An analysis was made of 17 cases of microscopically proven rib neoplasms, with the objective of evaluating the variability of clinical and radiographic findings, the neoplastic cell types, the occurrence of metastases, and the survival time following the diagnosis. In 15 dogs with primary rib neoplasms and in 2 dogs with secondary (presumably metastatic) rib neoplasms, the clinical signs commonly included dyspnea and a localized swelling on the thoracic wall. For the dogs with primary rib neoplasms, the mean age was 4.5 years, with a range of 1.3 to 16 years. On radiography, rib osteolysis, extra and/or intrathoracic soft tissue masses often containing areas of mineralization, and pleural effusion were commonly identified. Ribs 5 through 9 were the most commonly affected and the right side was involved twice as often as the left side. Osteosarcoma was the most frequently diagnosed tumor, but chondrosarcomas and hemangiosarcoma were also found. At necropsy, over 50% of the dogs with primary rib neoplasms had metastases in the lungs. Less than 10% of the dogs with primary rib osteosarcomas survived more than 4 months after the diagnosis.

A program of reconditioning through walking was prescribed for 130 patients following an exercise test on a treadmill 3 weeks after a myocardial infarction. At 8 and at 12 weeks the patients again underwent an exercise test. The protocol is safe and permits the detection of angina, arrhythmias and dyspnea during the exercise, thus avoiding delays in treatment. The heart rate and the systolic blood pressure were measured at the end of each stage of the test and after 3 minutes of recuperation. About 75% of the patients attained the target energy output of the two submaximal tests (4 and 7 mets at 3 and 8 weeks respectively); an output of 7 mets permits a patient to resume his or her usual daily activities. The results of the tests at 3 and 12 weeks (the latter a maximal test) showed that the probability of an aerobic capacity of 7 mets or greater at 12 weeks is 86% if the 3-week test is completed. Clinical observations alone did not have the same prognostic value 3 weeks after the infarction.

Thirty-two patients seen in one area between 1974 and 1980 with a diagnosis of malignant pleural mesothelioma are reviewed retrospectively. Asbestos contact, often in the shipyards, was found in 80%. The average age at diagnosis was 64 years and chest pain or breathlessness were the most common initial symptoms. Radiology usually confirmed a pleural effusion, but rarely also showed pleural plaques or asbestosis. The most useful diagnostic investigation was pleural biopsy, with a 59% success rate. Post mortem examinations showed widespread infiltration of adjacent tissues in many, with haematogenous metastases in 52%. Prognosis was poor, with an average survival of 40 weeks from presentation. No treatment improved life expectancy. Thoracotomy was followed by painful chest wall masses. The incidence of mesothelioma in our area is six times higher than in the rest of Scotland. As the disease has a long latent period between asbestos exposure and appearance, it will be many years before this rate is significantly reduced.

After injury to the left foreleg, a 2 1/2-year-old Great Dane bitch developed severe oedema of the limb, which did not respond to pressure bandaging or a proteolytic agent. Skin breakdown occurred over the metacarpal region and lymph could be expressed from this lesion. The oedema spread, anaemia and dyspnoea developed and the animal died of respiratory insufficiency 55 days after the initial injury. Autopsy showed widespread infiltration of subcutis, fascial planes and some muscles of the leg by invasive cords and sheets of small endothelial-type cells which formed channels sometimes filled with blood. There was widespread diffuse metastatic neoplasm throughout the lung but no cavernous blood sinus formation. There were small metastases in local lymph nodes, kidney, bone marrow and spleen. It was concluded that the injury made obvious an oedema caused by pre-existing angiosarcoma.

A case of lung cancer manifested as cardiac tamponade was reported. A 64-year-old male had anterior chest pain and dyspnea. A chest X-ray films showed an enlarged heart with a solitary round shadow in the left lung hilus. Echocardiogram disclosed a large amount of pericardial effusion. Emergency pericardiectomy with drainage was accomplished. The patient lived for 8 months without effusion accumulation. Histologically adenocarcinoma of the lung with prominent lymph nodes metastases was disclosed. Surgical decompression such as pericardiectomy or pericardial fenestration is a valuable selection in the treatment of pericardial effusion and tamponade.

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.

This report describes a 26-year-old patient with hemangiosarcoma of the heart and summarizes the clinicopathological features in previous reports of patients with cardiac angiosarcoma. The patient was admitted to our hospital because of a syncope and one episode of nocturnal dyspnea and hemoptysis. In his history he complained of progressive weakness and loss of weight over the past 2 months. Echocardiography and computed tomography of the chest showed inhomogeneous masses in the pericardial cavity completely surrounding the heart and involving the ascending aorta and the superior vena cava. Histological examination of the tissue obtained from the mass by fine needle technique revealed a poorly differentiated malignant tumor of mesenchymal origin. Exploratory thoracotomy followed by tumor biopsies showed an inoperable cardiac hemangiosarcoma of enormous size with multiple metastases in both lungs. Palliative tumor resection was not performed. During the postoperative course the patient still required controlled ventilation. After 3 days of cytostatic chemotherapy no regression of tumor mass was seen by chest radiography. Cardiorespiratory insufficiency was progressive, and the patient died within 3 weeks after admission.

The lung is a common site for cancer to occur, for both primary as well as metastases. The presence of such tumours can give rise to symptoms such as haemoptysis, cough, breathlessness and pneumonia. In most cases, treatment is strictly for palliation. We present a case report of a patient with an endobronchial metastasis from a primary hypernephroma which recurred following external beam radiotherapy. He was treated with a single fraction of intraluminal brachytherapy to a dose of 10Gy at 1 cm from the axis on a High Dose Rate Ir192 Remote Afterloading Machine. There were no adverse effects following treatment. On follow-up 7 months later, the patient did not have any further recurrence of breathlessness although his disease had progressed at other sites.

Pulmonary blastoma (PB) is an uncommon primary lung malignancy. This neoplasm was first described by Barrett and Barnard in 1945. The tumor is composed of immature epithelial and mesenchymal tissues which may recapitulate early embryological lung development. Under the microscope, the globular component resembles immature bronchus and connective tissue as seen in embryonic lung. More than one hundred cases have been reported in the literature. PB is more frequent in older people and in males and tends to affect blacks at younger ages. Symptomatology varies from asymptomatic to symptoms of a non-specific pulmonary disease. Cough, hemoptysis, dyspnea, chest pain, respiratory distress, fever, anorexia and weight loss are the most common presenting features. The most common roentgenologic pattern is a well-demarcated peripheral lesion, encapsulated by compression or atelectatic lung tissue, although in some cases there is a tendency to lobulation and cavitation. The size of the mass varies from a small peripheral nodule to a mass occupying the entire lobe or hemithorax. The treatment of choice has been surgical excision, radiation and, in selected cases, a combination of chemotherapy with radiation. The prognosis of this malignancy is poor; overall five-year survival is approximately 16 percent. No correlation has been established between histopathologic criteria and survival. The factors that indicate poor prognosis are tumor recurrence, metastasis at initial presentation, tumor size over 5 cm and lymph node metastasis. Liver, central nervous system and bones are the most frequent location of distant metastases. A rare case is presented of a pulmonary blastoma with an upper lip metastasis occurring in a paraplegic male. Diagnosis was confirmed by autopsy findings.(ABSTRACT TRUNCATED AT 250 WORDS)

Four cases are described of a distinctive morphologic variant of thymic carcinoid that was characterized by abundant stromal mucin admixed with the neuroendocrine elements resulting in a histologic picture reminiscent of metastatic mucin-secreting carcinoma. The patients were three men and a woman, aged 22 to 43 years. The tumors presented with symptoms of chest discomfort, cough, and dyspnea and were described as large anterior mediastinal masses on chest radiographs and computerized scans. Histologically, all cases showed nests and strands of tumor cells embedded in an abundant lightly eosinophilic, mucinous stroma with small cellular clusters as well as scattered single tumor cells seen floating in the mucin. The mucinous matrix was negative for periodic acid Schiff's and mucicarmine stains; alcian blue stains at pH 2.5 showed strong positivity of the mucinous material; this reaction was abolished by treatment with hyaluronidase, indicating the presence of nonepithelial stromal mucosubstances. Immunohistochemical stains showed strong positivity of the tumor cells with CAM 5.2, chromogranin, synaptophysin, and neuron-specific enolase, and negative staining with carcinoembyronic antigen and epithelial membrane antigen. Electron microscopy done in one case showed abundant dense-core cytoplasmic neurosecretory granules; there was no evidence of glandular secretory activity by the tumor cells. The tumors in two patients behaved in a highly aggressive fashion, with invasion of the chest wall, recurrence, and metastases to the lungs, pleura, and axillary, retroperitoneal, and mesenteric lymph nodes. Thymic carcinoid should be considered in the differential diagnosis of mediastinal neoplasms displaying prominent mucinous features. Application of immunostains and electron microscopy will be of value for establishing the correct diagnosis in this setting.
