Should I take Palbociclib/Pabociclib long-term?

Palbociclib has been approved since its approval for the treatment of women with advanced hormone receptor-positive breast cancer. Use in combination with an aromatase inhibitor or the anti-estrogen drug fulvestrant as part of anti-hormone therapy. For women whose cancer cells carry the HER2 (human epidermal growth factor receptor) receptor, palbociclib is not an option. Palbociclib can inhibit the cell division of cancer cells and slow down tumor growth. Depending on your doctor's instructions, patients may need to use palbociclib long-term during treatment.

Before starting palbociclib, your doctor will evaluate your condition and develop an individualized treatment plan. Depending on your specific situation, your doctor will determine whether long-term use of palbociclib is necessary. The length of treatment depends on several factors, including the stage of the disease, severity of the condition, and tolerance to palbociclib. During the treatment period, patients need to take medications according to the doctor's prescriptions and recommendations, and receive regular follow-up visits. Patients need to take it once a day for 3 weeks (21 days), then rest for 1 week (7 days), with a 4-week cycle. To ensure optimal absorption and effectiveness of the drug, patients are advised to take palbociclib at approximately the same time every day and strictly follow the doctor's instructions, neither taking more nor less.

While palbociclib offers hope to many patients, it can also cause side effects such as an increased risk of infection, decreased red blood cell count, fatigue, stomach upset, hair loss, diarrhea, and mouth sores. Therefore, patients should pay close attention to their body's reaction during taking it, communicate with their doctor in a timely manner, and follow the doctor's recommendations for medication and regular follow-up visits, which can improve the treatment effect and reduce the patient's risk of disease progression.
