  • Smoking and the risk of leukemia, lymphoma, and multiple myeloma (Sweden)

    • While several epidemiologic studies have indicated a link between smoking and the risk of developing hematolymphoproliferative cancers (chiefly leukemias, lymphomas, and multiple myelomas), in particular myeloid leukemia, the role of tobacco in the etiology of these neoplasms remains unclear. To evaluate the potential impact of tobacco use on development of leukemia, lymphoma, and multiple myeloma, we conducted a cohort study of 334,957 Swedish construction workers using prospectively collected exposure-information with complete long-term follow-up. A total of 1,322 incident neoplasms occurred during the study period, 1971-91. We found no significant association between smoking status, number of cigarettes smoked, or duration of smoking and the risk of developing leukemias, lymphomas, or multiple myeloma. There was a suggestion of a positive association between smoking and the risk of developing Hodgkin's disease, although the rate ratios were not significantly elevated, except for young current smokers. No positive dose-risk trends emerged. Our study provides no evidence that smoking bears any major relationship to the occurrence of leukemias, non-Hodgkin's lymphomas, or multiple myeloma.

  • Benign anal lesions, inflammatory bowel disease and risk for high-riskive and -negative anal carcinoma
  • 1998
  • Ingår i: British Journal of Cancer. - 0007-0920 .- 1532-1827. ; 78:11, s. 1534-1538

    • A central role in anal carcinogenesis of high-risk types of human papillomaviruses (hrHPV) was recently established, but the possible role of benign anal lesions has not been addressed in hrHPV-positive and -negative anal cancers. As part of a population-based case-control study in Denmark and Sweden, we interviewed 417 case patients (93 men and 324 women) diagnosed during the period 1991-94 with invasive or in situ anal cancer, 534 patients with adenocarcinoma of the rectum and 554 population controls. Anal cancer specimens (n = 388) were tested for HPV by the polymerase chain reaction. Excluding the 5 years immediately before diagnosis, men, but not women, with anal cancer reported a history of haemorrhoids [multivariate odds ratio (OR) 1.8; 95% confidence interval (CI) 1.04-3.2] and unspecific anal irritation (OR 4.5; CI 2.3-8.7) significantly more often than controls. Women with anal cancer did not report a history of benign anal lesions other than anal abscess to any greater extent than controls, but they had used anal suppositories more often (OR 1.5; CI 1.1-2.0). Patients with hrHPV in anal cancer tissue (84%) and those without (16%) reported similar histories of most benign anal lesions, but anal fissure or fistula was more common among hrHPV-positive cases. Ulcerative colitis and Crohn's disease, reported by <1% of study participants, were not associated with anal cancer risk. The higher proportion of hrHPV-positive anal cancers among case patients with anal fissure or fistula suggests that such mucosal lesions may provide direct viral access to basal epithelial layers. Since risk associations with benign anal lesions in men may be confounded by unreported sexual behaviour, and since risk associations in women were generally negative, it seems unlikely that benign anal lesions act as promoters in hrHPV-associated anal carcinogenesis. Moreover, benign anal lesions appear not to be linked to an alternative, hrHPV-unassociated causal pathway to anal cancer. Ulcerative colitis and Crohn's disease were not supported as causal factors for anal cancer.

  • [Sexually transmitted infection as a cause of anal cancer]
  • 1998
  • Ingår i: Ugeskrift for læger. - 0041-5782 .- 1603-6824. ; 160:49, s. 7109-7117
  • Tidskriftsartikel (refereegranskat)abstract
    • Interviews were carried out with 423 women and 93 men with invasive or in situ anal cancer in Denmark and Sweden in a search for clues to the aetiology of this neoplasm. Patients with rectal adenocarcinoma (n = 534) and persons drawn from the background population (n = 554) served as controls. Multivariate logistic regression analyses confirmed previous observations of a strong association between either male homosexual experience or a history of anogenital warts and the risk for anal cancer. Moreover, hitherto unknown, but strong and consistent associations were observed between measures of high heterosexual activity and the risk for anal cancer among both sexes. Polymerase chain reaction analysis revealed human papilloma-virus DNA in the majority (88%) of anal cancer specimens but in none of 20 examined rectal adenocarcinomas. It is concluded that most anal cancers appear to be caused by sexually transmitted types of human papillomaviruses and, consequently, that anal cancer is a potentially preventable neoplasm.

  • Childbearing and the risk of Hodgkin's disease
  • 1998
  • Ingår i: Cancer Epidemiology, Biomarkers and Prevention. - 1055-9965 .- 1538-7755. ; 7:9, s. 831-834

    • The causes of Hodgkin's disease remain incompletely known, but a higher incidence in men than in women has prompted an interest in the role of female sex hormones and reproductive history. Available epidemiological data are, however, contradictory. We analyzed possible associations between parity, age at first birth, and the risk of developing Hodgkin's disease by a linkage between the Swedish Cancer Register and a nationwide Fertility Register. Among women born between 1925 and 1972, 917 cases with Hodgkin's disease and concomitant fertility information were identified. For each case patient, five age-matched controls were randomly selected among women in the Fertility Register. Conditional logistic regression was used to estimate odds ratios of Hodgkin's disease associated with a birth. We found a slightly and nonsignificantly reduced risk of Hodgkin's disease in ever-parous compared with nulliparous women. Among parous women, the number of children was unrelated to risk, whereas there was some evidence of an increased risk with late age at first birth in women under age 45 at diagnosis. No clear temporal relations between childbearing and subsequent risk were discernible in any parity or age group. Although uncontrolled confounding might have affected our results, they do not indicate that hormonal or immunological changes associated with childbearing play a role in the development of Hodgkin's disease.

  • Reactions to gastrointestinal cancer : variation in mental adjustment and emotional well-being over time in patients with different prognoses
  • 1998
  • Ingår i: Psycho-Oncology. - 1057-9249 .- 1099-1611. ; 7:5, s. 413-423
  • Tidskriftsartikel (refereegranskat)abstract
    • The relation between mental adjustment, often referred to as coping strategies, and emotional well-being and their changes over time were studied in 139 consecutive, newly diagnosed gastrointestinal cancer patients. Sixty-six patients were potentially cured since all known disease could be removed by surgery, whereas in 73 patients, this was not possible. A more confronting reaction to the diagnosis was associated with better emotional well-being whereas avoidance of reminders of, and intrusive thoughts about the disease were associated with more distress. In agreement with other studies, we found that the coping strategy 'Fighting Spirit' was associated with better emotional well-being while the reverse was true for the strategies 'Hopeless/Helplessness' and 'Anxious Preoccupation'. There were only minor changes over time in the average values of emotional well-being and coping strategies, particularly among patients who at diagnosis were considered incurable. In analyses of each individual's changes of predominant coping style and whether they were categorized as cases/doubtful cases on the HAD anxiety and depression scale, marked changes were, however, seen in several patients. The analyses of mean values give an impression of stability, whereas analyses of the number of patients with a specific predominant coping strategy and how they change, give another. The question of whether coping strategies and emotional well-being change through the course of the disease has no simple and obvious answer. Whether some of the investigated coping strategies should be conceptualized in terms of coping, or whether they are an outcome of the coping efforts, are discussed.
