Objective:
To investigate the efficacy and safety of targeting cancer metabolic vulnerabilities with specific anticancer agents.
Methods:
The systematic review and meta-analysis entailed search on PubMed, Embase and Google Scholar databases for cohort-based studies or clinical trials which reported hazard ratio for overall survival and/or median overall survival of patients treated with metabolicallyactive anticancer drugs. Data was analysed using the Number Cruncher Statistical System version 11.
Results:
There were 16 studies published between 1989 and 2018 that reported improvement in the overall survival (p=0.05) despite the reported significant heterogeneity across the studies (I2=70%). Exploiting amino acid metabolic vulnerabilities was associated with a favourable prognostic outcome (p=0.05), while targeting glycolysis and nucleic acid synthesis had no significant clinical importance (p>0.05).
Conclusions:
There is an urgent need to develop future therapies relying on the synergistic actions of nucleotide biosynthesis, glycolysis and amino acid metabolism.
Insights
Targeting cancer metabolic vulnerabilities with specific anticancer drugs shows promise, particularly by exploiting amino acid metabolism, leading to improved overall survival. Further research into synergistic therapies is crucial for enhanced cancer treatment outcomes.
Area of Science:
- Oncology
- Metabolic Pathways
- Drug Discovery
Background:
- Cancer cells exhibit unique metabolic vulnerabilities that can be targeted for therapeutic benefit.
- Understanding the role of specific metabolic pathways in cancer progression is key to developing novel anticancer agents.
Approach:
- A systematic review and meta-analysis of cohort studies and clinical trials were conducted.
- Searches were performed on PubMed, Embase, and Google Scholar for relevant literature.
- Data from 16 studies (1989-2018) were analyzed to assess the impact of metabolically active anticancer drugs on overall survival.
Key Points:
- Targeting cancer metabolism with specific agents demonstrated a significant improvement in overall survival (p=0.05).
- Exploiting amino acid metabolic vulnerabilities was associated with favorable prognostic outcomes (p=0.05).
- Targeting glycolysis and nucleic acid synthesis did not show significant clinical importance (p>0.05).
Conclusions:
- There is a critical need for developing novel cancer therapies that leverage the synergistic interactions of nucleotide biosynthesis, glycolysis, and amino acid metabolism.
- Future therapeutic strategies should focus on a multi-targeted metabolic approach for enhanced efficacy.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
