Objective To improve our knowledge of primary benign tracheobronchial tumors and increase the early diagnosis rate. Method The clinical and imaging features of 22 patients with benign tracheobronchial tumors were retrospectively analyzed. The lesions were surgically or pathologically confirmed as schwannomas(n=2),lipomas(n=3),hamartomas(n=3),leiomyomas(n=9),inflammatory myofibroblastoma(n=1),and pleomorphic adenomas(n=2).The early symptoms were concealed and atypical,accompanied by misdiagnoses at different time points.The tumors were located at trachea in 5 patients and at bronchus in 17 patients.All lesions manifested as intraluminal growth with mild to moderate enhancement,without thickening of the tracheobronchial wall.They had smooth margins and wide basements.The lesions were cast-shaped and occluded the lumen in 3 cases;in the remaining 19 cases,the lesions appeared as round or oval nodules. Conclusions Primary benign tracheobronchial tumors are rare.Patients with repeated cough and expectoration that respond poorly to treatment should be screened for benign tracheobronchial tumors.On CT,the benign tracheobronchial tumors are small intraluminal nodules with the smooth surface and wide basement,without thickening of the wall.

PURPOSE: Endobronchial metastasis is defined as documented extrathoracic malignancies metastatic to the endobronchus within a bronchoscopically visible range. Although the clinical and radiologic findings of endobronchial metastasis are similar to primary lung cancer, treatment and prognosis may be different. We hereby investigated the clinical, radiologic and bronchoscopic aspects of endobronchial metastases (EBM) in Korean patients. MATERIALS AND METHODS: A total of 43 patients with EBM who underwent bronchoscopic biopsies from June 1991 to December 2009 at Severance Hospital, Yonsei University College of Medicine in Seoul, Korea, were analyzed retrospectively. We evaluated clinical, radiologic and bronchoscopic characteristics of EBM. RESULTS: The patients consisted of 27 males and 16 females and their ages ranged from 18 to 77 years. The common primary cancers related to EBM were rectal (16.3%), colon (11.6%), breast (9.3%) and uterine (9.3%) cancers. The mean interval from diagnosis of primary cancer to EBM was 36 months, and the mean survival duration from diagnosis of EBM was 16.1 months in 33 deceased patients. CONCLUSION: EBM develop in various types of malignancies at various times with unremarkable manifestations. Therefore, physicians should consider the possibility of EBM, especially if a patient has a history of any malignancy, regardless of respiratory symptoms. Respiratory symptoms related with EBM can be treated by various safe procedures.

A fibroepithelial polyp of the bronchus is a rare, benign, and endobronchial tumor, histologically consisting of fibrovascular stroma covered by normal respiratory epithelium. We report a case of a fibroepithelial polyp arising from the left main bronchus. On CT, a characteristic lobulating contour of the endobronchial nodule was well visualized, which histopathologically represented a typical papillary growth pattern of the nodule. Such a lobulating contour of the nodule might help make a correct diagnosis of this rare disease among other various endobronchial neoplasms.

OBJECTIVEEndobronchial metastases (EBM) secondary to extrapulmonary solid malignant tumors are rare but may occur. The most common extrathoracic malignancies associated with EBM are colorectal, renal and breast cancer. This study aimed to evaluate the clinicopathological aspects of EBM from breast cancer and the prognosis of the patients.

METHODSClinicopathological data of 11 cases diagnosed as EBM from breast cancer treated in our hospital from 2003 to 2010 were re-evaluated. Their symptoms, recurrence interval, radiological features, histopathological properties, and prognosis were assessed.

RESULTSEleven cases were diagnosed by bronchoscopic bronchial biopsy. The median interval from diagnosis of breast cancer was 57 months (range: 11 - 189 mo). All patients had other proven metastases when the EBM was diagnosed. The most frequently observed symptoms were cough (8 cases). Interestingly, two patients were asymptomatic. Hilar mass (5 cases) was a common radiological finding. No disaccordance between the hormone receptor status in the primary and metastatic lesions in these patients was found. The median survival after EBM diagnosis was 21 months (range: 6 - 36) with four patients still alive and one of these four patients was surviving more than 7 years.

CONCLUSIONSOn average, EBM is diagnosed about 5 years after the diagnosis of breast cancer, which is a relatively long lead time, but the median survival time is short, as 21 months in our group. The treatment plan must be individualized, because in some cases, long-term survival can be expected.

Extra-adrenal myelolipomas are extremely rare, especially in bronchus and lung. Up to now, only nine cases of intra pulmonary lesions have been reported all over the world. Here we describe a new discovered pulmonary-bronchus myelolipoma in a 53-year-old man, which is different from the previously reported ones. And we mainly comment on the pathology and diagnosis, comparing with the findings of the extra-adrenal cases reported in Chinese literature.

BACKGROUNDPatients with central tracheobronchial benign or malignant lesions who have not recieved surgical treatment can be treated by interventional techniques, such as laser, afterloading radiotherapy, cryotherapy, photodynamics treatment, radiofrequency ablation and stenting, etc. The accuracy of the invasive depth of central lesion in tracheobronchial wall plays an important role in making interventional treatment plan. This study used radial probe endobronchial ultrasound (RP-EBUS) scanning to evaluate the accuracy of the invasive depth of central lesions in tracheobronchial wall, and the influence of RP-EBUS scanning in treatment plan making and guidance.

METHODSThis was a prospective study of consecutive patients with central tracheobronchial lesions found by CT or bronchoscopy. We performed EBUS scanning after common bronchoscopy under local anesthesia. A radial ultrasonic probe (2.0 mm in diameter with 20-MHz frequency) with a balloon sheath was introduced through the 2.8-mm-diameter channel of a flexible bronchoscope. The balloon at the tip of the probe was inflated with distilled water until coupling with the airway wall under endoscopic control. The circular image of EBUS, which revealed the layered structure of the tracheobronchial wall, could be achieved.

RESULTSTotal of 125 patients were enrolled in the study. Thirty patients underwent surgical operation and pathologically proved the RP-EBUS diagnosis accuracy of tumor invasive depth in tracheobroncial wall was 90% (27/30), sensitivity and specificity were 88.89% (24/27) and 100% (3/3), respectively. In response to EBUS images, 40 approaches were altered or guided: lymph-node metastasis and compressive lesions was diagnosed by EBUS-guided transbronchial needle aspiration (TBNA) (n = 8); Lesions ablation with laser or electricity were stopped when EBUS demonstrated close range with vessels or perforation possibility (n = 13), stents size were changed (n = 14), operation was canceled (n = 3) and foreign body was removed (n = 2). No complication associated with the use of EBUS was observed.

CONCLUSIONRP-EBUS can be a useful tool in assessing the central lesion invasive depth to the tracheobronchial wall.

BACKGROUND/AIMS: We made a systematic review and evaluation of endoscopic cryotherapy of endobronchial tumors, investigating safety and efficacy. METHODS: Qualified studies regarding endoscopic cryotherapy of lung tumors were systemically evaluated using available databases according to predefined criteria. RESULTS: In total, 16 publications were included in the final assessment. A narrative synthesis was performed because a formal meta-analysis was not viable due to the lack of controlled studies and study heterogeneity. Overall success rates for significant recanalization of the obstruction were approximately 80%, although they varied, depending on disease status in the patient population. Complications from the procedure developed in 0-11.1% of cases, most of which were minor and controlled by conservative management. Although limited data were available on comprehensive functional assessment, some studies showed that respiratory symptoms, pulmonary function tests, and performance status were significantly improved. CONCLUSIONS: Endoscopic cryotherapy was found to be a safe and useful procedure in the management of endobronchial tumors although its efficacy and appropriate indications have yet to be determined in well-designed controlled studies.

OBJECTIVETo evaluate the long-term efficacy of bronchial arterial infusion (BAI) chemotherapy in the treatment of centeral non-small cell lung cancer.

METHODSFifty-eight patients with central non-small-cell lung cancer, who were assessed as difficult operable or non-operable by imaging examination, received BAI of cisplatin, epirubicin and mitomycin alone or in combination. It includes 51 cases of squamous cell carcinoma, 6 cases of adenocarcinoma and 1 case of adenosquamous carcinoma. The cinical stage before BAI wasIIb in 3 cases, IIIa in 26 cases and IIIb in 29 cases. Long term follow-up was conducted and the results were statistically analyzed.

RESULTSThe total effective rate of BAI was 43.1%. The mediam survival (MS) of all 58 patients was 29.1 months. 31 patients after BAI became operable and were resected, had a median survival of 65.2 months. 27 patients after BAI were not resected and had a MS of 15.9 months. There was a significant difference between the patients who had been resected and not. The MS of IIIa stage patients was 39.0 months, and IIIb stage 20.4 months.

CONCLUSIONBronchial arterial infusion chemotherapy is a better choice with a definite efficacy for treatment of center-based NSCLC patients, estimated as difficult operable but without distant metastasis.
