COMBINING HIGH ENERGY PHOTONS WITH DOXORUBICIN AND CYCLOPHOSPHAMIDE DRUGS TO REDUCE RADIATION THERAPY SESSIONS FOR BREAST CANCER PATIENTS

Radiotherapy and chemotherapy are methods for breast cancer treatment.Chemotherapy involves giving the patient a toxic drug that works to stop cancer cell growth or prevents the spread of the tumor.Radiotherapy involves using high energy photons produced from a radioactive source or linear accelerator.Because the limited tolerance of human organs to radiation appears to be a need to enhance radiotherapy by increasing the absorbed dose inside human target.One of those methods to enhance radiotherapy is to enhance cross section of tumor by adding a contrast agent into tumor during radiotherapy session.Since breast cancer second ranks follows lung cancer in the world so that the research deals with breast cancer radiotherapy sessions.The research is based on two variables, first adding Doxorubicin and Cyclophosphamide as chemo-drugs during radiotherapy sessions.Second increase the energy that is used in radiotherapy sessions.By using a simulation program to apply radiotherapy session with chemo-drug the research found out there is an enhancement in the radiotherapy session represented by a reduction from 30 sessions (60 Gy) to 13 sessions (26 Gy) or 15 sessions (30 Gy) depending on the energy of photon beam that is used in the radiotherapy sessions.This, in turn, provides a speedy recovery for breast cancer patients with the least possible exposure to ionizing radiation and a shortened exposure time, meaning the fewest possible side effects for patients exposed to radiation.
