Cancer stem-like cells in uveal melanoma: novel insights and therapeutic implications

Area of Science:

• Ophthalmology
• Oncology
• Cancer Biology

Background:

• Uveal melanoma (UM) is the most frequent primary ocular tumor in adults.
• While primary UM is treatable, ~50% of patients develop life-threatening liver metastasis.
• Current therapies show limited efficacy against UM metastasis and resistance.

Purpose of the Study:

• To review the current understanding of cancer stem-like cell (CSC) biology in UM.
• To explore the role of CSCs in UM treatment failure and metastasis.
• To discuss CSCs as potential therapeutic targets for UM.

Main Methods:

• Literature review of preclinical and clinical studies on UM and CSCs.
• Analysis of molecular pathways and mechanisms associated with UM CSCs.
• Synthesis of current knowledge on CSC biology in uveal melanoma.

Main Results:

• CSCs are identified as a key factor in UM resistance to chemotherapy and targeted therapies.
• CSCs contribute significantly to the hematological dissemination and metastasis of UM.
• Emerging research has identified specific molecular pathways in UM CSCs.

Conclusions:

• CSCs represent a major challenge in treating uveal melanoma effectively.
• Targeting CSCs holds promise for overcoming therapeutic resistance and improving patient survival.
• Further research into UM CSC biology is crucial for developing novel treatment strategies.
