Abstract:
Melanoma is the most aggressive skin cancer and its incidence is gradually increasing worldwide. Patients with metastatic melanoma have a very poor prognosis (estimated 5-year survival rate of <16%). In the last few years, several drugs have been approved for malignant melanoma, such as tyrosine kinase inhibitors and immune checkpoint blockades. Although new therapeutic agents have improved progression-free and overall survival, their use is limited by drug resistance and drug-related toxicity. At the same time, adoptive cell therapy of metastatic melanoma with tumor-infiltrating lymphocytes has shown promising results in preclinical and clinical studies. In this review, we summarize the currently available drugs for treatment of malignant melanoma. In addition, we suggest cytokine-induced killer (CIK) cells as another candidate approach for adoptive cell therapy of melanoma. Our preclinical study and several previous studies have shown that CIK cells have potent anti-tumor activity against melanomas in vitro and in an in vivo human tumor xenograft model without any toxicity.
Insights
Metastatic melanoma is a deadly cancer. Cytokine-induced killer (CIK) cells show potent anti-tumor activity and may offer a new adoptive cell therapy option for melanoma patients, with no observed toxicity.
Area of Science:
- Oncology
- Immunology
- Dermatology
Background:
- Melanoma incidence is rising globally, with metastatic melanoma carrying a poor prognosis.
- Approved therapies like tyrosine kinase inhibitors and immune checkpoint blockades improve survival but face limitations due to resistance and toxicity.
- Adoptive cell therapy using tumor-infiltrating lymphocytes shows promise for metastatic melanoma treatment.
Purpose of the Study:
- To review current drug treatments for malignant melanoma.
- To propose cytokine-induced killer (CIK) cells as a potential adoptive cell therapy for melanoma.
- To highlight the anti-tumor efficacy and safety of CIK cells in preclinical models.
Main Methods:
- Literature review of existing melanoma therapies.
- Summary of preclinical and clinical data on adoptive cell therapy.
- Presentation of preclinical findings on CIK cell activity against melanoma.
Main Results:
- Current therapies for malignant melanoma have limitations including drug resistance and toxicity.
- Cytokine-induced killer (CIK) cells demonstrate potent anti-tumor activity against melanoma.
- Preclinical studies indicate CIK cells are effective in vitro and in vivo without toxicity.
Conclusions:
- Existing treatments for metastatic melanoma require further improvement.
- Cytokine-induced killer (CIK) cells represent a promising candidate for adoptive cell therapy in melanoma.
- CIK cell therapy offers a potentially safe and effective alternative for melanoma treatment.
