To evaluate the efficacy of dihematoporphyrin ether (PHOTOFRIN)‐mediated photodynamic therapy (PDT) for the treatment of diffuse field cancerization and Tis‐T2N0M0 squamous cell carcinoma (SqCCA) of the oral cavity and oropharynx in patients not amenable to or that have failed conventional head and neck cancer treatment. 

Photodynamic therapy: the imminent milieu for treating oral lesions.

Oral infections (such as mucosal and endodontic infections, periodontal diseases, caries, and peri-implantitis) are among the specific targets where PDT can be applied, and efficacy depends on the local dose deposited in the lesion as well as oxygen availability in theLesion.

A light-based therapy namely Photodynamic therapy (PDT) is presented that showed promise, specifically excellent mucosal healing, in treatment of oral cancers and other malignancies and is presented as a low-cost modality.

Photodynamic therapy in the upper aerodigestive tract. Overview and outlook

A contemporary and comprehensive review on the role of photodynamic therapy in the treatment of (pre)malignancies of the UADT is presented and further clinical studies are needed to better define its true value in head and neck oncology.

A current perspective is offered from a fairly selective PDT program that has achieved dramatic lasting responses and where PDT may fit in the treatment spectrum for head and neck cancers is one of the unanswered questions requiring further study.

Oral Cavity: Early Lesions

Possible sensitizers are discussed that can be employed to treat early squamous cell carcinomas of the oral cavity that can provide the possibility of reducing side effects.

Targeted photodynamic therapy in head and neck squamous cell carcinoma: heading into the future

An insight into the future of photodynamic therapy (PDT) in head and neck squamous cell carcinoma (HNSCC) is given through the combination of a photosensitizing agent with light and oxygen, leading to selective tumor eradication.

Photodynamic therapy for squamous cell carcinoma of the head and neck: narrative review focusing on photosensitizers

It is suggested that PDT is a promising treatment modality for early-stage SCCHN, and the low level of evidence of the included studies could help to design robust clinical trials to determine the efficacy of PDT inSCCHN.

It is concluded that PDT is as effective as primary surgical resection for the treatment of early-stage SCC of the oral cavity and that it is a valid function-preserving approach to treatment.

The current use of first- and second-generation photosensitisers in oncology is reviewed, especially absorption of longer wavelength light which penetrates deeper into tissue and faster clearance from normal tissue.

Prognostic factors in the recurrence of stage I and II squamous cell cancer of the oral cavity.

It is revealed that when various interactions between variables were controlled for, only the presence of a positive surgical margin or a tumor depth greater than 5 mm was significantly associated with recurrence, and each individually increased the likelihood of recurrence almost threefold.
