Non-Small Cell Lung Cancer (NSCLC) Treatment
Non-small cell lung cancer (NSCLC) is the most prevalent type of lung cancer, representing approximately 85% of all lung cancers. Similar to small cell lung cancer (SCLC), NSCLC develops slowly but may progress rapidly if left untreated. Improved treatment of NSCLC using chemotherapy, immunotherapy, targeted therapy, and surgery has greatly enhanced survival rates. This article discusses NSCLC treatment options, efficacy, side effects, costs, and patient experience, with emphasis on India and China.
About the Disease
NSCLC originates in the epithelial cells of the lungs and is categorized into three main subtypes:
- Adenocarcinoma (most common, often in non-smokers)
- Squamous cell carcinoma (linked to smoking)
- Large cell carcinoma (less common, aggressive)
Symptoms include persistent cough, chest pain, shortness of breath, and unexplained weight loss. Diagnosis involves imaging (CT/PET scans), biopsies, and molecular testing to identify genetic mutations (EGFR, ALK, ROS1).
Indications for Treatment
Treatment depends on the cancer stage:
- Stage I-II: Surgery (lobectomy, pneumonectomy) or radiation.
- Stage III: Chemoradiation followed by immunotherapy.
- Stage IV (metastatic): Systemic therapies (targeted therapy, immunotherapy, chemotherapy).
Procedure Details
- Surgery: Removal of tumors (wedge resection, segmentectomy).
- Radiation Therapy: High-energy beams to kill cancer cells (SBRT for early-stage).
- Chemotherapy: Drugs like cisplatin, carboplatin, and pemetrexed.
- Immunotherapy: Checkpoint inhibitors (pembrolizumab, nivolumab).
- Targeted Therapy: Drugs like osimertinib (for EGFR mutations), crizotinib (for ALK/ROS1).
Treatment Details
Chemotherapy
Used for advanced NSCLC, often combined with immunotherapy. Common drugs:
- Platinum-based (cisplatin, carboplatin)
- Pemetrexed (for non-squamous NSCLC)
Immunotherapy
Boosts the immune system to attack cancer cells:
- PD-1/PD-L1 inhibitors (pembrolizumab, nivolumab, atezolizumab)
- CTLA-4 inhibitors (ipilimumab – less common)
Targeted Therapy
For cancers with specific genetic mutations:
- EGFR inhibitors (osimertinib, gefitinib)
- ALK inhibitors (alectinib, lorlatinib)
- ROS1 inhibitors (crizotinib, entrectinib)
Effectiveness
- Early-stage (I-II): 5-year survival ~60-80% with surgery.
- Stage III: 15-30% 5-year survival with chemoradiation + immunotherapy.
- Stage IV: Median survival ~12-18 months, but newer therapies extend life.
Risks and Side Effects
- Chemotherapy: Nausea, fatigue, hair loss, low blood counts.
- Immunotherapy: Autoimmune reactions (rash, colitis, pneumonitis).
- Targeted Therapy: Skin rash, diarrhea, liver issues.
Recovery and Aftercare
- Post-surgery: Pulmonary rehabilitation, pain management.
- During therapy: Regular scans, managing side effects.
- Long-term: Lifestyle changes (quit smoking, healthy diet).
Cost and Availability
Treatment costs vary by country and therapy type.

Treatment in India and China
- India: Affordable care with leading hospitals (Tata Memorial, Apollo).
- China: Advanced therapies (CAR-T trials, proton therapy).
Patient Experiences
Many patients report improved quality of life with immunotherapy, while targeted therapy offers hope for mutation-positive cases. Side effects vary, requiring personalized care.
Ongoing Clinical Trials in China

- NCT04248829: PD-1 inhibitor + anti-angiogenesis therapy.
- NCT04379635: Novel ALK inhibitor (ensartinib) trials.
FAQ
Q: What is the best treatment for NSCLC?
A: Depends on stage and mutations—surgery (early), immunotherapy/targeted therapy (advanced).
Q: Is NSCLC curable?
A: Early-stage can be cured; advanced is managed as a chronic condition.
Q: How much does NSCLC treatment cost in India?
A: 5,000−20,000 for full treatment, much cheaper than the West.
Q: What are the newest treatments?
A: Bispecific antibodies, KRAS inhibitors (sotorasib), and personalized vaccines.
