Six hundred patients underwent diagnostic flexible fiberoptic bronchoscopy (FFB). The two diseases most frequently encountered were bronchogenic carcinoma in 330 patients (55 percent) and bacterial infection in 94 (16 percent). A positive cytology on biopsy material was obtained in 279 of 330 patients (85 percent) with primary lung cancer. Fluoroscopy was a valuable aid in diagnosing bronchogenic carcinoma, since 42 percent of the tumors were not visible endoscopically and required fluoroscopic control for placement of the biopsy instrument. Of the 55 patients with hemoptysis and negative chest x-ray films, nine (15 percent) had fiberoptically visible endobronchial carcinomas! In addition, two patients with carcinoma of the larynx and one with carcinoma of the nasopharynx were discovered. Transbronchial biopsy (TBB) in 68 patinets with diffuse and localized disease achieved an overall 69 percent diagnostic success, including a correct diagnosis in each of four patients with Pneumocystis carinii pneumonia. Brush biopsy provided additional valuable laboratory data in bacterial, mycobacterial and cytomegalovirsu infectious but had a poor yield in Pneumocystis infection. Complications as a result of forceps biopsy were minimal, except for brisk bleeding in six patients.

In a prospective study of 6,027 older men screened every six months for ten years by means of chest photofluorograms and questionnaires regarding symptoms, 121 developed lung cancer after the first examination. Eighty-five men with lung cancer had the opportunity to be screened eight times before the tumor was detected by chest x-ray film, but only 33 actually reported that often. These 33 men were compared with matched controls for symptoms before the neoplasm was detected radiologically. The common symptoms of expectoration and chronic cough showed a significant increase in frequency over time in the cases of cancer, while only expectoration showed a slight increase in the controls. Uncommon symptoms more suggestive of lung cancer (hemoptysis and worsening cough) occurred in only four men prior to detection of cancer. Symptoms are seldom useful in the detection of occult lung cancer, but the appearance of expectoration and chronic cough in older male smokers should raise a suspicion of this disease.

We studied 18 patients, 9 women and 9 men, ranging in age from 18 to 76 years. The main symptom was hemoptysis and the underlying pathology was tuberculosis, actinomycosis, lung cancer, metastatic carcinoma and systemic lupus. Nonsurgical patients, with recurrent hemoptysis or massive bleeding were selected. The embolization substances were spongostan, avitene (R) and PVA; they all produce temporary as well as persistent hemostasis. The procedure was successful in 16 patients. In two patients the embolization was not performed, one for technical reasons and the other because the vessel to be treated was the source of an anterior spinal artery. It is considered that the endovascular treatment constitutes an alternative for hemoptysis, even during the acute period, mainly in the management of nonsurgical patients.

Although blastomycosis is prevalent in the North American continent, it occurs only sporadically in Africa. We describe a 42 yr old patient who complained of intermittent cough and haemoptysis. Clinical findings were strongly suggestive of lung cancer. The diagnosis of pulmonary blastomycosis was made at thoracotomy. This rather unusual disease in our areas caused a considerable delay in securing the diagnosis and we suggest that this infection may be found elsewhere in Africa and the distribution may be wider than has previously been suspected.

20 cases of tuberculosis in the superior segment of the lower lobe of the lung were misdiagnosed as lung cancer, pneumonia, bronchiectasis and inflammatory pseudoneoplasm were reported. The final diagnosis were confirmed by fiberoptic bronchoscopy (FOB). The causes of the misdiagnoses were: (1) the hilar mass shadow found on the PA chest film, mistaken for central type lung cancer; (2) the mass shadow found on the lateral chest film, mistaken for peripheral lung cancer; (3) the patients with fever, cough and expectoration accompanied by exudative infiltrative shadow, mistaken for pneumonia; (4) patients with recurrent attacks of hemoptysis but the lesions overshadowed by the spinal column on the lateral chest film were misdiagnosed as bronchiectasis. The author suggested PA and lateral chest films taken simultaneously were needed. The special points, to which should be pay attention during reading the films were listed and noted. FOB examination including TBLB, brushing and BALF for pathologic and AFB determination could be of help to confirm the 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.

YAG laser treatment was conducted in 55 patients with central airway lesions over the last 8 years. The malignant lesions comprised 1 primary tracheal cancer, 1 chondroma of the trachea, 34 primary lung cancer, and 10 metastatic lung tumor. The benign lesions comprised one each of hamartoma, lipoma, bronchial lithiasis, post-tracheotomy granuloma, and bronchial web, and 3 other cases. Nd-YAG laser treatment was performed in 55 patients with airway lesions, with a success rate of 73%. The success rates in the above patients were 70% for primary lung cancer, 60% for metastatic lung tumor, 100% for primary tracheal cancer and chondroma of trachea, and 89% for benign lesions. In 34 patients with primary lung cancer, palliative widening of the airway was planned with the exception of 2 patients with endoscopically early lung cancer for whom curative vaporization was intended, 6 months-survival rate was 59.3% in patients in whom various combined treatments were performed after the laser treatment. For all patients with hamartoma or lipoma in those with benign lesions, curative vaporization was performed. The severe complication of lethal massive hemoptysis occurred in 3 patients. We consider that Nd-YAG laser treatment is a powerful therapeutic means of performing lifesaving or emergency, curative, and supplemental treatment.

Between November 1988 and March 1990, 24 patients with endobronchial tumors that had recurred after external beam radiation therapy were treated with high dose rate intraluminal irradiation. A remote afterloading high dose rate unit was used, and most patients received two endobronchial treatments, separated by a two week interval. All patients were given the same dose and dose specification to assess the feasibility and complications of the therapy. At each treatment, 15 Gy were delivered with dose specified at a radius of 6 mm from the center of the source, which corresponds to a dose of 9 Gy at a radius of 1 cm. Overall, 21 of 24 patients (88%) showed good symptomatic improvement. Of 18 patients whose chest x-ray showed evidence of collapse or atelectasis caused by tumor obstruction, 15 (83%) had evidence of reaeration. The median duration of palliation, marked by symptoms or a chest x-ray that worsened, was 26 weeks, the range varying from seven to 40 weeks. No patient died as a result of therapy and only one had a complication, bronchospasm, which responded well to bronchodilators. One patient died of hemoptysis approximately three months after treatment. Five additional patients, who were treated off protocol because they had an Eastern Cooperative Oncology Group performance status of greater than two, also received endobronchial irradiation. All five died within one month from worsening pulmonary disease, and we do not recommend endobronchial irradiation for patients with an Eastern Cooperative Oncology Group performance status of greater than two. We conclude that high dose rate endobronchial brachytherapy effectively relieves the symptoms of endobronchial obstruction due to recurrent lung cancer and can be given safely as an outpatient procedure. As the complications were minimal in this series treated with a uniform dose of 15 Gy per treatment, future studies should aim at determining the maximum tolerated dose. This technique may also be helpful as a boost after maximal external beam irradiation or to open up areas of atelectasis prior to external beam irradiation.

A 62-year-old male was admitted with abnormal shadow in chest X-P. CT and other examinations were done, and he was diagnosed left renal cell carcinoma with metastatic lung cancer. He rejected operation and was discharged. We gave him alpha-interferon injection every day. About 5 months later, he complained of fever and dyspnea, and was admitted. On the 10th day after admission, he died suddenly with massive hemoptysis. This hemoptysis was from the pulmonary artery, which was surrounded by tumors and ruptured into the trachea. Pathological diagnosis was double cancer, such a case is very rare with a primary lung cancer (oat cell carcinoma) which has metastasized into a renal cell carcinoma (common type, clear cell subtype).

Thirty-eight neodymium yttrium aluminium garnet (Nd-YAG) laser sessions have been performed in 26 patients under local anaesthesia. The majority of patients had recurrences of inoperable non-small-cell lung cancer after radiotherapy. At evaluation, a subjective improvement of dyspnoea was noticed in 70% (18/26) of the patients, and in 54% (14/26) of the cases, a greater than 50% improvement of the airway lumen diameter was assessed at bronchoscopy. Haemoptysis subsided in 4 out of the 5 patients. On 2 occasions, the rigid scope was introduced to provide optimal control of minor bleeding during the laser performance. Neither respiratory failure, nor any treatment-related death has occurred. In our hands, Nd-YAG treatment under local anaesthesia was a feasible, effective and safe procedure.
