Objective: The current study aimed to investigate the prognostic value of serological markers of hepatitis B virus (HBV) infection in squamous cell cervical cancer.
Methods: Squamous cell cervical cancer patients treated by concurrent chemoradiotherapy from January 2013 to December 2015 at Yunnan Cancer Hospital were retrospectively reviewed.
Results: Of a total of 277 patients, 12 (4.33%), 93 (33.57%), 2 (0.72%), 25 (9.02%), and 36 patients (13.00%) were seropositive for hepatitis B surface antigen (HBsAg), anti-hepatitis B surface antibodies (anti-HBs), hepatitis B envelope antigen (HBeAg), anti-hepatitis B envelope antibodies (anti-HBe), and anti-hepatitis B core antibodies (anti-HBc), respectively. No patients experienced more than mild hepatic adverse events during treatment. The five-year overall survival (OS) rates for patients with anti-HBs positive or negative status were 85.8% and 66.2% (p = 0.039), respectively. No statistically significant difference in the five-year OS rates was observed in HBsAg positive and negative, HBeAg positive and negative, anti-HBe positive and negative, anti-HBc positive and negative patients. The multivariable analysis revealed that anti-HBs positivity was an independent favorable prognostic factor for OS (HR= 0.279; 95%CI: 0.083-0.936; p = 0.039) in patients younger than 50 years.
Conclusions: The presence of anti-HBs predicts a superior OS for squamous cell cervical cancer patients aged younger than 50 years.
