Lung cancer remains one of the most challenging and deadly cancers worldwide. In recent years, however, cutting-edge treatment options have dramatically improved outcomes for many patients—particularly in advanced stages. Among the most promising breakthroughs are Targeted Therapy and Immunotherapy, both offering new hope beyond traditional chemotherapy and radiation.
But the big question for patients and their families is: Which is better for advanced lung cancer—targeted therapy or immunotherapy? The answer is not straightforward, as it depends on several factors, including the type of lung cancer, specific genetic mutations, the patient's immune system, and overall health.
In this article, we’ll explore everything you need to know about these two advanced treatment options—how they work, who they’re for, their benefits, side effects, and how they compare. Action Cancer Hospital’s approach to lung cancer care will also be highlighted to give you insight into how a top-tier facility personalizes care.
Understanding Advanced Lung Cancer
Before diving into the therapies, it’s crucial to understand what advanced lung cancer means. Lung cancer is generally divided into two main types:
-
Non-Small Cell Lung Cancer (NSCLC) – About 85% of all lung cancer cases
-
Small Cell Lung Cancer (SCLC) – More aggressive and fast-growing
When cancer spreads beyond the lungs (Stage III or IV), it's considered advanced or metastatic. Traditional treatments like surgery or localized radiation are less effective at this stage, hence the need for systemic therapies like targeted drugs and immunotherapies.
What is Targeted Therapy?
Targeted Therapy is a cancer treatment that uses drugs or other substances to precisely identify and attack specific cancer cells without harming normal cells. It targets mutations or proteins that are responsible for cancer growth and survival.
In advanced NSCLC, targeted therapies often focus on:
-
EGFR mutations
-
ALK rearrangements
-
ROS1 mutations
-
BRAF, MET, RET, and NTRK gene alterations
How Targeted Therapy Works
These medications are usually taken orally or intravenously. They bind to the mutated protein or disrupt the signaling pathways that the cancer uses to grow. This makes the therapy highly specific and often more effective for certain patients.
What is Immunotherapy?
Immunotherapy helps your immune system recognize and attack cancer cells. Unlike targeted therapy, it doesn’t focus on mutations but rather on unleashing the immune system to do its job more effectively.
The most common form of immunotherapy used for lung cancer is immune checkpoint inhibitors, such as:
-
PD-1 inhibitors (e.g., Nivolumab, Pembrolizumab)
-
PD-L1 inhibitors (e.g., Atezolizumab, Durvalumab)
-
CTLA-4 inhibitors (e.g., Ipilimumab)
How Immunotherapy Works
Checkpoint inhibitors block proteins that stop the immune system from attacking cancer. This "releases the brakes" on immune cells, allowing them to recognize and destroy cancer more effectively.
Key Differences Between Targeted Therapy and Immunotherapy
| Feature | Targeted Therapy | Immunotherapy |
|---|---|---|
| Mechanism | Targets specific genetic mutations in cancer cells | Activates the immune system to fight cancer |
| Patient Eligibility | Requires the presence of specific mutations | Based on immune markers like PD-L1 expression |
| Response Time | Often produces quicker responses | May take longer to show effect |
| Side Effects | Usually milder, but can include skin rash, diarrhea | Can include immune-related issues (inflammation of organs) |
| Long-Term Effectiveness | Can become less effective as cancer mutates | Some patients show durable, long-term responses |
Who is a Candidate for Targeted Therapy?
Targeted therapy is only suitable for patients whose tumors have specific genetic mutations. To determine this, a comprehensive biomarker or molecular test is conducted on a tumor sample.
Common Mutations and Targeted Drugs
-
EGFR mutation – Erlotinib, Osimertinib
-
ALK rearrangement – Crizotinib, Alectinib
-
ROS1 fusion – Entrectinib
-
BRAF V600E mutation – Dabrafenib + Trametinib
At Action Cancer Hospital, next-generation sequencing (NGS) is routinely performed for all eligible lung cancer patients to ensure the most accurate treatment plan.
Who is a Candidate for Immunotherapy?
Immunotherapy is more versatile and may be used in:
-
Patients with high PD-L1 expression (>50%)
-
Those with no actionable mutations
-
Individuals who may not tolerate chemotherapy
-
Often combined with chemotherapy for broader effectiveness
Even patients with low or no PD-L1 expression may receive immunotherapy in combination with other treatments.
Combination Therapies: The Best of Both Worlds?
For some patients, combining therapies yields the best results. For instance:
-
Immunotherapy + Chemotherapy
-
Targeted Therapy + Angiogenesis inhibitors
-
Dual Immunotherapy (e.g., PD-1 and CTLA-4 inhibitors)
However, targeted therapy and immunotherapy are rarely used together due to increased toxicity. The treatment plan should always be personalized by a multidisciplinary team, like the one at Action Cancer Hospital.
Benefits of Targeted Therapy for Advanced Lung Cancer
-
Precision Treatment: Hits cancer where it hurts the most
-
Fewer Side Effects: Generally better tolerated than chemo
-
Rapid Results: Especially useful in symptomatic patients
-
Oral Administration: Easy to take at home
Benefits of Immunotherapy for Advanced Lung Cancer
-
Durable Responses: Some patients remain in remission for years
-
System-Wide Effect: Good for widespread or metastatic cancer
-
Better Quality of Life: No hair loss, nausea like chemo
-
Works When Other Treatments Fail: A valuable last line of defense
Side Effects to Watch Out For
Targeted Therapy Side Effects
-
Skin rash
-
Diarrhea
-
Liver function abnormalities
-
Nail or hair changes
Immunotherapy Side Effects
-
Fatigue
-
Joint pain
-
Pneumonitis (lung inflammation)
-
Colitis (bowel inflammation)
-
Endocrine issues (thyroid problems)
While side effects are usually manageable, early detection and intervention are key.

With state-of-the-art diagnostics and a team of oncologists, pulmonologists, and radiologists, Action Cancer Hospital ensures every patient receives a tailored treatment plan that maximizes effectiveness and minimizes side effects.
FAQs: Targeted Therapy vs Immunotherapy in Lung Cancer
Q: Can I receive both therapies at the same time?
A: Usually not, due to higher risk of severe side effects. However, sequential use is possible in some cases.
Q: Is chemotherapy still used?
A: Yes, especially in combination with immunotherapy or when no mutations are found.
Q: How long do these treatments last?
A: Targeted therapy is continued as long as it works. Immunotherapy may last up to 2 years or more, depending on response.
Conclusion: Which is Better—Targeted Therapy or Immunotherapy?
There’s no universal answer to which therapy is best for advanced lung cancer. The choice depends on individual patient factors like tumor genetics, immune markers, and overall health. Targeted therapy is ideal for patients with actionable mutations, while immunotherapy works well in those with high PD-L1 expression or no mutations.
At Action Cancer Hospital, every patient undergoes comprehensive evaluation to determine the most effective, personalized treatment plan.
