  • Cancer risk following organ transplantation : a nationwide cohort study in Sweden
  • 2003
  • Ingår i: British Journal of Cancer. - 0007-0920 .- 1532-1827. ; 89:7, s. 1221-1227

    • A substantial excess risk of lymphomas and nonmelanoma skin cancer has been demonstrated following organ transplantation. Large sample size and long follow-up time may, however, allow more accurate risk estimates and detailed understanding of long-term cancer risk. The objective of the study was to assess the risk of cancer following organ transplantation. A nationwide cohort study comprising 5931 patients who underwent transplantation of kidney, liver or other organs during 1970-1997 in Sweden was conducted. Complete follow-up was accomplished through linkage to nationwide databases. We used comparisons with the entire Swedish population to calculate standardised incidence ratios (SIRs), and Poisson regression for multivariate internal analyses of relative risks (RRs) with 95% confidence intervals (CI). Overall, we observed 692 incident first cancers vs 171 expected (SIR 4.0; 95% CI 3.7-4.4). We confirmed marked excesses of nonmelanoma skin cancer (SIR 56.2; 95% CI 49.8-63.2), lip cancer (SIR 53.3; 95% CI 38.0-72.5) and of non-Hodgkin's lymphoma (NHL) (SIR 6.0; 95% CI 4.4-8.0). Compared with patients who underwent kidney transplantation, those who received other organs were at substantially higher risk of NHL (RR 8.4; 95% CI 4.3-16). Besides, we found, significantly, about 20-fold excess risk of cancer of the vulva and vagina, 10-fold of anal cancer, and five-fold of oral cavity and kidney cancer, as well as two- to four-fold excesses of cancer in the oesophagus, stomach, large bowel, urinary bladder, lung and thyroid gland. In conclusion, organ transplantation entails a persistent, about four-fold increased overall cancer risk. The complex pattern of excess risk at many sites challenges current understanding of oncogenic infections that might become activated by immunologic alterations.

  • Alcohol intake and risk of non-Hodgkin lymphoma in men and women
  • 2004
  • Ingår i: Cancer Causes and Control. - 0957-5243 .- 1573-7225. ; 15:10, s. 1067-1076
  • Tidskriftsartikel (övrigt vetenskapligt)abstract
    • OBJECTIVE: The effect of alcohol intake on risk of NHL is unclear. We therefore conducted a population-based case-control study to examine the association between alcohol and NHL risk. METHODS: 613 NHL cases and 480 population controls in Sweden reported their average consumption of beer, wine, and liquor 2 years before the study. Unconditional logistic regression was used to estimate the odds ratios (OR) and corresponding 95% confidence intervals (CI) for associations between alcohol intake and NHL risk. RESULTS: Intake of total alcohol, beer, wine, or liquor was not associated with risk of overall NHL. There was no difference in risk of NHL among those who habitually consumed above 19.1 g of ethanol per day, compared to those who consumed on average 0-2.2 g of ethanol per day (OR = 1.2 (95% CI: 0.8, 1.7); Ptrend = 0.29). However, the association was significantly positive among males (OR = 1.8 (95% CI: 1.1, 2.9); Ptrend = 0.06). Total alcohol, beer, wine, or liquor intake was not associated with any major histopathologic subtype of NHL examined, apart from an association between high wine consumption and increased risk of chronic lymphocytic leukemia. CONCLUSIONS: Alcohol does not appear to be a major etiologic factor for overall NHL, nor its common subtypes.

  • Preoperative serum levels of follicle stimulating hormone (FSH) and prognosis in invasive breast cancer
  • 2004
  • Ingår i: European Journal of Surgical Oncology. - 0748-7983 .- 1532-2157. ; 30:5, s. 495-500
  • Tidskriftsartikel (refereegranskat)abstract
    • AIMS: We investigated the association between preoperative serum levels of follicle stimulating hormone (FSH) and the prognosis in women with invasive breast cancer. METHODS: Serum levels of FSH were measured in 182 premenopausal and 581 peri- or postmenopausal women with invasive breast cancer. They were followed for a mean time of 84 months. The study endpoint was death from breast cancer (182 events). Analyses were stratified on menopausal status. RESULTS: None of the estimates showed a statistically significant result. In both pre- and postmenopausal women there was a nominally higher probability of survival with a higher FSH level. Point estimates in multivariate analysis incorporating age, tumour diameter, axillary lymph status, estrogen and progesterone receptor content and year of treatment indicated a stronger association with FSH levels in premenopausal than postmenopausal women (relative hazard 0.63 or 0.85, respectively in the highest compared with the lowest quartile). CONCLUSION: We did not find any statistically significant association between preoperative serum level of FSH and prognosis. Today, FSH is not a clinical target for intervention or a clinically useful prognostic factor and the results of clinical studies up to date can only be used for motivation of further experimental laboratory research.

  • A randomized trial comparing radical prostatectomy with watchful waiting in early prostate cancer
  • 2002
  • Ingår i: New England Journal of Medicine. - 0028-4793 .- 1533-4406. ; 347:11, s. 781-789
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Radical prostatectomy is widely used in the treatment of early prostate cancer. The possible survival benefit of this treatment, however, is unclear. We conducted a randomized trial to address this question. METHODS: From October 1989 through February 1999, 695 men with newly diagnosed prostate cancer in International Union against Cancer clinical stage T1b, T1c, or T2 were randomly assigned to watchful waiting or radical prostatectomy. We achieved complete follow-up through the year 2000 with blinded evaluation of causes of death. The primary end point was death due to prostate cancer, and the secondary end points were overall mortality, metastasis-free survival, and local progression. RESULTS: During a median of 6.2 years of follow-up, 62 men in the watchful-waiting group and 53 in the radical-prostatectomy group died (P=0.31). Death due to prostate cancer occurred in 31 of 348 of those assigned to watchful waiting (8.9 percent) and in 16 of 347 of those assigned to radical prostatectomy (4.6 percent) (relative hazard, 0.50; 95 percent confidence interval, 0.27 to 0.91; P=0.02). Death due to other causes occurred in 31 of 348 men in the watchful-waiting group (8.9 percent) and in 37 of 347 men in the radical-prostatectomy group (10.6 percent). The men assigned to surgery had a lower relative risk of distant metastases than the men assigned to watchful waiting (relative hazard, 0.63; 95 percent confidence interval, 0.41 to 0.96). CONCLUSIONS: In this randomized trial, radical prostatectomy significantly reduced disease-specific mortality, but there was no significant difference between surgery and watchful waiting in terms of overall survival.

  • Pre-operative oestradiol levels - relation to survival in breast cancer
  • 2001
  • Ingår i: European Journal of Surgical Oncology. - 0748-7983 .- 1532-2157. ; 27:2, s. 152-156
  • Tidskriftsartikel (refereegranskat)abstract
    • AIMS: There are clinical observations that operation during the luteal phase of the menstrual cycle (with high oestradiol levels) may positively influence prognosis in breast cancer. However, few studies have information on plasma levels of hormones pre-operatively. METHODS: We studied 774 women treated for breast cancer where plasma levels of oestradiol had been measured 1-2 days pre-operatively. Date and cause of death were ascertained from the files of the Swedish Cancer Register and 5434 person-years were observed. The endpoint was death with breast cancer as the underlying cause (n=41 and n=158 in the pre- and post-menopausal group, respectively). RESULTS: In life-table analyses, only pre-menopausal patients with oestradiol 500 pmol/l and above had a tendency (not statistically significant) for better survival. Multivariate Cox models with oestradiol modelled in continuous form yielded relative hazards (RH) close to unity in all women and in strata according to menopausal status. CONCLUSIONS: When oestradiol was analysed in categorized form, only women with the highest levels had a tendency for improved prognosis (RH around 0.7; not statistically significant). Moreover, this pattern was not apparent for pre-menopausal women. Our findings contradict the notion that the pre-operative oestradiol level is independently associated with breast cancer prognosis.

  • Correlates of heterosexual behavior among 23-87 year olds in Denmark and Sweden, 1992-1998
  • 2000
  • Ingår i: Archives of Sexual Behavior. - 0004-0002 .- 1573-2800. ; 29:1, s. 91-106
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Natural history of early, localized prostate cancer
  • 2004
  • Ingår i: Journal of the American Medical Association (JAMA). - 0098-7484 .- 1538-3598. ; 291:22, s. 2713-2719
  • Tidskriftsartikel (refereegranskat)abstract
    • CONTEXT: Among men with early prostate cancer, the natural history without initial therapy determines the potential for survival benefit following radical local treatment. However, little is known about disease progression and mortality beyond 10 to 15 years of watchful waiting. OBJECTIVE: To examine the long-term natural history of untreated, early stage prostatic cancer. DESIGN: Population-based, cohort study with a mean observation period of 21 years. SETTING: Regionally well-defined catchment area in central Sweden (recruitment March 1977 through February 1984). PATIENTS: A consecutive sample of 223 patients (98% of all eligible) with early-stage (T0-T2 NX M0 classification), initially untreated prostatic cancer. Patients with tumor progression were hormonally treated (either by orchiectomy or estrogens) if they had symptoms. MAIN OUTCOME MEASURES: Progression-free, cause-specific, and overall survival. RESULTS: After complete follow-up, 39 (17%) of all patients experienced generalized disease. Most cancers had an indolent course during the first 10 to 15 years. However, further follow-up from 15 (when 49 patients were still alive) to 20 years revealed a substantial decrease in cumulative progression-free survival (from 45.0% to 36.0%), survival without metastases (from 76.9% to 51.2%), and prostate cancer-specific survival (from 78.7% to 54.4%). The prostate cancer mortality rate increased from 15 per 1000 person-years (95% confidence interval, 10-21) during the first 15 years to 44 per 1000 person-years (95% confidence interval, 22-88) beyond 15 years of follow-up (P =.01). CONCLUSION: Although most prostate cancers diagnosed at an early stage have an indolent course, local tumor progression and aggressive metastatic disease may develop in the long term. These findings would support early radical treatment, notably among patients with an estimated life expectancy exceeding 15 years.
