The study's aim was to ascertain whether living alone is associated with the use of an independent cancer information service. An Enquirer Record Form is completed for every fifth enquirer to the service; two questions asking whether enquirers, patients, relatives/friends were living alone or with others where asked in association with the routine questions. A total of 552 callers were asked in a 5-week period, 77% of all callers in these categories. The main findings were: (1) the proportion of enquirers living alone was similar to the general population; (2) among enquirers, patients were more likely to live alone than relatives/friends; (3) requests differed by whether living alone and by type of enquirer, for example, significantly more people living with others requested emotional support than those living alone, and this contrast was most marked for patients than relatives/friends. This study, notwithstanding its limitations, highlights some of the differences in the use of a service and demonstrates the complexity of information and support seeking.
We investigated five single-nucleotide polymorphism (SNP) sites of tumor necrosis factor-alpha (TNF-alpha) promoter, the distribution of five-locus TNF-alpha haplotypes, and extended human leukocyte antigen (HLA)/TNF-alpha haplotypes in 200 parents from 100 unrelated Korean families. TNF-alpha SNPs were typed using polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP) and PCR restriction fragment length polymorphism (PCR-RFLP) methods. The frequencies of -1031C, -863A, -857T, -308A, and -238A alleles were 0.185, 0.145, 0.140, 0.060, and 0.040, respectively. The allele frequencies in Koreans were similar to those of Japanese. A total of five TNF-alpha haplotypes (-1031/-863/-857/-308/-238) were detected in 196 parents: TCCGG (frequency 0.617), CACGG (0.143), TCTGG (0.143), TCCAG (0.061), and CCCGA (0.036). Five most common extended HLA/TNF-alpha haplotypes (frequencies >0.020) accounted for 16% (63/392) of the total haplotypes. A total of 223 HLA haplotypes and 239 HLA/TNF-alpha haplotypes were detected, indicating that most HLA haplotypes are exclusively associated with particular TNF-alpha haplotypes.
