Abstract

In last few years, adjuvant post-operative radiotherapy and occasionally preoperative irradiation combined with chemotherapy are considered as effective practices to improve disease control and survival in gastric cancer. Yet, chemoradiotherapy result in severe toxicities and radiotherapy practice is a significant contributor. For a recommended median dose of 45 Gy to the treatment volume of stomach and surrounding lymphnode regions, considerable doses are likely to be delivered to liver, kidneys and spinal cord. Few literatures and texts state about the radiotherapy techniques, with recent emphasis on conformal (3-D CRT) or intensity-modulated radiotherapy (IMRT). However, these facilities are not uniformly available in most developing countries where stomach cancer is common. This is a report on practical aspects of radiotherapy techniques and planning which can be utilised as per available settings of a radiotherapy department.
