Who are the Cancer Survivors?
• More than 1 in 3 Americans will be
diagnosed with cancer in their lifetime
• 15.5 million Americans have a personal
history of cancer; >4% of the US
population
• More than 28 million survivors worldwide

Cancer Survivorship Facts
• Prevalence will increase sharply during the next
25 years with aging of the population
• 60% of survivors are over the age of 65
• Breast, Prostate, and Colorectal are the 3 most
prevalent cancer sites
• Approximately 14% of survivors were diagnosed
20 years ago

Definition of a Cancer Survivor
“From time of diagnosis, through the balance of his
or her life”
– NCCN
“Anyone with a history of cancer, from the time of
diagnosis and for the remainder of life, whether that
is days or decades.”
– National Coalition for Cancer Survivorship

What Has Led to our Success?
• Earlier detection
• Novel treatments
• Combined modality therapy
• Prolonged adjuvant and/or maintenance
therapies
• Prevention of second malignancies

The Effects of Cancer and Its
Treatment
• Physical and/or psychosocial Effects
• Long-term effects
• Late effects
• Range in severity
• Some improve over time, while others
progress or become permanent

IOM Findings: Survivorship Care
• Survivorship care is a
neglected phase of the
cancer care trajectory
• Recurrence, second cancers,
and treatment late effects
concern survivors
• Few guidelines on follow-up
care
• Providers lack education and
training
![Page 14: Breast Cancer Survivorship - Columbia Surgery · Tumor Marker Surveillance after Breast Cancer • No RCT data to support use of tumor markers for breast cancer monitoring (CEA, CA](https://reader030.vdocuments.site/reader030/viewer/2022041103/5f0252777e708231d403b27a/html5/thumbnails/14.jpg)
IOM Findings: Survivorship Care
• Survivors may:
• Be unaware of risk
• Have no plan for follow-up
• Opportunities to intervene
may be missed
• Care is often not coordinated
• Models of survivorship care
not tested
![Page 15: Breast Cancer Survivorship - Columbia Surgery · Tumor Marker Surveillance after Breast Cancer • No RCT data to support use of tumor markers for breast cancer monitoring (CEA, CA](https://reader030.vdocuments.site/reader030/viewer/2022041103/5f0252777e708231d403b27a/html5/thumbnails/15.jpg)
Why is Cancer Different from other
Chronic Diseases?
Cancer treatment is…
Complex
Multi-modal
Multi-disciplinary
Toxic
Expensive
Often poorly coordinated
Cancer treatment usually occurs in isolation from
primary health care delivery
![Page 16: Breast Cancer Survivorship - Columbia Surgery · Tumor Marker Surveillance after Breast Cancer • No RCT data to support use of tumor markers for breast cancer monitoring (CEA, CA](https://reader030.vdocuments.site/reader030/viewer/2022041103/5f0252777e708231d403b27a/html5/thumbnails/16.jpg)
Other Challenges
• Limited systematic study of the late effects of
cancer therapy
• Follow-up care plans have been ad hoc, with
focus on surveillance for recurrence
• When should health promotion and chronic
disease prevention become the focus?
• Infertility?
![Page 17: Breast Cancer Survivorship - Columbia Surgery · Tumor Marker Surveillance after Breast Cancer • No RCT data to support use of tumor markers for breast cancer monitoring (CEA, CA](https://reader030.vdocuments.site/reader030/viewer/2022041103/5f0252777e708231d403b27a/html5/thumbnails/17.jpg)
What is Needed to Implement the
Survivorship Care Plan?
• Acceptance of cancer as a chronic disease – following
an initial period of extraordinarily complex therapy
• Staff support for time required to prepare and
communicate the plan
• Expand the evidence-base of knowledge re: late
effects, follow-up needs, and survivorship care
• Train all health professions in the needs of the
growing number of cancer survivors – how to act on
the care plan recommendations

Breast Cancer as a Model for Study of
Late & Long-term Effects
• Most common cancer in women
• Occurs across the lifespan
• Complex treatments, high rates of cure
• Treatment affects menopausal status and
endocrine milieu of the woman
• Potential for substantial impact on physical and
emotional health

Surveillance Testing after Breast Cancer
• Breast cancer adjuvant clinical trials abandoned routine
monitoring with chest, liver, and bone imaging in the
1990s – recurrence detection rare before clinical
symptoms
• Two randomized trials conducted in the 1990s did not find
a difference in survival outcomes in women who had
routine clinical visits and mammograms compared to
women with more intensive surveillance including blood
work, chest films, scans, and ultrasounds

Tumor Marker Surveillance after
Breast Cancer
• No RCT data to support use of tumor markers for breast
cancer monitoring (CEA, CA 15-3, CA 27.29) for effect on
survival outcome, i.e. that detection of recurrence earlier
makes a difference
• The rate of false negative or false findings for these
markers are not known
• Normal or abnormal tumor marker results can contribute
to false reassurance and/or increased anxiety for patients,
as well as unnecessary medical evaluations

Common Survivorship Care Concerns
• Pain
• Fatigue
• Depression
• Physical limitations
• Cognitive changes
• Lymphedema
• Sexual dysfunction
• Menopause related symptoms
• Body Image / Weight Gain
• Secondary cancers
• Late effects of therapy
• Osteoporosis, cardiac, infertility

Cancer-related Fatigue
• Most common side effect of cancer and its treatment
• Occurs in 60-96% of patients during treatment (Wagner &
Cella, 2004)
• Fatigue may persist for months or years after successful
treatment completion
• 30% of breast cancer survivors report fatigue 1-5 years
post-diagnosis (Bower et al.;2000)
• 63% of fatigued survivors continue to report fatigue 5-10
years post-diagnosis (Bower et al., 2006)
![Page 27: Breast Cancer Survivorship - Columbia Surgery · Tumor Marker Surveillance after Breast Cancer • No RCT data to support use of tumor markers for breast cancer monitoring (CEA, CA](https://reader030.vdocuments.site/reader030/viewer/2022041103/5f0252777e708231d403b27a/html5/thumbnails/27.jpg)
Cancer-related Fatigue
• Different than “normal” fatigue due to lack of sleep or over-
exertion
• More pervasive, debilitating, longer-lasting
• Involves physical, mental, and emotional components
• Not relieved by adequate sleep or rest
• Fatigue occurs across different types of cancer and different
types of cancer treatment
• Mechanisms underlying cancer-related fatigue have not
been determined

Cognitive Complaints
• Self-reported complaints don’t always match performance
on neurophysiological (NP) testing
• Tests of memory, attention, reasoning, visual-spatial abilities
• Some studies document impairment on NP tests in cancer
patients that pre-exist cancer treatment
• 20-30% of breast cancer patients
• Biology of cancer (e.g. inflammation related)?
• Common risk factors for both cancer and cognitive impairment (e.g.
poor DNA repair mechanisms?)
• True incidence of cognitive decline is uncertain
• Estimates range from 15-25%; some percentages as high as 61%

Lifestyle Modifications & Br CA Prognosis
• Observational studies suggest:
• Higher physical activity may improve survival
• High fruit/veg and low fat diet may improve
survival
• Higher BMI is associated with poorer outcomes
• Clinical trials suggest:
• High fruit/veg and low fat diet may improve
survival in ER- Br CA (WINS)
• Potential mechanisms include insulin-IGF-1 axis,
inflammatory pathways, and hormonal pathways
