Background: Acetylsalicylic acid (ASA or aspirin) is one of the world’s most widely used non-steroidal anti-inflammatory drug (NSAID). Numerous studies have shown that the long-term use of aspirin may contribute to longer survival among patients with various types of cancer, including ovarian cancer. Aim: The aim of this study was to investigate the effect of ASA on myeloperoxidase (MPO), which is found at an elevated level in women with ovarian cancer, among others. Methods: The influence of different concentrations of ASA on the chlorinating and peroxidase activity of MPO was analysed. The relationship between the concentration of ASA and the degree of inhibition of MPO activity was determined based on the results. Conclusions: Aspirin has a significant effect on MPO activity. The use of 50 mM ASA resulted in the enzyme activity being inhibited by more than 90%.

The aim of this study is to report the use of ruthenium brachytherapy as an adjunctive treatment in the management of an intraocular extension of the conjunctival squamous cell carcinoma (SCC).In 2013, a 73-year-old man presented with a tumor blocking the angle and infiltrating corneal endothelium. The patient was treated with iridectomy, and after one month, ruthenium brachytherapy was applied. 4.5 years post-irradiation, the treated eye is painless, and no recurrence was noted.We advocate the use of ruthenium brachytherapy as an eye salvage treatment with an intraocular extension of conjunctival SCC.
