2004 REPORT of the SURGEON GENERAL:

HEALTH CONSEQUENCES OF SMOKING

Smoking harms nearly every organ of the body, causing many diseases and reducing the health of smokers in general.

Quitting smoking has immediate as well as long-term benefits, reducing risks for diseases caused by smoking and improving health in general.

Smoking cigarettes with lower machine-measured yields of tar and nicotine provides no clear benefit to health.

The list of diseases caused by smoking has been expanded.

TOBACCO USE and the DEVELOPMENT of CANCER: SUMMARY

 Tobacco products cause a variety of cancers

 Carcinogens present in tobacco products are responsible for these cancers

 Carcinogenesis likely involves a multistep process:

 Formation of DNA adducts

 Permanent cellular mutations

 Unregulated cellular growth

TOBACCO USE and the

TREATMENT of CANCER

(22)

A large proportion of patients are current or former smokers at the time of cancer diagnosis

Prevalence of ever smoking is highest among patients with tobacco-related cancers

90% -- lung cancer

80% -- head and neck cancer

20–50% of patients with cancer continue to smoke after diagnosis

A large proportion of patients who quit smoking will relapse after completing their treatment

EFFECTS of SMOKING on

CANCER THERAPY: SURGERY

 Smoking is associated with poor surgical outcomes

Respiratory complications during anesthesia

Cardiopulmonary complications

Infections and impaired wound healing

Cerebrovascular complications

Increased post-operative intensive care admissions

 Cessation interventions before surgery can reduce risk of complications

Best when offered at least 6 weeks prior to surgery

(26)

EFFECTS of SMOKING on

CANCER THERAPY: RADIATION

 Smoking reduces treatment efficacy

 Patients who smoke experience increased incidence of complications

Toxicity

Side effects

Overall morbidity

 Smoking is associated with reduced survival

rates

(27)

EFFECTS of SMOKING on CANCER THERAPY: CHEMOTHERAPY

Smoking may decrease the therapeutic effects of chemotherapy and other medications

Drug interactions with smoking -- increased hepatic metabolism (e.g., irinotecan, erlotinib)

More research is needed to delineate effects of smoking on chemotherapy outcomes

What is nicotine’s effects on cancer cells, and how does it impact treatment?

Does the lack of smoking data in patient charts impact our ability to understand the relationship between smoking and outcomes?

How does smokers’ increased risk of co- morbid disease impact their likelihood for entry into clinical trials?

HANDOUT

(28)

EFFECTS of SMOKING on

SECOND PRIMARY TUMORS

Continued smoking after diagnosis increases risk for second primary tumors -- this applies to:

The initial tumor site and other sites

Malignancies related to smoking

Malignancies not related to smoking

Dose-response relationship of intense cigarette use increases the risk for second primary tumors

Continued exposure to tobacco after cancer diagnosis

may be the more important risk factor

(29)

EFFECTS of SMOKING on

CANCER SURVIVAL OUTCOMES

 Survival is reduced in patients who smoke

As a direct result of malignancy

As a consequence of other smoking-related disease(s)

 Smoking history

>30 pack-years has been shown to be an independent

prognostic factor for both short- and long-term survival rates

 Tobacco mutagenicity may play a role in the growth and extension of certain cancers

Presents further obstacles for survival

Quitting smoking before diagnosis and treatment

can positively influence survival.

(30)

 Smoking after diagnosis negatively impacts

 Overall quality of life (QOL)

 Risk for co-morbid diseases, which

independently have a negative impact on QOL

 Symptom distress

Higher in persistent smokers, compared to never smokers

EFFECTS of SMOKING on QUALITY

OF LIFE in PATIENTS WITH CANCER

(31)

HOW DOES SMOKING CESSATION IMPROVE CANCER PROGNOSIS?

 Quitting prior to diagnosis and treatment has a positive influence on prognosis and survival

 Examples

 Head and neck cancer

Quitting 12 weeks and 1 yr prior to diagnosis reduces mortality by 40% and 70%, respectively

 Non-small cell lung cancer

Quitting at any point prior to lung operation is beneficial to

prognosis and long-term survival

(32)

WHAT FACTORS POSITIVELY INFLUENCE QUITTING in PATIENTS WITH CANCER?

 Patient awareness of the link between smoking and their

diagnosed smoking-related cancer

 Patient concern about recurrent disease and the effects of smoking on treatment success

 Advice given in the context of

medical care

(33)

MORE INTENSIVE or TAILORED INTERVENTIONS MAY BE NEEDED

Patients with cancer tend to have:

Higher levels of nicotine dependence

Higher levels of psychiatric co-morbidity

Higher need for treatment support

High percentage of household smokers

Poorer general health and physical functioning

More stress and emotional distress

Cancer disease-related issues need to be taken into account in treatment decisions and patient monitoring

Impact of smoking on surgery, radiation, and chemotherapy

Systematic advice (from multiple providers), with stepped-care

approach for patients experiencing difficulty with quitting

(34)

RELAPSE in

PATIENTS WITH CANCER

Up to one third or one half of patients will either

continue to smoke after diagnosis or relapse after an initial quit attempt

Relapse is often delayed in patients with cancer, compared to healthy patients

Follow-up and monitoring is needed

In relapsers:

Encourage a subsequent quit attempt, to avoid additional

post-diagnosis risk due to smoking

(35)

SUMMARY: REASONS TO QUIT for PATIENTS WITH CANCER

 Reduced risk for complications related to cancer therapy and surgery

 Improved survival

 Improved quality of life

 Reduced risk of second primary tumor(s)

TOBACCO CESSATION is an essential

component of treatment for patients with cancer.

Fewer than 5% of people who quit without assistance are successful in quitting for more than a year.

Many patients under-estimate the impact that counseling can have on their ability to quit

Few patients adequately PREPARE and PLAN for their quit attempt.

Many patients assume they can just “make themselves quit” when they are ready to do so.

for tobacco use and dependence.

CANCER DIAGNOSIS:

A TEACHABLE MOMENT

“The window of opportunity remains open throughout treatment and into the period of cancer survivorship.”

-- Ellen R. Gritz, PhD

The University of Texas MD Anderson Cancer Center

 Interest and motivation to quit is increased after cancer diagnosis

Particularly for cancers closely related to smoking, such as lung and head & neck cancer

 Health-care providers should routinely address

smoking with patients and family members during

this window of opportunity

(81)

 Tobacco users expect to be encouraged to quit by health professionals.

 Screening for tobacco use and providing tobacco cessation counseling are positively

associated with patient satisfaction (Barzilai et al., 2001).

Barzilai et al. (2001). Prev Med 33:595–599.

Failure to address tobacco use tacitly implies that quitting is not important.
