THE TIL THERAPY
TREATMENT PROCESS
Seven stages, weeks of preparation, and a carefully ordered sequence. Here is what TIL therapy actually involves โ so you can go in with eyes open.
The Full TIL Therapy Sequence
TIL therapy moves through these stages in order. Each sets up the next โ the biological sequence cannot be shortened.
- 1
Initial Consultation and Eligibility Workup
Medical records, imaging, and lab results reviewed. Specialists confirm eligibility. Informed consent completed.
- 2
Tumor Tissue Collection
A surgical team removes a tumor sample. The lab team is already in coordination before this happens.
- 3
Laboratory Cell Expansion
Billions of TIL cells grown specifically from your tumor over 4-6 weeks. While you wait, something is being built for you.
- 4
Lymphodepletion Chemotherapy
A 5-7 day inpatient chemotherapy course depletes existing immune cells to make room for incoming TIL cells.
- 5
TIL Cell Infusion
The expanded cells are delivered intravenously โ similar to a blood transfusion. Patient is already admitted.
- 6
IL-2 Support Therapy
Interleukin-2 given after infusion to sustain TIL cells. Causes fever, fatigue, fluid shifts โ managed continuously in hospital.
- 7
Recovery and Response Assessment
Immune system rebuilds. Imaging at 6-8 weeks assesses tumor response. Regular monitoring continues at set intervals.
Key Timeline Facts
- 4-6 wksCell Expansion WindowMinimum time required to grow viable TIL cells โ cutting this short undermines quality.
- 24 hrsInfusion Window After ChemoTIL cells must be infused within 24 hours of completing lymphodepletion โ biologically time-sensitive.
- 10-14 daysHospital AdmissionInpatient stay around conditioning and infusion phases โ not optional, not abbreviated.
Planning Considerations Patients Often Overlook
Some phases are inpatient; others are outpatient. Plan for both. If traveling internationally, expect to be near the treatment center for several weeks during active phases. Your local oncologist and the treating center should be in active communication throughout.

How CancerFax Helps
CancerFax is a specialist cancer access and patient-navigation platform. We help patients and families understand their options, organise medical records, coordinate hospital communication, and support cross-border treatment planning where appropriate.
We help collect and organise reports, scans, pathology, biomarker results, and treatment history for structured case review.
We communicate with hospitals or trial teams to assess whether a case may be suitable for further screening.
We support appointment coordination, document submission, translation, and direct communication with international departments.
For international patients, we help with practical coordination โ travel planning, hospital admission guidance, and local support.
If this option is not suitable, we help explore other relevant treatments, clinical trials, or advanced care pathways.
From inquiry through to follow-up, our coordinators provide a single point of contact for the family.
CancerFax does not guarantee treatment access, eligibility, or clinical outcome. Our role is to help patients access accurate information, structured review, and appropriate specialist pathways.
