Abstract
BACKGROUND
Based on the 1998 Patient Care Evaluation (PCE) from the American College of Surgeons National Cancer Data Base (NCDB), the authors described contemporary nationwide patterns of prostate carcinoma presentation, diagnosis, and staging.
METHODS
The authors reviewed 54,212 cases from the 1998 PCE. Demographics, presenting signs and symptoms, tumor characteristics, prostate biopsy techniques, and use of staging modalities were evaluated.
RESULTS
The mean age of patients in the sample was 68 years. Among patients with available data, 87.5% had a prostate specific antigen (PSA) level of 4 ng/mL or higher, 83.1% had American Joint Committee on Cancer (AJCC) Stage IโII lesions, 80.2% had well or moderately differentiated cancers, and 68.7% of newly diagnosed patients were asymptomatic. Compared with symptomatic patients, asymptomatic patients were more likely to have localized disease (84.6% vs. 78.2%, P < 0.01) and well or moderately differentiated tumors (82.2% vs. 74.6%, P < 0.01). Transrectal ultrasoundโguided prostate biopsy was the most common method of tissue confirmation (45.4%). Radionuclide bone scintigraphy was the most frequently employed staging modality (48.7%). Use of various staging evaluations was more frequent among patients at increased risk for disseminated disease (PSA > 10 ng/mL and/or highโgrade tumors) versus patients at lower risk (PSA โค 10 and low to moderateโgrade tumors) for metastatic disease (P < 0.005).
CONCLUSIONS
Most newly diagnosed patients with prostate carcinoma are asymptomatic and have moderately differentiated and organโconfined disease. Compared with symptomatic patients, tumors in asymptomatic men are associated with lower pretreatment PSA levels, AJCC stage, and tumor grade. Selective use of staging evaluations, based on risk of metastatic disease, may be relatively uncommon. The NCDB remains a unique and rich source of novel patient care information and serves as a national point of reference for prostate carcinoma presentation, diagnosis, and staging.

BACKGROUND. An increase in the proportion of prostate carcinomas diagnosed at early, potentially curable stages has led to several changes in treatment of patients with this disease. Greater use of radical prostatectomy and external beam radiation has been documented, and recent data suggest that th
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" hypo
