Abstract
Abstract Photodynamic therapy (PDT) is an anticancer treatment modality that is poorly adopted into clinical practice for a variety of factors. Though fundamental studies supporting its utility abound, few clinical trials are performed on its use. This may be due to failures in the translation of treatment protocols used in fundamental studies into clinically viable protocols. This study seeks to develop a clinically viable protocol for the treatment of colorectal cancer using nanoparticle‐based PDT by using three complementary animal models. Using the porphysome nanoparticle as a model photosensitizer, several theoretical and practical challenges to the clinical delivery of PDT are addressed including the required drug‐light interval (DLI), the route of administration, and the method of light irradiation delivery. This study finds that nanoparticle‐based PDT can effectively ablate colorectal cancer tumors, that PDT can be effectively delivered after a relatively short DLI, and that safety concerns related to off‐target effects can be mitigated through the peritumoral administration of the photosensitizer and the transanal intraluminal placement of light irradiation. These findings lay the framework for future clinical trials investigating the use of PDT as a component of the multi‐modal approach to the treatment of colorectal cancer.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
