HCC in HIV:
The price of hepatitis viral coinfection and cirrhosis
• Risk factor: Chronic liver disease.
– Chronic hepatitis viral infection: HCV, HBV.
– Alcohol use.
– Role of NASH?
• HCC disease burden in HIV/HCV-coinfected patients with cirrhosis:
– 2nd most frequent type of liver decompensation.

GWAS studies: SNPs associated with the risk of HCC
12/12/2014
6
• Methodological limitations of previous studies:
• Selection of inadequate control populations.
• Inclusion of heterogeneous cohorts of HCC (etiology, cirrhosis).
• Most studies conducted in Asian populations or HBV-related HCC.
• GWAS studies:
– Conflicting results and poorly replicated.
– Relevant factors as the presence of cirrhosis not controlled.
• Reported associations of SNPs may be linked to inflammation or
fibrosis progression and not specifically with HCC development.
• No available data in HIV-infected patients.

HCC in HIV-infected patients:
an emerging problem.
• France: HCC-related mortality has increased from 16% of liver-related
deaths in 2000 to 42% in 20101,2.
• US:
• The prevalence of HCC in the Veteran Affairs healthcare system has
increased from 0.07% to 1.6% between 1996-20093.
• Increasing incidence of HCC in HIV population, with an excess risk 4
times higher than general population4.
• Spain: The incidence of HCC has increased from 0.2 to 2.8 cases per
1000 person-years from 2000 to 20095.

• N= 82 HCC cases in HIV patients from 1999 to 2010 in 18 hospitals in Spain.
• The incidence of HCC increased by a factor of 14 from 2000 to 2009

• Still controversial:
• Some investigations have suggested that HIV shortens the time
from HCV infection to the development of HCC1-3.
• Other retrospective studies have not demonstrated that HIV
increases the risk of HCC4-5.
• Prospective studies assessing the incidence of HCC in individuals
with HCV-related cirrhosis with or without HIV are needed.

SVR is associated with a lower risk of ESLD, HCC
or death in HIV/HCV-coinfected patients
Limketkai BN.
JAMA 2012.
Cumulative survival free of ESLD, HCC or death
according to response to HCV treatment from baseline
…but waiting for F4 to achieve SVR
is too late to prevent HCC
• 166 HIV/HCV-coinfected patients with compensated cirrhosis who started peg-IFN + RBV.
• 43 (25%) achieved SVR. Median follow-up: 55 months
• SVR was associated with a lower risk of liver decompensation and overall mortality.

Merchante N.
AIDS 2014;28:41-7.
HIV/HCV-coinfected patients who achieved SVR
are still at risk of developing HCC
• n=167 HCC cases in HIV/HCV-coinfected patients in 26 hospitals in Spain.
• 13 (7.8%) cases were diagnosed in patients with previous SVR.
– Median (Q1-Q3) elapsed time from SVR to HCC diagnosis: 28 (20-39) months.
– Aggressive clinical course:
• US without nodules in the previous 6 months in 6 cases.
• Advanced stage (BCLC B-D) at diagnosis in most cases
• Median (Q1-Q3) survival: 3 (1-39) months.
• Genotype 3 more common than in non-SVR cases (83% vs 32%; p=0.001).
Surveillance of HCC with US should be maintained in HIV/HCV-coinfected
patients with cirrhosis who achieve SVR with anti-HCV therapy.
Concluding remarks
• The incidence of HCC has increased in the last decade in HIV-
infected patients, mainly driven by HCV-related cirrhosis.
• The clinical management of ESLD and HCC still needs to improve:
– Poor adherence to HCC surveillance with periodic US in cirrhotics.
– Late diagnosis of HCC in a high proportion of patients.
– Low rates of potential curative therapies and dramatically low survival.
• The erradication of HCV with antiviral therapy is the best approach
to prevent HCC, but:
– Starting therapy with F3/F4 fibrosis is too late to fully prevent HCC.
– HCC surveillance should be maintained in patients with cirrhosis in spite of
the consecution of SVR.
