Bladder cancer biomarkers: review and update

Area of Science:

• Oncology
• Biomarker Discovery
• Urological Cancer Research

Background:

• Bladder cancer exhibits high rates of recurrence and mortality, underscoring the need for improved diagnostic and prognostic tools.
• Current clinical management requires better methods for early detection, prognosis evaluation, and monitoring of therapeutic responses.

Purpose of the Study:

• To review existing literature on bladder cancer biomarkers.
• To identify potential DNA, RNA, and protein markers for clinical application.
• To highlight the need for developing sensitive and specific biomarker panels for early bladder cancer detection.

Main Methods:

• A comprehensive computerized literature search was conducted.
• Databases searched included Medline/PubMed.
• Keywords used were: bladder cancer, biomarker, early detection, prognosis, and drug response.

Main Results:

• Numerous potential bladder cancer biomarkers were identified at the DNA, RNA, and protein levels.
• These markers demonstrated varying degrees of sensitivity and specificity.
• A limited number of identified biomarkers have received clinical approval to date.

Conclusions:

• The development of effective bladder cancer biomarkers remains a critical research area.
• Future efforts should prioritize the identification of a panel of biomarkers with high sensitivity and specificity.
• Such panels are essential for the early detection of bladder cancer and improved patient management.
