Objective: To study the relationship between of serum concentrations of CYFRA21-1 and to pathological staging in patients with non-small cell lung cancer. Methods: Serum concentrations of CYFRA21-1 were determined with IRMA in 224 patients with non-small cell lung cancer. Results: The serum CYFRA21-1 levels in patients with non-small cell lung carcinoma increased gradually as the tumor size enlarged. Levels in patients of T2 and T3 stages were significantly higher than those in patients of T1 stage, but the difference between those in patients of T2 stage and T3 stage were not significant. The serum CYFRA21-1 levels also increased as the number of lymph nodes with metastasis increased. Differences of serum levels of CYFRA21-1 in patients of consecutive lymph node stages were all significant. Conclusion: Preoperative detection of the serum concentration of CYFRA21-1 in patient with non-small cell lung cancer has important clinical significance on the judgement of T, N stages. (authors)

Primarily combined radiotherapy and chemotherapy are used to treat unresectable non-small-cell lung cancer; however, the results are not satisfactory. In this study treatment results were retrospectively analyzed and the prognostic factors related to survival were identified. From March 1999 to January 2004, 102 patients with stage IIIA/IIIB non-small-cell lung cancer received definitive radiotherapy with or without chemotherapy. Radiotherapy involved a daily dose of 1.8-2.0 Gy five times a week; 60 Gy was set as the total dose. Maximal chemotherapy was given to patients with normal kidney, liver, and bone marrow functions. The 5-year overall survival rate was 22.2%; the median survival was 18 months. The median follow-up of surviving patients was 53 months. The complete or partial response rate was 85%. At the time of the last follow-up, 21 patients were alive and 81 patients had died, including 5 patients who had died due to radiation pneumonitis. There were significant differences in survival and in the fatal radiation pneumonitis rate between patients with superior lobe lesions and those with middle or inferior lobe lesions. Patients whose primary tumor is located in the superior lobe appear to have a better clinical outcome.

Purpose: This study was performed to assess the smoking habits and changes in the cigarette smoking habits of patients prior to, at the time of and after the diagnosis of unresectable stage IIIA/IIIB non-small cell lung cancer. Methods: Patients with the diagnosis of unresectable stage IIIA/IIIB non-small cell lung cancer who had agreed to enter a phase III North Central Cancer Treatment Group Trial comparing twice daily thoracic radiation therapy (TRT) given with chemotherapy to once daily TRT given with chemotherapy were asked to fill out a questionnaire regarding their past and present cigarette smoking habits. This questionnaire included information regarding the number of years of smoking, number of packs of cigarettes smoked per day and the time frame of smoking history. Subsequently, patients were given questionnaires to assess changes in smoking history at the halfway point of treatment, and during follow-up visits. Results: Of the 140 patients who were entered on the above noted trial, 132 filled out baseline questionnaires and were the subject of this study. Of these 132 patients, 126 (95%) had either smoked cigarettes in the past or smoked at the time of study entry. The median pack years of smoking. (years of smoking x packs per day) was 43 with a range of 3-169 pack years. Of the 126 patients with a smoking history, 124 provided information regarding the status of their smoking at the time of entry on the study: 89 (72%) claimed to have quit smoking and, 35 (28%) reported that they continued to smoke an average of one pack per day. Of the 89 patients who had quit smoking, roughly one third had quit within the month before study entry and 45% had quit during the 8 month period prior to entry on the study. Of the 35 patients who continued to smoke at the time of entry on the study, 21 indicated that they stopped smoking during the period following randomization. Hence 10% of the original 140 patients entered on study continued to smoke an average of one

Full Text Available Background and objective Erlotinib is a targeted treatment for advanced non-small cell lung cancer. Smoking status may be one of influencing factors of the efficacy of erlotinib. The aim of this study is to explore the impact of smoking status on the efficacy of erlotinib in patients with advanced non-small cell lung cancer. Methods Patients with nonsmall cell lung cancer who had been previously treated with at least one course of platinum based chemotherapy received 150 mg oral doses of erlotinib once daily until disease progression. Response rate, progression-free survival, overall survival were analyzed in the different smoking status groups. Kaplan-Meier method was used to analyze the survival rate. Results Fortyeight patients were enrolled into the study from December 2005 to September 2006. We followed up these patients until 28th December, 2008. Median follow up time was 30 months. The compliance rate was 100%. The response rate was 32.1% in the smoking group and 35% in the never smoking group (P=0.836; The median progression-free survival was 3 months and 9 months, respectively (P=0.033. The median overall survival was 5 months and 17 months, respectively (P=0.162. Conclusion Erlotinib is an effective drug for advanced non-small cell lung cancer patients with different smoking status. Progressionfree survival is better in the never smoking patients than the smoking patients.

Exhaled breath contains thousands of gaseous volatile organic compounds (VOCs) that may be used as non-invasive markers of lung disease. The electronic nose analyzes VOCs by composite nano-sensor arrays with learning algorithms. It has been shown that an electronic nose can distinguish the VOCs pattern in exhaled breath of lung cancer patients from healthy controls. We hypothesized that an electronic nose can discriminate patients with lung cancer from COPD patients and healthy controls by analyzing the VOC-profile in exhaled breath. 30 subjects participated in a cross-sectional study: 10 patients with non-small cell lung cancer (NSCLC, [age 66.4+/-9.0, FEV(1) 86.3+/-20.7]), 10 patients with COPD (age 61.4+/-5.5, FEV(1) 70.0+/-14.8) and 10 healthy controls (age 58.3+/-8.1, FEV(1) 108.9+/-14.6). After 5 min tidal breathing through a non-rebreathing valve with inspiratory VOC-filter, subjects performed a single vital capacity maneuver to collect dried exhaled air into a Tedlar bag. The bag was connected to the electronic nose (Cyranose 320) within 10 min, with VOC-filtered room air as baseline. The smellprints were analyzed by onboard statistical software. Smellprints from NSCLC patients clustered distinctly from those of COPD subjects (cross validation value [CVV]: 85%; M-distance: 3.73). NSCLC patients could also be discriminated from healthy controls in duplicate measurements (CVV: 90% and 80%, respectively; M-distance: 2.96 and 2.26). VOC-patterns of exhaled breath discriminates patients with lung cancer from COPD patients as well as healthy controls. The electronic nose may qualify as a non-invasive diagnostic tool for lung cancer in the future.

Dendritic cells (DCs) are bone marrow-derived professional antigen presenting cells. Due to their role as potent inducers of immune responses, these cells are widely used as adjuvant in experimental clinical settings for cancer immune therapy. We have developed a DC-based vaccine using autologous......-small-cell-lung-cancer (NSCLC). In the present paper we retrospectively compare the maturation profile based on surface marker expression on DCs generated from the three patient cohorts and between cancer patient cohorts and a cohort of healthy donors.

Purpose : The effect of dose escalation of up to 6500 cGy on local control and survival was investigated in locally advanced non-small cell lung cancer. Materials and Methods : Ninety eight patients with biopsy-proven unresectable non-small cell lung cancer without distant metastases or medically inoperable patients with lower-stage were treated with definitive radiotherapy alone. Group A were treated by thoracic irradiation, 6000 cGy or less in total tumor dose with daily fractions of 180 to 200 cGy: and group B was treated with 6500 cGy of same daily fractions. Results : The actuarial overall survival rate for the entire group was 54% at 1 year, 26.6% at 2 years and 16.4% at 3 years with a median survival time of 13 months. Statistically significant prognostic factors that affect survival rate were stage and N-stage. However, no improvement in local control and survival has been seen with higher dose radiotherapy(group B). Conclusion : Dose escalation of up to 6500 cGy was no effect on local control and survival rate. To increase the survival rate of non-small cell lung cancer hyperfractionated radiotherapy or concurrent chemoradiotherapy should be considered

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

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.

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

We investigated the factors associated with post-recurrence survival and the treatment for non-small-cell lung cancer patients with postoperative distant recurrence, especially oligometastasis. We reviewed the data of 272 patients with distant recurrence who underwent resection of non-small-cell lung cancer from January 2000 through December 2011. The type of distant recurrence was classified as oligometastasis (n = 76, 28%) or polymetastasis (n = 196, 72%). Forty-seven (62%) patients with oligometastasis received local therapy (surgery 5, radiotherapy 9, sequential local and systemic therapy 28, chemoradiotherapy 5). Multivariate analysis revealed older age, non-adenocarcinoma, shorter disease-free interval, no pulmonary metastasis, liver metastases, bone metastases, and polymetastasis had significant associations with unfavorable post-recurrence survival. Subgroup analysis of patients with oligometastasis showed histology and disease-free interval had a great impact on survival. Smoking history and histology were associated with survival in patients with lung oligometastasis, whereas systemic treatment and longer disease-free interval were related to increased post-recurrence survival in those with brain oligometastasis. This study showed that an oligometastatic state per se was a significant favorable factor. Optimization of personalized systemic treatment and adding local treatment are important in the management of patients with non-small-cell lung cancer and oligometastasis. © The Author(s) 2015.

Background: Previous studies of patients with surgically resected non-small cell lung cancer and chest wall invasion have shown conflicting results with respect to prognosis. Whether high-risk subsets of the T3 N0 M0 population exist with respect to patterns of failure and overall survival has been difficult to ascertain, owing to small numbers of patients in most series. Methods and Materials: A retrospective review was performed to determine patterns of failure and overall survival for patients with completely resected T3 N0 M0 non-small cell lung cancer. From 1979 to 1993, 92 evaluable patients underwent complete resection for T3 N0 M0 non-small cell lung cancer. The following potential prognostic factors were recorded from the history: tumor size, location, grade, histology, patient age, use of adjuvant radiation therapy (18 of 92 patients), and type of surgical procedure (chest wall or extrapleural resection). Results: The actuarial 2- and 4-year overall survival rates for the entire cohort were 48% and 35%, respectively. The actuarial local control at 4 years was 94%. Neither the type of surgical procedure performed nor the addition of thoracic radiation therapy impacted local control or overall survival. Conclusion: Patients with completely resected T3 N0 M0 non-small cell lung cancer have similar local control and overall survival irrespective of primary location, type of surgery performed, or use of adjuvant radiation therapy. Additionally, the tumor recurrence rate and overall survival found in this study support the placement of this group of patients in Stage IIB of the 1997 AJCC lung staging classification

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

Cure in a patient with multiple osseus metastases in non-small cell lung cancer: a case report.

This case was reported to describe a case of cure in a 61-year old patient with squamous cell lung cancer and multiple extrathoracic metastasis. A left upper lobectomy of lung for a squamous cell carcinoma was performed on a 61-year old man with curative intent. Four months later two osseus metastases were irradiated with Cobalt 60 up to 40 Gy. The two irradiated lesions showed continuously shrinkage as well as signs of recalcification. Eleven years later the patient shows clinically absolute well being and on CT there are no signs of recurrent disease of the lung or bone anymore. To our knowledge has nobody so far reported of a case of as squamous cell lung cancer which was operated and irradiated on thus resulting in cure. Further on the authors discuss that it might well be worthwhile to define subgroups in stage 4 non-small cell lung cancer (presence of extrathoracic metastases) which might benefit from a more aggressive treatment approach than pure palliation.

Background: Platelet derived growth factor (PDGF) and PDGFR-β are expressed and have been found to have prognostic value in several human cancers. Data in non-small-cell cancer cell lines have suggested that PDGFR is a therapeutic target for drug development. In the current study PDGFR-β expression and prognostic value in small cell lung cancer (SCLC) was investigated. Methods and Materials: Paraffin-embedded tissue blocks from 53 patients with limited and extensive stage SCLC were obtained for immunohistochemical staining. Tumors from each patient were sampled 3 times and stained with PDGFR-β specific antibody. Patients were divided into low and high staining groups based on intensity. Results: There was high intensity PDGFR-β staining in 20 patients with SCLC. Another 29 expressed low intensity PDGFR-β staining, with only 4 patients showing no PDGFR-β staining. There was no statistically significant difference in 5 year overall survival between patients with low levels of PDGFR-β staining vs. those with high level staining SCLC tumors (p = 0.538). Conclusions: The present study found that the majority of SCLC patients express, at least, a low level of PDGF-β. However, the level of PDGFR-β expression was not a statistically significant predictor of 5 year overall survival in SCLC

This study was performed to clarify whether preoperative serum albumin level is related to the prognosis of non-small cell lung cancer patients undergoing surgical resection, and the relationships between serum albumin level and clinicopathological characteristics of lung cancer patients with emphysema or pulmonary fibrosis. We retrospectively evaluated 556 patients that underwent surgical resection for non-small cell lung cancer. The correlation between preoperative serum albumin level and survival was evaluated. Patients were divided into three groups according to the findings on chest high-resolution computed tomography (normal lung, emphysema, and pulmonary fibrosis), and the relationships between serum albumin level and clinicopathological characteristics, including prognosis, were evaluated. The cut-off value of serum albumin level was set at 4.2g/dL. Patients with low albumin levels (albumin emphysema group (n=48) and pulmonary fibrosis group (n=45) were significantly lower than that in the normal lung group (n=463) (p=0.009 and pulmonary fibrosis groups, but not in the emphysema group. Preoperative serum albumin level was an important prognostic factor for overall survival and recurrence-free survival in patients with resected non-small cell lung cancer. Divided into normal lung, emphysema, and pulmonary fibrosis groups, serum albumin level showed no influence only in patients in the emphysema group. Copyright © 2017 Elsevier B.V.

Full Text Available Fei-Yu Niu,1,2 Yi-Long Wu2 1Graduate School, Southern Medical University, Guangzhou, People’s Republic of China; 2Guangdong Lung Cancer Institute, Guangdong General Hospital, Guangdong Academy of Medical Sciences, Guangzhou, People’s Republic of China Abstract: Anaplastic lymphoma kinase (ALK rearrangement is an oncogene targeted with approved drugs second to epidermal growth factor receptor (EGFR in lung cancer. Crizotinib was developed and introduced into clinical practice rapidly and successfully after the discovery of ALK rearrangement in non-small-cell lung cancer. Chinese and other Asian patients treated with crizotinib seem to have lower toxicity and higher efficacy compared with other ethnicities. Crizotinib showed potent antitumor activity and manageable toxicity in mesenchymal–epithelial transition factor (c-Met/ROS1-positive non-small-cell lung cancer patients, but prospective clinical trials are still needed to confirm its efficacy and safety. Crizotinib appears to be effective against tumors originating from various organs that harbor ALK abnormalities. In the near future, we would classify the tumors by their genetic information beyond organs, such as ALKoma, EGFRoma, and RAFoma, and a single compound could be used for many different types of cancer in different organs. The major challenge of the widespread use of crizotinib in clinical practice is establishing convenient diagnostic techniques for the detection of ALK/c-Met/ROS1. In the present study, we reviewed the application of crizotinib in Chinese patients. Keywords: NSCLC, crizotinib, ALK, c-Met, ROS1

Treatment of elderly patients with stage IV non-small-cell lung cancer.

Every thoracic oncologist could be considered a geriatric oncologist as the median age of presentation with metastatic non-small-cell lung cancer is 71 years. Subgroup analyses and population-based studies suggest similar benefits to treatment of the fit elderly compared with younger patients. In 2011, a Phase III trial demonstrated the superiority of doublet chemotherapy over single-agent therapy for the elderly. For elderly patients there has been sufficient time to fully express any genetic predispositions, and the cumulative wear and tear, including the effects of cigarette smoke, can degrade performance status and impair organ function, leading some older patients to be less fit. Comprehensive geriatric assessment can augment the standard examination in defining the strengths and weakness of the elderly patient who is considering chemotherapy. In the future, biochemical assessment of physiologic age may further aid this assessment.

Surgery has been regarded as the standard treatment for patients with non-small cell lung cancer in the early stage, while radiotherapy has become an effective alternative for medically inoperable patients and those who refuse surgery. We reviewed the records of 31 patients with stage I-II non-small cell lung cancer treated by radiotherapy between 1980 and 1997. There were 15 patients in stage I and 16 in stage II. The variables analyzed for influence on cause-specific survival and loco-regional control were: age, performance status, clinical stage, tumor size, tumor site, radiation field, radiation dose, and combination with chemotherapy. The overall and cause-specific 1-, 2-, 3-, and 5-years survival rates were 71% and 77%; 63% and 73%; 34% and 48%; and 17% and 32%, respectively. Five-year survival rate for patients with peripheral tumor in the lung was 72%, with 70% loco-regional control, while the 5-year survival rate of patients whose tumor originated in the central region was 20%, with 25% loco-regional control. These differences had marginal significance on univariate analysis (P=0.07), but only tumor site (central vs peripheral) showed marginal significant influence on cause-specific survival (P=0.08) and loco-regional control (P=0.07) on multivariate analysis. There were no fatal complications, including radiation-induced myelopathy. The present series showed satisfactory results with definitive radiotherapy for patients with medically inoperable stage I-II non-small cell lung cancer, with results similar to those in recent reports of radiotherapy. The only significant variable was that patients with peripheral tumors had a better prognosis than patients with central tumors. (author)

1993-01-01

Purpose: This case was reported to describe a case of cure in a 61-year old patient with squamous cell lung cancer and multiple extrathoracic metastasis. Methods and materials: A left upper lobectomy of lung for a squamous cell carcinoma was performed on a 61-year old man with curative intent. Fourt months later two osseous metastases were irradiated with Cobalt 60 up to 40 Gy. Results: The two irradiated lesions showed continuously shrinkage as well as signs of recalcification. Eleven years later the patient shows clinically absolut well being and on CT there are no signs of recurrent disease of the lung or bone anymore. Discussion: To our knowledge has nobody so far reported of a case of a squamous cell lung cancer which was operated and irradiated on thus resulting in cure. Furtheron the authors discuss that it might well be worthwile to define subgroups in stage 4 non-small cell lung cancer (presence of extrathoracic metastases) which might benefit from a more aggressive treatment approach than pure palliation.

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 (Picotinib hydrochloride in the treatment of advanced NSCLC is efficacious and safe, and its toxic effects are tolerable.

Malignancy is an important predisposing factor for thromboembolic disease. Patients with malignancy display 4 to 10 times greater risk than the general population. As for lung cancer, that risk seems to further increase and become up to 20 times higher. The aim of this article is to review the International literature in order to highlight for the first time, the correlation between thromboembolic disease and small cell lung cancer. PubMed, Medline and Embase databases were searched from 1990 up to 2016, for retrospective and prospective studies that investigate the correlation between thromboembolic disease and small cell lung cancer. The incidence rate of thromboembolic disease found in these studies ranged between 6.8% and 11.5%. Thromboembolic disease is associated with a reduced survival in patients with small cell lung cancer and six factors seemed to increase the risk of thromboembolism: chemotherapy, cisplatin treatment, smoking, extensive disease, the infiltration of the superior vena cava and multiple concomitant diseases. Thromboembolic disease shows an increased incidence in patients with small cell lung cancer and more research with well-designed studies is required in order to study in detail the anticoagulation treatment and the survival in small cell lung cancer patients.

To examine the diagnostic accuracy of positron emission tomography/computed tomography in evaluating the mediastinum of patients with non-small cell lung cancer compared to histopathology results. The prospective study was conducted at the Department of Thoracic Surgery of the Pulmonary Hospital in Zakopane, Poland, from September 2008 to August 2012 and comprised patients with radiologically-suspected lung cancer. All patients underwent histological verification by either mediastinoscopy alone or thoracotomy with mediastinal lymphanedectomy. Computed tomography and positron emission tomography/computed tomography data sets were compared with the results of the histopathology examinations. There were 80 patients in the study. In the diagnosis of mediastinal lymph nodes, computed tomography was able to detect 9(11.25%) true-positive, 17(21.25%) false-positive, 40(50%) true-negative and 14(17.5%) false-negative cases. The sensitivity, specificity and accuracy of the method were found to be 39%, 70% and 61% respectively, while the positive and negative predictive values were 35% and 74%. Positron emission tomography/computed tomography yielded 15(18.75%) true-positive, 12(15%) false-positive, 46(57.5%) true-negative and 7(8.75%) false-negative cases. Sensitivity was 68% while specificity was 79%. The accuracy was 96%, and the positive and negative predictive values were 55% and 87% respectively. Positron emission tomography/computed tomography had higher diagnostic accuracy than computed tomography in assessing mediastinal lymph nodes of patients with non-small cell lung cancer. However, a positive test requires histopathology confirmation.

Risk factors and survival outcome for non-elective referral in non-small cell lung cancer patients--analysis based on the National Lung Cancer Audit.

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 �

Nontargeted Effect after Radiotherapy in a Patient with Non-Small Cell Lung Cancer and Bullous Pemphigoid

Directory of Open Access Journals (Sweden)

Carsten Nieder

2015-01-01

Full Text Available Purpose. To describe tumor shrinkage of nonirradiated lung metastases in a patient with non-small cell lung cancer. Case Report. The patient had a concurrent autoimmune condition, bullous pemphigoid, which was clinically exacerbated during radiotherapy of mediastinal and axillary lymph node metastases. He also developed a series of infections during and after irradiation, and we hypothesize that the immunological events during this phase might have influenced the size of the nonirradiated metastases. Conclusion. Ionizing radiation generates inflammatory signals and, in principle, could provide both tumor-specific antigens from dying cells and maturation stimuli that are necessary for dendritic cells’ activation of tumor-specific T cells. Even if the detailed mechanisms causing nontargeted immune modulatory effects in individual patients are poorly understood, clinical development of radioimmunotherapy is underway.

Pembrolizumab in the treatment of metastatic non-small-cell lung cancer: patient selection and perspectives

Full Text Available Ashwin Somasundaram, Timothy F Burns Division of Hematology/Oncology, Department of Medicine, University of Pittsburgh Cancer Institute, Pittsburgh, PA, USA Abstract: Lung cancer is the leading killer of both men and women in the US, and the 5-year survival remains poor. However, the approval of checkpoint blockade immunotherapy has shifted the treatment paradigm and provides hope for improved survival. The ability of non-small-cell lung cancer (NSCLC to evade the host immune system can be overcome by agents such as pembrolizumab (MK-3475/lambrolizumab, which is a monoclonal antibody targeting the programmed death 1 (PD-1 receptor. In early studies, treatment with pembrolizumab led to dramatic and durable responses in select patients (PD-L1+ tumors. This remarkable efficacy lead to approval of pembrolizumab in the second-line setting as response rates were almost doubled compared to standard of care (SOC chemotherapy. Most recently, data in the first-line setting from the KEYNOTE-024 study have redefined the SOC therapy for a selected subset of patients. In patients with ≥50% PD-L1+ tumors, pembrolizumab had a clear progression-free survival and overall survival benefit. Toxicity was mostly immune related and similar to checkpoint blockade toxicities observed in previous studies. The initial approval and subsequent studies of pembrolizumab required and utilized a companion diagnostic test, Dako’s IHC 22C3, to assess PD-L1 status of patients. The evaluation and scoring system of this assay has been used by other companies as a reference to develop their own assays, which may complicate selection of patients. Finally, the impact of pembrolizumab in NSCLC is growing as evidenced by the numerous, ongoing trials open for combinations with chemotherapy, chemoradiation, other immunotherapeutics, immunomodulators, tyrosine kinase inhibitors, PI3K inhibitors, MEK inhibitors, hypomethylating agents, and histone deacetylase inhibitors.

2014-01-01

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.

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.

In Cuba, lung cancer ranks second in incidence and first in mortality. Therefore, it is necessary to identify new therapeutical options. Immunological approaches are interesting because of the potential activity without the toxicities of conventional chemotherapy. The Center of Molecular Immunology developed a vaccine called Racotumomab; it acts on the lung carcinoma inducing an increase in tumor apoptosis and a decrease in the number of tumor vessels. A expanded access, multicenter, open study was conducted in 86 patients with non-small cell lung cancer in order to assess its safety. The administered dose was 1 mg/mL intradermically. The first 5 doses were administered every 14 days and the remaining 10 every 28 days until completing the treatment. The follow-up re immunizations were every 28 days. The occurrence of adverse events (AE) was analyzed and they were classified according to CTC v4.02 criteria. Adverse events were reported by 58 patients (67.4%), making a total of 215 events. burning at the injection site was the most frequently reported event, 32 (14.9%). The use of the vaccine in the patients under study showed good safety and tolerance

In the 1997 revision of the TNM staging system for lung cancer, patients with T3N0M0 disease were moved from stage IIIA to stage IIB since these patients have a better prognosis. Despite this modification, the local lymph node metastasis remained the most important prognostic factor in patients with lung cancer. The present study aimed to evaluate the prognosis of patients with T3N1 disease as compared with that of patients with stages IIIA and IIB disease. During 7-year period, 313 patients with non-small cell lung cancer (297 men, 16 women) who had resection were enrolled. The patients were staged according the 2007 revision of Lung Cancer Staging by American Joint Committee on Cancer. The Kaplan-Meier statistics was used for survival analysis, and comparisons were made using Cox proportional hazard method. The 5-year survival of patients with stage IIIA disease excluding T3N1 patients was 40%, whereas the survival of the patients with stage IIB disease was 66% at 5 years. The 5-year survival rates of stage III T3N1 patients (single-station N1) was found to be higher than those of patients with stage IIIA disease (excluding pT3N1 patients, P = 0.04), while those were found to be similar with those of patients with stage IIB disease (P = 0.4). Survival of the present cohort of patients with T3N1M0 disease represented the survival of IIB disease rather than IIIA non-small cell lung cancer. Further studies are needed to suggest further revisions in the recent staging system regarding T3N1MO disease.

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.

This analysis was conducted to evaluate the efficacy and safety of icotinib based regimens in treating patients with non-small cell lung cancer (NSCLC). Clinical studies evaluating the efficacy and safety of icotinib-based regimens with regard to response and safety for patients with NSCLC were identified using a predefined search strategy. Pooled response rates of treatment were calculated. With icotinib-based regimens, 7 clinical studies which including 5,985 Chinese patients with NSCLC were considered eligible for inclusion. The pooled analysis suggested that, in all patients, the positive reponse rate was 30.1% (1,803/5,985) with icotinib-based regimens. Mild skin itching, rashes and diarrhea were the main side effects. No grade III or IV renal or liver toxicity was observed. No treatment-related death occurred in patients treated with icotinib-based regimens. This evidence based analysis suggests that icotinib based regimens are associated with mild response rate and acceptable toxicity for treating Chinese patients with NSCLC.

It has been demonstrated that erlotinib is effective in treating patients with brain metastasis from non-small-cell lung cancer. However, the number of studies determining the erlotinib concentration in these patients is limited. The purpose of this study was to measure the concentration of erlotinib in the cerebrospinal fluid of patients with brain metastasis from non-small-cell lung carcinoma. Six patients were treated with the standard recommended daily dose of erlotinib (150 mg) for 4 weeks. All the patients had previously received chemotherapy, but no brain radiotherapy. At the end of the treatment period, blood plasma and cerebrospinal fluid samples were collected and the erlotinib concentration was determined by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The average erlotinib concentration in the blood plasma and the cerebrospinal fluid was 717.7±459.7 and 23.7±13.4 ng/ml, respectively. The blood-brain barrier permeation rate of erlotinib was found to be 4.4±3.2%. In patients with partial response (PR), stable disease (SD) and progressive disease (PD), the average concentrations of erlotinib in the cerebrospinal fluid were 35.5±19.0, 19.1±8.7 and 16.4±5.9 ng/ml, respectively. In addition, the efficacy rate of erlotinib for metastatic brain lesions was 33.3%, increasing to 50% in patients with EGFR mutations. However, erlotinib appeared to be ineffective in cases with wild-type EGFR. In conclusion, a relatively high concentration of erlotinib was detected in the cerebrospinal fluid of patients with brain metastases from non-small-cell lung cancer. Thus, erlotinib may be considered as a treatment option for this patient population. PMID:24649318

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

Full Text Available Non-small cell lung cancer (NSCLC accounts for the majority of all lung cancers. A 69-year-old female with postoperatively recurrent NSCLC was treated weekly with nanoparticle-albumin-bound paclitaxel (nab-paclitaxel monotherapy every 4 weeks as a tenth line chemotherapy, and stable disease was achieved by seven cycles of this regimen. The patient developed grade 4 neutropenia and grade 3 leukopenia, but none of the other toxicities, including febrile neutropenia and peripheral neuropathy, were severe, and thus she was able to tolerate this salvage chemotherapy. To our knowledge this is the first report of the efficacy of nab-paclitaxel monotherapy in a heavily treated NSCLC patient.

The aim of this study was to evaluate the therapeutic effect more accurately and predict the prognosis of treated non-small cell lung cancer by using contrast-enhanced magnetic resonance imaging (CE-MRI). Contrast-enhanced computed tomography (CE-CT) and CE-MRI were examined 90 non-small cell lung cancer patients treated with conservative therapies. Enhancement patterns of CE-MRI were classified into three types: peripheral; mottled; and homogeneous. Reduction ratio of tumor size (RRT) based on the World Health Organization response criteria and a new response rate; reduction ratio of viable tumor size (RRVT) which evaluates not only the reduction of tumor size but also changes in necrosis and/or cavity size, were evaluated. Changes of enhancement pattern were compared and correlated with pathological diagnosis. The RRTs, RRVTs, and interobserver agreements evaluated by all modalities were compared. The RRTs and RRVTs in each subgroup were correlated and compared with prognoses. Change of enhancement pattern depended on therapy had no tendency (p = 0.06). Enhancement pattern had significant correlation with pathological diagnosis (p < 0.0001). Partial response (PR) case of RRVT had significant difference between imaging techniques (p = 0.04). The RRVT of other cases and RRT had no significant difference. Interobserver agreements of RRT and RRVT were almost perfect (κ≥ 0.93). Prognosis had better correlation with RRVT than with RRT. Differences of relapse-free survival and survival between patients considered as having no change (NC) by RRT and PR by RRVT (NC-PR) and patients considered as having NC by RRT and RRVT were significant (p = 0.03, p = 0.01). There were no significant differences of relapse-free survival and survival between NC-PR patients and patients considered as having PR by RRT and RRVT. The CE-MRI technique could accurately evaluate the therapeutic effect and predict the prognosis of treated non-small cell lung cancer. (orig.)

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 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.

Full Text Available Patrick J Richard, Ramesh Rengan Department of Radiation Oncology, University of Washington, Seattle, WA, USA Abstract: The oligometastatic disease theory was initially described in 1995 by Hellman and Weichselbaum. Since then, much work has been performed to investigate its existence in many solid tumors. This has led to subclassifications of stage IV cancer, which could redefine our treatment approaches and the therapeutic outcomes for this historically “incurable” entity. With a high incidence of stage IV disease, non-small-cell lung cancer (NSCLC remains a difficult cancer to treat and cure. Recent work has proven the existence of an oligometastatic state in NSCLC in terms of properly selecting patients who may benefit from aggressive therapy and experience long-term overall survival. This review discusses the current treatment approaches used in oligometastatic NSCLC and provides the evidence and rationale for each approach. The prognostic factors of many trials are discussed, which can be used to properly select patients for aggressive treatment regimens. Future advances in both molecular profiling of NSCLC to find targetable mutations and investigating patient selection may increase the number of patients diagnosed with oligometastatic NSCLC. As this disease entity increases, it is of utmost importance for oncologists treating NSCLC to be aware of the current treatment strategies that exist and the potential advantages/disadvantages of each.

To observe the effects of MVP chemotherapy combined with concurrent radiotherapy for stage IIIB-IV non-small cell lung cancer. Sixty-two patients with stage IIIB-IV non-small cell lung cancer were randomized into two groups, concurrent radiochemotherapy group and MVP che-motherapy group. All patients in two groups were treated with MVP regimen (mitomycin C 6 mg/m² on day 1, vindesine 2 mg/m² on days 1, 8, and cisplatin 80-100 mg/m²). Patients in concurrent radiochemotherapy group received concurrent radiotherapy (46-56 Gy in 5-6 weeks). All patients received 2-4 cycles of MVP chemotherapy. The response rate was 48.4% and 19.4% in concurrent radiochemotherapy group and MVP group respectively (P MVP group.. The results show that efficacy of MVP chemotherapy combined with concurrent radiotherapy is significantly higher than that of MVP chemotherapy alone for advanced non-small cell lung cancer.

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

We evaluated the efficacy of first-generation EGFR-tyrosine kinase inhibitors (TKIs; erlotinib, gefitinib, and icotinib in patients with non-small-cell lung cancer carrying insertions and T790M and S768I mutations in EGFR exon 20. Patients and methods: Patients carrying EGFR exon 20 insertion/T790M/S768I mutations and treated with EGFR-TKIs were evaluated from 2005 to 2014 in Zhejiang Cancer Hospital. The efficacy was evaluated using the Kaplan–Meier method and compared with the log-rank test. Results: Sixty-two patients with exon 20 insertion/T790M/S768I mutations were enrolled. Mutations including exon 20 insertions and T790M and S768I mutations were observed in 29, 23, and ten patients, respectively. In total, the response rate and median progression-free survival (PFS were 8.1% and 2.1 months, respectively. Patients with S768I mutation manifested the longest median PFS (2.7 months, followed by those with T790M (2.4 months and exon 20 insertions (1.9 months; P=0.022. Patients with complex mutations show a better PFS than those with single mutations (2.7 months vs 1.9 months; P=0.034. Conclusion: First-generation EGFR-TKIs are less effective in patients with exon 20 uncommon mutations than in those with common mutations. Patients with complex mutations benefited more from first-generation EGFR-TKIs than those with single mutations.

Lung cancer is the leading cause of cancer-related death worldwide. Treatment of non-small cell lung cancer has evolved tremendously over the past decade. Specifically, immune checkpoint inhibitors have become an increasingly interesting target of pharmacological blockade. These immune inhibitors have shown promising results in front-line therapy and after failure of multiple lines, as well as in monotherapy and combination with other therapies. Vaccination in non-small cell lung cancer is also an emerging field of research that holds promising results for the future of immunotherapy in non-small cell lung cancer. This review presents a concise update on the most recent data regarding the role of checkpoint inhibitors as well as vaccination in non-small cell lung cancer.

Fever is common in malignant tumors. We report an exceptional case of psychogenic fever in a patient with small cell lung cancer. This is the first case report of psychogenic fever in a patient with small cell lung cancer. A 61-year-old Chinese man diagnosed with small cell carcinoma on June 30, 2012, came to our department with a complaint of fever lasting more than 1 month. He had undergone chemoradiotherapy for lung cancer 6 months previously. After admission, his body temperature fluctuated in the range of 37 °C to 39 °C. Somatic symptoms associated with anxiety were obvious. A 24-item Hamilton Anxiety Scale was used to assess the patient’s condition. A score of 32 confirmed a diagnosis of severe anxiety. After a week of antianxiety treatment, the patient’s temperature returned to normal. Psychogenic fever is common in cancer patients and deserves more attention. Patients with psychogenic fever must be distinguished from patients with infectious fever (including neutropenic fever), and tumor fever. Additionally, antianxiety or antidepression treatment should be provided. A concern is that continual anxiety may adversely affect anticancer therapy

Less work on depression status has been done with family members of patients with non-small cell lung cancer (NSCLC). This study investigated depression status of patients and their family members; and the relationship of the depression status between these two groups. This cross-sectional study enrolled 194 patients diagnosed with non-small cell lung cancer as well as their family members. In this study, a self-administered General Information Questionnaire was used to collect general information and the Self-rating Depression Scale (SDS) to assess depression status. Linear correlation analysis was used to probe the relationship of the depression status between patients and their family members. Of the 194 patients, 148 (76.3%) showed symptoms of depression. 148 (76.3%) family members had depression symptoms. The severity of depression in patients was positively correlated with that of family members (r = 0.577, p family members suffered depression, and the two were correlated. A prospective study might prove helpful in determining the real relationship existing between the two groups' mental status and whether early detection and intervention might ameliorate this current situation.

Purpose: Amifostine can reduce the cytotoxic effects of chemotherapy and radiotherapy in patients with locally advanced non-small-cell lung cancer, but concerns remain regarding its possible tumor-protective effects. Studies with sufficient statistical power to address this question are lacking. Methods and Materials: We performed a meta-analysis of all published clinical trials involving locally advanced non-small-cell lung cancer patients treated with radiotherapy with or without chemotherapy, who had been randomized to treatment with amifostine vs. no amifostine or placebo. Random effects estimates of the relative risk of overall, partial, and complete response were obtained. Results: Seven randomized trials involving 601 patients were identified. Response rate data were available for six studies (552 patients). The pooled relative risk (RR) estimate was 1.07 (95% confidence interval, 0.97-1.18; p = 0.18), 1.21 (95% confidence interval, 0.83-1.78; p = 0.33), and 0.99 (95% confidence interval, 0.78-1.26; p = 0.95) for overall, complete, and partial response, respectively (a RR >1 indicates improvement in response with amifostine compared with the control arm). The results were similar after sensitivity analyses. No evidence was found of treatment effect heterogeneity across the studies. Conclusions: Amifostine has no effect on tumor response in patients with locally advanced non-small-cell lung cancer treated with radiotherapy with or without chemotherapy

Full Text Available Background and objective As other tumors, unresectabe lung cancer can cause many psychological problems to the patients, such as depression and anxiety. The present paper aims to evaluate the status of depression before and after knowing the state of illness in patients with non-small cell lung cancer of stage Ⅲ. Methods 43 casesof newly diagnosed non-small cell lung cancer (NSCLC with stage Ⅲ were enrolled in the study. All the patients were distributed into three groups and given different intervention, that was completely unknowing the state of illness (group A, partly knowing the state of illness (group B and completely knowing the state of illness (group C. Before and after knowing the state of illness, the depression status was assessed with the Hamilton depression rating scale for depression(HAMD. Results The mean total score of HAMD was unchanged both in group A and C, while significantly reduced in group B. The scores of anxiety somatization, cognitive disorder, retardation and feeling of despair were all significant lower in the group B after the patients partly knowing the state of illness, while the scores of sleep disorder was obviously higher in group C after the patients completely knowing the state of illness. The hypochondriasis was much severer in the group A, and in the group C, the score of suicidal idea became significantly higher after the patient knowing the diagnosis.Conclusion Depression is very common in the NSCLC patients with stage Ⅲ. Partly knowing the state of illness can obviously ameliorate the symptoms of depression, while completely knowing or completely unknowing the state of illness have no effect on relieving the patients' depression.

Full Text Available TERT is of great importance in cancer initiation and progression. Many studies have demonstrated the TERT polymorphisms as risk factors for many cancer types, including lung cancer. However, the impacts of TERT variants on cancer progression and treatment efficacy have remained controversial. This study aimed to investigate the association of TERT polymorphisms with clinical outcome of advanced non-small cell lung cancer (NSCLC patients receiving first-line platinum-based chemotherapy, including response rate, clinical benefit, progression-free survival (PFS, overall survival (OS, and grade 3 or 4 toxicity. Seven polymorphisms of TERT were assessed, and a total of 1004 inoperable advanced NSCLC patients treated with platinum-based chemotherapy were enrolled. It is exhibited that the variant heterozygote of rs4975605 showed significant association with a low rate of clinical benefit, and displayed a much stronger effect in never-smoking female subset, leading to the clinical benefit rate decreased from 82.9% (C/C genotype to 56.4% (C/A genotype; adjusted OR, 3.58; P=1.40×10(-4. It is also observed that the polymorphism rs2736109 showed significant correlation with PFS (log-rank P=0.023. In age > 58 subgroup, patients carrying the heterozygous genotype had a longer median PFS than those carrying the wild-type genotypes (P=0.002. The results from the current study, for the first time to our knowledge, provide suggestive evidence of an effect of TERT polymorphisms on disease progression variability among Chinese patients with platinum-treated advanced NSCLC.

Background The neoplasm is still a potential threat for breast, Non-Small Cell Lung (NSCL) and cervix cancer patients. Those gradually invade into other body organs, inducing complex pathological complications. Whereas, the anticancer drugs suppress the bone marrow, resulting serious hematological toxicities. Thus, the monocytic toxicity may the chance of infections, particularly in AID’s patients. Objective We aimed this retrospective study to investigate the monocytopenia induced by vinorelbine following chemotherapy in cancer patients. Patients and method A total 60 adult cancer patients were divided into two groups; Group-1 patients received the treatment of Vinorelbine alone while group 2 patients received Vinorelbine based combination chemotherapy. Result The overall comparison of mean monocyte count (×103 per μl) with time showed a significant statistical difference (p value <0.001) for G-I and no significant difference for G-II (p value <0.08). The independent comparison of mean values for two groups at every week confirms the non-significant statistical difference during all of the five weeks (p values 0.551, 0.112, 0.559, 0.372, 0.468 respectively). In addition of that, the comparison of mean values observed before therapy with that of week 4 (after therapy) showed significant difference in G-I (p value <0.001) and non-significant in G-II (p value 0.053). Conclusion Monocytopenia is induced in both of the chemotherapy protocols allows the clinical oncologists and consultant physicians to select either of the chemotherapy protocol. The therapeutic efficacy should constitute the intervening consideration to treat the breast, cervix and NSCL (Non-Small Cell Lung’s) cancers. PMID:27833519

Serum GRP78 as a Tumor Marker and Its Prognostic Significance in Non-Small Cell Lung Cancers: A Retrospective Study

2015-01-01

Full Text Available Introduction. Glucose-regulated protein 78 (78 kDa, GRP78, which is also known as immunoglobulin heavy chain binding protein (BIP, is a major chaperone in the endoplasmic reticulum (ER. The expression and clinical significance of GRP78 in the serum of non-small cell lung cancer patients have not yet been clearly described. The aims of the present study were to investigate the expression of GRP78 in the serum of non-small cell lung cancer patients, the relationships with clinicopathological parameters, and the potential implications for survival. Patients and Methods. A total of 163 peripheral blood samples from non-small cell lung cancer patients were prospectively collected at the Department of Thoracic Surgery, Fudan University Shanghai Cancer, China. Clinical characteristics data, including age, gender, stage, overall survival (OS time, and relapse-free survival (RFS time, were also collected. Serum GRP78 levels were measured using a commercially available ELISA kit. The associations between GRP78 levels and clinicopathological characteristics and survival were examined using Student’s t-test, Kaplan-Meier, or Cox regression analyses. Results. The mean ± standard error (SE value of GRP78 was 326.5 ± 49.77 pg/mL. This level was significantly lower compared with the level in late-stage non-small cell lung cancer patients (1227 ± 223.6, p=0.0001. There were no significant correlations with the clinicopathological parameters. No significant difference was found between high GRP78 expression and low GRP78 expression with regard to RFS (p=0.1585. However, the OS of patients with higher GRP78 expression was significantly poorer (p=0.0334. Conclusions. GRP78 was expressed in non-small cell lung cancer patients and was highly enriched in late-stage lung cancer. GRP78 may have an important role in the carcinogenesis of non-small cell lung cancer and may be a prognostic marker for non-small cell lung cancer.

Full Text Available Lung cancer is the most common form of cancer with the highest incidence worldwide. The mortality rates are highest in males and second highest in females, after breast cancer. The genetic predisposition to Non Small Cell Lung Cancer (NSCLC is still under investigation, however, studies have shown that the Epidermal Growth Factor Receptor (EGFR, a receptor tyrosine kinase is frequently over-expressed and activated to a phosphorylated state in NSCLC. The activity of EGFR in cancer cells results in the phosphorylation of downstream proteins that promote cell proliferation, invasion, metastasis, and inhibition of apoptosis. Targeting the EGFR pathway therefore constitutes a relevant strategy for cancer therapy. Gefitinib is a selective inhibitor of the EGFR tyrosine kinase and is indicated for the treatment of adult patients with locally advanced or metastatic NSCLC with activating mutations of EGFR-TK. From the pharmacoeconomic point of view gefitinib is dominant (more effective and less expensive compared to the alternatives. In conclusion, gefitinib is a treatment option for NSCLC tumors with a high clinical and economic value in the Italian setting.

Thoracic radiotherapy is a major treatment modality of stage III non-small cell lung cancer. The normal lung tissue is sensitive to radiation and radiation pneumonitis is the most important dose-limiting complication of thoracic radiation therapy. This study was performed to identify the clinical and dosimetric parameters related to the risk of radiation pneumonitis after definitive radiotherapy in stage III non-small cell cancer patients. The medical records were reviewed for 49 patients who completed definitive radiation therapy for locally advanced non-small cell lung cancer from August 2000 to February 2010. Radiation therapy was delivered with the daily dose of 1.8 Gy to 2.0 Gy and the total radiation dose ranged from 50.0 Gy to 70.2 Gy (median, 61.2 Gy). Elective nodal irradiation was delivered at a dose of 45.0 Gy to 50.0 Gy. Seven patients (14.3%) were treated with radiation therapy alone and forty two patients (85.7%) were treated with chemotherapy either sequentially or concurrently. Twenty-five cases (51.0%) out of 49 cases experienced radiation pneumonitis. According to the radiation pneumonitis grade, 10 (20.4%) were grade 1, 9 (18.4%) were grade 2, 4 (8.2%) were grade 3, and 2 (4.1%) were grade 4. In the univariate analyses, no clinical factors including age, sex, performance status, smoking history, underlying lung disease, tumor location, total radiation dose and chemotherapy were associated with grade ≥2 radiation pneumonitis. In the subgroup analysis of the chemotherapy group, concurrent rather than sequential chemotherapy was significantly related to grade ≥2 radiation pneumonitis comparing sequential chemotherapy. In the univariate analysis with dosimetric factors, mean lung dose (MLD), V20, V30, V40, MLDipsi, V20ipsi, V30ipsi, and V40ipsi were associated with grade ≥2 radiation pneumonitis. In addition, multivariate analysis showed that MLD and V30 were independent predicting factors for grade ≥2 radiation pneumonitis. Concurrent

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.

The 5-year survival for patients with resected stage II (N1) non-small cell lung cancer ranges from 40% to 55%. No data exist addressing the benefit of neoadjuvant therapy for patients with stage II disease. This is largely in part due to the lack of a reliable, minimally invasive method to assess hilar nodes. This study is aimed at determining the ability of fusion positron emission/computed tomography (PET/CT) to identify hilar metastases in patients with resected non-small cell lung cancer. A retrospective review of surgically resected patients with fusion PET/CT within 30 days of resection was performed. The sensitivity, specificity, positive predictive value, and negative predictive value for PET/CT in detecting hilar nodal metastases was calculated for a range of maximum standardized uptake values (SUVmax). Hilar nodes from patients with falsely positive PET/CT scans were analyzed for the presence of histoplasmosis. Additionally, the impact of hilar node size greater than 1 centimeter on the calculated values was assessed. There were 119 patients evaluated. The number of lymph nodes resected ranged from 1 to 12 (X=2.98). There was decreased sensitivity and increased specificity with higher SUVmax cutoff values. At the standard SUVmax value of 2.5, the sensitivity and specificity were only 48.5% and 80.2%. The addition of size of hilar node by CT led to a modest improvement in sensitivity at all SUVmax cutoff values. Fusion PET/CT lacks sensitivity and specificity in identifying hilar nodal metastasis in patients with resected non-small cell lung cancer. Further prospective studies assessing the utility of PET/CT versus alternative sampling techniques are warranted. Copyright © 2012 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Programmed death-ligand 1 (PD-L1) expression status is inadequate for indicating nivolumab in patients with non-small cell lung cancer (NSCLC). Because the baseline advanced lung cancer inflammation index (ALI) is reportedly associated with patient outcomes, we investigated whether the pretreatment ALI is prognostic in NSCLC patients treated with nivolumab. We retrospectively reviewed the medical records of all patients treated with nivolumab for advanced NSCLC between December 2015 and May 2016 at three Japanese institutes. Multivariate logistic regression and Cox proportional hazards models were used to assess the impact of the pretreatment ALI (and other inflammation-related parameters) on progression-free survival (PFS) and early progression (i.e., within 8 weeks after starting nivolumab). A total of 201 patients were analyzed; their median age was 68 years (range, 27-87 years), 67% were men, and 24% had an Eastern Cooperative Oncology Group (ECOG) performance status of 2 or higher. An ECOG performance status ≥2, serum albumin ALI ALI ALI was found to be a significant independent predictor of early progression in patients with advanced NSCLC receiving nivolumab, and may help identify patients likely to benefit from continued nivolumab treatment in routine clinical practice. © 2017 The Authors.

Intratumoral lung abscess is a secondary lung abscess that is considered to be fatal. Therefore, surgical procedures, although high-risk, have sometimes been performed for intratumoral lung abscesses. However, no studies have examined the surgical outcomes of non-small cell lung cancer patients with intratumoral lung abscesses. The aim of this study was to investigate the surgical and survival outcomes of non-small cell lung cancer patients with intratumoral lung abscesses. Eleven consecutive non-small cell lung cancer patients with intratumoral lung abscesses, who had undergone pulmonary resection at our institution between January 2007 and December 2015, were retrospectively analysed. The post-operative prognoses were investigated and prognostic factors were evaluated. Ten of 11 patients were male and one patient was female. The median age was 64 (range, 52-80) years. Histopathologically, 4 patients had Stage IIA, 2 patients had Stage IIB, 2 patients had Stage IIIA, and 3 patients had Stage IV tumors. The median operative time was 346 min and the median amount of bleeding was 1327 mL. The post-operative morbidity and mortality rates were 63.6% and 0.0%, respectively. Recurrence of respiratory infections, including lung abscesses, was not observed in all patients. The median post-operative observation period was 16.1 (range, 1.3-114.5) months. The 5-year overall survival rate was 43.3%. No pre-operative, intra-operative, or post-operative prognostic factors were identified in the univariate analyses. Surgical procedures for advanced-stage non-small cell lung cancer patients with intratumoral lung abscesses, although high-risk, led to satisfactory post-operative mortality rates and acceptable prognoses.

Neuropsychological tests were used to evaluate possible central nervous system dysfunction in patients treated with chemotherapy. Ninety-five patients with non-small cell lung cancer limited disease were randomized to either radiotherapy (2.8 Gyx15) or combination chemotherapy with cisplatin and etoposide. In order to evaluate cognitive functions three neuropsychological tests were applied: Trail Making, Benton Visual Retention Test and Verbal Learning. Changes in the patients' test scores before and after treatment were compared. The chemotherapy patients showed reduced performance on some of the neuropsychological tests compared to the radiotherapy group. This indicates a treatment related effect on the central nervous system, possibly caused by the combination chemotherapy.

Objective: To investigate the potential benefit of incorporating fluorodeoxyglucose positron e- mission tomography (FDG PET) to delineate tire gross tumor volume(GTV) in patients with non-small cell lung cancer (NSCLC) complicated with atelectasis who are to be treated with three-dimensional conformal radiation therapy (3DCRT). Methods: Fourteen patients histopathologically proven as having NSCLC with image diagnosed as complicated with various degrees were studied in this study. All patients were scanned with both thoracic CT and thoracic or whole body PET. The GTV was delineated basing on both CT image and PET image (CT-GTV, PET- GTV) and the volume of each GTV(designated CT-GTV and PET-GTV) was compared by 3DCRT plan. Results: Each paired CT-GTV and PET-GTV was different from each other. All patients' GTV was reduced to an average of 27 cm 3 (20.4%) with median CT-PET of 133 cm 3 (90-180 cm 3 ) and median PET-GTV of 106 cm 3 , with a in- crease of 16.9%, 22 cm 3 ). The reduction of PET-GTV was due to PET could so differ cancer-induced atelectasis from gross tumor that it reduced the tarbet volume and spared more surrounding normal tissues. Conclusions: The incorporation of FDG PET data with gross tumor delineation is able to improve the accuracy of 3DCRT for non-small cell lung cancer patients complicated with atelectasis. (authors)

Recent advances in the treatment of non-small cell and small cell lung cancer.

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

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.

Purpose: Study of the course of possible treatment-related cognitive impairment in patients with small cell lung cancer. Methods and Materials: Thirty-two consecutive patients with small cell lung cancer underwent successive neurologic and neuropsychologic examinations until 5 months after prophylactic cranial irradiation, and in their pretherapeutic condition were compared to matched controls. Patients with brain metastases were excluded from this study. Results: Neurologic examination revealed central nervous system (CNS) abnormalities only in the 14 patients with brain metastases. In the remaining patients, neuropsychologic tests showed clear differences between the pretherapeutic performance of patients and that of matched controls (p < 0.001), but no significant deterioration either during or after therapy (0.1 < p < 0.8). Conclusion: The difference between the pretherapeutic performance of patients and that of matched controls may indicate disease-related cognitive impairment. Within the observation period, no adverse effects of the used therapy were found. Our observations underline the importance of a pretherapeutic assessment in neurotoxicity research.

Full Text Available Background: Gefitinib, an epidermal growth factor receptor-tyrosine kinase inhibitor, represents a new treatment option for patients with advanced non-small-cell lung cancer (NSCLC. We analyzed the data of patients who received Gefitinib for NSCLC in a tertiary care center in South India. Materials and Methods: Sixty-three patients with advanced NSCLC who had received Gefitinib either after failure of conventional chemotherapy or were previously not treated as they were unfit or unwilling for conventional treatment were included in the analysis. Results: The median follow-up for the cohort was 311 days (range 11-1544 days. Median time to progression was 161 (range 9-883 days. Complete and partial remission was seen in 1 (2% and 6 (9% patients, respectively, with overall response rate of 11%. Twenty-four (38% patients had stable disease. Gefitinib was well tolerated with no significant side effects. Conclusion: Gefitinib shows anti-tumor activity in pretreated or previously untreated patients with advanced NSCLC. It has a favorable toxicity profile and is well tolerated. Gefitinib should be considered as a viable therapy in patients with NSCLC.

Non-small cell lung cancer (NSCLC) harboring a limited number of distant metastases, referred to as the oligometastatic state, has been indicated for surgery for the past several decades. However, whether the strategy of surgical treatment results in a survival benefit for such patients remains controversial. Experientially, however, thoracic surgeons often encounter long-term survivors among surgically resected oligometastatic NSCLC patients. In this article, the current situation of surgical approach and potential future perspective for oligometastatic NSCLC are reviewed.

Diabetes has been consistently linked to many forms of cancers, such as liver, colorectal, pancreatic, and breast cancer, however, the role of diabetes in outcome among cancer patients remains unclear. In this study, we retrospectively reviewed electronic medical records of 342 inpatients newly diagnosed with NSCLC referred by a teaching hospital cancer center in southern Taiwan between 2005 and 2007 to examine the effects of fasting glucose levels at time of cancer diagnosis on overall survival in patients with non-small cell lung cancer (NSCLC). All patients were followed up until the end of 2010. The Kaplan-Meier method was used to compare survival curves for patients with and without diabetes. The Cox proportional hazards model was used to estimate hazard ratios for the association between diabetes, other prognostic factors and patient survival. We observed that significant prognostic factors for poor overall survival in patients with NSCLC included older age, smoking, poor performance status, advanced stage (stage IIIB or IV), and no cancer-directed surgery treatment. Particularly, we identified that diabetic state defined by fasting blood glucose level ≥126 mg/dl was another independent prognostic factor for these patients. Compared with those who had normal range of fasting glucose level (70-99 mg/dl), patients with high fasting glucose level (≥126 mg/dl) had 69% excess risk of all-cause mortality in patients with NSCLC. Diabetes as indicated by elevated fasting blood glucose was independently associated with a significantly higher risk of all-cause mortality in patients with NSCLC, indicating that diabetes or hyperglycemia effectively controlled may present an opportunity for improving prognosis in NSCLS patients with abnormal glucose level.

Full Text Available Michael R Shafique, Lary A Robinson, Scott Antonia Department of Thoracic Oncology, H Lee Moffitt Cancer Center and Research Institute, Tampa, FL, USA Abstract: Lung cancer is the most common cancer worldwide and the most common cause of cancer-related death. Non-small-cell lung cancer comprises ~87% of newly diagnosed cases of lung cancer, and nearly one-third of these patients have stage III disease. Despite improvements in the treatment of stage IV lung cancer, particularly with the introduction and dissemination of checkpoint inhibitors, very little progress has been made in the treatment of stage III lung cancer. In this article, we discuss the general staging criteria and treatment options for stage III lung cancer. We review how concurrent radiation and chemotherapy can have immunomodulatory effects, supporting the rationale for incorporating immunotherapy into existing treatment paradigms. Finally, we discuss the results of the PACIFIC trial and implications for the treatment of stage III lung cancer. In the PACIFIC trial, adding durvalumab as a maintenance therapy following the completion of chemoradiotherapy improved progression-free survival in patients with locally advanced unresectable stage III lung cancer. On the strength of these results, durvalumab has been approved by the US Food and Drug Administration for use in this setting, representing the first advance in the treatment of stage III lung cancer in nearly a decade.

Patients with oligometastatic Non-Small Cell Lung Cancer (NSCLC) present a potential opportunity for curative therapy; however, the challenge remains the definitive treatment of their localized disease and ablation of their limited overt metastatic sites of disease. In selecting patients with oligometastatic NSCLC for definitive therapy, proper staging through radiographic studies, including PET and brain MRI, and the pathologic staging of the mediastinal lymph nodes and potential sites of metastatic disease, are critical. With that in mind, the available literature suggests that in highly selected patients with solitary metastases to the brain, adrenals and other organs, long term survival may be achieved with combined definitive therapy of both the primary lung tumor and the solitary metastatic site.

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

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

Analysis of prognostic factors in patients with non-small cell lung cancer treated conventional radical teleradiotherapy

Radical surgery is the treatment of choice in non-small cell lung cancer, however, only about 20-30% of patients with early stage of disease (stage I, II and possibly IIIA) qualify for it. For the remaining patients, unable to tolerate surgery because of underlying medial disease, advanced age, respiratory insufficiency, or those who refused to undergo operation, radiation therapy is a clinically accepted alternative. Five - year survival for patients receiving radical radiation treatment alone ranges from 12-32%. We reviewed the records of 227 patients with inoperable non-small cell lung cancer, treated in our Institute between 1970-1990. In our group: 40% patients have unresectable tumor, 21% had bad pulmonary function tests results, 15% had cardiac risk, 6% were over 76 years of age, and 18% refused to agree to surgery. Treatment was delivered using megavoltage irradiation in doses ranging from 60 to 72 Gy. The survival probability was calculated by the Kaplan-Meier method. Overall survival (OS) probability at two years was 34% and at five years - 10%. Two - years local control was observed in 54% and five-year in 41%. The disease - specific survival (DSS) rates at 2 and 5 years were 30% and 8% respectively. The significant favorable prognostic factor for DSS and OS were tumor size (T1,T2, N0) and early stage (I), no weight loss, and complete radiological regression of the tumor 8 weeks after irradiation. The significant favorable prognostic factors for local control were good performance status (over 80 points acc. to Karnofsky scale), no weight loss, early stage (I), and complete radiological regression of the tumor 8 weeks after irradiation. 1. New therapeutic strategies involving chemotherapy should be considered for larger tumors (T2, T3, N1, N2). 2. Patients with a good performance status and small tumor (T1N0, T2N0) would benefit most from treatment with radiation alone. (author)

Purpose: The present retrospective study assessed the role of proton beam therapy (PBT) in the treatment of patients with Stage II or III non-small-cell lung cancer who were inoperable or ineligible for chemotherapy because of co-existing disease or refusal. Patients and Methods: Between November 2001 and July 2008, PBT was given to 35 patients (5 patients with Stage II, 12 with Stage IIIA, and 18 with Stage IIIB) whose median age was 70.3 years (range, 47.4-85.4). The median proton dose given was 78.3 Gy (range, 67.1-91.3) (relative biologic effectiveness). Results: Local progression-free survival for Stage II-III patients was 93.3% at 1 year and 65.9% at 2 years during a median observation period of 16.9 months. Four patients (11.4%) developed local recurrence, 13 (37.1%) developed regional recurrence, and 7 (20.0%) developed distant metastases. The progression-free survival rate for Stage II-III patients was 59.6% at 1 year and 29.2% at 2 years. The overall survival rate of Stage II-III patients was 81.8% at 1 year and 58.9% at 2 years. Grade 3 or greater toxicity was not observed. A total of 15 patients (42.9%) developed Grade 1 and 6 (17.1%) Grade 2 toxicity. Conclusion: PBT for Stage II-III non-small-cell lung cancer without chemotherapy resulted in good local control and low toxicity. PBT has a definite role in the treatment of patients with Stage II-III non-small-cell lung cancer who are unsuitable for surgery or chemotherapy.

Full Text Available Background and objective The patients with non-small cell lung cancer (NSCLC might contract anemia, however, whether anemia is one of the independent prognostic factors to the patients with NSCLC is still controversial. So the aim of this study is to investigate the correlation between anemia and overall survival (OS in patients with NSCLC. Methods 1 018 patients with operable NSCLC were retrospectively analyzed in our hospital from January 2000 to December 2008. Results The occurrence of anemia before operation was 252/1 018 (24.1%. The OS in NSCLC patients without anemia was (2 425.98±50.03 days, and the OS in patients with anemia was (2 107.15±93.86 days. There was significant difference in the OS between them (P=0.001. The patients with anemia in stage I had shorter survival time than those without anemia (P < 0.001. But there was no difference in other stage patients. TNM stage, gender, tumor size and lymph nodes metastasis were correlated with OS using Cox regression analysis. Conclusion Anemia is correlated with survival in operable NSCLC patients. Moreover, it is an independent prognostic factor in NSCLC patients with stage I.

Thoracic surgery is a dynamic field, and many scientific, technological, technical, and organizational changes are occurring. A prominent example is the use of less invasive approaches to major resection of non-small cell lung cancer (NSCLC), both thoracoscopic and robotic. Sophisticated technology corroborated by clinical data has led to these approaches becoming accepted additions to the armamentarium. Additionally, improvements in perioperative pain management have also contributed to dramatically changing the experience of patients who undergo modern thoracic surgery. Lung cancer is being detected more often at an early stage. At the same time, advances in techniques, patient care, clinical science, and multidisciplinary treatment support an increased role for aggressive resection in the face of larger locally advanced tumors or for those with limited metastatic disease. These advances, conducted in the setting of multidisciplinary decision making, have resulted in real and palpable advancements for patients with lung cancer.

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 Raman spectroscopy can effectively identify patients with stage I, stage II or stage III/IV Non-Small Cell Lung cancer using patient serum samples.

Purpose: We retrospectively compared the survival rate in patients with non-small-cell lung cancer (NSCLC) treated with radiofrequency ablation (RFA), surgery, or chemotherapy according to lung cancer staging. Materials and Methods: From 2000 to 2004, 77 NSCLC patients, all of whom had WHO performance status 0–2 and were >60 years old, were enrolled in a cancer registry and retrospectively evaluated. RFA was performed on patients who had medical contraindications to surgery/unsuitability for surgery, such as advanced lung cancer or refusal of surgery. In the RFA group, 40 patients with inoperable NSCLC underwent RFA under computed tomography (CT) guidance. These included 16 patients with stage I to II cancer and 24 patients with stage III to IV cancer who underwent RFA in an adjuvant setting. In the comparison group (n = 37), 13 patients with stage I to II cancer underwent surgery; 18 patients with stage III to IV cancer underwent chemotherapy; and 6 patients with stage III to IV cancer were not actively treated. The survival curves for RFA, surgery, and chemotherapy in these patients were calculated using Kaplan–Meier method. Results: Median survival times for patients treated with (1) surgery alone and (2) RFA alone for stage I to II lung cancer were 33.8 and 28.2 months, respectively (P = 0.426). Median survival times for patients treated with (1) chemotherapy alone and (2) RFA with chemotherapy for stage III to IV cancer were 29 and 42 months, respectively (P = 0.03). Conclusion: RFA can be used as an alternative treatment to surgery for older NSCLC patients with stage I to II inoperable cancer and can play a role as adjuvant therapy with chemotherapy for patients with stage III to IV lung cancer.

Chemotherapy options for the elderly patient with advanced non-small cell lung cancer.

LENUS (Irish Health Repository)

Hennessy, B T

2012-02-03

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

Different Response to Nivolumab in a Patient with Synchronous Double Primary Carcinomas of Hypopharyngeal Cancer and Non-Small-Cell Lung Cancer

Directory of Open Access Journals (Sweden)

Teppei Yamaguchi

2017-09-01

Full Text Available Nivolumab is a humanized IgG4 and programmed death 1 (PD-1 monoclonal antibody that has demonstrated antitumor efficacy in clinical trials of various malignant tumors including non-small-cell lung cancer and head and neck squamous cell carcinoma (SCC. However, patients with multiple primary malignancies were excluded in clinical trials. Thus, the efficacy of nivolumab in such patients has not been revealed yet. The programmed death ligand 1 (PD-L1 expression level is currently the main predictive biomarker of PD-1 inhibitors in various types of solid tumors and hematological malignancies. Here we describe a patient with synchronous double primary carcinomas of hypopharyngeal SCC and lung adenocarcinoma who exhibited different responses to nivolumab. After nivolumab treatment, hypopharyngeal SCC with moderate PD-L1 positivity by immunohistochemical staining showed a remarkable response; conversely, nivolumab was not effective against lung adenocarcinoma, which was negative for PD-L1. This suggests that tumors with different PD-L1 expressions may exhibit different responses to PD-1 inhibitors when multiple primary malignancies are present within one patient.

Full Text Available Lung cancer disease diagnosis and treatment is costly. As the numbers of inflicted rise so does the economic burden assumed for this cancer type. When the treatment expenditures are considered for all types of cancer, the lung cancer is thought to occupy a 20% share. The disease examined in two basic groups as small-cell lung cancer and non-small cell lung cancer (NSCLC is the most frequently encountered type of its kind nationally and in the World. This study considers the cost, effectiveness and cost effectiveness of platinum based chemotherapy medications with active ingredients pemetrexed and gemcitabine used for NSCLC. A review of studies relevant to the advanced stage NSCLC where majority of patients are positioned is foreseen to be useful to the decision makers since policy makers, regulating authorities and physicians require more information due to increased overall finance and costs, as well as treatment cost effectiveness. Furthermore, due to the entry attempt of pemetrexed active ingredient to the list of reimbursed medications for the first stage lung cancer treatment, it is assumed that a review of studies containing pemetrexed and gemcitabine will draw the attention of decision makers at the Social Security Instutition.

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 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 ALI and SUVmax values (P = .436). The median survival time in patients with ALI 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.

Non-small cell lung cancer (NSCLC) is the most common lung cancer type and the most common cause of mortality in lung cancer patients. NSCLC is often associated with resistance to chemotherapeutics and together with rapid metastatic spread, results in limited treatment options and poor patient survival. NSCLCs are heterogeneous, and consist of epithelial and mesenchymal NSCLC cells. Mesenchymal NSCLC cells are thought to be responsible for the chemoresistance phenotype, but if and how this phenotype can be transferred to other NSCLC cells is currently not known. We hypothesised that small extracellular vesicles, exosomes, secreted by mesenchymal NSCLC cells could potentially transfer the chemoresistance phenotype to surrounding epithelial NSCLC cells. To explore this possibility, we used a unique human bronchial epithelial cell (HBEC) model in which the parental cells were transformed from an epithelial to mesenchymal phenotype by introducing oncogenic alterations common in NSCLC. We found that exosomes derived from the oncogenically transformed, mesenchymal HBECs could transfer chemoresistance to the parental, epithelial HBECs and increase ZEB1 mRNA, a master EMT transcription factor, in the recipient cells. Additionally, we demonstrate that exosomes from mesenchymal, but not epithelial HBECs contain the ZEB1 mRNA, thereby providing a potential mechanism for the induction of a mesenchymal phenotype in recipient cells. Together, this work demonstrates for the first time that exosomes derived from mesenchymal, oncogenically transformed lung cells can transfer chemoresistance and mesenchymal phenotypes to recipient cells, likely via the transfer of ZEB1 mRNA in exosomes. © 2017 UICC.

Objective:To detect the serum proteomic patterns of patients with non-small cell lung (NSCLC) treated with radiochemotherapy by surface enhanced laser desorption ionization time of flight mass spectrometry (SELDI-TOF-MS) protein chip array techniques, and to screen differential expression protein and observe the changes between the patterns before and after the treatment. Methods: SELDI-TOF-MS and CM-10 protein chips were used to detect the serum proteomic patterns of 35 healthy persons (normal control) and 35 patients with NSCLC before radiochemotherapy. Twenty-six out of the 35 patients after the treatment were also studied. BioMarker Wizard 3.01 and BioMarker Pattern System 5. 01 were used in combination to analyze the data and to develop diagnostic models. Results: Sixteen differential expression protein peaks from a total of 251 protein peaks were automatically chosen, including 8 high expressions and 8 low expressions in patients with NSCLC. Of the 16 protein peaks, 6 protein peak patterns ( M 2 572.1, M 2 885.8, M 3 870.4, M 4 161.4, M 5 739.7 and M 8 164.3 mass/charge ratio [ m/z] ) were observed in model that could be used to distinguish lung cancer' from non-cancer diseases. The sensitivity and specificity results were 91% (32/35)and 83% (29/35). When the SELDI marker pattern was tested with the blinded test set, the sensitivity and specificity were 80% (28/35) and 71% (25/35). The 16 differential expression protein peaks of patients before and after the treatment were obviously different. But the peaks of patients after the treatment trended to those of the normal control. Of the 16 protein peaks, M 2 572.1, M 2 885.8, M 4 664.78, M 9 228.39 and M 9 396.42 were significantly changed. Conclusions: SELDI-TOF-MS is possibly significant for screening differential expression proteins and assessing the treatment efficacy and prognosis of patients, which needs to be demonstrated by further study.

Enhancer of zeste homolog 2 (EZH2) is a histone methyltransferase that is deeply involved in cancer pathogenesis. Although clinicopathological significance of EZH2 in non-small cell lung cancer has been gradually elucidated, such significance in small cell lung cancer (SCLC) has yet to be fully investigated. Forty patients with resected SCLC were analyzed for EZH2. EZH2 expression was evaluated using the Allred score (0-8) and was classified into negative (0-6) and positive (7 and 8). We evaluated the association between EZH2 and the clinicopathological characteristics and postoperative survivals. Among 40 patients, 15 (37.5%) and 25 (62.5%) were classified as being negative and positive for EZH2, respectively. Fisher's exact test demonstrated no significant associations between the positivity for EZH2 and clinicopathological characteristics. No significant differences were observed in recurrence-free and overall survivals between EZH2-negative/low and EZH2-high patients. EZH2 was frequently observed in patients with resected SCLC, but no significant associations were found between its expression and the clinicopathological characteristics and postoperative survivals.

However, most of patients could not get the gene information for lack of enough tissues. To explore the tissue specimens alternatives is a hot spot in clinical work. This report reviews the tissue specimen alternatives of driver gene testing in non-small cell lung cancer.

Background Over the past decade, numerous reports describe the generation and increasing utility of non-small-cell lung cancer (NSCLC) patient-derived xenografts (PDX) from tissue biopsies. While PDX have proven useful for genetic profiling and preclinical drug testing, the requirement of a tissue biopsy limits the available patient population, particularly those with advanced oligometastatic disease. Conversely, ?liquid biopsies? such as circulating tumour cells (CTCs) are minimally invasive...

Purpose: Although palliative chemotherapy is the standard of care for patients with diagnoses of stage IV non-small cell lung cancer (NSCLC), patients with a small metastatic burden, “oligometastatic” disease, may benefit from more aggressive local therapy. Methods and Materials: We identified 186 patients (26% of stage IV patients) prospectively enrolled in our institutional database from 2002 to 2012 with oligometastatic disease, which we defined as 5 or fewer distant metastatic lesions at diagnosis. Univariate and multivariable Cox proportional hazards models were used to identify patient and disease factors associated with improved survival. Using propensity score methods, we investigated the effect of definitive local therapy to the primary tumor on overall survival. Results: Median age at diagnosis was 61 years of age; 51% of patients were female; 12% had squamous histology; and 33% had N0-1 disease. On multivariable analysis, Eastern Cooperate Oncology Group performance status ≥2 (hazard ratio [HR], 2.43), nodal status, N2-3 (HR, 2.16), squamous pathology, and metastases to multiple organs (HR, 2.11) were associated with a greater hazard of death (all P<.01). The number of metastatic lesions and radiologic size of the primary tumor were not significantly associated with overall survival. Definitive local therapy to the primary tumor was associated with prolonged survival (HR, 0.65, P=.043). Conclusions: Definitive local therapy to the primary tumor appears to be associated with improved survival in patients with oligometastatic NSCLC. Select patient and tumor characteristics, including good performance status, nonsquamous histology, and limited nodal disease, may predict for improved survival in these patients

Chemotherapy is the preferred treatment regimen for advanced lung cancer patients. This study investigated the health resources utilized by and medical expenses of patients with non-small cell lung cancer (NSCLC) as well as the influence of various chemotherapy regimens on the final medical costs in China. The aim of this study was to provide physicians with a reference to use as the basis for their choice of treatment. Data were collected from the Shanghai Chest Hospital's medical charts and billing database. The collected patient information included the baseline characteristics, medical history, chemotherapy regimens, and medical costs, which were used to estimate the health resources utilized by patients and the cost of treatment. This study included 328 patients, and the average total medical cost was $US14,165. This cost included drugs, which accounted for as much as 78.91% of the total cost, and chemotherapy drugs, which accounted for 51.58% of total drug expenses. The most frequently utilized chemotherapy drug was carboplatin, and the most expensive chemotherapy drug was erlotinib. In drug combinations, gemcitabine was utilized most frequently, the combination of gemcitabine and paclitaxel was the most expensive, and cisplatin was the least expensive drug. Epidermal growth factor receptor-positive patients were treated with targeted drug therapy (icotinib, erlotinib, and gefitinib). The use of recombinant human endostatin was often combined with a vinorelbine plus cisplatin regimen. Traditional Chinese medicines were the most frequently utilized non-chemotherapy drugs, and these drugs were also the most expensive. The final cost significantly depended on the specific chemotherapy regimen; thus, the rationale and cost of the chemotherapy regimen and adjuvant chemotherapy should be considered in patients with advanced NSCLC.

Cost inputs were derived from publicly available databases or from the published literature. Expert opinion was only used if no other source was available. Efficacy data from two randomized clinical trials were used. The time horizon in the health economic model was lifetime. Efficacy and costs were discounted by 3.5%. All main model parameters were tested in deterministic and probabilistic sensitivity analyses.Results: Mean incremental savings to society per patient ranged from €2277 in Italy to €4461 in Germany. The results were most sensitive to the change in proportion of patients working full-time and the proportion of patients who were able to return to work.Conclusion: This analysis shows that bevacizumab-based treatment in non-small-cell lung cancer is associated with more savings to society compared to standard chemotherapy in terms of increased productivity and decreased social benefits paid to patients who are able to work in France, Germany, Italy, and Spain.Keywords: non-small-cell lung cancer, bevacizumab, chemotherapy, economic model, France, Germany, Italy, Spain

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.

Radiomic features derived from the texture analysis of different imaging modalities e show promise in lesion characterisation, response prediction, and prognostication in lung cancer patients. The present study aimed to identify an images-based radiomic signature capable of predicting disease-free survival (DFS) in non-small cell lung cancer (NSCLC) patients undergoing surgery. A cohort of 295 patients was selected. Clinical parameters (age, sex, histological type, tumour grade, and stage) were recorded for all patients. The endpoint of this study was DFS. Both computed tomography (CT) and fluorodeoxyglucose positron emission tomography (PET) images generated from the PET/CT scanner were analysed. Textural features were calculated using the LifeX package. Statistical analysis was performed using the R platform. The datasets were separated into two cohorts by random selection to perform training and validation of the statistical models. Predictors were fed into a multivariate Cox proportional hazard regression model and the receiver operating characteristic (ROC) curve as well as the corresponding area under the curve (AUC) were computed for each model built. The Cox models that included radiomic features for the CT, the PET, and the PET+CT images resulted in an AUC of 0.75 (95%CI: 0.65-0.85), 0.68 (95%CI: 0.57-0.80), and 0.68 (95%CI: 0.58-0.74), respectively. The addition of clinical predictors to the Cox models resulted in an AUC of 0.61 (95%CI: 0.51-0.69), 0.64 (95%CI: 0.53-0.75), and 0.65 (95%CI: 0.50-0.72) for the CT, the PET, and the PET+CT images, respectively. A radiomic signature, for either CT, PET, or PET/CT images, has been identified and validated for the prediction of disease-free survival in patients with non-small cell lung cancer treated by surgery.

Thyroid metastasis of lung cancer is rarely observed in clinical practice. The primary cancers which metastasize to the thyroid gland are mostly renal cell carcinoma, lung cancer, and breast cancer. Transient destructive thyrotoxicosis is caused by massive metastasis of extrathyroid tumors. We herein present a case report of a patient with small cell carcinoma of lung with metastasis to the thyroid and thyrotoxicosis due to toxic multinodular goiter. A 66-year-old man complained of swelling around the right side of the neck, dyspnea, progressive weight loss, and palpitation starting since 3 months before his admission. The patient was diagnosed with small cell carcinoma of lung with metastasis to the thyroid and thyrotoxicosis due to toxic multinodular goiter. The case report presented here illustrates the challenge of making a definitive and adequate diagnosis, particularly if the patient presents with 2 potential causes of thyrotoxicosis. Thyroid scintigraphy is an important tool for differential diagnosis of thyrotoxicosis.

Immunosenescence and immunecheckpoint inhibitors in non-small cell lung cancer patients: Does age really matter?

Immunotherapy has dramatically changed the therapeutic scenario in non-small cell lung cancer (NSCLC), extending overall survival, with a favorable safety profile. However, there is still a gap of knowledge about the efficacy of immune checkpoint inhibitors (ICIs) in elderly patients. Data from randomized clinical trials testing ICIs are conflicting and often lack adequate statistical power. Although two large meta-analyses suggested an absence of a significant survival benefit in patients older than 75years, expanded access programs and retrospective cohort studies of ICIs in the real-life setting, showed comparable survival outcomes and safety profiles between older and younger patients. In this complex scenario, a further unresolved issue is the potential correlation between older age and immunotherapy primary resistance, a phenomenon probably linked to the continuous and progressive remodeling of immune functions with ageing, known as immunosenescence. Defining the role of ICIs in elderly NSCLC patients and exploring the molecular mechanisms underlying a possible lack of benefit or even accelerated tumor growth during immunotherapy are two major challenges for future research in this field of cancer treatment. In this review, we describe the major hallmarks of immunosenescence and we summarize the existing clinical data of ICIs in elderly NSCLC patients. Copyright © 2017 The Author(s).

Full Text Available Abstract Background Lung cancer is considered a terminal illness with a five-year survival rate of about 16%. Informed decision-making related to the management of a disease requires accurate prognosis of the disease with or without treatment. Despite the significance of disease prognosis in clinical decision-making, systematic assessment of prognosis in patients with lung cancer without treatment has not been performed. We conducted a systematic review and meta-analysis of the natural history of patients with confirmed diagnosis of lung cancer without active treatment, to provide evidence-based recommendations for practitioners on management decisions related to the disease. Specifically, we estimated overall survival when no anticancer therapy is provided. Methods Relevant studies were identified by search of electronic databases and abstract proceedings, review of bibliographies of included articles, and contacting experts in the field. All prospective or retrospective studies assessing prognosis of lung cancer patients without treatment were eligible for inclusion. Data on mortality was extracted from all included studies. Pooled proportion of mortality was calculated as a back-transform of the weighted mean of the transformed proportions using the random-effects model. To perform meta-analysis of median survival, published methods were used to pool the estimates as mean and standard error under the random-effects model. Methodological quality of the studies was examined. Results Seven cohort studies (4,418 patients and 15 randomized controlled trials (1,031 patients were included in the meta-analysis. All studies assessed mortality without treatment in patients with non-small cell lung cancer (NSCLC. The pooled proportion of mortality without treatment in cohort studies was 0.97 (95% CI: 0.96 to 0.99 and 0.96 in randomized controlled trials (95% CI: 0.94 to 0.98 over median study periods of eight and three years, respectively.

Background: Pre-operative assessment of non-small cell lung cancer (NSCLC) is a major application of positron emission tomography (FDG-PET). Despite substantial evidence of diagnostic accuracy, relatively little attention has been paid to its effects on patient outcomes. This paper addresses this by extending an existing decision model to include patient-elicited utilities. Patients and methods: A decision-tree model of the effect of FDG-PET on pre-operative staging was converted to a Markov model. Utilities for futile and appropriate thoracotomy were elicited from 75 patients undergoing staging investigation for NSCLC. The decision model was then used to estimate the expected value of perfect information (EVPI) associated with three sources of uncertainty-the accuracy of PET, the accuracy of CT and the patient related utility of a futile thoracotomy. Results: The model confirmed the apparent cost-effectiveness of FDG-PET and indicated that the EVPI associated with the utility of futile thoracotomy considerably exceeds that associated with measures of accuracy. Conclusion: The study highlights the importance of patient related utilities in assessing the cost-effectiveness of diagnostic technologies. In the specific case of PET for pre-operative staging of NSCLC, future research effort should focus on such elicitation, rather than further refinement of accuracy estimates.

Full Text Available Abstract Background Progress in lung cancer is hampered by the lack of clinically useful diagnostic markers. The goal of this study was to provide a detailed evaluation of lung cancer tumor markers indicative of molecular abnormalities and to assess their diagnostic utility in non-small cell lung cancer (NSCLC patients. Methods Quantitative real-time RT-PCR was used to determine LunX, CK19, CEA, VEGF-C and hnRNP A2/B1 mRNA levels in peripheral blood and pleural fluid from NSCLC patients, compared with those from patients with other epithelial cancer (esophagus cancer and breast cancer, benign lung disease (pneumonia and tuberculo pleurisy and from healthy volunteers. Results In peripheral blood LunX mRNA was detectable in 75.0% (33/44 of patients with NSCLC, but not in patients with other epithelial cancer (0/28, benign lung disease (0/10 or in healthy volunteers (0/15. In contrast, all other genetic markers were detected in patients with either NSCLC, other epithelia cancer or benign lung disease, and in healthy volunteers. The expression level and positive rate of LunX mRNA in peripheral blood correlated with the pathologic stage of NSCLC (P LunX mRNA was detected in 92.9% (13/14 of malignant pleural fluid samples and was the only marker whose expression level was significantly different between malignant and benign pleural fluid (P LunX mRNA in the peripheral blood of NSCLC patients decreased shortly after clinical treatment (P = 0.005. Conclusion Of several commonly used genetic markers, LunX mRNA is the most specific gene marker for lung cancer and has potential diagnostic utility when measured in the peripheral blood and pleural fluid of NSCLC patients.

Twisted tail: spinal epidural lipomatosis responding to chemotherapy in a patient with non-small-cell lung cancer

Nasoodi, A.; McAleese, J.; Grey, A.; Stranex, S.

2008-01-01

Full text: Spinal epidural lipomatosis is a rare condition, described in corticoadrenal hyperactivity. It is most commonly seen in association with steroid administration and occasionally with Cushing's syndrome. This is the first case report of spinal epidural lipomatosis as presenting finding in a patient with non-small-cell lung carcinoma without any evidence of endogenous or exogenous hypercortisolism. The additional interesting feature is the paraneoplastic behaviour of this condition and even more interestingly its resolution following chemo-treatment of the primary cancer. Spinal epidural lipomatosis is a benign condition, which must be considered in the differential diagnosis of spinal cord compression in this category of patients. Its pathophysiology remains to be discovered in future.

In patients with unresectable stage III non-small cell lung cancer, we performed chemotherapy and concurrent thoracic radiotherapy. Thirty-five registered patients were intravenously treated with cisplatin (80mg/m{sup 2}) on day 1 and vindesine (3mg/m{sup 2}) on days 1, 3 and were irradiated from days 1 to 10 with single doses of 2.5 Gy up to a total dosage of 20 Gy. Each course lasted 28 days. Patients received 3 courses, and a total dosage of 60 Gy was delivered. Response to this treatment was evaluable in terms of results in 35 patients. Twenty-two patients showed partial response (response rate 62.9%), 10 had no change, and 3 cases had progressive disease. In 7.5 to 37.8 months observation, three PR patients are alive for more than 24 months without recurrence, but eight PR patients died of local relapse, and the median survival time was 15.7 months. Throughout this treatment course, grade 4 leukopenia was noted in 66% and grade 3 thrombocytopenia was observed in 3%. However all were reversible condition and no treatment-related death was observed. However, two cases died due to complications of pulmonary abscess, which occurred in the area of radiation pulmonary fibrosis about one year later after treatment. Although this concurrent chemo-radiotherapy is a tolerable treatment for non-small cell lung cancer and obtained a good response rate, it did not improve the survival rate. (author).

Purpose: To determine whether time to treatment (TTT) has an effect on overall survival (OS) in patients with unresectable or medically inoperable Stage III non-small cell lung cancer (NSCLC) and whether patient or treatment factors are associated with TTT. Methods and Materials: Included in the study were 237 consecutive patients with Stage III NSCLC treated at University of Michigan Hospital (UM) or the Veterans Affairs Ann Arbor Healthcare System (VA). Patients were treated with either palliative or definitive radiotherapy and radiotherapy alone (n = 106) or either sequential (n = 69) or concurrent chemoradiation (n = 62). The primary endpoint was OS. Results: Median follow-up was 69 months, and median TTT was 57 days. On univariate analysis, the risk of death did not increase significantly with longer TTT (p = 0.093). However, subset analysis showed that there was a higher risk of death with longer TTT in patients who survived ≥ 5 years (p = 0.029). Younger age (p = 0.027), male sex (p = 0.013), lower Karnofsky Performance Score (KPS) (p = 0.002), and treatment at the VA (p = 0.001) were significantly associated with longer TTT. However, on multivariate analysis, only lower KPS remained significantly associated with longer TTT (p = 0.003). Conclusion: Time to treatment is significantly associated with OS in patients with Stage III NSCLC who lived longer than 5 years, although it is not a significant factor in Stage III patients as a whole. Lower KPS is associated with longer TTT.

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.

The treatment results for 93 patients aged 75 years or older (elderly group) with limited non-small cell lung cancer (NSCLC) were retrospectively analyzed and compared with those for 193 patients younger than 75-years old (younger group). The elderly patients were classified into two groups: 64 patients aged 75-79 years (the elderly A) and 29 patients aged 80 years or older (the elderly B). All patients were treated with 10 MV X-rays using 2 Gy daily standard fractionation between 1976 and 1994. The total dose ranged from 60 Gy to 80 Gy. The overall two and five year survival rates were 31% and 12% for the elderly A group, and 28% and 6% for the elderly B group, respectively, compared with 34% and 12% for the younger group. In stage I-II NSCLC patients, the 2-year and 5-year disease-specific survival rates were 61% and 43% for the elderly A group, and 55% and 17% for the elderly B group, respectively, while the corresponding rates for younger group were 56% and 22%, respectively. In patients with stage III disease, however, the survival curves of the elderly B were inferior to those of the younger group and the elderly A group, although the difference was not statistically significant. Only two elderly patients died of late pulmonary insufficiency associated with high-dose irradiation of 80 Gy to the proximal bronchus. No other treatment-related event was observed except for mild acceptable acute complications in the elderly groups. The condition of two patients aged more than 80 years, however, deteriorated in mentality during hospitalization. Definitive radiation therapy is recommended to the elderly aged 75 years or older with limited NSCLC, especially early stage disease, as an acceptable choice or treatment. (K.H.)

Full Text Available Abstract Background There is a continued need to develop more effective cancer immunotherapy strategies. Exosomes, cell-derived lipid vesicles that express high levels of a narrow spectrum of cell proteins represent a novel platform for delivering high levels of antigen in conjunction with costimulatory molecules. We performed this study to test the safety, feasibility and efficacy of autologous dendritic cell (DC-derived exosomes (DEX loaded with the MAGE tumor antigens in patients with non-small cell lung cancer (NSCLC. Methods This Phase I study enrolled HLA A2+ patients with pre-treated Stage IIIb (N = 4 and IV (N = 9 NSCLC with tumor expression of MAGE-A3 or A4. Patients underwent leukapheresis to generate DC from which DEX were produced and loaded with MAGE-A3, -A4, -A10, and MAGE-3DPO4 peptides. Patients received 4 doses of DEX at weekly intervals. Results Thirteen patients were enrolled and 9 completed therapy. Three formulations of DEX were evaluated; all were well tolerated with only grade 1–2 adverse events related to the use of DEX (injection site reactions (N = 8, flu like illness (N = 1, and peripheral arm pain (N = 1. The time from the first dose of DEX until disease progression was 30 to 429+ days. Three patients had disease progression before the first DEX dose. Survival of patients after the first DEX dose was 52–665+ days. DTH reactivity against MAGE peptides was detected in 3/9 patients. Immune responses were detected in patients as follows: MAGE-specific T cell responses in 1/3, increased NK lytic activity in 2/4. Conclusion Production of the DEX vaccine was feasible and DEX therapy was well tolerated in patients with advanced NSCLC. Some patients experienced long term stability of disease and activation of immune effectors

Patients with locally advanced lung cancer and very limited pulmonary function (forced expiratory volume in 1 second [FEV1] ≤ 1 L) have dismal prognosis and undergo palliative treatment or best supportive care. We describe two cases of locally advanced node-positive non-small cell lung cancer (NSCLC) patients with very limited lung function treated with induction chemotherapy and moderate hypofractionated image-guided radiotherapy (Hypo-IGRT). Hypo-IGRT was delivered to a total dose of 45 Gy to the primary tumor and involved lymph nodes. Planning was based on positron emission tomography-computed tomography (PET/ CT) and four-dimensional computed tomography (4D-CT). Internal target volume (ITV) was defined as the overlap of gross tumor volume delineated on 10 phases of 4D-CT. ITV to planning target volume margin was 5 mm in all directions. Both patients showed good clinical and radiological response. No relevant toxicity was documented. Hypo-IGRT is feasible treatment option in locally advanced node-positive NSCLC patients with very limited lung function (FEV1 ≤ 1 L)

To evaluate the treatment results in early stage non-small cell lung cancer patients who have undergone fiducial-less CyberKnife radiosurgery (CKRS). 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. 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. 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

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.

NSCLC (non-small cell lung cancer) comprises about 80% of all lung cancer cases worldwide. Surgery is most effective treatment for patients with early-stage disease. However, 30%–55% of these patients develop recurrence within 5 years. Therefore, markers that can be used to accurately classify early-stage NSCLC patients into different prognostic groups may be helpful in selecting patients who should receive specific therapies. A previously published dataset was used to evaluate gene expression profiles of different NSCLC subtypes. A moderated two-sample t-test was used to identify differentially expressed genes between all tumor samples and cancer-free control tissue, between SCC samples and AC/BC samples and between stage I tumor samples and all other tumor samples. Gene expression microarray measurements were validated using qRT-PCR. Bayesian regression analysis and Kaplan-Meier survival analysis were performed to determine metagenes associated with survival. We identified 599 genes which were down-regulated and 402 genes which were up-regulated in NSCLC compared to the normal lung tissue and 112 genes which were up-regulated and 101 genes which were down-regulated in AC/BC compared to the SCC. Further, for stage Ib patients the metagenes potentially associated with survival were identified. Genes that expressed differently between normal lung tissue and cancer showed enrichment in gene ontology terms which were associated with mitosis and proliferation. Bayesian regression and Kaplan-Meier analysis showed that gene-expression patterns and metagene profiles can be applied to predict the probability of different survival outcomes in NSCLC patients.

Full Text Available Abstract Background There are conflicting and inconsistent results in the literature on the prognostic role of quality of life (QoL in cancer. We investigated whether QoL at admission could predict survival in lung cancer patients. Methods The study population consisted of 1194 non-small cell lung cancer patients treated at our institution between Jan 2001 and Dec 2008. QoL was evaluated using EORTC-QLQ-C30 prior to initiation of treatment. Patient survival was defined as the time interval between the date of first patient visit and the date of death from any cause/date of last contact. Univariate and multivariate Cox regression evaluated the prognostic significance of QoL. Results Mean age at presentation was 58.3 years. There were 605 newly diagnosed and 589 previously treated patients; 601 males and 593 females. Stage of disease at diagnosis was I, 100; II, 63; III, 348; IV, 656; and 27 indeterminate. Upon multivariate analyses, global QoL as well as physical function predicted patient survival in the entire study population. Every 10-point increase in physical function was associated with a 10% increase in survival (95% CI = 6% to 14%, p Conclusions Baseline global QoL and physical function provide useful prognostic information in non-small cell lung cancer patients.

Pre-operative assessment of non-small cell lung cancer (NSCLC) is a major application of positron emission tomography (FDG-PET). Despite substantial evidence of diagnostic accuracy, relatively little attention has been paid to its effects on patient outcomes. This paper addresses this by extending an existing decision model to include patient-elicited utilities. A decision-tree model of the effect of FDG-PET on pre-operative staging was converted to a Markov model. Utilities for futile and appropriate thoracotomy were elicited from 75 patients undergoing staging investigation for NSCLC. The decision model was then used to estimate the expected value of perfect information (EVPI) associated with three sources of uncertainty-the accuracy of PET, the accuracy of CT and the patient related utility of a futile thoracotomy. The model confirmed the apparent cost-effectiveness of FDG-PET and indicated that the EVPI associated with the utility of futile thoracotomy considerably exceeds that associated with measures of accuracy. The study highlights the importance of patient related utilities in assessing the cost-effectiveness of diagnostic technologies. In the specific case of PET for pre-operative staging of NSCLC, future research effort should focus on such elicitation, rather than further refinement of accuracy estimates.

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

Serum carcinoembryonic antigen (CEA) and serum squamous cell carcinoma antigen (SCC Ag) levels have been reported to be useful as prognostic factors, indicators of clinical response, and predictors for recurrence in patients with lung cancer treated by surgery or chemotherapy. We investigated whether pretreatment serum CEA and SCC Ag levels were useful as independent prognostic factors in patients with stage I to III non-small cell lung cancer who were treated with radiation therapy alone. The serum CEA and SCC Ag levels were measured in 158 and 47 patients, respectively, before radiation therapy. Serum CEA and SCC Ag levels were measured by sandwich radioimmunoassay using the CEA-RIA (radioimmunoassay) kit and the SCC-RIA kit. Serum CEA and SCC Ag levels were above reference values in 19% and 30% of the patients, respectively. The 5-year survival rates were significantly better for patients with a negative SCC Ag result than for those with positive SCC Ag levels (p=0.0001), though no significant difference in survival rates was seen by CEA positivity (p=0.25). SCC Ag positivity (p=0.0006) and stage (p=0.04) were the important prognostic factors, as determined by multivariate analyses. Pretreatment serum SCC Ag level may be useful as an independent prognostic factor in patients with stage I to III non-small cell lung cancer who are treated with radiation therapy alone. (author)

We retrospectively analyzed the impact of subpleural lesions of early stage non-small cell lung cancer on the patterns of failure to support selection of postoperative adjuvant therapy. The study included 91 patients who underwent surgery for early stage non-small cell lung cancer at Donga University hospital from Dec 1990 to Sep 1996. Twenty five patients were excluded due to postoperative mortality (four patients, 4.4%) and stage III (21 patients). Of 66 patients, 22 patients were subpleural lesions (15 patients in stage I, and seven patients in stage II). Postoperative adjuvant radiation therapy was given to seven patients with T2N1 disease. The median follow-up duration was 29.5 months (range; 8-84 months). The overall survival rate was 69.5% at 3 years. For all patients who presented with (22 patients) and without (44 patients) subpleural lesions, 3-year overall survival rates were 35.5% and 84.6%, respectively (p=0.0017). For stage I patients who presented with (15 patients) and without (29 patients) subpleural lesions, 3-year overall survival rates were 33.1% and 92.3%, respectively (p=0.001). For stage II patients who presented with (7 patients) and without (15 patients) subpleural lesions, 3-year overall survival rates were 53.3% and 45.7%, respectively (p=0.911). For patients with T2NO disease (34 patients) who presented with (11 patients) and without (23 patients) subpleural lesions, 3-year overall survival rates were 27.3% and 90.3%,respectively (p=0.009).These observations suggest that the subpleural lesion play an important role as a prognostic factor for early stage non-small cell lung cancer. Especially for T2NO disease, patients with subpleural lesions showed significantly lower survival rate than those without that

Tumor microenvironment is composed of tumor cells, fibroblasts, endothelial cells, and infiltrating immune cells. Tumor-associated immune cells may inhibit or promote tumor growth and progression. This study was conducted to determine whether the number and microlocalization of macrophages, mature dendritic cells and cytotoxic T cells in non-small cell lung cancer are associated with patient's survival time. Ninety-nine patients with non-small cell lung cancer (NSCLC) were included in this retrospective study. Paraffin-embedded NSCLC specimens and their clinicopathological data including up to 8-year follow-up information were used. Immunohistochemical staining for CD68 (marker for macrophages), CD83 (marker for mature dendritic cells), and CD8 (marker for cytotoxic T cells) was performed and evaluated in a blinded fashion. The numbers of immune cells in tumor islets and stroma, tumor islets, or tumor stroma were counted under a microscope. Correlation of the cell numbers and patient's survival time was analyzed using the Statistical Package for the Social Sciences (version 13.0). The numbers of macrophages, mature dendritic cells and cytotoxic T cells were significantly more in the tumor stroma than in the tumor islets. The number of macrophages in the tumor islets was positively associated with patient's survival time, whereas the number of macrophages in the tumor stroma was negatively associated with patient's survival time in both univariate and multivariate analyses. The number of mature dendritic cells in the tumor islets and stroma, tumor islets only, or tumor stroma only was positively associated with patient's survival time in a univariate analysis but not in a multivariate analysis. The number of cytotoxic T cells in the tumor islets and stroma was positively associated with patient's survival time in a univariate analysis but not in a multivariate analysis.

Availability of tumor and non-tumor patient-derived models would promote the development of more effective therapeutics for non-small cell lung cancer (NSCLC). Recently, conditionally reprogrammed cells (CRC) methodology demonstrated exceptional potential for the expansion of epithelial cells from patient tissues. However, the possibility to expand patient-derived lung cancer cells using CRC protocols is controversial. Here, we used CRC approach to expand cells from non-tumoral and tumor biopsies of patients with primary or metastatic NSCLC as well as pulmonary metastases of colorectal or breast cancers. CRC cultures were obtained from both tumor and non-malignant tissues with extraordinary high efficiency. Tumor cells were tracked in vitro through tumorigenicity assay, monitoring of tumor-specific genetic alterations and marker expression. Cultures were composed of EpCAM+ lung epithelial cells lacking tumorigenic potential. NSCLC biopsies-derived cultures rapidly lost patient-specific genetic mutations or tumor antigens. Similarly, pulmonary metastases of colon or breast cancer generated CRC cultures of lung epithelial cells. All CRC cultures examined displayed epithelial lung stem cell phenotype and function. In contrast, brain metastatic lung cancer biopsies failed to generate CRC cultures. In conclusion, patient-derived primary and metastatic lung cancer cells were negatively selected under CRC conditions, limiting the expansion to non-malignant lung epithelial stem cells from either tumor or non-tumor tissue sources. Thus, CRC approach cannot be applied for direct therapeutic testing of patient lung tumor cells, as the tumor-derived CRC cultures are composed of (non-tumoral) airway basal cells. © 2018 UICC.

Regorafenib is an oral multitargeted kinase inhibitor with potent antiangiogenic activity. In this phase I trial we evaluated the safety, pharmacokinetics, and efficacy of regorafenib with cisplatin and pemetrexed for patients with advanced nonsquamous non-small-cell lung cancers (nsNSCLCs). Nine patients enrolled before premature termination of the study. Five of 9 (56%) patients had a partial response and the median progression-free survival was 7 months (range, 1.5-15.1 months). Regorafenib had acceptable tolerability and minor pharmacokinetic interactions in combination with standard doses of cisplatin and pemetrexed in patients with advanced nsNSCLCs. The combination of bevacizumab, an antiangiogenesis agent, with cytotoxic chemotherapy improves survival in patients with advanced nonsquamous non-small-cell lung cancers (nsNSCLCs). Regorafenib is an oral multitargeted kinase inhibitor with potent antiangiogenic activity that is approved for patients with advanced colorectal cancer and gastrointestinal stromal tumors. In this phase I trial we evaluated the safety, pharmacokinetics (PK), and efficacy of regorafenib with cisplatin and pemetrexed for patients with advanced nsNSCLCs. Chemotherapy-naive patients with advanced nsNSCLCs were treated with regorafenib 60 mg/d continuously and cisplatin 75 mg/m(2) with pemetrexed 500 mg/m(2) once every 21 days for up to 6 cycles. Thereafter, regorafenib with or without pemetrexed could be continued as maintenance. Nine patients enrolled before premature termination of the study because of slow recruitment and a change in the development strategy of regorafenib by the study sponsor. Five patients experienced at least 1 treatment-related Grade 3 adverse event. No Grade 4 or 5 toxicity occurred. Five of 9 (56%) patients had a partial response and the median progression-free survival was 7 months (range, 1.5-15.1 months). Minor PK interactions between regorafenib and chemotherapy were observed. Regorafenib had acceptable

We examined the outcomes of the first 500 patients referred to a dedicated Rapid Access Lung Cancer Clinic. A total of 206 patients (41.2%) were diagnosed with a thoracic malignancy; 179 had primary lung cancer and 27 had secondary or other thoracic cancers. Pulmonary nodules requiring ongoing surveillance were found in a further 79 patients (15.8%). Of those patients found to have primary lung cancer, 24 (13.4%) had Small Cell and 145 (81%) had Non Small Cell Lung Cancer. In patients with Non small cell tumours, 26 (21.1%) were stage 1, 14 (11.4%) stage II, 37 (30.1%) stage III and 46 (37.4%) stage IV at diagnosis. For the 129 patients (72%) in whom the thoracic MDT recommended active treatment, primary therapy was surgical resection in 44 (24.6%), combined chemoradiation in 31 patients (17.3%), chemotherapy alone in 39 (21.8%) and radiation in 15 (8.4%).

2005-01-01

Purpose: To investigate whether prophylactic cranial irradiation (PCI) has a role in the management of patients with non-small-cell lung cancer (NSCLC) treated with curative intent. Methods and Materials: A search strategy was designed to identify randomized controlled trials (RCTs) comparing PCI with no PCI in NSCLC patients treated with curative intent. The electronic databases MEDLINE, EMBASE, LILACS, and Cancerlit were searched, along with relevant journals, books, and review articles to identify potentially eligible trials. Four RCTs were identified and reviewed. A total of 951 patients were randomized in these RCTs, of whom 833 were evaluable and reported. Forty-two patients with small-cell lung cancer were excluded, leaving 791 patients in total. Because of the small patient numbers and trial heterogeneity, no meta-analysis was attempted. Results: Prophylactic cranial irradiation did significantly reduce the incidence of brain metastases in three trials. No trial reported a survival advantage with PCI over observation. Toxicity data were poorly collected and no quality of life assessments were carried out in any trial. Conclusion: Prophylactic cranial irradiation may reduce the incidence of brain metastases, but there is no evidence of a survival benefit. It was not possible to evaluate whether any radiotherapy regimen is superior, and the effect of PCI on quality of life is not known. There is insufficient evidence to support the use of PCI in clinical practice. Where possible, patients should be offered entry into a clinical trial

Objective: To analyse the treatment effect of non-small cell lung cancer of three dimensional conformal radiotherapy (3D-CRT) and to study the effect of patient survival related factors. Methods: Retrospective analysis was mack for 136 cases of non-small cell lung cancer, all accept 3D-CRT, through the case data collection and long-term follow-up, using the single factor and multiple factor analysis survival time and its influencing factors. Results: The recent curative effects of 136 cases of patients with three dimensional conformal radiotherapy: Complete response (CR) 14.7% (20/136), partial response (PR) 60.3 (82/136), stable disease(SD) 19.9% (27/136), progression disease (PD) 5.1% (7/136), total effective rate is 75% (102/136). One, two, three, five year survival rate is 79.4%, 45.4%, 22.1%, 12.5%. Side effects: Class 1 radiated esophagitis 35 cases, Class 2 radiated esophagitis 16 cases, Class 3 and above radiated esophagitis 0 case. Class I radiated pneumonia 20 cases, Class 2 radiated pneumonia 9 cases, Class 3 radiated pneumonia 0 case. Single factor analysis shows the influence of gender, age, pathology, phase, dose, and first-phase curative effect to the survival time are of a statistical significance, Multiple factor analysis showed KPS score, phase, dose, first-phase curative effect are the survival time independent factors. Conclusion: 3D-CRT for patients with non-small cell lung carcinoma is a safe, effective treatment method, Side effects are relatively low, and the patients survival time is long after radiotherapy.

Chemo-radiation is the standard treatment of unresectable, locally advanced non-small cell lung cancer, with a mean dose of 60-66 Gy, excluding escalation dose schemes. The standard treated volume includes primary tumor, ipsilateral hilar and mediastinal nodes, supraclavicular and contralateral nodes as well, regardless of the node status. This work tries to answer the question of the optimal volume to be treated. Drainage routes analysis is in favor of large volumes, while toxicity analysis favors small volumes. Combined modality treatment may increase the observed toxicity. The optimal volume definition is difficult, and requires available conformal therapy tools. Patients selection is another important issue. A volume definition is then attempted, based on the IASLC (International Association for the Study of Lung Cancer) Annecy workshop experience, highlighting the inter-observers discrepancies, and suggests basic recommendations to harmonize volume definition.

PURPOSE: Esophagitis is common in patients treated with definitive radiotherapy for local-regional advanced non small cell lung cancer (NSCLC). The purpose of this study was to estimate the dose-effect relationship using clinical and dosimetric parameters in patients receiving intensity modulated...... significantly associated with esophagitis. The two models using the relative esophagus volume irradiated above 40Gy (V40, OR=2.18/10% volume) or the length of esophagus irradiated above 40Gy (L40, OR=4.03/5cm) were optimal. The upper part of esophagus was more sensitive and females experienced more toxicity...... than men. CONCLUSION: V40 and L40 were most effective dosimetric predictors of grade ⩾2 esophagitis. The upper part of esophagus was more sensitive....

The safety and effectiveness of pemetrexed(PEM)in patients with non-small cell lung cancer(NSCLC)were reviewed using data from post-marketing surveillance. Among 699 patients registered from June 2009 to May 2010, 683 patients were analyzed(343, first-line therapy: 340, second-line therapy or beyond). Patient backgrounds were as follows: median age=65 years(16.1%B75 years old); 64.7% male; 91.9% performance status 0-1; 83.2% Stage IV; 99.0% non-squamous cell cancer. Also, 86% of the first-line and 20% of the second-line cohort were receiving a concomitant anti-cancer drug(mostly platinum agents). The incidence rate of adverse drug reactions(ADR)was 76.7%, including serious cases(18.0%). The most common ADRs were decreased white blood cell count(26.8%), decreased neutrophil count(25.3%), anemia(19.2%), decreased platelet count(17.0%), and nausea(23.0%). The incidence of interstitial lung disease, which is a concern during chemotherapy, was 2.6%. Peripheral neuropathy and alopecia, events influencing a patient's quality of life, were less than 1%. The estimated median survival time was 23.2 months[95%CI: 19.8 months-not calculable]in the first-line cohort, and 11.8 months[95% CI: 10.5-13.7 months]in the B second-line cohort. The surveillance results showed no apparent difference in total ADRs in this current study compared to the safety profile established in clinical trials previously conducted in Japan and overseas. These results demonstrate the safety and effectiveness of PEM treatment for NSCLC patients in daily clinical settings.

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

The release of DNA into peripheral blood is a common event in cancer patients, occurring as a consequence of necrotic and apoptotic processes typical of tumor cells. However, free circulating DNA (fcDNA) is also present in patients with benign diseases and in healthy individuals. Both quantitative and qualitative aspects of fcDNA have been studied as potential biomarkers in a number of tumor types. In particular, quantitative analysis of fcDNA has been shown to play an important role in the diagnosis of non-small cell lung cancer (NSCLC), because of its ability to discriminate between healthy subjects and individuals with NSCLC. Additionally, fcDNA in cancer patients derives predominantly from tumor tissue and, as such, it can be used for the molecular characterization of the primary tumor. Targeted therapies in NSCLC have, in recent years, produced promising results, highlighting the importance of molecular profiling of the primary cancer lesions. Considering that little or no tumor material is available for at least some of the patients, the possibility of using fcDNA for molecular analysis becomes increasingly important. In the present review we evaluated several quantitative and qualitative aspects of fcDNA that could be instrumental for the differential diagnosis of lung disease. There is ample evidence in the literature to support the possible use of peripheral blood-derived fcDNA in the early diagnosis and molecular characterization of lung cancer. This non-invasive method may also turn out to be valuable in monitoring drug response and in identifying induced mechanisms of drug resistance. Before it can be implemented in routine clinical practice, however, additional efforts are needed to standardize the methodology.

Aim: To prospectively assess the cardiopulmonary morbidity and quality of life in patients with non-small cell lung cancer (NSCLC) treated with postoperative radiotherapy (PORT) in comparison to those not receiving PORT. Materials and methods: From 2003 to 2007, 291 patients entered the study; 171 pN2 patients received 3D-planned PORT (PORT group), 120 pN1 patients (non-PORT group) did not. One month after surgery, all patients completed EORTC QLQ C-30 questionnaire and had pulmonary function tests (PFT); cardiopulmonary symptoms were assessed by modified LENT-SOM scale. Two years later, disease-free patients repeated the same examinations. The differences between baseline values and values recorded at two years in QLQ, LENT-SOM and the PFT of the two groups were compared. Results: In the whole cohort, the rate of non-cancer related deaths was 5.3% and 5.0% in PORT and non-PORT group, respectively. Ninety-five patients (47 - PORT group, 48 - non-PORT group) were included into the final analysis. The differences in the QLQ and cardiopulmonary function (LENT/SOM, PFT) between both groups were insignificant. The forced expiratory volume in one second was on average 12.2% and 1.3% better in the PORT and the non-PORT group, respectively, p = 0.2. Conclusions: Our findings support the hypothesis about insignificant morbidity of 3D-planned PORT.

Natural killer T (NKT) cells are involved in the antitumor response by direct cytotoxicity and indirectly through activation of effector cells. Recent studies have shown a relationship between the number and function of NKT cells and clinical outcomes. NKT cells seem to represent a promising tool for immunotherapy of cancer. The aim of the study was to evaluate the distribution of NKT cells in peripheral blood, lymph nodes and tumor tissue of non-small cell lung cancer (NSCLC) patients, as well as development of the most efficient set of cytokines stimulating differentiation of NKT cells. We evaluated the percentage of iNKT+CD3+ cells in the tissues collected from patients with NSCLC. For the generation of NKT cells, we cultured cells isolated from the blood of 20 healthy donors and from the tissues of 4 NSCLC patients. Cells were stimulated with α-GalCer in combinations with cytokines. We noted significant differences in the percentages of NKT cells in the patients' tissues. The highest percentage of these cells was observed in the tumor tissue and the lowest in the lymph nodes. In vitro, in healthy donors all α-GalCer-cytokine combinations were effective in stimulation of NKT cells' proliferation. NKT cells' proliferation was the most efficiently stimulated by α-GalCer+IL-2+IL-7 and α-GalCer+IL-2+IFN-γ. Our results suggest that in the course of NSCLC, NKT cells migrate to the primary tumor and accumulate therein. All tested combinations of α-GalCer and cytokines were capable of generation of NKT cells in vitro.

Integrin α{sub v}β{sub 3} is the therapeutic target of the anti-angiogenic drug cilengitide. The objective of this study was to compare α{sub v}β{sub 3} levels in non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) patients, by using the positron emission tomography (PET) tracer {sup 68}Ga-labeled dimerized-RGD ({sup 68}Ga-RGD{sub 2}). Thirty-one patients with pathologically confirmed lung cancer were enrolled (21 were NSCLC and 10 were SCLC). PET/CT images were acquired using {sup 68}Ga-RGD{sub 2}.{sup 18}F-FDG PET/CT images were also acquired on the consecutive day as reference. The standard uptake values (SUV) and the tumor/nontarget (T/NT) values were quantitatively compared. Expression of the angiogenesis marker α{sub v}β{sub 3} in NSCLC and SCLC lesions was analyzed by immunohistochemistry. The {sup 18}F-FDG SUVmax and the SUVmean were not significantly different between NSCLC and SCLC patients. The {sup 68}Ga-RGD{sub 2} uptake of SCLC patients was at background levels in both SUV and T/NT measurements and was significantly lower than that of NSCLC patients. The range value of {sup 68}Ga-RGD{sub 2} SUVmean was 4.5 in the NSCLC group and 2.2 in the SCLC group, while the variation coefficient was 36.2% and 39.3% in NSCLC and SCLC primary lesions, respectively. Heterogeneity between primary lesions and putative distant metastases was also observed in some NSCLC cases. Immunostaining showed that α{sub v}β{sub 3} integrin was expressed in the cells and neovasculature of NSCLC lesions, while SCLC samples had negative expression. The uptake of {sup 68}Ga-RGD{sub 2} in SCLC patients is significantly lower than that in NSCLC patients, indicating a lower α{sub v}β{sub 3} target level for cilengitide in SCLC. Apparent intra-tumor heterogeneities of α{sub v}β{sub 3} also exist in both NSCLC and SCLC. Such inter- and intra-heterogeneity of α{sub v}β{sub 3} may potentially improve current applications of α{sub v}β{sub 3}-targeted therapy

Lung cancer remains the most common cause of cancer-related death in the United States. This study evaluated the costs of alternative diagnostic evaluations for patients with suspected non-small cell lung cancer (NSCLC). Researchers used a cost-minimization model to compare various diagnostic approaches in the evaluation of patients with NSCLC. It was less expensive to use an initial endoscopic ultrasound (EUS) with fine needle aspiration (FNA) to detect a mediastinal lymph node metastasis ($18,603 per patient), compared with combined EUS FNA and endobronchial ultrasound (EBUS) with FNA ($18,753). The results were sensitive to the prevalence of malignant mediastinal lymph nodes; EUS FNA remained least costly, if the probability of nodal metastases was <32.9%, as would occur in a patient without abnormal lymph nodes on computed tomography (CT). While EUS FNA combined with EBUS FNA was the most economical approach, if the rate of nodal metastases was higher, as would be the case in patients with abnormal lymph nodes on CT. Both of these strategies were less costly than bronchoscopy or mediastinoscopy. The pre-test probability of nodal metastases can determine the most cost-effective testing strategy for evaluation of a patient with NSCLC. Pre-procedure CT may be helpful in assessing probability of mediastinal nodal metastases.

Purpose: to report the results of a prospective randomized study concerning the role of radiotherapy in the treatment of stage III, unresectable, asymptomatic non-small cell lung cancer. Material and methods: between 1992 and 1996, 240 patients with stage III, unresectable, asymptomatic non-small cell lung cancer were enrolled in this study, and sequentially randomized to one of the three treatment arms: conventional irradiation, hypo-fractionated irradiation and control group. In the conventional irradiation arm (79 patients), a dose of 50 Gy in 25 fractions in five weeks was delivered to the primary tumor and the mediastinum. In the hypo-fractionated irradiation arm (81 patients), there were two courses of irradiation separated by an interval of four weeks. In each series, patients received 20 Gy in five fractions in five days, in the same treatment volume as the conventional irradiation group. in the control group arm, 80 patients initially did not receive radiotherapy and were only observed. Delayed palliative hypo-fractionated irradiation (20-25 Gy in four to five fractions in four to five days) was given to the primary tumor when major symptoms developed. Results: the two-year actuarial survival rates for patients in the conventional irradiation, hypo-fractionated irradiation and control group arms were 18%, 6% and 0%, with a median survival time of 12 months, nine months and six months respectively. The differences between survival rates were statistically significant at the 0.05 level. Conclusion: although irradiation provides good palliation the results are disappointing. The comparison of conventional and hypo-fractionated irradiation shows an advantage for conventional schedules. (author)

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.

First-generation epidermal growth factor receptor (EGFR inhibitors have transformed the therapeutic landscape of EGFR mutant non-small-cell lung carcinoma through the genetic stratification of tumors from patients with this disease. Somatic EGFR mutations in lung adenocarcinoma are now well established as predictive biomarkers of response and resistance to small-molecule EGFR inhibitors. Despite early patient benefit, primary resistance and subsequent tumor progression to first-generation EGFR inhibitors are seen in 10%–30% of patients with EGFR mutant non-small-cell lung carcinoma. Acquired drug resistance is also inevitable, with patients developing disease progression after only 10–13 months of antitumor therapy. This review details strategies pursued in circumventing T790M-mediated drug resistance to EGFR inhibitors, which is the most common mechanism of acquired resistance, and focuses on the clinical development of second-generation EGFR inhibitors, exemplified by afatinib (BIBW2992. We discuss the rationale, mechanism of action, clinical efficacy, and toxicity profile of afatinib, including the LUX-Lung studies. We also discuss the emergence of third-generation irreversible mutant-selective inhibitors of EGFR and envision the future management of EGFR mutant lung adenocarcinoma.

Non-small-cell lung cancer (NSCLC) is the commonest cancer worldwide but survival remains poor with a high risk of relapse, particularly after nonsurgical treatment. Hypoxia is present in a variety of solid tumours, including NSCLC. It is associated with treatment resistance and a poor prognosis, although when recognised may be amenable to different treatment strategies. Thus, noninvasive assessment of intratumoral hypoxia could be used to stratify patients for modification of subsequent treatment to improve tumour control. Molecular imaging approaches targeting hypoxic cells have shown some early success in the clinical setting. This review evaluates the evidence for hypoxia imaging using PET in NSCLC and explores its potential clinical utility. (orig.)

Non-small-cell lung cancer (NSCLC) is the commonest cancer worldwide but survival remains poor with a high risk of relapse, particularly after nonsurgical treatment. Hypoxia is present in a variety of solid tumours, including NSCLC. It is associated with treatment resistance and a poor prognosis, although when recognised may be amenable to different treatment strategies. Thus, noninvasive assessment of intratumoral hypoxia could be used to stratify patients for modification of subsequent treatment to improve tumour control. Molecular imaging approaches targeting hypoxic cells have shown some early success in the clinical setting. This review evaluates the evidence for hypoxia imaging using PET in NSCLC and explores its potential clinical utility. (orig.)

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 Kras{sup G12D}-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 radiosensitivity. 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.

The aim of this study was to investigate the mRNA expression levels of multidrug resistance-associated proteins in chemo-naïve metastatic lung cancer cells and to determine the correlation with response to chemotherapy and overall survival. Metastatic cells were obtained by transbronchial fine needle aspiration biopsy of enlarged mediastinal lymph nodes in 14 patients with small cell lung cancer (SCLC) and 7 patients with non-small cell lung cancer (NSCLC). After cytological confirmation of lung cancer type, total RNA was extracted from biopsy samples and reverse transcribed to cDNA, and real-time PCR for the genes of interest [P-glycoprotein (P-gp), multidrug resistance protein 1 (MRP1), breast cancer resistance protein (BCRP), lung resistance protein (LRP) and topoisomerase IIα (TOPIIα)], was performed. We observed significantly decreased expression of BCRP and significantly increased expression of TOPIIα in metastatic SCLC cells compared to NSCLC. Furthermore, in SCLC high topoisomerase IIα and low BCRP expression levels positively correlated with longer overall survival. Our results showed higher expression levels of BCRP as well as lower levels of topoisomerase IIα in chemo-naïve metastatic cells in NSCLC than in SCLC. These results correlate with previous observations that metastatic SCLC cells at the beginning of chemotherapy are potentially more sensitive to chemotherapeutic agents while in metastatic NSCLC cells resistance is usually inherent. We also showed that altered levels of topoisomerase IIα and BCRP in SCLC are important factors that contribute to resistance to chemotherapeutics that interfere with the enzyme and/or DNA and are highly associated with overall survival.

To evaluate the value of combined detection of serum carcinoembryonic antigen (CEA), cytokeratin 19 fragment (CYFRA21-1), and carbohydrateantigen 125 (CA125) for the clinical diagnosis of non- small cell lung cancer (NSCLC). Serum CEA, CYFRA21-1 and CA125 were assessed in 140 patients with NSCLC, 90 patients with benign lung disease and 90 normal control subjects, and differences of expression were compared in each group, and joint effects of these tumor markers in the diagnosis of NSCLC were analyzed. Serum CEA, CYFRA21-1 and CA125 in patients with NSCLC were significantly higher than those with benign lung disease and normal controls (PCEA, CYFRA21-1 and CA125 were 49.45%, 59.67%, and 44.87% respectively. As expected, combinations of these tumor markers improved their sensitivity for NSCLC. The combined detection of CEA+CYFRA21-1 was the most cost-effective combination which had higher sensitivity and specificity in NSCLC. Elevation of serum CEA and CYFRA21-1 was significantly associated with pathological types (PCEA, CYFRA21-1 and CA125 was significantly associated with TNM staging (PCEA, CYFRA21-1 and CA125 is of diagnostic value in the diagnosis of lung cancer, and a joint detection of these three tumor markers, could greatly improve the sensitivity of diagnosis on NSCLC. Combined detection of CEA+CYFRA21-1 proved to be the most economic and practical strategy in diagnosis of NSCLC, which can be used to screen the high-risk group.

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.

Lung cancer is the leading cause of cancer deaths all over the world. As most patients present with advanced disease, major efforts have been made in the treatment of such disease with systemic chemotherapy. Several new agents and new combinations of chemotherapy have been developed recently. This article reviews the randomized clinical trials investigating chemotherapy for advanced non-small cell lung cancer (NSCLC) in relapse or progressive disease while being treated and in elderly patients. Therapies that incorporate new biological agents to target specific defects in lung cancer are also discussed. Several clinical trials have demonstrated improvement in overall survival as well as quality of life with presently available chemotherapy treatment of advanced NSCLC. Better options are available for the elderly as well as those having relapse after first line chemotherapy. Despite all this progress the 5-year survival rate still remains at a dismal 14%. New therapies with good results are still desired. (author)

Full Text Available Aim of the study : Recent studies have suggested that k-RAS mutations are related to the response to epidermal growth factor receptor (EGFR tyrosine-kinase inhibitions (TKIs in advanced non-small cell lung cancer (NSCLC treatment. The aim of this meta-analysis was to assess the relationship between smoking history and k-RAS mutations in NSCLC treated with TKIs. Material and methods : We searched MEDLINE and Web of Science up to 15 March 2014. The pooled relative risk (RR was estimated by using fixed effect model or random effect model, according to heterogeneity between studies. We also carried out power analyses. Results : We identified 12 studies with 1193 patients, including 196 patients (16.4% with k-RAS mutations. The pooled k-RAS mutations incidence was 22.8% (174/764 in patients with smoke expose vs. 5.4% (23/429 in those with no smoke exposure. The pooled RR was 2.991 (95% CI: 1.884–4.746; Z = 4.65, p = 0.000. No publication bias was found (Begg’s test: z = 1.09, p = 0.274 and Egger’s test: t = 1.38, p = 0.201. In subgroup analyses, the pooled RR was 3.336 (95% CI: 1.925–5.779; Z = 4.30, p = 0.000 in the Caucasian subgroup, while in the Asian subgroup the pooled RR was 2.093 (95% CI: 0.909–4.822; Z = 1.73, p = 0.083, but the sample size was underpowered (0.465. Conclusions : The current meta-analysis found that smoking was related to increased incidence of k-RAS mutations in non-small cell lung cancer treated with TKIs. This may be further evidence that smoking will lead to a worse prognosis in NSCLC patients treated with TKIs.

Purpose: Local failure is a major obstacle to the cure of locally advanced non small-cell lung cancer. Three-dimensional conformal radiation therapy (3-DCRT) selects optimal treatment parameters to increase dose to tumor and reduce normal tissue dose, potentially representing an enhancement of the therapeutic ratio of radiation therapy for lung cancer. We performed this analysis of 45 non-small cell lung cancer patients treated with 3-DCRT alone, to evaluate the ability of computer derived lung dose volume histograms to predict serious pulmonary toxicity, to assess the feasibility of this approach, and to examine the resulting survival. Methods: There were 28 males (62%) and 17 females (38%). The median age was 65 (range: 38-82). Tumor stage was Stage I/II in 13%, IIIa in 42%, and IIIb in 44%. The histology was squamous in 44%, adenocarcinoma in 36%, and other non-small cell histologies in the others. Only 47% of patients. had combined favorable prognostic factors (i.e. KPS ≤ 80, and ≤5% wt. loss). The median dose of radiation to gross disease was 70.2 Gy (range: 52.2-72 Gy) delivered in fractions of 1.8 Gy, 5 days per week. Results: Seven patients did not complete 3-DCRT due to disease progression outside the port. Follow-up data are mature: the median follow up of the 6 survivors is 43.5 months (35-59). Thoracic progression occurred in 46%. Median survival (all 45 patients.) is 15.7 months and survival is 32% at 2 years and 12% at 59 months. Pulmonary toxicity ≥grade 3 occurred in 9% of patients. Dose volume histograms were available in 31 patients and showed a correlation between risk of pulmonary toxicity and indices of dose to lung parenchyma. Grade 3 or higher pulmonary toxicity occurred in 38% ((3(8))) of patients with >30% of lung volume receiving ≥25 Gy, versus 4% ((1(23))) of patients with ≤30% lung receiving ≥25 Gy (P = 0.04). Grade 3 or higher pulmonary toxicity occurred in 29% ((4(14))) of patients with a predicted pulmonary normal tissue

Lung cancer is the most common cause of cancer death. About 80% of patients are diagnosed at stage III in the non-small cell lung cancer (NSCLC). It is extremely important to understand the progression of this disease which has low survival times despite the advancing treatment modalities. We aimed to investigate the relationship between early tumor shrinkage (ETS) after initial concurrent chemoradiotherapy (C-CRT) and survival outcome in patients with stage III (NSCLC). A retrospective review of 103 patients with stage III NSCLC who had received C-CRT from January 2006 to October 2011 was performed. Patients were treated with systemic chemotherapy regimen of Cisplatin/Vp-16 and concurrent thoracic radiotherapy at a median dose of 66 Gy (range 60-70 Gy). All patients received a computed tomography (CT) examination before treatment. Also subsequently, chest CT scans were performed with the same imaging parameters at approximately 5 weeks after the initiation of treatment. ETS is here stratified by a decrease in tumor size ≥30% and cancer-related death (P < .05) in stage IIINSCLC. ETS may be served as a useful prognostic factor to predict the outcome of stage III NSCLC patients treated with CCRT.

Local and regional recurrence of non-small cell lung cancer is reported to occur in 13-20% of treatment failures after resection. Reported post-recurrent median survival following radiotherapy ranges from 9 to 14 months. This study examines survival following radiotherapy alone for patients with loco-regionally recurring non-small cell lung cancer after initial surgery. Fifty-five patients, receiving radiotherapy at Westmead Hospital between 1979 and 1997, were eligible for study. Data were collected retrospectively by reviewing patient records. The end-point was overall survival. Symptom control was also recorded. Prognostic factors for analysis included age, sex, original presenting stage, disease-free interval (DFI), performance status, site of recurrence, treatment intent and dose. The median overall survival was 11.5 months (95% confidence interval: 8.1-13.0). Survival following treatment with radical intent was 26 months compared to 10.5 months for patients treated with palliative intent (P = 0.025). There was no significant difference in survival for short (<2 years) or long DFI, performance status, radiation dose, age, sex, site of recurrence or stage. Most patients (55%) had partial or complete resolution of symptoms. Radiotherapy results in overall post-recurrence median survival of nearly 1 year, consistent with previous published data. Radical treatment intent predicts better prognosis as a result of patient selection and higher dose.

For palliative care of spinal bone metastases, stability assessment is of crucial importance. Pathological fractures, instability-related patient immobility and the extent of bone metastasis have been reported to affect patient outcome and these parameters have therefore been used for treatment stratification. We report on stability-dependent fracture and survival rates in over 300 non-small cell lung cancer (NSCLC) patients. Data from 303 patients with 868 osteolytic metastases treated with radiotherapy (RT) between 2000 and 2012 were evaluated retrospectively. In NSCLC patients with bone metastases only, the retrospective 6- and 12-month overall survival (OS) rates were 76.7 and 47.2%, respectively. In patients with additional non-bone distant metastases, these values were 60.0 and 34.0%, respectively. Survival rates were significantly lower in patients with multiple bone metastases and in those suffering pathological fractures (p=0.017). No significant impact of histological type, location of spinal lesions or treatment regime was detected. Furthermore, stability assessment revealed no influence of vertebral column stability on patient outcome (p=0.739). Our analysis demonstrated a correlation between the pathological fractures of bone lesions, the number of bone metastases, additional distant metastases and survival. The results offer a rationale for future prospective investigations. (orig.)

Bcl-2 promotes cell survival by inhibiting adapters needed for the activation and cleavage of caspases thus blocking the proteolytic cascade that ultimately dismantles the cell. Bcl-2 has been investigated as a prognostic factor in non small cell lung cancer (NSCLC) patients with conflicting results. Here, we quantitatively assessed Bcl-2 expression in two large and independent cohorts to investigate the impact of Bcl-2 on survival. AQUA ® , a fluorescent-based method for analysis of in situ protein expression, was used to measure Bcl-2 protein levels and classify tumors by Bcl-2 expression in a cohort of 180 NSCLC patients. An independent cohort of 354 NSCLC patients was used to validate Bcl-2 classification and evaluate outcome. Fifty % and 52% of the cases were classified as high expressers in training and validation cohorts respectively. Squamous cell carcinomas were more likely to be high expressers compared to adenocarcinomas (63% vs. 45%, p = 0.002); Bcl-2 was not associated with other clinical or pathological characteristics. Survival analysis showed that patients with high BCL-2 expression had a longer median survival compared to low expressers (22 vs. 17.5 months, log rank p = 0.014) especially in the subset of non-squamous tumors (25 vs. 13.8 months, log rank p = 0.04). Multivariate analysis revealed an independent lower risk for all patients with Bcl-2 expressing tumors (HR = 0.53, 95% CI 0.37-0.75, p = 0.0003) and for patients with non-squamous tumors (HR = 0.5, 95% CI 0.31-0.81, p = 0.005). Bcl-2 expression defines a subgroup of patients with a favorable outcome and may be useful for prognostic stratification of NSCLC patients

Background: Target therapy with a new class of epidermal growth factor receptor (EGFR) inhibitors shows improved clinical response in EGFR gene-mutated lung cancers. Purpose: To evaluate the use of computed tomography (CT)-guided core-needle biopsy specimens for the assessment of EGFR gene mutation in non-small-cell lung cancer (NSCLC). Material and Methods: Seventeen (nine males, eight females) patients with advanced NSCLC were enrolled in this study. All patients underwent CT-guided core-needle biopsy of the lung tumor prior to treatment with the EGFR inhibitor gefitinib. There were no life-threatening complications of biopsy. The specimens were sent fresh-frozen for EGFR mutation analysis and histopathological study. Results: There were 12 (70.6%) EGFR gene mutants and five (29.4%) nonmutants. The objective response rate to gefitinib therapy was 73.3% (11 of 15 patients), with 91.7% (11 of 12 mutants) for the mutant group and 0% for the nonmutant group. Conclusion: CT-guided core-needle biopsy of advanced NSCLC enables the acquisition of sufficient tissue for EGFR gene mutation analysis

The objective of this study was to prove the principle of CT-guided gene therapy by intratumoral injection of a tumor suppressor gene as an alternative treatment approach of incurable non-small-cell lung cancer. In a prospective clinical phase I trial six patients with non-small-cell lung cancer and a mutation of the tumor suppressor gene p53 were treated by CT-guided intratumoral gene therapy. Ten milliliters of a vector solution (replication-defective adenovirus with complete wild-type p53 cDNA) were injected under CT guidance. In four cases the vector solution was completely applied to the tumor center, whereas in two cases 2 ml aliquots were injected into different tumor areas. For the procedure the scan room had been approved as a biosafety cabinet. Gene transfer was assessed by reverse transcription and polymerase chain reaction in biopsy specimens obtained under CT guidance 24-48 h after therapy. Potential therapeutic efficacy was evaluated on day 28 after treatment using spiral CT. The CT-guided gene therapy was easily performed in all six patients without intervention-related complications. Besides flu-like symptoms, no significant adverse effects of gene therapy were noted. Three of the four patients with central injection exhibited gene transfer in the posttreatment biopsy. Gene transfer could not be proven in the two patients with multiple 2 ml injections. After 28 days, four of the six patients showed stable disease at the treated tumor site, whereas other tumor manifestations progressed. Computed tomography-guided injections are an adequate and easy-to-perform procedure for intratumoral gene therapy. (orig.)

Full Text Available In Taiwan, cancer is the top cause of death, and the mortality rate of lung cancer is the highest of all cancers. Some studies have demonstrated that multidisciplinary team (MDT care can improve survival rates of non-small cell lung cancer (NSCLC patients. However, no study has discussed the effect of MDT care on different stages of NSCLC. The target population for this study consisted of patients with NSCLC newly diagnosed in the 2005-2010 Cancer Registry. The data was linked with the 2002-2011 National Health Insurance Research Database and the 2005-2011 Cause of Death Statistics Database. The multivariate Cox proportional hazards model was used to explore whether the involvement of MDT care had an effect on survival. This study applied the propensity score as a control variable to reduce selection bias between patients with and without involvement of MDT care. The adjusted hazard ratio (HR of death of MDT participants with stage III & IV NSCLC was significantly lower than that of MDT non-participants (adjusted HR = 0.87, 95% confidence interval = 0.84-0.90. This study revealed that MDT care are significantly associated with higher survival rate of patients with stage III and IV NSCLC, and thus MDT care should be used in the treatment of these patients.

Background and purpose: Combined chemoradiotherapy (CRT) is considered the standard care for unresectable stage III non-small cell lung cancer (NSCLC). There have been limited data comparing outcomes of carboplatin vs. cisplatin-based CRT, particularly in elderly. Material and methods: From the Surveillance, Epidemiology and End Results-Medicare registry, we identified 1878 patients >65 years of age with unresected stage III NSCLC that received concurrent CRT between 2002 and 2009. We fitted a propensity score model predicting use of cisplatin-based therapy and compared adjusted overall and lung-cancer specific survival of carboplatin- vs. cisplatin-treated patients. Rates of severe toxicity requiring hospital admission were compared in propensity score adjusted analyses. Results: Overall 1552 (83%) received carboplatin (77% in combination with paclitaxel) and 17% cisplatin (67% in combination with etoposide). Adjusted cox models showed similar overall (hazard ratio [HR]: 0.98; 95% confidence interval [CI]: 0.86–1.12) and lung cancer-specific (HR: 0.99; 95% CI: 0.84–1.17) survival among patients treated with carboplatin vs. cisplatin. Adjusted rates of neutropenia (odds ratio [OR]: 0.35; 95% CI: 0.21–0.61), anemia (OR: 0.67; 95% CI: 0.51–0.89), and thrombocytopenia (OR: 0.51; 95% CI: 0.31–0.85) were lower among carboplatin-treated patients; other toxicities were not different between groups. Conclusion: Carboplatin-based CRT is associated with similar long-term survival but lower rates of toxicity. These findings suggest carboplatin may be the most appropriate chemotherapeutic agent for elderly stage III patients

Full Text Available Background and objective The activation of coagulation and fibrinolysis is frequently encountered among cancer patients. Such tumors are associated with high risk of invasion, metastases, and negative final outcomes. Non-small cell lung cancer (NSCLC accounts for approximately 80% to 85% of all lung malignancies. This study aims to investigate the prognostic value of blood coagulation tests for NSCLC and provide a reference to patients on the prevention and treatment of thrombophilia. Methods Data were collected from 604 cases of hospitalized patients with histologically confirmed NSCLC from January 2009 to December 2012 at the Fourth Hospital of Hebei Medical University. Data included the related indexes of coagulation function in patients before treatment [(i.e., prothrombin time (PT, prothrombin time activity (PTA, international normalized ratio (INR, activated partial thromboplastin time (APTT, fibrinogen (Fib, D-dimer, and platelet count], as well as sex, age, pathological type, TNM stage, and lymph node status. Fifty control subjects without cancer were included in the analysis. Statistical analysis was conducted by using SPSS 13.0 software. Results The plasma level of all coagulation tests including D-dimer, Fib, PT, APTT, INR, and platelet counts revealed statistically significant differences between the patient and control group (P<0.001 for all variables; P=0.001,5 and P=0.004,5 for Fib and platelet counts, respectively. The squamous subtype exhibited high plasma Fib levels (P<0.001 compared with adenocarcinoma cell lung cancer patients. Fib and PLT levels increased (P<0.001 and P=0.014, respectively, and aPTT decreased (P<0.001 in patients at stages III and IV compared with those in patients at stages I and II. aPTT decreased significantly (P<0.001, and Fib and D-dimer levels increased (P<0.001 and P=0.048, respectively in N1-3 patients with NSCLC compared with those of N0 patients. Prolonged PT and INR, high plasma Fib levels, and

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

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 area (%CSAsmall-diameter vessels, with a significant decrease in %CSAsmall pulmonary vascular damage. Use of bevacizumab does not enhance the reduction in area of pulmonary vessels.

Primary lung cancer is the leading cause of cancer death in men in the world. Although the introduction of new drugs, new therapeutic strategies and despite therapeutic advances, the prognosis is relatively improved during the last years. To evaluate the prognosis of patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC) and to identify prognostic factors at these stages. A retrospective study, including 140 cases of locally advanced or metastatic NSCLC diagnosed in our department between 2003 and 2013. The average age was 61±10 years (35 to 90 years). Sex ratio was 18. The delays management were 80±25 days for presentation, 45±20 days for the diagnostic, while the treatment delay was 8±2.33 days. The cancer was at stage IIIA in 14%, IIIB in 27% and IV in 59%. Six months and one-year survival was between 50 and 74% and between 9 and 25%, respectively. Better survival was observed in patients with NSCLC on stage III, having better performance status, having comorbid conditions, with prolonged delays management, a short therapeutic delay and patients who received specific antitumor treatment. The prognostic factors in locally advanced and metastatic NSCLC in our patients were: stage of cancer, performance status, comorbid conditions, delay of management and specific antitumoral treatment. These factors should be considered in the management of patients with advanced NSCLC. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

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

The purpose of this trial was to evaluate the feasibility and efficacy of alternating platinum-based doublet chemotherapy with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in patients with EGFR-mutant non-small cell lung cancer (NSCLC). Chemotherapy-naive patients with advanced NSCLC harboring an EGFR mutation were enrolled. All patients underwent induction chemotherapy by sequentially alternating pemetrexed/cisplatin/bevacizumab and EGFR-TKIs followed by maintenance therapy with pemetrexed/bevacizumab and EGFR-TKIs. The primary outcome was the completion rate of the induction therapy. Eighteen eligible patients were enrolled between May 2011 and March 2016. The completion rate of induction therapy was 72.2% (13/18). Unfortunately, one patient developed grade 4 acute renal injury, but no other serious complications concerning this protocol were observed. Furthermore, diarrhea, rashes, and hematological adverse effects were mild. The completion rate of induction therapy was promising. Alternating chemotherapy and EGFR-TKIs should be further investigated regarding feasibility and efficacy. Copyright© 2018, International Institute of Anticancer Research (Dr. George J.

Genexol-PM is a Cremorphor EL (CrEL)-free polymeric micelle formulation of paclitaxel that allows higher-dose administration with less hypersensitivity. This study was designed to evaluate the efficacy and safety of Genexol-PM and gemcitabine combination in advanced non-small cell lung cancer patients as a first-line treatment. This is a prospective, single-arm, single-center phase II study. Patients with advanced NSCLC received Genexol-PM at 230 mg/m(2) on day 1 and gemcitabine 1,000 mg/m(2) on day 1 and day 8 of a 3-week cycle. Six cycles of chemotherapy were planned unless there was disease progression. The primary endpoint was overall response rate. Forty-three patients received the study drugs with a median of 4 cycles per patient (range 1-6). The overall response rate was 46.5%. The median progression-free survival was 4.0 months (95% CI 2.0-6.0 months), and median overall survival was 14.8 months (95% CI 9.1-20.5 months). The most common toxicities were anemia (n = 29, 67%), asthenia (n = 17, 40%), myalgia (n = 16, 37%), peripheral neuropathy (n = 15, 35 %), and diarrhea (n = 12, 30%). The most common grade 3/4 adverse events were neutropenia (n = 7, 16%) and pneumonia (n = 5, 12%). Two patients died of pneumonia and dyspnea. CrEL-free paclitaxel in combination with gemcitabine demonstrated favorable antitumor activity with little emetogenicities in non-small cell lung cancer patients. However, frequent grade 3/4 toxicities were observed, and safety should be evaluated thoroughly in future studies.

Many patients are not suitable for treatment with epidermal growth factor receptor tyrosine kinase inhibitors (eg, gefitinib, erlotinib, and afatinib or with anaplastic lymphoma kinase inhibitors (eg, crizotinib and ceritinib. As a result, anti-PD-1/PD-L1 and CTLA-4 inhibitors may play a novel role in the improvement of outcomes in a metastatic setting. The regulation of immune surveillance, immunoediting, and immunoescape mechanisms may play an interesting role in this regard either alone or in combination with current drugs. Here, we discuss advances in immunotherapy for the treatment of metastatic non-small-cell lung cancer as well as future perspectives within this framework.

Non small-cell lung cancer and treatment options after tyrosine kinase inhibitors failure in the first line

International Nuclear Information System (INIS)

Chowaniecova, G.

2014-01-01

Introduction: Advanced non-small cell lung cancer with present epidermal growth factor receptor (EGFR) sensitising mutation is standardly treated with tyrosine kinase inhibitors (TKI). During treatment a resistance to TKI develops, disease progresses. We differ primary and secondary resistance. The most effective treatment after TKI failure is not definitively proven. Standard chemotherapy is usually introduced, eventually it is possible to use other TKI in the next lines. Case: The author presents a case of 60-year old patient with lung adenocarcinoma with EGFR sensitising mutation, where primary resistance to TKI was observed. Chemotherapy after progression was introduced. Planned therapy with afatnib was not carried out due to deterioration of patient´s condition. Conclusion: Presented case of EGFR mutation-positive patient represents an example of not very frequent primary resistance to TKI. Mechanisms of primary resistance are not well understood. Treatment after first line TKI failure in non-small cell lung cancer with EGFR mutation represents a challenge for medical research. (author)

Patients with advanced stage non-small cell lung cancer (NSCLC) or small cell lung cancer (SCLC) often experience multidimensional impairments, affecting quality of life during their course of disease. In lung cancer patients with operable disease, several studies have shown that exercise has a positive impact on quality of life and physical functioning. There is limited evidence regarding efficacy for advanced lung cancer patients undergoing palliative treatment. Therefore, the POSITIVE study aims to evaluate the benefit of a 24-week exercise intervention during palliative treatment in a randomized controlled setting. The POSITIVE study is a randomized, controlled trial investigating the effects of a 24-week exercise intervention during palliative treatment on quality of life, physical performance and immune function in advanced, non-operable lung cancer patients. 250 patients will be recruited in the Clinic for Thoracic Diseases in Heidelberg, enrolment begun in November 2013. Main inclusion criterion is histologically confirmed NSCLC (stage IIIa, IIIb, IV) or SCLC (Limited Disease-SCLC, Extensive Disease-SCLC) not amenable to surgery. Patients are randomized into two groups. Both groups receive weekly care management phone calls (CMPCs) with the goal to assess symptoms and side effects. Additionally, one group receives a combined resistance and endurance training (3x/week). Primary endpoints are quality of life assessed by the Functional Assessment of Cancer Therapy for patients with lung cancer (FACT-L, subcategory Physical Well-Being) and General Fatigue measured by the Multidimensional Fatigue Inventory (MFI-20). Secondary endpoints are physical performance (maximal voluntary isometric contraction, 6-min walk distance), psychosocial (depression and anxiety) and immunological parameters and overall survival. The aim of the POSITIVE trial is the evaluation of effects of a 24-week structured and guided exercise intervention during palliative treatment stages

Treatment paradigms for patients with metastatic non small cell lung cancer (NSCLC, squamous lung cancer: first, second and third-line

Full Text Available Historically, the treatment algorithm applied to non small cell lung cancer (NSCLC was the same for all histologic subtypes. However, recent advances in our understanding of the molecular profiles of squamous and non-squamous NSCLC have changed this perspective. Histologic subtype and the presence of specific molecular abnormalities have predictive value for response to and toxicity from therapy, as well as overall survival. For patients with squamous NSCLC, a platinum agent plus gemcitabine, or paclitaxel is recommended as first-line therapy. The role of EGFR monoclonal antibodies is uncertain. Maintenance therapy is not widely recommended, although data exist for the use of erlotinib. The standard recommendation for second-line therapy is docetaxel and erlotinib should be considered as second or third-line therapy. There is ongoing research identifying molecular targets in squamous NSCLC and many agents are in early phase clinical trials. Immunotherapeutic approaches targeting programmed death 1 receptor (PD-1 and its ligand (PD-L1 appear promising.

Platelet to lymphocyte ratio (PLR) was recently reported as a useful index in predicting the prognosis of lung cancer. However, the prognostic role of PLR in lung cancer remains controversial. The aim of this study was to evaluate the association between PLR and clinical outcome of lung cancer patients through a meta-analysis. Relevant literatures were retrieved from PubMed, Ovid, the Cochrane Library and Web of Science databases. Meta-analysis was performed using hazard ratio (HR) and 95% confidence intervals (CIs) as effect measures. A total of 5,314 patients from 13 studies were finally enrolled in the meta-analysis. The summary results showed that elevated PLR predicted poorer overall survival (OS) (HR: 1.526, 95%CI: 1.268-1.836, p analysis revealed that increased PLR was also associated with poor OS in NSCLC treated by surgical resection (HR: 1.884, 95%CI: 1.308-2.714, P 160 (HR: 1.842, 95%CI: 1.523-2.228, P  0.05) in patients with small cell lung cancer (SCLC).This meta-analysis result suggested that elevated PLR might be a predicative factor of poor prognosis for NSCLC patients. © 2016 UICC.

Microarray slides from a set of 178 NSCLC patients were used for the detection of TS, OPRT, and TP expression by immunohistochemistry. The correlation between clinicopathologic factors and protein expression of three proteins was analyzed. Ninety seven carcinomas (57.4% were TS-positive, 90 carcinomas (53.9% were OPRT-positive, and 102 carcinomas (69.4% were TP-positive. Compared with the TS-positive patients, the overall survival (OS was significantly lower in the TS-negative patients (hazard ratio [HR] =1.766, 95% confidence interval [CI] =1.212–2.573, P=0.003. Significant differences between TS-positive and TS-negative patients was also observed in the following stratified analyses: 1 adenocarcinoma subgroup (HR =2.079, 95% CI =1.235–3.500, P=0.006; 2 less than 60-year-old subgroup (HR =1.890, 95% CI =1.061–3.366, P=0.031; 3 stage II/III subgroup (HR =1.594, 95% CI =1.036–2.453, P=0.034; and 4 surgery plus adjuvant therapy subgroup (HR =1.976, 95% CI =1.226–3.185, P=0.005. However, the OS was not significantly correlated with OPRT or TP protein expression. This study demonstrates that the TS level in tumor tissues may be a useful marker

Aim To determine the pharmacogenetics of platinum-based chemotherapy in Non Small Cell Lung Cancer (NSCLC) patients. Methods Publications were selected from PubMed, Cochrane Library and ISI Web of Knowledge. A meta-analysis was conducted to determine the association between genetic polymorphisms and platinum-based chemotherapy by checking odds ratio (OR) and 95% confidence interval (CI). Results Data were extracted from 24 publications, which included 11 polymorphisms in 8 genes for meta-analysis. MDR1 C3435T (OR = 1.97, 95% CI: 1.11–3.50, P = 0.02), G2677A/T (OR = 2.61, 95% CI: 1.44–4.74, P = 0.002) and GSTP1 A313G (OR = 0.32, 95% CI: 0.17–0.58, P = 0.0002) were significantly correlated with platinum-based chemotherapy in Asian NSCLC patients. Conclusion Attention should be paid to MDR1 C3435T, G2677A/T and GSTP1 A313G for personalized chemotherapy treatment for NSCLC patients in Asian population in the future. PMID:22761669

The tumor-to-brain communication has been emphasized by recent converging evidences. This study aimed to compare the difference of brain glucose metabolism between patients with non-small cell lung cancer (NSCLC) and control subjects. NSCLC patients prior to oncotherapy and control subjects without malignancy confirmed by 6 months follow-up were collected and underwent the resting state 18F-fluoro-D-glucose (FDG) PET/CT. Normalized FDG metabolism was calculated by a signal intensity ratio of each brain region to whole brain. Brain glucose metabolism was compared between NSCLC patients and control group using two samples t-test and multivariate test by statistical parametric maps (SPM) software. Compared with the control subjects (n = 76), both brain glucose hyper- and hypometabolism regions with significant statistical differences (Pbrain signal transduction pathways, and the hypometabolism regions (the left superior parietal lobule, bilateral inferior parietal lobule and left fusiform gyrus) lied in dorsal attention network and visuospatial function areas. The changes of brain glucose metabolism exist in NSCLC patients prior to oncotherapy, which might be attributed to lung-cancer related visceral sympathetic activation and decrease of dorsal attention network function.

Lung cancer is the leading cause of cancer death in the United States and many other parts of the world. Non-small cell lung cancer (NSCLC) comprises 85-90% of lung cancers. Historically, the expected survival of patients with advanced disease has been estimated in months. In recent years, however, lung cancer has come to be seen as a treatable disease with multiple therapeutic options. Enormous advances in the understanding of its pathways and mechanisms have enabled personalized therapy in NSCLC. The evolving approach to therapy focuses on genomic profiling of the tumors to find molecular targets and develop specific agents for individualized therapy. In addition, maintenance therapy has emerged as a valid approach, and the choice of chemotherapy now varies by histology. Most recently, immunotherapy with checkpoint inhibitors has shown promising results, with impressive durations of response and a tolerable toxicity profile. Together, these discoveries have improved overall survival substantially in patient populations that have access to these advancements. We review the clinical data surrounding these impressive improvements.

Full Text Available Background and objective Screen differentially expressed proteins in patients with non-small cell lung cancer (NSCLC, and aim to identify biomarkers for early screening, monitoring prognosis and evaluating therapy of NSCLC. Methods Urinary samples were collected from 40 newly diagnosed NSCLC patients, 8 patients with lung benign disorders and 22 healthy people. 0.9% sodium dodecylsulfate- polyacrylamide gel electrophoresis (1D SDS-PAGE and MS-Thermo-Orbitrap-Velos were applied to separate, extract and identify proteins in urinary samples from non-neoplastic groups and NSCLC patients, in order to find out differentially expressed proteins in patients with NSCLC. Then, sensitivity and specificity of candidate proteins were tested by certain experiments. Finally, biomarkers related to NSCLC could be determined. Results The differences of urinary proteins between non-neoplastic groups and NSCLC patients mainly focused on 90 kDa, 60 kDa and 20 kDa-30 kDa stripes. Four differently expressed proteins were found in urinary proteins in NSCLC group, including LRG1, CA1 (up-regulating proteins and VPS4B, YWHAZ (down-regulating proteins. The sensitivity of these four proteins for biomarker of NSCLC was relatively low when they were used to screen or diagnose independently. The sensitivity and specificity of LRG1 was 83.0% (25/30 and 90.0% (18/20, respectively; 60.0% (18/30 and 90.0% (18/20 for CA1; 73.3% (22/30 and 90.0% (18/20 for VPS4B; 60.0% (18/30 and 95.0% (19/20 for YWHAZ. However, the sensitivity and specificity would increase to 96.7% (29/30 and 85% (17/20 after the four biomarkers were combined. Conclusion LRG1 and CA1 are abundant in urine in patients with NSCLC, while VPS4B and YWHAZ are low-abundance proteins. They could be regarded as biomarkers for early screening, monitoring prognosis and evaluating therapy of patients with NSCLC because of differential expression. The sensitivity of the four biomarkers of NSCLC is relatively low when they

Full Text Available The use of sublobar resections as definitive management in stage I non-small cell lung carcinoma is a controversial topic in the medical community. We intend to report the latest developments and trends in relative indications for each of the above-mentioned surgical approaches for the treatment of stage I non-small cell lung carcinoma as well as the results of studies regarding local recurrence, disease-free survival and five-year survival rates. We reviewed 45 prospective and retrospective studies conducted over the last 25 years listed in the Pubmed and Scopus electronic databases. Trials were identified through bibliographies and a manual search in journals. Authors, citations, objectives and results were extracted. No meta-analysis was performed. Validation of results was discussed. Segmentectomies are superior to wedge resections in terms of local recurrences and cancer-related mortality rates. Sublobar resections are superior to lobectomy in preserving the pulmonary parenchyma. High-risk patients should undergo segmentectomy, whereas lobectomies are superior to segmentectomies only for tumors >2 cm (T2bN0M0 in terms of disease-free and overall 5-year survival. In most studies no significant differences were found in tumors <2 cm. Disease-free surgical margins are crucial to prevent local recurrences. Systematic lymphadenectomy is mandatory regardless of the type of resection used. In sublobar resections with less thorough nodal dissections, adjuvant radiotherapy can be used. This approach is preferable in case of prior resection. In pure bronchoalveolar carcinoma, segmentectomy is recommended. Sublobar resections are associated with a shorter hospital stay. The selection of the type of resection in T1aN0M0 tumors should depend on characteristic of the patient and the tumor. Patient age, cardiopulmonary reserve and tumor size are the most important factors to be considered. However further prospective randomized trials are needed to

Structured Abstract Purpose The addition of bevacizumab, an anti-angiogenesis agent, to cytotoxic chemotherapy improves survival in patients with advanced non-squamous non-small cell lung cancers (nsNSCLCs). Regorafenib is an oral multi-targeted kinase inhibitor with potent anti-angiogenic activity that is approved for patients with advanced colorectal cancer and gastrointestinal stromal tumors. This phase I trial evaluated the safety, pharmacokinetics, and efficacy of regorafenib with cisplatin and pemetrexed for patients with advanced nsNSCLCs. Methods Chemotherapy-naïve patients with advanced nsNSCLCs were treated with regorafenib 60mg/day continuously and cisplatin 75mg/m2 plus pemetrexed 500mg/m2 once every three weeks for up to six cycles. Thereafter, regorafenib with or without pemetrexed could be continued as maintenance. Results Nine patients enrolled prior to premature termination of the study due to slow recruitment and a change in the development strategy of regorafenib by the study sponsor, partially due to slow enrollment. Five patients experienced at least one treatment-related Grade 3 adverse event. No grade 4–5 toxicity occurred. 5 of 9 (56%) patients had a partial response and the median progression-free survival was 7 months (range 1.5–15.1). Minor pharmacokinetic (PK) interactions between regorafenib and chemotherapy were observed. Conclusions Regorafenib had acceptable tolerability and minor PK interactions in combination with standard doses of cisplatin and pemetrexed in patients with advanced nsNSCLCs. Encouraging activity was appreciated in chemotherapy-naïve patients with advanced nsNSCLCs. However, the small number of patients treated limits conclusions that can be drawn from these results.

Several clinical trials have proven that icotinib hydrochloride, a novel epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor, exhibits encouraging efficacy and tolerability in patients with advanced non-small-cell lung cancer (NSCLC) who failed previous chemotherapy. This study was performed to assess the efficacy and toxicity of icotinib as first-line therapy for patients with advanced pulmonary adenocarcinoma with EGFR-sensitive mutation. Thirty-five patients with advanced NSCLC with EGFR-sensitive mutation who were sequentially admitted to the First Affiliated Hospital of Xi'an Jiaotong University from March 2012 to March 2014 were enrolled into our retrospective research. All patients were administered icotinib as first-line treatment. The tumor responses were evaluated using Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1). Among the 35 patients, the tumor objective response rate (ORR) and disease control rate were 62.9% (22/35) and 88.6% (31/35), respectively. The median progression-free survival was 11.0 months (95% confidence interval [CI]: 10.2-11.8 months), and median overall survival was 21.0 months (95% CI: 20.1-21.9 months). The most common drug-related toxicities were rashes (eleven patients) and diarrhea (nine patients), but these were generally manageable and reversible. Icotinib monotherapy is effective and tolerable as first-line treatment for patients with advanced lung adenocarcinoma with EGFR-sensitive mutation.

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

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.

Successful Management of Crizotinib-Induced Neutropenia in a Patient with Anaplastic Lymphoma Kinase-Positive Non-Small Cell Lung Cancer: A Case Report

Directory of Open Access Journals (Sweden)

Jun Osugi

2016-01-01

Full Text Available Crizotinib, the first clinically available inhibitor of anaplastic lymphoma kinase (ALK gene rearrangement, is generally well tolerated. In contrast, neutropenia induced by crizotinib is a commonly reported grade 3 or 4 adverse event. In such cases, interruption and dose reduction of crizotinib might be necessary for some patients with severe neutropenia. However, information concerning clinical experience and management of severe neutropenia is currently limited. In this report, the successful management of crizotinib-induced neutropenia by dose reduction of crizotinib in a patient with ALK-positive non-small cell lung cancer is described.

Sarcopenia is the progressive loss of muscle mass and strength, and has a risk of adverse outcomes such as disability, poor quality of life and death. As prognosis depends not only on disease aggressiveness, but also on a patient's physical condition, sarcopenia can predict survival in patients with various cancer types. However, its effects on postoperative prognosis in patients with localized non-small cell lung cancers (NSCLC) have never been reported. We retrospectively investigated 215 male patients with pathological Stage I NSCLC. L3 muscle index is defined as the cross-section area of muscle at the third lumbar vertebra level, normalized for height, and is a clinical measurement of sarcopenia. We then investigated the effect of preoperative sarcopenia on their postoperative prognosis. Our 215 subjects included 30 patients with sarcopenia. Sarcopenia was significantly associated with body mass index, nutritional condition, serum CYFRA 21-1 level and pathological stage, but not with preoperative respiratory function or performance status. Frequency of postoperative complications, length of postoperative hospital stay, thoracic drainage period or causes of death were not correlated with the presence of sarcopenia. The sarcopenia group had a significantly shorter median overall survival (32 months) than the no-sarcopenia group. Sarcopenia might not affect short-term outcomes in patients with early-stage lung cancer. Sarcopenia was a predictor of poor prognosis in male patients with Stage I NSCLC. As sarcopenic patients with NSCLC patients are at risk for significantly worse outcomes, their treatments require careful planning, even for those with Stage I disease. © The Author 2017.

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.

Despite reported discordance between the mutational status of primary lung cancers and their metastases, metastatic sites are rarely biopsied and targeted therapy is guided by genetic biomarkers detected in the primary tumor. This situation is mostly explained by the apparent stability of EGFR-activating mutations. Given the dramatic increase in the range of candidate drugs and high rates of drug resistance, rebiopsy or liquid biopsy may become widespread. The purpose of this study was to test genetic biomarkers used in clinical practice (EGFR, ALK) and candidate biomarkers identified by the French National Cancer Institute (KRAS, BRAF, PIK3CA, HER2) in patients with metastatic non-small-cell lung cancer for whom two tumor samples were available. A retrospective study identified 88 tumor samples collected synchronously or metachronously, from the same or two different sites, in 44 patients. Mutation analysis used SNaPshot (EGFR, KRAS, BRAF missense mutations), pyrosequencing (EGFR and PIK3CA missense mutations), sizing assays (EGFR and HER2 indels) and IHC and/or FISH (ALK rearrangements). About half the patients (52 %) harbored at least one mutation. Five patients had an activating mutation of EGFR in both the primary tumor and the metastasis. The T790M resistance mutation was detected in metastases in 3 patients with acquired resistance to EGFR tyrosine kinase inhibitors. FISH showed discordance in ALK status between a small biopsy sample and the surgical specimen. KRAS mutations were observed in 36 % of samples, six patients (14 %) having discordant genotypes; all discordances concerned sampling from different sites. Two patients (5 %) showed PI3KCA mutations. One metastasis harbored both PI3KCA and KRAS mutations, while the synchronously sampled primary tumor was mutation free. No mutations were detected in BRAF and HER2. This study highlighted noteworthy intra-individual discordance in KRAS mutational status, whereas EGFR status was stable. Intratumoral

This study investigates the ability of pre-treatment factors and response markers extracted from standard cone-beam computed tomography (CBCT) images to predict the lung density changes induced by radiotherapy for non-small cell lung cancer (NSCLC) patients. Density changes in follow-up computed tomography scans were evaluated for 135 NSCLC patients treated with radiotherapy. Early response markers were obtained by analysing changes in lung density in CBCT images acquired during the treatment course. The ability of pre-treatment factors and CBCT markers to predict lung density changes induced by radiotherapy was investigated. Age and CBCT markers extracted at 10th, 20th, and 30th treatment fraction significantly predicted lung density changes in a multivariable analysis, and a set of response models based on these parameters were established. The correlation coefficient for the models was 0.35, 0.35, and 0.39, when based on the markers obtained at the 10th, 20th, and 30th fraction, respectively. The study indicates that younger patients without lung tissue reactions early into their treatment course may have minimal radiation induced lung density increase at follow-up. Further investigations are needed to examine the ability of the models to identify patients with low risk of symptomatic toxicity. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Full Text Available Background and objective Approximately 35%-40% of patients with newly diagnosed non-small cell Lung cancer have locally advanced disease. The average survival time of these patients only have 6-8 months with chemotherapy. The aim of this study is to explore and summarize the probability of detection of micrometastasis in peripheral blood for molecular staging, and for selection of indication of surgical treatment, and beneficiary of neoadjuvant chemotherapy and postoperative adjuvant therapy in locally advanced lung cancer; to summarize the long-time survival result of personalized surgical treatment of 516 patients with locally advanced non-small cell lung cancer based on molecular staging methods. Methods CK19 mRNA expression of peripheral blood samples was detected in 516 lung cancer patients by RT-PCR before operation for molecular diagnosis of micrometastasis, personalized molecular staging, and for selection of indication of surgical treatment and the beneficiary of neoadjuvant chemotherapy and postoperative adjuvant therapy in patients with locally advanced nonsmall cell lung cancer invaded heart, great vessels or both. The long-term survival result of personalized surgical treatment was retrospectively analyzed in 516 patients with locally advanced non-small cell lung cancer based on molecular staging methods. Results There were 322 patients with squamous cell carcinoma and 194 cases with adenocarcinoma in the series of 516 patients with locally advanced lung cancer involved heart, great vessels or both. There were 112 patients with IIIA disease and 404 cases with IIIB disease according to P-TNM staging. There were 97 patients with M-IIIA disease, 278 cases with M-IIIB disease and 141 cases with III disease according to our personalized molecular staging. Of the 516 patients, bronchoplastic procedures and pulmonary artery reconstruction was carried out in 256 cases; lobectomy combined with resection and reconstruction of partial left

This study explored the fascin-1 protein’s expression in non-small cell lung cancer (NSCLC tissues and its relationship with clinical pathology and prognostic indicators.Methods: Immunohistochemical analysis was used to determine the expression of fascin-1 in NSCLC tissues. We used quantitative real-time polymerase chain reaction and western blot analysis to further verify the results. The fascin-1 expression and statistical method for clinical pathological parameters are examined by χ2. Kaplan–Meier method is used for survival analysis. Cox’s Proportional Hazard Model was used to conduct a combined-effect analysis for each covariate.Results: In 73 of the 128 cases, NSCLC cancer tissues (57.0% were found with high expression of fascin-1, which was significantly higher than the adjacent tissues (35/128, 27.3%. The results suggested that the high expression of fascin-1 was significantly correlated with lymph node metastasis (P=0.022 and TNM stage (P=0.042. The high fascin-1 expression patients survived shorter than those NSCLC patients with low fascin-1 expression (P<0.05. Univariate analysis revealed that lymph node metastasis, TNM stage, and fascin-1 expression status were correlated with the overall survival. Similarly, lymph node metastasis, TNM stage, and fascin-1 expression status were significantly associated with the overall survival in multivariate analyses by using the Cox regression model.Conclusion: The fascin-1 protein may be a useful prognostic indicator and

Proto-oncogene Pokemon is the special transcription inhibitor of ARF,which can regulate cell growth and differentiation by ARF-P53 path.It may be the important monitoring target of tumor because of being upstream region of many tumor suppressor genes and proto-oncogenes.The aim of this study is to explore the clinical significance of Pokemon gene in non-small cell lung cancer(NSCLC). Immunohistochemistry was applied to detect the expression of Pokemon protein in 92 cases of NSCLC and 20 cases of paracancerous lung tissues.Correlation between abnormal expression of Pokemon with pathologic characteristics and prognosis of NSCLC was analyzed. Pokemon was not expressed in paracancerous lung tissues and was found in 66 of 92(71.7%) cases of lung cancer tissues.Expression of Pokemon was closely related to TNM stages(P=0.011).Survival rate of patients with negative Pokemon expression was significantly higher than that of those with positive Pokemon expression(P=0.0015).Pokemon expression was demonstrated as independent prognostic factor of NSCLC. Pokemon is expressed in NSCLC and it may be identified as a new diagnostic marker.High expression of Pokemon may indicate poor prognosis of patients with NSCLC.
