PURPOSE To describe the history, clinical findings, and possible etiologies of ophthalmic findings discovered in 7 astronauts after long-duration space flight, and document vision changes in approximately 300 additional astronauts. DESIGN Retrospective, observational examination of ophthalmic findings in 7 astronauts and analysis of postflight(More)
BACKGROUND A high proportion of U.S. patients with gastric carcinoma do not receive surgical treatment. To sharpen staging criteria and facilitate comparisons with surgical series, an analysis of patients whose treatment included gastrectomy was undertaken. In addition, to evaluate the "different disease" hypothesis as an explanation for superior Japanese(More)
BACKGROUND This study was conducted to determine practice patterns in the management of vaginal malignancy. METHODS The National Cancer Data Base (NCDB), a large central registry of hospital case data, was reviewed for the 10-year period 1985-1994 for patients registered with a primary diagnosis of vaginal cancer. Patients with a prior history of(More)
Measurement of gene-expression profiles using microarray technology is becoming increasingly popular among the biomedical research community. Although there has been great progress in this field, investigators are still confronted with a difficult question after completing their experiments: how to validate the large data sets that are generated? This(More)
Here we report the genetic characterization of immortalized prostate epithelial cells before and after conversion to tumorigenicity using molecular cytogenetics and microarray technology. We were particularly interested to analyze the consequences of acquired chromosomal aneuploidies with respect to modifications of gene expression profiles. Compared with(More)
In primary hyperaldosteronism, discriminating bilateral adrenal hyperplasia (BAH) from an aldosterone-producing adenoma (APA) is important because adrenalectomy, which is usually curative in APA, is seldom effective in BAH. We analyzed the results from our most recent 7-yr series to evaluate the predictive value of preoperative noninvasive tests compared(More)
BACKGROUND Primary lung cancer accounts for approximately 14% of all new cancers and 28% of cancer deaths in the U.S. Previous reviews have shown limited progress in the management or outcome of this devastating disease. METHODS Reports described in the current study were 713,043 primary lung malignancies diagnosed between 1985 and 1995 and submitted to(More)
BACKGROUND Epithelial ovarian cancer continues to challenge clinicians. There is no accepted method of screening for ovarian cancer, and most patients present with advanced disease. In spite of advances in surgery and chemotherapy, survival continues to be poor. METHODS The data, comprising the ovarian cancer caseloads of 940 hospitals, are from the(More)
BACKGROUND The development of nasopharyngeal carcinoma reflects interactions of genetics, diet, and viral agents. It is more common in Asians than non-Asians, with different characteristic histologic types. This study examined nasopharyngeal carcinoma in the U.S. as a function of patient origin and histology. METHODS The data were from the National Cancer(More)
BACKGROUND Although the incidence of uterine carcinoma is lower among African-American women compared with white women, the mortality rates are higher for African-American patients. This report is part of an ongoing series on gynecologic malignancies in African-American women. METHODS Hospital registry reports collected by the National Cancer Data Base(More)
