Targeted Therapy: What It Is, Process & Side Effects

In recent years, the field of oncology has witnessed significant advancements, and one of the most promising developments is targeted therapy. Unlike traditional cancer treatments such as chemotherapy and radiation, targeted therapy aims to specifically target the cancer cells while minimizing damage to normal cells. This precision medicine approach offers new hope for patients battling cancer, enhancing treatment efficacy and reducing side effects.

What is Targeted Therapy?

Targeted therapy is a form of cancer treatment designed to specifically target and disrupt the molecular pathways that are essential for cancer cell growth and survival. Unlike conventional therapies that attack all rapidly dividing cells, targeted therapy focuses on specific molecules involved in the cancer process. These molecules are often proteins or genes that play a critical role in the cancer’s development and progression.

The primary goal of targeted therapy is to interfere with the cancer cell’s ability to grow and spread. By binding to specific proteins or genes in the cancer cells, targeted drugs can inhibit their function or signal the immune system to destroy them. This precision approach helps in minimizing the damage to healthy cells and reduces the overall side effects compared to traditional treatments.

The Process of Targeted Therapy

The process of targeted therapy typically begins with a thorough diagnostic evaluation. This includes identifying the specific genetic mutations or molecular targets present in the cancer cells. Once the targets are identified, a tailored treatment plan is developed.

1. Diagnosis and Testing: The first step involves various tests, such as blood tests, biopsies, and genetic testing, to identify specific biomarkers associated with the cancer. This information is crucial for determining the most effective targeted therapy for the patient.
2. Treatment Plan: Based on the test results, a personalized treatment plan is formulated. This plan may include targeted drugs, which can be oral medications or intravenous infusions. The treatment may be used alone or in combination with other therapies.
3. Administration: Targeted therapy is administered according to the plan. Regular follow-ups and monitoring are essential to evaluate the effectiveness of the treatment and to make necessary adjustments.
4. Ongoing Monitoring: Throughout the treatment, patients undergo periodic evaluations to monitor the response to therapy and to manage any side effects. Adjustments to the treatment plan may be made based on the patient’s progress.

Side Effects of Targeted Therapy

While targeted therapy offers several advantages, it is not without side effects. The side effects vary depending on the type of targeted therapy and the individual patient’s response. Common side effects include:

1. Skin Reactions: Rashes, dryness, or itching are common with some targeted therapies.
2. Gastrointestinal Issues: Nausea, diarrhoea, and changes in appetite can occur.
3. Fatigue: Patients may experience tiredness or weakness.
4. Blood Issues: Some targeted therapies can affect blood cell counts, leading to anaemia or increased risk of infection.
5. Liver Problems: Abnormal liver function tests may be observed, requiring close monitoring.

It is essential for patients to discuss potential side effects with their healthcare provider and to report any symptoms promptly. The management of side effects is a crucial part of the treatment process, and adjustments can often be made to alleviate these issues.
