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

Full Text Available Bronchoscopic techniques have seen significant advances in the last decade. The development and refinement of different types of endobronchial ultrasound and navigation systems have led to improved diagnostic yield and lung cancer staging capabilities. The complication rate of these minimally invasive procedures is extremely low as compared to traditional transthoracic needle biopsy and surgical sampling. These advances augment the safe array of methods utilized in the work up and management algorithms of lung cancer.

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.

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.

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 has become the leading cause of cancer deaths, with nonsmall cell lung cancer (NSCLC) accounting for around 80% of lung cancer cases. Chemotherapy is the main conventional therapy for advanced NSCLC. However, the disease control achieved with classical chemotherapy in advanced NSCLC is usually restricted to only a few months. Thus, sustaining the therapeutic effect of first-line chemotherapy is an important problem that requires study. Maintenance therapy is given for patients wit...

Conclusion The lung function decreases in the patients with lung cancer. VC, FEV1, FVC, PEF, PEF%, MVV, residual volume/total lung capacity were correlated with survival time in patients with advanced lung cancer. The pulmonary function indexs were important marker of prognosis in patients with lung cancer.
Full Text Available Definitive radiochemotherapy is the standard treatment for many patients with locally advanced nonsmall cell lung cancer (NSCLC. Treatment outcomes have improved over the last decades. Several treatment regimens have been shown effective and safe. This review summarises the results of significant studies between 1996 and 2015 on concomitant and sequential radiochemotherapy regimens and radiation dose per fraction. Beside therapy regimens, optimised radiotherapy planning is indispensable to improve outcome and minimise radiation-induced toxicity. An insight into the rationale of radiotherapy planning for stage III NSCLC is also provided.

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.

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

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
The results of a controlled clinical trial in the treatment of advanced primary lung cancer are presented. There were 39 patients who entered the present study that was conducted at the Thoracic Surgery Departament of the A.C. Camargo Hospital of the Antonio Prudente Foundation of Sao Paulo, Brazil. The patients were divided in two groups 1) - Radiotherapy with Cobalt 60 plus Chemotherapy. 2) - Chemotherapy only. The radiotherapy was provided by the split dose technic (6.000 rads in 3 cycles of 2.000 rads each). The chemotherapy consisted of the following drugs (5 FU, Metil hidrazina, Methotrexate, Actinomycin D, Oncovin, Cytoxan) administered in 16 cycles, aiming the synchronous funtional blockade. There was no statistically significant difference in survival of the two groups, ie, the first with 19,3 weeks and the second group with 14,6 weeks. (Author)
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.

Full Text Available Lung cancer has been one of the most common and the highest mortality rates malignant tumors at home and abroad. Sustained angiogenesis was not only the characteristic of malignant tumors, but also the foundation of tumor proliferation, invasion, recurrence and metastasis, it was also one of the hot spots of treatments in lung cancer biology currently. Integrins played an important part in tumor angiogenesis. Arg-Gly-Asp (RGD peptides could combine with integrins specifically, and the application of radionuclide-labeled RGD molecular probes enabled imaging of tumor blood vessels to reflect its changes. The lung cancer imaging of RGD peptides at home and abroad in recent years was reviewed in this article.

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

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

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.
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

Lung cancer is the leading cause of cancer death in the United States, and the majority of diagnoses are made in former smokers. Although avoidance of tobacco abuse and smoking cessation clearly will have the greatest impact on lung cancer development, effective chemoprevention could prove to be more effective than treatment of established, advanced-stage disease. Chemoprevention is the use of dietary or pharmaceutical agents to reverse or block the carcinogenic process and has been successfu...

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.

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

Receptor for advanced glycation end products (RAGE) is associated with the pathogenesis of cancer progression. The pathological effects mediated through RAGE are physiologically inhibited by soluble RAGE (sRAGE). The aim of the present study was to identify the expression of the sRAGE, RAGE and RAGE ligands in serum samples and lung cancer tissue obtained from lung cancer patients. Using ELISA and immunohistochemistry, it was observed that the sRAGE levels were downregulated in the serum, the...
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)

Full Text Available Raúl Barrera-Rodriguez,1 Jorge Morales-Fuentes2 1Biochemistry and Environmental Medicine Laboratory, National Institute of Respiratory Disease, 2Lung Cancer Medical Service, National Institute of Respiratory Disease, Tlalpan, Mexico City, Distrito Federal, Mexico Both authors contributed equally to this workAbstract: Recent biological advances in tumor research provide clear evidence that lung cancer in females is different from that in males. 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

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

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

The management of advanced non-small-cell lung cancer (a-nsclc) is currently undergoing one of its rare paradigm shifts. Just as the nihilism of the 1970s gave way to the empiricism of the 1980s and 1990s, so the current decade has seen the first truly rational therapies based on informed design. In addition, molecular markers and traditional parameters can now be combined to provide a framework of knowledge that will guide the application of not just the new therapies, but also the older one...

Full Text Available Intractable advanced lung cancer can be treated palliatively with photodynamic therapy (PDT combined with chemotherapy to remove central and peripheral (lobar or segmental bronchi bronchial stenosis and obstruction. 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.

This study examined the differences of opinion between cancer patients and caregivers with regard to treatment and care decisions. 184 advanced lung cancer patients and 171 primary caregivers were recruited as a convenience sample from hospitals in Cleveland, Ohio. A telephone interview was conducted to collect data using a semi-structured questionnaire. Nonparametric tests and regression analysis were performed. The findings showed that patients and caregivers reported significant disagreement on three main issues: trade-off between treatment side effects and benefits; reporting treatment side effects to physicians, and hospice care. Caregivers were more concerned about patient's quality of life and more willing to discuss hospice issues than were patients (p caregivers (p caregiver disagreement about treatment and care decisions and its significant adverse impact on both patients and caregivers.

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.

Full Text Available Background and objective As there is a sharp increase in the incidence of lung cancer in women in recent years, it has brought broad concerns with its unique clinical and epidemiological characteristics and better prognosis. 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.

BACKGROUND: Lung cancer is one of the most common malignant diseases worldwide and associated with considerable morbidity and mortality. New agents targeting the epidermal growth factor system are emerging, but only a subgroup of the patients will benefit from the therapy. Cell free DNA (cf......DNA) in the blood allows for tumour specific analyses, including KRAS-mutations, and the aim of the study was to investigate the possible prognostic value of plasma mutated KRAS (pmKRAS) in patients with non-small cell lung cancer (NSCLC). MATERIAL AND METHODS: Patients with newly diagnosed, advanced NSCLC eligible......-KRAS mutation had a significantly shorter OS and PFS compared to the wild type (WT) patients (median OS 4.8 months versus 9.5 months, HR 1.87, 95% CI 1.23-2.84, p=0.0002 and median PFS 3.0 months versus 5.6 months, HR 1.60, 95% CI 1.09-2.37, p=0.0043). A multivariate Cox regression analysis confirmed...

Epigenetic deregulation of gene function has been strongly implicated in carcinogenesis and is one of the mechanisms contributing to the development of lung cancer. The inherent reversibility of epigenetic alterations makes them viable therapeutic targets. Here, we review the therapeutic implications of epigenetic changes in lung cancer, and recent advances in therapeutic strategies targeting DNA methylation and histone acetylation.

Brain metastases are frequently encountered in patients with non-small cell lung cancer (NSCLC) and are a significant cause of morbidity and mortality. Antiangiogenesis therapy plays a major role in the management of brain metastases in lung cancer. Bevacizumab have become the novel method for the treatment of lung cancer with brain metastases beyond the whole brain radiation therapy, stereotactic radiosurgery and chemotherapy. Recently, more and more studies and trials laid emphasis on the bevacizumab for NSCLC with brain metastases treatment. The key point is the efficacy and safety. In this review, bevacizumab therapy of NSCLC with brain metastases were summarized. PMID:27561800

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.
Full Text Available Lung cancer with brain metastasis was 23% to 65%, and is the most common type in brain metastasis tumors with the poor prognosis. At present, diagnosis and treatment of brain metastases from lung carcinoma and its molecular mechanism have become one hot spot of amount researches. Here, we made a systematic review of the progress of the clinical features, diagnosis and treatment of brain metastases from lung and its molecular mechanism.
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

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 rad...

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.
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

Chemoradiotherapy is the current standard of care in patients with advanced inoperable stage IIIA or IIIB non-small cell lung cancer (NSCLC). Three-dimensional radiotherapy (3DCRT) has been a trusted method for a long time and has well-known drawbacks, most of which could be improved by Intensity Modulated Radiotherapy (IMRT). IMRT is not currently the standard treatment of locally advanced NSCLC, but almost all patients could benefit to a degree in organ at risk sparing, dose coverage confor...

Image-guided interventions for palliative treatment of lung cancer is aimed at local control of advanced disease in the affected lung, adjacent mediastinal structures, or distant metastatic sites. These procedures include endovascular therapy for superior vena cava syndrome, bronchial artery embolization for hemoptysis associated with lung cancer, and ablation of osseous metastasis. Pathophysiology, clinical pres...
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

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

Lung cancer has been transformed from a rare disease into a global problem and public health issue. The etiologic factors of lung cancer become more complex along with industrialization, urbanization, and environmental pollution around the world. Currently, the control of lung cancer has attracted worldwide attention. Studies on the epidemiologic characteristics of lung cancer and its relative risk factors have played an important role in the tertiary prevention of lung cancer and in exploring new ways of diagnosis and treatment. This article reviews the current evolution of the epidemiology of lung cancer. PMID:27261907
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.
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
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)
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.

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

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

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.
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

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.
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.

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)

Lung cancer is the leading cause of cancer-related deaths worldwide. The relatively poor cure rate in lung cancer patients has been associated with a resistance to chemotherapy and radiation that is at least in part related to defects in cellular apoptotic machinery. Exploitation of another form of cell death, autophagy, has the capacity to improve the therapeutic gain of current therapies. In an effort to develop novel treatment strategies to enhance the therapeutic ratio for lung cancer, we...

Every patient undergoing curative treatment for primary lung cancer is a candidate for metachronous lung cancer, with a reported risk of 5% per year. The majority of cases are stage I patients. Patients who undergo resection for lung cancer should be followed regularly. A metachronous lung cancer that develops as bilateral synchronous lung cancer is very rare.

Full Text Available Metastatic tumors involving the brain are an important complication in the overall management of non-small cell lung cancers. Surgery and radiation remain the cornerstones of the therapy, however, the burgeoning knowledge of tumor biology has facilitated the entry of systemically administered therapies into the clinic. This review mainly summarizes the current applications of these data to surgery, radiation therapy, chemotherapy and targeted therapy.

Imaging plays a vital role in the management of non-small cell lung cancer including diagnosis, staging and follow-up. CT and magnetic resonance imaging (MRI) are used in staging and provide anatomical information but have well known limitations in differentiating reactive from malignant nodes, and fibrosis from active disease and in defining the extent of invasion. MRI with its superior soft tissue contrast provides optimal information on brachial plexus and central nervous system involvemen...
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.
This study describes prognostic factors for lung cancer spread and recurrence, as well as subsequent risk of death from the disease. The investigators observed that regardless of cancer stage, grade, or type of lung cancer, patients in the study were more
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.

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.

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.

Despite several decades of intensive effort to improve the imaging techniques for lung cancer diagnosis and treatment, primary lung cancer is still the number one cause of cancer death in the United States and worldwide. The major causes of this high mortality rate are distant metastasis evident at diagnosis and ineffective treatment for locally advanced disease. Indeed, approximately forty percent of newly diagnosed lung cancer patients have distant metastasis. Currently, the only potential ...

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
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)

INTRODUCTION: Significant problems in clinician-patient communication have been described in the oncology literatures. Advanced stage non-small lung cancer a devastating disease, can cause the communication between survivors, significant others, and clinicians to falter. To date, however, no studies have used qualitative methods to examine experiential aspects of living with non-small cell lung cancer. Nor have any studies evaluated the tools survivors might use to repair some of the damage c...
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.

Lung cancer has now surpassed breast cancer as the leading cause of cancer deaths in American women. In 1986, 49,000 women were diagnosed as having lung cancer; only 16 percent of them will survive 5 years or more. Cigarette smoking is unquestionably the leading contributing factor. Large numbers of women took up cigarette smoking during and after World War II. The grim aftermath has taken 20 years to surface--between 1950 and 1985, lung cancer deaths in women increased 500 percent. Even wors...

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.
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.

Full Text Available With the development of pharmacogenomics and pharmacogenetics, personal therapy based on genes has become one of the most effective ways to enhance chemotherapeutic effect on non-small cell lung cancer (NSCLC patients. Much attention has been paid to validate the predictive biomarkers of chemotherapy in order to guide chemotherapy and enhance effect in general. Gemcitabine is one of the common agents treating NSCLC recently. This review is mainly about the recent reports on potential biomarkers of Gemcitabine in tailored therapy of NSCLC.

Most patients with lung cancer are diagnosed when they present with symptoms, they have advanced stage disease, and curative treatment is no longer an option. An effective screening test has long been desired for early detection with the goal of reducing mortality from lung cancer. Sputum cytology, chest radiography, and computed tomography (CT) scan have been studied as potential screening tests. The National Lung Screening Trial (NLST) demonstrated a 20% reduction in mortality with low-dose CT (LDCT) screening, and guidelines now endorse annual LDCT for those at high risk. Implementation of screening is underway with the desire that the benefits be seen in clinical practice outside of a research study format. Concerns include management of false positives, cost, incidental findings, radiation exposure, and overdiagnosis. Studies continue to evaluate LDCT screening and use of biomarkers in risk assessment and diagnosis in attempt to further improve outcomes for patients with lung cancer. PMID:27158468
Full Text Available OBJECTIVE: To investigate the clinical significance of the expression of MHC class I chain-related gene A (MICA in patients with advanced non-small cell lung cancer and explore the relationship between MICA expression and the efficacy of cytokine-induced killer cell (CIK therapy for treating advanced non-small cell lung cancer. METHODS: We obtained data on 222 patients with advanced non-small cell lung cancer, including data on MICA expression, age, gender, ECOG score, pathological type, stage, treatment history (including 38 patients who were given autologous CIK cell infusion, and overall survival (OS. MICA expression in lung cancer tissue was evaluated by immunohistochemical staining. Analyses of MICA expression, and CIK therapy association with survival outcomes were performed using Cox proportional models, Kaplan-Meier methods, and the log-rank test. RESULT: s MICA was expressed in both membrane and cytoplasm. MICA expression correlated with the stage of lung cancer, ECOG score, gender and age. Multivariate COX regression analysis showed that the expression of MICA was an independent prognostic factor of advanced non-small cell lung cancer (p = 0.002. In subgroup analysis, we divided the 222 patients into CIK and control groups. In the CIK group, the medium OS (mOS of patients with a high expression of MICA was longer than in those with low expression of MICA (27 months vs. 13 months. In the control group, the mOS in patients with a high expression of MICA was shorter than in patients with low MICA expression (9 months vs. 18 months. COX regression analysis showed that the MICA expression affects the effect of CIK therapy (p<0.0001. CONCLUSION: 1 The high expression of MICA is one of the indicators of a poor prognosis for advanced non-small cell lung cancer patients. 2 The high expression of MICA might be one of the predictive factors for successful CIK therapy.

Objective:To analyze the clinical efficacy of Liujunzi decoction combined with EP chemotherapy regiment for advanced non-small cell lung cancer.Methods:A total of 72 cases of patients with non-small cell lung cancer were included in the study, the range of patients’ treatment was from August 2012 to October 2014, and according to different treatment, they were divided into observation group 36 cases and control group 36 cases. Control group received EP chemotherapy, observation group received Liujunzi decoction combined with EP chemotherapy regiment, and then differences in serum tumor marker levels, tumor tissue-related protein levels, PDCD5, Nrf2, HIF-1α and GLUT1 levels, and levels of VEGF, GSTs, TSGF and so on were compared between two groups.Results:Serum CY211, SCC, NSE, CEA and CA199 levels of observation group after treatment were lower than those of control group; TUBB3, ERCC-1, MT and P53 expression levels of observation group after treatment were lower while Mcll and Fbw7 expression levels were higher; PDCD5 level of observation group after treatment was higher than that of control group while Nrf2, HIF-1α and GLUT1 levels were lower than those of control group; CD4+CD25+Foxp3+ Treg/CD4+ T, VEGF, GSTs and TSGF values of observation group after treatment were lower than those of control group. Conclusion:Liujunzi decoction combined with EP chemotherapy regiment for patients with advanced non-small cell lung cancer can effectively inhibit tumor cell proliferation as well as invasion and metastasis, is helpful for disease control and prognosis improvement, and has positive clinical significance.
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
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.
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

Lung cancer is the leading cause of cancer death in the United States, and the majority of diagnoses are made in former smokers. While avoidance of tobacco abuse and smoking cessation clearly will have the greatest impact on lung cancer development, effective chemoprevention could prove to be more effective than treatment of established disease. Chemoprevention is the use of dietary or pharmaceutical agents to reverse or inhibit the carcinogenic process and has been successfully applied to co...

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
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

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

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.

Full Text Available Background and objective Erlotinib, a selective inhibitor of epidermal growth factor receptor tyrosine kinase, has been approved effective in local advanced or metastatic non-small cell lung cancer (NSCLC. The aim of this study was to evaluate the efficacy and safety of erlotinib for the treatment of advanced NSCLC. Methods Ninety-two patients with advanced NSCLC who had failed or not tolerated or refused chemotherapy received 150 mg oral doses of erlotinib once daily until the disease progression or intolerable toxicity. Results Among the 92 NSCLC patients, 2 patient got complete response (2.2%, 22 partial response (23.9%, 48 stable disease (52.2% and 20 progressive disease (21.7%. The overall response rate and the disease controlled rate of erlotinib was 26.1% (24/92 and 78.3% (72/92, respectively. The response rate of erlotinib were significantly higher in rash and ECOG 0-1 than no rash and ECOG ≥ 2. The disease controlled rate of erlotinib was significantly higher in female and non-smokers than male and smokers (P < 0.05. The response rate of erlotinib did not show significant differences within pathological type or previous treatment. The most common side effects were rash and diarrhea with 84.8% and 31.5%, respectively, but usually were mild. Conclusion Erlotinib is effective and safe in the treatment of advanced NSCLC patients.

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

Major advances in the WB-MRI in the initial evaluation and follow-up of patients with lung cancer have been performed in recent years. Multicentric studies using different magnet systems are necessary to confirm these promising results.
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)
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.

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 sp...

Radiation therapy for early stage lung cancer is a promising modality. It has been traditionally used in patients not considered candidates for standard surgical resection. However, its role has been changing rapidly since the introduction of new and advanced technology, especially in tumor tracking, image guidance, and radiation delivery. Stereotactic radiation therapy is one such advancement that has shown excellent local control rates and promising survival in early stage lung cancer. In a...
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
Chang, Joe Y.
When used to treat lung cancer, intensity-modulated radiotherapy (IMRT) can deliver higher dose to the targets and spare more critical organs in lung cancer than can 3D conformal radiotherapy (3DCRT). However, tumor-motion management and optimized radiotherapy planning based on four-dimensional computed tomography (4D CT) scanning are crucial to maximize the benefit of IMRT and to eliminate or minimize potential uncertainties. This article summarizes these strategies and reviews published fin...

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
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%). There was no difference between the
Lung cancer is the leading cause of cancer deaths worldwide as well as in Korea. A recent National Lung Screening Trial in U.S. revealed that low-dose CT (LDCT) screening reduced lung cancer specific mortality by 20% in high risk individuals as compared to chest radiograph screening. Based on this evidence, several expert societies in U.S. and Korean multisociety collaborative committee developed guidelines for recommendation of lung cancer screening using annual LDCT in high risk populations. In most of the societies high risk groups are defined as persons aged 55 to 74 years, who are current smokers with history of smoking of more than 30 packs per year or ex-smokers, who quit smoking up to 15 or more years ago. The benefits of LDCT screening are modestly higher than the harms in high risk individuals. The harms included a high rate of false-positive findings, over-diagnosis and radiation-related deaths. Invasive diagnostic procedure due to false positive findings may lead to complications. LDCT should be performed in qualified hospitals and interpreted by expert radiologists. Recently, the American College of Radiology released the current version of Lung cancer CT screening Reporting and Data Systems. Education and actions to stop smoking must be offered to current smokers

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

Fundamental to the diagnosis of lung cancer in CT scans is the detection and interpretation of lung nodules. As the capabilities of CT scanners have advanced, higher levels of spatial resolution reveal tinier lung abnormalities. While not all detected lung nodules should be reported, radiologists strive to detect all nodules that might have relevance to cancer diagnosis. Although medium to large lung nodules are detected consistently, inter-reader agreement and reader sensitivity for lung nod...

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.
Lung cancer harms people's health or even lives severely. Currently, the morbidity and mortality of lung cancer are ascending all over the world. Accounting for 38.08% of malignant tumor caused death in male and 16% in female in cities,ranking top in both sex. Especially, the therapy of non-small cell lung cancer has not been obviously improved for many years. Recently, sodium/iodide transporter gene transfection and the therapy of molecular target drugs mediated radionuclide are being taken into account and become the new research directions in treatment of advanced lung cancer patients with the development of technology and theory for medical molecular biology and the new knowledge of lung cancer's pathogenesis.

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.
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)
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.
