More than 50% of non-small cell lung cancer (NSCLC) cases harbor an actionable mutation, and molecular testing at different intervals can help in personalized and targeted treatment. Core tissue biopsy and needle biopsy done at the time of diagnosis/disease progression are interventional, time-consuming and can affect the patients adversely. Noninterventional biomarker testing by liquid biopsy promises to revolutionize advanced stage cancer screening. The present report was formulated based on an expert panel meeting of renowned oncologists who gave their opinions for minimally invasive liquid biopsy to detect targetable molecular biomarkers in advanced NSCLC cases. An exhaustive literature search was done to support their recommendations. Clinical utility of minimally invasive liquid biopsy, for detection of molecular biomarkers in advanced stage NSCLC patients, was broadly discussed by the key opinion leaders.

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

Stage I non-small-cell lung cancer is potentially curable, yet older patients undergo treatment at lower rates than younger patients. This analysis sought to describe the treatment outcomes of nonagenarians with stage I non-small-cell lung cancer to better guide treatment decisions in this population. The National Cancer DataBase was queried for patients age ≥90 years old with stage I non-small-cell lung cancer (tumors ≤4 cm). Patients were divided into 3 groups: local therapy, other therapy, or no treatment. The primary outcomes were 5-year overall and relative survival. Of the 616 patients identified, 33% (202) were treated with local therapy, 34% (207) were treated with other therapy, and 34% (207) underwent no treatment. Compared with local therapy, overall mortality was significantly higher with no treatment (hazard ratio 2.50, 95% confidence interval, 1.95-3.21) and other therapy (hazard ratio 1.43, 95% confidence interval, 1.11-1.83). The 5-year relative survival was 81% for local therapy, 49% for other therapy, and 32% for no treatment (P < .0001). Nonagenarians managed with local therapy for stage I non-small-cell lung cancer (tumors ≤4 cm) have better overall survival than those receiving other therapy or no treatment and should be considered for treatment with either operation or stereotactic body radiation therapy if able to tolerate treatment.

Advances in immunotherapy for non-small cell lung cancer.

PubMed

Reckamp, Karen L

2015-12-01

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

Endothelial progenitor cells are capable of contributing to neovascularization in tumours. In patients with either malignant or transudative pleural effusion, we tested the presence of pleural endothelial progenitor cells. We also measured the number of endothelial progenitor cells in post-surgery pleural drainage of either patients with early non-small-cell lung cancer or control patients with benign lung disease undergoing pulmonary resection. The prospective influence of post-surgery pleural-drainage endothelial progenitor cells on cancer recurrence/survival was investigated. Pleural endothelial progenitor cell levels were quantified by fluorescence-activated cell sorting analysis in pleural effusion of 15 patients with late-stage non-small-cell lung cancer with pleural involvement and in 15 control patients with congestive heart failure. Also, pleural-drainage endothelial progenitor cells were measured in pleural-drainage fluid 48 h after surgery in 64 patients with early-stage non-small-cell lung cancer and 20 benign lung disease patients undergoing pulmonary resection. Cancer recurrence and survival was evaluated in patients with high pleural-drainage endothelial progenitor cell levels. The number of pleural endothelial progenitor cells was higher in non-small-cell lung cancer pleural effusion than in transudative pleural effusion. Also, pleural-drainage endothelial progenitor cell levels were higher in patients with non-small-cell lung cancer than in patients with benign lung disease undergoing pulmonary resection (P < 0.05). Non-small-cell lung cancer patients with high pleural-drainage endothelial progenitor cell levels had a significantly 4.9 higher rate of cancer recurrence/death than patients with lower pleural-drainage endothelial progenitor cell levels, irrespective of confounders. Endothelial progenitor cells are present in the pleural effusion and are higher in patients with late-stage non-small-cell lung cancer with pleural involvement than in

Concurrent chemoradiotherapy is the standard treatment for locally advanced Stage III non-small cell lung cancer in patients with a good performance status and minimal weight loss. This study aimed to define subgroups with different survival outcomes and identify correlations with the radiation-related toxicities. We retrospectively reviewed 381 locally advanced Stage III non-small cell lung cancer patients with a good performance status or weight loss of <10% who received concurrent chemoradiotherapy between 2004 and 2011. Three-dimensional conformal radiotherapy was administered once daily, combined with weekly chemotherapy. The Kaplan-Meier method was used for survival comparison and Cox regression for multivariate analysis. Multivariate analysis was performed using all variables with P values <0.1 from the univariate analysis. Median survival of all patients was 24 months. Age > 75 years, the diffusion lung capacity for carbon monoxide ≤80%, gross tumor volume ≥100 cm(3) and subcarinal nodal involvement were the statistically significant predictive factors for poor overall survival both in univariate and multivariate analyses. Patients were classified into four groups according to these four predictive factors. The median survival times were 36, 29, 18 and 14 months in Groups I, II, III and IV, respectively (P < 0.001). Rates of esophageal or lung toxicity ≥Grade 3 were 5.9, 14.1, 12.5 and 22.2%, respectively. The radiotherapy interruption rate differed significantly between the prognostic subgroups; 8.8, 15.4, 22.7 and 30.6%, respectively (P = 0.017). Severe toxicity and interruption of radiotherapy were more frequent in patients with multiple adverse predictive factors. To maintain the survival benefit in patients with concurrent chemoradiotherapy, strategies to reduce treatment-related toxicities need to be deeply considered. © The Author 2015.

2014-01-01

Objectives Conventional video-assisted thoracoscopic (VATS) lobectomy for advanced lung cancer is a feasible and safe surgery in experienced centers. The aim of this study is to assess the feasibility of uniportal VATS approach in the treatment of advanced non-small cell lung cancer (NSCLC) and compare the perioperative outcomes and survival with those in early-stage tumors operated through the uniportal approach. Methods From June 2010 to December 2012, we performed 163 uniportal VATS major pulmonary resections. Only NSCLC cases were included in this study (130 cases). Patients were divided into two groups: (A) early stage and (B) advanced cases (>5 cm, T3 or T4, or tumors requiring neoadjuvant treatment). A descriptive and retrospective study was performed, comparing perioperative outcomes and survival obtained in both groups. A survival analysis was performed with Kaplan-Meier curves and the log-rank test was used to compare survival between patients with early and advanced stages. Results A total of 130 cases were included in the study: 87 (A) vs. 43 (B) patients (conversion rate 1.1 vs. 6.5%, P=0.119). Mean global age was 64.9 years and 73.8% were men. The patient demographic data was similar in both groups. Upper lobectomies (A, 52 vs. B, 21 patients) and anatomic segmentectomies (A, 4 vs. B, 0) were more frequent in group A while pneumonectomy was more frequent in B (A, 1 vs. B, 6 patients). Surgical time was longer (144.9±41.3 vs. 183.2±48.9, P<0.001), and median number of lymph nodes (14 vs. 16, P=0.004) were statistically higher in advanced cases. Median number of nodal stations (5 vs. 5, P=0.165), days of chest tube (2 vs. 2, P=0.098), HOS (3 vs. 3, P=0.072), and rate of complications (17.2% vs. 14%, P=0.075) were similar in both groups. One patient died on the 58th postoperative day. The 30-month survival rate was 90% for the early stage group and 74% for advanced cases Conclusions Uniportal VATS lobectomy for advanced cases of NSCLC is a safe and

Lung cancer is the leading cause of cancer-related death worldwide. Current clinical screening methods to detect lung cancer are expensive and associated with many complications. Raman spectroscopy is a spectroscopic technique that offers a convenient method to gain molecular information about biological samples. In this study, we measured the serum Raman spectral intensity of healthy volunteers and patients with different stages of non-small cell lung cancer. The purpose of this study was to evaluate the application of serum laser Raman spectroscopy as a low cost alternative method in the screening and staging of non-small cell lung cancer (NSCLC). The Raman spectra of the sera of peripheral venous blood were measured with a LabRAM HR 800 confocal Micro Raman spectrometer for individuals from five groups including 14 healthy volunteers (control group), 23 patients with stage I NSCLC (stage I group), 24 patients with stage II NSCLC (stage II group), 19 patients with stage III NSCLC (stage III group), 11 patients with stage IV NSCLC (stage IV group). Each serum sample was measured 3 times at different spots and the average spectra represented the signal of Raman spectra in each case. The Raman spectrum signal data of the five groups were statistically analyzed by analysis of variance (ANOVA), principal component analysis (PCA), linear discriminant analysis (LDA), and cross-validation. Raman spectral intensity was sequentially reduced in serum samples from control group, stage I group, stage II group and stage III/IV group. The strongest peak intensity was observed in the control group, and the weakest one was found in the stage III/IV group at bands of 848 cm -1 , 999 cm -1 , 1152 cm -1 , 1446 cm -1 and 1658 cm -1 (P < 0.05). Linear discriminant analysis showed that the sensitivity to identify healthy people, stage I, stage II, and stage III/IV NSCLC was 86%, 65%, 75%, and 87%, respectively; the specificity was 95%, 94%, 88%, and 93%, respectively; and

Controversy remains over the appropriate postoperative management for patients with stage Ia non-small cell lung cancer who underwent complete surgical resection as a result of a heterogeneous prognosis. We aimed to identify the predictive factors for recurrence in these patients to aid in the decision making. We reviewed 344 patients with stage Ia non-small cell lung cancer to analyze the associations between recurrence-free survival and the following clinicopathologic variables: age, gender, smoking history, family history, preoperative serum carcinoembryonic antigen level, type of surgical resection, tumor location, tumor histology, lymphovascular invasion, tumor differentiation, and pathologic T status. Cox multivariate survival analysis revealed that central tumor location (P=.019), stage T1b (P=.006), high histologic grade (including large cell carcinoma, solid predominant, micropapillary predominant, and invasive mucinous adenocarcinoma, P=.007), poor differentiation (P=.022), and lymphovascular invasion (P=.035) were independently associated with recurrence-free survival. A nomogram for predicting the probability of 3-year recurrence-free survival was developed using the 5 variables. This model shows good calibration, reasonable discrimination (concordance index=0.733), and small overfitting (2.6%) demonstrated by bootstrapping. We developed a clinicopathologic prediction model for postoperative recurrence in stage Ia non-small cell lung cancer. This model can help with the selection of appropriate postoperative therapeutic strategies for these patients. Copyright © 2014 The American Association for Thoracic Surgery.

Present and future treatment of advanced non-small cell lung cancer.

Crinò, Lucio; Cappuzzo, Federico

Platinum-based chemotherapy is considered the standard treatment for advanced non-small cell lung cancer (NSCLC). Several phase II trials using cisplatin in combination with new chemotherapeutic agents, such as gemcitabine, the taxanes, vinorelbine, and irinotecan, showed impressive response rates and suggested an improvement in overall survival. Large phase III trials comparing these second-generation cisplatin regimens indicated a substantial equivalence of new combinations, marginally improving the outcome of patients over the first-generation platinum-based regimens. Phase III trials have not yet shown dramatic advantages for either multiple-drug regimens, with nonoverlapping mechanisms of action and toxicity, or nonplatinum doublets, with efficacy and/or toxicity profiles superior to those of platinum-based chemotherapy. Chemotherapy in advanced non-small cell lung cancer has reached a plateau, and it is clear that new approaches are required. These should include prevention, screening, and early detection, and the use of novel treatments based on our understanding of the biology and molecular biology of this disease.

Lung cancer ranks as the top cancer worldwide in terms of incidence and constitutes a major health problem. About 90% of lung cancer cases are diagnosed at advance stage where treatment is not available. Despite evidence that lung cancer screening improves survival, guidelines for lung cancer screening are still a subject for debate. In Saudi Arabia, only 14% of lung cancers are diagnosed at early stage and researches on survival and its predictors are lacking. This overview analysis was conducted on predictors of lung cancer mortality according to the two major cancer types, small-cell lung cancers (SCLCs) and non-small cell lung cancers (NSCLCs) in Saudi Arabia. A secondary data analysis was performed on small-cell lung cancers (SCLCs) and Non-small cell lung cancers (NSCLCs) registered in the Saudi Cancer Registry (SCR) for the period 2009-2013 to estimate predictors of mortality for both lung cancer types. A total of 404 cases (197 SCLC and 207 NSCLC) were included in the analysis, all Saudi nationals. A total of 213 (52.75%) deaths occurred among lung cancer patients, 108 (54.82%) among SCLCs and 105 (50.72%) among NCSLCs. Three quarter of patients are diagnosis with advance stage for both SCLC & NSCLC. Univariate analysis revealed higher mean age at diagnosis in dead patients compared to alive patients for SCLCs (p=0.04); but not NSCLCs, a lower mortality for NSCLCs diagnosed in 2013 (p=0.025) and a significant difference in stage of tumor (p=0.006) and (p=0.035) for both SCLC and NSCLC respectively. In multiple logistic regression, stage of tumor was a strong predictor of mortality, where distant metastasis increased morality by 6-fold (OR=5.87, 95% CI: 2.01 - 17.19) in SCLC and by 3-fold (OR=3.29, 95% CI: 1.22 - 8.85) in NSCLC, compared to localized tumors. Those with NSCLC who were diagnosed in 2013 were less likely to die by 64% compared to NSCLC diagnosed in 2009 (OR=0.36, 95% CI: 0.14 - 0.93). Age, sex, topography and laterality were not associated with

OBJECTIVES: This study assessed the importance of socioeconomic status, race, and likelihood of receiving surgery in explaining mortality among patients with stage-I non-small cell lung cancer. METHODS: Analyses focused on Black and White individuals 75 years of age and younger (n = 5189) diagnosed between 1980 and 1982 with stage-I non-small cell lung cancer in Detroit, San Francisco, and Seattle. The main outcome measure was months of survival after diagnosis. RESULTS: Patients in the highest income decile were 45% more likely to receive surgical treatment and 102% more likely to attain 5-year survival than those in the lowest decile. Whites were 20% more likely to undergo surgery than Blacks and 31% more likely to survive 5 years. Multivariate procedures controlling for age and sex confirmed these observations. CONCLUSIONS: Socioeconomic status and race appear to independently influence likelihood of survival. Failure to receive surgery explains much excess mortality. PMID:9807536

Lung cancer is the leading cause of cancer-related mortality in men and the second leading cause in women. Approximately 85% of lung cancer patients have non-small cell lung cancer (NSCLC), and most present with advanced stage at diagnosis. The current treatment for such patients is chemoradiation (CRT) provided concurrently preferably or sequentially with chemotherapy, using conventionally fractionated radiation doses in the range of 60 to 66 Gy in 30 to 33 fractions. An individual patient data based metaanalysis has shown that in good performance status (PS), concomitant CRT was associated to improved survival by 4.5% compared to sequential combination (5-year survival rate of 15.1% and 10.6% respectively). In the recent years, improvement of modern technique of radiotherapy (RT) and new chemotherapy drugs may be favorable for the patients. Furthermore, the positron emission tomography-computed tomography (PET-CT) contributes to improved delineation of RT especially in terms of nodal involvement. Improving outcomes for patients with stage III disease remains a challenge, this review will address the questions that are considered fundamental to improving outcome in patients with stage III NSCLC.

Cigarette smoking is a well-known cause of interstitial lung disease (ILD), pulmonary emphysema and lung cancer. Coexisting pulmonary disease can affect prognosis in patients with lung cancer. The aim of this study was to determine the influence of pulmonary disease on outcomes in patients with a smoking history who had undergone surgery for pathological Stage I non-small-cell lung cancer. Medical records of 257 patients with a smoking history who underwent surgery for pathological Stage I non-small-cell lung cancer between June 2009 and December 2014 were reviewed. Coexisting ILDs were evaluated using high-resolution computed tomography. The degree of pulmonary emphysema was determined using image analysis software according to the Goddard classification. The impact of clinicopathological factors on outcome was evaluated. Among the 257 patients, ILDs were detected via high-resolution computed tomography in 60 (23.3%) patients; of these, usual interstitial pneumonia (UIP) patterns and non-UIP patterns were seen in 25 (9.7%) and 35 (13.6%) patients, respectively. The degree of pulmonary emphysema was classified as none, mild and moderate and included 50 (19.5%), 162 (63.0%) and 45 (17.5%) patients, respectively. The 5-year overall survival, cancer-specific survival and relapse-free survival were 80.7%, 88.0% and 74.9%, respectively, during a median follow-up period of 50.5 months. In multivariate analysis, the presence of a UIP pattern was shown to be an independent risk factor for poor outcome. The presence of a UIP-pattern ILD on high-resolution computed tomography images was shown to be a risk factor for poor outcome in patients with a smoking history who had undergone surgery for pathological Stage I non-small-cell lung cancer.

Coiled-coil domain containing (CCDC) family members enhance tumor cell proliferation, and high CCDC protein levels correlate with unfavorable prognoses. Limited research demonstrated that CCDC106 may promote the degradation of p53/TP53 protein and inhibit its transactivity. The present study demonstrated that CCDC106 expression correlates with advanced TNM stage (P = 0.008), positive regional lymph node metastasis (P < 0.001), and poor overall survival (P < 0.001) in 183 non-small cell lung cancer cases. A549 and H1299 cells were selected as representative of CCDC106-low and CCDC106-high expressing cell lines, respectively. CCDC106 overexpression promoted A549 cell proliferation and xenograft tumor growth in nude mice, while siRNA-mediated CCDC106 knockdown inhibited H1299 cell proliferation. CCDC106 promoted AKT phosphorylation and upregulated the cell cycle-regulating proteins Cyclin A2 and Cyclin B1. Cell proliferation promoted by CCDC106 via Cyclin A2 and Cyclin B1 was rescued by treatment with the AKT inhibitor, LY294002. Our studies revealed that CCDC106 is associated with non-small cell lung cancer progression and unfavorable prognosis. CCDC106 enhanced Cyclin A2 and Cyclin B1 expression and promoted A549 and H1299 cell proliferation, which depended on AKT signaling. These results suggest that CCDC106 may be a novel target for lung cancer treatment.

Cancer immunotherapy for non-small cell lung cancer began around 1970 with nonspecific immunomodulators and cytokine therapies. This has since developed into cell therapy including lymphokine-activated killer cells(LAK)and tumor infiltrating lymphocytes(TIL), as well as cancer vaccine therapy. However, no clear indication of effectiveness has been reported. Despite the high expectation over the effectiveness of cancer vaccine therapy, the treatment strategy was deemed unsuccessful, and focus turned to the study of immune escape mechanism, which is now regarded as standard treatment for non-small cell lung cancer. With the advent of immune checkpoint inhibitors, cancer immunotherapy has finally become a standard treatment for non-small cell lung cancer. There are still several obstacles to overcome including the identification of a predictive biomarker for improved efficacy, as well as the establishment of multidrug or multimodality combination therapy. PD-L1 expression is currently used as a predictive biomarker for anti-PD-1 therapy, but does not meet the expectations of the aimed results. Although tumor mutation burden is considered another promising biomarker, there remain clinical problems, for example the need of next generation sequencer. It was reported that combination therapy of immune checkpoint inhibitor after chemoradiation therapy was also effective. However, it remains unclear of what is required to further improve the clinical effects. In this article, we will review the history of cancer immunotherapy for non-small cell lung cancer and discuss the future prospects.

Background: Stage IV non-small cell lung cancer (NSCLC) is a treatable, but not curable, clinical entity in patients given the diagnosis at a time when their performance status (PS) remains good. Methods: A systematic literature review was performed to update the previous edition of the American College of Chest Physicians Lung Cancer Guidelines. Results: The use of pemetrexed should be restricted to patients with nonsquamous histology. Similarly, bevacizumab in combination with chemotherapy (and as continuation maintenance) should be restricted to patients with nonsquamous histology and an Eastern Cooperative Oncology Group (ECOG) PS of 0 to 1; however, the data now suggest it is safe to use in those patients with treated and controlled brain metastases. Data at this time are insufficient regarding the safety of bevacizumab in patients receiving therapeutic anticoagulation who have an ECOG PS of 2. The role of cetuximab added to chemotherapy remains uncertain and its routine use cannot be recommended. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors as first-line therapy are the recommended treatment of those patients identified as having an EGFR mutation. The use of maintenance therapy with either pemetrexed or erlotinib should be considered after four cycles of first-line therapy in those patients without evidence of disease progression. The use of second- and third-line therapy in stage IV NSCLC is recommended in those patients retaining a good PS; however, the benefit of therapy beyond the third-line setting has not been demonstrated. In the elderly and in patients with a poor PS, the use of two-drug, platinum-based regimens is preferred. Palliative care should be initiated early in the course of therapy for stage IV NSCLC. Conclusions: Significant advances continue to be made, and the treatment of stage IV NSCLC has become nuanced and specific for particular histologic subtypes and clinical patient characteristics and according to the

Stage IA non-small-cell lung cancer cases have been recognized as having a low risk of relapse; however, occasionally, relapse may occur. To predict clinical outcome in Stage IA non-small-cell lung cancer patients, we searched for chimeric transcripts that can be used as biomarkers and identified a novel chimeric transcript, RUNX1-GLRX5, comprising RUNX1, a transcription factor, and GLRX5. This chimera was detected in approximately half of the investigated Stage IA non-small-cell lung cancer patients (44/104 cases, 42.3%). Although there was no significant difference in the overall survival rate between RUNX1-GLRX5-positive and -negative cases (P = 0.088), a significantly lower relapse rate was observed in the RUNX1-GLRX5-positive cases (P = 0.039), indicating that this chimera can be used as a biomarker for good prognosis in Stage IA patients. Detection of the RUNX1-GLRX5 chimeric transcript may therefore be useful for the determination of a postoperative treatment plan for Stage IA non-small-cell lung cancer patients. © The Author 2015.

Identifying metastatic tumor growth at an early stage has been one of the biggest challenges in the treatment of lung cancer. By genetic lineage tracing approach in a conditional model of Non-Small Cell Lung Cancer (NSCLC) in mice, we demonstrate that cystic lesions represent an early stage of metastatic invasion. We generated a mouse model for NSCLC which incorporated a heritable DsRed fluorescent tag driven by the ubiquitous CAG promoter in the alveolar type II cells of the lung. We found early cystic lesions in a secondary organ (liver) that lacked the expression of bona fide lung makers namely Scgb1a1 and surfactant protein C Sftpc and were DsRed positive hence identifying lung as their source of origin. This demonstrates the significant potential of alveolar type II cells in orchestrating the process of metastasis, rendering it as one of the target cell types of the lung of therapeutic importance in human NSCLC.

TRIM28 is a universal corepressor for Kruppel-associated box zinc finger proteins. In this study, we demonstrated the expression of TRIM28 gene was significantly higher in cancerous tissues than in noncancerous tissues (P < 0.001). TRIM28 knockdown resulted in a decrease in cell proliferation in liquid media as well as in soft agar. The proliferation rate was impaired and the cell cycle progression was inhibited after knockdown of TRIM28 in non-small cell lung cancer cell lines PAa and SK-MES-1. We used real-time polymerase chain reaction to detect circulating cancer cells in 138 non-small cell lung cancer patients. The overall positive detection rate was 30.4% (42 of 138) in peripheral blood of NSCLC patients and was 29.9% (29 of 97) in early-stage patients. In a 70-month follow-up study, 20 of 29 patients (69.0%) in TRIM28 positive group had recurrence and/or metastasis, significantly higher (P = 0.004) than in the TRIM28 negative group (25 of 68, 36.8%). In addition, non-small cell lung cancer patients whose circulating cancer cells expressed TRIM28 suffered shorter tumor-specific survival compared with those with absent TRIM28 expression (P < 0.001). Results of our study showed that TRIM28 provides a survival advantage to lung cancer cells and may be a new marker to predict metastasis and prognosis in early-stage non-small cell lung cancer patients.

Icotinib is the first oral epidermal growth factor receptor (EGFR) tyrosine kinase receptor inhibitor, which has been proven to exert significant inhibitory effects on non-small cell lung cancer in vitro. Clinical evidence has showed that the efficacy of Icotinib on retreating advanced non-small cell lung cancer is comparable to Gefitinib. However, different phenotypes of EGFR can affect the therapeutic outcomes of EGFR tyrosine kinase receptor inhibitor. Therefore, our study focused on efficacy and safety of Icotinib in patients with advanced non-small cell lung cancer of different EGPR phenotypes. Clinical data of patients with advanced non-small cell lung cancer who received Icotinib treatment from August, 2011 to May, 2013 were retrospectively analyzed. Kaplan-Meier analysis was used for survival analysis and comparison. 18 wild-type EGFR and 51 mutant type were found in a total of 69 patients. Objective response rate of patients with mutant type EGFR was 54.9 % and disease control rate was 86.3 %. Objective response rate of wild-type patients was 11.1 % (P = 0.0013 vs mutant type), disease control rate was 50.0 % (P = 0.0017). Median progression-free survival (PFS) of mutant type and wild-type patients were 9.7 and 2.6 months, respectively (P < 0.001). Median PFS of exon 19 mutated mutant patients was 11.3 months, mean PFS of exon 21 L858R mutated mutant patients was 8.7 months (P = 0.3145). Median overall survival (OS) of EGFR mutated patients had not reached. OS time of 13 wild-type patients was 12.9 months (P < 0.001). The common adverse reactions of Icotinib included rash, diarrhea, itching skin with occurrence rates of 24.6 % (17/69), 13.0 % (9/69), and 11.6 % (8/69), respectively. Most adverse reactions were grade I-II. Icotinib has great efficacy in EGFR mutated patients, making it an optimal regimen to treat EGFR mutated patients. Furthermore, most of adverse reactions associated with Icotinib treatment were tolerable.

The incidence of gastrointestinal metastases from lung cancer is higher than previously thought as they have been reported in 2-14% of the cases in autopsy studies. However, clinically significant metastases are rare. Small bowel perforation secondary to metastatic non-small cell lung cancer is a very rare clinical entity. The aim of this study is to describe a case of ileal perforation in a patient with intestinal metastases of a non-small cell lung cancer, along with a review of the literature. A 57-year-old male with a history of non-small cell lung cancer was referred to our emergency department with signs and symptoms of acute surgical abdomen. A computed tomography scan demonstrated dilated small bowel loops, liver deposits, and signs of perforation of an intra-abdominal hollow viscus. Emergency exploratory laparotomy revealed diffuse purulent peritonitis and a perforated ileal tumor. A segmental small bowel resection and primary anastomosis were performed. Histological and immunohistochemical findings were consistent with a metastatic non-small cell lung carcinoma. Additional evaluation revealed widespread metastatic disease. Unfortunately, despite adjuvant treatment, the patient died of progressive disease 2 months after surgery. Small bowel perforation due to metastatic non-small cell lung cancer is a very rare clinical entity. The possibility of small bowel metastases should be kept in mind in patients with lung cancer presenting with an acute abdomen. Intestinal perforation occurs in advanced stages and is usually a sign of widespread disease. Aggressive surgery can provide effective palliation and may improve short-term survival. The prognosis is however dismal.

The pathogenesis and progression of lung cancer is a complicated process in which many genes take part. But molecular gene testing is typically only performed in advanced-stage non-squamous non-small-cell lung cancer (NSCLC). The value of tyrosine kinase inhibitors (TKI) administration is not widely recognized with respect to early-stage NSCLC. Here, we present a case of a man, heavy smoker who initially presented with stage IA lung adenocarcinoma (LADC). Three years after a lung lobectomy, he was diagnosed with advanced lung squamous cell carcinoma (SCC), according to laboratory, imaging, and pathological examinations. The case initially had an early-stage LADC with an L858R epidermal growth factor receptor (EGFR) mutation. A subsequent advanced SCC bearing EGFR L858R/T790M mutations occurred 3 years after surgery. The comprehensive therapy we utilized, including surgical resection for the early-stage lesion and GP chemotherapy and local radiotherapy as the first line therapy along with gefitinib maintenance treatment for the advanced metachronous second primary tumors (MST). The synthetical therapy, have resulted in our patient with remaining alive and progression free for 4.5 years. This case suggests that changes in molecular pathology should be monitored closely throughout cancer progression to guide personalized therapy and improve prognosis. We further review administration of TKI to early-stage NSCLC and to the metachronous second primary tumors (MST) in survivors.

Atelectasis was reported as a favorable prognostic sign of pulmonary carcinoma; however, the underlying mechanism in those patients is not known. In this study, we aimed to investigate prospectively the potential impact of atelectasis and/or obstructive pneumonitis (AO) on survival and the relation between atelectasis and some laboratory blood parameters. The study was conducted on 87 advanced stage non-small cell lung cancer (NSCLC) patients. Clinical and laboratory parameters of patients at first presentation were recorded, and patients were divided into two groups according to the presence of AO in thorax computed tomography (CT). Survival was calculated using Kaplan-Meier and univariate Cox's regression analyses. Laboratory parameters that might be related with prolonged survival in atelectasis were compared using chi-square, Student's t, and Mann-Whitney U tests. Of the patients, 54% had stage IV disease, and AO was detected in 48.3% of all cases. Overall median survival was 13.2 months for all cases, 10.9 months for patients without AO, and 13.9 months for patients with AO (P=0.067). Survival was significantly longer in stage III patients with AO (14.5 months versus 9.2 months, P=0.032), but not in stage IV patients. Patients with AO in stage III had significantly lower platelet counts (P=0.032) and blood sedimentation rates than did those with no AO (P=0.045). We concluded that atelectasis and/or obstructive pneumonitis was associated with prolonged survival in locally advanced NSCLC. There was also a clear association between atelectasis and/or obstructive pneumonitis and platelets and blood sedimentation rate.

It has been recognized that patients with non-small cell lung cancer who are lifelong never-smokers constitute a distinct clinical entity. The aim of this study was to assess clinical risk factors for survival among never-smokers with non-small cell lung cancer. All consecutive non-small cell lung cancer patients diagnosed (n = 285) between May 2005 and May 2009 were included. The clinical characteristics of never-smokers and ever-smokers (former and current) were compared using chi-squared or Student's t tests. Survival curves were calculated using the Kaplan-Meier method, and log-rank tests were used for survival comparisons. A Cox proportional hazards regression analysis was evaluated by adjusting for age (continuous variable), gender (female vs. male), smoking status (never- vs. ever-smoker), the Karnofsky Performance Status Scale (continuous variable), histological type (adenocarcinoma vs. non-adenocarcinoma), AJCC staging (early vs. advanced staging), and treatment (chemotherapy and/or radiotherapy vs. the best treatment support). Of the 285 non-small cell lung cancer patients, 56 patients were never-smokers. Univariate analyses indicated that the never-smoker patients were more likely to be female (68% vs. 32%) and have adenocarcinoma (70% vs. 51%). Overall median survival was 15.7 months (95% CI: 13.2 to 18.2). The never-smoker patients had a better survival rate than their counterpart, the ever-smokers. Never-smoker status, higher Karnofsky Performance Status, early staging, and treatment were independent and favorable prognostic factors for survival after adjusting for age, gender, and adenocarcinoma in multivariate analysis. Epidemiological differences exist between never- and ever-smokers with lung cancer. Overall survival among never-smokers was found to be higher and independent of gender and histological type.

Current paradigms hold that lung carcinomas arise from pleuripotent stem cells capable of differentiation into one or several histological types. These paradigms suggest lung tumor cell ontogeny is determined by consequences of gene expression that recapitulate events important in embryonic lung development. Using oligonucleotide microarrays, we acquired gene profiles from 32 microdissected non-small-cell lung tumors. We determined the 100 top-ranked marker genes for adenocarcinoma, squamous cell, large cell, and carcinoid using nearest neighbor analysis. Results were validated by immunostaining for 11 selected proteins using a tissue microarray representing 80 tumors. Gene expression data of lung development were accessed from a publicly available dataset generated with the murine Mu11k genome microarray. Self-organized mapping identified two temporally distinct clusters of murine orthologues. Supervised clustering of lung development data showed large-cell carcinoma gene orthologues were in a cluster expressed in pseudoglandular and canalicular stages whereas adenocarcinoma homologues were predominantly in a cluster expressed later in the terminal sac and alveolar stages of murine lung development. Representative large-cell genes (E2F3, MYBL2, HDAC2, CDK4, PCNA) are expressed in the nucleus and are associated with cell cycle and proliferation. In contrast, adenocarcinoma genes are associated with lung-specific transcription pathways (SFTPB, TTF-1), cell adhesion, and signal transduction. In sum, non-small-cell lung tumors histology gene profiles suggest mechanisms relevant to ontogeny and clinical course. Adenocarcinoma genes are associated with differentiation and glandular formation whereas large-cell genes are associated with proliferation and differentiation arrest. The identification of developmentally regulated pathways active in tumorigenesis provides insights into lung carcinogenesis and suggests early steps may differ according to the eventual tumor

Lung cancer is the most commonly diagnosed and death-related cancer type and is more frequent in males. Non-small-cell lung cancer (NSCLC) accounts for about 85% of all case. In this study, it was aimed to research the relationship between advanced lung inflammation index (ALI) and the primary mass maximum standardized uptake value (SUVmax) and C-reactive protein (CRP) at initial diagnosis and the prognostic value of ALI in determining the survival in metastatic NSCLC. A total of 112 patients diagnosed as stage 4 non-small-lung cancer in our hospital between January 2006 and December 2013 were included in this study. ALI was calculated as body mass index (BMI) × serum albumin/neutrophil-to-lymphocyte ratio (NLR). The patients were divided into two groups as ALI < 18 (high inflammation) and ALI ≥ 18 (low inflammation). The log-rank test and Cox proportional hazard model were used to identify predictors of mortality. Evaluation was made of 94 male and 18 female patients with a mean age of 59.7 ± 9.9 years. A statistically significant negative relationship was determined between ALI and CRP values (P < .001), but no relationship was found between ALI and SUVmax values (P = .436). The median survival time in patients with ALI < 18 was 12 months and, in those with ALI ≥ 18, it was 16 months (P = .095). ALI is an easily calculated indicator of inflammation in lung cancer patients. Values <18 can be considered to predict a poor prognosis. © 2018 John Wiley & Sons Ltd.

Purpose Despite improvements in chemoradiation, local control remains a major clinical problem in locally advanced non-small cell lung cancer. The Hedgehog pathway has been implicated in tumor recurrence by promoting survival of tumorigenic precursors and through effects on tumor-associated stroma. Whether Hedgehog inhibition can affect radiation efficacy in vivo has not been reported. Methods and Materials We evaluated the effects of a targeted Hedgehog inhibitor (HhAntag) and radiation on clonogenic survival of human non-small cell lung cancer lines in vitro. Using an A549 cell line xenograft model, we examined tumor growth, proliferation, apoptosis, and gene expression changes after concomitant HhAntag and radiation. In a transgenic mouse model of KrasG12D-induced and Twist1-induced lung adenocarcinoma, we assessed tumor response to radiation and HhAntag by serial micro-computed tomography (CT) scanning. Results In 4 human lung cancer lines in vitro, HhAntag showed little or no effect on radio-sensitivity. By contrast, in both the human tumor xenograft and murine inducible transgenic models, HhAntag enhanced radiation efficacy and delayed tumor growth. By use of the human xenograft model to differentiate tumor and stromal effects, mouse stromal cells, but not human tumor cells, showed significant and consistent downregulation of Hedgehog pathway gene expression. This was associated with increased tumor cell apoptosis. Conclusions Targeted Hedgehog pathway inhibition can increase in vivo radiation efficacy in lung cancer preclinical models. This effect is associated with pathway suppression in tumor-associated stroma. These data support clinical testing of Hedgehog inhibitors as a component of multimodality therapy for locally advanced non-small cell lung cancer. PMID:23182391

Pulmonary atelectasis and survival in advanced non-small cell lung carcinoma

PubMed Central

2010-01-01

Atelectasis was reported as a favorable prognostic sign of pulmonary carcinoma; however, the underlying mechanism in those patients is not known. In this study, we aimed to investigate prospectively the potential impact of atelectasis and/or obstructive pneumonitis (AO) on survival and the relation between atelectasis and some laboratory blood parameters. The study was conducted on 87 advanced stage non-small cell lung cancer (NSCLC) patients. Clinical and laboratory parameters of patients at first presentation were recorded, and patients were divided into two groups according to the presence of AO in thorax computed tomography (CT). Survival was calculated using Kaplan-Meier and univariate Cox's regression analyses. Laboratory parameters that might be related with prolonged survival in atelectasis were compared using chi-square, Student's t, and Mann-Whitney U tests. Of the patients, 54% had stage IV disease, and AO was detected in 48.3% of all cases. Overall median survival was 13.2 months for all cases, 10.9 months for patients without AO, and 13.9 months for patients with AO (P = 0.067). Survival was significantly longer in stage III patients with AO (14.5 months versus 9.2 months, P = 0.032), but not in stage IV patients. Patients with AO in stage III had significantly lower platelet counts (P = 0.032) and blood sedimentation rates than did those with no AO (P = 0.045). We concluded that atelectasis and/or obstructive pneumonitis was associated with prolonged survival in locally advanced NSCLC. There was also a clear association between atelectasis and/or obstructive pneumonitis and platelets and blood sedimentation rate. PMID:20636252

OBJECTIVE: Non-small cell lung carcinoma (NSCLC) is the most common type of lung cancer. Most patients are diagnosed at an advanced stage, palliative chemotherapy therefore being the only treatment option. This study was aimed at evaluating the health-related quality of life (HRQoL) of advanced-stage NSCLC patients receiving palliative chemotherapy with carboplatin and paclitaxel. METHODS: This was a multiple case study of advanced-stage NSCLC outpatients receiving chemotherapy at a public hospital in Rio de Janeiro, Brazil. The European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire was used in conjunction with its supplemental lung cancer-specific module in order to assess HRQoL. RESULTS: Physical and cognitive functioning scale scores differed significantly among chemotherapy cycles, indicating improved and worsened HRQoL, respectively. The differences regarding the scores for pain, loss of appetite, chest pain, and arm/shoulder pain indicated improved HRQoL. CONCLUSIONS: Chemotherapy was found to improve certain aspects of HRQoL in patients with advanced-stage NSCLC. PMID:25972967

Lung cancer accounts for the majority of cancer-related deaths worldwide. At present, platinum-based therapy represents the standard of care in fit stage II and IIIA non-small cell lung cancer (NSCLC) patients following surgical resection. In advanced disease, personalized chemotherapy and targeted biologic therapy based on histological and molecular tumor profiling have already shown promise in terms of optimizing treatment efficacy. While disease stage is associated with outcome and is commonly used to determine adjuvant treatment eligibility, it is known that a subset of patients with early stage disease experience shorter survival than others with the same clinicopathological characteristics. Improved methods for identifying these individuals, at or near the time of initial diagnosis, may inform the decision to pursue adjuvant therapy options. Among the numerous candidate molecular biomarkers, only few gene-expression profiling signatures provide clinically relevant information, while real-time quantitative polymerase-chain reaction (RT-qPCR) strategy involving relatively small numbers of genes offers a practical alternative with high cross-platform performance. mRNA and/or protein expression levels of excision repair cross-complementation group 1 (ERCC1), ribonucleotide reductase M subunit 1 (RRM1) and breast cancer susceptibility gene 1 (BRCA1) are among the most promising potential biomarkers for early disease and their clinical utility is currently being evaluated in randomized phase II and III clinical trials. This review describes the most promising clinicopathological and molecular biomarkers with predictive and prognostic significance in lung cancer that have been identified through advanced research and which could influence adjuvant and neoadjuvant chemotherapy decisions for operable NSCLC in routine clinical practice.

Accurate pathologic nodal staging improves early-stage non-small-cell lung cancer survival. In an ongoing implementation study, we measured the impact of a surgical lymph node specimen collection kit and a more thorough pathologic gross dissection method, on attainment of guideline-recommended pathologic nodal staging quality. We prospectively collected data on curative-intent non-small cell lung cancer resections from 2009-2016 from 11 hospitals in 4 contiguous Dartmouth Hospital Referral Regions. We categorized patients into 4 groups based on exposure to the two interventions in our staggered implementation study design. We used Chi-squared tests to examine the differences in demographic and disease characteristics and surgical quality criteria across implementation groups. Of 2,469 patients, 1,615 (65%) received neither intervention; 167 (7%) received only the pathology intervention; 264 (11%) received only the surgery intervention; 423 (17%) had both. Rates of non-examination of lymph nodes reduced sequentially in the order of no intervention, novel dissection, kit, and combined interventions, including non-examination of: any lymph nodes, hilar/intrapulmonary and mediastinal nodes (p<0.001 for all comparisons). The rates of attainment of National Comprehensive Cancer Network, Commission on Cancer, American Joint Committee on Cancer, and American College of Surgeons Oncology Group guidelines increased significantly in the same sequential order (p<0.001 for all comparisons). The combined effect of two interventions to improve pathologic lymph node examination has a greater effect on attainment of a range of surgical quality criteria than either intervention alone.

Purpose To evaluate the treatment results in early stage non-small cell lung cancer patients who have undergone fiducial-less CyberKnife radiosurgery (CKRS). Materials and Methods From June 2011 to November 2013, 58 patients underwent CKRS at Asan Medical Center for stage I lung cancer. After excluding 14 patients, we retrospectively reviewed the records of the remaining 44 patients. All analyses were performed using SPSS ver. 21. Results The median age at diagnosis was 75 years. Most patients had inoperable primary lung cancer with a poor pulmonary function test with comorbidity or old age. The clinical stage was IA in 30 patients (68.2%), IB in 14 (31.8%). The mean tumor size was 2.6 cm (range, 1.2 to 4.8 cm), and the tumor was smaller than 2 cm in 12 patients (27.3%). The radiation dose given was 48-60 Gy in 3-4 fractions. In a median follow-up of 23.1 months, local recurrence occurred in three patients (2-year local recurrence-free survival rate, 90.4%) and distant metastasis occurred in 13 patients. All patients tolerated the radiosurgery well, only two patients developing grade 3 dyspnea. The most common complications were radiation-induced fibrosis and pneumonitis. Eight patients died due to cancer progression. Conclusion The results showed that fiducial-less CKRS shows comparable local tumor control and survival rates to those of LINAC-based SABR or CKRS with a fiducial marker. Thus, fiducial-less CKRS using Xsight lung tracking system can be effectively and safely performed for patients with medically inoperable stage I non-small cell lung cancer without any risk of procedure-related complication.

Clinical potential of nintedanib for the second-line treatment of advanced non-small-cell lung cancer: current evidence.

The therapeutic landscape in non-small-cell lung cancer (NSCLC) is changing. The description of molecular alterations leading to NSCLC carcinogenesis and progression (so-called oncogenic driver mutations) and the development of targeted agents interfering with the tumor-promoting intracellular signaling pathways have improved the outcome for many patients with advanced/metastatic NSCLC. However, many patients with stage IV NSCLC do not have one of the targetable predictive biomarkers, and are therefore in need of classical chemotherapy. This especially applies to squamous cell cancer. A platinum-based doublet chemotherapy is the standard of care for patients with stage IV NSCLC. As second-line therapies, docetaxel, pemetrexed, and the EGFR tyrosine-kinase inhibitor erlotinib have demonstrated benefit in Phase III randomized trials. Recently, the addition of the angiokinase inhibitor nintedanib to docetaxel has proven efficacious, and is a new treatment option in the second-line setting. Preclinical and clinical data of nintedanib for the treatment of lung cancer patients are reviewed here.

To assess the feasibility of proton beam therapy for the patients with locally advanced non-small lung cancer. The dosimetry was analyzed retrospectively to calculate the doses to organs at risk, such as the lung, heart, esophagus and spinal cord. A dosimetric comparison between proton beam therapy and dummy photon radiotherapy (three-dimensional conformal radiotherapy) plans was performed. Dummy intensity-modulated radiotherapy plans were also generated for the patients for whom curative three-dimensional conformal radiotherapy plans could not be generated. Overall, 33 patients with stage III non-small cell lung cancer were treated with proton beam therapy between December 2011 and August 2014. The median age of the eligible patients was 67 years (range: 44-87 years). All the patients were treated with chemotherapy consisting of cisplatin/vinorelbine or carboplatin. The median prescribed dose was 60 GyE (range: 60-66 GyE). The mean normal lung V20 GyE was 23.6% (range: 14.9-32%), and the mean normal lung dose was 11.9 GyE (range: 6.0-19 GyE). The mean esophageal V50 GyE was 25.5% (range: 0.01-63.6%), the mean heart V40 GyE was 13.4% (range: 1.4-29.3%) and the mean maximum spinal cord dose was 40.7 GyE (range: 22.9-48 GyE). Based on dummy three-dimensional conformal radiotherapy planning, 12 patients were regarded as not being suitable for radical thoracic three-dimensional conformal radiotherapy. All the dose parameters of proton beam therapy, except for the esophageal dose, were lower than those for the dummy three-dimensional conformal radiotherapy plans. In comparison to the intensity-modulated radiotherapy plan, proton beam therapy also achieved dose reduction in the normal lung. None of the patients experienced grade 4 or worse non-hematological toxicities. Proton beam therapy for patients with stage III non-small cell lung cancer was feasible and was superior to three-dimensional conformal radiotherapy for several dosimetric parameters. © The Author 2016

Adjuvant therapy in early-stage non-small cell lung cancer.

Evidence clearly supports adjuvant chemotherapy following resection in patients with stage II or III non-small cell lung cancer (NSCLC). Based on 3 landmark studies, adjuvant chemotherapy has become standard in completely resected NSCLC stage II and IIIA. Survival benefit from adjuvant chemotherapy is estimated to be between 3% and 15%, depending on stage. Treatment should include 4 cycles of platinum-based combination chemotherapy. There is uncertainty about chemotherapy prescription in those patients with resected stage IB NSCLC, as the risk of recurrence is lower in early NSCLC and the magnitude of benefit of adjuvant therapy is proportional to the risk of relapse according to stage. Postoperative radiotherapy (PORT) should not be used for stage I or II NSCLC, and remains controversial in resected stage IIIA (N2) disease. All positive adjuvant trials have utilized a cisplatin-based regimen, usually in combination with vinorelbine, and this should be considered the standard approach. Prognostic factors to select patients who will benefit from adjuvant therapy in general or from platinum-based chemotherapy are under discussion, but not yet established. In future we hope to optimize treatment convenience for the patients by using other combinations with the hope of better efficacy results. Work is currently under way to identify prognostic factors which in future may help to identify patients who are most likely to benefit from chemotherapy. Copyright 2010 S. Karger AG, Basel.

The recurrence rate for stage I non-small cell lung cancer is high, with 20-40% of patients that relapse after surgery. The aim of this study was to evaluate new F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) derived parameters, such as standardized uptake value index (SUVindex), metabolic tumor volume (MTV) and total lesion glycolysis (TLG), as predictive factors for recurrence in resected stage I non-small cell lung cancer. We retrospectively reviewed 99 resected stage I non-small cell lung cancer patients that were grouped by SUVindex, TLG and MTV above or below their median value. Disease free survival was evaluated as primary end point. The 5-year overall survival and the 5-year disease free survival rates were 62% and 73%, respectively. The median SUVindex, MTL and TLG were 2.73, 2.95 and 9.61, respectively. Patients with low SUVindex, MTV and TLG were more likely to have smaller tumors (p ≤ 0.001). Univariate analysis demonstrated that SUVindex (p = 0.027), MTV (p = 0.014) and TLG (p = 0.006) were significantly related to recurrence showing a better predictive performance than SUVmax (p = 0.031). The 5-year disease free survival rates in patients with low and high SUVindex, MTV and TLG were 84% and 59%, 86% and 62% and 88% and 60%, respectively. The multivariate analysis showed that only TLG was an independent prognostic factor (p = 0.014) with a hazard ratio of 4.782. Of the three PET-derived parameters evaluated, TLG seems to be the most accurate in stratifying surgically treated stage I non-small cell lung cancer patients according to their risk of recurrence.

Despite its extensive size, variations in the clinicopathologic features of tumors in the lower lobe have been little studied. The present study investigated the prognostic differences in tumors originating from the superior and basal segments of the lower lobe in patients with non-small cell lung cancer. Data of 134 patients who underwent lobectomy or segmentectomy with systematic nodal dissection for clinical stage I, radiologically solid-dominant, non-small cell lung cancer in the superior segment (n = 60) or basal segment (n = 74) between April 2007 and December 2015 were retrospectively reviewed. Factors affecting survival were assessed by the Kaplan-Meier method and Cox regression analyses. Prognosis in the superior segment group was worse than that in the basal segment group (5-year overall survival rates 62.6% versus 89.9%, p = 0.0072; and 5-year recurrence-free survival rates 54.4% versus 75.7%, p = 0.032). In multivariable Cox regression analysis, a superior segment tumor was an independent factor for poor overall survival (hazard ratio 3.33, 95% confidence interval: 1.22 to 13.5, p = 0.010) and recurrence-free survival (hazard ratio 2.90, 95% confidence interval: 1.20 to 7.00, p = 0.008). The superior segment group tended to have more pathologic mediastinal lymph node metastases than the basal segment group (15.0% versus 5.4%, p = 0.080). Tumor location was a prognostic factor for clinical stage I non-small cell lung cancer in the lower lobe. Patients with superior segment tumors had worse prognosis than patients with basal segment tumors, with more metastases in mediastinal lymph nodes. Copyright © 2017 The Society of Thoracic Surgeons.

Role of Chemotherapy and Targeted Therapy in Early-Stage Non-Small Cell Lung Cancer.

PubMed

Gadgeel, Shirish M

2017-01-01

On the basis of several randomized trials and meta-analyses, adjuvant chemotherapy is the accepted standard of care for certain patients with early-stage non-small cell lung cancer (NSCLC). Patients with stage II, IIIA, or large (≥ 4 cm) IB tumors are candidates for adjuvant chemotherapy. The survival improvement with adjuvant chemotherapy is approximately 5% at 5 years, though certain trials have suggested that it can be 8% to 10%. Neoadjuvant chemotherapy also has shown a survival advantage, though the volume of data with this approach is far less than that of adjuvant chemotherapy. The combination of cisplatin and vinorelbine is the most well-studied regimen, but current consensus is to use four cycles of any of the platinum-based chemotherapy regimens commonly used as front-line therapy for patients with advanced-stage NSCLC. Trials to define biomarkers that can predict benefit from adjuvant chemotherapy have not been successful, but results of other such trials are still awaited. On the basis of the benefit observed with targeted agents in patients with advanced-stage disease and driver genetic alterations in their tumors, ongoing trials are evaluating the utility of these targeted agents as adjuvant therapy. Similarly, clinical benefit observed with checkpoint inhibitors has prompted assessment of these drugs in patients with early-stage NSCLC. It is very likely, in the future, that factors other than the anatomy of the tumor will be used to select patients with early-stage NSCLC for systemic therapy and that the choice of systemic therapy will extend beyond platinum-based chemotherapy.

We report a 66-year-old Japanese male with end-stage renal disease (ESRD) and advanced non-small cell lung cancer (NSCLC) who was on hemodialysis. The patient harbored high programmed death ligand 1 (PD-L1) expression and was successfully treated with pembrolizumab. Laboratory examination upon diagnosis showed elevated serum creatinine (6.58 mg/dL). We administered pembrolizumab (200 mg/body) and repeated every 3 weeks. His renal dysfunction gradually progressed, hemodialysis was initiated after eight courses of pembrolizumab, and the antitumor effect was maintained at five months after hemodialysis initiation. Therefore, pembrolizumab can be administered for patients with ESRD and advanced NSCLC, who harbor high PD-L1 expression, during preparation for hemodialysis.

Introduction Guidelines recommend that patients with clinical stage IIIA non-small cell lung cancer (NSCLC) undergo histologic confirmation of pathologic lymph nodes. Studies have suggested that invasive mediastinal staging is underutilized, though practice patterns have not been rigorously evaluated. Methods We used the Surveillance, Epidemiology, and End Results-Medicare database to identify patients with stage IIIA NSCLC diagnosed from 1998 through 2005. Invasive staging and use of positron emission tomography (PET) scanning were assessed using Medicare claims. Multivariable logistic regression was used to identify patient characteristics associated with use of invasive staging. Results Of 7583 stage IIIA NSCLC patients, 1678 (22%) underwent invasive staging. Patients who received curative intent cancer treatment were more likely to undergo invasive staging than patients who did not receive cancer specific therapy (30% vs. 9.8%, adjusted odds ratio [OR} 3.31, 95% CI 2.78–3.95). The oldest patients (age 85–94) were less likely to receive invasive staging than the youngest ((age 67–69) (27.6 % vs. 11.9%, OR 0.46, 95% CI 0.34–0.61)). Sex, marital status, income and race were not associated with the use of the invasive staging. The use of invasive staging was stable throughout the study period, despite an increase in the use of PET scanning from less than 10% of patients prior to 2000 to almost 70% in 2005. Conclusion Nearly 80% of Medicare beneficiaries with stage IIIA NSCLC do not receive guideline adherent mediastinal staging; this failure cannot be entirely explained by patient factors or a reliance on PET imaging. Incentives to encourage use of invasive staging may improve care. PMID:22134069

To evaluate the efficacy and safety of icotinib hydrochloride in the treatment of patients with advanced non-small cell lung cancer (NSCLC) and discuss the influence factors on efficacy. 120 treatment-experienced patients confirmed by pathology or cytology with stage III B-IV non-small cell lung cancer took icotinib hydrochloride and erlotinib orally until the occurrence of disease progression or serious adverse reactions. Then, the efficacy of icotinib hydrochloride and the related influence factors were analyzed. In icotinib hydrochloride group, the response rate and the disease control rate were 30.00% and 65.00%, and the median progression-free survival time was 179 days (95% CI: 103.21-254.78); in erlotinib group, the response rate and the disease control rate were 25.00% and 56.70%, and the median progression-free survival time was 121 days (95% CI: 95.05-146.94). Moreover, the objective response rate and the disease control rate of second-line therapy were both superior to the third-line and above therapy. The objective response rate of patients with complete response/partial response/stable disease after the first-line therapy was higher than that of patients without response after the first-line therapy (p<0.05), and the significant differences existed in the objective response rate and the disease control rate among mutant group, wild-type group, and unknown group (p<0.05). The response rate and the disease control rate of erythra group were higher than those of non-erythra group (p<0.05). It was showed in the univariate analysis that the progression-free survival was correlated with the smoking status and the epidermal growth factor receptor gene mutations. The icotinib hydrochloride is effective and safe in treating the treatment-experienced patients with advanced NSCLC, especially for patients with sensitive mutations.

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. 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. 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. Icotinib hydrochloride is effective especially in EGFR mutation carriers and well tolerated in patients with recurrent advanced non-small-cell lung cancer.

Altered expression of MUC4 plays an oncogenic role in various cancers, including pancreatic, ovarian, and breast. This study evaluates the expression and role of MUC4 in non-small-cell lung cancer (NSCLC). We used a paired system of MUC4-expressing (H292) and MUC4-nonexpressing (A549) NSCLC cell lines to analyze MUC4-dependent changes in growth rate, migration, and invasion using these sublines. We also evaluated the alterations of several tumor suppressor, proliferation, and metastasis markers with altered MUC4 expression. Furthermore, the association of MUC4 expression (by immunohistochemistry) in lung cancer samples with patient survival was evaluated. MUC4-expressing lung cancer cells demonstrated a less proliferative and metastatic phenotype. Up-regulation of p53 in MUC4-expressing lung cancer cells led to the accumulation of cells at the G2/M phase of cell cycle progression. MUC4 expression attenuated Akt activation and decreased the expression of Cyclins D1 and E, but increased the expression of p21 and p27. MUC4 expression abrogated cancer cell migration and invasion by altering N- & E-cadherin expression and FAK phosphorylation. A decrease in MUC4 expression was observed with increasing tumor stage (mean composite score: stage I, 2.4; stage II, 1.8; stage III, 1.4; and metastatic, 1.2; p = 0.0093). Maximal MUC4 expression was associated with a better overall survival (p = 0.042). MUC4 plays a tumor-suppressor role in NSCLC by altering p53 expression in NSCLC. Decrease in MUC4 expression in advanced tumor stages also seems to confirm the novel protective function of MUC4 in NSCLC.

The role of surgical lung resection following neo-adjuvant radio-chemotherapy (RCT) in patients with locally advanced non-small cell lung cancer (NSCLC) is yet not clearly defined. The aim of our study was to analyze the postoperative survival and to identify relevant prognostic factors. 46 patients underwent curative resections after neo-adjuvant RCT for locally advanced NSCLC (IIIA/IIIB) between February 2008 and February 2015. A retrospective data analysis regarding preoperative regression status, perioperative mortality, postoperative survival, patho-histological remission, relapse pattern and other prognostic factors was performed. A neo-adjuvant RCT with a median radiation dose of 50.4 [range, 45-60] Gy was performed in 44 (96 %) patients. Partial and/or complete regression was observed in 32 (70 %) patients. R0-resection was achieved in 44 (96 %) patients. The 30-day mortality was 4 % and the perioperative morbidity was 37 %. The overall and progression free 5-year survival rate was 47 % and respectively 45 % [in median 58 months]. The 5-year survival rate of 64 % in the "responder"-group was significantly better when compared with 24 % in the "non-responder"-group (p = 0.038). The tri-modality therapy improved the prognosis in patients with locally advanced NSCLC (stage IIIA/IIIB). The complete patho-histological remission is an important prognostic factor for better long term survival. Dividing the patients in "responder" and "non-responder" after neo-adjuvant RCT may have large therapeutically consequences in the future. Georg Thieme Verlag KG Stuttgart · New York.

The outcomes of so called "salvage" resections after definitive chemoradiation vs. curative resections after neoadjuvant chemoradiation therapy (IT-resection) in patients with stage IIIA/B locally advanced non-small cell lung cancer have rarely been compared. The aim of our study was to compare perioperative results, postoperative and recurrence-free survival and to identify relevant prognostic survival factors for both therapy strategies. Between June 2008 and May 2017, 43 patients underwent pulmonary resection following induction therapy (group 1) and 14 patients underwent salvage resection after definitive chemoradiation (group 2). Retrospective analysis was performed of demographic factors, tumour stage and location, initial therapy, preoperative regression status, perioperative morbidity and mortality, postoperative and recurrence-free survival. In group 2, significantly higher radiation dose was applied (p < 0.001) and the interval between chemoradiation and lung resection was significantly longer (p = 0.02). In addition, significantly higher perioperative blood loss and more frequent blood transfusions were noted (p = 0.003 and 0.005, respectively). Perioperative morbidity and mortality were statistically comparable in the two groups (p = 0.72 and 0.395, respectively). Postoperative 5 year survival in group 1 was 55%, in group 2 48% (log-rank p = 0.353). Five year recurrence-free survival in group 1 was 53%, in group 2 42% (log-rank p = 0.180). Diffuse metastasis occurred mostly in group 2, whereas in group 1 oligometastasis was more frequently noted. Postoperative outcome after salvage resection seems statistically comparable to results following curative resection after induction therapy. Diffuse distant metastasis is frequently noted. Careful patient selection is required. Georg Thieme Verlag KG Stuttgart · New York.

To evaluate the efficacy and safety of icotinib hydrochloride in patients with advanced non-small cell lung cancer (NSCLC). A total of 89 patients with stage IIIB or IV NSCLC received icotinib at a dose of 125 mg administered 3 times a day. Icotinib treatment was continued until disease progression or development of unacceptable toxicity. A total of 89 patients were assessable. In patients treated with icotinib, the overall response rate (RR) was 36.0% (32/89), and the disease control rate (DCR) was 69.7% (62/89). RR and DCR were significantly improved in patients with adenocarcinoma versus non-adenocarcinoma (P<0.05). The symptom improvement rate was 57.3% (51/89), and the main symptoms improved were cough, pain, chest distress, dyspnea, and Eastern Cooperative Oncology Group performance status. The main toxic effects were rash [30/89 (33.7%)] and diarrhea [15/89 (16.9%)]. The level of toxicity was typically low. The use of icotinib hydrochloride in the treatment of advanced NSCLC is efficacious and safe, and its toxic effects are tolerable.

Maintenance or non-maintenance therapy in the treatment of advanced non-small cell lung cancer: that is the question.

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. Copyright © 2010 Elsevier Ltd. All rights reserved.

The PD-L1 antibody atezolizumab has shown promising efficacy in patients with advanced non-small cell lung cancer. But the predictive marker of clinical benefit has not been identified. This study aimed to search for potential predictive factors in circulating blood of patients receiving atezolizumab. Ten patients diagnosed with advanced non-small cell lung cancer were enrolled in this open-label observing study. Circulating immune cells and plasma tumor markers were examined in peripheral blood from these patients before and after atezolizumab treatment respectively. Relation between changes in circulating factors and anti-tumor efficacy were analyzed. Blood routine test showed that atezolizumab therapy induced slightly elevation of white blood cells count generally. The lymphocyte ratio was increased slightly in disease controlled patients but decreased prominently in disease progressed patients in response to atezolizumab therapy. Flow cytometric analysis revealed changes in percentage of various immune cell types, including CD4+ T cell, CD8+ T cell, myeloid-derived suppressor cell, regulatory T cell and PD-1 expressing T cell after atezolizumab. Levels of plasma tumor marker CEA, CA125 and CA199 were also altered after anti-PD-L1 therapy. In comparison with baseline, the disease progressed patients showed sharp increase in tumor marker levels, while those disease controlled patients were seen with decreased regulatory T cell and myeloid-derived suppressor cell ratios. The circulating immune cell ratios and plasma tumor marker levels were related with clinical efficacy of atezolizumab therapy. These factors could be potential predictive marker for anti-PD-L1 therapy in advanced non-small cell lung cancer.

Lung cancer is a common disease and the leading cause of cancer-related mortality, with non-small cell lung cancer (NSCLC) accounting for the majority of cases. Following diagnosis of lung cancer, accurate staging is essential to guide clinical management and inform prognosis. Positron emission tomography (PET) in conjunction with computed tomography (CT)—as PET-CT has developed as an important tool in the multi-disciplinary management of lung cancer. This article will review the current evidence for the role of 18F-fluorodeoxyglucose (FDG) PET-CT in NSCLC diagnosis, staging, response assessment and follow up. PMID:29666818

We reviewed our initial institutional experience with the use of stereotactic hypofractionated radiation therapy (SFRT) in patients with stage I non-small cell lung cancer (NSCLC). Thirty patients with inoperable stage I non-small cell lung cancer due to a severe chronic obstructive pulmonary disease (COPD) and/or chronic heart disease (Eastern Cooperative Oncology Group (ECOG) performance status of 0-2) were treated between December 2000 and October 2003 with SFRT in curative intent. Infiltration of locoregional lymph nodes and distant metastases were ruled out by computerized tomography (CT) scan of the brain, thorax, and abdomen, and by whole body FDG-positron emission tomography scan in all patients. Total RT doses ranged from 24.0 to 37.5 Gy, given in 3-5 fractions to the 60% isodose encompassing the planning target volume. Immobilization was carried out by a vacuum couch and a low-pressure foil. The clinical target volume was the tumor as it appeared in lung windowing on lung CT scan. Organ movements (caused by breathing; range, 6-22 mm) and reproducibility of patient positioning in the couch (range, 3-12 mm) were calculated by sequential CT and orthogonal films. The individual values were taken into account as a safety margin for the definition of the planning target volume (PTV). The median follow-up of living patients is 18 months (range, 6-38 months). As maximum response, there were 10 (33%) complete responses (CRs) and 14 (47%) partial responses (PRs), resulting in a total response rate of 80%. Stable disease was observed in 6 (20%) patients, while no patient experienced progressive disease. During follow-up, 2 (7%) local recurrences were observed (after 17 and 18 months, respectively). Of 5 (17%) patients who developed distant metastasis, 1 patient developed it in liver (3 months), another one in brain (6 months), and another one in the lung (36 months), while 2 patients developed it in mediastinal lymph nodes (after 8, and 11 months, respectively) only

Non-small cell lung cancer (NSCLC) is a leading cause of cancer deaths, and over 60% of patients present with advanced stages. Although polysaccharide peptides (PSP), isolated from the fungus Coriolus versicolor, have been reported to have anti-tumor effects, its clinical efficacy has not been properly evaluated. Double-blind placebo-controlled randomized study to evaluate the effects of 28-day administration of PSP (Windsor Pharmaceutical, Hong Kong) on patients, who had completed conventional treatment for advanced NSCLC. Thirty-four patients, with no significant difference in their baseline demographic, clinical or tumor characteristics, or previous treatment regimes (P>0.05) were recruited into each of the PSP and control arms. After 28-day treatment, there was a significant improvement in blood leukocyte and neutrophil counts, serum IgG and IgM, and percent of body fat among the PSP, but not the control, patients (P<0.05). Although the evaluable PSP patients did not improve in NSCLC-related symptoms, there were significantly less PSP patients withdrawn due to disease progression, than their control counterparts (5.9 and 23.5%, respectively; P=0.04; OR 4.00). There was no reported adverse reaction attributable to the trial medications. PSP treatment appears to be associated with slower deterioration in patients with advanced NSCLC.

Overdiagnosis among clinically detected lung cancers likely consists of cases that are non-aggressive and slowly progressive and will never disseminate, cause symptoms or be a threat to a subject's survival, even if untreated. In this study, we estimate the prevalence of non-aggressive lung cancers from a large, population-based cancer registry. We identified individuals ≥65 years with histologically confirmed, untreated stage I non-small cell lung cancers (NSCLCs) from the Surveillance, Epidemiology, and End Results-Medicare registry. We estimated the rate of non-aggressive lung cancers by determining the point at which the cumulative lung cancer-specific survival curve no longer changed (ie, the slope approaches zero). At this point, there are no additional deaths due to progressive lung cancer observed among untreated patients after adjusting for deaths from competing risks (these long-term survivors can be considered 'non-aggressive cases). The overall rate of non-aggressive cancers among 2197 clinically detected cases of untreated stage I NSCLC was 2.4%, 95% CI: 1.0% to 3.8%. The rate of non-aggressive cancer was 1.9% (95% CI: 0.0% to 4.9%) for women and 2.4% (95% CI: 0.7% to 4.1%) for men (p=0.84). When stratifying by tumour size, non-aggressive cancer rates were 10.2% (95% CI: 0.0% to 29.3%), 2.1% (95% CI: 0.0% to 9.2%), 4.9% (95% CI: 0.0% to 10.3%), 1.8% (95% CI: 0.0% to 5.2%) and 0.0% (95% CI: 0.0% to 1.0%) for tumour sizes <15 mm, 15-24 mm, 25-34 mm, 35-44 mm and ≥45 mm, respectively. In comparison with the smallest tumour sizes (<15 mm), the rates of non-aggressive cancers were not statistically significantly different for tumour sizes 15-24 mm (p=0.36), 25-34 mm (p=0.57), 35-44 mm (p=0.38) and tumour sizes >45 mm (p=0.30). We found relatively low rates of non-aggressive cancers among clinically detected, stage I NSCLC regardless of sex or size. Our findings suggest that most clinically diagnosed early stage cancers should be treated with

Icotinib hydrochloride is an orally administered small-molecule reversible tyrosine kinase inhibitor that has been independently researched and developed and has independent intellectual property rights in the People’s Republic of China. Clinical trials have demonstrated that the response to icotinib among advanced non-small-cell lung cancer (NSCLC) patients who received at least one platinum-based chemotherapy regimen was not inferior to gefitinib. Since being launched August 2011 in the People’s Republic of China, icotinib has been widely used in clinics, and has become an important treatment option for Chinese patients with advanced NSCLC. The present study presents the Phase I, II, and III clinical trials of icotinib and discusses current clinical applications in the People’s Republic of China and future research directions.

The efficacy, toxicity, and prognostic factors of high-dose proton beam therapy (PBT) for peripheral stage I non-small-cell lung cancer were assessed in this retrospective study. Fifty patients with peripheral stage I non-small-cell lung cancer, two of whom had heterochronic multiple lung cancers, underwent high-dose PBT between January 2009 and September 2014. The relative biological effectiveness of the proton beam was defined as 1.1. The beam energy and spread-out Bragg peak were fine-tuned for the 90% isodose volume of the prescribed dosage to encompass the planning target volume. The cumulative survival curves were calculated using the Kaplan-Meier method. Treatment toxicities were evaluated using version 4 of the Common Terminology Criteria for Adverse Events, version 4. The study included 35 males and 15 females with a median age of 72.5 years. The median follow-up period was 22.8 months. The clinical stage was IA in 44 (85%) and IB in eight (15%) tumors. The total dose of PBT was 66 GyE in 10 fractions in all tumors. Three-year overall survival rate among all patients was 87.9% (95% confidence interval [CI], 94.8%-73.2%). Forty-five patients were alive, and 5 were dead. Three-year local control and progression-free survival rates were 95.7% (95% CI, 98.9%-83.8%) and 76.3% (95% CI, 86.9%-59.3%), respectively. Only one patient experienced Grade 2 pneumonitis. High-dose PBT may be an effective and safe treatment option for patients with stage I non-small-cell lung cancer. Copyright © 2015 Elsevier Inc.

Circulating tumor cell (CTC) counts are an established prognostic marker in metastatic prostate, breast and colorectal cancer, and recent data suggest a similar role in late stage non-small cell lung cancer (NSCLC). However, due to sensitivity constraints in current enrichment-based CTC detection technologies, there are few published data about CTC prevalence rates and morphologic heterogeneity in early-stage NSCLC, or the correlation of CTCs with disease progression and their usability for clinical staging. We investigated CTC counts, morphology and aggregation in early stage, locally advanced and metastatic NSCLC patients by using a fluid-phase biopsy approach that identifies CTCs without relying on surface-receptor-based enrichment and presents them in sufficiently high definition (HD) to satisfy diagnostic pathology image quality requirements. HD-CTCs were analyzed in blood samples from 78 chemotherapy-naïve NSCLC patients. 73% of the total population had a positive HD-CTC count (>0 CTC in 1 mL of blood) with a median of 4.4 HD-CTCs mL-1 (range 0-515.6) and a mean of 44.7 (±95.2) HD-CTCs mL-1. No significant difference in the medians of HD-CTC counts was detected between stage IV (n = 31, range 0-178.2), stage III (n = 34, range 0-515.6) and stages I/II (n = 13, range 0-442.3). Furthermore, HD-CTCs exhibited a uniformity in terms of molecular and physical characteristics such as fluorescent cytokeratin intensity, nuclear size, frequency of apoptosis and aggregate formation across the spectrum of staging. Our results demonstrate that despite stringent morphologic inclusion criteria for the definition of HD-CTCs, the HD-CTC assay shows high sensitivity in the detection and characterization of both early- and late-stage lung cancer CTCs. Extensive studies are warranted to investigate the prognostic value of CTC profiling in early-stage lung cancer. This finding has implications for the design of extensive studies examining screening, therapy and surveillance in

Meta-analysis is a statistical method allowing an evaluation of the direction and quantitative importance of a treatment effect observed in randomized trials which have tested the treatment but have not provided a definitive conclusion. In the present review, we discuss the methodology and the contribution of meta-analyses to the treatment of advanced-stage or metastatic non-small-cell lung cancer. In this area of cancerology, meta-analyses have provided determining information demonstrating the impact of chemotherapy on patient survival. They have also helped define a two-drug regimen based on cisplatin as the gold standard treatment for patients with a satisfactory general status. Recently, the meta-analysis method was used to measure the influence of gemcitabin in combination with platinium salts and demonstrated a small but significant benefit in survival, confirming that gemcitabin remains the gold standard treatment in combination with cisplatin.

Radiation pneumonitis is the most frequent acute pulmonary toxicity following stereotactic body radiation therapy for lung cancer. Here, we investigate clinical and dosimetric factors associated with symptomatic radiation pneumonitis in patients with stage I non-small cell lung cancer treated with stereotactic body radiation therapy. A total of 67 patients with stage I non-small cell lung cancer who received stereotactic body radiation therapy at our institution were enrolled, and their clinicopathological parameters and dosimetric parameters were recorded and analyzed. The median follow-up period was 26.4 months (range: 7-48 months). In univariate analysis, tumor size ( P = .041), mean lung dose ( P = .028), V2.5 ( P = .024), V5 ( P = .014), V10 ( P = .004), V20 ( P = .024), V30 ( P = .020), V40 ( P = .040), and V50 ( P = 0.040) were associated with symptomatic radiation pneumonitis. In multivariable logistic regression analysis, V10 ( P = .049) was significantly associated with symptomatic radiation pneumonitis. In conclusion, this study found that tumor size, mean lung dose, and V2.5 to V50 were risk factors markedly associated with symptomatic radiation pneumonitis. Our data suggested that lung V10 was the most significant factor, and optimizing lung V10 may reduce the risk of symptomatic radiation pneumonitis. For both central and peripheral stage I lung cancer, rate of radiation pneumonitis ≥grade 2 was low after stereotactic body radiation therapy with appropriate fraction dose.

Treatment of lung carcinoma is multidisciplinary. There are different therapeutic strategies available, although surgery shows the best results in those patients with lung carcinoma in early stages. Other options such as stereotactic radiation therapy are relegated to patients with small tumors and poor cardiopulmonary reserve or to those who reject surgery. Adjuvant chemotherapy is not justified in patients with stage i of the disease and so double adjuvant chemotherapy should be considered. This adjuvant chemotherapy should be based on cisplatin after surgery in those patients with stages ii and IIIA. Copyright © 2012 AEC. Published by Elsevier Espana. All rights reserved.

To explore the feasibility and activity of a histology-based induction combination chemotherapy for elderly patients with clinical stage III non-small cell lung cancer (NSCLC). Patients aged ≥70 years with stage IIIA and IIIB lung squamous cell carcinoma (SCC) or adenocarcinoma were treated with three cycles of carboplatin and gemcitabine or pemetrexed, respectively, followed by definitive radiotherapy or surgery. The primary endpoint was the overall response rate (ORR) following induction. Twenty-seven patients, with a median age of 74 years (range=70-80 years) were treated for adenocarcinoma in 14 (52%) and SCC in 13 (48%), clinical stage IIIA in eight (30%) and IIIB in 19 (70%). Grade 3 or 4 toxicity was reported for five patients (18.5%). The ORR was 46% in 12 (partial responses) out of 26 assessable patients. Histology-based induction combination chemotherapy is active and feasible in elderly patients with stage III NSCLC. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

To explore the experience and meaning of hope in relation to the healing process of patients living with stage IIIb or IV non-small cell lung cancer. Interpretative qualitative study design. Peter Brojde Lung Cancer Centre in the Jewish General Hospital in Montreal, Quebec, Canada. 12 English- and French-speaking patients, aged 36-78 years. One 60-90-minute semistructured interview per participant was conducted. An inductive approach to data analysis was taken, involving immersion in the data, coding, classifying, and creating linkages. Four main themes emerged: (a) the morass of shattered hope, (b) tentative steps toward a new hope paradigm, (c) reframing hope within the context of a life-threatening illness, and (d) strengthening the link between hope and wellness. Patients described a process where hope was diminished or lost entirely, regained, and reshaped as they learned to live and grow following their diagnosis. This study adds to the literature by describing the dynamic nature of hope as well as factors facilitating or hindering the hope process. It demonstrates how finding meaning, a structural component of healing, can be used to envision a new hopeful future. This study suggests hope and healing cannot exist in isolation, and highlights the importance of understanding the fluctuating nature of hope in patients with advanced lung cancer to foster it, therefore promoting healing.

Bevacizumab is a monoclonal antibody targeting the vascular endothelial growth factor receptor and a key drug for advanced non-small cell lung cancer. There are few reports describing bevacizumab-induced chronic interstitial pneumonia. A 62-year-old man with advanced non-small cell lung cancer was admitted to our hospital with dyspnea. He previously received four courses of carboplatin plus paclitaxel with bevacizumab combination therapy and thereafter received four courses of maintenance bevacizumab monotherapy. A chest-computed tomography scan on admission revealed diffuse ground glass opacity. He had not received any other drugs and did not have pneumonia. Thus, he was diagnosed with bevacizumab-induced chronic interstitial pneumonia and was treated with a high dose of corticosteroids. After steroid treatment, his dyspnea and radiological findings improved. This case report is the first description of bevacizumab-induced chronic interstitial pneumonia during maintenance therapy in a patient with non-small cell lung cancer.

The American Society of Clinical Oncology published the goals of individualized care including advance care planning for advanced cancer patients in 2011. However, no data are available on the implementation status of advance care planning. We retrospectively reviewed the electronic medical records and informed consent forms of consecutive Stage IV non-small cell lung cancer patients treated with chemotherapy between January 2010 and December 2012 at our institution. Two outcomes were defined to investigate the advance care planning implementation status: C-D, the duration from the last day of chemotherapy to death and D-D, that from the day of confirmed do-not-attempt-resuscitation order to death. The study included 136 eligible patients. The advance care planning implementation status in participating patients was as follows: 96 (70%) patients received information on 'incurable disease before first-line chemotherapy', 69 (50%) were informed about 'supportive care before first-line chemotherapy', whereas 43 (32%) learned about their prognosis. The do-not-attempt-resuscitation decision was reflected in 29 patients' will (21%). The median C-D was 64 days. Receipt of ≤2 chemotherapy regimens and provision of prognosis information to patients were significantly associated with long C-D in multivariate analysis. The median D-D was 25 days. Provision of information on supportive care before first-line chemotherapy and provision of prognosis information to patients were significantly associated with long D-D in multivariate analysis. Our results suggest that there is possible benefit from providing information on supportive care before first-line chemotherapy and informing patients about their prognosis in prolonging the duration of supportive care. © The Author 2014.

EGFR-tyrosine kinase inhibitors play an important role in the treatment of advanced non-small cell lung cancer (NSCLC). EGFR mutations in advanced NSCLC occur in approximately 35% of Asian patients and 60% of patients with adenocarcinoma. However, the frequency and type of EGFR mutations in early-stage lung adenocarcinoma remain unclear. We retrospectively collected data on patients diagnosed with lung adenocarcinoma tested for EGFR mutation. Early stage was defined as pathological stage IA-IIIA after radical lung cancer surgery, and advanced stage was defined as clinical stage IIIB without the opportunity for curative treatment or stage IV according to the American Joint Committee on Cancer Staging Manual, 7th edition. A total of 1699 patients were enrolled in this study from May 2014 to May 2016; 750 were assigned to the early-stage and 949 to the advanced-stage group. Baseline characteristics of the two groups were balanced, except that there were more smokers in the advanced-stage group (P < 0.001). The total EGFR mutation rate in the early-stage group was similar to that in the advanced-stage group (53.6% vs. 51.4%, respectively; P = 0.379). There was no significant difference in EGFR mutation type between the two groups. In subgroup analysis of smoking history, there was no difference in EGFR mutation frequency or type between the early-stage and advanced-stage groups. Early-stage and advanced-stage groups exhibited the same EGFR mutation frequencies and types. © 2018 The Authors.

There is no standard pathological method for determining vessel invasion in lung cancer. Herein, we examine whether vessel invasion can be accurately assessed using hematoxylin-eosin staining alone, and investigate the prognostic impact of the presence and frequency of vessel invasion in lung cancer. Vessel invasion was assessed by hematoxylin-eosin, Victoria blue, and D2-40 in 251 completely resected stage I non-small cell lung cancer patients. Vessel invasion was classified into 3 grades according to the number of invaded vessels. Using hematoxylin-eosin and Victoria blue, vascular invasion was detected in 27 (10.8 %) and 75 (29.9 %) of patients, respectively. Lymphatic permeation was detected in 126 (50.2 %) and 70 (27.9 %) of patients using hematoxylin-eosin and D2-40 staining. Hematoxylin-eosin staining did not accurately detect a high frequency of vessel invasion; only 5 and 21.7 % of high-frequency vascular invasion and lymphatic permeation cases diagnosed with Victoria blue and D2-40 were detected. Multivariate analysis based on elastic stain and immunostaining indicated that plural invasion, a high frequency of vascular invasion (hazard ratio 4.00), and a high frequency of lymphatic permeation (hazard ratio 2.30) were independent predictors of cancer recurrence within 3 years. Likewise, an age ≥70 years, male, and a high frequency of vascular invasion (hazard ratio 3.41) were independent predictors of overall survival. Vascular invasion should be confirmed by elastic stains, and the frequency, not but the presence, of vascular invasion is a powerful independent prognostic factor in completely resected stage I non-small cell lung cancer patients.

To explore the efficacy and side effects of icotinib hydrochloride in the treatment of patients with advanced non-small cell lung cancer (NSCLC). The efficacy and side effects of icotinib hydrochloride in treatment of 59 cases with stage IV NSCIC and followed-up from March 2009 to January 2012 were retrospectively analyzed. Twenty seven patients (45.8%) showed partial response (PR), 17 patients (28.8%) achieved SD, and 15 (25.4%) had progressive disease. The objective response rate (ORR) was 45.8% (27/59), and disease control rate (DCR) was 74.6% (44/59). Among the 23 patients with EGFR mutation, ORR was 73.9% (17/23), and DCR was 95.7% (22/23). Thirty six patients (61.0%) achieved remission of symptoms to varying degrees. The main symptoms relieved were cough, asthmatic suffocating, pain and hoarseness. The major adverse events were mild skin rash (35.6%) and diarrhea (15.3%). Others were dry skin, nausea and stomach problems. The efficacy of icotinib hydrochloride were related to the ECOG performance status, smoking history, EGFR mutation and rash significantly (P < 0.05). Monotherapy with icotinib hydrochloride is effective and tolerable for patients with advanced NSCLC, especially with EGFR mutation.

Gefitinib in advanced non-small cell lung cancer: does it deserve a second chance?

There has been intense investigation into the epidermal growth factor receptor (EGFR) as a therapeutic target in the treatment of non-small cell lung cancer (NSCLC). Currently there are two EGFR tyrosine kinase inhibitors, erlotinib and gefitinib, approved for the treatment of advanced NSCLC. In a phase III trial (BR.21), treatment with erlotinib resulted in a statistically significant improvement in overall survival in patients who had experienced progression after one or two previous chemotherapy treatments in comparison with best supportive care (BSC). In contrast, in the Iressa Survival Evaluation in Lung Cancer (ISEL) trial, treatment with gefitinib did not result in a statistically significant improvement in overall survival time in comparison with BSC in patients who had received one or two previous chemotherapy treatments and were refractory to or intolerant of the previous chemotherapy. After the results of the ISEL trial, the U.S. Food and Drug Administration restricted the use of gefitinib, and gefitinib was effectively removed from routine clinical practice within the U.S. However, gefitinib was approved in other countries and clinical trials investigating gefitinib continued. Recently the Iressa Non-small cell lung cancer Trial Evaluating REsponse and Survival against Taxotere (INTEREST) trial met the primary endpoint of demonstrating noninferiority in terms of overall survival for gefitinib (250 mg daily) in comparison with docetaxel (75 mg/m(2) every 3 weeks). Patients treated with gefitinib experienced a lower rate of treatment-related toxicity and higher rate of improvement in quality of life. Results of recent gefitinib trials have been provocative, and suggest a role for gefitinib in the treatment of advanced NSCLC.

Emerging Therapies for Stage III Non-Small Cell Lung Cancer: Stereotactic Body Radiation Therapy and Immunotherapy.

Kumar, Sameera S; Higgins, Kristin A; McGarry, Ronald C

2017-01-01

The current standard of care for locally advanced non-small cell lung cancer (NSCLC) includes radiation, chemotherapy, and surgery in certain individualized cases. In unresectable NSCLC, chemoradiation has been the standard of care for the past three decades. Local and distant failure remains high in this group of patients, so dose escalation has been studied in both single institution and national clinical trials. Though initial studies showed a benefit to dose escalation, phase III studies examining dose escalation using standard fractionation or hyperfractionation have failed to show a benefit. Over the last 17 years, stereotactic body radiation therapy (SBRT) has shown a high degree of safety and local control for stage I lung cancers and other localized malignancies. More recently, phase I/II studies using SBRT for dose escalation after conventional chemoradiation in locally advanced NSCLC have been promising with good apparent safety. Immunotherapy also offers opportunities to address distant disease and preclinical data suggest immunotherapy in tandem with SBRT may be a rational way to induce an "abscopal effect" although there are little clinical data as yet. By building on the proven concept of conventional chemoradiation for patients with locally advanced NSCLC with a subsequent radiation dose intensification to residual disease with SBRT concurrent with immunotherapy, we hope address the issues of metastatic and local failures. This "quadmodality" approach is still in its infancy but appears to be a safe and rational approach to the improving the outcome of NSCLC therapy.

Questions raised during gemcitabine development reflect non small-cell lung cancer (NSCLC) history during last 10 years. Third generation therapies (gemcitabine, vinorelbine and taxanes) combined with platinium compounds are now to be prescribed in almost all clinical situations, from surgically removed tumors to metastatic diseases. The 30% response rate usually reported in advanced disease (with a median survival of 10 months) has to be improved and a more global approach is nowadays mandatory, including targeted agents. This review sum-up the clinical situations in which gemcitabine can be prescribed (advanced disease), or shall be prescribed (adjuvant setting, combination with anti-angiogenic agent or EGFR inhibitors), and highlight opening questions.

Increasing evidence indicates that the TGFβ/Smad signaling pathway plays a prominent role in tumor initiation, progression, and metastasis. Therefore, we investigate the expression of p-Smad2 in surgical resection specimens from non-small cell lung cancer, and evaluate the prognostic significance of p-Smad2 expression in stromal fibroblasts and cancer cells for patients with clinical stage I to IIIA non-small cell lung cancer. The immunohistochemical expression of p-Smad2 was evaluated in 78 formalin-fixed paraffin-embedded surgical resection specimens from clinical stage I to IIIA non-small cell lung cancer. Correlations between p-Smad2 expression and clinicopathologic characteristics were determined by Chi-square test. The prognostic significance of p-Smad2 expression in stromal fibroblasts and cancer cells with regard to overall survival was determined by Kaplan-Meier. There were 38.5% (30/78) and 92.3% (72/78) patients with high p-Smad2 expression in stromal fibroblasts and cancer cells, respectively. There was a positive correlation between the p-Smad2 expression level in stromal fibroblasts and the p-Smad2 expression level in cancer cells (χ2=4.176, P=0.045). No significant correlation of p-Smad2 expression in stromal fibroblasts or cancer cells with any of clinicopathologic characteristics was found. The 3-year overall survival rates with low and high p-Smad2 expression in stromal fibroblasts were 53.7% and 37.7%, respectively (χ2=3.86, P=0.049). No significant association was found between low and high p-Smad2 expression in cancer cells with respect to overall survival, respectively (χ2=0.34, P=0.562). The results suggested that high p-Smad2 expression in stromal fibroblasts predicted poor survival in patients with clinical stage I to IIIA non-small cell lung cancer.

The molecular investigation of lung cancer has opened up an advanced area for the diagnosis and therapeutic management of lung cancer patients. Gene alterations in cancer initiation and progression provide not only information on molecular changes in lung cancer but also opportunities in advanced therapeutic regime by personalized targeted therapy. EGFR mutations and ALK rearrangement are important predictive biomarkers for the efficiency of tyrosine kinase inhibitor treatment in lung cancer patients. Moreover, epigenetic aberration and microRNA dysregulation are recent advances in the early detection and monitoring of lung cancer. Although a wide range of molecular tests are available, standardization and validation of assay protocols are essential for the quality of the test outcome. In this review, current and new advancements of molecular biomarkers for non-small-cell lung cancer will be discussed. Recommendations on future development of molecular diagnostic services will also be explored.

Ceritinib for treatment of ALK-rearranged advanced non-small-cell lung cancer.

PubMed

Vansteenkiste, Johan F

2014-10-01

The anaplastic lymphoma kinase (ALK) gene plays a key role in the pathogenesis of selected tumors, including non-small-cell lung cancer (NSCLC). Patients with ALK-rearranged NSCLC are initially sensitive to the ALK inhibitor crizotinib but eventually become resistant, limiting its therapeutic potential. Ceritinib is an oral second-generation ALK inhibitor with greater preclinical antitumor potency than crizotinib in ALK-positive NSCLC. A Phase I trial of ceritinib in ALK-positive tumors demonstrated good activity in patients with advanced NSCLC, including those who had progressed on crizotinib. Adverse events are similar to those seen with other ALK tyrosine kinase inhibitors and are generally manageable. Ongoing trials are evaluating ceritinib in patients with ALK-rearranged NSCLC treated with prior chemotherapy and/or crizotinib.

A phase II trial was performed to evaluate the efficacy and toxicity of the novel combination of vinorelbine and paclitaxel as first-line chemotherapy in patients with stages IIIB and IV non-small-cell lung cancer. From January 1997 to September 1999, 34 patients (9 stage IIIB and 25 stage IV) received a regimen consisting of the following: vinorelbine 30 mg/m2 20 minutes intravenous (i.v.) infusion, days 1 and 8; and paclitaxel 135 mg/m2 3-hour i.v. (starting 1 hour after vinorelbine) on day 1. Cycles were repeated every 28 days until progression of disease or unacceptable toxicity development. The median age was 57 years (range 41-70 years); median performance status was 1. Histology was as follows: squamous cell in 24 (71%), large cell in 1 (3%), and adenocarcinoma in 9 (26%). All patients are evaluable for toxicity, whereas 30 are evaluable for response (4 patients refused treatment). Objective response was recorded in 4 of 30 patients (13%, 95% CI 1-25%). No complete response was observed. Partial response was recorded in 4 patients (13%), no change in 10 patients (34%), and progressive disease in 16 patients (53%). The median time to treatment failure was 4 months and median survival was 9 months. The limiting toxicity was myelosuppression: leukopenia in 23 patients (68%), whereas neutropenia was observed in 25 patients (78%). Peripheral neurotoxicity developed in 14 patients (41%) (without G3 or G4 episodes), and constipation (G1-G2: 10 patients), myalgia (G1-G2: 11 patients), diarrhea (G1-G2: 7 patients), and stomatitis were observed in 7 patients. Vinorelbine-paclitaxel combination showed only modest activity against locoregionally advanced or metastatic NSCLC.

About 30% stage I non-small cell lung cancer (NSCLC) patients undergoing resection will recur. Robust prognostic markers are required to better manage therapy options. The purpose of this study is to develop and validate a novel gene-expression signature that can predict tumor recurrence of stage I NSCLC patients. Cox proportional hazards regression analysis was performed to identify recurrence-related genes and a partial Cox regression model was used to generate a gene signature of recurrence in the training dataset −142 stage I lung adenocarcinomas without adjunctive therapy from the Director's Challenge Consortium. Four independent validation datasets, including GSE5843, GSE8894, and two other datasets provided by Mayo Clinic and Washington University, were used to assess the prediction accuracy by calculating the correlation between risk score estimated from gene expression and real recurrence-free survival time and AUC of time-dependent ROC analysis. Pathway-based survival analyses were also performed. 104 probesets correlated with recurrence in the training dataset. They are enriched in cell adhesion, apoptosis and regulation of cell proliferation. A 51-gene expression signature was identified to distinguish patients likely to develop tumor recurrence (Dxy = −0.83, P<1e-16) and this signature was validated in four independent datasets with AUC >85%. Multiple pathways including leukocyte transendothelial migration and cell adhesion were highly correlated with recurrence-free survival. The gene signature is highly predictive of recurrence in stage I NSCLC patients, which has important prognostic and therapeutic implications for the future management of these patients.

At present the treatment of advanced non-small cell lung cancer enters a targeted era and develops rapidly. New drugs appear constantly. Small molecular tyrosine kinase inhibitors have occupied the biggest piece of the territory, which commonly have a clear biomarker as predictor, and show remarkable effect in specific molecular classification of patients. The epidermal growth factor tyrosine kinase inhibitors such as gefitinib, erlotinib, icotinib and anaplastic lymphoma kinase tyrosine kinase inhibitors crizotinib have brought a milestone advance. In recent years new generations of tyrosine kinase inhibitors have achieved a great success in patients with acquired resistance to the above two kinds of drugs. At the same time new therapeutic targets are constantly emerging. So in this paper, we reviewed and summarized the important drugs and clinical trails on this topic, and made a prospect of the future development.

Excision repair cross-complementation group 1 (ERCC1) protein has been associated with cisplatin resistance. The objective of this study was to investigate the correlation between ERCC1 protein levels and the therapeutic effect of individualized therapy in advanced non-small cell lung cancer (NSCLC). A total of 190 advanced NSCLC patients were included in this study. Patients were randomized into either the individualized therapy group or the standard therapy group at a ratio of 2:1. Patients in the standard therapy group were treated with either gemcitabine plus cisplatin or vinorelbine plus cisplatin. The expression of ERCC1 protein in lung cancer tissues of patients from the individualized therapy group was detected with immunohistochemistry. Patients with low ERCC1 levels received either gemcitabine plus cisplatin or vinorelbine plus cisplatin, and patients with high levels received gemcitabine plus vinorelbine. The main outcome assessments were response rate (RR), overall survival (OS) and time to progression (TTP). Follow-up data were recorded until September 30, 2010. RR, 1-year survival rate and TTP were not statistically significant. The median survival time was 10.10 months in the standard therapy group (95% CI 8.48-11.92) and 13.59 months in the individualized therapy group (95% CI 11.86-14.74). The difference in median survival time was significantly different between these groups (P=0.036). The median survival time was longer in the individualized group compared to the standard therapy group. ERCC1 protein expression in advanced NSCLC patients, however, was not significantly correlated with RR, OS and TTP in the individualized therapy group. Therefore, this study suggests that ERCC1 protein levels should be assessed in combination with additional biomarkers to determine an optimal index for individualized therapy in advanced NSCLC patients.

Concurrent chemoradiotherapy (CCRT) is considered the standard treatment regimen in non-surgical locally advanced non-small cell lung cancer (NSCLC) patients and sequential chemoradiotherapy (SCRT) is recommended in patients who are unfit to receive CCRT or when the treatment volume is considered too large. In this study, we investigated the proportion of CCRT/SCRT in the Netherlands and Belgium. Furthermore, patient and disease characteristics associated with SCRT were assessed. An observational study was carried out with data from three independent national registries: the Belgian Cancer Registry (BCR), the Netherlands Cancer Registry (NCR) and the Dutch Lung Cancer Audit-Radiotherapy (DLCA-R). Differences in patient and disease characteristics between CCRT and SCRT were tested with unpaired t-tests (for continuous variables) and with chi-square tests (for categorical variables). A prognostic model was constructed to determine patient and disease parameters predictive for the choice of SCRT. This study included 350 patients from the BCR, 780 patients from the NCR and 428 patients from the DLCA-R. More than half of the stage III NSCLC patients in the Netherlands (55%) and in Belgium more than a third (35%) were treated with CCRT. In both the Dutch and Belgian population, higher age and more advanced N-stage were significantly associated with SCRT. Performance score, pulmonary function, comorbidities and tumour volume were not associated with SCRT. In this observational population-based study, a large treatment variation in non-surgical stage III NSCLC patients was observed between and within the Netherlands and Belgium. Higher age and N-stage were significantly associated with the choice for SCRT. Copyright © 2017 The Royal College of Radiologists. Published by Elsevier Ltd. All rights reserved.

To investigate the feasibility of involved-field irradiation (IFI ) for stage III non-small cell lung cancer (NSCLC). From September 1997 to November 2001, 200 stage-III NSCLC patients were randomly divided into two groups-- IFI and ENI (elective node irradiation). The IFI group was irradiated by 3DCR to a dose of 68-74 Gy/34-37f/7-9 w including the primary tumor and the lymph nodes of > or = 10 mm in short axis. The ENI group was irradiated to a dose of 60-64 Gy/30-32f/6-7.5 w including the primary tumor, ipsilateral hilum, subcarinal and mediastinal lymph nodes, even the supraclavicular area when the lymph nodes of superior mediastinum were involved. The overall response (CR + PR) rates were 90.0% in IFI group and 79.0% in ENI group. Radiation pneumonitis developed in 29.0% of the patients in ENI group and 17.0% in IFI group (P = 0.04). The 1-year primary tumor failure rate in IFI group (13.0%) was lower than that (23.0%) in ENI group. The 1-year involved nodal failure rate was 20.0% in ENI group and 10.0% in IFI group (P = 0.048). The 1-year elective node failure rate was 16.0% in ENI group versus 21.0% in IFI group (P = 0.39). The 1-, 2-and 3-year overall survival rate was 67.2% , 38.7% , 27.3% , respectively, in IFI group; versus 59.7% , 25.6% , 19.2% in ENI group, with a difference significant in the 2-year overall survival rate between IFI and ENI group (P = 0.048). Involved-field 3D-CRT for stage-III non-small cell lung cancer is well tolerated. It does not increase the rate of lymph node failure in the elective node irradiation field, and may improve the survival due to dose escalation.

Effective control of non-small-cell lung cancer (NSCLC) remains clinically challenging, especially during advanced stages of the disease. This study developed an adoptive T-cell treatment through expression of a chimeric antigen receptor (CAR) to target human epidermal growth factor receptor (EGFR) in NSCLC. We optimized the non-viral piggyBac transposon system to engineer human T cells for the expression of EGFR-CAR, consisting of EGFR scFv, transmembrane domain, and intracellular 4-1BB-CD3ζ signaling domains. The modified CAR T cells exhibited expansion capability and anticancer efficacy in a time- and antigen-dependent manner in vitro as well as regression of EGFR-positive human lung cancer xenografts in vivo. EGFR-CAR T therapy is a promising strategy to improve the efficacy and potency of the adoptive immunotherapy in NSCLC. Moreover, EGFR-CAR T therapy could become a clinical application for NSCLC patients in the future.

The purpose of the present study was to retrospectively evaluate impact of pre-treatment skeletal muscle mass (SMM) on overall survival and non-lung cancer mortality after stereotactic body radiotherapy (SBRT) for patients with stage I non-small cell lung cancer (NSCLC). One-hundred and eighty-six patients whose abdominal CT before the treatment was available were enrolled into this study. The patients were divided into two groups of SMM according to gender-specific thresholds for unilateral psoas area. Operability was judged by the treating physician or thoracic surgeon after discussion in a multi-disciplinary tumor board. Patients with low SMM tended to be elderly and underweight in body mass index compared with the high SMM. Overall survival in patients with the low SMM tended to be worse than that in the high SMM (41.1% and 55.9% at 5 years, P = 0.115). Cumulative incidence of non-lung cancer death was significantly worse in the low SMM (31.3% at 5 years compared with 9.7% in the high SMM, P = 0.006). Multivariate analysis identified SMM and operability as significant factors for non-lung cancer mortality. Impact of SMM on lung cancer death was not significant. No difference in rate of severe treatment-related toxicity was observed between the SMM groups. Low SMM is a significant risk factor for non-lung cancer death, which might lead to worse overall survival, after SBRT for stage I NSCLC. However, the low SMM does not increase lung cancer death or severe treatment-related toxicity. Copyright © 2018 Elsevier Inc. All rights reserved.

The expression of cancer/testis antigens SSX2, SSX3, and SSX4 in non-small cell lung cancers (NSCLC) was examined, since they are considered promising targets for cancer immunotherapy due to their immunogenicity and testis-restricted normal tissue expression. We characterized three SSX antibodies and performed immunohistochemical staining of 25 different normal tissues and 143 NSCLCs. The antibodies differed in binding to two distinctive splice variants of SSX2 that exhibited different subcellular staining patterns, suggesting that the two splice variants display different functions. SSX2-4 expression was only detected in 5 of 143 early-stage NSCLCs, which is rare compared to other cancer/testis antigens (e.g. MAGE-A and GAGE). However, further studies are needed to determine whether SSX can be used as a prognostic or predictive biomarker in NSCLC. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Objectives Pemetrexed inhibits folate-dependent enzymes involved in pyrimidine and purine synthesis. Prior studies of genetic variation in these enzymes as predictors of pemetrexed efficacy have yielded inconsistent results. We investigated whether red blood cell (RBC) total folate, a phenotypic rather than genotypic marker of cellular folate status, was associated with response to pemetrexed-based chemotherapy in advanced non-squamous non-small-cell lung cancer (NSCLC). Materials and methods We conducted a prospective cohort study of patients with stage IV non-squamous NSCLC receiving first-line chemotherapy containing pemetrexed. Pretreatment RBC total folate was quantified using liquid chromatography/mass spectrometry. We then compared objective response rate (ORR) between patients with RBC total folate concentrations above and below an optimal cut-off value determined from the receiver operating characteristic (ROC) curve. A logistic regression model was used to adjust for age, sex, and use of bevacizumab. Results The ORR was 62% (32 of 52 patients). ROC analysis was used to establish that a RBC total folate cutoff value of 364.6 nM optimally discriminated between pemetrexed responders and non-responders. Patients with RBC total folate below 364.5 nM had an ORR of 27%, compared to 71% in patients with RBC total folate above this value (p=0.01). This difference persisted after adjusting for age, sex, and use of bevacizumab (OR 0.07, 95% CI 0.01 - 0.57, p=0.01). Conclusions Low pretreatment RBC total folate is associated with inferior response to pemetrexed-based chemotherapy in stage IV non-squamous NSCLC. Larger, multicenter studies are needed to validate RBC total folate as a predictive marker of pemetrexed response. PMID:27863923

Although epidermal growth factor receptor (EGFR)- and anaplastic lymphoma kinase (ALK)-directed therapies are not approved for patients with early-stage non-small cell lung carcinoma (NSCLC), many institutions perform EGFR and ALK testing for all patients with NSCLC at the time of initial diagnosis. Current consensus guidelines recommend EGFR testing and suggest ALK testing at the time of initial diagnosis for patients with advanced disease. To examine the cost and clinical impact of EGFR and ALK testing of patients with early-stage NSCLC. Records from all patients with a diagnosis of NSCLC made on a nonresection specimen at our institution during a single calendar year (2012) were reviewed, and a cost analysis was performed. Of 133 total patients, 47 (35%) had early-stage (stage I or II) disease and 86 (65%) had locally advanced (stage III) or advanced (stage IV) disease at presentation. Eight of 47 patients with early-stage disease (17%) had progression/recurrence during 18 to 30 months of follow-up, 6 of 8 (75%) of whom had pathologic confirmation of progression/recurrence. The estimated additional cost of EGFR and ALK testing for all newly diagnosed patients with NSCLC at our institution is $75,200 per year, compared to testing only patients with locally advanced and advanced-stage disease. The cost of universal molecular testing of NSCLC is substantial. EGFR and ALK testing of patients with early-stage disease appears to have negligible clinical impact, as most patients do not have disease recurrence/progression. Those whose disease recurs/progresses typically undergo rebiopsy. Our findings do not support the practice of universal EGFR and ALK testing in NSCLC at the time of initial diagnosis.

2017-01-01

Lung cancer is one of the most common causes of cancer-related death in the world. The large number of lung cancer cases is non-small cell lung cancer (NSCLC), which approximately accounting for 75% of lung cancer. Over the past years, our comprehensive knowledge about the molecular biology of NSCLC has been rapidly enriching, which has promoted the discovery of driver genes in NSCLC and directed FDA-approved targeted therapies. Of course, the targeted therapies based on driver genes provide a more exact option for advanced non-small cell lung cancer, improving the survival rate of patients. Now, we will review the landscape of driver genes in NSCLC including the characteristics, detection methods, the application of target therapy and challenges. PMID:28915704

Around 4% of advanced non-small cell lung cancers (NSCLC) harbor a ALK rearrangement, with high sensitivity to ALK inhibitor as crizotinib. However, the vast majority of these tumors end with a tumor progression after several months of treatment with crizotinib. Ceritinib is a 2nd generation ALK inhibitor, which showed high efficiency in NSCLC with ALK rearrangement. Results from phase I trial showed a response rate at 58% in these tumors, with a similar rate for previously crizotinib-treated patients or crizotinib-naïve patients. Moreover, cerebral responses were observed with ceritinib. Preliminary date from a phase 2 trial confirmed these results. These promising results allowed a European marketing authorization (autorisation de mise sur le marché [AMM]) since May 2015 for the treatment of advanced NSCLC with ALK rearrangement and resistance or intolerance to crizotinib.

studies were conducted, and the age of the studies (> 20 years). The methods of cancer staging and types of surgical procedures, which do not reflect current practice, reduced our confidence in the estimation of the effect.Two studies compared surgery to radiation therapy, and in one study chemotherapy was administered to both arms. One study administered initial chemotherapy, then responders were randomised to surgery versus control; following, both groups underwent chest and whole brain irradiation.Due to the clinical heterogeneity of the trials, we were unable to pool results for meta-analysis.All three studies reported overall survival. One study reported a mean overall survival of 199 days in the surgical arm, compared to 300 days in the radiotherapy arm (P = 0.04). One study reported overall survival as 4% in the surgical arm, compared to 10% in the radiotherapy arm at two years. Conversely, one study reported overall survival at two years as 52% in the surgical arm, compared to 18% in the radiotherapy arm. However this difference was not statistically significant (P = 0.12).One study reported early postoperative mortality as 7% for the surgical arm, compared to 0% mortality in the radiotherapy arm. One study reported the difference in mean degree of dyspnoea as -1.2 comparing surgical intervention to radiotherapy, indicating that participants undergoing radiotherapy are likely to experience more dyspnoea. This was measured using a non-validated scale. Evidence from currently available RCTs does not support a role for surgical resection in the management of limited-stage small-cell lung cancer; however our conclusions are limited by the quality of the available evidence and the lack of contemporary data. The results of the trials included in this review may not be generalisable to patients with clinical stage 1 small-cell lung cancer carefully staged using contemporary staging methods. Although some guidelines currently recommend surgical resection in clinical stage

ILD-NSCLC-GAP index scoring and staging system for patients with non-small cell lung cancer and interstitial lung disease.

Patients with advanced non-small cell lung cancer (NSCLC) and interstitial lung disease (ILD) are commonly excluded from most clinical trials because of acute exacerbation (AE) of ILD triggered by chemotherapy. Data on the efficacy and feasibility of chemotherapy are limited in this patient population. Recently, the ILD-GAP index and staging system was reported as a clinical prognostic factor associated with mortality in patients with ILD. Therefore, we evaluated the incidence of ILD-AE during the surveillance term in this study and the prognosis in patients with NSCLC and ILD using a modified ILD-GAP (ILD-NSCLC-GAP) index scoring system. The medical records of patients with NSCLC and ILD who underwent a pulmonary function test before initiation of platinum-based chemotherapy as first-line treatment at the Shizuoka Cancer Center between September 2002 and December 2014 were reviewed retrospectively. Among these patients, we compared the incidence of ILD-AE, one-year survival rate, and overall survival (OS) between the ILD-NSCLC-GAP index scores and stages. Of the 78 patients included, 21 (27%; 95% confidence interval [CI], 18%-38%) had ILD-AE during the surveillance term in this study. The one-year survival and median OS rates were 49% and 11.3 months, respectively. The incidence of ILD-AE increased gradually and the one-year survival and median OS rates decreased gradually with increasing ILD-NSCLC-GAP index scores and stages. The ILD-NSCLC-GAP index scoring and staging system may be a useful tool to calculate a prediction of the incidence of ILD-AE and its prognosis for patients with NSCLC and ILD.

To examine possible associations between socioeconomic position and surgical treatment of patients with early-stage non-small-cell lung cancer (NSCLC). In a register-based clinical cohort study, patients with early-stage (stages I-IIIa) NSCLC were identified in the Danish Lung Cancer Register 2001-2008 (date of diagnosis, histology, stage, and treatment), the Central Population Register (vital status), the Integrated Database for Labour Market Research (socioeconomic position), and the Danish Hospital Discharge Register (comorbidity). Logistic regression analyses were performed overall and separately for stages I, II and IIIa. Of the 5538 eligible patients with stages I-IIIa NSCLC diagnosed 2001-2008, 53% underwent surgery. Higher stage, older age, being female and diagnosis early in the study period were associated with higher odds for not receiving surgery. Low disposable income was associated with greater odds for no surgery in stage I and stage II patients as was living alone for stage I patients. Comorbidity, a short diagnostic interval and small diagnostic volume were all associated with higher odds for not undergoing surgery; but these factors did not appear to explain the association with income or living alone for early-stage NSCLC patients. Early-stage NSCLC patients with low income or who live alone are less likely to undergo surgery than those with a high income or who live with a partner, even after control for possible explanatory factors. Thus, even in a health care system with free, equal access to health services, disadvantaged groups are less likely to receive surgery for lung cancer. Copyright © 2012 Elsevier Ireland Ltd.

The present study compared the dose-volume histograms of patients with Stage IIIA non-small cell lung cancer (NSCLC) treated with carbon ion radiotherapy with those of patients treated with X-ray radiotherapy. Patients with Stage IIIA NSCLC (n = 10 patients for each approach) were enrolled. Both radiotherapy plans were calculated with the same targets and organs at risk on the same CT. The treatment plan for the prophylactic lymph node and primary tumor (PTV1) delivered 40 Gy for X-ray radiotherapy and 40 Gy (relative biological effectiveness; RBE) for carbon ion radiotherapy. The total doses for the primary tumor and clinically positive lymph nodes (PTV2) were 60 Gy for X-ray radiotherapy and 60 Gy (RBE) for carbon ion radiotherapy. The homogeneity indexes for PTV1 and PTV2 were superior for carbon ion radiotherapy in comparison with X-ray radiotherapy (PTV1, 0.57 vs 0.65, P = 0.009; PTV2, 0.07 vs 0.16, P = 0.005). The normal lung mean dose, V5, V10 and V20 for carbon ion radiotherapy were 7.7 Gy (RBE), 21.4%, 19.7% and 17.0%, respectively, whereas the corresponding doses for X-ray radiotherapy were 11.9 Gy, 34.9%, 26.6% and 20.8%, respectively. Maximum spinal cord dose, esophageal maximum dose and V50, and bone V10, V30 and V50 were lower with carbon ion radiotherapy than with X-ray radiotherapy. The present study indicates that carbon ion radiotherapy provides a more homogeneous target dose and a lower dose to organs at risk than X-ray radiotherapy for Stage IIIA non-small cell lung cancer. © The Author 2016.

A prognostic test was developed to guide adjuvant chemotherapy (ACT) decisions in early-stage non-small cell lung cancer (NSCLC) adenocarcinomas. The objective of this study was to compare the cost-utility of the prognostic test to the current standard of care (SoC) in patients with early-stage NSCLC. Lifetime costs (2014 U.S. dollars) and effectiveness (quality-adjusted life-years [QALYs]) of ACT treatment decisions were examined using a Markov microsimulation model from a U.S. third-party payer perspective. Cancer stage distribution and probability of receiving ACT with the SoC were based on data from an academic cancer center. The probability of receiving ACT with the prognostic test was estimated from a physician survey. Risk classification was based on the 5-year predicted NSCLC-related mortality. Treatment benefit with ACT was based on the prognostic score. Discounting at a 3% annual rate was applied to costs and QALYs. Deterministic one-way and probabilistic sensitivity analyses examined parameter uncertainty. Lifetime costs and effectiveness were $137,403 and 5.45 QALYs with the prognostic test and $127,359 and 5.17 QALYs with the SoC. The resulting incremental cost-effectiveness ratio for the prognostic test versus the SoC was $35,867/QALY gained. One-way sensitivity analyses indicated the model was most sensitive to the utility of patients without recurrence after ACT and the ACT treatment benefit. Probabilistic sensitivity analysis indicated the prognostic test was cost-effective in 65.5% of simulations at a willingness to pay of $50,000/QALY. The study suggests using a prognostic test to guide ACT decisions in early-stage NSCLC is potentially cost-effective compared with using the SoC based on globally accepted willingness-to-pay thresholds. Providing prognostic information to decision makers may help some patients with high-risk early stage non-small cell lung cancer receive appropriate adjuvant chemotherapy while avoiding the associated toxicities and

Non-small cell lung cancer brain metastasis screening in the era of positron emission tomography-CT staging: Current practice and outcomes.

PubMed

Several clinical guidelines indicate that brain metastasis screening (BMS) should be guided by disease stage in non-small cell lung cancer (NSCLC). We estimate that screening is performed more broadly in practice, and patients undergo brain imaging at considerable cost with questionable benefit. Our aim was to quantify the use and detection rate of BMS in a contemporary cohort staged with 18 F-fluorodeoxyglucose positron emission tomography/computed tomography (PET-CT). We conducted a retrospective review of prospectively collected data from three major lung cancer referral centres in Brisbane between January 2011 and December 2015. Patients included had a new diagnosis of NSCLC and had undergone a PET-CT to stage extra-cranial disease. BMS was defined as dedicated brain imaging with contrast-enhanced computed tomography (CE-CT) or magnetic resonance (MR), in the absence of clinically apparent neurological deficits. A total of 1751 eligible cases were identified and of these 718 (41%) underwent BMS. The majority had CE-CT imaging (n = 703). Asymptomatic brain metastases (BM) were detected in 18 patients (2.5%). Of these patients, 12 had concurrent non-brain metastases. Only six patients (0.8%) had BM alone. The rate of detection increased with N-stage (P = 0.02) and overall stage (P < 0.001). It was 0.5%, 1%, 1.6% and 7.3% for stage I, II, III and IV respectively. The overall screening rate increased with T-stage (P = 0.001), N-Stage (P < 0.001) and overall stage (P < 0.001). Non-small cell lung cancer BMS practices remain at odds with published guidelines. The low number of occult BMs detected supports the existing international recommendations. Rationalising BMS would minimise the burden on patients and the health care system. © 2018 The Royal Australian and New Zealand College of Radiologists.

Background This study aimed to understand the role of myeloid cell clusters in uninvolved regional lymph nodes from early stage non-small cell lung cancer patients. Methods Uninvolved regional lymph node sections from 67 patients with stage I–III resected non-small cell lung cancer were immunostained to detect myeloid clusters, STAT3 activity and occult metastasis. Anthracosis intensity, myeloid cluster infiltration associated with anthracosis and pSTAT3 level were scored and correlated with patient survival. Multivariate Cox regression analysis was performed with prognostic variables. Human macrophages were used for in vitro nicotine treatment. Results CD68+ myeloid clusters associated with anthracosis and with an immunosuppressive and metastasis-promoting phenotype and elevated overall STAT3 activity were observed in uninvolved lymph nodes. In patients with a smoking history, myeloid cluster score significantly correlated with anthracosis intensity and pSTAT3 level (P<0.01). Nicotine activated STAT3 in macrophages in long-term culture. CD68+ myeloid clusters correlated and colocalized with occult metastasis. Myeloid cluster score was an independent prognostic factor (P = 0.049) and was associated with survival by Kaplan-Maier estimate in patients with a history of smoking (P = 0.055). The combination of myeloid cluster score with either lymph node stage or pSTAT3 level defined two populations with a significant difference in survival (P = 0.024 and P = 0.004, respectively). Conclusions Myeloid clusters facilitate a pro-metastatic microenvironment in uninvolved regional lymph nodes and associate with occult metastasis in early stage non-small cell lung cancer. Myeloid cluster score is an independent prognostic factor for survival in patients with a history of smoking, and may present a novel method to inform therapy choices in the adjuvant setting. Further validation studies are warranted. PMID:23717691

To date, lung cancer is still the leading cause of cancer-related mortality worldwide, with the majority of lung cancers arising in the elderly. As a consequence, we can expect an increase in the number of older lung cancer patients considered suitable for chemotherapy in the near future. Elderly patients often have comorbid conditions and progressive physiologic reduction of organ function, which can make the selection of proper treatment daunting. Some patients will be able to tolerate chemotherapy as well as their younger counterparts, whereas others will experience severe toxicity and require treatment modifications. Thus, a major issue is effectively selecting patients suitable for standard or attenuated therapy. A comprehensive geriatric assessment performed at baseline is a useful tool that can help select the best treatment regimen to be administered to elderly patients. Until now, few trials have specifically focused on elderly patients affected by non-small cell lung cancer (NSCLC), particularly those with advanced disease; prospective elderly-specific studies in early stages are still lacking. High priority should be given to evaluating the role of new targeted therapies. Unfortunately, to date, clinical trials that include functional status and comorbidity as part of the geriatric assessment are rare. Future trials, specifically in the elderly population, should include these kinds of evaluations. The most recent therapies for the treatment of elderly patients with NSCLC will be discussed here.

To evaluate the incidence, predictors, and survival of unexpected pN2 disease in patients with clinical stage I non-small cell lung cancer. This is a retrospective observational multicenter study on all consecutive patients operated for clinical stage I non-small cell lung cancer from January 2006 to December 2012. Medical records were reviewed to investigate the incidence and risk factors for unexpected pN2 disease. Then, the survival of patients with unexpected pN2 disease was statistically compared with that of patients with clinical N2 disease operated after induction therapy in the same period. Our study population counted 901 patients. An incidence of 12% (108/901) unexpected pN2 disease was found. Among 3,389 lymph nodes sampled, 124 distinct metastases were found. Of the 108 patients, 92 (85%) had metastases in single N2 station and 16 (15%) patients had disease in multiple N2 stations; 47 (44%) had pN2 disease without pN1 involvement (skip metastases) and 61/108 (56%) had also pN1 metastases. Factors associated with unexpected pN2 disease were central tumor location (p < 0.003), cT2a (p < 0.0001) and pT2a stage (p < 0.0001), pN1 disease (p = 0.004), and a standard uptake value > 4.0 (0.007). Patients with pN2 disease compared with patients with cN2 disease presented a better median overall survival (56 versus 20 months; p = 0.001) and disease-free survival (46 versus 11 months; p < 0.0001). The preoperative effort to discover unexpected pN2 disease in patients with clinical stage I non-small cell lung cancer is not justified, considering their good survival. Thus, preoperative invasive mediastinal procedures in such cases are not indicated. Georg Thieme Verlag KG Stuttgart · New York.

Immune Checkpoint Inhibitors for Patients With Advanced Non-Small-Cell Lung Cancer: A Systematic Review.

2017-09-01

Second-line treatment options are limited for patients with advanced non-small-cell lung cancer (NSCLC). Standard therapy includes the cytotoxic agents docetaxel and pemetrexed, and the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors erlotinib and gefitinib. Immune checkpoint inhibitors are a new class of treatment that have shown durable overall radiologic response rates and have been well tolerated. The objective of this systematic review was to investigate the efficacy of immune checkpoint inhibitors compared with other chemotherapies in patients with advanced NSCLC. Medline, Embase, and PubMed were searched for randomized controlled trials comparing treatment with immune checkpoint inhibitors against treatment with chemotherapy in patients with stage IIIB or IV NSCLC. Nine randomized controlled trials with 15 publications were included. A significant overall survival benefit of second-line nivolumab (nonsquamous: hazard ratio [HR] = 0.72, 95% confidence interval [CI], 0.60-0.77; P < .001; squamous: HR = 0.59, 95% CI, 0.44-0.79; P < .001) or second-line atezolizumab (HR = 0.73, 95% CI, 0.62-0.87; P = .0003) or second-line pembrolizumab (in patients with programmed cell death ligand 1 [PD-L1]-positive tumors) (pembrolizumab 2 mg/kg HR = 0.71, 95% CI, 0.58-0.88; P = .0008; pembrolizumab 10 mg/kg HR = 0.61, 95% CI, 0.49-0.75; P < .0001) or first-line pembrolizumab (HR = 0.60, 95% CI, 0.41-0.89; P = .005) compared with chemotherapy was found. The adverse effects were mainly higher in the chemotherapy arms. For patients with advanced stage IIIB/IV NSCLC, the improvement in overall survival outweighed the harms and supported the use of first-line pembrolizumab (in patients with ≥ 50% PD-L1-positive tumors) or second-line nivolumab, atezolizumab, or pembrolizumab (in patients with PD-L1-positive tumors).

Simultaneous genotyping has advantages in turnaround time and detecting the real mutational prevalence in unresectable non-small-cell lung cancer (NSCLC), a group not previously genetically characterized. We developed simultaneous panel of screening EGFR and KRAS mutations by direct sequencing or PNA clamping, and ALK rearrangement by fluorescent in situ hybridization (FISH) in multicenter manner. Of 510 NSCLC Korean patients, simultaneous genotyping identified mutations of EGFR (29.0%) and KRAS (8.6%) and rearrangement of ALK (9.2%). Seven patients had overlaps in mutations. Although several well-known associations between genotypes and clinical characteristics were identified, we found no relationship between ALK rearrangement and sex or smoking history. Unlike the other genotype mutations, ALK rearrangement was associated with advanced disease. Among the ALK-negative group, patients with 10-15% of ALK FISH split shared characteristics, such as younger age and advanced stage disease, more with the ALK-positive group (>15% ALK FISH split) than <10% ALK FISH split group. Simultaneous panel genotyping revealed more prevalent ALK rearrangements than reported in previous studies and their strong association with advanced stage irrespective of sex or smoking history. ALK rearrangement seems to be a marker for aggressive tumor biology and should be assessed in advanced disease. © 2014 Wiley Periodicals, Inc.

Previous studies indicate that the role of B lymphoma Mo-MLV insertion region 1 homolog (Bmi-1) is responsible for multiple cancer progression. However, Bmi-1 in controlling gene expression in non-small cell lung cancer (NSCLC) development is not well explored. Here we report that the Bmi-1 level is highly increased in primary NSCLC tissues compared to matched adjacent non-cancerous tissues and required for lung tumor growth in xenograft model. Furthermore, we also demonstrate that Bmi-1 level is lower in matched involved lymph node cancerous tissues than the respective primary NSCLC tissues. We find that Bmi-1 does not affect cell cycle and apoptosis in lung cancer cell lines as it does not affect the expression of p16/p19, Pten, AKT and P-AKT. Mechanistic analyses note that reduction of Bmi-1 expression inversely regulates invasion and metastasis of NSCLC cells in vitro and in vivo, followed by induction of epithelial-mesenchymal transition (EMT). Using genome microarray assays, we find that RNAi-mediated silence of Bmi-1 modulates some important molecular genetics or signaling pathways, potentially associated with NSCLC development. Taken together, our findings disclose for the first time that Bmi-1 level accumulates strongly in early stage and then declines in late stage, which is potentially important for NSCLC cell invasion and metastasis during progression.

To assess the cost-effectiveness of first-line pemetrexed/platinum and other commonly administered regimens in a representative US elderly population with advanced non-squamous non-small cell lung cancer (NSCLC). This study utilized the Surveillance Epidemiology and End Results (SEER) cancer registry linked to Medicare claims records. The study population included all SEER-Medicare patients diagnosed in 2008-2009 with advanced non-squamous NSCLC (stages IIIB-IV) as their only primary cancer and who started chemotherapy within 90 days of diagnosis. The study evaluated the four most commonly observed first-line regimens: paclitaxel/carboplatin, platinum monotherapy, pemetrexed/platinum, and paclitaxel/carboplatin/bevacizumab. Overall survival and total healthcare cost comparisons as well as incremental cost-effectiveness ratios (ICERs) were calculated for pemetrexed/platinum vs each of the other three. Unstratified analyses and analyses stratified by initial disease stage were conducted. The final study population consisted of 2,461 patients. Greater administrative censorship of pemetrexed recipients at the end of the study period disproportionately reduced the observed mean survival for pemetrexed/platinum recipients. The disease stage-stratified ICER analysis found that the pemetrexed/platinum incurred total Medicare costs of $536,424 and $283,560 per observed additional year of life relative to platinum monotherapy and paclitaxel/carboplatin, respectively. The pemetrexed/platinum vs triplet comparator analysis indicated that pemetrexed/platinum was associated with considerably lower total Medicare costs, with no appreciable survival difference. Limitations included differential censorship of the study regimen recipients and differential administration of radiotherapy. Pemetrexed/platinum yielded either improved survival at increased cost or similar survival at reduced cost relative to comparator regimens in the treatment of advanced non-squamous NSCLC.

We conducted long-term follow-up analysis of the outcomes for patients affected by advanced-stage non-small cell lung cancer (NSCLC) treated with hypofractionated radiotherapy (RT). Sixty patients with advanced-stage NSCLC (IIIA-IV) treated with hypofractionated radiotherapy (60Gy/20 fractions) were analyzed. Radiation was delivered using an image-guided RT technique to verify the correct position. Toxicities were graded according to the Common Toxicity Criteria for Adverse Effects v4.0 scale. Overall, six patients achieved a complete response and 46 patients had a partial response (tumor response rate 86%). After a median follow-up of 30 months, locoregional progression occurred in 23 patients and distant progression occurred in 38. The 1-year and 2-years overall survival were 57% and 40%, respectively. The 1-year and 2-years progression-free survival (PFS) were 47.1% and 33.5%, respectively. The median duration of OS and PFS was 13 months and 12 months, respectively. The 2-year local PFS and metastases-free survival (MFS) were 53% and 40.3%, respectively. On univariate analysis, the T-size (≥5 cm), and type of response to RT (non-response/progressive disease) were significantly associated with worse OS. Type of response was identified as significant prognostic factors for PFS (p<0.01) local PFS (p=0.015) and MFS (p<0.01). Acute grade 3 esophagitis and pneumonitis occurred in three patients (5%) and four patients (6%), respectively. Late grade 3 esophagitis and pneumonitis occurred in 2% (one patient) and 3% (two patients), respectively. No patient experienced grade 4 acute or late RT-related toxicities. Hypofractionated RT offers good disease control for patients with advanced-stage NSCLC with acceptable toxicity rates. Phase III randomized trials are necessary to compare hypofractionated RT with conventional RT. Copyright© 2015 International Institute of Anticancer Research (Dr. John G.

Lung cancer is the leading cause of cancer-associated death, and non-small cell lung cancer (NSCLC) accounts for 85% of all lung cancer cases. Many drugs have been used to treat NSCLC in order to improve patient prognosis. Platinum-based chemotherapy is the first-line treatment for locally advanced or metastatic patients. For patients with activating EGFR mutations, tyrosine kinase inhibitors are the best treatment choice. NSCLC initially exhibits an excellent response to treatment; however, acquired resistance has been observed in many patients, leading to ineffective treatment. Clinical resistance is an impediment in the treatment of patients with advanced NSCLC. Many sequencing technologies have shown that long non-coding RNA (lncRNA) is expressed differently between drug-resistant and drug-sensitive lung cancer cells. We review the literature on lncRNA in drug resistance of NSCLC. The aim of this review is to gain insight into the molecular mechanisms of drug resistance, mainly focusing on the role of lncRNA in NSCLC. © 2018 The Authors.

During this enduring, learner-driven, interactive CME webseries, lung cancer specialists will address the science and targeted therapies for the MET pathway in non-small cell lung cancer. Over the past decade, research has evolved in the science of identifying targeted biological changes in DNA and individual cancer cells. Along with the advanced understanding of lung cancer mutations, has come the development of specific targeted therapies that improve patient outcomes. The first step in treating a patient with lung cancer is proper diagnosis and staging, applying to the principles of personalize medicine. Our current understanding of lung cancer is that of a collection of diseases individualized through specific mutations. This CME activity reviews the role of the pulmonologist and pathologist in proper tissue acquisition and analysis. This new era of personalized medicine and clinical research advances has changed the way clinicians evaluate and treat patients with lung cancer. The data on lung cancer cell mutations and newer targeted therapies have improved the progression free survival and quality of life of lung cancer patients. This CME activity is designed to present a practical overview of recent evidenced based data of MET targeted therapies for patients with lung cancer. As research continues to evolve, we continue to advance our understanding in the science of lung cancers involving the MET pathway. Evidenced based data supporting newer targeted therapeutics provides insight on applying treatment for optimal outcomes. This CME activity will focus on the individualized treatment strategies using practical decision making for patients with MET expression. This activity has been designed to meet the educational needs of medical oncologists, pathologists, radiation oncologists, surgeons, pulmonologists, internists, and other healthcare clinicians responsible for the care of patients with lung cancer.

Many tumors increase uptake and dependence on glucose, cystine or glutamine. These basic observations on cancer cell metabolism have opened multiple new diagnostic and therapeutic avenues in cancer research. Recent studies demonstrated that smoking could induce the expression of xCT (SLC7A11) in oral cancer cells, suggesting that overexpression of xCT may support lung tumor progression. We hypothesized that overexpression of xCT occurs in lung cancer cells to satisfy the metabolic requirements for growth and survival. Our results demonstrated that 1) xCT was highly expressed at the cytoplasmic membrane in non-small cell lung cancer (NSCLC), 2) the expression of xCT was correlated with advanced stage and predicted a worse 5-year survival, 3) targeting xCT transport activity in xCT overexpressing NSCLC cells with sulfasalazine decreased cell proliferation and invasion in vitro and in vivo and 4) increased dependence on glutamine was observed in xCT overexpressed normal airway epithelial cells. These results suggested that xCT regulate metabolic requirements during lung cancer progression and be a potential therapeutic target in NSCLC.

One of the standard options in the treatment of stage IIIA/N2 non-small-cell lung cancer is neoadjuvant chemotherapy and surgery. We did a randomised trial to investigate whether the addition of neoadjuvant radiotherapy improves outcomes. We enrolled patients in 23 centres in Switzerland, Germany and Serbia. Eligible patients had pathologically proven, stage IIIA/N2 non-small-cell lung cancer and were randomly assigned to treatment groups in a 1:1 ratio. Those in the chemoradiotherapy group received three cycles of neoadjuvant chemotherapy (100 mg/m(2) cisplatin and 85 mg/m(2) docetaxel) followed by radiotherapy with 44 Gy in 22 fractions over 3 weeks, and those in the control group received neoadjuvant chemotherapy alone. All patients were scheduled to undergo surgery. Randomisation was stratified by centre, mediastinal bulk (less than 5 cm vs 5 cm or more), and weight loss (5% or more vs less than 5% in the previous 6 months). The primary endpoint was event-free survival. Analyses were done by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00030771. From 2001 to 2012, 232 patients were enrolled, of whom 117 were allocated to the chemoradiotherapy group and 115 to the chemotherapy group. Median event-free survival was similar in the two groups at 12·8 months (95% CI 9·7-22·9) in the chemoradiotherapy group and 11·6 months (8·4-15·2) in the chemotherapy group (p=0·67). Median overall survival was 37·1 months (95% CI 22·6-50·0) with radiotherapy, compared with 26·2 months (19·9-52·1) in the control group. Chemotherapy-related toxic effects were reported in most patients, but 91% of patients completed three cycles of chemotherapy. Radiotherapy-induced grade 3 dysphagia was seen in seven (7%) patients. Three patients died in the control group within 30 days after surgery. Radiotherapy did not add any benefit to induction chemotherapy followed by surgery. We suggest that one definitive local treatment modality combined with

Nowadays, comprehensive treatment, including surgery, chemotherapy and radiotherapy is advocated for stage III non-small cell lung cancer (NSCLC). However, many researchers have questioned the effectiveness of surgery. The aim of this study is to evaluate the effect of surgery for stage III NSCLC. Between March 2002 and October 2012, 310 cases that have completed followed-up data with stage III NSCLC were received in the Peking Union Medical College Hospital. They were divided into surgical and non-surgical groups according to whether received surgery when diagnosed. In TNM staging, stage III NSCLC includes stage IIIa and IIIb, and stage IIIa NSCLC can be grouped into stage T4N0/T3-4N1M0 and T1-3N2M0 according to different N stages. Analyzed the enumeration data by Chi-Square test. Kaplan-Meier survival method was used to calculate the overall survival (OS) and progression-free survival (PFS), and to draw the survival curves. A P value less than 0.05 was evaluated as statistically significant. Three hundred and ten stage III NSCLC patients include surgical group 189 cases and non-surgical group 121 cases. One hundred and eighty-eight stage IIIa NSCLC patients include surgical group 152 cases and non-surgical group 36 cases. In stage IIIa, stage T4N0/T3-4N1M0 had 57 patients with 44 surgical and 13 non-surgical patients, and stage T1-3N2M0 had 131 patients with 108 surgical and 23 non-surgical patients. Thirty-seven out of 121 stage IIIb NSCLC patients received surgery. They had 22 stage T4N2M0 cases and 15 stage T1-4N3M0 cases. The patient whose performance status was 0 and staging was stage IIIa was more inclined to undergo surgery. For stage IIIa NSCLC patients, the median OS of surgical and non-surgical groups were 38.9 and 21.8 months, and the median PFS of them were 19.2 and 11.9 months respectively. The difference of OS between the two groups was significant (P=0.041), but the PFS of them had no significant difference (P=0.209). For stage T4N0/T3-4N1M0 which

Many patients with non-small cell lung cancer (NSCLC) die within the first few years of diagnosis, and considerable excess mortality remains even after 5 years. We investigated the death rate and the distribution of causes of death for NSCLC patients by age and stage at diagnosis during long-term follow-up. All 72 021 patients aged 45-89 years diagnosed with stage I-III NSCLC between 1989 and 2008 in the Netherlands and who died up till 2011 were derived from the Netherlands Cancer Registry and linked with the database of Statistics Netherlands for underlying causes of death. Mortality ratios and proportional distribution of causes of death were calculated during 5 time periods after diagnosis of NSCLC (up to 15 years). Median follow-up was 9.6 years (range: 0-23 years). Lung cancer was the predominant cause of death in the first 6 years after diagnosis (being 80%-85% and ∼90% up to 3 years for localized and locally advanced disease, respectively, and ∼60%-75% and ∼75%-85% during years 4-6 for both stage groups, respectively). Thereafter, lung cancer as cause of death proportionally decreased with time since diagnosis, but remained over 30%. Hence, cardiovascular diseases and chronic obstructive pulmonary diseases (COPD) became more important causes of death, especially for patients aged >60 years at diagnosis (up to 34% for cardiovascular diseases and up to 19% for COPD). With time, the relative contribution of cardiovascular and COPD causes of death increased, although the absolute contribution of lung cancer remained high in non-metastatic NSCLC. Therefore, managing morbidity of these diseases remains relevant. © The Author 2015. Published by Oxford University Press on behalf of the European Society for Medical Oncology. All rights reserved.

Clinical staging of non-small cell lung cancer (NSCLC) determines the initial treatment offered to a patient. The similarity between clinical and pathologic staging in some studies is as low as 50%, and others publish results as high as 91%. The Dutch Lung Surgery Audit is a clinical database that registers the clinical and pathologic TNM of almost all NSCLC patients who undergo operations in the Netherlands. The objective of this study was to determine the accuracy of clinical staging of NSCLC. Prospective data were derived from the Dutch Lung Surgery Audit in 2013 and 2014. Patients were included if they had undergone a surgical resection for stage IA to IIIB NSCLC without neoadjuvant treatment and had a positron emission tomography-computed tomography scan as part of the clinical workup. Clinical (c)TNM and pathologic (p)TNM were compared, and whether discrepancy was based on tumor or nodal staging was determined. From 2,834 patients identified, 2,336 (82.4%) fulfilled the inclusion criteria and had complete data. Of these 2,336, 1,276 (54.6%) were staged accurately, 707 (30.3%) were clinically understaged, and 353 (15.1%) were clinically overstaged. In the understaged group, 346 patients had a higher pN stage (14.8%), of which 148 patients had unforeseen N2 disease (6.3%). In the overstaged group, 133 patients had a cN that was higher than the pN (5.7%). Accuracy of NSCLC staging in the Netherlands is low (54.6%), even in the era of positron emission tomography-computed tomography. Especially accurate nodal staging remains challenging. Future efforts should include the identification of specific pitfalls in NSCLC staging. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Although curative resection is expected to be effective in patients with clinical (c-) stage IA/pathological (p-) stage IA non-small-cell lung cancers, recurrence is often observed. Hence, the aim of this study was to identify predictors of recurrence. Between 2005 and 2009, 138 patients with c-stage IA/p-stage IA non-small-cell lung cancers underwent resection. Recurrence and recurrence-free survival (RFS) were compared with clinical, radiographic and pathological findings. The 5-year cancer-specific survival rate was 97% and the RFS rate was 89% at a median follow-up time of 91 months. Recurrence was observed in 10 patients (7.2%). Significant differences were observed in RFS according to tumour dimensions on the mediastinal window image (>1.5 cm), serum carcinoembryonic antigen levels (>5.0 ng/mL), maximum standardised uptake values (SUVmax >2.5) and angiolymphatic invasion. Patients were grouped according to the number of risk factors for poor RFS. Patients with 0-1 of the identified risk factors had an RFS of 97%, where those with 2-4 factors had an RFS of 68% (p <0.001). Prognosis of patients exhibiting more than two of these risk factors is considerably poor. Thus, close observation and individualised adjuvant therapy may be beneficial to these patients.

Historical, the non-small cell lung cancer (NSCLC) was as a united disease entity and the chemotherapy to the metastatic cancer had limited results. Recent studies for the metastatic non-small cell lung cancer led to the ascertainment that the NSCLC does not constitute exclusively a disease entity, but different neoplasms guided from different molecular paths, different biological behavior and at extension requires different confrontation. Thus the new direction for the therapeutic approach of NSCLC is henceforth the most individualized approach based on the activated molecular paths of tumor. Distinct subtypes of NSCLC are driven by a specific genetic alteration, like EGFR, ALK, ROS1 or BRAF mutations, and these genetic alterations are sensitized to the inhibition of specific oncogenic pathways. The benefit from the use of tyrosine kinase inhibitors in patients with EGFR mutations it was confirmed by six randomized studies of phase III that investigated the role of gefitinib, erlotinib and afatinib. In these studies the response rates vary in the impressive percentages from 55% to 86% and were connected with a remarkable median progression free survival of approximately 8 to 13 months, and with better quality of life compared to that of chemotherapy. In early stages NSCLC is needed the individualization of systemic treatment in order to reduce toxicity that is observed in the classic chemotherapy and to impact outcome. The role of EGFR TKI's has been evaluated in the adjuvant chemotherapy in early stage resected NSCLC. The data from these studies suggest that adjuvant TKI therapy might not increase the overall survival, but delay the recurrences. Prospective trials restricted to EGFR or ALK driven NSCLC subsets potentially offering the opportunity for a definitive answer in early disease adjuvant setting (ALCHEMIST) or as induction treatment before stage III chemo-radiotherapy (RTOG 1210/Alliance 31101), are ongoing. Ongoing prospective trials may offer the

To evaluate the efficacy of using image-guided robotic stereotactic radioablation as an alternative treatment modality for patients with surgically resectable, but medically inoperable, T1 N0 M0, stage IA non-small cell lung cancer. Between January 2004 and May 2006, 19 patients, 11 women and 8 men ranging in age from 52 to 88 years, with stage IA non-small cell lung cancer were treated. Tumor volume ranged from 1.7 to 13 mL. Total doses ranged from 24 to 60 Gy delivered in 3 fractions. Eleven patients received 60 Gy. Real-time target localization was accomplished by radiographic detection of fiducial marker(s) implanted within the tumor combined with respiratory motion tracking. All patients tolerated radioablation well with fatigue as the main side effect. Fourteen patients are alive from 1 to 25 months posttreatment. Four patients died: 2 of comorbid disease and 2 of cancer progression (status post 60 and 55.5 Gy). Three patients developed grade I radiation pneumonitis. Two patients have stable disease. In 3 patients, cancer recurred in the planning treatment volume: in 2 patients after treatment with 60 Gy and in 1 patient after treatment with 55.5 Gy. One patient had local control in the target volume but developed metastasis to the ipsilateral hilum. Nine patients had a complete response and show no evidence of disease. In our early experience, stereotactic radioablation using the CyberKnife system appears to be a safe, minimally invasive, and effective modality for treating early stage lung cancer in patients with medically inoperable disease. Dose escalation and/or increasing the treatment volumes, with the aid of the high conformality of this technique, may help to achieve further improvements in these promising results.

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

DOE Office of Scientific and Technical Information (OSTI.GOV)

Hong, C; Ju, S; Ahn, Y

2015-06-15

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 directionalmore » 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.« less

Targeted therapies have markedly improved the management of patients with advanced non-small-cell lung cancer (NSCLC), but their efficacy in localized NSCLC is less well established. The aim of this review is to analyze trials of targeted therapies in localized NSCLC. In patients with wild-type EGFR, tyrosine kinase inhibitors have shown no efficacy in Phase III trials. Few data are available for EGFR-mutated localized NSCLC, as routine biological profiling is not recommended. Available studies are small, often retrospectives, and/or conducted in a single-center making it difficult to draw firm conclusions. Ongoing prospective Phase III trials are comparing adjuvant tyrosine kinase inhibitor administration versus adjuvant chemotherapy. By analogy with the indication of bevacizumab in advanced NSCLC, use of antiangiogenic agents in the perioperative setting is currently restricted to nonsquamous NSCLC. Several trials of adjuvant or neoadjuvant bevacizumab are planned or ongoing, but for the moment there is no evidence of efficacy. Data on perioperative use of biomarkers in early-stage NSCLC come mainly from small, retrospective, uncontrolled studies. Assessment of customized adjuvant or neoadjuvant therapy in localized NSCLC (with or without oncogenic driver mutations) is a major challenge. PMID:27462164

There have been significant advances in the understanding of the biology and treatment of non-small cell lung cancer (NSCLC) over the past few years. A number of molecularly targeted agents are in the clinic or in development for patients with advanced NSCLC (Table 1). We are beginning to understand the mechanisms of acquired resistance following exposure to tyrosine kinase inhibitors in patients with oncogene addicted NSCLC. The advent of next generation sequencing has enabled to study comprehensively genomic alterations in lung cancer. Finally, early results from immune checkpoint inhibitors are very encouraging. This review summarizes recent advances in the area of cancer genomics, targeted therapies and immunotherapy. PMID:25535693

Survival after diagnosis of lung cancer is poor and seemingly lower in the UK than other Western countries, due in large part to late presentation with advanced disease precluding curative treatment. Recent research suggests that around one-third of lung cancer patients reach specialist care after emergency presentation and have a worse survival outcome. Confirmation of these data and understanding which patients are affected may allow a targeted approach to improving outcomes. We used data from the UK National Lung Cancer Audit in a multivariate logistic regression model to quantify the association of non-elective referral in non-small cell lung cancer patients with covariates including age, sex, stage, performance status, co-morbidity and socioeconomic status and used the Kaplan-Meier method and Cox proportional hazards model to quantify survival by source of referral. In an analysis of 133,530 cases of NSCLC who presented 2006-2011, 19% of patients were referred non-electively (following an emergency admission to hospital or following an emergency presentation to A&E). This route of referral was strongly associated with more advanced disease stage (e.g. in Stage IV - OR: 2.34, 95% CI: 2.14-2.57, p<0.001) and worse performance status (e.g. in PS 4 - OR: 7.28, 95% CI: 6.75-7.86, p<0.001), but was also independently associated with worse socioeconomic status, and extremes of age. These patients were more likely to have died within 1 year of diagnosis (hazard ratio of 1.51 (95% CI: 1.49-1.54) after adjustment for key clinical variables. Our data confirm and quantify poorer survival in lung cancer patients who are referred non-electively to specialist care, which is more common in patients with poorer performance status, higher disease stage and less advantaged socioeconomic status. Work to tackle this late presentation should be urgently accelerated, since its realisation holds the promise of improved outcomes and better healthcare resource utilisation. Copyright �

The success of immune checkpoint inhibitors and the discovery of useful biomarkers to predict response to these agents is shifting much of the focus of personalized care for non-small cell lung cancer towards harnessing the immune response. With further advancement, more effective immunotherapy options will emerge along with more useful biomarkers. Paradoxically, minimally invasive small biopsy and cytology specimens have become the primary method for diagnosis of patients with advanced disease, as well for initial diagnosis and staging in earlier stage disease. For the benefit of these patients, we will continue to learn how to do more with less. In this perspective, we review aspects of immunobiology that underlie the current state of the art of existing and emerging immunologic biomarkers that hold potential to enhance the care of patients with non-small cell lung cancer. We address practical considerations for acquiring patient samples that accurately reflect disease immune status. We also propose a paradigm shift wherein the most important sample types that need to be proven in pioneering basic science and translation work and subsequent clinical trials are the specimens most often obtained clinically.

2018-01-01

Adjuvant platinum based chemotherapy is accepted as standard of care in stage II and III non-small cell lung cancer (NSCLC) patients and is often considered in patients with stage IB disease who have tumors ≥ 4 cm. The survival advantage is modest with approximately 5% at 5 years. Areas covered: This review article presents relevant data regarding chemotherapy use in the perioperative setting for early stage NSCLC. A literature search was performed utilizing PubMed as well as clinical trial.gov. Randomized phase III studies in this setting including adjuvant and neoadjuvant use of chemotherapy as well as ongoing trials on targeted therapy and immunotherapy are also discussed. Expert commentary: With increasing utilization of screening computed tomography scans, it is possible that the percentage of early stage NSCLC patients will increase in the coming years. Benefits of adjuvant chemotherapy in early stage NSCLC patients remain modest. There is a need to better define patients most likely to derive survival benefit from adjuvant therapy and spare patients who do not need adjuvant chemotherapy due to the toxicity of such therapy. Trials for adjuvant targeted therapy, including adjuvant EGFR-TKI trials and trials of immunotherapy drugs are ongoing and will define the role of these agents as adjuvant therapy.

Background: The frequency of ROS1 rearrangement in non-small cell lung cancers has been reported from 1.6% to 2.3%. Materials and Methods: We examined 105 lung adenocarcinoma patients for ROS1 rearrangement which were negative for EGFR and anaplastic lymphoma kinase. Clinical characteristics of ROS1 rearranged patients and their responses to crizotinib therapy were studied. Results: Of the 105 patients, three cases were positive for ROS1 rearrangement by fluorescence in situ hybridization analysis. All of them showed heterogeneous pattern. All the 3 ROS1-positive patients were females in their forties and started on crizotinib. All of them responded to treatment. One of them developed resistance after 3 months. Another one showed marked systemic response but central nervous system lesions progressed. The third case is doing well till date with inactive lesions on positron emission tomography scan. Conclusions: The frequency of ROS1 rearrangement is low in non-small cell lung carcinoma, but their diagnosis offers patients an opportunity to receive highly effective targeted therapies.

Bavituximab is a phosphatidylserine (PS)-targeting monoclonal antibody with immune-modulating and tumor-specific vascular targeting properties. Preclinical studies have shown activity against numerous solid tumors and at least an additive effect in combination with chemotherapy. This study evaluated bavituximab in combination with paclitaxel and carboplatin in patients with previously untreated, locally advanced or metastatic non-small-cell lung cancer (NSCLC). This phase II, open-label study (NCT00687817) was conducted in 49 patients with stage IIIB/IV NSCLC utilizing a Simon two-stage design. Patients were treated with up to six cycles of carboplatin area under the concentration-time curve (AUC) 5 plus paclitaxel 175 mg/m2 every 21 days with weekly bavituximab 3 mg/kg followed by bavituximab monotherapy until progression or unacceptable toxicity. The primary efficacy endpoint of overall response rate (ORR) was 40.8% (complete response [CR] 2.0%, partial response [PR] was 38.8%). Median progression-free survival (PFS) and overall survival (OS) were 6.0 and 12.4 months, respectively. Treatment-related adverse events (AEs) occurred in 40.8% of patients. The most common treatment-related AEs were anemia (10.2%), asthenia, vomiting, paresthesia, anorexia, and fatigue (6.1% each). One patient with a central, cavitating squamous tumor developed fatal hemoptysis and aspiration. Bavituximab in combination with paclitaxel-carboplatin as first-line therapy demonstrated a tolerable safety profile and potential efficacy in this single-arm phase II trial in patients with advanced local or metastatic NSCLC. Randomized trials with this regimen are in progress. NCT00687817. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Atezolizumab: A Review in Previously Treated Advanced Non-Small Cell Lung Cancer.

PubMed

Blair, Hannah A

2018-05-21

Atezolizumab (TECENTRIQ™), an immune checkpoint inhibitor, is an immunoglobulin G1 monoclonal antibody that binds to programmed death ligand 1 (PD-L1) and blocks its interactions with programmed death 1 and B7.1 receptors. Atezolizumab is approved as monotherapy in several countries worldwide for the treatment of patients with advanced non-small cell lung cancer (NSCLC) who have previously received chemotherapy. Approval was based on its clinical benefit in this setting in the phase II POPLAR and phase III OAK trials. In these studies, atezolizumab significantly prolonged overall survival (OS) relative to docetaxel, regardless of PD-L1 status. Increasing PD-L1 expression was associated with OS improvements. Atezolizumab also demonstrated efficacy in the phase II FIR and BIRCH trials, as assessed by objective response rates (ORRs) in patients with tumours expressing PD-L1. Higher ORRs were seen in patients with high PD-L1 expression. Atezolizumab had an acceptable, manageable tolerability profile, with a low incidence of immune-related adverse events. Therefore, atezolizumab is a valuable treatment option for patients with advanced NSCLC that has progressed during or after chemotherapy.

Purpose: To update the Allegheny General Hospital experience of high-risk Stage I non-small-cell lung cancer patients treated with sublobar resection and intraoperative {sup 125}I Vicryl mesh brachytherapy. Methods and Materials: Between January 5, 1996 and February 19, 2008, 145 patients with Stage I non-small-cell lung cancer who were not lobectomy candidates because of cardiopulmonary compromise underwent sublobar resection and placement of {sup 125}I seeds along the resection line. The {sup 125}I seeds embedded in Vicryl suture were attached with surgical clips to a sheet of Vicryl mesh, inserted over the target area, and prescribed to a 0.5-cm planar margin. Results:more » The mean target area, total activity, number of seeds implanted, and prescribed total dose was 33.3 cm{sup 2} (range, 18.0-100.8), 20.2 mCi (range, 11.1-29.7), 46 (range, 30-100), and 117 Gy (range, 80-180), respectively. The median length of the surgical stay was 6 days (range, 1-111), with a perioperative mortality rate of 3.4%. At a median follow-up of 38.3 months (range, 1-133), 6 patients had developed local recurrence (4.1%), 9 had developed regional failure (6.2%), and 25 had distant failure (17.2%). On multivariate analysis, no patient- or tumor-specific factors or surgical or dosimetric factors were predictive of local recurrence. The overall median survival was 30.5 months with a 3- and 5-year overall survival rate of 65% and 35%, respectively. Conclusion: {sup 125}I brachytherapy for high-risk, Stage I non-small-cell lung cancer after sublobar resection is well tolerated and associated with a low local failure rate.« less

Purpose: Although curative resection is expected to be effective in patients with clinical (c-) stage IA/pathological (p-) stage IA non-small-cell lung cancers, recurrence is often observed. Hence, the aim of this study was to identify predictors of recurrence. Methods: Between 2005 and 2009, 138 patients with c-stage IA/p-stage IA non-small-cell lung cancers underwent resection. Recurrence and recurrence-free survival (RFS) were compared with clinical, radiographic and pathological findings. Results: The 5-year cancer-specific survival rate was 97% and the RFS rate was 89% at a median follow-up time of 91 months. Recurrence was observed in 10 patients (7.2%). Significant differences were observed in RFS according to tumour dimensions on the mediastinal window image (>1.5 cm), serum carcinoembryonic antigen levels (>5.0 ng/mL), maximum standardised uptake values (SUVmax >2.5) and angiolymphatic invasion. Patients were grouped according to the number of risk factors for poor RFS. Patients with 0–1 of the identified risk factors had an RFS of 97%, where those with 2–4 factors had an RFS of 68% (p <0.001). Conclusion: Prognosis of patients exhibiting more than two of these risk factors is considerably poor. Thus, close observation and individualised adjuvant therapy may be beneficial to these patients.

The 21st century has seen several paradigm shifts in the treatment of non-small cell lung cancer (NSCLC) in early-stage inoperable disease, definitive locally advanced disease, and the postoperative setting. A key driver in improvement of local disease control has been the significant evolution of radiation therapy techniques in the last three decades, allowing for delivery of definitive radiation doses while limiting exposure of normal tissues. For patients with locally-advanced NSCLC, the advent of volumetric imaging techniques has allowed a shift from 2-dimensional approaches to 3-dimensional conformal radiation therapy (3DCRT). The next generation of 3DCRT, intensity-modulated radiation therapy and volumetric-modulated arc therapy (VMAT), have enabled even more conformal radiation delivery. Clinical evidence has shown that this can improve the quality of life for patients undergoing definitive management of lung cancer. In the early-stage setting, conventional fractionation led to poor outcomes. Evaluation of altered dose fractionation with the previously noted technology advances led to advent of stereotactic body radiation therapy (SBRT). This technique has dramatically improved local control and expanded treatment options for inoperable, early-stage patients. The recent development of proton therapy has opened new avenues for improving conformity and the therapeutic ratio. Evolution of newer proton therapy techniques, such as pencil-beam scanning (PBS), could improve tolerability and possibly allow reexamination of dose escalation. These new progresses, along with significant advances in systemic therapies, have improved survival for lung cancer patients across the spectrum of non-metastatic disease. They have also brought to light new challenges and avenues for further research and improvement. PMID:28529896

In the past decade, a shift toward targeted therapies in non-small-cell lung cancer following molecular profiling has dramatically changed the way advanced adenocarcinoma is treated. However, tumor cells inevitably acquire resistance to such therapies, circumventing any sustained clinical benefit. As the genomic classification of lung cancer continues to evolve and as the mechanisms of acquired resistance to targeted therapies become elucidated and more improved target-specific drugs come into sight, the future will see more promising results from the clinic through the development of new therapeutic strategies to overcome, or prevent the development of, resistance for lung cancer patients.

Non-small-cell lung cancer (NSCLC) is a disseminated disease in 50% of cases, with a gloomy prognosis and median survivals of < 1 year. Based on substantial advances, cancer biology insights and novel biotechnology tools, customized treatment provides hints that cisplatin-based treatment can be optimized in favorable subgroups of patients according to gene expression DNA repair profiles. In 2004, it was discovered that 10-15% of NSCLC can harbor a new class of EGFR mutation conferring specific sensitivity to EGFR tyrosine kinase inhibitors. The homologous recombination pathway provides information for customizing cisplatin-based chemotherapy. BRCA1 plays a central role in this pathway that can be used in tailoring chemotherapy. Patient subgroups can obtain significant increases in progression-free survival. For EGFR lung-addicted cancers, treatment with EGFR tyrosine kinase inhibitors like erlotinib provide impressive improvement in progression-free survival--up to 14 months with significant enhanced survival. Customized chemotherapy based on BRCA1 models can contribute to demonstrating this approach's clinical relevance, and the implementation of EGFR mutation assessment is warranted to identify EGFR-addicted lung cancers with a different prognosis that could benefit from a specifically targeted therapy approach.

The primary objective of this study was to evaluate the safety and tolerability of carboplatin plus pemetrexed for elderly patients (≥75 years) with chemotherapy-naïve advanced non-squamous non-small cell lung cancer. Patients received escalated doses of carboplatin at an area under the concentration-time curve of 4 (Level 1) or 5 (Level 2) plus pemetrexed (500 mg/m(2)) every 3 weeks for a maximum of six cycles. Dose escalation was decided according to whether dose-limiting toxicity occurred in the first cycle of chemotherapy. A total of 20 patients (6 at Level 1, 14 at Level 2) were enrolled. No dose-limiting toxicities were observed in patients at Level 1 or the first six patients at Level 2, and therefore the combination of carboplatin at an area under the concentration-time curve of 5 plus pemetrexed at 500 mg/m(2) was considered to be the recommended dose. Among a total of 14 patients in Level 2, only 1 patient experienced dose-limiting toxicity: Grade 3 febrile neutropenia and urticaria. The major toxicities were neutropenia, thrombocytopenia and anemia. Liver dysfunction, fatigue and anorexia were also common, but generally manageable. Six patients showed partial responses, giving the overall response rate of 30%. The median progression-free survival period was 4.8 months (95% confidence interval 2.9-6.7 months). The combination of carboplatin at an area under the concentration-time curve of 5 plus pemetrexed at 500 mg/m(2) was determined as the recommended dose in chemotherapy-naïve elderly patients (≥75 years) with advanced non-squamous non-small cell lung cancer, in view of overall safety and tolerability.

Although ~20% of human cancers are caused by microorganisms, only suspicion exists for a microbial cause of lung cancer. Potential infectious agents were investigated in non-small cell lung cancer (NSCLC) and non-neoplastic lung. Seventy NSCLC tumours (33 squamous cell carcinomas, 17 adenocarcinomas, 10 adenocarcinomas with lepidic spread, and 10 oligometastases) and 10 non-neoplastic lung specimens were evaluated for molecular evidence of microorganisms. Tissues were subjected to the Lawrence Livermore Microbial Detection Array, an oncovirus panel of the International Agency for Research on Cancer, and human papillomavirus (HPV) genotyping. Associations were examined between microbial prevalence, clinical characteristics, and p16 and EGFRmore » expression. Retroviral DNA was observed in 85% squamous cell carcinomas, 47% adenocarcinomas, and 10% adenocarcinomas with lepidic spread. Human papillomavirus DNA was found in 69% of squamous cell carcinomas with 30% containing high-risk HPV types. No significant viral DNA was detected in non-neoplastic lung. Patients with tumours containing viral DNA experienced improved long-term survival compared with patients with viral DNA-negative tumours. Lastly, most squamous cell carcinomas and adenocarcinomas contained retroviral DNA and one-third of squamous cell carcinomas contained high-risk HPV DNA. Viral DNA was absent in non-neoplastic lung.

Stereotactic radiotherapy (SRT) has recently been used for the treatment of small lung tumors. We retrospectively evaluated the efficacy and safety of SRT for non-small cell lung cancer (NSCLC) treated in our hospital. Between October 2007 and December 2009, 31 tumors of 29 patients were treated by SRT (mean age, 75 years: stage IA, n=13; stage IB, n=5; stage IIIA, n=1; stage IIIB, n=1; recurrence, n=11). All of the patients completed the treatment. In one patient who had radiation pneumonitis before SRT, a progression of pulmonary fibrosis was observed, and treated with steroid therapy. In evaluable 29 tumors of 27 patients, the recurrence rates are 11/29 (37.9%). Median progression free survival time was 8 months. The recurrence rate and median progression free survival time of stage IA and IB subgroups were 4/17 (23.5%) and 12 months, respectively. SRT is thought to be a safe and effective treatment for stage I NSCLC. For patients with stage I NSCLC, SRT can be a complemental therapy for surgical resection.

The immune system can restrain or promote cancer development and growth. Antibodies targeting immune checkpoints have revolutionized cancer treatment. Among the best responses have been in non-small cell lung cancer (NSCLC) which is largely caused by chronic exposure to carcinogens; associated with high neoantigen creation and sensitization to immune recognition. Atezolizumab was the first approved antibody that targets the PD-1 ligand (PD-L1). Areas covered: This drug profile article covers the basics of the cancer-immunity cycle and reviews some aspects of innate and adaptive immunology. We discuss the discovery of PD-L1 and PD-L2 while highlight the potential differences in targeting PD-L1 versus PD-1. In addition, we briefly summarized the available pre-clinical and clinical data of atezolizumab use in NSCLC. A special section covers the challenges of PD-L1 immunohistochemistry assay. Expert commentary: PD-1:PD-L1 blockade has taken the lead in the immunotherapeutics field and represents the backbone of developing combination immunotherapies. Atezolizumab represents a step forward in the treatment of advanced NSCLC, nonetheless PD1:PD-L1 blockade in early-stage lung cancer is still a matter of debate.

We hypothesized that the increased percentages of Regulatory T (Treg) cells, as well as over expression of Cytotoxic T Lymphocyte Antigen-4 (CTLA-4) by lymphocyte subsets might be associated with lung cancer. Accordingly, peripheral blood of 23 new cases with non-small cell lung cancer (NSCLC) and 16 healthy volunteers were investigated, by follow cytometry, for the prevalence of CD4+CD25+FoxP3+ Treg cells as well as surface (sur-) and intracellular (In-) expression of CTLA-4 by the main lymphocyte subsets (CD4+, CD8+ and CD19+). Results indicated that NSCLC patients had an increased percentage of Treg cells than controls (7.9±4.1 versus 3.8±1.8, P=0.001). The proportion of Treg cells was observed to be increased by stage increase in patients (stage II=5.2±2.4, stage III=7.9±4.4, stage IV=12.0±2.2), and also significantly higher in metastatic than non-metastatic stages (12.0±2.2 versus 6.8±3.9, P=0.023). Increase of SurCTLA-4- as well as InCTLA-4-expressing lymphocytes in patients were observed in nearly all investigated subsets, but significant differences between patients and controls were observed about InCTLA-4+CD4+ lymphocytes (8.6±7.1 and 3.8±5.3 respectively, P=0.006) as well as SurCTLA-4+CD8+ lymphocytes (0.3±0.2 and 0.2±0.1 respectively, P=0.047). In conclusion, the results suggest that immunotherapy regimen targeting CTLA-4 and Treg cells might be beneficial in lung cancer patients. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Programmed cell death ligand (PD-L1) has been studied as a predictive immunotherapy biomarker. We investigated PD-L1 expression in the whole tumor and in tumor-infiltrating macrophages (TIMs) as a prognostic biomarker in surgically resected pathologic stage I non-small cell lung cancer. Pathologic specimen from 113 patients with stage I lung cancer (pT1-2a, N0, M0, tumor size 1-5 cm, 79 adenocarcinoma, 34 squamous cell carcinoma) were analyzed for PD-L1 expression in the tumor and in the TIMs using immunohistochemistry and image analysis. Statistics included recursive partitioning, univariable, multivariable, and Kaplan-Meier analyses. Patients whose tumors expressed <4.7% PD-L1 (N = 87) experienced significantly better overall survival (OS) (P = 0.001) than patients with PD-L1 >4.7% (N = 26). Patients with PD-L1 expression in macrophages <6.3% (N = 24) also experienced significantly better (P = 0.005) OS than patients with >6.3% (N = 89). The best outcomes were observed in patients with low PD-L1 expression in both tumor and macrophages with 5-year OS of 94% (N = 17). Contrarily, patients with high PD-L1 expression in both tumor and macrophages experienced 5-year OS of 20% (N = 19). Low PD-L1 expression in the tumor and in the TIMs was independently associated with survival in multivariable analysis (P = 0.000 and P = 0.030, respectively). Lower PD-L1 % expression in the tumor and in the TIMs seems to be associated with significantly better OS in surgically resected stage I lung cancer. Additional studies are needed to validate PD-L1 as a prognostic biomarker in lung cancer and to study the mechanisms of intratumoral immune response. Copyright © 2017 Elsevier Inc.

Epidermal growth factor receptor (EGFR) mutation is an important predictor for response to personalized treatments of patients with advanced non-small-cell lung cancer (NSCLC). However its usage is limited due to the difficult of obtaining tissue specimens. A novel prediction system using matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) has been reported to be a perspective tool in European countries to identify patients who are likely to benefit from EGFR tyrosine kinase inhibitor (TKI) treatment. In the present study, MALDI-TOF MS was used on pretreatment serum samples of patients with advanced non-small-cell lung cancer to discriminate the spectra between disease control and disease progression groups in one cohort of Chinese patients. The candidate features for classification were subsequently validated in a blinded fashion in another set of patients. The correlation between plasma EGFR mutation status and the intensities of representative spectra for classification was evaluated. A total of 103 patients that were treated with EGFR-TKIs were included. It was determined that 8 polypeptides peaks were significant different between the disease control and disease progression group. A total of 6 polypeptides were established in the classification algorithm. The sensitivity of the algorithm to predict treatment responses was 76.2% (16/21) and the specificity was 81.8% (18/22). The accuracy rate of the algorithm was 79.1% (34/43). A total of 3 polypeptides were significantly correlated with EGFR mutations (P=0.04, P=0.03 and P=0.04, respectively). The present study confirmed that MALDI-TOF MS analysis can be used to predict responses to EGFR-TKI treatment of the Asian population where the EGFR mutation status differs from the European population. Furthermore, the expression intensities of the three polypeptides in the classification model were associated with EGFR mutation. PMID:29844828

Mechanisms of tumor immune surveillance and immune escape have been recently elucidated and led to the development of a new therapeutic field in oncology, that of immunotherapy. Immunotherapy aims to reactivate the immune system against cancer. Neoplasias like non-small cell lung cancer (NSCLC) are of particular interest and clinical studies with immunotherapeutic agents have shown significant survival benefit. Several agents have gained corresponding regulatory approvals. In particular, nivolumab, pembrolizumab and atezolizumab have been approved for second-line treatment of NSCLC, pembrolizumab is the only immune checkpoint inhibitor that has been approved in the first-line treatment and durvalumab is approved in the locally advanced disease. In this review, we aim to present the implementation of immunotherapy in the treatment of advanced NSCLC. We will discuss not only the approved regimens but also the future perspectives, the serious adverse events such as hyperprogression and the possible predictive markers that will aid the selection of the patients that will benefit from immunotherapy.

The black population remains underrepresented in clinical trials despite reports suggesting greater incidence and deaths from locally advanced non-small cell lung cancer (NSCLC). We determined outcomes for black and non-black patients in a well-annotated cohort treated with either definitive chemoradiation (CRT; bimodality) or CRT followed by surgery (trimodality therapy). A retrospective analysis of 355 stage III NSCLC patients treated with curative intent at the University of Maryland, Medical Center, between January 2000-December 2013 was performed. The Kaplan-Meier approach and the Cox proportional hazards models were used to analyze overall survival (OS) and freedom-from-recurrence (FFR) in black and non-black patients. The chi-square test was used to compare categorical variables. Black patients comprised 42% of the cohort and were more likely to be younger (p<0.0001), male (p=0.030), single (p<0.0001), reside in lower household income zipcodes (p<0.0001), have an Eastern Cooperative Oncology Group (ECOG) performance status >0 (p<0.001), and less likely to undergo surgery (p<0.0001). With a median follow-up of 15 months for all patients and 89 months for surviving patients (range:1-186 months), median OS times for black and non-black patients were 22 and 24 months, respectively (p=0.698). FFR rates were also comparable between the two groups (p=0.468). Surgery improved OS in both cohorts. Race was not a significant predictor for OS or FFR even when adjusted for other factors. We found similar oncologic outcomes in black and non-black NSCLC patients when treated with curative intent in a comprehensive cancer center setting, despite epidemiologic differences in presentation and receipt of care. Future efforts to improve outcomes in black patients could focus on addressing modifiable social disparities. Copyright © 2017. Published by Elsevier B.V.

To observe the clinical efficacy and adverse effects of taxol plus carboplatin (TP) or gemcitabine plus carboplatin (GP) in patients with advanced non-small-cell lung carcinoma. A total of 86 patients with advanced non-small-cell lung carcinoma with a histologically confirmed diagnosis at our department were treated with at least two cycles of drug therapy according to the WHO standard. There were 43 cases in TP group and 43 cases in GP group. TP group: taxol 150 mg/m(2), d1, carboplatin 300 mg/m(2) in d1; GP group: gemcitabine 1000 mg/m(2), 30 min, d1, 8, carboplatin 300 mg/m(2) in d1, 3 weeks a cycle. The efficacy and side effects were analyzed after two cycles of chemotherapy. When TP and GP groups were compared, the effective rate was 44.2% vs 39.5%; disease control rate (CR + PR + SD): 81.4% vs 74.4%; median time to progress (TTP): 4.6 vs 4.5 months; medium survivals: 8.6 vs 8.8 months; 1-year survival rates: 17.2% vs 18.1%; 2-year survival rates: 8% vs 10%. The statistic analysis showed that the two groups had no significant difference. The main cytotoxicities of GP and TP groups were predominantly thrombocytopenia and leucopenia respectively. The two groups had no significant statistical difference. The incidences of allergen, alopecia and peripheral neurotoxicity were higher in the TP group. The two groups had statistical difference. Tolerance was excellent in both groups. The therapeutic effect and tolerance are excellent for advanced non-small cell lung carcinoma. The efficacy and survival rate of two groups show no statistical difference.

To assess the expected costs and outcomes of alternative strategies for staging of lung cancer to inform a Danish National Health Service perspective about the most cost-effective strategy. A decision tree was specified for patients with a confirmed diagnosis of non-small-cell lung cancer. Six strategies were defined from relevant combinations of mediastinoscopy, endoscopic or endobronchial ultrasound with needle aspiration, and combined positron emission tomography-computed tomography with F18-fluorodeoxyglucose. Patients without distant metastases and central or contralateral nodal involvement (N2/N3) were considered to be candidates for surgical resection. Diagnostic accuracies were informed from literature reviews, prevalence and survival from the Danish Lung Cancer Registry, and procedure costs from national average tariffs. All parameters were specified probabilistically to determine the joint decision uncertainty. The cost-effectiveness analysis was based on the net present value of expected costs and life years accrued over a time horizon of 5 years. At threshold values of around €30,000 for cost-effectiveness, it was found to be cost-effective to send all patients to positron emission tomography-computed tomography with confirmation of positive findings on nodal involvement by endobronchial ultrasound. This result appeared robust in deterministic sensitivity analysis. The expected value of perfect information was estimated at €52 per patient, indicating that further research might be worthwhile. The policy recommendation is to make combined positron emission tomography-computed tomography and endobronchial ultrasound available for supplemental staging of patients with non-small-cell lung cancer. The effects of alternative strategies on patients' quality of life, however, should be examined in future studies.

To identify the variability of short- and long-term survival outcomes among closed Phase III randomized controlled trials with small sample sizes comparing SBRT (stereotactic body radiation therapy) and surgical resection in operable clinical Stage I non-small cell lung cancer (NSCLC) patients. Clinical Stage I NSCLC patients who underwent surgery at our institution meeting the inclusion/exclusion criteria for STARS (Randomized Study to Compare CyberKnife to Surgical Resection in Stage I Non-small Cell Lung Cancer), ROSEL (Trial of Either Surgery or Stereotactic Radiotherapy for Early Stage (IA) Lung Cancer), or both were identified. Bootstrapping analysis provided 10,000 iterations to depict 30-day mortality and three-year overall survival (OS) in cohorts of 16 patients (to simulate the STARS surgical arm), 27 patients (to simulate the pooled surgical arms of STARS and ROSEL), and 515 (to simulate the goal accrual for the surgical arm of STARS). From 2000 to 2012, 749/873 (86%) of clinical Stage I NSCLC patients who underwent resection were eligible for STARS only, ROSEL only, or both studies. When patients eligible for STARS only were repeatedly sampled with a cohort size of 16, the 3-year OS rates ranged from 27 to 100%, and 30-day mortality varied from 0 to 25%. When patients eligible for ROSEL or for both STARS and ROSEL underwent bootstrapping with n=27, the 3-year OS ranged from 46 to 100%, while 30-day mortality varied from 0 to 15%. Finally, when patients eligible for STARS were repeatedly sampled in groups of 515, 3-year OS narrowed to 70-85%, with 30-day mortality varying from 0 to 4%. Short- and long-term survival outcomes from trials with small sample sizes are extremely variable and unreliable for extrapolation. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

McGarry, Ronald C.; Papiez, Lech; Williams, Mark

Purpose: A Phase I dose escalation study of stereotactic body radiation therapy to assess toxicity and local control rates for patients with medically inoperable Stage I lung cancer. Methods and Materials: All patients had non-small-cell lung carcinoma, Stage T1a or T1b N0, M0. Patients were immobilized in a stereotactic body frame and treated in escalating doses of radiotherapy beginning at 24 Gy total (3 x 8 Gy fractions) using 7-10 beams. Cohorts were dose escalated by 6.0 Gy total with appropriate observation periods. Results: The maximum tolerated dose was not achieved in the T1 stratum (maximum dose = 60 Gy),more » but within the T2 stratum, the maximum tolerated dose was realized at 72 Gy for tumors larger than 5 cm. Dose-limiting toxicity included predominantly bronchitis, pericardial effusion, hypoxia, and pneumonitis. Local failure occurred in 4/19 T1 and 6/28 T2 patients. Nine local failures occurred at doses {<=}16 Gy and only 1 at higher doses. Local failures occurred between 3 and 31 months from treatment. Within the T1 group, 5 patients had distant or regional recurrence as an isolated event, whereas 3 patients had both distant and regional recurrence. Within the T2 group, 2 patients had solitary regional recurrences, and the 4 patients who failed distantly also failed regionally. Conclusions: Stereotactic body radiation therapy seems to be a safe, effective means of treating early-stage lung cancer in medically inoperable patients. Excellent local control was achieved at higher dose cohorts with apparent dose-limiting toxicities in patients with larger tumors.« less

Understanding the drug development pathway is critical for streamlining the development of effective cancer treatments. The objective of the current study was to delineate the drug development timeline and attrition rate of different drug classes for common cancer disease sites. Drugs entering clinical trials for breast, colorectal, and non-small cell lung cancer were identified using a pharmaceutical business intelligence database. Data regarding drug characteristics, clinical trials, and approval dates were obtained from the database, clinical trial registries, PubMed, and regulatory Web sites. A total of 411 drugs met the inclusion criteria for breast cancer, 246 drugs met the inclusion criteria for colorectal cancer, and 315 drugs met the inclusion criteria for non-small cell lung cancer. Attrition rates were 83.9% for breast cancer, 87.0% for colorectal cancer, and 92.0% for non-small cell lung cancer drugs. In the case of non-small cell lung cancer, there was a trend toward higher attrition rates for targeted monoclonal antibodies compared with other agents. No tumor site-specific differences were noted with regard to cytotoxic chemotherapy, immunomodulatory, or small molecule kinase inhibitor drugs. Drugs classified as "others" in breast cancer had lower attrition rates, primarily due to the higher success of hormonal medications. Mean drug development times were 8.9 years for breast cancer, 6.7 years for colorectal cancer, and 6.6 years for non-small cell lung cancer. Overall oncologic drug attrition rates remain high, and drugs are more likely to fail in later-stage clinical trials. The refinement of early-phase trial design may permit the selection of drugs that are more likely to succeed in the phase 3 setting.

The present study aimed to investigate the association between the expression of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) long non-coding RNA (lncRNA) and the recurrence of non-small cell lung cancer (NSCLC) and to elucidate the potential mechanisms of MALAT1 in vitro . Between 1 June 1, 2010 and December 30, 2016, NSCLC tumor tissues and adjacent non-cancerous tissues were obtained from 120 patients with NSCLC, who had undergone surgical resection at Taizhou Hospital of Wenzhou Medical University (Linhai, China). The total RNA of tissues and cells were extracted and the expression of MALAT1 was determined using a wound healing assay and reverse transcription quantitative polymerase chain reaction. In addition, MALAT1 expression in A549 cells was silenced using small interfering RNA. The proliferation, migration and invasion of cells were then assessed using a CellTiter 96 kit and Transwell assays. MALAT1 expression was significantly increased in NSCLC samples compared with expression in adjacent non-cancerous tissues. Furthermore, the expression of MALAT1 in patients with NSCLC that exhibited recurrence was markedly higher than in those that did not. The results of the present study also demonstrated significant associations between high expression of MALAT1 and female sex, Tumor-Node-Metastasis advanced stage, vessel invasion, pathological differentiation and recurrence of patients with NSCLC. The proliferative, migratory and invasive abilities of MALAT1-silenced A549 cells were significantly decreased compared with those of control cells. MALAT1 expression was significantly increased in NSCLC tissues and was revealed to serve a role in the progression of NSCLC.

Induction therapy leads to significant improvement in survival for selected patients with stage IIIA non-small cell lung cancer. The ideal time interval between induction therapy and surgery remains unknown. Clinical stage IIIA non-small cell lung cancer patients receiving induction therapy and surgery were identified in the National Cancer Database. Delayed surgery was defined as greater than or equal to 3 months after starting induction therapy. A logistic regression model identified variables associated with delayed surgery. Cox proportional hazards modeling and Kaplan-Meier analysis were performed to evaluate variables independently associated with overall survival. From 2006 to 2010, 1,529 of 2,380 (64.2%) received delayed surgery. Delayed surgery patients were older (61.2 ± 10.0 years versus 60.3 ± 9.2; p = 0.03), more likely to be non-white (12.4% versus 9.7%; p = 0.046), and less likely to have private insurance (50% versus 58.2%; p = 0.002). Delayed surgery patients were also more likely to have a sublobar resection (6.3% versus 2.9%). On multivariate analysis, age greater than 68 years (odds ratio [OR], 1.37; 95% confidence interval [CI], 1.1 to 1.7) was associated with delayed surgery, whereas white race (OR, 0.75; 95% CI, 0.57 to 0.99) and private insurance status (OR, 0.82; 95% CI, 0.68 to 0.99) were associated with early surgery. Delayed surgery was associated with higher risk of long-term mortality (hazard ratio, 1.25; 95% CI, 1.07 to 1.47). Delayed surgery after induction therapy for stage IIIA lung cancer is associated with shorter survival, and is influenced by both social and physiologic factors. Prospective work is needed to further characterize the relationship between patient comorbidities and functional status with receipt of timely surgery.

Dacomitinib is an irreversible pan-EGFR family tyrosine kinase inhibitor. Findings from a phase 2 study in non-small cell lung cancer showed favourable efficacy for dacomitinib compared with erlotinib. We aimed to compare dacomitinib with erlotinib in a phase 3 study. In a randomised, multicentre, double-blind phase 3 trial in 134 centres in 23 countries, we enrolled patients who had locally advanced or metastatic non-small-cell lung cancer, progression after one or two previous regimens of chemotherapy, Eastern Cooperative Oncology Group (ECOG) performance status of 0-2, and presence of measurable disease. We randomly assigned patients in a 1:1 ratio to dacomitinib (45 mg/day) or erlotinib (150 mg/day) with matching placebo. Treatment allocation was masked to the investigator, patient, and study funder. Randomisation was stratified by histology (adenocarcinoma vs non-adenocarcinoma), ethnic origin (Asian vs non-Asian and Indian sub-continent), performance status (0-1 vs 2), and smoking status (never-smoker vs ever-smoker). The coprimary endpoints were progression-free survival per independent review for all randomly assigned patients, and for all randomly assigned patients with KRAS wild-type tumours. The study has completed accrual and is registered with ClinicalTrials.gov, number NCT01360554. Between June 22, 2011, and March 12, 2013, we enrolled 878 patients and randomly assigned 439 to dacomitinib (256 KRAS wild type) and 439 (263 KRAS wild type) to erlotinib. Median progression-free survival was 2·6 months (95% CI 1·9-2·8) in both the dacomitinib group and the erlotinib group (stratified hazard ratio [HR] 0·941, 95% CI 0·802-1·104, one-sided log-rank p=0·229). For patients with wild-type KRAS, median progression-free survival was 2·6 months for dacomitinib (95% CI 1·9-2·9) and erlotinib (95% CI 1·9-3·0; stratified HR 1·022, 95% CI 0·834-1·253, one-sided p=0·587).

Objective: To evaluate the safety and efficacy of icotinib as first-line therapy in Chinese non-small cell lung cancer (NSCLC) patients harboring epidermal growth factor receptor (EGFR) sensitive mutations. Methods: Patients with stage ⅢB/Ⅳ NSCLC who had EGFR sensitive mutation and had no previous treatment were enrolled into this study. The response rates, progress free survival (PFS), overall survival (OS), and the safety were analyzed. Results: Ninety advanced adenocarcinoma patients were enrolled in this study, 44 patients had partial response (PR), 42 patients had stable disease (SD), 4 patients had progressive disease (PD), with an overall response rate (ORR) of 48.9%, and a disease control rate (DCR) of 95.6%. The median PFS was 14.9 months (95% CI 13.5-16.3) and the OS was 37.0 weeks (95% CI 27.9-46.1). Patients with brain metastases showed higher ORR( P =0.049). Patients with stage ⅢB had longer PFS than those with stage Ⅳ( P =0.007). The most common adverse events were grade 1-2 skin rash (38 patients, 40.9%). Other adverse events included dry skin, oral mucositis, diarrhea and liver function injury. Three patients withdrew because of severe liver injury or skin rash. No treatment related mortality occurred. Conclusions: Icotinib is effective and safe as first-line treatment for Chinese advanced NSCLC patients with EGFR sensitive mutation.

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

Background To evaluate the efficacy and safety of Icotinib – an orally administered, highly potent selective inhibitor of epidermal growth factor receptor (EGFR) and its active mutations, in the treatment of patients with advanced non-small cell lung cancer (NSCLC). Methods A total of 101 patients with stage IIIb/IV NSCLC were treated with 125 mg Icotinib three times a day until disease progression or intolerable toxicity. Response rate was evaluated using response evaluation criteria in solid tumors and progression-free survival (PFS) was collected. Results The overall response rate (ORR) and disease control rate (DCR) were 37.6% (38/101) and 79.2% (80/101), respectively. The median PFS was 6.5 months. Multivariate analysis showed that female gender (P= 0.048, 95% confidence interval [CI] 1.010–6.016) and occurrence of rash (P= 0.002, 95% CI 1.667–9.809) were the independent predictive factors for ORR, while a performance status (PS) score of 0–1 (P= 0.001, 95% CI 0.024–0.402) and rash (P= 0.042, 95% CI 1.089–76.557) were the independent predictive factors for DCR. In addition, PS scores of 0–1 (P <0.001, 95% CI 0.135–0.509), and non-smoking (P= 0.017, 95% CI 0.342–0.900) were found to be independent influencing factors for PFS. Moreover, patients with EGFR mutations had better PFS than patients with wild type EGFR, while patients with EGFR exon 19 deletion had better survival than those with EGFR exon 21 mutation. The most common adverse effects of Icotinib were rash (35.6%) and diarrhea (17.8%), which was tolerable. Conclusion Treatment of stage IIIb/IV NSCLC patients with Icotinib was effective and tolerable, specifically in patients with EGFR mutation. PMID:26767007

The aim of this study was to investigate the association between the presence of lymphatic vessel invasion (LVI) in primary tumors and lymph node (LN) metastasis in clinical stage I non-small cell lung cancer (NSCLC) patients. A total of 76 patients who underwent complete resection for clinical stage I adenocarcinoma and squamous cell carcinoma were retrospectively examined. Tumors consisted of 51 cases of adenocarcinoma and 25 cases of squamous cell carcinoma as determined by histology. LN metastasis was detected in 24.4% (19/76) of patients. Factors associated with LN metastasis on univariate analysis included LVI (p < 0.001) and increased tumor dimensions (p < 0.05). Binary logistic regression analysis showed that the presence of LVI (p < 0.001) was the only predictor of LN metastasis. LVI is significantly associated with LN metastasis in patients with clinical stage I NSCLC. These findings may be helpful in determining the most appropriate operative strategy for patients if preoperative detection of LVI becomes feasible. Georg Thieme Verlag KG Stuttgart · New York.

With the advances of technology, great progresses have been made in liquid biopsy in recent years. Liquid biopsy is currently playing a more and more important role in early diagnosis and treatment of cancer. Compared with traditional tissue biopsy, liquid biopsy is more popular in clinical practice due to its non-invasiveness, convenience and high repeatability. It has huge potential in the future. This review introduces circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA) as the most important objects in liquid biopsy, mainly focusing on their history, biological characteristics, detection technologies, limitations and applications in non-small cell lung cancer.

Pleiotrophin (PTN) is a kind of heparin binding growth factor closely related to tumor progression. This study aimed to discuss the significance of the expression of PTN in benign and malignant lung cancer tissues, especially small cell lung cancer. Lung cancer samples were collected for study and lung tissue samples with benign lesions were taken as controls. The expression of PTN was detected using tissue chip combined with the immunohistochemical method, and the differences of small cell lung cancer with non-small cell lung cancer and benign lesion tissue were compared. It was found that PTN expression was mainly located in the cytoplasm and membrane of cells; PTN expression in the lung cancer group was higher than that in the control group (p < 0.01), and PTN expression in the small cell cancer group was higher than that in the squamous carcinoma group and glandular cancer group (p < 0.05). In addition, PTN expression quantity in patients with lung cancer were in close correlation with TNM staging, pathological type and tumor differentiation degree (p < 0.05). PTN was found to express abnormally high in lung cancer, especially small cell lung cancer tissue. PTN is most likely to be a new tumor marker for diagnosis and prognosis of lung cancer.

Lung cancer is the leading cause of cancer death in North America and Western Europe. Patients with lung cancer in general have reduced physical capacity, functional capacity, poor quality of life and increased levels of anxiety and depression. Intervention studies indicate that physical training can address these issues. However, there is a lack of decisive evidence regarding the effect of physical exercise in patients with advanced lung cancer. The aim of this study is to evaluate the effects of a twelve weeks, twice weekly program consisting of: supervised, structured training in a group of advanced lung cancer patients (cardiovascular and strength training, relaxation). A randomized controlled trial will test the effects of the exercise intervention in 216 patients with advanced lung cancer (non-small cell lung cancer (NSCLC) stage IIIb-IV and small cell lung cancer (SCLC) extensive disease (ED)). Primary outcome is maximal oxygen uptake (VO₂peak). Secondary outcomes are muscle strength (1RM), functional capacity (6MWD), lung capacity (Fev1) and patient reported outcome (including anxiety, depression (HADS) and quality of life (HRQOL)). The present randomized controlled study will provide data on the effectiveness of a supervised exercise intervention in patients receiving systemic therapy for advanced lung cancer. It is hoped that the intervention can improve physical capacity and functional level, during rehabilitation of cancer patients with complex symptom burden and help them to maintain independent function for as long as possible. http://ClinicalTrials.gov, NCT01881906.

For highly selected patients with Stage III non-small-cell lung cancer (NSCLC) who relapse or have residual disease after definitive chemoradiotherapy, salvage lung resection is likely to be one of the options for local control and possible better prognosis. However, the long-term benefit has not been verified. We conducted a retrospective study on salvage surgery on a multicentre basis. Patients included in this study met the following criteria: (i) prior treatment of lung cancer with curative-intent radiotherapy (≥60 Gy); (ii) no a priori plans for induction multimodality therapy; (iii) confirmation of loco-regional recurrence or persistent tumour in the irradiated area; (iv) pretherapeutic pathological results of NSCLC and (v) Stage III disease prior to chemoradiotherapy. A total of 18 patients were eligible for evaluation (Stage IIIA/IIIB, 14/4). The prior median radiation therapy dose was 60 Gy (60-74 Gy), and the median time between the last day of radiotherapy and resection was 38 weeks. The indications for surgery were primary tumour regrowth (10 patients) or tumour persistence (8 patients). Surgical procedures included lobectomy in 13 patients and pneumonectomy in 5 patients. Postoperative complications occurred in 5 patients (28%) without perioperative death. Complete resection was shown in 16 patients (89%) and a complete pathological response in 5 patients (28%). The median follow-up time was 1405 days, and the 3-year overall survival and recurrence-free survival rates were 78 and 72%, respectively. In the highly selected Stage III NSCLC after curative-intent chemoradiation therapy, salvage surgery was safely performed and contributed to satisfactory long-term survival. © The Author 2016.

Previously, using microarray and real-time RT-PCR analysis, we established that HOXB2 is an adverse prognostic indicator for Stage I lung adenocarcinomas. HOXB2 is one of the homeobox master development-controlling genes regulating morphogenesis and cell differentiation. The molecular functions of HOXB2 were analyzed with a small interfering RNA (siRNA) approach in HOP-62 human non-small cell lung cancer (NSCLC) cells featuring high HOXB2 expression. Matrigel invasion assays and microarray gene expression analysis were compared between the HOXB2-siRNA cells and the control cells. The Matrigel invasion assays showed attenuation of HOXB2 expression by siRNA to result in a significant decrease of invasiveness compared to the control cells (p = 0.0013, paired t-test). On microarray gene expression analysis, up-regulation of many metastasis-related genes and others correlating with HOXB2 expression was observed in the control case. With attenuation of HOXB2 expression, downregulation was noted for laminins alpha 4 and 5, involved in enriched signaling, and for Mac-2BP (Mac-2 binding protein) and integrin beta 4 amongst the genes having an enriched glycoprotein ontology. HOXB2 promotes invasion of lung cancer cells through the regulation of metastasis-related genes.

Icotinib, an oral EGFR tyrosine kinase inhibitor, had shown antitumour activity and favourable toxicity in early-phase clinical trials. We aimed to investigate whether icotinib is non-inferior to gefitinib in patients with non-small-cell lung cancer. In this randomised, double-blind, phase 3 non-inferiority trial we enrolled patients with advanced non-small-cell lung cancer from 27 sites in China. Eligible patients were those aged 18-75 years who had not responded to one or more platinum-based chemotherapy regimen. Patients were randomly assigned (1:1), using minimisation methods, to receive icotinib (125 mg, three times per day) or gefitinib (250 mg, once per day) until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival, analysed in the full analysis set. We analysed EGFR status if tissue samples were available. All investigators, clinicians, and participants were masked to patient distribution. The non-inferiority margin was 1·14; non-inferiority would be established if the upper limit of the 95% CI for the hazard ratio (HR) of gefitinib versus icotinib was less than this margin. This study is registered with ClinicalTrials.gov, number NCT01040780, and the Chinese Clinical Trial Registry, number ChiCTR-TRC-09000506. 400 eligible patients were enrolled between Feb 26, 2009, and Nov 13, 2009; one patient was enrolled by mistake and removed from the study, 200 were assigned to icotinib and 199 to gefitinib. 395 patients were included in the full analysis set (icotinib, n=199; gefitinib, n=196). Icotinib was non-inferior to gefitinib in terms of progression-free survival (HR 0·84, 95% CI 0·67-1·05; median progression-free survival 4·6 months [95% CI 3·5-6·3] vs 3·4 months [2·3-3·8]; p=0·13). The most common adverse events were rash (81 [41%] of 200 patients in the icotinib group vs 98 [49%] of 199 patients in the gefitinib group) and diarrhoea (43 [22%] vs 58 [29%]). Patients given icotinib had less drug

New targeted treatments for non-small-cell lung cancer - role of nivolumab.

Non-small-cell lung cancer (NSCLC) is often diagnosed at an advanced stage of disease, where it is no longer amenable to curative treatment. During the last decades, the survival has only improved significantly for lung cancer patients who have tumors harboring a driver mutation. Therefore, there is a clear unmet need for effective therapies for patients with no mutation. Immunotherapy has emerged as an effective treatment for different cancer types. Nivolumab, a monoclonal inhibitory antibody against PD-1 receptor, can prolong survival of NSCLC patients, with a manageable toxicity profile. In two Phase III trials, nivolumab was compared to docetaxel in patients with, respectively, squamous (CheckMate 017) and non-squamous NSCLC (CheckMate 057). In both trials, nivolumab significantly reduced the risk of death compared to docetaxel (41% and 27% lower risk of death for squamous and non-squamous NSCLC, respectively). Therefore, nivolumab has been approved in the US and in Europe as second-line treatment for advanced NSCLC. Unfortunately, accurate predictive factors for patient selection are lacking, making it difficult to decide who will benefit and who will not. Currently, there are many ongoing trials that evaluate the efficacy of nivolumab in different settings and in combination with other agents. This paper reviews the present literature about the role of nivolumab in the treatment of NSCLC. Particular attention has been given to efficacy studies, toxicity profile, and current and emerging predictive factors.

Prolongation of life by adoptive cell therapy with cascade primed immune cells in four patients with non-small cell lung cancer stages IIIB and IV and a pancoast tumor: a case series

PubMed Central

2013-01-01

Introduction Despite newer treatment modalities, few patients with non-small cell lung cancer in stages IIIB and IV survive the median of one year. We present four patients with non-small cell lung cancer treated with an adjuvant therapy with cascade primed immune cells. The in vitro stimulated expression of cancer information on the patients’ monocytes matures and activates T lymphocytes to destroy cancer cells. The cascade primed immune cell therapy significantly improved the quality of life and the lifespan of all four patients; thus far, three patients survived 40, 55 and 120 months, respectively; and one patient died 39 months after diagnosis. Case presentation Patient 1, stage IV (T4N2M1): The adenocarcinoma of the 67-year-old German Caucasian man infiltrated into the mediastinal lymph nodes and iliosacral bones. Chemotherapy modalities were started immediately after diagnosis of cancer, and cascade primed immune cell therapy one year later. The patient survived 39 months. Patient 2, stage IV (T3N3M1a): The 62-year-old German Caucasian woman presented with adenocarcinoma of the lower lobe with infiltrated lymph nodes of the mediastinum and malignant pleural effusion. Chemotherapy, radiation and the cascade primed immune cell therapy were administered together. The patient is still alive after 40 months. Patient 3, stage IIIB (T4N1-2M0): The 75-year-old German Caucasian woman presented with an undifferentiated tumor and a separate tumor nodule in the ipsilateral lobe. The patient received only cascade primed immune cell therapy after tumor resection and has survived for the last 55 months. Patient 4, pancoast tumor (IIIB, T3N3M0): The 77-year-old German Caucasian man presented with an undifferentiated tumor that infiltrated the lymph nodes, the clavicle, one rib and the plexus brachialis. In addition to chemotherapy and radiation, cascade primed immune cells were administered every weekday for one year. After four months, no living tumor cell was detected in

Nivolumab, an immune checkpoint inhibitor, is now a standard treatment for previously treated advanced non-small-cell lung cancer based on the results from phase III clinical trials. We evaluated the real-world efficacy and safety of nivolumab in a nonselected population and identified the clinical characteristics that influence efficacy. A total of 142 patients with advanced non-small-cell lung cancer who were administered nivolumab at Keio University and affiliated hospitals in Japan from January to July 2016 were enrolled. The treatment efficacy and adverse events were retrospectively reviewed, and the clinical characteristics associated with the nivolumab response were evaluated using univariate and stratified analyses and the Cochran-Mantel-Haenszel test. The objective response rate was 17.0% (95% confidence interval [CI], 12.0%-24.0%), the median progression-free survival (PFS) was 58 days (95% CI, 50-67 days), and the proportion of patients with adverse events of any grade was 45.0%. EGFR/ALK mutation status was inversely associated with the treatment response (P < .05), and the difference in PFS for the mutation-positive versus mutation-negative patients was statistically significant (49 vs. 63 days; hazard ratio, 1.9; 95% CI, 1.1-5.2; P = .029). Previous radiotherapy also had a positive association with the treatment response (P = .012). The objective response rate, PFS, and adverse event profiles were comparable to those observed in previous clinical trials. EGFR/ALK mutation-negative status and previous radiotherapy might be key clinical characteristics associated with a positive treatment response. Our findings could aid in the efficient immunotherapeutic management of lung cancer. Copyright © 2018 Elsevier Inc. All rights reserved.

The NCIC Clinical Trials Group conducted the BR.21 trial, a randomized placebo-controlled trial of erlotinib (an epidermal growth factor receptor tyrosine kinase inhibitor) in patients with previously treated advanced non-small cell lung cancer. This trial accrued patients between August 14, 2001, and January 31, 2003, and found that overall survival and quality of life were improved in the erlotinib arm than in the placebo arm. However, funding restrictions limit access to erlotinib in many countries. We undertook an economic analysis of erlotinib treatment in this trial and explored different molecular and clinical predictors of outcome to determine the cost-effectiveness of treating various populations with erlotinib. Resource utilization was determined from individual patient data in the BR.21 trial database. The trial recruited 731 patients (488 in the erlotinib arm and 243 in the placebo arm). Costs arising from erlotinib treatment, diagnostic tests, outpatient visits, acute hospitalization, adverse events, lung cancer-related concomitant medications, transfusions, and radiation therapy were captured. The incremental cost-effectiveness ratio was calculated as the ratio of incremental cost (in 2007 Canadian dollars) to incremental effectiveness (life-years gained). In exploratory analyses, we evaluated the benefits of treatment in selected subgroups to determine the impact on the incremental cost-effectiveness ratio. The incremental cost-effectiveness ratio for erlotinib treatment in the BR.21 trial population was $94,638 per life-year gained (95% confidence interval = $52,359 to $429,148). The major drivers of cost-effectiveness included the magnitude of survival benefit and erlotinib cost. Subgroup analyses revealed that erlotinib may be more cost-effective in never-smokers or patients with high EGFR gene copy number. With an incremental cost-effectiveness ratio of $94 638 per life-year gained, erlotinib treatment for patients with previously treated

Supportive care in the era of immunotherapies for advanced non-small-cell lung cancer.

The therapeutic armamentarium for advanced non-small-cell lung cancer has evolved considerably over the past years. Immune checkpoint inhibitors targeting programmed cell death-1 such as pembrolizumab and nivolumab or programmed cell death ligand 1 such as atezolizumab, durvalumab and avelumab have shown favorable efficacy results in this patient population in the first-line and second-line setting. These immunotherapies are associated with a distinct toxicity profile based on autoimmune organ toxicity which is a new challenge for supportive care during treatment with these drugs. The differential diagnosis of events occurring during immune checkpoint inhibitor treatment is broad: they can be due to immune-related or nonimmune-related adverse events, atypical tumor responses (pseudoprogression or hyperprogression) or events related to comorbidities or other treatments. The management of these patients includes a thorough baseline clinical, biological and radiologic evaluation, patient education, correct follow-up and management by a multidisciplinary team with a central role for the medical oncologist. Immune-related toxicities should be managed according to available guidelines.

For non-small cell lung cancer (NSCLC) patients at stage IB, adjuvant chemotherapy does not improve survival. Evidence suggests that dendritic cell (DC)-activated cytokine-induced killer (DC-CIK) cell therapy in addition to chemotherapy improves survival for stage I-IIIA NSCLC patients after surgery, but there are not enough data to confirm this benefit specifically for those at stage IB. Herein, we retrospectively evaluated the efficacy and safety of this therapy administered to stage IB NSCLC patients. Sixty-six patients were treated with four-cycle adjuvant chemotherapy initiated 3 weeks after surgical resection. In addition, 28 of these patients underwent DC-CIK therapy on a trimonthly basis (average 3.1 times, range 1-6) beginning 1 month after chemotherapy. The disease-free survival (DFS) rates of the two groups were statistically similar, although patients who received DC-CIK therapy showed slightly higher 1- and 2-year DFS rates (100.0% and 96.4%, respectively, compared with 81.6% and 76.3%). More importantly, patients in the DC-CIK therapy group had significantly longer overall survival (p=0.018). For patients who received treatment after recurrence, the DC-CIK therapy group had longer progression-free survival compared with the chemotherapy-only group. In addition, patients given DC-CIK therapy experienced less fatigue and appetite loss. The rate of adverse side effects was similar between the two groups. In conclusion, for these stage IB NSCLC patients, DC-CIK therapy significantly improved 2-year DFS rates compared with those who received chemotherapy only. DC-CIK therapy also benefited patients' quality of life, and adverse events were acceptable.

Highlights: • TIPE2 is down-regulated in NSCLC tissues. • TIPE2 inhibits NSCLC cell proliferation, colony formation and invasion. • TIPE2 reduces the anti-apoptotic Bcl-XL protein and mesenchymal marker N-cadherin expression. - Abstract: The present study aims to investigate the expression pattern of TIPE2 protein and its clinical significance in human non-small cell lung cancer (NSCLC). We investigated the expression levels of TIPE2 in 96 NSCLC tumor samples by immunohistochemistry and then analyzed its clinical significance. Furthermore, the role of TIPE2 on the biological properties of the NSCLC cell line H1299 and A549 was experimentally tested in vitro and in vivo.more » We found that the expression level of TIPE2 was significantly higher in normal lung tissues compared with NSCLC tissues (P < 0.001), and TIPE2 downregulation was significantly correlated with advanced TNM stage (P = 0.006). TIPE2 expression was lower in lung cancer cell lines than normal bronchial cell line HBE. Transfection of TIPE2 plasmid was performed in H1299 and A549 cells. TIPE2 overexpression inhibited lung cancer cell proliferation, colony formation and cell invasive in vitro, and prevented lung tumor growth in vivo. In addition, TIPE2 transfection reduced the anti-apoptotic Bcl-XL protein and mesenchymal marker N-cadherin expression. Taken together, our results demonstrate that TIPE2 might serve as a tumor suppressor in NSCLC progression.« less

Lung cancer is the leading cause of cancer deaths worldwide. Standard chemotherapy has been shown to improve quality of life and has a modest influence on overall survival. This modest improvement in survival is partly due to the choice of chemotherapy regimens that have been based on prognostic factors such as age, performance status and comorbidities of the patient. This underlines the importance of developing a more personalized therapy for patients with non-small cell lung cancer. Such an approach may reduce the variation in how individual patients respond to medications by tailoring therapies to their genetic profile. In this review we focus on several aspects of customized therapy, looking not only at patient characteristics but also to tumor histology and specific tumor biomarkers. PMID:21904581

2015-03-01

Our increased understanding of the molecular subsets of non-small cell lung cancer (NSCLC) has led to the development of highly effective targeted therapies. In particular, the outcomes of patients with advanced NSCLC driven by the EML4-ALK fusion protein, which comprise 3-5% of cases, have remarkably improved with the use of crizotinib, an oral multi-tyrosine kinase inhibitor that targets ALK. However, patients inevitably develop progression while on crizotinib due to various mechanisms of resistance. Alectinib is a novel oral small molecule that inhibits ALK with high potency and selectivity, and demonstrates promising antitumor effects in NSCLC. Preclinical studies have shown that it is also active against several mutant forms of ALK that confer resistance to crizotinib, including the gatekeeper mutation L1196M. Moreover, an objective response rate of over 90% was observed in a phase I trial. Due to the impressive results of early phase studies, alectinib was approved for the treatment of advanced ALK-positive NSCLC in Japan, while it has been granted a breakthrough therapy designation by the FDA. A phase III trial is currently ongoing. This review will describe the biology and significance of ALK rearrangements in NSCLC, ALK inhibition by crizotinib and mechanisms of resistance, as well as the preclinical and clinical evidence for the novel ALK inhibitor alectinib.

Non-small cell lung cancer is the most common type of lung cancer. Both environmental and genetic risk factors contribute to lung carcinogenesis. We conducted a genome-wide interaction analysis between single nucleotide polymorphisms (SNPs) and smoking status (never- versus ever-smokers) in a European-descent population. We adopted a two-step analysis strategy in the discovery stage: we first conducted a case-only interaction analysis to assess the relationship between SNPs and smoking behavior using 13336 non-small cell lung cancer cases. Candidate SNPs with P-value <0.001 were further analyzed using a standard case-control interaction analysis including 13970 controls. The significant SNPs with P-value <3.5 × 10-5 (correcting for multiple tests) from the case-control analysis in the discovery stage were further validated using an independent replication dataset comprising 5377 controls and 3054 non-small cell lung cancer cases. We further stratified the analysis by histological subtypes. Two novel SNPs, rs6441286 and rs17723637, were identified for overall lung cancer risk. The interaction odds ratio and meta-analysis P-value for these two SNPs were 1.24 with 6.96 × 10-7 and 1.37 with 3.49 × 10-7, respectively. In addition, interaction of smoking with rs4751674 was identified in squamous cell lung carcinoma with an odds ratio of 0.58 and P-value of 8.12 × 10-7. This study is by far the largest genome-wide SNP-smoking interaction analysis reported for lung cancer. The three identified novel SNPs provide potential candidate biomarkers for lung cancer risk screening and intervention. The results from our study reinforce that gene-smoking interactions play important roles in the etiology of lung cancer and account for part of the missing heritability of this disease.

Surgery is still the main treatment in early-stage of non-small cell lung cancer with 5-year survival of stage IA patients exceeding 80%, but 5-year survival of stage II patients rapidly decreasing with tumor size, N status, and visceral pleura invasion. The major metastatic risk in such patients has supported clinical research assessing systemic or loco-regional perioperative treatments. Modern phase 3 trials clearly validated adjuvant or neo-adjuvant platinum-based chemotherapy in resected stage I-III patients as a standard treatment of which value has been reassessed several independent meta-analyses, showing a 5% benefit in 5y-survival, and a decrease of the relative risk for death around from 12 to 25%. Conversely perioperative treatments were not validated for stage IA and IB patients. In more advanced stage patients, neo-adjuvant radio-chemotherapy has not been validated either. Adjuvant radiotherapy for N2 patients is currently tested in the large international phase 3 trial Lung-ART/IFCT-0503. The development of video-assisted thoracic surgery (VATS) has helped adjuvant chemotherapies for elderly patients. Perioperative targeted treatments in NSCLC with EGFR or ALK molecular alterations is currently assessed in the U.S. ALCHEMIST prospective trial. Finally, the role of immune check-points inhibitors is currently evaluated in a large international phase 3 trial testing adjuvant anti-PD-L1 monoclonal antibody, the BR31/IFCT-1401 trial, while a proof-of principle neo-adjuvant trial IONESCO/IFCT-1601, has just begun by the end of the 2016 year, with survival results of both trials expected in 5 to 7 years.

Erlotinib as a single agent in select subsets of patients with advanced non-small-cell lung cancer.

PubMed

Carrión, Ramón Pérez; Gracián, Antonio Cubillo; Hernandez, Pedro Salinas

Erlotinib is an orally active inhibitor of the epidermal growth factor receptor that is effective for the treatment of non-small-cell lung cancer (NSCLC). Patients with a poor performance status (PS) of 2 constitute up to 40% of advanced NSCLC. This group of patients have a lower life expectancy and are thought to have a greater degree of treatment-related toxicity. The clinical benefit on 238 patients with poor PS included in an open-label, nonrandomized, phase II trial of erlotinib in advanced/metastatic NSCLC was 57.58% defined as complete response plus partial response plus stable disease. Median time to progression was 2.9 months. This review will summarize available data about erlotinib on patients with a PS of 2.

Genomic profiling of cell-free circulating tumor DNA (ctDNA) is a potential alternative to repeat invasive biopsy in patients with advanced cancer. We report the first real-world cohort of comprehensive genomic assessments of patients with non-small-cell lung cancer (NSCLC) in a Chinese population. We performed a retrospective analysis of patients with advanced or metastatic NSCLC whose physician requested ctDNA-based genomic profiling using the Guardant360 platform from January 2016 to June 2017. Guardant360 includes all 4 major types of genomic alterations (point mutations, insertion-deletion alterations, fusions, and amplifications) in 73 genes. Genomic profiling was performed in 76 patients from Hong Kong during the 18-month study period (median age, 59.5 years; 41 men and 35 women). The histologic types included adenocarcinoma (n = 10), NSCLC, not otherwise specified (n = 58), and squamous cell carcinoma (n = 8). In the adenocarcinoma and NSCLC, not otherwise specified, combined group, 62 of the 68 patients (91%) had variants identified (range, 1-12; median, 3), of whom, 26 (42%) had ≥ 1 of the 7 National Comprehensive Cancer Network-recommended lung adenocarcinoma genomic targets. Concurrent detection of driver and resistance mutations were identified in 6 of 13 patients with EGFR driver mutations and in 3 of 5 patients with EML4-ALK fusions. All 8 patients with squamous cell carcinoma had multiple variants identified (range, 1-20; median, 6), including FGFR1 amplification and ERBB2 (HER2) amplification. PIK3CA amplification occurred in combination with either FGFR1 or ERBB2 (HER2) amplification or alone. Genomic profiling using ctDNA analysis detected alterations in most patients with advanced-stage NSCLC, with targetable aberrations and resistance mechanisms identified. This approach has demonstrated its feasibility in Asia. Copyright © 2018 Elsevier Inc. All rights reserved.

Singapore Cancer Network (SCAN) Guidelines for Adjuvant Chemotherapy in Resected Non-Small Cell Lung Cancer.

PubMed

2015-10-01

The SCAN lung cancer workgroup aimed to develop Singapore Cancer Network (SCAN) clinical practice guidelines for the use of adjuvant systemic therapy for non-small cell lung cancer in Singapore. The workgroup utilised a modified ADAPTE process to calibrate high quality international evidence-based clinical practice guidelines to our local setting. Five international guidelines were evaluated- those developed by the National Comprehensive Cancer Network (2014), European Society of Medical Oncology (2014), National Institute of Clinical Excellence (2012), Scottish Intercollegiate Guidelines Network (2014), and the Cancer Care Council Australia (2012). Recommendations on the selection of patients, chemotherapy regimen, treatment for stage I disease, treatment for positive margins and treatment options for pN2 disease with negative margins were produced. These adapted guidelines form the SCAN Guidelines 2015 for adjuvant systemic therapy of non-small cell lung cancer.

The loss of muscle is common in patients with advanced non-small-cell lung cancer (NSCLC) and contributes to the high morbidity and mortality of this group. The exact mechanisms behind the muscle loss are unclear. To investigate this, 4 patients with stage IV NSCLC who met the clinical definitions for sarcopenia and cachexia were recruited, along with 4 age-matched healthy volunteers. After an overnight fast, biopsy specimens were obtained from the vastus lateralis, and the key components associated with inflammation and the control of muscle protein, carbohydrate, and fat metabolism were assessed. Compared with the healthy volunteers, significant increases in mRNA levels for interleukin-6 and NF-κB signaling and lower intramyocellular lipid content in slow-twitch fibers were observed in NSCLC patients. Although a significant decrease in phosphorylation of the mechanistic target of rapamycin (mTOR) signaling protein 4E-BP1 (Ser 65 ) was observed, along with a trend toward reduced p70 S6K (Thr 389 ) phosphorylation (P = .06), no difference was found between groups for the mRNA levels of MAFbx (muscle atrophy F box) and MuRF1 (muscle ring finger protein 1), chymotrypsin-like activity of the proteasome, or protein levels of multiple proteasome subunits. Moreover, despite decreases in intramyocellular lipid content, no robust changes in mRNA levels for key proteins involved in insulin signaling, glycolysis, oxidative metabolism, or fat metabolism were observed. These findings suggest that examining the contribution of suppressed mTOR signaling in the loss of muscle mass in late-stage NSCLC patients is warranted and reinforces our need to understand the potential contribution of impaired fat metabolism and muscle protein synthesis in the etiology of cancer cachexia.

CD147, a widely expressed cell surface glycoprotein in cancer, is associated with tumor invasiveness and chemotherapy resistance. Recently, CD147 is also regarded as a potential therapeutic target for cancer therapy. The aim of the study was to investigate CD147 expression in non-small cell lung cancer (NSCLC), and evaluate its correlation with cisplatin-based chemotherapy resistance. In this study, we examined immunohistochemically the expression of CD147 in 118 advanced NSCLC cases treated with cisplatin-based chemotherapy, and then the association of CD147 expression with clinicopathological characteristics was analyzed. Furthermore, RNA interference approach was used to silence CD147 expression in a cisplatin-resistant human lung cancer cell line A549/DDP, and the inhibition effect of cisplatin on tumor cells was assayed by MTT. In the overall series, positive CD147 expression was observed in 101/118 (85.6%) cases. A membranous CD147 pattern was identified in 76/101 (75.2%) of CD147 positive tumors. CD147 membranous expression,but not the overall CD147 expression, was associated with poor response to cisplatin-based chemotherapies and a poor prognosis in advanced NSCLC patients. In vitro results showed that silencing CD147 increased the proliferation inhibitory effect of cisplatin to A549/DDP cells. In conclusion, our study indicated that membranous CD147 expression is a predictive factor of the response to cisplatin-based chemotherapies, and the use of CD147-targeted therapeutic adjuvants might be considered in the treatment of advanced NSCLC patients.

Doublecortin and CaM kinase-like-1 (DCLK1) regulates microtubule polymerization in migrating neurons. Recently, DCLK1 has been reported to act as an intestinal tumor stem cell marker and has been shown to be expressed in cancer cells and in the stroma of breast, colon, pancreatic, and prostate cancers. Here, we studied DCLK1 expression in non-small cell lung cancer (NSCLC) by immunohistochemistry in association with clinicopathological factors and patient prognosis. DCLK1 expression was analyzed by immunohistochemical staining of surgical specimens from 232 patients with pathological stage I NSCLC, including 187 adenocarcinomas. Relationships between the expression status of DCLK1 and clinicopathological factors were examined. The impact of DCLK1 expression status and other clinicopathological factors on survival was evaluated by univariate and multivariate analyses. Thirty-three (14.2%) of 232 patients had DCLK1-positive cancer cells. DCLK1 was also expressed in the tumor stroma in most of the specimens and was significantly associated with DCLK1 expression in cancer cells. DCLK1-positive cancer cells were more common in non-adenocarcinoma tissues (44.4%) than in adenocarcinoma tissues (7.0%). Moreover, positive DCLK1 expression in cancer cells and stromal cells was correlated with a worse prognosis. Histological analyses revealed that the presence of DCLK1-positive cancer cells was an independent risk factor for poor prognosis in adenocarcinoma, but was not significantly associated with prognosis in non-adenocarcinoma. DCLK1 expression was observed in tumor cells in patients with pathological stage I NSCLC and was correlated with adverse prognosis, especially in patients with adenocarcinoma. DCLK1 may be a potential new therapeutic target.

There have been remarkable advances in the targeted treatment of advanced non-small cell lung cancer (NSCLC) over the past several years. Survival outcomes are steadily improving as management paradigms shift in the diagnosis and treatment of advanced NSCLC. Customizing treatment based on histology and molecular typing has become a standard of care in this era of targeted therapy. While new chemotherapeutic agents have proven effective, the pivotal role of platinum-based chemotherapy doublets has been confirmed. Maintenance chemotherapy has become an option, but who to employ it in remains unclear in the real-world setting. Efforts to overcome resistance to targeted agents are ongoing utilizing combination regimens of chemotherapy plus targeted agents, but optimizing combination strategies needs further exploration. This review highlights recent developments in novel chemotherapeutics and in chemotherapy strategies over the past two years. Despite advances in molecular medicine, there remains an essential role for chemotherapy in advanced NSCLC, even in the recent targeted therapy era.

The majority of normal-tissue complication probability (NTCP) models for acute esophageal toxicity (AET) in advanced stage non-small cell lung cancer (AS-NSCLC) patients treated with (chemo-)radiotherapy are based on three-dimensional conformal radiotherapy (3D-CRT). Due to distinct dosimetric characteristics of intensity-modulated radiation therapy (IMRT), 3D-CRT based models need revision. We established a multivariable NTCP model for AET in 149 AS-NSCLC patients undergoing IMRT. An established model selection procedure was used to develop an NTCP model for Grade ⩾2 AET (53 patients) including clinical and esophageal dose-volume histogram parameters. The NTCP model predicted an increased risk of Grade ⩾2 AET in case of: concurrent chemoradiotherapy (CCR) [adjusted odds ratio (OR) 14.08, 95% confidence interval (CI) 4.70-42.19; p<0.001], increasing mean esophageal dose [Dmean; OR 1.12 per Gy increase, 95% CI 1.06-1.19; p<0.001], female patients (OR 3.33, 95% CI 1.36-8.17; p=0.008), and ⩾cT3 (OR 2.7, 95% CI 1.12-6.50; p=0.026). The AUC was 0.82 and the model showed good calibration. A multivariable NTCP model including CCR, Dmean, clinical tumor stage and gender predicts Grade ⩾2 AET after IMRT for AS-NSCLC. Prior to clinical introduction, the model needs validation in an independent patient cohort. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The optimal chemotherapy regimen for non-small cell lung cancer patients with interstitial lung disease is unclear. We therefore investigated the safety and efficacy of carboplatin plus nab-paclitaxel as a first-line regimen for non-small cell lung cancer in patients with interstitial lung disease. We retrospectively reviewed advanced non-small cell lung cancer patients with interstitial lung disease who received carboplatin plus nab-paclitaxel as a first-line chemotherapy regimen at Hyogo Cancer Center between February 2013 and August 2016. interstitial lung disease was diagnosed according to the findings of pretreatment chest high-resolution computed tomography. Twelve patients were included (male, n = 11; female, n = 1). The overall response rate was 67% and the disease control rate was 100%. The median progression free survival was 5.1 months (95% CI: 2.9-8.3 months) and the median overall survival was 14.9 months (95% CI: 4.8-not reached). A chemotherapy-related acute exacerbation of interstitial lung disease was observed in one patient; the extent of this event was Grade 2. There were no treatment-related deaths. Carboplatin plus nab-paclitaxel, as a first-line chemotherapy regimen for non-small cell lung cancer, showed favorable efficacy and safety in patients with preexisting interstitial lung disease. © The Author 2017.

Immune checkpoint inhibitors in small cell lung cancer.

PubMed

Pakkala, Suchita; Owonikoko, Taofeek K

2018-02-01

Small cell lung cancer (SCLC) is a rapidly progressive cancer that often debilitates patients within months of detection and quickly becomes refractory to the limited options of therapy. While SCLC is not generally considered an immunogenic tumor, clinical experience suggests that patients with robust immune response manifesting as paraneoplastic syndrome are more likely to present with limited stage of the disease and tend to have a better prognosis. Monoclonal antibodies targeting critical negative regulators of immune response, so called immune checkpoints, such as cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed death 1 (PD-1) have expanded the application of immune-based therapies to increasing number of advanced stage cancers. These agents overcome the inhibitory immune signals leading to a heightened immune response against cancer cells. These immune checkpoint inhibitors have established efficacy leading to regulatory approval for their use in many cancer types including non-small cell lung cancer (NSCLC). Evaluation of the CTLA-4 inhibitor, ipilimumab and PD-1 inhibitors, nivolumab and pembrolizumab in SCLC have shown encouraging signal but definitive studies are still ongoing. In this review, we discuss the rationale behind the use of checkpoint inhibitors in SCLC, contextualize the results of early trials of immunotherapy agents in SCLC and project the future evolution of this strategy.

Chemotherapy is associated with a risk of vascular damage. Novel anti-angiogenic agents, which can directly affect tumor angiogenesis, are increasingly being used. However, the effects of these agents on normal vasculature are not well understood. Here, we evaluated the effects of chemotherapy in general, and the anti-angiogenic agent bevacizumab, more specifically, on the pulmonary vasculature in patients with advanced non-squamous non-small-cell lung cancer (NSCLC). For this, we used the cross-sectional area of pulmonary vessels (CSA), which is an easily measurable indicator of small pulmonary vasculature on non-contrast chest computed tomography (CT). We retrospectively reviewed CT scans of the lungs of 75 chemo-naïve patients with advanced non-squamous NSCLC, for measurement of CSA, before and after first-line platinum-based chemotherapy, using a semi-automatic image-processing program. Measured vessels were classified in two groups: small vessels with CSA <5 mm(2) and large vessels with CSA between 5 and 10 mm(2). The CSAs for each group of vessels were calculated and summed separately, and expressed as a percentage of the total lung area (%CSA<5 and %CSA5-10). Chemotherapy was associated with a selective decrease in small-diameter vessels, with a significant decrease in %CSA<5, but not %CSA5-10. When comparing chemotherapy with bevacizumab (n = 38) and without bevacizumab (n = 37), there was no significant difference in the reduction of %CSA<5. Platinum-based chemotherapy might induce small pulmonary vascular damage. Use of bevacizumab does not enhance the reduction in area of pulmonary vessels.

Local-regional control (LRC) rates for non-small cell lung cancer after chemoradiotherapy were studied (using two different definitions of LRC) for the association between LRC and survival. Seven legacy Radiation Therapy Ooncology Group trials of chemoradiotherapy for locally advanced non-small cell lung cancer were analyzed. Two different definitions of LRC were studied: (1) freedom from local progression (FFLP-LRC), the traditional Radiation Therapy Oncology Group methodology, in which a failure is intrathoracic tumor progression by World Health Oorganization criteria; and (2) response-mandatory (strict-LRC), in which any patient not achieving at least partial response was considered to have failure at day 0. Testing for associations between LRC and survival was performed using a Cox multivariate model that included other potential predictive factors. A total of 1390 patients were analyzed. The LRC rate at 3 years was 38% based on the FFLP-LRC definition and 14% based on the strict-LRC definition. Performance status, concurrent chemotherapy, and radiotherapy dose intensity (biologically equivalent dose) were associated with better LRC (using either definition). With the strict-LRC definition (but not FFLP-LRC), age was also important. There was a powerful association between LRC and overall survival (p, 0.0001) on univariate and multivariate analyses. Age, performance status, chemotherapy sequencing, and biologically equivalent dose were also significantly associated with survival. Histology and gender were also significant if the strict-LRC model was used. LRC is associated with survival. The definition of LRC affects the results of these analyses. A consensus definition of LRC, incorporating functional imaging and/or central review, is needed, with the possibility of using LRC as a surrogate end point in future trials.

For patients with stage III non-small cell lung cancer treated with induction chemotherapy (ICT), delayed initiation of subsequent radiotherapy (RT) may allow for repopulation in the interval between treatment modalities and during the early phase of RT. We quantified the impact of postinduction RT timing by evaluating the pace of tumor regrowth. Institutionally approved retrospective review identified 21 analyzable patients with stage III non-small cell lung cancer who had platinum-based ICT followed by RT+/- chemotherapy from 2002 to 2009. Radiographic response was determined by RECIST criteria and the volume of the single largest tumor mass on the pre-ICT, post-ICT, and RT-planning computed tomography scans. After ICT, the median percent volume change from pre-ICT baseline was -41% (range -86 to +86%). By the RT-planning computed tomography scan, the median percent volume change from the post-ICT timepoint was +40% (range -11 to +311%) and the median volume change was +20 ml (range -4 to 102 ml); these changes were significant (p = 0.0002). Similar results were seen for tumor diameter. A correlation was observed between the amount of delay and degree of regrowth for percent volume (p = 0.0006) and percent diameter change (p = 0.003). A delay greater than 21 days produced greater increases in percent volume change (p = 0.002) and percent diameter (p = 0.055) than lesser delays. After ICT, tumor regrowth can occur within a few weeks. Radiation treatment planning should begin as soon as possible after the administration of ICT to maximize the benefits of cytoreduction.

We evaluated the long-term outcomes of clinical stage IA non-small cell lung cancer (NSCLC) patients with combined pulmonary fibrosis and emphysema (CPFE) who underwent lobectomy. We reviewed the chest computed tomography (CT) findings and divided the patients into normal, fibrosis, emphysema and CPFE groups. We evaluated the relationships among the CT findings, the clinicopathological findings and postoperative survival. The patients were classified into the following groups based on the preoperative chest CT findings: normal lung, n = 187; emphysema, n = 62; fibrosis, n = 8; and CPFE, n = 17. The patients with CPFE were significantly older, more likely to be men and smokers, had a higher KL-6 level and lower FEV 1.0% value and had a higher rate of squamous cell carcinoma. The 5-year overall survival (OS) and disease-free survival rates were as follows: normal group, 82.5 and 76.8%; emphysema group, 80.0 and 74.9%; fibrosis group, 46.9 and 50%; and CPFE group, 36.9 and 27.9%, respectively (p < 0.01). A univariate and multivariate analysis determined that the pathological stage and CT findings were associated with OS. CPFE is a significantly unfavorable prognostic factor after lobectomy, even in early-stage NSCLC patients with a preserved lung function.

This study aims to compare the radiobiological response of two stereotactic body radiotherapy (SBRT) schedules for patients with stage I peripheral non-small cell lung cancer (NSCLC) using radiobiological modeling methods. Volumetric modulated arc therapy (VMAT)-based SBRT plans were designed using two dose schedules of 1 × 34 Gy (34 Gy in 1 fraction) and 4 × 12 Gy (48 Gy in 4 fractions) for 19 patients diagnosed with primary stage I NSCLC. Dose to the gross target volume (GTV), planning target volume (PTV), lung and chest wall (CW) were converted to biologically equivalent dose in 2 Gy fraction (EQD2) for comparison. Five different radiobiological models were employed to predict the tumor control probability (TCP) value. Three additional models were utilized to estimate the normal tissue complication probability (NTCP) value for the lung and the modified equivalent uniform dose (mEUD) value to the CW. Our result indicates that the 1 × 34 Gy dose schedule provided a higher EQD2 dose to the tumor, lung and CW. Radiobiological modeling revealed that the TCP value for the tumor, NTCP value for the lung and mEUD value for the CW were 7.4% (in absolute value), 7.2% (in absolute value) and 71.8% (in relative value) higher on average, respectively, using the 1 × 34 Gy dose schedule.

Long non-coding RNAs (lncRNAs) have been found to be dysregulated in a variety of tumors. The lncRNA-Low Expression in Tumor (LET) is a recently identified lncRNA, but its expression pattern and biological significance in human non-small cell lung cancer (NSCLC) are still largely unknown. In this study, we found that lncRNA-LET was significantly downregulated in human NSCLC lung tissues and cell lines. Decreased lncRNA-LET expression was strongly associated with advanced tumor stages and poorer overall survival of NSCLC patients. Functionally, overexpression of lncRNA-LET in NSCLC H292 cells significantly suppressed cell proliferation, migration and invasion, and promoted cell cycle arrest and apoptosis, while knockdown of lncRNA-LET in NSCLC H1975 cells showed an opposite effect, pointing to a tumor-suppressive role for lncRNA-LET in NSCLC. Mechanistically, we demonstrated that lncRNA-LET overexpression significantly reduced the expression of Notch1 intracellular Domain (NICD1) in H292 cells while knockdown of lncRNA-LET increased NICD1 expression in H1975 cells. Similarly, NSCLC lung tissues with high levels of lncRNA-LET had lower NICD1 expression. Thus, our results provide a strong rationale for lncRNA-LET to be used as a prognostic indicator and a potent therapeutic target for NSCLC patients, and highlight a novel lncRNA-LET/Notch axis in regulating NSCLC cell fate and tumor progression.

This study was aimed at understanding the functional significance of HOXA11 hypermethylation in non-small cell lung cancer (NSCLC). HOXA11 hypermethylation was characterized in six lung cancer cell lines, and its clinical significance was analyzed using formalin-fixed paraffin-embedded tissues from 317 NSCLC patients, and Ki-67 expression was analyzed using immunohistochemistry. The promoter region of HOXA11 was highly methylated in six lung cancer cell lines, but not in normal bronchial epithelial cells. The loss of expression was restored by treatment of the cells with a demethylating agent, 5-aza-2'-deoxycytidine (5-Aza-dC). Transient transfection of HOXA11 into H23 lung cancer cells resulted in the inhibition of cell migration and proliferation. HOXA11 hypermethylation was found in 218 (69%) of 317 primary NSCLCs. HOXA11 hypermethylation was found at a higher prevalence in squamous cell carcinoma than in adenocarcinoma (74% vs. 63%, respectively). HOXA11 hypermethylation was associated with Ki-67 proliferation index (P = 0.03) and pT stage (P = 0.002), but not with patient survival. Patients with pT2 and pT3 stages were 1.85 times (95% confidence interval [CI] = 1.04-3.29; P = 0.04) and 5.47 times (95% CI = 1.18-25.50; P = 0.01), respectively, more likely to show HOXA11 hypermethylation than those with pT1 stage, after adjusting for age, sex, and histology. In conclusion, the present study suggests that HOXA11 hypermethylation may contribute to the progression of NSCLC by promoting cell proliferation or migration. PMID:24259349

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 radiationmore » 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.

A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was 'Is stereotactic ablative radiotherapy equivalent to sublobar resection in high-risk surgical patients with Stage I non-small cell lung cancer?'. Altogether over 318 papers were found, of which 18 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Stereotactic ablative radiotherapy (SABR) and sublobar resection (SLR) offer clear survival benefit in the treatment of early-stage non-small-cell lung cancer (NSCLC) in high-risk patients unsuitable for lobectomy and SABR has shown good results in medically operable patients. No randomized data are available comparing SLR and SABR, and therefore, data from prospective studies were compared. Overall survival at 1 year was similar between patients treated with SABR and SLR (81-85.7 vs 92%); however, overall 3-year survival was higher following SLR (87.1 vs 45.1-57.1%). There was no statistically significant difference in local recurrence in patients treated with SABR compared with SLR (3.5-14.5 vs 4.8-20%). Both treatment modalities are associated with complications. Fatigue (31-32.6%), pneumonitis (2.1-12.5%) and chest wall pain (3.1-12%) were common following SABR; however, serious grade 3 and 4 toxicity were rare. Morbidity following SLR was reported between 7.3 and 33.7%. Thirty-day mortality following SABR was 0%, while predicted 30-day mortality following a lung resection, using the thoracoscore predictive model ranges between 1 and 2.6%. Treatment for early-stage NSCLC should be tailored to individual patients. SABR is an acceptable alternative to SLR in high-risk patients but comparative data are required.

The Ki-67 antigen (Ki-67) is the most reliable immunohistochemical marker for evaluation of cell proliferation in non-small cell lung cancer. However, the mechanisms underlying the regulation of protein levels of Ki-67 in non-small cell lung cancer have remained elusive. In this study, we found that Ki-67 and ubiquitin-specific processing protease 7 (USP7) protein were highly expressed in the nucleus of non-small cell lung cancer cells. Furthermore, statistical analysis uncovered the existence of a strong correlation between Ki-67 and USP7 levels. We could also show that the protein levels of Ki-67 in non-small cell lung cancer cells significantly decreased after treatment with P22077, a selective chemical inhibitor of USP7, while the Ki-67 mRNA levels were unperturbed. Similar results were obtained by knocking down USP7 using short hairpin RNA (shRNA) in lung cancer cells. Interestingly, we noticed that ubiquitination levels of Ki-67 increased dramatically in USP7-silenced cells. The tests in vitro and vivo showed a significant delay in tumor cell growth upon knockdown of USP7. Additionally, drug sensitivity tests indicated that USP7-silenced A549 cells had enhanced sensitivity to paclitaxel and docetaxel, while there was no significant change in sensitivity toward carboplatin and cisplatin. Taken together, these data strongly suggest that the overexpression of USP7 might promote cell proliferation by deubiquitinating Ki-67 protein, thereby maintaining its high levels in the non-small cell lung cancer. Our study also hints potential for the development of deubiquitinase-based therapies, especially those targeting USP7 to improve the condition of patients diagnosed with non-small cell lung cancer.

Non-small cell lung cancer is one of the most commom malignant tumor being harmful to people's life and health. Most of the patients have developed to the last stage which not suitable for surgical indications, so radiation and chemotherapy is the main treatment strategy. In recent years, with the theory of anti-angiogenesis therapy for malignant tumors, apatinib as a promising novel medicine to treat malignant tumors, represents synergistic antitumor effects in combination with radiotherapy. The underlying mechanisms may include make blood vessel normalization, alleviating inner hypoxia, and angiogenic factors regulation. Apatinib in combination with radiotherapy may become a new and effective treatment strategy of non-small cell lung cancer.

Lung cancer continues to be one of the leading causes of death worldwide. In advanced cases of lung cancer, a multimodality approach is often applied, however with poor local control rates. In early non-small cell lung cancer (NSCLC), surgery is the standard of care. Only 15-30% of patients are eligible for surgical resection. Improvements in imaging and treatment delivery systems have provided new tools to better target these tumors. Stereotactic body radiation therapy (SBRT) has evolved as the next best option. The role of radiofrequency ablation (RFA) is also growing. Currently, it is a third-line option in stage 1 NSCLC, when SBRT cannot be performed. More recent studies have demonstrated usefulness in recurrent tumors and some authors have also suggested combination of RFA with other modalities in larger tumors. Following the National Lung Screening Trial (NLST), screening by low-dose computed tomography (CT) has demonstrated high rates of early-stage lung cancer detection in high-risk populations. Hence, even considering the current role of RFA as a third-line option, in view of increasing numbers of occurrences detected, the number of potential RFA candidates may see a steep uptrend. In view of all this, it is imperative that interventional radiologists be familiar with the techniques of lung ablation. The aim of this article is to discuss the procedural technique of RFA in the lung and review the current evidence regarding RFA for NSCLC. PMID:27081229

Lung carcinogenesis is strongly influenced by environmental and heritable factors. The genetic contribution to the different histologies is unknown. A population-based computerized genealogy resource linked to a statewide cancer registry of lung cancer cases (n=5408) was analyzed to evaluate the heritable contribution to lung cancer histology in smoking (n=1751) and non-smoking cases (n=818). Statistical methods were used to test for significant excess relatedness of lung cancer cases. Significant excess distant relatedness was observed for all lung cancer histology subgroups analyzed except the small cell lung cancer subset (p=0.213). When smoking and non-smoking histologic subsets of lung cancer were considered, excess relatedness was observed only in non-smoking NSCLC (n=653; p=0.026) and, particularly, in those non-smokers with non-squamous histology (n=561; p=0.036). Sixty one pedigrees were identified which demonstrated a significant excess risk of non-smoking, non-squamous lung cancer cases; and an excess of female cases was observed among the cases in these high-risk pedigrees. This analysis supports a genetic predisposition to lung cancer carcinogenesis in non-smoking, non-squamous NSCLC cases. Copyright © 2018 International Association for the Study of Lung Cancer.

From March 1991 to October 1992, 41 patients with advanced non-small cell lung cancer (NSCLC) (20 stage IIIB and 21 stage IV) received a regimen consisting of cisplatin (CP) 100 mg/m2 i.v. days 1 and 8, and dipyridamole (DPD) 100 mg p.o. 75 minutes before CP, and then at hours 6, 12, and 18 as first-line chemotherapy. Cycles were repeated every 28 days for a total of 3. Median age was 56 years (range: 40-70). All patients had a performance status 0 to 1 and a weight loss < or = 10%. Squamous-cell carcinoma was diagnosed in 19 patients; adenocarcinoma in 16, and large-cell carcinoma in 6. A total of 37 patients were fully evaluable for response, whereas 39 were assessable for toxicity. No complete responses were observed: 5 patients (14%) achieved partial response; 23 patients (62%) showed no change, and progressive disease was observed in 9 (24%). The median time to treatment failure was 4 months, whereas median survival was 8 months. The average dose intensity received at the end of the third course of therapy was 46 mg/m2/week. There were no drug-related deaths. Toxicity was mild to moderate, with a high incidence of ototoxicity (54%) and emesis (67%). In conclusion, these results failed to demonstrate any significant advantage from a high-dose CP regimen modulated by DPD in patients with advanced NSCLC.

Cost-effectiveness analyses often inform healthcare reimbursement decisions. The preferred measure of effectiveness is the quality adjusted life year (QALY) gained, where the quality of life adjustment is measured in terms of utility. Areas covered: We assessed the availability and variation of utility values for health states associated with advanced or metastatic non-small cell lung cancer (NSCLC) to identify values appropriate for cost-effectiveness models assessing alternative treatments. Our systematic search of six electronic databases (January 2000 to August 2015) found the current literature to be sparse in terms of utility values associated with NSCLC, identifying 27 studies. Utility values were most frequently reported over time and by treatment type, and less frequently by disease response, stage of disease, adverse events or disease comorbidities. Expert commentary: In response to rising healthcare costs, payers increasingly consider the cost-effectiveness of novel treatments in reimbursement decisions, especially in oncology. As the number of therapies available to treat NSCLC increases, cost-effectiveness analyses will play a key role in reimbursement decisions in this area. Quantifying the relationship between health and quality of life for NSCLC patients via utility values is an important component of assessing the cost effectiveness of novel treatments.

To evaluate the feasibility and adherence to home delivery (HD) of pemetrexed maintenance treatment in patients with advanced non-squamous non-small cell lung cancer (nsqNSCLC). Exploratory, prospective, single-arm, Phase II study in advanced nsqNSCLC patients, with an Eastern Cooperative Oncology Group (ECOG) performance status of 0/1 that did not progress after 4 first-line induction cycles of a platinum doublet. The first cycle of pemetrexed (500mg/m(2)) was hospital administered, further cycles were HD until progressive disease or discontinuation. Feasibility was assessed by the adherence rate to HD (probability of reversion to hospital administration or treatment discontinuation due to HD) as primary endpoint, and by health-related quality-of-life (HRQoL: EQ-5D, lung cancer symptom scale [LCSS]), satisfaction with HD, overall survival (OS), and safety. 52 patients (UK & Sweden) received a median of 4 (range 1-19) pemetrexed maintenance cycles. Adherence rate up to Cycle 6 was 98.0% (95% confidence interval [CI]: 86.4%, 99.7%). All but 2 patients remained on HD. 1 patient discontinued after Cycle 1 (patient decision), and 1 after Cycle 6 (non-compliance with oral dexamethasone). 87% (33/38) of the patients preferred home to hospital treatment and in 90% (28/31) of cases, physicians were satisfied with distant management of patients. During HD Cycles 2-4 mean change from baseline ranged from 3.0 to 7.7 for EQ-5D visual analog scale. The 6-month OS rate was 73% (95% CI: 58%, 83%). 1 patient had an HD-related adverse event (device-related infection, Grade 2) and 1 patient died after Cycle 1, before HD, due to a possibly drug-related atypical pneumonia. HD of pemetrexed maintenance treatment in patients with advanced nsqNSCLC was feasible, safe, and preferred by patients, while maintaining HRQoL. Physicians were satisfied with distant patient management. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The isolation of circulating cell-free tumoral DNA (ctDNA) in plasma and its subsequent molecular analysis is a powerful tool that can help improve clinical outcomes across multiple cancer types, including non-small cell lung cancer (NSCLC). Assays of this nature that utilize blood as opposed to tumor samples are frequently referred to as liquid biopsies. An increasing number of new platforms have been recently developed that improve not only the fidelity of the molecular analysis of the liquid biopsy but also the number of tests performed on a single specimen. ctDNA assays for detection of both epidermal growth factor receptor (EGFR) sensitizing and resistance mutations have already entered clinical practice and many other molecular tests - such as resistance mutations for ALK rearrangements - are likely to do so in the near future. Due to an abundance of new evidence, an appraisal was warranted to review strengths and weaknesses, to describe what is already in clinical practice and what has yet to be implemented, and to highlight areas in need of further investigation. A multidisciplinary panel of experts in the field of thoracic oncology with interest and expertise in liquid biopsy and molecular pathology, was convened by the International Association for the Study of Lung Cancer (IASLC) to evaluate current available evidence with the aim of producing a set of recommendations for the use of liquid biopsy for molecular analysis in in guiding the clinical management of advanced NSCLC patients as well as identifying unmet needs.

Accurate determination of anaplastic lymphoma kinase (ALK) rearrangements is critical in identifying ALK-positive patients for targeted therapy in non-small-cell lung cancer (NSCLC). Fluorescence in situ hybridization (FISH) is the current standard method to detect ALK rearrangements but is technically challenging and costly. We compared optimised immunohistochemistry (IHC), quantitative real-time polymerase chain reaction (qRT-PCR) and fluorescence in situ hybridization techniques in this study of 139 samples of advanced NSCLC with non-squamous histology. ALK alteration was found in 32.6 % (43/132) of patients by FISH, 32.9 % (45/137) of patients by IHC and 27.9 % (34/122) of samples by qRT-PCR (concordance rate of 96.9 % between FISH and IHC, 95.7 % between FISH and qRT-PCR, P < 0.001). IHC sensitivity and specificity were 97.7 % and 96.6 %, respectively, while the sensitivity and specificity of qRT-PCR were 89.2 % and 98.7 %, respectively. ALK rearrangements were more common in young patients (P = 0.007), non-smokers or light smokers (P = 0.008) and adenocarcinoma histology, especially with signet ring cell features (P < 0.001). Optimised IHC could be a useful method in screening ALK rearrangements in clinical practice with qRT-PCR as an alternative diagnostic tool to clarify specific ALK variants.

Lung cancer has always been the leading cause of death among patients with malignant tumors, and the majority of these patients die because of cancer cell invasion and metastasis. Previous studies have implicated coiled-coil domain-containing protein 8 (CCDC8) as a tumor suppressor in several types of cancer, such as breast and prostate cancers. However, the expression levels or functions of CCDC8 in lung cancer have not been elucidated. Here, we used immunohistochemical staining to measure CCDC8 expression in 147 samples from tumors and 30 samples from the adjacent normal lung tissues of patients with non-small cell lung cancer. CCDC8 was shown to be located predominantly in the cytoplasm and partially on the cell membrane, and its expression level was significantly lower in lung cancer samples than that in the adjacent normal lung tissues (P=.001). CCDC8 expression was closely related to tumor differentiation (P=.039), tumor-node-metastasis stage (P=.009), lymph node metastasis (P=.038), and prognosis (P=.043) of lung cancer. Transfection of A549 cells with CCDC8 significantly reduced cell invasion and migration (P<.05), whereas the invasiveness and migration capacity in CCDC8-knockdown A549 cells were significantly increased in comparison with the control cells (P<.05). Furthermore, we demonstrated that CCDC8 can downregulate the expression of Snail and upregulate the expression of E-cadherin by inhibiting p-P38 and p-IκBα. Collectively, CCDC8 may suppress the invasion and metastasis of lung cancer cells, and it may represent a promising therapeutic target for non-small cell lung cancer. Copyright © 2016 Elsevier Inc.

The aim of this study was to assess the feasibility and treatment outcome of intensity modulated radiation therapy with simultaneous integrated boost (SIB-IMRT) in locally advanced non-small cell lung cancer (NSCLC) patients. A total of 64 NSCLC patients with stage IIB (3%), IIIA (36%), and IIIB (61%) were treated with concomitant (N = 47; 73%) or sequential (N = 9; 14%) chemotherapy between February 2009 and January 2014. Eight patients (13%) received RT alone. All patients received the same irradiation scheme using IMRT: prophylactic dose for mediastinum was 56 Gy at 1.65 Gy/fraction and SIB to macroscopic disease up to 68 Gy at 2 Gy/fraction. The median follow-up was 16 months (range, 1-70 months). The overall survival rate for all patients was 79% after 1 year and 46% after 2 years. Disease-free survival (DFS) was 81 and 45% after 1 and 2 years, respectively, resulting in a median DFS of 16 months. Multivariate analysis showed a statistically significant association between stage IIIB patients and a higher risk of mortality (HR 2.11; P = 0.019). In addition, T4 stage associated with higher risk of recurrence (HR 2.23; P = 0.024) while concomitant chemoradiation was associated with lower risk of any recurrence (HR 0.34; P = 0.004) No patient experienced grade ≥3 esophagitis and only 6 cases (9%) had grade 3 pneumonitis. Only having a higher lung volume was associated with higher risk of pneumonitis in the multivariate analysis (HR 16.21; P = 0.022). This study in advanced NSCLC patients shows that SIB-IMRT is an effective technique with acceptable toxicity, also when combined with chemotherapy.

Lung cancer remains the number one cause of cancer-related deaths worldwide with 221,200 estimated new cases and 158,040 estimated deaths in 2015. Approximately 80% of cases are non-small cell lung cancer (NSCLC). The diagnosis is usually made at an advanced stage where the prognosis is poor and therapeutic options are limited. The evolution of lung cancer is a multistep process involving genetic, epigenetic, and environmental factor interactions that result in the dysregulation of key oncogenes and tumor suppressor genes, culminating in activation of cancer-related signaling pathways. The past decade has witnessed the discovery of multiple molecular aberrations that drive lung cancer growth, among which are epidermal growth factor receptor (EGFR) mutations and translocations involving the anaplastic lymphoma kinase (ALK) gene. This has translated into therapeutic agent developments that target these molecular alterations. The absence of targetable mutations in 50% of NSCLC cases and targeted therapy resistance development underscores the importance for developing alternative therapeutic strategies for treating lung cancer. Among these strategies, pharmacologic modulation of the epigenome has been used to treat lung cancer. Epigenetics approaches may circumvent the problem of tumor heterogeneity by affecting the expression of multiple tumor suppression genes (TSGs), halting tumor growth and survival. Moreover, it may be effective for tumors that are not driven by currently recognized druggable mutations. This review summarizes the molecular pathology of lung cancer epigenetic aberrations and discusses current efforts to target the epigenome with different pharmacological approaches. Our main focus will be on hypomethylating agents, histone deacetylase (HDAC) inhibitors, microRNA modulations, and the role of novel epigenetic biomarkers. Last, we will address the challenges that face this old-new strategy in treating lung cancer.

Accumulating preclinical evidence suggests that anticancer immune responses contribute to the success of chemotherapy. The predictive significance of tumor-infiltrating lymphocytes (TILs) for response to neoadjuvant chemotherapy in non-small cell lung cancer (NSCLC) remains unknown. The aim of this study was to investigate the prognostic and predictive value of TIL subtypes in patients with advanced NSCLC treated with platinum-based chemotherapy. In total, 159 patients with stage III and IV NSCLC were retrospectively enrolled. The prevalence of CD3(+), CD4(+), CD8(+) and Foxp3(+) TILs was assessed by immunohistochemistry in tumor tissue obtained before chemotherapy. The density of TILs subgroups was treated as dichotomous variables using the median values as cutoff. Survival curves were estimated by the Kaplan-Meier method, and differences in overall survival between groups were determined using the Log-rank test. Prognostic effects of TIL subsets density were evaluated by Cox regression analysis. The presence of CD3(+), CD4(+), CD8(+), and FOXP3(+) TILs was not correlated with any clinicopathological features. Neither the prevalence of TILs nor combined analysis displayed obvious prognostic performances for overall survival in Cox regression model. Instead, higher FOXP3(+)/CD8(+) ratio in tumor sites was an independent factor for poor response to platinum-based chemotherapy in overall cohort. These findings suggest that immunological CD8(+) and FOXP3(+)Tregs cell infiltrate within tumor environment is predictive of response to platinum-based neoadjuvant chemotherapy in advanced NSCLC patients. The understanding of the clinical relevance of the microenvironmental immunological milieu might provide an important clue for the design of novel strategies in cancer immunotherapy.

Lung cancer is characterized by the highest incidence of solid tumor-related brain metastases, which are reported with a growing incidence during the last decade. Prognostic assessment may help to identify subgroups of patients that could benefit from more aggressive therapy of metastatic disease, in particular when central nervous system is involved. The recent sub-classification of non-small cell lung cancer (NSCLC) into molecularly-defined "oncogene-addicted" tumors, the emergence of effective targeted treatments in molecularly defined patient subsets, global improvement of advanced NSCLC survival as well as the availability of refined new radiotherapy techniques are likely to impact on outcomes of patients with brain dissemination. The present review focuses on key evidence and research strategies for systemic treatment of patients with central nervous system involvement in non-small cell lung cancer.

2017-01-01

The treatment paradigm for metastatic non-small cell, non-squamous lung cancer is continuously evolving due to new treatment options and our increasing knowledge of molecular signal pathways. As a result of treatments becoming more efficacious and more personalized, survival for selected groups of non-small cell lung cancer (NSCLC) patients is increasing. In this paper, three algorithms will be presented for treating patients with metastatic non-squamous, NSCLC. These include treatment algorithms for NSCLC patients whose tumors have EGFR mutations, ALK rearrangements, or wild-type/wild-type tumors. As the world of immunotherapy continues to evolve quickly, a future algorithm will also be presented. PMID:28373963

Spotlight on necitumumab in the treatment of non-small-cell lung carcinoma

Thakur, Manish K; Wozniak, Antoinette J

2017-01-01

The treatment options for metastatic non-small-cell lung cancer (NSCLC) have expanded dramatically in the last 10 years with the discovery of newer drugs and targeted therapy. Epidermal growth factor receptor (EGFR), when aberrantly activated, promotes cell growth and contributes in various ways to the malignant process. EGFR has become an important therapeutic target in a variety of malignancies. Small-molecule tyrosine kinase inhibitors (TKIs) of EGFR are being used to treat advanced NSCLC and are particularly effective in the presence of EGFR mutations. Monoclonal antibodies have also been developed that block the EGFR at the cell surface and work in conjunction with chemotherapy. Necitumumab is a second-generation fully human IgG1 monoclonal antibody that has shown promise in metastatic NSCLC. The benefit has mostly been restricted to squamous cell lung cancer in the frontline setting. Considering that the survival advantage for these patients was modest, there is a need to discover biomarkers that will predict which patients will likely have the best outcomes. This review focuses on the development and clinical trial experience with necitumumab in NSCLC. PMID:28293124

Objective To assess the cost-effectiveness of erlotinib versus supportive care (placebo) overall and within a predefined rash subgroup in elderly patients with advanced non-small-cell lung cancer who are unfit for chemotherapy and receive only active supportive care due to their poor performance status or presence of comorbidities. Setting Between 2005 and 2009, a total of 670 patients with non-small cell lung cancer (NSCLC) were randomised across 78 hospital sites (centres) in the UK. Participants 670 patients with pathologically confirmed stage IIIb-IV NSCLC, unfit for chemotherapy, predominantly poor performance status (>2 on Eastern Cooperative Oncology Group, ECOG) and estimated life expectancy of at least 8 weeks. Patients were followed until disease progression or death, including a subgroup of patients who developed first cycle rash. Interventions Patients were randomised (1:1) to receive best supportive care plus oral placebo or erlotinib (150 mg/day) until disease progression, toxicity or death. Primary outcome Overall survival (OS). Secondary outcomes Progression-free survival (PFS), tumour response and quality adjusted life years (QALY), including within prespecified subgroups. Results The mean incremental cost per QALY in all patients was £202 571/QALY. The probability of cost-effectiveness of erlotinib in all patients was <10% at thresholds up to £100 000. However, within the rash subgroup, the incremental cost/QALY was £56 770/QALY with a probability of cost-effectiveness of about 80% for cost-effectiveness thresholds between £50 000 to £60 000. Conclusions Erlotinib has about 80% chance of being cost-effective at thresholds between £50 000–£60 000 in a subset of elderly poor performance patients with NSCLC unfit for chemotherapy who develop first cycle (28 days) rash. Erlotinib is potentially cost-effective for this population, for which few treatment options apart from best supportive care are available. Trial

To analyze outcomes of stereotactic body radiotherapy (SBRT) for operable patients with early-stage non-small cell lung cancer (NSCLC) and to evaluate factors associated with outcomes. We retrospectively analyzed operable patients with NSCLC, staged as cT1-2N0M0, treated with SBRT between 2006 and 2015. Both biopsy-proven and clinically diagnosed NSCLC were included. Local control and survival rates were calculated and compared between subsets of patients. We investigated factors associated with outcomes. We identified 88 operable patients among 661 patients with cT1-2N0M0 NSCLC. The median age was 79 years (range: 55-88). The median follow-up time after SBRT was 40 months (range: 4-121). Fifty-nine patients had been pathologically diagnosed and the other 29 had been clinically diagnosed as having NSCLC. Local control, cause-specific survival (CSS) and overall survival (OS) at 3 years were 91%, 97% and 90% for T1, and 100%, 82% and 74% for T2, respectively. The CSS and OS at 3 years were 100% and 100% for GGO and 83% and 59% for solid tumors, respectively (p=0.005). On univariate analysis, age and T stage were significantly associated with CSS, and age, the Charlson Comorbidity Index (CCI), and opacity were significantly associated with OS. On multivariate analysis, age and CCI were significantly associated with OS. As for toxicities, Grades 0, 1, 2 and 3 radiation pneumonitis occurred in 37.5%, 47.7%, 13.6% and 1.1% of patients, respectively. No Grade 4 or 5 radiation pneumonitis occurred, and no other toxicities of Grade 2 or above were observed. Outcomes of SBRT for operable early stage NSCLC were as good as previous SBRT and surgery studies. Further investigation for selecting good SBRT candidates is warranted in high-risk operable patients. Copyright © 2017 Elsevier B.V. All rights reserved.

Non-small-cell lung cancer (NSCLC) is one of the leading causes of cancer deaths, both within the US and worldwide. There have been major treatment advances in NSCLC over the past decade with the discovery of molecular drivers of NSCLC, which has ushered in an era of personalized medicine. There are several actionable genetic aberrations in NSCLC, such as epidermal growth factor receptor and anaplastic lymphoma kinase (ALK). In 3%–7% of NSCLC, a chromosomal inversion event in chromosome 2 leads to fusion of a portion of the ALK gene with the echinoderm microtubule–associated protein-like 4 (EML4) gene. The constitutive activation of the ALK fusion oncogene renders it vulnerable to therapeutic intervention. This review focuses on the first-line treatment of advanced ALK-positive NSCLC using ALK inhibitors. Crizotinib was the first agent proven to be efficacious as first-line treatment for ALK-positive NSCLC. However, acquired resistance inevitably develops. The central nervous system is a sanctuary site that represents a common site for disease progression as well. Hence, more potent, selective next-generation ALK inhibitors that are able to cross the blood–brain barrier have been developed for treatment against crizotinib-resistant ALK-positive NSCLC and are also currently being evaluated for first-line therapy as well. In this review, we provide summary of the clinical experience with these drugs in the treatment of ALK-positive NSCLC. PMID:28210152

Treatment modalities for advanced ALK-rearranged non-small-cell lung cancer.

The ALK gene plays a key role in the pathogenesis of non-small-cell lung cancer (NSCLC). Patients with NSCLC harboring an ALK-rearrangement represent the second oncogene addiction to be identified in this disease. Crizotinib was the first ALK inhibitor showing pronounced clinical activity, and is now a reference treatment for ALK-positive NSCLC disease. However, despite initial impressive responses to crizotinib, acquired resistance almost invariably develops within 12 months. The pressing need for effective second-line agents has prompted the rapid development of next-generation ALK inhibitors. These agents, notably ceritinib and alectinib as the most developed, have a higher potency against ALK than crizotinib, along with activity against tumors harboring crizotinib-resistant mutations and potentially improved CNS penetration.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive procedure that has revolutionized the diagnosis and staging of lung cancer. The goal of the present study was to investigate the yield and applicability of molecular testing in the specimens obtained by EBUS-TBNA from patients with advanced non-small cell lung cancer (NSCLC), comparing the results with a series of patients who underwent diagnostic surgical procedures in the same institution. The study followed 306 consecutive patients with clinically diagnosed primary lung cancer who had the EBUS-TBNA procedure. EGFR and KRAS mutations were evaluated on cytologic specimens by Sanger sequencing and Cobas real-time polymerase chain reaction, whereas ALK rearrangement was tested by fluorescence in situ hybridization. The results were compared with those obtained from a series of 1,000 NSCLC surgical samples routinely analyzed. Molecular testing was possible in 96.9% of the samples obtained by EBUS-TBNA. EGFR (exons 18-21) mutations were found in 16.9%, KRAS mutation (exons 2-3) in 31.6%, and ALK rearrangement in 3.9% of the cases. In the surgical series, the mutations' distribution were 14.8%, 29.0%, and 3.4%, respectively. There were no statistical differences between the two series. Our study demonstrates that EBUS-TBNA can be effectively used not just for diagnosis but also for complete mutational testing. Copyright© by the American Society for Clinical Pathology.

Microparticles (MPs) are substantially increased in patients with operable stage non-small cell lung cancer (NSCLC) prior to lung resection surgery. This study tested the hypothesis that there is a decrease in MPs after surgical intervention. Between March 2012 and January 2015, 33 patients who had operable stage NSCLC were consecutively and prospectively enrolled into the study. Additionally, 31 healthy subjects who were consecutively enrolled in the study period served as age- and gender-matched controls. Circulating MPs (EDAc-MPs, EDAp-MPs, PDAc-MPs, PDAp-MPs) were measured by flow cytometry once in control subjects and twice (i.e., prior to and three months later after surgical intervention) in NSCLC patients. Compared with control subjects, these four types of circulating MPs were significantly higher in NSCLC patients prior to operation (all P < 0.005), but did not differ among the controls and NSCLC patients at 3 months after surgery (all P > 0.2). Additionally, a receiver operating characteristic curve (ROC) showed that these four types of MPs were significantly valuable predictors for detecting early stage NSCLC (all P < 0.004). Circulating MPs which were remarkably increased in the operable stage of NSCLC prior to surgery were substantially decreased 3 months later after surgery. These findings show that circulating MPs might be an accessory biomarker for monitoring those of NSCLC after receiving lung resection surgery.

Preoperative pulmonary function tests (PFTs) predict operative morbidity and mortality after resection in lung cancer. However, the impact of preoperative PFTs on overall outcomes in surgically-resected stage I and II non-small cell lung cancer (NSCLC) has not been well studied. This is a retrospective study of 149 patients who underwent surgical resection as first-line treatment for stage I and II NSCLC at a single center between 2003 and 2014. PFTs [forced expiratory volume in 1 sec (FEV1), Diffusing Capacity (DLCO)], both absolute values and percent predicted values were categorized into quartiles. The Kaplan-Meier method and Cox regression analysis were used to determine whether PFTs predicted for overall survival (OS). Logistic regression was used to estimate the risk of postoperative complications and length of stay (LOS) greater than 10 days based on the results of PFTs. The median age of the cohort was 68 years. The cohort was predominantly males (98.6%), current or ex-smokers (98%), with stage I NSCLC (82.76%). The majority of patients underwent a lobectomy (n=121, 81.21%). The predominant tumor histology was adenocarcinoma (n=70, 47%) followed by squamous cell carcinoma (n=61, 41%). The median follow-up of surviving patients was 53.2 months. DLCO was found to be a significant predictor of OS (HR=0.93, 95% CI=0.87-0.99; p=0.03) on univariate analysis. Although PFTs did not predict for postoperative complications, worse PFTs were significant predictors of length of stay >10 days. Preoperative PFTs did not predict for survival from resected early-stage NSCLC, but did predict for prolonged hospital stay following surgery.

Abnormal expression of microRNAs has been reported to regulate gene expression and cancer cell growth, invasion, and migration. Recently, upregulation of hsa-miR-1285 was demonstrated in bronchoalveolar lavage fluid samples from patients with lung cancer and downregulation in plasma level of stage-I lung cancer patients. However, the function and the underlying mechanism of miR-1285 in non-small-cell lung carcinoma have not been elucidated. In this study, we found that miR-1285-5p, the mature form of miR-1285, was significantly upregulated in human non-small-cell lung carcinoma cell lines A549 and SK-MES-1. Additionally, cells transfected with the miR-1285-5p inhibitor LV-anti-miR-1285-5p demonstrated significantly inhibited proliferation and invasion and depressed migration. Further analysis demonstrated that the miR-1285-5p precursor LV-miR-1285-5p attenuated the expression of Smad4 and cadherin-1 (CDH1) but that LV-anti-miR-1285-5p showed opposite results. A luciferase reporter assay confirmed that miR-1285-5p targeted Smad4 and CDH1. Mechanism analyses revealed that silence of Smad4 and CDH1 significantly attenuated the inhibitory effects of LV-anti-miR-1285-5p on non-small-cell lung carcinoma growth and invasion. Taken together, our data suggest that miR-1285-5p functions as a tumor promoter in the development of non-small-cell lung carcinoma by targeting Smad4 and CDH1, indicating a novel therapeutic strategy for non-small-cell lung carcinoma patients.

Lung cancer is one of the most common types of malignancies worldwide. The majority of patients are diagnosed with an incurable advanced/metastatic stage disease. Palliative treatment approaches improve the survival and the quality of life of these patients. Lung cancer is subdivided according to histology and molecular biology. The most important classification separates small cell from non-small cell lung cancer. In the subgroup of non-small cell lung cancer novel treatment approaches coming along with an improved prognosis have been established during the last decade. The current manuscript provides an overview on current treatment options for metastatic lung cancer. Furthermore, an outlook on promising future treatment options is provided.

Patients receiving stereotactic body radiotherapy for stage I non-small cell lung cancer are typically staged clinically with positron emission tomography-computed tomography. Currently, limited data exist for the detection of occult hilar/peribronchial (N1) disease. We hypothesize that positron emission tomography-computed tomography underestimates spread of cancer to N1 lymph nodes and that future stereotactic body radiotherapy patients may benefit from increased pathologic evaluation of N1 nodal stations in addition to N2 nodes. A retrospective study was performed of all patients with clinical stage I (T1-2aN0) non-small cell lung cancer (American Joint Committee on Cancer, 7th edition) by positron emission tomography-computed tomography at our institution from 2003 to 2011, with subsequent surgical resection and lymph node staging. Findings on positron emission tomography-computed tomography were compared to pathologic nodal involvement to determine the negative predictive value of positron emission tomography-computed tomography for the detection of N1 nodal disease. An analysis was conducted to identify predictors of occult spread. A total of 105 patients with clinical stage I non-small cell lung cancer were included in this study, of which 8 (7.6%) patients were found to have occult N1 metastasis on pathologic review yielding a negative predictive value for N1 disease of 92.4%. No patients had occult mediastinal nodes. The negative predictive value for positron emission tomography-computed tomography in patients with clinical stage T1 versus T2 tumors was 72 (96%) of 75 versus 25 (83%) of 30, respectively ( P = .03), and for peripheral versus central tumor location was 77 (98%) of 78 versus 20 (74%) of 27, respectively ( P = .0001). The negative predictive values for peripheral T1 and T2 tumors were 98% and 100%, respectively; while for central T1 and T2 tumors, the rates were 85% and 64%, respectively.

S-1 is a new oral fluoropyrimidine formulation that comprises tegafur, 5-chloro-2,4-dihydroxypyridine, and potassium oxonate. S-1 is designed to enhance antitumor activity and to reduce gastrointestinal toxicity. Several studies have demonstrated that both S-1 monotherapy and S-1 combination regimens showed encouraging efficacies and mild toxicities in the treatment of lung squamous cell carcinoma and adenocarcinoma. However, it is unclear whether S-1 can be used as standard care in advanced non-small cell lung cancer (NSCLC). The purpose of this meta-analysis was to assess the efficacy and safety of S-1-based chemotherapy, compared with standard chemotherapy, in patients with locally advanced or metastatic NSCLC. Thirteen randomized controlled trials (RCTs) involving 2,134 patients with a similar ratio of different pathological types were included. In first-line or second-line chemotherapy, compared with standard chemotherapy, S-1-based chemotherapy showed similar efficacy in terms of median overall survival (mOS), median progression free survival (mPFS), and objective response rate (ORR) (all P > 0.1), and significantly reduced the incidence of grade ≥ 3 hematological toxicities. In patients with locally advanced NSCLC receiving concurrent chemoradiotherapy, compared with standard chemoradiotherapy, significantly improved survival in the S-1-based chemotherapy was noted in terms of mOS and mPFS (risk radio [RR] = 1.289, P = 0.009; RR = 1.289, P = 0.000, respectively) with lower incidence of grade ≥ 3 neutropenia (RR = 0.453, P = 0.000). The present meta-analysis demonstrates that S-1-based chemotherapy shows similar benefits in advanced NSCLC and improves survival in locally advanced NSCLC, compared with standard treatment.

Detection of EGFR mutations with mutation-specific antibodies in stage IV non-small-cell lung cancer

PubMed Central

2010-01-01

Background Immunohistochemistry (IHC) with mutation-specific antibodies may be an ancillary method of detecting EGFR mutations in lung cancer patients. Methods EGFR mutation status was analyzed by DNA assays, and compared with IHC results in five non-small-cell lung cancer (NSCLC) cell lines and tumor samples from 78 stage IV NSCLC patients. Results IHC correctly identified del 19 in the H1650 and PC9 cell lines, L858R in H1975, and wild-type EGFR in H460 and A549, as well as wild-type EGFR in tumor samples from 22 patients. IHC with the mAb against EGFR with del 19 was highly positive for the protein in all 17 patients with a 15-bp (ELREA) deletion in exon 19, whereas in patients with other deletions, IHC was weakly positive in 3 cases and negative in 9 cases. IHC with the mAb against the L858R mutation showed high positivity for the protein in 25/27 (93%) patients with exon 21 EGFR mutations (all with L858R) but did not identify the L861Q mutation in the remaining two patients. Conclusions IHC with mutation-specific mAbs against EGFR is a promising method for detecting EGFR mutations in NSCLC patients. However these mAbs should be validated with additional studies to clarify their possible role in routine clinical practice for screening EGFR mutations in NSCLC patients. PMID:21167064

Changes in WIFI expression, an extracellular inhibitor of Wnt pathway, in non-small cell lung carcinomas were analyzed. Frequent (67% cases) suppression of WIFI transcript in non-small cell lung carcinomas were found. Our results, together with previously published data, suggest that inhibition of WIFI expression often occurs in squamous cell carcinomas and is less typical of adenocarcinomas. It was also found that a decrease in the WIFI transcript in tumors is parallel to concomitant suppression of the WIFI protein level. Our results provide further evidence that the WIFI suppression is a frequent event in the lung carcinogenesis, which might lead to disregulation of Wnt signaling pathway and contribute to tumor progression.

Cost-effectiveness of gemcitabine in stage IV non-small cell lung cancer: an estimate using the Population Health Model lung cancer module.

Statistics Canada (Ottawa, Ontario, Canada) is in the process of developing the Population Health Model to simulate the health and common illnesses of Canadians. The Population Health Model incorporates a lung cancer module that is based on contemporary Canadian practice. This microsimulation model can be used to estimate the total direct care costs of treating all lung cancer cases diagnosed in Canada and to evaluate the cost and cost-effectiveness of new therapeutic interventions as they are introduced into practice. Gemcitabine, a new nucleoside analogue with a broad spectrum of antitumor activity, is about to be introduced on the Canadian market. The Population Health Model has been used to estimate the cost-effectiveness of gemcitabine in the management of lung cancer over a range of drug doses per treatment cycle starting at 1,000 mg/m2 weekly x 3, as well as potential survival benefits. The survival of stage IV non-small cell lung cancer (NSCLC) patients treated on an international trial of gemcitabine (EO-18) was used to estimate the potential survival gain relative to the survival of stage IV NSCLC patients managed with best supportive care on a randomized trial conducted by the National Cancer Institute of Canada (BR 5). Sensitivity analyses were performed assuming that the survival gain was 25% or 50% less than that reported in the EO-18 trial. The perspective of the economic analysis is that of the government as payer in a universal health care system, and all costs are expressed in 1993 Canadian dollars. Based on the apparent survival advantage of the EO-18 trial in comparison to best supportive care, the cost per life-year gained ranged from $632 to $9,285, depending on the dose per treatment cycle. At the highest dose per cycle (2,000 mg/m2) and with survival reduced by 50% as compared with the EO-18 result, the cost per life-year gained was estimated to be $17,390. From these estimates of direct care costs in the Canadian health care system

Brain metastasis in non small cell lung cancer (NSCLC) patients is often considered as a terminal stage of advanced disease. Crizotinib is a small-molecule tyrosine kinase inhibitor (TKI) for ALK-rearranged NSCLC patients. Herein, we conducted a retrospective study to explore how Crizotinib affects the control of brain metastases and the overall prognosis in advanced ALK-rearranged NSCLC patients with brain metastases in Chinese population. A total of 34 patients were enrolled, of whom 20 (58.8%) patients had baseline brain metastases before Crizotinib treatment. Among patients with brain metastases before Crizotinib, overall survival (OS) after brain metastases was significantly longer than that of patients with brain metastases after Crizotinib (median OS, not reached vs. 10.3 months, respectively, p = 0.001). There was also a significant difference in systemic progression-free survival (PFS) between patients developing brain metastases before and after Crizotinib treatment (21.2 months vs. 13.9 months, p = 0.003). In conclusion, ALK-rearranged NSCLC patients with brain metastases before Crizotinib may benefit more from Crizotinib than those developing brain metastases during Crizotinib treatment.

Forkhead box F2 (FOXF2) is relatively limited to the adult lung, but its contribution to non-small cell lung cancer (NSCLC) prognosis is unclear. FOXF2 mRNA levels in NSCLC were lower than that in paired normal lung tissues (P = 0.012). The FOXF2low patients had shorter survival time than the FOXF2high patients (P = 0.024) especially in stage I (P = 0.002), chemotherapy (P = 0.018) and < 60 age groups (P = 0.002). Lower FOXF2 mRNA levels could independently predict poorer survival for patients with NSCLC (HR = 2.384, 95% CI = 1.241-4.577; P = 0.009), especially in stage I (HR =4.367, 95% CI =1.599-11.925; P = 0.004). The two independent datasets confirmed our findings. We examined FOXF2 mRNA levels in 84 primary NSCLC and 8 normal lung tissues using qRT-PCR. Rank-sum tests and chi-square tests were used to assess the differences among groups with various clinicopathological factors. Kaplan-Meier tests were used to compare survival status in patients with different FOXF2 mRNA levels. Cox proportional hazards regression model was used to evaluate the predictive value of FOXF2 mRNA level in NSCLC patients. Independent validation was performed using an independent dataset (98 samples) and an online survival analysis software Kaplan-Meier plotter (1928 samples). Our results demonstrated that decreased FOXF2 expression is an independent predictive factor for poor prognosis of patients with NSCLC, especially in stage I NSCLC.

The Italian Association of Thoracic Oncology (AIOT) and the European Thoracic Oncology Platform (ETOP) realized the first conjunct educational meeting, open to European oncologists involved in the treatment of thoracic malignancies, entitled "Advanced non-small cell lung cancer: new perspectives in first-line setting". The educational meeting included 8 interactive talks, held by European key opinion leaders, and 5 related clinical cases in which the attendees, divided in working tables based on their country origin, were involved for interactive discussion. The aim of this course was to elucidate the differences or similarities among the European countries in the first-line treatment of patients affected by advanced non-small cell lung cancer (NSCLC). Twenty-two attendees of the following countries participated: Austria, France, Italy, Spain, Swiss, and UK. As expected, some discrepancies between the groups were identified concerning the approach to the diagnostic phase, the choice of first-line regimen, the duration of treatment and the use of maintenance therapy. These discrepancies were mainly due to familiarity with specific therapies and lack of access to certain therapies due to local regulatory issues. The European Medicine Agency grants marketing of drugs in all Europe, regulatory agency of each country can register the drug, but can also deny public reimbursement thus restricting the options of the oncologist. The European Oncology Associations should join to their effort to achieve a uniform access to the cancer therapy for all patients in Europe. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.
