Our Doctors

Care and Treatment of Gastrointestinal Cancers

Treatment Options

The Stanford Gastrointestinal (GI) Cancer Program offers extensive treatment expertise to patients with all forms of gastrointestinal (GI) cancers. Specialists from a broad range of disciplines participate in a multi-specialty approach to the care of patients. The Stanford Cancer Center's GI Cancer Tumor Board and multi-specialty Liver Tumor Board provide a thorough and collaborative plan for each patient.

GI Cancer Program doctors are leaders in their subspecialty fields and have access to the most advanced technologies and therapies available, including:

3-D conformal radiation therapy

A radiology technique where the beams of radiation used in treatment are shaped to match the tumor and uses targeting information to focus precisely on the tumor.

Intensity modulated radiation therapy

An advanced type of radiation technology that manipulates beams of radiation to conform to the shape of a tumor.

Stereoactive ablative body radiotherapy (SABR)

A treatment using sophisticated computerized imaging to precisely target a narrow X-ray beam.

Targeted therapies

Targeted therapies can target cancerous cells without affecting healthy tissue, unlike radiation and chemotherapy treatments.

Virtual endoscopy

Virtual endoscopy (including virtual colonoscopy and virtual bronchoscopy) allows doctors to explore internal structures in non-invasive ways using advanced imaging technology and computer algorithms.

Clinical Trials

Current research

The Stanford team is currently conducting trials of targeted agents in gastroesophageal, colorectal, pancreatic, GIST, and neuroendocrine tumors.

For patients with early stage pancreatic cancer, a Phase III trial is testing a novel vaccine in combination with standard chemotherapy or chemoradiation.

Recent GI cancer research breakthroughs

Stanford doctors conducted several of the key trials that led to the widespread use of targeted therapies for GI cancers, including angiogenesis inhibitors for colorectal, neuroendocrine, and hepatocellular cancer and epidermal growth factor receptor (EGFR) inhibitors that are now routinely used in colorectal cancers.

Clinical trials

The Stanford Gastrointestinal (GI) Cancer Program always has new clinical trials beginning. Before beginning treatment, ask your doctor about any clinical trials you should consider. Learn more about clinical trials for cancer patients.

Clinical trial eligibility flowcharts

Eligibility flowcharts map clinical trials to specific types of cancers to determine if a participant is eligible for the particular clinical trial. View all gastrointestinal cancer eligibility flowcharts at the Stanford Cancer Institute.
