  2. 1. Computational studies of mutational sequence signatures in cancer genomes

    Author : Markus Lindberg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; Genomcis; Mutational signatures; Ultraviolet light; Multifocal tumors;

    Abstract : Cancer typically forms when mutational processes modify key cancer driver genes, resulting in positive selection and tumor growth. As such, mutational processes are at the core of the disease. Trinucleotide mutational signatures have emerged in the last decade as essential tools for analysis of mutational processes. READ MORE

  4. 2. Genetic Characterization and Identification of Novel Treatment Targets in Anaplastic Thyroid Carcinoma

    Author : Naveen Ravi; Avdelningen för klinisk genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaplastic thyroid cancer; copy number alterations; somatic mutations; mutational signatures; DNA methylation analysis; Gene expression analysis;

    Abstract : Anaplastic thyroid cancer (ATC) is a rare and highly aggressive thyroid malignancy, usually resistant to conventional therapeutic strategies. The prognosis of ATC is extremely poor with a median survival rate of 6 months. Current treatment therapy includes surgical resection in combination with external radiotherapy and chemotherapy.

  5. 3. The leukocyte complexity and mutational landscape of periampullary adenocarcinoma. Morphology matters

    Author : Sebastian Lundgren; Tumörmikromiljö; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; periampullary adenocarcinoma; pancreatic cancer; immune microenviroment; prognosis; macrophages; natural killer cells; natural killer T cells; T cells; B cells;

    Abstract : Background: Periampullary adenocarcinomas are a heterogenous group of tumours with poor prognosis that hasnot improved considerably the last decades. Tumour morphology, i.e. intestinal type (I-type) or pancreatobiliarytype (PB-type), has been demonstrated to be a more relevant prognostic factor than anatomical origin. READ MORE

  6. 4. Characterization of the genome and tumor microenvironment of human B-cell lymphoma

    Author : Xiaofei Ye; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Non-Hodgkin lymphoma (NHL) is the 13th most common type of cancer worldwide in 2020 and consists mainly of human B-cell lymphoma (approximately 85%). Diffuse large B-cell lymphoma (DLBCL) is the most common NHL subtype (approximately 30%). READ MORE

  7. 5. Genetic and molecular mechanisms of sarcomas

    Author : Yi Chen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Sarcomas are heterogeneous malignant mesenchymal tumors with diverse biological features and unique clinical characteristics, the genetic alterations of sarcomas are highly variable. With the development of sequencing technologies, efficient and practical approaches to detect gene expressions and gene variants contribute to the prediction of patient prognosis and the choice of treatment modalities.
