A chondrosarcoma arising in the posterior cricoid plate is presented. The tumour gave rise to increasing inspiratory stridor: laryngectomy was performed. The tumour consisted of loose cartilaginous tissue with great predominance of highly differentiated cartilage cells and only small areas with nuclear polymorphism. This complicated the differential diagnosis between chondroma and highly differentiated chondrosarcoma. From the fact that the patient died from massive pulmonary metastases 3 1/2 years later, it is evident that the degree of malignancy of cartilaginous tumours should be determined even on small polymorphic foci. The DNA histogram for the foci of the laryngeal tumour with atypia differed distinctly from those for benign chondroma and normal cartilage, but resembled those of the pulmonary and splenic metastases and of a nasal chondrosarcoma. Photometric examination may provide an aid in the difficult differential diagnosis between chondroma and highly differentiated chondrosarcoma.

This retrospective study comprises 45 patients with subglottic carcinoma, arising either primarily or by spread from glottic carcinoma. The relevant literature is reviewed. Points of interest concerning the natural history of these carcinomata are: 1) The incidence of primary subglottic carcinoma was seven per cent of all laryngeal carcinomata and the incidence of subglottic spread of glottic carcinoma was 11.4 per cent. 2) At the time of presentation, vocal cord fixation was present in 40 per cent of the total group; 16 per cent of the true subglottic group had palpable nodes in the neck, and 5.5 per cent of the subglottic spread group. 3) Of the patients with true subglottic lesions, 44 per cent were women, 64 per cent presented with stridor and 32 per cent required emergency tracheostomy, 32 per cent developed distant metastases, half of these being in bone. 4) Only one of 45 patients developed mediastinal metastasis.

Most of the symptoms from a malignant tumor are caused by local invasion by the tumor, or obstruction, either at the site of the primary disease or by metastases. However, tumors can produce symptoms at a remote site. Patients with gastrointestinal malignancy may present with symptoms which include dysphagia, nausea, vomiting, abdominal pain, diarrhea, bleeding and ascites. Palliation gastrectomy delays or prevents these symptoms. About 30% of gastric carcinomas are inoperable at the time of presentation. Chemotherapy is rarely effective in the palliation of gastric carcinoma. Laser irradiation can be delivered to assay site accessible to fibreoptic endoscopy, which is an advantage over endocavity irradiation or diathermy fulguration. Ascites is a common and disabling implication in patients with advanced malignant disease. Spironolactone will increase urinary sodium excretion significantly and control their ascites. If spironolactone fails to control, useful control can be achieved by draining the ascites. Patients with carcinoma of the lung may present with symptoms that include cough, bloody sputum and dyspnoea. Pain in the chest wall is usually secondary to invasion of the parietal pleura, ribs or intercostal nerves. Lesions in the medial portion of the right upper lobe, or mediastinal metastases, may invade or compress the superior vena cava, causing venous hypertension with oedema of the head and arms. The patients may complain of dyspnoea, dysphagia, stridor and headaches. Radiotherapy can be expected to improve the quality of life for these patients. Successful palliation of symptoms is almost related to tumor regression. The problems of obstruction and bleeding from malignant tumor is common. Recently, laser techniques have been applied to aid in palliation of these problems. Malignant effusion may occur early and be the first signs of metastases. The aim of therapy is to evacuate the fluid and induce pleural adhesion. One of the sad situations that we have to face is the patient with recurrent cancer which complains of various symptoms. The relief of symptoms is the most important palliative therapy to them.

Photodynamic therapy is a recently introduced treatment for surface malignancies. Since January 1987, 10 patients with endobronchial neoplasms have had bronchoscopic photodynamic therapy at similar dose rates (400 mW/cm) for total atelectasis (2), carinal narrowing with respiratory insufficiency (2), or partial obstruction without collapse (4). Two patients underwent photodynamic therapy as a preliminary to immunotherapy. Histologies included endobronchial metastases (colon, ovary, melanoma, and sarcoma, 1 each; and renal cell, 3) and primary lung cancer (3). The 2 patients with total atelectasis had complete reexpansion after photodynamic therapy, which permitted eventual sleeve lobectomy in 1. Carinal narrowing was ameliorated in the 2 patients seen with inspiratory stridor, thereby permitting hospital discharge. Endoscopically resected fragments after photodynamic therapy exhibited avascular necrosis. These data support further controlled studies of photodynamic therapy by thoracic surgical oncologists to define its limitations as well as to improve and expand its efficacy as a palliative or surgical adjuvant.

Patients with multinodular goiter or related thyroid disorders rarely have acute airway distress due to tracheal deviation or compression. However, our institution cares for a large number of patients with untreated multinodular goiters, and in the progression of this disorder, tracheal deviation and airway problems are relatively common. During the past 4 years, we have cared for 24 patients who were admitted with acute, life-threatening airway distress that required emergency intervention. Nine patients had emergency intubation, the remaining 15 had stridor on admission and underwent emergency operations. The series consists of 19 females and five males whose ages ranged from 37 to 89 years. Only four patients had malignant thyroid lesions (two papillary-follicular, two anaplastic), and two of these had multiple pulmonary metastases. Fifteen of the patients with multinodular goiters had a mediastinal extension that led to marked tracheal deviation. Three patients had recurrent multinodular goiters decades after previous surgery. Twenty-one patients underwent surgery at our institution, and all did well. Only one patient required sternotomy for thyroidectomy. Two patients required tracheostomy procedures, one because of tracheomalacia and the other because of poor pulmonary reserve. Interestingly, two patients had acute symptoms when in their third trimester of pregnancy. We have routinely used the laryngoscope (fiberoptic rigid or flexible) for preoperative and postoperative evaluation of the vocal cords and for determination of the condition of the larynx. On the basis of our experience with acute airway distress, we strongly advocate elective surgery for patients with multinodular goiter at the first sign of tracheal compression, especially if they have mediastinal extension.

We present the fourth reported case of metastases of adenocarcinoma from the prostate to the larynx. The patient was a 64-year-old male who presented with stridor from a smooth subglottic mass six months after he had been diagnosed as having adenocarcinoma of the prostate with bone secondaries. We have reviewed the mechanisms by which such a tumour might metastasize to the larynx and we feel that ossification in the laryngeal cartilages may be important in the development of such metastases.

A case of metastatic tumor in the larynx following successful treatment of a breast carcinoma and a colon carcinoma is presented. The lesion was visible by indirect laryngoscopy, and computed tomography of the larynx assisted in delineating the extent of the disease. The separation of primary adenocarcinoma of the larynx from metastases is discussed, as is the identification of the origin of a metastasis where two separate primaries have existed. Other reports of cancer metastatsizing to the larynx are reviewed. Tumor spread to the larynx may be asymptomatic or may result in hoarseness, stridor and/or airway obstruction.

At the age of three months an infant rapidly developed signs of cardiac failure as well as in- and exspiratory stridor, caused by an intrathoracic tumor. Thoracotomy and biopsy revealed an intrapericardial tumor, histologically myxosarcoma. In spite of chemotherapy and radiation the infant died at the age of seven months due to multiple intracerebral metastases now histologically rhabdomyosarcoma. This is one of the rare cases of primarily malignant intrapericardial tumors in infancy, and also shows the possible pleomorphism of childhood rhabdomyosarcoma. We know only one further case of pericardial rhabdomyosarcoma where similar histologic changes have been observed.

The management of patients with critical major airways obstruction has been made possible by the recent introduction of expandable metal stents as the sole treatment or as an adjunct to other treatment modalities, to alleviate the distressing symptoms from tracheobronchial obstructions Gianturco self-expanding stents were used successfully in the management of 27 patients. The indications were: stenosis from postoperative strictures and recurrent tumours (n = 6), extrinsic compression from metastatic disease (n = 9), inoperable primary tumours of central airways (n = 9), airway collapse from relapsing polychondritis (n = 1), excessive mediastinal shift following right pneumonectomy (n = 1) and endobronchial non-Hodgkin's lymphoma (n = 1). Twenty three patients had immediate relief of stridor and the remaining two patients were successfully weaned from ventilatory support. There were two postoperative deaths. The stents were inserted under general anaesthesia through a rigid bronchoscope under direct vision. The ease of insertion under radiological control, self-expanding nature of the stents and the lack of major complications on follow-up of up to 47 months are particular advantages. The self-expanding tracheobronchial stents are a useful addition to our armamentarium in maintenance of the airways in patients with major airway stenosis and collapse.

The management of patients with critical major airway obstruction has been made possible by the recent introduction of expandable metal stents as the sole treatment or as an adjunct to other treatment modalities. To alleviate the distressing symptoms from tracheobronchial obstructions Gianturco self-expanding stents were used successfully in the management of 16 patients. The indications were; stenosis from postoperative strictures and recurrent tumours (n = 6), extrinsic compression from metastatic disease (n = 4), inoperable primary tumours of central airways (n = 4), airway collapse from relapsing polychondritis (n = 1), and endobronchial non-Hodgkin's lymphoma (n = 1). Fourteen patients have immediate relief of stridor and the remaining two patients were successfully weaned from ventilatory support. The stents were inserted under general anaesthesia through a rigid bronchoscope under direct vision. The ease of insertion under radiological control, self-expanding nature of the stents and the lack of major complications on follow-up of up to 22 months are particular advantages. The self-expanding tracheobronchial stents are a useful addition to our armamentarium in maintenance of the airways in patients with major airway stenosis and collapse.
