ABSTRACT

BACKGROUND: This study evaluated the prevalence and quantity of lymph nodes at particular stations of the mediastinum in patients with lung cancer. These data are important to radiologists, pathologists, and thoracic surgeons because they can serve as a benchmark when assessing the completeness of lymph node dissection. However, relevant data in the literature are scarce. METHODS: Data regarding the number of lymph nodes derived from two randomised trials of bilateral mediastinal lymph node dissection, the BML-1 and BML-2 study, were included in this analysis. Detectable nodes at particular stations of the mediastinum and the number of nodes at these stations were analysed. RESULTS: The mean number of removed nodes was 28.67 (range, 4-88). Detectable lymph nodes were present at stations 2R, 4R, and 7 in 93%, 98%, and 99% of patients, respectively. Nodes were rarely present at stations 9 L (33%), and 3 (35%). The largest number of nodes was observed at stations 7 and 4R (mean, 5 nodes). CONCLUSION: The number of mediastinal lymph nodes in patients with lung cancer may be greater than that in healthy individuals. Lymph nodes were observed at stations 2R, 4R, and 7 in more than 90% of patients with lung cancer. The largest number of nodes was observed at stations 4R and 7. Detectable nodes were rarely observed at stations 3 and 9 L. TRIAL REGISTRATION: ISRCTN 86,637,908.

ABSTRACT

Background: Positron-emission tomography (PET) is widely used for staging lung cancer. Although a correlation between the fluorodeoxyglucose standardized uptake value (SUV) and the histologic grade of the tumor has been shown in several studies, little is known about the impact of different clinical variables on this correlation. This study aimed to evaluate the correlation between tumor SUV and tumor grade in a large cohort of patients and to analyse the impact of clinical factors on this correlation. Methods: This retrospective cohort study including patients with non-small cell lung cancer age 18-90 years, with clinical stage I-IVA, who underwent curative-intent lung resection. Results: Data from 726 patients was included in this study. There was a strong correlation between SUV and primary tumor grade in the whole cohort (P<0.001), which was significant in both sexes (P<0.001) and in all selected age groups (P<0.001-0.03). There was a significant SUV-grade correlation for the right upper and left lower lobes, as well as for the central location in the right lung (P<0.001, P=0.005 and P=0.04, respectively). Moreover, a significant SUV-grade correlation was found for squamous cell cancer and adenocarcinoma (P<0.001 and P=0.01, respectively), and for T1-T3 factors (P<0.001, P=0.006, P=0.005 respectively). Conclusions: In patients with resectable lung cancer, a significant correlation was observed between the SUV of the primary tumor and its grade. This correlation was maintained for both sexes, age groups, most common histological types and T factors T1-T3.

ABSTRACT

BACKGROUND: Primary melanoma of the esophagus (PME) represents a rare type of gastrointestinal malignancy with an exceptionally poor diagnosis. So far, only few descriptions of PME which satisfactorily summarize their clinical characteristics and prognosis have been published. OBJECTIVES: The aim of our study was to summarize our experience with PME patients. MATERIAL AND METHODS: In a group of 1387 patients who underwent esophagectomy due to neoplastic process in the years 2000-2020 in 2 high-volume university thoracic surgery centers, we identified those with confirmed PME diagnosis. Subsequently, their clinical characteristics, imaging and histopathological results were compared. The data regarding the long-term survival were obtained from the Polish National Death Registry. RESULTS: The PME was identified in 4 (0.29%) patients. Three of them (75%) were males. The mean age on admission was 64.3 ±17.5 years. The main symptom in all patients was dysphagia. In 1 patient with the most advanced PME, the clinically relevant weight loss was noted. In 3 patients, Ivor Lewis esophagectomy was performed, and 1 patient underwent McKeown resection. Histopathologic examination revealed a metastasis of lymph nodes only in 1 patient. The average maximum size of tumor was 6.9 ±4.7 cm and all tumors were located in distal part of the esophagus. Two out of those 4 patients are still alive and the longest survival time is 17 years. One patient died due to postoperative massive gastrointestinal bleeding complicated with cardiac arrest and the other one due to progression of PME systemic dissemination 6 months after surgical treatment. CONCLUSION: The PME is an extremely rare diagnosis. A long-term survival can be achieved with the complete resection. Clinical scenarios of surgically treated PME patients may significantly differ.

ABSTRACT

OBJECTIVES: This study aimed to analyze the effect of bilateral mediastinal lymphadenectomy (BML) on survival of non-small cell lung cancer (NSCLC) patients. The hypothesis was: BML offers survival benefit as compared with SLND. METHODS: A randomized clinical trial including stage I-IIIA NSCLC patients was performed. All patients underwent anatomical lung resection. BML was performed during the same operation via additional cervical incision (BML group). In the control group, standard lymphadenectomy (systematic lymph node dissection, SLND) was performed. RESULTS: In total, 102 patients were randomized. No significant difference was found in the type of lung resection, blood loss, chest tube output, air leak, pain, and complications (p = 0.188-0.959). In the BML group, the operative time was longer (318 vs 223 min, p < 0.001) with higher number of removed N2 nodes (24 vs 14, p < 0.001). The 5-year survival rate was 72 % in the BML group vs 53 % in the SLND group (OR 2.33, 95 % CI 0.95-5.69, p = 0.062). Separate comparisons for different lobar locations of the tumor have shown no significant difference in survival for the right lung tumors and left upper lobe tumors. For the left lower lobe tumors, survival time was longer in the BML group (p = 0.021), and the 5-year survival rate was 90.9 % vs 37.5 %, (OR 16.66, 95 % CI 1.36-204.04, p = 0.0277). CONCLUSIONS: In patients with NSCLC located in the left lower lobe, bilateral lymph node dissection may be associated with better survival. The invasiveness of BML is comparable to that of SLND.

ABSTRACT

BACKGROUND: No adjuvant treatment has been established for patients who remain at high risk for recurrence after neoadjuvant chemoradiotherapy and surgery for esophageal or gastroesophageal junction cancer. METHODS: We conducted CheckMate 577, a global, randomized, double-blind, placebo-controlled phase 3 trial to evaluate a checkpoint inhibitor as adjuvant therapy in patients with esophageal or gastroesophageal junction cancer. Adults with resected (R0) stage II or III esophageal or gastroesophageal junction cancer who had received neoadjuvant chemoradiotherapy and had residual pathological disease were randomly assigned in a 2:1 ratio to receive nivolumab (at a dose of 240 mg every 2 weeks for 16 weeks, followed by nivolumab at a dose of 480 mg every 4 weeks) or matching placebo. The maximum duration of the trial intervention period was 1 year. The primary end point was disease-free survival. RESULTS: The median follow-up was 24.4 months. Among the 532 patients who received nivolumab, the median disease-free survival was 22.4 months (95% confidence interval [CI], 16.6 to 34.0), as compared with 11.0 months (95% CI, 8.3 to 14.3) among the 262 patients who received placebo (hazard ratio for disease recurrence or death, 0.69; 96.4% CI, 0.56 to 0.86; P<0.001). Disease-free survival favored nivolumab across multiple prespecified subgroups. Grade 3 or 4 adverse events that were considered by the investigators to be related to the active drug or placebo occurred in 71 of 532 patients (13%) in the nivolumab group and 15 of 260 patients (6%) in the placebo group. The trial regimen was discontinued because of adverse events related to the active drug or placebo in 9% of the patients in the nivolumab group and 3% of those in the placebo group. CONCLUSIONS: Among patients with resected esophageal or gastroesophageal junction cancer who had received neoadjuvant chemoradiotherapy, disease-free survival was significantly longer among those who received nivolumab adjuvant therapy than among those who received placebo.

ABSTRACT

INTRODUCTION: Roux-en-Y gastric bypass (RYGB) and laparoscopic sleeve gastrectomy (LSG) are the two most frequently performed bariatric operations. These two types of metabolic surgery alter the anatomy and function of digestive tract producing significant weight loss in morbidly obese patients but may lead to malnutrition. AIM: Analysis of incidence and severity of malnutrition after bariatric surgery in patients submitted to RYGB or LSG during 12 months of follow-up. MATERIAL AND METHODS: Retrospective study of 98 patients after RYGB (n = 47) or LSG (n = 51) assessed for nutritional deficiencies during 12 months after surgery was conducted. The differences in body mass index (BMI) and blood tests including erythrocytes, haemoglobin, total protein, albumin, iron, ferritin, transferrin, vitamin B12, folic acid, calcium and phosphorus concentrations were compared between groups before the operations and at 1 and 12 months. RESULTS: Nutritional deficiencies were common before surgery with prevalence up to 19.6% for albumin in the LSG group. Median preoperative BMI levels and albumin concentrations were higher in the RYGB group compared to the LSG group, but there was no difference in percent excess weight loss (%EWL) at 1 and 12 months between LSG and RYGB. One month after LSG erythrocyte count, haemoglobin, iron, ferritin and transferrin levels were significantly higher than in the RYGB group. These differences subsided at 12 months. At 12 months, only the prevalence of vitamin B12 deficiency was significantly higher in the RYGB group. CONCLUSION: Both RYGB and LSG lead to nutritional deficiencies despite different properties of operations and similar %EWL during follow-up.

ABSTRACT

A diagnosis of pulmonary sarcoidosis is based on the assessment of clinical outcome, radiology findings and detection of noncaseating granulomas in cytology or histology specimens. Cytological material obtained from enlarged lymph nodes and/or histological specimens from bronchial mucosa and lung tissue are examined according to sarcoidosis stage. The most available are standard bronchoscopic methods as conventional transbronchial needle aspiration (cTBNA), endobronchial biopsy (EBB) and transbronchial lung biopsy (TBLB) both performed with use of forceps. The new endoscopic techniques introduced to pulmonary diagnostics are: endobronchial ultrasoundguided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) or if used by the ultrasound bronchoscope (EUS-b-FNA) and transbronchial lung cryobiopsy (TBLC). Considering a dynamic improvement in cytology assessment techniques (processed as cytology smears and cell blocks) the endoscopic methods with use of fine needle aspiration biopsy of enlarged lymph nodes became a method of choice in sarcoidosis with lymphadenopathy, and published data suggest a higher diagnostic yield when performed under endosonographic guidance. The optimal approach (transbronchial or transesophageal) and the selection of mediastinal lymph node stations considered for biopsy still need evaluation. Also TBLC, successfully used in the diagnosis of other diffuse parenchymal lung diseases, requires more experiences and trials to establish its role in diagnosis of pulmonary sarcoidosis.

ABSTRACT

INTRODUCTION: EBUS is a well established minimally invasive diagnostic tool for mediastinal and hilar lymphadenopathy. The novel ViziShot Flex 19G needle (Olympus Respiratory America, Redmond, WA, USA) was introduced in 2015 in order to improve loaded scope flexion and to obtain larger tissue samples for analysis. The aims of this study were to assess diagnostic yield of Flex 19G needles and to present endoscopist's feedback about the endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). MATERIAL AND METHODS: The Flex 19G needles were used in patients with hilar and/or mediastinal adenopathy in two Polish pulmonology centers. Cytology smears and cell blocks (CB) were prepared. The prospective analysis was performed due to collected data. RESULTS: Twenty two selected patients with confirmed adenopathy on chest-CT (mean age 58 ± 12) underwent EBUS-TBNA with use of Flex 19G needles. All procedures occurred to be diagnostic for smears (yield 100%). The malignancy was found in 15 cases (68.2%), and benign adenopathy in 7 (31.8%). In 12 of 14 cases of lung cancer (yield 85.7%) CB were diagnostic for immunohistochemical and molecular staining. After puncturing nodes, especially in hilar position not extensive bleeding was observed. Comparing to standard 21/22G EBUS-TBNA endoscopists underlined better flexion of loaded scope and sample adequacy and found non-significant differences in another biopsy details. CONCLUSIONS: The first Polish experience with use of Flex 19G EBUS-TBNA needle occurs to be similar in performance with standard technique with use of 22/21G needles and presents high diagnostic yield for lung cancer diagnostics, especially when preparing CB. A safety profile of the biopsy is acceptable.

ABSTRACT

INTRODUCTION    There are no widely accepted standards for the diagnosis of sarcoidosis. OBJECTIVES    The aim of this study was to assess the relative diagnostic yield of endobronchial ultrasound fine-needle aspiration (EBUS -FNA) and endoscopic ultrasound fine needle aspiration (EUS -FNA), and to compare them with standard diagnostic techniques such as endobronchial biopsy (EBB), transbronchial lung biopsy (TBLB), transbronchial needle aspiration (TBNA), and mediastinoscopy. PATIENTS AND METHODS    This was a prospective randomized study including consecutive patients with clinical diagnosis of stage I or II sarcoidosis. EBB, TBLB, and TBNA were performed at baseline in all patients. Subsequently, patients were randomized to group A (EBUS -FNA) or group B (EUS -FNA). Next, a crossover control test was performed: all patients with negative results in group A underwent EUS -FNA and all patients with negative results in group B underwent EBUS -FNA. If sarcoidosis was not confirmed, mediastinoscopy was performed. RESULTS    We enrolled 106 patients, of whom 100 were available for the final analysis. The overall sensitivity and accuracy of standard endoscopic methods were 64% each. When analyzing each of the standard endoscopic methods separately, the diagnosis was confirmed with EBB in 12 patients (12%), with TBLB in 42 patients (42%), and with TBNA in 44 patients (44%). The sensitivity and accuracy of each endosonographic technique were significantly higher than those of EBB+TBLB+TBNA (P = 0.0112 vs P = 0.0134). CONCLUSIONS    The sensitivity and accuracy of EBUS -FNA and EUS -FNA are significantly higher than those of standard endoscopic methods. Moreover, the sensitivity and accuracy of EUS -FNA tend to be higher than those of EBUS -FNA.

ABSTRACT

BACKGROUND: Sufficiently large, prospective randomized trials comparing suction drainage and nonsuction drainage are lacking. The aim of the present study was to compare the effects of suction drainage and nonsuction drainage on the postoperative course in patients who have undergone lung resection. METHODS: This prospective, randomized trial included patients undergoing different types of lung resections. On the day of surgery, suction drainage at -20 cm H2O was used. On the morning of the first postoperative day, patients, in whom the pulmonary parenchyma was fully reexpanded, were randomized in the ratio of 1:1. Patients assigned to group A continued with suction drainage, while those assigned to group B underwent nonsuction drainage. RESULTS: The study included 254 patients, with 127 patients in each group. The drainage volumes were 1098.8 mL and 814.4 mL in groups A and B, respectively (p = 0.0014). The times to chest tube removal were 5.61 days and 4.49 days in groups A and B, respectively (p = 0.0014). Prolonged air leakage occurred in 5.55% of patients in group A and in 0.7% of patients in group B (p = 0.032), and asymptomatic residual air spaces were noted in 0.8% of patients in group A and 9.4% of patients in group B (p = 0.0018). CONCLUSIONS: Nonsuction drainage is more effective than suction drainage with regard to drainage volume, drainage duration, and incidence of persistent air leakage. However, it is associated with a higher incidence of asymptomatic residual air spaces.

ABSTRACT

INTRODUCTION: Iatrogenic tracheobronchial injuries are rare. AIM: To analyse the mechanism of injury, symptoms and treatment of these patients. MATERIAL AND METHODS: Retrospective analysis of hospital records of all patients treated for main airway injuries between 1990 and 2012 was performed. RESULTS: There were 24 patients, including 21 women and 3 men. Mean time between injury and initiation of treatment was 12 hours (range: 2-48). In 16 patients the injury occurred during tracheal intubation, in 1 during rigid bronchoscopy, in 1 during rigid oesophagoscopy, in 1 during mediastinoscopy and in 5 during open surgery. Mean length of airway tear was 3.8 cm (range: 1.5-8). In 1 patient there was an injury to the cervical trachea and in the remaining 23 in the thoracic part of the airway. The treatment included repair of the membranous part of the trachea performed via right thoracotomy in 10 patients (in 1 patient additionally coverage with a pedicled intercostal muscle flap was used), a self-expanding metallic stent in 1 patient, suture of the right main bronchus and the oesophagus in 1, left upper sleeve lobectomy in 1, right upper lobectomy in 1, implantation of a silicone Y stent in 3, mini-tracheostomy in 1, and conservative treatment in 5 patients. CONCLUSIONS: Intubation is the most frequent cause of iatrogenic main airway injuries. Patients with these life-threatening complications require an individualised approach and treatment in a reference centre.

ABSTRACT

INTRODUCTION: A heterogeneous emphysema is one of the most severe forms of chronic obstructive pulmonary disease (COPD). In some cases, besides the standard pharmacotherapy, a new treatment option of emphysema can be used - bronchoscopic lung volume reduction (BLVR) with the use of intrabronchial valves. OBJECTIVES: To examine the health-related quality of life (HRQoL) of patients with severe emphysema after intrabronchial valve (IBV) implantation for the treatment of one lung. MATERIAL AND METHODS: From 2011 to 2013 a single centre prospective observational study was performed. The study assessed the effect of the therapeutic BLVR intervention, measured by St. George Respiratory Questionnaire (SGRQ). A statistical analysis by use of Wilcoxon test for dependent variables was performed. RESULTS: Twenty patients were enrolled to the study (mean age 63 ± 10 years), all ex-smokers with tobacco exposure 38 ± 11.3 packyears. After 3 months of IBV treatment the average SGRQ score improved significantly in total (-12.8; p < 0.001) and in domains and the differences were for: "symptoms" (-8.5; p < 0.001), "activity" (-13.9; p < 0.001) and "influence on life"(-13.5; p < 0.002). CONCLUSIONS: The presented study revealed a significant improvement of the quality in the life measured by SGRQ after IBV treatment for heterogeneous emphysema. For the first time our study showed the significant improvement of all three domains of SGRQ after IBV treatment.

ABSTRACT

INTRODUCTION: Endoscopic biopsy techniques are useful in the diagnosis of sarcoidosis. There is a need for randomized trials to establish where these procedures fit in the diagnosis of sarcoidosis. OBJECTIVES: The aim of the study was to compare the diagnostic yield of conventional transbronchial needle aspiration (TBNA) with endobronchial ultrasound-guided TBNA (EBUS-TBNA) and endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in stages I and II of pulmonary sarcoidosis. PATIENTS AND METHODS: Patients suspected of sarcoidosis were randomized to undergo TBNA or EBUS-TBNA or EUS-FNA. Patients with negative TBNA and EBUS-TBNA results underwent EUS-FNA and those with negative EUS-FNA results­EBUS-TBNA. If both tests were negative, patients in stage I were scheduled for mediastinoscopy (MS) and those in stage II­for transbronchial lung biopsy (TBLB). RESULTS: In 100 patients, 34 TBNA, 30 EBUS-TBNA, and 36 EUS-FNA procedures were performed at baseline. TBNA was positive in 20 patients (58.8%); EBUS-TBNA, in 23 (76.7%); and EUS-FNA, in 31 patients (86.1%). In patients with negative biopsy results, the second procedure was performed. The results of EUS-FNA were positive in 9 patients and of EBUS-TBNA­in none. Of 17 patients with negative results of both procedures, MS was performed in 6 patients and was positive in 2. In the remaining 11 patients, sarcoidosis was confirmed by TBLB. Sensitivity and accuracy of TBNA compared with EBUS-TBNA and EUS-FNA were 62.5% and 64.7%, 79.3% and 80%, and 88.6% and 88.9%, respectively. Sensitivity and accuracy of EBUS-TBNA were higher (P = 0.139) and of EUS-FNA were significantly higher compared with TBNA (P = 0.012). CONCLUSIONS: In stages I and II of pulmonary sarcoidosis, endoscopic ultrasound is a reasonable approach but EUS-FNA seems to be the method of choice.

ABSTRACT

INTRODUCTION: The exclusion of mediastinal involvement in patients with non-small cell lung cancer is essential for choosing an appropriate therapy. OBJECTIVES: The aim of the study was to analyze the ability of a new minimally invasive strategy combining positron emission tomography (PET), endobronchial ultrasound needle aspiration (EBUS-NA), and endoscopic ultrasound needle aspiration (EUS-NA) to exclude mediastinal nodal metastases of non-small cell lung cancer. PATIENTS AND METHODS: In a group of consecutive patients with primary non-small cell lung cancer, the preoperative assessment of medisastinal lymph nodes using PET, EBUS-NA, and EUS-NA. Patients in whom this minimally invasive staging protocol did not confirm mediastinal nodal metastases underwent pulmonary resection with systematic lymph node dissection. The negative predictive values of the combined EBUS-NA/EUS-NA as well as PET/EBUS -NA/EUS-NA were calculated. RESULTS: We analyzed data of 532 patients (367 men and 165 women; mean age, 65 years [range, 30-84 years]). Squamous carcinoma were diagnosed in 276 patients; adenocarcinoma, in 150; large cell carcinoma, in 22; adenosquamous carcinoma, in 40; small cell carcinoma, in 4; carcinoids, in 21; and other histological types, in 19. We performed 421 lobectomies, 55 pneumonectomies, 51 bilobectomies, and 5 sublobar resections. In all patients, systematic lymph node dissection was performed. The mean number of removed lymph nodes was 22. The negative predictive value of EBUS-NA/EUS-NA was 89.8% and of PET/EBUS-NA/EUS-NA-93.2%. CONCLUSIONS: Patients with lung cancer with negative results of PET, EBUS-NA, and EUS-NA are at low risk of mediastinal nodal metastasis. In these patients, invasive mediastinal staging may not be necessary.

ABSTRACT

This article presents a case report of a patient suffering from bullous emphysema and chronic obstructive pulmonary disease, who was diagnosed with tension pneumothorax after undergoing endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). Tension pneumothorax is a severe but rare complication of EBUS-TBNA. It can result from lung injury caused by the biopsy needle or, in patients suffering from bullous emphysema, from spontaneous rupture of an emphysematous bulla resulting from increased pressure in the chest cavity during cough caused by bronchofiberoscope insertion. The authors emphasize that patients should be carefully monitored after the biopsy, and, in the case of complications, provided with treatment immediately in proper hospital conditions. Patients burdened with a high risk of complications should be identified before the procedure and monitored with extreme care after its completion.

ABSTRACT

OBJECTIVES: The aim of the study was to compare diagnostic utility of combined (i.e. transbronchial and transoesophageal) ultrasound imaging with needle biopsy of the mediastinum in lung cancer (LC) staging, (a) by use of a single ultrasound bronchoscope (CUSb) and (b) by using two scopes (CUS). METHODS: In consecutive LC patients, clinical stage IA-IIIB the CUS or CUSb was performed under mild sedation and, if negative, underwent lung resection with confirmatory systematic lymph node dissection. RESULTS: From 214 LC patients, 110 underwent CUS and 104 underwent CUSb (618 biopsies); both revealed metastases in 50% of cases. There was 'minimal N2' in 11 of 14 false negative patients. Diagnostic sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of CUS was 91.7%, 98%, 94.6%, 98.2% and 90.7% respectively and of CUSb was 85%, 93.2%, 88.5%, 94.4%, 82%, respectively with no significant difference in yield of CUS vs CUSb (P = 0.255 and P = 0.192). The mean time of CUS (25 ± 4.4 min) was significantly longer as compared to CUSb (14.9 ± 2.3 min) (P < 0.001). No severe complications of either method were observed. CONCLUSIONS: The combined ultrasound imaging of the mediastinum by use of CUSb is significantly less time-consuming and equally as effective and safe as the use of CUS for LC staging.

ABSTRACT

INTRODUCTION: Besides radio logical methods (especially positron emission tomography combined with computed tomography), endoscopic techniques including transbronchial needle aspiration (TBNA) of mediastinal lymph nodes play an important role in lung cancer staging, thus having a significant effect on further patient management. OBJECTIVES: The aim of the study was to investigate the diagnostic value of blind TBNA in staging of lung cancer, using systematic mediastinal lymph node dissection (SLND) at thoracotomy as a confirmatory test. PATIENTS AND METHODS: Patients with lung cancer and enlarged mediastinal lymph nodes on computed tomography scans underwent TBNA. Non-small cell lung cancer (NSCLC) patients with negative TBNA or with single-level N2 disease underwent thoracotomy with appropriate pulmonary resection and with SLND. RESULTS: In 84 lung cancer patients, 166 TBNA were performed. Metastatic lymph node involvement was identified in 57 patients (67.9%). There were 10 patients (11.9%) with small cell lung cancer. Of the 74 NSCLC patients, TBNA revealed meta stases in 48 (64.9%). Twenty-four TBNA-negative patients (32.4%) and 4 patients (5.4%) with single-level N2 disease underwent pulmonary resection with SLND. In 8 of 28 operated patients (28.6%), N2 meta static nodes were identified. The per-patient analysis showed the sensitivity of TBNA to be 81.5%, specificity - 100%, accuracy - 86.5%, and negative predictive value (NPV) - 66.7%. CONCLUSIONS: Our results suggest that TBNA may be a useful method for initial NSCLC staging in patients suspected of N2-3 disease. Positive TBNA in 1 station only should not be considered as a true single-level N2 disease, because of a relatively low NPV for TBNA.

ABSTRACT

The study presented a case of an esophago-pericardial fistula during the course of primary esophageal carcinoma. The occurrence of this was insidious, with the first symptom being pericardial sac tamponade. After full diagnostics the patient was qualified for surgery. The patient was subjected to videothoracoscopy, left-sided thoracotomy, fenestration, and pericardial sac drainage, with placement of a self-expandable esophageal prosthesis. During the course of the disease the patient required bronchial tree patency restoration and prosthesis application. The patient survived 329 days.
