The importance of quality of life
during and after treatment for
cervical cancer has been ignored
for too long. The pervasive attitude
that focuses on cure, with
morbidity an afterthought, is still
paramount in many patients' and oncologists'
minds. However, at the insistence
of patients and families, many
clinicians have recognized and started
to address these issues over the
past 2 decades.
Despite the best intentions, quantification
of quality of life is complex
and difficult. Evaluation of the tools
used to measure and assess quality of
life is essential. A study comparing
patients' evaluations of the European
Organization for Research and Treatment
of Cancer (EORTC) quality of
life questionnaire (QLQ)-C30 with
their own quality of life suggested
that our methodology warrants improvement.[

Dr. Carter and colleagues are to be
congratulated on their efforts. As noted
in their review, most patients hesitate
to bring up issues of sexuality
and fertility, and their needs go unmet.
Patients will frequently tell nonmedical
health professionals about
their quality-of-life concerns but will not mention a word to their treating
physicians. Perhaps this reflects the
patient's perception of the physician's
discomfort in dealing with the subject
or the length of time afforded each
visit.
An important point that the authors
may have overlooked is the
well-documented fact that sexual dysfunction
in many patients starts with
symptoms that eventually lead to the
diagnosis of cervical cancer, such as
abnormal bleeding or pain.[2] It thus
becomes easy to conceptualize how
similar symptoms associated with intercourse
and due to noncancerous
causes can lead to further dysfunction.
Furthermore, a significant proportion
of patients develop the
irrational belief that sexual intercourse
may predispose them to recurrence.
This may be rooted in their readings
that cervical cancer (due to its relationship
with human papillomavirus)
is a sexually transmitted disease.[3] If
sex caused the cancer, it is reasonable
for laypersons to surmise that it may
predispose to a recurrence.
Early-Stage Cervical Cancer
Although no direct comparisons of
sexuality in patients treated with
surgery vs radiation are available, indirect
evidence suggests that posttreatment
sexual functioning is disrupted
less with surgery.[4,5] Possible explanations
for this include the fact
that ovarian function can be preserved,
and the caliber, distensibility, and ability
of the vagina to lubricate (through transudation) are maintained. Furthermore,
most patients prefer the idea of
removing the cancer, rather than irradiating
it in situ. However, all of the
above must be interpreted in light of
the fact that, in general, patients treated
with radiation therapy are not comparable
to patients treated with
surgery; they tend to have larger tumors,
be older in age, and have more
comorbidities.
Fertility Preservation
Fertility (in the natural sense) can
be preserved surgically with the use
of a radical trachelectomy. However,
intracavitary irradiation in the absence
of external-beam irradiation has also
been used as a method of preserving
fertility.[6] New reproductive technologies
have expanded the definition of
maintaining fertility. Surgical removal
of the ovaries or radiation-induced
ovarian failure does not necessarily
signify the inability to procreate. Cryopreservation
of embryos, mature oocytes,
and even ovarian tissue is now
being performed.[7]
Should radical trachelectomy be
offered to women with no desire to
preserve fertility, solely to preserve
the uterus? Presently, most clinicians
do not feel that the small incremental
risks theoretically associated with this
surgery over radical hysterectomy justify
its use. However, patients may
feel differently. In our series after
2 years of follow-up, approximately
33% of women who underwent radical trachelectomy had not attempted
conception. On detailed questioning,
many of these women had little prospect
or interest in pregnancy, yet took
comfort in the fact that they had done
all they could to preserve their fertility.
Recurrent Cervical Cancer
Treatment of recurrence presents a
somewhat different scenario. At diagnosis,
stage I cervical cancers are
associated with an 85% to 90% probability
of cure. With this in mind, it is
not difficult to look beyond treatment
and address issues of sexuality and
fertility. However, in the setting of
recurrent disease, with cure rates varying
from 40% to 60%, survival is very
much threatened. Patients previously
treated with surgery alone tend to receive
radiation therapy, and conversely,
patients previously treated with
radiation therapy alone tend to be candidates
for pelvic exenteration. The
latter procedure represents the ultimate
in surgical aggressiveness, producing
obvious changes in body
function.
In the 1970s and 1980s, surgeons
addressed the issue of sexuality by
offering construction of a neovagina
(using muscle or skin) at the time of
surgery. Sexuality was interpreted as
intercourse, and success was measured
by the length and size of the resulting
vagina, not its functional status or the
patient's satisfaction. The naivety associated
with such rudimentary interpretation and evaluation is readily evident.
Not unexpectedly, pelvic exenteration
has been well documented
to be associated with profound effects
on quality of life, body image,
and sexual functioning.[8,9]
The Future
What then is the best management?
Despite the suggestion in the literature
that most patients benefit from
brief psychosexual interventions such
as counseling and support, the needs
of most patients are unmet.[10] Dr.
Carter and colleagues have touched
upon methods to meet those needs
within a sexual-health program. Such
a comprehensive approach should not
be limited to cervical cancer. Many
other malignancies, such as breast cancer
and hematologic malignancies,
interfere with sexuality and fertility.
In an ideal setting, trained professionals
interested in the preservation
of sexuality and fertility should evaluate
all new cancer patients, preferably
as part of tumor site groups or
teams in a cancer center. Patients identified
as being at risk would then be
offered assistance in whatever domain
required. Although the above services
could be offered off-site, the presence
of such expertise within the
cancer center has the advantage of
access to the treating physician and
the patient chart, including medical
history, therapy, and medications. Inclusion
of such a program within one of these facilities would truly justify
the use of the term "comprehensive
cancer center."
