Salivary tumors of the base of the tongue are encountered infrequently. A retrospective review of medical records from 1955 to 1985 was undertaken to determine the incidence of occurrence and to assess the outcome of the therapy provided. One hundred seventy-eight minor salivary gland tumors of the oral cavity and oropharynx were identified, of which 22 (13%) were located in the tongue base. All were malignant. The most common histologic type was mucoepidermoid carcinoma (10 patients), followed by adenocarcinoma (6 patients), and adenoid cystic carcinoma (6 patients). Thirteen patients were available for a mean follow-up of 5 years. Treatment was most often a combination of wide resection combined with postoperative radiation therapy. Ten patients (77%) are alive, one with persistent disease 8 years after diagnosis. Three patients died within 2 years of diagnosis, one with intercurrent disease. Improved control of disease in this series, when compared to previously reported series, is attributed to adequate surgical therapy and adjuvant radiotherapy. The deaths in our series occurred in patients who were unable to proceed with the recommended therapy. These unusual lesions require aggressive multimodality treatment for improved survival.
Studies undertaken at the Eye and Ear Hospital of Pittsburgh indicate that antibiotic prophylaxis can reduce the incidence of patient morbidity. In this article we will demonstrate the effect of antibiotic prophylaxis on the economics of major head and neck surgery. One hundred and one patients were assigned to one of four treatment protocols, three of which entailed 1 day of a perioperative prophylactic antibiotic and the fourth a placebo. The study was conducted in a double-blind, randomized fashion. Patients receiving a placebo experienced an infection rate of 78%. Patients receiving cefazolin experienced an infection rate of 33%. Ten percent of patients treated with cefoperazone or cefotaxime developed postoperative wound infection. Postoperative hospitalization averaged 17.9 days for patients who did not develop postoperative wound infection, in contrast to an average of 32.6 days for patients with postoperative would infection. The added cost of postoperative infection justifies the added use of the newer, more expensive antibiotics in view of the reduced postoperative morbidity and postoperative hospitalization.
Mixed squamous and oat cell carcinomas (composite neoplasms) of the larynx behave aggressively with a propensity toward early dissemination. Diagnosis may not be made until definitive surgery is performed. The extent of surgery must be determined by the size and site of the primary neoplasm and the physiologic status of the patient. In our experience, surgery has adequately controlled the primary disease. A metastatic work-up is essential. Entry into a comprehensive program employing adjunctive radiotherapy and chemotherapy are strongly recommended. Theories concerning histogenesis remain controversial and include two separate colliding tumors, differentiation from a single cell line, or divergent differentiation of a single cell line.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
