A 47-year-old woman was admitted to our hospital for cough and dyspnea. Roentgenologic studies and bronchoscopy revealed multiple lung tumors one of which obstructed the right main bronchus. Right pneumonectomy was performed for the pending obstruction of the trachea. The tumor in the right S1 was found to be protruding into the trachea through the right B1 and the main bronchus in a polypoid fashion. The pathological diagnosis of synovial sarcoma was made on the basis of the characteristic biphasic structure composed of spindle cells and epithelioid cells forming gland-like spaces. Three years and eight months after the pneumonectomy, a nodule in the tendon of the extensor hallucis longus muscle became palpable. It was also a synovial sarcoma pathologically. Synovial sarcoma is a soft tissue sarcoma which usually arises in the extremities. It is very rare for pulmonary metastasis of this tumor to be found while the primary tumor is undetectable.

Tracheobronchial obstruction resulting from esophageal carcinoma is uncommon. Patients with advanced esophageal carcinoma with tracheobronchial obstruction usually present with severe dyspnea or hemoptysis or both and may die of suffocation. The Lahey Clinic experience using laser bronchoscopy for the palliation of symptoms of airway obstruction in patients with esophageal carcinoma is presented. From 1982 to 1990, nine patients were treated in 13 procedures using the neodymium: yttrium-aluminum-garnet laser. Of the patients, seven had undergone previous treatment of the primary tumor. Tumors were located in the trachea in seven patients and in the main stem bronchi in three patients. Improvement of the airway caliber was achieved in all patients with relief of the dyspnea. The mean hospital stay was 2 days. One patient lived 4 years after laser treatment with no recurrence of tumor, and one patient died 1 week after treatment as a result of his poor general condition. The rest of the patients lived 3 to 41 weeks, with a median survival of 35 weeks. No complications were related to the procedures, and in particular, no tracheoesophageal fistulas developed. Our experience indicates that bronchoscopic application of this laser in conjunction with other treatment modalities can improve the quality and duration of life in selected patients with esophageal carcinoma that invades and obstructs the trachea.

This report is an analysis of the medical records of 83 patients registered between 1960 and 1980 at Helsinki University Central Hospital as having malignant pleural mesothelioma. 65 of 83 patients had histologically confirmed malignant mesothelioma, and are the focus of this analysis. The remaining 18 (22%) patients were excluded because malignant mesothelioma was only confirmed cytologically, or because the primary tumor was not a mesothelioma. The ratio of men to women was 2:1.30 of 65 (46%) patients were not known or not likely to have been exposed to asbestos. The main symptoms at presentation were dyspnea, cough, chest pain, fatigue and weight loss. The median survival from diagnosis was 12 months, and from the onset of symptoms 18 months. Clinical stage and performance status were significant prognostic factors. Hematogenous metastases were present at autopsy in most cases. Disease and performance status therefore need to be well established and documented in clinical trials involving mesothelioma.

In a total of 511 patients with T3,N0-3,M0 laryngeal carcinoma, 24 possible prognostic factors were analyzed retrospectively. The factors were age, sex, mode of treatment, duration of several clinical symptoms, the presence of sore throat, otalgia, dyspnea, and dysphagia, previous tracheotomy, tumor extension, lymph node status (five items), histologic grading, smoking habits, and alcohol intake. For 300 patients in whom surgery was part of the primary treatment, pathologic staging of the primary tumor and of lymph nodes in neck dissection specimens, cartilage invasion, radicality of the operation, differentiation grade, and subglottic extension ware also evaluated. In a univariate analysis for the whole group, tumor extension (limited to the glottic region), lymph node status (clinically palpable lymph nodes, cytologically confirmed positive lymph nodes), level of lymph node metastasis (high and midjugular site), histologic grading (poor differentiation grade), and treatment modality (planned combined therapy) were considered to be prognostic factors of corrected actuarial survival. In the group that underwent surgery, all factors derived from specimens of the larynx and neck dissections had prognostic significance. Multivariate analysis revealed that the glottic site of the tumor, the presence of cyto- and histopathologically proven metastatic lymph nodes, pretreatment tracheotomy, positive resection margins, and planned combined treatment had a significant influence on corrected actuarial survival.

There were 79 cases of cardiac tumors seen from 1957 to July 1988. 49 (62.0%) of them were benign and 30 (38.0%) malignant. All the 49 benign tumors except 2 were surgically excised and found to be myxoma. Of them, 18 patients were male and 31 female. 85.7% of the tumors were located in the left atrium, 12.2% in the right atrium and 2.0% in the left ventricle. Palpitation, dyspnea, chest oppression, fever, episodes of syncope and hemiplegia, cough, diastolic and systolic murmurs at the apical or tricuspid area were the common symptoms and signs. Atrial fibrillation was found only in 2 cases. Echocardiographic findings were diagnostic while ECG and X-ray findings were nonspecific. Four patients died after operation. Of the 30 cases of malignant tumors, 15 were secondary tumors metastasized mainly from the lung or mediastinal malignancies. Of 11 primary tumor cases (7 males and 4 females), 3 were malignant lymphoma, 2 mesothelioma of pericardium, 2 malignant myxoma, 1 angiosarcoma, 1 leiomyosarcoma, 1 fibrosarcoma and 1 rhabdomyosarcoma. Another 4 cases were not studied histopathologically. The clinical manifestations, ECG and X-ray findings of the 11 primary tumors were nonspecific but echocardiography was helpful to the diagnosis. Six patients were operated on and 1 died during hospitalization.

A 78-year-old man was admitted to our hospital with dyspnea in June 1988, and diagnosed as having small-cell lung carcinoma by cytological findings of pleural effusion. He was treated three times with CAV (cyclophosphamide, doxorubicin, vincristine) therapy and a partial response was achieved. In March 1989, he was again admitted complaining of right dull hypochondralgia accompanied by enlargement of primary tumor in the right lower lobe of the lung and metastases to mediastinal and intraabdominal lymph nodes. Because it was an aged and recurrent case, he was treated with continuous five-day infusion of etoposide, 30 mg/m2/day and CDDP, 18.5 mg/m2/day. After the second course, subjective symptoms clearly disappeared and swelling of mediastinal and intraabdominal lymph nodes was markedly reduced on computed tomography. No severe side effects except for moderate myelosuppression, alopecia and nausea were observed. This regimen appears useful in the treatment of small-cell lung carcinoma in elderly patients.

A 76-year-old man with spindle cell (squamous) carcinoma of the lung developed fatal respiratory failure after limited thoracic irradiation at a total dose of 18 Gy. He developed severe pulmonary toxicity, which presented as dry cough, dyspnea, and pulmonary infiltrates extending beyond the radiation field. Microscopically, a transitional form of squamous to spindle-shaped cells was observed in the primary tumor, located at right S8. Immunohistochemical examination showed positive staining of spindle cells for keratin, vimentin, and EMA, but not for desmin. These results indicate that the spindle cells had characteristics of squamous epithelial cells, and differed from carcinosarcoma. Distant metastatic lesions were composed of only the spindle cell component.

Pleural fibroma is a rare and benign primary tumor, mainly asymptomatic and of big size due to its slow growth from visceral pleura. Six patients (5 males and 1 female) with this pathologic condition were studied; the tumors had diameters ranging 2.5-18 cm. The diagnosis was occasional in 4 patients, while the extant presented with dyspnea, cough, and thoracic pain. Two large fibromas originating from the left basal visceral pleura failed to be correctly diagnosed on plain films, while 2 small pedunculated lesions exhibited blurred outlines at the pleural origin. On chest films, neither rib erosions nor pleural effusions or calcifications were detected. CT scans showed 2 small lesions to have both shape and localization typical of pleural origin, while a third pedunculated fibroma mimicked an intrapulmonary mass. Three huge fibromas, especially 2 of them originating from left basal pleura, were misdiagnosed by CT and topographic criteria. CT images after intravenous injection of contrast medium showed mainly a mottled and irregular densitometric pattern. A correct diagnosis was very difficult to make also with the help of CT-guided biopsy (performed on 5 patients), because the specimens had a fibrous content and were very small due the elasticity of the mass against the needle. All patients underwent surgery and were cured when discharged. Histology was always necessary for a conclusive diagnosis to be made.

The prognostic staging of cancer in general, and lung cancer in particular, has customarily depended mainly on morphologic distinctions. The gross anatomic extensiveness of cancers is cited with TNM stages that describe the primary tumor (T), spread to regional lymph nodes (N), and metastatic dissemination (M) to distant sites. Microscopic characteristics are cited according to the cancer's cell type (e.g., adenocarcinoma, epidermoid carcinoma) and/or grade of differentiation (e.g., well differentiated, poorly differentiated, anaplastic). Although the clinical manifestations, functional effects, and associated co-morbidity of a cancer are universally recognized as having major prognostic importance, they have not been classified with a standard system of taxonomy. When considered at all, clinical phenomena have been cited with a surrogate index of "performance status" that ignores the underlying clinical dysfunctions while being greatly affected by non-clinical phenomena, such as the patient's psychic status, economic motivations, and system of social support. The current research was done to develop a standard system of taxonomy (or "staging") for the prognostic impact of clinical distinctions in patients with primary lung cancer. Appropriate data were obtained, computer-coded, and analyzed from medical records for the complete clinical course of an inception cohort of 1266 patients who were first treated at either the Yale-New Haven Hospital or the West Haven Veterans Administration Hospital during the interval January 1, 1953-December 31, 1964. The information under analysis included clinical phenomena as well as anatomic extensiveness (TNM stage), microscopic histology, the chronometric duration of the interval from the first symptom of lung cancer to zero time, the iatrotropic reason why the patient sought medical attention, the presence of anemia, the amount of customary cigarette use, and the conventional demographic data for age and gender. The main clinical phenomena were expressed in variables for symptom pattern severity, and co-morbidity. Symptom pattern referred to the existence of specific pulmonic symptoms (e.g., hemoptysis), systemic symptoms (e.g., complaint of weight loss), and metastatic symptoms that might be mediastinal (e.g., superior vena cava syndrome), regional (e.g., the Horner syndrome), or distantly metastatic (e.g., central nervous system). The symptom severity variable included the amount of weight loss, and the existence of severe dyspnea or particularly severe tumor effects (such as mental obtundation, rather than hemiparesis in patients with CNS metastasis). Prognostic co-morbidity was cited for coexisting diseases, such as recurrent myocardial infarctions, that might be more lethal than the lung cancer itself.(ABSTRACT TRUNCATED AT 400 WORDS)

Thyroid tumors were diagnosed in 26 dogs between 1977 and 1984. A total of 23 of the 26 tumors were carcinomas, and 3, detected as incidental findings at necropsy, were adenomas. The median patient age was 9.5 years. Dogs of the Beagle breed were affected most commonly (5 dogs). The most common physical abnormalities in carcinoma patients were cervical swelling, dyspnea, and coughing. A total of 25 of 26 dogs were clinically euthyroid. Aspiration cytology provided diagnostic information in 8 of 17 cases. In dogs with thyroid carcinoma, a cervical soft tissue lesion was identified consistently by use of radiography and scintigraphy with sodium pertechnetate. Pulmonary metastases were detected radiographically in 8 of 21 dogs with thyroid carcinoma. Thoracic nuclear imaging confirmed the radiographic findings in 11 of 14 dogs. Surgical excision of the thyroid mass was the primary treatment for 17 dogs with carcinoma. Eight dogs died within 2 years (median, 7 months) of surgery because of primary tumor regrowth or metastases. Four dogs were alive at a range of 3 to 48 months after surgery, and 4 dogs died from unrelated causes. Necropsy of 7 dogs with thyroid carcinoma revealed neoplastic infiltration of the cervical blood vessels and pulmonary metastases in each dog. The most common histologic patterns of thyroid carcinoma were solid or compact cellular (11 dogs) and mixed solid-follicular tumors (8 dogs). Dogs with a solid carcinoma had a median survival time of 10.5 months (6 dogs), and dogs with a mixed solid-follicular tumor had a median survival time of 8 months (3 dogs).
