Summary
This study identifies two distinct acral melanoma subtypes with different clinical behaviors and molecular mechanisms. A biomarker panel accurately distinguishes these subtypes, offering new insights for acral melanoma treatment.
Area of Science:
- Oncology
- Genomics
- Immunology
Background:
- Acral melanoma is an aggressive subtype with poor prognosis.
- Its molecular drivers remain poorly understood, complicating clinical management.
Purpose of the Study:
- To elucidate the molecular landscape of acral melanoma.
- To correlate molecular subtypes with clinical features and prognosis.
Main Methods:
- Multi-omics data analysis and network-based algorithms were employed.
- Single-cell RNA sequencing (scRNA-Seq) analyzed immunocyte contributions.
- Clinical samples validated subtype-prognosis correlations and macrophage interactions.
Main Results:
- Two distinct acral melanoma subtypes with differing clinical behaviors were identified.
- A biomarker panel (EREG, VSIG4, FCGR3A, RAB20) achieved 0.946 AUC for subtype distinction.
- Subtype I shows favorable prognosis; Subtype II is high-risk with dermal invasion, linked to specific macrophage populations.
Conclusions:
- Findings enhance understanding of acral melanoma molecular landscape and clinical management.
- Distinct subtypes and potential therapeutic targets were identified.
- Further validation in diverse cohorts is recommended.
