A 43-year-old male was admitted to our hospital with chief complaints of stridor and dyspnea. Bronchoscopy revealed a tumor obstructing almost the whole lumen of the trachea. As it was impossible to insert an endotracheal tube into the distal site of the stenosis in the mediastinum, we used partial cardiopulmonary bypass to maintain gas exchange. The axillary artery and the femoral artery and vein were cannulated for the bypass using local anesthesia. During 105 minutes of bypass, the PaO2 value was good but the PaCO2 value increased up to 70 mmHg. After the trachea was opened, the anesthetic gas was administered across the operative field through the endotracheal tube and the cardiopulmonary bypass was discontinued. Tracheolaryngectomy and permanent tracheostomy with relocation to the right and caudal side of the brachiocephalic artery was performed successfully. The post operative course was very smooth. The patient has been well for 6 months since the surgery. Partial cardiopulmonary bypass proved to be useful for maintaining gas exchange during reconstructive surgery of the trachea. We treated a case of tracheal carcinoma by resection while using partial cardiopulmonary bypass. We believe this is the ninth such case reported Japanese literature.

A 78-year-old man was admitted to the Nishinomiya Municipal Central Hospital with main symptoms of chest pain and dyspnea. Chest CT revealed a large mediastinal mass shadow, and echocardiography revealed pericardial effusion. Serum LDH was elevated. Therefore, malignant lymphoma was suspected to be the cause of cardiac tamponade. VEPA chemotherapy was commenced. Half way through the course of chemotherapy, serum LDH was decreased, the pericardial effusion had disappeared, and the mediastinal mass was reduced in size. A biopsy specimen of the mediastinal tumor revealed malignant lymphoma of diffuse large cell type, and immunoperoxidase staining of frozen sections demonstrated B cell origin. The pericardial effusion had not increased in size after four months, when the patient developed pneumonia and died. Autopsy revealed pericardial and atrial involvement by tumor. In conclusion, this case is very unusual in that (1) pericardial involvement was suspected on admission; (2) the pericardial effusion disappeared with systemic chemotherapy; and (3) cardiac metastasis was demonstrated at autopsy.

The patient was a 64-year-old male with undifferentiated carcinoma of the thyroid which constricted the trachea. The radiation therapy did not reduce the size of the tumor, and did not improve the dyspnea. Bronchoscopy and tomography showed a compression stenosis of the cervical and mediastinal trachea. It was difficult to insert the T-tube because of the large mass of the neck. Therefore, three EMSs were inserted into the stenotic area of the trachea. Immediately after the insertion of the EMSs, the lumen of the trachea was dilated, and the dyspnea was improved. The patient died of the tumor 7 weeks after the insertion of the EMSs. Autopsy showed that the trachea was dilated by EMSs.

In May, 1989, a-54-year old man was admitted complaining of sore throat and tumor of the neck which had persisted for 2 months. Mid-pharyngeal tumor was diagnosed as poorly differentiated squamous cell carcinoma (stage, T3N2M0) and the patient was treated with radiation (Co 65Gy) from May 30 to July 24 and chemotherapy (UFT), which therapies were effective. On Aug. 16, sudden onset of consciousness disturbance and hemiparesis was revealed, and MRI showed small cerebral infarction. He died on Oct. 23, of pneumonia. Pathological diagnosis revealed a case of carcinoma of the mid-pharynx with wide-spread tumor embolism. Multiple cerebral and myocardial infarctions, thrombus in pulmonary arteries and congestion of kidneys with tumor emboli, due to "disseminated intravascular carcinomatosis" were noticed. A direct cause of death was dyspnea due to multiple lung metastases, pneumonia and tumor embolism in the pulmonary and coronary arteries.

We have presented a rare case of pulmonary tumor microemboli from adenocarcinoma of the colon. The majority of primary tumors are adenocarcinomas, with gastric, breast, and liver carcinomas most frequently identified. Dyspnea and respiratory distress without an obvious cause is common. The history, physical examination, chest roentgenogram, ventilation-perfusion lung scan, and pulmonary angiogram are often not helpful in establishing the diagnosis. Pulmonary hypertension, present in our patient, and cor pulmonale are well described in association with diffuse pulmonary tumor microemboli. The pathologic findings are limited to the intravascular compartment exclusively, frequently in association with thrombus. The true incidence of pulmonary tumor microemboli is not known and may be underestimated. Appropriate management requires a high index of suspicion to establish the diagnosis.

We report a case of renal cell carcinoma with pulmonary metastases treated with recombinant alpha interferon and subsequently presenting as congestive heart failure due to a dilated cardiomyopathy. A 66-year-old man presented himself to the department of internal medicine at our hospital with a complaint of persistent cough with sputum on August 27, 1988. Ultrasonogram, computed tomography and angiography showed a right renal cell carcinoma and chest x-ray films disclosed bilateral multiple nodular shadows, probably representing metastases of the renal tumor. After being transferred to our department, the patient underwent the ligation of the right renal artery and vein and the postoperative treatment with recombinant alpha interferon, achieving a complete response for pulmonary metastases and a partial response for the primary region. On February 14, 1990 the patient was admitted to our hospital with a complaint of dyspnea to be diagnosed as congestive heart failure due to dilated cardiomyopathy. The interferon therapy was suspected to have caused the heart disease, and four months after discontinuation of interferon therapy the heart failure symptoms had improved, but hypokinesis of the cardiac wall still persisted. To our knowledge, this may be the first case of alpha interferon-related cardiomyopathy in Japan.

The involvement of the pulmonary vessels by tumour emboli may lead to a clinical picture defined as 'subacute cor pulmonale'. Information about this syndrome has been limited to case reports and a few series. A study of 214 autopsied cancer patients was undertaken to investigate the clinical signs and symptoms of tumour involvement of the pulmonary vessels (TIPV). The lungs were removed as a block and 15 sections (3 from each lobe) were analyzed. Clinical data about right ventricular failure, dyspnoea, cough, pleuritic chest pain, cyanosis, engorgement of jugular veins, peripheral oedema, haemoptysis and haemoptoic sputum were obtained from the medical records of each patient. Tumour emboli were detected in 89 cases, and no respiratory symptoms were recorded in 39. The presence of dyspnoea and cyanosis were highly significant in the group with TIVP, and right ventricular failure and peripheral oedema showed slight significant differences between the patients with and without TIPV. The classical picture of subacute cor pulmonale was observed in 13 patients and TIPV was considered to be the main cause of death in 29 cases. Our results indicate that although the development of subacute cor pulmonale was rare in patients with cancer, TIPV may be suspected when the patient presents respiratory distress and should be included in the differential diagnosis of dyspnoea in cancer patients.

A 23-year-old female was admitted with dyspnea, dry cough, and rhonchi. No abnormalities were detected on chest roentgenogram. Fiber-bronchoscopy revealed a polypoid lesion with necrotic material occluding the left main bronchus. The pathological diagnosis of the biopsied material was low grade mucoepidermoid carcinoma. Following tumor reduction by Nd-YAG laser, it was clear that the primary lesion originated from the left upper bronchus. Sleeve lobectomy was performed, and the tumor was proved to be early lung cancer of hilar type with extension limited to the bronchial wall.

A 66-year-old postmenopausal woman presented in June 1991 with a giant ulcerated left breast tumor. She had discovered the tumor two years previously, but had never visited any medical institution. She was diagnosed as advanced breast cancer with multiple lung metastases, bone metastasis, and both supraclavicular lymph node metastases by physical examination, fine needle aspiration cytology, chest X-P, and bone scintigraphy. Incisional biopsy, performed to confirm the histological type of breast cancer and to evaluate estrogen and progesterone receptor (ER and PgR) status, revealed solid-tubular carcinoma. Both ER and PgR were highly positive at 322.6 and 228.0 fmol/mg protein, respectively. Therefore, endocrine therapy was chosen to treat this advanced breast cancer patient, although she had multiple organ metastases. Twenty mg of Tamoxifen a day was administered per os. After treatment with tamoxifen, the size of ulceration started to decreased and the dyspnea caused by multiple lung metastases was reduced. Eight weeks after, she showed partial response (PR) determined from the size of the ulceration and chest X-P. She has been maintaining PR for more than 9 months. Thus, Tamoxifen was shown to be very effective for this case of advanced breast cancer with multiple organ metastases.

A 15-year-old girl who presented with cough and dyspnea was found to have a mediastinal tumor that clinically resembled a lymphangioma. The tumor was unusual for its large size and its histologic features, which showed smooth muscle proliferation, generally considered a feature of lymphangiomyoma.
