BACKGROUND Most patients with glioblastoma are older than 60 years, but treatment guidelines are based on trials in patients aged only up to 70 years. We did a randomised trial to assess the optimum palliative treatment in patients aged 60 years and older with glioblastoma. METHODS Patients with newly diagnosed glioblastoma were recruited from Austria,(More)
There is strong evidence that cancer-associated inflammation promotes tumor growth and progression. This is especially true for colorectal cancer (CRC). Interleukins (ILs) are important modulators for inflammation. We examined whether promoter polymorphisms in key IL genes (IL4, IL4R, IL6, IL8 and IL10) are associated with the risk or clinical outcome of(More)
In a previous study, a decreased risk for first degree relatives of patients with astrocytoma has been observed for breast and colorectal cancer. The aim of this study was to examine the associations between breast and colorectal cancer as first primary cancer and the risk of developing astrocytoma and meningioma as a second primary cancer. Two cohorts were(More)
Objectives: The aim of the study was to investigate whether factors of pregnancy and birth influence the risk of malignancy in the offspring. Methods: Data on all deliveries (248,701 births) in two counties in Sweden 1955–90 were extracted from two birth registries. The follow-up period closed at the end of 1994 and the subjects were followed up to early(More)
Transforming growth factor beta1 (TGFB1) acts as a growth inhibitor of normal colonic epithelial cells, however, as a tumor promoter of colorectal cancer (CRC) cells. To explore the association between genetic polymorphisms in the TGFB1 pathway and CRC susceptibility and clinical outcome, we carried out a case-control study on a Swedish population of 308(More)
The angiogenic factor vascular endothelial growth factor (VEGF) predicts outcome in primary breast carcinoma. Alteration of the p53 gene causes down-regulation of the expression of thrombospondin-1, a natural inhibitor of angiogenesis. This study was conducted to investigate the association between mutant p53 protein and VEGF expression, and the prognostic(More)
Telomeres are essential for maintaining chromosomal stability. Previous studies have indicated that individuals with shorter blood telomeres may be at higher risk of developing various types of cancer, such as in lung, bladder, and kidney. We have analyzed relative telomere length (RTL) of peripheral blood cells in relation to breast cancer incidence and(More)
Epidemiological data from the Swedish Cancer Registry of new cases of malignant major and accessory salivary gland tumors in Sweden between 1960 and 1989 are presented, including the total number and the age-standardised incidence rate per 1 million population, by site and sex, I(s). An analysis of the various histopathological types of malignant salivary(More)
The aim of this study was to investigate possible associations between the expression of c-erbB-2 and the angiogenic factors vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), p53 status, routine breast cancer prognostic factors and survival. Expression of c-erbB-2, VEGF, bFGF, and p53 protein was determined with an(More)
PURPOSE The aim was to investigate the significance of lymph node micrometastases in Dukes Stages A and B colorectal cancer. METHODS Archival specimens were examined from 147 patients (96 colon, 51 rectum; 44 Stage A, 103 Stage B) who had surgery between 1987 and 1994. One lymph node section from each node (colon, 1-11; median, 4; rectum, 1-15; median, 3)(More)
