[Histological diagnosis and therapy of rare breast neoplasms].

Occasional rare benign and malignant breast tumours present diagnostical difficulties, how a report on 8 rare forms of tumours among 564 breast rumors (351 benign, 213 malignant) of the years 1965--1972 at the Universitäts-Frauenklinik Greifswald shows. We found among 351 benign breast tumours 2 rare forms: 1 tubular adenoma and 1 nodular lymphoreticulosis. We diagnosed among 213 malignant breast tumours 6 rare tumour-types: one at a case an unilateral respectively a bilateral noninvasive lobular carcinoma from the carcinoma-in-situ-type, 1 spindlecell- and 2 reticulosarcoma, which in one case the starting-point of the heterogeneous differentiated reticulosarcoma was obvious situated in a teratoid tumour. Last case dealt with a real cystosarcoma phylloides, of which oncological and terminological problems were additional discussed.

Immunoreaction at 43 kDa with anti-ubiquitin antibody in breast neoplasms.

Protein ubiquitination has been implicated in ATP-dependent protein turnover and normal cell proliferation. To investigate whether the ubiquitin-mediated system is functionally involved in the cancerous state, we examined changes in protein ubiquitination in 52 surgically resected primary breast tumors. Immunohistochemically, ubiquitin (Ub) was identified in the cytoplasm of cancer cells, which were stained more strongly than adjacent normal ductal epithelium. Corresponding immunoblot analysis of normal and neoplastic regions of human breast showed that the immunoreaction for Ub at about 43 kDa was increased in all of the tumors (100%), regardless of the clinical stage or histologic grade. This protein, which gave a single spot on two-dimensional gel electrophoresis, had partial amino acid sequences which were identical to those of actin family members. Our results suggest that ubiquitination of this 43-kDa protein may be involved in the carcinogenesis or biological characteristics of human breast neoplasms.

An image cytometric DNA-analysis in breast neoplasms. Parameters of DNA-aneuploidy and their relationship with conventional prognostic factors.

In this prospective study, an image cytometric DNA-analysis was performed in 86 women with breast neoplasms (72 primary invasive carcinomas and 14 benign lesions). Four DNA ploidy parameters were analysed: histogram type (according to AUER classification), DNA-index, tumor cells with DNA content above the 5n limit and DNA malignancy grade (DNA-MG, calculation according to Böcking). Their correlations with well established prognostic factors in breast carcinomas (tumor size, lymph node status, histologic grade, hormone receptor content) were studied. All but one benign lesions were diploid (13/14 cases), whereas the majority of the primary invasive breast carcinomas were aneuploid (58/72 cases). A predominance of carcinomas with a percentage of cells superior or equal to 1% with DNA content above the 5n limit was observed (54 cases out of 58). Most of the aneuploid tumors had a histogram type III or IV (53 cases) or a high DNA-index (50 cases). Of these 58 aneuploid cases, only 26 tumors had a DNA-MG superior to 1. Interestingly, 26 tumors had the 4 criteria of aneuploidy, 19 had 3 and 9 had 2 and only 4 tumors had one parameter. The DNA-MG was significantly related to hormonal receptors (p less than 0.001) and tumor size (p less than 0.01). The histogram types (Auer classification) and the DNA content above the 5n limit were correlated with histologic grade (SBR or SBRM) (p less than 0.02). Concerning the DNA-index no correlation was observed with well established prognostic factors. On the other hand no significant correlation was found between these new biologic variables and lymph node status.(ABSTRACT TRUNCATED AT 250 WORDS)

The effect of screening programmes on the treatment of benign breast neoplasms: observations from current practice in Italy.

PURPOSE: In the Lazio region, Italy, mammographic screening programmes were gradually activated from 1999 to 2003, providing an opportunity to compare two unselected populations in the same time period: women who were contacted in writing, and those who had not been contacted. In this study, we compare the incidences of treatments for benign and malignant neoplasms in the two groups. METHODS: The target population was women aged 50-69 years. We linked all incident cases of surgery for benign and malignant breast neoplasms, from the Hospital Information System (1999-2003) to the Mammographic Screening Information System (1999-2001). We calculated incidence, adjusted for age and standardized breast cancer mortality ratio in each area of residence, for benign and malignant neoplasms surgery in non-yet-contacted and contacted woman. Incidence for contacted women was calculated for the two years following initial contact. RESULTS: The target population in Lazio is 681,000; 116,000 women were contacted during the study period and 3252 malignant and 1566 benign neoplasms were surgically treated. Annual incidence was, respectively, 2.0/1000 and 1.1/1000 for malignant and benign neoplasms in women not contacted, and, respectively, 2.9/1000 and 1.1/1000 in the contacted population. Among the contacted group, annual incidence was 4.3/1000 and 1.5/1000 in compliant women, and 2.0/1000 and 0.9/1000 in non-compliant women. About one-half of the surgeries for benign neoplasms in compliant women were treated against the recommendation of the screening programme. CONCLUSIONS: The implementation of the screening programme did not increase the incidence of treatment for benign neoplasms, and detected 50% more malignant neoplasms.
