PET accurately identifies esophageal cancer patients' positive responses to chemotherapy

June 04, 2007

Molecular imaging opens door to tailoring treatment based on cancer tumor biology, report researchers at SNM's 54th Annual Meeting June 2-6 in Washington, D.C.

WASHINGTON, D.C.-Early metabolic imaging with positron emission tomography (PET) accurately identifies patients responding to chemotherapy for esophageal cancer, noted German researchers at the 54th Annual Meeting of SNM, the world's largest society for molecular imaging and nuclear medicine professionals.




"This is the first study to apply PET results from early metabolic response assessment to clinical decision making in the treatment of common solid tumors," said Ken Herrmann, a resident in the department of nuclear medicine at Technical University in Munich, Germany. "The outcome for metabolic responders turned out to be remarkably favorable compared to metabolic non-responders. Our results show that PET helps select patients who are benefiting from chemotherapy," he noted. "Based on our early response assessment, the course is set for tailoring multimodality treatment on the basis of tumor biology," explained Herrmann.

In addition, PET-response-guided treatment "helped circumvent the administration of inefficient chemotherapy to patients with no metabolic response-without compromising their outcome," added Herrmann.

Less well-known than lung cancer-but no less serious-esophageal cancer starts in the inner layer of the esophagus, the 10-inch long tube that connects your throat and stomach. Adenocarcinoma is esophageal cancer that begins in cells that make and release mucus and other fluids. In this country, more than 14,000 persons are expected to die from the disease, and more than 15,000 new cases will be diagnosed this year.

The MUNICON trial, conducted from May 2003 through August 2005, was the first study conducted to apply PET results from early metabolic response assessment to clinical decision-making in the treatment of common solid tumors, said Herrmann. "This clinical trial delineated how response-guided treatment algorithms may be applied to clinical practice, serving as a model for other malignant diseases-like lung, head and neck or ovarian cancer-and providing information to alter treatment and patient management," he explained. "The results of our study delineate how response-guided treatment algorithms can be applied in clinical practice in the future," said Herrmann.

PET is a powerful medical imaging procedure that noninvasively demonstrates the function of organs and tissues. When PET is used to image cancer, a radiopharmaceutical (such as fluorodeoxyglucose or FDG, which which is a radioactive analog of sugar) is injected into the vein of a patient. Cancer cells metabolize sugar at higher rates than normal cells, and the radiopharmaceutical is taken up in higher concentrations to cancerous areas. PET scans show where FDG is by tracking photons given off by the radioactive tracer. PET scanning provides information at a molecular level-not available through other procedures-about the body's chemistry, metabolic activity and body function.
