Background/Objectives: To assess the correct sampling rates and self-collection satisfaction levels among female residents aged 25 to 64 years during first-time HPV testing in the communities of Ho Chi Minh City. Methods: An observational study was conducted on self-collection for HPV testing in communities from January to December 2024. The study employed a probability proportional to size sampling method, involving self-collected sampling and post-collection direct interviews. Results: The data show that 99.9% [95% CI = 0.99–1] of 775 women successfully collected their own samples during a first-time HPV testing process. The self-collection satisfaction rate was 80.4% [95% CI = 0.77–0.83]. Conclusions: Self-collected sampling for HPV testing has a very high success rate in communities. Moreover, women who feel confident in self-collection tend to have higher satisfaction rates with this new method. Therefore, self-collection sampling should be widely adopted for early cervical cancer screenings to test for high-risk HPV. It is essential to provide careful instructions and mobilization to encourage women’s confidence in performing self-collections.

Objective: HPV infection is a major contributor to cervical cancer, a common type of cancer affecting Vietnamese women. To develop effective prevention strategies for cervical cancer, it is crucial to understand the prevalence of high-risk HPV infection in communities. The objectives of this study were to determine the prevalence and distribution of HPV types among female residents in Ho Chi Minh City. Methods: This cross-sectional study employed a self-collection method, involving 775 participants selected using a Probability Proportional to Size technique (PPS) between January and December 2024. Results: The study found that 7.5% [95% CI: 5.6– 9.3] of the 775 specimens tested positive for high-risk HPV infection, with HPV-16 accounting for 9.7%, HPV-18 for 3.2%, and other high-risk types for 87.1% (31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 và 68). Compared to similar studies many years ago in Vietnam, the prevalence of high-risk HPV infection has not changed much. However, among high-risk HPV infections, the ratio of types 16 and 18 has decreased dramatically. Conclusion: Findings from this investigation reveal that the high-risk HPV infection prevalence in Ho Chi Minh City communities is consistent with earlier research. Nevertheless, a significant change has been observed in the distribution of high-risk HPV genotypes. Specifically, the proportional representation of HPV types 16 and 18 within the high-risk HPV infection group has substantially diminished, now representing only approximately 30% of their prevalence a decade prior.

Đặt vấn đề: Tân sinh trong biểu mô cổ tử cung là các tổn thương tiền ung thư có thể phát hiện và điều trị hoàn toàn. LEEP là một trong những phương pháp điều trị tối ưu. Nguy cơ ung thư cổ tử cung ở phụ nữ sau LEEP cao hơn dân số chung. Theo dõi và phát hiện sớm tái phát bằng xét nghiệm HPV. Mục tiêu: Xác định tỉ lệ nhiễm HPV sau khoét chóp bằng vòng điện 12 tháng ở phụ nữ tân sinh trong biểu mô cổ tử cung độ II – III và khảo sát một số yếu tố liên quan đến tình trạng nhiễm. Đối tượng và phương pháp nghiên cứu: Nghiên cứu cắt ngang trên đối tượng phụ nữ đã điều trị bằng LEEP 12 tháng tại Đơn vị Kỹ thuật chẩn đoán khoa Khám Phụ khoa - Bệnh viện Từ Dũ từ tháng 1/2020 đến tháng 9/2020. Kết quả: Trong 148 trường hợp nghiên cứu, tỷ lệ nhiễm HPV là 11,48%, trong đó tỉ lệ nhiễm một hoặc nhiều type nguy cơ cao là 6,08%; tỷ lệ nhiễm HPV 16 là 4,05% và HPV 18/45 là 1,35%. Nhiễm HPV sau khoét chóp có liên quan đến bất thường tế bào học (PR = 3,55; KTC95%: 1,19 - 5,92; p = 0,003). Kết luận: Sau khoét chóp tỉ lệ nhiễm HPV còn khá cao, cần theo dõi đặc biệt trước khi chuyển về theo dõi thường quy. Background: Cervical intraepithelial neoplasia are pre-cancerous lesions that can be detected and prevented completely. LEEP is one of the optimal treatments. The risk of cervical cancer in women after LEEP is higher than that in the general population. Follow-up and early detection of recurrence should be done with HPV testing. Objective: Determination of HPV infection and risk factors after 12 months with LEEP treatment for cervical intraepithelial neoplasia grade II – III. Methods: The cross-sectional study was conducted at the Colposcopy department Tu Du Hospital from Jan. 2020 to Sep. 2020. Results: In 148 case studies, the percentage of HPV infection was 11.48%. More specifically, the other high risk HPV positive ratio was 6.08%; HPV 16 was 4.05% and HPV 18/45 was 1.35%. HPV infection after LEEP was significantly related to abnormal cytology (PR = 3.55; 95% confidence interval: 1.19 - 5.92; p = 0.003). Conclusion: Because of the high ratio of HPV infection after LEEP, women after treatment need specific management.
