Better quality of life one year after curative treatment for head and neck cancer may correlate with longer-term survival
Quality of life measured one year after curative treatment
for head and neck cancer appears to be associated with longer-term survival, according
to an article in the January issue of Archives of Otolaryngology - Head &
Neck Surgery.
Several studies have provided evidence that
quality of life (QOL) might be associated with long-term survival
in cancer patients, according to background information in the article.
However, many studies have examined QOL in patients whose cancers
were advanced and were in palliative care, so their results might
not apply to people undergoing curative treatment. Previous studies
on head and neck cancer patients had assessed QOL before they entered
treatment and found no association with survival, according to the
authors.
Dr. Hisham M. Mehanna, of University Hospitals Coventry and Warwickshire,
England, and Dr. Randall P. Morton, Auckland City Hospital, New
Zealand, assessed whether pretreatment and post-treatment QOL was
associated with long-term survival in patients with head and neck
cancers. A group of 200 consecutive patients completed a QOL questionnaire
when they were diagnosed with their disease and 12 months later,
after treatment, if they were free of recurrent cancer.
After 10 years, 136 (68 percent) of the patients died, 48 were
alive and the status of 16 was unknown. Those who had a lower QOL
one year after treatment?as well as those who had head and neck
pain?were more likely to have died.
“We hypothesized that, intuitively, it is more likely that the
steady-state QOL, after patients had adjusted to the effects of
the diagnosis and of treatment and had mobilized their coping strategies
accordingly, would be the determinant of long-term survival, rather
than pretreatment QOL,” the authors reported. “This was based on
the observations that QOL status usually decreases noticeably during
and in the period immediately after treatment and that patients
return to a steady-state QOL at about one year after diagnosis.
The findings of this study seem to corroborate this premise.”
“However, the observed associations between survival benefit and
one-year QOL may be confounded by comorbidity, which was not measured
and deserves further investigation,” they concluded.
