OBJECTIVES: Published experiences with thoracoscopic apical or total pleurectomy for patients with a pneumothorax are limited. We aimed to evaluate the long-term results and effectiveness of pleurectomy in our patients, that vast majority of whom underwent thoracoscopic apical or total pleurectomy. MATERIAL AND METHODS: Between January 2001 and December 2010, in the Istanbul University Medical School Department of Thoracic Surgery, 67 patients, consisting of 52 patients with a primary spontaneous pneumothorax and 15 with a secondary spontaneous pneumothorax who underwent 72 processes of thoracoscopic resection of blebs or bullae and pleural symphysis, consisting of 43% total pleurectomy, 42% apical pleurectomy plus pleural abrasion, and 15% non-pleurectomy pleurodesis procedures due to prolonged air leak or recurrent spontaneous pneumothorax, were analyzed retrospectively. The applied pleural procedures were: 1. total pleurectomy 2. apical pleurectomy and pleural abrasion for the remaining parts and 3. non-pleurectomy pleurodesis procedures. The long-term outcomes of patients undergoing the three different pleural procedures were compared. RESULTS: Total pleurectomy process, apical pleurectomy and abrasion process for remaining parietal pleura, and non-pleurectomy pleurodesis procedures were performed 31, 30, and 11 times, respectively. No recurrence was observed in the total pleurectomy group, 1 recurrence was observed for the apical pleurectomy plus pleural abrasion group, and 2 recurrences were observed for the nonpleurectomy group. CONCLUSION: Video-assisted thoracoscopic pleurectomy is a safe and effective method in spontaneous pneumothorax surgery. Especially, total pleurectomy has efficient results in the prevention of recurrences. [ABSTRACT FROM AUTHOR]

OBJECTIVES The aim of this prospective study was to compare the effects of axillary thoracotomy (AT) and video-assisted thoracoscopic surgery (VATS) on acute-phase responses, pain, performance status and quality of life in patients undergoing pulmonary resection. METHODS Fifty-five patients with peripherally located lung lesions were enrolled into this study. Surgery was done by VATS or AT. Forced expiratory volume, smoking habits, complications, Charlson comorbidity index, sex, age, length of incision, length of operation, length of hospital stay, length of drainage, length of air leakage, preoperative and postoperative C-reactive protein (CRP) values, visual analogue scale, quality of life and performance status of the patients were measured and compared. RESULTS Twenty-five patients had lung resection with VATS and 30 patients had lung resection with AT. The demographic variables were similar. The differences between the two groups' postoperative serum CRP levels were significantly lower for the VATS group. The length of postoperative stay was significantly shorter for the VATS group. There were no other statistical significance between the two groups in terms of operative variables, complications, pain, quality of life and performance status. CONCLUSIONS AT is a technique equivalent to VATS in terms of early complications, pain, performance status and quality of life; VATS provided a shorter postoperative stay. [ABSTRACT FROM AUTHOR]

BACKGROUND: In patients being considered for lung-resection surgery, quantitative perfusion scintigraphy is used to predict postoperative lung function and guide the determination of lung-resection candidacy. Vibration-response imaging has been proposed as a noninvasive, radiation-free, and simpler method to predict postoperative lung function. We compared vibration-response imaging to quantitative perfusion scintigraphy for predicting postoperative FEV
1 and diffusing capacity of the lung for carbon monoxide (DLCO ). METHODS: We enrolled 35 candidates for lung resection. Twenty-five patients had preoperative FEV1 and DLCO measurements. RESULTS: The vibration-response-imaging measurements showed strong correlation with the quantitative-perfusion-scintigraphy measurements of predicted postoperative FEV1 % (r = 0.87, P < .001), predicted postoperative FEV1 (r = 0.90, P < .001), and predicted postoperative DLCO % (r = 0.90, P < .001). There was a correlation between predicted postoperative FEV1 (% and L) measured via quantitative perfusion scintigraphy and the actual postoperative FEV1 (% and L) (r = 0.47, P = .048, r = 0.73, P < .001). There was no difference between the vibration-response-imaging measurements and the actual postoperative measurements of predicted postoperative FEV1 (% and L). There was a correlation between predicted postoperative FEV1 (% and L) measured via vibration-response imaging and actual postoperative FEV1 (% and L) (r = 0.52, P = .044, r = 0.79, P < .001). The mean differences between the predicted and actual postoperative FEV1 values were 49 mL with vibration-response imaging, versus 230 mL with quantitative perfusion scintigraphy. Neither the vibration-response imaging nor the quantitative perfusion scintigraphy predicted postoperative DLCO % values agreed with the actual postoperative DLCO % values. CONCLUSIONS: Vibration-response imaging may be a good alternative to quantitative perfusion scintigraphy in evaluating lung-resection candidacy. [ABSTRACT FROM AUTHOR]- Published

- Abstract
This study aimed to analyze surgeons' learning curve for thymoma resection with video-assisted thoracoscopic surgery (VATS). Two hundred and eleven myasthenia gravis patients had VATS thymic resections, including 25 patients with a thymoma. Three groups of surgeries, according to the order of operations, were analyzed: Group A comprised the first 70 thymectomies, Group B comprised the second 70 thymectomies, and Group C comprised the final 71 thymectomies. We compared the groups on a set of preoperative (age, gender, body mass index, and Osserman stage), operative (number in each group, size, and Masaoka stage), and postoperative (complications and length of stay) variables. A significant difference was observed in the number of thymoma operations (Group A: four patients, Group B: seven patients, and Group C: 14 patients; P: 0.031) and the duration of operation (Group A: 66 min, Group B: 52 min, and Group C: 48 min; P: 0.024). A strong correlation was found between the duration of operation and order of patients (Pearson r: -0.554, P: 0.000). We recommend the start of a program for the resection of thymoma with VATS after surgical staff have performed 70 VATS thymectomy operations.

- Abstract
The aims of this study are to present the results of videothoracoscopic thymectomy in patients with myasthenia gravis (MG) and to predict the factors affecting the next morning discharge (NMD). This is a retrospective analysis of the prospectively recorded data of 181 consecutive myasthenic patients who underwent videothoracoscopic thymectomy from June 2002 to September 2009. Sixty-one patients (33.7%) were discharged on the next morning. Univariate and multivariate analyses were evaluated to determine the predictors for NMD. Mean calculated variables were: age (29.8 years), duration of symptoms (22.5 months), duration of surgery (51.3 min), postoperative stay (2.1) days, and visual analogue scale (2.1). No mortality occurred. Four patients were required to stay in intensive care unit (ICU) with a mean of 18.6 h. With logistic regression analysis, duration of operation (DoO) was calculated to be the only predictive factor for NMD (P=0.006). Video-assisted thoracoscopic thymectomy (VAT thymectomy) is a safe surgery procedure with a smooth postoperative period for MG. Although a detailed analysis was performed, only DoO was found to be a predictive factor for NMD in MG patients.

- Abstract
This prospective study was done between February 2001 and December 2002 on 84 non-small cell lung cancer patients who were apparently operable. We selectively performed mediastinoscopy to 46 patients (54.76%, group 1) with the following indications: clinical T4 tumor, high operative risk, radiologically enlarged mediastinal lymph nodes, clinical T3 tumors with central location, radiologically identified mediastinal lymph nodes of any size with adeno or large cell carcinoma histology. Other 38 patients (45.23%, group 2) underwent thoracotomy without mediastinoscopy. Sensitivity, specificity, negative predictive value and positive predictive value of the indications were calculated. Cost analysis was done in the 84 patients and the results were compared with alternative mediastinal staging strategies (vs. routine, and vs. selectively to patients with radiologically positive mediastinal lymph nodes) if they had been applied to our population. Group 1 had higher selectivity to differentiate N2 patients (p=0.02). Sensitivity, specificity, negative predictive value and positive predictive value of indications were calculated as: 0.85, 0.54, 0.92 and 0.36, respectively. Our approach was most economical in terms of total cost per patient and money spent unnecessarily per patient. Mediastinal evaluation in operable lung cancer patients should decrease the number of surgical procedures, N2 disease found at thoracotomy and cost.

THORACIC surgery , *ADENOCARCINOMA - Abstract
In this case report we present a novel treatment for bronchial fistula after lobectomy. The patient had right upper lobectomy for T1 N0 M0 peripheral adenocarcinoma and he had been reexplored 4 days later for massive air leak in another chest surgery department. After the reoperation the bronchial fistula persisted and the patient was admitted to our department. Nineteen days after the reoperation, bronchoscopy confirmed that the bronchial stump was totally opened. A sleeve resection to the right main broncus including the fistulous stump of right upper lobe was performed. [Copyright &y& Elsevier]

Extracellula r matri x (ECM)-derived hydrogels are in demand for use in lung tissue engineering to mimic the native microenvironment of cells in vitro. Decellularization of native tissues has been pursued for preser v i n g organotypic ECM while eliminating cellular content and reconstitution into scaffolds which allows re-cellularization for modeling homeostasis, regeneration, or diseases. Achieving mechanical stabi l i t y and understanding the effects of the decellularization process on mechanical parameters of the reconstituted ECM hydrogels present a challenge in the field. Stiffness and viscoelasticity are important characteristics of tissue mechanics that regulate crucial cellular processes and their in vitro representation in engineered models is a current aspiration. The effect of decellulariza-tion on viscoelastic properties of resulting ECM hydrogels has not yet been addressed. The aim of this study was to establish bovine lung tissue decellularization for the first time via pursuing four different protocols and characterization of reconstituted decellularized lung ECM hydrogels for biochemical and mechanical properties. Our data reveal that bovine lungs provide a reproducible alternative to human lungs for disease modeling with optimal retention of ECM components upon decellularization. We demonstrate that the decellularization method significa n t l y affects ECM content, stiffness, and viscoelastic properties of resulting hydrogels. Lastly, we examined the impact of these aspects on viabi l i t y , morphology, and growth of lung cancer cells, healthy bronchial epithelial cells, and patient-derived lung organoids., This work was funded by the International Fellowship for Outstanding Researchers Program of Scientific and Technological Research Council of Turkey (TÜBİTAK) (grant no. 118C238) and Marie Sklodowska-Curie Individual Fellowship (MiTuMi, grant no. 101032602).

Background/aim: programmed death ligand-1 (PD-L1) is a predictive marker for immunotherapeutic agents. However, heterogeneous staining of PD-L1 can cause false-negative results. The aim of this study is to evaluate the importance of histological patterns on PD-L1 staining heterogeneity in lung adenocarcinomas (LAC). Materials and methods: PD-L1 immunohistochemistry (IHC) stain was performed to two different tissue cores of 128 LAC cases, and cut-off values are given for grouping the cases according to the percentage of staining (1%-10%, 11%-49%, 50%-100%). Staining rates between cores were compared and analyzed by their histological patterns. Also, the relation of the PD-L1 expression with the clinicopathological characteristics of the cases was analyzed. Results: overall, PD-L1 expression was observed in 53 of 128 cases (41.4%, 1% cut-off), 23.5% of them were positive at 10% cut-off and 14.1% at 50% cut-off. PD-L1 expression was significantly related to the high grade micropapillary and solid patterns of adenocarcinomas (p:0.01). Staining cut-offs were mostly similar between cores (43/50, 86%) (k:0.843). However, 14% of them were positive only in one core (7 of 50). This false negativity was mostly related to the histological patterns. Conclusion: our data reveal the heterogeneous staining of PD-L1 expression, also micropapillary and solid patterns show higher rates of PDL expression. Therewithal, these findings also highlight the importance of taking into consideration of histological patterns, when choosing a paraffin block for the PDL1., NA

Background: we aimed to assess the feasibility and short-term clinical outcomes of surgical procedures for cancer at an institution using a coronavirus disease 2019 (COVID-19)-free surgical pathway during the peak phase of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Materials and methods: this was a single-center study, including cancer patients from all surgical departments, who underwent elective surgical procedures during the first peak phase between March 10 and June 30, 2020. The primary outcomes were the rate of postoperative SARS-CoV-2 infection and 30-day pulmonary or non-pulmonary related morbidity and mortality associated with SARS-CoV-2 disease. Results: four hundred and four cancer patients fulfilling inclusion criteria were analyzed. The rate of patients who underwent open and minimally invasive procedures was 61.9% and 38.1%, respectively. Only one (0.2%) patient died during the study period due to postoperative SARS-CoV2 infection because of acute respiratory distress syndrome. The overall non-SARS-CoV2 related 30-day morbidity and mortality rates were 19.3% and 1.7%, respectively; whereas the overall SARS-CoV2 related 30-day morbidity and mortality rates were 0.2% and 0.2%, respectively. Conclusions: under strict institutional policies and measures to establish a COVID-19-free surgical pathway, elective and emergency cancer operations can be performed with acceptable perioperative and postoperative morbidity and mortality., NA

PLEURAL effusions , *RESPIRATORY aspiration , *HEMORRHAGE - Abstract
A 54-year-old male patient was admitted to our department with fever, dyspnea and chest pain. Left pleural effusion and destroyed left lower lobe was noticed in his computerized chest tomography. After chest tube drainage, massive hemoptysis developed. An emergency thoracotomy was performed. A bronchopleural fistula, destroyed left lower lobe and the head of an oat were detected in the pleural space. Left lower lobectomy and perioperative pneumoperitoneum were performed. The patient had an uneventful postoperative (p.o.) course and was discharged on p.o. day 6. We present this case because of the rarity and to emphasize the clinical presentation. The physicians should be aware of life threatening complications of oat head aspiration. [Copyright &y& Elsevier]

Objectives: Whether acute phase and immune responses are minimally affected following minimally invasive lung surgery needs further investigation. We performed a pilot study to evaluate the immune profile of patients who underwent video-assisted thoracoscopic surgery or robot-assisted thoracic surgery lobectomies for the treatment of suspicious or known stage I non-small-cell lung cancer. Methods: blood samples were taken preoperatively and 3 and 24 h postoperatively were analysed for C-reactive protein, glucose, cortisol, tumour necrosis factor alpha (TNF-α), interleukin 8 (IL-8) and interleukin 10 (IL-10) levels. TNF-α, IL-8 and IL-10 were also measured in lung tissues. T (CD4, CD8), B (CD19) and natural killer (CD56, CD16) cell counts and natural killer cell functions were analysed using a flow cytometry-based assay before and after surgery. Results: minimally invasive surgery (robot-assisted thoracic surgery + video-assisted thoracoscopic surgery) significantly decreased IL-10 (P = 0.016) levels after surgery. No significant differences were detected in TNF-α (P = 0.48) and IL-8 (P = 0.15) levels before and after surgery. C-reactive protein (P < 0.001), cortisol (P < 0.001) and glucose levels (P < 0.001) increased significantly after surgery. Lymphocyte, total T cell, CD3+CD4+ and CD3+CD8+ CD16+CD56+ cell counts were significantly lower on postoperative day 1. Conclusion: there seems to be a dynamic balance between pro- and anti-inflammatory cytokines and immune cells following minimally invasive lobectomy., Scientific and Technological Research Council of Turkey (TÜBİTAK)

Malignant pleural mesothelioma (MPM) arises from mesothelial cells lining the pleural cavity of asbestos-exposed individuals and rapidly leads to death. MPM harbors loss-of-function mutations in BAP1, NF2, CDKN2A, and TP53, but isolated deletion of these genes alone in mice does not cause MPM and mouse models of the disease are sparse. Here, we show that a proportion of human MPM harbor point mutations, copy number alterations, and overexpression of KRAS with or without TP53 changes. These are likely pathogenic, since ectopic expression of mutant KRAS(G12D) in the pleural mesothelium of conditional mice causes epithelioid MPM and cooperates with TP53 deletion to drive a more aggressive disease form with biphasic features and pleural effusions. Murine MPM cell lines derived from these tumors carry the initiating KRAS(G12D) lesions, secondary Bap1 alterations, and human MPM-like gene expression profiles. Moreover, they are transplantable and actionable by KRAS inhibition. Our results indicate that KRAS alterations alone or in accomplice with TP53 alterations likely play an important and underestimated role in a proportion of patients with MPM, which warrants further exploration., European Union (EU); Horizon 2020; European Research Council 2010 Starting Independent Investigator; ERC Proof of Concept 2015 (ERC-PoC-2015); German Research Society; ALTERNATIVE; German Ministry for Education and Research; German Center for Lung Research Translational Research Grant; Greek State Scholarship Foundation Program; European Union (EU); European Union Social Fund; Greek National Fund; Reinforcement of Postdoctoral Researchers-1 stand 2nd cycles; General Secretariat for Research and Innovation; Hellenic Foundation for Research and Innovation; REPSIRE European Respiratory Society Fellowship; Institut National de la Sante et de la Recherche Medicale (INSERM); Centre National de la Recherche Scientifique (CNRS); Institut de Recherche en Sante Respiratoire des Pays de la Loire; National Research Agency Programme d' Investissements d' Avenir; Pays de la Loire Region Research Program; Ligue Contrele Cancer; Chancellerie des Universites de Paris; Projekt DEAL

Objectives: Some of the lung cancer patients who are treated surgically with curative intent ultimately die in the early postoperative period. The aim of this study is to analyze the causes of death within 1 year of resection for lung cancer in our patients. Methods: Six hundred and twenty patients, who underwent resection for lung cancer with a curative intent were reviewed retrospectively. Eighteen patients (2.9%) died due to postoperative complications or within the first month and 51 (8.4%) patients (group 1) died within the first year after operation. Fifty-one patients (group 1) were compared with the survivors (group 2) in terms of age, gender, preoperative FEV 1, pathological tumor node metastasis (TNM), histopathological subtypes, type of resection, completeness of the resection, preoperative Karnofsky performance status and application of postoperative radiotherapy. Results: Pathological TNM
(P<0.001), type of resection(P<0.01), histopathological subtype(P<0.001), completeness of the resection(P<0.05) and postoperative radiotherapy(P<0.001) were determined to be significant factors in mortality within 1 year after resection for lung cancer. Conclusions: The patients with pathological stage 3 disease, with large cell histology or who had undergone pneumonectomy have a higher risk of mortality within 1 year. These patients require detailed preoperative work up in terms of metastatic disease and cardiopulmonary physiological status. [Copyright &y& Elsevier]- Published

Purpose: One of the key immune cells involved in the pathogenesis of lung cancer is natural killer (NK) cells and these cells are novel targets for therapeutic applications in lung cancer. The purpose of this review is to summarize the current literature on lung cancer pathogenesis with a focus on the interaction between NK cells and smoking, how these factors are related to the pathogenesis of lung cancer and how NK cell-based immunotherapy effect lung cancer survival. Methods: The relevant literature from PubMed and Medline databases is reviewed in this article. Results: The cytolytic potential of NK cells are reduced in lung cancer and increasing evidence suggests that improving NK cell functioning may induce tumor regression. Recent clinical trials on NK cell-based novel therapies such as cytokines including interleukin (IL)-15, IL-12 and IL-2, NK-92 cell lines and allogenic NK cell immunotherapy showed promising results with less adverse effects on the lung cancer survival. Conclusions: The NK cell targeting strategy has not yet been approved for lung cancer treatment. More clinical studies focusing on the role of NK cells in lung cancer pathogenesis are warranted to develop novel NK cell-based therapeutic approaches for the treatment of lung cancer., NA

Background: The aim of this case report is to discuss diagnostic workup and clinical management of cytomegalovirus reactivation in a critically ill immunocompetent pediatric patient. Case presentation: A 2-year-old white boy who had no medical history presented with respiratory distress and fever. His Pediatric Risk of Mortality and Pediatric Logistic Organ Dysfunction scores were 20 and 11, respectively. Our preliminary diagnosis was multiple organ dysfunction secondary to sepsis. Antibiotic treatment was started; he was intubated and artificially ventilated. Norepinephrine infusion was started. Hemophagocytic lymphohistiocytosis was diagnosed because our patient had elevated levels of serum ferritin, bicytopenia, splenomegaly, fever (> 38.5 °C), and hemophagocytosis shown in a bone marrow sample. Therapeutic plasma exchange and intravenously administered high-dose corticosteroid for hemophagocytic lymphohistiocytosis and continuous renal replacement treatment for acute renal failure were initiated. Following 5-day high-dose corticosteroid administration, therapeutic plasma exchange, and continuous renal replacement treatment, his clinical status and kidney and liver functions improved, and vasoactive requirement and ferritin levels decreased. He was extubated on the seventh day. On the tenth day of hospitalization he had a seizure and was diagnosed as having septic encephalopathy. His immune functions were found to be normal. Although his medical condition improved continuously, he had left spontaneous pneumothorax on the 21st day of admission as a complication of necrotizing pneumonia. Since pneumothorax persisted, left upper lobectomy surgery was performed on the 30th day of hospitalization. In the pathological examination of the excised lung tissue, features of cytomegalovirus infection were observed. Ganciclovir treatment was started. Serological tests indicated that our patient had cytomegalovirus reactivation. Antiviral treatment was stopped after 17 days, when cytomegalovirus deoxyribonucleic acid (DNA) polymerase chain reaction results became negative. He fully recovered and was discharged on the 50th day of admission. Conclusions: Cytomegalovirus reactivation in critically ill patients is a prevalent problem and shown to be associated with higher mortality and morbidity. In a case of serologic detection of cytomegalovirus reactivation without any clinical sign of infection, pre-emptive treatment could be considered with assessment of risks and benefits for each patient. Antiviral therapy is highly recommended for patients who have risk factors identified., NA

- Abstract
Purpose: The benefit of adjuvant chemotherapy for tumors smaller than 4 cm is not clear. We aimed to evaluate the prognostic impact of adjuvant platin-based chemotherapy in high-risk stage I patients with non-small cell lung cancer (NSCLC)., Methods: This cooperative group study included 232 NSCLC patients who underwent curative surgery for stage I disease with tumor size 2-4 cm. Re ults: Median age at presentation was 63 years (range 18-90). The mean tumor size was 29.6 ± 7.3 mm. The frequency of patients with specified risk factors were: visceral pleural effusion (VPI): n: 82 (36.6%); lymphovascular invasion (LVI): n: 86 (39.1%); Grade 3: n: 48 (32.7%); Solid micropapillary pattern (SMP): n: 70 (48.3%). Adjuvant platin-based chemotherapy was administered to 51 patients. During a median follow-up period of 50.5 months 68 patients (29.3%) developed recurrence, 54 (23.3%) died from any cause and 38 (16.4%) of them died of lung cancer. Patients who received chemotherapy compared with the non-chemotherapy group had a longer 5-years relapse-free survival (RFS) (84.5 vs 61.1%). Also on multivariate analysis, adjuvant chemotherapy was a significant independent prognostic factor for RFS., Conclusion: Adjuvant platin-based chemotherapy should be considered for patients with small tumors with adverse risk factors. Key words: adjuvant chemotherapy, lung cancer, oncology, lymphovascular invasion, solid-micropapillary pattern, platinum-based therapy.

- Abstract
Purpose: Cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) or hyperthermic intrapleural chemotherapy (HIC) has been established as the new treatment modality for selected patients with peritoneal and pleural malignancies. The purpose of the study was to compare the development of acute kidney injury (AKI) in patients who received intravenous cisplatin alone, HIPEC and underwent surgery., Methods: This retrospective study included 104 patients who underwent different therapeutic procedures including systemic cisplatin, surgery and HIPEC or HIC using cisplatin for the treatment of peritoneal carcinomatosis from a variety of primary tumors at Koc University Hospital and American Hospital between January 2015 to December 2017., Results: AKI developed in 18 (17.3%) patients. Baseline creatinine was significantly increased in 3 groups after therapies. The development of AKI was highest in patients treated with HIPEC compared to patients treated with intravenous cisplatin and patients who underwent surgery. AKI developed 31.2% in the HIPEC group (10 of 32 patients), 11.7% in the surgery group (4 of 34 patients) and 10.5% in intravenous cisplatin group (4 of 38 patients), respectively (p 0.04)., Conclusion: HIPEC may not be so safe with regard to kidney function. Every attempt should be taken to decrease kidney damage during this procedure.

- Abstract
Lung cancer, a major health problem affecting the epithelial lining of the lower respiratory tract, is considered to be one of the deadliest types of cancer in males and females and it is well-known that smoking is the chief cause of lung cancer. In addition to smoking and environmental factors, genetic susceptibility may also contribute to the development of lung cancer. Previous studies have shown that certain non-small cell lung cancer (NSCLC) patients harbor gain-of-function mutations in the epidermal growth factor receptor gene (EGFR). Phosphorylated EGFR triggers the activation of intracellular signal transduction pathways, including the RAS-MAPK, PI3K-Akt and STAT pathways. However, K-Ras gene point mutations in codons 12, 13 or 61 cause the inactivation of GTPase activity which results in overstimulation of cellular growth and gives rise to neoplastic development. Our aim was to investigate the presence and association of EGFR and K-Ras mutations in 50 primary NSCLC patients with a smoking history by using real-time PCR and sequencing. EGFR mutations were detected in four patients (8%). Two of these mutations were L858R mutations and the remaining two were deletion mutations spanning between codons 746 and 750. The L858R mutation was significantly associated with smoking status (P=0.003). K-Ras codon 12 and 61 mutations were also observed in four patients. However, no association was observed between K-Ras mutations and the tumor staging, gender, histology and smoking status of the patients.
