	P (wt%)	S (wt%)	Zn (wt%)	Pt (wt%)
Untreated	2.46 ± 1.04	5.03 ± 0.73	0.025 ± 0.022	<DL
Hyperthermic	2.91 ± 1.08	6.48 ± 1.25	0.045 ± 0.015	0.016 ± 0.002
Normothermic	2.21 ± 0.61	4.68 ± 1.10	0.036 ± 0.014	0.018 ± 0.007

The data set comprised 2 untreated, 5 hyperthermic and 7 normothemic treated tumor samples, examined at 75 μm from the peritoneal membrane.
