Introduction

Cancer treatment has entered a new era where the body's own immune system can be harnessed to recognise and destroy malignant cells. Immunotherapy for cancer represents a suite of biological treatments that enhance or modify immune function to fight cancer. In Amritsar and across Punjab, advances in immune-based therapies — from checkpoint inhibitors to cellular therapies like CAR-T — are changing outcomes for many patients.

Globally, cancer remains a major public health challenge. According to GLOBOCAN data, there were an estimated about 19.3 million new cancer cases worldwide in 2020 and roughly 10 million deaths. In India, recent national estimates indicate over 1.3 million new cancer diagnoses annually, with numbers rising as screening, detection and life expectancy improve. In Punjab, including Amritsar and nearby districts, increased awareness and regional cancer registries highlight a steady rise in cancers where immunotherapy plays an important role — for example, lung cancer, head and neck cancers, bladder cancer and melanoma.

This article explains what immunotherapy is, how checkpoint inhibitors such as PD-1 and PD-L1 blockers work, the role of CAR-T and cancer vaccines, who may benefit, the side effects and monitoring required, cost considerations in Amritsar and Punjab, and how Livasa Amritsar supports patients seeking advanced immune-based cancer care.

What is immunotherapy and how does it work?

Immunotherapy is a class of cancer treatments that stimulate, enhance or restore the immune system's natural ability to fight cancer. Unlike chemotherapy, which directly kills fast-dividing cells, or targeted therapy, which blocks specific molecular pathways inside cancer cells, immunotherapy works by changing how the immune system recognises and responds to tumour cells.

The immune system uses specialised cells such as T lymphocytes (T cells), natural killer cells and antigen-presenting cells to find and eliminate threats. Tumours develop strategies to evade immune detection — for example, by exploiting immune checkpoints (molecular brakes) that normally prevent excessive immune activation. Immunotherapy can:

• Release immune brakes so T cells attack cancer (checkpoint inhibitors).
• Introduce modified immune cells that recognise cancer (CAR-T therapy).
• Provide immune-stimulating proteins such as cytokines or monoclonal antibodies.
• Teach the immune system to recognise tumour-specific antigens via vaccines.

At the cellular level, drugs that block PD-1, PD-L1 or CTLA-4 checkpoints stop tumour cells from telling T cells to stand down. This reinvigorates an anti-tumour attack, which can lead to durable responses in a subset of patients. The exact mechanisms vary by therapy, and patient selection often uses biomarkers such as PD-L1 expression, tumour mutational burden or microsatellite instability status to predict benefit.

In practical terms, immunotherapy administration and monitoring differ from conventional treatments. Response patterns can be slower or atypical, and rare but serious immune-related side effects can affect any organ system. Consequently, centres that offer immunotherapy, including Livasa Amritsar, emphasise multidisciplinary care, close monitoring and rapid adverse event management to maximise safety and outcomes.

Types of immunotherapy available in Amritsar and Punjab

Immunotherapy is not a single treatment but a family of approaches. Many of these are available in major Indian cities and increasingly in regional centres such as Amritsar. Below are the principal types, with short descriptions and how they are used locally:

• Checkpoint inhibitors (PD-1, PD-L1, CTLA-4): Monoclonal antibodies that block immune checkpoints and reactivate T cells. Examples include pembrolizumab and nivolumab (PD-1 inhibitors), atezolizumab (PD-L1 inhibitor) and ipilimumab (CTLA-4 inhibitor). These are used for lung, melanoma, head and neck, bladder, renal and several other cancers and are increasingly prescribed at Livasa Amritsar and other centres in Punjab.
• CAR-T cell therapy: Chimeric antigen receptor T-cell therapy involves collecting a patient’s T cells, genetically modifying them to target a tumour antigen, expanding them and infusing them back. CAR-T has transformed outcomes for certain blood cancers. Availability in Punjab is growing through referral pathways; local centres coordinate with national CAR-T providers and clinical trial programmes.
• Cancer vaccines: Therapeutic vaccines aim to prime or boost an immune response against tumour antigens. Some vaccines are tumour-type specific and others are experimental in clinical trials. Cancer vaccine clinical trials are active in India, and patients in Amritsar can be assessed for eligibility.
• Monoclonal antibodies and antibody-drug conjugates: These are targeted biologics that may directly attack tumour cells or deliver toxins. Many are combined with immunotherapy or used sequentially.
• Cytokine therapy and adoptive cell transfer: Interleukins or interferons can stimulate immune activity but may have systemic effects; adoptive transfer includes TIL (tumour-infiltrating lymphocyte) therapies being explored in specialised centres.
• Oncolytic virus therapy: Viruses that selectively infect and kill cancer cells and stimulate immunity; these are currently more experimental and available through trials or specialised centres.

In Amritsar, Livasa Amritsar provides access to many checkpoint inhibitors, coordinates referrals for CAR-T therapy and supports patients wishing to join cancer vaccine or immunotherapy clinical trials in Punjab and India. Treatment choice is personalised based on cancer type, stage, biomarkers, prior therapies and patient goals.

Checkpoint inhibitors: PD-1, PD-L1 and CTLA-4 explained

Checkpoint inhibitors are the most widely used form of immunotherapy in solid tumours. They interrupt the molecular signals tumours use to deactivate immune cells. The three main targets are PD-1 (programmed cell death protein 1), PD-L1 (its ligand) and CTLA-4 (cytotoxic T-lymphocyte associated protein 4).

PD-1 and PD-L1 inhibitors: PD-1 is expressed on T cells; when it binds PD-L1 on tumour or immune cells, T cell activity is suppressed. Drugs that block PD-1 (e.g., nivolumab, pembrolizumab) or PD-L1 (e.g., atezolizumab, durvalumab) prevent this interaction and restore T cell function. Indications include:

• Lung cancer (non-small cell lung cancer) — both first-line and later-line settings depending on PD-L1 status.
• Melanoma — when used alone or in combination with CTLA-4 inhibitors.
• Bladder and urothelial cancers — where PD-L1 expression may guide use.
• Head and neck cancers — where PD-1 inhibitors can improve survival in some patients.
• Hodgkin lymphoma — characterized by high sensitivity to PD-1 inhibitors.

CTLA-4 inhibitors: CTLA-4 acts earlier in immune activation pathways and blocking it (e.g., ipilimumab) can amplify immune responses. Often CTLA-4 inhibitors are used in combination with PD-1 inhibitors for certain cancers (for instance, advanced melanoma) to increase response rates, albeit with higher rates of immune-related toxicity.

Biomarkers: PD-L1 testing on tumour tissue helps predict likelihood of response to PD-1/PD-L1 therapy. However, responses can occur even with low PD-L1 expression. Other predictive measures such as tumour mutational burden (TMB) and microsatellite instability (MSI) status are increasingly used to guide therapy.

At Livasa Amritsar, oncologists offer comprehensive biomarker testing, counselling on likely benefits and risks, and a tailored plan for checkpoint inhibitor therapy. For patients in Amritsar and across Punjab, checkpoint inhibitor therapy offers a less toxic alternative to traditional chemotherapy in many settings and can produce long-lasting remissions in responsive patients.

Who is eligible for immunotherapy and which cancers benefit most?

Eligibility for immunotherapy depends on several factors: the type and stage of cancer, biomarker results, prior treatments, performance status (overall health), and patient preferences. Oncologists in Amritsar and throughout Punjab assess each case individually to determine the best approach.

Cancers with strong evidence of benefit from immunotherapy include:

• Non-small cell lung cancer (NSCLC) — PD-1/PD-L1 inhibitors are established in first-line and subsequent lines, often guided by PD-L1 expression.
• Melanoma — checkpoint inhibitor combinations (PD-1 + CTLA-4) improve survival in many advanced cases.
• Bladder (urothelial) cancer — PD-1/PD-L1 inhibitors are approved for advanced disease.
• Renal cell carcinoma — combinations of PD-1 inhibitors with targeted agents or CTLA-4 have shown benefit.
• Head and neck squamous cell carcinoma — PD-1 inhibitors improve outcomes in recurrent/metastatic disease.
• Hematological malignancies such as Hodgkin lymphoma and select lymphomas respond well to PD-1 blockade; CAR-T has shown transformative outcomes in certain leukemias and lymphomas.

Some general rules that influence eligibility:

• Biomarker positivity (e.g., PD-L1 expression or MSI-high) may prioritise immunotherapy for some cancers.
• Patients with autoimmune disease or prior organ transplants require careful evaluation because immunotherapy can worsen immune-mediated conditions.
• Pediatric immunotherapy is an evolving field — certain CAR-T and vaccine approaches are available for children with specific blood cancers under specialist care.

Practical pathway in Amritsar: At Livasa Amritsar, patients undergo multidisciplinary review including medical oncology, pathology for biomarker testing, radiology and supportive care teams. This ensures that immunotherapy eligibility decisions are evidence-based, personalised and aligned with the patient's medical condition and goals.

Benefits, limitations and how immunotherapy compares to other treatments

Immunotherapy offers several unique benefits but also important limitations. Understanding these helps patients and families make informed decisions:

• Potential for durable responses: For some cancers, a fraction of patients achieve long-term remission after immunotherapy, something rarely seen with chemotherapy alone.
• Different side-effect profile: Instead of the classic nausea, hair loss or bone marrow suppression from chemotherapy, immunotherapy can cause immune-related inflammation of organs such as lungs (pneumonitis), liver (hepatitis), colon (colitis), skin and endocrine glands.
• Biomarker-driven selection: Tests such as PD-L1, MSI and TMB can guide treatment choices.
• High cost and access challenges: Some immunotherapies, particularly CAR-T, are expensive and require specialised infrastructure.

For clarity, the table below summarises differences between common treatment categories and their typical advantages and recovery considerations:

In many cancers, combinations — such as immunotherapy plus targeted therapy or chemotherapy — can improve response rates. However, combination approaches typically increase the risk of side effects and cost, requiring experienced teams to manage therapy safely. Livasa Amritsar offers multidisciplinary evaluation to determine whether single-agent or combination approaches are the best option for each patient in Amritsar and neighboring regions of Punjab.

Side effects, monitoring and management of immune-related toxicities

Immune-related adverse events (irAEs) occur because immunotherapy can cause inflammatory reactions in normal tissues. These events can be mild or severe, and early recognition and management are crucial to prevent complications. Commonly affected organs include the skin, colon, lungs, liver, endocrine glands (thyroid, pituitary) and less commonly heart, kidneys and nervous system.

Typical irAEs and symptoms:

• Skin: Rash, itching.
• Gastrointestinal: Diarrhoea, abdominal pain, colitis.
• Lungs: Cough, breathlessness — pneumonitis can be severe.
• Liver: Elevated liver enzymes or hepatitis.
• Endocrine: Fatigue, weight changes, dizziness from thyroiditis or adrenal insufficiency.
• Neurological or cardiac: Rare but serious events that require immediate attention.

Management principles:

• Early recognition through education and scheduled monitoring (blood tests, symptom checks).
• Temporary or permanent treatment interruption depending on toxicity severity.
• Use of immunosuppressive therapy — typically corticosteroids — for moderate to severe irAEs. Other immunomodulators (e.g., infliximab) may be required in steroid-refractory cases.
• Close coordination with organ-specific specialists (e.g., pulmonologists, endocrinologists, gastroenterologists).

At Livasa Amritsar we emphasise patient education before starting therapy: patients and families receive clear guidance on symptoms that should prompt immediate contact, 24/7 helpline instructions, and a structured follow-up schedule. This rapid-response approach helps reduce complications and supports safer use of therapies such as PD-1 inhibitors, PD-L1 inhibitors and combination regimens in Amritsar and the wider Punjab region.

Costs, insurance and financial considerations in Amritsar and Punjab

Cost is a significant consideration for many patients exploring immunotherapy in Amritsar and across Punjab. Prices vary by drug, dosing schedule, combination regimens, inpatient monitoring needs and whether cellular therapies or clinical trials are involved. Below is an indicative cost comparison to provide a realistic framework; actual costs will be tailored during consultation and depend on procurement and patient-specific factors.

These ranges are indicative. Insurance coverage in India varies; some public and private insurers now cover certain immunotherapies, while others require pre-authorisation. Livasa Amritsar provides financial counselling to explore insurance claims, government schemes, patient assistance programmes from pharmaceutical companies, and options to participate in clinical trials which may reduce out-of-pocket costs.

If cost is a concern, discuss alternatives during your oncology consultation — in some cases, sequencing treatments or enrolling in a clinical trial can be practical pathways to access advanced therapies.

How to prepare, what to expect during treatment and long-term follow-up

Preparation for immunotherapy typically involves a baseline assessment and tests to ensure safety and suitability. Steps include:

• Comprehensive clinical evaluation and medical history.
• Baseline blood tests (CBC, liver and renal function), endocrine tests (thyroid), and imaging to document disease extent.
• Biomarker testing (PD-L1, MSI, TMB) on tumour tissue where indicated.
• Vaccination review and infection screening (e.g., latent tuberculosis) in select cases.
• Patient education on potential side effects and emergency contact pathways.

During treatment:

• Checkpoint inhibitors are usually given as intravenous infusions every 2–6 weeks depending on the drug and dose — outpatient infusion clinics such as Livasa Amritsar manage these visits.
• Regular follow-up includes symptom review and periodic blood tests and imaging to assess response.
• Response to immunotherapy can be atypical: some patients have initial tumour enlargement (pseudoprogression) due to immune infiltration before improvement. Oncologists interpret scans in the clinical context.

Long-term follow-up:

• Even after treatment stops, patients require monitoring for late immune-related side effects and for disease recurrence.
• Survivorship care plans include endocrine assessment, management of chronic irAEs and rehabilitation services.

For patients traveling from surrounding areas of Punjab to Livasa Amritsar, the team provides a clear roadmap for appointments, local accommodation assistance if needed, and telemedicine follow-up where appropriate to minimise travel burden while ensuring safety.
