Can eflornithine tablets cure the disease?

Eflornithine tablets (eflornithine) is an ornithine decarboxylase (ODC) inhibitor, which mainly inhibits cell proliferation and has anti-tumor effects by blocking the polyamine synthesis signaling pathway required for the growth of cancer cells. In recent years, the drug has been used to treat certain patients with neuroblastoma who are sensitive or partially responsive to other treatments, especially children and adults who are on maintenance treatment or in remission.

In this context, the role of eflornithine is not to directly "kill" cancer cells, but to slow down the proliferation of cancer cells and help prolong progression-free survival and overall efficacy. Therefore, if "cure" is understood as the complete elimination of cancer without the need for subsequent treatment, then eflornithine does not have the ability to cure cancer as a single drug in most cases. However, if it is regarded as a maintenance treatment drug to control the disease, prolong survival, and reduce recurrence, its clinical significance is very important.

Especially for patients who have received multiple treatment options but still have residual lesions, long-term oral administration of eflornithine can effectively control the tiny residual tumors and inhibit the tendency of re-growth. In some studies, the drug has been used in the maintenance phase after combined chemotherapy or immunotherapy, showing the potential to delay recurrence, especially for tumor types that are highly dependent on the ODC pathway.

It is worth noting that the therapeutic effect is closely related to the duration of medication, the patient’s genetic characteristics and the overall treatment strategy. Although eflornithine has the advantage of "chronic control" treatment in certain diseases, it still needs to be used in conjunction with the concept of precision medicine to improve its overall therapeutic effect. In short, eflornithine is one of the important drugs in the current treatment of cancers such as neuroblastoma. Although it cannot be used as a complete cure, it plays a positive role in delaying disease progression and consolidating treatment results.
