An extremely rare case is reported of a primary oat-cell carcinoma of the larynx in a 70-year-old man who had been treated eight years previously for squamous-cell carcinoma of the larynx by means of supraglottic laryngectomy. A review of the literature revealed only 5 unequivocal previous reports of this primary oat-cell tumor; the present report makes a total of 6 cases. The morphologic pattern, histogenesis and biologic behavior are discussed. The patient of this report was treated by surgical intervention and radiotherapy. He was well, six months later. Only one of the 5 patients previously reported survived for more than a few months. This type of lesion has a poor prognosis because of its tendency to metastasize early to various organs.

The case of primary oat-cell carcinom of the larynx with metastases in the thyreoid gland and paratracheal lymphnodes is reported on. The different methods of treatment are examined, used examples of the much more common oat-cell carcinoma of the lung. The applicability of the methods to oat-cell carcinoma of the larynx is discussed. Our treatment scheme of surgery and extended radiation is used if the tumor is known to be locally restricted.

Twenty-two patients with advanced laryngeal cancer and 5 with advanced pyriform sinus cancer were given 51 Gy (5,100 rad) followed by surgical resection. In 10 (45%) of patients with laryngeal cancer, no tumor was found at the primary site pathologically; 15 (68%) had negative neck specimens. All of those with pyriform sinus cancer had positive specimens. Eighteen patients with laryngeal cancer are free of disease. In contrast, only 1 with pyriform sinus cancer is free of disease; 1 has had a local recurrence and 3 have had metastases. The data suggest that 51 Gy (5,100 rad) are insufficient to sterilize pyriform sinus cancer; higher doses together with adjuvant chemotherapy are needed.

Difficult indications for certain partial laryngectomies are presented. Anatomically, the difficulties stem from the thyroid cartilage and from the paraglottic space in which invasion (difficult to determine) is contradictory for partial surgery. The principal objective is the cure of the laryngeal cancer all in maintaining laryngeal function. The surgeon must conserve a 'minimal' arytenoid unit' (the whole formed by the pharyngoepiglottic fold, the aryepiglottic fold, the arytenoid and the corresponding cord). Other difficulties not carcinogenic are found: physical conditions, social and professional situation, and preexisting local problems (associated laryngocel or previous vocal palsy). Finally, carcinogenic difficulties can be seen: the situation of the tumor, the rapidity of its evolution, anatomopathologic type, presence of nodes and metastases and previous physiotherapy and chemotherapy.

Various modifications of the standard radical neck dissection operation have been advocated since its original description. An ideal operation would offer maximum cure rates with minimal cosmetic and functional disturbance. The validity of removing the submandibular triangle contents as part of radical neck dissection was studied by analyzing the involvement of this region by metastatic squamous cell carcinomas of the head and neck. Only three of the 51 neck-dissection specimens that were examined contained metastases to submandibular triangle lymph nodes. The primary sites were nose, floor of mouth, and retromolar trigone. None of the 26 laryngeal tumors in this series had spread to the submandibular triangle. In the absence of palpable submandibular or upper, deep cervical lymph nodes, the contents of the submandibular triangle can probably be left undisturbed in radical neck dissections for laryngeal cancer.

Report on 5 cases of adenoidcystic carcinoma of the larynx and review of the literature, containing about 60 further reports. About 80% of these tumors arise in the subglottice laryngo-tracheal transition region, 20% in the ventricular cord and the epiglottis. The vocal cords containing no mucus glands are never the origin of adenoid cystic carcinomas. These tumors grow under an intact mucosa and reach very often an enormous extension until dyspnoea, dysphagia and recurrent never paresis lead to diagnosis. The clinical course of these tumors ist not preditable--even not by their histological structure. In some cases the outcome is rapidely fatal by local growth and metastases, in others a many year long survival can be reached, but there exists no reliable report on a "cured" adenoid cystic carcinoma of the larynx. By radical surgery only better results can be expected. Irradiation produces long lasting remissions in some cases.

The study of 112 case histories of lung cancers, both primary and secondary, has allowed the authors to determine as being of 5% the incidence of primary bronchogenic carcinoma associated with treated pharyngo-laryngeal cancer. One out of three such primaries was a solitary lung opacity. Bronchogenic primaries appeared be almost as frequent as lung, pleura and mediastine secondarie. They can be diagnosed at any moment of the treatment or follow-up of pharyngo-laryngeal cancer, and appear to occur later than pulmonary metastases. Their symptoms are more "bronchopulmonary" in nature. They are more frequently associated with endolarynx and chorda carcinomas. They are possibly more frequent in cases of smaller primaries without lymph-node involvement. Solitary lung opacities should be considered as independent primaries and constitute the best candidates for efficient pulmonary treatment. Treated pharyngo-laryngeal patients should undergo regularly spaced lung roentgenograms and frequent tracheal sputum cytology.

A total of 348 out of 349 patients with laryngeal cancer were treated over the period 1960-1970. Radiation therapy alone was used in 262 of them and surgical intervention with postoperative irradiation in 86. Results in the form of a five-year survival rate in the group treated solely by irradiation were superior by 12% in the case of glottic than in that of supraglottic carcinoma (48.8% and 36.8% respectively). In the group of patients operated upon and subsequently irradiated, relatively satisfactory results were obtained in the advanced, i. e. the III stage of supraglottic carcinoma (5-year survival in 61.4%). The overall 5-year survival rate in the patients operated upon and then irradiated proved to be better by 24.5% in supraglottic and by 4.1% in the glottic carcinoma, than in patients subjected solely to irradiation. Of 27 cases of relapses, 6 patients were successfully treated by laryngectomy. Post-irradiation complications involved most frequently minor cases of endolaryngeal edema; among the more serious ones were 2 cases of radiation myelitis. The discussion on the problem of radiation dosage in cancer of the larynx, the treatment of regional metastases and combined surgico-radiation therapy.

A retrospective study has been made of the role of intermediate (4500-5000 rads in five weeks) pre-operative radiotherapy in the treatment of advanced carcinoma of the larynx. The results of treatment in 72 cases treated at the University of Virginia have been analyzed with particular attention to local recurrences and complications. The local recurrence rate is comparable to that achieved with higher doses of pre-operative irradiation and the complication rate and the pre-operative level of radiation dose employed. Deaths from causes other than local recurrence indicate that a considerable number of patients die from a second primary or distant metastases even though the local disease has been controlled.

Ours is a developing country. We have still not controlled the common infectious diseases which are extinct in the West; therefore, our limited resources are spent on study of epidemiology of infectious diseases. My conclusions on epidemiology of cancer of the larynx are drawn from observations made of the clinical material over a period of 25 years. I have come to the conclusion that the smoked tobacco and the slaked lime in the Indian "Pan" are the two important carcinogenic agents. Poor nutrition appears to be carcinogenic. It requires study and confirmation at a cellular level. Misuse of voice does seem to be the cause of laryngeal cancer. Racial, genetic and other environmental factors, including pollution have not contributed to the increased incidence of laryngeal cancers. The common histological types of laryngeal cancer are known. My observations on certain biological behavior of the tumor have been helpful. 1. An exophytic growth is less infiltrative; its metastatic mass reflects the same characteristics. 2. Certain anaplastic tumors can flout all laws of cancer spread and metastasize in distal organs. 3. Presence of reticular hyperplasia in peripheral lymph nodes is of good prognostic value.
