- Abstract
<bold>Background: </bold>Reports generated from the National Cancer Data Base (NCDB), a joint project of the American College of Surgeons Commission of Cancer and the American Cancer Society, have described trends in demographics, stage, treatment patterns, and survival for a variety of cancers. In this report, the most current (1991) data for ovarian cancer are presented and include some comparisons with 1985/1986 data.<bold>Methods: </bold>Three calls for data from hospital registries across the United States have yielded 17,114 ovarian cancer cases for 1985, 1986, and 1991 combined. These data represent approximately 23%, 23%, and 43%, respectively, of the annual number of cases of ovarian cancer in the United States for those years.<bold>Results: </bold>One-fourth of the reported cases of ovarian cancer were diagnosed in women less than 50 years of age. Younger patients (< 40 years) were more likely to have received conservative therapy (unilateral oophorectomy), consistent with their high prevalence (59%) of Stage I disease. The number of patients reported with an unknown American Joint Committee on Cancer (AJCC) stage decreased from 49% in 1985/1986 to 17% in 1991, although the distribution within stages was unchanged. Increases in important staging procedures were reported in 1991, with threefold increase in the proportion of debulking procedures and a 50% increase in omentectomies accompanying hysterectomy compared with 1985/1986. More advanced disease was reported for those of older age, lower income, African Americans, and patients in smaller hospitals. Relative 5-year survival rates were 74% for patients with Stage I disease, 58% for Stage II, 30% for Stage III, and 19% for Stage IV. Asians and Hispanics presented with a relatively high rate of Stage I-II disease (45%) compared with non-Hispanic whites and African Americans (38% and 33%, respectively). Hispanics presented with the most favorable Stage I/IV ratio (1.5) and had an overall 5-year survival of 50% compared with 41% and 37% for non-Hispanic whites and African Americans (Stage I/IV ratios of 1.0 and 0.7, respectively). There was little difference reported in the use of multimodality treatment between 1985/1986 and 1991.<bold>Conclusions: </bold>A trend toward more complete surgery with full surgical/pathologic staging was observed in 1991, but there was not yet evidence to indicate significant improvements in ovarian cancer survival compared with published figures during the past 10-15 years. Important ethnic and demographic differences in type of surgery and survival were noted but could not be differentiated from differences in tumor stage.
