HPV
An oncologists perspective
What is an adult oncologist doing
here?
The national burden of HPV related
cancers
• 33,000 cases cancer annually in sites where
HPV found
12,000 Head and Neck—72% HPV related,
projected to be 91% by 2025
12,000 Cervical– 91% HPV related
4000 Anal– 91% HPV related
4000 Vulvar/vaginal– 72% HPV related
1000 Penile– 65% HPV related
The worldwide burden of HPV related
cancers
• 500,000 cases of cervical cancer
• 273,000 deaths due to cervical cancer
annually
• 21,000 cases vulvar/vaginal cancer
• 11,000 cases of penile cancer
• 25,000 cases of anal cancer
• 22,000 cases of head and neck cancer
HPV infection: the trojan horse
• >80% of HPV infections cleared
• Chronic cervical infection leads to dysplasia
• 37% of cervical cancers occur in women aged 2038
• Latency
15-20 years with normal immune system
5-10 years in immunosuppressed
Similar latencies suspected for other sites of HPV
carcinogenesis
HPV Cancer trends 1
• Rising rates of all HPV related cancers
• Estimated that by 2020, HPV related head and
neck cancers will surpass HPV related cervical
cancers
• Anal cancer rates have increased 160% in
men, 80% in women in the past 30 years
HPV cancer trends
• Most related to highly oncogenic HPV type 16
and 18
• Cervarix protects against these
• Gardisil protects against HPV 6, 11, 16, 18
• Gardisil 9 protects against these AND 31, 33,
45, 52, 58
National efforts
“The President's Cancer Panel finds underuse of HPV vaccines
a serious, but correctable threat to progress against cancer.”

Why are adolescents and their parents embracing meningococcal and Tdap
vaccines but not the HPV vaccine? One possible explanation is a clash between
perception and reality, People just don’t understand how serious an infection HPV
can be. In a typical year in the United States about 150 people die from
meningococcus, four from tetanus, none from diphtheria, 20 from pertussis, and
roughly 4,000 from cancers caused by HPV. People are more than 20 times more
likely to die from HPV than from the other four diseases combined.
About 79 million people in the United States have been infected with HPV, and 14
million new infections occur every year. As a consequence, 18,000 women and
8,000 men suffer preventable cancers of the cervix, anus, penis and throat; it’s the
most common, and except for H.I.V., the most fatalsexually transmitted disease.
Another common misperception is that the HPV vaccine is ineffective and
immunity is short-lived. But the truth is that the HPV vaccine is virtually 100
percent effective at preventing the precancerous lesions caused by the types of
HPV contained in the vaccine, which would most likely prevent most cervical
cancers. Regarding how long immunity will last, the HPV vaccine is made in the
same manner as the hepatitis B vaccine, for which immunity lasts at least 30
years. Immunity provided by the HPV vaccine is likely to be no different.
Prevention, an oncologists fantasy!
• HPV infection is preventable but not treatable
• Few visible stigmata of infection with the
carcinogenic varieties
• Condoms only protect against 70% of
infections
• HPV vaccination enhances protection, best
when started early
• Early evidence that even one vaccine can
confer protection

population health

Adopt as flagship cause as Idaho ACP Governor
Idaho Medical Association Resolution passed July 2013
RESOLVED That the Idaho Medical Association adopt policy in support of the Centers for
Disease Control and Prevention guidelines on genital human papillomavirus vaccination (HPV), and
provide information to Idaho Medical Association physicians regarding access to HPV vaccinations for
their patients of both sexes at all income levels regardless of insurance coverage status.

New Ideas: spread the burden, spread
the risk, not the virus
• Recruit the kids themselves with school or
afterschool activities
– Melanie and colleagues: YWCA, Boy and Girl Scouts,
PSAs at kids movies.
• Recruit dentists, orthodontists, and hygienists
– They interact with childrens’ mouths and childrens’
parents. Obvious nonsexual way to introduce HPV
protection.
• Provide educational material to dental offices,
kids libraries, the public pool, etc.
Moving forward
• The goal is to increase statewide immunization
of both boys and girls before sexual debut.
• How do we give providers the extra time needed
to talk to parents?
• How do we overcome sexual fears? Vaccinate
before you date
• Everyone eventually wants grandkids-- Focus on
“not if, but when”.
• REBRANDING – not Gardasil, the HPV vaccine but
Gardasil, the anticancer vaccine
Parting thoughts
• Sexual contact is not necessary
• Kissing and skin to skin contact is enough
• We vaccinate against tetanus even though we
don’t expect our kids to step on a rusty nail. Why
wouldn’t parents want to take all action possible
to prevent infection and subsequent cancer in
their kids
• We need to recruit dentists, phys ed teachers,
coaches, in the fight against HPV related cancers.
