Abstract

Aim

Cervical cancer is the third most commonly diagnosed cancer and the fourth leading cause of cancer deaths in women around the world. Human papilloma virus (HPV) infection is considered necessary factor for the development of cervical cancer and it is identified in 99.7% of cases. The main route of HPV transmission is sexual, and factors such as multiple partners and early onset of sexual activity favors infection and transmission. The incidence of cervical cancer in HIV-positive women is high and it is a defining disease of immunodeficiency syndrome (AIDS). These women also have more aggressive disease that is less responsive to the standard therapy. Viral hepatitis B and C, as well as HIV infection, are sexually transmitted diseases and they share similar risk factors to those of cervical cancer. In the case of hepatitis, they have great importance to public health because of their high prevalence, incidence and possible complications of acute and chronic forms. The objective of this study is to evaluate the prevalence of HIV, hepatitis B and C infection in patients with cervical cancer.

Methods

A retrospective search of the database at the Brazilian National Cancer Institute was performed, and all patients diagnosed with cervical cancer between October 2009 and December 2012 and the results of serological tests for HIV, hepatitis B and C infection were analyzed.

Results

A total of 1659 women were enrolled. Squamous cervical cancer was diagnosed in 78.6%, adenocarcinoma in 16.8% and less frequent histological subtypes in 4.6%. The median age for first sexual intercourse was 17 years. Number of sexual partners (median) was 3. Positivity for HIV infection was identified in 0.98% (12 patients in 1222 tested). Between patients tested for hepatitis B (n = 1342), positivity for anti-HBc-IgG was 13.85% (n = 186), indicating previous contact with hepatitis virus B. For hepatitis C, 2.18% (n = 31) of the group tested (n = 1422) had anti-HCV positive, and hepatitis C was identified in 15 cases by a confirmatory test.

Conclusions

Although the low prevalence of HIV infection, and hepatitis B and C in the cohort analyzed, the possibility of such co-infections should always be evaluated, since those diseases share routes of transmisson and prognosis could be influenced.
