Introduction:
Ginseng is associated to the reduction of the risk of liver-cancer and some time is used as adjuvant therapy to treat liver-cancer, but its outcome remains uncertain. Hence, the present study aimed to determine the association between Ginseng consumption and liver-cancer.
Methods:
By a systematic-literature search up to Decamber-2019, 9-studies included 13,766 subjects, 9235 Ginseng consumer. Odds ratio (OR) with 95% confidence intervals (CIs) was determined comparing Ginseng consumption and liver-cancer relationship using the dichotomous method with a fixed-effect or random-effect models.
Results:
Subjects consuming Ginseng had a significantly lower risk of developing liver-cancer than those not consuming Ginseng (OR, 0.46; 95% CI, 0.40-0.52, p < 0.001). Also, there was a significant relationship between Ginseng consumption as adjuvant-therapy and disease control rate (OR, 4.47; 95% CI, 2.41-8.28, p < 0.001), Karnofsky Performance Scale (OR, 4.31; 95% CI, 1.80-10.36, p = 0.001), response to chemotherapy rate (OR, 1.79; 95% CI, 1.05-3.02, p = 0.03) and decline of leukocyte count (OR, 0.17; 95% CI, 0.07-0.42, p < 0.001). However, there was no significant effect, but relatively favoring Ginseng consumption, between Ginseng consumption as adjuvant-therapy and one year survival rate (OR, 1.48; 95% CI, 0.78-2.81, p = 0.23), two year survival rate (OR, 1.69; 95% CI, 0.87-3.25, p = 0.12) gastrointestinal dysfunction (OR, 0.55; 95% CI, 0.17-1.79, p = 0.32), and the hepatic dysfunction (OR, 1.15; 95% CI, 0.59-2.22, p = 0.68).
Conclusions:
Ginseng may have an independent relationship with reducing liver-cancer incidence when administrated to healthy subjects as a supplement and with reducing cancer-chemotherapy related outcomes risk when administrated with chemotherapy as adjuvant therapy.
Insights
Ginseng consumption is linked to a lower risk of developing liver cancer. It may also improve outcomes when used alongside chemotherapy, reducing treatment-related side effects.
Area of Science:
- Integrative oncology
- Hepatology
- Cancer epidemiology
Background:
- Ginseng is traditionally used and investigated for its potential health benefits, including in cancer prevention and treatment.
- Previous studies suggest a possible association between ginseng consumption and reduced liver cancer risk, but outcomes as adjuvant therapy remain unclear.
Purpose of the Study:
- To systematically evaluate the association between ginseng consumption and the risk of developing liver cancer.
- To assess the efficacy of ginseng as an adjuvant therapy in managing liver cancer and its treatment-related side effects.
Main Methods:
- A systematic literature search was conducted up to December 2019, including 9 studies with 13,766 participants.
- Meta-analysis using odds ratios (OR) and 95% confidence intervals (CIs) was performed to compare ginseng consumption with liver cancer risk and adjuvant therapy outcomes.
Main Results:
- Ginseng consumers showed a significantly lower risk of liver cancer (OR, 0.46; 95% CI, 0.40-0.52).
- As adjuvant therapy, ginseng was associated with improved disease control rate (OR, 4.47), Karnofsky Performance Scale (OR, 4.31), chemotherapy response (OR, 1.79), and reduced leukocyte decline (OR, 0.17).
- No significant effects were observed for survival rates or gastrointestinal/hepatic dysfunction, though trends favored ginseng.
Conclusions:
- Ginseng may independently reduce liver cancer incidence in healthy individuals when used as a supplement.
- Ginseng as adjuvant therapy may mitigate risks associated with cancer chemotherapy, improving certain treatment outcomes.
