PET scans useful for some cancer treatment, but how do patients fare?

Positron emission tomography or PET scans can help clinicians diagnose and treat some cancers, but it is not clear yet whether the imaging technology helps people with cancer live longer and healthier lives, according to a comprehensive review by the UK National Health Service.

1. Quantitative PET imaging finds early determination of effectiveness of cancer treatment
   10-23-2007 · EurekAlert!
   With positron emission tomography imaging, seeing is believing: evaluating a patient's response to chemotherapy for non-Hodgkin lymphoma typically involves visual interpretation of scans of cancer tumors. Researchers have found that measuring a quantitative index -- one that reflects the reduction of metabolic activity after chemotherapy first begins -- adds accurate information about patients' responses to first-line chemotherapy, according to a study in the October issue of the Journal of Nuclear Medicine.

2. PET imaging significantly enhances standard imaging in lung cancer staging
   11-27-2007 · EurekAlert!
   Positron emission tomography is a useful diagnostic tool that supports the need for more accurate staging of lung cancer and improved treatment for patients, concludes an extensive systematic review published online today in Journal of National Cancer Institute.

3. What's going on in the body? Advanced time-of-flight PET takes a superior 'look'
   06-04-2007 · EurekAlert!
   Moving from computer simulation to patient images, researchers are now demonstrating the benefits that time-of-flight/PET imaging can provide for cancer patients. The result? Superior images and shorter patient scan times for starters, according to a study released at the 54th Annual Meeting of SNM, the world's largest society for molecular imaging and nuclear medicine professionals, June 2-6 in Washington, D.C.

4. PET scan shows during treatment if radiation is shrinking lung tumor, U-M study shows
   07-18-2007 · EurekAlert!
   Lung cancer patients may not need to wait till their radiation treatment is over to know if it worked. A PET scan several weeks after starting radiation treatment for lung cancer can indicate whether the tumor will respond to the treatment, according to a new study by researchers at the University of Michigan Comprehensive Cancer Center.

5. Post-treatment PET scans can reassure cervical cancer patients
   11-20-2007 · EurekAlert!
   Whole-body PET scans done three months after completion of cervical cancer therapy can ensure that patients are disease-free or warn that further interventions are needed, according to a study at Washington University School of Medicine in St. Louis.

6. PET scans can accurately detect a breast tumor's response to chemotherapy
   09-25-2007 · EurekAlert!
   Researchers in Australia have shown that positron emission tomography that uses a radioactive sugar molecule is more useful than mammography and ultrasound in predicting a breast tumor's response to chemotherapy and, therefore, the patient's ultimate likelihood of survival. The research was presented at the European Cancer Conference in Barcelona today.

7. How can we know early who will benefit from tumor target therapy?
   11-21-2007 · EurekAlert!
   A 55-year-old male patient had developed advanced hepatic metastasis and peritoneal carcinomatosis after remnant gastric cancer resection three months earlier. The patient only received target therapy, including Cetuximab plus recombinant human endostatin treatment. Anti-tumor activity assessed by 18F-fluorodeoxyglucose positron emission tomography/computer tomography scan at baseline, then every four weeks afterward showed that 18FDG-PET/CT could make an early prediction of the response to cetuximab plus Endostar in such clinical situations.

8. Researchers identify key gene that may be a marker of breast cancer metastasis
   04-18-2007 · EurekAlert!
   Researchers at Fox Chase Cancer Center have identified an important gene involved in the spread of breast cancer that has developed resistance to long-term estrogen deprivation. The gene may prove to be a useful marker for predicting which patients have the greatest risk of breast cancer recurrence so their doctors can offer the most appropriate treatment plan.

9. PET scans track small tumors after stereotactic body radiotherapy
   10-28-2007 · EurekAlert!
   Readily available CT screening for lung cancer is increasing the discovery of small, primary lung cancers. For many, a radiation technique called stereotactic body radiotherapy presents a less invasive treatment option to surgery that is typically offered to nonsurgical candidates. In a study presented today researchers present data showing metabolic response monitored by FDG PET may be an early surrogate for local treatment failure which may allow timely salvage surgery if deemed necessary.

    06-04-2007 · EurekAlert!
    Through participation in a government-sponsored multi-year study, researchers at the Comprehensive Cancer Center at Wake Forest University have helped confirm that arsenic trioxide -- marketed as Trisenox -- significantly improves patient survival when coupled with standard chemotherapy treatment in newly diagnosed patients with acute promyelocytic leukemia, or APL.
