Malignant melanoma is a disease with an unpredictable evolution. Detected in stage I and II has a great chance to cure, if it is correctly treated: excisional biopsy with safety margins in accordance with tumor thickness. Lymphoscintigraphy with sentinel node identification and biopsy became compulsory for staging malignant melanoma, the role of complete lymphadenectomy would be established by publishing the MSLTII data. The sentinel node is analysed using more and more sophisticated techniques (RT-PCR) in order to detect isolated tumoral cells, although their clinical significance is not known yet. Metastases occurrence is a dramatic phenomenon because chemotherapy, radiotherapy or biologic therapy have insignificant results. The only therapeutic modality which may increase survival in this situation is surgery for some carefully selected patients.

Therapies against hematological malignancies using chimeric antigen receptors (CAR)-T cells have shown great potential; however, therapeutic success in solid tumors has been constrained due to limited tumor trafficking and infiltration, as well as the scarcity of cancer-specific solid tumor antigens. Therefore, the enrichment of tumor-antigen specific CAR-T cells in the desired region is critical for improving therapy efficacy and reducing systemic on-target/off-tumor side effects. Here, we functionalized human CAR-T cells with superparamagnetic iron oxide nanoparticles (SPIONs), making them magnetically controllable for site-directed targeting.

Individuals with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) have a high risk of developing other malignancies (OMs). The development of OMs may be associated with the advanced age of CLL/SLL patients, presence of a tumor-promoting microenvironment, immune alterations inherent to CLL/SLL, or chemotherapy. Importantly, the occurrence of OMs following frontline fludarabine, cyclophosphamide and rituximab (FCR) treatment is associated with a reduction in the overall survival (OS).

To gain a better understanding of the influence of ncRNAs on gene regulation during melanoma progression, we mapped the landscape of ncRNAs in melanocytes and melanoma cells. Nearly half of deregulated genes in melanoma are ncRNAs, with antisense RNAs (asRNAs) comprising a large portion of deregulated ncRNAs.
