Summary
Lifileucel, a tumor-infiltrating lymphocyte (TIL) therapy, was approved in February 2024 for unresectable melanoma. This review covers TIL therapy history and future research to enhance its effectiveness.
Area of Science:
- Oncology
- Immunotherapy
- Cellular Therapy
Background:
- Adoptive cell therapy using tumor-infiltrating lymphocytes (TILs) has been researched for decades.
- Unresectable melanoma remains a challenging cancer to treat effectively.
Purpose of the Study:
- To review the historical development of TIL therapy for melanoma.
- To highlight recent advancements and ongoing research in improving TIL therapy.
Main Methods:
- Literature review of key historical data on TIL therapy.
- Analysis of ongoing research efforts to enhance TIL efficacy and applicability.
Main Results:
- Lifileucel, a TIL-based therapy, received FDA approval in February 2024.
- Significant progress has been made over 30 years in TIL therapy research.
Conclusions:
- The approval of lifileucel marks a major milestone in adoptive cell therapy for melanoma.
- Continued research is crucial for optimizing TIL therapy for broader patient benefit.

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
