What are the possible side effects of stopping selinesol suddenly?

Selinexor As a selective nuclear export inhibitor (SINE drug), it blocks the abnormal export of multiple tumor-related proteins by inhibiting the function of XPO1 protein, thereby inducing cancer cell apoptosis. It has shown good efficacy in the treatment of multiple myeloma and certain lymphomas. However, because its mechanism of action directly affects the transport and homeostasis of proteins in the nucleus, if the patient suddenly stops taking the drug without the guidance of a doctor, it may cause a variety of potential adverse reactions and clinical problems.

One of the most common problems is rebound progression of the underlying disease. After many patients use selinesol to control their disease, tumor activity is temporarily suppressed. Once the drug is stopped suddenly, tumor cells may quickly resume proliferation, leading to recurrence of symptoms and even accelerated disease progression. In addition, some patients may experience systemic inflammatory reactions after drug withdrawal. This is due to the reduction in tumor cell death and the increase in the release of inflammatory cytokines in the body again. Clinical manifestations include fatigue, fever, pain, etc.

In addition, selinesol affects multiple physiological systems in the body, and may also interfere with the patient's immune regulatory function after discontinuation of the drug. Especially when combined with hormonal drugs or other immunosuppressants, sudden discontinuation of the drug may cause abnormal immune system responses and induce infection, gastrointestinal discomfort, or neurological symptoms.

At the psychological level, some patients gradually adapt to the side effects of the drug (such as loss of appetite, fatigue, etc.) during use. If treatment is suddenly interrupted, mood swings or increased anxiety will occur, affecting the quality of daily life. In order to reduce these potential risks, patients should strictly follow the doctor's assessment and recommendations when planning to discontinue medication or adjust dosage, and adopt a gradual reduction method instead of abrupt discontinuation of medication, especially in multi-line treatment or combination therapy.
