Article Synopsis
  • Photodynamic therapy (PDT) effectively targets and destroys cells associated with human papillomavirus (HPV), with a high rate of complete regression observed in both low- and high-squamous intraepithelial lesions among 143 patients studied.* -
  • The study demonstrated significant changes in patients' inflammatory responses post-treatment, including increased white blood cell counts and elevated body temperatures, indicating an immune response triggered by the therapy.* -
  • Acute inflammation resulting from PDT may enhance its antiviral and antitumor effects by activating the immune system and causing changes in local blood flow in the treated areas.*

We present the findings of assessing the expression levels of extracellular TLR2 and TLR4 and intracellular TLR3 and TLR8 correlating with the severity of clinical manifestations of HPV infection. A total of 199 women took part in a single-center prospective comparative research study on TLR2, TLR3, TLR4 and TLR8 expression in HPV-related cervical lesions. TLRs' mRNA expression was analyzed using real-time reverse transcription polymerase chain reaction (RT-PCR).

This article presents two cases of non-melanoma skin cancer treated with photodynamic therapy (PDT). The first case involved a 74-year-old woman with a 4 cm basal cell carcinoma on her right zygomatic region, while the second case involved a 83-year-old woman with a 6 cm squamous cell carcinoma on her left peri‑auricular area. Both patients underwent two sessions of systemic PDT, with chlorin E6 (Photoran) as the photosensitizer, followed by red light illumination.
