ABSTRACT
PURPOSE:
To analyze the results of round 1 of the population-based Valencia Breast Cancer Screening Program. MATERIALS ANDMETHODS:
In this program, 78,224 (72.98%) of the 107,178 women invited (aged 45-65 years) underwent screening. Complementary views were obtained in 5,771 women (7.38%). Among the total population studied, 3,502 (4.48%) underwent short-term mammographic follow-up studies; 3,898 (4.98%) underwent additional studies and treatment at hospitals. Five hundred eighty-seven women (0.75%) underwent biopsy.RESULTS:
Cancer was detected in 334 patients (4.27 cancers per 1,000 women [3.24 per 1,000 women aged 45-49 years, 6.30 per 1,000 women aged 60-65 years]; six patients with lobular carcinoma in situ excluded). The estimated sensitivity was 89%; specificity, 99%. The positive predictive value of mammography was 8.56%; of mammography with additional examinations, 26.82%; and of biopsy, 56.89%. Forty-one patients (12.28%) had ductal carcinoma in situ; 284 (85.03%) had infiltrating carcinoma. In 73 (25.70%) of the 284 patients, infiltrating carcinomas were smaller than 1 cm. Two hundred twenty-five patients (76.27%) had no lymph node involvement. One hundred seventy-nine (61.09%) had stage 0 or 1 cancer.CONCLUSION:
Results are consistent with other published results; differences are due to methods and patient population characteristics.
