Cell-free DNA as a prognostic and predictive biomarker in resectable distal common bile duct cancer.
Background: Cell-free DNA (cfDNA) as an oncological biomarker has drawn much attention in recent years, but very limited effort has been made to investigate the prognostic values of cfDNA in distal common bile duct (CBD) cancer.
Methods: Plasma cfDNA was measured in 67 patients with resectable distal CBD cancer. Survival outcomes and the correlation of cfDNA with other conventional prognostic factors were determined.
Results: cfDNA levels were significantly higher in female patients, and those with poor tumor differentiation, abnormal serum carcinoembryonic antigen (CEA) level, and stage III cancer. The significant prognostic factors included a high cfDNA level (>8955 copies/mL), abnormal serum CEA level, stage III cancer, and positive resection margins. Compared with patients with high cfDNA level, those with lower cfDNA level (≤8955 copies/mL) had significantly better overall survival outcomes (74.4% vs 100% and 19.2% vs 52.6%, for 1- and 5-year survival rates, respectively, p = 0.001). The cfDNA level, perineural invasion, CEA level, and radicality were identified as independent prognostic factors for distal CBD cancer after multivariate analysis.
Conclusion: Circulating cfDNA levels play a significant role in predicting the prognosis and survival outcome for resectable distal CBD cancer. Furthermore, acting as a promising liquid biopsy, cfDNA could serve as a prognostic and predictive biomarker in combination with current conventional markers to improve diagnostic and prognostic efficacy.
期刊介绍：
Journal of the Chinese Medical Association, previously known as the Chinese Medical Journal (Taipei), has a long history of publishing scientific papers and has continuously made substantial contribution in the understanding and progress of a broad range of biomedical sciences. It is published monthly by Wolters Kluwer Health and indexed in Science Citation Index Expanded (SCIE), MEDLINE®, Index Medicus, EMBASE, CAB Abstracts, Sociedad Iberoamericana de Informacion Cientifica (SIIC) Data Bases, ScienceDirect, Scopus and Global Health.
JCMA is the official and open access journal of the Chinese Medical Association, Taipei, Taiwan, Republic of China and is an international forum for scholarly reports in medicine, surgery, dentistry and basic research in biomedical science. As a vehicle of communication and education among physicians and scientists, the journal is open to the use of diverse methodological approaches. Reports of professional practice will need to demonstrate academic robustness and scientific rigor. Outstanding scholars are invited to give their update reviews on the perspectives of the evidence-based science in the related research field. Article types accepted include review articles, original articles, case reports, brief communications and letters to the editor
