Tóm tắt
Mục tiêu: Tìm hiểu mối liên quan giữa Bacteroides fragilis (B. fragilis) với ung thư đại trực tràng (UTĐTT). Đối tượng và phương pháp: Nghiên cứu mô tả cắt ngang 192 bệnh nhân được chẩn đoán polyp hoặc UTĐTT các giai đoạn, điều trị tại Bệnh viện Trung ương Quân đội 108 từ tháng 5/2017 đến tháng 12/2020. Tỷ lệ nhiễm và tải lượng tương đối của B. fragilis được xác định tại mô đại tràng theo các giai đoạn bệnh bằng xét nghiệm realtime PCR. Kết quả: Trong 192 bệnh nhân polyp hoặc UTĐTT, tỷ lệ nhiễm B. fragilis tại mẫu mô đại tràng ở nhóm ung thư (71,2%) cao hơn nhóm polyp (34%) (p<0,05). Tải lượng tương đối B. fragilis ở nhóm ung thư (0,09 ± 0,27) cao hơn 9 lần so với nhóm polyp (0,01 ± 0,03), mô ung thư cao hơn mô lành ở nhóm ung thư giai đoạn II và III (p<0,05). Bệnh nhân ung thư đại trực tràng có nguy cơ nhiễm B. fragilis cao gấp 5 lần (CI 95%: 1,7-14,1, p=0,003) so với nhóm polyp lành tính. Kết luận: Nhiễm B. fragilis có thể liên quan đến UTĐTT.
