RADIATION ALONE AFTER SURGERY STILL THE STANDARD FOR HEAD AND NECK CANCER
A preliminary study has found no advantage to adding chemotherapy to
radiation after surgery for treating advanced head and neck cancer
patients. The findings of the research, to be presented at the American
Society of Clinical Oncology meeting May 18, appear to set aside earlier
data suggesting that a combination of chemotherapy and radiation would
improve the odds of staying cancer-free after surgery. Results are
published in abstract # 903 in the ASCO Program/Proceedings.
Recurrence and spread of head and neck cancer is common and fewer than half
of these patients are expected to survive past five years. "Early studies
suggested that combining certain chemotherapy drugs and radiation may have
a synergistic effect in these patients," says Arlene Forastiere, M.D.,
professor of oncology and otolaryngology at the Johns Hopkins Kimmel Cancer
Center and medical oncology co-chair of the study. "Our current study shows
that adding the chemotherapy drug cisplatin to standard radiation treatment
does not significantly reduce recurrence."
The study evaluated 407 patients who had surgery to remove their cancer and
were at high risk for recurrence. After surgery, patients in one group
received radiation alone and, in a second group, a combination of cisplatin
and radiation.
In a preliminary analysis after two years, researchers found no significant
difference between the two groups in the percentage of patients remaining
cancer-free. The cancer recurred in 26 percent of patients receiving
radiation alone and in 20 percent of those receiving chemotherapy and
radiation. There also was no significant difference between the two groups
in overall survival --63 percent in the combination therapy group versus 57
percent who received radiation only.
Just over half (58 percent) of the patients getting combination therapy
were able to take all three doses of chemotherapy. The others did not
tolerate the full dose. These patients experienced more side effects, such
as lower blood counts, nausea and mouth soreness, than those receiving
radiation alone. Three patients (two percent of the total evaluated)
receiving combination therapy died during the study. There were no deaths
during the study in the radiation-only group. "The fact that many of these
patients receiving combination therapy could not handle all of the
chemotherapy suggests that we should look in another direction," explains
Forastiere. "Adding targeted drugs and those with less side effects may be
a better alternative."
For now, researchers say that the standard treatment for advanced head and
neck cancer patients who have had surgery will remain radiation therapy alone.
The researchers studied head and neck cancers located in the larynx, or
voice box, the pharynx, which is part of the throat, and the oral cavity.
These cancers are diagnosed in approximately 37,800 patients every year,
and about 11,100 Americans will die from the disease.
This research was funded by the National Cancer Institute.
