Stomach Cancer

Our Approach
At City of Hope, a multidisciplinary team of nationally recognized experts in the research, diagnosis and treatment of gastrointestinal cancer provides outstanding medical care to patients with stomach cancer, also known as gastric cancer. We are experts in treating patients with all stages and all types of stomach cancer, including:
  • Adenocarcinoma
  • Sarcomas
  • Lymphomas
City of Hope researchers and physicians have pioneered new approaches for stomach cancer. We use aggressive therapies, minimally invasive and robotic-assisted surgery, and state-of-the-art technologies and highly compassionate care to give patients the best possible outcomes. Treatment for stomach cancer may involve:
  • Surgery (gastrectomy)
  • Chemotherapy
  • Radioimmunotherapy
  • Radiation therapy, including helical TomoTherapy
Through our active clinical trials research program — among the most extensive in the nation — we can often provide patients with access to promising new anticancer drugs and technologies not available elsewhere.

Risk Factors and Symptoms

Risk Factors
Many common factors are associated with the risk of developing stomach cancer. Some of these include:
  • Age over 50
  • Male gender
  • History of chronic stomach infection with Helicobacter pylori
  • Asian/Pacific Islander, Hispanic-American or African-American heritage
  • Heavy consumption of smoked, salted and pickled foods
  • Cigarette smoking
  • Extreme obesity
  • Previous stomach surgery
  • Pernicious anemia
  • Menetrier disease leading to atrophic gastritis
  • Hereditary nonpolyposis colorectal cancer
  • Familial adenomatous polyposis
  • Family history of stomach cancer
Signs and Symptoms

Early stomach cancer often does not cause clear symptoms. A stomach cancer (tumor) may grow very large before it causes symptoms.
In the early stages a patient may experience:
  • Indigestion or stomach discomfort
  • A bloated feeling after eating
  • Mild nausea
  • Loss of appetite
  • Heartburn

In more advanced stages a patient may have:

  • Pain in the stomach
  • Blood in the stool (dark black or red)
  • Vomiting
  • Weight loss


Diagnostic tests may include:
  • Physical exam and history
  • Gastroscopy: A thin, lighted tube called a gastroscope is inserted through the mouth and guided into the stomach. A local anesthetic or other medicine may be given to minimize discomfort.
  • Barium swallow/Upper GI series: A series of X-rays is taken after the patient drinks a liquid to improve the visualization of the inside of the upper gastrointestinal tract.
  • Biopsy: If tests indicate that stomach tissue seems abnormal, a small sample may be taken for examination under a microscope to check for cancer cells. This is called a biopsy.


A patient’s chances of recovery (prognosis) as well as medical decisions about the most promising treatment options, depend on the specific type of stomach cancer, the stage of the cancer (whether it is found only in the stomach or has spread to other places in the body), as well as the patient’s overall health. Stomach cancers are frequently diagnosed at an advanced stage, when they may be more difficult to cure.
At City of Hope, our multidisciplinary approach to treating gastric cancer is designed to enhance the evaluation and treatment of patients at all stages of the disease. Care is provided by the departments of  Surgical Oncology, Medical Oncology, Gastroenterology and  Radiation Oncology working together to achieve the best possible outcomes.
Treatment of gastric cancer often requires the removal of affected stomach tissue. This surgical procedure, called a gastrectomy, may be partial or total, depending on the location of the tumor. Lymph nodes around the stomach may also be removed to reduce the risk of cancer cells spreading to other parts of the body.
At City of Hope, our surgeons specialize in minimally invasive procedures performed by laparoscopy. These procedures use small keyhole incisions rather than the large incisions used in traditional open surgery. Results with laparoscopy are comparable to open surgery, but often with less pain, reduced loss of blood, faster recovery, shorter hospital stays and a lower risk of post-operative complications.
City of Hope surgeons are also highly skilled in robotic-assisted surgery, using the most advanced da vinci S Surgical System. A surgeon directs and controls the movements of a specially designed robot, equipped with a camera and miniature surgical tools. At the same time, a sophisticated, computerized imaging system provides real-time three-dimensional views of the surgical area, with better visualization than can be achieved with the surgeon’s eye alone.
Chemotherapy and Radioimmunotherapy
Chemotherapy refers to drugs that are given either intravenously or orally to treat cancer. Chemotherapy may be combined with other treatments, and is often used to combat cancers that have spread beyond the stomach.
At City of Hope, chemotherapy may be combined with radiation therapy or with radioimmunotherapy (treatment with a radioactive substance linked to an antibody that can attack the tumor and destroy it).
Radiation Therapy
Radiation is a form of energy that has long been used to treat many kinds of cancers. In stomach cancer, radiation may be given to relieve pain, in combination with chemotherapy, or after surgery to minimize the risk of recurrence. Treatments in which beams of energy are directed at the tumor from an outside source are referred to as external beam radiation.
At City of Hope, external beam radiation treatments may include:
  • Three-dimensional conformal therapy
  • Helical TomoTherapy
Considered the most advanced radiation therapy available, helical TomoTherapy allows doctors to target and destroy cancer cells very precisely while sparing healthy tissues nearby. City of Hope was the first in the western U.S. to provide treatment for stomach cancer using this therapy.


All of our patients have access to the  Sheri & Les Biller Patient and Family Resource Center, which offers a wide array of support and educational services. Patients and loved ones may work with a coordinated group of social workers, psychiatrists, psychologists, patient navigators, pain management specialists and spiritual care providers at the center, as well as participate in programs such as music therapy, meditation and many others.

Research/Clinical Trials

City of Hope has long been a leader in gastrointestinal cancer research, including
stomach cancer. Multiple clinical trials are ongoing, offering patients access to new and advanced treatments involving chemotherapy, radioimmunotherapy and radiation. As a patient at City of Hope, you may qualify to participate in a test of these new investigational therapies.
