ORAL-CANCER - A SURVEY OF 566 CASES FROM THE UNIVERSITY-OF-CONNECTICUT ORAL PATHOLOGY BIOPSY SERVICE, 1975-1986

A survey of the University of Connecticut Oral Pathology Biopsy Service was undertaken to analyze cases of oral cancer accessioned during the 12-year period, 1975 through 1986 inclusive. Of 33,429 total specimens accessioned, there were 546 malignant oral neoplasms diagnosed and reported. Sixty-five (11.5%) originated from out of state. Invasive intraoral squamous cell carcinoma was the predominant tumor (69.7% of total), whereas lip cancer constituted only 2.8% of all malignancies. Minor salivary gland adenocarcinomas accounted for 11% of total malignancies whereas verrucous carcinoma, carcinoma in situ, and miscellaneous other forms of oral cancer accounted for the remainder (4.6%, 5.3%, and 6.6%, respectively). Cases of invasive squamous cell carcinoma were further analyzed by year, sex distribution, location subsite, age at diagnosis, and histologic grade. With the exception of histologic grading, we found that the characterization of cases of squamous cell carcinoma within the biopsy service tended to parallel results from a separate but related statewide analysis of both oral cancer and intraoral squamous cell carcinoma from Connecticut over a much longer time span. We concluded that the picture of oral cancer as characterized by cases within the University of Connecticut Oral Pathology Biopsy Service is generally reflective of the disease on a statewide level. © 1990.
