Why can targeted lung cancer drugs be "drug-resistant"? 🤔

🫁 Part 1 Targeted lung cancer drug

Why is it "resistant"?

Many lung cancer patients after diagnosis are often relieved to know that they can use "Targeted Therapy," because compared to chemotherapy or radiotherapy, this group often has fewer side effects, is convenient to eat, and effectively controls the disease in patients with gene mutations that match the drug.

But on the other hand, a small number of patients always have the question that comes to mind:

💭 "When will the drug be stubborn?"

💭 "Will there be a day when the drug stops working?"

📌 Clinically, the problem of "drug resistance" is a real one, and almost no one can avoid it all because cancer cells are constantly capable of adapting and mutating.

However, it is important to know that the duration of drug resistance does not depend on luck alone, but some lifestyle and self-care behaviors can directly affect the speed of resistance.

🧬 Why do drugs target drug resistance?

In the simplest way, cancer cells are like "a group of learned and evolutionary villains."

💊 In the early stages of treatment, the drug aims to attack cancer cells with specific mutations, reduce cancer nodules, improve symptoms, and disease is controlled quickly.

⚠️ But in general, there are still some cancer cells left, and under drug pressure for a long time, these cells may gradually adapt, develop further mutations, and ultimately develop into drug resistance, so that once-effective drugs do not control the disease.

📖 drug resistance is divided into two main characteristics:

1️⃣ Natural drug resistance.

It is a long-term process of spontaneous cancer cell evolution. Most patients have the opportunity to encounter it, but the duration is different.

2️⃣ Accelerated drug resistance from external factors.

It is caused by inappropriate behavior, such as taking uneven drugs, taking inappropriate care of the body, or using drugs and products without consulting a doctor, which is a preventable part.

📊 Clinical data showed that patients who took proper care of themselves and strictly followed medical advice often had longer periods of pre-resistance than those who took uneven doses.

So to maintain the effectiveness of the drug for as long as possible, it is important not just to take the drug, but to take care of yourself properly in daily life. 💙

⚠️ Important matter 1:

Do not stop medication, adjust medication, or take medication unevenly by yourself.

This is one of the most common drug resistance causes in lung cancer patients taking targeted drugs.

💬 Many patients, as symptoms improve, often begin to reduce their dose, some stop because they think the disease has improved, or sometimes forget to take medication and do not pay much attention, but these behaviors may allow surviving cancer cells to recover and adapt to drug resistance faster.

💡 The main reason is that targeted drugs need to stabilize blood levels to continuously suppress cancer cell growth. If drug levels swing too much, disease control effectiveness may be reduced.

✅ Correct drug guidelines

• ⏰ should take the same time every day and try to keep the same time as possible.

• 💊 If you forget to take your medicine and are far from the next meal, take it as soon as you can.

• 🚫 If the next meal is near, skip it and do not double the dose.

• 🙅‍♂️ Even if the condition improves, the drug should not be stopped.

• 👨‍⚕️ Drug replacement, dose reduction, or drug increase should be supervised only by a doctor.

⚠️ Important matter 2:

Be careful of supplements, herbs, or medications that may hit the drug.

💊 Many patients often need to nourish the body further during treatment, so they buy supplements, herbs, Chinese medicines, or folk recipes to eat for themselves, thinking that they will improve the body.

⚠️ But in reality, some products can interfere with the function of the liver and drug metabolism, causing blood-targeting drug levels to change, resulting in reduced drug effectiveness and potentially speeding up drug resistance.

🚨 Something to be extra careful about.

• 🌿 Herbs or folk medicines whose components are unknown clearly

• 💰 large quantities of supplements such as ginseng, soft antlers or Linzhi mushroom spores

• 💊 Some antacids, such as Omeprazole, which may reduce the absorption of some targeted drugs.

• ☯️ strong Chinese herbs or may contain heavy metals.

📌 key to remember

If you want to use any additional drugs, supplements, or health products during the treatment period, your doctor should be consulted first every time and should not be used by yourself according to general instructions from the Internet or those around you.

💭, because what sometimes seems to "nourish the body" can unconsciously reduce the effectiveness of treatment.
