Photodynamic therapy for the treatment of oral squamous carcinoma - clinical implications resulting from in vitro research.
Photodiagnosis and Photodynamic Therapy 2019 June 19
BACKGROUND: Oral cavity squamous cell carcinoma is a common cancer of the head and neck region. Due to the frequency of diagnoses, high rate of mortality, mutilating nature of classic therapy and numerous complications, new methods of treatment are being sought. One promising solution for treatment which is utilized in many fields of oncology is photodynamic therapy. The purpose of this article is to present a general overview of the use of photodynamic therapy in preclinical in vitro studies.
MATERIALS AND METHODS: A literature search for articles corresponding to the topic of this review was performed using the PubMed and MEDLINE databases using the following keywords: 'oral cavity squamous cell carcinoma,' 'photodynamic therapy,' 'photosensitizer(s),' 'in vitro,' 'cell culture(s),' 'spheroids,' 'CAM model', and 'in vivo.'
RESULTS: Most of the previous work found in the literature search concerns research on the use of various photosensitizers and the determination of their level of phototoxicity against cell lines.
CONCLUDING REMARKS: Research on the photodynamic effect in cell lines may be useful in establishing the mechanisms and effectiveness of the photodynamic method as a starting point for clinical trials. Studies on spheroidal models allows for testing photodynamic therapy under more clinical-like conditions. The Chick Chorioallantoic Membrane Assay provides information about the vascular changes after treatment.
