Mean recurrence-free survival of mTHPC—PDT-treated tumors illuminated with 100 mW cm⁻² and 30 J cm⁻² reproduced from Fig. 3 of Cramers et al. (see Ref. 4) and Fig. 2(A) of Triesscheijn et al. (see Ref. 5). The recurrence-free interval is defined by the time taken for a tumor diameter to increase 2 mm from its treatment size. Tumors that had not regrown within 120 days were defined as cured.
