โœฆ Synopsis

Background. Carcinoma of the gingivobuccal complex is commonly associated with the use of smokeless tobacco known as ''quid.''

Methods. We conducted a retrospective chart review of 511 patients with advanced cancer of gingivobuccal complex surgically treated during 1994 to 1995. We evaluated patterns of disease failure in these patients and correlated disease-free survival with various prognostic factors.

Results. During a median follow-up of 46 months, 159 locoregional recurrences and 11 distant metastases were detected in 148 patients. Seventy-nine percent of the recurrences appeared within 18 months of surgery, and the median survival for patients with recurrent disease was less than 4 months. Two-year and 5-year disease-free survival rates were 64% and 57%, respectively. On multivariate analysis, disease-free survival showed significant correlation with skin involvement and extracapsular spread.

Conclusions. Gingivobuccal cancers usually fail locoregionally. Soft tissue infiltration and extracapsular spread of nodal dis-ease influence disease-free survival.

The patterns of spread of squamous cell carcinoma within the mandible were investigated in 43 nonirradiated (33 edentulous and 10 partially dentate) and 16 irradiated mandibles. Two modes of spread were identified: (1) spread in relation to the inferior alveolar nerve, and (2) spread in spaces betwe

Early carcinomas of the lip are usually straightforward in their management and outcome. The exceptions can result in severe morbidity. A 32-year-old man underwent a V-lip excision for a T1 squamous cell carcinoma of the left lower lip 2 years ago. All margins were free of tumor. He has had irregul
