How Tumor Markers Play a Crucial Role in Personalized Healthcare

Tumor markers hold significant importance within personalized medicine as it offers valuable insights regarding the presence of cancer [1]. By identifying specific biomarkers associated with tumors, healthcare providers can detect cancer at its earliest stages, often before symptoms emerge, leading to higher probabilities of successful interventions.

Advancing Colorectal Cancer Screening with Tumor Markers

One of the best-validated biomarkers is the use of fecal occult blood (FOB) testing in screening for colorectal cancer. According to the Cochrane Colorectal Cancer Group, 4 eligible randomized controlled trials show that screening participants over 50 years of age using the FOB testing method can significantly reduce mortality from colorectal cancer by 16% while there was a 25% increase in mortality for participants that failed to attend screening [5]. This underscores the importance of proactive participation in screening programs for early detection and improved outcomes.

Utilizing Tumor Markers to Improve Patient Quality of Life

Tumor markers are valuable tools in patient care planning as they provide minimally invasive and high sensitivity for detection. For example, in breast cancer, markers such as CA 15-3 and CA 27.29 have shown improved sensitivity and specificity compared to carcinoembryonic antigen (CEA), making them useful for monitoring treatment response in metastatic breast cancer patients [3]. In prostate cancer, the prostate-specific antigen (PSA) test combined with a physical exam can help identify individuals at risk and guide early detection efforts [3]. These markers offer a noninvasive approach that facilitates earlier diagnoses and improved treatment outcomes, which ultimately contributes to cost savings in terms of healthcare resources and patient quality of life.

Detecting Relapse and Monitoring Cancer Progression

Biomarkers can also play a significant role in detecting relapse during the follow-up period and identifying recurring cancers after initial treatment. They offer valuable insights into the human body, especially when there is no visible evidence of cancer [4]. Several specific tumor markers, such as prostate specific antigen for prostate cancer, human chorionic gonadotropin for gestational trophoblastic tumors and germ cell tumors of ovaries and testicles, and cancer 125 for epithelial ovarian cancer, prove to be beneficial in post-treatment scenarios [4]. Overall, with these markers, medical practitioners can monitor their patients’ progress and make informed decisions on relapse and cancer progression.

Challenges in Establishing Standard Values for Tumor Markers

Differences in sample collection, handling, storage, and profiling techniques across different research sites can introduce variations in the protein profile obtained from a particular sample [4]. Consequently, standardization becomes a crucial issue that needs to be tackled, encompassing factors such as biological variation, preanalytical variables, and analytical variability [4]. These challenges must be overcome to establish consistent and reliable standard values for tumor markers to ensure accurate interpretation and effective utilization in clinical settings.
