Adenoid cystic carcinoma is a rare primary tracheal tumor and this tumor behave slow growth, low-grade ma!ignancy, locally invasion and long-term host survival. Operation with the primary goal of complete excision is the treatment of choice but this tumor require excessive margins at surgical removal because of locally invasive cancer. A 45-years-old male patient had complained paroxysmal coughing from 1 year ago prior to admission and was diagnosed pre-operatively as endotracheal adenoma. He had been treated by operation, and combined with radiotherapy by 4 MeV. Lineal Accelerator. The tracheal mass was removed by tracheo-bronchotomy transpleurally and right total pneumonectomy was performed. There was post-operative course uneventfully and no post-operative complication. The patient Is free from cancer until post-operative 1 year clinically and alive with good healthy.

Tracheal stenosis can be classified into intrinsic stenosis secondary to tracheal inflammatory lesion or mass effect and extrinsic stenosis secondary tumors of thyroid, esophagus and mediastinum. Extrinsic stenosis which is frequently encountered in clinical setting could be often overlooked due to mild symptom. Recently, even with the increasing interest in extrinsic tracheal stenosis there are limitation in it's diagnosis and treatment. The purpose of this study is to provide guidance in the diagnosis and treaonent of extrinsic tracheal stenosis. Here, we report the etiology, symptoms, radiologic findings, pulmonary fuction finding, treatment and its results in 26 cases of extrinsic tracheal stenosis. Causes of extrinsic tracheal stenosis included compression of aiway by thyroid benign tumor in 13 cases to be the most common, next by thyroid malignancy in 9 cases, metastatic mediastinal turner in 2 cases, 1 case each for esophageal cancer and parathyroid cancer. In 3 cases simple tracheal resection and end to end anastomosis were done, 1 cases underwent total laryngectomy, and 8 cases were treated by conservative management, where all cases failed in treatment. The remaining 14 cases were successfully treated by removing the causes and maintaining tracheal tube insertion for amount of time. Extrinsic tracheal stenosis due to benign conditions were treated satisfactorily by removing mass, however with the malignant causes there was considerable amount of difficulty in treatment.

A 57 year old human immune virus(HIV)-positive male presented with a progressive dyspnea for 6 months. Chest CT showed multiple polypoid masses arising from upper tracheal wall. Bronchoscopic examination revealed that multiple large cauliflower-like polypoid tumors was obstructing tracheal lumen. They were diagnosed as multiple squamous papillomas and were removed by Nd:YAG laser photocoagulation and rigid bronchoscopic treatment. The tumors were histologically diagnosed as squamous papilloma infected with human papilloma virus(HPV) type 6 and 11 in in-situ hybridization. Rigid bronchoscopy might be safer and more efficient than flexible bronchoscopy for the treatment of multiple tracheal papillomatosis obstructing tracheal lumen because of easy establishment of airway patency and direct use of rigid bronchoscope itself for tumor resection.

Tracheal cancer is rare and accounts for approximately 0.03% of all malignancies. Because of atypical symptoms, tracheal cancer can be misdiagnosed as obstructive lung disease, or tumors of thyroid or lung. Among patients of previous head and neck cancer, other primary cancer may accompany which called "econd primary cancer". We report a case of patient with tracheal cancer 3 years after definite radiation therapy of laryngeal cancer with a review of related literatures.

In spite of great advances in surgical treatment during past several decades, surgery of the trachea failed to develop correspondingly, partly because of relative rarity of the tracheal lesions and partly because of difficulties in surgical technique and anesthesia. Surgical diseases of the trachea are largely obstructions due to neoplasm or cicatrical stenosis and tracheal malacia. The present treatment of respiratory failure, using cuffed endotracheal and tracheostomy tubes, has produced, apparently with increasing frequency, tracheal stenosis, tracheomalized tracheal erosion. Surgery is presently the only reasonable way to treat stenotic lesions of the tracheobronchial tree. In the case of tumors, the current trend has been that of radical excision. Primary end-to--end reconstruction of the trachea has been generally recognized as the ideal method of repair following resection. However, for decades it was believed that a maximum of four tracheal rings only might be excised and primary healing achieved with safety. A great variety of procedures, developed by numerous investigations and directed at tracheal substitution, have almost invariably met with discouraging results. A meticulous study done by Grillo and associates on autopsy specimens has shown that an average 6.4cm of mediastinal trachea can be safely resected by full mobilization of the right lung and transplantation of the left main bronchus into the bronchus intermedius. Recently, we experienced a case of successful resection of a tumor of the tracheal carina and primary tracheo-left main bronchial anastomosis at the Department of Thoracic & Cardiovascular Surgery, the National Medical Center in Seoul. The patient, a 29-year-old man, was admitted to the hospital with complaints of dyspnea and cough. On admission, chest film showed hydropneumothorax on the right. After closed thoracostomy, hydropneumothorax disappeared, but hazy densities, developed in the right middle and lower lung fields, resisted to treatment. Bronchoscopy uncovered irregular tumor covering the carina and the right main bronchus, and biopsy indicated well differentiated squamous Cell carcinoma. Operation was performed on July 2, 1975. A right postero-lateral thoracotomy was used. Excision involved the lower trachea, the carina, the left main bronchus and the right lung. This was followed by direct anastomosis between the trachea and the left main bronchus. Bronchography was done on 17th postoperative day revealed good result of operation without stricture at the site ofanastomosis. About one month after the operation symptoms and signs of bronchial irritation with dyspnea developed, and these responded to respiratory care. On 82nd postoperative day, sudden dyspnea developed at night and the patient expired several hours later. Autopsy was not done and the cause of death was uncertain.

Objective: To investigate the potential value of ¹⁸F-fluorodeoxyglucose (FDG) PET/CT in predicting the survival of patients with primary tracheal malignant tumors. Materials and Methods: An analysis of FDG PET/CT findings in 37 primary tracheal malignant tumor patients with a median follow-up period of 43.2 months (range, 10.8-143.2 months) was performed. Cox proportional hazards regression analyses were used to assess the associations between quantitative ¹⁸F-FDG PET/CT parameters, other clinic-pathological factors, and overall survival (OS). A risk prognosis model was established according to the independent prognostic factors identified on multivariate analysis. A survival curve determined by the Kaplan-Meier method was used to assess whether the prognosis prediction model could effectively stratify patients with different risks factors. Results: The median survival time of the 37 patients with tracheal tumors was 38.0 months, with a 95% confidence interval of 10.8 to 65.2 months. The 3-year, 5-year and 10-year survival rate were 54.1%, 43.2%, and 16.2%, respectively. The metabolic tumor volume (MTV), total lesion glycolysis (TLG), maximum standardized uptake value, age, pathological type, extension categories, and lymph node stage were included in multivariate analyses. Multivariate analysis showed MTV (p = 0.011), TLG (p = 0.020), pathological type (p = 0.037), and extension categories (p = 0.038) were independent prognostic factors for OS. Additionally, assessment of the survival curve using the Kaplan-Meier method showed that our prognosis prediction model can effectively stratify patients with different risks factors (p < 0.001). Conclusion: This study shows that ¹⁸F-FDG PET/CT can predict the survival of patients with primary tracheal malignant tumors. Patients with an MTV > 5.19, a TLG > 16.94 on PET/CT scans, squamous cell carcinoma, and non-E1 were more likely to have a reduced OS.

Because of location, a mediastinal mass may cause complications such as a major airway obstruction, a superior vena caval obstruction, and cardiac compression during general anesthesia. The patient's condition need to be assessed by several methods to predict the risks associated with general anesthesia. The authors took computed tomographs for a preoperative evaluation of two patients with an anterior mediastinal mass, and the risk of perioperative complications was predicted by measuring the tracheal area. The patients were managed according to the preoperative evaluation but severe ventilation impairments were encountered during anesthesia. In one patient, stable ventilation could not be maintained until spontaneous breathing appeared. The operation was cancelled and the patient was brought into the ICU. In the other patient, a tracheal tube was inserted deeper in an attempt to pass the narrowed tracheal portion due to mediastinal tumor compression resulting in improved ventilation.
