11. Heterogeneity and biopsy strategies in prostate cancer
Sammanfattning : For the diagnosis of prostate cancer, there is a need to develop biopsy strategies, that give representative information both for detection of cancer and for assessment of prognostic indicators.In 80 men, transrectal core biopsies from 10 standardized positions were taken before radical prostatectomy.

12. Growth factor signaling in the breast tumor microenvironment
Sammanfattning : Cancer represents a collection of malignancies characterized by an aberrant expansion of cells. This unrestrained growth is the result of the acquisition of several pro-survival features and the evasion of cellular fail-safe mechanisms, collectively known as the hallmarks of cancer. LÄS MER
13. Exploring mechanisms regulating the heterogeneity of tumor-associated macrophages
Sammanfattning : Accumulation of macrophages in the tumor microenvironment is associated to poor prognoses in most human cancers. Tumor-associated macrophages (TAMs) represent a heterogeneous and plastic population of cells that contribute to tumor growth, metastatic dissemination, angiogenesis, and immune suppression. LÄS MER
14. Soft Tissue Sarcoma Patterns multiplicity, heterogeneity and growth characteristics
Sammanfattning : Soft tissue sarcomas (STS) represent a group of rare and heterogenous tumors that optimally should be diagnosed and treated within multidisciplinary teams. This thesis has studied various aspects ? pathological, genetical, and clinical ? of STS. LÄS MER
15. Molecular mechanisms involved in glioma cell interactions in vitro and studies of PDGF B transcript variants
Sammanfattning : Glioblastoma multiforme is a malignant brain tumor characterized by heterogeneity.Interactions between heterogeneous tumor cells are supposed to affect the behavior of awhole tumor cell population. LÄS MER
