RESUMEN
BACKGROUND: The use of laryngeal mask airway (LMA) ventilation in surgeries to be performed in upper tracheal stenosis has been reported in the case series. However, there is no generally accepted standardized approach for the use of LMA. In this study, LMA usage areas and advantages of trachea surgery were examined. METHODS: The records of 21 patients who underwent tracheal surgery using LMA ventilation between March 2016 and May 2020 were evaluated retrospectively. The patient data were analyzed according to age, gender, mean follow-up time, surgical indication, mean tracheal resection length, anastomosis duration, mean oxygen saturation, mean end-tidal CO2 levels, and postoperative complications. RESULTS: Four patients were female and 17 were male, their median age was 43 (11-72 range) and the mean follow-up time was 17.6 months. The most common surgical indication was postintubation tracheal stenosis. The mean tracheal resection length was 26.6 mm and the mean anastomosis duration was 11.3 minutes. The mean pulse oximetry and mean end-tidal CO2 during laryngeal mask ventilation was 97.6% ± 2.1 and 38.1 ± 2.8 mm Hg, respectively. Postoperative complications were higher in patients with comorbidities. CONCLUSION: LMA-assisted tracheal surgery is a method that can be used safely as a standard technique in the surgery of benign and malignant diseases of both the upper and lower airway performed on pediatric patients, patients with tracheostomy, and suitable patients with tracheoesophageal fistula.

Background/aim: As the number of case reports related to the new type of coronavirus (COVID-19) increases, knowledge of and experience with the virus and its complications also increase. Pleural complications are one relevant issue. We aimed in this study to analyze pleural complications, such as pneumothorax, pneumomediastinum, and empyema, in patients hospitalized with the diagnosis of COVID-19 pneumonia. Materials and methods: The files of patients who have pleural complications of COVID-19 pneumonia and were consulted about thoracic surgery between March 2020 and December 2020 were retrospectively reviewed. The data of the patients were analyzed according to age, sex, length of stay, treatment method for pleural complications, mortality, severity of COVID-19 pneumonia, tube thoracostomy duration, and presence of a mechanical ventilator. Results: A total of 31 patients fulfilling the inclusion criteria were included in the study. There were 11 female (35.5%) and 20 male (65.5%) patients. The most common complication was pneumothorax in 20 patients (65%). The median duration of hospitalization was 22 days and the mortality rate was 71%. Mortality was significantly higher in patients on mechanical ventilation (p = 0.04). Conclusion: The mortality rate is very high in patients with pleural complications of COVID-19 pneumonia. Pneumothorax is a fatal complication in critically ill patients with COVID-19 pneumonia.

OBJECTIVE: The aim: Gamma-glutamyl transferase (GGT) is a membrane-dependent enzyme and is primarily involved in glutathione metabolism. While a correlation between high GGT levels and oxidative stress, cardiovascular diseases, and some cancers has been shown in the literature, its prognostic ef f ect in patients with non-small-cell lung cancer remains unclear. The aim of this study was to investigate the correlation between the preoperative GGT levels and the prognosis of non-small-cell lung cancers treated surgically. PATIENTS AND METHODS: Materials and methods: Following the approval of the loc al ethics committee, the medical records of patients surgically treated in our department for stage-I non-small-cell lung cancer between January 2010 and December 2019 were retrospectively reviewed. The patients were classif i ed into a high group (high-GGT) and low group (low-GGT) according to the preoperative GGT cut-of f levels, which were specif i c to our series and calculated by receiver operating characteristic (ROC) analysis. Survival dif f erences between the groups were also investigated by Kaplan-Meier, log-rank, and Cox regression tests. RESULTS: Results: A total of 219 patients fulf i lled the inclusion criteria and were included in the study. The median survival was 75 (range: 58.4-91.1) months in the high-GGT group and 91 (range: 85-96.8) months in the low-GGT group, and this dif f erence was statistically signif i cant (Hazard Ratio: 2.0, 95% CI 1.0-3.9, p = 0.03). CONCLUSION: Conclusions: Preoperative GGT may be an inexpensive and easily applicable prognostic indicator in early-stage non-small-cell lung cancers.

Although bronchial sleeve resections were previously defined as an alternative technique to pneumonectomy for patients with limited pulmonary reserve, currently these resections are applied as a standard even in patients having normal pulmonary capacity. Pneumonectomy, itself, is a disease, and sleeve lobectomies can be performed without compromising oncological principles and without causing significant morbidity and mortality. In parallel with the developments in surgical techniques, bronchial sleeve resections can be performed by videothoracoscopic and robotic surgeries. Major complications in sleeve lobectomies are bronchial dehiscence, bronchopleural fistulas, and broncho-arterial fistulas. Late complications are bronchial stenosis and tumor recurrence.
RESUMEN
The optimum treatment option is surgery for clinical early stage non-small cell lung cancer. Despite all non-invasive and invasive staging effort, occult lymph-node metastasis can be detected in pathological staging. Here, we investigated whether there was any correlation between tumor diameter and occult lymph-node metastasis in N1 stations. Data of patient with non-small cell lung cancer clinical stage 1A were reviewed retrospectively. Those with tumor diameter smaller than 3 cm and pN0-pN1 in pathological staging were included in the study. Overall survival (OS) was calculated by Kaplan-Meier and survival differences between pN0 and pN1 groups were investigated by Log-Rank methods. Cut-off value of tumor diameter for lymph-node metastasis was investigated by Receiver-Operating Characteristics test. Significance between pN0-pN1 and other categorical groups was investigated with Pearson Chi-square or Fisher's exact tests. A total of 257 patients meet to criteria included in the study. Fifty-five (21.4%) of the patients were females. The mean age was 62.7 ± 8.5 and median tumor diameter was 20 mm (Range: 2-30 mm). We detected occult lymph-node metastasis at the N1 stations (pN1) in 33 patients (12.8%) in histopathological examination of resected specimens and lymph-node dissection materials. The cut-off value of tumor diameter was calculated as 21.5 mm for occult lymph-node metastasis by Receiver-Operating Characteristics analysis (Area Under Curved: 70.1%, p = 0.004). There was a significant correlation between pN1 positivity and high tumor diameter (p = 0.02). However, we did not find a correlation between the lymph-node metastasis and age, gender, tumor histopathology, tumor localization, and visceral pleural invasion. Tumor diameter may be an indicator for occult lymph-node metastasis in patients with clinical stage-1A non-small cell lung cancer. This result should be considered in patient with mass which larger than 21.5 mm and planned stereotactic body radiotherapy instead of surgery.

Objectives: Regular follow-up of patients with lung cancer treated surgically is crucial to detect local recurrence or distant metastasis of the tumor. Postoperative follow-ups are performed with thorax computed tomography (CT) and, if necessary, positron emission tomography (PET)/CT. Sometimes, inflammatory tissue reactions due to the materials used during the surgery for hemostasis may cause the appearance of tumor recurrence in imaging modalities. In this study, we presented that oxidized regenerated cellulose (ORC) used intraoperatively may cause false tumor recurrence on PET/CT. Methods: The records of patients who had local tumor recurrence after lung cancer surgery was reviewed retrospectively. Inclusion criteria were the presence of local recurrence of cancer on PET/CT, specification of using ORC in the surgical notes, and histopathological diagnosis of the recurrence site of tumor was reported as a foreign body reaction. Data of patients were collected according to age, gender, surgery performed, adjuvant therapy status, resolution status and time ORC, and standard uptake value of 18F-fluorodeoxyglucose on PET/CT. Results: Eleven patients (1 female, 10 males) who met the criteria were included in the study. The median age was 64. Histopathological results of all patients were reported as foreign body reactions. The median detection time of PET/CT positivity after surgery was 139 days (range: 52-208 days). False tumor recurrence was resolved in 8 patients (72.7%) in their control radiological examinations and median resolution time was 334 days (range: 222-762 days). The median maximum standard uptake value of the lesions was 6.2 (1.7-11) on the PET/CT. Conclusion: ORC used intraoperatively in patients undergoing surgery for lung cancer may cause false tumor recurrence in imaging modalities in postsurgical follow-ups. When tumor recurrence is suspected in the follow-up of these patients, histopathological confirmation is necessary to prevent unnecessary operations and treatments.
RESUMEN
Background: Malignant pleural mesothelioma (MPM) is an aggressive pleural malignancy, and despite all multimodal treatment modalities, the 5-year overall survival rate of patients with MPM is less than 20%. In the present study, we aimed to analyze the surgical and prognostic outcomes of patients with MPM who received multimodal treatment. Methods: In this retrospective, single-center study, the records of patients who underwent surgery for MPM between January 2010 and December 2020 at our department were reviewed retrospectively. Results: Sixty-four patients were included in the study, of whom 23 (35.9%) were women and 41 (64.1%) were men. Extrapleural pneumonectomy, pleurectomy/decortication, and extended pleurectomy/decortication procedures were performed in 34.4%, 45.3%, and 20.3% of patients, respectively. The median survival of patients was 21 months, and the 5-year survival rate was 20.2%. Advanced tumor stage (hazard ratio [HR], 1.8; p=0.04), right-sided extrapleural pneumonectomy (HR, 3.1; p=0.02), lymph node metastasis (HR, 1.8; p=0.04), and incomplete multimodal therapy (HR, 1.9; p=0.03) were poor prognostic factors. There was no significant survival difference according to surgical type or histopathological subtype. Conclusion: Multimodal therapy can offer an acceptable survival rate in patients with MPM. Despite its poor reputation in the literature, the survival rate after extrapleural pneumonectomy, especially left-sided, was not as poor as might be expected.
RESUMEN
BACKGROUND: Primary pulmonary malignant mesenchymal tumors are rare, constituting only 0.4% of all lung cancers. Since sarcomas are chemo/radio-resistant, surgical resection is the optimal treatment choice for patients with suitable medical conditions and tumor stage. In the present study, we analyzed the surgical outcomes and survival of primary pulmonary malignant mesenchymal tumors treated surgically. METHODS: We retrospectively examined the records of patients with primary pulmonary malignant mesenchymal tumors who underwent surgical resection at our department between January 2010 and December 2020. Patient data were analyzed according to age, sex, tumor grade and stage, resection completeness, surgical type, and tumor histopathology. RESULTS: Twenty patients were included in the study. There were 13 men (65%) and 7 women (35%). The median survival rate was 36 months (range, 19-53 months), and the 5-year overall survival rate was 37%. Unfavorable prognostic factors for overall survival included parietal pleural invasion (p=0.02), high tumor grade (p=0.02), advanced tumor stage (p=0.02), and extensive parenchymal resection (pneumonectomy and bilobectomy, p=0.01). The median length of disease-free survival was 31 months (interquartile range, 21-41 months), and the 5-year disease-free survival rate was 32%. The most unfavorable prognostic factors for recurrence were parietal pleural invasion (p=0.02), high tumor grade (p=0.01), and tumors requiring lung resection with chest wall resection (p=0.02). CONCLUSION: Primary malignant mesenchymal lung tumors are aggressive and have a high mortality rate. However, acceptable overall and disease-free survival rates can be obtained with surgical therapy.
RESUMEN
PURPOSE: The aims of this study were to evaluate the relationships between textural features of the primary tumor on FDG PET images and clinical-histopathological parameters which are useful in predicting prognosis in newly diagnosed non-small cell lung cancer (NSCLC) patients. METHODS: PET/CT images of ninety (90) patients with NSCLC prior to surgery were analyzed retrospectively. All patients had resectable tumors. From the images we acquired data related to metabolism (SUVmax, MTV, TLG) and texture features of primary tumors. Histopathological tumor types and subgroups, degree of Ki-67 expression and necrosis rates of the primary tumor, mediastinal lymph node (MLN) status and nodal stages were recorded. RESULTS: Among the two histologic tumor types (adenocarcinoma and squamous cell carcinoma) significant differences were present regarding metabolic parameters, Ki-67 index with higher values and kurtosis with lower values in the latter group. Textural heterogeneity was found to be higher in poorly differentiated tumors compared to moderately differentiated tumors in patients with adenocarcinoma. While Ki-67 index had significant correlations with metabolic parameters and kurtosis, tumor necrosis rate was only significantly correlated with textural features. By univariate and multivariate analyses of the imaging and histopathological factors examined, only gradient variance was significant predictive factor for the presence of MLN metastasis. CONCLUSIONS: Textural features had significant associations with histologic tumor types, degree of pathological differentiation, tumor proliferation and necrosis rates. Texture analysis has potential to differentiate tumor types and subtypes and to predict MLN metastasis in patients with NSCLC.

BACKGROUND: Although lung sarcomatoid carcinomas (LSCa) arised from the epithelial tissue, they have very distinctive features than other non-small cell lung carcinomas in terms of histopathology and survival. It constitutes 0.1%-0.4% of all lung cancers. The aim of our study is to evaluate the survival analysis of LSCa in a single thoracic surgery clinic and to determine the prognostic factors. MATERIALS AND METHODS: It was a retrospective cohort study. After the approval of the local ethics committee, a total of 34 patients who were operated in our department between January 2010 and December 2018, whose pathologies were reported as sarcomatoid carcinoma was included in the study. The patients were analyzed by age, gender, presence of necrosis in the histopathological examination, tumor stage, tumor diameter, and tumor location. RESULTS: There were 28 males and 6 females. The median age was 60 years (range: 36-80 years). The median survival was 42 months (32.6-52.2 months), and the 5-year overall survival was 33.6%. Significantly negative prognostic factors were tumor diameter and tumor stage (P = 0.003 and 0.001, respectively). Median disease-free interval (DFI) was 38 months (27.3-49.1 months), and 5-year DFI was 32.6%. CONCLUSION: LSCa are highly heterogeneous epithelial malignancies, and it has worse survival than other epithelial cancers. Relatively, satisfactory results can be obtained in these tumors with surgical treatment.
RESUMEN
BACKGROUND: This study aims to identify the prognostic factors in Stage IIIA non-small cell lung cancer and to investigate whether there was a significant difference in terms of overall survival and diseasefree survival among the subgroups belonging to this disease stage. METHODS: Between January 2010 and December 2018, a total of 144 patients (125 males, 19 females; median age 60 years; range, 41 to 80 years) who were operated for non-small cell lung cancer in our clinic and whose pathological stage was reported as IIIA were retrospectively analyzed. Data including demographic and clinical characteristics of the patients, histopathological diagnosis, the standardized uptake value of the mass on positron emission tomography-computed tomography, tumor diameter, type of surgery, lymph node metastasis status, visceral pleural invasion, and overall and disease-free survival rates were recorded. RESULTS: The median survival was 39 (range, 27.8 to 46.1) months and the five-year overall survival rate was 28%. The mean tumor diameter was 4.3±2.7 cm. The median disease-free survival was 37 (range, 28.1 to 48.6) months and the five-year disease-free survival rate was 26.9%. In the multivariate analysis, overall survival and disease-free survival in T2N2M0 subgroup were significantly worse than the other subgroups. The other poor prognostic factors of survival were the standardized uptake value of the tumor, pneumonectomy, and histopathological subtypes other than squamous cell carcinoma and adenocarcinoma. Parietal pleural invasion was significantly associated with worse disease-free survival rates. CONCLUSION: Our results showed that there may be significant survival differences between subgroups created by tumor histopathology, lymph node invasion and the type of surgery in a heterogeneous lung cancer stage.
RESUMEN
BACKGROUND: In this study, we aimed to evaluate the success of surgery and a complete resection for bronchiectasis treatment and to present our 23 years of surgical experience. METHODS: Between January 1991 and December 2013, a total of 1,357 patients (667 males, 690 females; mean age 30.5±14.3 years; range, 3 to 73 years) with the diagnosis of bronchiectasis who underwent pulmonary resection in our clinic were retrospectively analyzed. Demographic and clinical characteristics of the patients, etiologies, symptoms, localizations, surgical procedures, and long-term follow-up results were evaluated. RESULTS: There were 1,394 surgeries, as 37 (2.7%) patients had bilateral disease. The surgical procedures included lobectomy (n=702, 50.3%), pneumonectomy (n=183, 13.1%), segmental resections (n=114, 8.2%), bilobectomy (n=83, 6.0%), and lobectomy + segmentectomy (n=312, 22.4%). During the postoperative period, 1,269 (93.5%) patients were followed at a mean duration of 51.6 (range, 1 to 120) months. After surgery, 774 (61%) patients were asymptomatic, 456 (35.9%) showed an improvement, and 39 (3.1%) had no response or deterioration. CONCLUSION: The surgical treatment plays an important role in the clinical and symptomatic improvement of patients with bronchiectasis. Surgery reduces the morbidity and mortality rates with careful preoperative preparation and appropriately selected cases.
RESUMEN
BACKGROUND: Lung cancer is a typical disease of elderly patients. While there are many publications in the literature on factors affecting survival, there is still no consensus on the survival impact of lymph node dissection. Our objective in this study was to evaluate prognostic factors influencing rates of complications, mortality, and survival in geriatric patients who underwent surgery for non-small cell lung cancer. MATERIALS AND METHODS: Data obtained from the medical records of patients aged 70 years or older with early-stage non-small cell lung cancer who underwent surgery between January 01, 2008 and December 31, 2015 were evaluated retrospectively. RESULTS: Of the 72 patients included, 57 (79.2%) were male and 15 (20.8%) were female. Complications were observed in 42 patients (58.3%). Nineteen patients (26.4%) developed major complications. Percent predicted forced expiratory volume in 1 s (ppFEV1) and age was found to be risk factors for complications. Thirty days days mortality rate was 8.3%. Mortality was not significantly associated with low CCI, physical status, and ppFEV1 values. The 5-year survival rate was 40.5%. ppFEV1 were risk factors affecting survival, whereas radical lymph node dissection was not associated with survival. CONCLUSION: The main prognostic factors affecting long-term postoperative survival in the present study was a low postoperative ppFEV1 value. Radical lymph node dissection did not increase the risk of postoperative complications and it did not affect long-term survival in patients aged 70 years or older. A key finding was that comorbidities were not associated with postoperative complications or long-term survival.

Objectives Transcutaneous electrical nerve stimulation has been used to control post-thoracotomy pain, with conflicting results. We aimed to assess its efficacy on post-thoracotomy pain and early complications. Methods Between January 2012 and December 2014, 87 patients underwent a standard posterolateral thoracotomy and were randomized in 2 groups: group T was 43 patients who had transcutaneous electrical nerve stimulation and group C was 44 patients who had placebo stimulation with an inoperative device. Pain score was measured using a visual analogue scale ranging from 0 to 10. The frequency of the device was set at 100 Hz and pulse width at 100 ms. Results There were no statistically significant differences in the demographic characteristics of the 2 groups, and there was no difference in the duration of hospitalization (4.74 ± 1.6 vs. 5.23 ± 1.5 days; p = 0.06). Postoperative pain scores of the two groups showed that on postoperative day 0, 1, and 2, the mean pain scores of group T were significantly lower ( p = 0.001, p < 0.001, and p = 0.003). There were no significant differences in early complications or surgical technique. Conclusion We concluded that electrical stimulation is a safe and effective adjunctive therapy for acute post-thoracotomy pain control. However, it does not affect the duration of hospitalization or early pulmonary complications.

Pulmonary blastoma is a rare malignant lung tumor with a poor prognosis. It is composed of immature mesenchymal and epithelial components that resemble fetal lung tissue. We aimed to share our treatment results in biphasic pulmonary blastoma. In Ataturk Chest Disease and Thoracic Surgery Center, five patients with biphasic pulmonary blastoma (four men, one woman, aged between 27 and 61-mean 39.4) were treated between 1987 and 2000 (0.3% of operated NSCC). Hemoptysis, cough, chest pain and dyspnea were the symptoms. Anemia and high erythrocyte sedimentation rate were determined in two patients. Radiological examinations revealed a mass in four patients and massive pleural effusion in one. None of the patients were diagnosed preoperatively and hence all patients underwent exploratory thoracotomy. Three lobectomy, one pneumonectomy and one wedge resection were performed. Histopathological examinations revealed biphasic pulmonary blastoma in all the patients. Pathological stagings were as follows: 1 patient in T1N0M0 and 1 patient in T2N0M0 (198 and 112 months survival, respectively), three patients in T2N1M0 (9,10,17 months survival). In follow up period, prostate carcinoma and rectum carcinoma were detected as second primary tumors in the patient in stage T2N0M0. In patients who have small size tumors without nodal involvement, long-term survival can be obtained with radical surgery; even in biphasic pulmonary blastomas. According to our limited experiences, N1 nodal involvement shows very poor prognosis.

Angiolipomas are a subgroup of lipomas and are rarely observed benign tumours in which mature fat tissue and angiomatous elements exist jointly. Costa-induced angiolipomas are rarer. A male patient aged 46 years consulted our clinic due to severe pain in his left side. The patient's X-ray showed a lobulated area with increased density (bone mass) in the left upper zone of the lung. A lesion in the fourth rib was excised with a left thoracotomy. Pathological diagnosis was reported as angiolipoma.
RESUMEN
Neurothekeoma, also known as nerve sheath myxoma, is a benign nerve sheath tumor that usually arises in the cutaneous nerves of the head, neck, or upper extremities. Extracutaneous placement is very rare. Mediastinal neurothekeoma has not previously been reported in the English literature. A 30-year-old woman was admitted to our clinic with back pain. A smooth-edged mass found in her paravertebral region, and a neurogenic tumor was suspected. The tumor was completely excised. Final pathology revealed it to be a mediastinal neurothekeoma.

Tracheal bronchus is a rare congenital anomaly of the bronchial tree, in which an aberrant bronchus originates in the trachea anywhere above the carina, but usually within 2 cm of it. Lung neoplasms that develop from tracheal bronchus have been identified only rarely. We present a case of tracheal bronchus that included a malignancy of the affected right upper lobe. The post-surgical histological stage was T4N0M0 stage IIIA. The patient was in good condition 24 months after the operation, and there was no evidence of recurrence. Before 2012, 14 cases of lung cancer that developed from tracheal bronchus had been reported.

OBJECTIVE: Given its importance in trauma practice, we aimed to determine the pathologies associated with blunt chest injuries and to analyze the accurate identification of patients at high risk for major chest trauma. METHODS: We reviewed our experience with 1490 patients with blunt chest injuries who were admitted over a 2-year period. Patients were divided into three groups based on the presence of rib fractures. The groups were evaluated to demonstrate the relationship between the number of rib fractures and associated injuries. The possible effects of age and Injury Severity Score (ISS) on mortality were analyzed. RESULTS: Mean hospitalization time was 4.5 days. Mortality rate was 1% for the patients with blunt chest trauma, 4.7% in patients with more than two rib fractures and 17% for those with flail chest. There was significant association between the mortality rate and number of rib fractures, the patient's age and ISS. The rate of development of pneumothorax and/or hemothorax was 6.7% in patients with no rib fracture, 24.9% in patients with one or two rib fractures and 81.4% in patients with more than two rib fractures. The number of rib fractures was significantly related with the presence of hemothorax or pneumothorax. CONCLUSION: Achieving better results in the treatment of patients with chest wall injury depend on a variety of factors. The risk of mortality was associated with the presence of more than two rib fractures, with patients over the age of 60 years and with an ISS greater than or equal to 16 in chest trauma. Those patients at high risk for morbidity and mortality and the suitable approach methods for them should be acknowledged.

A 51-year-old man with adenoid cystic carcinoma in the main stem bronchus was treated by a left lower lobectomy. A 44-year-old man with adenoid cystic carcinoma in the peripheral small bronchi underwent a right sleeve upper lobectomy with tracheobronchoplasty and neo-carina reconstruction; because of positive tumor margins, radiotherapy was administered postoperatively. Both patients were alive without any signs of tumor after 30 and 24 months of follow-up, respectively.
