During photodynamic therapy (PDT) it is important to monitor the treatment progress to achieve the intended therapeutic outcome. Chemiluminescence (CL) provides a sensitive and selective means for (1)O(2) detection. In our study, by comparing CL with the corresponding in situ PDT treatment protocols and the treatment effect, the results indicate that the treatment outcome for tumors was governed by a set of dosimetry factors with a rather complicated relationship, but there was a remarkable connection between tumor treatment effect and CL. In conclusion, CL can be used in in vivo PDT to determine the dose of tumor treatment and monitor the treatment threshold. By monitoring CL it is feasible to determine PDT dose to predict tumor treatment effect.
