Thirteen cases of primary thymic carcinomas are described. The patients' ages ranged from 19 to 64 years, with a median of 40 years. Nine of them were male. Chest pain with or without cough was the main presenting symptom. No patient had myasthenia gravis. Five histological types were identified; two were undifferentiated (lymphoepithelioma-like) carcinoma, one was a clear-cell carcinoma, two were mixed squamous and small-cell carcinoma, and six were squamous cell carcinoma. All the tumors were variably positive for anti-keratin antibody AE1 and AE3, but negative for AE2. Anti-neuron specific enolase antibody was useful in identifying and confirming the small-cell carcinoma component of the mixed carcinomas. Anti-epithelial membrane antigen antibody aided in revealing the glandular structures in mixed adenosquamous and small-cell carcinomas. Thymic carcinomas were histopathologically differentiated from thymomas by their malignant cytological appearance, increased mitotic activity, and central tumor necrosis. All six patients with pure squamous-cell carcinoma were still alive, with a median survival time of 27 months. All but one of the other patients of different histological types died, the exception being a recent case of mixed adenosquamous and small-cell carcinoma; their median survival was 19.5 months, or 18 months when the latter surviving case is included. The prognosis of patients with pure squamous-cell carcinoma was better.

The voluntary cough sounds recorded according to Korpas and Sadlonova-Korpasova were sampled at a frequency of 20.000Hz and spectra of six consecutive windows of 50ms were estimated. To digitize signals an autotrigger mode was used. The subjects were healthy volunteers as well as patients with chronic bronchitis, asthma, bronchial carcinoma (growing intraluminarly in the 1st or in the 2nd or in the 3rd order bronchi), emphysema, laryngeal nerve paralyzis or laryngotomy. The duration of averaged cough sounds of patients was longer than that of healthy volunteers. The mean power of the spectra in the successive windows showed different patterns in the same group. In the third window of healthy volunteers (0.10 s-0.15 s) a high modulus broad bandwidth (between 1-2 kHz) spectrum was found which was considered as a bronchial "flute", and was probably related to the lowest resistance as well as to the velocity of airflow of cough manoeuvre. This pattern appeared with a delay and/or it was changed in the diseased groups compared to the healthy volunteers. Due to this delay, the spectra of the fifth window (0.20 s-0.25 s) showed somewhat higher harmonics (400-800 Hz) in the patients with chronic obstructive pulmonary diseases (COPD), carcinoma and laryngeal nerve paralyzis than in healthy volunteers. In emphysematous patients in the first (0.00-0.05 s), in the third (0.10-0.15 s) and in the fifth (0.20-0.25 s) windows the fundamental frequency was low (156-176 Hz) compared to that of the other groups. The paralyzed vocal cords functioning as an added resistance to the expiratory effort caused a phase-shift in the cough patterns, similarly to that seen in COPD patients. Due to the cannula, the spectra of patients having laryngotomy had a lot of high harmonics. They also had peaks nearly identical to that of bronchitic patients because they suffered from serious chronic bronchitis. It was found that by examination the cough spectra of series of voluntary cough sound signals it was possible to distinguish healthy volunteers from patients. This examination would therefore be useful for screening of bronchial diseases.

Fifty-four cases (55 foci) of primary tracheal malignancies were reviewed retrospectively. Radiologic material was available in 32 cases (33 tracheal foci). The most frequent primary malignant tumor of the trachea was squamous cell carcinoma (54.5%), followed by adenoid cystic carcinoma (18%) and adenocarcinoma (9%). The radiologic appearance of the tumors could be divided into intraluminal, wall-thickening, and exophytic forms. Wall-thickening and exophytic forms in this study accounted for 62% of the tumors. This indicates that malignant tumors of the trachea tend to extraluminal invasion. Tomography and computed tomography are the most helpful methods of radiologic examination for tracheal tumors. Bronchoscopy and radiologic examination are complementary procedures. The chief advantage of imaging is the demonstration of tracheal wall thickening and extraluminal changes. Hemoptysis, dyspnea, and cough were the most common symptoms. Four cases (7%) in our series presented as thyroid tumors due to direct extension into the thyroid gland. Fifteen of the 54 cases (28%) were associated with other carcinomas of the head and neck and the lung.

Fifty-three patients with recurrent and advanced stage (III and IV) non-small-cell lung cancer (NSCLC) were treated with a combination of bleomycin, etoposide (VP-16-213), and cis-diamminedichloroplatinum (BEP). Forty-eight patients were appraisable for response. The response rates were 44% for the entire group, 57% in 30 patients with combined squamous-cell and large-cell carcinoma, and 22% in 18 patients with adenocarcinoma (40%, 50%, and 19%, respectively, if patients not appraisable for response are included as nonresponders). The median survival time of patients with squamous-cell and large-cell carcinoma was slightly longer than that of patients with adenocarcinoma (23 weeks v 19 weeks). Patients with responsive disease survived significantly longer (median, 34 weeks) than did patients with unresponsive disease (median, 16 weeks) (P = .001). In the entire group, the median survival time of patients with an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 was better (23 weeks) than of those with a status of 2 or 3 (15 weeks), but this difference was not seen in the subgroup with squamous-cell and large-cell carcinoma (24 weeks v 23 weeks, respectively). Thus, the performance status was not of prognostic value in the histologic subgroups experiencing the best response rate. There were two treatment-related deaths, but otherwise the toxicity of BEP was acceptable. Only four of the 119 treatment cycles were followed by fever even though there was significant neutropenia (0.5 X 10(9)/L) after 20 of 97 treatment cycles. The majority of patients receiving BEP experienced relief of cough, hemoptysis, pain, and fatigue associated with their disease. There was a good correlation between objective responses and palliation of symptoms. Thus, BEP offers good palliation, particularly for patients with squamous-cell and large-cell lung cancer.

Palliative therapy for previously irradiated patients with symptomatic recurrent endobronchial malignancy is a difficult problem. We have had the opportunity to treat 20 such patients with high dose rate (50-100 rad/min) endobronchial brachytherapy. Eligible patients had received previous high dose thoracic irradiation (TDF greater than or equal to 90), a performance status of greater than or equal to 50, and symptoms caused by a bronchoscopically defined and implantable lesion. The radiation is produced by a small cobalt-60 source (0.7 Ci) remotely afterloaded by cable control. The source is fed into a 4 mm diameter catheter which is placed with bronchoscopic guidance; it may oscillate if necessary to cover the lesion. A dose of 1,000 rad at 1 cm from the source is delivered. We have performed 22 procedures in 20 patients, four following YAG laser debulking. Most had cough, some with hemoptysis. Eight had dyspnea secondary to obstruction and three had obstructive pneumonitis. In 12, symptoms recurred with a mean time to recurrence of 4.3 months (range 1-9 months). Eighteen patients were followed-up and reexamined via bronchoscope 1-2.5 months following the procedure; two were lost to follow-up. All had at least 50 percent clearance of tumor, and six had complete clearance; most regressions were documented on film or videotape. In six, the palliation was durable. The procedure has been well tolerated with no toxicity. We conclude that palliative endobronchial high dose rate brachytherapy is a useful palliative modality in patients with recurrent endobronchial symptomatic carcinoma.

Thirty-nine adults with solid tumors were treated on a Phase I study of menogaril administered i.v. once each week. Granulocytopenia was dose-limiting at a menogaril dose of 115 mg/m2/wk. Ten patients required delays in treatment of 1-4 weeks (median, 1 week) at some point during their treatment until they recovered from granulocytopenia. The average dose intensity possible on this schedule was at least 80% higher than that possible using a single-day or a five-times-daily schedule every 4 weeks. One patient developed infection while neutropenic, and only one patient developed thrombocytopenia. Dexamethasone appeared to reduce the degree of myelosuppression. Gastrointestinal toxicity was quite mild, and alopecia was uncommon. Arm vein phlebitis frequently followed menogaril administration, requiring the use of Hickman catheters (or equivalents). Two patients had myocardial infarcts while on treatment. It was unclear if the menogaril was in any way responsible. Reversible dyspnea and cough (with no evidence of congestive heart failure) were seen in some patients. Responses were seen in patients with gliomas, renal-cell carcinoma, and bladder carcinoma, and marked subjective improvement occurred in a single patient with prostate cancer. We plan to conduct a Phase II study in astrocytoma patients using a menogaril dose of 115 mg/m2/wk i.v.

Between 1940 and 1985, 24 cases of primary carcinoma of the trachea were registered at the London Regional Cancer Centre. The most common presenting symptoms were hoarseness, haemoptysis and cough. Twenty patients had epidermoid carcinoma and four had adenoid cystic carcinoma. Because of different clinical behaviours, the two histologies were separately analyzed. Of the 20 patients with epidermoid carcinoma, 19 received radiotherapy as primary treatment and one patient did not receive radiotherapy because of advanced disease. Radiation doses ranged from 4000 to 6000 cGy and most patients had megavoltage irradiation. Treatment result was disappointing. Only one patient remained disease-free at 15-month follow-up and all other patients had persistent or recurrent tracheal tumour. Median survival for all 20 patients was 5 months (range 1 to 19 months). Of the four patients with adenoid cystic carcinoma, two had primary surgery and postoperative radiotherapy and two had primary radiotherapy. Two patients died of disease, at 5 months and 8 years from diagnosis. Two surviving patients had 15-month follow-up: one had persistent disease and the other was free from recurrence. In this study, radiotherapy within the range of doses given was found to be an ineffective primary treatment for tracheal carcinoma.

Two hundred ten dogs that had primary lung tumors diagnosed between 1975 and 1985 were evaluated. The majority of the tumors were classified as adenocarcinoma (74.8%) and alveolar carcinoma (20%). The most common clinical signs of disease were cough (52%), dyspnea (23.8%), lethargy (18.1%), weight loss (12.4%), and tachypnea (4.8%). The clinical methods that were most successful in directly or indirectly leading to a diagnosis of primary lung tumor were thoracic radiography (77.1%) and cytologic examination of fine-needle aspirate specimens (24.8%).

Reported are two rare cases of a clinically unknown large cell carcinoma of the lung, associated with severe stenosis of the bilateral main bronchi. Case 1: A 61-year-old man was admitted to our hospital because of chief complaints that included a cough, hemosputum, and dyspnea. Based on the bronchoscopic findings that revealed severe stenosis of the bilateral main bronchi and a specimen that was biopsied from tracheal spur, a diagnosis of large cell carcinoma of the lung was made. Although anticancer chemotherapy and irradiation therapy produced a slight improvement in the patient's symptoms, at the 10th hospital week the patient died of suffocation. Case 2: A 77-year woman was admitted to hospital with chief complaints that included a cough and hemosputum. A bronchoscopy revealed severe stenosis of the bilateral main bronchi. After the 4th hospital day the patient complained of increasing dyspnea. At the 9th hospital day the patient died of suffocation. An autopsy results revealed a large cell carcinoma (giant type) of the lung.

A 36-year-old man was admitted with cough and sputum. He had cafe-au-lait spots and multiple subcutaneous neurofibromas. Chest X-ray revealed multiple emphysematous bullae in bilateral upper lobes and a tumor in the bulla of the right upper lobe. Needle aspiration biopsy of the tumor showed small cell carcinoma. Although chemotherapy and radiation resulted in decrease in tumor size, it subsequently increased in size and he died 11 months after admission. Including this case there have been 7 reports of Recklinghausen's disease associated with multiple lung cysts and 8 reports with lung cancer in Japan. However, cases with lung cysts and cancer are very rare. The cancer of this case was considered to be associated with emphysematous bulla rather than Recklinghausen's diseases.
