    Full Text Available The last few years have witnessed an explosion of the use of minimally invasive techniques for the detection, diagnosis, and treatment of all stages of lung cancer. The use of these techniques has improved the risk-benefit ratio of surgery and has made it more acceptable to patients considering lung surgery. They have also facilitated the delivery of multi-modality therapy to patients with advanced lung cancer. This review article summarizes current surgical techniques that represent the "cutting edge" of thoracic surgery for lung cancer.

    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

    2013-04-01

    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.

    2015-12-01

    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

    Full Text Available Metastatic and recurrent tumors have been identified as the leading attribute to the lung cancer deaths. Cancer research has demonstrated the critical role circulating tumor cells (CTCs play in the metastatic spread of carcinomas and the recurrence of lung cancer. The rapid advancement of technology in targeted therapy resolves the embarrassing situation for those late-stage patients whose tumor tissues cannot be obtained. CTCs, as a substitute for the tumor tissues, represent a decisive tool to the cancer treatment strategy. Thus, CTCs exert a fundamental role in the early detection of micro-metastasis, assisting in diagnosis, prognosis and monitoring of the recurrent tumors, and subsequently choosing an individualized approach for the therapeutic treatment. This article will review the advances, which have been made in the research area of CTCs with the aid of its applications in cancer therapy.

    International Nuclear Information System (INIS)

    There will be over 160,000 cases of lung cancer diagnosed in the US in 1991, and deaths from this disease account for a quarter of all cancer deaths in this country. The incidence of lung cancer has continued to increase, especially among women. With 31% of American men and 25% of American women identified in the 1985 census as cigarette smokers, it is likely that this trend will continue well into the next century. Unfortunately, the majority of patients present with locally advanced tumors or distant metastatic disease. Presently, most patients with lung cancer will receive radiation therapy either in an attempt to control inoperable or locally advanced disease, or for palliation of symptomatic intrathoracic or metastatic disease. Because of the poor prognosis of all patients excepting those with early stage resectable lesions, lung cancer is appropriately the subject of intense clinical investigation and controversy throughout the world

    Lung cancer is the leading cause of death due to malignancy. Although lung cancer mortality has been decreasing in recent years, it remains substantially higher than other causes of cancer death. Median survival for patients with locally advanced non-small cell lung cancer, defined as lung cancer involving regional lymph nodes, is estimated to be approximately 10 to 17 months, and median survival for patients with metastatic disease is only 6 to 9 months. In addition, patients with advanced lung cancer often experience debilitating symptoms and poor quality of life. Pain, dyspnea, and fatigue are most frequently reported and affect at least 65% of patients with advanced lung cancer. Given this burden of symptoms and high mortality, patients and their families facing a diagnosis of advanced lung cancer are in need of support. Palliative care, with its focus on addressing the emotional, physical, and spiritual sources of suffering utilizing the expertise of an interdisciplinary team, can provide this comprehensive support. This review describes the role of supportive and palliative care integrated into the treatment of patients with a diagnosis of advanced lung cancer with sections focused on the evaluation and treatment of pain and dyspnea, approaches to challenging communication tasks, and the support of caregivers who care for patients 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.

    International Nuclear Information System (INIS)

    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

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.

    Full Text Available Globally, Lung cancer is the leading cause of cancer-related death of high morbidity and mortality with poor prognosis, which needs some more effective and less toxic therapies. The immunotherapies offer a novel approach for the treatment of patients with non-small cell lung cancer (NSCLC in both the adjuvant and palliative disease settings. A number of promising immunotherapies based on different mechanism have now been evaluated showing an increasing response rate. Moreover, further phase II/III clinical trials will be indicated to explore its value. These include checkpoint inhibitors (anti-CTLA4 antibody, anti-PD-1 antibody, anti-PD-L1 antibody, active vaccination (L-BLP25 liposome vaccine, Belagenpumatucel-L vaccine, MAGE-A3 protein vaccine and adoptive vaccination (CIK cells. The purpose of this paper will draw a summary on the theory, clinical trials, toxicity and problems to be solved of the immunotherapies in 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.

    There is a temporal disease-free period after 1st line chemotherapy in advanced non-small cell lung cancer (NSCLC), most of patients need 2nd line chemotherapy. The recommended drugs in the 2nd line were docetaxel, pemetrexed and epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). Single docetaxel is the established therapy for second-line treatment of NSCLC.Pemetexem was validated its indication in the 2nd line in advanced NSCLC through a phase III randomised clinical trial which was compared with docetaxel. Although there were little toxicity, the further research can't find the survival benefit in high dose pemetrexed. EGFR-TKIs target therapy is a hot spot now. Gefitinib and erlotinib monotherapy have a good efficacy in the 2nd line. The research of gefitinib versus traditional chemotherapy manifested that its efficacy was no less than docetaxel, and was less toxicitity . The comparison of erlotinib with chemotherapy is going on. There are more and more other drugs proved their effect in the 2nd line, such as the efficacy of oral toptecan and vinflunine were similar to docetaxel. PMID:20727256

    2010-03-01

    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.

  20. 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

  7. A comparison of tumor motion characteristics between early stage and locally advanced stage lung cancers

    International Nuclear Information System (INIS)

    Purpose: With the increasing use of conformal radiation therapy methods for non-small cell lung cancer (NSCLC), it is necessary to accurately determine respiratory-induced tumor motion. The purpose of this study is to analyze and compare the motion characteristics of early and locally advanced stage NSCLC tumors in a large population and correlate tumor motion with position, volume, and diaphragm motion. Methods and materials: A total of 191 (94 early stage, 97 locally advanced) non-small cell lung tumors were analyzed for this study. Each patient received a four-dimensional CT scan prior to receiving radiation treatment. A soft-tissue-based rigid registration algorithm was used to track the tumor motion. Tumor volumes were determined based on the gross tumor volume delineated by physicians in the end of expiration phase. Tumor motion characteristics were correlated with their standardized tumor locations, lobe location, and clinical staging. Diaphragm motion was calculated by subtracting the diaphragm location between the expiration and the inspiration phases. Results: Median, max, and 95th percentile of tumor motion for early stage tumors were 5.9 mm, 31.0 mm, and 20.0 mm, which were 1.2 mm, 12 mm, and 7 mm more than those in locally advanced NSCLC, respectively. The range of motion at 95th percentile is more than 50% larger in early stage lung cancer group than in the locally advanced lung cancer group. Early stage tumors in the lower lobe showed the largest motion with a median motion of 9.2 mm, while upper/mid-lobe tumors exhibited a median motion of 3.3 mm. Tumor volumes were not correlated with motion. Conclusion: The range of tumor motion differs depending on tumor location and staging of NSCLC. Early stage tumors are more mobile than locally advanced stage NSCLC. These factors should be considered for general motion management strategies when 4D simulation is not performed on individual basis.

    2011-12-01

    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

    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

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.

    Despite of recent development in the field of molecular targeted therapies, lung cancer is a leading cause of cancer death in the world. Remarkable progress has been made recently in immunotherapy for patients with non-small-cell lung cancer (NSCLC), with several modalities, concepts, and treatment settings being investigated. In vaccine development, large-scale clinical trials such as those with L-BLP25, belagenpumatucel-L, TG4010, and talactoferrin are already ongoing and some results have been reported. A trial of a vaccine as adjuvant therapy for patients with completely resected NSCLC is also ongoing with one of the major cancer-testis antigens, melanoma-associated antigen (MAGE)-A3. More recently, the effectiveness of multiple peptide vaccines has also been shown. Recently developed unique treatment modalities are the immune checkpoint inhibitors, such as antibodies against PD-1 and PD-L1, which also show promise. However, although therapeutic cancer vaccines are generally thought to be safe, severe adverse events should be monitored carefully when using immune checkpoint inhibitors. Here, we discuss recent advances and future perspectives of immunotherapy for patients with NSCLC. PMID:24196313

We present data for 12 (eight men, four women consecutive patients with 13 advanced non-small cell lung carcinomas in whom curative operations were contraindicated, who underwent PDT combined with chemotherapy for local control of the intraluminal lesions. The mean age was 73.3 years (range, 58–80 years, and the stages of cancer were IIA–IV. The median stenosis rates before treatment, one week post-treatment, and one month post-treatment were 60% (range, 30%–100%, 15% (range, 15%–99%, and 15% (range 15%–60%, respectively. The mean and median survival times were 9.3 and 5.9 months, respectively. The overall 1-year survival rate was 30.0%. No PDT-related morbidity or mortality occurred. In this single-institution study, all patients experienced improved symptoms and quality of life at one week after treatment; furthermore, an objective response was evidenced by the substantial increase in the openings of the bronchial lumen and prevention of obstructive pneumonia. Therefore, PDT with chemotherapy was useful and safe for the treatment of bronchial obstruction.

    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.

The aim of this study is to analyze the clinical data of women with advanced non-small cell lung cancer (NSCLC retrospectively to explore the prognostic factors. Methods Clinical data of 541 female patients with advanced NSCLC were collected and followed up till death. The primary endpoint is overall survival (OS. SPSS 11.0 statistical analysis software was used for univariate and multivariate analysis. Results The mean age is 59 years (20 years-86 years, adenocarcinoma account for 80.2% (434/541. The median OS was 15 months (95%CI: 13.87-16.13, and 1, 2, 5-year survival rates were 58.8%, 23.7% and 3.20% respectively. Univariate analysis showed that clinical stage, ECOG score, weight loss, clinical symptoms, liver/bone/brain metastasis and received more than one chemotherapy regimen, good response to the first-line chemotherapy, EGFR-TKI targeted therapy and radiotherapy treatment were significantly correlated with the OS and survival rate (P < 0.05. Combined with multivariate analysis, weight loss before treatment, ECOG score, received EGFR-TKI targeted therapy and response to first-line chemotherapy were independent prognostic factor for survival (P < 0.05. Conclusion There is a higher percentage of adenocarcinoma in female NSCLC. Weight loss before treatment, ECOG score, EGFR-TKI targeted therapy and response to first-line chemotherapy may become independent prognostic factors for survival of female patients with advanced NSCLC.

    2012-02-03

    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.

    Background Non-small cell lung cancer (NSCLC) represents 85% of all lung cancers. It is estimated that 60% of patients with NSCLC at time of diagnosis have advanced disease. The aim of this study was to investigate clinical and demographic prognostic factors of long term survival in patients with unresectable NSCLC. Methods We retrospectively reviewed data of 1,156 patients with NSCLC stage IIIB or IV who survived more than 60 days from the time of diagnosis and treated from August 1987 until March 2013 in the Oncology Department of Pulmonary Clinic of the General Hospital Papanikolaou. Initially univariate analysis using the log-rank test was conducted and then multivariate analysis using the proportional hazards model of Cox. Also Kaplan Meier curves were used to describe the distribution of survival times of patients. The level of significance was set at 0.05. Results The mean age at diagnosis was 62 years. About 11.9% of patients were women and 88.1% were male. The majority of cases were adenocarcinomas (42.2%), followed squamous (33%) and finally the large cell (6%). Unlike men, most common histological type among women was adenocarcinoma rather than squamous (63% vs. 10.9%). In univariate analysis statistically significant factors in the progression free survival (PFS) and overall survival (OS) were: weight loss ≥5%, histological type, line 1 drugs, line 1 combination, line 1 cycles and radio lung. Specifically radio lung gives clear survival benefit in the PFS and OS in stage IIIB (P=0.002) and IV (Pcell carcinoma recorded the shortest OS and PFS compared with adenocarcinoma (P=0.043 and P=0.016 respectively) and squamous cell carcinoma (P=0.021 and P=0.004 respectively). In multivariate analysis the same predictors were statistically significant except for line 1 drugs. Conclusions This study confirms the increased incidence of adenocarcinoma in women than in men and the aggressiveness of large cell carcinoma. It also underlines the vitality of factors

    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.

  12. Multidisciplinary management of the locally advanced unresectable non-small cell lung cancer

    International Nuclear Information System (INIS)

    Locally advanced (Stage III) non-small cell lung cancer (NSCLC) accounts for approximately one third of all cases of NSCLC. Few patients with locally advanced NSCLC present with disease amenable to curative surgical resection. Historically, these patients were treated with primary thoracic radiation therapy (RT) and had poor long term survival rates, due to both progression of local disease and development of distant metastases. Over the last two decades, the use of multidisciplinary approach has improved the outcome for patients with locally advanced NSCLC. Combined chemoradiotherapy is the most favored approach for treatment of locally advanced unresectable NSCLC. There are two basic treatment protocols for administering combined chemotherapy and radiation, sequential versus concurrent. The rationale for using chemotherapy is to eliminate subclinical metastatic disease while improving local control. Sequential use of chemotherapy followed by radiotherapy has improved median and long term survival compared to radiation therapy alone. This approach appears to decrease the risk of distant metastases, but local failure rates remain the same as radiation alone. Concurrent chemoradiotherapy has been studied extensively. The potential advantages of this approach may include sensitization of tumor cells to radiation by the administration of chemotherapy, and reduced overall treatment time compared to sequential therapy; which is known to be important for improving local control in radiation biology. This approach improves survival primarily as a result of improved local control. However, it doesn't seem to decrease the risk of distant metastases probably because concurrent chemoradiation requires dose reductions in chemotherapy due to increased risks of acute morbidity such as acute esophageal toxicity. Although multidisciplinary therapy has led to improved survival rates compared to radiation therapy alone and has become the new standard of care, the optimal therapy of

    Full Text Available Background and objective Bevacizumab is a recombinant humanized monoclonal IgG1 antibody that selectively binds to and neutralizes the biologic activity of human vascular endothelial growth factor (VEGF. Bevacizumab was approved by the U.S. Food and Drug Administration (FDA in October 2006 for use in combination withcarboplatin and paclitaxel for the initial treatment of patients with unresectable, locally advanced, recurrent, or metastatic,nonsquamous, non-small cell lung cancer (NSCLC. The aim of this study is to observe the safety of bevacizumab therapy in combination with chemotherapy in Chinese patients with NSCLC. Methods Patients with advanced non-squamous NSCLC were treated with Bevacizumab 15 mg/kg, d1, repeated every 21 days until PD; Plus paclitaxel 175 mg/m2, on dl and carboplatin AUC=6 on dl. The cycle was repeated every 21 days. Results One grade 3 epistaxis was observed in onepatient. One grade 4 thrombosis was observed in one patient. 3/4-grade epistaxis and thrombosis was the most significant adverse events. Other adverse effects, such as hemoptysis, hypertension and proteinuria, were not severe and could be well tolerated. Conclusion Most chemotherapy-naive patients with advanced non-squamous NSCLC treated with bevacizumab in combination with paclitaxel and carboplatin have little adverse effects that can be well tolerated.

  17. Optimal pharmacotherapeutic strategies for elderly patients with advanced non-small cell lung cancer.

    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

    2013-12-01

    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.

    There remains an extensive debate over lung cancer screening, with lobbying for and against screening for very compelling reasons. The National Lung Screening Trial, International Early Lung Cancer Program, and other major screening studies favor screening with low-dose CT scans and have shown a reduction in lung cancer-specific mortality. The increasing incidence of lung cancer and the dismal survival rate for advanced disease despite improved multimodality therapy have sparked an interest in the implementation of national lung cancer screening. Concerns over imaging workflow, radiation dose, management of small nodules, overdiagnosis bias, lead-time and length-time bias, emerging new technologies, and cost-effectiveness continue to be debated. The authors address each of these issues as they relate to radiologic practice. PMID:26846531

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.

    International Nuclear Information System (INIS)

    Between 1983 and 1990, 332 patients with non-small cell lung cancer (NSCLC) were referred to short-time, split-course palliative thoracic radiotherapy. The group consisted of patients with locally advanced (IIIo), unresectable cancer, not suitable for curative radiotherapy, asymptomatic or having only minimal symptoms related to intrathoracic tumor. The therapeutic plan involved two series of irradiation. Tumor dose delivered in each series was 20 Gy given in five daily fractions over five treatment days. There were four weeks interval between series. Of 332 patients initially qualified to thoracic radiotherapy only 170 patients received the treatment; the other 162 patients were not irradiated because of treatment refusal or logistic problems concerning therapy. They made the control group of the study, receiving the best possible symptomatic care. Twelve-month survivals in the radiotherapy and control groups were 32.4% and 9.3%, respectively; 24-month survivals 11.2% and 0%, respectively. Improvement of survival after palliative thoracic radiotherapy was observed only in patients with clinical stage IIIA and Karnofsky's performance status (KPS) ≥ 70. (orig.)

    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.

    Full Text Available Background: Small cell lung cancer is an aggressive subtype of lung cancer whereby about one-third of cases are complicated with bra­in metastases. However, cerebellar metastases are uncommon and contribute to less than 10% of brain metastases. Case: We report a 76-year-old Malay male, an active smoker who presented with dyspnea and occasional cough with hemoptysis for one week. He also pre­sented with headache and constitutional symptoms of malignancy. Clinical examination suggested the presence of right upper chest patholo­gy and positive left cerebellar signs. His condition deteriorated two days later and he passed away after failed attempts at resuscitation. Chest radiograph showed right upper lobe collapse, and brain magnetic resonance imaging showed metastatic lesion in the left cerebellum extending to the right cerebellum. Post-mortem findings revealed small cell lung cancer with cerebellar metastases. Conclusion: Small cell lung cancer patients with brain metastases deteriorate very rapidly, and the management is mainly supportive. Primary prevention through education is the best way to reduce the incidence of lung cancer. In addition, secondary prevention and screening should be undertaken at earlier stages of the disease, as some studies have shown that combined chemotherapy and radiotherapy improve prog­nosis of malignancies detected at early stage.

    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

  16. Prediction of radiation-induced lung toxicity in locally advanced non-small cell lung cancer treated with chemoradiotherapy by functional lung dose-volume histogram

    International Nuclear Information System (INIS)

    Objective: To investigate the correlation between functional lung dose-volume histogram (f-DVH) parameters and radiation-induced lung toxicity (RILT) in patients of locally advanced non-small cell lung cancer (NSCLC) treated with late-course accelerated hyperfractionated radiotherapy and chemotherapy, and to identify the excellent predictors of f-DVH and their reference thresholds. Methods: A total of 51 patients of NSCLC at stage Ⅲ underwent PET/CT/SPECT coregistered image guided radiotherapy. Philips Pinnacle3 planning system was used for delineation of the target volume and organs at risk so as to establish the three dimensional conformal radiotherapy or intensity-modulated radiotherapy treatment plans. The version 3.0 of the NCI Common Terminology Criteria for Adverse Events was used to evaluate the grade of RILT, and analyze the correlation of the DVH parameters of the total lung (TL), ipsilateral lung (IL), and functional lung (FL) and RILT, and to identify the excellent predictors. The median follow-up was 15 months. Results: During the follow-up, 10 cases of RILT (19.6%) ≥grade 2 were observed. Single factor analysis showed that the V5-V40 of TL, V5-V20 of IL, and V5-V50 of FL were all related to the occurrence of RILT, and multiple factor analysis showed that TL-V15 and FL-V20 remained associated with RILT (P=0.005 and P=0.016). According to ROC analysis, the V10 (45.38%) of FL was the most sensitive predictor with a sensitivity rate of 90.0% and 1/25 (27.78%) of FL was the most specific predictor with a specificity rate of 90.24%. The sensitivity, specificity and accuracy of V20 of FL were 70.00%, 73.17%, and 74.90%, respectively. Conclusions: The occurrence of RILT is closely associated with multiple f-DVH parameters of FL, and f-DVH has good sensitivity and specificity for prediction. (authors)

  17. Thermoradiotherapy in the Treatment of Locally Advanced Non small Cell Lung Cancer

    International Nuclear Information System (INIS)

    Purpose : To improve the treatment results of locally advanced non small cell lung cancer (NSCLC) patient, we treated those patients with regional hyperthermia combined with radiotherapy. And we conducted a retrospective analysis of the results.Methods and Materials : Thirty two non small cell lung cancer patients treated at the Department of Radiation Oncology, St. Mary's hospital. Catholic University Medical College were the base of this analysis. Fourteen patients of above them were treated with hyperthermia and radiotherapy of more than 3000 cGy in radiation dose. Radiofrequency capacitive hyperthermia was administered twice weekly, immediately after radiotherapy. Total sessions of hyperthermia ranged from 3 to 13 times (mean 7,8). Eighteen patient received an external radiation therapy alone. Median radiation dose was 5580 cGy (range, 3000-7000 cGy) in fraction of 180-300 cGy, 5 fractions per week.Results : The results of thermoradiotherapy group (HTRT group) were compared with radiation alone group (RT group). There were no complete response (CR) and 12 partial responses (PR) (CR rate 0%, response rate 85.7%) in HTRT group, whereas there were 2 CRs, 8 PRs and 8 no responses (CR rate 11.1%, response rate 55.6%) in RT group. There was significant difference in local response rate of the tumors between RT group and HTRT group (p<0.05). Overall 2 year survival rate and mean survival were 7.1% and 10.5 months for HTRT group, and 0% 8.1 months for RT group. However, by the number of hyperthermia, in cases with more than or equal to 10 sessions of hyperthermia, there were significant improvement in 2 year survival rate and mean survival (40.0% and 18.2 months) compared with those in cases with less than 10 sessions of hyperthermia (7.4% and 7.4 months) (p<0.05).Conclusion : Thermoradiotherapy in locally advanced NSCLC patients increased their response rate but not 2 year survival and mean survival, therefore thermoradiotherapy with enough number of hyperthermia is

    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.

  2. Molecular Predictors of EGFR-TKI Sensitivity in Advanced Non–small Cell Lung Cancer

    Directory of Open Access Journals (Sweden)

    Xiaozhu Zhang, Alex Chang

    2008-01-01

    Full Text Available The epidermal growth factor receptor (EGFR is overexpressed in the majority of non-small cell lung cancers (NSCLC and is a major target for new therapies. Specific EGFR tyrosine kinase inhibitors (TKIs have been developed and used for the treatment of advanced NSCLC. The clinical response, however, varies dramatically among different patient cohorts. Females, East Asians, non-smokers, and patients with adenocarcinoma usually show higher response rates. Meanwhile, a number of biological factors are also associated with EGFR-TKIs responsiveness. In order to better understand the predictive value of these biomarkers and their significance in clinical application we prepared this brief review. Here we mainly focused on EGFR somatic mutations, MET amplification, K-ras mutations, EGFRvIII mutation, EGFR gene dosage and expression, HER2 gene dosage and expression, and Akt phosphorylation. We think EGFR somatic mutation probably is the most effective molecular predictor for EGFR-TKIs responsiveness and efficacy. Mutation screening test can provide the most direct and valuable guidance for clinicians to make decision on EGFR-TKIs therapy.

    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

  4. AZD9291 in EGFR-mutant advanced non-small-cell lung cancer patients.

    Remon, Jordi; Planchard, David

    2015-11-01

    Non-small-cell lung cancer (NSCLC) patients whose tumors have an EGFR-activating mutation develop acquired resistance after a median of 9-11 months from the beginning of treatment with erlotinib, gefitinib and afatinib. T790M mutation is the cause of this resistance in approximately 60% of cases. AZD9291 is an oral, irreversible, mutant-selective EGF receptor (EGFR) tyrosine kinase inhibitor (TKI) developed to have potency against EGFR mutations, including T790M mutation, while sparing wild-type EGFR. A Phase I trial of AZD9291 in EGFR-mutant NSCLC patients, demonstrated high activity, essentially among T790M-mutant tumors, with a manageable tolerability profile. Ongoing Phase III trials are evaluating AZD9291 in EGFR-mutant patients as first-line treatment compared with erlotinib and gefitinib; and as second-line treatment compared with chemotherapy after progression on EGFR TKI in T790M-mutant tumors. Better identification of T790M-mutant tumors post EGFR TKI relapse and mechanisms of resistance to AZD9291 are the future challenges. This article reviews the emerging data regarding AZD9291 in the treatment of patients with advanced NSCLC. PMID:26450446

  6. 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

  7. 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.

  8. Dose escalation with stereotactic body radiation therapy boost for locally advanced non small cell lung cancer

    International Nuclear Information System (INIS)

    Low survival outcomes have been reported for the treatment of locally advanced non small cell lung cancer (LA-NSCLC) with the standard of care treatment of concurrent chemoradiation (cCRT). We present our experience of dose escalation using stereotactic body radiosurgery (SBRT) following conventional cCRT for patients with LA-NSCLC. Sixteen patients with a median age of 67.5 treated with fractionated SBRT from 2010 to 2012 were retrospectively analyzed. Nine (56%) of the patients had stage IIIB, 6 (38%) has stage IIIA, and 1 (6%) had recurrent disease. Majority of the patients (63%) presented with N2 disease. All patients had a PET CT for treatment planning. Patients received conventional cCRT to a median dose of 50.40 Gy (range 45–60) followed by an SBRT boost with an average dose of 25 Gy (range 20–30) given over 5 fractions. With a median follow-up of 14 months (range, 1–14 months), 1-year overall survival (OS), progression free survival (PFS), local control (LC), regional control (RC), and distant control (DC) rates were, 78%, 42%, 76%, 79%, and 71%, respectively. Median times to disease progression and regional failure were 10 months and 18 months, respectively. On univariate analysis, advanced age and nodal status were worse prognostic factors of PFS (p < 0.05). Four patients developed radiation pneumonitis and one developed hemoptysis. Treatment was interrupted in one patient who required hospitalization due to arrhythmias and pneumonia. Risk adaptive dose escalation with SBRT following external beam radiotherapy is possible and generally tolerated treatment option for patients with LA-NSCLC

    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.

    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.

  14. 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)

    Full Text Available Lung cancer is the leading cause of cancer-related mortality in both men and women and approximately 219,440 new cases of nonsmall cell lung cancer (NSCLC were estimated to occur in the USA in 2009, which caused 159,390 NSCLC-related deaths. More than 50% of cases of advanced NSCLC are diagnosed in patients older than age 65, and recent Surveillance Epidemiology and End Results (SEERs data suggest that the median age at diagnosis is 70 years. Until recently, the disease has been undertreated in this patient population, with a perception among many clinicians that elderly patients do not tolerate chemotherapy or radiotherapy. So, single agent chemotherapy is the recommended approach by the ASCO and International Expert Panels in unselected patients. The introduction of novel targeted therapies, such as Epidermal Growth Factor Receptor (EGFR Tyrosine Kinase Inhibitors (TKIs which improved survival versus placebo in patients who had previously failed on chemotherapy, gives clinicians new, effective, and better tolerated options to consider when treating NSCLC in elderly patients. This paper describes the advances of EGFR TKIs for elderly patients with advanced NSCLC.

    International Nuclear Information System (INIS)

    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.

    Full Text Available Seigo Minami,1 Takashi Kijima2 1Department of Respiratory Medicine, Osaka Police Hospital, 2Department of Respiratory Medicine, Allergy and Rheumatic Diseases, Osaka University Graduate School of Medicine, Osaka, Japan Abstract: Pemetrexed, a multitargeting antifolate cytotoxic drug, plays a leading role in front-line chemotherapy for patients with advanced non-squamous non-small-cell lung cancer (NSCLC. Following its approval as second-line monotherapy for locally advanced or metastatic non-squamous NSCLC, pemetrexed has established itself as the first-line regimen in combination with cisplatin, and its powerful antitumor effects and less cumulative toxicities were then taken advantage of in the JMEN and PARAMOUNT trials, respectively, to pioneer a new treatment strategy of switch and continuation maintenance monotherapy. These developments have brought about a marked paradigm shift, and made pemetrexed indispensable in the treatment for non-squamous NSCLC. So far, only three drugs have been approved for maintenance therapy; pemetrexed both by switch and continuation maintenance, erlotinib by switch maintenance, and bevacizumab by continuation maintenance. Compared with observation alone after defined cycles of the first-line chemotherapy, subsequent pemetrexed maintenance therapy has provided significantly longer survival and infrequent severe adverse events. The cost-effectiveness of pemetrexed maintenance therapy is controversial, as well as the other two maintenance drugs, bevacizumab and erlotinib. The latest attractive attention is a combination maintenance therapy. We may have to consider epidermal growth factor receptor (EGFR mutation status for selection of a combination pattern. A combination maintenance therapy of pemetrexed plus bevacizumab is potential for patients with wild-type EGFR status, while a EGFR tyrosine kinase inhibitor-containing combination is promising for patients with active EGFR mutation status. Pemetrexed will be

    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

    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.

    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

  17. 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)

    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.

    Objective: To assess the therapeutic effectiveness of preoperative neoadjuvant chemotherapy using a combination of paclitaxel and carboplatin on local advanced non-small cell lung cancer (NSCLC). 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.

  4. Physical treatment of lung cancer

    International Nuclear Information System (INIS)

    Trend of physical treatment and its outcome of lung cancer are described together with authors' experience. In locally advanced non-small cell lung cancer (NSCC) at stages IIIA and B, radiotherapy, chemotherapy (CT) and their combined therapy (RCT) have been major mainly in US since 1980s. After phase I/II trials of RCT by Okayama Lung Cancer Study Group where 5-year survival with nondisease is shown to be 31% (2003), phase III trial has been performed with results to be reported in 2008. A similar study by West Japan Oncology Group is now in summary. The secondary carcinogenesis not by radiation post RCT has become a problem: 10 years after, reportedly 61% incidence. Concerning the choice and regimen of CT medicals, there are many discussions. In recurrent/advanced NSCC, inhibitors of epidermal growth factor receptor tyrosine kinase (RTK) (gefitinib and recently, erlotinib) will be further useful, and molecular target medicals like an anti-vascular endothelial growth factor antibody (bevacizumab) and other novel RTK inhibitors will be also promising. In small cell lung cancer (SCC), efficacy 50% of amrubicin has been reported in a phase II trial recently. Prophylactic cranial irradiation in the extensive cases has been recognized effective also recently. CT studies with a large dose of anti-cancer drugs of SCC are still under progress. Along with the introduction of many molecular target drugs, physical treatment of lung cancer is to be bright in future. (R.T.)

    Recent presentations at the American Society of Clinical Oncology (ASCO) meeting from 30 May to 3 June, 2014, will impact routine clinical care and the development of clinical trials in non-small cell lung cancer (NSCLC) and extensive stage small cell lung cancer (ES-SCLC). Patients with activating epidermal growth factor receptor (EGFR) mutations, defined as exon 19 and exon 21 L858R point mutations, experience a high objective response rate and prolonged progression-free survival with EGFR tyrosine kinase inhibitors. However, inevitably, patients experience disease progression and the most common mechanism of acquired resistance is an EGFR exon 20 T790M mutation. Several agents (AZD9291, CO-1686 and HM61713) have demonstrated impressive activity in patients with T790M resistance mutations. Additional data on the efficacy of first-line therapy with afatinib and the combination of erlotinib and bevacizumab for patients with EGFR mutant NSCLC were presented. The results of a phase III trial of crizotinib compared to platinum-pemetrexed in the first-line setting, and a phase I trial and expansion cohort of ceritinib, provided additional efficacy and toxicity data for patients with anaplastic lymphoma kinase rearranged NSCLC. A phase III trial of cisplatin and gemcitabine, with and without necitumumab, revealed an improvement in overall survival with the addition of necitumumab in patients with squamous NSCLC. In the second-line setting, a phase III trial of docetaxel with ramucirumab or placebo revealed an improvement in overall survival with the addition of ramucirumab. In extensive stage small cell lung cancer phase III trials of consolidative thoracic radiation therapy and prophylactic cranial radiation failed to reveal an improvement in overall survival.

    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

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.

    Full Text Available Recently, several reports have suggested that HMGB1 (the high-mobility group box-1 plays a key role in tumor angiogenesis through multiple mechanisms, including up-regulation of proangiogenic factors. This study was conducted to investigate the prognostic role and the effects of chemotherapy on serum (ELISA angiogenic factors: HMGB1, survivin and VEGF (Vascular Endothelial Growth Factor in patients with advanced stage non-small cell lung cancer (NSCLC. The study entered 40 patients (31 man and 15 healthy volunteers (control group. Peripheral blood samples were taken before and after four cycles of chemotherapy. The mean serum HMGB1 and VEGF levels were significantly higher in patients with advanced NSCLC than in controls (p=0.024, p=0.028, respectively. The levels of survivin in NSCLC patients were comparable to controls. No correlation was found between HMGB1, survivin and VEGF concentrations and the histological type and staging of lung cancer. Similarly, no correlation was revealed between the concentrations of HMGB1, survivin and VEGF and the effect of chemotherapy. However, in patients with NSCLC, HMGB1 positevely correlated with survivin (R=0.814, p=0.007 before chemotherapy, and negatively with VEGF (R=-0.841, p=0.035 after chemotherapy. When the cut-off values of serum HMGB1, survivin and VEGF (2.38 ng/ml, 81.92 pg/ml, 443.26 pg/ml, respectively were used, the prognoses of high and low groups were not different. Concluding, patients with NSCLC have a higher serum concentration of HMGB1 and VEGF, while survivin levels are comparable to healthy individuals. In our opinion, determination of HMGB1, survivin and VEGF concentrations has no clinical significance in the prognosis of the survival time in lung cancer.

    As cancer care becomes increasingly complex, the ability to coordinate this care is more difficult for health care providers, patients and their caregivers alike. Despite the widely recognized need for improving continuity and coordination of care, the relationship of continuity of care with patient outcomes has yet to be elucidated. Our study's main finding is that the Continuity and Coordination subscale of the widely used Picker System of Ambulatory Cancer Care Survey is able to distinguish between lung cancer patients with unmet supportive care needs and those without. Specifically, this study shows a new association between this widely implemented continuity and coordination survey and the 'psychological needs' domain, as well as the 'health system and information' domains of supportive care needs. The finding provides support for the idea that interventions to improve continuity may impact tangible indicators of patient care such as supportive care needs being met. The study focuses attention on continuity of care as an important aspect of optimizing outcomes in cancer care. PMID:23274923

  14. Intensity-Modulated Radiotherapy for Locally Advanced Non-Small-Cell Lung Cancer: A Dose-Escalation Planning Study

    International Nuclear Information System (INIS)

    Purpose: To evaluate the potential for dose escalation with intensity-modulated radiotherapy (IMRT) in positron emission tomography-based radiotherapy planning for locally advanced non-small-cell lung cancer (LA-NSCLC). Methods and Materials: For 35 LA-NSCLC patients, three-dimensional conformal radiotherapy and IMRT plans were made to a prescription dose (PD) of 66 Gy in 2-Gy fractions. Dose escalation was performed toward the maximal PD using secondary endpoint constraints for the lung, spinal cord, and heart, with de-escalation according to defined esophageal tolerance. Dose calculation was performed using the Eclipse pencil beam algorithm, and all plans were recalculated using a collapsed cone algorithm. The normal tissue complication probabilities were calculated for the lung (Grade 2 pneumonitis) and esophagus (acute toxicity, grade 2 or greater, and late toxicity). Results: IMRT resulted in statistically significant decreases in the mean lung (p <.0001) and maximal spinal cord (p = .002 and 0005) doses, allowing an average increase in the PD of 8.6-14.2 Gy (p ≤.0001). This advantage was lost after de-escalation within the defined esophageal dose limits. The lung normal tissue complication probabilities were significantly lower for IMRT (p <.0001), even after dose escalation. For esophageal toxicity, IMRT significantly decreased the acute NTCP values at the low dose levels (p = .0009 and p <.0001). After maximal dose escalation, late esophageal tolerance became critical (p <.0001), especially when using IMRT, owing to the parallel increases in the esophageal dose and PD. Conclusion: In LA-NSCLC, IMRT offers the potential to significantly escalate the PD, dependent on the lung and spinal cord tolerance. However, parallel increases in the esophageal dose abolished the advantage, even when using collapsed cone algorithms. This is important to consider in the context of concomitant chemoradiotherapy schedules using IMRT.

    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.

    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.

    Non-small cell lung cancer (NSCLC) is one of the most deadly cancers worldwide, with poor prognosis once the disease has progressed past the point at which surgery is a viable option. Whilst chemotherapy has improved survival over recent decades, there is still great need for improvements in treatments for patients with advanced disease. Over the last decade, a variety of such drugs have received market approval for treating NSCLC, with a variety of others in the pipeline. Here, we review the development of targeted therapies for the treatment of advanced or metastatic NSCLC, including those already in clinical practice and those in early trials. The epidermal growth factor receptor (EGFR) inhibitors, gefitinib, erlotinib and afatinib; the anaplastic lymphoma kinase (ALK) inhibitor, crizotinib; and the anti-vascular endothelial growth factor receptor monoclonal antibody, bevacizumab, are already providing improved survival for patients with NSCLC. Moreover, the discovery of EGFR mutations and ALK rearrangements has enabled the identification of patients who are more likely to benefit from a specific drug. The recent approval of the immune checkpoint inhibitor nivolumab, along with the designation of alectinib and MPDL3280A as breakthrough therapies by the FDA, demonstrates how rapidly this area of research is expanding. Over the last decade there has been significant progress made in the treatment of advanced NSCLC, and the large and varied selection of drugs currently undergoing trials provide great promise for improving the prognosis of this highly prevalent and deadly form of cancer.

    Lung cancer is the most common cancer worldwide with non-small cell lung cancer (NSCLC), including squamous carcinoma, adenocarcinoma and large cell carcinoma, accounting for about 85% of all lung cancer types with most of the patients presenting with advanced disease at the time of diagnosis. In this setting first-line platinum-based chemotherapy for no more than 4-6 cycles are recommended. After these cycles of treatment, non-progressing patients enter in the so called "watch and wait" period in which no further therapy is administered until there is disease progression. In order to improve the advanced NSCLC outcomes, the efficacy of further treatment in the "watch and wait" period was investigated. This is the "maintenance therapy". Recently, the results coming from randomized phase III trials investigating two new agents, pemetrexed and erlotinib, in this setting led to their registration for maintenance therapy. Here, we report and discuss these results. PMID:21129607

    Cancer vaccines contain tumor antigens in a pro-inflammatory context with the purpose to generate potent antitumor immune responses. However, tumor cells develop different immunosuppressive mechanisms that limit the effectiveness of an anticancer immune response. Therefore, therapeutic vaccine treatment alone is usually not sufficient to generate tumor regression or survival improvement, especially in the advanced disease scenario in which most clinical studies have been conducted. Combining cancer vaccines with different anticancer therapies such as chemotherapy, radiotherapy and other immunotherapeutic agents has had different levels of success. However, the combination of cancer vaccines with different mechanisms of action has not been explored in clinical trials. To address this issue, the current review summarizes the main clinical and immunological results obtained with two different therapeutic vaccines used in advanced non-small-cell lung cancer patients, inducing an immune response against epidermal growth factor (CIMAvax-EGF) and NGcGM3 ganglioside (racotumomab). We also discuss preliminary findings obtained in a trial of combination of these two vaccines and future challenges with these therapies. PMID:24777612

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.Keywords: erlotinib, tyrosine kinase inhibitors, first line, maintenance, non-small-cell lung cancer

    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.

    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

    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

  10. 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

    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

    2015-01-01

    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...

    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

  15. 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

    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.

    The tyrosine kinase inhibitors (TKI) against epidermal growth factor receptor (EGFR) are widely used in patients with non-small cell lung cancer (NSCLC). However, EGFR T790M mutation leads to resistance to most clinically available EGFR TKIs. Third-generation EGFR TKIs against the T790M mutation have been in active clinical development. These agents include osimertinib, rociletinib, HM61713, ASP8273, EGF816, and PF-06747775. Osimertinib and rociletinib have shown clinical efficacy in phase I/II trials in patients who had acquired resistance to first- or second-generation TKIs. Osimertinib (AZD9291, TAGRISSO) was recently approved by FDA for metastatic EGFR T790M mutation-positive NSCLC. HM61713, ASP8237, EGF816, and PF-06747775 are still in early clinical development. This article reviews the emerging data regarding third-generation agents against EGFR T790M mutation in the treatment of patients with advanced NSCLC. PMID:27071706

  5. Clinical investigation of weekly carboplatin and paclitaxel with concurrent radiation therapy for locally advanced non-small cell lung cancer

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate retrospectively chemotherapy of weekly carboplatin and paclitaxel with concurrent radiation therapy for patients with locally advanced non-small cell lung cancer (NSCLC). Between January 2000 and March 2008, 38 patients were treated by chemotherapy with carboplatin and paclitaxel once a week, repeated for 6 weeks, with thoracic radiation therapy of 1 or 2 times a day on weekdays. After concurrent chemoradiotherapy, we planned consolidation chemotherapy of carboplatin (area under the curve (AUC) 5-6) and weekly paclitaxel (70-80 mg/m2) on day 1, 8 and 15, when possible. The enrolled patients were 31 men and 7 women, with the median age of 59 years (39-76 years), stage IIIA/IIIB: 10/28, Ad/Sq/AdSq/Un: 17/17/2/2. The response rate of this chemoradiotherapy was 78.9%. The median survival time and time to progression were 24.7 months and 8.1 months, respectively. Grade 3 or 4 hematological toxicities during concomitant chemoradiotherapy were leukocytopenia (5.2%) and neutropenia (5.2%). Grade 3 or 4 non-hematological toxicities were esophagitis (2.6%) and pneumonitis (5.2%). There was a therapy-associated death by radiation pneumonitis. Carboplatin and paclitaxel with concurrent radiation therapy for a patient with stage III NSCLC showed a good response with relatively mild side effects. We reached the conclusion that concurrent chemoradiotherapy would be a useful choice for locally advanced non-small cell lung cancer on the practical clinic. (author)

  6. Treatment Recommendations for Locally Advanced, Non-Small-Cell Lung Cancer: The Influence of Physician and Patient Factors

    International Nuclear Information System (INIS)

    Purpose: To determine the impact of patient age, comorbidity, and physician factors on treatment recommendations for locally advanced, unresectable non-small-cell lung cancer (NSCLC). Methods and Materials: We surveyed radiation oncologists regarding their recommendations for treatment (chemoradiation, radiation alone, chemotherapy alone, or no therapy) for hypothetical patients with Stage IIIB NSCLC who varied by age (55 vs. 80 years) and comorbid illness (none, moderate, or severe chronic obstructive pulmonary disease [COPD]). Multinomial logistic regression was used to assess the impact of physician and practice characteristics on radiation oncologists' treatment recommendations for three scenarios with the least agreement. Results: Of 214 radiation oncologists, nearly all (99%) recommended chemoradiation for a healthy 55 year old. However, there was substantial variability in recommendations for a 55 year old with severe COPD, an 80-year-old with moderate COPD, and an 80-year-old with severe COPD. Physicians seeing a lower volume of lung cancer patients were statistically less likely to recommend radiotherapy for younger or older patients with severe COPD (both p < 0.05), but the impact was modest. Conclusions: Nearly all radiation oncologists report following the evidence-based recommendation of chemoradiation for young, otherwise healthy patients with locally advanced, unresectable NSCLC, but there is substantial variability in treatment recommendations for older or sicker patients, probably related to the lack of clinical trial data for such patients. The physician and practice characteristics we examined only weakly affected treatment recommendations. Additional clinical trial data are necessary to guide recommendations for treatment of elderly patients and patients with poor pulmonary function to optimize their management.

    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.

  11. 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

    Lung cancer is the leading cause of cancer mortality worldwide. Non-small cell lung cancer (NSCLC), accounting for about 85% of all lung cancers, includes squamous carcinoma, adenocarcinoma and undifferentiated large cell carcinoma. The majority of patients have advanced disease at diagnosis, and medical treatment is the cornerstone of management. Several randomized trials comparing third-generation platinum-based doublets concluded that all such combinations are comparable in their clinical efficacy, failing to document a difference based on histology. However, recent evidences, arising from the availability of pemetrexed, have shown that histology represents an important variable in the decision making. The major progresses in the understanding cancer biology and mechanism of oncogenesis have allowed the development of several potential molecular targets for cancer treatment such as vascular growth factor and its receptors and epidermal growth factor receptor. Targeted drugs seem to be safer or more effective in a specific histology subtype. All of these data have led to choose the optimal first-line treatment of advanced NSCLC based on histologic diagnosis. However, this scenario raises a diagnostic issue: a specific diagnosis of NSCLC histologic subtype is mandatory. This review will discuss these new evidences in the first-line treatment of advanced NSCLC and their implication in the current clinical decision-making. PMID:20156162

  15. Outcome of 289 locally advanced non-small cell lung cancer treated with radiotherapy alone and radiotherapy combined with chemotherapy

    International Nuclear Information System (INIS)

    Objective: To retrospectively analyze the outcome of locally advanced non-small cell lung cancer patients treated with radiotherapy and chemoradiotherapy. Methods: 289 patients who were treated either by radiotherapy alone (168 patients) or radiotherapy plus chemotherapy (121 patients) from Dec. 1999 to Dec. 2002 were entered into the database for analysis. Pathological types: squamous cancer (152), adenocarcinoma(74), squamoadenocarcinoma(2) and other types (2). 24 showed cancer unclassificable and 35 were diagnosed without pathological proof. 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%).

    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.

  18. Microwave Ablation in Combination with Chemotherapy for the Treatment of Advanced Non-Small Cell Lung Cancer

    International Nuclear Information System (INIS)

    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

    Accurate tumor staging is essential for choosing the appropriate treatment strategy inpatients with lung cancer. It has already been shown that FDG-PET is highly accurate inclassifying lung nodules as benign or malignant. Integrated PET-CT enables the exactmatching of focal abnormalities on PET to anatomic structures on CT. PET-CT is superior indiagnostic accuracy for T staging and differentiation between tumor and peritumoral atelectasis.PET has also proved to be a very effective staging mod...

    Full Text Available Background and objective NKG2D-expressing NK cells and soluble major histocompatibility complex class Ⅰ-related chain A (sMICA is one of aroused general interests in tumor research area recently. The aimof the study is to investigate the levels of NKG2D-expressing NK cells and sMICA in peripheral blood of advanced lung cancer which are remarkably related to clinical significance and analyse the role of NKG2D-expressing NK cells and sMICA in immune surveillance. Methods Flow cytometry was used to determine the percentage of NKG2D-expressing NK cells, T cell subsets, NK cells, and ELISA was used to mesure the levels of sMICA in peripheral blood of 115 advanced lung cancer patients and 50 healthy controls. Results Compared with control group, the levels of sMICA、CD8+T cells, NK cells increased, while the levels of NKG2D-expressing NK cells, CD3+ T cells, CD4+ T cells, CD4+ T/CD8+ T in experimental group decreased. NKG2D-expressing NK cells had a perfect negative correlation with sMICA (r =-0.319, P <0.05. NKG2D-expressing NK cells had positive correlation with CD4+ T cells, CD4+ T/CD8+ T and negative correlationwith CD8+ T cells (P <0.05, sMICA had negative correlation with CD4+ T cells, CD4+ T/CD8+ T and positive correlation with CD8+ T cells (P <0.05, they had no significant correlation with CD3+ T cells, NK cells respectively (P <0.05. Conclusion Accumulation of sMICA in serum may lead to the down-modulation of NKG2D-expressing NK which has been proposed to be a novel mechanism used by cancer cells to evade the tumor immunosurveillance. They may be potential indicators investigating immune functions and helpful in the evaluation of their happening and proceeding.

    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.

    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.

  6. Therapeutic effects of gensenoside-Rg3 combined with radiotherapy on advanced non-small cell lung cancer

    International Nuclear Information System (INIS)

    Objective: To study the efficacy and toxicity of gensenoside-Rg3 (Rg3) combined with radiotherapy on non-small cell lung cancer (NSCLC) at advanced stages (Ⅲ and Ⅴ). Methods: Sixty-three patients with stage Ⅲ or Ⅳ NSCLC were divided randomly into two groups:treatment group (n=35) treated with Rg3 combined with radiotherapy and control group (n=28) treated with radiotherapy alone. The efficacy and side effects were compared after the treatment. Results: The response rate (CR + PR) of the treatment group was 57.14%, significantly higher than that of the control group (32.14%, χ2 =3.91, P<0.05). The median survival time of the treatment group was 14.2 months, significantly longer than that of the control group (11.2 months, χ2=2.07, P<0.05). The one-year survival rate of the treatment group was 62.86%, significantly higher than that of the control group (39.29%, χ2=4.40, P<0.05). The incidence rates of side effects of the treatment group were all lower than those of the control group, but there were not significant difference. Conclusions: Gensenoside-Rg3 combined with radiotherapy is effective for advanced stage NSCLC, with attenuation and synergistic effects. (authors)

  7. Risk factors associated with fatal pulmonary hemorrhage in locally advanced non-small cell lung cancer treated with chemoradiotherapy

    International Nuclear Information System (INIS)

    The purpose of this study was to identify the risk factors associated with fatal pulmonary hemorrhage (PH) in patients with locally advanced non-small cell lung cancer (NSCLC), treated with chemoradiotherapy. The medical records of 583 patients with locally advanced NSCLC, who were treated with chemoradiotherapy between July 1992 and December 2009 were reviewed. Fatal PH was defined as PH leading to death within 24 h of its onset. Tumor cavitation size was defined by the cavitation diameter/tumor diameter ratio and was classified as minimum (< 0.25), minor (≥ 0.25, but < 0.5), and major (≥ 0.5). Of the 583 patients, 2.1% suffered a fatal PH. The numbers of patients with minimum, minor, and major cavitations were 13, 11, and 14, respectively. Among the 38 patients with tumor cavitation, all 3 patients who developed fatal PH had major cavitations. On multivariate analysis, the presence of baseline major cavitation (odds ratio, 17.878), and a squamous cell histology (odds ratio, 5.491) proved to be independent significant risk factors for fatal PH. Interestingly, all patients with fatal PH and baseline major cavitation were found to have tumors with squamous cell histology, and the occurrence of fatal PH in patients having both risk factors was 33.3%. Patients at high risk of fatal PH could be identified using a combination of independent risk factors

    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.

    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.

    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. PMID:27279143

    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

The purpose of this article was to review the economics of first-line and maintenance NSCLC treatments. We reviewed economic analyses of NSCLC therapies published between 2004 and 2014. In first-line settings, in unselected patients with advanced NSCLC, the cisplatin gemcitabine doublet appears to be cost-saving compared with other platinum doublets. In patients with nonsquamous NSCLC, the incremental cost-effectiveness ratios (ICERs per life-year gained (LYG were $83,537, $178,613, and more than $300,000 for cisplatin-pemetrexed compared with, respectively, cisplatin-gemcitabine, cisplatin-carboplatin-paclitaxel, and carboplatin-paclitaxel-bevacizumab. For all primary chemotherapy agents, use of carboplatin is associated with slightly higher costs than cisplatin. In all the analysis, bevacizumab had an ICER greater than $150,000 per quality-adjusted life-year (QALY. In epidermal growth factor receptor mutated advanced NSCLC, compared with carboplatin-paclitaxel doublet, targeted therapy based on testing available tissue yielded an ICER of $110,644 per QALY, and the rebiopsy strategy yielded an ICER of $122,219 per QALY. Compared with the triplet carboplatin-paclitaxel-bevacizumab, testing and rebiopsy strategies had ICERs of $25,547 and $44,036 per QALY

  18. Combining advanced radiotherapy technologies to maximize safety and tumor control probability in stage III non-small cell lung cancer

    International Nuclear Information System (INIS)

    Background: The goal of the current study was to investigate the tumor control probability (TCP) of advanced radiotherapy technologies for stage III non-small cell lung cancer (NSCLC) and to evaluate potential interplay effects between their applications. Materials and methods: Three-dimensional conformal radiotherapy (3D-CRT) with conventionally fractionated doses of 66 Gy served as reference for 13 patients with stage III NSCLC. Isotoxic dose escalation relative to the corresponding 3D-CRT plans was performed for three technologies and their combinations: intensity-modulated radiotherapy (IMRT), IMRT with a simultaneous integrated boost (IMRT-SIB) of 10% to the gross tumor volume (GTV), and adaptive re-planning twice during the treatment course (ART). All analyses were based on accumulated dose distributions using deformable image registration of CT images, which were acquired weekly during the treatment course. Results: IMRT reduced the mean lung dose (MLD) by 5.6% ± 3.8% compared to 3D-CRT. ART resulted in lung sparing of 7.9% ± 4.8% and 9.2% ± 3.9% in 3D-CRT and IMRT planning, respectively. IMRT and ART escalated the irradiation dose by 6.6% ± 3.2% and 8.8% ± 6.3%, respectively, which was not statistically different. For the 7 patients with the largest GTVs, IMRT-SIB was superior to IMRT and ART with dose escalation of 11.9% ± 3.7%. The combination of ART, IMRT, and SIB achieved maximum dose escalation in all 13 patients by 17.1% ± 5.4% on average, which increased TCP from 19.9% ± 7.0 to 37.1% ± 10.1%. Adaptive re-planning was required to continuously conform the escalated and hypofractionated SIB doses to the shrinking tumor. Conclusion: Combining advanced radiotherapy technologies is considered as a safe and effective strategy to maximize local tumor control probability in stage III NSCLC. (orig.)

    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 ∼ 64.8 (median 64.8) Gy (daily 1.8 Gy per fraction, 5 days per weeks) over 7 ∼ 8 weeks. 50 or 60 mg/m2 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/m2 and cisplatin 75 mg/m2 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.

    Staging classification in patients with non-small cell lung cancer does not always correlate perfectly with surgical resectability. Therefore, it is important to evaluate individual features of a patient’s tumor in order to determine if surgical resection is the optimal method of treatment, regardless of tumor stage. Such features include characteristics of the primary tumor, regional lymph nodes and distant sites.

  2. 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

    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

    Small-cell lung cancer (SCLC) comprises approximately 14% of all lung cancer cases. Most patients present with locally advanced or metastatic disease and are therefore treated nonoperatively with chemotherapy, radiotherapy, or both. A small subset of patients with SCLC present with early-stage disease and will benefit from surgical resection plus chemotherapy. The rationale for radiotherapy in these patients remains controversial. PMID:25441133

  8. 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

    Full Text Available Objective: The aim of this study was to evaluate elevated platelet count as a prognostic factor for survival in patients with advanced (stage IIIB/ IV non- small cell lung cancer (NSCLC receiving first- line chemotherapy. Methods: From 2005 to 2009 three hundreds forty seven consecutive patients with stage IIIB or IV NSCLC, treated in Department of Medical Oncology, UMHAT "Dr Georgi Stranski" entered the study. The therapeutic regimens included intravenous administration of platinum- based doublets. Survival analysis was evaluated by Kaplan- Meier test. The influence of pretreatment thrombocytosis as prognostic factor for survival was analyzed using multivariate stepwise Cox regression analyses. Results: Elevated platelet counts were found in 78 patients. The overall survival for patients without elevated platelet counts was 9,6 months versus 6,9 months for these with thrombocytosis. In multivariate analysis as independent poor prognostic factors were identified: stage, performance status and elevated platelet counts. Conclusions: These results indicated that platelet counts as well as some clinical pathologic characteristics could be useful prognostic factors in patients with unresectable NSCLC.

    Non-small cell lung cancers (NSCLC) have unique mutation patterns, and some of these mutations may be used to predict prognosis or guide patient treatment. Mutation profiling before and during treatment often requires repeated tumor biopsies, which is not always possible. Recently, cell-free, circulating tumor DNA (ctDNA) isolated from blood plasma has been shown to contain genetic mutations representative of those found in the primary tumor tissue DNA (tDNA), and these samples can readily be obtained using non-invasive techniques. However, there are still no standardized methods to identify mutations in ctDNA. In the current study, we used a targeted sequencing approach with a semi-conductor based next-generation sequencing (NGS) platform to identify gene mutations in matched tDNA and ctDNA samples from 42 advanced-stage NSCLC patients from China. We identified driver mutations in matched tDNA and ctDNA in EGFR, KRAS, PIK3CA, and TP53, with an overall concordance of 76%. In conclusion, targeted sequencing of plasma ctDNA may be a feasible option for clinical monitoring of NSCLC in the near future. PMID:26582655

    2012-08-01

    Purpose: To assess the clinical impact of the Acuros XB algorithm (implemented in the Varian Eclipse treatment-planning system) in non-small-cell lung cancer (NSCLC) cases. Methods and Materials: A CT dataset of 10 patients presenting with advanced NSCLC was selected and contoured for planning target volume, lungs, heart, and spinal cord. Plans were created for 6-MV and 15-MV beams using three-dimensional conformal therapy, intensity-modulated therapy, and volumetric modulated arc therapy with RapidArc. Calculations were performed with Acuros XB and the Anisotropic Analytical Algorithm. To distinguish between differences coming from the different heterogeneity management and those coming from the algorithm and its implementation, all the plans were recalculated assigning Hounsfield Unit (HU) = 0 (Water) to the CT dataset. Results: Differences in dose distributions between the two algorithms calculated in Water were <0.5%. This suggests that the differences in the real CT dataset can be ascribed mainly to the different heterogeneity management, which is proven to be more accurate in the Acuros XB calculations. The planning target dose difference was stratified between the target in soft tissue, where the mean dose was found to be lower for Acuros XB, with a range of 0.4% {+-} 0.6% (intensity-modulated therapy, 6 MV) to 1.7% {+-} 0.2% (three-dimensional conformal therapy, 6 MV), and the target in lung tissue, where the mean dose was higher for 6 MV (from 0.2% {+-} 0.2% to 1.2% {+-} 0.5%) and lower for 15 MV (from 0.5% {+-} 0.5% to 2.0% {+-} 0.9%). Mean doses to organs at risk presented differences up to 3% of the mean structure dose in the worst case. No particular or systematic differences were found related to the various modalities. Calculation time ratios between calculation time for Acuros XB and the Anisotropic Analytical Algorithm were 7 for three-dimensional conformal therapy, 5 for intensity-modulated therapy, and 0.2 for volumetric modulated arc therapy

    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.

    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)

  11. 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.

    Background Matrix metalloproteinase 9 (MMP-9) plays an important role in tumor invasion and metastasis, including lung cancer. However, whether variations in serum MMP-9 levels can serve as a biomarker for monitoring chemotherapy curative effect remains unclear. This study was designed to investigate the association between variations in serum MMP-9 levels and chemotherapy curative effect in patients with lung cancer. Patients and methods A total of 82 patients with advanced lung cancer were included. All newly diagnosed patients were treated with platinum-based doublet chemotherapy. Serial measurements of serum MMP-9 levels were performed by enzyme-linked immunosorbent assay. In this manner, we chose four time points to examine the association, including before chemotherapy, and 3 weeks after the beginning of the first, second, and fourth cycles of chemotherapy. Results Compared with the serum level of MMP-9 before progressive disease, patients with progressive disease had elevated serum levels of MMP-9. Compared with the previous time point of collecting specimens, the serum levels of MMP-9 in the patients with a complete response/partial response/stable disease decreased or were maintained stable. The differences of variation in serum MMP-9 levels in patients with different chemotherapy curative effects were all statistically significant after one cycle, two cycles, and four cycles (after one cycle: P<0.001; after two cycles: P<0.001; after four cycles: P=0.01). However, patients with small-cell lung cancer did not exhibit similar test results. Conclusion The variation in serum MMP-9 levels in patients with non-small-cell lung cancer during chemotherapy was closely related to chemotherapy curative effect and could be useful to monitor chemotherapy curative effect for a small portion of patients.

    Smoking tobacco, both cigarettes and beedis, is the principal risk factor for causation of lung cancer in Indian men; however, among Indian women, the association with smoking is not strong, suggesting that there could be other risk factors besides smoking. Despite numerous advances in recent years in terms of diagnostic methods, molecular changes, and therapeutic interventions, the outcomes of the lung cancer patients remain poor; hence, a better understanding of the risk factors may impact the preventive measures to be implemented at the community level. There is a lack of comprehensive data on lung cancer in India. In this review, we attempt to collate the available data on lung cancer from India. PMID:27606290

    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 Surgery remains the best curative option in patients with early stage lung cancer (stage I and II. Developments in minimally invasive techniques now allow surgeons to perform lung resections on elderly patients, patients with poor pulmonary function or significant cardiopulmonary comorbidities. New techniques, such as stereotactic radiotherapy and ablative procedures, are being evaluated in early-stage lung cancer and may represent an alternative to surgery in patients unfit for lung resection. Perioperative mortality rates have dropped significantly at most institutions in the past two decades and complications are managed more efficiently. Progress in imaging and staging techniques have helped cut futile thoracotomy rates and offer patients the most adequate treatment options. Large randomised trials have helped clarify the role of neoadjuvant, induction and adjuvant chemotherapy, as well as radiotherapy. Surgery remains an essential step in the multimodality therapy of selected patients with advanced-stage lung cancer (stage III and IV. Interventional and endoscopic techniques have reduced the role of surgery in the diagnosis and staging of nonsmall cell lung cancer, but surgery remains an important tool in the palliation of advanced-stage lung cancer. Large national/international surgical databases have been developed and predictive risk-models for surgical mortality/morbidity published by learned surgical societies. Nonetheless, lung cancer overall survival rates remain deceptively low and it is hoped that early detection/screening, better understanding of tumour biology and development of biomarkers, and development of efficient targeted therapies will help improve the prognosis of lung cancer patients in the next decade.

    Objective: To evaluate the clinical efficacy of 125I particles implantation in the treatment of tracheal stenosis due to advanced lung cancer. Methods: Eighteen cases with end stage lung cancer were collected.125I particles were implanted by inserting the bronchoscope into the pathological bronchial tubes of distal puncture. The number of 125I particles implanted ranged from 4-15. The tumor sizes were compared before and 30 d, 60 d, 180 d after the 125I particles implantation according to the examination of CT, and the clinical symptoms were studied. Results: The symptoms of shortness of breath were relieved after 125I particles implantation. Thirty days follow-up after the therapy showed 15 cases of enlarged bronchial lumen, 13 cases of disappeared obstructive pneumonia symptoms, and no obvious complication occurred during the follow-up. Conclusion: The implantation of 125I radioactive particles has a good effect for the tracheal stenosis in the treatment of advanced lung cancer; the therapy is safe and worth to be spread. (authors)

  1. Dynamic contrast-enhanced CT in advanced lung cancer after chemotherapy with/within radiation therapy: Can it predict treatment responsiveness of the tumor?

    International Nuclear Information System (INIS)

    To evaluate the contrast enhancement patterns of lung cancer after chemotherapy using a dynamic contrast-enhanced (DCE) CT and to determine whether the enhancement patterns of tumors at early stages of treatment can predict treatment responses. Forty-two patients with advanced lung cancers underwent DCE-CT and follow-up CT after chemotherapy. We evaluated peak and net enhancement (PE and NE, respectively) and time-density curves (TDCs) (type A, B, C, and D) on DCE-CT images. Treatment responses were evaluated using revised Response Evaluation Criteria in Solid Tumor criteria. NE and PE values were significantly higher in the progressive disease (PD) groups than in the stable disease (SD) or partial response (PR) groups (p < 0.05). Types B, C, and D on TDCs were observed mostly in the PR and SD groups (96.0%), whereas type A was most frequent in the SD and PD groups (97.2%), which were significantly different in terms of PE and NE. Contrast enhancement pattern regarding the response of treatment on DCE-CT images could be helpful in predicting treatment response of advanced lung cancer after treatment.

    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

  3. 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

    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.

    To evaluate the predictive value of the early response of 18F-flurodeoxyglucose positron emission tomography (FDG PET) during concurrent chemoradiotherapy (CCRT) for locally advanced non-small cell lung cancer (NSCLC). FDG PET was performed before and during CCRT for 13 NSCLC patients. Maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) were measured and the changes were calculated. These early metabolic changes were compared with the standard tumor response by computed tomograms (CT) one month after CCRT.One month after the completion of CCRT, 9 patients had partial response (PR) of tumor and 4 patients had stable disease. The percent changes of SUVmax (%DeltaSUVmax) were larger in responder group than in non-responder group (55.7% +/- 15.6% vs. 23.1% +/- 19.0%, p = 0.01). The percent changes of SUVmean (%DeltaSUVmean) were also larger in responder group than in non-responder group (54.4% +/- 15.9% vs. 22.3% +/- 23.0%, p = 0.01). The percent changes of MTV (%DeltaMTV) or TLG (%DeltaTLG) had no correlation with the tumor response after treatment. All the 7 patients (100%) with %DeltaSUVmax > or = 50% had PR, but only 2 out of 6 patients (33%) with %DeltaSUVmax < 50% had PR after CCRT (p = 0.009). Likewise, all the 6 patients (100%) with %DeltaSUVmean > or = 50% had PR, but only 3 out of 7 patients (43%) with %DeltaSUVmean < 50% had PR after CCRT (p = 0.026). The degree of metabolic changes measured by PET-CT during CCRT was predictive for NSCLC tumor response after CCRT.

  6. Response to combined modality therapy correlates with survival in locally advanced non-small-cell lung cancer

    International Nuclear Information System (INIS)

    Purpose: Although concurrent chemoradiotherapy can now achieve demonstrated long-term survival in patients with locally advanced non-small-cell lung cancer (LANSCLC), it is difficult to predict which patients will benefit most from this therapeutic approach. Studies have suggested that local control, and the response to therapy, may be linked to improved survival; however, detailed analysis of the impact of tumor response to chemoradiotherapy on survival has not been thoroughly reported. Therefore, we sought to determine the impact of the response rate on survival for patients who were treated with combined modality therapy for LANSCLC. Methods and Materials: We reviewed the data from 116 patients enrolled between 1994 and 1997 in three trials investigating paclitaxel-based concurrent chemoradiotherapy for LANSCLC. Tumor size measurements were assessed immediately before and 2 months after completion of combined modality therapy to determine the response and to calculate the percentage of decrease in tumor size. Results: Patients with a response (complete or partial) had an improved 4-year overall survival rate compared with patients with no response (stable or progressive disease; 21.1% vs. 3.3%, p <0.0001) in the 109 assessable patients. Progression-free survival also improved significantly with response. An analysis of the percentage of decrease in tumor size vs. survival was performed (n = 74) using Cox proportion model analysis. After combined modality therapy, a 20%, 40%, 60%, 80%, and 100% decrease in tumor size conferred a 39%, 63%, 78%, 86%, and 92% reduction in risk of death compared with a 0% decrease in tumor size (p <0.0001). Conclusion: The response by conventional response criteria correlated strongly with improved overall survival and progression-free survival and an increasing percentage of decrease in tumor size resulted in a reduction in the risk of death. Additional investigation of the degree of response as a factor predictive of improved

  7. FDG PET for staging of advanced non-small cell lung cancer prior to neoadjuvant radio-chemotherapy

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate positron emission tomography (PET) with fluorine-18 fluorodeoxyglucose (FDG) for the staging of non-small cell lung cancer (NSCLC) before combined neoadjuvant, i.e. preoperative, radio-chemotherapy (RCT). From November 1998 until September 2001, 101 patients with NSCLC were investigated prospectively. The inclusion criterion was a histologically proven NSCLC of stage IIIA or B according to conventional staging including biopsy. The results of PET were compared with those obtained by mediastinoscopy, computed tomography (CT), bone scan and abdominal ultrasonography. Validation of discrepant findings was achieved by biopsy or repeated CT. PET proved to be highly accurate for the detection of lymph node metastases (sensitivity 96%, specificity 73%, positive predictive value 88%, negative predictive value 89%, accuracy 88%) as well as distant metastases (in 25/101 patients, all previously unknown). PET findings changed further treatment in 29/101 patients (29%). Twenty-five were excluded from RCT due to the presence of previously unknown distant metastases. One patient was free of metastases and therefore was operated on without pre-treatment. Two patients did not receive any further treatment because a malignant tumour could be excluded after PET. In the final patient PET demonstrated a tumour pattern not typical for NSCLC which could be attributed to a seminoma after repeated biopsy. FDG PET is the most accurate non-invasive diagnostic procedure for the staging of advanced NSCLC. Therefore use of FDG PET is highly recommended in order to select patients for neoadjuvant or other stage-dependent treatment modalities. (orig.)

    2016-05-01

    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

    The tyrosine kinase inhibitors (TKI) against epidermal growth factor receptor (EGFR) are widely used in patients with non-small cell lung cancer (NSCLC). However, EGFR T790M mutation leads to resistance to most clinically available EGFR TKIs. Third-generation EGFR TKIs against the T790M mutation have been in active clinical development. These agents include osimertinib, rociletinib, HM61713, ASP8273, EGF816, and PF-06747775. Osimertinib and rociletinib have shown clinical efficacy in phase I/...

    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.

    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.

  14. Concurrent Chemoradiotherapy with Biweekly Gemcitabine and Cisplatin in Patients with Locally Advanced Non-small Cell Lung Cancer

    International Nuclear Information System (INIS)

    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

    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.

    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

    The activation of lymphocytes by gefitinib treatment has been described. In this phase II pilot trial, we explored the possible synergism between IL-2 and gefitinib for non-small cell lung cancer (NSCLC) treatment. From September, 2003, to November, 2006, 70 consecutive patients with advanced, progressive NSCLC, previously treated with chemotherapy, received oral gefitinib 250 mg daily. The first 39 patients received gefitinib alone (G group). The other 31 also received subcutaneous IL-2 (GIL-2 group): 1 MIU/m{sup 2} (Million International Unit/m{sup 2})twice a day on Days 1 and 2, once a day on Days 3, 4, 5 every week for four consecutive weeks with a four-week rest period. Median follow-up was 25.2 months. Grade 3–4 toxicity of gefitinib was represented by skin rash (7%), asthenia/anorexia (6%) and diarrhea (7%); patients treated with IL-2 showed grade 2–3 fever (46%), fatigue (21%) and arthralgia (13%). In the GIL-2 group and G-group, we respectively observed: an overall response rate of 16.1% (6.4% complete response) and 5.1% (only partial response); a disease control rate of 41.9% and 41%; a median time to progression of 3.5 (CI 95% = 3.2–3.8) and 4.1 (CI 95% = 2.6–5.7) months; a median overall survival of 20.1 (CI 95% = 5.1–35.1) and 6.9 (CI 95% = 4.9–8.9) months (p = 0.002); and an actuarial one-year survival rate of 54% and 30%. Skin toxicity (p < 0.001; HR = 0.29; CI 95% = 0.16–0.54) and use of IL-2 (p < 0.001; HR = 0.33; CI 95% = 0.18–0.60) were independently associated with improvement of survival. In this consecutive, non-randomized, series of advanced NSCLC patients, the use of IL-2 increased the efficacy of gefitinib.

    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.)

    Grade {>=}3 radiation pneumonitis (RP) is generally severe and life-threatening. Predictors of grade {>=}2 are usually used for grade {>=}3 RP prediction, but it is unclear whether these predictors are appropriate. In this study, predictors of grade {>=}2 and grade {>=}3 RP were investigated separately. The increased risk of severe RP in elderly patients compared with younger patients was also evaluated. Material and methods: A total of 176 consecutive patients with locally advanced non-small cell lung cancer were followed up prospectively after three-dimensional conformal radiotherapy. RP was graded according to Common Terminology Criteria for Adverse Events version 3.0. Results: Mean lung dose (MLD), mean heart dose, ratio of planning target volume to total lung volume (PTV/Lung), and dose-volume histogram comprehensive value of both heart and lung were associated with both grade {>=}2 and grade {>=}3 RP in univariate analysis. In multivariate logistic regression analysis, age and MLD were predictors of both grade {>=}2 RP and grade {>=}3 RP; receipt of chemotherapy predicted grade {>=}3 RP only; and sex and PTV/Lung predicted grade {>=}2 RP only. Among patients who developed high-grade RP, MLD and PTV/Lung were significantly lower in patients aged {>=}70 years than in younger patients (p<0.05 for both comparisons). Conclusions: The predictors were not completely consistent between grade {>=}2 RP and grade {>=}3 RP. Elderly patients had a higher risk of severe RP than younger patients did, possibly due to lower tolerance of radiation to the lung.

    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

    Lung cancer is a global health burden and is among the most common and deadliest of all malignancies worldwide. The goal of screening programs is to detect tumors in earlier, curable stages, consequently reducing disease-specific mortality. The issue of screening has great relevance to thoracic surgeons, who should play a leading role in the debate over screening and its consequences. The burden is on thoracic surgeons to work in a multidisciplinary setting to guide and treat these patients safely and responsibly, ensuring low morbidity and mortality of potential diagnostic or therapeutic interventions.

    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. As CSC plays an critical role in tumor recur-rence, metastasis and drug-resistance, understanding the difference between lung CSCs and normal lung SCs, identifying and targeting

    近年来成体干细胞研究进展迅速.肺干细胞和肺癌干细胞在表面标志、分离方法和功能研究等方面也取得了一定进展.在肺组织中,肺干细胞维持着肺上皮的更新和稳定,肺脏不同解剖结构存在不同的干细胞,主要的肺干细胞有气管-支气管干细胞、细支气管干细胞、细支气管肺泡干细胞和肺泡干细胞等,不同干细胞特异表面标志也不同.根据肿瘤干细胞理论,目前研究认为肺癌的发生与肺癌干细胞有关,肺癌干细胞来源于其对应肺干细胞的恶性转化.肺癌干细胞特异标志研究主要集中在侧群细胞、CD133和醛脱氢酶等.与其他成体干细胞相似,肺癌干细胞维持自我更新以及分化能力的信号通路主要有Wnt、Hedgehog和Notch通路等.肺癌干细胞与肺癌的发生、发展、转移、治疗反应及预后关系,也取得了一定的进展.该文对肺干细胞和肺癌干细胞研究进展作简要综述.%Lung stem cells were very important for the lung epithelium renewal and stabilization. Currently, studies suggest that there were four kinds of lung stem cells in different anatomical site. According to the tumor stem cell theory, the lung cancer was related to the lung cancer stem cell and the lung stem cell. The surface markers and the signaling pathway, which maintain the self-renewal and differentiation, are similar to the other stem cells. 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.

    Epidemiologic studies over the last 40 years suggest rather consistently that general ambient air pollution, chiefly due to the incomplete combustion of fossil fuels, may be responsible for increased rates of lung cancer. This evidence derives from studies of lung cancer trends, studies of occupational groups, comparisons of urban and rural populations, and case-control and cohort studies using diverse exposure metrics. Recent prospective cohort studies observed 30 to 50% increases in lung ca...

  12. 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)

  14. Status of particle therapy for lung cancer

    International Nuclear Information System (INIS)

    The current standard treatment for lung cancer, the most common type of cancer worldwide, depends on disease stage. Surgery is the treatment of choice for early-stage tumors, but radiotherapy is a good option for those with early-stage tumors who cannot undergo surgery, and radiotherapy in conjunction with chemotherapy is the standard of care for locally advanced tumors. Although advances in photon (x-ray)-based radiotherapy involving three-dimensional conformal radiotherapy and intensity-modulated radiotherapy allow radiation doses to be escalated beyond the traditional limit of 60 Gy, this dose is not considered to be sufficient for tumor eradication. Moreover, the improvements in local control and survival conferred by concurrent chemotherapy come at the cost of considerable toxicity owing to inadvertent irradiation of surrounding normal tissues, and this toxicity often limits the radiation dose that can be delivered. Unfortunately for patients with locally advanced lung cancer, local control and survival remain poor. Attempts to improve clinical outcomes for patients with lung cancer have led to the use of charged particle therapy in an effort to exploit the physical properties of such particles to escalate the dose to the tumor while simultaneously limiting the dose to nearby structures, thereby enhancing the therapeutic ratio and potentially improving cancer cure rates. This review summarizes the rationale for and challenges associated with the use of charged particles for lung cancer therapy and reviews the clinical experience to date with using protons and carbon ions for early-stage and locally advanced stage non-small cell lung cancer

    Full Text Available Context: There are limited effective therapeutic options in the relapsed setting for non-small cell lung cancer (NSCLC or in the first line for platinum-ineligible patients. Aim: To evaluate the safety and efficacy of a metronomic schedule of paclitaxel administered weekly in relapsed refractory NSCLC or upfront in patients not eligible for platinum-based chemotherapy. Settings and Design: Retrospective analysis of a prospectively collected database from the medical oncology department at Tata Memorial Hospital in Mumbai, India. Materials and Methods: Patients with recurrent and treatment-naïve platinum-ineligible advanced NSCLC were treated with weekly paclitaxel at 80 mg/m 2 with palliative intent. Restaging scans were obtained every two months. Chemotherapy was continued until progressive disease, intolerable side effects, or decision of the patient. Statistical Analysis Used: SPSS version 16 was used for analysis. Simple percentages were used for descriptive statistics. Progression-free survival (PFS was calculated from date of start of paclitaxel till the date of progression, change of therapy due to any reason, or death due to any cause. Overall survival (OS was calculated from date of start of paclitaxel to death. The Kaplan Meier method was used for estimation of survival. Results: There were 37 patients over eight months. The median age was 59 years, with a male-to-female ratio of 5:1. Two patients received paclitaxel in the first line, 18 patients in second line, nine in third line, five in fourth line, and three were in fifth line. 73% patients had received prior platinum and 48.6% patients had Eastern Cooperative Oncology Group performance status (ECOG PS >2. The median number of weekly cycles delivered was 14. The response rate was 35% [complete remission (CR: 2.7%, partial remission (PR: 32.4%, stable disease (SD: 32.4%, progressive disease (PD: 27%], the median PFS was four months, and the estimated median OS was seven months

  16. Risk Factors for Brain Metastases in Locally Advanced Non-Small Cell Lung Cancer With Definitive Chest Radiation

    International Nuclear Information System (INIS)

    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

    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 ...

    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.

    Full Text Available Background and objective Since the poor outcome for advanced lung cancer with first-line chemotherapy, more efforts should be paid for treatment of advanced recurrent or metastasis non-small cell lung cancer (NSCLC patients. Pemetrexed, as a multi-target antifolate chemotherapeutic drug, was approved for the second-line treatment of advanced NSCLC. The aim of this study is to evaluate the efficacy and side effects of pemetrexed combined with cisplatin/carboplatin in the treatment of advanced recurrent or metastasis NSCLC. Methods Sixty-three advanced recurrent or metastasis NSCLC patients confirmed with pathology or cytology were enrolled in this study. Among them, 40 cases were male and 23 were female, with 62 years of median age. The combination regimen was patients received pemetrexed 500 mg/m2 on day 1 and cisplatin 30 mg/m2 on day 1, day 2 and day 3 or carboplatin 300 mg/m2 on day 1 by intravenous infusion, with 21 days as one cycle. All patients who received 2 or more cycles could be evaluated. Results Only 1 case got complete response, with 5 cases partial response, 36 stable and 21 cases progressive. The overal control rate was 66.7% (42/63. The median survival time was 9.0 months, while the median progression-free survival was 5.0 months (3.0 months in squamous cell carcinoma; 5.5 months in adenocarcinoma. There was a significant difference between squamous cell carcinoma and adenocarcinoma (P=0.017. The common adverse effects were leucopenia, anemia and gastrointestinal response. Conclusion Pemetrexed combined with cisplatin/carboplatin is effective and feasible for advanced recurrent or metastasis NSCLC.

    Lung cancer remains the leading cause of death in the United States. Although the incidence of cigarette smoking is decreasing in the United States it appears to be increasing worldwide. The five-year survival rate has not improved in cases with advanced disease, but several articles have indicated that survival can be improved in cases diagnosed early by sputum cytology and chest x-ray. In cases diagnosed while the lesion is in the in-situ stage or measures less than 1 cm in diameter, surgical excision and/or radiation therapy improves survival; therefore, the early diagnosis of high-risk patients should be vigorously pursued. A recent study at a community hospital in Grand Junction, Colorado, presented 45 lung cancer cases diagnosed with positive sputum cytology and negative chest x-ray, and indicates that early diagnosis does improve survival. This study has been conducted during the past six years; 16 cases have survived three years and six cases show five-year survival.

    2016-02-01

    After decades of setbacks, cancer immunology is living its Golden Age. Recent advances in cancer immunology have provided new therapeutic approaches to treat cancer. The objective clinical response observed in patients treated with antibodies that block the immune checkpoints, cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell-death protein 1 (PD-1)/programmed cell-death 1 ligand 1 (PD-L1) pathways, has led to their FDA approval for the treatment of melanoma in 2011 and in 2014, respectively. The anti-PD-1 antibody nivolumab has received the FDA-approval in March 2015 for squamous lung cancer treatment. In addition, antibodies targeting PD-1 or PD-L1 have demonstrated their efficacy and safety in additional tumors, including non-small cell lung carcinoma (NSCLC), renal cell carcinoma (RCC), bladder cancer, and Hodgkin's lymphoma. Almost at the same time, the field of adoptive cell transfer has exploded. The chimeric antigen receptor (CAR) T technology has provided strong evidence of efficacy in the treatment of B cell malignancies, and different T cell based treatments are currently under investigation for different types of tumors. In this review we will discuss the latest advances in cancer immunology and immunotherapy as well as new treatments now under development in the clinic and potential strategies that have shown promising results in preclinical models.

    Full Text Available Lung cancer is a highly malignant disease with poor prognosis, most cases are diagnosed at a very late stage. More effective medications or therapies should be developed to improve its prognosis. The advancement of tumor immunity and tumor immunosuppression facilitated the feasibility of immunotherapies for lung cancer. Ipilimumab, antibody to Programmed death-1 (PD-1, Toll-like receptor agonists, liposomal BLP25 (L- BLP25, belagenpumatucel-L, melanoma-associated antigen A3 (MAGE-A3 vaccine and talactoferrin have been proved to be effective for lung cancer through early clinical trials, most of the drugs have moved forward to phase III trials, so as to collect much higher level evidence to support the immunotherapies incorporated into the multidisciplinary treatment of lung cancer. The selection of target patients at appropriate stages, breaking down of tumor immunosuppression as well as the objective measurement of tumor response to the therapy are major challenges for the development of immunotherapies for lung cancer. The clarifying of the mechanism of immune escape led to the above drug development, and immune-senescence has already become the hotspot in this field.

    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.

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.

  1. 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

  2. Classification, staging and prognosis of lung cancer

    International Nuclear Information System (INIS)

    Lung cancer has increased in incidence throughout the twentieth century and is now the most common cancer in the Western World. It has a poor prognosis, only 10-15% of patients survive 5 years or longer. Outcome is dependent on clinical stage and cancer cell type. Lung cancer is broadly subclassified on the basis of histological features into squamous cell carcinoma, adenocarcinoma, large cell carcinoma and small cell carcinoma. The histopathological type of lung cancer correlates with tumour behaviour and prognosis. Staging based on prognosis is essential in clinical trials comparing different management strategies, and enables universal communication regarding the efficacy of different treatments in specific patient groups. The anatomic extent of disease determined either preoperatively using imaging supplemented by invasive procedures such as mediastinoscopy, and anterior mediastinotomy or following resection are described according to the T-primary tumour, N-regional lymph nodes, M-distant metastasis classification. The International System for Staging Lung Cancer attempts to group together patients with similar prognosis and treatment options. Various combinations of T, N, and M define different clinical or surgical-pathological stages (IA-IV) characterised by different survival characteristics. Refinements in staging based on imaging findings have enabled clinical staging to more accurately reflect the surgical-pathological stage and therefore more accurately predict prognosis. Recent advances including the use of positron emission tomography in combination with conventional staging promises to increase the accuracy of staging and therefore to reduce the number of invasive staging procedures and inappropriate thoracotomies

  3. Pulmonary resection after chemoradiotherapy for advanced non-small cell lung cancer. The impact of presurgical radiation therapy

    International Nuclear Information System (INIS)

    Chemoradiation therapy (CRT) is recommended as standard care for stage III non-small cell lung cancer (NSCLC), but some patients experience local recurrence after the treatment. Surgical resection after CRT involves high surgical risk, but is expected to increase the curability. This study was performed to investigate the impact of presurgical CRT on the postoperative outcome, focusing especially on the effect of radiation therapy. Twenty-six patients with stage III (N2 or T3-4) NSCLC underwent pulmonary resection after CRT. A radiation dose up to 40-70 Gy was given with concurrent chemotherapy. The morbidity, mortality and survival after surgical resection were examined. Lung resection was performed as lobectomy (73%) or pneumonectomy (19%). Postoperative complications occurred in 12 patients (morbidity 46.1%). The overall 5-year survival of the entire cohort was 69.7%. The factors associated with favorable long-term survival included a pathological complete response (CR) and mediastinal node negative condition after CRT, and microscopic complete resection. Surgical resection for stage III patients after CRT may provide a survival benefit with acceptable morbidity. The surgical morbidity may be increased by prior radiation therapy, thus, surgeons should be familiar with the available countermeasures to reduce the surgical risk. (author)

  4. 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.

    Lung cancer is responsible for 29% of cancer deaths in the United States and has very low 5-year survival rates of approximately 11% in men and 15% in women.Although the early diagnosis of lung cancer may increase the survival rate with adequate treatment,advanced lung cancers are often metastasized and receive limited benefit from therapeutic regimens.As conventional treatments for lung cancer reach their limitations,researchers have attempted to discover novel drug therapies aimed at specific targets contributing to the progression of tumorigenesis.Recent advances in systems biology have enabled the molecular biology of lung carcinogenesis to be elucidated.Our understanding of the physiologic processes of tumor development provide a means to design more effective and specific drugs with less toxicity,thereby accelerating the delivery of new drug therapies to the patient's bedside.

    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.

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 (∆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 ∆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).

    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.

  9. Radioimmunoscintigraphy in lung cancer diagnosing

    International Nuclear Information System (INIS)

    As the lung cancer is the leading cause of death from cancer at males, the exact staging is essential. Monoclonal antibodies marked with radionuclides like 131I, 111In, 99mTc, etc., allow detecting and staging the small cell lung cancer with sensibility 90%, specificity 45% and accuracy 85%. It is suggested this method to be applied simultaneously with computerized tomography. The diagnostic possibility of radioimmunoscintigraphy (RIS) in earlier detection, recurrence or metastasis as well as follow up the effect of therapy performed at patients with lung cancer are reviewed. RIS is performed with IODOMAB-R-2 (Sorin Biomedica) 131I antiCEA Mob F(ab')2, dose 92.5-185 MBq. Planar images were performed 72 hours after i.v. injection. Four patients with epidermoid squamous cell cancer were examined. Positive results were obtained at 3 patients and one false negative. In general sensitivity of radioimmunoscintigraphy of lung cancer is 75-90%. However there are difficulties at its application linked with necessity of permanent availability of radiolabelled antibodies with high specific activity at the moment of their injection. Despite all radioimmunoscintigraphy is developing as an useful diagnostic method for evaluation and follow up of lung cancer patients

  11. Localization accuracy from automatic and semi-automatic rigid registration of locally-advanced lung cancer targets during image-guided radiation therapy

    International Nuclear Information System (INIS)

    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 -3), respectively, but the smallest GTVP LE of 2.4 ± 2.1 mm was provided by rereferenced registration (p -6). Standard registration significantly reduced GTVLN centroid LE to 3.2 ± 2.5 mm (p -3) compared to bony alignment, with little additional gain offered by the other registration techniques. For simultaneous target alignment, centroid LE as low as 3.9 ± 2.7 mm and 3.8 ± 2.3 mm were achieved for the GTVP and GTVLN, respectively, using

    Purpose: To analyze primary tumor (PT) and lymph node (LN) position changes relative to each other and relative to anatomic landmarks during conventionally fractionated radiation therapy for patients with locally advanced lung cancer. Methods and Materials: In 12 patients with locally advanced non-small cell lung cancer PT, LN, carina, and 1 thoracic vertebra were manually contoured on weekly 4-dimensional fan-beam CT scans. 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.

    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.

    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.

  20. Genotypes and haplotypes of the VEGF gene and survival in locally advanced non-small cell lung cancer patients treated with chemoradiotherapy

    International Nuclear Information System (INIS)

    Vascular endothelial growth factor (VEGF) is a major mediator of angiogenesis involving in carcinogenesis, including lung cancer. We hypothesized that VEGF polymorphisms may affect survival outcomes among locally advanced non-small cell lung cancer (LA-NSCLC) patients. We genotyped three potentially functional VEGF variants [-460 T > C (rs833061), -634 G > C (rs2010963), and +936 C > T (rs3025039)] and estimated haplotypes in 124 Caucasian patients with LA-NSCLC treated with definitive radiotherapy. We used Kaplan-Meier log-rank tests, and Cox proportional hazard models to evaluate the association between VEGF variants and overall survival (OS). Gender, Karnofsky's performance scores (KPS) and clinical stage seemed to influence the OS. The variant C genotypes were independently associated with significantly improved OS (CT+CC vs. TT: adjusted hazard ratio [HR] = 0.58; 95% confidence interval [CI] = 0.37-0.92, P = 0.022), compared with the VEGF -460 TT genotype. Our study suggests that VEGF -460 C genotypes may be associated with a better survival of LA-NSCLC patients after chemoradiotherapy. Large studies are needed to confirm our findings

    @@ 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).

    Lung cancer is the leading cause of cancer-related mortality. Small cell lung cancer (SCLC) accounted for 12.95% of all lung cancer histological types in 2002. Despite trends toward modest improvement in survival, the outcome remains extremely poor. Chemotherapy is the cornerstone of treatment in SCLC. More than two-thirds of patients who succumb to lung cancer in the United States are over 65 years old. Elderly patients tolerate chemotherapy poorly and need novel therapeutic agents. Targeted...

    International Nuclear Information System (INIS)

    Objective: Prospective comparison was done on concurrent chemo-radiotherapy and sequential chemo-radiotherapy for unresectable stage III non-small cell lung cancer (NSCLC) and to evaluate three different regimens of concurrent chemo-radiotherapy. Methods: Ninety-six such patients were randomized into four groups: 1. sequential chemo-radiotherapy group received two cycles of induction chemotherapy with 40 mg/m2 of cisplatin on D 1-3, 29-31 and 100 mg/m2 of etoposide on D 1-3, 29-31 before conventional radiotherapy, 2. concurrent chemo-radiotherapy group 1 received 100 mg/m2 etoposide on D 1-3 and DDP 40 mg/m2 on D 1-3, D 29-31, iv. drip, 3. concurrent chemo-radiotherapy group 2 received concurrent chemotherapy with 40 mg/m2 of paclitaxel every Monday during conventional radiotherapy, 4. concurrent chemo-radiotherapy group 3 received concurrent chemotherapy with 40 mg/m2 of paclitaxel every Monday during three-dimensional conformal radiotherapy. All patients were irradiated with 2.0 Gy/fraction, 5 fractions/week, to a total dose of 60 -64 Gy. They all received two cycles of consolidation themotherapy with 40 mg/m2 of cisplatin on D 1-3 and 100 mg/m2 of etoposide on D 1-3. Results: The overall response rate was 67%, 71%, 71% and 79% for sequential chemo-radiotherapy group, concurrent chemo-radiotherapy group 1, 2 and 3, respectively. There was a significant difference between the concurrent chemo-radiotherapy and sequential chemo-radiotherapy(P0.05) also was the difference of toxicity (P>0.05), but the severe toxicity of concurrent chemo-radiotherapy groups 1 and 2 were higher than the sequential chemo-radio-therapy group and concurrent chemo-radiotherapy group 3. Conclusions: Better locoregional progression-free survival and overall survival of unresectable stage III non-small cell lung cancer could be achieved by concurrent chemo-radiotherapy as compared with sequential chemo-radiotherapy though at the expense of in- crease in toxicity. With the combination of

    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.

    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

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.

  11. Prospective Study of Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors Concurrent With Individualized Radiotherapy for Patients With Locally Advanced or Metastatic Non-Small-Cell Lung Cancer

    International Nuclear Information System (INIS)

    Purpose: To establish the safety profile and efficacy of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) concurrent with individualized radiotherapy (RT) in patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC). Patients and Methods: Between June 2007 and January 2010, 26 patients with Stage III/IV NSCLC were enrolled in this prospective study. These patients were treated with EGFR-TKIs (gefitinib 250 mg or erlotinib 150 mg, oral daily) concurrent with individualized RT with curative intent. The thoracic RT plans were individually designed on the basis of tumor size and normal tissue volume constraints. All patients were assessed for toxicity, and 25 patients were available for efficacy. The primary endpoints were acute toxicity, overall survival, and median survival time. The secondary endpoints included local control rate, time to tumor progression, and progression-free survival (PFS). Results: Median gross tumor volume, mean lung dose, and lung V20 were 56 cm3, 8.6 Gy, and 14%, respectively. Median thoracic radiation dose was 70 Gy at a margin of gross tumor volume (range, 42-82 Gy), and median biological equivalent dose was 105 Gy (range, 60-119 Gy). Acute skin, hematologic, esophageal, and pulmonary toxicities were acceptable and manageable. Severe adverse events included neutropenia (Grade 4, 4%) and thrombocytopenia (Grade 4, 8%), esophagitis (Grade 3, 4%), and pneumonitis (Grade 3, 4%). With a median follow-up of 10.2 months, a local control rate of 96% was achieved for thoracic tumor. Median time to progression, median PFS, and median survival time were 6.3, 10.2, and 21.8 months, respectively. The 1- and 2-year PFS rates were both 42%, and 1-, 2-, and 3-year overall survival rates were 57%, 45%, and 30%, respectively. Conclusion: Concurrent EGFR-TKIs with individualized RT shows a favorable safety profile and promising outcome, therefore serving as a therapeutic option for patients with locally advanced or

    International Nuclear Information System (INIS)

    The primary clinical application of FDG-PET is in the evaluation of patients with lung cancer and includes diagnosis, staging and restaging of non-small cell lung cancer. PET has a very high accuracy (sensitivity=97%, specificity=78%) for characterizing nodules that are indeterminate by chest radiograph and computed tomography. The major utility of PET in the evaluation of patients with lung cancer is the staging of the entire body. PET is more accurate than the conventional imaging modalities of CT and bone scans in the detection of metastatic disease. PET is accurate in the staging of the mediastinum, adrenal glands, and the skeletal system. PET is not as accurate in the detection of brain metastases because of their small size and the normal cortical accumulation

    Full Text Available Abstract Background During the past decades, numerous efforts have been made to decrease the death rate among lung cancer patients. Nonetheless, the improvement in long-term survival has been limited and lung cancer is still a devastating disease. Discussion With this article we would like to point out that survival of lung cancer could be strongly improved by controlling two pivotal prognostic factors: stage and treatment. This is corresponding with recent reports that show a decrease in lung cancer mortality by screening programs. In addition, modulation of the patient’s immune system by immunotherapy either as monotherapy or combined with conventional cancer treatments offers the prospect of tailoring treatments much more precisely and has also been shown to lead to a better response to treatment and overall survival of non-small cell lung cancer patients. Summary Since only small improvements in survival can be expected in advanced disease with the use of conventional therapies, more research should be focused on lung cancer screening programs and patient tailored immunotherapy with or without conventional therapies. If these approaches are clinically combined in a standard multidisciplinary policy we might be able to advance the survival of patients with lung cancer.

    Full Text Available Platinum-based chemotherapy is a primary treatment of choice for advanced non-small-cell lung cancer (NSCLC. Analytical methods to specifically evaluate biomarkers predictive of therapeutic efficacy have not been developed. Two randomized phase III trials of carboplatin-based chemotherapy in advanced NSCLC were used for learning and validating the predictive value of ERCC1 in situ protein levels, as measured by accurate quantitative analysis (AQUA. A novel Bayesian method was applied to identify the outcome-based threshold in the learning trial only. Overall survival (OS was assessed by Kaplan-Meier analysis with log rank testing to determine statistical significance in the validating trial. For patients treated with gemcitabine and carboplatin, the median OS was 9.5 months (95% CI 6.7 to 11.8 for the high ERCC1 group compared to 15.6 months (95% CI 11.6 to 24.8 for the low ERCC1 group in the validation trial (log rank p-value = 0.007. The hazard ratio for low ERCC1 was 0.598 (95% CI, 0.394 to 0.908; p = 0.016 relative to high ERCC1 adjusted for age, sex, and histology. Conclusions: Patients with advanced NSCLC could be stratified into high and low ERCC1 expression groups. Patients with low levels benefited from platinum-based chemotherapy, whereas those with high levels did not.

    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

    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.

    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 canc...

    A pilot study of electrochemical treatment (ECT) as a therapy for 386 patients with nonsmall cell lung cancer was undertaken. There were 103 stage 2 cases, 89 stage 3a cases, 122 stage 3b cases, and 72 stage 4 cases. Two ECT methods were used. For peripherally located lung cancer, platinum electrodes were inserted transcutaneously into the tumor under x-ray or CT guidance. For central type lung cancer or for those inoperable during thoracotomy, electrodes were inserted intraoperatively directly into the cancer. Voltage was 6--8 V, current was 40--100 mA, and electric charge was 100 coulombs per cm of tumor diameter. The number of electrodes was determined from the size of cancer mass, because the diameter of effective area around each electrode is approximately 3 cm. The short-term (6 months after ECT) results of the 386 lung cancer cases were: complete response (CR), 25.6% (99/386); partial response (PR), 46.4% (179/386); no change (NC), 15.3% (59/386); and progressive disease (PD), 12.7% (49/386). The total effective rate (CR + PR) was 72% (278/386). The 1, 3, and 5 year overall survival rates were 86.3% (333/386), 58.8% (227/386), and 29.5% (114/386), respectively. The main complication was traumatic pneumothorax, with an incidence rate of 14.8% (57/386). These clinical results show that ECT is simple, safe, effective, and minimally traumatic. ECT provides an alternative method for treating lung cancers that are conventionally inoperable, that are not responsive to chemotherapy or radiotherapy, or that cannot be resected after thoracotomy. Long-term survival rates suggest that ECT warrants further investigation.

  14. 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

  17. 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

    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.

    Full Text Available Background and objective The platinum-based plus a third-generation agent doublet chemotherapy regimen has been recommended as the standard first-line chemotherapy for advanced NSCLC by ASCO and NCCN. This study was aimed to evaluate the clinical efficacy and side effects of the Platinum plus Taxanes or other novel agent. Methods The databases PubMed, CENTRAL, EMBASE and Chinese Biomedical Literature database were retrieved by using the key words “non small cell lung cancer” or “Carcinoma, Non Small Cell Lung” so as to search the studies about the randomized controlled clinical trials, which compared Platinum plus Taxanes with Platinum plus other novel agents. A meta-analysis was conducted and the quality scores were evaluated according to the improved Jadad’s score. Results Nine randomized controlled clinical trials with 4 703 patients were included. The overall response rate and 1 year survival rate of the two groups were not significantly different (RR=1.00, 95%CI: 0.91-1.11, P=0.95; RR=0.98, 95%CI: 0.84-1.15, P=0.83. The incidence rate of grade 3-4 leukopenia, neutropenia, anemia, nausea and vomiting in TP is much lower than that in platinum plus other novel agent. Sub-group analysis showed that the overall response rate and 1 year survival rate of TP aren’t statistically different from NP or GP. The incidence rate of grade 3-4 leukopenia, neutropenia and anemia in TP is statistically lower than that in NP. The incidence rate of grade 3-4 anemia and thrombocytopenia in TP is statistically lower than that in GP. Conclusion The clinical efficacy of TP and platinum plus other novel agent is quite similar, but quite different from each other in side effects, which provides important evidence on selecting individual chemotherapy regimen.

    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.

  1. Large fraction radiotherapy plus misonidazole for treatment of advanced lung cancer: report of a phase I/II trial

    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

    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

  9. Concurrent three dimension conformal radiation therapy and chemotherapy followed by consolidation chemotherapy for locally advanced non-small cell lung cancer

    International Nuclear Information System (INIS)

    Objective: To investigate the comprehensive treatment of inoperable locally advanced non-small cell lung cancer (NSCLC), and to compare the efficacy and toxicity of concurrent chemoradiotherapy (CRT group) with those of concurrent chemoradiotherapy followed by consolidation chemotherapy (CCT group). Methods: Ninety patients with inoperable locally advanced NSCLC were randomized into CRT group or CCT group. CRT group was treated with weekly docetaxel and cisplatin based concurrent chemoradiotherapy. CCT group was treated with the same chemoradiotherapy followed by docetaxel and cisplatin based consolidation chemotherapy. For concurrent chemoradiotherapy, the total irradiation dose was 56-66 Gy given in 5-7 weeks, docetaxel 30 mg/m2 and cisplatin 20 mg/m2 were administrated on day 1, 8, 22 and 29 (≤2 hours before radiation fraction 1, 6, 16, and 21 ). For consolidation chemotherapy, docetaxel 75 mg/m2 and cisplatin 100 mg/m2 were given every three weeks to a total of two cycles. Results: For CRT group and CCT group, the response rates were 69% and 76% (P=0.480), respectively. The median progression-free survival time was 12.0 (95% CI 10.1-13.9) months and 14.5 (95% CI 11.8-17.2) months, respectively. The median survival time was 16.0 (95% CI 11.7-20.3)months and 16.0 (95% CI 13.5- 18.5 ) months, respectively. The 1-, 2- and 3-year progression-free survival rates were 56% and 62%, 12% and 24%, and 3% and 11% (P=0.044), respectively. The 1-, 2- and 3-year overall survival rates were 73% and 78%, 31% and 32%, and 20% and 21% (P=0.308), respectively. The difference of toxicity was not significant between the two group (P>0.05). Conclusions: For patients with locally advanced non-small cell lung cancer, concurrent conformal radiotherapy and chemotherapy followed by consolidation chemotherapy can improve the progression-free survival, but have few effects on overall survival and toxicity. Multicenter clinical trial with more patients should be carried out to confirm the

    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

    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 remains the most common cause of cancer related deaths in both men and women in the United States and non-small cell lung cancer (NSCLC) accounts for over 85 % of all lung cancers. Survival of these patients has not significantly altered in over 30 years. This chapter initially discusses the clinical presentation of lung cancer patients. Most patients diagnosed with lung cancer due to symptoms have advanced stage cancer. Once diagnosed, lung cancer patients need imaging studies to assess the stage of the disease before decisions regarding therapy are finalized. The most important prognostic factors are stage of the disease and performance status and these factors also determine therapy. The chapter subsequently discusses management of each stage of the disease and the impact of several pathologic, clinical factors in personalizing therapy for each individual patient. Transition from chemotherapy for every patient to a more personalized approach based on histology and molecular markers has occurred in the management of advanced stage NSCLC. It is expected that such a personalized approach will extend to all stages of NSCLC and will likely improve the outcomes of all NSCLC patients. PMID:26703806

    Participatory and patient-centered approaches to cancer research have been highlighted as the most appropriate means of engaging patients in the conduct of clinical research. However, there is a paucity of patient-centered outcomes research (PCOR) on lung cancer. Previous studies seeking to define lung cancer treatment success have generally not included patients' and caregivers' perceptions and views in treatment decision-making. Additionally, little is known about effective strategies for the engagement of lung cancer patients in PCOR. We sought to gain insights into the perceptions of patients, caregivers, and providers on lung cancer treatment success, as well as on strategies for patient engagement in lung cancer PCOR. Four focus groups were conducted with provider, patient, and caregiver participants from four cancer centers in Nebraska and South Dakota. A total of 36 providers, patients, and caregivers participated in this study. Patients and caregivers confirmed that survival alone should not be the measure of lung cancer treatment success and that definitions of treatment success should emphasize factors such as effective clinical guidance throughout treatment, symptom management, functionality, and quality of life. Clinician participants noted that the definition of treatment success evolved over time and appeared to be linked to patients' experiences with chemotherapy. Participants identified barriers to and facilitators of research participation and suggested strategies for the recruitment and retention of research participants. Our study indicates that patients can successfully play active and engaged roles in clinical research, ranging from participant to partner. Judging from the enthusiasm of our focus group attendees, patients and caregivers want to participate and be engaged in clinical research. PMID:24744120

  17. A phase II trial of accelerated hypofractionated three-dimensional conformal radiation therapy in locally advanced non-small cell lung cancer

    International Nuclear Information System (INIS)

    Purpose: The aim of this study is to evaluate the safety and efficacy of accelerated hypofractionated radiotherapy (HypoRT) combined with sequential chemotherapy in locally advanced non-small cell lung cancer (NSCLC). Materials and methods: A total of 34 patients with stage III NSCLC were enrolled. All patients received accelerated HypoRT (initially 50 Gy/20 fractions, then a fraction dose of 3 Gy) using three-dimensional conformal radiation therapy (3D-CRT), omitting elective nodal irradiation (ENI), to a total dose of 65-68 Gy. All patients received two cycles of induction chemotherapy; 1-2 cycles of consolidation chemotherapy were given to 31 patients. The primary outcome measure was a profile of radiation toxicity. The secondary endpoints included overall survival (OS), progression-free survival (PFS), locoregional PFS (LR-PFS) and the pattern of initial failure. Results: Radiation toxicity was minimal. The median and 3-year OS, PFS were 19.0 months, 32.1%; 10.0 months, 29.8%, respectively. The 1-, 2-, and 3-year LR-PFS were 69.6%, 60.9% and 60.9%, respectively. No patient experienced isolated elective nodal failure as the first site of failure. Conclusion: This study suggests that accelerated HypoRT using 3D-CRT omitting ENI can be used in combination with sequential chemotherapy in locally advanced NSCLC.

    Full Text Available Background. Huachansu, the sterilized water extract of Bufo bufo gargarizans toad skin, is used in China to alleviate the side-effects and enhance the therapeutic effect of chemotherapy in advanced non-small-cell lung cancer (NSCLC. We conducted a meta-analysis to assess Huachansu’s efficacy. Methods. We extensively searched electronic databases (CENTRAL, EMBASE, MEDLINE, CBM, Cochrane Library, CNKI, CEBM, WFDP, CSCD, CSTD, and IPA for randomized controlled trials containing Huachansu plus chemotherapy as the test group and chemotherapy as the control group. Seventeen trials were selected based on the selection criteria. The pooled relative ratio (RR of indicators with 95% confidence interval (95% CI was calculated for efficacy evaluation. Results. The meta-analysis demonstrated a statistically significant improvement in objective tumor response, one-year survival, Karnofsky performance status, pain relief, and alleviation of severe side-effects (nausea and vomiting, leukocytopenia in the test group as compared to the control group, but no significant difference in thrombocytopenia. Conclusions. This study demonstrated the efficacy of Huachansu combined with chemotherapy in the treatment of advanced NSCLC. However, limitations exist and high-quality trials are needed for further verification.

    Full Text Available Background. sequential chemotherapy can maintain dose intensity and preclude cumulative toxicity by increasing drug diversity. Purpose. to investigate the toxicity and efficacy of the sequential regimen of gemcitabine followed by paclitaxel in first line advanced stage non-small cell lung cancer (NSCLC patients with good performance status (PS. Patients and methods. gemcitabine 1250 mg/m2 was administered on day 1 and 8 of course 1 and 2; Paclitaxel 150 mg/m2 on day 1 and 8 of course 3 and 4. Primary endpoint was response rate (RR, secondary endpoints toxicity and time to progression (TTP. Results. Of the 21 patients (median age 56, range 38–80 years; 62% males, 38% females 10% (2/21 had stage IIIB, 90% (19/21 stage IV, 15% PS 0, 85% PS 1. 20% of patients had a partial response, 30% stable disease, 50% progressive disease. Median TTP was 12 weeks (range 6–52 weeks, median overall survival (OS 8 months (range 1–27 months, 1-year survival was 33%. One patient had grade 3 hematological toxicity, 2 patients a grade 3 peripheral neuropathy. Conclusions. sequential administration of gemcitabine followed by paclitaxel in first line treatment of advanced NSCLC had a favourable toxicity profile, a median TTP and OS comparable with other sequential trials and might , therefore, be a treatment option for NSCLC patients with high ERCC1 expression.

    Our aim was to evaluate the clinical effectiveness of chemotherapy treatments currently licensed in Europe and recommended by the National Institute for Health and Care Excellence (NICE) for the first-line treatment of adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC). A systematic search of MEDLINE, EMBASE and the Cochrane Library for randomised controlled trials (RCTs) published from 2001 to 2010 was carried out. Relative treatment effects for overall survival (OS) and progression-free survival (PFS) were estimated using standard meta-analysis and mixed treatment comparison methodology. A total of 23 RCTs were included: 18 trials compared platinum-based chemotherapy, two compared pemetrexed and three compared gefitinib. There are no statistically significant differences in OS between any of the four third-generation chemotherapy regimens. There is statistically significant evidence that pemetrexed+platinum increases OS compared with gemcitabine+platinum. There are no statistically significant differences in OS between gefitinib and docetaxel+platinum or between gefitinib and paclitaxel+platinum. There is a statistically significant improvement in PFS with gefitinib compared with docetaxel+platinum and gefitinib compared with paclitaxel+platinum. Due to reduced generic pricing, third-generation chemotherapy regimens (except vinorelbine) are still competitive options for most patients. This research provides a comprehensive evidence base, which clinicians and decision-makers can use when deciding on the optimal first-line chemotherapy treatment regimen for patients diagnosed with locally advanced or metastatic NSCLC.

    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.

    The aim of this study was to evaluate the efficacy and safety of the combination of docetaxel (TXT) plus tamoxifen (TAM) in advanced non-small-cell lung cancer (NSCLC) patients who had received platinum-based first-line chemotherapy. A total of 120 advanced NSCLC patients pretreated with platinum-based chemotherapy were randomized into two treatment groups (the TXT and TXT+TAM groups) in a 1 : 1 ratio. Reversal of P-glycoprotein (P-gp) expression, tumor response, progression-free survival, overall survival, and safety were evaluated on an intention-to-treat basis. The median number of cycles of allocated chemotherapy was four in each treatment group (range: 2-6 cycles). The overall response rate and disease control rate in the TXT+TAM group were significantly higher than those in the TXT group (36.7 vs. 15.0% for overall response rate, P=0.007; 85.0 vs. 68.3% for disease control rate, P=0.031). The combination of TXT and TAM could effectively reverse P-gp expression in tumor tissues and provide a significant survival benefit for advanced NSCLC patients compared with TXT alone (11.6 vs. 9.1 months, P=0.030). In addition, in the TXT+TAM group, patients achieving P-gp reversal had a significantly greater median progression-free survival and overall survival than nonreversal patients. Furthermore, the combined therapy showed a safety profile comparable to that of TXT. The combination of TXT and TAM may be an effective and safe treatment option for advanced NSCLC patients who have already developed P-gp-mediated multidrug resistance. PMID:26882453

    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.

    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.

  7. Risk of second primary lung cancer in women after radiotherapy for breast cancer

    International Nuclear Information System (INIS)

    Background: Several epidemiological studies have reported increased risks of second lung cancers after breast cancer irradiation. In this study we assessed the effects of the delivered radiation dose to the lung and the risk of second primary lung cancer. Methods: We conducted a nested case–control study of second lung cancer in a population based cohort of 23,627 early breast cancer patients treated with post-operative radiotherapy from 1982 to 2007. The cohort included 151 cases diagnosed with second primary lung cancer and 443 controls. Individual dose-reconstructions were performed and the delivered dose to the center of the second lung tumor and the comparable location for the controls were estimated, based on the patient specific radiotherapy charts. Results: The median age at breast cancer diagnosis was 54 years (range 34–74). The median time from breast cancer treatment to second lung cancer diagnosis was 12 years (range 1–26 years). 91% of the cases were categorized as ever smokers vs. 40% among the controls. For patients diagnosed with a second primary lung cancer five or more years after breast cancer treatment the rate of lung cancer increased linearly with 8.5% per Gray (95% confidence interval = 3.1–23.3%; p < 0.001). This rate was enhanced for ever smokers with an excess rate of 17.3% per Gray (95% CI = 4.5–54%; p < 0.005). Conclusions: Second lung cancer after radiotherapy for early breast cancer is associated with the delivered dose to the lung. Although the absolute risk is relative low, the growing number of long-time survivors after breast cancer treatment highlights the need for advances in normal tissue sparing radiation techniques

    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.

  10. Imaging of hypoxia with 18F-FAZA PET in patients with locally advanced non-small cell lung cancer treated with definitive chemoradiotherapy

    International Nuclear Information System (INIS)

    For many cancers, tumour hypoxia is an adverse prognostic factor, and increases chemoradiation resistance; its importance in non-small cell lung cancer (NSCLC) is unproven. This study evaluated tumoural hypoxia using fluoroazomycin arabinoside (18F-FAZA) positron emission tomography (PET) scans among patients with locoregionally advanced NSCLC treated with definitive chemoradiation. Patients with stage IIIA-IIIB NSCLC underwent 18F-FAZA PET scans and 18F-2-deoxyglucose (FDG)-PET scans within 4 weeks of commencing and 8 weeks following conventionally-fractionated concurrent platinum-based chemoradiation (60Gy). Intra-lesional hypoxic volumes of the primary and nodal masses were compared with FDG-PET metabolic volumes. Baseline tumoural hypoxia was correlated with disease free survival (DFS). Seventeen patients underwent pre-treatment 18F-FAZA PET and FDG-PET scans. Intra-lesional hypoxia was identified on 11 scans (65%). Baseline lesional hypoxic volumes were consistently smaller than FDG-PET volumes (P=0.012). There was no statistical difference between the mean FDG-PET volumes in patients with or without baseline hypoxia (P=0.38). Eight patients with baseline hypoxia had post treatment 18F-FAZA scans and 6 of these (75%) had resolution of imageable hypoxia following chemoradiation. The DFS was not significantly different between the hypoxic or non-hypoxic groups (median 0.8 years and 1.3 years respectively, P=0.42). Intra-lesional hypoxia, as detected by 18F-FAZA PET, was present in 65% of patients with locally-advanced NSCLC and resolved in the majority of patients following chemoradiation. Larger studies are required to evaluate the prognostic significance of the presence and resolution of hypoxia assessed by PET in NSCLC.

  11. Measurement of tumor volume by PET to evaluate prognosis in patients with advanced non-small cell lung cancer treated by non-surgical therapy

    International Nuclear Information System (INIS)

    Background: Patients with advanced non-small cell lung cancer (NSCLC) seem to have disparity in prognosis. Accurate prediction of prognosis could be useful in the future to predict individual risk and to develop more aggressive or alternative treatment strategies. Purpose: To evaluate the prognostic value of metabolic tumor volume (MTV) measured by 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) in patients with NSCLC. Material and Methods: We retrospectively reviewed 120 patients with pathologically proven NSCLC (61 squamous cell carcinomas and 59 adenocarcinomas) who underwent pretreatment 18F-FDG PET. MTV and maximum standardized uptake value (SUVmax) for the primary tumors were measured by 18F-FDG PET. Pretreatment variables (age, sex, American Joint Committee on Cancer [AJCC] stage, histological type, SUVmax, and MTV) were analyzed to identify their correlation with two-year survival. To further evaluate and compare the predictive value of PET parameters, MTV, and SUVmax, time-dependent receiver-operating characteristic curve (ROC) analysis was used. Results: In the univariate analysis, AJCC stage, histological type, MTV, and SUVmax of primary tumor were significant predictors of survival. On multivariate analysis, independent prognostic factors associated with decreased two-year survival were AJCC stage (hazard ratio [HR] 2.236, P 0.003), histological type (HR 2.038, P = 0. 004), and MTV (HR 1.016, P 0.001). SUVmax was not a significant factor (HR 0.96, P = 0.490). On time-dependent ROC analysis, MTV showed good predictive performance for two-year survival consistently better than SUVmax. Conclusion: MTV, a volumetric parameter of 18F-FDG PET, is an important independent prognostic factor for survival and a better predictor of survival than SUVmax for the primary tumor in patients with advanced NSCLC

    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.

  17. Chemoradiotherapy for youngster lung cancer

    International Nuclear Information System (INIS)

    Objective: To define the clinico-pathologic characteristics and survival of young-robust patients (2 vs 70 mg/m2, P<0.001), and more cycles of chemotherapy 6 vs 4, P<0.001) were observed in the youngster group. There was no difference between the two groups in family history of cancer, cigarette smoking, weight loss, and KPS. The median survival intervals of all stages (10 months vs 12 months), and the 2-and 5-year survival rates (11.1% vs 23.1% and 3.1% vs 5.4%) were comparable (P=0.090) between them. For stage IIIb, there was a trend that young patients would give better outcome than the older ones with median survivals of 11 months to 9 months and the 2-year survivals of 3.8% to 0% (P=0.071). Conclusions: The different clinico-pathologic features of the young lung cancer patients are confirmed from that of old patients, but without any survival disparity. In order to enhance our understanding and reduce the mis-diagnosis rate, it is rational to define the lung cancer in relative young people as the youngster lung cancer, which may be beneficial to the clinical practice

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

  19. Magnetic resonance imaging in peripheral lung cancer

    International Nuclear Information System (INIS)

    We evaluated the usefulness of magnetic resonance imaging (MRI) by comparison of MRI studies and pathological findings in lung cancer patients. From May 2005 to May 2006, 52 lung cancer patients underwent surgical operation in our division. Forty-five patients, each with a preoperatively recognized peripheral lung lesion underwent the MRI study. Short TI inversion recovery (STIR), high b-value diffusion-weighted imaging (DWI) with free breathing scanning and dynamic MRI studies were performed. There was no statistically significant difference between adenocarcinoma (n=35) and other carcinomas (n=10) on MRI findings. Twenty-seven adenocarcinomas (less than 30 mm in diameter) were histologically diagnosed as follows: 9 patients with bronchioloalveolar carcinoma (BAC), 12 patients with advanced BAC, and 6 non-BAC cases (adenocarcinoma without a BAC component) group. When the lesions demonstrated a strong enhancement (steep type) on dynamic studies or showed a strong signal (score 4) intensity on DWI, we judged them to be positive (indicating invasion). Sensitivity, specificity and accuracy were 94.4%, 66.6%, and 85.2%, respectively. The MRI studies permitted the acquisition of more detailed information on peripheral lung adenocarcinomas, and high b-value DWI is valuable as a supporting tool in evaluating the grade of malignancy.

    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.

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.

  3. 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

    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.

    Full Text Available Introduction: The effects of first-line single-agent chemotherapy on overall survival (OS might be confounded by subsequent treatments in elderly patients with nonsmall cell lung cancer (NSCLC. We, therefore, aimed to evaluate whether progression-free survival (PFS, postprogression survival (PPS, or tumor response might be a valid surrogate endpoint for OS in this patient population. Patients and Methods: We retrospectively reviewed the clinical data of 58 elderly patients with advanced NSCLC, who received first-line single-agent cytotoxic chemotherapy at our institution between October 2003 and November 2013. The relationships of PFS, PPS, and tumor response with OS were individually analyzed. Results: The study cohort included 46 men and 12 women with a median age of 79 years (range: 75-87 years. There were 30 adenocarcinomas, 22 squamous cell carcinomas, and 6 other histologic types with 1 stage IIIA, 9 IIIB, and 48 IV cases. The performance status (PS scores were 0, 1, and 2 in 18, 35, and 5 patients, respectively. The median PFS and OS were 2.8 and 5.4 months, respectively. Our analyses revealed a strong correlation of PPS and PFS with OS, whereas that between tumor shrinkage and OS was weak. Tumor stage and PS after initial treatment were significantly associated with PPS. Individual analysis indicated that PPS might serve as a surrogate for OS in elderly patients with advanced NSCLC receiving first-line single-agent chemotherapy. Conclusion: Our findings suggested that the disease course after progression following first-line single-agent chemotherapy might influence the OS of elderly patients with advanced NSCLC.

    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.

    A platinum-based two-drug regimen is currently the standard of care for patients with advanced non-small-cell lung cancer (NSCLC). However, chemotherapy-induced side effects still remain a significant clinical problem. Astragalus polysaccharide (APS) is a polysaccharide isolated from the radix of astragalus membranaceus, a commonly used herbal compound in traditional Chinese medicine. APS was reported to increase tumor response, stabilize and improve performance status, and reduce chemotherapy toxicity. We designed this trial to determine whether APS injection integrated with vinorelbine and cisplatin (VC) offered an improved QOL over VC for patients with advanced NSCLC. Secondary objectives were tumor response, toxicity, and survival results. One hundred thirty-six patients with histologically or cytologically confirmed NSCLC were enrolled in this study from May 2008 to March 2010. Patients were randomized to receive either VC (VC arm) or VC combined with APS (VC-APS arm). The objective response rate of was 42.64% in the VC-APS arm and 36.76% in the VC arm. The difference was not statistically significant (P = 0.483). Median survival time was 10.7 and 10.2 months (P = 0.76) in VC-APS arm and VC arm, with 1-year survival rates of 35.3 and 32.4% (P = 0.717), respectively. After 3 cycles of treatment, there were significant differences in the overall patient QOL (P = 0.003), physical function (P = 0.01), fatigue (P pain (P = 0.007), and loss of appetite (P = 0.023) between the two study groups. In summary, we have proved that the treatment of APS integrated with VC had significantly improved QOL in patients with advanced NSCLC compared with VC alone. PMID:21928106

    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.

    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.

    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...

    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 Societal perceptions may factor into the high rates of nontreatment in patients with lung cancer. To determine whether bias exists toward lung cancer, a study using the Implicit Association Test method of inferring subconscious attitudes and stereotypes from participant reaction times to visual cues was initiated. Participants were primarily recruited from an online survey panel based on US census data. Explicit attitudes regarding lung and breast cancer were derived from participants' ratings (n = 1778 regarding what they thought patients experienced in terms of guilt, shame, and hope (descriptive statements and from participants' opinions regarding whether patients ought to experience such feelings (normative statements. Participants' responses to descriptive and normative statements about lung cancer were compared with responses to statements about breast cancer. Analyses of responses revealed that the participants were more likely to agree with negative descriptive and normative statements about lung cancer than breast cancer (P<0.001. Furthermore, participants had significantly stronger implicit negative associations with lung cancer compared with breast cancer; mean response times in the lung cancer/negative conditions were significantly shorter than in the lung cancer/positive conditions (P<0.001. Patients, caregivers, healthcare providers, and members of the general public had comparable levels of negative implicit attitudes toward lung cancer. These results show that lung cancer was stigmatized by patients, caregivers, healthcare professionals, and the general public. Further research is needed to investigate whether implicit and explicit attitudes and stereotypes affect patient care.

    Here we studied cell-free plasma DNA (cfDNA) collected from subjects with advanced lung cancer whose tumors had developed resistance to the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) AZD9291. We first performed next-generation sequencing of cfDNA from seven subjects and detected an acquired EGFR C797S mutation in one; expression of this mutant EGFR construct in a cell line rendered it resistant to AZD9291. We then performed droplet digital PCR on serial cfDNA specimens collected from 15 AZD9291-treated subjects. All were positive for T790M prior to treatment, but at resistance three molecular subtypes emerged: 6 cases acquired the C797S mutation, 5 cases maintained the T790M mutation but did not acquire the C797S mutation, and 4 cases lost the T790M mutation despite detecting of the underlying EGFR activating mutation. Our findings provide insight into the diversity of mechanisms through which tumors acquire resistance to AZD9291 and highlight the need for therapies able to overcome resistance mediated by EGFR C797S.

  2. The correlation between clinical factors and radiation pneumonitis in advanced stage non-small-cell lung cancer treated with concurrent radiochemotherapy

    International Nuclear Information System (INIS)

    Objective: To evaluate clinical factors as predictors of radiation pneumonitis (RP)in advanced stage non-small cell lung cancer (NSCLC) patients treated with concurrent radio chemotherapy when gross tumor volume is 70 Gy. Methods: Data of 84 patients with histologically proved NSCLC treated with 3DCRT or IMRT were collected. To evaluate the correlation between clinical parameters and radiation pneumonitis (RP). The clinical parameters were considered: pathological type, therapy agents, age,gender, stage, karnofsky performance status (KPS), smoking status, diabetes, chronic obstructive pulmonary disease (COPD). Results: The occurrence of grade 1, 2 RP was 63%, 33%, respectively. In univariate analysis, diabetes was significantly associated with RP of ≥ grade 1(χ2 =4.03, P = 0.045)and ≥grade 2(χ2 = 15.59, P =0.000). KPS was significantly associated with RP of ≥grade 1(χ2 =3.98, P = 0.046)and ≥grade 2(χ2 = 5.21, P = 0.023). In logistic multivariate analysis, diabetes was significantly associated with RP of ≥grade 1(χ2 =5.50, P =0.019)and ≥grade 2(χ2 = 12.92, P =0.000). KPS was significantly associated with RP of ≥ grade 1(χ2 = 6.29, P = 0.012)and ≥ grade 2(χ2 = 6.61, P =0.010). Conclusion: The definite statistical significant risk factors of RP are diabetes and KPS. (authors)

  3. CXCR4 expression on circulating pan-cytokeratin positive cells is associated with survival in patients with advanced non-small cell lung cancer

    International Nuclear Information System (INIS)

    The CXC chemokine, CXCL12, and its receptor, CXCR4 promote metastases of a variety of solid tumors, including non-small cell lung cancer (NSCLC). The expression of CXCR4 on tumor cells may represent a critical biomarker for their propensity to metastasize. This study was performed to evaluate the hypothesis that co-expression of pan-cytokeratin and CXCR4 may be a prognostic marker for patients with advanced NSCLC. We evaluated CXCR4 levels on circulating pan-cytokeratin positive cells from patients with NSCLC. NSCLC tumor and metastases were also assessed for the presence of CXCR4. Pan-cytokeratin positive cells were increased in the circulation of patients with NSCLC, as compared to normal control subjects. Patients with pan-cytokeratin +/CXCR4+ = 2,500 cells/ml had a significant improvement in median survival when compared with patients with pan-cytokeratin +/CXCR4+ >2,500 cells/ml (not achieved versus 14 weeks). CXCR4 expression was found on NSCLC tumors and at sites of tumor metastasis. This study suggests that CXCR4 may be a prognostic marker in NSCLC, and provides hypothesis-generating results, which may be important in determining metastatic potential. In future studies, we will prospectively evaluate the prognostic significance of pan-cytokeratin/CXCR4+ cells, and determine the mechanisms involved in the regulation of CXCR4 expression on tumor cells in a larger patient population

    International Nuclear Information System (INIS)

    Tracheobronchial reconstructive procedures have been done for lung cancer in 26 patients. Twenty-four of the 26 cases were advanced cases in stage 3. Six of the 26 cases were irradiated preoperatively. The survival rate for 26 patients at three years was 43.4% and that for 20 patients without preoperative irradiation at three years was 58.0%. Three of the six preoperative irradiated cases died within two months after operation due to anastomotic dehiscences it appears that the use of preoperative irradiation resulted in increase in complications.

Methods: We performed a broad search of PubMed for relevant trials. Prospective randomized trials evaluating therapy with or without anti-VEGF agents in patients with advanced NSCLC were included for analysis. Data on VTEs and ATEs were extracted. The overall incidence, Peto odds ratio (Peto OR, and 95% confidence intervals (CIs were pooled according to the heterogeneity of included trials. Results: A total of 13,436 patients from 23 trials were included for analysis. Our results showed that anti-VEGF agents significantly increased the risk of developing high-grade ATEs (Peto OR: 1.44, 95% CI: 1.00–2.07, P=0.048, but not for all-grade ATEs (Peto OR: 0.94, 95% CI: 0.56–1.59, P=0.82 compared with controls.

  6. 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 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.

  12. 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

    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

  14. Radiodiagnosis of lung cancer

    International Nuclear Information System (INIS)

    Adenocarcinoma of the lung occurring in the periphery grows as superficial spreading and/or deeply invading parts in the alveolar area. The superficial spreading part develops on the internal surface of alveoli, and when this part shows a monolayer arrangement of tumor cells and is low in height, not accompanied by mucus production, the shadow is faint, and does not cause deformation or deviation of the pre-existing structures. When tumor cell have amultilayer, substantial or polyoid arrangement and marked mucus production, the shadow is dense with a clear margin and no change or occasional compression of the pre-existing architecture. The deeply invading part develops on the alveolar wall, manifesting itself primarily as interstitial hyperplasia and fibrosis. Roentogenologically, the part shows a slightly high density and convergence in the pre-existing structures. Each adenocarcinoma shows an architecture consisting of these progressing parts combined and is similar roentogenologically. Therefore, X-ray features such as the density of tumor shadow, marginal properties and presence or absence and the intensity of convergence demonstrate the rough architecture and mode and stage of tumors.

    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.

    The International Association for the Study of Lung Cancer (IASLC) has conducted an extensive initiative to inform the revision of the lung cancer staging system. This involved development of an international database along with extensive analysis of a large population of patients and their prognoses. This article reviews the recommendations of the IASLC International Staging Committee for the definitions for the TNM descriptors and the stage grouping in the new non-small cell lung cancer staging system.

    Endotracheal metastases of primary lung cancer are rare. Only one case of tracheal metastasis from small cell lung cancer has been reported in literature. Here, we report a rare case of a 45-year-old woman who was admitted for sudden-onset breathlessness with respiratory failure and required ventilatory support. Endotracheal growth was identified during bronchoscopy, and biopsy revealed endotracheal metastasis of small cell lung cancer.

    The incidence of female lung cancer in developed countries has been increasing since 1950 and particularly in France where the cigarettes consumption has also increased. Since 1980, a growing number of epidemiological surveys have pinpointed the risk of female lung cancer related to smoking. Consecutively, a debate on gender differences in lung cancer risk has appeared, but still in progress nowadays. The reproductive factors could explain these differences. In order to have recent and reliab...
