Gastro-intestinal (GI) cancers are cancers that affect the digestive system, including the esophagus, stomach, liver, pancreas, small intestine, colon, and rectum. These cancers can significantly impact digestion, nutrition, and overall health. Early detection and timely treatment are essential for improving survival and quality of life.
Radiation therapy plays a crucial role in the management of several GI cancers. It may be used before surgery to shrink tumors, after surgery to reduce recurrence risk, or in combination with chemotherapy for locally advanced disease. In advanced stages, radiation can also help relieve symptoms such as pain, bleeding, or obstruction.
Comprehensive evaluation includes endoscopy, biopsy, and advanced imaging such as CT scan, MRI, or PET-CT to determine the stage and extent of the disease. Treatment planning is individualized based on tumor type, stage, and overall health status.
Modern radiation techniques such as IMRT and IGRT allow precise targeting of the tumor while minimizing exposure to nearby organs like the liver, kidneys, and spinal cord. Combined modality treatment involving surgery, chemotherapy, and radiation therapy often provides the best outcomes.
With a multidisciplinary approach and advanced treatment strategies, many gastro-intestinal cancers can be effectively managed, improving both survival rates and overall quality of life.
