    • Hepatic tumours are rare in childhood. Within the frame of the EUROCARE II study, a total of 328 liver tumours in patients aged 0--14 years were reported during the period 1978--1989. The childhood cancer registries in UK and Germany contributed approximately a third of the cases each. Hepatoblastoma accounted for 71% of cases. The 5-year survival was 36% 95% confidence interval (CI) 28--46%, with no significant difference between the genders. Patients aged 10--14 years did worse, especially boys. Survival improved significantly during the study period. Survival in hepatocellular carcinoma was lower, 20% (95% CI 6--52%), and showed no improvement during the study period.

  • Perinatal exposure to infection and risk of childhood leukemia
  • 2002
  • Ingår i: Medical and Pediatric Oncology. - 0098-1532. ; 38:6, s. 391-397
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: A population-based case-control study was conducted to investigate the association between childhood leukemia and infectious exposures during pregnancy and early neonatal period.PROCEDURE: Children born and diagnosed with leukemia between 1973 and 1989 in Sweden (578 lymphatic, 74 myeloid) were selected as cases. One control was randomly selected for each case and individually matched by sex, month, and year of birth. Children with Down's syndrome were excluded. Exposure data were blindly abstracted from antenatal, obstetric, and other standardized medical records. Odds ratios (OR) and 95% confidence intervals (CI) were calculated by conditional logistic regression.RESULTS: A history of maternal infection was not significantly associated with childhood leukemia, OR = 1.25 (95% CI 0.95-1.65). Maternal lower genital tract infection significantly increased the risk of childhood leukemia, OR = 1.78 (95% CI 1.17-2.72), and especially for children over 4 years of age at diagnosis, OR = 2.01 (95% CI 1.12-3.80). Neonatal infection was not associated with the risk of leukemia. The results remained unaltered after adjustment for potential confounders, and separate analyses for myeloid and lymphoid leukemia.CONCLUSIONS: We could document an association between exposure to maternal lower genital tract infection in utero, and a subsequent risk for childhood leukemia, which indicate the importance of an early exposure.

  • Severe lung lesions caused by Salmonella are prevented by inhibition of the contact system
  • 2000
  • Ingår i: Journal of Experimental Medicine. - Rockefeller University Press. - 1540-9538. ; 192:10, s. 1415-1424

    • Vascular damage induced by trauma, inflammation, or infection results in an alteration of the endothelium from a nonactivated to a procoagulant, vasoconstrictive, and proinflammatory state, and can lead to life-threatening complications. Here we report that activation of the contact system by Salmonella leads to massive infiltration of red blood cells and fibrin deposition in the lungs of infected rats. These pulmonary lesions were prevented when the infected animals were treated with H-D-Pro-Phe-Arg-chloromethylketone, an inhibitor of coagulation factor XII and plasma kallikrein, suggesting that inhibition of contact system activation could be used therapeutically in severe infectious disease.

  • Human polyomavirus DNA is not detected in Guthrie cards (dried blood spots) from children who developed acute lymphoblastic leukemia
  • 2003
  • Ingår i: Medical and Pediatric Oncology. - 0098-1532. ; 40:4, s. 219-223
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundEpidemiological evidence has suggested that some childhood acute lymphoblastic leukemia (ALL) may be initiated in utero and may have an infectious etiology. The human polyomavirus JC virus (JCV) has been discussed as a candidate virus, but its presence has not been demonstrated in leukemia cells from children with ALL. The aim of this study was, therefore, to investigate if prenatal human polyomavirus infection could still indirectly be correlated to the development of childhood ALL.ProcedureFifty-four Guthrie cards (stored, dried blood spots filter papers, routinely collected from newborns for different screening analyses), collected at 3–5 days of age, from Swedish children who subsequently developed ALL, as well as from 37 healthy controls, were investigated by nested PCR for the presence of human polyomaviruses JCV and BK virus (BKV).ResultsJCV and BKV DNA were not detected in any of the Guthrie cards from ALL patients or from healthy controls, although all tested samples had amplifiable DNA as confirmed by an HLA DQ PCR.ConclusionsJCV or BKV were not found in any of the dried blood spots of children who later developed ALL or in the healthy controls. These findings suggest that it is unlikely that childhood ALL is associated with an in utero infection with JCV or BKV, although it is not possible to exclude an association with an in utero infection that has become latent in the kidneys with very low levels of circulating virus at birth.

  • Retroviral transduction of human CD34+ cells on fibronectin fragment CH-296 is inhibited by high concentrations of vector containing medium
  • 2001
  • Ingår i: Journal of Gene Medicine. - John Wiley & Sons. - 1521-2254. ; 3:3, s. 207-218
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The objective of the present study was to optimize conditions for retroviral transduction of human cord blood (CB) CD34+ cells and to reveal mechanisms which interfere with efficient gene transfer. METHODS: An MSCV based retroviral vector with the gene for enhanced green fluorescent protein (MGIN) produced by GP+envAM12 (amphotropic envelope), PG13 (gibbon ape leukemia virus envelope) or 293GPG (vesicular stomatitis virus envelope) cell lines was used to transduce cord blood CD34+ cells on Retronectin (fibronectin fragment CH-296) in three different ways: either in vector containing medium (VCM), in fresh medium on Retronectin pre-loaded with vector or in VCM on Retronectin pre-loaded with vector. RESULTS: Paradoxically, the transduction efficiency obtained with pre-load of vector onto Retronectin alone was higher than pre-load plus VCM for PG13-MGIN (67.9 +/- 6.0% vs 24.9 +/- 8.0%) and AM12-MGIN (47.5 +/- 5.8% vs 38.7 +/- 2.2%). Further experiments showed that transduction on Retronectin pre-loaded with PG13-MGIN or AM12-MGIN was inhibited by the presence of the same VCM at high concentrations, but not by the presence of a VCM with a different receptor specificity. If no pre-load of vector was performed, the highest transduction efficiencies were seen when VCMs were diluted 1:10 (MOIs of 3). The inhibitory effect of high titer PG13-MGIN VCM was confirmed in more primitive CD34+CD38low cells and in NOD/SCID repopulating cells, and was also seen in experiments with bone marrow CD34+ cells. CONCLUSIONS: Retroviral transduction of CB CD34+ cells on Retronectin is inhibited by high titer PG13 and GP+envAM12 vector containing medium. Efficient gene transfer to human hematopoietic cells can be obtained by preload alone of the vector onto Retronectin. These findings are of importance for the design of transduction protocols for repopulating hematopoietic cells.

  • Accrual rate-limiting factors in a Swedish randomised ductal carcinoma in situ (DCIS) trial - a demographic study
  • 2000
  • Ingår i: European Journal of Cancer. - IFAC & Elsevier Ltd.. - 1879-0852. ; 36:4, s. 483-488
  • Tidskriftsartikel (refereegranskat)abstract
    • In the last two decades the introduction of mammographic screening in the Western world has increased the number of diagnosed ductal carcinomas in situ (DCIS) considerably. In situ carcinoma of the breast is considered a heterogeneous disease, the natural history of which is not well known. Thus, appropriate treatment needs to be established. For this reason, a randomised trial studying the effect of breast conserving operation with or without postoperative radiotherapy was instituted in Southern Sweden in 1987. The aim of the present study was to assess patient accrual, identify limiting factors, and evaluate possible ways to influence these factors in order to increase patient accrual. Between 1987 and 1992, 331 patients had been registered with DCIS in the Regional Tumour Registry, 96 of which had been randomised. All 331 were subjected to chart review studying clinical data, mammography reports, cytology and pathology reports to identify inclusion and exclusion criteria according to the design of the trial. It was found that 5% (18/331) had an incorrect diagnosis of DCIS. According to the trial protocol 52% were not eligible (162/313). Fifty-eight per cent (n=88) of the 151 eligible patients had been correctly randomised. The most common reason for exclusion was lesion size. In 21% (66/313) the lesion was 'too large'. Several other limiting factors were identified such as in cytological and pathological definitions and reports, lack of information/awareness in certain physicians, patient reluctance to participate, which in turn may be influenced by the previous factor. With increased information to participating hospitals and considering the above given facts it should be possible to increase accrual from the 28% noted in the present consecutive demographic study to at least one-third of the diagnosed cases of DCIS.

  • Ipsilateral local recurrence in relation to therapy and morphological characteristics in patients with ductal carcinoma in situ of the breast
  • 2000
  • Ingår i: European Journal of Surgical Oncology. - Elsevier. - 1532-2157. ; 26:5, s. 444-451

    • METHOD AND RESULTS: A standardized histopathological protocol has been designed, in which different histological characteristics of ductal carcinoma in situ (DCIS) are reported: nuclear grade (ng), growth pattern according to Andersen et al., necrosis, size of the lesion, resection margins and focality. Using this protocol a re-evaluation of a population-based consecutive series of 306 cases of DCIS has been done as well as a thorough clinical follow-up. After a median follow-up of 63 months, 13% have developed ipsilateral local recurrences, invasive and/or in situ. Ipsilateral local recurrence-free survival (IL-RFS) was significantly better for patients operated with mastectomy (ME) or breast conserving therapy (BCT) with radiotherapy (RT) than for patients operated with BCT without RT (5-year IL-RFS 96% vs 94% vs 79%, P<0.001). In the subgroup of BCT without RT there were significant differences in IL-RFS between histopathological subgroups: ng 1 + 2 (non-high grade) vs ng 3 (high grade; P=0.014), non-high-grade without comedo-type necrosis vs non-high-grade with comedo-type necrosis vs high-grade (the Van Nuys classification system; P=0.025). Growth pattern (not diffuse vs diffuse) and margins (free vs involved or not evaluated) showed a tendency (P=0.07 and 0.05, respectively) to be associated to IL-RFS. In contrast, no significant differences in IL-RFS were found in subgroups based on mode of detection, focality or size. Ninety-four per cent of the local recurrences after BCT appeared at the previous operation site. CONCLUSIONS: In the BCT without RT group, combinations of either non-high grade and not a diffuse growth pattern or non-high grade and free margins identified groups (constituting approximately 30% of the patients) were at low risk of developing ipsilateral recurrences (6-10%), compared to a 31-37% recurrence risk in the remaining groups during the observed follow-up time. The beneficial effect of post-operative RT for these low-risk groups can be questioned, and should be studied further.
