Objectives





Incidence of cancer and survivorship among
Adolescent and Young Adult (AYA) population
Survivorship and significance of fertility
Effects of cancer and cancer treatment on
fertility
Assessment of fertility
Age appropriate fertility preservation options
– Standard and Experimental

Key considerations when discussing fertility with
patients and families
Cancer and Survivorship Among
Adolescent and Young Adults
Approximately 70,000 Adolescent and Young Adult (1539) and 10,000 children (<15) are diagnosed with
cancer each year
 Childhood cancer survivorship > 70%
 1 of 900 individuals in U.S. between 15-45 is a childhood
cancer survivor
 Approximately 270,000 cancer survivors originally
diagnosed less than 21 years of age are currently living
in the United States

Infertility
“Inability to conceive after 1 year of
intercourse without contraception”
 Azoospermia
– No measurable level of sperm in semen
– Obstructive vs. issue with spermatogenesis

Damage to oocyte, follicles or uterus
– Immediate menopause
– Premature menopause
Infertility and General Population

Statistics
– 6.1 million Americans
– In 2002, 7% of women infertile

Multi-factorial causes
– Men
– Women
– Both
 Sexually transmitted diseases
 Lifestyle factors – smoking, alcohol, obesity
American Society of Clinical
Oncology (ASCO) Guidelines




Panel reviewed literature spanning 1997 to 2005
Fertility preservation is of great importance
Lack of knowledge and comfort of health care team
Effects of infertility resulting from cancer treatment:
– Psychosocial and emotional distress
– Loss of masculinity or femininity
– Most survivors prefer to have biological children

Survivors as Parents
– Experience with illness can enrich their role
– High value on family closeness
2006 ASCO Guidelines
“Oncologists should address the possibility
of infertility with patients treated during
their reproductive years and should be
considered as early as possible in the
treatment planning”
Urban Legends and Caution
Males

Azoospermia is potentially for life, not short term

Can still get someone pregnant!
– Sperm production can return immediately or many
years after cancer treatments

Pubertal development does not equal fertility

Caution!
– Sexually transmitted diseases
Urban Legends and Caution
Females

A “period” does not define fertility
– Amenorrhea is not a definite sign of infertility
– Return of a period does not equal fertility

Cancer treatment can take years off of the
biological clock

Caution!
– STD’s

Assessment of Fertility
After Cancer Treatment
 Semen
analysis
 Blood Work
 FSH
 Inhibin B
Cancer and Infertility
Women
Cancer itself does not appear to affect
fertility in women.
 Cancer treatments pose spectrum of risk

 Immediate infertility
 Premature menopause
 Compromised ability to carry a pregnancy

Multifactoral process
 Drug type & dose
 Radiation location & dose
 Patient age & pubertal status
 Pre-treatment fertility
A Word About Prepubertal Females

Early age at time of cancer treatment has
a protective effect
– Younger age with larger number of oocytes
requiring more radiation to cause damage
– Less mitotic activity
Cancer and Infertility
Women
Surgery can impair ability to become
pregnant and/or carry pregnancy
 Radiation can damage uterus and increase
risk of miscarriage
 Advise survivors who have received pelvic
radiation should seek high-risk OB

Cancer and Infertility
Women
Damage to oocytes and follicles can lead
to immediate menopause or premature
menopause years after treatment.
 Menstruation does not equal fertility
 Treatment affect on stromal function and
ovarian blood vessels

Standard Female Reproductive
Options
Embryo freezing
 Radiation shielding of ovaries
 Ovarian transposition
 Radical trachelectomy
 Donor embryos
 Donor eggs
 Gestational surrogacy
 Adoption

Embryo Freezing
Eggs are harvested and undergo in vitro
fertilization. Embryos are frozen for later
implantation.
 Time requirement
 Cost: ~ $8,000-12,000 per cycle / $350/year
storage fees

– Donor sperm $200-$500 / vial
Success rate: 20-33%, babies born
 Special considerations: partner, donor sperm

Radiation Shielding of Ovaries
Shielding reduces scatter to reproductive
options
 Time requirement: non-issue
 Cost: included in cost of radiation
 Success rate: limited to selected radiation
fields
 Special considerations: No protection from
chemotherapy

Ovarian Transposition
Surgical repositioning of ovaries away
from radiation field
 Time requirement: Outpatient procedure
 Cost: Maybe covered by insurance
 Success rate: Approximately 50%
 Special considerations: Expertise required

Radical Trachelectomy
Surgical removal of the cervix with
preservation of uterus
 Time requirement: During treatment
 Cost: Included in treatment cost
 Success rate: No evidence of higher
recurrence rate
 Special considerations: Early stage cervical
cancer, limited centers

Standard Female Reproductive
Options

Donor embryos
– Not biologic child

Donor eggs
– Offers opportunity for biologic child for father

Gestational surrogacy
– Legal implications

Adoption
– Inaccessibility to cancer survivors
Experimental Options
Egg/oocyte freezing
 Ovarian tissue preservation
 GnRH

Experimental Options for Females
Oocyte cryopreservation





Process the same, sperm not needed
Oocytes are more sensitive to freeze/thaw
process and more prone to damage
Average 2% (range 1-5%) chance of pregnancy
per oocyte (3-4 times less than with embryo)
200+ live births to date
~$12,000/cycle
Experimental Options for Females
Ovarian Tissue cryopreservation
Laparoscopic procedure
 Benefits:

– Ovarian stimulation not performed
– Acquire hundreds of immature oocytes
– Less delay in commencement of cancer treatment


HOWEVER – not a location available in Texas!
Concerns
– Reimplantation increase risk of recurrence?

How to develop the immature oocytes?
 Autotransplantation - Orthotopic vs. heterotopic
 Xenotransplantation
Two live births reported (2005)
 ~$12,000 for procedure; storage and reimplantation with additional cost
 Retrieval of immature oocytes with in vitro maturation (5 y.o. youngest
reported)
 Post chemotherapy preservation possible; however, lower yield

Assessment of Fertility
Difficult to predict reproductive horizon post
treatment
 Regaining menses post treatment does not imply
intact fertility
 Risk of premature ovarian failure is real
 Current assessment is:

– Day 3 of cycle
 FSH
 LH
 Transvaginal ultrasound to assess antral follicle count
– AMH (anti-mullerian hormone): determine ovarian
reserve
Experimental Options for Females
GnRH agonist





Lupron – 1 month or 3 month injection
Creates a prepubertal state, suppressing ovulation
When to give?
– 2-3 weeks prior to chemotherapy to prevent breakthrough bleeding from
occurring during time of cytopenia.
– Give up to 2 doses or 6 months total – bone demineralization
What does the literature say?
– Potential risks in hormone sensitive tumors unknown
– Does not protect follicles from radiation
– Mixed review
 No benefit vs. Menses resuming with or without pregnancy achievement
– 98% vs. 40% resumption of menses 6 months post chemotherapy
 Do agree – decrease risks associated with menses during time of
cytopenia
 Window of opportunity
Cost - $500/month
