The relationship of human papillomavirus and cytology co-testing results with endometrial and ovarian cancer diagnoses.

ABSTRACT:

Background

To investigate whether routine cervical screening using human papillomavirus (HPV) and cytology co-testing effectively identifies women with endometrial (EC) or ovarian (OvC) cancer.

Methods

In 2003, Kaiser Permanente Northern California implemented triennial co-testing in women aged ≥30 years. Index screening results (n = 2,385,729) were linked to subsequent EC (n = 3434) and OvC (n = 1113) diagnoses from January 1, 2003 to December 31, 2017. EC were categorized as type 1 or 2, and, selectively, EC and OvC diagnoses were stratified on whether symptoms were present at the time of the co-test. Fractions and absolute risks of EC or OvC of each co-testing result were calculated.

Results

Most EC (82.18%) and OvC (88.68%) were preceded by a negative HPV and negative cytology co-test. More EC were preceded by atypical squamous cells of undetermined significance (ASC-US) or more severe (ASC-US+) cytology and negative HPV test (n = 290) (8.44% of EC) compared to a negative cytology and a positive HPV test (n = 31) (0.89% of EC) (p < 0.001). The absolute risk of any EC diagnosis following ASC-US+ and negative HPV test was 0.48%. Atypical glandular cells (AGC) cytology and a negative HPV result preceded 6.92% of any EC diagnosis, with an absolute risk of 4.02%, but preceded only 1.13% of type 2 EC cases, with an absolute risk of 0.24%, in asymptomatic women. AGC cytology and a negative HPV result preceded 1.44% of OvC, with an absolute risk of 0.28%.

Conclusions

Abnormal cervical screening tests, even AGC cytology, rarely precedes and poorly predict women with EC or OvC.

Project description:ImportanceLittle is known about the long-term yield of high-grade cervical intraepithelial neoplasia (CIN) and the influence on biopsy and treatment rates of human papillomavirus (HPV) triage of cytology showing atypical squamous cells of undetermined significance (hereafter ASC-US cytology).ObjectiveTo examine 5-year outcomes after ASC-US cytology with vs without HPV testing.Design, setting, and participantsIn this observational study, all cervical cytology and HPV testing reports from January 1, 2007, to December 31, 2012, were obtained for women throughout New Mexico and linked to pathology reports. The dates of the analysis were May 4, 2015, to January 13, 2017.Main outcomes and measuresInfluence of HPV testing on disease yield, time to histologically confirmed disease, and biopsy or loop electrosurgical excision procedure rates.ResultsA total of 457 317 women (mean [SD] age, 39.8 [12.5] years) with a screening test were recorded between 2008 and 2012, and 20 677 (4.5%) of the first cytology results per woman were reported as ASC-US. CIN grade 3 or more severe (CIN3+) lesions were detected in 2.49% of women with HPV testing vs 2.15% of women without HPV testing (P = .23). Time to CIN3+ detection was much shorter in those with HPV testing vs those without testing (median, 103 vs 393 days; P < .001). CIN grade 1 was detected in 11.6% of women with HPV testing vs 6.6% without testing (relative risk, 1.76; 95% CI, 1.56-2.00; P < .001). Loop electrosurgical excision procedure rates within 5 years were 20.0% higher in those who underwent HPV testing, resulting in more CIN2+ and CIN3+ detection.Conclusions and relevanceHuman papillomavirus testing led to faster and more complete diagnosis of cervical disease, but 55.8% more biopsies and 20.0% more loop electrosurgical excision procedures were performed. In those tested, virtually all high-grade disease occurred in the 43.1% of women who were HPV positive, allowing clinical resources to be focused on women who need them most. These data provide essential information for cervical screening guidelines and public health policy.

Project description:The relationship between the vaginal microbiota, high-risk human papillomavirus infection, and abnormal cervical cytology has not been well characterized. Our objective was to characterize the vaginal microbiota in a stratified random sample of women from a population-based study in Appalachia. We analyzed a random sample of 308 women in the Community Access, Resources and Education: Project 3 study across 16 clinics in Ohio and West Virginia. Using Illumina MiSeq sequencing of 16S rRNA gene amplicons, we characterized the vaginal microbiota among (I) 109 women randomly chosen with abnormal cervical cytology (i.e., the majority were atypical squamous cells of undetermined significance (n=55) and low-grade squamous intraepithelial lesions (n=45) while n=6 were high-grade squamous intraepithelial lesions and n=3 were atypical glandular cells); (II) 110 high-risk human papillomavirus infection only without cytologic abnormality; and (III) 89 women from a stratified random sample without cytologic abnormalities (negative for intraepithelial lesion or malignancy or any human papillomavirus infection). Among the women with abnormal cervical cytology (n=109), 80 had human papillomavirus infection, the majority of which were positive for a high-risk type (n=61). Nearly all of the women were non-Hispanic White (94.5%), and the mean age was 26 (IQR=21-39) years. Women with abnormal cervical cytology or who were HPV+ were more likely to have a diverse vaginal microbiota characterized by higher Gardnerella vaginalis relative abundance, compared to women without cytologic abnormalities whose communities were more likely to be Lactobacillus spp. dominant (P<0.04). Women without cytologic abnormalities had a higher prevalence of L. iners dominated communities than women with abnormal cervical cytology and HR HPV+ respectively (P<0.04), and L. gasseri relative abundance was differentially greater among these women compared to women with abnormal cervical cytology or who were high-risk HPV+ (Linear discriminant analysis effect size =4.17; P=0.0009). After adjustment for age, white race, current smoking, and ≥2 male partners in the last year, however, we did not detect differences in the vaginal microbiota community states across the three outcome groups. Compared to women without cytologic abnormalities, the vaginal microbiota of women with abnormal cervical cytology or who were high-risk HPV+ were characterized by a diverse community with increased relative abundance of G. vaginalis and reduced relative abundance of L. gasseri. However, these differences were attenuated after adjustment for other factors. Further study and validation of these differences for prognostic use is warranted.
