Colorectal Cancer

A Chinese medical team has made a significant breakthrough in the treatment of dMMR (deficient mismatch repair) metastatic colorectal cancer. Recently, their latest research findings were published in the Med journal, a subsidiary of Cell, offering new treatment hope for patients with advanced colorectal cancer.

The study revealed that the combination of PD-1 antibody immunotherapy with COX inhibitors, drugs commonly used for anti-inflammatory treatment, significantly improved treatment effectiveness. This innovative strategy could substantially increase survival chances for patients with advanced colorectal cancer.

Colorectal cancer is the second most common cancer in China, and its incidence is on the rise. While PD-1 antibody immunotherapy has brought hope to some patients, its success rate is only 45%. Approximately 30% of dMMR metastatic colorectal cancer patients are resistant to PD-1 treatment. Therefore, the Chinese team explored combining PD-1 immunotherapy with COX inhibitors (such as celecoxib and aspirin) to overcome this resistance.

The team’s Phase 2 clinical trial yielded remarkable results. Among the 30 patients who received the combination therapy, the overall response rate was 73.3%, a 30% improvement over PD-1 monotherapy. After more than four years of follow-up, 65% of patients achieved progression-free survival, and 90% were still alive. Four patients reached complete remission, while 11 others underwent surgery, with 10 showing complete pathological remission.

In addition to the notable clinical outcomes, genomic and immunological analysis revealed that high expression of the TAPBP protein was associated with better treatment results. This discovery opens new avenues for the development of biomarkers to predict treatment response and for personalized treatment plans in the future.

Following the publication of the study, it attracted significant attention from the international medical community. Experts from Memorial Sloan Kettering Cancer Center in the U.S. wrote a commentary in the Med journal, highly praising the innovative therapy. They noted that the combination of COX inhibitors with PD-1 treatment not only increased the complete remission rate but also reduced immune suppression signals in the tumor microenvironment, enhancing the effectiveness of PD-1 therapy, with manageable side effects.

This research offers new hope for dMMR metastatic colorectal cancer patients worldwide, and further large-scale clinical trials are expected to confirm its efficacy. The combination of COX inhibitors with PD-1 immunotherapy could become a safe and effective treatment option for dMMR metastatic colorectal cancer patients, providing hope for long-term survival.

🎉💉 Exciting Breakthrough Alert! Chinese Medical Team Unveils Game-Changing mRNA Cancer Vaccine 🎉💉

Advanced Science

Say hello to the future of cancer treatment! A groundbreaking mRNA cancer vaccine jointly developed by Chinese scientists has hit the spotlight, promising to elevate tumor suppression rates and extend survival periods.

🔬 What’s the Buzz? 🔬
Published in the prestigious journal “Advanced Science”, the research titled “All-Trans-Retinoic Acid-Adjuvanted mRNA Vaccine Induces Mucosal Anti-Tumor Immune Responses for Treating Colorectal Cancer” reveals a novel mRNA cancer vaccine. This vaccine, packaged with lipid nanoparticles (LNPs), delivers All-Trans-Retinoic Acid (ATRA) and mRNA, effectively stimulating mucosal immune responses in the intestines. Compared to conventional mRNA-LNP vaccines, this innovative approach significantly boosts tumor suppression and prolongs survival rates.

🩺 Why It Matters 🩺
Colorectal cancer ranks third in cancer incidence and second in mortality globally. Conventional treatments such as surgery, chemotherapy, and radiation often come with high recurrence rates. Enter cancer immunotherapy—the beacon of hope in the fight against colorectal cancer. Cancer vaccines, a vital component of immunotherapy, harness the body’s immune system to target and destroy cancer cells. With the recent success of mRNA vaccines for COVID-19, mRNA cancer vaccines have garnered immense attention for their potential to revolutionize cancer treatment.

🚀 The Breakthrough 🚀
The key lies in ATRA-LNP’s ability to induce cytotoxic T cells in the intestines, offering a promising therapeutic approach for colorectal cancer. In animal models, ATRA-LNP treatment led to a remarkable reduction in tumor growth and extended survival rates compared to conventional treatments. These findings underscore the potential of mRNA cancer vaccines, particularly in enhancing the treatment outcomes for colorectal cancer patients.

🌟 The Takeaway 🌟
With its ability to activate anti-tumor immune responses at mucosal surfaces, the novel mRNA cancer vaccine brings hope for improved outcomes in colorectal cancer treatment. ATRA incorporation into LNPs not only enhances mRNA delivery efficiency but also directs activated T cells towards the intestines, amplifying their anti-tumor effects. This study paves the way for a promising future in enhancing the efficacy of mRNA cancer vaccines against colorectal cancer.

A Chinese research team has made significant advancements in the treatment of colorectal cancer, paving the way for a new milestone in the field of oncology treatment

In recent years, natural killer (NK) cell immunotherapy has gained significant attention as a promising approach for treating solid tumors and malignant tumors of the blood system. NK cells, constituting 5% to 15% of lymphocyte circulation, are regarded as natural warriors against cancer, capable of directly identifying and killing cancer cells.

Umbilical cord blood NK cells bring new treatment options for colorectal cancer patients!

In a paper published in the journal “Human Gene Therapy” by a Chinese research team, researchers successfully expanded NK cells from umbilical cord blood (UCB) by utilizing membrane-bound interleukin (IL)-21, naming them eUCB-NK cells. Animal experiments demonstrated the robust in vivo anti-tumor activity of umbilical cord blood NK cells, suitable for late-stage colorectal cancer patients. Combining with bevacizumab can enhance NK cell infiltration, leading to improved therapeutic outcomes.

Moreover, CAR-NK therapy holds considerable promise. By genetically engineering chimeric antibodies into NK cells, they become capable of recognizing and destroying tumor cells. Safety and efficacy have been demonstrated in the treatment of colorectal cancer.

A study focusing on metastatic colorectal cancer revealed that local infusion of NKG2D mRNA CAR-NK cells led to rapid tumor reduction in patients, with no significant adverse events observed during the treatment process, introducing a novel strategy for tumor immunotherapy.
