From: Foscan® uptake and tissue distribution in relation to photodynamic efficacy
Mean recurrence-free survival for groups of mice illuminated at various times after a single Foscan dose (•) or two drug doses separated by 72 h (○). Results are expressed as a function of mean tumour drug levels (A), or mean plasma levels (B), measured in separate groups of mice, for each drug–light interval (written beside the data points).
