RESUMEN
PURPOSE: In recent years, the use of fluorodeoxyglucose PET-computed tomography (PET-CT) has become widespread to evaluate the diagnosis, metabolism, stage and distant metastases of thymoma. In this study, it was aimed to investigate the connection of malignancy potential, survival and maximum standardized uptake value (SUV max ) measured by PET-CT before surgery according to the histological classification of the WHO in patients operated for thymoma. In addition, the predictive value of the Glasgow prognostic score (GPS) generated by C-reactive protein (CRP) and albumin values on recurrence and survival was investigated and its potential as a prognostic biomarker was evaluated. METHODS: Forty-five patients who underwent surgical resection for thymoma and were examined with PET-CT in the preoperative period between January 2010 and January 2022 were included in the study. The relationship between WHO histological classification, tumor size and SUV max values on PET-CT according to TNM classification of retrospectively analyzed corticoafferents were evaluated. Preoperative albumin and CRP values were used to determine GPS. RESULTS: The cutoff value for SUV max was found to be 5.65 in the patients and the overall survival rate of low-risk (<5.65) and high-risk (>5.65) patients was compared according to the SUV max threshold value (5.65) and found to be statistically significant. In addition, the power of PET/CT SUV max value to predict mortality (according to receiver operating characteristics analysis) was statistically significant ( P â =â 0.048). Survival expectancy was 127.6 months in patients with mild GPS (O points), 96.7 months in patients with moderate GPS (1 point), and 25.9 months in patients with severe GPS (2 points). CONCLUSION: PET/CT SUV max values can be used to predict histological sub-type in thymoma patients, and preoperative SUV max and GPS are parameters that can provide information about survival times and mortality in thymoma patients.

Tumor markers are indicators that can be used not only for cancer diagnosis but also for determining prognosis. Unfortunately, there is currently no tumor marker that reliably predicts the prognosis of lung cancer. In this study, we investigated the prognostic impact of the platelet-to-lymphocyte ratio (PLR) and Glasgow Prognostic Score (GPS), known as inflammation markers in peripheral blood, in patients who underwent resection for early-stage non-small cell lung cancer (NSCLC). We retrospectively analyzed the medical records of a total of 3300 patients who underwent surgery for NSCLC between 2010 and 2020. Among these patients, 250 met the inclusion criteria of lobectomy, pT1-T2N0 stage, and histology of adenocarcinoma or squamous cell carcinoma. Preoperative albumin, C-reactive protein (CRP), preoperative PLR, and postoperative 5th-day PLR values were determined from patient's peripheral blood data. The impact of these values on postoperative recurrence and survival was investigated. GPS was calculated based on preoperative CRP and albumin values, and patients were divided into 3 groups: 0 (mild), 1 (moderate), and 2 (severe). The relationship between preoperative GPS and survival was analysed. Among the included patients, 155 (62%) had adenocarcinoma and 95 (38%) had squamous cell carcinoma. A total of 185 (74%) patients had pT1 tumors, while 65 (26%) had pT2 tumors. During the postoperative follow-up period, local recurrence was observed in 28 (11.2%) patients and distant metastasis in 51 (20.4%) patients. The overall mortality rate was 19.6%. The 5-year survival rates for pT1 and pT2 tumors were 80.4% and 72.5%, respectively. Significant associations were found between preoperative PLR, postoperative PLR, and recurrence (p = 0.005 and p = 0.011). The expected overall survival (OS) was 103.4 months in the mild GPS group, 91.8 months in the moderate GPS group, and 50 months in the severe GPS group. The relationship between GPS groups and OS was statistically significant (p = 0.005). Preoperative analysis of PLR and GPS may provide prognostic value in NSCLC patients who undergo surgical resection. Our study provides a rationale for further investigation of peripheral blood immune markers for prognostic purposes.

Controversy still exists regarding the staging of non-small cell lung cancer (NSCLC) with adjacent lobe invasion (T-ALI) according to the TNM system in terms of T factor and the appropriate surgical resection method. We performed an analysis to compare the prognosis of T-ALI with T2 and T3 disease and to see the effect of our surgical method for these tumors. Two hundred consecutive patients between January 2012 and November 2020, with anatomical lobectomy for T2 or T3 tumor (Group-1) and non-anatomical lobectomy resection (lobectomy plus wedge resection [LWR]) (Group-2) for T-ALI (T2-ALI and T3-ALI) due to primary NSCLC, who did not have lymph node metastases were analyzed retrospectively. All surgeries were performed by two experienced surgeons who adopted the same surgical technique. Those who underwent additional segmentectomy and bilobectomy due to fissure invasion were excluded from the study. Overall survival rates of all patients were determined and factors affecting survival were evaluated by performing univariate and multivariate analyses. Of the patients with a mean age of 62.2 ± 7.8 years, 175 (87.5%) were male and 25 (12.5%) were female. There were 137 (68.5%) patients in Group 1 and 63 (31.5%) patients in Group 2. The mean tumor size in Group 1 (4.4 ± 1.4 cm) was significantly smaller than that in Group 2 (4.9 ± 1.4 cm) (p = 0.014). When T distribution within the groups was considered, the rate of pathological T3 in Group 1 (33.6%) was significantly lower than that in Group 2 (55.6%) (p = 0.005). While the 5-year overall survival rate was 70.1% in Group 1, it was 50.6% in Group 2 (p = 0.022). When tumors were grouped as T2, T2-ALI, T3, and T3-ALI according to T factor, the 5-year overall survival rates were 71.4% and 67.8% in T2 and T3 tumors, respectively, and 49.2% and 51.5% in T2-ALI and T3-ALI tumors, respectively. In the multivariate analysis of these four groups, the overall survival rates for T2-ALI and T3-ALI were significantly lower than those of T2 tumors (p = 0.046 and p = 0.025, respectively). In the analysis made between the T2 tumor group and the new T3 group (T2-ALI, T3, T3-ALI), which was formed by upgrading T2-ALI tumors to the T3 group, T2 tumors were found to have a significantly better survival rate (p = 0.019). The disease-free survival of pT2 patients and new T3 group patients was statistically significant, 63.7% and 45.7%, respectively (p = 0.050). Our results suggest that LWR for T-ALI can be performed with acceptable oncologic outcomes when compared to anatomical lobectomy. T2-ALI has a worse overall survival than T2 tumor and offers a similar prognosis to T3. Given this situation, it is more appropriate to classify T2-ALI as T3. Further studies based on larger series are needed to confirm these preliminary data.

Introduction: The purpose of this study is to determine how long patients who developed pneumothorax were followed up on in the emergency department, how many patients required chest tube placement, and what factors influenced the need for a chest tube in patients who underwent computed tomography (CT)-guided percutaneous transthoracic fine needle aspiration biopsy (PTFNAB). Materials and Methods: Patients who developed pneumothorax following CT-guided PTFNAB were analyzed retrospectively. In cases with pneumothorax, the relationship between chest tube placement and the size of the lesion, the lesion depth from the pleural surface, the presence of emphysema, and the needle entry angle were investigated. It was determined how long the patients were followed up in the emergency department, when a chest tube was placed, and when patients who did not require chest tube placement were discharged. Result: CT-guided PTFNAB was performed in 3426 patients within two years. Pneumothorax developed in 314 (9%) cases and a chest tube was placed in 117 (37%). The risk factor for chest tube placement was found to be the lesion depth from the pleural surface. The lesion depth from the pleural surface of >24 mm increased the risk of chest tube placement by 4.8 times. Chest tubes were placed at an average of five hours (5.04 ± 5.57). Conclusions: This study has shown that in cases with pneumothorax that required chest tube placement, the lesion depth from the pleural surface is a risk factor. Patients who developed pneumothorax on CT during the procedure had chest tubes placed after an average of five hours.

Nodal metastasis status is an important parameter affecting the prognosis in lung cancer. Although surgical treatment is possible in most cases of N1 positive non-small cell lung cancer, this group of patients is clinically, radiologically and histologically heterogeneous. The aim of our study is to investigate the prognostic factors affecting survival in patients with pT1-2 N1 who underwent lung resection. From January 2010 to December 2019, patients who underwent lobectomy, bilobectomy or pneumonectomy for pT1-T2 N1 NSCLC in our center were included in the study. The preoperative, intraoperative and postoperative data of the patients were recorded by accessing the patient files and hospital records. The mean follow-up time was 39.8 months. The mean overall survival was 73.8 ± 3.6, and the mean disease-free survival was 67.5 ± 3.8. In multivariate analysis, age, N1 nodal metastasis pattern (occult vs obvious) and histology were found as independent variables affecting survival. In our study, age, histology, and clinical N1 status were found to be independent variables effective on overall survival.

BACKGROUND: We conducted this study to investigate the need for dissection of station 9 lymph nodes during upper lobectomy for non-small-cell lung cancer (NSCLC) and to find out the operative results of inferior pulmonary ligament division. METHODS: A total of 840 patients who underwent upper lobectomy for NSCLC between January 2007 and June 2020 were evaluated retrospectively. The patients were separated into two groups - those having undergone lymph node dissection of station 9 and inferior pulmonary ligament dissection (Group I) and those who did not (Group II). In these groups, the prognostic value of station 9 lymph nodes and postoperative effects (drainage time, prolonged air leak, dead space and length of hospital stay) of ligament division or preservation were analyzed. RESULTS: The number of patients with station 9 lymph node metastasis was only one (0.1%) and that was multi-station pN2 disease. Station 9 lymph nodes were found in 675 (80.4%) patients, while 22 (2.6%) patients had no lymph nodes in the dissected material. In the other 143 (17%) patients, the inferior pulmonary ligament and station 9 were not dissected. While 5-year survival was 64.9% in 697 patients of Group I, it was 61.3% in 143 patients of Group II (p = 0.56). There was no statistically significant difference between the groups in postoperative effects of ligament division or preservation. CONCLUSIONS: In upper lobectomies, status of station 9 does not have a significant impact on patients' survival and lymph node staging. Additionally, preservation or division of the inferior pulmonary ligament has no significant advantage or disadvantage.

Background: In this study, we aimed to examine the effectiveness of pulmonary rehabilitation applied after resection in patients with lung cancer. Methods: Between October 2017 and December 2019, a total of 66 patients (53 males, 13 females; median age: 65 years; range, 58 to 70 years) who underwent lung resection for non-small cell lung cancer and who were not administered any chemotherapy or radiotherapy regimen were included in the study. An eight-week comprehensive outpatient pulmonary rehabilitation program was applied to half of the patients, while the other half received respiratory exercise training. After the intervention, the results of both groups were compared. Results: In the pulmonary rehabilitation group, forced vital capacity value (p=0.011), six-minute walking distance (p<0.001), and Short Form-36 physical function, mental health, vitality scores increased significantly, while all scores of St. George's Respiratory Questionnaire, dyspnea (p<0.001) and anxiety score (p=0.041) significantly decreased. In the group given breathing exercise training, only dyspnea (p=0.046) and St. George's Respiratory Questionnaire symptom scores (p=0.038) were decreased. When the changes in the groups after pulmonary rehabilitation were compared, the decrease in dyspnea perception was significantly higher in the pulmonary rehabilitation group (p<0.001). Conclusion: Pulmonary rehabilitation program applied after lung resection in patients with non-small cell lung cancer reduces dyspnea and psychological symptoms, increases exercise capacity, and improves quality of life. It should be ensured that patients with lung cancer who have undergone lung resection are directed to the pulmonary rehabilitation program and benefit from this program.
RESUMEN
PURPOSE: Pulmonary hydatid cyst (PHC) can imitate many diseases. Sometimes, positron emission tomography/computed tomography (PET/CT) is performed in terms of malignancy exclusion for complicated cysts. Although some specific findings (doughnut sign) have been identified in hydatid cyst of the liver, there is no specific sign described for PHC. The aim of this study is to investigate the presence of a common finding in PHC patients scanned with PET/CT inadvertently. MATERIALS AND METHODS: From January 2015 to 2020, patients proven to have PHC were analyzed retrospectively. From all the patients, only 17, having a previous PET/CT, were included the study. Lesions were evaluated in three groups according to FDG uptake: A, negative; B, focal; C, doughnut sign. RESULTS: The total number of patients was 17. Nine of the patients were male and the median age was 41.94 + 14.68 (16-65) years. SUV max of the lesions ranged from 0.5 to 15.8 (mean ± SE: 4.68). According to the FDG uptake of the lesions, five were in Group A, two in Group B, and the remaining ten (58.8%) in Group C with doughnut sign. To correlate the CT findings with PET/CT findings, doughnut sign, which is a typical finding of hydatid cysts of liver, is seen in only four patients in Group 1-classified cysts which are non-complicated. But in Group 2 (n = 3) and 3(n = 4), the finding of doughnut sign is three in both groups. CONCLUSIONS: PET/CT is not a recommended imaging technique for PHC, but in cases where a definitive diagnosis is difficult, interpreting PET/CT findings is significant. This study demonstrates that previously described doughnut sign for liver hydatid cysts is also common for perforated pulmonary cysts. According to our knowledge, this is the first largest series of determining PET/CT findings of PHC. Further larger series will contribute to the literature.

Background: In this study, we aimed to evaluate patients who had non-small cell lung cancer and underwent resection, to investigate our tendency to prefer video-assisted thoracic surgery or open thoracotomy, and to compare 30- and 90-day mortalities and survival rates. Methods: Between January 2013 and January 2019, a total of 706 patients (577 males, 129 females; mean age: 61.9±8.6 years; range, 17 to 84 years) who underwent lobectomy or bilobectomy due to primary non-small cell lung cancer were retrospectively analyzed. The patients were divided into two groups as operated on through video-assisted thoracic surgery and through open thoracotomy. The 30- and 90-day mortality rates and survival rates were compared. Results: Of the patients, 202 (28.6%) underwent video-assisted thoracic surgery and 504 (71.4%) underwent open thoracotomy. Lobectomy was performed in 632 patients (89.5%) and bilobectomy was performed in 74 patients (10.5%). Patients who were chosen for video-assisted thoracic surgery were statistically significantly older, did not require any procedure other than lobectomy, did not receive neoadjuvant therapy, had a small tumor, and did not have lymph node metastases. The 30- and 90-day mortality rates in the video-assisted thoracic surgery and open thoracotomy groups were 1.8% vs. 2% and 2.6% vs. 2.5%, respectively. The five-year survival rates of video-assisted thoracic surgery and open thoracotomy groups were 74.1% and 65.2%, respectively (p>0.05). The 30- and 90-day mortality and five-year survival rates were 2.1%, 2.6%, and 73.5% in the video-assisted thoracic surgery group and 2.1%, 2.1%, and 68.5% in the open thoracotomy group, respectively, indicating no statistically significant difference between the two groups. Conclusion: Throughout the study period, video-assisted thoracic surgery was more preferred in patients with advanced age, in those who had a small tumor, who did not receive neoadjuvant therapy, did not have lymph node metastasis, and did not require any procedure other than lobectomy. In the video-assisted thoracic surgery and open thoracotomy groups, 30- and 90-day mortality and five-year survival rates were similar. Based on these findings, both procedures seem to be acceptable in this patient population.
RESUMEN
INTRODUCTION: The mortality of massive hemoptysis is high, and it is important to make quick decisions. Emergency pulmonary resection continues to be a mandatory option when conservative methods cannot prevent massive hemoptysis, as it is life-threatening. AIM: We report our experience with patients undergoing pulmonary resection for massive hemoptysis. MATERIAL AND METHODS: This study is a retrospective analysis of 39 consecutive patients who were referred to the thoracic surgery intensive care unit of a tertiary hospital for massive hemoptysis and underwent emergency pulmonary resection by thoracotomy between January 2007 and March 2021. RESULTS: Male dominance with an average age of 49.3 (16-70) and a gender ratio of 3.3 were recorded. The most common underlying cause of massive hemoptysis was bronchiectasis (n = 16). Bronchiectasis was followed by aspergilloma (n = 11) and previous tuberculosis (n = 8). Bronchial artery embolization was performed in 20.5% of patients. Twenty-nine (74.4%) lobectomies, 7 (17.9%) pneumonectomies, and 3 (7.7%) segmentectomies were performed. The mean operation duration was 253.6 ±71 minutes. Recurrent hemoptysis was recorded in 7.7% of patients. Postoperative life-threatening complications were seen in 28.2%, while minor complications developed in 28.2% of patients. Postoperative complications were significantly higher in patients with tuberculosis sequelae (p = 0.006). Hospital mortality was observed in 5.1% of patients. CONCLUSIONS: The postoperative period is more problematic in patients with a history of tuberculosis who undergo emergency pulmonary resection due to massive hemoptysis. Despite this, emergency pulmonary resection is a curative method with acceptable postoperative complications and low hospital mortality in all tolerant patients according to their clinical condition.
RESUMEN
INTRODUCTION: We reviewed our surgical preferences and the prognosis for recurrent and second primary tumors in patients who underwent surgical treatment for non-small cell lung carcinoma (NSCLC). AIM: We report our experience with patients undergoing iterative pulmonary resection for lung cancer. MATERIAL AND METHODS: Among patients who underwent anatomical resection for primary NSCLC, those who underwent a second surgical resection between 2010 and 2020 due to recurrent or second primary tumor were included in the study. Operative mortality, survival, and prognostic factors were investigated. RESULTS: In total, 77 cases were included: 31 (40.3%) underwent the second resection for the recurrent disease and 46 (59.7%) underwent the second resection for the second primary tumor. Postoperative mortality occurred in 8 (10.4%) patients. All patients with postoperative mortality were in the group that underwent thoracotomy in both surgical procedures. The 5-year survival rate was 46.5%. The 5-year survival of those operated on for recurrent or second primary tumor was 32.8% and 51.1%, respectively (p = 0.81). The 5-year survival rate was 68.8% in patients under the age of 60 years, while it was 27.5% in patients aged 60 years and above (p = 0.004). The 5-year survival was 21.8% in patients with an interval of 36 months or less between two operations and 72.2% in those with a longer interval (p = 0.028). CONCLUSIONS: Our study shows that survival results similar to or better than primary NSCLC surgery can be obtained with lower mortality if more limited resections are performed via video-assisted thoracic surgery, especially in young patients. In addition, the prognosis is better in patients with an interval of more than 36 months between two operations.
RESUMEN
BACKGROUND: Lung cancer surgery may be required for patients with a history of coronary artery bypass graft (CABG). In this study, we evaluated the general characteristics of patients, the difficulties experienced during and after lung cancer surgery and complications and mortality rates. METHOD: Patients who were operated on for primary lung cancer between January 2012 and July 2017 in the participating centres were analysed retrospectively (n=7,530). Patients with a history of CABG (n=220) were examined in detail. This special group was analysed and compared with other patients operated on for lung cancer who did not have CABG (n=7,310) in terms of 30-day mortality and revision for haemorrhage. RESULTS: Of the 7,530 patients operated on for primary lung cancer, 2.9% were found to have undergone CABG. Surgical revision was required in the early postoperative period for 6.8% of those who had CABG and 3.5% in those who did not have CABG (p=0.009). Thirty-day (30-day) mortality was 4.5% in those who had CABG and 2.9% in those who did not have CABG (p=0.143). Further analysis of patients who had undergone CABG demonstrated that video-assisted thoracoscopic surgery (VATS) resulted in fewer complications (p=0.015). Patients with a left-sided left internal mammary artery (LIMA) graft had a higher number of postoperative complications (p=0.30). CONCLUSIONS: Patients who had CABG suffered postoperative haemorrhage requiring a revision twice as often, and a tendency towards higher mortality (non-statistically significant). In patients with a history of CABG, VATS was demonstrated to have fewer complications. Patients with a LIMA graft who had a left-sided resection had more postoperative complications.

BACKGROUND: Video-assisted mediastinoscopy (VAM) is a valuable method in the investigation of diseases with mediastinal lymphadenopathy or those localized in the mediastinum. The aim of this study was to determine the diagnostic value of VAM in the investigation of mediastinal involvement of nonlung cancer diseases and to describe our institutional surgical experience. METHODS: Clinical parameters such as age, sex, histological diagnosis, morbidity, and mortality of all patients who underwent VAM for the investigation of mediastinal involvement of diseases except lung cancer between January 2006 and July 2018 were retrospectively reviewed, and the diagnostic efficacy of VAM was determined statistically. RESULTS: During the study period, 388 patients underwent VAM, and 536 lymph nodes were sampled for histopathological evaluation of mediastinum due to mediastinal lymphadenopathy or paratracheal lesions. The most common diagnoses were sarcoidosis (n = 178 [45.9%]), tuberculous lymphadenitis (n = 108 [27.8%]), lymphadenitis with anthracosis (n = 72 [18.6%]), and lymphoma (n = 15 [3.9%]). CONCLUSION: The results of the study show that VAM should be used because of its high diagnostic benefit in mediastinal lymphadenopathies, which are difficult to diagnose, or mediastinal lesions located in the paratracheal region. Despite the increase in the number of new diagnostic modalities, VAM is still the most effective method and a gold standard.

OBJECTIVES: Severe acute respiratory syndrome coronavirus 2, a novel coronavirus, affects mainly the pulmonary parenchyma and produces significant morbidity and mortality. During the pandemic, several complications have been shown to be associated with coronavirus disease 2019 (COVID-19). Our goal was to present a series of patients with COVID-19 who underwent chest tube placements due to the development of pleural complications and to make suggestions for the insertion and follow-up management of the chest tube. METHODS: We retrospectively collected and analysed data on patients with laboratory-confirmed COVID-19 in our hospital between 11 March and 15 May 2020. Patients from this patient group who developed pleural complications requiring chest tube insertion were included in the study. RESULTS: A total of 542 patients who were suspected of having COVID-19 were hospitalized. The presence of severe acute respiratory syndrome coronavirus 2 was confirmed with laboratory tests in 342 patients between 11 March and 15 May 2020 in our centre. A chest tube was used in 13 (3.8%) of these patients. A high-efficiency particulate air filter mounted double-bottle technique was used to prevent viral transmission. CONCLUSIONS: In patients with COVID-19, the chest tube can be applied in cases with disease or treatment-related pleural complications. Our case series comprised a small group of patients, which is one of its limitations. Still, our main goal was to present our experience with patients with pleural complications and describe a new drainage technique to prevent viral transmission during chest tube application and follow-up.

OBJECTIVES: Nonsmall cell lung cancer (NSCLC) is a multifactorial disease, and differences in the characteristics of surgical patients may develop over the years. This study aimed to evaluate the patients who underwent curative surgical resection for NSCLC in the past 20 years at our center and analyze the changes in the treatment strategies based on demographics, surgical strategies, and histopathology. MATERIALS AND METHODS: In this retrospective single-center cohort study, 1995 patients who had undergone lobectomy, bilobectomy, or pneumonectomy for primary NSCLC from January 1997 to January 2017 were analyzed. Patients were divided into two groups: Group I included patients operated in the first 10 years and Group II included patients operated in the last 10 years. RESULTS: Overall, 77% of patients were operated in the last 10 years (458 vs. 1537 patients). Sleeve lobectomies performed in Group II reduced the rate of pneumonectomy from 37% to 20% (p<0.001). The operation rates for adenocarcinomas increased significantly during the study period, increasing from 31.4% to 36.2% (p=0.049). The 30- and 90-day postoperative mortality rates were 4.6% and 8.5% in Group I and 4.1% and 5.7% in Group II, respectively (p=0.69 and p=0.037, respectively). When the groups were compared, the median and 5-year survival rates were 44.1 months (95% confidence interval [CI], 35.6-52.6) and 42.9% in Group I and 73.6 months (95% CI, 63.3-83.9) and 53.9% in Group II, respectively (p<0.001). CONCLUSION: This study demonstrates an improvement in long-term outcomes following lung cancer surgery with an increasing rate of surgical procedures in the last 10 years. There was an increase in the proportion of females affected and the rate of adenocarcinoma. However, the pneumonectomy and postoperative N2 disease rates have decreased with advancing preoperative evaluation techniques and parenchyma-saving surgical methods. Postoperative mortality has decreased, and the survival rate has increased.
RESUMEN
BACKGROUND: Ipsilateral pulmonary metastasis (PM) in the same lobe (T3Satell) or different lobe (T4Ipsi Nod) constitutes a small proportion of patients with non-small cell lung cancer (NSCLC). In our study, we aimed to determine prognostic factors and to evaluate long-term survival outcomes in the patients who underwent complete resection due to NSCLC. METHODS: Data of 1,502 surgically treated patients with NSCLC from January 2007 to December 2016 were retrospectively reviewed. Fifty (3.3%) patients diagnosed with PM were the basis of the study. Demographic and histopathological characteristics, surgical procedures, and prognostic factors for survival were analyzed, categorizing patients according to the presence of PM in the same lobe or different lobe. RESULTS: Among the 50 patients, 23 (46%) had PM in the same lobe as the primary tumor and 27 (54%) had PM in different ipsilateral lobes. The mean size of nodules was 11.5 mm. While T3Satell was detected mostly in squamous cell carcinoma (SCC) (65.2%), T4Ipsi Nod was more common in adenocarcinoma (AC) (70.4%), and the difference was statistically significant (p = 0.022). Survival was significantly better in the SCC-T3Satell group than the AC-T3Satell group (64 and 58.3%, respectively; p = 0.043). Although the overall 5-year survival was better in the T3Satell group, the difference between survival outcomes of both groups was not statistically significant (61.2 and 37.2%, respectively; p = 0.27). In the T3Satell group, nodule size was found to be a negative prognostic factor in survival (p = 0.042), whereas the number of nodules was found to be a negative prognostic factor in the T4Ipsi Nod group (p = 0.046). In multivariate analysis, advanced age was a poor prognostic factor for PM (p = 0.03). CONCLUSION: There was no significant difference in survival between T3Satell and T4Ipsi Nod patients. Among surgically treated patients due to NSCLC, poor prognostic factors were advanced age for the patients with PM, nodule size and AC for T3Satell patients, and the number of nodules for T4Ipsi Nod patients.

OBJECTIVES: Pathological N2 (pN2) involvement has a negative impact on prognosis in patients operated on due to non-small-cell lung cancer (NSCLC). pN2 disease may cause skip (pN0N2) or non-skip (pN1N2) metastases with pathological N1 (pN1) involvement. The effect of pN2 subgroups on prognosis is still controversial. We analysed the effect of pN1 disease and single-station pN2 disease subgroups on survival outcomes. METHODS: The medical records of patients who underwent anatomical lung resection due to NSCLC at a single centre between January 2007 and January 2017 were prospectively collected and retrospectively analysed. Operative mortality, sublobar resection, Stage IV disease, incomplete resection and carcinoid tumour were considered exclusion criteria. After histopathological examination, the prognosis of patients with pN1, pN0N2 and pN1N2 was compared statistically. Univariable and multivariable analyses were made to define independent risk factors for overall survival rates. RESULTS: The mean follow-up time for 358 patients with 228 pN1 disease (63.7%), 59 pN0N2 disease (16.5%) and 71 pN1N2 disease (19.8%) was 40.4 ± 30.4 months. Median and 5-year overall survival rates for pN1, pN0N2 and pN1N2 diseases were 73.6 months [95% confidence interval (CI) 55.5-91.7] and 54.1%, 60.3 months (95% CI 26.8-93.8) and 51.2%, 20.8 months (95% CI 16.1-25.5) and 21.5%, respectively. The survival CIs of pN1 and pN0N2 diseases were similar, and the survival rates of these 2 groups were significantly better than those with pN1N2 (P < 0.001, P = 0.001, respectively). In multivariable analysis, patients over the age of 60 [hazard ratio (HR) 2.13, P < 0.001], patients not receiving adjuvant therapy (HR 1.52, P = 0.01) and patients with pN1N2 disease (HR 2.91, P < 0.001) had a poor prognosis. CONCLUSIONS: Advanced age, not receiving adjuvant therapy and having pN1N2 disease are negative prognostic factors in patients with nodal involvement who underwent curative resection due to NSCLC. The overall survival and recurrence-free survival rates of pN1 disease and single-station pN0N2 disease are similar, and they have significantly better survival rates than pN1N2 disease. Based on these results, surgical treatment may be considered an appropriate choice in patients with histopathologically diagnosed single-station skip-N2 disease.

BACKGROUND: This study aims to investigate the operation-related complications, recurrence frequency, morbidity, mortality and survival rates as well as variables effective on survival of patients undergoing bronchial sleeve lobectomy due to primary non-small cell lung cancer. METHODS: A total of 85 patients ( 80 males, 5 females; mean age 59.9±8.4 years; range, 35 to 77 years) of bronchial sleeve lobectomy operated with the same surgical technique by the same team in our clinic between May 2007 and November 2015 were analyzed retrospectively. Survival and 30- and 90-day mortality rates were analyzed. Variables effective on survival rate were evaluated statistically. Complications related to bronchial anastomosis and the frequency of local recurrence in postoperative period were investigated. RESULTS: Twenty-five patients (29.4%) received neoadjuvant therapy and two of these patients (8%) developed complication in the anastomosis line. Local recurrence rate in the postoperative follow-up was 16.5%. Mean duration of follow-up was 35±29.9 months, median survival was 65.2 months, and five-year survival rate was 50.9%. Thirty- and 90-day mortality rates were 1.2% and 2.4%, respectively. In univariate analysis, patients with larger tumors, N2 disease, or those who underwent extended surgery had statistically significantly worse survival rates (p=0.001, p=0.002, and p=0.0001, respectively). In the Cox regression analysis, variables effective on survival were presence of extended surgery and node status (p=0.03 and p=0.012, respectively). CONCLUSION: Sleeve lobectomy can be achieved with acceptable anastomotic complications, good survival and low mortality rates using continuous suture technique. When performed due to oncological reasons, its long-term results are not different from pneumonectomy.
RESUMEN
Herein, we describe the case of a 67-year-old female patient who presented with cough and haemoptysis. Chest computed tomography revealed destruction of the left lower lobe and multiple fungus balls in a bronchiectatic cavity. A left lower lobectomy was performed via thoracotomy. Histopathological examination of the lung showed a concomitant aspergilloma and multiple tumourlets in the large bronchiectatic cavity. Pulmonary intracavitary aspergilloma and concomitant tumourlets are quite rare. Our report presents this interesting case that manifested with haemoptysis.
RESUMEN
PURPOSE: Bronchopleural fistula (BPF) is a catastrophic complication after pneumonectomy, still associated with high mortality. We reviewed our recent experience of managing BPF, particularly after right pneumonectomy for non-small cell lung cancer (NSCLC), and analyzed our findings. METHODS: A total of 436 patients underwent pneumonectomy for NSCLC in our department between January 2000 and June 2017. BPF developed during follow-up in 47 of these patients, who are the subjects of this retrospective analysis. RESULTS: The overall incidence of BPF was 10.8% (47/436), being 22.8% (33/145) after right pneumonectomy and 4.8% (14/291) after left pneumonectomy (P = 0.0001). The incidence of BPF in patients with a history of tuberculosis was 33.3% (6/18; P = 0.008). The fistula healed in 48.9% (23/47) of the patients and the rate of mortality caused by the fistula was 19.1% (9/47). CONCLUSIONS: The side of the pneumonectomy and previous tuberculosis were the two most important risk factors independent of the bronchial closure methods. The incidence of BPF was much higher after right pneumonectomy than after left pneumonectomy. The high mortality and morbidity rates show that the treatment of BPF is still not satisfactory.
