Lymphocyte transformation in patients with Kaposi's sarcoma

This study describes a correlation between the morphologic types of cutaneous Kaposi's sarcomata and the capacity of lymphocytes to be stimulated in culture with PHA and tumour cells. Lymphocytes from patients with the sarcoma and from normal controls were cultured in vitro with PHA, autologous...

description This study describes a correlation between the morphologic types of cutaneous Kaposi's sarcomata and the capacity of lymphocytes to be stimulated in culture with PHA and tumour cells. Lymphocytes from patients with the sarcoma and from normal controls were cultured in vitro with PHA, autologous Mitomycin‐inhibited tumour cells, and control cells. Lymphocyte transformation was evaluated by measuring the uptake of 125 iodo‐2′ deoxyuridine. Lymphocytes from seven of 21 Kaposi patients showed increased transformation in cultures containing tumour cells and six of these seven patients had nodular or infiltrative disease. An impaired response to both PHA and tumour cells was noted in patients with florid tumours, a form thought to be associated with a diminished host response. Standardized extracts of tumour and control cells were incubated with homologous lymphocytes from other Kaposi patients and normal controls. Two of nine cultures from Kaposi patients showed increased isotope uptake, compared with none of three control cultures. La présente étude met en évidence une corrélation entre les types morphologiques du sarcome cutané de Kaposi et l'aptitude des lymphocytes à se transformer dans des cultures contenant de la PHA et des cellules tumorales. Des lymphocytes de malades atteints de sarcome et de témoins normaux ont été cultivés in vitro avec de la PHA, des cellules‐témoins et des cellules tumorales autologues inhibées par la Mitomycine. La transformation des lymphocytes a été évaluée d'après l'incorporation de 125 iodo‐2' désoxy‐uridine. On a constaté une transformation accrue des lymphocytes de 7 malades sur 21 dans les cultures contenant des cellules tumorales, dont 6 provenaient de sujets atteints d'une forme de tumeur nodulaire ou infiltrante. On a observé une réponse atténuée à la PHA et aux cellules tumorales chez les malades atteints de tumeurs florides, forme que l'on croit associée à une réponse atténuée de l'hǒte. Des extraits normalisés de cellules tumorales et de cellules‐témoins ont été incubés avec des lymphocytes homologues provenant d'autres sujets atteints de sarcome de Kaposi et de témoins normaux. On a observé une incorporation accrue d'isotopes dans 2 des 9 cultures provenant des malades, ce qui ne s'est produit dans aucune des 3 cultures‐témoins.
