1. Cytogenetic studies of primary and metastatic breast cancer
Abstract : A series of primary and metastatic breast carcinomas obtained from female and male patients were cytogenetically analysed. Trisomy 12 was identified as a recurrent and sometimes early event in breast carcinogenesis. READ MORE

2. Chronic leukemic B-cell disorders and trisomy 12 : a study of surface markers, protein expression and clinical course
Abstract : Chronic lymphocytic leukemia of B-cell type (CLL) is the most common disease entity of chronic leukemic B-cell disorders (CLBD). CLL is the most frequent leukemia in the Western world and the incidence is increasing. The clinical course is very variable and specific therapy is not always needed. READ MORE

3. Cytogenetic studies of normal kidney tissue and renal cell carcinoma
Abstract : In the present thesis normal kidney tissue and renal cell carcinoma (RCC) were studied by cytogenetic and fluorescence in situ hybridization (FISH) methods to investigate chromosomal aberrations. In the first study, 4 samples of nonneoplastic kidney tissue were cultured for cytogenetic analysis and trisomy 7 was found in all cases in 3-15% of the cells. READ MORE

4. Characterization of somatic mutations in nonneoplastic cells
Abstract : Acquired genetic alterations, of which many are visible on the chromosome level, are believed to be necessary for tumorigenesis, and most tumors display characteristic patterns of recurrent structural and numerical aberrations. However, two of the most frequently occurring chromosome mutations in malignant and benign solid tumors, i.e. READ MORE

5. Chromosome aberrations and environmental exposures in acute leukemia
Abstract : The aims of this thesis are to evaluate the role of environmental exposures, especially professional exposure to organic solvents and petroleum products in the etiology of acute leukemia and to investigate if there is a correlation between the exposure to a specific leukemogen factor and a clonal chromosome aberration of the leukemic cells. Papers I and II present results of a case-control study of environmental exposures, in all occupations during life-time, medical treatments with medicines, chemotherapy and radiation, tobacco-use and the exposure to chemical compounds in private life in 120 patients with acute leukemia and of 120 controls, matched for age (+ 4 years), residence and sex.
