Fertility Guidelines Aim to Jumpstart Conversations
Young cancer patients and their doctors sometimes overlook a fairly
common side effect of cancer treatment: infertility. Recognizing this,
the American Society of Clinical Oncology (ASCO) recently released
guidelines for addressing the issue.
Doctors should talk to patients about the possibility of infertility
early on when discussing treatment, according to the new ASCO
guidelines, and be prepared to refer patients to specialists who can
help them choose a method of preserving their fertility when
appropriate.
The guidelines mark a shift in thinking about cancer treatment and
survivorship -- one that many doctors and patients say is overdue.
"We're at this amazing crossroads where survival rates are higher
than they've ever been, and at the same time there are more reproductive
options than there were before," said Lindsay Beck, co-author of the new
guidelines and founder of the patient group Fertile Hope. "If you don't
have that discussion early on, patients will miss their opportunity."
Beck began Fertile Hope in 2001 after her own struggles to find a way
to preserve her fertility in the face of cancer treatment. The group
provides information and financial assistance to young cancer patients
who need fertility preservation procedures. She says oncologists haven't
been doing enough to inform patients of the treatment risks or fertility
preservation options.
"I don't think they're maliciously not doing it," she emphasized.
"Oncologists aren't reproductive specialists, so this [guideline] gives
them information on what's available today."
Greater Focus on Quality of Survivorship
Other experts agree there's room for improvement in the way doctors
address the issue with young patients.
"Historically, many of the cancers we cure today were not cured in
the past," said gynecological oncologist Carolyn Runowicz, MD, national
volunteer president of the American Cancer Society and director of the
Carole and Ray Neag Comprehensive Cancer Center at the University of
Connecticut Health Center. She was not involved in creating the
guidelines.
"Now with earlier detection and better treatment, we are increasing
the number of cancer survivors," she said. "For many, issues of
fertility arise."
That was certainly the case for Antoinette Ramos of California, who
was diagnosed with Hodgkin disease last year at age 25. Her doctor
mentioned the possibility of infertility after treatment only in
passing, she said.
"He said, 'Don't worry, I've had lots of patients who've gone on to
have children,' " Ramos recalled.
Ramos was single, and still is, but had always planned to have
children someday. The possibility of infertility came as a shock to her.
"The fact that that choice might be taken away from me really rocked
my whole existence," she said. "I didn't cry when I found out I had
cancer -- I cried when I found out it could affect my fertility."
With the help of Fertile Hope, Ramos froze 19 of her eggs before
beginning chemotherapy.
Beyond Sperm and Embryo Freezing
The new ASCO guidelines are informative for oncologists who may not
know very much about modern methods of fertility preservation, according
to Runowicz. They list the various cancer treatments that can cause
infertility, and detail both proven and experimental methods of
fertility preservation.
For men, sperm freezing is both effective and well-established, the
guideline says, noting that sperm should be collected before cancer
therapy begins because even one course of treatment can cause damage.
Hormonal therapy, on the other hand, has not been shown to be
successful. Shielding the testicles from radiation is another
possibility, but one that requires considerable expertise to be done
properly.
For women, embryo freezing is the most established technique, but it
may not be an option if a woman has no partner or cannot delay treatment
long enough for egg harvesting. Freezing eggs alone presents the same
timing problems and is still a relatively new and unstudied technique.
Shielding the ovaries from radiation, or moving them out of the field of
radiation, may be feasible for some women. Likewise, new surgical
techniques may help women with certain cancers preserve their fertility.
Few options exist to preserve fertility in children who have not yet
reached puberty, the guidelines note. Experimental techniques include
freezing sections of tissue from the ovaries or testicles, in hopes that
implanting them into the body later will restore fertility. But it is
not certain how well these strategies might work.
Case-By-Case Approach
Deciding which fertility preservation treatment to use depends on
each person's particular situation, said reproductive endocrinologist
Kutluk Oktay, MD, co-chair of the committee that wrote the new
guidelines. He is director of the fertility preservation program and
associate professor at Weill Medical College of Cornell University in
New York.
"So far the most established method is embryo freezing, but even
there, there are areas that need further research," he said.
For instance, Oktay is studying ways to help women with breast cancer
safely stimulate egg production without increasing estrogen levels,
which can fuel breast cancer growth. Other methods, like ovarian tissue
freezing, are still so new there simply isn't any long-term data to show
if they are effective or safe.
"The downside is most of the technologies we use have not been around
for too long and don't have a long track record," he said, "but whatever
we have is promising."
Oncologists aren't the only ones who will find the new guidelines
useful, Oktay stressed. Other diseases can also cause infertility.
"These technologies are good for anyone whose fertility is threatened
for any reason," he said. |
