Background and context: Translation of underlying individual genomic heterogeneity in cancer into precision medicine practice requires annotated cancer biorepositories. The potential for practice of precise medicine is also coupled to saving vital resources in low to middle–income countries. An overview of experience and outcomes from a tertiary level cancer center in a high-income country for liquid biobank established since 2009 is presented. Aim: To understand the challenges of building economically viable biorepositories that can be used for molecular diagnostics while delivering cancer care. Strategy/Tactics: An institutional ethics–approved prospective liquid biorepository was established in September of 2009 for advanced cancer patients. Informed consent–approved collection of 29.5 mL blood/urine was performed serially on enrolled patients and clinical annotation was obtained during follow-up including previous, current and future treatments and their outcomes. All specimens were processed using a uniform protocol in which extraction of germline DNA from buffy coats; serum for proteomics; platelet-poor and platelet-rich plasma (in citrate and EDTA anticoagulants) for microRNA and cell-free DNA extractions; and extraction of PAXgene RNA/DNA from whole blood was performed. Processing was done within 45 minutes of sample acquisition and storage in −80°C freezers with no freeze–thaw cycles. Program/Policy process: Biobanking for cancer care. Outcomes: Between September of 2009 and January of 2015, 535 advanced-stage prostate cancer patients in hormone-sensitive and castrate-resistant stage; 250 advanced kidney cancer patients; 110 testicular cancer patients were enrolled and 1550 collections were performed serially. This generated >60,000 plasma/serum/DNA/RNA aliquots. Nucleic acids (DNA/RNA) from buffy coats and whole blood of 500-1000 ng volume each were also extracted. Cell-free DNA for somatic mutational and copy number analysis; single nucleotide profiling from germline DNA; RNA expression profiling from whole blood and microRNA analysis in plasma has been performed from this cohort along with proteomics using tandem mass spectrometry. By 2017, this has resulted in >35 scientific publications; 5 patents; multiple national and international grant awards and enhanced precision cancer care for patient care. The cost burden for establishing the infrastructure was highly economical. What was learned: In our experience, liquid biopsy repositories can augment clinical cancer globally, but do not find this discussed in low to middle–income nations. Advancing and applying molecular oncology and team science to prospectively collected and retrospectively annotated biobanks can be a cost-efficient resource in a global cancer healthcare delivery system and a useful tool for scientific and economic opportunities and collaborations.

Background: Precision medicine puts forward customized healthcare for cancer patients. An important way to accomplish this task is to stratify patients into those who may respond to a treatment and those who may not. For this purpose, diagnostic and prognostic biomarkers have been pursued. Objective: This review focuses on novel approaches and concepts of exploring biomarker discovery under the circumstances that technologies are developed, and data are accumulated for precision medicine. Results: The traditional mechanism-driven functional biomarkers have the advantage of actionable insights, while data-driven computational biomarkers can fulfill more needs, especially with tremendous data on the molecules of different layers (e.g. genetic mutation, mRNA, protein etc.) which are accumulated based on a plenty of technologies. Besides, the technology-driven liquid biopsy biomarker is very promising to improve patients’ survival. The developments of biomarker discovery on these aspects are promoting the understanding of cancer, helping the stratification of patients and improving patients’ survival. Conclusion: Current developments on mechanisms-, data- and technology-driven biomarker discovery are achieving the aim of precision medicine and promoting the clinical application of biomarkers. Meanwhile, the complexity of cancer requires more effective biomarkers, which could be accomplished by a comprehensive integration of multiple types of biomarkers together with a deep understanding of cancer.
