|Titolo:||Glucose-6-phosphate dehydrogenase deficiency and cancer in a Sardinian male population: a case-control study|
|Data di pubblicazione:||1989|
|Abstract:||A case-control study was conducted to test the hypothesis whether the genetic condition of glucose-6-phosphate dehydrogenase (G6PD) deficiency is associated with a reduced risk of cancer. One hundred and eighty seven male cancer patients admitted to hospitals in Cagliari (Sardinia, Italy), between November 1984 and March 1986, were compared with 186 male patients with other diseases, except hemolytic anemia, admitted to the same hospitals in the same period. In contrast to previous reports, our study found no reduction of cancer risk in G6PD-deficient subjects. The study had sufficient statistical power to detect a 0.5-fold decrease in the risk of cancer. The recent suggestion from other studies that tumoral cells of G6PD-deficient subjects can produce their own G6PD, seems to be consistent with this negative finding. Among those subjects presenting some level of erythrocyte G6PD activity, the average enzyme activity was significantly higher in cancer patients than in controls. This finding is consistent with previous experimental studies suggesting a positive correlation between cell proliferation and G6PD activity.|
