TIL Therapy: Harnessing Your Body’s
Natural Defenses Against Cancer
Tumor-Infiltrating Lymphocyte (TIL) therapy is a groundbreaking, FDA-approved cellular treatment. It takes the immune cells that have already recognized your tumor, multiplies them in a specialized lab, and returns them to fight the cancer with renewed strength. We provide clear, unbiased information to help you understand if this path is right for you.
The 5-Step TIL Therapy Journey
Unlike CAR-T which engineers cells, TIL therapy uses your body's own tumor-reactive immune cells — already selected by nature to recognize your specific cancer.
Tumor Resection
A small piece of tumor tissue is surgically removed, often from an accessible site like a skin metastasis or lymph node.
TIL Isolation
In a specialized GMP laboratory, tumor-infiltrating lymphocytes are carefully extracted from the tumor fragments.
Expansion (22-33 days)
TILs are cultured with interleukin-2 (IL-2), multiplying from thousands to 50-100+ billion cells — a targeted army.
Lymphodepletion
You receive a short course of chemotherapy to eliminate competing immune cells and create "space" for the new TILs.
TIL Infusion + IL-2
Expanded TILs are infused intravenously over ~30 minutes, followed by IL-2 support to sustain their activity.

Is TIL Therapy Right for You?
A thorough, expert review of your specific case ensures this intensive therapy is a viable option, helping you avoid unnecessary stress and expenses.
Typically a Good Candidate If
- Diagnosed with unresectable or metastatic melanoma.
- Disease progressed after PD-1 inhibitor therapy.
- ECOG performance status 0-1 (fully or mostly active).
- Adequate heart, lung, liver, and kidney function.
- At least one resectable tumor site is available for TIL harvest.
May Not Be Suitable If
- No resectable tumor site is available (TILs must come from your tumor).
- ECOG performance status 3-4 (bedridden >50% of waking hours).
- Severe cardiac or pulmonary disease.
- Active uncontrolled infection or severe autoimmune disease.
Requires Expert Review If
- Non-melanoma solid tumors (currently available via clinical trials).
- Age >70 years (evaluated on a case-by-case physiologic basis).
- History of severe immune-related adverse events from prior therapies.
- Stable/treated brain metastases.
TIL Therapy Cost by Region
Self-pay international patient estimates. We believe in full financial transparency to help you plan effectively.
| Region | Estimated Cost (USD) | What's Typically Included | Notes |
|---|---|---|---|
| 🇨🇳 China | $80,000 – $120,000 Clinical research programs | TIL manufacturing, lymphodepletion, infusion, IL-2, hospital stay | Multiple specialized centers in Beijing, Shanghai, Guangzhou |
| 🇸🇬 Singapore | $100,000 – $150,000 Private centers | Full episode of care, English-speaking multidisciplinary teams | Established TIL programs at major cancer centers |
| 🇺🇸 USA (Amtagvi) | $375,000+ Drug list price only | Drug only; hospital, ICU, IL-2 add $100K-$200K+ | Total episode often $500K-$700K. Highly insurance-dependent. |
Costs above reflect the treatment episode. They do NOT include international airfare, accommodation for you or a companion, pre-treatment diagnostics, or post-treatment follow-up scans. Our coordination team provides a detailed, itemized estimate after reviewing your case.
From Review to Infusion: 6-10 Weeks
TIL therapy requires more time than some other therapies due to surgical harvest and extended manufacturing. Plan for 2-3 weeks in-country.
Medical Records Review & Center Matching
Share your pathology reports and treatment history. Our independent oncology coordinators conduct a peer review and match you to appropriate TIL centers within 48 hours.
Travel & Surgical Tumor Resection
Travel to the destination country. A surgical procedure (often outpatient or 1-night stay) obtains the tumor tissue, which is then shipped to the GMP manufacturing lab.
TIL Manufacturing & Expansion
TILs are isolated and expanded over 22-33 days. You may return home or stay near the treatment center while quality control testing is performed.
Admission, Lymphodepletion & Infusion
Hospital admission for 3 days of lymphodepleting chemotherapy, followed by the one-time TIL infusion, and up to 12 doses of IL-2 over 5 days with close monitoring.
Follow-Up & Response Assessment
First response scan at 4-8 weeks post-infusion. You return home with a clear, coordinated follow-up plan for your local oncologist.
Side Effects: What to Expect
TIL therapy is intensive, and transparency about side effects is crucial for your peace of mind. Most effects are temporary and carefully managed by experienced medical teams.
Cytokine Response (from IL-2)
Fever, chills, fatigue, and nausea are common during IL-2 administration. These typically resolve within 24-48 hours of stopping IL-2.
ManageableCapillary Leak Syndrome
IL-2 can cause fluid to shift from blood vessels, leading to low blood pressure or edema. This is why ICU-capable monitoring is a strict requirement.
Requires ICU MonitoringProlonged Cytopenias
Low white cells, red cells, and platelets for 1-3 weeks due to lymphodepletion. Infection risk is proactively managed with prophylactic medications.
Expected & MonitoredTIL vs Other Cellular Therapies
Each advanced therapy has distinct strengths. Understanding these helps you and your doctor make the most informed decision.

Frequently Asked Questions
Honest, clear answers based on published clinical data and our coordination experience.
TIL (Tumor-Infiltrating Lymphocyte) therapy is a personalized immunotherapy. It uses your body's own immune cells that have already recognized your tumor. A small tumor sample is surgically removed, TILs are extracted and multiplied to billions in a specialized lab, and then returned to your body to fight the cancer with renewed strength.
Costs vary significantly by region. In the USA, the drug list price is around $375,000, with total care often exceeding $500,000. In China, TIL therapy is available through clinical research programs ranging from $80,000 to $120,000. Singapore offers established programs between $100,000 and $150,000. These are self-pay international patient estimates.
While FDA approval is currently limited to melanoma, TIL therapy is being actively investigated in clinical trials for cervical cancer, head and neck cancers, non-small cell lung cancer, and breast cancer. Access to TIL for non-melanoma indications is currently through clinical trials in specialized centers in Asia and select academic institutions globally.
