Slides from each case were reviewed and cases with sufficient neoplastic tissue were selected for molecular analysis. DNA was extracted from paraffin-embedded tissue samples for polymerase chain reaction analysis to detect HPV DNA sequences. Demographic and clinical data of each patient were retrieved from corresponding clinical records.RESULTS: HPV was detected in 15 (25%) of ESCCs. HPV-16 was the most frequently observed genotype, followed by HPV-18; HPV-59 was also detected in one case. Unfortunately, HPV genotype could not be established in three cases due to lack of material for direct sequencing, although universal primers detected the presence of HPV generic sequences. No low-risk HPV genotypes were found nor was HPV-16/18 co-infection. HPV presence in ESCC was not significantly associated with gender, age, alcohol consumption, smoking, anatomic location, or histologic grade. All patients belonged to low and very low socioeconomic strata, and were diagnosed at advanced disease stage. Male patients were most commonly affected and the male:female ratio in HPV-positive ESCC increased two- fold in comparison with HPV-negative cases (6.5:1 vs 3.1:1).CONCLUSION: High prevalence of high-risk HPV in ESCC in Mexico does not support the hypothesis that HPV-associated ESCC is more common in areas with higher ESCC incidence rates.展开更多

METHODS: HPV infection is considered to be a neces-sary condition for cervical cancer development. The study population included 1291 women, aged 25-55 years, attending cervical cancer screening. All women had a Papanicolaou(Pap) test, with liquid-based cytology(Thinprep), an HPV-DNA test and an evaluation of smoking habits. The COBAS 4800 system was used for HPV-DNA testing, enabling identifi cation of the following high-risk HPV(hr HPV)-types: each of HPVs 16 and 18 separately, and HPVs 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68 as a cocktail. The evaluation of smoking habits was assessed using the smoking intensity index(SII), a variable formed as the product of cigarettes consumed per day by the days(years × 365) that a woman was a smoker, divided by 1000. RESULTS: There were 136 smokers among 238 women tested positive for hr HPV-types(HPVs 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and/or 68), and 463 smokers among 1053 hr HPV-negative women(OR = 1.7, P < 0.001). This association was attributed to the youngest age group of women, aged 25-34 years(OR = 2.3, P < 0.001), while there was no association in other age groups. The intensity of smoking(increasing SII) showed no statistically signifi cant association with hr HPV infection. Cervical infection with HPV 16 and/or HPV 18 was also not associated with age or smoking habits. Finally, no association was found between Pap test status and smoking habits or smoking intensity. CONCLUSION: Smoking appears to be associated with hr HPV infection of the uterine cervix, particularly in younger women. Further studies should investigate whether this association is based on causality and evaluate the role of other possible co-factors.展开更多
