Colorectal cancer is one of the most common cancers diagnosed in the United States. In Arizona, nearly 3,000 new cases of colorectal cancer are diagnosed, and more than 1,000 state residents die from the disease each year. At the Gastrointestinal (GI) Cancer Center at City of Hope® Cancer Center Phoenix, our clinicians are committed to offering state-of-the-art screening and diagnostic tools to help detect colorectal or other types of gastrointestinal cancer early, along with innovative treatments options for patients at every stage of disease.

Our GI Cancer Center treats all gastrointestinal-related cancers, including:

Our gastroenterologists also work with each patient’s care team to address gastrointestinal symptoms or side effects that may be caused by the disease or its treatments, no matter which GI cancer type they have.
 

GI Cancer Care in Phoenix

The gastroenterologists and oncologists at the GI Cancer Center at City of Hope Phoenix offer patients a variety surgical, non-surgical and minimally invasive techniques to diagnose and treat tumors and help reduce symptoms and side effects. 

Treatments and diagnostic tools for most gastrointestinal diseases include the following, either alone or in combination:

  • Chemotherapy
  • Genetic testing
  • Genomic testing
  • Immunotherapy
  • Radiation therapy
  • Surgery
  • Targeted therapy

The doctors at the GI Cancer Center at City of Hope Phoenix are on the leading edge of new technologies and treatments and offer a variety of GI cancer screening and care options, including: 

  • Colonoscopy to examine the inner lining of the colon and rectum, find and remove polyps or pre-cancerous growths and find blockages
  • Endoscopic mucosal resection to remove abnormal tissue
  • Hyperthermic intraperitoneal chemotherapy (HIPEC), which delivers highly concentrated, heated chemotherapy directly to the abdominal cavity
  • Endoscopic ultrasound with fine needle biopsy, which combines an endoscope and an ultrasound to take detailed pictures of the digestive system and collect biopsy tissue if necessary
  • Radiofrequency ablation that uses heat to destroy cancerous tissue and shrink tumors

Detecting Cancer with GI Genius

The gastroenterologists at the GI Cancer Center at City of Hope Phoenix, employ an advanced diagnostic tool called GI Genius™, which uses artificial intelligence (AI) technology to help doctors more clearly identify colon polyps, cancerous or pre-cancerous lesions or adenomas. GI Genius highlights suspicious areas of the colon and rectum, prompting doctors to take a closer look.

GI Genius is the first AI device approved by the U.S. Food and Drug Administration for use during a colonoscopy, and the doctors at the GI Cancer Center at City of Hope Phoenix were the first in the Western United States to use it.
