Gastrointestinal stromal tumors, or GISTs for short, affect up to 10,000 Americans each year. For the past few years, Gleevec has been known as the wonder drug for these patients, but it can stop working.
Now, researchers are looking to the next generation of drugs to save lives.
The game of life took a devastating turn for Rudolph Russo when he was diagnosed with the digestive tract cancer.

“There are mornings when I say, ‘Damn it, that’s the end of this,’ then I’ll wake up and get back doing what I am supposed to be doing,” he said.
For a few years, the drug Gleevec kept Russo’s cancer in check. But like many patients, he became resistant.
“It was therefore really more painful when the resistance came on because people came back from the brink of death, and then to have the resistance build up and have the tumors come back was particularly painful,” George Demetri, an oncologist from Dana-Farber Cancer Institute in Boston, said.
Now, Russo takes the drug Sutent as part of a clinical trial. Demetri says unlike Gleevec, Sutent shuts down the growth of blood vessels that feed the cancer.
“The new drug is able to shut down not just one signal in the cells but multiple signals,” he said.

In his study, patients who took the new drug lived almost twice as long as those who didn’t. Russo says it has given him precious time with his grandkids.
“This is a drug that is keeping me alive,? he said. ?If I did not do anything, I would be dead.?
He’s a fighter and Sutent has given him another chance to prove it.
Doctors believe Sutent can help fight other diseases like kidney and breast cancer.
Sutent is now in the process of getting approved by the FDA. The drug does pose side effects, like thinning of the skin, diarrhea and nausea.

BACKGROUND:
About 21,860 new cases of stomach cancer were diagnosed in 2005, according to the American Cancer Society. About 11,550 people will die of this disease. Stomach cancer is more common in older populations. Two-thirds of the people found to have stomach cancer are older than age 65. Some of the risk factors for stomach cancer include being male, smoking, alcohol abuse and ethnicity. The rate of stomach cancer is higher in Hispanics and blacks than in non-Hispanic whites. The highest rates are seen in Asian/Pacific Islanders. Some doctors believe the bacteria Helicobacter pylori, a common cause of stomach ulcers, is a major contributor to stomach cancer. Also, the Epstein Barr virus, the virus that causes mono, has been found in some stomach cancers. Scientists believe most of the causes of stomach cancer are things that happen after birth. This cancer is not usually hereditary.
GASTROINTESTINAL STROMAL TUMORS:
Gastrointestinal stromal tumors (GISTs) are a rare subset of stomach cancer. Researchers believe they form from cells in the wall of the stomach called interstitial cells of Cajal. These cancers can be found anywhere in the intestinal tract. About 5,000 people will be diagnosed with this type of stomach cancer each year.
TREATMENT:
Treatment for GIST includes surgery, radiation and chemotherapy. The drug Gleevec, originally used to treat patients with chronic myelogenous leukemia, has also been useful in the treatment of this disease. Gleevec, or imatinib mesylate, blocks the tumor cells’ ability to grow and divide. However, Gleevec is not a long-term solution for cancers. The affects seem to wear off after about two years.
NEW TREATMENT:
Doctors at the Dana-Farber Cancer Institute in Boston are testing the effectiveness of a new drug called SUTENT/SU11248 (sunitinib malate). The drug more than doubled survival and significantly reduced tumor growth and spread in a Phase III study. George Demetri, M.D., of the Dana-Farber Cancer Institute, says the drug works by telling the body to turn off the growth of blood vessels to the tumor. “It actually shuts off those signals, so the body doesn’t feed those cancers,” says Dr. Demetri. Results from a study of more than 300 GIST patients resistant to or intolerant of the standard treatment of Gleevec, showed Sutent significantly prolonged the time to tumor progression. It took a little more than six months for tumors to start growing again with Sutent. It took just one and a half months for tumors to start growing again for patients in the control groups. Sutent also reduced the risk of death by about 50 percent compared to placebo. This new drug may be used to treat other cancers in the future. It has been tested on breast cancer and kidney cancer. As of December 2005, the FDA has not yet approved this drug for widespread use.

TAYLOR RIDGE, Ill. – The tears Brandi Osborn shed as she neared the finish line of the 26.2-mile Walt Disney Marathon on Jan. 8 weren’t from physical exertion.
They were a symbol of the joy the Taylor Ridge, Ill., resident felt as her months of hope and hard work turned to triumph.
Osborn was unsure she could complete the challenge of walking the trek as she prepared to be part of the Leukemia & Lymphoma Society Team in Training.
The team gathers pledges to participate in the annual walk and donates that money to the Leukemia & Lymphoma Society.
Osborn said the strong spirit of encouragement coming from the crowd as she was finishing filled her with emotion.
Among the calls of hundreds of well-wishers Osborn, 53, recalls a strong voice that rose above the sea of cheers.
“One man said, ‘Hey Brandi from Illinois, I’m a soldier from Kankakee, (Ill.) I just got back from Iraq and I haven’t been home yet,’” Osborn said.
“I told him, ‘Well, you’re a hero,’ and he said, ‘Not today. Today, you’re a hero.’”
Osborn’s seven hour and 14 minute journey began in October 2004, after her brother, Randy Osborn, her aunt, Jane Mitchell, and an uncle to her daughter Tracey Burke, Jim Whitehall, all died of cancer within two weeks of each other.
Osborn and Burke, 36, were saddened, but they wanted to direct their grief in a positive direction. That’s when the mother and daughter decided to help other people who are still fighting their battle with cancer by joining the Leukemia & Lymphoma Society Team in Training.
The Leukemia & Lymphoma Society, a national, voluntary health agency, helped finance the development of a new drug called Gleevec which can normalize white blood cells in cancer patients with chronic myelogenous leukemia. The society also helps people undergoing treatment for leukemia and lymphoma pay for expenses related to their medical care.
Osborn and Burke of Edgington, Ill., worked out together through the fall of 2005 between their work hours. Osborn is employed at the Edgington Hardware Store and Burke works at Heinz in Muscatine. But health problems prevented Burke from making the walk.
Osborn said she received encouragement and helpful information from professional runner and coach, Adam White of Peoria, who donated his expertise as Osborn’s trainer for the event.
The walk was the final part of the challenge.
Prospective walkers must collect $3,400 in pledges to participate and those don’t collect enough, give what they do have to the Leukemia & Lymphoma Society.
Larry McDowell, owner of Dooley’s Sports Bar in Andalusia, Ill., helped Osborn stage a fund-raiser there in October which helped put her over the top.
In all, she raised $4,000 for the society.
When she returned from Florida, McDowell and his wife presented Osborn with a custom-made trophy he ordered for her.
“He hugged me and told me how proud he and his wife Carol were,” said Osborn.
Team in Training members walk for a patient honoree, which is someone who has battled leukemia, lymphoma, myeloma or Hodgkin’s disease.
Osborn represented Edgington resident Marvin Keller, who was diagnosed with lymphoma.
The experience also provided Osborn with the opportunity to begin another important relationship. Media coverage of Osborn’s ambition to be in the marathon reached New Mexico and Osborn’s step-sister, Jean Shepard, whom Osborn had never met.
“When my real dad died, my stepfather, Dick Osborn, adopted me,” said Osborn. Dick Osborn, who died in 1988, had children from a previous marriage that Brandi hadn’t met, including Jean Shepard. “We got in touch because she read the article on the Internet, and it has meant so much to me over these past months,” said Osborn.
Osborn said she doesn’t know if she’ll do another marathon next year, but she does plan to take to the track again. And she said she’d be happy to have others join her.
