  • Induction and quantification of hepatic metastases from a human colonic cancer in the nude rat

    • Nude rats were injected with human colonic cancer cells (LS 174 T) in the superior mesenteric vein and the extent of hepatic metastases at sacrifice was estimated by visual inspection and computer-based area calculation. After 3 weeks, 5.0 x 10(6) cells caused hepatic metastases in 14/14 rats whereas 0.5 x 10(6) cells failed to produce liver metastases in 4/4 rats (P < 0.001). Injection of 1.0 x 10(7) cells caused portal vein occlusion in 3/5 rats. Extrahepatic tumour growth was rare; lung metastases were observed in four rats, and three rats had local tumour in the abdomen. The average extent of hepatic tumour replacement was 20.2 +/- 4.0%. Injection of embolies or single cells did not affect the incidence or extent of hepatic metastases. The incidence of hepatic metastases was similar in male and female rats, but the extent of hepatic tumour was larger in males (24.6%) than in females (3.2%) (P = 0.005). The pathophysiological similarities to human disease should make this model suitable for diagnostic and therapeutic studies with clinical application.

  • Coping, psychosocial well-being and anxiety in cancer patients at follow-up visits
  • 1994
  • Ingår i: Acta Oncologica. - : Informa UK Limited. - 0284-186X .- 1651-226X. ; 33:8, s. 887-894
  • Tidskriftsartikel (refereegranskat)abstract
    • Coping, psychosocial well-being, situation-specific anxiety and cancer-related worry were assessed in 197 consecutive cancer patients attending follow-up visits. Participants completed questionnaire on three occasions: at the follow-up visit, some days later (n = 175) and three weeks later (n = 125). High levels of coping styles 'Anxious Preoccupation' and 'Helplessness/Hopelessness' were associated with low levels of psychosocial well-being, more situation-specific anxiety and more cancer-related worry. High levels of 'Fighting Spirit' and 'Fatalistic' were found to be associated with high psychosocial well-being and, for 'Fighting Spirit', also with less cancer-related worry. Patients with a 'dismal' prognosis were found to have higher levels of 'Helplessness/Hopelessness' than patients with a more 'favorable' prognosis. Clinical implications of these findings are discussed.

  • Contrast-enhanced CT scanning in vivo for the quantification of hepatic metastases from a human colonic cancer in the nude rat
  • 1992
  • Ingår i: European Journal of Surgical Oncology. - 0748-7983 .- 1532-2157. ; 18:6, s. 615-623
  • Tidskriftsartikel (refereegranskat)abstract
    • Hepatic metastases were induced in nude rats by intraportal injection of 2.5-5.0 x 10(6) cells from the human colonic cancer cell line LS 174 T. Quantification of tumour burden, expressed as relative metastatic area, was performed by contrast-enhanced computed tomography (CT) scanning in vivo (n = 14), contrast enhanced CT scanning post mortem (n = 21) and computer-based area calculation (CBAC) (n = 21). To determine the false-positive contribution to the estimated tumour burden by the evaluation procedures themselves, six rats without metastases were assessed. The quantification in the three different assessment groups was in close accordance in animals with an intermediate or extensive metastatic burden, but not in rats with a minor (< 4%) tumour burden. The results indicate that contrast-enhanced CT scanning can be used in this model to quantify hepatic metastases, except in animals with few and small lesions. Furthermore, the results suggest a potential for the assessment of therapeutic response by repeated contrast-enhanced CT scanning in vivo, as well as prospects for a corresponding evaluation in man.

  • Radioimmunolocalization of hepatic metastases and subcutaneous xenografts from a human colonic cancer in the nude rat : Aspects of tumour implantation site and mode of antibody administration
  • 1993
  • Ingår i: Acta Oncologica. - 0284-186X .- 1651-226X. ; 32:7-8, s. 877-885
  • Tidskriftsartikel (refereegranskat)abstract
    • Antibody localization was analyzed following intraperitoneal (i.p.) or intravenous (i.v.) injection of the 125I-labelled anti-CEA-MAb I-38S1 in 44 nude rats, in order to evaluate the influence of tumour implantation site and the route of MAb administration. The animals were xenografted with a human colonic cancer (LS 174 T), either in the form of hepatic metastases, subcutaneous (s.c.) tumours or both. Tissue measurements, 4 days after MAb injection, showed better uptake for hepatic than for s.c. tumours, irrespective of the route of antibody administration. Antibody accumulation per g liver metastases was not size dependent for noduli weighing between 4 and 1,110 mg. MAb excretion evaluated in 20 animals and blood activity studied in 11 rats were equivalent 24-96 h following i.p. and i.v. injection. Dissimilar autoradiographic patterns were seen in hepatic metastases with predominantly peripherally located clusters following i.p. and more homogeneously distributed grains after i.v. MAb administration. The results indicate that tumour implantation site has a quantitative, and the route of administration at least a qualitative impact on the tumour accretion of anti-CEA MAb I-38S1 in the present xenograft model.
