The place of irradiation in the management of the primary lesion in head and neck cancers.

Lesions of the skin are best excised except for specific locations where surgical excision would not likely produce disease-free margins and/or would require extensive plastic repair. A control rate of 90% for T1 lesions and 80% for T2 lesions is obtained with irradiation in the squamous cell carcinomas of the upper respiratory and digestive tract. Heavy smokers and/or severe alcoholics may be preferably treated surgically. The control rates in the T3 and T4 lesions are unsatisfactory with either irradiation or surgery alone. Pre- or postoperative irradiation combined with the appropriate surgical procedure improves the local control rates and to some extent the survival rates. Postoperative irradiation for the highly malignant tumors of the salivary gland reduces the local failure rate from 36% to 11%. The facial nerve can be preserved unless it is grossly involved.

Cervical-pectoral flaps in the treatment of advanced oral cancer.

Twenty-two of 90 patients with carcinoma of the anterior oral cavity treated at the Minneapolis Veterans Administration Hospital from 1965 through 1973 had advanced lesions - tumors attached to the mandible and/or more than 3 cm in size. These patients were treated by primary radical neck dissection, en bloc excision, and segmental mandibulectomy. A cervical-pectoral flap combination was used for reconstruction. The functional and cosmetic results were excellent. Patient survival and cure rate compare favorably with other series. We emphasize the need for wide initial resection with immediate reconstruction.

Head and neck cancer manpower study.

1. Approximately 40,000 cases of cancer of the head and neck (excluding skin) are diagnosed each year. 2. Approximately 20,000 of these cases and 30,000 cases of skin cancer are treated by 366 head and neck cancer surgeons. 3. Ninety per cent of the cases are treated by 63 per cent of the surgeons. 4. Fifty-eight per cent of the surgeons care for between 50 and 300 cases per year. 5. While 2,759 new board-certified surgeons of all specialties are recruited annually to maintain a work force of 46,000 board-certified surgeons (3), apparently 730 potential head and neck cancer surgeons are being prepared to maintain a work force of approximately 450 head and neck cancer surgeons. 6. These findings indicate the need for in-depth study of the manpower needs in head and neck cancer surgery by all who are responsible for the training of surgeons in this field.

Bone scintigraphy: an aid in deciding on the extent of bone resection in malignant oral tumors.

PURPOSE: The decision of whether to perform continuity-sparing or resecting surgery of the jaw in cases of malignant oral tumors is often difficult. PATIENTS AND METHODS: To aid in this decision, bone scintigraphy was evaluated retrospectively in 304 patients with a squamous cell carcinoma. RESULTS: One hundred forty-five patients showed no accumulation of the radionuclide, and none of them had infiltration by tumor histologically. CONCLUSION: It was concluded that a bone-sparing resection of tumors close to the jaw may be justified when there is a negative bone scan.

Important prognostic factors of long-term oropharyngeal carcinoma survivors in Taiwan.

In Taiwan, a clear gender difference emerges for rates of oropharyngeal carcinoma incidence. The purpose of this study was to identify the gender differences and clinical factors associated with oropharyngeal carcinoma survival rates in Taiwan. We analyzed the 5-year survival rates of 8114 subjects diagnosed with oropharyngeal carcinoma between 1987 and 1994. The Cox proportional-hazards model identified clinical characteristics for gender according to oropharyngeal carcinoma death and all-cause death outcomes. The 5-year survival rates were significantly lower for males than females (p < 0.0001). The adjusted hazard ratio of males versus females was 1.54 (95% CI: 1.36-1.74) for oropharyngeal carcinoma death and 1.44 (95% CI: 1.31-1.58) for all-cause death. Gender and other clinical characteristics (i.e. diagnostic age, anatomic site, morphologic type, and treatment modality) play important roles in oropharyngeal carcinoma survival. We suggested that Taiwanese males have high proportion of betel quid chewing and that this is associated with the gender differences.
