The Hidden “Anti-Cancer Weapon” in Tumor Tissue – TIL Cells
### The Hidden “Anti-Cancer Weapon” in Tumor Tissue – TIL Cells
TIL Therapy
**TIL Cells: Turning Tumor Tissue “Waste” into Treasure**
Lymphocytes are a crucial part of the immune system. They can be found both in the periphery and within tumor tissues, serving as the body’s natural defense against tumor cells. Traditionally, only a small portion of excised tumor tissue is used for pathological diagnosis, while the majority is discarded as medical waste. This practice wastes the valuable anti-cancer resources hidden within the patient’s own body!
Tumor-Infiltrating Lymphocyte (TIL) therapy involves extracting lymphocytes from the tumor biopsy tissue of cancer patients. Using DNA sequencing technology, these lymphocytes surrounding the tumor cells are collected, expanded, and cultured in vitro before being reinfused into the patient. TIL therapy has shown positive clinical outcomes in various solid tumors, such as non-small cell lung cancer, melanoma, colorectal cancer, ovarian cancer, cervical cancer, and head and neck cancers. Compared to other T-cell therapies like CAR-T and TCR-T, TIL therapy offers broader targeting, more precise recognition, and more enduring anti-cancer effects.
**Applications of TIL Cells**
1. **For Early-Stage Cancer Patients:** TIL cells can be used as adjuvant therapy after surgery, helping to eliminate residual cancer cells following traditional treatments like surgery, radiotherapy, and chemotherapy, thereby preventing tumor recurrence or metastasis.
2. **For Advanced Cancer Patients:** TIL cells can serve as a last-line salvage treatment, aiding in extending survival time, improving quality of life, and addressing the dilemma of “no available drugs” for late-stage cancer patients.
**The Relationship Between TIL Cells and Cancer Patient Prognosis**
Using “non-small cell lung cancer” (#NSCLC) as an example, we can explore the impact of peripheral and tumor-infiltrating lymphocytes (TIL cells) on the prognosis of cancer patients.
A hospital in Tianjin, China, collected peripheral blood and tumor tissue samples from 105 newly diagnosed and untreated stage III/IV NSCLC patients. They analyzed the overall composition of peripheral blood cells and TIL cells, calculating and analyzing the overall survival (OS) of all patients. The results were as follows:
1. The median overall survival (mOS) for all patients was 12 months. The 1-year, 2-year, and 3-year overall survival (OS) rates were 60.5%, 28.4%, and 18.6%, respectively.
2. Patient OS was related to tumor size, tumor pathology, and CRP levels.
– **Tumor Size:** Patients with tumor lesions smaller than 4.8 cm had significantly longer OS compared to those with lesions larger than 4.8 cm (p=0.040).
– **Tumor Pathology:** Patients with squamous cell carcinoma had significantly longer OS compared to those with adenocarcinoma (p=0.025).
– **CRP Levels:** Patients with CRP levels below 8.29 mg/L had significantly longer OS compared to those with higher CRP levels (p=0.011).
– **Tumor CD4+ and CD8+ T Cell Infiltration:** Patients with higher levels of tumor CD4+ and CD8+ T cell infiltration had significantly longer survival compared to those with lower infiltration levels (p<0.0001 and p=0.011, respectively).
In conclusion, in newly diagnosed stage III/IV NSCLC patients, OS is associated with increased numbers of peripheral lymphocytes, CD4+ TIL, and CD8+ TIL, and is positively correlated with several basic clinical factors. This highlights the necessity of timely TIL cell storage. Patients are advised not to waste their valuable anti-cancer immune cells.
**Timing of TIL Cell Storage**
Generally, TIL cells should be stored as early as possible, ideally before receiving other treatments like radiotherapy or chemotherapy. At this stage, TIL cells have the strongest anti-cancer capability for the following reasons:
1. **TIL Cell Quantity:** TIL cell numbers gradually decrease as the tumor progresses. Clinical studies on TIL cell therapy for melanoma have found that T cell and NK cell numbers significantly decrease with tumor progression.
2. **Postoperative Adjuvant Radiotherapy and Chemotherapy:** These treatments not only kill cancer cells but also destroy immune cells and normal cells, reducing the anti-cancer efficacy of immune cells. Clinical studies on TIL cell therapy for cervical cancer have shown that CD4+ and CD8+ cell numbers significantly decrease in late-stage tumor TIL cells.
Therefore, patients are encouraged to seize their precious and unique opportunity for anti-cancer treatment. With the consent of their primary physician, they should preserve fresh tumor tissue samples preoperatively and entrust professional institutions with TIL cell isolation, culture, and cryopreservation. This can be used for postoperative adjuvant therapy to eliminate residual cancer cells, prevent tumor recurrence, or serve as a last-line salvage treatment for advanced cancer patients.
Since its initial clinical application in 1988, TIL therapy has developed over more than thirty years. Compared to other T-cell therapies, TIL therapy has the unique advantage of turning the patient’s own tumor tissue “waste” into a valuable resource, offering unique benefits in treating solid tumors and even helping some patients achieve long-term survival with the tumor.
China’s TIL therapy has been specially modified based on the American tumor-infiltrating lymphocyte (TIL) therapy to enhance TIL cell self-expansion ability and overcome the tumor microenvironment. In recent years, several new TIL therapies have been developed in China. Notably, the two TIL therapies showcased at the 2024 ASCO conference not only demonstrated impressive efficacy but also featured one therapy that requires neither lymphodepletion nor IL-2 treatment, significantly improving safety and cost-effectiveness!
The good news is that several TIL therapies have been officially approved for clinical research in China, targeting various solid tumors such as non-small cell lung cancer, cholangiocarcinoma, esophageal cancer, cervical cancer, ovarian cancer, and breast cancer.

🌟✨ **Breakthrough! Chinese Novel CAR-T Therapy Kills Tumors and Prevents Relapse!** ✨🌟
CAR-T Therapy
🔬 On January 2, 2024, a groundbreaking clinical study from China was published in *Nature*. This study, employing engineering design, enables CAR-T cells to secrete Interleukin-10 (IL-10), thereby enhancing metabolism within the tumor microenvironment. The modified IL-10 CAR-T cells increase oxidative phosphorylation in a mitochondrial acetoacetate carrier-dependent manner, resulting in complete regression of solid tumors and metastatic cancers, including colon cancer, breast cancer, melanoma, and pancreatic cancer. This breakthrough research offers new hope for cancer patients.
🌱 **The Miracle of IL-10** 🌱
The secretion of IL-10 promotes the proliferation and effector functions of CAR T cells, leading not only to the regression of solid tumors but also inducing stem cell-like memory responses in lymphoid organs, providing enduring protection against tumor re-attack. Specifically, IL-10 HER2 CAR-T cells achieved complete regression of MC38-HER2 tumors in mice, with a cure rate of 90%. In the case of melanoma, IL-10 TRP-1 CAR-T cells achieved a clearance rate of 60%, with significant success in treating the orthotopic B16F10 melanoma model.
🦠 **A Weapon against Relapse** 🦠
In addition to complete regression of solid tumors, IL-10 CAR-T cells demonstrated the ability to prevent relapse in immunodeficient mice. Mice treated with IL-10 CD19 hCAR-T cells for Raji or PANC1-CD19 tumors exhibited complete tumor regression without relapse, indicating stronger anti-tumor capabilities of IL-10 CAR-T cells in xenograft models. Particularly noteworthy is the effective elimination of pancreatic ductal adenocarcinoma (PDAC) tumors by IL-10 CD19 hCAR-T cells, resulting in complete response in all treated mice.

Revolutionizing Medicine: CAR-T Therapy Beyond Cancer
🚀Revolutionizing Medicine: CAR-T Therapy Beyond Cancer 🚀
🔬 Over the past decade, CAR-T cell therapy has transformed the field of oncology, successfully treating previously incurable blood cancers. While CAR-T therapy gained fame for its success in cancer treatment, the roots of this groundbreaking principle trace back nearly 30 years—initially exploring T cell therapy for HIV/AIDS. Although the early attempts didn’t succeed in treating HIV/AIDS, they demonstrated the enduring potential of engineered T cells in immunocompromised patients.
🌟 CAR-T therapy, or Chimeric Antigen Receptor T-cell Immunotherapy, essentially involves reengineering a patient’s immune T cells outside the body to recognize antigens on the surface of tumor cells. These modified cells are then reintroduced into the patient, effectively identifying and eliminating cancer cells. Scientists have been tirelessly working to extend CAR-T therapy beyond blood cancers to various other types.
💡 Moreover, research from both clinical and preclinical studies indicates that CAR-T therapy holds great promise beyond cancer treatment. It shows potential applications in autoimmune diseases, chronic infections, heart diseases, aging-related conditions, and more.
🌐 In recent years, scientists have focused on applying CAR-T therapy to solid tumors, exploring its potential in cancer types beyond blood-related malignancies. Early research results suggest that the next frontier for CAR-T therapy may extend to various fields outside cancer, including autoimmune diseases (systemic lupus erythematosus, pemphigus vulgaris, multiple sclerosis, type 1 diabetes, asthma), fibrotic diseases (fibrosis in the heart, liver, lungs, and kidneys), aging-related conditions (liver fibrosis, solid tumors, atherosclerosis, natural aging), and infectious diseases (HIV/AIDS, hepatitis B and C, pulmonary tuberculosis).
🚀 The future of CAR-T therapy holds vast potential in reshaping the landscape of medical treatment, reaching far beyond the realms of cancer. Stay tuned for ground

Global First: Chinese CAR-T Therapy Simultaneously Cures Tumor and Lupus Erythematosus
China make advanced medical treatment affordable
Wang Fang (pseudonym), residing in Yichang, Hubei, China, underwent a life-threatening ordeal. This patient in her forties had been suffering from systemic lupus erythematosus for over 20 years. What exacerbated her agony was the excruciating pain in her right leg since June 2019, which forced her into a wheelchair. Local hospital diagnosis revealed an aggressively invasive tumor—diffuse large B-cell lymphoma.
In mid-August 2019, Wang Fang followed a relative’s advice and sought treatment at Peking University Shenzhen Hospital (hereinafter referred to as “PKU Shenzhen Hospital”) in Shenzhen, where she was fortunate to participate in clinical trials for blood tumors. In mid-September 2019, she underwent the compound dual-target CAR-T (CD19/BCMA) cell immunotherapy.
Miraculous changes occurred a month after treatment; her lymphoma vanished entirely. Two months later, she was freed from the wheelchair and could walk independently. The nine-month follow-up, more astonishingly, revealed not only the complete disappearance of lymphoma but also the reversal of her long-standing stubborn lupus erythematosus antibodies, signifying her clinical cure from lupus.
This is the first documented instance globally where compound dual-target CAR-T cell immunotherapy cured diffuse large B-cell lymphoma and refractory lupus erythematosus—a significant breakthrough in Shenzhen’s oncology clinical research and treatment field.
This patient, originally from another region, had relied on steroids and other drugs to manage her condition for over 20 years due to systemic lupus erythematosus. However, the intensified pain in her right leg in June 2019 led to the diagnosis of an invasive tumor, rapidly deteriorating her condition and confining her to a wheelchair.
When faced with chemotherapy recommendations at the local hospital, Wang Fang declined due to the side effects she had previously experienced. Fortunately, a relative’s recommendation brought her to PKU Shenzhen Hospital. With the doctors’ dedicated assistance, Wang Fang participated in the clinical trial of CAR-T cell immunotherapy.
CAR-T cell therapy is an advanced treatment method that transforms a patient’s own T cells into CAR-T cells capable of identifying and attacking tumor cells. Since its successful treatment of the first case of acute lymphoblastic leukemia in the United States in 2012, this treatment has gradually become a groundbreaking technology in the field of tumor therapy. The Blood Department of PKU Shenzhen Hospital, as a pioneer, has completed over 30 cases of CAR-T cell therapy clinical trials, offering hope for those patients in critical conditions with ineffective traditional treatments.
Considering the uniqueness of Wang Fang’s disease, the team designed a compound dual-target CAR-T cell immunotherapy targeting both CD19 and BCMA. The success of this advanced therapy made Wang Fang the first case globally to be cured of lupus erythematosus using CAR-T cell therapy.
One month after treatment, she no longer needed wheelchair assistance; two months later, she could walk independently; and nine months later, besides the complete eradication of the tumor, the lupus erythematosus-related antibodies turned negative, leading to her clinical cure without relying on medication for her daily life.
Director Zhang Hongyu from the Blood Department of PKU Shenzhen Hospital stated that this successful case marks a significant breakthrough in CAR-T cell therapy, offering the possibility of cure to more patients. This successful clinical trial was also reported at the 61st American Society of Hematology (ASH) Annual Meeting, highlighting PKU Shenzhen Hospital’s significant contributions to the medical field.
After enduring this arduous battle, Wang Fang has regained her health and freedom.
