Surgically removing residual gastrointestinal stromal tumors in patients who respond to imatinib therapy significantly increased time to tumor progression to 88 months, compared with 43 months using imatinib alone, based on findings from a retrospective study of 134 patients.

After controlling for the effects of other risk factors, the surgery decreased threefold the likelihood of disease progression and decreased fivefold the risk of death, Dr. Seong Joon Park reported in a press briefing sponsored by the American Society of Clinical Oncology (ASCO). The press conference was held in advance of at a meeting on gastrointestinal cancers sponsored by ASCO and three other cancer organizations.

The findings support the widely adopted practice of removing residual tumors in these patients, despite the retrospective and observational design of the study, Dr. Park said. A prospective European study of similar design to this one terminated early due to poor patient enrollment. "It’s really hard to conduct a prospective study of this design," said Dr. Park of Asan Medical Center, Seoul, South Korea.
