Gastroenterology

The Gastroenterology Department at Cancer Treatment Centers of America® (CTCA), Tulsa, provides extensive expertise in the diagnosis and treatment of gastrointestinal malignancies. We also offer minimally invasive treatments to treat cancers that affect the gastrointestinal (GI) tract. These include esophagealgastricpancreaticliver and colorectal cancers or cancers that have metastasized to the GI tract, such as lung or breast cancer. The team also treats precancerous conditions, such as Barrett’s esophagus, and provides relief from cancer-related symptoms. The goal is to help each patient receive comprehensive, up-to-date, personalized treatment. The team strives to maintain quality of life for all patients with gastrointestinal malignancies.

Experienced GI team

At CTCA® Tulsa, you’ll work with a multidisciplinary team of physicians who have expertise in performing cancer-related procedures in the GI tract. This team works together to understand your individual needs and comprehensive, personalized treatments while meeting regularly to discuss your progress and modify your treatment accordingly.

When you arrive at our hospital, your care team will review your symptoms with you and obtain a health history. Then, we’ll use diagnostic tools and interventional procedures to evaluate the tumor(s). We are dedicated to providing a diagnosis and treatment plan within days of your arrival to the facility. After you are diagnosed, we work with you to identify treatments tailored to your specific needs.

Treatment advances

We provide a wide range of treatment options for GI cancers. The team uses advanced technologies to look at the GI tract more thoroughly, usually with minimally invasive procedures. We may apply innovative techniques, such as ablative treatments, to help relieve obstructions in the GI tract and pain caused by tumors.

For example, for pancreatic cancer patients, we may perform therapeutic endoscopic ultrasound (EUS) to relieve pain (celiac plexus neurolysis). Cryotherapy or esophageal stents may be used to treat patients having difficulty with swallowing caused by esophageal tumors. We may also use EUS to place fiducial markers in pancreatic tumors prior to radiation therapy for more precise targeting of tumors. 

Throughout your treatment, your care team will use multiple measures to help reduce symptoms and improve quality of life. The gastroenterologists work closely with the hospital’s oncologists and surgeons to manage side effects from chemotherapy or surgical procedures. We also work with a team of dietitians to provide nutritional support throughout cancer treatment.

Other treatments that may be available for patients with GI cancers include:

Small bowel enteroscopy: This minimally invasive option allows doctors to navigate the small intestine and perform diagnostic or treatment procedures.

Photodynamic therapy: This innovative treatment uses light-activated drugs and a light source to kill cancer cells. This treatment option may be used for multiple types of GI cancer and other cancers, such as lung cancer.

Biliary radiofrequency ablation (RFA): In this procedure, a radiologist uses an electric current to destroy cancer cells. RFA is often used as a palliative procedure to clear obstructed stents and remove tumors that may be causing pain. This treatment may be an option for patients who are not candidates for chemotherapy or surgery and whose disease has progressed while on chemotherapy.

"The treatments were difficult to get through at times. My hands became numb and I had very painful mouth sores that lasted throughout chemotherapy. After the six hours of chemotherapy infusion, there were times when I could not make it to my room unassisted. But the truth is, I never had to make it to my room unassisted. There was always someone there to help. My care team did their best to help reduce the pain of the mouth sores and to provide comfort in whatever way they could."

GI cancer clinical trials

Our team of gastroenterologists conducts clinical trials as part of the CTCA commitment to providing new and innovative treatment options when possible. As part of this commitment, we may offer clinical trials to patients with GI cancers who meet certain criteria. These trials study potential advancements in treatment approaches, which may include targeted therapy, immunotherapy, offering some qualifying patients options that may not otherwise have been available to them.
