A population-based survey of histologically diagnosed breast cancer was carried out among residents in Piedmont. A total of 5267 incident cases occurring in 1979-1981 was collected, corresponding to an age-standardized (on the world population) incidence rate of 49.5/100,000 per year. Rates (standardized on the population of Piedmont in 1981) were highest in the city of Torino (112.4/100,000 per year) and lowest in the province of Cuneo (67.5), whereas in the other provinces they ranged between 85.3 and 90.0. Estimation of rates in the 54 Local Health Authorities of Piedmont detected up to 2-fold differences between adjacent areas. A correlation was found between rates and size of the population of town of residence. Comparison with age-specific incidence rates from the Cancer Registry of the nearby province of Varese suggested a loss of nonhistologically confirmed cases selectively in older age groups. The distribution of cases diagnosed in 1979 by histologic type is presented. The proportion of diagnoses reported in terms which were consistent with the 1978 WHO Histological Typing of Breast Tumours was 61.3%. It was highest among cases identified in Pathology Services located in University Hospitals and/or diagnosing more than 50 breast cancers per year.
在皮埃蒙特地区的居民中开展了一项基于人群的组织学确诊乳腺癌调查。共收集了1979年至1981年期间发生的5267例新发病例，对应年龄标准化（以世界人口为标准）发病率为每年49.5/10万。发病率（以1981年皮埃蒙特地区人口为标准进行标准化）在都灵市最高（每年112.4/10万），在库内奥省最低（67.5），而在其他省份，发病率在85.3至90.0之间。对皮埃蒙特54个地方卫生当局发病率的估计发现，相邻地区之间的差异高达两倍。发病率与居住城镇人口规模之间存在相关性。与附近瓦雷泽省癌症登记处特定年龄发病率的比较表明，老年人群中选择性地漏报了非组织学确诊病例。列出了1979年按组织学类型诊断的病例分布情况。报告的诊断比例与1978年世界卫生组织乳腺肿瘤组织学分类一致的为61.3%。在大学医院病理科和/或每年诊断超过50例乳腺癌的病例中，这一比例最高。
