BACKGROUND Previous studies of small bowel carcinoid tumours usually presented overall or relative survival. This study, in addition, evaluated disease-specific survival in a cohort of patients in a geographically defined population. METHODS Patients diagnosed with carcinoid of the jejunum or ileum in Jönköping County between 1960 and 2005 were eligible(More)
All cases of adenocarcinoma in the duodenum (n = 263) and jejunum/ileum (n = 663), diagnosed between 1960 and 1988, were recruited from the Swedish Cancer Registry. Corrected and overall survival were investigated by sex, age and year of diagnosis with life-table and Cox proportional hazards analyses. The corrected 5- and 10-year survival rates were 39% and(More)
BACKGROUND Human cytomegalovirus (HCMV) has been implicated as a factor, which might be associated with colorectal cancer (CRC) progression. Data from studies with HCMV-infected tumour cell lines have highlighted an oncomodulatory potential of HCMV. In the present study, we aimed to evaluate the prevalence of HCMV DNA in CRC tissue compared to matched(More)
We studied risk of second malignancies and causes of death in 1829 cases of adenocarcinoma and 3055 cases of carcinoid tumours in the small bowel reported to the Swedish Cancer Registry from 1960 through to 2000. Data on causes of death were analysed as from 1966 whereas data on second tumours was available during the whole registry-period. Follow-up was(More)
AIM The main aims were to explore time trends in the management and outcome of patients with rectal cancer in a national cohort and to evaluate the possible impact of national auditing on overall outcomes. A secondary aim was to provide population-based data for appraisal of external validity in selected patient series. METHOD Data from the Swedish(More)
Chemokines (chemotactic cytokines) promote leukocyte attraction to sites of inflammation and cancer. Certain chemokines promote and regulate neoplastic progression, including metastasis and angiogenesis. One such chemokine, CXCL10, was found to be expressed in colorectal cancer (CRC) tissue. To gain insight into the prognostic significance of CXCL10, we(More)
Interleukin-8 (IL-8) also referred to as CXCL8, a member of the CXC chemokine family that attracts neutrophils and other leukocytes, has been associated with cancer. Angiogenesis is a prime regulator of tumour expansion and data support that IL-8 is a potent angiogenic factor. Epigenomic instability has been postulated to play a role for the development of(More)
Recent studies have revealed participation of chemokines in cancer by regulating leukocyte movement to modify local immunoresponse. The chemokine CCL21 has been identified to play a pivotal role in homing and localization of immune cells to lymphoid tissue and into organ of non-lymphoid origin. In the cancer biology CCL21 seems to have multifaceted roles.(More)
BACKGROUND Mitochondrial DNA (mtDNA) has been proposed to be involved in carcinogenesis and aging. The mtDNA 4977 bp deletion is one of the most frequently observed mtDNA mutations in human tissues and may play a role in colorectal cancer (CRC). In the present study, we aimed to evaluate the frequency of mtDNA 4977 bp deletion in CRC tissues and its(More)
Pigment epithelium-derived factor (PEDF) is a potent inhibitor of angiogenesis and has been proposed to be a tumor suppressor in a variety of tumors. Limited reports exist of PEDF in colorectal cancer (CRC). We noted a 55% lower plasma level (p < .001) of PEDF in the CRC patient group (1.6 μg/mL) than in of a healthy control group (3.6 μg/mL). A single(More)
