Phẫu Thuật Ruột Kết ở Bệnh Nhân Hội Chứng Lynch: Khi Nào và Như Thế Nào?
Tóm tắt
Hội chứng Lynch là hội chứng dễ mắc ung thư đại trực tràng di truyền phổ biến nhất và chiếm khoảng 3% tổng số ca ung thư đại trực tràng. Đánh giá lâm sàng và lịch sử gia đình chi tiết là rất quan trọng trong việc xác định những bệnh nhân cần được đánh giá thêm thông qua tư vấn di truyền và xét nghiệm. Sự phát hiện các đột biến germline nguyên nhân tiềm tàng trong các gen sửa chữa lỗi DNA đã cho phép xác định chính xác hơn về nguy cơ ung thư đại trực tràng và ung thư ngoài đại trực tràng. Khi đã được chẩn đoán, việc giám sát tích cực qua nội soi đại tràng và các can thiệp kịp thời như cắt polyp làm giảm sự phát triển của ung thư đại trực tràng và tỷ lệ tử vong do căn bệnh này. Nếu ung thư đại trực tràng phát triển ở bệnh nhân hội chứng Lynch, phẫu thuật cắt bỏ mở rộng được khuyến nghị dựa trên nguy cơ ung thư đại trực tràng xảy ra thứ phát cao. Các cắt bỏ mở rộng có thể được thực hiện mà không làm giảm đáng kể chất lượng cuộc sống. Cần có sự nhận thức lâm sàng cao hơn để thúc đẩy việc chẩn đoán và quản lý phù hợp.
