Osteosarcoma of the jaw.

The records of 66 patients with osteosarcoma of the jaw were reviewed. The ages of the 42 males and 24 females ranged from 12 to 79 years (mean, 34.2 years). Swelling and pain, the most frequent presenting complaints, were noted an average of three months before the patient was seen by a physician. Fifty-one percent of the lesions involved the maxilla and 49% involved the mandible. The most common sites of involvement were the body of the mandible and the alveolar ridge of the maxilla. Radiologically, most of the lesions in the maxilla were osteoblastic (50%), whereas most of those in the mandible were osteolytic (43%). Chondroblastic osteosarcoma was the most frequent histologic type (48%) and was associated with the best survival rate (47%). Treatment included radical and local surgery with radiotherapy, chemotherapy, or various combinations. The recurrence rate for all treatment modalities was 70%. Patients treated by initial radical surgery had the best survival (80%). Survival decreased to 27% with local surgery. Of the 43 (65%) patients who died, most died with uncontrolled local disease; only four patients had documented distant metastasis, which involved lung, cervical lymph nodes, spinal column, and brain.

Sarcomas of the larynx.

From 1949 to 1974, 17 patients with sarcomas of the larynx were treated at the Mayo Clinic. Histologically, the sarcomas were classified as fibrosarcoma (six tumors), chondrosarcoma (seven tumors), rhabdomyosarcoma (three tumors), and osteosarcoma (one tumor). Patients with chondrosarcomas tended to differ from patients with other sarcomas in respect to origin of the sarcoma and length of survival free of disease.

Reconstruction after total laryngopharyngectomy.

After resection of a hypopharyngeal cancer, utilization of the remaining pharyngeal mucosa in restoring pharyngoesophageal continuity is the procedure of choice. This is possible in most patients. However, a few patients have cancers that involve the posterior pharyngeal wall and esophageal introitus. Resection in this group involves complete removal of a segment of the laryngopharynx and reconstruction with the use of tissue from the adjacent side of the neck, chest, or alimentary canal. Between 1965 and 1974, 44 patients required reconstruction of a pharyngeal defect with the use of adjacent skin flaps or visceral interposition. Pharyngeal reconstruction with the use of these techniques involved multiple operative procedures, a greater morbidity, and a large time investment by the patient and surgeon. Survival of these patients was shorter than survival of patients who had repair by primary closure of the pharyngeal mucosa because of the extent of the primary lesions.

Cellular mixed tumors of the salivary glands.

Mixed tumors are unusual in that they possess both epithelial and mesenchymal elements. The proportions of the two elements vary greatly; the lesions with a pronounced preponderance of epithelial tissue have been called cellular mixed tumors. This increase in epithelial cellularity often results in misdiagnosis or in concern that the tumor may be more aggressive than the ordinary mixed tumor--possibly even malignant. We have reviewed 1,095 consecutive parotid tumors that were removed at the Mayo Clinic, Rochester, Minn, from 1950 through 1970. Ninety-three of the lesions were diagnosed initially as cellular mixed tumors, and slides were available for review. Of these 93, 43 fulfilled our criteria of having greater than 80% of each tumor composed of the packed epithelial cells. All tumors had a corresponding reduction in the mesenchymal portion. The records of the 43 patients were studied to determine the clinical behavior of these neoplasms, particularly with regard to recurrence, metastasis, and malignant transformation. Our findings confirmed our clinical suspicions that some of these cellular mixed tumors, notably those that showed histopathologic evidence of an increased rate of mitotic activity, can and do act in a more aggressive manner.

An immunologic basis for detection of occult primary malignancies of the head and neck.

After extensive evaluation of patients with metastatic neck disease and clinically undetectable primary cancer of the head and neck, the clinician is often faced with the difficult question of subsequent management. In this study, sera from 11 patients with clinically occult carcinoma and metastatic lymphadenopathy were studied for Epstein-Barr virus-associated antigens. These were compared with 35 sera from patients with known nasopharyngeal carcinoma at all stages of disease and treatment and with 212 sera from control patients with other head and neck tumors, patients with lymphoma, and normal controls. There was a significant correlation between high antibody titers to Epstein-Barr virus, especially in the serum IgA fraction, and the presence of nasopharyngeal carcinoma. Thus, identification of occult nasopharyngeal carcinoma by immunologic means may have important application in the selective management of the patient with an unknown head and neck primary malignancy.

Solitary extramedullary plasmacytoma of the larynx.

Plasmacytomas, indistinguishable histologically from plasma cell tumors arising in bone marrow, occur almost anywhere in the body-usually independently of multiple myeloma. Thus, they represent an isolated area of plasmacytic dyscrasia but occasionally can be the first evidence of multiple myeloma. From 1949 to 1974, six patients with solitary extramedullary plasmacytomas of the larynx were seen at the Mayo Clinic; during this period, approximately 3,100 patients with malignant laryngeal neoplasms were examined. For these six patients, the median age was 53 years (range, 32 to 63 years). The first symptom in five patients was hoarseness (mean duration, nine months). Excision, electrocoagulation, irradiation, or some combination of these constituted effective therapy. Follow-up ranged from 3 to 25 years. The choice of therapy depends on the size, shape, and location of the tumor. Extensive surgery is rarely necessary.

Gardner's syndrome and chondrosarcoma of the hyoid bone.

There appears to be a total of five cases of chondrosarcoma of the hyoid bone (not all associated with Gardner's syndrome). The case reported herein is one that was first reported in the literature on Gardner's syndrome and the second reported instance of a patient with Gardner's syndrome who had a malignant bone tumor.

Inverting papilloma of the nose and paranasal sinuses.

Inverting papilloma of the nose and paranasal sinuses has been classified as a true neoplasm by most authors. It is distinct from the ordinary nasal polyps in that it has a different cause, different histologic features, a higher recurrence rate, and is occasionally associated with carcinoma. This study includes 57 patients seen over a 30-year period who had inverting papilloma and for whom the history, clinical and radiologic findings, treatment methods, pathologic sections, and recurrences were analyzed. Features associated with higher recurrence rate were epithelial atypia and extent of lesions. Females showed higher recurrence rates than males. External approaches (lateral rhinotomy) reduced recurrence remarkably compared with transnasal removal (13 percent versus 45 percent). Four patients had associated carcinoma with inverting papilloma, and more extensive operations were perfomred in these cases; one patient died of the tumor. Radical aggressive treatment and careful follow-up are advocated because of the higher recurrence rate after inadequate removal and because of possible malignant transformation.

Verrucous carcinoma of the larynx.

Verrucous carcinoma, because of its oftentimes unusual clinical appearance, may be misdiagnosed if there is not good communication between the surgeon and the pathologist. We have reviewed our series of 20 cases of verrucous carcinoma from 1964 through 1974 and have analyzed the results of our therapy. We have concluded that verrucous carcinoma is a slow-growing, locally invasive lesion that does not metastasize to the cervical lymph nodes. Radiation therapy does not seem to be an effective method of treatment; the recurrence rate is high. Conservative laryngeal surgery is the preferred method of treatment in these patients and should prevent loss of life and spare laryngeal function.

Carcinoma of the supraglottic larynx. A review of 221 cases.

Between 1962 and 1971, 221 patients (197 men and 24 women) with carcinoma of the supraglottic larynx were treated at our institution. Most of the patients were in the sixth and seventh decades of life. In 89% of the patients, the epiglottis was involved. One hundred ninety patients underwent surgery, 161 for cure initially and 29 for salvage after radiation failure. Definitive surgery included laryngectomy in 117 patients and conservation procedures in 40. Fifty-five patients were treated by radiation for cure. Survival rates after laryngectomy or supraglottic laryngectomy were similar, but radiation therapy carried a poorer prognosis than did definitive surgery. Routine neck dissection was not necessary in all patients with supraglottic carcinoma.

Cancer of the hypopharynx. Analysis of treatment and results in 162 patients.

Between 1962 and 1972, 190 patients with squamous cell carcinoma of the hypopharynx were seen; 162 received primary treatment at our clinic. Of the 162 lesions, 117 (72%) originated in the pyriform sinus. The most frequent symptom was pain in the throat (87 patients, 54%). One hundred twenty six patients (78%) had tumors extending beyond the hypopharynx (T3 lesions), and 108 patients (67%) had cervical metastasis (stage III or IV). Treatment modalities included surgical excision in 82 patients, radiation in 39, planned combination of preoperative radiation followed by surgery in 18, radiation plus neck dissection in 15, and surgery plus postoperative radiation in eight. Sixty-nine patients (43%) had recurrent tumor. Recurrences were equally frequent in the primary site and the neck. Comparison of treatment modalities showed no differences in overall recurrence. Surgery alone or in combination with radiation reduced the incidence of local recurrence; however, when recurrences were analyzed in relation to stage of lesion, preoperative or postoperative radiation and surgery offered no advantage over surgery alone in reducing local or neck recurrence or in overall survival rate. Treatment by radiation alone was associated with a poorer survival. For the entire group, three-year survival was 52% and five-year survival was 47%.

Surgical salvage after radiation for laryngeal cancer.

From January, 1962, through December, 1973, 1,084 patients with cancer of the intrinsic larynx were treated at the Mayo Clinic. Of the 1,084 patients, 136 were retreated after radiation therapy failed to cure their cancer (105 glottic, 30 supraglottic, and one subglottic cancers). Recurrence of glottic cancer was generally recognized later than recurrences in the supraglottic area; likewise, glottic cancers were more advanced at recurrence than supraglottic growths. When feasible, conservation surgery was carried out on both glottic and supraglottic growths. Unfortunately, many growths were too advanced for conservation surgery by the time recurrence was recognized. The concept of "radiate-and-watch" for early glottic and supraglottic cancers is designed to save larynges. The concept is not supported by this study.

The protean clinical features of polymorphic reticulosis (lethal midline granuloma).

Confusion surrounds the entity known as "lethal midline granuloma". Partly responsible is the lack of specificity in this term. "Polymorphic reticulosis" has been used as a term to describe the morphology of the disease. Thirty-two cases illustrate the protean features of this disease. Although it commonly presents in the head and neck, other sites such as the lungs, kidneys, skin, and gastrointestinal tract may be involved, either alone or in conjunction with lesions of the head and neck. Clinically, it is easily confused with Wegener's granulomatosis. Histopathologic differentiation, however, is both feasible and important. Wegener's granulomatosis is treatable with steroids with or without cyclophosphamide; polymorphic reticulosis confined to one site responds to irradiation. In polymorphic reticulosis, thhe best results of treatment are obtained in localized lesions of the upper airway treated early with irradiation; a poorer outcome is associated with multifocal involvement, which necessitates systemic therapy.
