Abstract

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.

Effect of Hepatic Disease on Pharmacokinetics: Dose Adjustments Due to Hepatic Impairment

Hepatic impairment, characterized by decreased liver function, does not uniformly mandate adjustments in drug dosage. Whether dosage modifications are necessary depends on various factors related to the drug's metabolism and elimination pathways. If a drug is primarily excreted via the kidneys and bypasses significant hepatic processing, if it undergoes minimal metabolic transformation in the liver, or if it is volatile and primarily expelled through the lungs, dose adjustments may not be...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug...

Effect of Hepatic Disease on Pharmacokinetics: Active Drug, Metabolite and Fraction of Metabolized Drug

In pharmacotherapy, monitoring drug concentrations is paramount, especially for drugs whose therapeutic effects hinge on both the active compound and its metabolite. Hepatic impairment profoundly influences drug potency by altering liver function. If the drug is more potent than its metabolite, impaired liver function amplifies drug activity due to elevated drug concentration levels. Conversely, if the metabolite holds greater potency, diminished liver function diminishes drug activity by...

Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
