Tumor embolization was found at autopsy in the pulmonary arteries of 33 of 331 patients dying with primary carcinoma of the lung (other than oat cell carcinoma). Venous or lymphatic vascular involvement, or both, was greater frequency of tumor embolization htan epidermoid carcinomas (16.5% vs. 5.8%). In 16 of the 33 cases, diffuse, obliterative intimal fibrosis was found in small arteries affected by the tumor embolization. Enlargement of the right cardiac ventricle was present in 26 of the 33 cases. Dyspnea as the initial symptom or as one of the major symptoms, occurred in 21 patients. The average interval between onset of dyspnea and death was 4 weeks. It is concluded that pulmonary arterial embolization is a relatively frequent complication of primary lung carcinoma, particularly adenocarcinoma, which may lead to the developemnt of pulmonary hypertension and cor pulmonale Dyspnea, occurring de novo in patients with primary lung carcinoma is an ominous sign and should alert the clinician to the possibility of arterial pulmonary tumor embolization.

A retrospective study was undertaken in 1990 of 188 patients with the diagnosis of non small cell carcinoma of the lung referred to the Department of Radiation Oncology in 1984. Most patients (178/188) received a course of radiotherapy. This was definitive in 23, palliative in 148 (primary site in 113, metastases in 16, primary plus metastases in 19) and postoperative in 7. This report is a 5 year followup of the 171 patients treated by radiation alone, to assess factors that influence survival. Tumour histology was 50% squamous, 23% adenocarcinoma, 16% large cell and 4% unspecified, non small cell carcinoma. In 8% no histological diagnosis was obtained. The most common symptoms were cough (44%), dyspnoea (43%), chest pain (37%), haemoptysis (33%) and systemic symptoms (36%). Tumour stage (TNM) was assessed retrospectively as I(5%), II(8%), IIIA(18%), IIIB(22%) and IV(28%). A subgroup of 31 cases (18%) of uncertain staging (I-III) was analysed separately and in 2 cases (1%) no staging information was available. Palliative intent of treatment and poorer performance status were related significantly to increasing stage of disease. The effects of palliative treatment were recorded in 79 cases; in 71 there was a reduction in symptoms. The median survival from diagnosis was 8 months (range < 1-72). Using univariate and multivariate analyses, significant and independent prognostic factors for improved survival were good performance status, absence of systemic symptoms, lower tumour stage and curative intent of treatment (higher radiation dose). However the 5-year survival was only 2%. Long-term survival was associated predominantly with early stage disease but not with the type or intent of treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

An autopsy case of pulmonary metastasis of cholangiocellular carcinoma is presented. A 44-year-old woman was admitted to our hospital because of dyspnea, general fatigue and a sense of abdominal fullness on February 5, 1990. In November 1986, at an other hospital, she had been diagnosed as having diffuse metastatic lung tumor and multiple bone metastases, by transbronchial lung biopsy and other examinations. During the clinical course, she was not received chest irradiation and chemotherapy which induced fibrotic change of lungs. Chest X-ray film on December 21, 1986 showed diffuse nodular shadows in both lung fields. Chest X-ray film on February 4, 1990 showed diffuse reticular shadows with marked shrinkage of lung fields. She died two months after admission. The primary site of the carcinoma was not determined clinically, but was revealed by autopsy to be cholangiocellular carcinoma of the liver, with generalized metastasis. Microscopic findings of the autopsied lung showed markedly increased connective tissue around bronchi and blood vessels, in areas where microtubular adenocarcinoma was scattered. This is a very rare case of pulmonary metastasis of cholangiocellular carcinoma, associated with marked fibrotic change of the lungs during about 3.5 years. To our knowledge, this is the first reported case.

The staphylococcal cell-wall protein known as protein A has been explored as a therapeutic modality in the treatment of cancer and allied diseases. Protein A binds the Fc fragment of IgG 1, 2 and 4, and preferentially binds to IgG incorporated into immune complexes. Early investigators focused on the immune-suppressive effects of immune complexes in cancer and, based on in vitro experiments, postulated that clearance of immune complexes in vivo would permit effective immune clearance of cancer cells. A large clinical trial of the perfusion of cancer patient plasma over protein A was subsequently undertaken. Results were generally disappointing, with no complete remissions and overall response rates of 22%. Response rates for Kaposi's sarcoma (39%) and breast adenocarcinoma (26%) were somewhat encouraging, and further clinical trials in these disorders are ongoing. More impressive have been the responses to protein A perfusion in immune thrombocytopenia and hemolytic-uremic syndrome. Using a protein A-silica device, Snyder et al. reported responses in 42% of immune thrombocytopenia patients, with mean increases in platelet count from 27 x 10(9)/l to 120 x 10(9)/l. On the basis of these results, the protein A-silica column was approved by the United States Food and Drug Administration for treatment of immune thrombocytopenia. Equally encouraging are reports of an overall 59% response rate in cancer chemotherapy-related hemolytic-uremic syndrome. Reported toxicities include fever, chills, hypotension, dyspnea and musculoskeletal pain. With rare exceptions, these reactions are easily treated and do not result in cessation of therapy. Unfortunately, the mechanism of action of plasma perfusion over protein A is very unclear.(ABSTRACT TRUNCATED AT 250 WORDS)

The incidence of lung cancer in 45 patients (37 males and 8 females), who were originally diagnosed as having idiopathic interstitial pneumonia (IIP), was studied prospectively by following them 4 to 10 years. As controls, sex-, age-, and smoking history matched patients with chronic obstructive lung disease (COLD) were also surveyed for the same follow up period. In addition, the differences in clinical findings between those with and without lung cancer were examined. Eight out of 45 patients with IIP (18%) developed lung cancer (adenocarcinoma; 4, small cell carcinoma; 3, squamous cell carcinoma; 2, including one double cancer). All lung cancer patients were male smokers. Looking only at males, 8 out of 37 patients with IIP (21.6%) developed lung cancer. This incidence was significantly higher than that of the male COLD group (2.2%, less than 0.01). In clinical findings, IIP patients with lung cancer had the characteristics of the chronic type of IIP (lack of volume loss on chest radiographic milder dyspnea, not on steroid treatment) when compared with those who did not develop lung cancer.

A hybrid gene comprising the bovine thyroglobulin gene promoter and the coding region for the simian virus-40 large T- and small t-antigens was used to generate 30 transgenic mice by microinjection into the pronuclei of single cell embryos. All animals except three developed, as single primitive pathology, a dramatic enlargement of the thyroid gland. Compression of trachea and esophagus, accompanied by dyspnea, inspiratory stridor, and dysphagia, led to a progressive cachexia and premature death attributed to respiratory failure. Despite the large thyroid volume, T4 levels were abnormally low, and the progression of the syndrome could be delayed by a substitutive treatment with thyroid hormones. The rapid evolution of the disease, leading to the death of most founder transgenic animals before the breeding age, prevented transmission of the transgene to their offspring. Only two transgenic lines are presently surviving. Immunohistochemical analysis of the tissues revealed a specific expression of the simian virus-40 antigens in the thyroid cells. Hyperplasia was already obvious at birth. Older animals displayed moderately to poorly differentiated thyroid adenocarcinomas. Electron microscopy revealed, however, the persistence of cell polarity and the presence of microfollicles between the densely packed cells. Cell lines derived from these large T-expressing thyroids were shown to have lost expression of both thyroglobulin and thyroperoxidase, while expressing low levels of TSH receptors. These transgenic mice could constitute an interesting model of aggressive adenocarcinoma, sharing phenotypical similarities with the anaplastic type of human thyroid tumors.

Thirty-seven patients with tracheobronchial lesions by malignant tumor were treated with Nd-YAG laser. Thirty-seven patients were twenty-three males and fourteen females and ages ranged from 34 to 79 years. Diseases included were primary tracheal tumor in 3 cases, lung cancer in 16 (8 squamous cell carcinoma, 5 adenocarcinoma, 2 large cell carcinoma, 1 small cell carcinoma), cancer of adjacent organs in 9 (5 thyroid cancers, 4 esophageal cancers), and metastatic cancer to the lung or mediastinal lymph nodes in 9 (4 renal cell carcinoma, 2 thyroid cancer, one patient respectively, colon cancer and breast cancer). Intermittent irradiation of YAG laser was done for 0.5 second at 30-40 Watt through flexible bronchoscope under local anesthesia. It was repeated 1 to 41 times (mean 4.1 times) and energy amount was 148 Joules to 18,513 Joules (mean 3,305 J). The result was; stenosis disappeared in 22 cases (59.4%), improved in 14 (37.8%), and in one case YAG laser therapy discontinued due to intractable bleeding. The Nd-YAG laser therapy for tracheobronchial lesions by malignant tumor is very useful to improve dyspnea or atelectasis.

A 63-year-old female, who had been suffering from idiopathic interstitial pneumonia (IIP) since two years and four months previously, was admitted with general fatigue, body weight loss, bloody sputum and progression of dyspnea. Chest roentgenogram on admission showed diffuse coarse ring shadows in the right middle and lower lung fields and in the left middle lung filed. Chest CT clearly showed honeycombing in bilateral dorso-basal segments of the lung. Serum CA19-9 level was elevated, and continued to increase during her clinical course. Sputum cytology was positive. Autopsy showed papillary adenocarcinoma of the lung (alveolar cell type). Immunohistochemical study of lung tissue showed positive CA19-9 staining on the surface of adenocarcinoma cells.

Pleural mesotheliomas are uncommon tumors that can be classified as localized or diffuse. Diffuse pleural mesotheliomas are invariably malignant. Although the frequency is low in the general population, it is more common in persons with a heavy occupational exposure to asbestos, and is considered as a signal tumor to asbestos exposure with medicolegal consequences. Mesothelioma incidence has been steadily rising during the past two decades, reflecting the increase in asbestos exposure during and following World War II. Clinical features include initial complaints of nonpleuritic chest pain and dyspnea. Distinguishing malignant mesothelioma from metastatic adenocarcinoma can be difficult, and can require large tissue biopsy with special stains and electron microscopy. The median survival of about 9 to 12 months confirms the poor outcome of pleural mesothelioma. The clinical deterioration is primarily attributable to locoregional spread of tumors, but metastasis is not rare. Several factors seem to have a prognostic value: performance status, stage, platelet count, age, histologic subtype, and asbestos exposure. In spite of the different therapeutic modalities such as surgery, radiotherapy, and chemotherapy used alone or in combination, the median survival is fairly different from survival among untreated patients. Because of the uncommon occurrence of this tumor and the existence of several different prognostic categories, a cooperative effort will be necessary for future therapeutic trials. If these active new therapies are identified, it would be useful to compare them to a best supportive care regimen in order to demonstrate an advantage of the treatment.

We report a primary malignant mixed mesodermal tumor in the right ovary of 75-year-old woman. She was admitted to Kobe West Municipal Hospital because of an abdominal fullness and an upper abdominal pain. A laparotomy yielded yellowish-clear ascites (2,000 ml) a tumor located in the right ovary, an upper abdominal mass the size of a child's head between the stomach and the transverse colon, and disseminating small tumors of the peritoneum. The left ovary and uterus showed no particular change. Four months after the onset of her symptoms, the patient died of carcinomatous cachexia and dyspnea. On microscope examination, the tumor of right ovary showed combined features of an adenocarcinoma, an adenosquamous carcinoma and a serous cystadenocarcinoma with foci of a heterologous stromal differentiation, that is an area of immature, striated muscle cells, bone, and cartilage and undifferentiated spindle cells. Immunohistochemical stains were useful for determining elements of the tumor cells. Epithelial tumor cells were positive for cytokeratin, epithelial membrane antigen, and CEA, while mesenchymal tumor cells were generally positive for vimentin and the immature muscle cells were especially positive for desmin, actin, and myosin. Additionally, myoglobin was identified in the rhabdomyoblast. Finally, S-100 protein was present in cartilage area and partially present in the adenocarcinomatous element.
