    ABSTRACT: Introduction: In the prospective study was aimed to be the actual node staging identified sentinel and mediastinel lymph nodes and mapping in patient with operable non-small cell lung carcinomas. Materials and Methods: Twelve patients underwent pulmonary resections due to non-small cell bronchial carcinoma in the study were included . Intraoperatively, by injecting Tc99m to peritumoral tissues, average 96 minutes later, radioactivity levels of the tumoral tissue and lymph nodes were measured. All patients were evaluated by bronchoscopy for endobronchial lesions. The patients were scanned for the metastasis of solid organs in order to pre-operative staging. Results: The interlobar lymph node stations as a sentinel lymph nodes were detected in 45% of the patient. Lobes of specific, lymph node stations and skip metastasis detected lymph nodes were identified. Sentinel lymph node was in 77% of patients at the level N1 and in 66%of patients at the level N2. It were at two different stations in 66% of patients and at single-station in 33% of patient . In 1 (11%) of 9 patients identified sentinel lymph node, the metastasis has been reported by the routine histopathological examination. Conclusion: To detection sentinel lymph node, micrometastasis also allows for a more detailed pathological examination. It provides making true node staging in patients and postoperative therapy helps to organize appropriate support with non-small cell lung cancer.

    ABSTRACT: Pulmonary alveolar microlithiasis is characterized by the presence of calcospherites in alveolar spaces. Sporadic cases are more common, but the disease also presents in an inherited familial form. The greatest number of reported cases is from Europe and especially Turkey. We present a 43-year-old female with complaints of dyspnea for many years. She had a suspicious familial history of pulmonary alveolar microlithiasis. The surgical lung biopsy specimen appeared gritty and firm. Histological sections showed diffuse involvement of the lung parenchyma by innumerable tiny calcospherites. Genetic studies showed a homozygous c.316G > C (p.G106R) mutation in exon 4 and confirmed the diagnosis of pulmonary alveolar microlithiasis. The present report aims to contribute to the literature with a pathologically and genetically confirmed new case to add insight into the etiology of this rare disease. This case confirms an autosomal recessive inheritance and does not support the role of non-genetic and other factors in the pathogenesis of pulmonary alveolar microlithiasis.

    ABSTRACT: Expressions of various biomarkers in non-small cell lung cancer (NSCLC) have been linked with the prognosis and involvement of mediastinal lymph nodes. In this study, we utilized recursive partitioning analysis (RPA) by using P53, c-erb-B2, and P-glycoprotein (PGP) expressions evaluated by immunohistochemistry to estimate retrospectively the likelihood of the occult N2 mediastinal lymph node involvement in patients with operable NSCLC. In univariate tests, immunohistochemical staining of the primary tumor for these 3 markers in 61 patients undergoing surgery revealed no direct relationship with the N2 involvement. However, RPA demonstrated in patients aged <75 and with >/=4 mediastinal lymph nodes removed that, high PGP expression frequency (>/=20%) predicted an increased likelihood of the N2 involvement (46.7%, R(2) = 0.25). Univariate nominal logistic regression analysis revealed that RPA group affiliation, and the number of mediastinal lymph nodes resected (logarithmic transformation) were associated with the metastasis to N2 lymph nodes (chi(2) = 17.59, p = 0.0005, and chi(2) = 2.40, p = 0.0654, respectively). Multivariate analysis confirmed that only RPA group affiliation predicted the N2 involvement (chi(2) = 14.63, p = 0.0022). This study shows for the first time that PGP expression of the primary tumor may help to predict the occult N2 mediastinal lymph node involvement in NSCLC. Thus, further research is required to understand whether PGP expression may aid in the decision process for preoperative mediastinoscopy.

    ABSTRACT: Various biomarkers have prognostic value in non-small cell lung cancer (NSCLC). We aimed to identify the roles of P53, c-erb- B2 and p-glycoprotein (pgp) as prognostic factors, independently or in conjunction with each other, in operable NSCLC. Seventy operable NSCLC cases were retrospectively evaluated for P53, c-erb-B2 and pgp expression patterns by immunohistochemistry. An unsupervised hierarchical cluster analysis of the 3 biomarkers was conducted. Univariate and multivariate survival analyses were made in relation to cluster affiliation. Cluster analysis yielded two distinct subgroups; group A of high biomarker expressors (n=26, 37%), and group B (n=44, 63%) of low expressors. Cluster affiliation with regard to tumor histology (interaction term) was independently associated with Recurrence- free survival (RFS) and Overall survival (OAS) with a Hazard Ratio (HR) of 5.88, P=0.003, and HR=4.68, P=0.012, respectively. The median OAS times for cluster A and B in the squamous cell carcinoma subgroup were 328 and 596 days, whereas the corresponding figures in the non-squamous cell carcinoma subgroup were non-measurable and 298 days. In operable NSCLC there may be different relationships of P53, c-erb-B2 and pgp with patient outcome for different tumor histologies. The prognostic utility of cluster affiliation with regard to these biomarkers, and in relation to tumor histology, deserves further testing.

    ABSTRACT: To investigate the management outcomes of patients who developed tracheal stenosis after tracheostomy or intubation, we reviewed the courses of 45 patients who had experienced tracheal stenosis at a single institution, over 19 years from February 1985 through January 2004. There were 38 tracheal and 7 infraglottic stenoses. Twenty-nine stenoses were associated with the stoma, 12 with the cuff, and 2 with the endotracheal tube resulting in infraglottic lesions; the remaining 2 were double stenoses. Eleven patients were treated by bronchoscopic surgery, and 34 patients were treated by tracheal or laryngotracheal resection. The overall success rate was 93%. The complication rate was 18%. A 2nd operation was required in 3 patients, and 1 of the 3 died of sepsis. Our management strategy of treating tracheal stenosis with resection and end-to-end anastomosis has been associated with good outcomes. Management of infraglottic stenosis is difficult, particularly when there is a large laryngeal defect or when there have been previous surgical attempts at the same site.

    ABSTRACT: An 18-year-old male preferred to our clinic with hemoptysis, cough, dyspnea and stridor. A wide-based polypoid tumor that was localized at the right wall of the distal trachea was observed over 3 cm from the carina by flexible bronchoscope. Computerized tomography showed an intraluminal soft tissue density mass in the trachea. Though right thoracotomy, a tracheal resection that contains three rings of the trachea with malignant lesion was performed. Pathologic examination reported a tracheal mucoepidermoid carcinoma. The patient is alive without recurrence three years after surgery.

    ABSTRACT: We report two cases of intrathoracic migration of Steinman wire used for the treatment of the fracture and shoulder dislocation. The migrations were symptomatic with back pain in our cases. The treatment involved removing of the pin via thoracotomy. The postoperative course was uneventful. Intrathoracic migration of Steinman wires should be expected in fixation of the shoulder problems. To avoid this complication, threaded pins have to be used in surgery of the shoulder region.

    ABSTRACT: Esophageal strictures and esophagorespiratory fistulas are complications of malignant esophageal tumors, which are difficult to manage. The efficacy of self-expanding metal stents (SEMS) for palliation of malignant esophageal strictures and fistulas was investigated prospectively. Forty-three SEMS were inserted in 41 patients with malignant esophageal stricture or fistula. Our series included 32 men and nine women, of whom median age was 61.4 years. Twenty nine stents were inserted for stricture, ten for esophago-tracheal fistula, and four esophago-pleural fistula. Stents were inserted endoscopically under fluoroscopic control. SEMS implantation was technically successful in 40 of 41 patients. A second stenting was needed in two patients. Median dysphagia score improved from 3.4 to 1.3. The covered SEMS was succesful in completely sealing 85.7% of the fistulas. Complication occurred in 11 (26.8%) patients. Especially in the case of tumor stenoses in the distal esophagus, complication rate was higher (44%). In total six patients (14.6%) died after stent placement during early postoperative period. Procedure-related mortality was 4.8% (2/41). We conclude that treatment of malignant esophageal obstructions, including esophagorespiratory fistulas, with SEMS is an alternative palliative procedure. Furthermore SEMS implantation seems more safe in the case of tumor stenoses locating in the middle esophagus.

    ABSTRACT: The clinical presentation of the bronchogenic cyst is variable, from respiratory distress at birth to late appearance of symptoms. In order to determine clinical features and treatments, we retrospectively studied the medical records and pathology reports of all patients with bronchogenic cysts (n = 22) referred to our surgical department from February 1985 through January 2002. They included 18 male and 4 female patients with an age range of 1 to 38 years (average, 16.4 years). There were 14 mediastinal, 2 hilar, and 6 intrapulmonary bronchogenic cysts. Symptoms were present in 18 of the 22 patients. Cough was the most common symptom (45%). Ten patients (45%) presented with complications: severe hemoptysis, pneumothorax and pleuritis, esophageal compression, infected cyst, and postobstructive pneumonia. In all patients, complete resection of the bronchogenic cyst was performed by thoracotomy A postoperative sequela occurred in only 1 patient, who had a persistent air leak. There were no late sequelae, nor was there a recurrence of the cyst. The follow-up period ranged from 8 months to 12 years (mean, 5.2 years). Because a confident preoperative diagnosis is not always possible and because complications are common, we recommend surgical resection of all suspected bronchogenic cysts in operable candidates.

    ABSTRACT: We report herein a rare case of complete congenital sternal cleft (absent sternum) and anterior pericardial defect in association with pectus excavatum. In neonates with absent sternum, the sternal bars can be easily approximated by simple suture, due to the flexibility of the cartilaginous thorax. There is also little danger of cardiac compression when the repair is performed early in life. If reconstruction is delayed, the increased rigidity of the chest wall and the physiologic accommodation of the thoracic organs to the circumference of the chest render simple approximation impossible, without serious compromise of the heart and lungs. Our patient was a 13-year-old girl, whose case was particularly unusual because of the association of sternal cleft with pectus excavatum. After surgical correction of the pectus excavatum, we were able to construct a sternum by incising the lateral border of each sternal bar, thereby creating flaps that we sutured together at midline. The sternal bars were then approximated by loops of nonabsorbable suture around their circumference. The patient had an uncomplicated course, and at the 12-month follow-up visit, her sternal appearance was normal.

    ABSTRACT: We report the case of a 33-year-old woman who was admitted to our clinic with the diagnosis of chronic arterial occlusion of the right lower extremity. Preoperative angiography suggested an iliofemoral atherosclerotic occlusion. During surgery multiple hydatid cysts causing iliofemoral occlusion were found and excised. Arterial reconstruction was performed using an iliofemoral bypass technique with a polytetrafluoroethylene vascular graft. This case emphasizes that, in sheep-raising countries or in patients from such countries, primary vascular echinococcosis should be considered in the differential diagnosis of chronic arterial occlusion.

    ABSTRACT: A 28-year-old man, who presented with pleural and pericardial chylous effusion secondary to superior vena cava syndrome, was diagnosed with Behcet's syndrome. A pericardial window was created by video-assisted thoracic surgery to relieve cardiac tamponade, and this technique also enabled lung biopsy, pleural abrasion, and drainage of the pleural effusion. We report this case because of its rarity. To the best of our knowledge, the literature contains no other report of the use of video-assisted thoracic surgery for creating a pericardial window for the treatment of cardiac tamponade in a case of Behcet's syndrome.

    ABSTRACT: Clinical features of the first and second primaries in patients with multiple malignancies have not been extensively studied. We compared patient and treatment characteristics of the primary malignancy in 48 consequent multiple primary cancer patients with those of the second primary in the same cohort. The second primaries comprised fewer breast cancers; 29.2% of primaries as opposed to 10.4% of second tumors were breast cancer (P = 0.049). In addition, primary tumors tended to be at a lower TNM stage than secondary tumors (P = 0.060). The median overall survival after the diagnosis of the first primary for the whole cohort was 22.3 years (95% CI, 2.0-42.5) and the median time to presentation of the second malignancy was 38 months after the diagnosis of the first primary (range, 0 to 384). Therefore, the prognosis of cancers in the multiple malignancy group appears to be good and they appear to have an indolent clinical behavior. Thus, we recommend a long screening time for secondary tumors after a curative treatment in patients with common cancers, taking into account the different occurrence patterns of second primaries with respect to first primaries.

    ABSTRACT: Abstract Therapeutic approaches to lung adenocarcinomas differ because of their heterogeneous morphologies, prognoses, and clinical features. For this reason, new histopathologic classifications for lung adenocarcinomas were done by the International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society to form subtypes with homogeneous prognoses. There are limited clinical data in the literature on the prognosis of the subgroups formed according to the new classification. A total of 86 patients with adenocarcinoma who had undergone pathologic stages I and II curative resection and mediastinal lymph node dissection were retrospectively analyzed according to the seventh TNM staging system revised by the Union for International Cancer Control/American Joint Committee on Cancer. Histologic subtyping was reassessed according to the dominant histopathologic morphology. When survival rates of lung adenocarcinomas were compared according to their localizations, it was observed that adenocarcinomas localized to the right hemithorax had a longer survival than the ones with left hemithorax localization (P = 0.026). When necrosis was taken into account, it was seen that necrosis rate was higher in solid predominant type compared with other types, whereas it was lower in acinary type (P = 0.046). When peritumoral lymphovascular invasion data were assessed, it was observed that disease-free survival was influenced in a negative fashion (P = 0.018). New histopathologic classification of adenocarcinomas has been a step forward to attaining homogeneous groups, but when the biologic heterogeneity of the adenocarcinomas is taken into account, the authors believe that considering the peritumoral lymphatic vascular invasion, left hemithorax localization, and tumoral necrosis entities in the upcoming TNM classification will contribute to evaluating the prognosis.

    ABSTRACT: Abstract Our study indicated the relationship between tumor length and clinicopathologic characteristics as well as long-term survival in esophageal cancer. A total of 116 patients who underwent curative surgery for thoracic esophageal cancer with standard lymphadenectomy in 2 fields between 2000 and 2010 were included in the study. The medical records of these patients were retrospectively reviewed. The patients with tumor length ≥3 cm had a highly significant difference in the involvement of adventitia and lymph node stations. The patients with tumor length ≤3 cm had significantly lower rates of involvement of the adventitia and lymph node stations. Tumor length could have a significant impact on both the overall survival and disease-free survival of patients with resected esophageal carcinomas and may provide additional prognostic value to the current tumor, node, and metastasis staging system before patients receive any cancer-specific treatment.
