Attitude toward human papillomavirus self-sampling and associated factors among Thai women undergoing colposcopy

Objective

To compare attitudes toward self-sampling for human papillomavirus (HPV) testing before and after specimen collection in women undergoing colposcopy. The factors associated with the pre-sampling attitude were also studied.

Methods

This prospective study enrolled women with abnormal cervical cytology and/or positive high-risk HPV who attended colposcopy clinics at 10 cancer centers in Thailand between October 2021 and May 2022. Prior to colposcopy, the attitudes of the women toward self-sampling were surveyed through a questionnaire. Written and verbal instructions for self-sampling were provided before the process and subsequent colposcopy. The attitudes toward self-sampling were reassessed after the actual self-sampling. Factors associated with the attitudes were analyzed.

Results

A total of 499 women were included in this study. The mean age was 39.28±11.36 years. A total of 85.3% were premenopausal, and 98.8% had sexual experience. With the full score of 45, the attitude score after self-sampling was significantly higher than the attitude score before self-sampling (39.69±5.16 vs. 37.76±5.71; P<0.001). On univariate analysis, the factors associated with attitude before HPV self-sampling were age, menopause, sexual activity, education level, income, knowledge regarding HPV, and prior HSIL histology. The remaining significant factor on multivariate analysis was sexual activity within the past year (B=0.105, 95% CI, 0.014-2.870; P=0.048).

Conclusion

Attitudes toward self-sampling improved after the actual self-sampling process, as evidenced by higher attitude scores. Sexual activity was the only independent factor related to the attitude before self-sampling.

The Impact of Waiting Time-to-Surgery on Survival in Endometrial Cancer Patients

BACKGROUND

Endometrial cancer (EC) is the most common gynecological cancer in developed countries and a standard treatment of surgery should be performed as expediently as possible. Delay time to surgery and survival was debated. The aim of this investigation was to evaluate the effect of time-interval between diagnosis and surgery (TDS) in EC patients with regards to prognosis and mortality rates.

METHODS

This retrospective study was conducted between January 2009 and May 2021 at Bhumibol Adulyadej Hospital, Thailand. Subjects were EC cases who underwent primary surgery during the study period. Cases with partial treatment were disqualified from the study. Subjects who underwent surgery before and after 6 weeks were classified as early and delayed surgery groups. Baseline and clinical characteristics were collected and analyzed.

RESULTS

During the study period, 419 EC cases were recruited. The mean age of participants was 56.8 years. Two-thirds (338/491) of subjects were menopausal. Endometrioid histology (406/491) was the most common histology subtype. Five years disease free survival (DFS) of early and delayed surgery groups were comparable at a percentage of 82.5 and 83.0, respectively. Among advanced stage and non-endometrioid EC cases, the delayed surgery group had significantly shorter DFS than the early group. Advanced stage, high grade and positive lympho-vascular space invasion (LVSI) were independent factors for poor DFS. Predictive factors for mortality were advanced stage and tumor recurrence.

CONCLUSION

The TDS was not a prognostic factor for disease recurrence or overall mortality. Time to surgery equal to or more than 6 weeks gave worse prognosis for DFS among advanced stage or non-endometrioid histology EC.
