Objectives By the end of this presentation, the observer should be able to…

• Recognize trends in cancer prevalence, mortality and survivorship.

• Identify common issues in cancer survivorship.

• Identify diet and physical activity guidelines for

cancer survivorship and outline the rationale that

supports them.

• List some of the gaps in knowledge related to

nutrition and cancer survivorship

• Identify reliable sources for nutrition and cancer

information.

WCRF- AICR (2007) American Cancer Society (2012)

Weight Be as lean as possible without

becoming underweight

Achieve & maintain a healthy weight

Physical

Activity (PA)

Regular PA, >30 min/day Avoid inactivity; PA >150/week;

strength training 2 x week

Dietary

Pattern

Avoid sugary drinks. Limit

energy-dense foods (foods high

in sugar & fat, and low in fiber)

Eat more of a variety of

vegetables, fruits, whole grains

and legumes

Limit consumption of

processed & red meat

Diet High F&V & Whole Grains

• Choose foods & beverages in

amounts that achieve & maintain a

healthy weight

• Eat > 2.5 cups fruits & vegetables/day

• Whole vs. refined grains

• Limit consumption of processed & red

meat

Other Limit salty foods -

Alcohol If drink limit to 1-2 drinks/day If drink limit to 1-2 drinks/day

Supplements Do not use supplements to

protect against cancer

Weight Management & Energy

Balance

Anorexia/Cachexia

• Patients with select respiratory,

G.I. & childhood cancers

• Patients living with advanced

cancer

• Increasing weight to desired

range important for recovery,

well-being, functional status

• Diet & exercise key roles +/-

pharmacotherapy

Overweight/Obesity

• Risk factors for several

cancers, as well as cancer-

related mortality

• Increased weight at diagnosis

is a poor prognostic factor

• Weight gain common during &

after treatment–linked with co-

morbidity, functional decline &

maybe recurrent/progressive

CA

Worldwide rates of obesity and overweight

• Worldwide 35% of adults are overweight and 11% are obese (2008)

doubled since 1980 – prevalence higher in select survivor groups

(breast & prostate)

• 65% of the world's population live in countries where overweight and

obesity kills more people than underweight.

• Medical costs for obese people are $1,429 (USD) higher than those

of normal weight

Nutrition & Physical Activity Guidelines for Cancer Survivors

Achieve and maintain a healthy weight

If overweight or obese, limit high calorie foods & beverages increase physical

activity to promote weight loss

Engage in regular physical activity

• Avoid inactivity; resume normal activities as soon as possible following dx

• Exercise >150 minutes/week

• Include strength training exercises at least 2 days/week

Achieve a dietary pattern that is high in vegetables, fruits and whole grains

• Follow ACS Guidelines on Nutrition & Physical Activity for Cancer Prevention

- Choose foods & beverages in amounts that achieve/maintain a healthy weight

- Limit processed and red meat

- Eat > 2.5 cups of vegetables & fruits/day

- Choose whole grains instead of refined grain products

- If you drink ETOH, drink <1 drink/day for ♀ & 2 drinks/day for ♂

Supplements

• Try to obtain nutrients through diet, first.

• Consider only if a nutrient deficiency is biochemically or clinically observed, or if

intakes fall persistently below recommended levels as assessed by an RD.

• Substitution estimates of 1 serving/day of other foods (e.g., fish, poultry, nuts,

legumes, low-fat dairy, and whole grains) for 1 serving/day of red meat were

associated with a 7% to 19% lower mortality risk. Estimates suggest that

9.3% of deaths in men and 7.6% in women could have been prevented at

follow-up if there was a reduction in 0.5 servings/day (~42 g/day) of red meat.

Alcohol

• Direct association with cancers of the kidney, head and neck and primary risk of breast cancer (“no amount of alcohol is safe”

• If you are a survivor of head and neck cancer you should not drink alcohol since it will increase your chance complication and reduce survival

• If you are a survivor of other cancers the choice is less clear – it may increase your risk of recurrence (breast cancer) but also decrease your risk of death due to cardiovascular disease

• SELECT trial shows higher risk of prostate cancer with vitamin E and higher risk of diabetes with selenium.

• Several meta-analyses show significantly higher mortality with vitamin E & b-carotene

Bottom Line on Supplements

Rely on Food as a Source of Nutrients But , if considering supplements

-Have dietitian analyze diet for deficiency

- Check blood levels of nutrients

- Consider lowest dosage & most complex preparation

- If currently on supplements wean off slowly.

• Early stage breast cancer survivors in Multi-ethnic Cohort (n=670) Compared with inactive survivors consuming poor-quality diets, survivors engaging in any physical activity and consuming better-quality diets had an 89% reduced risk of death from any cause HR: 0.11 (0.04-0.36) and a 91% reduced risk of death from breast cancer HR: 0.09 (0.01- 0.89). (George et al. 2011)

• In 1490 early stage breast cancer survivors a combination of 5+ daily servings of F&V + accumulating 540+ MET-min/w associated with a doubling of survival HR: 0.56 (0.31 - 0.98) (Pierce et al. 2007)

• In 2193 post-menopausal breast cancer survivors from Iowa Woman’s Health Study those who were most adherent vs. least adherent (6-8 vs. 0-4) to AICR/WCRF guidelines had a 33% lower mortality rate (Inoue-Choi et al. 2013)

• Optimal timing

• Specific content, sequencing

• Impact on array of outcomes

• Mechanisms of action

• Factors that moderate effect

characteristics, treatment, age,

co-morbidity, gender, etc.)

• Optimal delivery channel
