HPV testing can lead to earlier detection and treatment of lesions, improving protection against cervical cancer.
A new study suggests that HPV testing for two high-risk strains (HPV16 and HPV18) detects more high-grade pre-cancerous lesions than current cervical cancer screening. The findings support the use of HPV testing as a primary screening tool to rule out disease, with cytology reserved for triage of women who test positive.
A new study reveals that nearly all high-grade noninvasive bladder cancer patients do not receive complete care as recommended by current guidelines. This suboptimal care has serious consequences, including increased risk of recurrence and progression to invasive tumors.
A study from Australia found a significant decrease in high-grade cervical abnormalities in girls aged 17 and younger following the introduction of an HPV vaccination programme. The incidence of high-grade abnormalities fell by 0.38% as compared to before the programme, with no decline seen for low-grade abnormalities or older age groups.
A study of 435 women who underwent treatment for precancerous cervical lesions found that a three-cytological-smears post-treatment surveillance strategy is effective in identifying women at long-term risk of cervical cancer. By adding high-risk human papillomavirus (hrHPV) testing, the need for subsequent screens can be reduced.
