Newswise — A new study led by a University of Colorado
Cancer Center member recently published in the journal Quality of Life Research
shows that in young, female cancer survivors, quality of life is significantly
impaired long after treatment. The study compared 59 cancer survivors to 66
healthy controls and found that, as expected, cancer survivors showed higher
stress and anxiety than the general population. Of note, survivors reported
particular stress around the issues of sexual problems, physical pain and
fatigue. The study also measured hormone levels reflecting woman’s number of
eggs, and showed that among young, female cancer survivors, those with reassuring
fertility status were likely to report higher quality of life once treatment
ends.
“What it came down to was a woman’s opinion of her own
fertility status after cancer treatment,” says Laxmi Kondapalli, MD, MSCE,
director of the CU Cancer Center Oncofertility Program.
See, there was one intervening step between normal ovarian
reserve and quality of life: the regularity of a woman’s menstrual cycle after
undergoing chemotherapy and/or radiation treatment for cancer. All women lose a
certain number of eggs during these treatments, but those with higher baseline
reserve are more likely to withstand the treatment with their overall fertility
unaffected. Women with lower ovarian reserve at baseline are more likely to
have impaired fertility after treatment.
“But it wasn’t the lab and ultrasound markers of ovarian
reserve alone that affected quality of life,” Kondapalli says. “It was a
woman’s opinion of her fertility status based on her menstrual cycle that had
the most impact on quality of life.”
Following cancer treatment, many women think that if they
maintain regular menstrual cycles, their fertility is preserved, and that if
their menstrual cycles become irregular, then they are likely infertile due to
treatment.
“This isn’t necessarily the case, because we are finding
that menstrual cyclicity is a poor predictor of fertility status in these
young, female cancer survivors,” Kondapalli says. “Survivors may be falsely
reassured if they resume normal periods, or they may be unnecessarily stressed
if they don’t get regular periods after cancer treatment.”
According to Kondapalli, women with high ovarian reserve are
less likely to experience symptoms of early menopause after cancer treatment.
And it is these symptoms that go on to influence young patients’ quality of
life.
“I think what our study demonstrates is that clearly there
are many components that impact a survivor’s quality of life after cancer
treatment. Although objective markers of ovarian reserve play an important
role, a woman’s perception of her own fertility status was more influential in
her overall quality of life,” Kondapalli says.
Understanding the factors that influence quality of life in
this population may help identify ways to manage late effects of treatment and
improve comprehensive survivorship care.
