- According to recent results, patients with non-melanoma skin cancers are at increased risk of developing non-Hodgkin's lymphoma (NHL). The prognostic significance of this association is unknown. Two cohorts of patients with a first diagnosis of non-melanoma skin cancer and a subsequent diagnosis of either NHL (n = 170) or colon cancer (n = 435) were established using national cancer registry data in Denmark. Two other cohorts of patients in whom NHL (n = 600) or colon cancer (n = 1,541) was the patients' first known malignancy served as comparison groups. Mortality rates were compared using Cox's regression analysis. Among patients younger than 80 years at NHL diagnosis, a history of non-melanoma skin cancer was associated with significantly increased mortality [relative risk (RR) = 1.54; 95% confidence interval: 1.19-1.99]. This association was present in both men (RR = 1.38; 1.02-1.86) and women (RR = 2.15; 1.31-3.54) and was similar after both major subtypes of non-melanoma skin cancer. Overall, antedating non-melanoma skin cancer had no prognostic significance for colon cancer patients (RR = 1.00; 0.84-1.18). Whatever the underlying mechanism, our observation has potential clinical implications. If substantiated in other settings, NHL patients with prior non-melanoma skin cancer may constitute a subgroup of lymphoma patients in need of particular therapeutic attention.

- Correlates of heterosexual behavior, with a particular focus on early and high sexual activity, anal intercourse, prostitute visits, and HIV test activity, were studied. Telephone interviews were conducted with 852 randomly chosen persons who participated as controls in nationwide case-control studies of anogenital cancers in Denmark and Sweden, 1992-1998. While partner numbers and the practice of anal intercourse increased, age at sexual debut declined by 4-5 years (p < 0.001) and the maturation interval between menarche and first coitus halved (from 7 to 3 years, p < 0.001) between persons born in or before 1920 and those born in or after 1960. Women having high sexual activity were more often tested for HIV than less sexually active women, but men visiting prostitutes and those with prior STDs were not HIV tested more than other men. The increasing practice of anal intercourse, particularly among women with many partners, deserves attention, since this practice may erroneously be considered a safe sexual activity. Along with their partners, men with a history of STDs and those visiting prostitutes should be targeted in future safe sex campaigns, since these men appear to be inadequately HIV tested.
