Thirteen histologically proven cases of bronchial carcinoid from the literature and eight cases from the Armed Forces Tumor Registry, all under 20 yr of age, are presented. Hemoptysis, cough, and pneumonia were the most frequent presenting complaints. Bronchoscopy defined the lesion in all 16 cases so studied. Gross and microscopic pathology is briefly described, and treatment in these cases outlined. A good long-term prognosis can be expected, except in those cases with a long delay in diagnosis.

17 cases with bronchial carcinoid were reported. 16 cases of them were proved pathologically after pulmonary resection, and the remaining one was confirmed histopathologically through bronchoscopic biopsy. 64.7% was under 40 years of age. The main clinical manifestations were cough, hemoptysis, fever and repeated pneumonitis. In one patient, the carcinoid was associated with Cushing's syndrome. Chest roentgenograms showed lesions centrally located in 12 cases, and peripherally located in 5 cases. Histological examination revealed 15 typical and 2 atypical carcinoid tumors. This disease was usually misdiagnosed as lung cancer, tuberculoma and benign tumors. Chest X-ray examination and fiberoptic bronchoscopic biopsy are helpful to the diagnosis of the disease. Pulmonary resection was performed in 16 cases. Two patients had hilar lymph node metastases, one of them had also involvement of pericardium. There was no operative mortality. In the follow-up study, the disease-free actuarial survival following pulmonary resection was 92.9% at 5 years. 2 patients died. One died of respiratory failure 4 months after pneumonectomy, the other died of pericardium involvement of carcinoid 8 months after operation. Resection is the only effective treatment for bronchial carcinoid.

We present a retrospective study of twenty patients in whom bronchial carcinoids, and five, peripheric. One case met the criteria of atypical carcinoid. The mean age of presentation was 46.66 +/- 17.07 years (15-76), with predominance of the female gender (3:2). Twenty per cent of patients were asymptomatic and in the remainder, the diagnosis suffered an average delay of 19 months since the appearance of symptoms. Such symptoms were cough (50%), recurrent pneumonias (40%), fever (35%), hemoptysis (35%), thoracal pain (30%), carcinoid syndrome (10%) and consumptive syndrome (5%). The radiology showed lobular or segmentary atelectasis (40%), nodule/mass (30%), lobular or segmentary consolidation (20%), obstructive pneumonitis (5%) and atypical pleural effusion (5%). Direct endoscopic vision offered a sensitivity of 84.6%, while transbronchial biopsy, just 69.2%. Metastasis in mediastinal, suprarenal, thyroid and brain gangliar chains were detected.

Twenty-seven main bronchial resections (19 left, 8 right) were performed without pulmonary resection between 1975 and 1991. The patients were 17 men and 9 women with an average age of 35 years (range, 20 to 65 years). Tumors comprised 55% of the lesions, including 9 carcinoid tumors (33%), 2 mucoepidermoid tumors, 2 fibrous histiocytomas, 1 hemangiopericytoma, and 1 large cell carcinoma. Scarring and stenosis secondary to multiple causes occurred in 10 patients (37%). Two patients had miscellaneous lesions. Presenting symptoms included dyspnea (52%), wheezing or stridor (44%), cough (41%), hemoptysis (37%), and pneumonia (18%). Preoperative chest roentgenogram was abnormal in 60% of patients, whereas tomograms delineated the lesion in 94%. All patients had bronchoscopy for lesion evaluation. Anesthesia was accomplished through a long single-lumen endotracheal tube in 19 cases and a double-lumen tube in 8 cases. Mobilization and exposure techniques to create a tension-free anastomosis were critical for left main bronchial resections and included pretracheal mobilization (100%), neck flexion (100%), tracheal and main bronchial retraction (85%), aortic and pulmonary artery retraction (44%), and intrapericardial hilar release (33%). All resections were for cure; there was no operative mortality. Morbidity in 4 patients (15%) included an anastomotic stenosis (successfully reresected), prolonged air leak and pneumonia, transient recurrent nerve palsy, and atelectasis. Median 5-year follow-up revealed 92% of patients alive, with only one of two late deaths being disease-related. Main bronchial resection is an ideal technique for selected benign and malignant lesions, allowing complete pulmonary parenchymal preservation.

Ambulatory facilities are being used more and more for various diagnostic and therapeutic procedures. We report 183 consecutive mediastinoscopies and/or anterior mediastinotomies performed in an ambulatory setting from July 1981 to January 1991. There were 140 patients with a neoplasia: 131 bronchogenic carcinomas, 5 lymphomas, 2 carcinoid tumors, 1 teratocarcinoma, 1 carcinoma of the stomach. Forty-three patients had a benign condition, including 32 sarcoidosis and 11 miscellaneous diseases. Twenty-eight (15%) patients were admitted the same day: 12 for elective surgery in view of bed availability, 9 for medical observation, and 7 required overnight admission for non-medical reasons. Eight non-fatal complications were encountered: hemoptysis (2), atrial fibrillation (1), pneumonia (1), mediastinal self-contained bleed (1), tear of a pulmonary artery (1), temporary palsy of the recurrent laryngeal nerve (1) and wound infection (1). There was no operative mortality. Overall, ambulatory mediastinoscopy and anterior mediastinotomy permitted a diagnosis in 58 patients (29%), and confirmed unresectable malignant disease in 36 patients, thus sparing unnecessary admission to a surgical ward in 89 (49%) of the 183 patients. Mediastinoscopy and anterior mediastinotomy are safe in an ambulatory setting and alleviate the need for hospitalization in a substantial number of patients.

There are four major prophylactic indications in thoracic surgery: (1) Intra-pulmonary coin lesions with malignancy up to 50% and other potentially malignant tumors (carcinoid tumor, cylindroma, mucoepidermoid tumor, papilloma); (2) mediastinal tumors with potentially malignant growth (teratoma); (3) chronic lung infections including tuberculosis (bronchiectasis, abscess, chronic pneumonia, persistent tuberculoma, tuberculous cavity, destroyed lobe/lung); (4) cystic pulmonary disease followed by frequent complications (infection, bleeding, pneumothorax).

Reported is a rare case of a multiple peripheral pulmonary carcinoids showing a diffuse lung disease synchronously associated with a sigmoid colon cancer. An abnormal chest shadow was detected in a 75-year-old male by X ray during a periodic health examination. After admission to hospital for a more thorough examination he was found to have a sigmoid colon cancer. A CT scan of his chest suggested sarcoidosis, but the results of a bronchofiberscopic examination appeared normal. Subsequently, a TBLB specimen revealed typical carcinoid tumors. Thus, the diagnosis of diffuse multiple peripheral carcinoids was made. A surgical resection of the sigmoid colon cancer was performed successfully, but five months later, the patient died of acute pneumonia. An autopsy was not permitted. Also discussed are multiple pulmonary carcinoids and a double cancer.

A 36-year-old patient developed marked pigmentation, marked myopathy and severe hypokalaemic alkalosis which at first pointed towards an ectopic ACTH syndrome. The dexamethasone test at a high dose indicated cortisol suppression. A mediastinal tumour was seen radiologically, but the sella was of normal size. Computed tomography provided indirect signs of a sellar space-occupying lesion which suggested an ectopic production of corticotropin-releasing factor (CRF) as cause of the Cushing's syndrome. CRF concentration in antecubital venous blood was markedly elevated to 280 ng/l. The mediastinal tumour was excised and proved to be a carcinoid histologically. Postoperatively the CRF concentration fell to 70 ng/l. An extract of the carcinoid contained 15.5 ng/g wet-weight of CRF and 254 ng/g wet-weight of beta-endorphin. The patient died 5 weeks postoperatively of sepsis with bilateral pneumonia. At autopsy the hypophysis was of normal size but showed nodular ACTH-cell hyperplasia. This was thus a case of Cushing's syndrome resulting from ectopic CRF production in a mediastinal carcinoid tumour.

To establish whether bronchoplastic procedures designed to minimize loss of lung tissue are justifiable for the treatment of bronchial carcinoid tumours, data were analysed from 37 patients (17 men, 20 women, average age 51 [22-70] years) who had undergone surgery for typical (n = 30) or atypical (n = 7) bronchial carcinoids. Conventional tumour resections had been performed in 29 cases and bronchoplastic operations in eight. After an average observation period of 54 months one patient who had undergone lobectomy for a bronchial carcinoid had died of recurrent tumour, and one other patient who had been treated by pneumonectomy for an atypical carcinoid had developed distant metastases. All the other patients were free from tumour at that time. This indicates that patients treated by bronchoplastic procedures do not have any higher incidence of recurrences or any lower chance of survival than those treated by lobectomy or pneumonectomy. A bronchoplastic operation should therefore be the treatment of first choice, provided that the adjacent lung tissue has not been destroyed by retention pneumonia and that lymph node dissection does not reveal any involvement.

Twelve patients with a bronchial carcinoid tumor seen over the past 10 years, were retrospectively analyzed. The age, symptoms, smoking habit, previous respiratory conditions, X-ray and extension of the tumor, bronchial endoscopy, treatment and survival were studied. The mean age of these patients was 42.5 years with a male predominance of 2:1. More than half of the patients were smokers (58.3%). The most common symptoms were hemoptysis, costal pain, pneumonia and fever. Two of the patients were asymptomatic (16.6%) and their tumor was detected in a routine health control. Almost half of the patients (41.6%) complained of respiratory symptoms for 3 years previous to diagnosis (mean 7.8 years with a range of 3 to 11 years). 75% of the cases were centrally located. The left lung was most frequently affected (75%). Fiberbronchoscopy was carried out in nine patients; in eight of them the tumor was localized and information was obtained about the segment involved. However, the biopsy was positive in only one case (14.2%). Two patients presented endocrine symptoms with a syndrome similar to the carcinoid. The disease was disseminated with adrenal metastasis in two cases, one of which had also bone and liver metastasis. An immunohistochemical study was performed in eight cases with a positive result for ACTH and calcitonin in one patient. Ten patients were treated with surgery; one with chemotherapy and the other was treated with palliation. Two patients were lost in the follow up period.(ABSTRACT TRUNCATED AT 250 WORDS)
