Lung Cancer Treatment
Lung cancer is one of the most common and life-threatening cancers globally, causing a large number of cancer deaths. Medical science has made significant progress in offering different treatment options, such as chemotherapy, immunotherapy, targeted therapy, and surgery. The article offers a detailed overview of lung cancer treatment, its efficacy, risks, recovery, expense, and patient experience, highlighting options in India and China.
About the Disease
Lung cancer originates in the lungs, primarily due to uncontrolled cell growth in lung tissues. The two main types are:
- Non-Small Cell Lung Cancer (NSCLC) is the most common type, accounting for 80-85% of cases, and includes adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.
- Small Cell Lung Cancer (SCLC)—a more aggressive form (10–15% of cases) often linked to smoking.
Symptoms include persistent cough, chest pain, shortness of breath, and unexplained weight loss. Early detection improves treatment success rates.
Indications for Treatment
Treatment depends on cancer type, stage, and patient health. Common indications include:
- Early-stage (I-III) – Surgery, radiation, or chemotherapy.
- Advanced-stage (IV) – Targeted therapy, immunotherapy, or palliative care.
- Metastatic cases – Systemic treatments to control spread.
Procedure Details
Treatment procedures vary based on the approach:
- Surgery – Removal of tumors (lobectomy, pneumonectomy).
- Radiation Therapy – High-energy beams to kill cancer cells.
- Chemotherapy – Drugs to destroy rapidly dividing cells.
- Immunotherapy – Boosts the immune system to fight cancer (e.g., Keytruda, Opdivo).
- Targeted Therapy – Attacks specific genetic mutations (e.g., EGFR inhibitors).
Treatment Details: Chemotherapy, Immunotherapy, and Targeted Therapy
Chemotherapy
Uses drugs like cisplatin and carboplatin to kill cancer cells. Often combined with radiation (chemoradiation).
Immunotherapy
Checkpoint inhibitors (PD-1/PD-L1 inhibitors) help the immune system recognize and attack cancer cells. Common drugs:
- Pembrolizumab (Keytruda)
- Nivolumab (Opdivo)
Targeted Therapy
For cancers with specific genetic markers (EGFR, ALK, ROS1). Examples:
- Osimertinib (for EGFR mutations)
- Crizotinib (for ALK-positive tumors)
Effectiveness of Lung Cancer Treatments
- Early-stage NSCLC – Surgery + chemotherapy shows a 5-year survival rate of 60-80%.
- Advanced NSCLC – Immunotherapy improves survival by months to years.
- SCLC – Chemotherapy + radiation is standard, but recurrence rates are high.
Risks and Side Effects
- Chemotherapy – Nausea, hair loss, fatigue.
- Immunotherapy – Autoimmune reactions (colitis, pneumonitis).
- Targeted Therapy – Skin rashes, liver issues.
- Surgery – Infection, bleeding, reduced lung function.
Recovery and Aftercare
- Post-surgery: Pulmonary rehabilitation to improve lung capacity.
- Regular follow-ups for recurrence monitoring.
- Nutritional support and psychological counseling.
Cost and Availability
Costs vary by country and treatment type. India and China offer affordable options compared to the US.
