What is the cancer detection rate of brush biopsy?

The choice indicating a cancer detection rate of 20-60% for brush biopsy is aligned with the performance statistics typically reported for this diagnostic technique. Brush biopsy is a minimally invasive method used primarily for sampling cellular material, particularly in gastrointestinal and respiratory tract lesions. The cancer detection rate reflects its ability to find malignant cells within the sampled tissue.

Given its utility in assessing lesions that may not be easily accessible through other means, like traditional biopsy, the brush biopsy offers a reasonable detection rate within the 20-60% range. This range suggests that while it is not as definitive as some more invasive techniques, it still provides valuable clinical information that can lead to further investigations or treatments when positive results are found.

The selected range is also supported by various studies showing that brush biopsies can yield significant results, especially in the context of endoscopic procedures where visual access to suspected lesions is available, enhancing the likelihood of obtaining adequate samples for cytological analysis.
