Hypothesis
Do malignant cells differ intrinsically from their normal counterparts in respect of sensitivity to damage by hyperthermia?
Conclusion
CFU-GM from normal blood are less sensitive to heat than those from normal marrow or patients with chronic granulocytic leukaemia.
Supporting Evidence
- CFU-GM from normal blood were consistently less sensitive to damage by heat than normal marrow CFU-GM.
- There was no significant difference between the heat sensitivities of CFU-GM derived from marrow from normal individuals and patients with CGL.
- The data provide no support for the hypothesis that malignant cells differ intrinsically from their normal counterparts in respect of sensitivity to damage by hyperthermia.
Takeaway
This study looked at how heat affects blood and marrow cells in cancer patients. It found that normal blood cells are tougher against heat than those from the marrow.
Methodology
Cells were heated at temperatures between 41.5°C and 44.0°C and then cultured to assess their survival.
Limitations
Not all criteria for a fair comparison were satisfied, particularly regarding cell kinetic status.
Participant Demographics
Equal numbers of male and female normal volunteers and chronic granulocytic leukaemia patients.
