In patients diagnosed with cancer before age 15,
the 5-year survival rate improved from

--- an average annual change of 1.68%
Less well known is the remarkable
improvement in prolonging survival

Cancer Survivorship

U.S.: 12 million cancer survivors
• 3.5% population
• Impact on public health

Increases in cancer survival
• Earlier diagnosis (screening)
• More effective treatment
• Prevention of secondary disease
• Decreases in mortality from other causes

Essential Elements Of Survivorship Care
• Education of the cancer survivor, family, health care providers
– Care plan based on future health risks
– Promotion of healthy lifestyles
– Possible genetic predispositions for counseling
• Surveillance for cancer spread, recurrence, or second cancers and
for long-term adverse physical, psychosocial, socioeconomic effects
• Intervention to prevent or treat consequences of cancer or therapy
• Communication between specialists and primary care providers to
ensure that the survivor’s health needs are met
• Research focused on understanding, preventing, treating adverse
consequences of cancer or its therapy
• Patient advocacy to address problems related to employment,
insurance, and disability

What are the physical
costs of survivorship?
General Considerations
• Risk of late effects depends on the tissue and
age of patient at time of treatment
• Late effects are dose and modality specific
(e.g., surgery, radiation, chemotherapy)
• Combined modality therapy can have additive
risks
Tissues at Risk for Late Toxicity
• Bone/soft tissues
• Immune system
• Cardiovascular
• Nervous system
• Dental
• Neuropsychologic
• Endocrine
• Ophthalmologic
• Gastrointestinal

Know Your Cancer-Related Health Risks
Surgery for Solid Tumors
• After removal of one of paired organs, the
remaining organ usually maintains function:
–
–
–
–
Enucleation (removal of eye)
Nephrectomy (removal of kidney)
Oophorectomy (removal of ovary)
Orchiectomy (removal of testes)
• It’s important to take precautions to preserve
the health of the remaining organ
Know Your Cancer-Related Health Risks
Surgery for Solid Tumors
• Surgery to remove tumors of bones or soft

• These surgeries may also
cause chronic pain that
limits activity
• Examples include:
– Amputation
– Limb-sparing surgery

Lung scarring from radiation leads to
stiff lungs that restrict air flow during
breathing
Scarring from radiation can
affect heart rhythms, heart
muscle and valve function and
blood vessel flow

Radiation cause kidney
damage and bladder scarring
Some of the signs of radiation
injury of the urinary tract are:
• High blood pressure
• Blood in urine
• Incontinence
• Problems voiding

Health habits
Age at Treatment Matters…
• Learning problems after brain radiation
– Younger patients at higher risk compared
to older patients
• Infertility after alkylating chemotherapy
– Older females at highest risk compared to
younger females
Chemotherapy Dose Matters…
Heart muscle problems after anthracyclines
Risk
Anthracycline dose
Low
Less than 100 mg/m2
Medium
Between 100 and 300 mg/m2
High
More than 300 mg/m2
Combination of Treatments Matters…
• Chest radiation:
scarring of heart
lining, heart valves, or
blood vessels
• Anthracycline
chemotherapy:
weakening of the
heart muscle
Risk of heart problems is greater if
cancer treatments have similar risks
for health problems.
Health habits matter…
• Lung scarring can occur
after chest radiation and
bleomycin
• Stiff lungs restrict air flow
during breathing
• Thick scarred air sacs do
not release oxygen to the
tissues as well
• Smoking increases the
risk of lung injury
Genes & Family History Matter…
Cancer treatment may result in an earlier onset
of diseases that “run” in families, especially
those that usually present in adulthood
•
•
•
•
Heart disease
High cholesterol
High blood pressure
Diabetes
•
•

Important Facts About Late Effects
• The chances of having late effects after cancer is high
• The chance of having serious or life-threatening late
effects after modern cancer therapy is low
• Knowing your cancer history and possible health risks can
help you and your doctor
work together to prevent
late
effects or diagnose
health
problems early
• Regular check-ups are
needed to diagnose and
prevent late effects
What Doctors Can Do…
• Design cancer treatments to
reduce the risk of late effects
• Develop therapies to protect
normal tissues
• Monitor childhood cancer
patients for late effects
• Prescribe corrective therapy
What Survivors Can Do…
• Have regular check-ups so late
effects can be prevented or
detected in earlier stages
• Follow doctor’s advice about
medications and other interventions
that can reduce the risk of late
effects
• Practice health behaviors that
reduce the risk of late effects
Habits that affect risk
• Smoking
• Sun
exposure
• Diet
• Physical
activity
• Alcohol
intake
Tobacco Use
•
•
•
•
•
Don’t smoke. If you do smoke, QUIT!
Don’t use any tobacco products
Avoid smoke-filled rooms
Exercise regularly to keep your lungs fit

Preventing Skin Cancer
• Do not tan.
• When outdoors, stay
in the shade.
• Limit sun exposure
from 10-4.
• Practice sun
protection measures.
– Sunscreen
Apply frequently!
– Wide brim hat
– Long-sleeve shirt
– Sun glasses with UV
absorption
A Healthy Diet
• Eat a variety of healthful foods, with an
emphasis on plant sources
 Eat > 5 vegetables and fruits servings each day.
 Choose whole, rather than processed, grains
 Limit consumption of red meats
 Choose foods to maintain a healthful weight
• Check out:
Physical Activity and Weight
• Adopt a physically active lifestyle
 Moderate activity for > 30 minutes on > 5 days
 Moderate-to-vigorous activity for > 45 minutes on
> 5 days may further reduce breast and colon
cancer risks
 Balance caloric intake with physical activity
• Check out:
 http://www.cdc.gov/healthyweight/
 http://www.mypyramidtracker.gov/
Maintain a Healthy Weight
• Body mass index
Weight (kg) divided by
height (cm)2
• Normal weight = BMI 18.5-25
• Overweight = BMI 25-30
• Obese = BMI > 30
Check out: http://www.cdc.gov/healthyweight
Alcohol and Health
• Alcohol increases risk of cancer of the mouth,
throat, voice box, esophagus, liver, and
breast
• Alcohol may also increase the risk of colon
cancer
• Alcohol increases risk of liver injury in people
with chronic hepatitis and other liver disease
• Alcohol may have some benefit in preventing
cardiovascular disease
Guidelines for Alcohol Intake
• If you drink, limit
alcohol drinks to less
than two drinks a day
for men and one for
women
• A drink is defined as
12 ounces of beer, 5
ounces of wine, or
1.5 ounces of 80
proof distilled spirits
Just
remember,
only one
or two!

for lung cancer
• Thyroid function tests annually in pts after
neck/chest RT
Specific f/u recommendations for
Hodgkin Lymphoma part 2
• Vaccinations q 6 years in patients after
splenectomy
• Lipid screening q 1-3 years (LDL <100)
• CAD risk factor modification
• Women after chest RT treated at age <35 y:
– Yearly mammogram 8 years after RT or
age 40
– Consider breast MR
Specific f/u recommendations for
Hodgkin Lymphoma - part 3

consider visit with a cardiologist at 10 years
• Skin check annually
• Baseline vitamin D level
• Consider a screening colonoscopy prior to
age 50 if prior abdominal radiation
