Pentoxyphyllin AND Radiotherapy

Scleroderma is the general disease of the connective tissue, which can be characterized by the proliferation of the connective tissue and fibrosis. According to the results of international studies scleroderma is frequently accompanied by neoplastic diseases, among which the most often occurring is the neoplastic pathology of the breast and the lungs. In May 2007, in the case of our 40-year-old woman patient the histological examination of the tumor we noticed in the left breast verified invasive carcinoma...

Aim in cancer therapy is to increase the therapeutic ratio eliminating the disease while minimizing toxicity to normal tissues. Radiation therapy is a main component in targeting cancer. Radiosensitizing agents like pentoxyphylline (PTX) have been evaluated to improve radiotherapy. Commonly, cells respond to radiation by the activation of specific early and late response genes as well as by inhibition of genes, which are expressed under normal conditions. A display of the genetic distinctions at the level of transcription is given here to characterize the molecular events underlying the radiosensitizing mechanisms...
