Tracheal or endobronchial metastases from distant primary malignancies are rare. Hemoptysis, dyspnea and cough are common nonspecific presenting symptoms. Renal, breast, thyroid and colon cancers are the most common malignancies associated with tracheobronchial metastases. Since 1979, five patients with tracheobronchial metastases from distant sites have been treated by the otolaryngology service at the Boston University Medical Center. Patients with advanced tumors previously treated by conventional modalities were referred for palliation of airway obstruction. Satisfactory palliation without significant morbidity was achieved in four out of five patients utilizing a CO2 surgical laser through a rigid bronchoscope system. Four patients died from advanced cancer, 1 to 18 months after laser surgery. Although tracheobronchial metastasis from extrathoracic malignancy is associated with a poor prognosis, palliation of airway obstruction can be achieved in most patients with endobronchial or tracheal tumor.

Lymphangitic carcinomatosis is usually a late manifestation of metastatic disease. The patient usually presents with cough or dyspnea, and the chest radiograph is often nondiagnostic. Two patients are presented who developed symptoms while on adjuvant chemotherapy. Both had abnormal perfusion lung scans. One had matching ventilation defects; the other a normal ventilation study. Biopsy revealed metastatic carcinoma; in one case tumor was seen in both the pulmonary lymphatics and arterioles; in technique which can speed diagnosis and institution of therapy in lymphangitic carcinomatosis.

An analysis is made of the contribution of clinical examination to the diagnosis of primary bronchopulmonary cancer in a lot of 355 patients. As it is known bronchopulmonary cancer does not have a characteristic and patognomonic clinical symptomatology. In two thirds of the patients (236/66.4%) the disease' onset was marked by respiratory symptoms. In half of these patients (120/33.8% of the total number of cases) the respiratory syndromes for which the patient had requested medical help could have suggested the diagnosis, and were marked by a pseudo-pneumonia, or pneumopathy with long evolution, intensified coughing in a patient who had been coughing for a long time, or an onset marked by hemopthysis. In the other half of the patients in this group the onset symptoms had nothing characteristic. The onset marked by metastases was noted 69 of the patients (19.4%), and para-neoplastic syndromes were noted in 10 (2.8%). These certainly suggested the presence of pulmonary cancer. It appears that in over half of the patients 9195, or 54.1%) the clinical examination could suggest the existence of bronchopulmonary cancer, and this percentage increases if patients are included in those whose respiratory symptoms are not characteristic but in those which physical examination will evidence suggestive changes. Only in a very small number of patients (12, or 3.3%) the clinical examination did not provide any diagnostic element. These were the asymptomatic cases, accidentally identified in the course of a radiological examination. It should be stressed that the clinical suspicion of pulmonary cancer should always be confirmed by paraclinical investigations.

Chemotherapy-related pneumonitis developed in eight patients during treatment for breast cancer. Six were receiving adjuvant therapy and two were being treated for metastatic disease. Fever, chills, dyspnea, and dry cough were the initial symptoms. Observations from chest roentgenograms varied from normal to bilateral interstitial-alveolar infiltrates. Results of pulmonary function tests were markedly abnormal, with a decreased diffusing capacity being the most characteristic abnormality. The pneumonitis developed in six patients while receiving 20 mg or less per day of prednisone and appeared temporarily related to tapering of steroid therapy in four patients. All patients recovered clinically, although prednisone therapy of 60 mg/day or its equivalent was required in three cases. Mild pulmonary function abnormalities persisted. Drug-induced pneumonitis should be considered in the differential diagnoses of patients with breast cancer in whom unexplained fever, dyspnea, or infiltrates develop during multidrug chemotherapy.

The case is reported of a 26-year-old patient hospitalized after 6 days of coughing and dyspnea with the clinical picture of "adult respiratory distress syndrome" (ARDS). In spite of intensive therapeutic efforts, death ensued within a few weeks. Autopsy revealed widespread intraalveolar metastases of a hitherto unrecognized amelanotic malignant melanoma of the back. Further metastases were only detected in intrathoracic lymph nodes and in the myocardium. A possible relationship between this unusual pattern of metastasis and previous abuse of nicotine, alcohol and hashish, as well as coexisting hypogammaglobulinemia, is discussed. It appears that widespread intrapulmonary metastasis must be considered one of the possible causes of ARDS.

Twelve cases of interstitial pneumonitis were seen in 50 patients (24%) treated with cyclophosphamide, methotrexate, and etoposide (VP-16-213) for small cell anaplastic lung cancer. The clinical course and pathologic characteristics were consistent with drug-induced pneumonitis in all 12 cases. One additional patient had concurrent histologic evidence of interstitial pneumonitis, pneumocystis infection, and perivascular metastases. Patients presented with severe dyspnea, hypoxemia, cough, fever, and bilateral interstitial infiltrates on chest films. The onset was rapid and unpredictable, following as little as one month or as much as five months of therapy. Nine patients recovered but there were three deaths in the acute period directly attributable to the drug-induced pneumonitis. Although the use of twice weekly oral methotrexate may have been a causative factor, a previously unsuspected drug interaction with etoposide may be the etiologic factor resulting in this unusually high incidence of pulmonary toxicity. The difficulty in establishing a diagnosis of interstitial pneumonitis in this group of patients with chronic lung disease and lung cancer is well known. The extent of morbidity and mortality seen in this study and the commercial availability of etoposide make earlier clinical recognition of this complication imperative.

Thirty-two patients with peripheral bronchogenic neoplasms adherent to the chest wall underwent en bloc pulmonary and thoracic wall resections. Presenting symptoms were thoracic wall pain (75 percent), hemoptysis (12.5 percent), and cough with weight loss (12.5 percent). Patients were selected for surgical resection only after a search for metastatic disease, including mediastinoscopy, showed negative results. A standard posterolateral thoracotomy incision was used which did not require skeletal reconstruction or prosthetic material for closure. There were nine major postoperative complications (28.8 percent), principally respiratory, and one operative death (3.1 percent). The five-year actuarial survival was 35 percent. None of the patients with regional lymph node involvement or positive chest wall margins lived more than two years after surgery. Preoperative irradiation performed in 12 patients (37.5 percent) improved operability, but did not significantly alter survival. These results indicate that patients with peripheral bronchogenic carcinoma involving the thoracic wall may be successfully managed with en bloc pulmonary and chest wall resection, particularly if surgery is performed in the early stage of the disease.

Fifty-three patients underwent 55 post-thoracotomy bupivacaine epidural analgesia experiences for pain control. Hospital records of all patients were analyzed for effectiveness of pain relief, changes in vital signs, and complications. In most instances, pain relief was adequate and patients were able to move, cough, and deep breathe unusually well in the postoperative period. Correlations were tested among changes in blood pressure, pulse, respiration, the actual value for low blood pressure, and subsequent elevation, age, sex, thoracotomy side, primary diagnoses, a secondary diagnoses, metastases, and complications. Systolic blood pressure reduction was greater in older patients who received epidural bupivacaine, with a correlation coefficient which attained significance (p less than 0.04). Patients who underwent thoracotomies for chronic pulmonary inflammation (p less than 0.04) or patients who had previous myocardial infarctions (p less than 0.05) also demonstrated significant reduction in systolic blood pressure. However, the number of patients in each group (six and four, respectively) makes their significance questionable. Although there were no serious complications or deaths attributable to this technique of pain control, possible morbidity is discussed. Removal of the epidural catheters was without incident. There was no evidence of irritation, pain, or infection at the catheter placement sites.

Several types of neoplastic conditions are included in the differential diagnosis of pneumonia. Bronchial obstruction with cancer can produce obstructive pneumonia that results in intractable infection. Bronchogenic carcinoma and metastatic cancer involving the airways may produce this clinical presentation. Bronchioloalveolar carcinoma is a relatively common form of primary lung cancer that characteristically presents as a chronic infiltrate associated with cough, hypoxemia, shortness of breath, and mucus hypersecretion. This cancer has two distinct histological types with markedly different prognosis. The mucinous variety is much more likely to be multicentric and rapidly progressive whereas the nonmucinous variety may be localized. Lymphoproliferative diseases may also present in an infiltrative appearance. Kaposi's sarcoma infiltrating the lungs, particularly associated with acquired immune deficiency syndrome, presents a diagnostic dilemma because of the high incidence of pulmonary infection in these patients.

A policy of palliative intent thoracic irradiation was prospectively evaluated in 38 consecutive patients referred for treatment of inoperable non-small cell lung cancer at a single institution. A target dose of 1700 cGy in two fractions 1 week apart was delivered. Characteristics of the treatment group revealed most (87%; 33/38) to be of good-excellent performance status with minimal weight loss before irradiation. Although three patients (8%) had initial metastatic disease, all had symptoms referable to the thorax with cough (71%), dyspnoea (55%), haemoptysis (39%), and chest wall pain (34%) being dominant. Following treatment, the relative risk of maintaining complete response with regard to each of these symptoms was 0.91, 0.40, 0.92 and 0.78, respectively. Overall 70% of patients maintained complete symptomatic response to time of death or last review. Uncorrected median survival was 35 weeks and was comparable to best international end-results for either palliative intent or curative intent radiation schedules. We conclude that the radiation regimen employed is safe, efficacious and eminently resource conscious. Recognition of patient groups who overwhelmingly derive no benefit from conventional fractionation schedules will streamline access to radiotherapy services of patients suitable for radical treatment.
