How to deal with common side effects during Bortezomib treatment

Bortezomib is a proteasome inhibitor widely used in the treatment of multiple myeloma and certain lymphomas. Although its efficacy is significant, there are many common side effects during treatment. Patients need to actively identify and deal with it appropriately when receiving bortezomib treatment to ensure that the efficacy is maximized and the quality of life is not greatly affected. This article will introduce in detail the common side effects and effective countermeasures during bortezomib treatment.

1. Peripheral neuropathy (PN)

Peripheral neuropathy is the most common and bothersome side effect of bortezomib, manifesting as numbness, tingling, burning or even pain in the hands and feet. In severe cases, it may affect daily life. Response methods include:

Prevention is the priority, and neurological assessments should be carried out regularly before and during treatment to detect early symptoms in a timely manner.

Medication adjustment: if the symptoms are mild, the dosage can be appropriately reduced or the dosing interval extended; if the symptoms worsen, the medication needs to be suspended.

Symptomatic treatment involves applying vitaminsB family, neurotrophic drugs and analgesics to relieve symptoms; some patients can use antidepressants or anti-epileptic drugs to relieve neuralgia.

Adjust your lifestyle to avoid cold stimulation and mechanical compression, keep your hands and feet warm, and reduce nerve stimulation.

2. Digestive system reaction

Bortezomib often causes gastrointestinal discomfort such as nausea, vomiting, diarrhea, and constipation. Response measures include:

Anti-nausea medications, such as 5-HT3 receptor antagonists, are given prophylactically, especially early in treatment.

Adjust your diet, adopt a light, easy-to-digest, less greasy diet, and avoid irritating foods.

Stay hydrated to prevent dehydration, especially if diarrhea is severe.

Use antidiarrheal medications or laxatives based on specific symptoms to keep bowel function in balance.

3. Hematological toxicity

Bortezomib can cause bone marrow suppression, manifested by leukopenia, thrombocytopenia, and anemia, and increase the risk of infection and bleeding. Coping strategies include:

Monitor blood routine regularly to detect blood cell decline early.

Pause or adjust the dose if necessary to avoid excessive suppression of bone marrow function.

To prevent infection, pay attention to personal hygiene and avoid contact with sources of infection.

Supplementary hematopoietic support therapy, such as erythropoietin or granulocyte colony-stimulating factor (G-CSF), may be considered in severe cases. Blood transfusion support may be considered.

4. Cardiotoxicity and others

Bortezomib occasionally causes cardiotoxicity such as arrhythmia and cardiac dysfunction. Pay attention to cardiac symptoms during treatment. It is recommended to evaluate cardiac function before treatment, monitor heart rate and electrocardiogram during treatment, and deal with any abnormalities in a timely manner. Other rare side effects such as rash, fever, fatigue, etc. also need to be paid attention to and reported to the doctor in time.

5. Psychological and quality of life support

Long-term treatment may cause psychological stress and reduced quality of life. It is recommended that patients maintain a positive attitude, participate in psychological consultation or support groups, reasonably arrange work and rest, exercise appropriately, and improve tolerance.

In summary, although bortezomib treatment is associated with a variety of side effects, most side effects can be effectively controlled through early identification, individualized adjustment of treatment plans and comprehensive symptomatic support. Patients should cooperate closely with medical staff, conduct regular reviews, and provide timely feedback on symptoms to jointly achieve the dual goals of disease control and quality of life.
