    • Small bowel carcinoid tumor (SBC) is a rare disease of unknown etiology bill with all age-, sex-, and place-specific occurrence that may indicate an occupational origin. A European multicenter population-based case-control study was conducted from 1995 through 1997. Incident SBC cases between 35 and 69 years of age (n = 101) were identified, together with 3335 controls sampled from the catchment area of the cases. Histological review performed by a reference pathologist left 99 cases for study; 84 cases and 2070 population controls were interviewed. The industries most closely associated (a twofold or more odds ratio [OR]) with SBC taking into account a 10-year time lag after exposure were, among women, employment in wholesale industry of food and beverages (OR, 8.2; 95% confidence interval [CI], [1.9 to 34.9]) and among men, manufacture of motor vehicle bodies (OR, 5.2; 95% CI, 1.2 to 22.4), footwear (OR, 3.9: 95% CI, 0.9 to 16.1), and metal structures (OR, 3.3; 95% CI, 1.0 to 10.4). The identified high-risk occupations with all OR above 2 were shoemakers, structural metal preparers, construction painters and other construction workers. bookkeepers, machine fitters, and welders (men). The OR for regular occupational use of organic. solvents for at least half a year was 2.0 (95% CI, 1.0 to 4.2). Exposure to rust-preventive paint containing lead was suggested as another potential occupational exposure (OR, 9.1; 95% CI, 0.8 to 107). This explorative study suggests an association between certain occupational exposures and SBC, bill some of these associations could be attributable to chance. All findings should be regarded as tentative.

  • The importance of smoking and medical history for development of small bowel carcinoid tumor: a European population-based case-control study
  • 2002
  • Ingår i: Cancer Causes and Control. - 1573-7225. ; 13:1, s. 27-34
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: Little is known about the etiology of small bowel carcinoid tumor (SBC), but a few studies have pointed to certain medical and lifestyle factors as potential risk factors. This study aims to evaluate these findings and to identify new associations. Methods: A population-based European multicenter case-control study was conducted from 1995 through 1997. Incident histologically verified 35-69 year-old SBC cases (n = 99) and 3335 controls were recruited; 84 cases and 2070 controls were interviewed. Results: Ever being a smoker was associated with SBC (odds ratio = 1.9; 95% confidence interval 1.1-3.2) and increased risk estimates were seen for all smoking categories. SBC was associated with previous gallstone disease and ovariectomy, but only when these conditions occurred within two years prior to the SBC diagnosis. No association was seen for a history of cholecystitis, liver cirrhosis, ulcerative disease, or Crohn's disease. Intake of alcoholic beverages - as well as medical treatments with radioactive substances, hormones, or corticosteroid tablets - were not associated with SBC. Conclusions: This study indicates that tobacco smoking is a risk factor for SBC. The associations with gallstone and ovarian diseases may be due to enhanced medical surveillance during the early phase of the cancer disease.

  • A 24-Month Study Evaluating the Efficacy and Safety of Denosumab for the Treatment of Men With Low Bone Mineral Density : Results From the ADAMO Trial
  • 2015
  • Ingår i: Journal of Clinical Endocrinology and Metabolism. - : The Endocrine Society. - 0021-972X .- 1945-7197. ; 100:4, s. 1335-1342

    • Context: One in 4 men in the United States aged >50 years will have an osteoporosis-related fracture. Fewer data are available on osteoporosis treatment in men than in women. Objective: The purpose of this study was to evaluate denosumab therapy in men with low bone mineral density (BMD). Design: This was a phase 3 study with 2 treatment periods: a previously reported 12-month double-blind, placebo-controlled phase and a 12-month open-label phase. Setting: This was a multicenter study conducted in North America and Europe. Participants: A total of 228 men entered the open-label phase and 219 completed the study. Intervention: Men from the original denosumab (long-term) and placebo (crossover) groups received 60 mg of denosumab sc every 6 months. Main Outcome Measures: BMD, serum collagen type I C-telopeptide, and safety were measured. Results: During the open-label phase, continued BMD increases occurred with long-term denosumab treatment (2.2% lumbar spine, 0.9% total hip, 1.3% femoral neck, 1.3% trochanter, and 0.2% 1/3 radius), resulting in cumulative 24-month gains from baseline of 8.0%, 3.4%, 3.4%, 4.6%, and 0.7%, respectively (all P < .01). The crossover group showed BMD gains after 12 months of denosumab treatment similar to those of the long-term denosumab group during the first treatment year. Significant reductions in serum collagen type I C-teleopeptide were observed after denosumab administration. Adverse event rates were similar between groups, and no new safety signals were identified. Conclusions: In men with low BMD, denosumab treatment for a second year continued to increase BMD, maintained reductions in bone resorption, and was well tolerated. BMD increased in men initiating denosumab during the second year. These effects were similar to those previously seen in postmenopausal women with osteoporosis and in men with prostate cancer receiving androgen deprivation therapy.

  • Glutathione S-transferase genotype and p53 mutations in adenocarcinoma of the small intestine
  • 2003
  • Ingår i: Scandinavian Journal of Gastroenterology. - : Informa UK Limited. - 1502-7708 .- 0036-5521. ; 38:8, s. 845-849

    • Adenocarcinoma of the small intestine (ASI) is a rare disease of unknown aetiology. The glutathione S-transferase M1 (GSTM1) enzyme catalyses the detoxification of compounds involved in carcinogenesis of adenocarcinoma of the stomach, colon and lung, including constituents of tobacco smoke. We investigated a possible interaction between the lack of GSTM1 enzyme activity and the carcinogenic compounds of tobacco smoke. Based on the theory that certain carcinogens cause specific point mutations in the p53 gene we analysed by single strand conformation polymorphism (SSCP) and sequencing, p53 exon 5-8 of 52 samples of ASI collected in Sweden, Germany, France, Italy and Denmark between 1995 and 1997. The GSTM1 gene status was investigated by multiplex PCR. The prevalence of GSTM1 negative genotype among cases with ASI was 69% and higher than previous reports of 50% suggesting a higher risk of ASI among GSTM1 negative compared with GSTM1 positive subjects. A 'case-only' approach was used to address the combined association between the GSTM1 negative genotype and lifestyle exposures in patients with ASI. Using this method, heavy smokers (>20 pack-years) with the GSTM1 negative genotype had an odds ratio of 4.8; 95% confidence interval (CI) (0.6-38.7) for ASI as compared to smokers who expressed GSTM1. No similar association between alcohol consumption and ASI was found. No p53 mutations in exon 5-8 were found in these samples, but the method may not be sensitive enough to identify smaller differences. Thus p53 does not seem to be the target of carcinogens acting in the small intestine.
