  1. 1. Genotoxic effects of systemic chemotherapy in cancer patients, with special focus on the relation between MSI, LOH and development of secondary cancers

    Författare :Nasir K. Kamat; Ulf Rannug; Giovanni Corso; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemotherapy; Genetic instability; Microsatellites instability; Loss of heterozygosity; Mismatch repair; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Systemic chemotherapy results in both phenotypic and genotypic side effects. Genotoxicity posed by chemotherapy is a major concern since it induces DNA damage and instability in the patients’ genome. LÄS MER

  3. 2. Chromosomal Instability and Genomic Amplification in Bone and Soft Tissue Tumours

    Författare :David Gisselsson Nord; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nuclear atypia; kinetochore; anaphase bridge; p53; breakage-fusion-bridge cycle; TP53; HMGIC; MDM2; mitotic instability; genomic instability; FISH; osteosarcoma; liposarcoma; amplification; tumour; chromosome; cytogenetics; Clinical genetics; Klinisk genetik;

    Sammanfattning : Acquired genetic abnormalities are found in all types of malignant tumours and may contribute to neoplastic processes by altering protein structure or dosage. Many bone and soft tissue tumours (BSTT) are characterised by complex patterns of chromosome changes, including extensive intratumour heterogeneity and amplification of DNA sequences. LÄS MER

  4. 3. Genomic instability and genetic heterogeneity in neuroblastoma tumours

    Författare :Niloufar Javanmardi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuroblastoma tumour; subclone; mutation; relapse; deep sequencing; tumour supressor gene;

    Sammanfattning : Neuroblastoma (NB), a tumour of the sympathetic nervous system and the most common malignant disease of early childhood, is responsible for 9% of paediatric cancer related deaths. Aggressive NB still constitutes a major clinical problem with survival rates of about 35%. LÄS MER

  5. 4. Molecular Genetic Alterations In Endometrial And Ovarian Cancers

    Författare :Anjila Koul; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; KRAS; PTEN; TP53; Overexpression; Mutation; Microsatellite instability; Complex atypical hyperplasia; Endometrial cancer; Ovarian cancer; cancer; onkologi; Cytologi; cancerology; oncology; Cytology; CNS metastasis; Cytogenetic analysis; BRCA2; BRCA1; B-catenin; CDKN2A;

    Sammanfattning : Endometrial cancer is the most common gynecological cancer diagnosed in western countries. Complex atypical hyperplasia (CAH) reflects a state of hyperestrinism and its role as a precursor lesion of this cancer is established. LÄS MER

  7. 5. Human papillomavirus infection, genetic instability and invasive properties of cervical lesions

    Författare :Barbro Skyldberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cervical neoplasia; HPV; ISH; PCR; centrosomes; genetic stability; laminin-5;

    Sammanfattning : Cancer of the uterine cervix is one of the most frequent malignancies in women worldwide. Approximately half a million new cases of cervical cancer are diagnosed each year, and about 200 000 women die from the disease. Human papillomavirus (HPV) DNA has been shown to be present in about 90 % of all cervical cancers. LÄS MER
