The RARECARE project has proposed a different and more detailed grouping of cancers, based on localisation and histological type, in order to identify rare entities with clinical meaning. RARECARE gathered data on cancer patients diagnosed from 1978 to 2002 and archived in 76 population-based cancer registries, all of which had vital status information(More)
Using red cell phenotyping, cytogenetic analysis of blood lymphocytes, chromosome studies of bone marrow cells, and restriction fragment length polymorphism (RFLP) studies of peripheral blood cells, we demonstrated a high number of mixed chimeras after allogeneic bone marrow transplantation (BMT). Donor marrow from HLA-A, -B, and -DR identical, mixed(More)
Data from the Netherlands Cohort Study on Diet and Cancer were used to investigate the association between anthropometry, energy intake, and physical activity and risk of renal cell carcinoma (RCC). The Netherlands Cohort Study on Diet and Cancer consists of 120,852 men and women aged 55-69 years who completed a self-administered questionnaire at baseline(More)
Twin blood group chimerism seems to be very rare in humans. The 30-40 previously reported cases usually were found by mere coincidence during routine blood grouping in hospitals or blood banks. Usually in these cases frank blood group mixtures of, for example, 50/50%, 25/75%, or 5/95% at most were seen. Smaller percentages are very difficult to notice(More)
Prostate cancer is the most commonly diagnosed cancer in men in Europe and Northern America. Genome-wide association studies (GWAS) have detected an association with markers on chromosome 8q24. Allele -8 of microsatellite DG8S737 with 22 repeats and allele A of the single-nucleotide polymorphism (SNP) rs1447295 have been found to be significantly associated(More)
Biallelic von Hippel-Lindau (VHL) gene defects, a rate-limiting event in the carcinogenesis, occur in approximately 75% of sporadic clear-cell Renal Cell Carcinoma (RCC). We studied the VHL mutation status in a large population-based case group. Cases were identified within the Netherlands cohort study on diet and cancer, which includes 120,852 men and(More)
INTRODUCTION Waiting to start treatment has been shown to be associated with tumor progression and upstaging in head and neck squamous cell carcinomas (HNSCCs). This diminishes the chance of cure and might lead to unnecessary mortality. We investigated the association between waiting times and survival in the Netherlands and assessed which factors were(More)
Blood samples from 31 of 50 consecutive patients receiving bone marrow from an HLA-identical and mixed lymphocyte culture-nonreactive sibling were investigated for the presence of donor and autologous erythrocytes. Simple serological techniques using antigenic differences between donor and recipient and a blood transfusion policy taking these differences(More)
