    • The centrosome is the main microtubule-organizing center in human cells. It regulates normal cell-cycle progression and cell division. Aberrations in the number, structure and function of centrosomes have been found to drive genomic instability and tumorigenesis. Pancreatic cancer frequently displays centrosomal aberrations. Supernumerary and abnormal centrosomes are observed in the earliest stages of pancreatic tumor development, and the p53 pathway acts as an initial barrier to the proliferation of cells with extra centrosomes. In this review, we summarize recent advances in the understanding of centrosomal aberrations in pancreatic cancer, focusing on regulatory mechanisms and prospects for future anticancer treatment.

    • Hippo signaling is a key regulator of organ size, tissue hemostasis and regeneration. Dysregulation of the Hippo pathway has been recognized in a variety of human cancers, including pancreatic cancer. YES-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ) are the two major downstream effectors of the Hippo pathway. YAP and TAZ have been found to promote pancreatic tumor development and progression, even in the absence of mutant Kirsten RAS (KRAS). Pancreatic cancer is associated with an abundant stromal reaction leading to tumor growth and immune escape. It has been found that YAP and TAZ modulate behavior of pancreatic stellate cells and recruitment of tumor-associated macrophages and myeloid-derived suppressor cells. Moreover, YAP and TAZ are associated with chemoresistance and poor prognosis in pancreatic cancer. This review dissects the role of Hippo signaling in pancreatic cancer, focusing on molecular mechanisms and prospects for future intervention.

  • The role of PEDF in pancreatic cancer
  • 2019
  • Ingår i: Anticancer research. - : Anticancer Research USA Inc.. - 0250-7005 .- 1791-7530. ; 39:7, s. 3311-3315

    • Pigment epithelium-derived factor (PEDF) is an important antiangiogenic and antitumorigenic factor in a variety of cancer forms, including pancreatic cancer. PEDF is mainly secreted as a soluble monomeric glycoprotein. In human pancreatic cancer PEDF levels are decreased, both in the tissue and serum. The decrease is associated with increased tumor angiogenesis, fibrosis, inflammation, autophagy, occurrence of liver metastasis and worse prognosis. In murine models, loss of PEDF is sufficient to induce invasive carcinoma and this phenotype is associated with large lesions characterized by poor differentiation. Lentiviral gene transfer of PEDF has resulted in decreased microvessel density and has inhibited tumor growth. Herein we review the multifunctional role of PEDF in pancreatic cancer and its therapeutic potential.

  • Randomized Trials of Systemic Medically-treated Malignant Mesothelioma : A Systematic Review
  • 2015
  • Ingår i: Anticancer Research. - 0250-7005 .- 1791-7530. ; 35:5, s. 2493-2501

    • Malignant pleural mesothelioma (MPM) is a rare but aggressive malignancy mainly localized to the pleura. Malignant mesothelioma grows highly invasive into surrounding tissue and has a low tendency to metastasize. The median overall survival (OS) of locally advanced or metastatic disease without treatment is 4-13 months but, during recent years, improvement in survival has been achieved since treatment for patients with mesothelioma has improved with better palliative care, systemic medical treatment, surgery and improved diagnostics methods. The present review aims at describing available data from randomized trials considering systemic medical treatment for this patient category.

  • Complete Lymph Node Dissection in Melanoma : A Systematic Review and Meta-Analysis
  • 2017
  • Ingår i: Anticancer Research. - : Anticancer Research USA Inc.. - 0250-7005 .- 1791-7530. ; 37:12, s. 6825-6829
  • Forskningsöversikt (refereegranskat)abstract
    • Background: The aim of this meta-analysis was to estimate the survival after immediate complete lymph node dissection (CLND) compared to observation only (OO) or delayed CLND in patients with melanoma and lymph node metastasis.Materials and Methods: A systematic search was performed in: PubMed, Web of Science, Cochrane Library, CINAHL, Clinical trials and Embase. Eligible studies were randomized controlled trials (RCTs) comparing: CLND with OO, or immediate CLND with delayed CLND.Results: Four RCTs were included. There was no difference in melanoma-specific survival (MSS) (HR=0.91, 95% CI=0.77-1.08, p=0.29). In a sensitivity analysis, MSS was higher after immediate CLND compared to delayed CLND in patients with nodal metastasis (HR=0.63, 95% CI=0.35-0.74, p=0.0004) without evidence of heterogeneity.Conclusion: CLND appears to have no additional survival benefit after SNB compared to OO. However, subgroup analysis suggests a time-dependent benefit for early surgical lymph node removal compared to delayed or none.

    • Cancer in the oral cavity is often preceded by precursor lesions. Nine oral mucosal disorders are known to have an increased risk of malignant transformation. The etiology varies from disorders caused by exogenous factors such as tobacco and autoimmune inflammation to idiopathic or inherited genetic aberrations. In this review, these potentially malignant disorders (PMDs) are described regarding clinical presentation and histopathological architecture. Special attention is paid to the underlying etiologies of PMDs and the potential pathways leading to cancer. The clinical perspective focuses on the importance of accurate and timely diagnosis.

  • Microsatellite instability as a prognostic factor in stage II colon cancer patients : a meta-analysis of published literature
  • 2017
  • Ingår i: Anticancer Research. - : Anticancer Research USA Inc.. - 0250-7005 .- 1791-7530. ; 37:12, s. 6563-6574
  • Forskningsöversikt (refereegranskat)abstract
    • BACKGROUND/AIM: The prognostic role of microsatellite instability (MSI) in stage II colon cancer patients remains controversial despite the fact that it has been investigated in a number of studies. Hazard ratios differ considerably among these studies. We performed a meta-analysis to define the significance of MSI in this group of patients.MATERIALS AND METHODS: Studies indexed in PubMed presenting separate data on MSI status and survival outcomes for stage II colon cancer patients have been analyzed using fixed-effect meta-analysis of hazard ratio (HR) according to the method of Peto.RESULTS: Analysis was performed on 19 studies including 5,998 patients. A 47.3% of patients received postoperative chemotherapy and included 52.8% males and 47.2% females. Eight studies included some rectal cancer patients although this cohort was not clearly defined in 3 of these. MSI observed in 20.8% (mean) of patients (median 19.9%). HR for overall survival (OS) of MSI vs. microsatellite stable (MSS) tumors for the entire population: 0.73 (95% confidence interval (CI)=0.33-1.65); HR for disease-free survival (DFS):0.60 (95%CI=0.27-1.32). No statistical significant difference was found when studies analyzing MSI with genotyping (MG) and immunohistochemistry (IHC) were compared separately (MG vs. IHC: HR OS 0.45, 95%CI=0.10-2.05 vs. 0.95, 95%CI=0.57-1.58; HR DFS 0.51, 95%CI=0.14-1.85 vs. 0.67, 95%CI=0.26-1.70). However, numerically MSI determination with genotyping shows significantly lower hazard ratios for both DFS and OS. Separate analysis of studies describing colon cancer patients only showed HR OS 0.72 (95%CI=0.31-1.71); HR DFS 0.60 (95%CI=0.27-1.31).CONCLUSION: No significant relation was found between MSI status and OS or DFS. Routine determination of MSI status to guide postoperative management of stage II colon cancer patients cannot be recommended. New large scale high quality studies are needed to answer this question definitively, since currently analyzed studies vary considerably.

  • The Emerging Role of Calcium-activated Chloride Channel Regulator 1 in Cancer
  • 2019
  • Ingår i: Anticancer research. - : Anticancer Research USA Inc.. - 1791-7530 .- 0250-7005. ; 39:4, s. 1661-1666
  • Forskningsöversikt (refereegranskat)abstract
    • Calcium-activated chloride channel regulator 1 (CLCA1) belongs to a group of secreted self-cleaving proteins, which activate calcium-dependent chloride channels. CLCA1 has been shown to participate in the pathogenesis of inflammatory airway diseases such as asthma. Recently, additional functions of CLCA1 have been unveiled, including its metalloprotease property and involvement in mucus homeostasis and immune modulation. Emerging evidence suggests that CLCA1 may also be involved in the pathophysiology of colorectal, pancreatic and ovarian cancer. There is growing interest in utilizing CLCA1 as a diagnostic, prognostic and predictive biomarker, as well as a potential therapeutic target. In this review, the functional role of CLCA1, with a particular focus on cancer, is described.

  • The Use of Complementary and Alternative Medicine in Scandinavia
  • 2016
  • Ingår i: Anticancer Research. - 0250-7005 .- 1791-7530. ; 36:7, s. 3243-3251
  • Forskningsöversikt (refereegranskat)abstract
    • Background: Complementary alternative medicine (CAM) is widely used among patients with cancer. This usage may have potentially harmful effects, especially when combined with anticancer drugs. However, some complementary methods may benefit patients. This review investigated the prevalence of CAM use among patients with cancer in Scandinavia and secondly studied the educational levels of CAM users compared to non-users. Materials and Methods: A systematic search of the PubMed library was carried out to locate articles published between January 2000 and October 2015 that investigated prevalence of CAM use among Scandinavian patients with cancer. Results: Twenty-two articles were found, of which nine were included in the review. The prevalence of CAM use was 7.9% to 53%, with an average of 36.0% across all studies. Conclusion: Use of CAM is widespread among patients with cancer. Knowledge about CAM should be disseminated to both patients and staff in order to optimise discussions about CAM in clinical practice.

  • Human Papillomavirus and Potentially Relevant Biomarkers in Tonsillar and Base of Tongue Squamous Cell Carcinoma
  • 2017
  • Ingår i: Anticancer Research. - : International Institute of Anticancer Research. - 0250-7005 .- 1791-7530. ; 37:10, s. 5319-5328
  • Forskningsöversikt (refereegranskat)abstract
    • Human papillomavirus (HPV)-positive tonsillar- and base of tongue cancer is increasing epidemically and has much better outcome than corresponding HPV-negative cancer and most other head and neck cancers with around 80% 3-year disease free survival with conventional radiotherapy and surgery. Consequently, most HPV-positive cancer patients may not require the intensified chemoradiotherapy given to many head and neck cancer patients and would, with tapered treatment, avoid several severe side-effects. Moreover, intensified therapy has not improved survival and treatment alternatives are needed. To identify patients eligible for tapered or targeted therapy, additional biomarkers are required. Several studies have, therefore, focused on finding predictive markers, some of which are also potentially targetable. To conclude, better-tailored therapy, either as tapered or targeted, is important for increasing numbers of patients with HPV-positive tonsillar- and base of tongue cancer. This review deals with some of these issues and presents some promising markers.
