RESUMEN

PURPOSE: Squamous non-small-cell lung cancer (sqNSCLC) is genetically complex with evidence of DNA damage. This phase III study investigated the efficacy and safety of poly (ADP-ribose) polymerase inhibitor veliparib in combination with conventional chemotherapy for advanced sqNSCLC (NCT02106546). PATIENTS AND METHODS: Patients age ≥ 18 years with untreated, advanced sqNSCLC were randomly assigned 1:1 to carboplatin and paclitaxel with veliparib 120 mg twice daily (twice a day) or placebo twice a day for up to six cycles. The primary end point was overall survival (OS) in the veliparib arm versus the control arm in current smokers, based on phase II findings. Archival tumor samples were provided for biomarker analysis using a 52-gene expression histology classifier (LP52). RESULTS: Overall, 970 patients were randomly assigned to carboplatin and paclitaxel plus either veliparib (n = 486) or placebo (n = 484); 57% were current smokers. There was no significant OS benefit with veliparib in current smokers, with median OS 11.9 versus 11.1 months (hazard ratio [HR], 0.905; 95% CI, 0.744 to 1.101; P = .266). In the overall population, OS favored veliparib; median OS was 12.2 versus 11.2 months (HR, 0.853; 95% CI, 0.747 to 0.974), with no difference in progression-free survival (median 5.6 months per arm). In patients with biomarker-evaluable tumor samples (n = 360), OS favored veliparib in the LP52-positive population (median 14.0 v 9.6 months; HR, 0.66; 95% CI, 0.49 to 0.89), but favored placebo in the LP52-negative population (median 11.0 v 14.4 months; HR, 1.33; 95% CI, 0.95 to 1.86). No new safety signals were observed in the experimental arm. CONCLUSION: In current smokers with advanced sqNSCLC, there was no therapeutic benefit of adding veliparib to first-line chemotherapy. The LP52 signature may identify a subgroup of patients likely to derive benefit from veliparib with chemotherapy.

RESUMEN

BACKGROUND/AIM: Sex-related differences have not been thoroughly explored in chronic obstructive pulmonary disease (COPD). We aimed to evaluate possible sex-related differences in COPD Assessment Test (CAT) scores of COPD patients with or without significant anxiety and/or depression. MATERIALS AND METHODS: Stable COPD patients were prospectively enrolled in the study between July 2013 and April 2014. Levels of anxiety, depression, dyspnea, and health-related quality of life parameters were assessed using specific questionnaires, including the CAT and others. Demographic and clinical data were recorded and physiological tests were performed. All the data were compared to determine any sex-related differences. RESULTS: A total of 128 COPD patients (86 men, 42 women, mean age: 60.5 ± 9.3 years) were included. The women were significantly younger and had lower pack-years of cigarette smoking, and higher biomass smoke exposure, but displayed similarly severe COPD as compared to men. Beck anxiety (13.5-11) and Beck depression (15-11) inventory results were significantly higher in women than men (P = 0.04, P = 0.01). No statistically significant difference was found between the sexes in terms of CAT score, Modified Medical Research Council score, or COPD stage parameters (P > 0.05). CONCLUSION: Female patients have higher levels of depression and anxiety scores but present the same CAT scores related to COPD severity as compared to men.

RESUMEN

OBJECTIVES: Active smokers with non-small-cell lung cancer (NSCLC) have increased erlotinib metabolism versus non-smoking patients, which reduces exposure. Therefore, an increased erlotinib dose may be beneficial. The CurrentS study (NCT01183858) assessed efficacy and safety of 300mg erlotinib (E300) as second-line therapy in current smokers with locally advanced or metastatic NSCLC versus the standard 150mg dose (E150). MATERIALS AND METHODS: Patients with stage IIIB/IV NSCLC (current smokers who failed first-line platinum-based chemotherapy) were randomized to receive E150 or E300 until progression/death/unacceptable toxicity. PRIMARY ENDPOINT: progression-free survival (PFS). Secondary endpoints: overall survival (OS), disease control rate and safety. RESULTS: A total of 342 patients were screened; the intent-to-treat population comprised 159 E300 patients and 154 E150 patients. Median PFS was 7.0 versus 6.9 weeks with E300 versus E150, respectively (unstratified hazard ratio [HR]=1.05, 95% confidence interval [CI]: 0.83-1.33; unstratified log-rank P=0.671). Median OS was 6.8 months in both arms (unstratified HR=1.03, 95% CI: 0.80-1.32; unstratified log-rank P=0.846). Overall, 89.2% (E300 arm) and 84.4% (E150 arm) experienced ≥1 adverse event (AE) of any grade (44.3% and 37%, respectively, experienced grade ≥3 AEs); AEs of special interest were reported in 67.7% and 47.4% of patients, respectively. E300 resulted in higher mean plasma concentrations versus E150, however, this did not improve efficacy. CONCLUSIONS: Despite the difference in erlotinib exposure, there was no evidence of an incremental efficacy benefit of a higher erlotinib dose versus the standard dose in this population of highly active smokers.

RESUMEN

BACKGROUND: Low adherence to Global initiative for chronic Obstructive Lung Disease (GOLD) guideline recommendations has been reported worldwide. There has been no study on the adherence to GOLD guidelines for COPD treatment in Turkey. OBJECTIVES: To investigate the rates of adherence to GOLD 2010 guidelines for COPD treatment among pulmonologists. DESIGN: A multi-center, cross-sectional, observational study was carried out in eleven pulmonary outpatient clinics across Turkey. Adherence to GOLD was evaluated through hospital records. Demographic and clinical data were recorded. RESULTS: Study included 719 patients (mean age: 62.9±9.7 years; males 85.4%) of whom 16 was classified as GOLD Stage I, 238 as II, 346 as III, and 119 as IV, and only 59.5% received appropriate treatment. Rates of guideline adherence varied across GOLD stages (I, 6.3%; II, 14.7%; III, 84.4%; and IV, 84%). Causes of inappropriate therapies were overtreatment (Stage I, 100% and Stage II, 91.1%), undertreatment (Stage III, 3.3% and Stage IV, 10.9%) and lack of treatment (Stage II, 3.8%; Stage III, 2.3%; and Stage IV, 5.9%). The most preferred regimen (43.4%) was long-acting ß2-agonist-inhaled corticosteroid-long-acting muscarinic antagonist. Overall, 614 patients (89%) received treatment containing inhaled corticosteroid. CONCLUSION: Pulmonologists in Turkey have low rates of adherence to GOLD guidelines in COPD treatment. Inappropriateness of therapies was due to overtreatment in early stages and excessive use of inhaled corticosteroid (ICS) in all disease stages.

RESUMEN

PURPOSE: Although obstructive sleep apnea (OSA) syndrome is a common disorder; the connection between OSA and smoking habits is still controversial. In this study, we investigated whether active smoking and pack × years of smoking have an impact on the severity of the disease regarding the patients with OSA. METHODS: This study included 964 patients referred to the Sleep Disorders Clinic between 01.01.2007 and 01.03.2013 with an overnight polysomnographic diagnosis of OSA. The correlation between smoking habits and polysomnographic parameters has been studied in detail. RESULTS: There were 684 male (79 %) and 280 female (21 %) patients, 367 (50.6 %) of whom never smoked. Of all, 20.7 % of the smokers were current smokers (n = 150) while 28.2 % were former smokers (n = 208). Active smokers had a mean age of 49.53 (SD 10.17) while former smokers and never smokers had a mean age of 51.37 (SD 10.62), 54.2 (SD 11.56), respectively, which was statistically significant (p < 0.0001). There was a significant male predominance in smoking (p < 0.0001). In addition, male patients displayed more severe OSA than female patients. (p = 0.001). Desaturation time during sleep was found to be significantly longer in the group of former smokers in comparison to never smokers (73.84 SD 97.1-52 SD 85.8) (p = 0.005). Besides, as the apnea hypopnea index increased, the mean pack × years rose significantly (p = 0.01). Severe smokers compared to mild smokers had higher AHI, lower NREM 3, higher NREM1-2 stages (p = 0. 017, p = 0.007, p < 0.001). CONCLUSION: In this study, we found that cigarette smoking was associated with early age disease; heavy smokers had more severe OSA.

RESUMEN

BACKGROUND: Exacerbations of COPD are a major component of the socioeconomic burden related to COPD, and frequent exacerbations are associated with greater decline in health status. Tracheobronchial infections are involved in 50-70% of exacerbations, so influenza and pneumococcal vaccines are recommended for prevention. The aim of this study was to determine the level of knowledge among COPD patients about the vaccines, find the rate of patients inoculated with both influenza and pneumococcal vaccines, and assess the effectiveness of vaccination status. METHODS: Patients with COPD were recruited from the out-patient clinic of our hospital between September and October 2012. Subject demographic data such as age, gender, level of education, and smoking status were recorded. Vaccination status, number of subjects who were informed by a health-care professional about immunization, and COPD-related emergency or hospital admissions triggered by tracheobronchial infections over 1 y after administration of both influenza and pneumococcal vaccines were noted. RESULTS: Eighty-eight subjects were enrolled during the study period. Eighty-two subjects were male (93.2%), 6 subjects were female (6.8%), and the median age was 61.5 y. According to Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2006 classification, 5 subjects were in stage 1 (5.7%), 22 subjects were in stage 2 (25%), 34 subjects were in stage 3 (38.6%), and 27 subjects were in stage 4 (30.7%). Sixty-two subjects had graduated from primary school (70.5%), 21 subjects had graduated from high school (23.9%), one subject had graduated from university (1.1%), and 4 subjects had no education (4.5%). Forty-five subjects (51%) were vaccinated. There was no significant correlation between level of education and vaccination status (P=.37). Both COPD-related emergency department and hospital visits were significantly decreased in vaccinated patients with COPD (P<.001 and P=.02, respectively). Of all the subjects, 39.7% (35 of 88 subjects) mentioned that no health-care professional recommended vaccination. CONCLUSIONS: Physicians should be more aware of vaccination and recommend both influenza and pneumococcal vaccines to all patients with COPD to reduce exacerbations.

RESUMEN

INTRODUCTION: Chronic thromboembolic pulmonary hypertension (CTEPH) is a curable and partially preventable complication, with a substantial incidence, leading to severe morbidity and mortality. The aim of the present study was to find out the incidence of CTEPH secondary to acute pulmonary thromboembolism (PTE) using non-invasive procedures such as ventilation/perfusion (V/Q) scintigraphy and pulmonary multidetector CT (MDCT) angiography in determining the diagnosis of CTEPH. MATERIALS AND METHODS: The study included a total of 99 patients diagnosed with initial PTE between January 2010 and December 2012. The patients who received anticoagulant therapy at least for three months underwent transthoracic echocardiography (TTE) (n= 85). Thirty one patients with a SPAP value > 30 mmHg and/or an evidence of right ventricular dysfunction in TTE underwent MDCT pulmonary angiography and V/Q scintigraphy. The patients with an evidence of residual chronic thromboembolic signs in MDCT pulmonary angiography and/or segmental perfusion defect(s) in V/Q scintigraphy underwent right heart catheterization (RHC) (n= 7). The mean PAP was measured, and a vasoreactivity test was performed. During RHC, a non-contrast medium was delivered to the pulmonary arteries for pulmonary arteriography imaging. RESULTS: Among patients diagnosed with PTE, 44 were male and 55 were female. The mean age was 60 ± 17 years. Of these patients, 63.6% had history of at least one additional disease and at least one risk factor for PTE. During diagnosis, 24 subjects were considered having massive, 61 submassive and 14 non-massive PTE. Nineteen (19.1%) patients received thrombolythic therapy. Other 80 (80.8%) patients received standard anticoagulant therapy with an INR value within the therapeutic range. In 79.8% of patients, thromboembolism was bilateral, and it was unilateral in 21.8%. After a minimum of 1 year, and maximum of 2 years follow up five subjects (5.5%) were diagnosed with CTEPH. The univariate analysis showed no association between the development of CTEPH and factors like; age, etiologic risk factors for PTE, receiving thrombolytic treatment, prevalence and type of PTE. CONCLUSION: Potentially preventabl complication of pulmonary embolism; CTEPH, had a substantial incidence during follow-up.

RESUMEN

Chronic obstructive pulmonary disease (COPD) is a lung disease characterized with limitation of airflow that is not completely reversible, progressive deterioration of airways and systemic inflammation. This study has been planned to determine daily symptom variability of patients, expectations of patient and physicians from treatment and patient profiles. A total of 514 patients with COPD from 25 centers were included in this national, multicenter, cross-sectional observational study. Data regarding demographic features, concomitant diseases, history and treatment of COPD and expectations of patients and physicians were all obtained in a single visit. Mean [standard deviation (SD)] age of the patients was 64.1 (9.5) years; age range was 41-92 years, 50% of the patients were younger than 65 years and 91% were males. Educational level of the patients was at least primary school in 80.2%; and 54.3% (30.4%) of the patients had at least one concomitant disease, particularly a cardiovascular disease. Mean (SD) duration of having COPD was 5.4 (4.6) years. The majority of patients were at moderate (43.2%) and severe (35.0%) COPD stages and one or more exacerbations per year was determined in 71%. Inhaled beta-2 agonists (84.2%), inhaled steroids (76.3%) and inhaled long-acting anti-cholinergics (70.0%) were the most commonly used medications. Dyspnea (99.0%), sputum production (92.8%) and wheezing (90.5%) were the most common symptoms, and symptom variability for dyspnea (41.1%), sputum production (61.0%) and cough (53.5%) were seen the most in the morning hours (p< 0.001). Most commonly affected morning activity was climbing up/down the stairs (point of effect: 6.7), followed by wearing socks/shoes (point of effect: 4.3) and showering/bathing (point of effect: 4.2) by COPD. Major treatment expectations of patients were greater symptomatic relief (82.3%) and greater mobility (70.0%), faster symptomatic relief (61.1%) and improvement in morning activities (59.3%); while major treatment expectations of physicians included increased quality of life (100.0%) and decreased morbidity (96.0%). Quitting smoking was the most commonly recommended (88.3%) and implemented (67.9%) non-drug protective approach aimed at decreasing the frequency of exacerbations. Consequently, our results demonstrate that COPD is not a disease of only the elderly, is an important healthcare issue that often disrupt daily living of the patients due to inadequate disease awareness leading to overlooking of the symptoms by patient and physicians, and that a patient-centered approach based on the living standards, life expectancies and preferences of patients was crucial in patient management.

RESUMEN

Fahr's disease occurs in relation with many metabolic disorders especially with hypoparathyroidism. Imbalance of the coordination system and dysarthria were seen at the end of the treatment in a lung cancer patient treated with radiotherapy and chemotherapy. Fahr's disease was diagnosed by diffuse symmetric calcifications at white matter and basal ganglia of cerebrum and cerebellum in cranial computed tomography. Disease was thought to be caused by hypoparathyroidism with lower calcium and parathyroid hormone levels. Possible factor that caused hipoparathyroidism and also of Fahr's disease was radiotherapy performed to a wide area because of lung cancer. This case is the first Fahr's disease that was diagnosed concurrently with lung cancer.

RESUMEN

FundamentoLa enolasa específica de neurona (EEN) es el marcador tumoral más sensible para el carcinoma de pulmón microcítico en el momento del diagnóstico. El objetivo del presente estudio fue revisar la utilidad de sus valores séricos como factor pronóstico en pacientes con este cáncer y determinar la correlación entre los valores y el estadio de la enfermedad y la respuesta a la quimioterapia.MétodosEn este estudio prospectivo, se evaluaron pacientes con carcinoma de pulmón microcítico para su respuesta a la quimioterapia, supervivencia sin progresión de la enfermedad y supervivencia global. El criterio de valoración se designó como la muerte del paciente debida a la enfermedad. Los análisis de EEN se efectuaron antes y después de completar la quimioterapia.ResultadosSe incluyeron en el estudio 65 pacientes. Los niveles de EEN fueron significativamente más altos en los pacientes que fallecieron de la enfermedad. En pacientes que respondieron al tratamiento los valores pretratamiento fueron significativamente más bajos. Los valores postratamiento no se correlacionaron significativamente con la respuesta a la quimioterapia, supervivencia libre de progresión, supervivencia global y pronóstico de los pacientes. El cambio de los valores de EEN entre el intervalo pre y postratamiento no se correlacionó significativamente con la respuesta al tratamiento, supervivencia libre de progresión y supervivencia global.ConclusionesLes posible que los valores de EEN no guarden relación con el estadio de la enfermedad. No obstante, en pacientes con carcinoma de pulmón microcítico, en la predicción de una respuesta apropiada a la quimioterapia pueden usarse unos valores bajos previos al tratamiento. Los valores séricos postratamiento y la tasa del cambio entre los valores pre y postratamiento no se relacionaron con la respuesta a la quimioterapia, supervivencia libre de progresión y supervivencia global(AU)


BackgroundNeuron-specific enolase (NSE) is the most sensitive tumor marker for small-cell lung carcinoma (SCLC) at the time of diagnosis. The main purpose of this study was to review the usefulness of serum NSE level as a prognostic factor in patients with SCLC and to determine the correlation between the NSE level and the stage of disease and response to chemotherapy.MethodsIn this prospective study, patients with SCLC were evaluated for response to chemotherapy, survival without disease progression, and overall survival. The end point was designated at patient death due to SCLC. NSE assays were performed before and after completion of chemotherapy.ResultsSixty-five patients were included in study. NSE levels were significantly higher in patients who died of SCLC. The pre-treatment NSE levels in patients who responded to treatment were significantly lower. The post-treatment NSE levels were not significantly correlated with response to chemotherapy, progression-free survival, overall survival, and prognosis of patients. Change in the NSE level between the pre- and post-treatment periods was not significantly correlated with response to treatment, progression-free survival, and overall survival.ConclusionsNSE levels might not be related with the stage of the disease. However, a low pre-treatment NSE level might be used in predicting good response to chemotherapy in patients with SCLC. The post-treatment serum NSE levels and the rate of change between pre- and post-treatment serum levels of NSE were not related with response to chemotherapy, progression-free survival, and overall survival(AU)

RESUMEN

BACKGROUND: Lactate may be useful in pointing out the higher risk subgroups in sleep-related breathing disorders (SRBD) with various patterns of hypoxemia. We aimed to search whether morning and night lactate levels are related to apnea-hypopnea, hypoventilation, and hypoxemia in patients with SRBD and to compare it with patients without SRBD (No-SRBD). METHODS: Eighty patients with suspected SRBD underwent polysomnography (PSG) testing. SRBD patients had obstructive sleep apnea syndrome with or without sleep-related hypoventilation/hypoxemic conditions. Patients without SRBD were in the control group. Measurements included pulmonary function testing, PSG, analysis of arterial blood gases, and arterial lactate before and after PSG. Arterial lactate was compared with SRBD and No-SRBD patients. RESULTS: Morning lactate was significantly higher in the SRBD group than the No-SRBD group (1.65 +/- 0.48 and 1.35 +/- 0.57 mmol/L, respectively) (P = 0.003). Lactate levels at night and the change overnight in lactate levels were not significantly different between groups. After an adjustment for age, gender, and body mass index, lactate levels before PSG were related to the apnea-hypopnea index (beta: 0.004, 95% CI: 0.000-0.008) and the rate of sleep-time spent under 90% oxygen saturation (T90%). The following morning lactate level was correlated with the T90% (beta: 0.005, 95% CI: 0.000-0.010). After an adjustment for lactate levels before PSG, lactate in the morning was correlated with T90% (beta: 0.004, 95% CI: 0.000-0.008). CONCLUSION: As a marker of tissue hypoxia, arterial lactate may be used to assess the severity of SRBD.
