A total of seven patients with bronchial carcinoids were treated at our hospital during the period from 1975 to 1991. Debut of symptoms varied from eight months to ten years before diagnosis. Cough, copious mucus, hemoptysis and recurrent lobar pneumonias were common. Six tumours were identified by chest X-ray. All tumours were visualised bronchoscopically; five showed as cherry-red polypoid tumours, one as a necrotising tumour and one as a stenosis of the bronchus. One patient underwent pneumonectomy, three lobectomy, one bilobectomy, one segment resection and one sleeve resection and lobectomy combined. Two cases were complicated by empyema and one was not radically operated due to impaired cardiopulmonary function. None showed carcinoid syndrome. All patients are still alive, and no recurrences or metastases have appeared.

We report a case of primary diffuse tracheobronchial amyloidosis in a 72-year-old lady who presented with a long history of recurrent cough, dyspnoea, wheezing, haemoptysis and chest infection. She was treated successfully with three sessions of laser therapy. There were improvements in both clinical symptoms and measurements of airway obstruction. Bronchodilators and oral prednisolone were not required after treatment.

A case of glomus tumour of the trachea is reported. The patient, a 58-year-old man, complained of dyspnoea, cough and occasional haemoptysis for many years and had been misdiagnosed as having chronic bronchitis. The diagnosis of glomus tumour in a tissue sample taken by bronchoscopy was useful in planning adequate surgery. Light and electromicroscopy of the excised tumour confirmed the preoperative diagnosis. Immunohistochemical examination showed vimentin and actin in the tumour cells, and negativity for high and low molecular weight keratins, desmin, neurofilaments, and factor VIII-related antigen, findings similar to glomus tumours of other sites.

Flexible Nd:YAG endoscopic laser surgery may become an effective new modality for palliation in patients with obstructive endotracheal metastatic malignancies. We report the results of the treatment of two patients with severely obstructing intraluminal tracheal metastatic melanoma and medullary thyroid carcinoma, using the neodymium-YAG laser via the flexible fiberoptic bronchoscope. Both patients complained of significant dyspnea, orthopnea, cough, and hemoptysis and were not candidates for rigid bronchoscopy because of underlying medical contraindications and anatomical problems. Multiple treatment sessions were used with treatment intervals of 1 to 2 weeks. All treatments were performed in the operating room under sedation, without intubation, with topical lidocaine and standard superior laryngeal nerve block. Successful relief of airway obstruction with complete regression of the endotracheal masses was achieved and no recurrences were seen after 9 months' follow-up. Flexible Nd:YAG laser bronchoscopy offered an alternative for the relief of obstructing endotracheal or bronchial malignancies in patients in whom the rigid bronchoscope could not be passed. it seemed to prolong survival in selected cases, and provided definite improvement in quality of life.

Fifty patients with inoperable, symptomatic endobronchial carcinoma were treated by a single exposure of intraluminal radiotherapy. A high dose rate afterloading system (the micro-Selectron-HDR) was used to minimise radiation exposure for staff. Haemoptysis was relieved in 24 of 28 patients, breathlessness in 21 of 33 patients, and cough in nine of 18 patients. Radiological collapse resolved in 11 of 24 patients. Treatment was given on an outpatient basis and was well tolerated. Intraluminal radiotherapy appears to offer an effective alternative to conventional fractionated external beam radiotherapy.

We have reviewed the role of radiation therapy in the palliative treatment of patients with non-small cell lung cancer. The use of radiation treatment results in effective palliation of chest symptoms such as dyspnea, cough, hemoptysis, and chest pain. In addition, the pain and suffering associated with skeletal and hepatic metastases are effectively alleviated by radiation therapy with minimal morbidity. Devastating neurologic complications can be avoided or alleviated in a great proportion of patients undergoing radiation therapy for cerebral metastases and spinal cord compression. Therefore, radiation therapy is a potent modality in relieving or reducing the suffering of patients with lung cancer. This is also a modality that has wide applicability; very few patients are not suitable candidates for that has wide applicability; very few patients are not suitable candidates for treatment regardless of their performance status. The aim of the treatments should always be prompt intervention using radiation therapy schedules that will minimize treatment time yet produce the desired results in a high proportion of patients. Protracted radiation schedules are not warranted in such patients except in special clinical situations. Palliation with radiation therapy is achieved quite promptly, with minimal side effects and a very small risk of any long-term consequences in patients who have a limited life expectancy.

Two policies of palliative thoracic radiotherapy for non-small-cell lung cancer have been compared in a randomised multicentre controlled trial. A total of 369 patients with inoperable, histologically or cytologically confirmed disease, too advanced for radical 'curative' radiotherapy, and with their main symptoms related to the primary intrathoracic tumour even if metastases were present, were studied. They were allocated at random either to a regimen of 17 Gy given in two fractions of 8.5 Gy 1 week apart (F2 regimen), or to a conventional multifractionated regimen of either 30 Gy in ten fractions or 27 Gy in six fractions (a biologically equivalent dose), given daily except at weekends (FM regimen). On admission, 93% of the patients had cough, 47% haemoptysis, 57% chest pain, 58% anorexia, and 11% dysphagia. As assessed by the clinicians, palliation of the main symptoms was achieved in high proportions of patients ranging in the F2 group from 65% for cough to 81% for haemoptysis and in the FM group from 56% for cough to 86% for haemoptysis. Haemoptysis, chest pain, and anorexia disappeared for a time in well over half the patients with these symptoms, and cough in 37%. For all the main symptoms, the median duration of palliation was 50% or more of survival. Performance status improved in approximately half of the patients with a poor status on admission. All these results were similar in the two treatment groups. As assessed daily by the patients using a diary card, the quality of life deteriorated slightly during treatment but then improved steadily during the next 5 weeks. The proportion of patients with dysphagia increased considerably during treatment, but fell to the pretreatment level during the next 2 weeks. The results were similar in the two groups. Radiation myelopathy was suspected in one (F2) patient. There was no difference in survival between the two groups (log-rank test), the median survival time from the date of allocation being 179 days in the F2 and 177 days in the FM group. In the light of all the findings, the regimen of two fractions of 8.5 Gy given 1 week apart is recommended.

Thirty-eight patients were treated with high dose rate endobronchial brachytherapy to palliate symptoms (cough, hemoptysis, fever, and/or shortness of breath) caused by endobronchial of previously irradiated (greater than or equal to 5000 cGy) bronchogenic carcinoma. The dose per fraction was 600 cGy at a radius of 1 cm from the center of the linear path of the source, and each patient received three fraction, each fraction separated by a 1-week interval. Twenty-nine patients (76%) had symptomatic improvement, 16 with complete and 13 with partial relief of symptoms. The likelihood of symptom relief was greater in those patients who had extra-bronchial tumor measuring less than 5 cm (15/15) compared to those with extra-bronchial tumor measuring greater than or equal to 5 cm (2/8). The median duration of symptom relief was 7.5 months. Repeat bronchoscopy done 3 months after brachytherapy revealed that 41% (11/27) had complete tumor regression and another 41% (11/27) had partial regression. Nine of 14 patients with post-obstructive atelectasis/pneumonitis had radiographic improvement. Twelve patients (32%) died from massive hemoptysis occurring 2-56 weeks (median 10 weeks) after brachytherapy. Location of the recurrence was the most important predictor of pulmonary hemorrhage. It occurred only in patients with recurrence in the right upper lobe, right mainstem, or left upper lobe bronchus. Whether this high rate of fatal pulmonary hemorrhage was a real phenomenon or a statistical fluke of small numbers remains an unanswered question.

Oxygen therapy through a transtracheal catheter has been used increasingly for the long-term delivery of continuous oxygen. Compared to nasal cannula it results in significant reduction in oxygen flow requirements. This form of therapy has gained patient acceptance because of several advantages including improved convenience, aesthetics, compliance, and mobility. Reported complications generally have been minor, including subcutaneous emphysema, cough, "mucous ball" formation and mild hemoptysis. In this report, we describe a case of granulation tissue formation at the transtracheal catheter puncture site which was treated with Nd:YAG laser bronchoscopy to reestablish patency of the upper airway. No recurrence was noted after two years of follow-up.

We determined the prevalence of respiratory symptoms and lung dysfunction in a large sample of habitual smokers of freebase cocaine ("crack") alone and in combination with tobacco and/or marijuana. In addition, we compared these findings with those in an age- and race-matched sample of nonusers of crack who did or did not smoke tobacco and/or marijuana. A detailed respiratory and drug use questionnaire and a battery of lung function tests were administered to (1) a convenience sample of 202 habitual smokers of cocaine (cases) who denied intravenous drug abuse and (2) a reference sample of 99 nonusers of cocaine (control subjects). The cocaine smokers (85% black) included the following: 68 never-smokers of marijuana, of whom 43 currently smoked tobacco and 25 did not, and 134 ever-smokers of marijuana (42 current and 92 former), of whom 92 currently smoked tobacco and 42 did not. The control subjects (96% black) included the following: 69 never-smokers of marijuana, of whom 26 currently smoked tobacco and 43 did not, and 30 ever-smokers of marijuana (18 current and 12 former), of whom 21 currently smoked tobacco and 9 did not. Cases smoked an average of 6.5 g cocaine per week for a mean of 53 months. The median time of the most recent use of crack prior to study was 19 days (range less than 1 to 180 days). After controlling for the use of other smoked substances, frequent crack use was associated with: (1) a high prevalence of at least occasional occurrences of acute cardiorespiratory symptoms within 1 to 12 h after smoking cocaine (cough productive of black sputum [43.7%], hemoptysis [5.7%], chest pain [38.5%], usually worse with deep breathing, and cardiac palpitations [52.6%]) and (2) a mild but significant impairment in the diffusing capacity of the lung.(ABSTRACT TRUNCATED AT 250 WORDS)
