Factors Contributing to the Increase
in Cancer Cases in HIV
• 4-fold increase in HIV/AIDS population
• Greater and earlier start to smoking in HIV
• Rising proportion of HIV pts > 50 yo
• Cancer incidence increases with age
• Increase in some CA incidence rate among HIV
– Lung (3X), anal (29X), liver (3X), HL (11X)

NADC Incidence and Mortality
• Retrospective survey of Kaiser Permanente, N.
and S. California; 22,081 HIV+, 230,069 HIVmatched by age, sex, clinic and initial yr of F/U
• 5-yr survival for incident prostate, anal, lung,
colorectal cancers or Hodgkin lymphoma. All
cause mortality rates and mortality hazard ratios
• Earlier mean age at dx in HIV+ for anal, lung and
colorectal, but not for prostate or HL
• HIV+ dx at higher stage for lung and HL
• HIV+ reduced survival for HL, lung and prostate,
but not for anal and colorectal

Slide 15 of 31
Pathogenesis of NADC
• Many are virally-induced cancers, but not all
• Immune activation and decreased immune
surveillance
• HIV may activate cellular genes or protooncogenes or inhibit tumor suppressor genes
• HIV induces genetic instability (eg 6 fold higher
number of MA in HIV lung CA over non-HIV)1
• Increase susceptibility to effects of
carcinogens
• Endothelial abnormalities may allow for cancer
development
• Population differences based on genetics and
exposure to carcinogens

Aging Phenotype

• Increase CD4+ CD28- cells
• Shorten telomeres

• Increased CD56+ CD57+ cells
• See this in both HIV+ individuals and
elderly HIV- individuals

Screening Guidelines
• Cervical CA – begin within 3 yrs of 1st intercourse or 21
yo and q 1-2 yrs. If 30-70 and 3 normal Paps q3 yrs
• Prostate CA – discuss with MD at 50. DRE yearly and
individualized PSA testing
• Breast CA – clinical breast exam q 3 yr 20-30, yearly at
40, yearly mammogram start age 50
• Colon CA – flex sig q 5yrs or colon q 10 yrs and FOBT
yearly
• Others – periodic health exams after age 20, with health
counseling and oral, skin, lymph nodes, testes, ovaries
and thyroid exam
• Other tests based on family history, other known cancer
risk exposures or known risk factors

Slide 20 of 31
HIV Patient Screening
• Routine screening for HIV patients seems to be
done LESS frequently than age-appropriate
SOC screening for breast (67% vs 79%) and
colon (56% vs 77.8%) and prostate biopsies

• Concerns about higher false positive rate in HIV
(eg, NLST found reduction in lung cancer
mortality (20%) in older cigarette smokers) but
also high false positive rates, which may be
true in HIV as well
From RT Mitsuyasu, MD, at San Francisco, CA: March 29, 2013, IAS-USA.
Slide 21 of 31
Lung Cancer Screening
• CT imaging for early detection of lung
cancer is controversial (N Engl J Med. 2011
Aug 4;365(5):395-409), and HIV+ may be at
greater risk of developing lung cancer
• VA Aging Cohort substudy – prospective

Why is anogenital cancer important?
• Cervical cancer is the most common cancer
in women worldwide and anal cancer is as
common in MSM (75/100,000) as cervical
cancer in unscreened populations of women
(50-150/100,000 person-yr)
• Anal cancer particularly common in HIV+
MSM
• Anal cancer occurs in women as well
• Anal cancer is one of several cancers whose
incidence in the HAART era is increasing, not
decreasing

Screening for cervical and
anal dysplasia
• No national or international guideline for anal
screening other than NYS DOH anal Pap
screening guidelines, many recommend yearly
cervical and anal PAP, with colposcopy or
HRA and biopsy of any suspicious lesions and
q 6m F/U for those with abnormalities noted
• Many cervical cancer screen and treat
program now operating in resource-limited
settings

expected
•
•
•
•
•
•
•
Hepatitis B and HPV vaccination
Treat active Hepatitis C
Yearly cervical and anal (?) Paps – Gyn and HRA
Advise sun screen and avoid overexposure
Maintain high index of suspicion for cancer
Complete family history for malignancies
Breast, prostate and colon screening as per
guidelines for general population
• Treat all HIV patients with HAART
From RT Mitsuyasu, MD, at San Francisco, CA: March 29, 2013, IAS-USA.
Slide 31 of 31
Summary
• As HIV population ages with persistent immune
abnormalities, cancers will increase in number
• The risk of NADC is high with lung, anal, liver and
HL accounting for most of this increase. The risk of
colon, breast and prostate cancers are lower in HIV.
HL incidence is stable overall, but may reflect lack
of younger age peak, as all cases in HIV are EBV+
• As a minimum, we should conduct age/gender
appropriate screening for cancer. Counsel patients
on ways to reduce cancer risks
• Only through prospective clinical trials research
can prevention strategies be effectively evaluated
