Effect of radiotherapy on phagocytosis percentage and index in patients with oral squamous cell carcinoma.

Background: Phagocytosis plays an important role in the fundamental process of immunity and maintains systemic tissue homeostasis. Phagocytosis function is assessed in radiotherapy to signify the prognosis of patient. Therefore, we designed a study to assess and compare the phagocytosis percentage and phagocytic index of the leucocytes in patients with oral cancer before and after radiotherapy.
