Treating advanced liver cancer is challenging, and few treatment options are available. Regarding liver cancer treatments, these two drugs are widely used and extensively studied. This article focuses on looking at how these two drugs differ, their Mode of Action, and how clinical trials have informed their application in liver cancer treatment.

1. Mechanism of Action

Understanding the functioning of these medications is essential for understanding their effectiveness and the potential side effects they may cause. Lenvatinib is a type of TKI—a cancer-fighting agent that targets multiple RTKs. It includes targets such as VEGFR1-3, FGFR1-4, PDGFRα, and c-Met receptors.

By simultaneously targeting multiple RTKs, it is more effective in preventing tumor growth and spread. Sorafenib is also a TKI, but it primarily targets VEGFR2 and c-Met. These drugs have prolonged survival and prevent the progression of cancer in patients with liver cancer.

2. Clinical Trials and Efficacy

The research studies for lenvatinib and sorafenib have provided valuable insights into their effectiveness in treatment for hepatocellular carcinoma. There was this big test called REFLECT where they compared lenvatinib with sorafenib in people with liver cancer that had untreated.

The results showed that lenvatinib significantly improved OS compared to sorafenib, with a average overall survival of 13. 6 months versus 12. 7 months, respectively. The third phase Sorafenib Hepatocellular Carcinoma Assessment trial (SHARP) trial, which compared sorafenib to sugar pill, demonstrated a average overall survival of 10. 7 months for sorafenib versus 7. 9 months for sugar pill.

3. Side Effects and Management

Both drugs can cause numerous side effects like palmar-plantar erythrodysesthesia, loose stools, hypertension, and feeling tired. It’s really important to deal with these side effects to make sure people can maintain a good quality of life and sticking with their treatment. To deal with the side effects, we might modify the dosage, provide some assistance, or use drugs like antiloose stoolsls and blood pressure medications.

4. Cost and Accessibility

The price of these drugs can be really high and a issue, especially in places where high cost of healthcare. How easy it is to get these drugs also influenced by insurance and health policies. To make these treatments more accessible, we’re looking at things like assistance programs, generic drugs, and international teamwork to decrease expenses.

5. Future Directions

Continual research is being conducted to see if combining lenvatinib and sorafenib with additional treatments such as immunotherapy can enhance effectiveness in treating liver cancer. There’s also a effort to discover biomarkers which inform us patients who may positively respond to treatment and aid in personalizing treatments more effectively.
