.72; 95% C/ 0.60-0.87,P=0.001).Patients receiving gefitinib therapy also had a more frequent objective response rate (ORR) than the control arm (OR,2.51; 95% C/,1.67-3.78,P <0.001).Rashes,diarrhea,dry skin,pruritus,paronychia,and abnormal hepatic function were more frequent in the gefitinib therapy group.Conclusions Treatment with gefitinib had a clear effect on PFS and ORR,and it might contribute considerably to the OS.Furthermore,there was some evidence of benefit for gefitinib therapy among patients with adenocarcinoma.

    Objective:To observe the effect of Brucea javanica oil emulsion combined with chemotherapy on the immune function of patients with advanced non-small cell lung cancer (NSCLC). Methods:One hundred and fifty-six patients with NSCLC were randomly divided into treatment group (n=82) treated with Brucea javanica oil emulsion combined with GP regimen chemotherapy and control group (n=74) only with GP regimen chemotherapy. The cellular immunity (CD3+, CD4+, CD8+, CD16+CD56+) and humoral immunity (IgG, IgA, IgM, C3, C4) before and after chemotherapy were tested by lfow cytometry (FCM) and biochemical method, respectively. The inlfuences of two treatment methods on the immune function were compared, and clinical efifcacy was evaluated. Results:The remission rates (RRs) were respectively 40.3% and 36.5% in treatment group and control group, without statistical difference (P>0.05). Compared with chemotherapy before, the cellular immune function after chemotherapy decreased in control group (P<0.05),whereas the levels of CD3+, CD4+, CD4+/CD8+ and CD16+CD56+increased signiifcantly in treatment group (P<0.05 orP<0.01). After chemotherapy, the cellular immune function in treatment group was obviously superior to that in control group, whereas there was no statistical signiifcance by comparison to humoral immune indexes between two groups. Conclusion:With similar efifcacy to control group, Brucea javanica oil emulsion combined with GP regimen chemotherapy can improve the cellular immune function of patients with advanced NSCLC and protect the chemotherapy-induced cellular immune function from damage to a certain extent.

  10. Feasibility study of DCs/CIKs combined with thoracic radiotherapy for patients with locally advanced or metastatic non-small-cell lung cancer

    International Nuclear Information System (INIS)

    The combination of dendritic cells (DCs) and cytokine-induced killer cells (CIKs) can induce the anti-tumor immune response and radiotherapy may promote the activity. We aimed to explore the feasibility of DCs/CIKs combined with thoracic radiotherapy (TRT) for patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC). In this study, patients with unresectable stage III/IV NSCLC and an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0–2 and previously receiving two or more cycles of platinum-based doublet chemotherapy without disease progression received TRT plus DCs/CIKs or TRT alone until disease progression or unacceptable toxicity. The primary endpoint was median progression-free survival (mPFS). In treatment group, patients received four-cycle autologous DCs/CIKs infusion starting from the 6th fraction of irradiation. From Jan 13, 2012 to June 30, 2014, 82 patients were enrolled, with 21 patients in treatment group and 61 in control group. The mPFS in treatment group was longer than that in control group (330 days vs 233 days, hazard ratio 0.51, 95 % CI 0.27–1.0, P < 0.05), and the objective response rate (ORR) of treatment group (47.6 %) was significantly higher that of control group (24.6 %, P < 0.05). There was no significant difference in disease control rate (DCR) and median overall survival (mOS) between two groups (P > 0.05). The side effects in treatment group were mild and there was no treatment-related deaths. The combination of DCs/CIKs with TRT could be a feasible regimen in treating locally advanced or metastatic NSCLC patients. Further investigation of the regimen is warranted

    Purpose: to determine the maximum tolerated dose (MTD) of gemcitabine every 2 weeks to a concurrent radiotherapy administered during an aggressive program of sequential and simultaneous radio-/chemotherapy for locally advanced, unresectable non-small cell lung cancer (NSCLC). Patients and methods: ten patients with histologically confirmed NSCLC were observed and treated in accordance with a combined radio-/chemotherapy protocol. This included two cycles of induction chemotherapy with gemcitabine (1,200 mg/m{sup 2}) and vinorelbine (30 mg/m{sup 2}) at days 1, 8 and 22, 29, followed by concurrent radiotherapy including [{sup 18}F] fluorodeoxyglucose positron emission tomography-(FDG-PET-) based target volume definition (2.0 Gy/d; total dose 66.0 Gy) and chemotherapy with gemcitabine every 2 weeks at days 43, 57, and 71. The initial dose was 300 mg/m{sup 2}. The dose of gemcitabine was increased by 100 mg/m{sup 2} until the MTD was realized. Three patients were enrolled for each dose level. Results: dose-limiting toxicity (DLT) was identified for the patient group receiving gemcitabine 500 mg/m{sup 2}, due to grade 2 esophagitis (next to grade 3) in all patients. 6 weeks after the completion of radio-/chemotherapy, most patients still presented treatment-induced esophagitis. In accordance with expected complications, such as esophagitis, dysphagia and odynophagia, the MTD was defined at this dose level, although no DLT grade 3 was reached. Conclusion: after induction chemotherapy, the MTD and frequency of gemcitabine in locally advanced NSCLC is 500 mg/m{sup 2} every 2 weeks during a maximum of 7 weeks of thoracic radiotherapy.

    Background and objective Recent studies have showed that combination of chemotherapy and radiotherapy might result in better outcome for locally advanced non-small cell lung cancer (NSCLC). The aim of this study is to determine the maximal tolerance dose (MTD) and efficacy of full-dose gemcitabine and oxaliplatin when given concurrently with 3-dimentional radiation therapy (3D-RT) for locally advanced NSCLC. Methods Oxaliplatin was administered at a fixed dose of 130 mg/m2, and gemcitabine was administered at a starting dose of 800 mg/m2 with an incremental dose gradient of 200 mg/m2 for 3 dose levels. MTD was defined as the immediate dose level lower than the dose at which dose-limiting toxicity (DLT) occurred in more than one-third of the patients. The chemotherapy was administered at 3-week cycle. The RT was given as 3-D conformal manner at a single daily dose of 2 Gy for 5 days per week. Results Twenty-two patients were evaluable and distributed to three different dose levels: 6 at level 1, 8 at level 2 and 8 at level 3. Pulmonary toxicity, esophageal and hematologic toxicity were the main DLT. Grade Ⅲ acute pulmonary toxicity occurred in one patient each at level 2 and level 3, both with V20>20%, and grade Ⅲ esophagitis in two patients at level 3. The MTD of gemcitabine in this study was 1000 mg/m2. The overall response rate was 75.0% (9/12). The 1- and 2-year survival rate was 70.0% and 30.5% respectively. The median time to progression was 8.7 months (range 5--11.8 months). Conclusion With reduced radiation volume, gemcitabine of 1000 mg/m2 in combination with oxaliplatin of 130 mg/m2 was effective and could be safely administered for NSCLC.

In accordance with expected complications, such as esophagitis, dysphagia and odynophagia, the MTD was defined at this dose level, although no DLT grade 3 was reached. Conclusion: after induction chemotherapy, the MTD and frequency of gemcitabine in locally advanced NSCLC is 500 mg/m2 every 2 weeks during a maximum of 7 weeks of thoracic radiotherapy. (orig.)

  14. Adaptive Radiotherapy for Locally Advanced Non–Small-Cell Lung Cancer Does Not Underdose the Microscopic Disease and has the Potential to Increase Tumor Control

    International Nuclear Information System (INIS)

    Purpose: To evaluate doses to the microscopic disease (MD) in adaptive radiotherapy (ART) for locally advanced non–small-cell lung cancer (NSCLC) and to model tumor control probability (TCP). Methods and Materials: In a retrospective planning study, three-dimensional conformal treatment plans for 13 patients with locally advanced NSCLC were adapted to shape and volume changes of the gross tumor volume (GTV) once or twice during conventionally fractionated radiotherapy with total doses of 66 Gy; doses in the ART plans were escalated using an iso-mean lung dose (MLD) approach compared to non-adapted treatment. Dose distributions to the volumes of suspect MD were simulated for a scenario with synchronous shrinkage of the MD and GTV and for a scenario of a stationary MD despite GTV shrinkage; simulations were performed using deformable image registration. TCP calculations considering doses to the GTV and MD were performed using three different models. Results: Coverage of the MD at 50 Gy was not compromised by ART. Coverage at 60 Gy in the scenario of a stationary MD was significantly reduced from 92% ± 10% to 73% ± 19% using ART; however, the coverage was restored by iso-MLD dose escalation. Dose distributions in the MD were sufficient to achieve a TCP >80% on average in all simulation experiments, with the clonogenic cell density the major factor influencing TCP. The combined TCP for the GTV and MD was 19.9% averaged over all patients and TCP models in non-adaptive treatment with 66 Gy. Iso-MLD dose escalation achieved by ART increased the overall TCP by absolute 6% (adapting plan once) and by 8.7% (adapting plan twice) on average. Absolute TCP values were significantly different between the TCP models; however, all TCP models suggested very similar TCP increase by using ART. Conclusions: Adaptation of radiotherapy to the shrinking GTV did not compromise dose coverage of volumes of suspect microscopic disease and has the potential to increase TCP by >40% compared

This molecular feature is more frequent in young patients, with no/light smoking habit and with adenocarcinoma pathological subtype. Crizotinib is a tyrosine kinase inhibitor, targeting ALK, ROS1, RON, and MET. The preclinical efficacy results led to a fast-track clinical development. The US Food and Drug Administration (FDA approval was achieved after the Phase I clinical trial in 2011 in ALK-rearranged advanced NSCLC progressing after a first-line treatment. In 2013, the randomized Phase III trial PROFILE-1007 confirmed the efficacy of crizotinib in ALK-rearranged NSCLC, compared to cytotoxic chemotherapy, in second-line setting or more. In 2014, the PROFILE-1014 trial showed the superiority of crizotinib in the first-line setting compared to the pemetrexed platinum doublet chemotherapy. The response rate was 74%, and the progression-free survival was 10.9 months with crizotinib. Based on these results, crizotinib received approval from the FDA and European Medicines Agency for first-line treatment of ALK-rearranged NSCLC. The various molecular mechanisms at the time of the progression (ALK mutations or amplification, ALK-independent mechanisms encourage performing re-biopsy at the time of progression under crizotinib. The best treatment strategy at the progression (crizotinib continuation beyond progression, switch to second-generation tyrosine kinase inhibitors, or cytotoxic chemotherapy depends on the phenotype of the progression, the

    Background: Disparities in lung cancer treatment and palliative care are well documented. However, the mechanisms underlying these disparities are not fully understood. In this study, we evaluated racial and ethnic differences in beliefs and attitudes about lung cancer treatment and palliative care among patients receiving a new diagnosis of lung cancer. Methods: Patients were recruited from four medical centers in New York City and surveyed about their beliefs regarding lung cancer care, including disease-directed treatments, palliative and end-of-life care, and fatalistic and spiritual beliefs. We used univariate and multiple regression analyses to compare the distribution of beliefs among minority (black and Hispanic) and nonminority patients. Results: Of the 335 patients, 21% were black, 20% were Hispanic, and 59% were nonminority. Beliefs about chemotherapy and radiotherapy were similar across the three groups (P > .05), whereas black patients were more likely to believe that surgery might cause lung cancer to spread (P = .008). Fatalistic beliefs potentially affecting cancer treatment were more common among both minority groups (P ≤ .02). No significant differences were found in attitudes toward clinician communication about cancer prognosis (P > .05). However, both blacks and Hispanics were more likely to have misconceptions about advance directives and hospice care (P ≤ .02). Conclusions: Similarities and differences in beliefs about disease-directed treatment were observed between minority and nonminority patients with lung cancer. Minority patients hold more fatalistic views about the disease and misperceptions about advance care planning and hospice care. Further research is needed to assess the impact of these beliefs on decisions about lung cancer care and patient outcomes. PMID:22700777

    Lung cancer is the leading cancer cause of death in the United States. Radiotherapy is an essential component of the definitive treatment of early-stage and locally-advanced lung cancer, and the palliative treatment of metastatic lung cancer. Proton beam therapy (PBT), through its characteristic Bragg peak, has the potential to decrease the toxicity of radiotherapy, and, subsequently improve the therapeutic ratio. Herein, we provide a primer on the physics of proton beam therapy for lung cancer, present the existing data in early-stage and locally-advanced non-small cell lung cancer (NSCLC), as well as in special situations such as re-irradiation and post-operative radiation therapy. We then present the technical challenges, such as anatomic changes and motion management, and future directions for PBT in lung cancer, including pencil beam scanning.

Currently, single tumor markers can not be used for screening purposes either in asymptomatic populations or in those at high risk of lung cancer. However,they have important clini-cal value in the differential diagnosis,therapy efficacy evaluation,monitoring of recurrence or metastasis,and prognosis of lung cancer. A lot of clinical evaluation of Dickkopf-1, plasma kallikrein, MicroRNA and other newly discovered markers of lung cancer should be done. In the future,the lung cancer markers with superb sensitivity and specificity should be actively explored.

    Immunotherapy has been studied for many years in lung cancer without significant results, making the majority of oncologists quite skeptical about its possible application for non-small cell lung cancer treatment. However, the recent knowledge about immune escape and subsequent 'cancer immunoediting' has yielded the development of new strategies of cancer immunotherapy, heralding a new era of lung cancer treatment. Cancer vaccines, including both whole-cell and peptide vaccines have been tested both in early and advanced stages of non-small cell lung cancer. New immunomodulatory agents, including anti-CTLA4, anti-PD1/PDL1 monoclonal antibodies, have been investigated as monotherapy in metastatic lung cancer. To date, these treatments have shown impressive results of efficacy and tolerability in early clinical trials, leading to testing in several large, randomized Phase III trials. As these results will be confirmed, these drugs will be available in the near future, offering new exciting therapeutic options for lung cancer treatment.

    Full Text Available Abstract Lung cancer is the number one cause of cancer death; however, no specific serum biomarker is available till date for detection of early lung cancer. Despite good initial response to chemotherapy, small-cell lung cancer (SCLC has a poor prognosis. Therefore, it is important to identify molecular markers that might influence survival and may serve as potential therapeutic targets. The review aims to summarize the current knowledge of serum biomarkers in SCLC to improve diagnostic efficiency in the detection of tumor progression in lung cancer. The current knowledge on the known serum cytokines and tumor biomarkers of SCLC is emphasized. Recent findings in the search for novel diagnostic and therapeutic molecular markers using the emerging genomic technology for detecting lung cancer are also described. It is believed that implementing these new research techniques will facilitate and improve early detection, prognostication and better treatment of SCLC.

    The immune system plays an important role in preventing and combating the growth of tumors. However, the tumor can escape immunosurveillance by exploiting a series of immune escape mechanisms that are developed to avoid autoimmunity. Among these mechanisms is the hijacking of immune checkpoints that are induced on T-cell activation. Immune checkpoint therapy, which targets regulatory pathways in T-cells to enhance antitumor immune responses, has led to important clinical advances and provided a new weapon against cancer. This therapy has elicited durable clinical responses and long-term survival, especially in a fraction of patients with advanced non-small cell lung cancer (NSCLC), and the activity seems relative to the expression status of tumor programmed cell death receptor ligand-1. Combinatorial approaches with other immune checkpoint inhibitors, chemotherapy, or targeting agents are being explored in ongoing clinical trials, which may improve the outcome in NSCLC.%免疫系统在预防和抵抗肿瘤生长中起着非常重要的作用。然而,肿瘤细胞会利用一系列本来是为了防止自身免疫的机制来避开免疫监视,如劫持与 T 细胞活化相关的免疫检查点等。目前,靶向 T 细胞调节通路上的免疫检查点以增强抗肿瘤免疫反应的治疗药物开发已经取得重要进展,并在临床治疗晚期非小细胞肺癌患者时导致出现了长期缓解例,疗效似与肿瘤细胞程序性死亡受体配体-1的表达相关。使用这类药物的联合治疗,包括与其他免疫检查点抑制剂、化疗药物和分子靶向药物等的联合治疗,现也在进行临床探索,有希望在将来改善非小细胞肺癌患者的预后。

It has been proven that, there was evidence of various survival benefits derived from erlotinib in patients with different clinical features, but the results are conflicting. The aim of this study is to identify novel predictive factors and explore the interactions between clinical variables as well as their impact on the survival of Chinese patients with advanced NSCLC heavily treated with erlotinib. Methods The clinical and follow-up data of 105 Chinese NSCLC patients referred to the Cancer Hospital and Institute, Chinese Academy of Medical Sciences from September 2006 to September 2009 were analyzed. Multivariate analysis of progressive-free survival (PFS was performed using recursive partitioning referred to as the classification and regression tree (CART analysis. Results The median PFS of 105 eligible consecutive Chinese NSCLC patients was 5.0 months (95%CI: 2.9-7.1. CART analysis was performed for the initial, second, and third split in the lymph node involvement, the time of erlotinib administration, and smoking history. Four terminal subgroups were formed. The longer values for the median PFS were 11.0 months (95%CI: 8.9-13.1 for the subgroup with no lymph node metastasis and 10.0 months (95%CI: 7.9-12.1 for the subgroup with lymph node involvement, but not over the second-line erlotinib treatment with a smoking history ≤35 packs per year. The shorter values for the median PFS were 2.3 months (95%CI: 1.6-3.0 for the subgroup with lymph node metastasis and over the second-line erlotinib treatment, and 1.3 months (95%CI: 0.5-2.1 for the subgroup with lymph node metastasis, but not over the second-line erlotinib treatment with a smoking history >35 packs per year. Conclusion Lymph node metastasis, the time of erlotinib administration, and smoking history are closely correlated with the survival of advanced NSCLC patients with first- to

    Full Text Available Most patients with lung cancer are diagnosed when they present with symptoms, they have advanced stage disease, and curative treatment is no longer an option. An effective screening test has long been desired for early detection with the goal of reducing mortality from lung cancer. Sputum cytology, chest radiography, and computed tomography (CT scan have been studied as potential screening tests. The National Lung Screening Trial (NLST demonstrated a 20% reduction in mortality with low-dose CT (LDCT screening, and guidelines now endorse annual LDCT for those at high risk. Implementation of screening is underway with the desire that the benefits be seen in clinical practice outside of a research study format. Concerns include management of false positives, cost, incidental findings, radiation exposure, and overdiagnosis. Studies continue to evaluate LDCT screening and use of biomarkers in risk assessment and diagnosis in attempt to further improve outcomes for patients with lung cancer.

  15. Gefitinib in Non Small Cell Lung Cancer

    2011-01-01

    Full Text Available Gefitinib is an oral, reversible, tyrosine kinase inhibitor of epidermal growth factor receptor (EGFR that plays a key role in the biology of non small cell lung cancer (NSCLC. Phase I studies indicated that the recommended dose of gefitinib was 250 mg/day. Rash, diarrhea, and nausea were the most common adverse events. The positive results obtained in early phase 2 clinical trials with gefitinib were not confirmed in large phase 3 trials in unselected patients with advanced NSCLC. The subsequent discovery that the presence of somatic mutations in the kinase domain of EGFR strongly correlates with increased responsiveness to EGFR tyrosine kinase inhibitors prompted phase 2 and 3 trials with gefitinib in the first line-treatment of EGFR-mutated NSCLC. The results of these trials have demonstrated the efficacy of gefitinib that can be now considered as the standard first-line treatment of patients with advanced NSCLC harbouring activating EGFR mutations.

    BCL-2 Associated athanogene 1 (BAG-1) and Xeroderma pigmentosum group D (XPD) are involved in the nucleotide excision repair pathway and DNA repair. We aimed to investigate whether polymorphisms in BAG-1 and XPD have effects on chemotherapy sensitivity and survival in patients with advanced non-small-cell lung cancer (NSCLC) treated with vinorelbine combined cisplatin (NP) regimen. A total of 142 patients with diagnosed advanced NSCLC were recruited in the current study. NP regimen was applied for all eligible patients. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used for BAG-1 (codon 324) and XPD (codons 312 and 751) genotyping. The treatment response was evaluated according to the RECIST guidelines. Progression-free survival (PFS) and overall survival (OS) were record as median and end point, respectively. As for BAG-1 codon 324, the chemotherapy sensitivity in NSCLC patients with CT genotype was 0.383 times of those with CC genotype (P < 0.05). With respect to XPD codon 751, the chemotherapy sensitivity in NSCLC patients with Lys/Gln genotype was 0.400 times of those with Lys/Lys genotype (P < 0.05). In addition, NSCLC patients carrying combined C/C genotype at codon 324 in BAG-1, Asp/Asp of XPD codon 312, and Lys/Lys of XPD codon 751 produced a higher efficacy of NP chemotherapy compared to those carrying mutation genotypes (all P < 0.05). Further, there were significant differences in PFS between patients with combined C/C genotype of BAG-1 codon 324, Lys/Lys genotype of XPD codon 751, and Asp/Asp genotype of XPD codon 312 and patients carrying BAG-1 codon 324 C/T genotype, XPD codon751 Lys/Gln genotype, and XPD codon312 Asp/Asn genotype (P < 0.05). Multivariate Cox regression analysis indicated that the combined wild-type of codon 324 XPD, codon 751 XPD, and codon 312 BAG-1 is the protective factor for OS and PFS, and clinical stages is the risk factor for OS and PFS. In conclusion, our research

    Full Text Available Abstract Objective: To explore the significance of epidermal growth factor receptor (EGFR gene mutations in targeted therapy for patients with advanced non-small cell lung cancer (NSCLC. Methods: One hundred and seventeen patients with advanced NSCLC admitted in Maternal and Child Health Care Center of Zibo City from Jan., 2011 to Jan., 2014 were performed with EGFR gene detection and then divided into 3 groups according to the detecting results. Patients in group A and group B were given oral gefitinib, 250 mg/d while patients in Group C with docetaxel, 75 mg/m2. Chemotherapy for 3 groups was discontinued until severe adverse reactions or disease progression occurred, or continuous treatment was considered to be unfavorable by the doctors, or patients asked for withdrawal from the study. The relationship between clinicopathological features and EGFR mutations were analyzed. The short-term and long-term efficacy and adverse drug reactions of 3 groups were observed. Results: Of the 31 cases with EGFR mutations, there were 16 cases (51.6% of mutations in exon 19, 14 (45.2% in exon 21 and 2 (6.45% in exon 18. No EGFR mutation was found in exon 20. EGFR mutations were associated with histological types of tumors and whether patients were smoking. The median follow-up time was 26 months and 62 patients were dead. None of CR was in 3 groups. The disease control rate (DCR in Group A was obviously higher than that in Group B ( χ 2 =9.382, P=0.002, which was also higher in Group C than that in Group B ( χ 2 =4.674, P=0.031. The 1-year survival rate in Group A was obviously higher than that in group B and group C ( P <0.05, or P<0.01 , which was prominently higher in Group C than that in Group B ( P <0.01 . The median progression-free survival (PFS and median overall survival (OS were the longest in Group A was and the shortest in Group B. The adverse reactions of two kinds of

    Full Text Available Background: Platinum-based doublet chemotherapy is the backbone of treatment in advanced non-small cell lung cancer (NSCLC however second-line treatment options are controversial particularly in patients with borderline performance status (PS of 2. The aim of this study was to compare efficacy and toxicity of weekly docetaxel versus gemcitabine in this clinical setting. Patients and methods: A total of 70 patients with advanced (stage IIIB, IV NSCLC entered this single institute study. Cases of this study had experienced disease progression after the first-line platinum-based doublet chemotherapy, with PS 0- 2 in “Eastern Cooperative Oncology Group” scale. They were randomly assigned by stratified blocks to receive docetaxel 35 mg/m2 (Arm A, n=34 or gemcitabine 1000 mg/m2 (Arm B, n=36 days 1, 8 and 15, every three weeks, for up to six cycles. Primary end point was progression free survival (PFS and secondary end points were objective response rate, disease control rate, median overall survival (OS and toxicity. Dose modification was permitted upon clinician’s discretion for each individual patient. Results: Median of PFS was 2.02 months in arm A and 2.63 months in arm B (HR= 1.279; 95% CI: 0.710-2.304, P= 0.551. Although median OS for arm A was numerically greater (9.2 months than arm B (8.3 months it was statistically non-significant (HR= 1.384; 95% CI: 0.632 to 2.809, P= 0.59. Objective response was higher in Arm B than that in Arm A (P= 0.20 but disease control rates were statistically different in both arms (P= 0.034. Statistically significant differences in term of leukopenia was seen in arm B (P= 0.013. Conclusion: This study, with limited number of cases, indicates that in advanced NSCLC, weekly docetaxel and gemcitabine are reasonable second-line treatment options with statistically similar effectiveness in terms of PFS and median OS with manageable toxicities in patients with PS 0-2.

  1. Role of survival post-progression in phase III trials of systemic chemotherapy in advanced non-small-cell lung cancer: a systematic review.

    Full Text Available BACKGROUND: In advanced non-small-cell lung cancer (NSCLC, with the increasing number of active compounds available in salvage settings, survival after progression to first-line chemotherapy seems to have improved. A literature survey was conducted to examine whether survival post-progression (SPP has improved over the years and to what degree SPP correlates with overall survival (OS. METHODS AND FINDINGS: Median progression-free survival (MPFS time and median survival time (MST were extracted in phase III trials of first-line chemotherapy for advanced NSCLC. SPP was pragmatically defined as the time interval of MST minus MPFS. The relationship between MPFS and MST was modeled in a linear function. We used the coefficient of determination (r(2 to assess the correlation between them. Seventy trials with 145 chemotherapy arms were identified. Overall, median SPP was 4.7 months, and a steady improvement in SPP was observed over the 20 years (9.414-day increase per year; p<0.001 in parallel to the increase in MST (11.253-day increase per year; p<0.001; MPFS improved little (1.863-day increase per year. Overall, a stronger association was observed between MST and SPP (r(2 = 0.8917 than MST and MPFS time (r(2 = 0.2563, suggesting SPP and MPFS could account for 89% and 25% of the variation in MST, respectively. The association between MST and SPP became closer over the years (r(2 = 0.4428, 0.7242, and 0.9081 in 1988-1994, 1995-2001, and 2002-2007, respectively. CONCLUSIONS: SPP has become more closely associated with OS, potentially because of intensive post-study treatments. Even in advanced NSCLC, a PFS advantage is unlikely to be associated with an OS advantage any longer due to this increasing impact of SPP on OS, and that the prolongation of SPP might limit the original role of OS for assessing true efficacy derived from early-line chemotherapy in future clinical trials.

    Non-small-cell lung cancer is the most common type of lung cancer and one of the leading causes of cancer-related death worldwide. For this reason, advances in diagnosis and treatment are urgently needed. With the introduction of new, highly innovative hybrid imaging technologies such as PET/CT, staging and therapy response monitoring in lung cancer patients have substantially evolved. In this review, we discuss the role of FDG PET/CT in the management of lung cancer patients and the importance of new emerging imaging technologies and radiotracer developments on the path to personalized medicine.

    The recent availability of crizotinib in clinical practice, for the treatment of patients with advanced non-small cell lung cancer (NSCLC) selected by the presence of anaplastic lymphoma kinase (ALK) rearrangement, has relevant implications for both the diagnostic phase and the treatment choices. In the United States, crizotinib was approved by the Food and Drug Administration (FDA) in 2011 for patients with ALK positivity detected by FDA-approved companion diagnostic test. As of January, 2014, the only FDA-approved diagnostic test is Vysis ALK Break-Apart FISH Probe Kit. In Europe, European Medicines Agency (EMA) approved crizotinib for ALK-positive patients in 2012, without specifying the type of test used for determining the positivity. FISH remains the reference technique for ALK determination, but, if fully validated, immunohistochemistry could challenge the current ALK screening practice. Given the robust evidence of activity of crizotinib in ALK-positive patients both pretreated and chemotherapy-naïve, and the favourable tolerability profile of the drug, many oncologists would prefer to administer the drug as early as possible. This is technically feasible in the United States, where crizotinib was approved well before the availability of the results of the randomized phase III trial comparing the drug with standard second-line chemotherapy, and the use of crizotinib in ALK-positive patients is not restricted to a specific line of treatment. On the contrary, in Europe, differently from the FDA decision, crizotinib cannot be used in chemotherapy-naïve patients. In both realities, a deeper knowledge of mechanisms of resistance, the role of repeated biopsies, the treatment strategy for patients experiencing disease progression with crizotinib, the choice of the best chemotherapy regimen are challenging topics for the management of ALK-positive patients in clinical practice.

A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published inJournal of Clinical Oncology, to patients seen in their own clinical practice.A 78-year-old woman with a 40-pack-year smoking history has been referred for treatment of advanced non-small-cell lung cancer. She presented with a persistent cough and worsening dyspnea on exertion. A chest x-ray followed by a chest computed tomography scan revealed a 3-cm right upper lobe mass along with a moderate-size pleural effusion. Pleural fluid cytology was positive for adenocarcinoma. A brain magnetic resonance imaging scan was negative. A reflex molecular profile, includingKRAS,EGFR,ALK,BRAF,HER2,RET,MET, andROS, did not reveal an actionable abnormality. Her past medical history includes diabetes, hypertension, and osteopenia. Her medications include a β-blocker, angiotensin-converting enzyme inhibitor, oral antidiabetic agent, calcium, and vitamin D. The laboratory evaluation is notable for a hemoglobin of 10.8 g/dL and a creatinine clearance of 36 mL/min. The other laboratories are within normal limits. She is somewhat limited by the shortness of breath but maintains an Eastern Cooperative Oncology Group performance status of 1. She is independent in all of her instrumental and basic activities of daily living and denies falls. She has been referred to discuss treatment options. PMID:27001591

  9. High plasma exposure to pemetrexed leads to severe hyponatremia in patients with advanced non small cell lung cancer receiving pemetrexed-platinum doublet chemotherapy

    International Nuclear Information System (INIS)

    Pemetrexed-platinum doublet therapy is a standard treatment for stage IIIb/IV nonsquamous non small cell lung cancer (NSCLC). While the regimen is associated with several grade ≥3 toxicities, hyponatremia is not a commonly reported adverse effect. Here we report an unusually high incidence of grade ≥3 hyponatremia in Indian patients receiving pemetrexed-platinum doublet, and the pharmacological basis for this phenomenon. Forty-six patients with advanced NSCLC were enrolled for a bioequivalence study of two pemetrexed formulations. All patients received the pemetrexed-platinum doublet for six cycles followed by single-agent pemetrexed maintenance until progression. Pharmacokinetic blood samples were collected at predefined time points during the first cycle and the concentration-time profile of pemetrexed was investigated by noncompartmental analysis. Hyponatremic episodes were investigated with serum electrolytes, serum osmolality, urinary sodium, and urine osmolality. Sixteen of 46 patients (35%) had at least one episode of grade ≥3 hyponatremia. Twenty-four episodes of grade ≥3 hyponatremia were observed in 200 cycles of doublet chemotherapy. Plasma exposure to pemetrexed was significantly higher in patients with high-grade hyponatremia than in those with low-grade or no hyponatremia (P=0.063 and P=0.001, respectively). Pemetrexed clearance in high-grade hyponatremia was quite low compared with normal and low-grade hyponatremia (P=0.001 and P=0.055, respectively). Median pemetrexed exposure in this cohort was much higher than that reported in the literature from Western studies. Higher exposure to pemetrexed is associated with grade ≥3 hyponatremia. The pharmacogenetic basis for higher exposure to pemetrexed in Indian patients needs further investigation

    Full Text Available This study aimed to evaluate the safety, tolerability and pharmacokinetics of the combination of oral vinorelbine with erlotinib using the conventional (CSV and metronomic (MSV dosing schedules in patients with advanced non-small cell lung cancer (NSCLC.This was an open-label, multiple dose-escalation phase I study. An alternating 3+3 phase I design was employed to allow each schedule to enroll three patients sequentially at each dose level. Thirty patients with Stage IIIB/IV NSCLC were treated with escalating doses of oral vinorelbine starting at 40 mg/m2 on day 1 and 8 in the CSV group (N = 16 and at 100 mg/week in the MSV group (N = 14. Erlotinib was administered orally daily.The maximum tolerated dose was vinorelbine 80 mg/m2 with erlotinib 100 mg in the CSV group and vinorelbine 120 mg/week with erlotinib 100 mg in the MSV group. Grade 3/4 toxicities included neutropenia (N = 2; 13% and hyponatremia (N = 1; 6% in the CSV group, and neutropenia (N = 5; 36% in the MSV group. Objective response was achieved in 38% and 29% in the CSV and MSV groups respectively. Vinorelbine co-administration did not significantly affect the pharmacokinetics of erlotinib and OSI-420 after initial dose. However, at steady-state, significantly higher Cmax, higher Cmin and lower CL/F of erlotinib were observed with increasing dose levels of vinorelbine in the CSV group. Significantly higher steady-state Cmin, Cavg and AUCss of erlotinib were observed with increasing dose levels of vinorelbine in the MSV group.Combination of oral vinorelbine with erlotinib is feasible and tolerable in both the CSV and MSV groups.ClinicalTrials.gov NCT00702182.

    Background: Preoperative concurrent chemoradiotherapy (CRT) is an accepted treatment for potentially resectable, locally advanced, non-small-cell lung cancer (NSCLC). We reviewed a decade of single institution experience with preoperative split-course CRT followed by surgical resection to evaluate survival and identify factors that may be helpful in predicting outcome. Methods and Materials: All patients treated with preoperative split-course CRT and resection at Rush University Medical Center (RUMC) between January 1999 and December 2008 were retrospectively analyzed. Endpoints included overall survival (OS), progression-free survival (PFS), local-regional progression-free survival (LRPFS), and distant metastasis-free survival (DMFS). Patient and treatment related variables were assessed for correlation with outcomes. Results: A total of 54 patients were analyzed, 76% Stage IIIA, 18% Stage IIIB, and 6% oligometastatic. The pathologic complete response (pCR) rate was 31.5%, and the absence of nodal metastases (pN0) was 64.8%. Median OS and 3-year actuarial survival were 44.6 months and 50%, respectively. Univariate analysis revealed initial stage (p < 0.01) and percent weight change during CRT (p < 0.01) significantly correlated with PFS/OS. On multivariate analysis initial stage (HR, 2.4; 95% CI, 1.18-4.90; p = 0.02) and percent weight change (HR, 0.79; 95% CI, 0.67-0.93; p < 0.01) maintained significance with respect to OS. There were no cases of Grade 3+ esophagitis, and there was a single case of Grade 3 febrile neutropenia. Conclusions: The strong correlation between weight change during CRT and OS/PFS suggests that this clinical parameter may be useful as a complementary source of predictive information in addition to accepted factors such as pathological response.

  16. [Lung cancer screening - risk stratification : Who should undergo screening?].

    2016-09-01

    Lung cancer is one of the leading causes of deaths in Europa and the USA. In approximately 75 % of lung cancer patients, bronchogenic carcinoma is detected at an advanced tumor stage; therefore, therapeutic options which aim at curing the disease in these patients are limited and treatment is mostly palliative. A relatively good prognosis is reserved for the minority of patients where the tumor is detected at an early stage and treatment is potentially curative. For this reason, early diagnosis of lung cancer could save lives. Retrospective analyses of the US national lung screening trial (NLST) showed that especially high-risk populations (e. g. higher age, positive smoking history, overweight and a positive family history for lung cancer) benefit most from lung cancer screening. Thus, the effectiveness of computed tomography (CT) screening can be improved by focusing on high-risk populations. This review article summarizes the risk stratification models of the large European and American screening studies and discusses possible future biomarkers for risk stratification. PMID:27495786

  17. Prognostic model for long-term survival of locally advanced non-small-cell lung cancer patients after neoadjuvant radiochemotherapy and resection integrating clinical and histopathologic factors

    International Nuclear Information System (INIS)

    Outcome of consecutive patients with locally advanced non-small cell lung cancer and histopathologically proven mediastional lymph node metastases treated with induction chemotherapy, neoadjuvant radiochemotherapy and thoracotomy at the West German Cancer Center between 08/2000 and 06/2012 was analysed. A clinico-pathological prognostic model for survival was built including partial or complete response according to computed tomography imaging (CT) as clinical parameters as well as pathologic complete remission (pCR) and mediastinal nodal clearance (MNC) as histopathologic factors. Proportional hazard analysis (PHA) and recursive partitioning analysis (RPA) were used to identify prognostic factors for survival. Long-term survival was defined as survival ≥ 36 months. A total of 157 patients were treated, median follow-up was 97 months. Among these patients, pCR and MNC were observed in 41 and 85 patients, respectively. Overall survival was 56 ± 4% and 36 ± 4% at 24 and 60 months, respectively. Sensitivities of pCR and MNC to detect long-term survivors were 38% and 61%, specificities were 84% and 52%, respectively. Multivariable survival analysis revealed pCR, cN3 category, and gender, as prognostic factors at a level of α < 0.05. Considering only preoperative available parameters, CT response became significant. Classifying patients with a predicted hazard above the median as high risk group and the remaining as low risk patients yielded better separation of the survival curves by the inclusion of histopathologic factors than by preoperative factors alone (p < 0.0001, log rank test). Using RPA, pCR was identified as the top prognostic factor above clinical factors (p = 0.0006). No long term survivors were observed in patients with cT3-4 cN3 tumors without pCR. pCR is the dominant histopathologic response parameter and improves prognostic classifiers, based on clinical parameters. The validated prognostic model can be used to estimate individual prognosis and

    Full Text Available Background and objective Vinorelbine plus cisplatin/carboplatin (NP is one of the standard combination chemotherapy regimen for advanced non-small cell lung cancer (NSCLC. The aim of this study is toinvestigate the relationship between expression of Stathmin and β-tubulin-Ⅲ in NSCLC biopsies and sensitivity to Vinorelbine, which would provide a basis of the proper medicine choice for the patients' tailored chemotherapy. Methods Western blot was used to investigate the expression of Stathmin and β-tubulin-Ⅲ protein in the biopsies from stage ⅢB-Ⅳ NSCLC patients. All the cases were divided into 4 groups according to the level of the two proteins, of which L represented both protein expressed lowly, B showed β-tubulin-Ⅲ lowly expressed group, while S showed Stathmin lowly, and H represented both protein highly expressed. At the same time, all the patients accepted NP chemotherapy for 2 or 4 cycles according to the responses to this regimen. The responses rate (RR, media survival time (MST, time to progress (TTP were observed. Results A total of 90 stage ⅢB-Ⅳ NSCLC patients were divided into 4 groups, 22 in L group, 23 in B and S group while 22 in H group respectively. The RR of the groups were 68.2%, 26.1%, 30.4% and 22.7% respectively.There were statistically significant differences between L group and other 3 groups (P <0.05. The MST were 377, 305, 321 and 271 days respectively, and the TTP were 240, 182, 190 and 166 days in the 4 groups. Statistically significant differences between L group and other 3 groups (P <0.05 can be seen in both MST and TTP. Conclusion The expression of β-tubulin-Ⅲ and Stathmin in advanced NSCLC biopsies had relationship with the sensitivity to NP chemotherapyregimen in the patients. Cases with high level of these two proteins would have poor responses to this cytotoxic drug.

    Full Text Available Background and objective Due to the various inter-individual differences in the biological characteristics of tumor cells, as well as issues on the efficacy, adverse reactions, and defects of existing drugs, we compared the clinical efficacy and toxicity of pemetrexed and gemcitabine combined with cisplatin for the treatment of previously untreated advanced non-small cell lung cancer (NSCLC. Methods 251 patients were randomly divided into pemetrexed combined with cisplatin group (PP group with 127 cases and gemcitabine combined with cisplatin group (GP group with 124 cases. PP group received pemetrexed 500 mg/m2 iv infusion d1 and cisplatin 75 mg/m2 iv infusion d1, whereas GP group received gemcitabine 1,000 mg/m2 iv infusion d1,8 and cisplatin 75 mg/m2 iv infusion d1. The treatment cycle was once every three weeks. In addition, folic acid, vitamin B12, and dexamethasone were administered in both groups. Results The total clinical effective rates in PP group and GP group were 25.20% and 17.74%, respectively. The total efficiencies of non-squamous cell carcinoma were 27.62% and 16.00%. The tumor progression duration in these two groups was 6.5 and 5.6 months, respectively. The median survival time in the two groups was 16.9 and 17.0 months, respectively, with 59.62% and 65.87% survival rates of 1 year and 27.28% and 27.93% survival rates of 2 years, respectively. The total efficacy of non-squamous cell carcinoma in the PP group was significantly higher than that in GP group. The results were statistically significant. However, there were no significant differences in total response rates, tumor progression duration, and median survival rates of 1 and 2 years. The rate of adverse reactions, including white blood cell reduction, lower platelet count, lower hemoglobin, and hair loss in the PP group was significantly lower than that in the GP group. The results were statistically significant. Conclusion The clinical efficacy of pemetrexed and

    Full Text Available To observe the early change of metabolic tumor heterogeneity during chemoradiotherapy and to determine its prognostic value for patients with locally advanced non-small cell lung cancer (NSCLC.From January 2007 to March 2010, 58 patients with NSCLC were included who were received 18F-fluorodeoxyglucose (18F-FDG PET/CT before and following 40 Gy radiotherapy with the concurrent cisplatin-based chemotherapy (CCRT. Primary tumor FDG uptake heterogeneity was determined using global and local scale textural features extracted from standardized uptake value (SUV histogram analysis (coefficient of variation [COV], skewness, kurtosis, area under the curve of the cumulative SUV histogram [AUC-CSH] and normalized gray-level co-occurrence matrix (contrast, dissimilarity, entropy, homogeneity. SUVmax and metabolic tumor volume (MTV were also evaluated. Correlations were analyzed between parameters on baseline or during treatments with tumor response, progression-free survival (PFS, and overall survival (OS.Compared with non-responders, responders showed significantly greater pre-treatment COV, contrast and MTV (AUC = 0.781, 0.804, 0.686, respectively. Receiver-operating-characteristic curve analysis showed that early change of tumor textural analysis serves as a response predictor with higher sensitivity (73.2%~92.1% and specificity (80.0%~83.6% than baseline parameters. Change in AUC-CSH and dissimilarity during CCRT could also predict response with optimal cut-off values (33.0% and 28.7%, respectively. The patients with greater changes in contrast and AUC-CSH had significantly higher 5-year OS (P = 0.008, P = 0.034 and PFS (P = 0.007, P = 0.039. In multivariate analysis, only change in contrast was found as the independent prognostic factor of PFS (HR 0.476, P = 0.021 and OS (HR 0.519, P = 0.015.The metabolic tumor heterogeneity change during CCRT characterized by global and local scale textural features may be valuable for predicting treatment response

    Background Platinum-based regimens are used as standard first-line chemotherapy in non-small cell lung cancer (NSCLC) patients.To study if pharmacogenetic approach may allow a tailored selection of platinum chemotherapy for advanced NSCLC,we performed a meta-analysis to compare chemosensitivity to platinum with different ERCC1 C118T/MDR1 C3435T single-nucleotide polymorphism (SNP).Methods Relevant studies were identified by searching the PubMed,Embase,Cochrane,OVID,Springer,EBSCO and CNKI databases.Inclusion criteria were patients with advanced NSCLC who received platinum-based chemotherapy,an evaluated polymorphism of ERCC/MDR1 and overall response rate.We excluded duplicate publications,letters and review articles.The RevMan 4.2 and STATA 11 package were used to do comprehensive quantitative assessment.Results A total of 11 studies were included in this meta-analysis.For studies evaluating ERCC1 C118T,test for heterogeneity was done (x2=13.41,P=0.1),and the odds ratio (OR) for the wild-type C/C genotype versus the heterozygous C/T and T/T genotypes was 1.50 (95% CI 1.09-2.06,P=-0.01).In four studies evaluating MDR1 polymorphism,test for heterogeneity was also done (x2=3.22,P=0.36),and the OR for the wild-type C/C genotype versus the heterozygous C/T and T/T genotypes was 2.30 (95% CI 1.44-3.68,P=0.0005).Conclusions The results indicated that platinum-based chemotherapy sensitivity was significantly associated with polymorphism of ERCC1 C118T and MDR1 C3435T SNP.In further perspective studies,the ERCC1/MDR1 SNPs might serve as simple and less invasive biomarkers for personalized chemotherapy with platinum-based anticancer drugs.

    Many studies have identified the prognostic and predictive value of proteins or peptides in lung cancer but most failed to provide strong evidence for their clinical applicability. The strongest predictive proteins seem to be fatty acid-binding protein heart (H-FABP), and the 8-peak mass spectrography signature of VeriStrat. When focusing on VeriStrat, a ‘VeriStrat good’ profile did not discriminate between chemotherapy and erlotinib. The ‘VeriStrat poor’ profile showed a better outcome to chemotherapy than to erlotinib. VeriStrat is a prognostic test and only the “poor profile” discriminates for the type of therapy that should be chosen. Whether it adds useful information in patients with advanced non-small cell lung cancer (NSCLC) and wild type EGFR mutations is still doubtful. The position of the VeriStrat test in clinical practice is still not clear and we are waiting for prospective studies where biomarker test are involved in clinical decision. PMID:25815290

    The tumor microenvironment (TME) represents a milieu that enables tumor cells to acquire the hallmarks of cancer. The TME is heterogeneous in composition and consists of cellular components, growth factors, proteases, and extracellular matrix. Concerted interactions between genetically altered tumor cells and genetically stable intratumoral stromal cells result in an "activated/reprogramed" stroma that promotes carcinogenesis by contributing to inflammation, immune suppression, therapeutic resistance, and generating premetastatic niches that support the initiation and establishment of distant metastasis. The lungs present a unique milieu in which tumors progress in collusion with the TME, as evidenced by regions of aberrant angiogenesis, acidosis and hypoxia. Inflammation plays an important role in the pathogenesis of lung cancer, and pulmonary disorders in lung cancer patients such as chronic obstructive pulmonary disease (COPD) and emphysema, constitute comorbid conditions and are independent risk factors for lung cancer. The TME also contributes to immune suppression, induces epithelial-to-mesenchymal transition (EMT) and diminishes efficacy of chemotherapies. Thus, the TME has begun to emerge as the "Achilles heel" of the disease, and constitutes an attractive target for anti-cancer therapy. Drugs targeting the components of the TME are making their way into clinical trials. Here, we will focus on recent advances and emerging concepts regarding the intriguing role of the TME in lung cancer progression, and discuss future directions in the context of novel diagnostic and therapeutic opportunities.

  7. Radon and lung cancer in Spain

    International Nuclear Information System (INIS)

    It is known that the incidence of lung cancer is related to inhalation of radon and radon daughters. However, the magnitude of the risk and its dependence upon physiological and environmental factors are still not well defined either experimentally or epidemiologically. Occupational studies of underground miners are the only available human epidemiological information to estimate the risk of exposure to radon daughters in the indoor environment. The results are shown of a study carried out to determine whether lung cancer mortality rates in Spain are significantly correlated with the average indoor radon levels. For this purpose, we have used indoor radon data generated from the national survey carried out in 1989. Lung cancer distribution by cities and deaths, by year of death and sex, were retrieved for each of the different provinces of Spain for the period 1960-1985, showing the evolution and changes in the incidence of lung cancer in the population. Data referring to the evolution of lung cancer for males and females from 1940 until 1985 are also shown. Since cigarette smoking has been linked to lung cancer the effect of smoking habits in the Spanish population was also considered in this analysis. The first results of this study establish no clear evidence of any substantial association between lung cancer mortality rates and indoor radon for males. However, a relationship was evident for females. (author)

    Full Text Available Lung cancer is the leading cause of cancer-related mortality worldwide. Despiting the great progress on target agents, majority of people who do not harbor a mutation could not get benefit from them. Immunotherapy, through stimulating the body's immune system to improve the antitumor immunity effect, has been a new therapeutic method for non-small cell lung cancer (NSCLC. Study had been reported that immune checkpoint molecules, including programmed death-1 (PD-1/PD-ligand (L 1 axis, are closedly related with cancer generation and development, and play a key role on clinical significance of NSCLC. Activation of PD-1/PD-L1 pathway contributes to tumor immune escape, and block PD-1/PD-L1 pathway can enhance endogenous antimuor immunity. Currently increasing clinical trials suggested that immune checkpoint inhibitors, including anti-PD-1 and anti-PD-L1 monoclonal antibodies turned out to be beneficial and safe in NSCLC. Here, we provide a review on the progress of PD-1/PD-L1 pathway and immune checkpoint inhibitors in NSCLC.

    need to spare surrounding critical structures. Evolving radiotherapy technologies, such as four-dimensional (4D image-based motion management, daily on-board imaging and adaptive radiotherapy based on volumetric images over the course of radiotherapy, have enabled us to deliver higher dose to target while minimizing normal tissue toxicities. The image-guided radiotherapy adapted to changes of motion and anatomy has made the radiotherapy more precise and allowed ablative dose delivered to the target using novel treatment approaches such as intensity-modulated radiation therapy, stereotactic body radiation therapy, and proton therapy in lung cancer, techniques used to be considered very sensitive to motion change. Future clinical trials using real time tracking and biological adaptive radiotherapy based on functional images are proposed.

    Full Text Available Lung cancer, the leading cause of cancer deaths in males for decades, has recently become one of commonest causes for women too. As women delay the start of their family, the co-existence of cancer and pregnancy is increasingly observed. Nevertheless, lung cancer during pregnancy remains a rather uncommon condition with less than 70 cases published in recent years. Non-small cell lung carcinoma is the commonest type accounting for about 85% of all cases. Overall survival rates are low. Chemotherapy and/or targeted treatment have been used with poor outcomes. The disease has been also found to affect the products of conception with no short- or long-term consequences for the neonate. This article is referring to a narrative review of lung cancers diagnosed in pregnant women around the world.

    Robot-assisted surgery using the da Vinci surgical system has attracted attention because of excellent operability without shaking by joint forceps under the clear vision of a three-dimensional high-definition camera in lung cancer surgery. Although this form of advanced medical care is not yet approved for insurance coverage, it is at the stage of clinical research and expected to be useful in hilar exposure, lymph node dissection, and suturing of the lung parenchyma or bronchus. Lung cancer surgery with the da Vinci system has the advantage of combining thoracotomy and minimally invasive surgery in video-assisted thoracic surgery. However, safety management, education, and significant cost are problems to be resolved. Several important issues such as sharing knowledge and technology of robotic surgery, education, training, development of new instruments, and acquisition of advanced medical insurance are discussed for the future development of robotic surgical systems.

    Full Text Available The pathologic diagnosis of lung cancer historically has relied primarily on morphologic features of tumors in histologic sections. With the emergence of new targeted therapies, the pathologist is called upon increasingly to provide not only accurate typing of lung cancers, but also to provide prognostic and predictive information, based on a growing number of ancillary tests, that may have significant impact on patient management. This review provides an overview of ancillary tests currently used in the pathologic diagnosis of lung cancer, with a focus on immunohistochemistry and molecular diagnostics.

    OBJECTIVES: Current British guidelines advocate the use of risk prediction scores such as Thoracoscore to estimate mortality prior to radical surgery for non-small cell lung cancer (NSCLC). A recent publication used the National Lung Cancer Audit (NLCA) to produce a score to predict 90day mortality...... (NLCA score). The aim of this study is to validate the NLCA score, and compare its performance with Thoracoscore. MATERIALS AND METHODS: We performed an internal validation using 2858 surgical patients from NLCA and an external validation using 3191 surgical patients from the Danish Lung Cancer Registry...

    Unexpected lung cancer is sometimes found in explanted lungs. The objective of this study was to review these patients and their outcomes to better understand and optimize management protocols for lung transplant candidates with pulmonary nodules. Retrospective analysis of pretransplant imaging and clinicopathologic characteristics of patients who were found to have lung cancer in their explanted lungs was performed. From January 2003 to December 2012, 13 of 853 lung transplant recipients were found to have unexpected lung cancer in their explanted lung (1.52%). Of them, 9 cases were for interstitial lung disease (2.8%; 9/321 recipients) and 4 cases were for chronic obstructive pulmonary disease (1.57%; 4/255 recipients). The median period between computed tomographic scan and lung transplantation was 2.40 months (range: 0.5-19.2). On computed tomographic scan, only 3 cases were shown to possibly have a neoplasm by the radiologist. The staging of these lung cancers was as follows: 3 cases of IA, 1 case of IB, 5 cases of IIA, 1 case of IIIA, and 3 cases of IV. Of 13 cases, 9 died owing to cancer progression. On the contrary, only 1 stage I case with small cell lung cancer showed cancer recurrence. The median survival time was 339 days, and the 3-year survival rate was 11.0%. In conclusion, most of the patients with unexpected lung cancer showed poor prognosis except for the early-stage disease. The establishment of proper protocol for management of such nodules is important to improve the management of candidates who are found to have pulmonary nodules on imaging. PMID:26074103
